Toy, motor-driven, convertible wood-working type machine shop tools are available. While generally satisfactory, these prior art toys do have certain disadvantages.

One disadvantage resides in the fact that certain of these prior art toys employ simulated saws, drills and the like which are incapable of performing actual wood-working operations with the result that a child soon becomes bored with them.

Although certain other prior art toys of this type employ saws, drills and the like which are capable of performing wood-working operations, they have the disadvantage that the average child experiences diiculty in setting up the toy for a particular operation and in operating the toy to turn out a finished product having a desired form.

In view of the foregoing factors and conditions characteristic of toy machine shop tools, it is a primary object of the present invention to provide a new and useful toy machine shop tool of the wood-working type not subject to the disadvantages enumerated above and having tool-holder means adapted to cooperate with template `means for minimizing the skill required to perform wood-working operations and accurately reproduce objects such as table legs with the machine efficiently, safely and expeditiously.

Another object of the present invention a toy, motor-driven, convertible chine shop tool.

Yet another object of the vide a new and useful described.

Still another object of the present invention is to provide a new and improved holder for a toy, lathe tool-bit which co-acts with a template of the present invention to guide the tool-bit during wood-working operations.

A further object of the present invention is to provide a new and useful live center for a toy lathe.

A still further object of the present invention is to provide a toy of the type described which may be converted from a lathe to a drill press by a child safely, eiiciently and expeditiously.

Another object of the present invention is to provide a new and useful toy jig saw.

Yet another object of the present invention is to provide a new and useful toy bench saw. i

Another object of the present invention is to provide a new and useful toy table sander.

According to a rst embodiment of the present invention, a toy, motor driven, convertible wood-working type machine shop tool is provided which comprises a motor driven head-stock, a bed plate and a tail-stock. A safety handle is provided which can be slidably mounted on the bed and used as a tool holder for ya lathe toolbit when the toy is used as a lathe. When so` used, a feeler is attached to the safety handle Where it co-acts with a template mounted on the bed to guide the tool during wood-working operations.

is to provide wood-working type mapresent invention is to prosafety handle for a toy of the type The lathe can be converted to a jig saw by rotating the head-stock, bed plate and tail-stock assembly degrees so that the bed is upper most. The safety handle is then attached to the bed in such a manner that it serves as an arm for supporting a leaf spring. A jig saw blade -may then be connected to the spring and to a sliding block on the head-stock which reciprocates the blade.

The head-stock is slidably mounted on ways on the bed and may be either locked to the ways for certain 0perations or left free to be slid along the ways when the head-stock is used as a drill press. When so used, the safety handle is attached to the head-stock to move it into engagement with the Work being drilled.

A circular saw and a sanding head are `also provided. These tools may be driven by the head-stock when the bed is in its upper most position. The bed includes an opening through which the sanding disc and the circular saw extend in such a manner that the bed serves `as a work supporting table.

According to a second embodiment of the present invention, a motor driven head-stock, a bed plate and a tail-stock are provided. The head-stock is slidably mounted on the bed plate and is spring-loaded against stops at one end thereof by suitable spring means. The tail-stock is removably mounted on the other end of the bed plate and is adapted to be connected to the headstock for use as a table when the device is used as a circular saw, a jig saw or a sanding machine.

A safetyV handle similar to that used with the first embodiments is also provided for use in the manner mentioned above in connection with the first embodiment. In addition, the feeler of the second embodiment may also be used as a fence for sawing operations.

The tail stock is provided with suitable legs which may be used to support the bed plate and head-stock vertically for drill press operations. During such operations, the safety handle is connected to the head-stock for moving it downwardly into engagement with a work piece against the bias of the spring means which minimizes the force required to return the head-stock to its elevated position.

An important feature of the second embodiment of the present invention resides in a live-center which may be used in combination with the tail stock to compensate for misalignment of a work piece during lathe operations.

The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages thereof, may best be understood by reference to the following description, taken in connection with the accompanying drawings in which like reference characters refer to like elements in the several Views.

Referring again to the drawings and particularly FIG- URES 1-4, a toy, motor-driven, convertible, wood-working type machine shop tool, generally designated 10, includes abed 12, a motor-driven, slida-bie head-stock 14 and axed tail stock 16.

Thebed 12 may be made from any suitable material such as plastic, sheet steel or extruded aluminum and includes abottom wall 18 and a pair of T-shaped, upstanding, parallel, spaced-apart ways 20 and 21 which are engageable 'at the will of the operator of thetoy 10 by a first pair of grooves orslots 22 provided at thelower end 24 of the head-stock 14 or by a second pair of slots orgrooves 26 provided at theupper end 28 thereof. Theways 20 and 21 are also engaged bygrooves 29 provided in tail-stock 16 which is aixed to thebed 12 byscrews 29a. The head-stock 14 is reciprocally mounted on theways 20 yand 21 and is biased to the left, as viewed in FIGURE 2, by acompression spring 30 which encompasses arod 32 having oneend 34 secured in the tail-stock 16 and on other end 36 slidably engaged by the head-stock 14. Thespring 30 minimizes the effort required to accurately position the head-stock 14, and facilitates employing thetoy 10 as a drill press, 'as will be hereinafter described.

The head-stock 14 may be locked to thebed 12 by alocking device 38 including a block 40 which is slidably mounted in the head-stock 14. The block 40 includes an elongated slot 42 through which an eccentric 44 extends. The eccentric 44 is rotatably mounted in the head-stock 14 and may be rotated by anover-throw lever 46. When lrot-ated in a clockwise direction, as viewed in FIGURE 2, the eccentric 44 forces the block 40 downwardly into engagement with theway 20. This securely locks the head-stock 14 to thebed 12 at any point along theways 20and 21.

T hetoy 10` is shown in FIGURES 1-4 in a form suitable for `operation as a lathe. Thetoy 10 is prepared for operation as a lathe by rotatably mounting a tail-stock bearing 48 in anaperture 50 provided in the tail-s-tock 16. The tail-stock bearing 48 includes a cylindrical =body portion 52 having an annular shoulder 54 formed at oneend 56 thereof. The tail-stock bearing 48 may be made from a suitable bearing material such as brass or from a plastic material having a low coeicient friction and is provided wi-th a counter bore orcavity 58 at itsend 56. A pin 60 is mounted in thecavity 58 at right angles to the major axis thereof, and is engageable by thebifurcated end 62 of alive center 64.

Thelive center 64 includes awood screw 66 so that it can be screwed into a sui-table work piece 68 made of wood, plastic or the like. Thebifurcated end 62 is an important feature of the invention because it permits swingably mounting thelive center 64 on the pin 60 to minimize the effect when thelive center 64 is not placed in the exact center of the longitudinal axis of thework piece 68.

When used as a lathe, thetoy 10 also includes alive center 70 having awood screw 72 which is engageable with thework piece 68 and abifurcated end 74 which is engageable with apin 76 iixedly mounted cross-wise in abore 78 provided in alathe drive 80. Thelathe drive 80 includes anenlarged face plate 82 to which asanding disc 83 may be aiiixed in a manner to be hereinafter described. The lathe drive also includes ahub 84 having a noncylindrical bore or cavity 86 engageable with non-cylindrical, motor output-shaft 88 provided on a motor 90' in the head-stock 14. Thehub 84 engages a atface 91 onIthe shaft 88 with a suitable friction fit so that thelathe drive 80 will be driven by theshaft 88. Themotor 90 is cooled by afan 90a, as more fully shown in FIGURE 13, and is supplied with power throughelectrical leads 92 and asuitable switch 94.

Thetoy 10 also includes asafety handle 96 having a C-shapedgrip portion 98. A channel-shaped cross bar is aflxed to oneend 102 of thegrip 98 and atool holder 104 is affixed to theother end 106 of thegrip 98. When thedevice 10 is to be operated as a lathe, a lathe tool-bit 108 is retained in position on thetool holder 104 by athumb screw 110. The skill required to manipulate thetool 108 in wood-working operations is minimized by employing atemplate 112 which may be mounted in asuitable slot 114 provided on theway 21. Thetemplate 112 is provided with asuitable design 116 on itsupper edge 117 forming a pattern which may -be followed by thetool 108 to reproduce thedesign 116 on thework piece 68. Thetool 108 is caused to follow thedesign 116 by a probe orfeeler 120` having oneend 122 affixed to the cross-arm or bar 100 and itsother end 124 engageable with thepattern 116 when thebar 100 is in engagement with theway 20. Thehandle 96 is rockably and slidably mounted on theway 20 by aridge 126 andlips 128 provided on the channel-shapedbar 100. Thefeeler 120 co-acts with thetemplate 112 to control the depth of cut obtainable with thetool bit 108 in such a manner that thepattern 116 is reproduced on thework piece 68, as shown in FIGURE 2.

The toy ordevice 10 may be readily converted from the lathe shown in FIGURES 1-4 -to a drill press by removing thetail stock bearing 48, thelathe drive 80, thelathe bit 108, theprobe 120 and thetemplate 112 after which thelocking mechanism 38 may be released so that thehead stock 14 is free to reciprocate on thebed 12.

Referring now to FIGURES 5-7, after the aforementioned parts have been removed and thelocking mechanism 38 has been released, thebar 100 is inserted into a clamp or saddle which is axed to the head-stock 14. Thebar 100 is retained in position in thesaddle 130 by asuitable thumb screw 132 after which the handle may be employed to move the head-stock 14 toward the tail-stock 16 against the pressure exetred by spring 30 (FIGURE 2) until adrill blade 134 engages awork piece 136 positioned on thebed plate 12 against the tail-stock 16. Thedrill 134 isf aligned with theaperture 50 so that the drill may pass through the tail-stock 16 after drilling a hole in thework piece 136. Thedrill 134 may be conveniently stamped from a suitable piece of sheet steel and includes abody portion 138 having a flat,depressed portion 140 engageable with thehat face 91 on theshaft 88 for rotation of thedrill bit 134 thereby. Thedrill 134 is also provided with asemi-cylindrical strap member 144 which encompasses thesemi-cylindrical portion 146 of theshaft 88. Thedrill 134 also includes ablade portion 148 which is provided with a sharpened tip 150 adapted to drill a hole in thework piece 136 when theblade 134 is rotated bymotor 90. Of course it will be apparent to those skilled in the art that the toy may also be used vertically as a drill press with the head-stock 14 uppermost and the tail-stock 16 serving as a base.

Referring now to FIGURES 8 and 1l, thetoy 10 may be readily converted to a bench sander or table saw by removing thehead stock 14 from thebed 12 and turning it over so that thegrooves 26 engage theways 20 and 21. Thehead stock 14 is slid to theend 152 ofbed 12 which is remote fromthetail stock 16 and then secured in position by actuating thelocking mechanism 38. This operation positions themotor shaft 88 adjacent aslot 154 which is provided in thebottom Wall 18 and through which theface plate 82 of thelathe drive 80 extends when thehub 84 engages theshaft 88. Thetoy 10 is then inverted so that thebottom wall 18 ofbed 12 becomes a table on which a work piece can be supported. In this position, thedevice 10 may be supported on a suitable surface by the top walls 141: and 16h ofhead stock 14 andtail stock 16, respectively. Thetail stock 16 and thehead stock 14 are of equal height so thebed 18 will be level in its inverted position.

Alternatively, a circular saw 158 having acylindrical hub 159, which is provided with anon-cylindrical bore 161 adapted to frictionally engage theshaft 88, may be substituted for thelathe drive 80 when it is desired to use thedevice 10 as a circular or table saw. Danger to a child operating thedevice 10 as a table saw may be minimized by providing the circular saw 158 in the form of an anti-kick up blade or a plaster cast cutter of types which are well known in the art. One such plaster cast cutter which may be used satisfactorily is that shown in Stryker Patent No. 2,427,580.

Referring now to FIGURES 9 and 10, thedevice 10 may be readily converted for operation as a jig saw by mounting thehead stock 14 on thebed 12 in its FIGURE 1 position so that thegrooves 22 engage theways 20 and 21. Thedevice 10 is then turned upside down from its FIGURE l position so that thebottom Wall 18 is again upper most. Also, thehead stock 14 is positioned on thebed 12 in such a manner that `a reciprocating jig saw drivingplate 160 is aligned with anaperture 162 provided near theend 152 of the bottom wall 18 (FIGURE 8). Thelocking mechanism 38 may then'be actuated to lock thehead stock 14 to thebed 12.

Theplate 160 is provided with anaperture 164 at oneend 166 which is engageable by aneccentric member 168 aflixed to themotor shaft 88 for rotation thereby. Rotation of the eccentric 168 causes theplate 160 to reciprocate withinsuitable guide members 170 which are aixed to thefront wall 176 of thehead stock 14. Aleaf spring 172 is afXed to theguides 170 in such a manner that ashoe 174 provided on thespring 172 bears against the plate 1,60 to maintain it in sliding contact with thefront Wall 176 of thehead stock 14. Theplate 160 and theguides 170 may be conveniently made from a suitable plastic having a low coeicient of friction to minimize the force required to reciprocate theplate 160. Theother end 176 of theplate 160 is provided With a saw-receivingblock 178 which is engaged by atransverse pin 180 provided on oneend 182 of ajig saw blade 184. Theother end 186 ofblade 184 also carries atransverse pin 188 which is engageable with thebifurcated end 190 of aleaf spring 192.

When thetoy 10 is employed as a jig saw, thehandle 96 serves as a support arm for the leaf spring l192 which may be connected to thehandle 96 by inserting theend 194 ofspring 192 into thetool holder 104 and retaining it in position by thethumb screw 110. Thehandle 96 is connected to the head-stock 14 by engaging thebar 100 in thesaddle 130 and tightening thethumb screw 132. When the motor (FIGURE 2) is energized to rot-ateshaft 88, the eccentric 168 causes theplate 160 to reciprocate with a short stroke thereby reciprocating theblade 184.

A toy, motor-driven, convertible wood-Working type machine shop tool constituting a second embodiment of the present invention, generally designated 10a. is shown in FIGURES 12-20. The tool 10a is shown in FIG- URES 12-15 in the form of a lathe and includes, generally, a head-stock 14a, a tail-stock 16a, and abed 12a. The head-stock 14a. includes anelectric motor 90 having ashaft 88, both of which may be identical to the same elements shown in conection with the first embodiment of the present invention. The head-stock 14a is provided with grooves or slots 22u which engageways 20a and 21a to reciprocally mount the head-stock 14a on thebed 12a above its bottom wall 18a. The head-stock 14a also includes ahousing 200 in which a spring 30a is coiled. The spring 30a has afirst end 202 which is affixed to the hous- 14rz in positionV againststops 207 at the end 152e of thebed 12a.

The tail-stock 16a is also reciprocally mounted on theways 20a and 21a by a pair ofgrooves 29a and may be locked in position on thebed 12a by alocking mechanism 38@ having a hand wheel 46a affixed to ashaft 208 to which aneccentric member 210 is ail'ixed for rotation thereby (FIGURE 18). The eccentric 210 carrier aspider 212 having dependingarms 214 which are engageable with theways 20a and 21a to lock the tail-stock 16a in position on thebed 12a. The tail-stock 16a also is provided with anaperture 50a which is adapted to rotat- 66b. The lathe drive 80 ofthe FIGURE 1embodiment 88 when the tool 10a is to be used as a lathe. Also, a pair oflive centers 64a may be used to connect awork piece 68a in position on the tool 10a. Thelive centers 64a are connected to theWork piece 68a by gouging holes in the ends thereof and inserting the uted ends 66a therein. Onelive center 64a is then placed in position on thelathe drive 80 whereupon the tail-stock 16a may be slid toward the head-stock 14a until the otherlive center 64a. engages the tail-stock aperture 50a. Thelocking mechanism 38a may then be actuated to lock the tail-stock 16a in position and a template 11251. may be mounted in a slot 114e onway 21a. The bulbous end 48a of the said one center 74a engages theaperture 78 with a friction lit for rotation by thedrive 80. The bulbous end 48a of theother center 64a on the other hand, is rotatably mounted inaperture 50a and compensates for misalignment of thework piece 68a.

The tool 10a also includes ahandle 96a having a rst end 102er which is provided with an extrusion 10061. The member e may be slidably and rockably attached to thebed 12a by engaging it in aslot 216 provided in theway 20a. Thehandle 96a also includes anend 106a to which atool bit holder 104a is alixed by abolt 218. A llathe tool-'bit 108 of the FIGURE 1 embodiment is secured in position on the tool holder 104:1 by a thumb screw e and `aprobe 120a is attached to the end 10211 by ascrew 220 for engagement with the template 112er.

The tool 10a may be converted from the lathe shown in FIGURE 13 to the bench sander shown in FIGURE 6 by removing the tail-stock 16a frombed 12a and ataching it to the head-stock 14a. For this purpose, the ail-stock 16a includes a dependingflange 222 having a J-shapedopening 224 provided therein which is adapted o straddle theshaft 88. The tail-stock 16a also includes t dependinglip portion 226 which is engageable behind inupstanding flange 228 provided on the head-stock 14a. With the tail-stock 16a in position as shown in FIGURE 16, the device a imay be employed as a bench sander by connecting thelathe drive 80 to themotor shaft 88 in such a manner that theface plate 82 extends through aslot 154a which is provided in the tail stock 16a. Of course, it is .apparent that the circular saw 158 in FIG- URE ll can be substituted for thelathe drive 80 and that the front wall 16C of tail-stock 16a and the top wall 14C of the head-stock 14a cooperate to form a table for supporting a suitable work piece.

, The tool 10a may be converted to a jig saw as shown in FIGURE 17 by engaging aslot 230, which is provided in thehousing 200 of head-stock 14a, with the extrusion 100a provided on thehandle 96a. Thehandle 96a then forms a jig saw fra-me wherein the tool holder 10411 extends above the head-stock 14a in such a manner that theleaf spring 192 previously described in connection with thetool 10 Imay be secured to the tool holder lll-4a by the thumb screw l10n. Thebifurcated end 190 of thespring 192 then extends above anotch 232 which is provided in the tail-stock 16a (FIGURE 19). The head-stock 14a is also provided with a reciprocating plate 16th: which is reciprocated by an eccentric 168:1 axed to theshaft 88 of head-stock 14a for rotation thereby. The plate 169er also includes ablock 178a to which theend 182 of thejig saw blade 184 may be attached for reciprocation by the plate 160a upon rotation of the eccentric 168er.

The probe 121m may als'o be used as a guide fence for jig saw or table saw operation by engaging the tail-stock 16a with a l-ug 120b provided onprobe 120a and securing theprobe 120a in position across the top of tail-stock 16a by tightening thebolt 220.

Referring to FIGURE 20, the tool 10a may be used as a drill press by sliding the tail-stock 16a to the end 152b of thebed 12a and securely locking it in position by actuating the wheel 46a `after which the tool 10a is brought to a vertical position where it is supported bylegs 234 provided on tail-stock 16a. Theaperture 50a `provided in tail-stock 16a received thedrill bit 134 whi-ch is connected to theshaft 88 in the same manner as that employed in connection with thetool 10. Asuitable work piece 136a may then be placed on the wall 16e of tail stock 16a whereupon the head-stock 14a can be lowered toward theWork piece 136a by pushing on thehandle 96a which is connected to the head-stock 14a as shown in FIGURE 17. Upon completion of a drilling operation on thework piece 136a, theheadstock 14a is readily returned to theend 152a` of thebed 12a with a minimum of effort because of the assistance of the spring 30a which also prevents the head-stock 14a from falling when the tool 10a is in its upright position.
