Specification of Letters Patent.

Patented Aug. 20, 1918.

Application filed .Tune 26, 1916. Serial No. 105,792.

To all Z whom it may concern:

Be it known that I, CURTIS W. SHIELDS, a citizen of the United States, residing in Brooklyn borough, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to means for use with typewriting machines, to facilitate a quick and accurate adjustment of worksheets on the platen in position for being written upon, particularly where such sheets are placed on the machine a number of times, the sheet being adjusted at each new insertion to a difl'erent or more advanced position, corresponding to the increase in the typewritten matter thereon.

The invention is also advantageous for use in work in which a number of the sheets are placed on the machine together in different positions of advancement, and especially where one or more of said sheets are repeatedly placed on the machine, each time in' a different position relatively to other sheets collated therewith, as is customary for example, in some systems of bookkeeping. I

An object of the invention is to provide means, operative upon a work-sheet while the latter is on the machine, to produce an impressionon the sheet which will later serve as a gage in adjusting the sheet on the platen. Such impression may be made at a position corresponding to the advancement of the sheet in line-spacing direction, at the completion of the typewritten matter, before the sheet is removed, so that when the sheet is again placed on the machine to be further written upon, it may be quickly and accurately adjusted by means of said impression,

to a position corresponding to the position of the last ty ewritten line.

More speci cally, the inventionmay comprise a cutting or punching device or devices operable as the work-sheet-is advanced. around the platen,'to shear or punch porby leaving upon the edges of the work-sheet gaging surfaces or shoulders at positions corresponding to the advancement of the sheet, said cutting devices themselves preferably serving as gages, so that the sheet,

after it has been removed from the machine, may again be placed thereon and gaged or brought to the position it occupied before it was last removed. The combined cutting and gaging devices may be located, one at each end of the roller platen and arran ed to be operated by the usual line-spacing mechanism to out or trim off a section of each side margin of the work-sheet at each line-spacing operation. A narrow strip of waste may thus be trimmed off each side margin little by little as the page is written. This operation leaves shoulders or jogs in thesheet at the termination of the trimmedofi' portions. Hence, each sheet has opposite shoulders on its side edges at positions therealong corresponding to the position of the last typewritten line. These shoulders are naturally in engagement with the ends of the punches, and the latter thus form gages en a number of sheets have been placed on the machine and written upon, the under sheet may be allowed to remain in the machine while a fresh top sheet is substituted,

set immediately to position to write the next line thereon. This top sheet may have been partly written before, so that it is provided with alining shoulders or jogs. Said-sheets may also be manufactured. with their upper edges trimmed off to form gaging shoulders which, when adjusted to the punching gages, position the sheet for the first line of writing. I

The sheet-gaging cutters or punches may be arranged to be operated by the usual linespacing lever. The latter has an f initial movement during which the platen remains at rest, while the cutters are swung to cutting. and gaging position, and then released and swungout of the path of the worksheets before the latter are advanced bythe line-spacing mechanism. A key may be provided to silence the cutting and gaging having jogs or shoulders whereby it can be sheets are placed on the platen, they may be drawn forward until arrested by said gages,

in position to be written upon. The feedroll release key may then be returned, thereby causing the feed rolls to clamp the sheet in position on the platen and cause the gaging devices to be withdrawn.

A key may be provided to actuate the cutting gages independently of the line-spacing mechanism and the feed-roll release key.

Other features and advantages will hereinafter appear.

Fig. 11 is a sectional view as indicated by the section line 1111 on Fig. 2.

Arotary platen 12 may be fixed to theplaten axle 13 journaled in theends 14 and 15 of a platen frame. Aninclined papershelf 16 at the introductory side of the platen aavaars may form part of the platen frame. Typebars 17 (Fig. 2) may be operated by the usual mechanism, to cause the types thereon to strike against the front face of the platen. The platen frame and platen may be shiftable to upper and lower-case positions on thecarriage frame 18. The carriage may be mounted on the machine frame for letterfeed travel, the usual mechanism for driving moves rearwardly a slide bar ordriver 22 on which is pivotally mounted adog 23 to engage and drive a line-space ratchet wheel 24 xed to the platen, and thereby rotate the platen. The line-spacing lever and said driver may be returned by aspring 25. The stroke of the line-spacing pawl is regulatable as usual for 1, 2 or 3 spaces by a bandle 20 The work-sheets may be placed on the paper-shelf 16 and. advanced around the under side of the platen, and upwardly over the front -face of the platen to writin'g position, being guided between the platen and aguide plate 26 forming a continuation of theshelf 16.

Platen feed rolls 27 and 28 normally bear upon the under surface of the platen and cooperate therewith to feed the work-sheets asthe platen is rotated. Said feed rolls may be thrown ofi' the platen to permit the worksheets to be adjusted on the platen "or removed while the platen is at rest. For this purpose, a feed-roll release key 29 is pivoted at 30 on the platen frame, and comprises an arm 31 connected througha link 32 to a rock arm 33 on arock shaft 34. The feed rolls are mounted onshafts 35 Sup ported inlevers 36 pivoted on arod 37, saidlevers comprising arms 38 which may be spread by means of flats orcams 39 on therock shaft 34. Thus when the key 29 is depressed to the Fig. 5 position, the feed rolls 27 and 28 are thrown elf the platen and held in such position'until an upward pressure is applied to the key 29 to restore said rolls to narrow strip off each side edge of the work-' I sheets on the platen, the length of each section or cutting being of course equal to a line-space distance, or the distance the worksheet is advanced by an operation of the linespace lever. By this operation shoulders or gagingedges 41 are formed on the margins of the work-sheets, such gaging shoulders thus always having a fixed relation to the last typewritten line on the work-sheet.

Thecutting devices 40 serve as gages to which the gaging edges 41 may be adjusted, so that if a work-sheet .has been written upon by the machine and then removed, the gaging shoulders 41 formed durlng the linespacing operations, provide a means by which the sheets may be quickly and accu-- rately adjusted, when again placed 'on the machine, to a position determined by the position of the last typewritten l1ne upon the sheet.

The cutters or punches 40 are each mounted on arock arm 42, said arms being fixed to arock shaft 43 which may be journaled in the ends of the laten frame. Theshaft 43 ma be rocked y means-hereinafter describe to swing the punches or dies 40 downwardly into die-openings 44 formed in die-plates 45, each of which may be'in the form of a ring mounted on an annular flange orprojection 46 formed on a supportingplate 14 attached to the adjacent platen frame end and projecting inwardly from said plate toward the platen. Therings 45 may be of the same diameter as the platen l2 and concentric therewith, said rings abutting against the ends of the platen and forming a supportin surface or backing for the margins of t e work-sheets which project beyond the end of the platen. Eachring 45 may be secured to its supportingannular flange 46 by clampingscrews 47, which extend freely through openings 48- in thering 45 and are threaded into theflange 46. Theopenings 48 may be elongated to permit rotative adjustment of the said ring to accurately register the die-opening 44 with thecutter 40.

The mechanism through which the linespace lever is operative to actuate the cut-- ters, will now be described. Theforward end 49 of theslide bar 22, which is bent inwardly to extend perpendicular to the body of said bar, thereby providing a shoulder against which thearm 21 bears, is utilized to actuate the cutters. For this purpose, an arm 50 (Figs. 2, 4 and 8) connected by apivot 51 to arock arm 52 on theshaft 43, extends forwardly from its pivot, with its forward end supported directly behind theend 49 oftheslide'bar 22 to be actuated thereby. Thecutters 40 are. normally held end of said spring being connected to the platen. This idle or lost motion is utilized to actuate thecutters 40, as it is obviously desirable that thecutting or punching op-. eration should be effected and the cutters withdrawnfrom the path of the work-sheet while the platen is still at rest.

As shown in Fig. 2, theend 49 of theslide bar 22 is directly in front of the forward end of thearm 50, so that as said slide bar moves rearwardly from its startingposition 49, Fig. 4, to the full-line position,

thearm 50 is also moved rearwardly and operates through the arm 52'to rock the shaft 43' and swing the cutters inwardly,

thereby cutting a section of]? each side margin of the work-sheet. The parts are so timed that thecutters 40 have completed their operative stroke by the time thelinespa'cing pawl 23 has been brought to position to drive the ratchet wheel. In order to release thearm 50 from thedriver 49 at or before'this time, saidarm 50 is provided with a forwardly and upwardlv inclined cam surface 55 beneath apin 56 on the platen frame. As thearm 50 is moved rearwardly, it is at the same time cammed downwardly by said pin, and as it reaches the Fig. 4 position is disengaged from thedriver 49, permitting the latter to continue its forward movement to the 49 position, thereby line-spacing the platen, while, thearm 50 being released, thespring 53 throws the cutters back to starting position. VVhen thedriver 49 is returned to its initial positlon 49 (Fig. 4), thearm 50 is thrown upwardly to the Fig. 2 position, by means of a leaf-spring 57. Saidspring 57 is connected wlth a swingin arm or latch 58, connected by apivot 59 wlth thearm 50. Saidarm 50 is held with a yielding pressure against thepin 56 by means of thespring 57, the forward end of which is supported on apin 60 in thearm 50.

The operation of thecutting device, in conjunction with the line-spacing operation, may be briefly reviewed as follows: lVhen the line-space lever is operated, the movement of the driver thereby from the startingposition 49" (Fig. 4) to the full-line position (Fig. 4), swings thecutters 40 111- wardly, causing each cutter to sever from the margin of the work-sheet a strip equal in length to a line-space distance. As thedriver 49. reaches the full-line position (Fig.

4), thearm 50 is carried below the driver, the cutters are snapped upwardly by thespring 53 out of the path of the work-sheet, and the driver, as it continues its forward movement, rotates the platen, line-spaces the work-sheets, and brings a new portion of the margins below the cutters. Thering 45 andflange 46 may be provided with anopening 61, through Which the punchings may fall.

The cutting gages 40 may be operated independently of the line-spacing mechanism by means of a key 62 fixed to therock shaft 43. When it is desired to operate the linespacing mechanism, without operating the cutting gages, a key 63 is depressed to silence the gages. This key (Figs. 2 and 10) is povoted at 64 on the platen frame, and comprises a dependingarm 65 provided at its lower end with aninclined cam face 66, which, as the key is depressed, is swung forward and strikes a.pin 67 on thearm 50, thereby swinging said arm downwardly to the Fig. 10 position, in which it is held below thedriver 49, so that the line-space lever may be operated without affecting the cutting gages. When the key 63 is fully depressed, thecam surface 66 is carried beyond thepin 67, so that the latter bears against a dwell surface 68. The key 63 is held in either its depressed position or its normal inoperative position by a spring detent arm 69, having a detent to seat in notches 70 in the platen frame.

Thegages 40 may also be actuated by the platen-feed-roll release key 29. To this end,

the arm 31 (Fig. 9) of the release key lever has fixed thereto anextension 71, provided with a cam surface 72, which, when the key 29 is depressed, strikes apin 73 on arock arm 74 on theshaft 43, and rocks said shaft to swing the cutters to the Fi 5 position. Thepin 73 now rests against awell surface 75, thereby holding thegages 40 in operative position until the key 29 is returned. It will be seen, by reference to Fig. 9, that the key 29 is depressed sufiiciently to throw the feed rolls off the platen before the gages are operated. In other words, the feed rolls may be moved to and from the'platen without operating the gages. Each cutter comprises a longitudinal cutting edge 76 (Fig. 9) and a transverse cutting edge 77 (see also Fig. 11). The latter edge at each out forms the gaging edge orshoulder 41 on the work-sheet. The cutting edges 76 and 7 7 are preferably both inclined so as to produce a shearing cut. The outer end face 78 of the cutter block is preferably curved in an arc concentric with thepivot shaft 43, and, when the cutters are swung inwardly, provides a gage or abutment to which the sheets may be gaged, as hereinafter pointed out.Guide plates 79 may be located below thegages 40 and extend within a short distance of the gates, said guide aaraaae plate being spaced from thering 45 to pro vide a guideway for the margins of the worksheets. Said guide plates serve to hold the sheets close to thering 45 at the gages, thus securing accuracy and uniformity of the gaging operations.

Fig. 6 indicates a method of arranging and gaging a number of the work-sheets on the platen prior to typewriting thereon. These sheets a, b and c may all be placed on the platenat the same time, and then individually adjusted and gaged on the platen by bringing the gaging shoulders 41 on the sheets up to thegages 40. That is, after the sheets have been placed on the platen, the innermost sheet a, for example, may be grasped at its leading edge (either at the middle or at one or both corners) and drawn upwardly until theshoulders 41 thereof are brought up to thegages 40. The sheets I) and 0 may in turn be gaged in like manner. The sheets are thus collated and gaged so that each sheet is in proper position for receiving typewritten matter directly below the last line typewritten thereon before the sheet was removed from the machine at a preceding operation. It will be understood thatcarbon sheets 80 are interposed between the several work-sheets a, b and c, and are narrower than the work-sheets, so that they are not affected by the cutters.

Prior to placing the sheets on the platen as shown in Fig. 6, the feed-roll release key 29 may be depressed to the Fig. 5 position, thereby throwing the feed rolls off the platen, enabling the sheets to be quickly placed on the machine without rotating the platen, thegages 40 by such depression of the key 29 being brought to operative position. When the sheets have been individually adjusted to the gages, as above noted,

the release key 29 is lifted to return the feed rolls and clamp the work-sheets to the platen, and at the same time withdraw the gages to an inoperative position. The llnespace lever is operated after the completlon of each typewritten line, to advance the work-sheets and concomitantly operate the cutters. After the last line has been typewritten, the line-space lever may again be operated before removing the sheets, to bring them to the position they will occupy when again placed on the machlne and adjusted ready to be written upon. The key 29 may then be operated, before wlthdrawing the sheets, to lift the feed rolls and at the same time operate the cutting gages 40, so that when the sheets are again placed on the machine and adjusted to the gages, they are in position to be written upon without operating the line-spacing lever.

The work-sheets, if desired, may be provided with rows ofperforations 81, ermitting marginal strips to be torn ofi', after the typewritten entries on the sheet have been ledgers or the like.

formed to providegaging edges 41 in such I position that when the sheet is placed on the platen and adjusted to bring theedges 41 to thegages 40, the sheet is in proper position to receive the first typewritten matter. Such sheets may be prlnted bill-heads, invoice-sheets or other printed forms, or plain sheets.

The present invention is particularly useful in work wherein a number of sheets are placed together on the machine, with their leading edges at different positions of advancement, as is customary in some systems of bookkeeping and in other Work. Thus, for example, it i customary to place a record sheet, such as b (Fig. 6), together with an overlying or underlying bill or invoice,

I to receive typewritten entries. The record sheet may receive the entries made on a num- .ber of different bills or invoices, so that said record sheet may be placed on the machine many times, and each time in a d fferent position relatively to the accompanying bill or invoice-sheet. The present invention permits all the sheets to be placed on the machine at once and quickly adjusted, to bring the individual sheets, each to a position corresponding to that of the last written line thereon, without requiring the operator to see the typewrittenmatter on the sheet, which may be hidden by an overlying sheet. The work-sheets may be manufactured with gagingshoulders 41 as indicated in Fig. 7, in such position that when the sheet is gaged thereby on the machine, it Wlll be in position to receive the first line of writing. The sheet may have a printed heading, including a date line as shown, which will be positioned at the printing line on the platen when the sheet is gaged by means of said shoulders 41.

Although,-for the purpose of construction, the cutting edges 76 and 77 are on the same block that forms the gage, that is to say, the cutter and gage are formed of'one piece,

yet the function of the cutter is entirely distinct from that of the gage, and said elements do not-need to be formed as a single part in all cases. By curving the surface 78 of the gage concentrically with thepivot shaft 43, as before noted, the gaging surface serves to position the sheets at the precise position they occupied when operated upon by the cutters, although this is not necessary in all cases, nor is it essential that the position to which the sheets will be gagedbe the same as that occupied by the sheets when operated upon by the cutters, nor that the cutters and gage be simultaneously operated.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:
