TYPEWRITING MACHINE Application filed June 9,

The present invention relates to an improved web or work-sheet cabinet to be used in connection with continuous billin typewritting machines, one form of w ich is shown in the patent to WVernery & Smith, No. 1,132,055, granted March 16, 1915.

In a machine of this type, work-sheets or webs are used in several layers or plies, each provided with printed forms constituting one piece of work, which, when completed, may be torn from the continuous web. Carbon-sheets interleaved between the webs or plies are mounted on a carbon-carriage, so as to advance with the web toward the platen while typewriting, and so as to, be drawn back by the carbon-carriage into the succeeding form-section of the web after the leading formsection has been typed, and prior to detachment from the web of such leading form'section.

To save time and trouble in substituting a work-web of one style for that of another,

the carbon-sheets, as shown in United States Letters Patent to Fortin, No. 1,237,319, granted August'21, 1917 are not directly attached to the carbon-carriage in the machine, but are attached to a plate or holder which is detachably secured to the carbon-carriage so that a carbon-sheet-holding plate for any set of webs, with the carbon-sheets interleaved therewith, may be removed as a unit from the carbon-carriage, and another car bon-sheet-holding plate, with carbon-sheets already interleaved with the plies of the desired set of webs, substituted therefor. Containers or cabinets for the several webs and their respective carbon-sheet-holding plates and interleaved carbon-sheets have heretofore been devised to provide for a feed of the web from its container to the carbon-carriage of the typewriting machine, when thesheet-holder shall have beenplaced on the latter. 1

The present invention has particular reference to an equipment whichcomprises the above-mentioned continuous billing apparatus as applied to a bookkeepingtypewritcommonly present on the rear of bookkeep ing machines. Such other support for the 1922. Serial 110. 566339.

be assured. It will be understood, however.

that the invention is not confined to use in connection witha bookkeeping machine or with a machine-standof any special type.

An object of the invention is the provision of a combined holder or support for the carbon-carrier table, and attachment for a plurality of web-containers, or web-cabinet;

which combined device is supported by the typewritingmachine-stand,independently of i316 machine itself; and along which combined device the web-containers or cabinet is adjustable to permit the particular web which is to be used, to be brought to set position with respect to the carbon-carrier table; w A further object of the invention is the provision of such a'combined device and of a. holder or cabinet for a plurality of web containers connected thereto and adjustable therealong, but supported on the floor, so as to be movable as a unit with the typewriting-machine-stand.

A feature of the invention is the prov'1 sion of a runway on the combined carriertable support and web-cabinet attachment,

along .which runway the cabinet may he other cabinet is desired to be substituted therefor. In the preferred form of the invention. hereinafter described, the cabinet may be positioned ordetached by simply sliding the same on or off of one end of a rail on which the cabinet is adjustable for the setting of any container thereof with respect to the carbon-carrier table.

Other features and advantages will here inafter appear.

In the accompanying drawings,

Figure 1 is a view in side elevation, part-- ly crosssectional, showing an Underwood bookkeepingmachine, with continuous billing attachment and stand therefor, and with the combined work-box cabinet and carboncarrier table-support of the present invention connected to the stand.

Figure 2 is a view in rear elevation of the work-box cabinet and carbon-carrier table-support shown in Figure 1.

Figure 3 is a detail View, in side elevation, of the latch for holding the work-box cabinet in selected position.

The frame of the bookkeeping machine is shown supported on a platform 11 of astand having uprights 12 andcross-braces 13, and having thefeet 14 thereof provided withrollers 15, to permit the stand with the machine and associated parts to be wheeled from place to place.

The platen 16 is revolubly mounted on an axle 17, carried by arms (not shown) forming part of a swinging frame pivoted at 19 to the carriage-frame 20. The normal position of the platen is its full-line, Figure 1 position, but it may be swung up around the axis 19 as a pivot to permit the fan-fold webs to 'be advanced in the usual manner, for

' detachment of the leading written section and for placement of the succeeding section thereof. The usual front andrear pressurerolls 21 and 22 are provided for feeding the web with the platen. The carriage runs on arod 23 carried by the main frame.

Attached to the carriage are brackets 24 for supporting the forward end of the carbon-carrier table 25. The brackets 24 are connected by across-piece 26 having other brackets orcars 27 thereon; and thecars 27 carry thebar 28 which defines the front of the table 25. On the table is. a carbonholder and carrier .29, adapted to move with the carbons (not shown) and with the web 30 toward the platen as the carbons and web have their line-feed movements around the platen, and which is adapted to be moved backward with the carbons, independently of the web, to draw the carbons into a Sun ceeding web-section after the leading websection has passed around the platen. It is unnecessary here to describe in detail the entire construction of the table and associated parts, reference being made to the aforesaid United States Letters Patent to Fortin, No. 1,237,319, for such description thereof as may be desired. Suffice here to say that the carbon-holder of the Fortin patent comprises aplate 31, having secured thereto a number of clips (not shown), each of which clips engages and holds the rear end of a carbon-sheet, the several clips being stepped up, one from another, more conveniently to enter and slide between the superposed web-plies.

In the Fortin patent, a single fan-fold web is shown; the superposed plies forming the web each being compo-ed of detachable units bearing the same individual form or blank. Instead of the single web comprised of fan-folded superposed sheets or strips, several single strips or webs, as here indicated at 32 above the platen and at 33 in the lower work-boxes, may be employed; each of the superposed webs being composed of such detachable units.

"he table 25, near the rear thereof, has a pair of dependingbrackets 34, each of which carries aroller 35 which rides on arail 36, supported onbrackets 37. Thebrackets 37 thus support the rear of the carbon-carrier table, and the latter, by reason of therolls 35 riding on therail 36, is free to have letter-feed and return movements with the umen-carriage of the typewriting machine, to which it is connected at its forward end.

The right andleft hand brackets 37 are connected at the rear byrails 38 and 3 and at the front by abar 39 carried byarms 40 secured by screws 41 to the brackets. Thebar 39 serves as a front support for thebrackets 37 on the platform of the stand 11. and is secured to the platform of the stand byscrews 42. Each of thebrackets 37 has also a frontVertical reach 43, the lower end of which is turned outward laterally, as shown at 44 in Figure 2, and is turned in the shape of a U around the corresponding rear upright 12 of the machine-stand 11. By means ofscrews 45, the U-shapedoffsets 44 of thebrackets 37 are fixed to the up--rights 12 of the machine-stand.

In assembling thebrackets 37 on the stand 11, thebar 39 is first positioned and screwed in place. Thebrackets 37 are then separately brought to position against the outside faces of the arms 40of thebar 39, with theirU-shaped extensions 44 embracing thelegs 12 of the stand. The screws 41 are then applied to secure the brackets to thebar 39. Therear rails 38 and 38 are then set in place and secured byscrews 37* to thebrackets 37. Thereupon the set-screws 45 are tightened to fix the lower front portions of thebrackets 37 to the legs of the stand. The setting of thebar 39 by thescrews 42 determines the proper setting of therail 36, so that the latter may be parallel to the path of movement of the carriage on the machine-frame.

Behind thebrackets 37 is the Web-cabinet. This is shown as comprising six work-boxes 47 arranged in two tiers of three each. The cabinet is formed of three vertically-disposed boards 48, 49 and. 50; three rear-wall boards 53; and three ho "izontal floor-sections of which carries two rollers and 56. i The rollers 55 engage the "rails 38 and 58 at the front thereof, and therollers 56 engage these rails at the rear thereof. The rails38 and 38 therefore serve not only to connect the cabinet to thebrackets 37, but serve also as runways on which the cabinet may he slid to the right or left tobring either the left hand or the righthand tier of work-boxes into position for the feeding of a webtherefrom to the carbon-carrier table. In Figure 2, the cabinet is thrown to the right to bring the left-hand tier of work-boxes into centered position with respect to the carboncarrier table.

For holding the web-cabinet in selected centered position for one or the other tier of work-boxes, a latch is provided. As shown in Figure 3, this latch comprises adog 57 pivoted at 58 to the outer face of the left-hand wall 50 of the cabinet. According to the position of the cabinet, the nose 59 of the 'dog 57 is adapted to enter one or the other of twonotches 60 and 61 in the upper edge of therail 38. Thenotch 60 defines the position of the cabinet for use of webs in the right-hand Figure 2 tier of work-boxes, and the notch61 the position of the cabinet for use of webs in the left'hand Figure 2 tier of workboxes. A leaf-spring 62, hearing on the upper edge of thedog 57, causes the dog automatically to enter one or the other of thenotches 60 and 61 when the cabinet. has been slid to bring the dog into registration with such notch; and holds the dog in the notch against accidental displacement. A finger-piece 63 serves to lift.

the dog from thenotches in the rail against the action of the spring 62. A stop 64 on the end of therail 38 prevents the cabinet from being overthrown or displaced from the rail when moved to the left. The cabinet may, however, be entirely removed from thebrackets 37 by being slid off the righthand ends of therails 38 and 38, Figure 3.

The several multi-ply webs in the different work-boxes in the cabinet may, together with their interleaved carbons and attached carbon-holders, be substituted one for another on the carbon-carrier table, in a manner well understood in the art. In the drawings, the web in use is that which is being fed from the upper left-hand Figure 2 work-box, and the carbon-holder 29 for that web is in place on the carbon-carrier table. The other webs are shown as disconnected from the carbon-carrier'table work-boxes; the carbon-carriers 29 and 29 for such other webs being shown as also in the work-boxes of their respective webs.

The web 30 in use is shown as being fed out of itsbox 47, over arod 65, supported on anextension 65 of the rear end of the table 25; thence forward over the table 25 and over a rod 66, carried by the brackets 24 at the rear of the platen. From the rod 66, the web is led downward, around the platen, and thence upward across a table 67 on the platen-carriage. In order that the webs may feed freely from the lower boxes, the boxes are offset downward andrearward, one from another, in each tier; and the outer ends of the floors of the upper and lower boxes carryrounded rails 68 and 69, over which the webs from the lower boxes may slide without. friction. The boxes have a slight forward dip in order that the webpac-kages may not be accidentally dropped therefrom, either in the feeding of the webs or in the handling of the equipment.

It will be noted that, by reason of the connections of the cabinet to the stand, and by reason of the casters on which the cabinet rides, the stand, with the carbon-carrier table and work-piece cabinet, maybe rolled as a unit from place to place.

It will also be noted that, in supporting the carbon-carrier table on thebrackets 37, instead of on the machine-frame, and in so shaping thebrackets 37 to provide considerable clearance between the same and the machine-frame, ample space is allowed for the attachments (not shown), but usually present on the rear of the bookkeeping machine, and ample provision is made for easy access to such attachments.

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