T0 aZZ whom it may concern: v 0

Be it known that I, JnssnA. B. SMrrH,\

a citizen of the United States, residing in Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to collating devices,

or devices for effecting proper relative positioning of a plurality of work-sheets, and is in the nature of an improvement on my co-pending application, SerialNo. 375,676,

" filed April 22, 1920. l5

The mechanism disclosed in said co-pending application is designed for work in which typewritten impressions of names and addresses, or other entries, are made close together on a record-sheet, and at greater distances apart on a form or bill-strip, one address or entry being placed on each bill or form. The said mechanism is so arranged that, in order to obtainthe desiredresult, the record-sheet and the bill-strip areintroduced with the record-sheet on the outside, thus necessitating the use of a record-sheet of lighter weight than usual, in order to obtain a suitable carbon impression on the bill, which is to be forwarded to the customer. Also in that mechanism, the record-sheet,

, during the advance of the bill-strip relative thereto, is held against advance movement by .means located adjacent the front paper table, by which the bill-strip is received from the platen, and the position of the bill strip for different bills is determined by means of a spring-pressed register pin adapted to be projected through perforations in the bill-stripinto a perforation in the front sions, and will, therefore, present a better appearance."

n the embodiment of the lnventlon herein disclosed,-the record-sheet may be held 1920. Serial No. 378,751.

table, and the initial'position of each of the bills may be determined automatically b -.a spring-pressed 1n urged to pass throug a perforation in t e paper table, tooo-operate' .with the bill-strip on the opposite side, suitable means being provided to engage the billstr p on its outer side, and enable the billstrlp to restrain the spring-pressed pin'until the perforation in'the bill-strip is advanced to a position to receive the pin.

' Provision may also be made of a handle, and of suitable connections to enable the record-sheet controlling devices associated with the rear paper table, and the springpressed pin associated with the forward .paper table, to be rendered efiective or ineffective concomitantly. a.

When. the record-sheet is held at the rear paper table, and the bill-strip drawn-forward, the frictional engagement between the bill-strip and the record-sheet will tend to draw the latter forward, and maintain it in proper position on the platen, Whereas, in case the record-sheet is, held by devices ad- 'jacent the front paper table, the bill-stri will tend to draw the record-sheet forwar and cause a bulge between the platen and the holding devices;

Other features and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a perspective view'of a platen frame of an Underwood standard typewriting machine, with my invention applied thereto, parts being broken away to show the underlying structure. v

Figure 2 is a front view of the structure shown in Figure 1. Figure 3 is a side view, partly in section, showing the parts in normal position, with the record-sheet and form-strip positioned by means of the respective leading-edge gages.

Figure 4 is a detail of the parts shown in 1 Figure 3, the spring-pressed pin being restrained by means of the bill-strip.

Figure 5 is a view similar-to Figure 3, but with the parts .shown in position to clamp the record-sheet against the rear paper table, and with the bill-strip advanced sufliciently to bring a perforation therein into register with the perforation in the paper table, thereby permitting the register P111 to project therethrough.

The revoluble platen 1 is supported by means of an axle 2 in end walls 3 of a platen frame 4 of the usual Underwood type, and may be turned either by finger-wheels 5,01' by means of a line-space lever 6 acting through a slide 7 and a pawl 7* to actuate a ratchet wheel 8 fixed on said axle 2. The line-space mechanism may be substantially the same as that disclosed in the patent to Frederick A. Hart, No. 1,281,160, dated October 8, 1918.

In use a record sheet 9 and a bill stri 10, consisting of a series of detachable bil s of the same length, are passed over a rear paper-table 11 and'between the platen and rear feed-rolls 12 and front feed-rolls 13, which may be released during such insertion, the record sheet being placed next to the platen. The leading edge of the record sheet may be gaged by means of arms 14 and 15 having aligned edges with which the leading edge of the record sheet may be brought into coincidence, and the position of the record sheet transversely of the machine may be determined by a side edge gage 16 adjustably secured to one of said arms, preferably 15, b means of a screw 17 extending through a s ot in said arm 15.

The bill strip 10 may be led from the platen upon a paper-table 18, and its leading edge brought into coincidence with a leading-edge gage 19 preferably formed in the paper-tab e itself, the bill strip. being positioned transversely of' the machine by means of a side edge gage 20. Said papertable 18 may be supported by means of a bar 21 to which it may be secured by means of screws 22, the bar 21 being supported by brackets 23 provided with flanges or plates 24, which may be connected with the platen frame by means of screws 25. The release of the feed-rolls may be effected by means of a feed-roll release lever 26 acting through mechanism similar to that disclosed in said patent to Hart No. 1,281,160. i

The feed-rolls 12 and 13 may be restored to normal position by means of the feed-rollrelease lever 26, and a name and address or other entry then printed by means of typebars 27 through a ribbon, not shown, on the bill strip 10, and a carbon copy made on the record sheet 9 by means of an interleaved carbon 28. The worksheets may be advanced after the writing of each line by means of line-space lever 6,'the last actuation of the latter carrying the recordsheet into position to receive the first line of a new name or address. It will then be necessar to advance the form-strip until the next bi l is properly ositioned to receive a new name and ad ress.

In preparation for such movement of the bill strip, a handle 29 isdrawn forward from the position shown in Figure 3 to the position shown in Figure 5, thereby permitting,

at each'side of the machine, a presser member 30, carried by lever 31,..to be pressed against the reartable 11 by means of a s ring 32, which tends to turn said lever 31 a out its pivot 33, and releasing a pin 34 to the control of a spring 35, which urges the same in a, direction to enter perforations 36 and 37 in thepaper-table 18 and in a finger or arm38 projecting from the side edge ga e 20, so-' as to permit the margin of the bill strip to be inserted between said finger and said paper-table 18. Upon reference to Figures 4 and 5, it will be evident that the pin 34 when released will be restrained by the bill strip as indicated in Figure 4, and that when the bill strip is advanced to the proper extent as determined by a perforation therein, the pin 34 will be permitted to advance to the position indicated in Figure 5.

The feed-rolls 12 and 13 may then be cast off by means ofthe lever 26, and the bill strip 10 grasped by the operative and drawn forward until a perforation in the next form or bill is broug t into register with perforations 36 and 3 thereby permitting the projection of pin 34 through the perforation in said form. It should be understood that during such forward movement of. the bill .strip, the record sheet is gripped between the presser members 30 and the rear papertab1e 11 and held against advance move-. ment. The handle 29 may then be returned to the position shown in Figure 3, thereby withdrawing )resser members 30 from the rear paper-ta 1e '11 by means of links 39, one of which connects said handle 29 with the lever 31, and retracting said pin 34 to the rear of said paper-table 18 by means of an arm 40 fixed on a rock-shaft 41 to which said handle 29 is also fixed, and having a forked end embracing said pin 34, which is provided with a head 42 to enable such retraction by means of arm 40. It will be seen that the link 39 at the right (Figure 2), is connected with rock-shaft 41 by means of an arm 41 fixed on the latter. The work-sheets will be positioned for the printing of another name and address which may be effected after restoration of feed-rolls 12 and 13 to effective position. The operation just described may be repeated as many times as there are forms remaining in the bill strip.

Preferably the pin 34 is supported and guided by a cylindrical casing 43, secured to the back of the paper-table 18, and rovided with an opening in its head in which the pin has a sliding fit. The bore of this cylinder is of sufficient size to receive a collar 44 on pin 34, between which, and the head of the casing the spring 35 is supported on the pin.

It will be seen that springs 32 associated with levers '31 and spring 35 associated with in 34 tend to throw the handle 29 forward rom the position shown in F igure 3, m which it is retained durin the writlng of a name and address. For the purpose of retaining the handle in its rearward position, prbvislon may be made of a leaf spring 4:5 fixed on said handle at one end, and provided at its other end with apin 46 having a rounded head adaptedto operatively engage ina depression 47 in the adj acent bracket 23, the relation-between the head of the pm 46 and the depression 47- being such that the pin will ride out of the depression when the handle 29 is drawn forward.

It should be understood that presser members 30 and pin34 ma be used in connection with the ori inal posltioning of the recordsheet and bi -strip. After casting off feedrolls 12 and 13, the record-sheet 9 and the bill-strip 10 with the carbon-sheet therebetween are introduced between theplaten and the feed-rolls, and the record-sheet and carbon-sh'eet passed beneath the front papertable and a rock-shaft 41, the leading edge of the record-sheet being gaged' by means of arms 14 and 15. Handle 29 may then be drawn forward and the record-sheet gripped tioned by the leading-edge gage 19. Obvi-' ously the leading-edge age 19 maybe dispense d with and the p51 34 used for this purpose.

It will be seen that the arrangement of the parts herein disclosed not only enables a ribbon-impremion to be made on the blll-strlp, but also, inview of the arrangement of the grippin devicesto co-operate with the rear paper-ta 1e, and of the posltionmg of the side edge gage 16, so as to project downwardly from the supporting arms 15, the;

greater part of the mechanism is included between the end walls ofthe platen-frame whereby a very comp-act arrangement of the parts is obtained. I

Although the strip 10 has usually been; referred toherein as. a bill-strip and the entries as names and addresses, it is obvious that the strip may be composed of other forms, and the entries may be other than names and addresses.

Variations may be resorted to within the scope of the invention, and portionsof the improvements may be' used without others. Having thus described my invention, I
