Original application filed September 18, 1920, Serial No. 411,181. Divided and' this application flled To allwkom it ma concern:

Be it known that JEssE A. B. SMITH, a citizen of theUnited 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.

The present. invention relates to collating tables for typewriting machines. More particularly, theinvention relates to tables 011 which sheets may be collated for so-calledfront insertion in front-strike ty ewriting machines; and'topaper' clips or ngers on the table forholding the sheets in adjusted position during the collating operation.

Thev object of the invention is the provision ofa support, for the fingers behind the table, and preferably on the rear face thereof, where the same cannot interfere with,

- the fingers may be extended around the edge of the'table to project into engagement with the front face thereof over the sheet-field. A feature of the invention is 'a mounting, located as above, for the fingers, which permits a plurality of such fingers to be swun simultaneously to and from effective position, over-a bar or flange forming a marginal, or side, gage, for the sheets at the side of the tabla- 4 A further feature of the invention is a shaping of the fin ers, and the formation thereof of spring s set-material, such that, after being thrown simultaneously to effective position and "before-bein simultaneously released, each, 'indepen ently of the other, may be lifted from the table for insertion of a sheet thereunder. 4 This application is a division of my application, Serial No. 411,181, filed September 18,1920 (now Patent No. 1,451,791, granted April 17, 1923).

Other features and advantages will hereinafter appear.

and work-sheets taken on the line fournaled in the'end walls 11 of the platen-carriage by means of'a shaft 12 and is knob 13. On the carriage is also the usual showing rotated by the ordinary paper-table .15 having an apron extension 16, the latter being provided with openings 18 to accommodate the pressure-rolls 19. The printing position at the front of the platen is indicated by a. type-bar 21; wingsoales 22 being shown at either side of the printing positlon. 1 I a A front collating table 30 is mounted in the end walls of the carriage by means of a shaft; 32 passing through depending ears 31 on the table. The table 15 positioned tangentially to the front ontion of the platen. One edge of the ta le is provided g with an aligning bar or flange 35. Bent to I the front face of the table, over the flange 35, are spring-clips 37 which terminate behind the table in upstanding portions 38, rigidly attached by means of screws 41 to a shaft 39 which passes therethrough; the shaft 39 being journaled in brackets 40 fixed to the under side of the tablet Rigidly attached to the shaft 39 is a collar 45, having two notches 46 and 47' in the periphery; thereof, into which notches a detent-spring 49, fixed to the rear or under face of the table at 50, is adapted to.-fit. In the Fi ure 3 position of the paiit's, ;the spring-c ips rest upon the table, and. the detent49, hav- 7 ing its end in the notch. 46, tends to hold..

the clips in this position. The detent 49 being resilient, however, the clips 37 and shaft 39 with the collar 45 thereon,may be rotated, to bring the notch 47 to the detent 49, which latter, by springing. into'the notch 47, holds the shaft 39 and clips 37 in inefleclive position, against unintentional angular displacement.

In operation, the pressure-rolls may be released from the platen in the usual way,"

and the spring-clips thrown to ineffective position. The several work-sheets and carbons may then be adjusted with respect to each other, or collated, on the table, with their lower or rear ends between the pressure-rolls and the platen; the spring-clips being thrown to effective position, temporarily to hold the collated sheets. The collation being completed, the pressure-rolls are reapplied, clamping the sheets in their adjusted position to the platen.- The springclips are then thrown to ineffective position to permit free movement of the collation to the first printing line, by turning the platen in reverse direction, and then to permit linespace feed of the collation in the usual way during the writing. Certain sheets, such, for instance, as the record-sheet, may be fed under and around the platen, over the table 15, in the usual way, to the table 30, before the other sheets are set upon and adjusted with relation to the sheets thus first inserted.

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:

1. In a typewriting machine, a platen, a

i collating table, and a paper-finger ivotally mounted behind the table, extending around the edge of the table, and projecting over the sheet-field at the front of the table, the

finger being movable-on its pivot'into and out of engagement with the front face of the table.

2. In a typewriting machine, a platen, a collating table, a bar or flange on one side of the table to serve as a side gage for the paper, and a paper-finger pivotally mounted behind the table, extending around the edge of the table, over the side gage, and protruding laterally and downwardly over the sheet-field to the front face of the table, the finger being movable on its pivot intoand out of -engagement with the front face of the table.

In a typewriting machine, a platen, a collating table, a rock-shaft j ournaled on the rear of the table and parallel to the side edge thereof, a plurality of paper-fingers fast to the rock-shaft and spaced apart thereon;

'the fingers being bent around the side edge of the table to protrude laterally over the sheet-field into engagement with the front of the table, means for rocking the shaft to throw the paper-fingers into and out of engagement with the table, and means for I holding the shaft against, unintentional rotary movement.

side edge of the table to protrude laterally over the sheet-field into engagement with the front of the table, means for rocking the shaft to throw the paper-fingers into and out of engagement with the table, and a spring-detent engageable in notches in the shaft, to determine the finger-settings there of and to prevent accidental rotary movement of the shaft from such settings.

5. In a typewriting machine, a platen, a collating table, a rock-shaft journaled on the rear of the table and'parallel to the side edge thereof, a pluralityof paper-clips fast to the rock-shaft and spaced apart thereon; the clips being bent around the side edge of the table to protrude laterally over the sheet-field into engagement with the front of the table, and means for rocking the shaft to throw the clips into and out of engagement with the table; the clips being resilient so that the same may be also independently pressed from the table.

,6.

automatically enter, either of the notches,

table and parallel to the side edge thereof,

a plurality of paper-fingers fast to the rockshaft and spaced apart thereon; the fingers being bent around the side edge of the table, and around the side gage, to protrude laterally over the sheet-field into engagement with the front of the table, the shaft being rockable to throw the paper-fingers into and out of engagement with the table, and a yielding detent to hold said fingers against the table or away therefrom.

8.
