' Application filed February 23,3221; Serial 1 l'0.'538,5 47.

State of Iowa, have" invented certain new and useful Improvements in Typewriting Machines, of which the following isa specification.

This invention relates to sheet-collating means for typewriting machines, and'is similar in its general nature and purpose to the 538,211,filed February 21, 1922. I

'An object of the invention is to facilitate the quick insertion and removal of billsheets from themachine relatively to a record-sheet which is'left in the machine. 1

In carrying out. the invention, there is provided means forholding the record-sheet against the platen'so as not todisturb the position of said record-sheet when the feedrolls are released prior to the removal ofa finished bill-sheet and the insertion of anew bill-sheet. may comprise a clamp element extending into the throat formed by the platen and theregular paper-table over which the billsheets are fed; said clamp element being 0pinvention disclosed. in Inv application No.

erable during the initial part of the move' 30 ment of the feedroll release handle, ajfurther movement of said handle being effective to cast oif the feed-rolls. A collating table is provided at the front of theplaten to adjust a new bill-sheet relatively to the recr ord-sheet after thelatter has been clamped to the platen.

To keep the throat behind the platen open so as to permitfree insertion of a new bill sheet without interfering with the recordslieet, there is provided an auxiliary'rear paper table, above the usual rear paper table or shelf, which keeps the rear end of the record-sheet from falling against the regular paper-table.

Extending this auxiliary paper-table forward aroundthe platen makes it possible to clamp a record-sheet in writing position for the insertion of'one of the short bill-sheets, even when the line of writing is near the bottom of the record-sheet. The auxiliary paper-table also serves to guide the bill-sheets to the outside of the record-sheet in the" lower writing positions'of the recordsheet, by keepmg the record and bill sheets separated up to a point near the'line of writing,

The record-sheet holding means wheel "18 and finger-wheels 19 by which it sdthat "therejis no danger offthe leading edge ofthe bill-sheet catching upon the rear edge of therecord-sheet. i

The invention is in the nature of an {attachment which may readilybe applied to any Underwood standardtypewriting ma chinewithout altering said machine- It will be understood, however, that the invention is .not limited to Underwood typewritin'g machines. o q r I Other features and advantages will here-' inafter appear. I jfli- In the accompanying drawings,, p

Figure 1 is a front elevation of the carriage and shows the invention applied thereto. I f i i Figure 2 is a sectional side elevation taken substantially on the line 2-1-2 of Figured; showing the parts in their normal positions.

Figure 3 is aside view, similar to Figure 2, showing the record-sheet clamp operated.

before the feed-rolls are'released. A Figure 4 isaview similar to Figure 3 and shows .the feed-roll release handle 'fully depressed to release the feed-rolls. I

The platen 10 of an Underwood standard 1 typewriting machine, against which type 1 mounted by means of a shaft 17 supported in thei'end plates of the platen-frame 12, and'is provided with the regular'linespace may be rotated to feed the work-sheets, in-

cluding an inner or record-slieet 20 and an outer or bill-sheet'21 with an interleaved carbon 22, around the platen. ,To'assist in feeding the work-sheets aroundthe platen, feed-rolls 23 may be provided which are supported on bell-crank elements 24 pivotally mounted on the rod 16 'andwhich may be released through the medium of a rock-shaft or feed-roll release shaft 25, said rock-shaft 100 being. provided with cams 26 to engage arms 27 ofthe bellcrank members 24 to release the feed-rolls 23., vThe rock-shaft may be operated by a release handle or lever 28,

which may be depressed to rock a stub shaft I105 28' supported on the end plate HI and a bracket 29. The jstublshaft 28 is p'rovided I with anarm 30 to. pull upwardly a link 31.1
