WRITER COMPANY, 'OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.

TYPEWRITING MACHINE.

Application filed September 30, 1922. Serial, No. 591,456.

To all whom it may concern:

Be it known that I, Jesse A. B. SMITIEI, 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 vfollowing is a specification.

This invention relates to typewriters, and more particularly to typewriters wherein provision is made for positioning a plurality of work-sheets in the machine, side by side, independently of each other. a

A feature of the invention is the provision of two collating tables above the platen at the front thereof for positioning worksheets, side by side, with clamping means on one of the collating tables for holding a sheet in position upon it while the feedsheet to be properly positioned in the machine.

Another feature of the invention is the provision of separate means for guiding two work-sheets through the machine, side by side, in combination with tally-strip mechanism for feeding'the tally-strip around the platen beneath the inner margins of both sheets to receive certain of the items typed on each of the sheets.

Other features and advantages will hereinafter appear In the accompanying drawings,

Figure 1 is a. front elevation of the platenframe of an Underwood standard typewriter having the improvements of the present invention combined therewith.

Figure 2 is a vertical section taken beyond the rightend of the platen and looking toward the left in Figure 1.

A platen-frame 10 supports a platen-shaft 11 which carries a platen 12, .andris revoluble by the usual line-spacing mechanism, not shown, operating through a ratchet wheel 13,101 by a knob 14. The usual feedrollers 15 co-operate with the platen to control the paper and are movable to effective and ineffective positions by the usual paperrelease handle 16 and its connected train of 50 mechanism comprising a shaft 17, crankarm 18, link 19, crank-arm 20, cam-shaft 21 and the downwardly-extending tails 22 of the levers 23 which carry the feed-rollers. A bracket 24 is secured upon the platenframe 10 and supports collating tables 25 rollers are thrown off to permit the other and 26, side by side, above the platen at the Q front thereof. The table 25 has lateral edge gages 27 and 28, and the table 26 has lateral edge gages 29 and 30 for assisting in positioning the worksheets in the machine. A

plate 31 fixed upon the outer face of the edge gage 27 has outwardly-bent ears 32 with holes therein which serve as bearings shaft 33 when the clamping arm is moved in either direction between effective and ineffective positions, and will therefore serve to hold the clamping arm in either of these positions.

39and 40 is provided for feeding a tallystrip 41 around the platen in a position to underlie a portion of each of the sheets on the collating tables 25 and 26, so that it will receive impressions of the items: typed on.

these portions of the sheets. This tally-strip mechanism isidentical with that disclosed in the patent to Hart, No. 1,281,160, and

will not, therefore, be described further. 1

Public utility companies, such as electric light companies, which operate over a large territory and have branches at different localities, sometimes maintain two different kinds of lodgers, one known as a location ledger which always stays at a particular location, and the other known as a customers ledger which follows the customer as hemoves from ,place to place in the territory served by the company. At the time a'bill is rendered .to a customer, entries are made in appropriately headedcolumns of a location ledger-sheet indicating the date, meter readings, consumption, several items of charge and the total amount of the bill. At the same time the date and total amount of the bill are entered in date Tally-strip mechanism) comprising reels and debit columns at the left of the cusand clamped against the collating table 25.

'The customers ledger-sheet 43 is then inserted at the right end of the platen and adjnsted to the line of writing. The feedlateral edges of each table provided with rollers are then moved to effective position, the clamp is Withdrawn, a single line of items is typed including the items above enumerated on the location ledger-sheet, and the date and total amount of the bill on the customers ledger-sheet, and the work is removed from the machine by the turning of the platen through a knob 14: in the usual way or the feed-rollers may be cast off and both sheets drawn out at the front of the platen. The tally-strip lies in position to re ceive the item of consumption and the various items of charge including the total amount of the bill from the location ledgersheet, and extends to the right far enough to receive the date and the total amount of the bill from the customers ledger-sheet, and is usually line-spaced after the single line entry is completed on both sheets. The total amount of the bill, therefore, appears 011 the tally-strip as it has been written on each of the ledger-sheets. It will be seen that the tally-strip affords a convenient check to as certain whether or not the same amount has been written upon the two ledger-sheets after they have been separated.

The above example should, of course, be regarded merely as illustrative of the use of the invention, and not as defining the scope of the use to which the invention may be ut. p It will be seen that the collating tables 25 and 26. with their turned-up edges 27,28 and 29, 30, respectively, comprise a pair of paper gages; that the width between the two turned-up edges is approximately the width of a worksheet; that by laying the worksheets within the gages, each sheet squares itself relative to the platen and relieves the, operator of that much responsibility; that the operator is only required to raise or.

lower the sheet within its gage: as a final; adjustment to align the last printed entry thereon to the wing-scales for a line-spacing position; that the feed-rollers are grouped into two series, one series for each, worksheet; that both series of rollers are released or set in unison by a single key-lever; and that the turning of the finger-wheels will run out both worl-sheets in unison, over the stationary tally-strlp after the typing operation.

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, means for positively positioning individually a pair of related work-sheets side by side in non-overlapping relation, said means com prising collating tables arranged side by side and independent of each other and above the platen at the front thereof, the
