JESSE A. B. SMITH, OF STAMFORD, CONNECTICUT, ASSIGNOR T UNDERWOOD TYPE- WRITER COMPANY, OF NEW ORK, N. Y., A CORPORATION OF DELAWARE TYPEWRITING MACHINE.

Application filed October 2, 1922. Serial No. 591,774.

To all whom it may concern:

Be it known that I, Jmsn A. B. SMITH, a citizen of the United States, residing in Stamford, in the county of Fairfield and 6 State of Connecticut, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to typewriters, and 1 -more particularly to typewriters wherein provision is made for positioning a plural- 1ty of work-sheets in the machine, side by side, independently of each other. A feature of the invention is the provision, II" in combination, of two collating tables above the platen, at the front thereof,-.for-positioning work-sheetsside by side, clamping means co-operating with one of the tables to clamp a sheet, and feed-rollers for co- 9 operating with the platen to feed a sheet on the other collating'tableonly.

Another feature of the invention is the provision, in .combinationy'of two 'se arate 'means' for gaging two work-sheets -1n the 8 machine side by side, means for feeding one of the work-sheets .only, and tally-strip mechanism for feedin a tally-strip around the platen, beneath tie inner margins-of both sheets, in position to receive certain of 30 the items typed. on each of the sheets.

Other features and advantages will hereinafter appear.

In the accompanying drawin Figure 1 is a front elevation of the'platenframe of Dan Underwood standard t ewriter, having the feed-rollers omitte at the right side of the platen and having the improvements of the present invention combined therewith. 40 hFi re 2 is a vertical section taken beyond wardthe left in Figure 1.

. A platen-frame 10 supports a platen-shaft 11 w ich carries a laten 12, and is revolu- 4} ble *by the usual nderwood line-spacing mechanism, not shown, operating throu h a ratchet-wheel 13, or by a knob 14. eed- .rollers 15 of the usual construction are provided to co-operate with-the platen at the 50 .left side thereof to control the paper and are 3 movable to eifectiyeand' ineffective positions by the usual paper-releasehandle' 16 and its connectedtrain of mechanism comprising astn right end of-the platen and looking to-.'

shaft 17, crank-arm 18, link 19, crank-arm 20, cam-shaft 21 and the downwardly-extending tails 22 of the levers 23 which carry the feed-rollers. It will be observed that there are no feed-rollers at the right side of the platen (see Figure 1). A bracket 24 is secured upon the platen-frame 10 and supports collating tables 25 and 26, side b side, above the platen, at the front thereo 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 work-sheets 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 for a shaft 33 having a. crank-handle 34 and a clamping arm 35 fixed upon it. A coil spring 36 is connected to pins 37 and 38 on the clamping arm 35 and one of the ears 32, respectively, the arrangement being such that the spring will cross the center of the shaft 33 when the clamping arm is moved in either the clamping arm in either of "these posi' .tions. 5

Tally-strip mechanism comprising reels,

39 and 40 is provided for feeding a tally-.

41 around the un erlie a portion 0 the collating tables 25 and 26, sothatit will receive impressions of the items typed on these portions of the sheets. ThlS tally platen in a position to strip mechanism is identical with that disclosed in the patent to Hart, No. 1,281,160, and will not,'therefore, be described further. Public utility companies, such as electric lightcompanies, which 0 rate over a large territory and have branc es at different 10- calities, sometimes maintain two different kinds of ledgers, one knownas a location ledger. which always stays at aparticular location, and the other known as a customers each of the sheets on led or which follows the customer as he Y moves 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 headed columns of a location ledger-sheet indicating the date, meter readings, consumption, several items of charge and the total amount of the bill. At thesame time the date and total amount of the bill are entered in date and debit columns at the left of the customers ledgersheet. The machine disclosed is used for doing this work as follows: with the feed- 'rollers thrown off, the location ledger-sheet 42 is inserted at the left side of the platen and adjusted to proper position. The feedrollers are then moved to eflective positions. The customers ledger-sheet 43 is then inserted in the machine at the right side of the platen, where there are no feed-rollers, and adjusted to roper position. The clamp is moved to eff ctive position to hold the customers ledger-sheet, and a single line oi items is written on the sheets. The clamp and feed-rolls are then released, and both ledger-sheets are removed from the machine. The tally-strip lies in position to receive the item of consumption and the various items of charge including the total amount of the bill from the location ledger-sheet, and extends to the right far enough to receive the date and the total amount of the bill from the customers ledger-sheet. The total amount of the bill, therefore, appears on the tally-strip as it has been written on each of the ledger-sheets. The strip is then fed a line-space distance as a final operation. It will be seen that the tally-strip affords a convenient check to ascertain 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 put, as for example The mechanism shown and. described provides for two distinct modes of operation, namely, the rollers 15 may be considered as clamping elements to hold the adjusted sheet 42 during a single-line entry, and the rollers cast 0111' prior to the removal of the sheet from the platen, and the tally-strip lines aced after the sheet has been removed; or

t e rollers may serve as paper-feeding elements to simultaneously feed the work-sheet and the underlying tally-strip in unison, where the nature of the typing requires two or more single-line entries on one of the work-sheets, in which case the sheet and the underlying tally-strip would be line-spaced in unison after each line entry. The sheet adjusted at the ri ht hand of the platen and clam ed to the co lating table would not be until the last entry on the companion t P sheet had been concluded and a debit or a credit total rendered; after which operation, thetotal and any other data would be entered upon the ri 'ht-hand sheet, in a singlelme entry, and th sheets then removed 'from the platen. With this latter method,

it will be noted that three work-sheets are employed at each typing operation, comprising one stationary sheet and two sheets having means for a joint line-feeding movement ing with the platen to feed one of the sheets without afi'eoting the other, and a clamp for co-operating with the collating means to clamp the second sheet.

2. In a typewriting machine, means for guiding a work-sheet by both lateral edges, feeding mechanism for feeding the worksheet, means for guiding a second work-sheet by both lateral edges beside the first work sheet, and forv clamping it in a desired posi-, tion, the feeding mechanism being inoperative to act upon the second work-sheet, and

tally-strip mechanism arranged to feed a tally-sheet beneath the adjacent margins of the work-sheets.

3. In a typewriting machine, means for guiding a Work-sheet by both lateral edges, feeding mechanism for feeding the worksheet, means for guiding a second worksheet by both lateral edges beside the first work-sheet, the feeding mechanism being inoperative to act upon the second worksheet, and tally-strip mechanism arranged to feed a tally-sheet beneath the adjacent margins of the work-sheets.

5. In a typewriting machine, a platen,- means for guidin two sheets, side by side, feed-rollers for c amping only ene of the. sheets against the platen, a clamp for clam ing the other sheet independently of t e platen, and tally-strip mechanism for feeding a tally-strip-beneath a portion of each of the sheets.

6. In a typewriting machine, a platen, means for guiding two sheets, side by side, independently of each other, means for clamping one of the sheets to the platen independently of the other, additional means for clamping said other sheet, and tally- T strip mechanism for feeding a tally-strip beneath a portion of each of the sheets.
