Patented May 17, 1921.

Application filed July 8, 1919, Serial No. 309,435. Renewed October 13, 1920. Serial No. 418,?49.

To all 107mm it may concern:

Be it known that I, Jnssn A. B. S ITH, a citizen of the United States, residing in Stamford, in the county of Fairficld and State of Connecticut, have invented certain new and useful Improvements in Typewrit ing-Machines, of-which the following is a specification.

This invention relates to the paper-carrying devices of typewriting machines, particularly those having round platens and of the objects of the invention i to improve the means for typing entries upon electric light-bills, gas-bills and the like, and particularly. to facilitate the insertion and removal of the'bills and the making of carbon copies thereof. l

Heretofore the use of typewriters for making outbills of this character has not been found altogether satisfactory because another thereon, andthis has made it necessary for the bill to be carried around the platen by the usual feed-rolls which are run thereon, thus entailing considerable labor and attention in placing the bill under control of the feed-rolls, and'subsequently releasing it therefrom.

In order to overcome these difficulties, I have contrived to introduce the bill into the machine andlocate it at the typing position by a simple operatiomand' provide simple means for producing carbon copies of a succession of bills upon a single record-sheet, and in this way have made it feasible to type bills of this character much more rapidly than heretofore found practicable, and so rapidly that-the typewriter may successfully displace the pen in preparing these bills.

At the'front of the platen, I place an insertion-plate for locating the bill, which is not introduced at the back of the platen as heretofore, but is inserted at the front therealso inserted.

. crosswise of the bill, and the operator also slides the bill up until its top edge slips under yielding clip against a gage provided at the top of the insertlon-plate. The bill is now ready to type inasmuch as said gage is in such position that the bill is in correct typing position, considered from top to bottom thereof. A left-hand gage for-the bill may also be provided upon said insertionplate, so that the operator needs only toslip in the bill at the front, and then slide it along the plate so far as it will go to the left and the top.

Other features and advantageswill hereinafter appear.

In the accompanying drawings,

Figure l is a perspective view of an Underwood typewriting machine, showing my invention as applied thereto.

Fig. 2 is a sectional side view of the same, showing the parts with record-sheet being inserted. t

Fig. 3 is a similar view, showing the bill.

Fig. l is a perspective view of the alining plate.

Fig. 5 nections between the handle for swinging the alining plate and the handle itself.

Fig. 6 is a face view of a bill-head.

Fig. 7 is a diagrammatic perspective of a bill-head and a record-sheet and the intervening carbon-sheet when in writing position upon the platen. v A record-sheet l0 and carbon-sheet 11 are usually inserted simultaneously by passing them down, from the rear, over the usual papentaole l2 and beneath the platen 13, so that hey come up in front of the platen past the wings-sales 14.- at the-printing line, and are bent rearwardly by the paper-fingers 15, which are slidably and resiliently mounted as usual upon the cross-bar 16. In being thus inserted, the record-sheet 10 and carbon-sheet 11 are passed behind an alining and retaining plate or board 17, which stands at the front of the platen above the printing line, and'which is adapted to be is dissected perspective of the con-' swung away from the platen, by rotating the shaft 18, to which it is fast, a will be described below. This swinging out of the plate 17 is done at this time because the record-sheet is only held by the paper-fingers 15 at substantially its outer margins, with the result that it tends to belly up in the center and catch on the lower edge of the plate 17.

Beit'ore inserting the carbon-sheet 11 and record-sheet 10, the usual front and rear teed- rolls 19 and 20 may be cast off (if desired) by depressing the usual finger-piece 21 to the position shown in Fig. 2, said finger-piece being effective through the usual link 22, which is adapted to turn the cast of'f shaft 22. After the recordsheet 10 and carbon-sheet 11 have been carried upwardly, until their leading edges are above and behind the lower edge 24 of the plate 17, the latter is swung backwardly to its normal position, in which it stands advantageously very close to the platen, but yet is clear of the platen, so that the recordsheet and carbon-sheet move readily if the platen is rotated after the feed-rolls are restored, as diagrammatically illustrated in Fig. 3. l

W hen the parts are in the Fig. 3 position, a bill-head 25 may be inserted downwardly in front of the platen by first carrying its lower edge below the wing-scales 1 1, which serve to guide .it clear of the ribbon (not shown), and then the bill-head is slid upi I wardly upon. the alining plate 17, so that its upper end catches under fingers or retaining clips 26, which may be in the form of spring fingers soldered to the back oi the plate 17, and curving over in front of it. There are bends 27 at theupper end, serving as leading-edge gages for the inserted bill-head 25. There may be one of the clips 26 near each end of the plate 17, which may be of substantially the width of the bill-head 25. To facilitate the insertion of the bill-head, one end of the plate 17 (herein shown as the right-hand end) may be left open, so that the bill-head may he slid in from the right under the fingers 26 and alined against a turned-up'edge 28 at the left-hand edge ot the alining plate which serves as a side gage for the bill-head; The bill-heads, especially adapted to be used in this manner, are of the kind for use by public utility companies which comprise only asingle entry. They are provided with a relatively large heading which occupies a space 29, the heading and debtors name being often printed wholly or in large part by an addressograph or machine of that type. The bill also comprises a detachable coupon 30, separated by a perforated line 31 from the main part of the bill-head.

The bill-head shown herein is designed so that all the typewritten entries thereon may be entered on a single line near the bottom of the bill, said entries comprising in a column 32 the date of the bill, in column the present reading of the meter, in column 34 the date of the present reading, in column 35, the amount of the previous reading, and, in column 36, the difference between columns 33 and 35, namely, the consumption. The bill also comprises a space or column 37, which shows the total amount due, a column 38, showing the discount, a column 39, showing the total net, less the discount, and a final column which covers the coupon 34 and repeats the net total item of column It will be observed that the bill is adapter to be inserted when the typewriter is at the right-hand end of its travel, in which position the left-hand edge of the bill, compris ing the column may be substantially clear of the usual ribbon mechanism, thus avoiding any accidental entanglement with it. When the bill-head has been inserted in this manner, the appropriate items described above are typed in the various columns. The wing-scales 14L confine the low .r margin of the bill during the typing operation. \Vhen the last entry has been typed, the carriage may be returned to the right by actuating the usual line-space-lever ll), to actuate the line-space-wheel ll, so that the platen is turned the distance of one line-space, thus advancing the record-sheet 10 and carbon sheet 11 at theusual travel of the carriage. This leaves the carriage at its right-hand end, and, as soon as the typed bill-head has been removed, the carriage is in position to insert another bill-head which is adapted to be written upon in the manner. To enable the typed bill-head to be readily removed, the alining plate 17 may comprise a cut-away portion 42 at the top, to permit the finger of the typist to readily seize the typed bill-head and remove it.

To enable the mechanism to be attached to any machine of standard construction, the shaft 18, upon which the alining plate is carried, is shown as journaled in ears which are fast upon a plate or braeke adapted to fit upon the usual cover-plate l5 oi the Underwood sl1iltframe, and held thereto by a thumbscrew 4 5, which is adapted to pass through the usual screwopening 4:6, and be threaded into the usual thread 47. thus replacing the usual screw" which holds the cover-plate 45 on. The shaft 18 is adapted to be rotated by a piece 48, having a flat-sided opening l9 adapted to fit over the flattened end 50 or the shaft 18, and to be held thereto by a screw 51, threaded into an opening 52 in said shaft. V

The shaft 18 is normally held in such a position that the alining plate 17 keeps its toe or lower edge at just clear of the platen. and, for this purpose, the shaft is provided 7 with a kerf 53, into which a rounded key 54 is pressed by means of a spring 55 of a com- 'mon type. There may be a spring of this kind extending between each of the two ears 43 upon each of the brackets 44. To enable the alining plate 17 to be adjustable and 'yieldingly held in place, it is provided with a pair of slots 56,. forming depressions through which screws 5f7 are adapted to be threaded into brackets 58, fast to small brackets 59 slidable uponthe rod or shaft 18. The brackets 59 each comprise apair of ears 60, between which lies a spring 61 adapted to hold a key 62 yieldingly within the kerf 53.

It will be observed that the bill-heads 25 are not line-spaced at all, and that the linespace mechanism is effective independently upon the record-sheet-10 and carbon-sheet 11, thus enabling the record-sheet to be of any desired standard sizesuitable for binding up. In order to properly locate the entries upon the record-sheet 10, there may be provided the usual adjustable side gage 63 upon the paper-table 12. To guide the record-sheet 1O upwardly, as it comes out from under the paper-fingers 15, the paperfingers are provided with deflecting plates 64:, which are adapted to curve the record-' sheet upwardly behind the shaft 18. The record-sheet 10 is usually materially larger than the bill-head 25, and, for convenience in alining the carbon-sheet with it, the carbon-sheet 11 is usually of the same width as the record-sheet.

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: a
