TYPEWR-ITING MACHINE.

Application filed November 10, 1922. Serial No. 599,985.

To all whom it may concern:

Be it known that I, Jesse A. B. SMITH, 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 following is a specification.

This invention relates to typewriting machines, and more particularly to the provision in a typewriting machine of meansfor positioning and feeding a pack of small slipsat one of the upper corners of a comparatively large sheet.

In accordance with a recognized method of hotel accounting, it is customary for a typist at the time of the registration of a guest to type his name and address, the number of the room to which he is assigned, and the datein the upper left-hand corner of a statement-sheet which is kept in duplicate and on a set of small memorandum slips which are distributed among the various de' partments of the hotel.

j An object of this invention is to provide means for relatively positioning the statement-sheets and the slips and for controllingthe movements of the latter during the ation. In addition to typing at the top of the statement-sheets the data mentioned, it is also necessary to type the same or similar information on detachable stubs at the lowerextremities of said sheets, and this is done, according to the present invention, immediatelyafter the typing atthe top of the, statement-sheets and without removing the statement-sheets fromthe machine.

, feature of the invention is the provis- 10min a machine for the purpose set forth,

of a front-insertion guide-sheet of suflicient flexibility to be passed about the platen, but which is stiff enough to press firmly against the lower margin of the pack of memorandum slips and draw theslips rearward into the machine" from the front thereof.

' Another feature of the invention is the provision, in combination, of an aligning plate at the front of the machine, a frontinsertion guide-sheet of the character mentioned above, a gage on the aligning plate for positioning the front-insertion guidesheets relatively to the guide-sheet preparatory to Writ'ng on thestubs at the bottom T c5 of the statement-sheets.

Other features and inafter appear.

In the accompanying drawings,

. Figure '1 is a front, elevation of a part of a typewriter having the present improvements applied thereto.

Figure 2 shows a statement-sheet with advantages will herea pack of the memorandum slips in the relaif tive positions occupied by them during Writing. Y

Figure 3 shows the statement-sheet and memorandum slips positioned with reference to an aligning plate at the front of machine.

Figure 4 is a vertical sectional view taken on the line H of Figure 1, showing the sheets inthe positions to which they are a'd- 'justed by g the aligning plate.

Figure5 1s a v ew similar toFigure 4:, I

showing the sheets in the positions occupied by them during the writing of thefirst line.

The typewriting machine comprises a platen-frame 10, a rotary platen 11 mounted therein, the usualline'spacing mechanism 12 for advancing the platenstep by step to bring successive portions of thework into pos tion to be written upon by types 13, feedrollersl i co-operating with'the platen, and means for releasing the feed-rollers including theusual feedroller releasing handle 15.

A sheet 16 of thin flexible material of substantially the same width as the platen, hereinafter referred to as the front-insertion guide-sheet, or simply as the guide sheet,' passes around the platen from the rear, a'nd has its rear end supported upon the usual papershelf 17. This guide-sheet 16 may be made of paper or other suitable a material having the required characteristics of resilience and flexibility.

Paper-fingers 18 pivoted on a rod 19 me tending across the platen-frame carry rollers 20 which are spring-pressed toward the i platen, for engaging the lateral margins of the guidesheet- 16. The springs 21 for press ing the rollers 20 toward the platen may ad vantageously be made stronger than usual in order to prevent any sidewise slipping of the guide-sheet with relation to them.

A paper-guiding chute 22 for guiding the statement-sheets to the platen is mounted on a rod 23 in the rear of the paper-shelf 17. This chute may conveniently be like that disclosed in the patent to McLaughlin, No 1,209,865, granted December 6, 1916, and need not therefore be described in detail. It will suffice here to say that the chute is pivoted on the rod 23 extending between brackets 24 at opposite sides of the platen-frame 10, and is urged in a clockwise direction, as seen in Figure by a spring 25 whereby its lower extremity is pressed at all times into engagement with the guide-sheet 16, and will be effective either alone or in co-operation with the rollers 20 to prevent disarraugement of said guide-shcet during movements of the statement-sheets E26 relatively thereto.

The machine is equipped with a rising sheet presser or guide 27, arranged to participate in the case-shitting movements of. the platen-frame, similar to. that disclosed in the patent to Helmond, No. 1,302,161, granted April 29. 1919. This guide is drawn to its lower limit of movement by springs 28 connected to it and to pins 29,, which springs are also eitective to swing it toward the hplaten into pressing engagement therewit An aligning plate 30 is mounted on a rod 31 extending between brackets 32 at the opposite ends of the platen-frame 10 in position to receive the statementsheets 26 at the delivery side of the platen. This aligning plate 30 is provided with an end gage 33 and a left-side gage 34 for gaging the ends and left edges, respectively, of the statement-sheets 26 and the memorandum slips 35, and with a right-side guide 36 for guiding the statement-sheets. The aligning plate 30 is also. provided with end gages 37 at its opposite sides and outside the side gages 34 and 36 for engaging the leading edge of the front-insertion guide-sheet 16 which is wider than the statement-sheets, to position it rela tively to the statement-sheets 26 and memorandum slips 35 with its leading edge slight ly above the lower edges of the memorandum slips. The upper left-hand corner of the aligning plate 30 is cut away, as indicated at 30", to permit the slips and statement sheets to be gripped by the operator in positioning them.

The machine is used for doing the work described in the following manner. The fced rollers 14 are released the front-insert on guide-sheet 16 is positioned with its leading edge in engagement with the gages 37 on the aligning plate 30; the statementsheets 26 guided by the chute 22 are passed around the platen 11 from the back between the platen and the guidosheet; and their leading edges are brought into engagement with theend gage 33 on the aligning plate. The pack of memorandum slips 35 is then positioned by means of the gages 33 and 34 on the aligning plate, to overlie the state- 1ncnt-sheets, with its lower margin beneath the upper margin of the tront-insertirm guide-sheet 1t and with its upper and lefthand edges coinciding with the corres 'ionding edges of the statement-sheets. The feedrollers 14 are then thrown on and the platen is turned larchward by a knob 38 to feed the statement-sheets and the pack of slips down to the first printing line, the guide-sheet 1!; being also fed by the platen at the same time. The guide 27 co-opcrates with the rollers 20 to press the front-insertion guideshect 16 toward the platen during this movement and thus cause its upper margin to press firmly against the lower margin of the pack of slips. The required data is then typed on the slips and statement-sheets, the platen being lincspaced between lines in the usual way. After the sli )s have been typed. they may be removed mm the machine, but it is still necessary to type the name and address of the guest, his roomnnmber and the date on detachable stubs 3!) at the bottom of the statement-sheets 26.

In order to do this. the feed-rollers 1; are again released to enable the statement-sheets to be drawn forward without disturbing the guide-sheet 16. The lower extremity of the chute :22, pressing against the guidosheet 16, prevents shifting thereof during this adjustment. In typing the particular forms for which the machine is designed, the leading edge of the guide-sheet 16 will be located a sufiicient. distance below the writing position at this stage to permit the first line of writ ing on the stubs 39 to be brought directly to, and exposed for typing in. said position and to permit a subsequent line-spacing movement oil. the ilatcn at typing of the detach able stubs, the guide-sheet being advanced meanwhile, without bringing the guide-sheet to the writing position. If the guide-shect is not so positioned, the statementsheets 26 will be drawn forward by the operator sufficiently far to bring the second writing line into view, and the statementshects and guide-sheet will then be turned back in unison by the platen and the feed-rollers 14 to correctly locate the first writing line in writ ing position. \Vith the feed-rollers on, the statement-sheets may be fed after the typing of the first line on the stubs to the second writing line thereof. All of the data is written on two lines of the stubs. After the writing of the second line, therefore, the statement-sheets may be removed from the machine and the guide-sheet may be reposheet and the short slip in the machine; in

combination, a revoluble platen, an aligning plate above the platen, at the front thereof,

a leading-edge gage on the aligning plate for gaging the short slip and the long worksheet by their leading edges to collate them, a flexible sheet in the machine, outside the long work-sheet. forming a feeding gripper and front-insertion guide for the short slip,
