' TYPEWRITING ISEACHINE.

Specification of Letters Patent.

Patented Aug. 15, 1922.

Application filed December 12, 1918. Serial No. 266,433.

T 0 all whom it may concern Be it known that 1, 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 Typewritlng Machines, of which the following is a specification.

This invention relates to collating devices, and is herein illustrated as applied to an Underwood typewriting machine or an Underwood bookkeeping machine. IVhere such machines are used for highly specialized systems of bookkeeping, means are highly desirable for obtaining practically automatically the proper registry between a ledger sheet and a statement sheet when inserting them vinto the machine.

In some systems, the statement sheet has been provided with an edge separated from the body of the sheet by perforations, to permit a statement sheet to be employed which is originally of the same width as the record or ledger sheet, and yet to enable the statement sheet to be easily severed along the line of perforations, so that it may be readily reduced in size to a convenient form for mailing. In the endeavor to avoid such expedients as that just described, end gages have been devised to enable the statement and ledger sheets to be adjusted separately, but such end gages usually proved awkward in use, inasmuch as the sheets had to be adjusted separately, thus requiring two sets of end gages which were independently operable.

According to the present invention, I have found it possible to avoid the use of separate end gages and yet provide a fixed edge or device to enable the typist to instantly adjust the statement sheet at the proper line; To do this, I employ a front collating table, one form of which is disclosed in the Corell Patent No. 1,262,310, dated April -9, 1918, and attach thereto an aligning edge against which the typist may align the top of a statement sheet by feeling, (i. e., without needing to study it), so that when ad usted the statement sheet and ledger sheet may be easily clamped into position, as by the usual feed-rolls. This aligning edge or plate may be adjustable to permit it. to be set for vanous heights of bill heads or statement-heads and for various widths of suchheads, the latter object advantageously, being accomplished by substituting one aligning edge for another, since the plates on which the edges are formed may be cheaply made. The aligning plate also forms part of a guide to direct the statement sheet back of the ledger sheet.

Other features and advantages will here mafter appear.

In the accompanying drawings,

Figure 1 is a perspective view of an Underwood typewriting or bookkeeping machlne carriage, showlng so much thereof as will effectively illustrate some of the uses of my invention.

F igure 2 is a side view of the same largely in sectlon.

Figure 3 is a diagrammatic front view, showing the relationship of the record or ledger sheet and the statement sheet.

In the carria e of the Underwood typewriting or bookkeeping machine, the platen 1 is rotatably mounted in ends 2 and 3 of the shift frame, and is adapted to be turned on its axle 4 by the usual knobs 5 or the linespacing lever 6, by means of the usual connections. A record or ledger sheet 7, adapted to receive original impressions. of the types 7* (Figure 2) through the usual ribbon (not shown), may be inserted from the rear over the usual paper table 8 and gaged at writing position approximately by the wing scales 9, in which position it may be held by the projectib-le impaling or gaging pins 10, of which there is one illustrated at each side of the front collating table 11, Said table is mounted in the usual manner on brackets 12 supported by a cross bar 13, which in turn is mounted in brackets 14 fast to the ends of the platen-shift-frame.

The table 11 carries the aforementioned pins 10, which are'adapted to be withdrawn or projected by means of the usual handle 15, which is fast to a shaft 16 carrying pinions 18, so that by rotating the handle 15 the pinions 18 will rotate and project the pins 10, by driving downwardly racks 19, which are fast to slides 20, comprising cam openings 21 for moving the pins 1( The connections between the cam openings 21 and the pins 10 include a. bar 22 at each side of the machine on which the pin or pins on its side are mounted, said bar comprising a follower 23 riding in the cam slot 21, which slot is cut diagonally of its slide 20, with the result that the raising of the slide will withdraw the pins within the table 11, while the drawing down of the slide 20 will project the pins. The slide 20 slides in hollow casin 24 held by bolts 25 to the back of the body of the table 11. Usually, in adjusting a record or ledger sheet 7, the typist projects the pins 10 before insertlng the I sheet, so that when a sheet is approximately aligned by the scale plates 9, the sheet may be pushed rearwardly and impaled upon the pins by means of its usual openings 26.

To enable statement sheets to be repeatedly and accurately inserted, there is adjustably mounted on the table 11 a directrix tangential to the platen and comprlsing adjusting plate or alignlng plate 27 closely spaced with relation to 11, and comprising a straight upper edge 29, so that when the ledger sheet 7. is in position a statement sheet 28, together with an intervenlng carbon sheet 29*, may be inserted behind the ledger sheet, so that the statement sheet and the carbon sheet, being guided by the member 11 of the directrix, pass together downwardly in front of the platen behind the ledger sheet, usually to a position beyond the front feed-rolls 30 and also frequently beyond the rear feed-rolls 31, wh1ch at this time are held cast off by their usual castingoff handle 32. Even though the ledger sheet may conceal the edge of the adjusting plate 27, the typist can accurately and quickly adjust the statement sheet 28 by feeling the edge 29 with the tips of the fingers.

In order to enable the aligning plate 27 to be easily adjusted, it comprises flat extensions 33, which are adapted to lie against the face of the table 11, and which are provided with slots 34, through which the thumbscrews 35 may pass, and be threaded into the table to enable the plate 27 to be adjusted vertically. In order to make sure that the proper adjustment of the plate 27 is obtained, the flat extensions 33 may comprise bent-over ends 36 embracin the vertical edges 37 of the table 11. To enable the aligning plate 27 to be thus utilized, it is held outwardly from the face of the table 11 by means of brackets formed by bent-over end parts 38, which form connections between the extensions 33 and the body of the plate 27 and these brackets 38 may be utilized as edge gages. The brackets 38 and the extensions 33 together form arms extending from the ends of the plate 27. In adjusting the statement sheet 28, the typist may either utilize the aligning plate 27, which is adapted to fit the statement sheet closely at each end bracket 38 thereof, or may adjust the statement sheet against one end bracket 38 of the aligning plate 27. The

aligning plate 27 may lie close to the table 11 at its lower margin 39 and may be bent outwardly from said table at the upper margin 40, thus enabling the typist to insert her fingers slightly Within the opening between the top 40 and the table 11 to render 1t easy to adjust the statement sheet by feeling with the finger tips.

In the form of the mechanism herein d sclosed, there is provided only a single pin 10 on each side of the table 11, thus allowing a large portion of the surface of the table to be utilized for positioning the alignlng plate 27 up or down to accommodate various lengths of bill heads. When the proper alignment of a statement sheet 28 and ledger sheet 7- has been obtained, the typist may manipulate the usual handle 32 to cast on the feed- rolls 30 and 31, and then if necessary rotate the platen backwardly, or, if such backward rotation is not necessary, may begin to write at once upon the lines which stand at the printing point.

This structure is especia is desired to use statement sheets that are narrower than ledger sheets, this being often desirable in machines like the Underwood bookkeeping machines, inasmuch as the right-hand marginal column 41 of the ledger sheet adjacent the perforations 26 is often used for an old balance used in proving the accuracy of bookkeeping, and the corresponding left-hand marginal column 12 is,

often used for folio numbers or for identifying data, so that both the margins 41 and 42 may contain matter which it is not desired to have appear on the statement sheet 28 which goes to the customer. Thus, having the statement sheet narrower avoids the need for the perforated margins shown in the Kidder Patent No. 1,251,241, of December 25, 1917, and enables a perfectly smooth-' edged statement sheet to be sent to the customer, this being a desideratum from the point of view of attractiveness.

Variations may be resorted to .Within the scope of the invention, and portions of the im rovements may be used without others.
