JESSE A. B. SMITH OF STAMFORD, CONNECTICUT, ASSIGNOR TO UNDERWOOD TYPE- WRITER COMPANY, OF NEW YORK, N. Y., CORPORATION OF DELAWARE.

TYPEWRITING MACHINE.

To all whom it may concern Be it known that I, JESSE A. B. SMITH, a citizen of the United States, residing: in Stamford, inthe 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 means for facilitating the proper relative positioning of work-sheets on a platen, and is herein dis closed as applied to the Underwood standard typewriting machine.

In the class of work to be handled by machines to which this invention is applied, names and addresses or the like are'to be written on a record-sheet and carbon copies made onbills or forms, which are fed into the machine in strips, each of which comprises a plurality of said bills or forms. If

desired, carbon copies of the names and ad-- dresses may also be made on a tally-strip. Inasmuch as the printing of the names and addresses on'the record-sheet is to check up the writing of the names and addresses on bills or forms to befilledout later, it is desirable to have successive names and ad- I dresses written close together on the recordsheet, while the names and'addresses on the strip of bills are comparatively far apart. In carrying'out this invention,-the strip of forms is delivered from the platen to a paper-table which may be adjustable in width, and also adjustable as a whole parallel to the axis of the platen. Provision may be made of a leading-edge-gage on the paper-table.

The record-s ieet may be supported above the paper-table by suitable means such as arms parallel to the axis of the platen, the forward edges of said arms being in alignment and serving as a means for properly" gaging the leading edge of the record-sheet when the latter is introduced into the machine.

In order tofacilitate the positioning or collating of the record-sheet and the formstrip, so that a formsubsequent to the first may be properly positioned relatively to the record-sheet, provision is made of a suitable bail, swingable to and from effective position,and of means tending to hold said bail in either itseffective position or in an ineffective position. The bail may be provided with suitable means, such as rolls, to press the record-sheet against, the aforesaid arms Specification of Letters Patent.

member, adapted to-enteraperforation in the form-strip when the perforation is brought into register with an aperture in the paper-table. Obviously, a plurality of spring-pressed'pins may be used, the forms or bills and the paper-table being modified to vco-operate therewith.

It should be understood that before the introduction of the record-sheet and the form-strip, with a suitable carbon-sheet therebetween, the usual feed-rolls are cast off in theusual manner. The leading edge of the record-sheet is' then brought into co porting arms, and the leading edge of the form-strip is brought into engagement with the leading-edge-gage on the paper-table. hen desired, the bail may be thrown into effective position after the record-sheet has been properly gaged, in order to hold the record-sheet inposition while the form-strip is being brought into engagement with the leading-edge-gage on the papertable. The feed-rolls may then be restored to normal position, to enable feeding of the recordsheet and the form-strip withthe platen, and the bail thrown to ineffective position so as not to interfere with the feeding of the record-sheet and form-strip.

After Writing the name and address on two or more lines, the platen may be linespaced to advance the record-sheet into position of the first line of the new name and address. The bail may then be thrown to effective position, to press the record-sheet against the supporting fingers and to bring the spring-pressed pin into engagement with the form-strip. The usual feed-rolls may then be released from the platen, and the form-strip drawn forward until the springpress ed pin" drops into a perforation brought into register with an aperture in the paper-table, thus automatically arresting the form-strip or sheet. A new form or bill will then be properly positioned for receiv'ing'the first line of the name and address thereon. 'The 'feed-rolls may then be restored to effective position relative to the platen, and the bail withdrawn to ineffem,

' The revoluble platen 1 is supported, by

means of. anaxle 2, inend-frames 3 of the platen-frame 4. of the '11S112Ll Underwood typewriting machine, and the platen may be fed by means'of a finger-wheel 5 on the axle, or by means of a line-space" lever 6, acting through a slide 7 and a pawl 8, to drive a line-space ratchet-wheel 9 fixed on said axle; 2. The extentof such actuation of the line-space ratchet may. be determined by the position of-a regulator 10. v

The line-spacing mechanism just described is, in general, similar to that disclosed in the patent to Frederick .A. Hart, N0.

1,281,160, dated October 8, 1918.

In order that t-he work may be fedforward by the platen when the latter is actuated either by the finger-wheel 5 or. the.

line-space lever 6, provision may be made voi ,front feed-rolls 11 and rear feed-rolls 12, supported by levers l3 and 14, respectively, said levers being pivotallymounted on a shaft 15 and normally urged. by suitable springs (not shown) to press the feedrolls against the platen. When it is de sired to release the feed-rolls 11 and 12 for any reason, a feed-roll-release lever 16 maybe operated to move a link 17 and an and thereby move levers 13 and 14 to withf disclosed in said patent to Hart, No.-

The bill-strip 20 (Figure 6), when inserted in the machine, may be received by a paper-table 21 adjacent the delivery side of the platen, said paper-table 21 comprising sections 22 and 23 having edge- guides 24 and 25, respectively. Said sections 22 and 23 may be adjustable with respect to each other to vary the width 'of-the paper-table, and secured in such adjusted relation by any suitable means, such 1 as indicated 'at 26.. The

sections22 and 23 may also. be provided with slots- 27, through which pass screws 28, threaded'into a support 29, which, in turn, is-connecte'd at its ends to plates 30 supported by rods 31. Said rods 31 may be -supported in any desired manner on" the platen-frame;

Said section 22 of the paper-table may be .provided with a leading-edge-gage 32, preferably formed by" being struck upwardly from said. section 22.

In order to support the record-sheet 33 so i that it will be spaced from said paper-table 21 brackets 34 and 35 are attached to support 29at the left and right, respectively, of the'paper-table 21, and are provided with arms .36 .and 37 parallel to the paper-table and spaced therefrom. These arms serveto support and guide the record-sheet as it is delivered ltrom the platen. It will be noted that the arm" 36 of the lefthand bracket extends .to'theright, and that the arm 37 of .the right-hand bracket also extends to the right and is provided with a side-edge-gage 38. It should be understood that the record- The arrangement just described enables the use of a record-sheet wider than the in properly positioning the record-sheet when first introduced into the machine.

When it is desired to insert a record-sheet and a 'form-strip, with a carbon-sheet i-nterleaved therebetween, into the machine, the

feed-rolls 11 and 12 are released, the recordsheet is positioned by means of the aligned edges of arms 36 and 37, and the leading edge of the form strip is brought-into engagement with the leading-edge-guide 32.

The feed-rolls 11 and 12 may then be restored to effective position. Such positioning of the record-sheet and the form-strip may be facilitated by providing means for holding the record-sheet in position on arms 36 and 37 while the form-strip is being brought to proper position. Such holding of the record-sheet may be obtained by means of feed-rolls 39, :mounted on a rod forming part of a bail 40, which is supported, by means of arms 41 forming part thereof, on shafts 42. Said shafts 42 may be journaled in plates 43, secured to the respective end-frames 3 in any desired manner. In order to maintain the bail in effective position with the rolls 39 in contact with arms 36 and 37, or in a position withdrawn therefrom, shafts 42 may be provided with heads 44, having recesses 45 properly shaped to receive circular disks 46, carried by arms 47, pivoted .at- 48 and urged bysprings 49 to force said disks 46 into the recesses 45. Said feed-rolls 39 may be shiftablealong the rod the name and address thereon. As'indicated in Figure 1, the left-hand edge of the recordsheet is positioned to the right of the corresponding edge of the bill-stri so as to avoid interference, by the record-s eet, with said pin 52. Said pin 52 may be supported in a sleeve 53 on an arm 54, attached by means of screws 55 to the arm 41 at the left, as seen in Figure 1, and may be pressed toward the paper-table-by means of a light spring 56, movement of the pin by the spring being limited by means of a nut 57 at the upper end of a stem 58 forming part of said pin.

After the record-sheet and form-strip or bill-strip have been placed in the machine, as shown in Figure 3, the bail 40 may be swung forward to the position indicated in Figure 5, and typewriting effected by means of type-bars 59, striking through a ribbon 60, to print on the record-sheet '33; a copy of such typewriting being obtained on the billstrip by means of a suitable carbon-sheet 61 When desired, a tally-strip 62 and carbonsheet 63 may also be used. The feeding of the tally-strip may be effected by suitable means such as disclosed in said patent to Hart, No. 1,281,160. I

After writing each line of the name and address on the first bill, the platen is actuated by the line-space lever, the last actuat1on thereby serving to advance .the recordsheet to a position, for writing the first line of the second name and address thereon. The bill-strip will not, however, be properly positioned to receive the carbon-copy of the second name and address. In order to effect such positioning of the bill-strip, the bail may be swung to the rear, so that rolls 39 will press record-sheet 33 against arms 36 and 37 and will bring pin 52 into yielding engagement with bill-strip 20, as indicated in'Figure 4. Feed-rolls 11 and 12 may then be released, and bill-strip 2O drawn forward until the next aperture of perforation 50 in the bill-strip is brought into register with the aperture 51, whereupon pin 52 will assume the full-line position shown in Figure 5. The feed-rolls 11 and 12 may then be restored to effective position, and the bail swung away from the paper-table, as indicated in Figure 5. Obviously, the shifting of the bill-strip will be effected in the same manner for any subsequent bill.

Instead of using separate perforations 50 in the bill-strip, as indicated in Figure 6. the perforations between the detachable forms or bills may be utilized. In this case, the individual perforations may be made somewhat larger, as indicated in Figure 8, and the single spring-pressed pin may be replaced by a device such'as shown in Figures 9 and 10. Vith this arrangement, when the bill-strip is advanced to bring the line of perforations 64 into proper position, certain perforations may be engaged by a plurality of pins 65, mounted upon a modified form of arm 54, and light-ly' pressed to effective position by spring-fingers 66, which may be formed as part of a single plate 67, secured on the supporting arm. As inclicated in Figure 11, one or more of the independently-movable pins may register with and enter perforations between forms or bills although others do not. It is apparent there fore, that accurate positioning of the perforations in the lines of division is not so important as in the case where each form is provided with a single perforation to coclaim:

' paper-table, or provision mag operate with a single pin. In connection.

with the use of the plurality of pins 65, an elongated opening 68 may be provided in the be made of one'opening for each pin. bviously, the device shown in Figures 9 and 10 may be used in connection with a bill-strip having a line of perforations different from and in addition to those between the separate'bills.

As shown in Figure 7, the record-sheet a spring-pressed pin to co-operate with per forations in a secondwork-sheet, todetermine the proper positioning of the same at different times, and means to concomitantly render said gripping means effective and cause said spring-pressed in to yieldingly engage said second work-s eet, so that the latter may be drawn forward with reference to the first-worksheet until said pin enters one of said perforations in the second sheet and revents further movement thereof.
