Application filed .T ul y 25, 1919, Serial No. 313,148. Renewed May 13, 1921. Serial No. 469,378.

To all whom it may concern: I

Be it known that I, J nssn A. B. SMITH, a citizen of the United States, residing in Stamford, in the county of Fairfield and rltate of Conne :ticut, have inventedcertain new and useful Improvements in Typei rits ing Machines, of whichthe followingv is a specification.

This invention relates tolthe paper-carrying devices of typewriting.machines, par

ticularly Underwood. and other round platen frontstrike machines. 7 I i One of the objects of the invention is'to improve the means rortypingentries upon work-sheets, such as shortbilbheads, that'is to say, upon work-sheets receiving entries 01" say two or three lines, as vfor example a gas-light bill. i I Hereto'fore, the use of typewriters for making out bills of this character has not been found altogether satisfactory, because of the amount or. handling" oi"? the bill. which has been found necessary in introducing the'same around the platen, thenrolling it forward and adjusting it to typing position, and proi'idiug for the making of the carbon copy, so that in practice the typing of a bill has not presented substantial advantages over the use a pen.

In order to overcome these diiiiculties,I have contrived to introduce the bill into the machine and locate it atthe typing position by a simplified operation, and in this way have made it feasible to type bills of ths character much more rapidly than heretofore found practicable, so that the type writer may successfully displace the pen in pre ring these bills. I hare'a-lso provided simple means for producing carbon copies or a succession of bills upon a single record sheet. 7 In practicing the invention in its pre 't'erred form, the bill is not introduced the bacl; of the platen, as heretofore, but is in sorted at the front thereof. The bill may be slipped down, bottom edge first, between the front of the platen and the usual platenscales, or 'wing 'scales which are arranged just in front thereof. it. plate, tablet or board is provided at the front of the platen for locating the bill. Thefingers of the operator may press the bill back against this upstanding insertion or locating-plate and by yielding Clipgg carbon is fed it'orwardl;

slide it along againsta side gage, bring the topmost blank line upon the bill to proper typing POSIEYOD crosswise of he bill.

The operator also slides the latter up against a gage provided at the top of the insertion or locating-plate. The bill may now be held The bill is now ready, because said gagesare in such positions that the bill is in correct typing position, con sidered from top .to bottom thereof. The side may be at the left-hand end. or

, the insertion-plate or aligning plate, so that the operator needs only to slip in the bill at bodily upward the'distance of one predetermined line-space, thereby advancing the bill, and may then type the next line; and this line-spacing or work-advancing operation may be performed still again it a. third line is to be written upon the bill. Upon completing the typing oi the bill, the in sertion or bill-carrying plate may be restored. to normal depressed position in readiness for receiving and advancing th next bill.

For making a carbon copy, a long recordsheet may be inserted around the platen and behind the locating and advanc ng plate,

andcontrolled in the usual manner by the iced-rolls thereon. is said sheet with its under the platen and up in front thereof, the operator. by neans of a finger-piece, may swing said locatingplate out of the way of the advancing record-sheet and its carbon, and said plate may be retured by a spring to nor- .mal position, just clearing the carbon and record-sheet.

To enable this worlclocating and advano ing plate to be used for making entries at yariousheights upon the bills particularly to bring a certain line on a bill into register with the printing line on the platen, or for I accomn'iodating bills of different sizes or for truing up the bill relatively to the printing line, the plate may be adjustably carried upon a support, and the line-spacing device for the plate may be effective on said support, thereby line-spacing the plate together with the work-sheet or bill upon it.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a perspective view of part of an Underwood r-i'iachine showing my invention as applied thereto.

Figure 2 is a sectional side view of the same, Sl10\ ring a record-sheet being inserted.

Figure 3 is a view similar to Figure 2, but showing a. bill in position and being typed.

Figure a is a fragmentary rear perspective view of the right-hand end of Figure 1.

Figure 5 is a View similar to Figure 8 but showing a bill being typed two lines lower down.

Figure 6 is a sectional detail showing av modification to effect line-spacing over greater distance.

Figure 7 is a spread perspective of some of the parts of Figure a, viewed from the opposite side.

In making out bills upon the machine shown, a record-sheet 10. together with its carbon sheet 11 is usually inserted first over the usual rear paper-table 12, and passed under the platen 18, between the platen and the front and rear feed-rolls 14c and 15. The fced-rolls may be previously cast off, if desired. by depressing the usual casting-off handle 16. The record-sheet and its carbon, after passing the front feed-roll it, pass beneath the usual paper-fingers 17, which are resiliently mounted by the usual brackets 18 upon a rear cross-rod l9, and the sheets are guided upwardly by the deflecting plates 20. The feed-rolls LL and 15 will ad vance the sheets when the platen is rotatec by the usual line-space handle 21 or the usual knob 22.

For writing the items upon a bill-head 23, it may be inserted from the front by inserting its left-hand lower corner behind and below the top of the wing-scales 24-. and be gaged against the side gage at the left-hand end of an insertion-plate or tablet 26, and be at the same time slipped upwardly on the face of the plate 26, so that its upper end catches under a spring clip 27. of which there is one at each end of the upper end of the plate 26. The bill-head is slipped up until its upper end strikes the top gage 28. which, in the illustrated embodiment of the invention, is shown as in the form of a forwardly-projecting flange along the upper edge of the aligning plate 26. The clips 2'? hold it in this position and it is then ready to be written upon if the insertiomplate 26 or front paper-table has been properly positioned, for the 28 is to be so set that, if the in sertion-plate is in its proper position the top wr'ting line upon the bill 23 is at the printing point. The insertion-plate 2.6 advantageously about the width of the billhead and its lower edge formed as a toe 29 which rests almost upon the platen, but is clear of the platen so that the record sheet 10 and its carbon ll slip easily under it.

lvleans are provided whereby t 1e aligning plate 26 is movable by line-space stages 0' intervals to occupy a series or plurality 0 different mechanically-deternlined line-space positions relatively to the printing line on the platen.

To write upon the second line of the billhead 28, the insertionplate 26 or gage-plate is adapted to be raised from its permanent position the distance of one linespace, thus linespacing the bill-head winch is carried along with it by the clips To accoinplish this line-spacing of the insertionplate 26, there is provided a. line-spacing deice including a finger-piece 30, herein shown as a knob, provided with a pointer in the form of a line 31 and which, when rotated, advances or line-spaces the insertion-plate 26. together with the sheet-holding clips 27 and loading-edge 28 carried thereby. The connection for accomplishing this includes a rock arm 31. fast upon the shaft 32, upon which the knob 30 is fast. The rock arm 31 extends into a notch or opening in a. rear supporting plate or opening 3 t, which is fast to and supports the insertion-plate being held thereto by a screw 35, threaded into an pen-- ing 36 and engz ring the margins of a verse slot 37 in the insertion-plate 26. slot provides sufficient adjustment to enable a certain desired line on the bill 93 to be brought into register with the printing line on the platen. In order to guide the insertioinplatc 26 identically at both ends. th is provided a second rock in 23-8 on the oppositc end of the rock sha'i 3,2. and the pla e 34; extends across hevond the second roi arm 33. both rock arms 3i and 3S engaging it. There are a screw and correspinidiuir slot 37 adjacent to each end of the sun'iorting plate The tablet or gage-plate i) is uzounted to occupy a single working positioin but. the screws and slots provide means for adjustment whereby it inav be trued up at the printing line or adiu ted to litlerent heights to compensate for variations of the printing of the work-sheet or bill-head. The plate 3% and the insertionplate 526 are adapted to he guided by screws of which there is one at each of the plate 34: each screw passing through a slat at) in the 3% and being threaded into a turned-over edge of a bracket il supportill?) ed on a cross-rod 42 extending across the shift frame, there being a bracket 41 at each end otttlie supporting plate 34. i

In order to mechanically determine the line-space stages or intervals and to detain the insertion-plate 26 at any mechanically 42 carries the bracket 41 by turned-up ears 4? or the bracket 41, through which the cross-rod 42 passes, and on which the bracket 41 is prevented from turnin because a key 48 is seated in a kerf 49 on the rod or bar 42, the ears being connected by a hat bail 41 The upper end 50 of one of the ears 47 is shown as riveted to an L-plate 51 which forms part of the bracket 41. It should be understood that the brackets 41 are slidable along the supporting rod 42, to provide,

for adjustingthe aligning plate 26 longitudinally of theplaten 13.

To facilitate the passage of a record-sheet and its carbon beneath the insertion-plate 26, the plate is adapted to be swung far enough away from the platen to clear the record-sheet even though the sheet is so wide that it bellies out considerably between the fingers 17. To accomplish this, the bar 42 is shown as rotatably mounted in ears52 of brackets 53, which are adapted to fit upon the cover-plates 54 of the ends of the shift frame, and to be held thereto by means of thumb-screws 55 adapted to be screwed into the usual threaded openings insteado'f the screws which usually held the cover -plates in place. To permit the rod'42 to rock the plate 26, it is yieldingly held against turning by a key 56, which lies between the ears 52 of one or both ot the brackets '53, and

which is adapted to be pressed into the kerf 49 by a'spring 57 of ordinary form To enable the typist to easily rock the insertiouplate 26, the rod 42 is'adaptedto be turned by a finger-piece 5Sheld fast to its end by means of a screw 59. It will be observed that the plate or frame 34 forms an intermediate support or mount whereby the paper-table is carried upon rod 42, and that the latter'also forms a main support where by both table and frame 34 are carried upon the platen-frame As illustrated in Figures 1 to 4, inclusive,

the billhea-d is adapted to betyped upononly three different line-spaces. The permanent position of the table 26 is when the detent and locator 43 is in the top notch 45. To enable, the bill head to be typed'at a larger number of line-spaces, the rod or shaftez, as shown in Figure 6,may be provided with a. pair of pinions 60 fast to it and meshing with ranks 61, respectively, re-

placing-the rock arms 3]. and 38 and the notches in which saia rock arms operate.

As illustrated in Figure 6, the spring detent 43 is adaptedto seat itself in any one of tire notches 45, thus providing for one permanent position and l our temporary positions of the table and gage 28. A bill-head to receive five line-spaces would have only four spaces below the top printing line, and this much of a bill-head can easily be accommodated below the printing linein the ordinary Unoerwood typewriting machine, above the segn'ient 62 and behind the wingscales 24. v

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, 1
