Application filed May 10, 1913. Serial No. 766,672.
cating devices for use on typewriting maespecially adapted for what chines, and is condensed record is commonly known as work. In work of this character, bills or invoices are made out on sheets rovided with printed forms or headings, which sometimes occupy considerable space. Carbon copies of the typewritten portions of a number of bills are made on a single record sheet or ledger sheet which is usually longer than the individual bill sheets, the carbonrecords being printed in succession on the record sheet, and each occupying generally a comparatively small space.
An object of my invention is to provide improved line-space indicating scales and means in connection therewith to control the positions of the scales relative to the platen. and thereby facilitate the removal of a bill.
and replacing of a new bill sheet on the record sheet by indicating the exact distance the platen is to be rotated. Parallel finger wheels or disks are loosely mounted on .the platen axle and independently rotatable On the periphery of each' disk is a series'of scale numbers at line-space distances 'apart,the numbers being in the opposite order on the twodisks. An indicator arm on the platen frame extends over the disks and in the path of stops on the disks, each stop being locatedadjacent tothe scale number 1 onits disk. Each stop is held in a projected position, but is adapted to yield in one direction and allowthe. stop to .pass the said arm to .permitthe'use of the indicator when the platen is rotated more or invoice sheet to writing position.

The present invention is a modification of the nvention shown in patent to Briggs 916,099, and is herein shown as applied to a Rem ngton No. 6 typewriter, although it is to be understood that the invention is applicable to other typewriting machines. The traveling carriage 1 is supported on rollers 2, which travel on a stationary rod or rail 3 mounted on the top plate of the machine.
The platen frame 4 is supported on its rear side by means of links 5 connected with the carriage, and at its front'side by means of a roller 6, which travels on a shift rail 7 The platen 8 is rigidly secured to the platen axle 9, journaled in the end bars of the platen frame. The platen frame comprises a bar 10 to which are pivoted hangers 11 which support a shaft 12- carrying the usual feed roller or rollers 13. Springs 15 secured to the hangers 11 by screws 16 engage lugs 17 projecting from the bar 10, said springs normally pressing the feedrollers against the platen. The feed rollers may be d-isen gaged from the platen by means of a finger piece 18 forming the end of a crank arm, which is rigidly mounted'on a rock shaft 19 pivoted in the platen frame, said rock shaft is provided with projections 20 which engage the ban ers 11. When pressure is applied to the ngerpiece 18the projections 20 bear against the hangers 11 and lift the the righthand of the platen roller is mounted a linespace ratchet'wheel 21, with which cooperates a feed dog or pawl 22 to feed the platen forward in the usual way; The pawl 22' is'pivotally mounted on an arm 23,'which is connected to the platen flQm6 .by"-8)P1V0t 24, said am being integral withthe usual carr age returning Iine=space lever '25; Se-

' d" in frictional'gcont'act with The line-space-indicatmg mechanisin'coin said flange by means of leaf springs 32 bifurcated to straddle the hub and held in position by annular grooves 33 in said hub.
On the periphery of the disk 28 is a linespace scale comprising numbers 1, 2, 3, etc., at line-space intervals, the numbers corresponding in number and position to the ratchet teeth on the line-space wheel. On the disk 29 is a similar scale but the numbers in this instance are arranged in the reverse order. The scales are preferably printed in different colors or on differently colored backgrounds, or are otherwise provided with distinguishing characteristics.
Secured to the platen frame is an indieating or index arm 35, projecting over the disks and located in the path of the stops 36 and 37. Each of these stops is pivoted in a recess 38 formed in the disk and is held in a projecting position by a spring 39; thus the stop 37, as shown in Figs. 4 and 5, is projected in a position to be intercepted by the arm and thereby prevent the rotation of the disk 29 in a forward direction beyond the position shown in Fig. 4. Stop 37,
however, will yield in the opposite direction to pass the arm 35 during the backward rotation of the disk. The stop 36 is likewise yieldable .to permit it'to pass the stop arm 35 but in the reverse direction. The under surface of the arm 35 may be beveled to assist in camming the stops 36 and 37 downward as the latter pass beneath said arm.
The inventionmay be used as follows:
a The scales are rotated on the platen axle to the position shown in Fig. 1 with the stop tion until the printed heading on the invoice sheet has passed beyond the printing line and the sheet is in position to receive the typewritten recordQ During this forward rotation of the platen the disk 28 is carried therewith, the disk 29 being held stationary by the stop 37 in contact with the arm 35. When the work sheets are thus in position for writing, the scale number on the disk 28 appearing directly over the indicator arm 35, is noted. Assuming, for example, that thisinumber is 247 as shown on Fig. 4, it indicates that the platen has been rotated a distance of twenty-four line-spaces in bringing the work sheets into writing position. After the desired record has been made on the invoice and record sheet, which record may comprise one or more lines of typewritten matter, the platen is rotated backward carrying with it the disk 29 until the scale number 24: thereon appears directly below the indicator 35; that is, the platen is rotated backward through twentyfour line spaces, or in other words the platen is rotated backward through the same distance as it was rotated forward to bring the invoice sheet into position to receive the first line of writing, the opposite reading'of the numbers on disk 29 enabling the operator to placed on the machine after the pressure rolls have been returned, and the platen is rotated in a forward direction until the stop 37 is again brought up to the arm 35. The new invoice sheet is now in position to receive its typewritten record. The record sheet is also in advance of the invoice sheet a distance corresponding to the number of lines written on the first invoice sheet, that is,the record sheet is in position to receive a second invoice record directly below the first. The spacing between the records on the record sheet may be effected by operating the line-space lever after each invoice sheet has been completed but before the platen has been rotated backward to permit the sheet to be removed. When the second invoice record has been completed the platen is again rotated'backward as before until the number 2 on the disk29 appears below the arm 35. The second invoice sheet is now removed the same as the first and the cycle of operation is repeated as many times as desired or until the available space on the record sheet, is filled. If the printed heading on the invoice sheet is of such depth as to require more than a complete rotation of the platen to bring the sheet into position for writing, .the stop 36 will be brought around to the lower side of the arm 35, and pas behind andbeyond said arm to a point above the'arm duringthe insertion of the sheet. This will be noted bythe. operator and when the invoice sheet is in position the number directl above'the arm 35 will be noted as before. If we assume for example,
that the disk 28 hasmade more than a complete rotation and the number 4 appears above the indicator arm, then when the in-' voice-sheet isbe-ing removed from the machine the platen is rotated backward more I than a complete rotation, the swinging stop 37 on the'disk 29 passing beneath the indi- 'Vdicating arm 35, indicate to the operator the cator arm 35 and the rotation being continued until the number 4: on the disk 29 appears below said-arm. The platen is now in position for the invoice sheet to be removed as before and another sheet placed in position. i
It will be seen that the disk 28 with its scale serves tomeasure the number of line spaces from the upper ed e of the invoice, bill or work-sheet to the ing, and after-this number has been determined for the first of any series of worksheets with equal top margins or headings, the disk 29 is used to gage the forward and backward rotation of the platen in positioning work-sheets thereon and removing them therefrom. I
The present invention is also adapted for use as a page indicating device to enable the operator to determine when the work-sheet has been completed or written upon to'a point within a predetermined distance from the bottom edge :of the'work-sheet. For this purpose either of the indicator wheels or disks may be employed. If the disk 28 .is used for this purpose, it may be set as in Fig. 1, prior to the insertion of a worksheet, so that as the work-sheet isfed forward during the writing of the page, the
line-space numbers on said disk appear in] succession above the indicating arm 35, and thus indicate the distance of the printing line from the top 'of the work-sheet. The
distance from the top edge of the sheet tothe last line it is desired to write on the page, being known or determined by experiment, the numbers on the disk as they pass the innearness of the sheet to position to receive the final line of writing. For example, with a work-sheet on which the bottom lineof writing is twenty-four line-space distances I ,-from the top edg'e,--
the disk. 28 when it reaches the Fig. 4- position'with. the line space number 24 above the indicating arm, shows line of writing has been reached. It will be noted that the disk is equally well adapted in this instance of the page.
for useas a page-end indicator with a worksheet of such length that more than a complete rotation of the platen takes place during the writing of the page, as the stop 36 the arm 35, and more times during the depending on the length may do so one or writing of-a page,
as a page-end indicating device, the disk being so set that it will be brought to the Fig. 4 position when the work-sheet is in positionto receive the last line of writing. In other .words, the disk 29 is set'prior to the insertion of the work-sheet so that the numberbelow the indicating arm 35 represents the number of line-space distances the descending order,
rst line of writto positively that the position for theulast.
' eating numbers The disk 29 may also be used from "the top edge of the work-sheet to the last line of writing on the sheet, and, therefore, the numbers on the indicator which pass the indicating arm in v indicate directly the number of lines to be written to complete the work-sheet. The operator may thus tell at a glance the nearness of the worksheet to the last line position, by noting the indicator number at the gage 35.
Variations may be resorted to within the scope of theinvention, and portions of the improvements may be used without others.

In a typewriting machine, the combination with a rotary platen, of an indicator having a friction driving connection with the platen, causing the indicator to rotate with the platen and permitting the platen to rotate independently of the indicator when the latter is restrained, a stop to limit the backward rotation of the indicator with the platen but permitting an unlimited rotation of the indicator with the platen in a forward direction, a series of numbers on said indicator to indicate rotations of the 'platen through line-space distances, and an index or pointer past which saidnumbers are carriedduring the rotation of the indicator with the platen, saidgpointer positioned at the first number of said series when the indicator is at the limit of its backward rotation determined by said stop, said numbers passing the pointer in the ascending order as'the platen is rotated forwardly.
15. In a typewriting machine adapted for use as a billing machine, the combination with a rotary platen, of indicating mechanism to indicate the extent of the forward and backward rotation of the platen for inserting and removing bills or work-sheets, said mechanism comprising an indicator frictionally connected to rotate with theplaten and permitting independent rotation of the platen when the indicator is restrained, a stop on said indicator to limit the backward rotation of said indicator, and permitting unlimited forward rotation thereof, a series of numbers on said indicator, and a stationary arm forming a counter-stop for said stop, and also forming a pointer past which said numbers are carried as the indicator rotates, said pointer being at the beginning of said series when the indicator is at the limit of its backward rotation determined by said stop, said numbers being carried past the pointer in the ascending order as the platen is rotated forwardly.
16. In a 'typewriting machine adapted for use as a billing machine, the combination with a rotary platen, of indicating mechanism to indicate the; extent of the forward and backward rotation of the platen during the placing and removal of bills or worksheets on and from the platen, said mechanism comprising an indicator frictionally connected to rotate with the platen and permitting independent rotation of the platen when the indicator is restrained, a stop to limit the backward rotation of said indicator and permitting unlimited forward rotation thereof, a series of numbers on said indicator, a stationary pointer past which said numbers are carried as the indicator rotates, said pointer being at the beginningpast the pointer in the ascending order as Y the platen is rotated forwardly to bring a bill or worksheet into position to receive the first line of writing, said bill having been placed on the machine when the indicator is at said stop position, whereby the said numbers indicate directly the distance through which the platen is rotated, a second indicator frictionall connected to rotate with the platen and permitting independent rotation of the platen when said second indicator is restrained, a stop to limit the forward rotation of said second indicator but permitting unlimited backward rotation thereof, and a series of numbers on said second indicator arranged to move past said pointer in the ascending order as the platen is rotated backwardly, said pointer being at the beginning of said last-named series of numbers when said second indicator is at the limit of its forward rotation, whereby the distance through which the platen is rotated backwardly to bring the bill or work-sheet into position to'be removed from the machine, is indicated directly by the numbers on said second indicator.
