which is mounted upon and turns With the platen-shell and is adopted to be turned orrotetcd relatively to the platen and to reinzun, at any point to which. it mey be moved it) indicates an index finger or point-er or adjusted. So far as the general ends to be attainal are concerned, thepointer 10 may be engaged with the platen-shaft by any form of device adapted to hold said pointer from freely turnin on the platenshaft while adapting it to be turned or rotatively shifted on the shaft by the hand of the operator as desired. Likewise, the disk 6 may be connected with the frame of the machine by means adapted to retain the pointer 7 thereon in any position in which it may be placed or to which it may be ad justed with respectto the fixed pointer 9, by the turning of said disk 6, while enabling said disk 6 to be turned for shifting or adjustingthe position of the pointer when de sired. In the embodiment of my invention illustrated in the-drawings, the pointer 10 is frictionally engaged with the shaft so that it turns' with the shaft but may be readily turned thereon to effect its adjustment while the disk 6 is held in adjusted position rela tively to the carriage-frame by an interlocking connection between said disk and the end-plate 2. v

Now referring to the details of construction in the features above referred to, illustrated in the drawings, the disk 6 has a central bearing aperture to receive the sleeve 4 and is held in place on the sleeve by means of a retaining collar 11 which surrounds the sleeve outside of the disk and is secured thereto by a screw or other attaching means. For adjustably'holding the disk 6 from rotation, a spring detcnt 12 is attached to the outer face of the end-plate 2 and is provided with a holding prong 13 adapted for engage-J ment with either one of an annularly arranged series of radial notches 14, 14 formed on the inner face of the disk. The spring detent is shown. as having the form of a leafspring, one end of which is attached to the end-plate, with its free end extending outside of the disk, in position to be easily pressed by the finger. The holding prong 13 is formed on said spring-arm between the ends of the same, and is held normallyin position to engage the notches of the disk 6 by the resiliency of the spring-arm; which latter is pressed toward the cnd-plato to release the holding prong from the disk.

The pointer 10 is attached to a sleeve 15 which is mounted to turn on the platenshaft outside of the disk 6. Said sleeve is provided with a l nurlcdflangc 16 by which said sleeve 15 and the pointer 10 may be easily rotated on the shaft by the fingers. Frictional connection between the sleeve 15 and the shaft is afforded by means of a concave, sheet-metal, elastic spring-ring or washer 17 located within a concentric recess formed in the inner face of the sleeve 15,.said washer being interposed between the adjacent or outer ends of the sleeve'4 and the colla'r 11. thereon and the bottom of the recess in the sleeve 15. Said sleeve 15 is pressed toward the bearing-sleeve 4 and the springwasher 17 maintained in bearing contact with said parts by the collar 18 of'the turning-knob '5, the inner end of which collar forms a shoulder against which bears the outer end of the sleeve 15.

The operation of the indicating device described will be understood from the following: The general purpose of the paper-movement indicating device is to indicate to the opera or the extent to which the platen must be turned backward when insertinga sheet of paper into the machine in order to bring the first line of printing the desired distance from the top margin of the paper, according to the space occupied by the heading on the sheet. More particularly, the indicating device is designed for use in cases where it is desired to make out a number of bills or invoices and to make carbon copies of the same on a single record sheet. sirable that the copies should be spaced as .closely as possible on the record sheet but at uniform distances apart, or with equal spaces.

between several records or copies, and the indicating device is employed to enable .the operator to readily insert a new sheet foreach In a case of this kind, it is de- 5 separate original bill or invoice in such a manner that the first printed line of the carbon copy shall be located at a desired dis tance from the last printed line of the preceding carbon copy. 7

In using the indicating device described, the operator sets the disk 6 with the pointer 7 thereon at an angular distance from the fixed pointer 9, equal to the distance which it is necessary to turn the platen backward after printing the last line of one bill or invoice in order to start a new original sheet into the machine in such manner that the first line of the next bill or invoice when started at its proper place on the sheet will, on the carbon copy sheet, come at a distance desired, as

two, three or four line spaces from the last line of the preceding carbon co y. The

setting of the disk 6 is effected as to lows: In the case of an Oliver typewriter, one of the original sheets or blanks for a bill or invoice, which usuallyliassrprinted heading, is inserted in the machine with its advance margin against the lower guide roller or gripping roller by which the sheet is fed forward, and in position to be gripped and fed forward when the platen is turned in its usual feeding direction. The platen is, at this time, turned to bring the zero mark of the scale on the disk 8 (marked 26 in the drawing) in line with a fixed part of the papercarriage, such as the fixed pointer 9 or the edge of the scale-bar of the machine.

The platen is then turned to feed the paper forward until brought into position for printing the first line, which is usually the date line.

The platen is then turned forward a space of ceases- .two or three additional lines according to the distance desired between the carbon copies on the record sheet. The operator then notes the mark on the scale on the disk 8 which is then in line with the fixed pointer. This may be 32, indicating that the platen must be turned back thirty-two line spaces to bring the same in position for the insertion of a new sheet. lie then releases the-disk 6 from the paper-carriage and turns said disk until the scale-nnu'k 32 thereon comes in line with the lined pointer 9, thereby bringing the pointer 7 at a distance from said fixed pointer equal to the distance the platen was turned in advancing the paper. That is to say, the pointer ,7 is placed at an angular distance backward from the fixed pointer equal to the angular distance the platen was turned forward from the zero point in advancing the paper; this distance having been noted at that time, as above stated. The angular distance between the fixed pointer 9 and the adjustable winter 7 will then be equal to the distance which it is necessary to turn back the platen for inserting a new sheet, this distance being represented by the length of the heading on the blank bill or invoice, plus the distance around the platen from the gripping; roller to the striking point of the type, plus the space to be left between the carbon copies .on the record sheet. The parts will now be adpistcd [or use in connection with the same bill or invoice heads or sheets, so long as it may be desired to use the some.

hi the use of the device in printing, the bill or invoice sheet and the record sheet are inserted into the machine, with the carbon paper between them, in the usual manner. Atter the printing of the first invoice is finished, on completion of toe last line thereof the sleeve 15 will be turned on the platenshat't to bring the pointer 10 thereon opposite the lixed pointer 9 and the said pointer 10 will be allowed to remain in this iosition. 'l he platen will then be turned forward far enough to remove theoriginal sheet and then turned backward until the pointer It) is carried past the fixed pointer t) and around thcdisk until itreaches the adjustable pointer 7, when it is stopped. 'lhe platen will then e in position for the insertion ol the next original sheet, which will be inserted by thrusting it into the machine until its top edge comes in contact with the lirst g'uidcroller by which the sheet is gripped to the platen, and the platen will then be turned lorwardlv to carry the record sheotand the new original sheet into position for printing the lirst line on said new original sheet.

it follows that by the use of the device described, the pperator havingonce determined the angu ar distance or number of line spa es through which the platen'must be turned backwardly. bel'orrv starting a new sheet into the machine, in every instance, or

when inserting each new original sheet for an original bill or invoice, is enabled to invariably turn the'platen backward the same distance, according to the angular distance between the fixed pointer 9 and the adjustable turned backward to the extent or nearly or somewhatmore than a ccuuplctc rotation, whether the bill-heading be wideor narrow, it is unnecessary that the disk 6 should have its scale-marks numbered with the lower numbers of the scale, and it is also unnecessary that the pointer 7 should be placed -at the zero-mark 0 said disk 6. in order that said pointer 7 may be located, for bill-heads of the more commonh used widths, at the forward and upper part of the periphery of the disk 6', where it ma be more easily seen, the said disk is numbered to corres'iond with the line-space distances which will include the usual range of angular adjustment re uircd in the pointer? with respect to the liXe pointer 9, and the said pointer 7 is placed at a point on the disk which may be arbitrarily selected but which must corr0- spoiid with the location of lh'elixed pointer on the frame. in the instance illustrated, in which the platen has twenty-six line spare movements for a complete rotation and .a fixed pointer 9 is located above and in verticalalinemeut with the axis of the platen, the marks on the disk 6 are numbered from 20 to and the pointer 7 is placed at the mark 26. In this arrangement, "if the platen is to he turned backward less than a complete rota- .tion, then oneof the marks to will be placed opposite the fixed pointer 9 and the pointer 7 will stand rearwardly from said fixed pointer. It follows that, when the pointer 1.0 is placed opposite the fixed pointer 9 and the platen turned backward, the said pointer 10 will be moved from the fixed pointer backwardly tothe pointer 7 and w ll make, with the platen, less than a complete rotation. If, however, as is more usually the case, it be necessary to turn the platen backward more than a com )letc rotatirm, say fro1n27 to line-space distances, the disk (3 is turned to bring the desired scale-mark thereon, say 33, op iosite the fixed pointer and the winter 7 in l then stand forward of the fixed pointer. When theparts are'thus adjusted, m turning the platenbackward after the pointer 10 has been placed opposite the liked pointer, the platen will be turned a complete rotation to carry the said pointer 10 around to the lixed pointer, and then forcarbon copies on cover or Y l so thei turned to carry said ointer beyond or forward of said fixed pointer until it reaches the pointer 7 in its second rotation. The arrangement described is a convenient one, because, within its usual range of adjustment, the pointer 7 will stand either a short distance to the rear of the fixed pointer,

. or at some point forward of said fixed pointer on the forward half of the periphery of the disk 6, so that it can be easily observed by the operator at the time the backward turning of the platen brings said pointer 10 adj acent to or opposite said pointer 7.
