'lhc parts aborc dcscrihcd correspond with thow ot the paper-carriage of an Oliver typcu'ritoi' machine in which the type-bars arc locatcd above the platen and the types :il'llit tlou'nwardly upon the top surface thereof.

Now rclerring to the parts constituting rhc dcY'u-c cmhodying my invention, 'the same, as illustrated in tho Stlltl drawings, are constructed as follows:

1 indicates a gcar pinion mounted on the platcn ahat't olilRitle of the and plate B of the carriage frame and arrhnged either to turn with or to turn on said platen shaft hv illtttllH of a clutch tlcvicc operated through t-hc ondwisc niovcuicnt. oi. the pinion on the shaft. in the particular construction shown, said pinion is inount'cd on tho slccre l: of the turning knob in such manncr as to have both cndnisc and rotatirc inovcinont thoroon. Said pinion in providcrl on its inncr or lci't-hand taco with a scrics of radial notches, as (:lcarl t' Fttll in Fig. T, and the slccrc ii is proridod with a radial pin 11 adapted to cngaggc any tmt of said notchcs and to ho brought into cngagcnicnt thcrcwith or disconatruction shown. the spring 1 has the form of a spirally coiled spring surrounding 'the'slccvo I: and attached at its outer pad to the :lattcrf 'Ihc inncr cud of said spring 'lwars against an annular outwardh facing hcariug surfmre or sliouldcr on-sai 'pinion.

Said pinion is shown as provided with 'a tubular cxtons on or slcc-rc i which surrounds J indicatca a gear wheel mounted on the oa-rriagc t'ranie by means of a p vot. stud JR. and which intcrnicshcs-with the pinion I.

l Thc pi ot stud 'J' is located at the rear of Ito the platen shaft and above and at the rear of the rock-shaft G; the parts being so arranged that the rim of the wheel is located radially outside of the hub of the lever G. Said rim of the wheel is, moreover, connected with the pivot J by a sin le, radial arm J so that the wheel is adapted to swing to a, desired distance without contact will the said hub g of the lever G.

evices are provided by which the 1ggar pinion I is automatically disengaged m the platen shaft in the forward turning movement of the platen and is thrown into engagement with said platen shaft by the backward turning movement of the aten, as follows: Attached to the pinion is a radial arm I which overlaps the rim of the wheel J at the outer or ri lit-hand face of the same The said gear w eel J is rovided on t e outer or right-hand face 0 its rim with a cam pro'ection J having. a beveled or inclined sur ace 7' on the side thereof .which comes in contact with the arm I when, in the forward turning movement of the platen, the pinion I turns the wheel J into position to bring the said cam projections J into enga ement with said arm 1 as 'seen in Fig. 3. he pinion I intermeshes with the earwheel J in such manner that the arm will;coincide with the cam projection J hen in the turning movement of the pin" n the arm I is directed toward the center of said wheel J. The cam surface 7' of said cam projection J is adapted to enter behind the arm I in such manner as to press or force said arm toward the right, and to thereby move the arm and gear pinion outwardly on the platen shaft far enough to release the gear pinion from the pin it and to thereby hold said pinion disconnected from said platen shaft. The said cam projection J is located on the rim of the wheel J at a point adjacent to the supporting arm I of said wheel, so that said cam pro ection 'will be engaged with the arm I at a time when the gear wheel J is turned to bring the said arm J 2 in a 0sttion in which .it extends forwardly om the pivot J, or toward the platen shaft; this being the limit of the turnin movement of the said wheel J in the irection in which it is turned in the forward turning movement of the laten. Preferably the rotation of the whee J, in this direction is limited by means of a stop projection adapted to strike the hub g. of the lever as seen in Fig. 3. As hereinbefore stated, the 5 ring I is adapted to produce frictiona engagement between the platen shaft and the pinion I and i' follows that when the-:said pinion is he] in a" osltion free fromen a' ment with the 'pn' hhy the action 0 t e cam projection J on the arm 1*, in the manner above described, if the.

platen shaft. be turned backwardly the frictional engagement between the said shaft and the pinion I will effect the turning of the latter with the shaft. It follows that when the cam projection 1 is en aged with thearm I and the parts are in t e position shown in Fig. 3 backward turnin of the platen shaft will result in the sai inion I and the arm I thereon being turne backwardly, producing a reverse rotation of the gear wheel J and carrying the said cam projection J out of engagement with the arm I", thus permitting the gear pinion to become ree'nga ed with the pin It and the pinion to be t ereby locked to the platen shaft. It follows that soon after the beginning of he backward turning movement of the platen shaft, when the parts are in the position shown in Fig. 3, the pinion will be locked -to said latenshaft and will then positively turn t e gear wheel J It follows from the above'that the cam projection J and the arm I on the pinion constitute in effect a clutch.operating device by which the pinion I is automatically disengaged.

from the platen shaft by the forward turning movement-of the platen and is ret ngaged with or locked to said platen shaft in any backward turning movement of the platen. .It, will be apparent, moreover, that the platen "will be free to turn forward, or in the paper feeding direction, at any time and that after the forward turning movement of the platen has brought the cam projection J in poition to act on the arm I and 'thus disengage the pinion from the platen shaft, further forward turning movement of the platen may continue indefinitely without effecting any movement of the wheel J, but,'u on any backward turning movement of t e platen shaft, the pinion will be immediately locked to said shaft and such backward turning movement will be transmitted to the wheel J, which latter will turn iii a direction to carry its top portion backwardly or toward the rear of the carriage. such backward turning movement of the wheel J is employed to indicate or measure lhe extent to which the platen is required In the operation of my device,

J of the wheel J is mounted on a hose-plate L which is dctuchably serurcd lo the end frame plate B of the carriage, in order to facilitate the attachment of the indicating device to and its removal from the machine.

In connection with the gear wheel J. arranged to be tnrncdhy its grin-ed connection with the platen in the lmrlnvurd turning movement of the latter as described. means are provided for ndicating to the oprrator when the platen has been turned lmckwardly the desired extent, or, in other Words, when the backward turning movement of the distance through which the platen is turned backwardly.

As shown int the base-plate L is elevated part or rib L,

be accompanying drawings,

' t which is located closely adjacent to the, inner face of the wheel J and in which are formed a series of holes k arranged at lme space '-distances apart and adapted to receive a stop pin K located in position for contact therewith of the arm J of the wheel J when saidarm swing s rearwardly in the backward turning movement of the platen. Said elevated parts L of the plate L is also provided with a scale M marked to correspond with line space intervals of the platen. Said scale M may be used in connection with the adjustable stop pin K to facilitate the placing'of said stop pin or, if an adjustable stop he not employed, the operator may determine the distance through which the platen ment of the arm J along;

' in Fig. 3.

is turned ba ckwardly by observing the moveor over said scale.

N indicates a 'mova le stop or catch mounted onthe gear wheel J and adapted to be moved into position for engagement with the top snrfaceof the arm I at the time the cam )roject-ion J 3 is engaged with thesaid arm and the pinion is held in disengaged or unlocked position, as shown Said movable stop or catch is shown as having the form of a sliding bolt or bar mounted in guides on the outer face of the arm J 2 of the wheel J and which .iS.

movable endwise or in a radial directioh'so' that its outer end maybe engaged with or;

withdrawn ;from the arm 'I. n t'he'par- 'ticular construction shown, and as s'een'in detail in Fig. 9, the sliding stop N is provided ,on -its inner face with two notches 'n n ada ted to be engaged by a leaf spring N whic is secured at one end to the inner face of the wheel J and extends through'a said 'notches n n/h- Said notches are-jmade of ii-shape so that thes ring will be readily therewith an ofthe fin r. Said spring holdh theistgpyieldingly" "are shifting or. moving gamesamma sto N is advanced to io'rward position a line space mtcrvab' of 1 provided with a curved i the outer face of V r I disengaged there- I from when" the stop is moved endw'ise fb en a ges the topsurface -01 the emit, as sho wnfin- F-ig. e, 1

said arm and the "ear pinion 1 will be held from'turning with the platen shaftin the bm-lnrard turning movement of said shaft, through the frictional connection of the pinion with the shaft aii'orded by the sprin 1 I, aiid the disengagement of the/arm I rom the cam projection J in such backward turning of the platen shaft will thereby be prevented. The movable stop N, therefore, constitutes a means by which the pinion may be held or locked out of engagement with the shaft, thereby throwing the indicating {device entirely out of action leaving the shaft and platen to be turned freely in either direction without producing any operation of said indicating device.

The purpose of the paper movement indicating device above described is to indicate to the operator the extent of backward turning movement of the platen required when inserting sheets on which bills or invoices are to be printed where it is desired to make out a number of bills or invoices and to make carbon copies 6f the same on a single strip or long sheet of pa er. In a case of this kind it is dcsirableit rat the carbon copies on the record sheet should be spaced as closely together as possible, but atv uniform distances apartor with equal spaces between the several carbon copies. The line space to enable the operator to readily insert new sheets for each separate bill or invoice in such manner that'the first printed 'line of each carbon copy shall be located a desired distance of one, twoor more lin spaces from the last printed line of the precedingcopy. Assuming that the record stri and a sheet of paper for the original biil chinetogcther with a carbon sheet between them, the first bill or invoice may be printed and carbon copy will be made in the nsnaL manner on the record sheet. The printin r j of the bill or invoice havin v been complete the same may be removed ir'o'm' the machine by releasing the guide rollers from the platen by the lever G, or otherwise, and this will he done with-out disturbing the osition ot' the record and earbcnsheets. he platen will then belturned backwardly,"carrying insertion ofthe new'invoice sheet, and the wardly must be such that whenthe new -in'- 'voieestieet is inserted thepart. of the new sheeton-which the first line is'to be printed 'willbe located at such distance from thelast line ofthe carbon copy as to leave the de-' sired s aice between the co 'i'es. ,In using first ,bill'orinvoice ltnsbeen rinted and re- ]moved from the machine, wit: out disturbing the-record and-carbon'shee ithe p'rintin of the firsfliinvoiceWyill' 'aceomplishe I, .--s w EMT 4 ms.

tit)

usually when the gear pinion I is locked in its disengagedhposition by the use of the movable sto) as shown in Fig. 3, and said stop will be shifted backwardly to free it from the arm I after the completion of the first invoice. The platen will then be turned hackwardly, the first part of the backward turning movement resulting in the pinion I bein rotated with the platen shaft, by means 0 its frictional engagement with the same, until the arm I is disengaged from the cam projection J" when the pinion will become locked to the platen shaft. As the backward turning movement of the platen continues, the gear wheel J will be turned until its arm J strikes the stop pin K which is located in position to stop the backward turning movement of the stop at the desired point, or if the scale M alone be relied upon, the platen will be turned backwardly until the said arm reaches the desired position upon the scale. Upon the completion of the backward turning movement of the platen, the new invoice sheet will be inserted and the platen will be turned in a forward direction to feed the invoice sheet, together with the record and carbon-sheets, into position for printing the first line upon the new invoice sheet. As

the platen is turned forwardly the gear pinion I will turn with the platen shaft until the invoice sheet is brought into position for the printing of thefirstdine thereon, at which. time the cam projection J will come into contact with the arm I and the pinion l' will be thrown out of engagement with the platen shaft. The printing of the second invoice sheet may tien he proceeded wlth without any movement being given to the gear wheel J. As soon, however, as the priutedinvoice sheet has been removed, and backward turning movement given to the platen. the gear pinion will be againithrown into engagement with the platen shaft, and a distance through which the plated must be turned backwardly before the-next new invoice sheet is inserted will he measured or indicated as before.

The distance to which the platen must, in any particular instance, he turned backward before inserting an invoice sheet varies according to the distance necessary to be left on the invoice sheet from the topof the sheet in the first printed line thereon. and the distancc to-he left between the carbon copies on the record sheet. tcrlnined when changing from one style of invoice sheet to another either by experiment or by noting the line space distance that the platen must he turned backward before a new sheet is inserted in order that the new sheet. when fed forward in position for printing the first line thereon. will have such relation to the record sheet that said first line will be at a desired number of hue This distance must be de,

space, intervals below the last line of the pre-. ceding carbon copy on said record sheet.

The operator having ascertained the number of line space intervals through which the platen must be turned backward for an invoice sheet having a certain width of heading, places the stop pin K in the desired hole k, in case the backward movement of the platen is to be arrested automatically at the desired point, or if an adjustable stop he 7 5 not used, the operator turns the platen backward until the edge of the arm J reaches the mark on the scale corresponding with the predetermined number of line spaces through which the platen is to be turned backward. He then inserts the new invoice sheet and turns the platen forward until such invoice sheet is brought into position for printing the first line thereon.

.While the pear wheel K is shown as having gear teet 1 extending around the entire circumference, yet the said wheel, in fact, is not adapted fo'r making a complete revolution so that it in effect constitutes a gear segment or curved rack member which may be of any desired length according to the maximum distance through which it may be desired to turn the platen b ckward.

The pinion I is shown as mounted on the platen shaft, but the same result will be produced if thesaid pinion be mounted on another shaft which has turning movement to correspond with that of the platen or platen shaft.

While the rack member heretofore referred to is shown as having the form of a curved rack or gear segment having oscillatory movement about a pivotal axis, 'yet it is to be understood that the rack member may he of other form and otherwise movably mounted so as to have endwisc. movement in such manner that it may be moved backward and forward by the action of a gear pinion thereon, and my invention includes such a movable rack member constructed and arranged as shown or otherwise. It is also to be understood that my invention, in its. broader aspect, includes a line space. indicating device which is operated by the turning movements of the laten, and which includes means operated by the turning movement of said platen in one direction for throwingth indicating device out of action, so as to leave the platen free to turn or rotate in the usual operation of the machine. and I desire to cover a device embodying these general features, without limitation to the specific featntjegspfconstruction illustrated and hereinbe r dcscribed.
