Specification of Letters Patent.

Patented Feb. 18,1913.

Application filed April 25,A 1910. Serial No. 557,330.

To all whom t may concern.'

Be it known that I, VILLIAM J. NnIDrG, a. citizen of the United States, residing at Madison, in the county of Dane and State of IVisconsin, have invented certain new andV useful Improvements in Type--Vriting Machines, of which the following is a specification. p

I Certain principles and features of my invention as described herein are included within the generic vinvention which is described and claimed in my co-pending application filed April 20, 1908, Serial No. 428,212.

The objects of the invention as the same is more specifically illustrated in the accompanying drawings are, first, to indicate to the operator the distance to the bottom edge of his sheet from the current printing position, and this line by line and automatically, irrespective of the lengt-h of the sheet, and beginning a considerable distance from the end of the sheet; second, to give the operator a visual signal upon his nearing the end of the sheet, and this automatically; third, 'to supply him with a signal, preferably an audible signal, automatically, upon his bringing a Vpredetermined point upon the sheet into the printing position; fourth, to render the machine inoperative upon the completion of his predetermined last line, also automatically; fifth, to release the machine for further printing upon running out the completed sheet, automatically; sixth, to enable the operator to release the inoperative machine for further printing upon the sheet being printed, at will; seventh, to supply certain means adapted to make the invention more effective in its application and use, as hereinafter described; and eighth, to supply certain means adapted to be applied to other sheet-n1ovement-indieating uses of the same general character.

There is to-day no device upon the market to tell the operator how near he is to the bottom edge of his sheet until the edge itself comes into sight. I supply him with a practicable system of signalsl to prevent his over-running his page upon his desired bottom margin, In addition I indicate for him the extent of the unused space left upon the paper sheet, beginning long before the time to remove it, and continuing to the very end, so that he can look ahead and tell whether he has room on his sheet for a group of matter like a footnote, or a table, or a chapter heading, or the complementary close and signature. of a letter, that cannot well be divided, and thus can stop his page in advance of the predetermined `pagelength if need be, and this without preliminary care on his part. This function has never before been performed, but is novel to my invention.

I attain my several objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an end view of one embodiment of my invention; Fig. 2 is a detail view of certain parts; Fig. 3 is a top or plan View of certain portions of Fig. 1, with parts broken away to show the mechanism for frictionally connecting my indices with the platen; Fig. 1 is a view similar to Figi 8. but shows a modification having the frictional connecting mechanism transformed into a lateral clutch mechanism by the locking action of the adjunct latch 115; Fig/5 is a front view of a portion ofFig. 1, in vertical section on the line B B; the bell signal being omitted.

and 29; Fig. 29 is a view in section on the line D D of Fig. 2G of the same parts in a second position; Fig. 30 is a view illustrating a further modification in the form of my sneet-controlled elements; Fig. 3l is a diagrammatical representation of another form of decreasable frictional connection between my indices and the platen, together with a more direct form of sheet-control therefor; Fig. 32 is a view showing my indices differently stationed on a dial and having an ad-V justable frictional connection with `the platen in a still different form; Fig. 33 is a topview of the same with certain parts removed; Fig. 34: is an end view, with the plate 11b (Fig. 35) removed and the carriage frame and frame extension' indicated in dottedoutline, of a desirable simplified modeation when the full friction-decreasing and drum-detaining mechanism shown .in Fig. 3 is not required; Fig. 35 is a View in cross section of the same; Fig. 36 is a view in cross-section of a portion of Fig. 37; Fig. 37 is a view of a modification containing a still simpler frictional connection between my indices andthe platen; and Fig. 38 represents a porton of a modified form thereof; t i Similar symbols of reference refer to similar parts in the several drawings.

The embodiments of my invention which are shown and described herein comprise a series of operative indices adapted to indicate progressively withinftheir range the extent of the remaining unused paperand Vhaving a connection with the platen thatnormally causes them to move with the platen but permits them to be detained or stopped independently of the platen, a detaining means to stop them in a suitable initial or starting posit-ion, and a releasing means to release them at aA constant point in the progress of the bottom edge of the sheet so that they'may resume their movevment with the platen. Added to these in- 80.

dices are' various signaling and locking means, together with other accessories intended to make the invention more useful, or more readily applicable to different ma-' chines under varying conditions of operation; v-

rl`he embodiment of my invention shown 1n Figs. 1 to 11 is described as follows: The

lcarriage frame 12,'carried in the usual man ner upon the main frame ll of the typewriting machine, has journaled in its ends disk 11b, attaching it fixedly to the platen by means of screws 103 (Fig. 6). Against this part 11b is placed the friction washer 11, made preferably of a material like leather, and against the washer is placed another friction-disk 11, shown separately inFig. 7, supplied upon the outer face thereof with the annular interdental depressions 51. I next mount upon the arbor 13 a composite part consisting of the bushing 42 and the drum 6, the drum being fixedly attached upon the bushing and forming in effect a single piece with it. The drum bears in a peripheral trough the annular band (Sab, which preferably is made of a material having small inertia, like paper or thin celluloid. vThis band can be adjustably moved upon the drum,having a frictional connection therewith; and it bears upon its surface indices and certain other markings, asy

will be hereafter explained. The adjustment provision is intended to add to the use-` fulness of the invention, but it is not an essential part thereof. f

With the drum I combine the following features: The bracket 100, located within the inclosure of the drum and attached to the outward shell-wall thereof by rivetsr 102,

has fastened upon it the radially-disposed shouldered pin 53 by means of the nut 53". .,''ournaled upon this pin is the hub 88, from the lower portion of which radiate in differ- 6, adapted to engage with the interdental depressions 51 in the disk 11, and thetaillever 54, Fig. 3, engaged by the spring' 7, which is more clearly shown in Fig. 11.

los

, ent directions the lever-tooth 52, Figs. 3 and This spring is attached by one end to the t wall of the drum by means of the screw 9 and the adjusting nut 9, Figs. 3 and 11, and it acts through the engagement of the other end with the tail-lever 54 to press or actuate the disk 11 upon washer 11a and upon disk 11b, the said parts engaging through friction surfaces thereon so as to give a frictional connection between the .drum and the platen. A bend in the intermediate portion of the spring .7 makes contact with the outer wall of the drum, the said wall serv ing as an abutment from which the spring reacts. By turning the nut 9 the tension of l the spring may be changed. Other forms of spriiiginay be used in securing a frictional connection between my indices and the platen, as for instance any one of the i springs shown iii Figs. 18, 31, 34, 35, and

38, or a spring may be dispensed with and the fr'ctionfbe secured without it, as shown in 25,`32,.33, 38 and 37. lido not limit myself with respect to the form of the` spring, or With'reference to the other means of adjusting the friction to increase or` decrease it, and may dispense therewith. The

. friction may be other than a lateral friction, as shown in Figs. 25, 31, 32, 36, 37 and V38.

y end 14. In order to return thislevervS l `into -itsopera'tive position, Il provide the contracting spiral' spring98 having one end thereof 'engaged'w'ith the said leverand the other end attachedto one of the walls of the drum, and thelever isr formed with the slot..

97 to work over the vstop-pin 93 on the lever 92, the said spring op'eratingtohold one end of said slot against the said stop-pin with any desired firmness. An opening 7 6 in the inner Wall of the drum permits the play of the projecting parts 52' and 14, while the opening 75 in the outer Wall of the drum permits the play of the frictionfshoe 96 and the parts bearing it. To cooperate With'the friction-Shoe 96a in a detaining action described later, l place upon the carriage frame 12 the extension 99, bearing the fric tion-surface 99a. The Washer 1 73, Fig. 6, on the arbor 13 holdsl the drum in an operative position laterally. j j

I attach to the carriage frame 12 by means of the screws 6l the frame extension 22,

' Figs. 1 and 10, bearing the inwardly projecting axle 20 (see Fig. 10).' Upon this axle is lournaled the hub or sleeve 21j, bear ing the lixedly attached lever 7 4, the i'iredly attached piece 59 with its projecting stop` pin G2, the fixedly attached collar 105, and

the fix'edly attached lug-piece 17. Jouriialed upon the hub or sleeve. so as to turn freely thereon is also the stop or lever 15 with its lug 63, the said lug bearing up- `ivardlv against the before-mentioned stop edly thereon is to permit of a backing-up movement of the projection 14 when the platen is turned backwardly, as in backingup the sheet," the stop 15 lifting idly upward out of the way iny such a movement, land then returning into position through the force of gravity. I do not limit myself lo this particular means of providing for such a'backing-up movement of the proj ect-ion 1l past the stop-lever 15. The stop-lever 1:5

adapted toiact as a stop upon the projection 14, and it has a distinct lever function as Well.' Through it the projection 14 controls the position 'of other parts, and is not merely fr controlled by them. plained, the' normal yposition of this lever or stop 15 `is in the path of the projection 14, and it is supplied with means returning it into such` position. I do not however confine myself in all casesto the-use of a stop having any 'particular special chai-acteris'tics.

The part-s upon the `sleeve or hlt-1b 21 are returned into-operative position bythe' acf tion chiefly of thenspring 111, Figs. 1 and 10, which is attached at one end to thefranie v12; by the pin 112 and at the other end engaged with the lever 74, the said'lever being normally held against the stop-pin 113- on i the frame extension, 22 `by the pulling action of the spring, and kthis-more or less firmly according'as the leverage is increased or diminished by engaging the spring with the lever 74 farther from or nearerto the hub j" 21. The Weight 66 also assists infthis returning function. A. second function of the spring is to pull baclrivardly againstthe aotion of the projection'll- 'upon the stop 15, j

so as to subtract from the pressure upon the sheet. The Weight 66 also serves this func'- tion. The action of the parts thus far described is controlled by the sheet, through the `following `structurer- At the end of the sleeve l ent the paper-freeler cannotiooniplete its` movement but is stopped by the sheet. but when the sheet passes on the paper-feeler is left free to complete its'movement into a slot el, Fig. 1G.`in either a papeutablo or a piece applied thereto: The preferable form of this paper-feeler is that shown in Fig. l, in which the part 28. journaled on the axis 20 and bearing the pin 23 and the stop-pin 2l, has journaled upon' the said pin23 the /papei-eiigaging portion y2S, the'l'ugl' thereon engaging vagainst the stoppin 24's() as 'to form alone-nay flexion means, or 'knee'joint The purpose of this joint 'is to provide vfor a backing-np movement ofthe shoetibut it is to benotcd that the joint mayl'icriunittcd, as'A ing the operativeness of the invention. rIhe eccentric weight G6 is connected with the paper-feeler in order to return the latter into the most convenient operative position, out of the way of the entering sheet, as shown in Fig, 1. The paper-feeler is operatively ccnnected with the stop cr lever 15 through the stoppin 3G, Fig. 10, on the said weight, and the lug 17 cn the hub 21. The essential features of this portion of the mechanism are the paper-feeler, its axis, and the lever or stop 15. It is possible to omit the intermediate stop-lever 15 and the separate axis 20, by placing the paper-feeler upon the same axis with the platen and giv-y ing it a path intersecting the path of the paper vsheet direct, as shown in Fig. 31. I do not regard my invention as limited to any particular form or forms of paperfeeler, nor to any particular position therefor, nor to any particular manner of connecting the paper-feeler to act controllingly upon the indicating means employed.

In order that the paper-feeler may move in a path intersecting the path taken by the sheet in cases in which the invention is applied to machines in'which the paper-table S is unprovided with the slot 4 shown in Fig. 10, I attach upon the paper-table 8 the piece S', Figs. 1, 8 and 9, containing the slot 4. This piece is shaped to hook around the rear edge of the paper-table, and its slotted portion lies upon the paper-table as indicated in Fig. 1. The piece 8 is secured in place upon the papentable by means of the set-screw 80. Other forms of slotted plates or auxiliary paper-backing that may be used with suitable forms of paper-feelers in such cases are illustrated at 82, Figs. 26, 28, 29, and at 8g, Fig. 80, described later.' I do not limit myself to any particular manner of providing for the action of the paperfeeler into the paper-path. The paper-feeler I can be made to operate from underneath the sheet just as well, as illustrated in some of my gures.

Afirst it rotates step by step also.

The mechanism described automatically brings the paper-feeler into an operative position permitting the introduction of the sheet, without interference, a function that I believe no signaling mechanism employing a paper-feeler in connection with typewrit ing operations has before performed, but that is novel to my invention. My backingup provision is novel also.

The action of the structure thus far described is as follows: The sheet of paper 45 is entered into the machine in the usual Way down the papentable 8, advanced in usual manner into printing position, and printed line by" line as usual, the platen carrying forward the sheet in the usual and well-known Way. As the drum G is connected fricticnally with the laten, at Jventually however the projection 14 meets the lever 15 in its path. At rst it pushes this lever idly ahead of it, imparting a turning movement to the hub or sleeve 21 and moving the paper-feeler 28 in the arc 101, Fig. 1. It will be seen that if the paper sheet were not present, the end of the paper-feeler would continue on into slot 4 until the projection 14 cleared the lever 15, and the drum 6 would continue its movement with the platen. But during the presence of the paper sheet over slot 4 the paper-feeler cannot thus enter the slot, but is stopped by the sheet. The lever 15 thereupon becomes a detaining stop in the path of the projection 14. By this time the friction-shoe 96a has been carried fo-rward opposite the part 99 on the carriage frame. A further movement forward of the frictionally con nected drum 6 mustresult in a turning of the lever 95 upon the pin 94, thus driving out the shoe 96a against the friction-surface 99a. The resultant friction will at once act detainingly upon the drum, so that thereafter less force than before Will be required to stop the drum against the forces tending to rotate it. The stop 15 will also act detainingly upon the drum. But meanwhile another action is taking place, the pressure.

of the shoe 96a against the part 99 under the leverage of projection y14 resulting in an inward pressure upon the end of lever 92, thereby opening up creasing the friction between the the acticn'of spring 7 That is to say, the friction between drum 6 and the platen is regulated under the control of the sheet, varying accordingly as pressure is exerted upon projection 14 by stop 15, such pressure being increased to a controlling extent during the cont-rol by the sheet of paper-feeler 28. These agencies acting together are calculated to detain the drum with the miniagainst stop 15 and conthe sheet, and that is my purpose in using all of them. And as the spring 111 acting upon the lever 74 adds still another means of subtracting from the pressure of the paper-feeler against the mum of pressure sequently against vsheet,.I have a mechanism adjustable with the greatest delicacy and snreness to any conditions of service that may arise. My drum is now detained or stopped, and it will always be stopped, necessarily, with the same point on its periphery opposite the pointer 34. This point may be indicated by the small circle or index 89. In this position it remains during the presence of the sheet. Eventually, however', the sheet is advanced until the bottom edge thereof passes the paper-feeler 28. Instantly the paper-feeler enters slot 4, stop 15 ceases to act detainingly upon projection- 14, shoe 96a -is withdrawn by spring 98 from contact 'with the controlling partv 99, and the 'drum and the platen againstfriction between the platen and drum 6, spring-actuated by spring 7, and no longer controlled or regulated by the sheet, becomes of its original force, insuring the simultaneous rotation of the drum with the platen. It is clear that as the sheet is further advanced, drum G will be advanced cordinately therewith, and that symbol S9 will be advanced away from pointer or index 3st and another peripheral point be broughtl opposite it. This point can be marked to indicate the distance remaining from the printing point to the end of the sheet, or to a point a xed distance therefrom. That is to say, if the end of the sheet seventeen line-spaces distant from the printing point at this moment, I can niark in v periphery 1T to indicate this distance, and after another advance I can'mark the new `point on the periphery 16 to indicate thelnew position of the sheet-end relative to i the printing point, if the distance ,be sixteen line-spaces, and so on during the remaining progress of the sheet. I prefer to use indices involving no mental calculation nor memorizing on the part of the operator, suoli as the series of descending numerals shown. and I prefer to use the line-space as a unit of measurement, but my invention is not dependent upon the use of any particular kind. or number o-r order of indices.

lt is to beiioted that the mechanism described can be backed-up from any position of the sheet and to any required extent; the knuckle-joint construction of the paperfeelerv and the one-way stop provision in' connection with stop-lever permitting free backing-up of both sheet and drum.

ilfljimcs. The mechanism described can be used upon the mostl delicate tissue fabrics without danger of injury. A mechaiiisinof suclrdelicacy of adjustment will ,not always lie needed, and indeed upon cerl tain classes of work could not he used to the ,best advantage. For the purpose of siiup.i fying the action of the mechanism I desire to show means whereby certain of the elev inentsshown as cooperating may in effect be eliminated, and the mechanism used with- To this end I out them, and this at will. place upon the outside wall of the drum e the lock-piece 16, Fig. 3, shown by dotted lines, in Fig 1, "pivoting the saine stiliiy upon thepin 18 in such wise that it will retain any position given it. This piece when moved toward the periphery of. the drum lies. away .from the lever-end 14', -but when shifted toiivard the arbor of the drinn it lies against thesaid lever and locks it, thus prevent'ing the action of the leverswit-hin the drum, "Whenr thus locked the projecting lever-endif acts as 'a fixed projection carried byhthedrum, and the connect-ion between the drum and the platen isa simple sirable.

frictional connection. The action is the same, essentially, the difference being that there is no easing'of the friction between the platenand the drum, and no cooperation of the part 99 in detaining the drum, the entire work of detaining the .drum falling upon the lever 15. I show modifi-catioiisof this simpler combination of elements iii certain of my figures. I also wish to provide means whereby the operator may at will secure a more positive connection with the platen, as for instance when tliesignaling oi' locking mechanism requires greater power to operate than is afforded by the frictional connection, or when for other reasons a more positive connection with the platen is de- To that end I supply the periphery of the disk 11 with one or more pivoted latches 115, t-he same being pivoted at one end upon the pin 116, and at the other end having a projection adapted to fit into the depressions 117 in the periphery of the disk 11b. These latches are made preferably of a resilient material, and are shaped conveniently for manipulation. Their purpose is to furnish a means of locking the disks 11 and 11b together so that they will turn as a unit. W'hen this is done, as shown in Fig-4, the frictional connection between the platen and the drum G is in efiect'eliminated. As the tooth 52 is able to lift entirely free ofthe interdental spaces 51, and under the pressure of the. lever 95 upon the lever 92 will always so lift free when the. said disks are locked together andthe leverend 14 is pressed against by the obstructing stop 15, I have instead of an easable frictional connection a releasable lateral tooth/ed clutch connection between the drum and the platen. The lock-piece 16 in this use must of course be shifted aside so 'as not to interfere with the action of the le\ c1295.

Other 'indicating nimmt-In connection with in v indicesI employ certain signaling and locking devices to notify the operator of the approach of the bottom edge of the eral sections in such a manner as to forni a striking contrast one with th other, the one preferably being colored white with black indices thereon, and the other, 6, preferably being colored a solid black. By attaching the combined shield and pointer 34 as shown, I conceal .thev section bearing the indices 6 from the eye of the operator during its period of rest, and then brin it into sight, along with the indices. This furnishes me with a very perfect signaling means, the

Ilsupply' 'it 'the eo tract-able stop 96c the lever 952L having the stop 96e, and instead of bringing my levers into action primarily through the coperation of the lever 15 with the projecting lever-end 14a, the primary action is the action of the stop 99c upon the stop-lever 95d.l 96e. This action pushes the projecting leverend 14a against the'lever 15 until the paperfeeler 2S is vstopped by the sheet; after which the detaining and opening action of the modification is likethat of Figs. 12 and 13.

Fig. 15 is a view showing how the lever 95, together with the detaining part thereon and the cooperating part 99 on the frame, may be omitted, the lever 92b itself being shaped to form the projection 141. In this .modification the lever 15 acts more directly upon the projecting lever-end 14b to open the friction between the disks 11 and 11b and to detain the drum 6.

F ig. 16 is like Fig; 15 in structure, except` modification the cope'rating part 99 on the frame is retained, but changed slightly in form. The spring for the friction is changed also in form. Part of the structure involved is shown in cross-section in Fig. 18. The armed dished spring 7 holds the drum frictionally against the friction-disk 11b through the agency of the sleeve-washer 106, upon which the drum is journaled to'turn freely. The pressure of such a spring can be adjusted if desired by means of the washer 107: a simple" substitution of a thicker or thinner washer will accomplish this adjustment. The leve-r 95c is attached to the drum by means of the axis pin 94 in a manner similar to thatl already described. This lever terminates in a frictionshoe 96, adapted to cooperate with the friction-surface 99d on the part 99. The action is as follows: The projecting lever-end 14S. pressed upon in effect by the lever 15, operates the lever 95 so that the part 96d pushes inwardly upon the outer surface 99l of the part 99, which action has both la detaining effect upon the drum and also an opening effect upon its frictional connection with the platen, the drum bein lpulled outwardly away from the frictionisk 11"` by the leverage exerted upon thel pin 94.' In other respects the-action of this modification is the same as has been described. j Y

Fig. 18 is like Fig. 17 in every respect, exfcept that all the levers within the drum are face'SO. The action of these beveled faces tends to push the drum outwardly from the friction-disk 11b, thus 4opening the friction, and at the same time a. detaining action upon the drum is exerted. In this respect the modified mechanism is the equivalent of portions of the mechanism. already described. It is possible to omit the beveled faces from this modification, in which case the co-action would vbe merely a stopping action, like that of Fig. 1 when the projection 14 islocked bythe latch 16, with no easing of the friction, the omitted# elements in thisv case corresponding to the eliminated elements in that.

In Figs.. 19 and 20 the arrangementy of parts is like that shown in Fig. 1, except in the sheet-controlled elements, some of which,v

shown in Fig. 1 are here omitted, and lthe rej' mainder of whichare stationed under the platen instead of lover the papertable., The

frame extension 22a bears the inwardly project-ing axle 20E1 with its hub 21a. kUpon the hub are stationed the xedly attached lever 15a, the' fixedly attached paper-feeler 28, and the ixedly attached weight 66a. vThe platen isvsupplied with the `circuu'iferential slot or groove 4 near the end, just beyond the i orking surface. u The paper sheet overlaps this slot, and', upon the passing of the end thereof the .paper-feeler enters it, the function of the slot being exactly thatof the sloty 4 in Fig. v1. And when the projection 14 clears thelever 15a, the parts automatically return into operative position, under the influence of the weight. A backing-up movementof the projection 14 results in'an idle turning backward of thehub 21EL upon the axle 2Oa in this arrangement, so that certain one-way flexion means shown in some of my other gures are not needed.

In Figs. 21 .and 22 the freely revoluble drum 6 bears the peripheral indices 6EL and.

the other signaling markings as before described; and it bears also the weight 25,'-

adapted to bring the indices into a suitable starting position when the drum is released, from connection with the platen. vAt a moment determined by the paper-feeler 281 this drum is connected 'to rotate with the platen. The paper-feeler here is provided'as before with a one-way flexion means', so that it will push idly backward before a backing-up bottom edge of the sheet through and out of the slot 4 in thepaper table 8,v without disyturbingthe position of the arm- 11.9b bearing 1t.` The structure is [as follows: 'Jourr naled in the frame-extension 124' upon the lever 118 and the arm 119D.

Vvsa

frame 12 is the axle 125, having fixedly attached thereto at one end the lever 126, and Xedly attached at the other the thumb- `The lever 126 carries the pin 128', upon which is journaled the friction-roller 127 adapted to make contact with the outerside ofdrum 6. The arm 11911v carries the stop-pin 24", and the paper-feeler 28bwhich is hun on the pin 23b and the movements of whic 4are limited in one direction by the stop-pin. It also carries the pin 121, upon which is journaled the eccentrically balanced or weighted piece 122 having a segmental periphery 123 adapted to rest upon the surface of the'platen. When a sheet is to be entered into the machine the operator presses downward upon 'the lever- 118, thus raising the'paper-feeler 28" from its slot and raising also the. arm 126`bearing the friction-roller 127; The result is that the drum 6 is released from its frictional connection withthe platen. By this action the piece 122 is alsoV lifted clear and falls into position as shown.' The operator can at once release the thumb-lever, for the.

piece 122 will now rest with its periphery upon the surface of the platen and hold the paper-feeler sufficiently clear of the paper table topermit of the easy introduction of the sheet. The sheetis now inserted, the platen turned forward, and, the end of the segment 123 being reached, the paper-feeler will be lowered upon'the sheet, which thereafter controls the position of the parts involved. lVhen the end of the sheet passes from under the paper-feeler the arm 119b is lowered,vv thereby pressing the friction-roller 127 againstthe drum 6 in such a manner as to force the," drum against the frictionwasher 11atv at the end of the platen, thus connecting the drum with the platen. From now on the action of the indices 6a will be as has been described. In this figure I show indices intended to indicate the distance to the bottom line of a page that ends (say) five lines from the bottom edge of the sheet, instead of to thebottom edge itself.

Figs. 23 and 24 illustrate another arrangement of my sheet-controlled elements, the indices and their connection with the platen being that shown in Fig. 1, but the paperfeeler28c being stationed to work from underneath the sheet upward, instead of from above the sheet downwardl The structure is thisThe frame extension 136 bearsthe inwardly projecting axle 20C, and also the inwardly projecting plate 82, the plate lying above the paper table 8 at a distance convenient for the ready-insertion. of the paper sheet between the two, and containing` the slotoropening 4. The axle 20c has journaled upon it the hub 21c -bearingfthe fixedly attached lever or arm "119, which is vstationed to lay` past the end of the paper table-8, and'in its normal .depressed position meshes rests upon a fixed stop-pin 134. This arm in turn bears the inwardly projecting pin' 23C, upon which is mounted sleeve 21d carrying the paper-feeler 28 and the weight 66g to restore the paper-feeler to operativeposition, the two being attached the one to the other. To limit the movementof the paper-feeler inthe onedirection, the arm 119c bears the inwardly-projecting stop-pin 24C," againstl which the weight 66c engages, the purpose of the arrangementbeing as before to furnish the paper-feeler with a one-way flexionmeans for use in a backingup movement of the sheet. As before, the lever` l5c is loosely journaled upon the hub 21; and it isprovided with the lug 63c to engage against a second stop-pin 62C' on the arm 119C, the purpose whereof is to provide it with a one-way flexion means so that the projection 14 may be backed up past it, the lever 15c lifting idly backward in such an action. The hub 21c bearsalso the fixedly attached lever 7 4, and the frame 12 the inwardly-projecting pin 112C, between which the spring 111c exerts an adjustable pulling action, in order to counteract more or less completely the weight of the lever 119, and its attached parts and in this way to regulate the pressure of the paper-feeler Iupon the sheet. The paper table 8 contains the opening 133, through which the paper-feeler 28c may play 4against the sheet, and when the sheet passes on, into the slot'4c in the plate 82, above the sheet.

In Fig. 25 my indices are carried upon a belt 6e running over t-he driving pulleyr 112 attached to the platen, and a second pulley 153, the belt having up'on it the project-ion 14e to coperate with the lever 15", and through it with the paper-feeler28e. The lever 15e is supplied with the weight 146 to restore it into operative position, und with the pin 63e to engage upon the arm 147 in a one-way ieXion means. The indices 6a may be duplicated upon the belt if desired, and the projection 14e duplicated, as shown, for use in printing small work. The sheet-controlled elements are described thus: The frame extension 22e bears the axle 2()e fixedly attached to which are the crank-lever 150 and the paper-feeler 28e. The rod 14S) furnishes a connecting means with the lever 15" as shown, in consequence of being connected at its upper end to the arm v150 and at its lower end t-o pin 148 carried by arm 147. The action of the paper-feeler is substantially as before described, except that. instead of swinging lin a direction opposite to that of the paper sheetas in Fig. 1 it swings in a direction following the sheet as in Fig. 19. It is to be noted that I omit the one-way flexion means for'the paper-fecler in this'arrangement, andv that the paperfeeler is retracted from the paper-path by the counter-balancing weight of the rod i t and the arms 147 and 150, instead of by the weight 66. It is to be noted also that in this arrangement the friction between the indices and the platen is a belt friction, thatI is to say, a peripheral friction, `the pulley 112 and the belt 6e being the friction members, and what is more, that it is an easable friction, since if the belt is slack the stop-l ping action of the lever 15e upon the pro` jection 14e will at the same time tend to open the friction.

Figs. 2G, 27, 28 and 2 9 illustrate another modication in my sheet-controlled elements, the indices being carried and connected as shown in Fig. 1, upon .the 'friotionally-connected drum 6. In this modification 'the paper-feeler 2Sf is shaped to lie flat upon the paper table under the paper sheet as a turned-in extension of the arm 119i, and the mask or plate 82 has a slot 4f shaped as shown in Fig. v2S to receive it. Figs. 27 and 28 show these parts, and Fig. 29 isa view in section on the line D D showing them in the position they assume after the passage of the sheet and before their return into vfirst position. The secondary axis 23C, stop 24c and weight 66c of Figs. 23 and 24 are omitted, as is the opening 133 in the paper table. In other respects the structure is essentially the same as that shown in Fig. 23, the paper-feeler returning automatically by its own weight into first position when the projection 14 clears the lever or stop 15f, and this first position being such as not to interfere with the entering sheet or lie in.

the way of the operator manipulating it.

Fig. is somewhat like Fig. 26 in structure, except that I add elements adapted to raise and lower the plate Sg from and against the paper table, instead of allowing it to remain stationary. The structure is described as follows: The frame extension 142 attached upon the carriage frame 12 bears the inwardly-projecting pin 144, upon which is journaled the arm 119g, with its turned-in paper-feeler 28g. It also bears the inwardly-projecting pin 141, upon which is journaled the lever 139, the said lever being supplied with the `slot 140, the pin 20g, and the stop 62g. Journaled upon this pin 20g is the piece 15g, bearing through the lug 63g upon *he said stop 62g so as to form in eifect an operative extension of the lever 139 when its free end is acted upon downwardly, but when such end is acted upon upwardly lifting idly aside, the purpose of this structure being to provide for a backing-up movement. of the projection 14, in whose path the piece 15g normally lies. The .lever 119g bears the pin 143, upon .which is journaled the lever 137. This last-named lever carries the pin 138 working i-n the slot 140; and it bears the turned-in plate 8g, supplied with a feeler-receivino' slot or opening.` A spring 111g engaged.J by one, end

with 'the pin 112g pulls downwardly upon the lever 139 as shown, in order to restore the working parts to their operative position. v The action of this mechanism is as follows: The sheet 45 is inserted upon the `paper table 8, the paper-feeler 28g meanwhile lying flat upon the paper table underneath it. VThe sheet is advanced, by rotating the platen and eventually .the projection 14 presses against the piecelg. thereby lowering the plate 8g upon the sheet. Furthery pressure upon the piece 15g tends to raise the paperfeeler 28g against the sheet. When the sheet passes on the paper-feeler passes into the slot in the plate 8g as before, these parts being shaped as shown in Figs. 27, 28 and 29, releasing the vlever 15g' from.A its stopping act-ion. The mechanism now. enters upon its 'indicating action, substantially as described in connect-ion with Fig. Il.

Fig. 31 is a modification showing how it is possible to omit all the sheet-controlled group of'elements except thc paper-feeler itself and the cooperating slotted paper `table; and it also somewhat diagrammatically illust-rates a modification in the form of easable vor releasable frictional connection between the indices and the platen. The disk or pulley 56, attached to turn as a unit with the platen, has extended around its periphery the friction-strap 57, attached at either.. end to the pins 60 upon the lever 32. This lever is journaled upon the pin 53h on the drum G; and it is provided .with a tail 54h, against which presses the spring 5,5, also attached to the drum 6, the pressure of the spring tendingto tighten the strap upon the periphery of the part 5G. The lever 32bears upon its extremity the inwardly-projecting paper-feeler 28, in the path 101 of which lies the slot or opening 4h, in the paper table 8. The sheet` prevents the orbitallymoving paper-feeler from entering the, slot 4h, during its presence over the slot, thus detaining the drum, but. in this case having fewer intermediate elements to work through. Its action is this: The lever 32, in effectpressed backwardly upon its axis 53h, loosens the friction-strap 57, opening the frictional connection between the drum and the platen and permitting the drum to stop independently of the platen; and at the same time the paper sheet acts, through the paper-feeler, as a stopping agent, as it would do if the friction were not supplied with an easing means. When the sheet passes on, the lever 32 is released,the friction-strap 57 is tightened by the spring 55, and the platen picks up ythe drum G with its indices as before. It is to be noted that in this arrangementI the paper-feeler. is ret-urned into operative position automatically, and is removed out of the way of the entering sheet automatically. f

Figs.` 32 and 33 illustrate a modiication 33,5 l element pulling backwardly against the acshowing how my indices Ga may take dial form. and be stationed more conspicuously upon the machine at some distance troni the controlling elements. The trictional connection with the platen in this case is et't'ected by means ot the platen-connected periphery 11i, the di.al.-connected drum 167, and the cord l--fnictionally connecting the twohelt-wise andfguided by 'the interinov w vdiatelylocated-` pulleys 156 and 166. The

lprojection 149 connected with the indices, as beto-re, is engaged by the lever 1.5i, Which, through the shaft crank-arm 148i, and

the rod 149", pinlli and arm 150i.. is connected with the paperdeeler 281 and controlledby it. Thecornhined pointer and shield 34 shown in Fig'bnt omitted trom Fig. 32,y permits of a signaling action las Well as an indicating act-lon, the two sections of the dial, 6a and Gl, beingditerently colored so as to supply a visual signal. The

vaction of the mechanism is essentially the sented in Fig. l, except tor diderences in form and proportion, and except for certain omissions, such as the triction-opening or easing elements, the 'cooperating detaining element on the iframe, and adjustable tion. of the lever 15 to ease the'pressnre upon the sheet, as Well. as other elements as will diminished.

appear. The structure is as :tolloWsi The drinn G, reduced to a mere peripheral sheli having a light ti'iction-tiange, carries the indices and signaling markings, and also the profection lak. On either side of the Flange l place the friction-dish; llaand l1", and against the-,disk 11 the armed dish-'spring 7k, 'and against the spring the circular head piece 1lb" having in the hub thereof the set-` screw 83. These Aparts are adapted to tit over the platen aroor as shown, so as to be' attached againstthe end of' the platen (hy the set-screw; and they/are fastened totether by' the three screws 92 in such Wise hat the spring pressure upon the frictiontlange of the drinn k'can. be increased or This pressure need not however to be adjustable. Upon 'traine-entenzion 22 of Fig. 1, I place the inwardly-pro iecting axle 20, having jonrnaied thereon he papenteeler 28 provided. with Oneway flexion means as shown inv Fig. 1. Also jonrnaled upon this aide is the eccentric Weight 66 having thereon the stop-pin 62 andacting as a imit with the oiece 28 of the one-Way 'flexion means beterel mentioned, and the lever 15 'having' thereon the log 68 to engage against the. said stoppin. The paper table 8 is provided with the slot or opening d, through which the paper-teeler may pass. Tft is to be noted that by using a light drum as shown, light -friction, and a shorter lever 15, the pressure ot the paperinger upon the sheet is decreased until it is suiiciently light for ordinary Work, Without the addition ot the omitted elements. T he ,act-ion ofl this modication is substantially the projecting lever-end' it has been locked by the latch 16.
