At the inner end of said swinging frame is located a transverse p'ulley shaft .30 provided with b'elt pulleys 31, 31 over which are trained the inner ends of the upper carrier belts. vThe inner ends of the lower carrier beltsl are trained over pulleys 32, 32 which are affixed to the said shaft 2 of the machine. The two outer shafts 20, 21 are mounted in bearings 27, 28 attached to the transverse frame bars 12, 12, and the shaft 30 is similarly mounted in bearings 33, 33 attachedto the upper parts of the oblique inner frame bars 13, 13.

laps in contact with each other so that sheets fed between the belts at the outer end of the carrier 4will be conve ved by 'and between the belt toward the machine and delivered to the u per and lower carrier belts 5 and 8 of the atter. At points between the ends ofthe carrier frame, the adjacent laps of said belts are pressed towardy ,each other by means of upper and lower pairs of presser rollers 35, 36, the ends of which are mounted in bearing boxes attached one to each frame bar of the pairs of y intermediate framebars 14, 14.

Devices for driving the carrier belts 5 and' 8 vof themac'hinel and the belts 24' and 25 of the carrier are provided as follows: A rear wheel-40 is affixed to one end of the sha't 2, which is located at the receiving end of the machine and carrying the pulleys over which are trainedthe lower se belts 5 Oftheina= chine andthe lower set of belts 25 of theearrier device, as herembefore described. Meshing with said gear wheel 4() is a gear wheel 41 (Fig.` 3) which is alixed to the adjacent end-ofthe shaft 6, which carries the pulle s vover which are trained the upper set of bets The upper and lower belts are arranged with their adjacent 8 ofthe machine. Near the end of theshaft .6, remote from the gear wheel 41, is a second gear wheel 42 (Figs. l and G) Whichis secured uponthe said shaft\and which meshes with a gear wheel 43 mounted upon a bracket arm 44 which is rigidly sup orted at the upper end of one of the biac iets 3. with the ear wheel 43 is a gear wheel 45 which is a Xed toa shaft 46, said shaftheing rotatively mounted in brackets 47, 47 mounted upon the frame 1 at the rear of the brackets 3, 3 supportin g the shafts 2 and 6. Upon the end of the shaft 4.6, which extends outwardly from the bracket47 and in the same horizontal plane with the shaft 6, is affixed a gear wheel 48 which meshes with a gear wheel 49'carried upoirthe outer end of a shaft 56 which is rotatively mounted' in said brackets 47, 47 and in the same horizontal plane with the shaft 2. Said gear' wheel 49 is driven by means of a pinion 51, mounted upon a stub-shaft 52 located below the shaft 50 and carryingr at its outer end a fixed pulle 53 which is driven by a belt from a line shaft or other driving source.

The pulley shafts 2() and 21, which are located at the enterrer rising and falling end of the carrier frame are provided with inter meshing gear wheels 54 and 55 which act to drive the upper shaft 20 from the lower shaft 21, which is itself driven from the shaft 2 by the lower set of carrier belts.

On the outer or rising and falling end of Meshing l the swinging carrier, and mounted on said carrier, so as' to )artake of the rising and falling movement l which the side margins of the sheets, which are delivered one by one to thek carrier, ma be brought to proper position laterally wit respect to the carrier belts, and also a sheet feeding device by which separate sheets of paper-board or strawboard are taken from sheet of the pile of sheets being delivered to the machine. Said frame, cin-lying the sheet guiding andl feeding devices, 1s cont iereof, are guiding means by strncted as follows: Said frame ern-bracesV two side frame members cach consistingof a horizontel,hlong)itudinal frame bar 60, a de pend ing frame to between its ends and an upright frame bar 62 rismg'froin the rear end of said longitudiaini rigidly attached therc nal frame bar.V -Safidlatcral frame members are rigidly connected vi'th eaclr other by cross ii'ts`63, 64 and.65 Whichcxten'cl horifi Y zontal y between and are rigidly attached to l130 the horizontal frame bar 60, 60 and ai cross f girt 66 attached at its en Ls to the upper ends of the upright frame bars 62. Said upright 1.2 Iframe bars are heldrigidly at right an les to the horizontal'r frame bars 60 b o lique braces 67, 67, while the depending rame bars L 6.1 are held rigidly in position at right angles 1 -ite' the longitudinal frame barsby means of : f'gusetdplates 68, 6 8. The frame made as deis pivotally connected with the outer endfof the carriervfrii-me through the medium 0f the lower pulley shaft 2l at the outer end ofad carrier frame, on which shaft said feed Y fmeaehailiisIn frame is pivotally su ported by 315/,

Moreover, the Ahorizontal distance between. the shafts Zand 21 at-the inner and outer ends of the carrier i fx'ameis the same as the distance between the .frpivots atthe o osite ends of the space rods.

Asa result of t ,1s construction', all lourofthe y pivotal points will maintain positions correlfspondin withthe four angles of 'a parallelo- '45 grarn,'w atever may-be the position of the A fluter end of the carrier' frame, and the horiv`Zontal member ofsaid feed vr'nechanisin frame vwill always be maintained in a horizontal poi veinen, parallel with the sheets of paper on to 1,;neft1nck.

'f In-'forderrthatthe sheets may be placed f and held in a position with their side marm's 'parallel .with the carrier belts, and in y esiredlateral position with resipec't to said '65r outwardly extending portion ofthe bracket are-'secured in the upper end o f the bracketis provided with'slots and isheld against the corresponding portion of the bracket 84- slots being provided in the bracket 85 in order that the guide board may be adjusted laterally for sheets of different Widths. IfI the sheets be fed by hand from the pile, as may be done, the said sheets will be thrust laterally against the guide board and at the same time are advanced untilgripped by the carrier belts. lf the automatic sheet sheets will be carried thereby latere-lll;r against said guide board, as they are a vanccd, in the manner hereinafter described.

The sheet feeding devices embrace feaindicate a plurality of feed wheels, each of which is. provided with outwardly Vproj ecting spurs or points for engagement with the sheets of paper. Each of said' feed wheels is separately mounted in the freel ends of two horizontal links 91, 91 which project outwardly from and are mounted at their inner ends upon the upper ulley shaft 20 of the carrier. Each feed wieel thus mounted is adapted for rising and falling movement athrough the swinging of its supporting links about said shaft 20. As illustrated, each of said feed wheels is securedl to a horizontal spindle 92 which extends through bearing t e end of each of said spindles is a driven sprocket wheel 93 having driving connection with the feed wheel. On said shaft 20 are secureds rocket wheels 94, 94 arranged in the same orizontalplanes with the sprocket 93 andlfi by means of which the feed wheels are drivenfrom the'pulley shaft 20 and turn in the same direction as the belt pulleys upon said shaft. i

Y The links 91, 91 are supported in a substantially horizontal position by a cam shaft 96 which extends transversely beneath the Acentral parts of said links, and is flattened or elliptical in cross-sectional shape. Said cam shaft 96 is rotatively supported at each cndby means of journal boxes 97, 97 which are mounted upon the horizontally extending members 60, 60 of the lguide frame. Upon one end of the said shaft and outside of the frame member' is a lever arm 98 (Figs. 2 and 4). v One end of the lever is provided with an eve for attachment thereto of a cable 99 which is trained under a ,pulley 100 fastened to .the floor and runs backward from said pulley to the delivery end of the -machine Thoother end of said lever 98 is r :vided with a omnitel-weight lOl which normally holds the cam shaft in a position with its long diameter horizontal, in which owcred to bring t efeed wheels into operai .by means of bolts having wing nuts, the

feeding device illustrated is employed, the

wheels 93, 98. Sprocket chains 95, aretrained over each 'pair of sprocket wheels.

tures of construction as follows: 90, l 90, 90

a ertures in the links 91, 9'1. Mounted on v iosition the sup iortingA links 9i, 91 are."

f 45 thereof, after the orward 55- the sheet 1s bein Y tive position. The' feed wheels maymhe' rendered inoperative, by an operator stau tioned at the delivery end of the machine, by means of the cable 99 which operates the lever arm 98 to turn the cani shaft a quarter i of a revolution thus bringing the said cani shaft into a position with the long diameter thereof into a vertical position, thereby raising the bracket members 91, 91 and causing the feed wheels to be lifted out of engagement with the top sheet of the pile. To the end ofthe shaft remote fromvthe lever 98 there is attached a hand Wheel 102 by means of which the said shaft may be turned to either of its twovpositions, by the operator at the feeding end of the machine.

In order to justify the' sheets against the guide board 83, the feed wheels 90 are su g ported at such an angle with respect to t ie said guide board that the sheets engaged by said feed wheel` are carried laterally toward or justified against said guide board and are given proper lateral position as they are moved to position for engagement with the belts of the carrying device; the axis of each of the feed wheels and its supporting spindle being slightly inclined in a horizontal plane, .relatively to the pulley shaft 20, as clearly seen in Fig. 2.'

For preventing the outwardly projecting spurs ofthe feed Wheels engaging more than one sheet of aper at a time there is provided an idler shafli 103 which is rotatably mounted in journal boxes 104, 104 secured to the l horizontally extendingmembers 60,60 of the guide frame and located near the outer ends thereof. Mounted upon the said shaft are two, pulleys 105, 105 which rest upon the uper surface of the sheet pile and support the 40 rame at such elevation that "the spurs on of said pile.

In order that thespurs on the feed wheels will not tear the aper or retard themoticn ortion of the sheet has become engaged witii the 'carrier belts of' the carrying device',v the said feed wheels vare connected with their drivin@ sprocket the feed wheels will engageon'ly the top sheet l wheels'by means of a roller clutc mechanism, which permits the belts to pull the sheet from underneath said feed wheels byallowing the said feedrwheels to turn faster than the driven sprocket wheels, but lock them to the said sprocket wheels during the eriod carried to position or engagement with tfie belts. Said roller clutch mechanism is illustrated in Figs. 7 and Q-of the drawings and is Amade as follows: The bore of the huh of the feed wheel 90 is .en-

,50 largedat the end thereof adjacent to the di'iv'e'nsprocketwheel 93 so that it is .larger in diameter than the spindle 92, and the said hub is provided With a plurality of recesses 110,'11'0, 110 exterior to the enlarged part of the bore. The hub of the driven sprocket 93 edge a stilfening eases? is rovided with a laterally extending i e m lint rie portion 111 which fits and turns in the concentric, cylindric recess in the enlarged huh of the feed wheel 90. Within the ree. l

cesses 110, 110, 110 so formed in thehuh ofk said wheel, are located three cylindric rollers` 112, 112, 11'2 which hearv upon the extending portion 1,1 ci the said sprocket wheel anhand also against the outer walls of the `recesses 110, 110, 110. The said outer of the a higher rate of speed than the drivensprocket wheel 93 the said -eylindric rollers will be carried to the opposite or wider ends of the recesses 110, 110, 110, thus permittinev the said feed-wheel to turn independently of the said driven sprocket. .y

- The sheet feeding vdevice is preferably counterweighted te permit it to be swung from one position to another with the exertion of little'power. The counterbalancing device herein shown consistsof a weight v106 which is connected with the carrier frame by means of a cable 107 trained over pulleys 108,108, and attached to a bail 109 whichis hinged to the transverse frame g members 12, 12 at the outer end of the swinging.

carriere To provide means for separatlng or spreading apart the advance edges of the top sheets` on the sheet stack in case one or more sheets aie draggedforward with the top sheet cngagedby the feed wheels, and for lifting the top'sheet into position for entering between the carrier belts, l employ a pivotallyy supported rocking .guide plate 77 (11 ig. 10).'located in the path of said sheets, in an upwardly and forwardly inclined position, am which extends across the end of the carrier 'frame between thesame and the upper portion of the sheet.

stack. The guido )late 77 has at its upper l'llan fe 78 at right angles thereto. Said guide p ate acts to deflect upwardly the advancing top sheet which passes over the top edge of the same and is provided y on its outer face with broad shallow corrugations which are adapted to severally' -en-v gage 'the forward edges of the yadvancing sheets and spread the same apart in order that not vmore than one of them will pass at the saine time over the top edge of the guide plate, the corrugations having inclined, as distinfruished from abrupt, shoulders so that said s ionlders will retard the movement of the edge of the top s tively forced forward byl the feed wheels and `kthe plate is turned or .rocked backward, as

hereinafter described. K

The flange 78, which is made integral. with the plate 77, extends obliquely vdownward and forward from 'the upper edge of the late 77 and is provided Wlth journal bearings 79, 79 on its inner faces;l By-means of the said journal bearings theguidc plate 77 is eccentrically Y mounted up,on\ 1a supporting rod- 80. The said supporting ymd80 is sup-` ported at eachend by arms 81, 81 which are adjustably' secured uponthe " gusset plates 68, 68 by means ofbolts andwing nuts 82, 82. n Midway upon-the supporting rod 80 there is adjustably secured a collar 114 whichI is provided with two arms 115 andl 116 which are adapted to limit the rocking nievement of the guide plate 7?". The arm 115is adaptedto bear against the ortion of the linner face of the late 78 -Whic 'is above the rod 80 tjolimitt t e backward movement of the rocker gun to bear against the ortion ofthe inner facev of the late 78 Whic is below the rod 80 to limit te forward movement 'of the saidv jacent to said guideboar vAs the late 77 is inclined upwardly and inwardly rom its lower to its u per margin, the sheets as they advance wi enga e the corrugations upon the face of the sai' plate andthe top sheet will rock or oscillate said guide plate, so as to bring the 'same in position to permit said top sheet to slide over the top edge of the guide late and intoengagement y `with the carrier be ts, the latter, being heavier on its ,side toward the sheet stack, will drop to position to'catch'the succeeding sheets as they are advanced toward it.

The truck carrying the stack lof sheets which are' to b e operated upon is moved to position at the receiving end of the 'feeding device and the said device is lowered until it rests with the pulleys 105, 105 upon the top surface of the sheet stack, The cam shaft 96 supporting the brackets Ul, 91 vis turned The rotation of said feed wheels moves thc i tapes 2a` and 25,
