'The is mounted in suiters a, one coacting frame at its extremity meshes with the Carried alsoby that Aend of the shaft e, but inside the frame, is another pina pinion e3, mounted e on the shaft of the feed-roll E. The lastnamed shaft is mounted inthe frame inema separator-rch, plleferably-` Y "of rubber or having a rubber periphery, lonor corrugated. Y The shaft f of said separator-roll is mounted in the side as shown at d, one end of said inion d. Adjacent to and adjustable relatively thereto is an idler-roll D', the ends bearing-blocks dz, withcranks on the operated by fingeridler'- roll toward or ICO bers e in the same manner as is theshaft of ,one of the pressing and passing rolls presently to be described, and since the mounting of the latter. is more clearly 'shown in vthe drawings further description of the mounting of the shaft of said feed-roll E is here omitted. The pinion 2 meshes with an idler-pinion e", carried on the inner face lof one of the frame members and meshing with a pinion e5, mounted upon the shaft e of one of the pressing and passing rolls F, whieh roll is preferab y metallic. Said shaft e `is here shown as the main shaft of the machine, Ithe ends thereof being journaled in the frame members a and passing through the same, one end of said shaft being provided withthe drivewheelf and the other with a pinion f the function whereof will be presently explained. The pinion c meshes with a pinion g, mount- -ed upon the shaft g ofthe pressing and passinfgroll G, which coacts with the pressing and passing roll F. Said shaft g is mounted at its ends in the frame members ain manner simi.- lar to the mounting of the feed-roll E, this including at each end the use `of a bearingblock g2, in which. the shaft lend is journaled and which has sliding movement in an openmg in the frame member and a yielding pressuredevice coactingwith said block and comprising the'barrel g? andthe spring-pressed plunger g, operating therein and tending to force said bearing-block and the shaft end journaled therein toward the roll F. This provision with regard to spring-pressed coaction of the pressing and passing rolls F G is also true with respect tothe feed-rolls E E.

H designates a deli\'eryroll, havinggpreferably, a rubber-covered periphery and mounted upon shaft h., the ends whereof are iournaled in the frame members a by means of the sliding spring-pressed block construction-just described in connection with the pressing and passing roll G. Mounted upon the shaft of said roll H is a pinion 71.','wliich meshes with the pinion c5 on the main shaft (if U/ e designate ears, preferably formed integral with the frame members a, and upon thesev is detachably mounted (see set-screwsl i) a cross-bar if, carrying the sheet guide or buclder l.. Said cross-bar is provided with an" inwardly-projecting web "Z2, to which are secured the parallel guide members i3 i". ll`he free end of the latter terminates in proximity tothe periphery of the delivery-roll H, while the correspondiiigend of the guide member i vis curved and terminates in proximityto the peint of eoaction between vthe peripheries of ythe passing and pressing rolls l? G.

i5 designates a sliding stop operating between and extending from edge to edge of the guide members i. i4. and a'portion of the guideinember i is a i vplate i", secured/to the cross-bar i and hav-- ing an elongated slot t', through which oper- (.lverlying said stop" ates a screw-stud i 'carried b s'aid sto i5 a set-nut i. As will be readily understood,

'moved to any suitable point4 between'the guide members4 i i* and firmly clamped in proper position, the object of said stop being the guide members i i* of a folded sheet fed therein from between the passing and pressing rolls F G. v

'L desi nates a rock-shaft jouinaled at its ends in t e side members a of the frame, one end projecting throu h such frame and being provided with a cran -arm Z, the end whereof is attached to the connecting-rod Z', running to the crank-arm Z2 of eyeloineter Z3. The

shown in Fig. 2 by means of coil-spring Z4. Mount-ed up'on the rock-shaft L and projecting inwardly therefrom are arms m, to the inner ends whereof is secured the angular guide-plate M. Said guide-plate, as clearly shown in Fig.- 5, is rovided with the web m',

.tion of the periphery of the roll F and the portion m2 at right angles. thereto and constiedge of a sheet fed between the rolls F and H. Additionally, said guide-plateM is provided with downwardly and inwardly projecting lips m, terminatin in close proximity to the peripheryof the ro l tional guide-rolls n, each about coextensive 1in length with the distance between two adjasite-such space. Theends of such guide-roll shaft are mounted in'han ers n', depending fr o'rnvthe main shaft e". Adjaeent' 4to one of the ends so mounted said shaft N is provided with a pinion n2, which meshes with the pinion h of thedelivery-roll H. As clearly shown in Fig. 3, the guide-roll shaft N and sectional rolls 'n thereon operate in close proximity to the peripheryof the deliyerysure in this position by means of'springs as 1L, said springs also serving-to maintain the pinion'n2 in eoaetion with the inion h Lying directly below' the point of coaction of-the sectional guide-roll n and delivery-roll His the stripper-plate P, secured in any suitable rnanner to the side members ..of the frame. The upper edge of said 'Slate termi- 'iiateseither in Contact with or in close proximity tothe periphery' of the delivery-roll H, lso as to receive upon its outer surface a folded sheet fed between said`delivery-roll and said sectional roll. Said plate is provided with an elongatedvertioal slot p, through which works the screw-stud p on the end of the adand with the threaded portion whereof coacts to determine the degree of traverse Within substantially para lel with the coaeting por-v tuting a guide-stop for the advancing (folded) cent lips m3 on the guide-plate Mand'oppojusting thumb-piecep, said screw-stud co, acting with a threaded perforation in the de- 'l the stop "i5 may, by reason of said nut i", be l Y crank-arm Z is normally held in the position lN' designates a guide-roll shaft having s ec- IOO roll H and are maintained by yielding pressettle vwith a longitudinally' flute or corrugated periphery, preferably of rubber. The periph- -ery of said forwarding-roll extends slightly labove the surface of said ways, so as to forward upon the same the folded sheets Vfed thereon. The extreme end of the bearinglug 1'5 is vyoke-shaped, comprising the members r r, and loosely journaled in said members so as to have vertical freedom of movenient is a shaft S, which shaft is provided between the members rl 7 with the spiral. gear 8, meshing with a corresponding gear s on the extreme end of the forwarding-roll shaft r. The upper end of said shaft is journale in the ends of the yoke s2, secured to the exterior of one of the frame members a, and has keyed or otherwise secured thereto within said yoke the spiral gear e3, which meshes with a similar gear s* upon a stub-shaft S5, secured to the said frame member. 'lhe spiral gear s4 is driven by a pinion s", mounted upon said stub-shaft and driven by the pinion f on the main shaft e6. 1t will therefore be seen that the support R for the inner end of the delivery apparatus may be raised or lowered (by means of adjusting thumb-piece fr, te.) without interfering with the means for driving the forwarding-roll R2, the .yoke members 1 r and spiral gear Lslicing, as above stated, free to move upon the shaft T 'il designate are-shaped slots formed opposite each other in the frame members (L a.,y and within these slots operates a cross-rod t, one end whereof is provided with a head t', the other end being threaded and provided with a set-nut similar to the nut p2, whereby after said cross-rod t has been moved to any desired position within the slots ,'.l it may be there securely clamped. Carried by said cross-rod and between the said members of the. frame is the si1pportingvbracket t2, having ears t, to which the ways l lt are secured, as shown in Fig. l. Oiorating upon saidways is the sliding block U, movable ,hereover toward and from the s tripperplate l). 1t will therefore be seen that any desired inclination of the ways lt lt may be secured by means of either one or both ,of the two independent adjustments herein described. .ln the specilic form of the mechanism disclosed the guide-roll n should coact with the upper edge of 4the folded., sheets in order to and there y o en a space rearward of the stripper-plate lEfor the reception of the next succeeding folded sheet. Inasmuch as sheets of different sizes are to be folded, it is desirable that the inner end, whether with or independent of the outer end of the deliveryways, should be adjustable toward and from said guide-roll n. This is accomplished by the mechanism described, it being possible to readily elevate or depress the inner end of the guideways and to secure the same in adjusted position by means of the set-nut p2. The outer end of said ways may, if desired, be corres iondingly changed by means of the slots cross-rod t, and supporting-bracket carried by said cross-rod.

The operation of the machine has been to some extent explained in connection with the foregoing descriptiony of the parts. The lowermost sheet is fed from the pile by means of the separator-roll l), buckled, as illustrated in Fig. 3, and passed downwardly to the feedrolls E E, which thereupon grasp the buekled portion and feed the sheet downward to the pressing and passing rolls F G, after passing through which the advancing (buckled) edge passes into the sheet-guide l until its movement therein is arrested by the stop t, whereupon the sheet is again buckled and fed to the grip of the rolls l" Il. The advancing (folded) edge strikes against the lips m and operates the rock-shaft li, which thereuponlreeords the passing of such sheet upon the eyclometer Z. Such edge is thus guided downwardly between said roll lI and the scctional roll It and passed to the ways it', the upper edge being moved outwardly (away from the stripper-plate P) by means ol said sectional roll. This operation being co'ntinued, the sheets of the entire pile ariv` successively folded and stacked upon said ways,

. the sliding block U being moved outwardly therefrom by the accnnuilation of such folded sheets and the action ol' the forwardingroll lii.

l claim as new therein, and desire to secure by Letters Patent, is as follows:
