"upper inutili' ridge olf tlm section L willi mm@ The exti'imioiis A end of one of its trumiicns, so that the said cylinder B may be. operated by hand. Gn

the same trunnicn to which the handle or y of a pinion 34, which is scour-edito this truncrank-arm B is secured a gear 23 is 'fastened at the outsidc'of the cheek-piece at that side of the machine, and the said gear 23 meshes with a similar gear ,24, correspondingly se- 4 cured to the trunnion 22 for the bed-cylinder @,as is shown best in Fig.; 1, so that by the operation of the printing-cylinder B the bedvcylinder C is correspondingly rotated. y Two eedrollere-an upper one 25 and a lower one`26-are mounted to turn at the forward or delivery end of the machine, the roller 25 being provided with trunnions 25'* and the roller 26 with trunnions 26a. The feed-roller 25 is located opposite the front lower portion of the -cylinder B, being practically mounted at the upper section a of the extension A from the cheek-pieces, while the lower roller 26 is journaled in the inner or deeper section a of the sald extension', as is clearly illustrated in Fig. 2 and indicated in Fig. 1. In front of the two foriiard feed-rollers and 26, opposite the point where the two rollers substantially engage, a table 27 is formed, which extends from the lower edge of one member a of the cheek extension A to the o posip member or section a, as is shown aso in igs. 1 and 2. A third feed-roller 28 is employed, and this third feed-roller 28 is journaled in the cheek-pieces A in auch manner that it willengage with the bed-roller C at the upper rear portion thereof, as is illustrated in Fig. 2. The rear feed-roller 28 is journaled in what may be termed swinging and adjustably-Inounted bearings 29. Under this form of bearing, into the hubs of which the trunnions 281`ofthe rear feedroller 28 are mounted to turn, the said feedroller may be adjusted to or from the bedcylinder C or may be adjusted upward or ldownward tangentially to the said bed-cylinder. The upper forward feed-roller 25 is prov vided with a swinging adjustable bearing 29a,

so thatit may be adjusted to or from its mating or lower feed-roller 26 but the trunnions 26a of the lower forward feed-roller 26 are simply journaled in the frame, and this roller 26 does not need to be adjustable. l

At a suitable point between the u per and lower ends of the main .sections of the cheek pieces of the frame recesses 31 are formed in the rear edges of the said main sections A, adapted to receive the trunnions 3Oft of a spool 30, as is shown in'Figs. l and 2,' the said spool being removabled'rom' the said recesses. On the spool the aper 32 to be printed upon is wound, and t is paper: is led forward between the rear feed-roller 2,8 and the bed-roller C, then between the bed-roller C and the printing-roller B, and the paper after receiving its impression is passed through the forward feed-rollers 25 and 26 and overthe table 27 to be acted upon by a v feed-roller 25 at the geared side eresie cutting mechanism located at' the forward end of the machine.

The rear feed-roller 28 is driven by means nion at that eide of the machine where the gearing 23 and 2e is loceted, and the pinion 34A fneshes with the teeth of the gear 24. The forward feed-rollers 2,5 and 26 are driven in the following manner: A. pinion 36 is mounted on the trunnion 25a of the upper forward o; 'the frame, and this pinion 'meshes with a pinion 38, located on the trunnions 26S of the lower for- Ward feed-roller 25, also at the geared side of the frame, The pinion 38 meshes with the teeth of the pinion 36, while the teeth of the pinion 38 meshes with the teeth of a pinion 39, located below it and mounted to turn on a stud d0, carried by 'the frame. The said pinion 39 meshes with the teeth o1c the gear 24, carried by the bed-roile'r C. l

The cutting mechanism consists of a frame D and a knife E, which is carried by the frame. The frame is located at the forward upper portion of the machine at the terininai ends of the sections c of the extension A from the mani portieri A of the cheek-pieces, as is best shown in Figs. i, 2, and 4.' This frame ,extends from side to side of the machine and consists ci an upper iront plate 41, side members 42, with which the plate is ingrally made or to which the plate is attached, and a lower cross-bar 43, extending from one side 42 to the other, having members 43E", which extend rearwardly to a sliding engagement with the lower edge of the forward upper sections a of the iraineVas is also shown in Figs. 1, 2, and fi, together with rearwardlyextending arme 4d, carried from the sides 42 of the frame, which arms d4- are mounted to slide in slidewaye `or slots 45, produced inv the said frame .enibe'rs' or sections a', as is best shown in Li, and each ci the arms 44 is provided with an outwardly-extending foot 46 at its inner end. Springs 47, as is best shown in Fig. 2, are attached to the inner faces of the said forward upper members a or the frame and to the front plate 41 of the knife -carxying trarne D, and a suiiicient s ace is provided between the lower edge of the said front plate or the knife-carrying frame and the lower bar 43, as is clearly shown in Fig. 2, to permit the free outward passage of the printed. end of the paper while the knife E, to be hereinafter described, is in its upper position, and when the knife is lowered it severe the printed portiono the paer into predetermined-lengths. The knife is located at the' forward portion of its carryin #frame D, and the cutting edge e of the IOG IIO

said r'pife may be plain, but is preferably serrated or in scalloped iorn, as is 'illustrated in Figs. 3 and 5.
