The side arm 19 is pivoted upon a stud 21, fast to an ear 22 upon the bed-frame 10. The side arm 18 is pivoted upon a stud 23, said stud being fast to an ear 24 upon the bedframe 10 by means of a nut 25, which bears against a sleeve 26, encircling said stud 23. At each side of the form-carrier 15 is a connecting-rod 27, the lower end of which may be raised and lowered by a crank-pin or any other appropriate mechanism, thus raising and lowering the form-carrier15, said connecting-rods being pivotally attached to each side of said form-carrier by a stationary crossshaft 28.

The paper 29 is fed intermittently'by any suitable mechanism across the face of the pad 12 and below the base-plate 2O of the form-carrier and the type 13, secured to said form-carrier, as hereinbefore set forth. The ink is contained in a fountain 30, supported upon brackets 31, fast to the bed-frame of the machine. The ink-fountain roll 32 rotates in bearings in said ink-fountain and is rotated by a pawl 33, ratchet 34, and pawl-lever 35, said pawl-lever 35 being connected by a link 36 to an arm 37 upon the form-carrier 15.

Two ink-,distribution rolls 38 and 39 are journaled to rotate in bearings 40 and 41, respectively, upon the form-carrier frame. The ink-distribution roll 39 rotates by frictional contact with the ink-distribution roll 38, said ink-distribution roll 38 being rotated by a gear 42, fast to the ink-distribution-roll shaft 43 and meshing into agear 44, fast to the hub 45 upon the sprocket-gear 46. The sprocketgear 46 may be rotated by a chain connected with a sprocket-gear upon va driving-shaft. The ink-carrier rolls 47 47 rotate in bearings 48, formed in the links 49 49 of the sprocketchains 50 50. Each of the sprocket-chains 50 is driven by a sprocket-gear 51, fast to a shaft 52, which rotates in bearings 53 in the formcarrier arms 18 and 19. Each of the sprocketchains 50 passes from the sprocket-gear 51 around a sprocket-gear 54, said gears 54 being idlers and fast to a shaft 55, which rotates in a bearing 56,formed in the adjustable frame 57. Said adjustable frame is formed to slide in slots 58, formed in the arms 18 and 19 of the form-carrier 15 and is clamped thereto by clamp-screws 59, being adjusted by means of an adjusting-screw 60, the object of this adjustment being to keep the sprocket-chains 50 50 tight, so that the rolls will not sag as they are being carried from the ink-distribution roll 38 across the upper face of the inkdistribution plate 72, around the type, across the face thereof, and back to the ink-distribution roll 38. The ink-carrier rolls are each fast to a shaft 64 64 and are rotated by friction-rolls 65 65, fast to said shafts 64 and bearing upon anges 66 66, formed upon. the carrier-arms 18 and 19 and acting as an open cam-path to rotate the friction-rolls 65 and the ink-carrier rolls 47 as they are being carried from the ink-distribution roll across the upper face of the ink-distribution plate 72,

around the type, and back to said ink-distribution roll.

The shaft 52 is rotated by a gear 61, which is keyed thereto and meshes into a gear 62, which turns loosely upon the shaft 43 and meshes into the gear 63, fast to the hub 45 upon the sprocket-gear 46.

The horizontal ink-distribution plate 72, Figs. 2 and 3, is fastened by means of a setscrew 73 to a vertical shaft 74, journaled at the upper end thereof in the stationary crossshaft 28 and in the lower end in the baseplate 20 of the form-carrier. A collar 75, fast to the shaft 74, bears against the under side of the cross-shaft 28 and prevents said shaft from moving upwardly. An intermittent rotary motion is imparted to the shaft 74 by a ratchet 76 and pawl 77. The pawl 77 is arranged to slidein ways 78, formed in the baseplate 20. A spiral tension-spring 79 acts to hold the toothed end of the pawl at the left of Fig. 5 against the ratchet 76 and the righthand end of the pawl-slide against a projection 8O on the base-plate 20. Upon the upper side of the pawl-slide 77 is fastened a plate 81, which is held by the spring 79 against a cam 82, fast to the shaft 52. As the shaft 52 is rotated in the direction of the arrow c,

Figs. 3 and 5, the pawl-slide 77 will be reciprocated toward the right and left, Fig. 5, and impart an intermittent rotary motion to the ratchet 76 and also to the distribution-plate 72.

In order to guide theink-carrier rolls 47 47 With precision across the face of the type and to prevent the sprocket-chain 50 from sagging, I provide upon each side of the form-carrier a plate 67. Said plates are attached by ears 68 69 to the form -carrier 15, each of said plates being provided with a groove upon the inner face thereof, which receives a roll 7l upon the end of the ink-carrier shafts 64 64. It will thus be evident that as the inkcarrier rolls are carried by the chain 50 across the face of the type they will be held rmly in contact with said type by the rolls 71 and the plates 67, in the grooves 70 of which said rolls 7l travel as the ink-carrier rolls are passing across the face of the type.

It is evident that While I prefer to hold the ink-carrier rolls against the face of the type by extending the shaft 64 and placing a roll thereon the same purpose may be attained by projections upon the chain 50, with rolls journaled upon said projections.

The operation of the mechanismhereinbefore described is as follows: The paper 29 having been fed into position across the upper face of the pad 12, the form-carrier is brought down to the position shown in Fig. 1 by the connecting-rods 27, thus forming an impression upon the paper. When the form-carrier is raised by the rods 27 to such a position that the inkdistribution roll 39 will assume the position shown in dotted lines, Fig. 1, thus contacting With the ink-fountain roll 32, the ink-carrier rolls pass across the face of the type in the direction of the arrow d, Fig. 1, being carried by IOO IIO

the sprocket-chains 50 50. After leaving the face of the type the carrier-rolls are carried by the chains 50 upwardly around the center of the sprocket gear-shaft 52 into contact with the ink-distribution roll 3S, thence in the direction of the arrow b, Fig. l, across the upper face of the intermittently-rotated distribution-plate 72 and around the center of the sprocketgear-shaft 55,dowu\vardly and across the face of the type again to the inkdistributiou roll, being carried continuously in the samegeneral direction in a curvilinear path by the sprocket-chains 50 50.

The gearing hereinbefore described is so proportioned that the speed of the ink-distribution roll 38 is greater than the speed at which the carrier-rolls are moved, the object being to make sure of applying a su tiicient quantity7 of ink to said carrier-rolls when they come in contact with said distribution-roll and to give the same a full rotation during the time they are in contact with said roll.

It will be seen that as the shaft 52 is constantly rotated the cam SZ will impart a constant reciprocatory motion to the pawl-slide 77, thus through the ratchet 76 imparting an intermittent rotary motion to the ink-distribution plate 72, so that each time the inl;- carrier rolls pass over the upper surface of said ink-distribution plate the relative position of the surface of the plate to the inlecarrier rolls will have been changed, said inkdistribution plate rotating in a horizontal plane when in the position shown in Fig. 3.

It is evident that an endless band with bearings attached thereto for the carrierrolls might be substituted in place of the chains 50 without departing from the spirit of my invention and also that a single distributionroll could be used in place of the two rolls 3S and 39.

It will be seen that as the gears 44, 46,and G3 are all located upon the stud 23 and that stud being the pivotal centerol" the form-carrier when the formcarrier is raised and lowered, as hereinbefore set forth, the action of the gears will not be interfered with,the gears 62 and 42 revolving about the center ofthe stud 23 and also around the peripheries of the gears 63 and 44, with which they are respectively in mesh.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, is-
