WILLIAM H. SGHOENBERG, OF PHILADELPHIA, PENNSYLVANIA.

OIL-CLOTH-PRINTING MACHINE.

SPECIFICATION forming part Of Letters Patent NO. 518,120, dated April 10, 1894. Application filed $eptem'ber 12 1893- Serial No. 485,332. (N0 model.)

To a/ZZ whom it may concern.-

Be it known that I, WILLIAM H. SOHOEN- BERG, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Oil-Oloth-Printing Machine, of which the following is a full, clear, and exact description.

My invention relates to improvements in machines for printing on oil-cloth or other fabrics which are fed through the machine in long webs or strips.

To this end myinvention consists in certain features of construction, and combinations of parts, as will ,be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the machine embodying my invention. Fig. 2 is a broken plan view of the machine. Fig. 3 is a cross section on the line 44 of Fig. 1. Fig. 4 is an enlarged detail View on the line 77 of Fig. 2.

The machine is provided with a long frame 10, and this carries a series' of printing mechanisms, one set being illustrated in the accompanying drawings.

On the upper portion of the machine frame and extending transversely across it is the platen 11, over which the web of material to be printed upon is fed, and this platen is re-' cessed on its upper side and opposite "ends, as shown at 11 to enable the feed belts to travel across the platen with their upper surfaces level with the top of the platen. The printing block 12 is carried above the platen and is adapted to move vertically so as to rest upon the web which passes over the platen, and this block has dovetail grooves in its top to receive the dovetail ribs 13 on the under side of the press block 14, which block is mounted in end pieces 15, the block having centrally, at its ends, trunnions 16, which are held in the end pieces, and the block is held normally in a level and rigid position by set screws 17 which project through the end pieces and into the block. The end pieces 15 are secured to vertically sliding rods 18 which are arranged on opposite sides of the machine and move in guides 19 on the machine frame,

the rods being actuated in the manner described below to impart an up and down movement to the press block and printing block. The lower ends, 20, of said rods, 18, ride on horizontal cams, 21, which are operated by worm gear 22, 23,24, and shaft 25, which is in turn operated by bevel gearing 27, 28, 29.

The material to be printed upon is arranged in a roll in the usual way, as shown at 31 in Fig. 1, and this roll is hung in the front end of the machine in any convenient manner. The material is fed forward over the platen 11 by means of feed belts 32, and an endless apron 32 carried by the belts. The feed belts are arranged horizontally on opposite sides of the machine and travel through the recesses 11 in the platen so that the apron 32 moves smoothly over the platen top. 1

The apron is provided near its side edges with spurs 32 which are adapted to engage and hold securely the cloth which is to be printed, and the belts which carry the apron run in guides 32 (see Fig. 4), which have grooves to receive the belts, and are mounted adjustably on cross pieces 32 being held on the cross pieces by set screws 32". The apron is pressed at its front end and upper side by a roller 32 which causes the material to be.

,is to be printed spurs may be screwed into these eyelets to engage the material and the material to be printed may be held between this row of spurs and one of the rows near the side edges of the apron. The apron is carried by rollers 33 which are journaled on the frame 10, as shown at Fig. 1. The rear roller has its shaft provided with a sprocket wheel 34, which is driven bya chain 35 which extends downward over a sprocket wheel 36, (see Figs. 1 and 3) on a transverse shaft 37 which is jonrnaled in the lower portion of the machine,'and this shaft is driven bya ratchet wheel 38 and pawl 39, the pawl being carried on the end of an oscillating lever 40 which is journaled on the shaft 37, as best shown in Fig. 1, and the lower end of the lever 40 connects by a pitman 41 with a crank on the wheel 42 which wheel is journaled on a suitable support 43 (see Fig. 3), and is provided with a worm wheel 44 meshing with a worm 45, on one of the driving shafts 25, and it will thus be seen that the movement of the driving shaft will cause the lever 40 to be oscillated and the pawl 39 by engaging the ratchet wheel 38 drives the chain 35 and rollers 33, so as to cause an intermittent feed to be imparted to the web carried by the apron 32, the web being carried forward during the upward movement of the press block.

The color is applied to the printing block 12 from a color box 46 in which is journaled a roller 47 and the color box is adapted to move horizontally beneath the printing block 12, so that the roller will apply the color to the printing block while the latter is in its upper position.

Each color box 47 is held loosely in a frame 47 a which has runners adapted to slide on the main frame 10 and extending downward through lugs 47 c at the corners of the box are screws 47 which rest on the bottom of the frame 47 and by adjusting these screws which are threaded in the lugs referred to, the box may be brought to any desired height, so that the roller 47 will strike with the proper effect on the printing block 12.

In the drawings two color boxes are shown, but only one works in connection with one printing block 12, the other one being adapted to work in connection with a second printing block, which is not shown in the drawings as these color boxes and printing blocks are arranged one after the other in series, the number of them corresponding with the number of colors usually printed, and a box and its block being adapted to use one color only.

Each color box 46 is provided at its opposite ends and on the under side with runners 48 which slide on the top of the frame 10 and the shaft 49 of the color box which carries the rollers 47 extends through the ends of the box may be adjusted to fit against the gear wheels 50 and the racks 52 without regard tothe height of the box 46.

The several color boxes are connected by a rod 53 which moves through guides 54 on the machine frame and connects with the boxes by means of pins 55 or equivalent fastenings. The rods 53 are arranged on both sides of the machine so that the boxes may be moved evenly and steadily and the rods have, at their front ends, racks which engage the gear wheels 56, these being journaled at the front end of the machine and near the top, and the gear wheels are provided on their inner sides with pinions 57 which engage vertical racks 58, thelatter being adapted to reciprocate vertically in guides 59 on the machine frame. The racks 58 are bent outward and downward at their lower ends, as shown at 60 and are provided with rollers 61, which travel in the grooves 62 on the cams or eccentrics 63 these being secured to a transverse shaft 64 having,

near its ends, pinions 65 which are drivenby screws 66 on the shafts 25, and consequently the cams are continually revolved while the machine is in motion, and a regular up and down movement is imparted to the racks 58, which, acting on the pinions 57, gear wheels 56 and racks 53, cause the color boxes 46 to be reciprocated horizontally on the frame top, so that the roller 47 of each color block will keep its printing block 12 supplied with ink.

It will be seen from the above description, that when the machine is set in motion no hand work is necessary to effect the printing, as the web of material is continuously fed forward, the printing block is moved regularly up and down and the color is automatically applied to the printing block.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The combination with the vertically movable press-block of an endless feed-apron arranged to move beneath the block, the apron having spurs adjacent to its edges, and arow of threaded eyelets between and parallel to said edges to receive a third row of spurs, as shown to ope rate as and for the purpose specilied.
