cc; is l: ro ements in Block-Printing Machines, vhich the following is a speciiication.

{hie ohject of m invention is to construct a. block printing machine for printing material, such as oil cloth, linoleum, and other which are fed intermittently through a machine and in which there is a series of =cating block carriers which it'ug blocks that make the im pressions as the material is fed through the machine.

A further ride mean clock on make a object of the invention is to protor automatically controlling the o that any desired block can ion at time.

er object ol the invention is to con 3t a come for printing bordered rug... or mats and similar iioor or table cow erings.

. 1 mg ma nine, but other forms he used Wi hout depa Irom the es- H13 V I sential e ire oi .ne invention, which is to ically control the clocks so as to allow them to print any predetermined time. Furthermore, Where the intention used to i ting rugs having an endless n (3, is a .ransverse sectional View on the border and Where it is desired to make more than one size of rug, the controlling mechanism is so timed that any of a series of blocks can be allowed to make the impres-. sion. In the present instance, each block or set of blocks prints the full Width of the machine and eighteen inches in length, and the feeding mechanism for the material to be printed is so arranged that, said material will move intermittently for eighteen inches, re maining stationary for a sutiicient length of time to allow the block to make the necessary impression. Thus I am enabled in one machine to print the bodv of a rug, Where plain centers are duplicated from one to a series of times according to the length of the rug, and to properly print a border section eighteen inches wide, in the present instance at each end of the contemplated rug. The printing blocks are controlled by the automatic mechanism which I will now proceed to describe.

Referring to the drawings, 1 is the frame of the machine consisting of an upper beam 2 and a lower beam 3. This frame ,is built in the ordinary manner and on the up or beam 2 are vertical guides 4 for the block carriers 5. These ranged to reciprocate vertically in the guides and consist of vertical slides (5 at each side of the machine and connecting beams 7 extending from one side of the slide to the other, making the rigid construction which is essential in this type of machine.

8, S are the printing blocks, which are detachably secured to the carriers 5 in the or dinary manner. These blocks may be arranged in sets or in one piece as desired, and can be adjusted so that they will print true on the material which is fed intermittently through the machine by endless bands 28 having pins which engage the material.

block carriers are ar-'- 9, 9 are the inking elements having Wheels I 10 which travel on rails 11 secured to the frame 1, and these inking elements are connected together by rods 12 and means are provided for reciprocating the rods longitudinally so that the rollers of the several inking mechanisms will pass under the blocks 8 and will ink the projecting surfaces of the blocks. The rollers rotate in the ink fountains, which are made as shown in Figs. 8 and 6.

i3 is a cam shaft, one for each block, and these cam shafts are drivenin unison and thereon.

at the same speed in the present instance. At each end of each cam shaft is a cam ll havmg an extension 15, and on the carrier 5 are studs 16 in which are mounted rollers 17' which are engaged by the cam, so that, as the cam rotates, it raises its carrier and the extension 15 insures the return of the carrier to the printing position. There'is a long dwell in the cam so as to hold the carrier in the raised position in order to allow the inking mechanism to pass under the printing blocks and to distribute the ink Projecting from the side of the carrier, in the present instance, is a lug 18 with which engages a latch 19 pivoted at 20'to the frame.

21 is a pivoted keeper which, when turned by hand, will retain the latch in engage ment with the lug 18, holding that particular block carrier out of action. This is used when it is desired to dispense with the'use of any particular block.

()n the latch 19 is an arm 22 having a weight which causes the latch to automatically disengage the block carrier. The cam ll has a high portion which lifts the carrier above the position of rest so as to al low the latch to move out of engagement with the lug 18. The latch and the lug are beveled so that when the full weight of the carrier is on the latch it will be held in position and can only be released when the carrier is raised.

At each side of the machine,in the present instance, is a series of latch actuating rods or selectors 24; three rods are shown at each side and on each of these rodsare collars 25. In the underside of the collars are screw threaded holes adapted to receive detachable pins 26 which are held in position by set screwsd ig. 10, or other fastenings, and on each latch is a pin 27 which projects under the rods at the collars, so that, if there is a pin on any one collar and that particular rod moves forward, the pin 26 will engage the pin 2? of the latch, forcing it into the path of the lug 18 on the carrier 5, and as the carrier leaves the high part of the cam it will be held by the latch until released again by the return movement of the rod 524. The several rods 24 have their hearings in b ilCh'GtS on the frame 1.

36 is a cam shaft at one end of the machine, Figs. 4: and 7, and at each end of this shaft are three cams 37 and on the end of each rodZl is a head 38 shaped to receive the cam and each head has a roller 39 which bears against the face of the cam, so that each rod is reciprocated according to the 60- particular cut of the cam. The cams only move the rods in one direction in the present instance. A. spring 30 on the opposite end of each rod bears against one of the brackets 35 and movesthe rod in the opposite direction. An an:-

quired. The same is true when there is only diary spring 31, for the same purpose, may be used if found necessary, Figs. 2 and 8. The cam shaft '36 controlling the rod is driven from one of the main cam shafts 13, through a shaft by belting, as shown by dotted lines, Figs. 2, 3 and l. By using the detachable cams 37 and detachable pins :26 the several carriers are under control of the cams and their rods and can be moved into the printing position at any predetermined time.

Referring to Fig. 12, which illustrates in diagram a rug seventy-two inches long, it will take four impressions to print this rug :1 single color. A single block will make two impressions a; which will have the body and a portion of the border 3 at each end, while the impressions w, w will be the end portions of therug and will have the end. borders .2 and side sections ,7 of the border, and each end will require a separate block. If there are three colors used in printing this rug, then the several portions m of the rug will be printed with a set of three blocks. one following the other in the order determined upon by the operator. Then the end 00 of the rug will be printed with three blocks and the opposite end u." will also be printed with three blocks, so that it will take nine blocks to print a rug of this type haw ing three colors. If, however, the rugis ninety inches long then there will be three impressions a: and the same border impressions will be made; Consequently, the same number of blocks, vim, nine, will be reone sect-ion a', so that a threecolored rug of any length desired can be printed with nine blocks. These blocks, by my improved mechanism, can be automatically released so as to print at the proper time as the desired portion of the material comes under the printing block. Thus it will be seen that I provide automatic means for controlling the movement of the printing blocks. so that any block of a series can be controlled to make an impression at the proper time.

I have shown the invention as mechanically operated through rods and cams, but it will be understood that the latches can be actuated by pneumatic or hydraulic mechanism, using a series of cylinders in which are plungers, either directly on the latches or indirectly through the above described rods.
