' 3 Claims. (01. 101%360) p This invention relates to printing machines for linoleum, textiles and the like.

In the manufacture of linoleum, t'extilesand the like, figures or designs are in different colors or the same color to form artistic surfacesr'The printing is done by what is known as block print ing. The usual structure for' block'printing consists of a series of dies which areinked by rollers rotating in a bath in pans supportedby a travel ling linked structure which is intermittently moved back and forth to ink the die between each stroke while the material is advanced the proper distance for the next operative printing stroke of the die.

In the case of the use of different colors a number of dies must be used with the same number of inking rollers and pans forming a lengthy chain and as the motion is intermittent considerable Wear and breakage occurs causing relatively high maintenance costs. In addition, the color must be removed from the pans and. new color inserted whenever a change in color is desired. This time required for such changing materially reduces the output for each machine and inf'creases costs.

One of the objects of this invention is to provide a printing machine wherein the inking rolls and pans may be easily changed and where any one or a group of inking rolls or pans may be i removed and replaced quickly to change the color design.

Other objects of the invention will appear more fully hereinafter.

Referring to the drawings:

Figure 1 is a side elevation of a rear half of a printing machine embodying the principles of my invention.

Figure 2 is a view in elevation of the forward half of the frame of the machine.

Figure 3 is a detail view of the inking roll, pan and carrier in connection with the printing die.

Figure 4 is a cross sectional view of Figure 3, on the line 4, 4, looking in the direction of the arrows.

Figure 5 is a detail view of the carriage connection disengaged from the motivating rod.

Figure 6 is a detail view along the line 6, 6, of Figure 3, looking in the direction of the arrows.

In carrying out my invention, I provide a frame 11 carrying printing dies 2. The dies are of the usual construction for block printing. On each side of the bed of the machine racks 3 and tracks 4 are provided. The inking rollers 33 for inking dies 2 are adapted to rotate in pans 34 supported by carriages having flanged wheels 5 journaled on axles 6 carried by frames '7. A pinion gear 8 meshes with rack 3 and gears; on inking roll shaft 10. Gear 3 is adapted to be shifted in slot 13 to maintain contact between gear 9 on the end of color roll 33 and rack 3 in order to main- 0 tain proper contact when the color roll is adjusted in' height to properly kiss the blocks. A frame '7 at one end has yokes 15 through which pins 16 are journaled. Pins 16 terminate at their upper ends in eyelets 17. Pins 19 operate as stops for springs 18 surrounding pins 16, said springs bearing against one arm of yokes 15 to maintain the bottom of pins 16 protruding through the lower arm of yokes 15 and in slots 20 in rods 21. Slots 20 function not only as connecting means between frames '7 and rods 21 but also indicate the exact position for the return of the carriages after removal and upon subsequent replacement. Without such an indicating means proper synchronization of the carriage with the oscillating rod and printing die would not be possible. Frame 1 has slots 24 with rollers 22 supported by bearings 23 therein. Rods 21 are adapted to slide on rollers 22. The construction shown permits any pan to be used without using the replacing links which have been heretofore necessary. Also the carriages and inking rollers may be readily removed or replaced permitting any combination of pans being run or omitted. Rods 21 are motivated by an intermittent mechanism such as by levers 26, 27, in cams 28, 29, and spring 30 and driven through gearing 31, 32, from a source of power supply. The movement of rods 21 to the left causes gears 8 to be rotated by racks 3 thereby rotating gear 9 and inking roller 33 and at the same time moves the carriage and pan 34 and inking roller 33 to the leftto pass under the die or roll. Upon the completion of the printing by the die or roll, rods 21 move to the right again carrying the carriage '7, pan 34 and inking roller 33 under the die or roll 2 to ink same for the next stroke. In other words, the inking roller passes intermittently back and forth under the dies or roll 2 to ink same prior to each stroke. When it is desired to change the color it is only necessary to raise pins 16 by eyelets 17 and rotating the pins degrees so that pin 19 rests on shoulder 36 and then to lift off the particular inking roll, pan or carriage and replace same with another similar device. This can be done relatively quickly. In addition, as the inking devices are not interconnected a reduction of wear is accomplished which becomes more excessive in the older structures as the devices were enlarged. The same action occurring in the old structures as occurs 11;

in the case of a train of railroad cars shunting back and forth wherein the shock of the stoppage of each preceding car is passed on and increased by each succeeding car causing considerable stresses in the connections. In applicants structure each device being secured to the rods 21 do not transmit the forces to each other and hence there can be a lightening of mass in the structures and the movement thereof more easily consummated.

The dies 2 are of standard construction and the means of operation are the customary ones and no claim is made in connection therewith.

It will thus be seen that I have provided a method for inking or applying color to dies or rolls for printing textiles and the like, which will materially effect savings in the power costs,

maintenance costs, and which will more readily permit of changing of color designs without waste of materials and which can be done more cleanly.

What I claim is:

1. In a printing machine for printing linoleum, textiles and the like, an inking roll, a pan for said roll, carriages for said pan and roll, a frame, reciprocating sliding elements sliding in said frame, means for reciprocating said sliding elements, indicating slots in said sliding elements to indicate the proper position of said carriages with respect to said sliding elements, pins carried by said carriages and cooperating with said slots to connect said carriages to said sliding elements and position same, springs for maintaining said pins in said slots.

2. In a printing machine for printing linoleum, textiles and the like, a frame, a plurality of inking rolls, pans and carriages therefore, reciprocating sliding elements sliding in said frame, means for reciprocating said sliding elements, roller bearings carried by said frame upon which said sliding elements reciprocate, slots in said reciprocating elements to indicate the proper position of said carriages with respect to said sliding elements, and latching means carried by said carriages and cooperating with said slots to positively connect individually each carriage with the sliding elements.

3. In a printing machine for printing linoleum, textiles and the like, a frame, an inking roll, a pan for said roll, carriages for said pan and roll, reciprocating sliding elements in said frame, means for reciprocating said sliding elements, indicating slots in said sliding elements to indicate the proper position of said carriages, pins carried by'said carriages and cooperating with said slots to connect said carriages to said sliding elements and position same, means for positively maintaining said pins in said slots and means for positively maintaining said pins out of said slots after manual disconnection.
