Referring specifically to the drawings'ixrwhich alfluidimpression. material setby the press consisting of aiconventional.press'frame lnamain press mechanismi, a'fountain kettle3, and a cleaner kettle 4. Th shaft 5 extendsfrom' the press head 6 and is journaled in theupper' plate I. Sai'dfplate 1; rectangular in shape; carriesthe slide rails'8' by means. of carriage, bolts .9, which run through the slots l0, and thesquare por tion ll of the bolts 9', preventing the turning of the bolts and'they are secured by the wing nuts I2. The slide rails 8 extend 'iromthe' front edge of'the upper plate to the rearof the press (Fig. 2). A slide member I3 is constructed of three beams l4, the ends of. which conform with the mortised edges l'5' of the rails. Each beam' has the brackets 16. screwed to it. Said brackets are slightly narrower in the width than the beams, thus affording spaciousroom for themsertion of a plurality of material membersylQ. The Fig. 11 illustratesthe spacing of the members [9, there being twelve shown butany'number may be employed. There are four banksjof members I9, the members inea'ch bank'areso constructed to allow each tooverlap the other one (see Fig. 8).

The upper plate I is slottedat 20 (see Fig.2) atifour' points to permit the. insertion of spacer rods 2l'which'extend from 'the mainpresstable 22 with pressure springs'2'3 extendingifromthe table 22 to the under surfaceofthe' upper-plate I always tendingxto keep'the plate 1." in' upward positionl A handle-2.41s secured'to the lower plate I 1 at its front edgev to" facilitate pulling the'unit'in.

and'out (see Figs. 2 and-11)..

Figure 1- illustrates the kettle '3 comprising a bracket'25xwhichis secured to 'a"'wall"26 (Fig; 9). The" kettle 3 is actually av pressure" kettle being secured by bolts ZS-around thegperiphery'and" provided" with pressure "gauge 21 "and a'safety' A series-of small containers 29 are" tained in 'the' fountain kettle -3'. A cover 3 l with a; small hole 32' covers each individual retainer. Extending from each'retainerf is a pipe 33 provided with 'a cock 34, each .pipe continuing-to one of the material units. Said' units. comprise a nipple 33' to which the'pipe 33 isjournale'd, a

bore' 3.5 which houses a valve'member; 36 which ends in a pusher rod .31. The units 19' "are screwed into the moldzplate38 which is :secured to the lower plate: ['1 by the screws 39. The molds Ml may be. of anyrequired designgillus trated are Squares, triangle and hexagonal forms and are centered around the unit l9. Spaced between these molds are pusher pins 4| driven outwardly by the springs 42 bound in the bores in the plate I! and abutted by the plugs 43.

In operation, a lever 44 extending from the side wall of the press is pushed downwardly from position A to position B. During this pressure the mechanism (not shown) inside the press housing is actuated, driving the press mechanism 2 downwardly to a position shown in Figs. 5 and 20, at which point it will be seen that the pusher rod 31 of the fluid valve 36 has been retracted allowing escape of the fluid material into the mold and onto the paper. The fluid material is forced out of the fountain 3 under pressure which has been stored up in the kettle 3. Approximately twenty-five pounds of pressure is employed. At this operation almost all of the air pressure is expended thus requiring more pressure for the further operation. To provide for this the air valve 45 is secured to the side wall of the press convenient to the lever 44. As the said lever 44 is moved from position B to position C, the handle bears on the roller 46 forcing the arm 41 downwardly on the pin 48 opening the valves, thus permitting air to flow through the valves through a pressure cylinder, not shown, into the press mechanism which drives the unit 2 upwardly again. The remainder of the air goes through the pipe 49, up through the check valve 50 and into the pressure kettle 3, thus replenishing the necessary pressure.

Upon using of the unit 2 (Fig. 21). the pins 4| will bear against the paper P holding it down and preventing it from adhering to the surface of the molds. This results in a series of sharp impressions 51 being of the same shape as the molds.

The paper is stacked onto the table 22 of the press and centered against the fences 52, said fences 52 being set by the adjusting screws 53. (See Fig. 7.)

Figures 13 to illustrate the check valve 50, the valve 54 being driven from its seat 55 by the air, against the spring 56 and the spaces 51 permitting air to travel through.

A provision is made for cleaning the pipes when the change of color fluid is required. A cleaner kettle 4 of similar design as the fluid kettle 3 is provided. Said kettle 4 is secured to the wall 26 by the similar bracket 25 but is cleaned by pressurizing. However, the twelve pipes 58 also run from the kettle 4 and are connected to the pipes 33 below the cocks 34, and are also provided with the cocks 59. When cleaning is necessary the cocks 34 are closed and the cooks 59 are opened thus permitting a flow of cleaner fluid through the pipes and into the material pipes Ill. The mechanism 2 has been previously pulled out on the slide rails 8 (Fig. 11), thus facilitating cleaning the molds at the same time. A counter 60 (see Fig. 2) is secured to the side wall of the press from which a rod 6| extends to the shaft 5. Every time the shaft is lowered the counter registers another impression through the action of the rod 6| against the counter lever 62.

Although the drawings and specification disclose the best 'means in which I have contemplated embodying my invention, I desire in no way to be limited to the details of such disclosure, for in the further use of my invention, slight changes in form and proportions may be made without departing from the spirit of the inven- -to said frame, press mechanism adapted to reciprocate said plate toward and away from contact with a sheet on said material support, said plate being provided with an aperture in communication with each of said depressions, a valve carried by each of said apertures, each of said valves having an inlet end connected to one of said conduits and an outlet end in communication with one of said depressions, a valve actuating member provided at the outlet end of each of said valves adapted to be actuated by contact with said sheet material upon the downward movement of said plate to thereby discharge said liquid material upon said sheet material within the confines of the walls of each of said depressions.

2. A device for applying predetermined quantities of coating liquids to the face of a sheet of material comprising, a press frame, a fountain kettle mounted on said frame, a plurality of liquid containers mounted within said kettle, each of said containers being provided with a liquid conduit leading therefrom, a mold plate provided with a plurality of depressions on one face thereof, material supporting means secured to said frame, press mechanism adapted to reciprocate said plate toward and away from contact with a sheet on said material support, said plate being provided with an aperture in communication with each of said depressions, a valve carried by each of said apertures, each of said valves having an inlet end connected to one of said conduits and an outlet end in communication with one of said depressions, a valve actuating member provided at the outlet end of each of said valves adapted to be actuated by contact with said sheet material upon the downward movement of said plate to thereby discharge said liquid material upon said sheet material within the confines of the walls of each of said depressions, an auxiliary kettle adapted to contain a cleaning fluid secured to said press frame, a plurality of conduits for said cleaning fluid carried by said kettle, the free ends of said conduits being adapted to be connected to the inlet ends of said valves whereby said cleaning fluid may be conducted through said device by the operation of said press to thereby subject the entire liquid conducting system to the cleaning action of said cleaning fluid.
