METHOD AND MEANS FOR FRINTING RAISED FIGURES THE LIKE.
Application led 'January 15, 1926.
This invention relates to methods and means for printing raised letters and more in particular for printing figures and letters on dials. y
The primary object. of this invention is to provide a method and means for the rapid printing of letters, figures yand designs in raised forms to imitate results now obtained especially by the method of embossing on l" business-cards, letterheads and other kinds of printed matter.V Another important object 4is to provide means for printing figures and letters `on clock, and othera dials with semi-liquid printing compositions. such as radium compositions, for 'making luminous figures or designs on clock-dials or other dials used on measuring instruments and so forth. A further object of this invention is to provide means for printing figures with such materials by means o'f compressed air. and also to provide means which automatically interrupt the supply of compressed air to the printing composition after each printing operation. Additional features and advantages of this invention will appear from the following description considered in connection with the accompanying drawing. forming part of this application and in which 1 shows diagrammatically ka complete printing outfit built in accordance with this invention. n

ved especially for engraving the gures or symbols in small die-plates.
Heretofore7 the printing of raised figures, such as luminous gures on dials, has been performed completely by hand or by stenciling, which latter' processJ owing to the nature of the printing' composition used, and the thickness thereof needed for effective luminous radiation, requires a great amount of time for retouching purposes. The present invention performs the printing of said figures with the same kind of printing composition by means of a novel type of die shown in particular in Figs. 3, 4, 5, 9 and 10.
.Referring to these figures and assuming that the figures for a clock-dial are to be printed with a luminous compound, the printing element comprises aY die-plate 1 upon which are properly disposed the individual dies 2 for the figures. Said figuredies comprise outer wallsv Sand inner walls 4, suitably bent or engraved to reproduce the desired figures. rlhe` radium composition required for printingl is introduced between the walls ofthe figure-dies by means of small feed-tubes 5 or holes 5a. disposed substantially Vhalf-way between said walls and driven right through the die-plate if tubes are used, or drilled if holes are used. In the Vformer .case the tubes are set back a certain distance from the working edges 6 of the walls to enable a ready flow of the composition therebetween. The height orA thickness of the printed gures is determined by the. height Aof the walls of thetigure-dies, as will be understood.
The print-ing composition is introduced in a container .7, comprising the side 8 provided with the flange Swhereby the container is secured to a frame 10 by means of the screws 11. This container is closed at the bottom by the die-plate 1 whichl is secured by screws 12 or other suitable and desired means. A gasket 13 is preferably made use of to insure a tight connection between the die-plate and flange.
The container has at the top a removable cover 14 having a gasket 15, which is clamped in place by means of the hingebolts 16 and their wing nuts 17. Atn the center of this cover there is provided a stuffing-boit 18, of usual' design, through which passes the vertical` shaft 19 of the stirring device or agitator 20. yThe shaft is guided l'or rotation in a hearing' 2l. formed en a Support E22, hurinfl' a bracket 223 upon which an electric niotor .Eil nnilr be n'lonnted to o pe 'nte the agitator. rThe porter of reid inotor is tinnsinitted to the elnift lll by ineens ot Speed reducing genre repreoented by the bevel-goor;

Siinulte'neonsly the rotation oit the shaft 4.1i is (lil S lee transmitted, through the chain drive 52, to the cam 57 which opens the valve 59 while the discharge valve 64 is keptshut byV its internal spring 79.
The compressed air is therefore enabled to act on the printing composition stored in the container and said composition will be forced through the ieed tubes and deposited in the form of figures on blank dial. In the meanwhile the roller 4:2 i'ollows the contour oi the rotating cam Li?) until it drops into the recess 77' under the influence oi' the weight oi' the table 35,v assisted by the coil spring 7S acting on the lever 39. This mo# tion is transmitted by thelink 65 and the lever 67 to the T-lever 70 which is caused to rotate counter clockwise, lthus disconnecting the clutch coupling'.v Simultaneously y they supply valve 59 has been shut by its spring 80, the discharge valve 64e opened to release the air in the container and the ta'oie vlowered to remove the printed dial and insert anew blank dial. The same proc fs@ would be started again by first press down the pedal 76.y
In the present embodiment` oft my invention I have shown the use ot' three distinct motors to operate various parts of the printing plant. In practice, however. kone single motor could be made to perform all the required operations by introducing in the construction suitablemoditications which would re nire only mechanical skill to devise.
s will be understood, as suggested herein, there may be slight changes made in the construction and arrangement of the details ofmy invention without departing from the field and scope ot the same, and I intend to include all such variations` as tall within the scope of the appended claims, in this-application in which' the lpreferred forms only of my invention are disclosed.
