INK PAD Original Filed Jan. 18. 1933 Patented Jan. 15, 1935 UNITED STATES INK PAD Commodore D. Ryan, Los Angeles, Calif., assignor to National Postal Meter Company, Los Angeles, Calif., a corporation of California Original application January 18, 1933, Serial No. 652,255. Divided and this application April 2, 1934, Serial N0. 718,662

6 Claims.

This is a division of my co-pending application, Serial No. 652,255, filed January 18, 1933, and the invention set forth herein relates to an ink pad of a type particularly adapted for use in printing presses, such as set forth in the above application.

One of the objects of the invention is to provide a removable inking pad for printing presses, which will operate satisfactorily over long periods of time without attention.

It is a further object to arrange the inking pad whereby the stamp engaging surface thereof may be readily renewed at small expense when worn out, and to provide means for pressing the pad against the printing type or die in a manner to cause as little wear of the pad as possible.

Further objects and advantages will be apparent from the following description, taken in connection with the accompanying drawing, in which,

Figure 1 illustrates a perspective view of the ink pad of my invention;

Figure 2 illustrates a perspective view taken from the bottom of the device when partially disassembled;

Figures 3 and 4 illustrate perspective views of the disassembled parts of the pad, shown in Fig. 1;

Figure 5 illustrates an enlarged, sectional View taken on line 5-5 of Fig. 1.

In the preferred embodiment of the invention, as illustrated in the drawing, the inking pad assembly includes a slide 11 and a replaceable ink pad 12. The slide 11 includes a pan 13 which has side walls 14 and 15 and end walls 16 and 17. Formed in the end walls 16 and 17 are holes 18. The wall 16 has a notch 19 and a threaded hole 20, a notch (not shown) being provided in the opposite end wall 17. Positioned in the pan 13 is a felt pad 21. Resting on pad 21 is a pair of springs 22. Permanently assembled with the pan 13 is a plate 23 which has fingers 24 at its ends, these fingers being received by the holes 18 in the end walls 16 and 1'7 of pan 13. The springs 22 urge plate 23 away from the pan, so that fingers 24 are normally disposed at the top of holes 18. Formed longitudinally in plate 23 are downwardly extend-- ing ridges 25 and 26. As shown in Fig. 5, the ridge 26 is deeper than ridge 25. Downstruck from the plate 23 is a pair of ears 2'7 for the purpose of positioning one of the springs 22. It will be noted in Figs. 1, 2 and 5 that when pan 13 and plate 23 are assembled, the notch 19 in the end wall 16 lines up with a channel 28 formed by the ridge 25 of the plate 23.

The replaceable ink pad 12 includes a pan 29,

(Cl. 101-335) I comprising a floor plate 30 having side walls 31, the outer portions of which are bent downwardly to provide flanges 32, as shown in Figs. 3 and 5. The ends 33 of the pan 29 are provided with thread holes 34. Provided in the pan 29 is a felt pad 35, over which a cover cloth 36 is fixed, the ends of the latter being secured to the pan 29 by threads which pass through the thread holes 34. The cloth 36 is held in place on the pan 29 by an assembly plate 37, the latter having outstruck lugs and a ridge 39 provided thereon, as shown in Figs. 3 and 5. The replaceable ink pad 12 is assembled by folding the side portions of the cloth 36 tightly over the flanges 32 of the pan -29, moving the assembly plate 37 upwardly into position between flanges 32, as shown in Fig. 5, and then bending the flanges of the pan inwardly to firmly clamp the cloth between these flanges and the assembly plate 3'7.

The replaceable ink pad 12 is placed upon or removed from base slide 11 by sliding the outstruclc lugs 38 over the edges of plate 23, as shown in Figs. 2 and 5. It is desirable that the ink pad 12 go on the base slide in. one position only, this being assured by the provision of the ridges 39 on the assembly plate 37 which prevents the pad 12 from being placed on the base slide 11 in any other way than with the ridges 39 passing through the notch 19 into channel 28 provided by the ridges 26 of plate 23. The inking assembly 10 may then be placed in the printing machine in the manner described in my co-pending application.

Although I have shown and described but one form of my invention, it is to be understood that various changes and modifications may be made therein without departing from the spirit of the invention or scope of the following claims.

I claim: I

1. In combination, a yieldable base, an ink pad, means for detachably securing said pad on said base, and key means for preventing the assembly of said pad on said base in other than a single desirable relationship.

2. In combination, a base unit, an ink pad deck plate mounted thereon with a degree of play in depth, an ink pad carried by the deck plate, primary resilient means extending said plate a maximum distance from said unit, secondary resilient means, and stops limiting the distance said plate may be depressed before bringing said secondary resilient means into action,

3. In combination, a base unit, an ink pad deck plate mounted thereon with a degree of play in depth, an ink pad carried by the deck plate, primary resilient means extending said plate a maximum distance from said unit, secondary resilient means, and stops limiting the distance said plate may be depressed before bringing said secondary resilient means into action, said stops being formed on said plate.

4. In combination, a: base unit; an inkpad deck plate mounted thereonwith a degree of play in depth, an ink pad carried by the deck plate, primary resilient means extending said plate a max imum distance from said unit, secondary resilient means, and stops limiting the distance said plate may be depressed before bringing saidisecondary 5. In an article of manufacture thacombi nation of a base unit having a deck plate yieldably mounted thereon, an ink pad, a pad face member having a back plate, tongue and groove means provided on said plates to facilitate their being slid together to secure said member on said base unit, and key means on said unit and said member preventing assembly of the latter except in a given relation.

6. In an ink pad structure a base-member, a floating plate mounted upon said member for predetermined movement relative thereto, means for resiliently urging the floating plate to the outer limit of its movement, a flanged ink pad pan, an ink pad mounted in the pan, a cloth covering'for thelpadextending around the flanges of saidpan, an assembly plate against which the fianges'of said pan are bent to secure the cloth padcovering to the pan, and means for removably mounting: the .assembly plate onto the floating plate.
