INK PAD AND METHOD or MAKING THE SAME.

Application filed July 7, 1921. Serial No. 482,827'5.

To all whom it may concern.'

Beit known that I, ROBERT H. Kms, a citi zen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Ink Pads'and Methods of Making the Same, of which the following is a specification. y

My .`nvention relates to an improved inking pad and the method of producing the same; the principal objects of my invention being to generally improve upon and sim" plify the construction of the existing types of inking pads, further to provide an inking pad having two inking surfaces, thereby permitting the pad to be reversed and consequently materially increasing the life or term of service of the pad, further to provide a relatively simple and practical pad thatis particularly adapted for use in the resilient stamp pad holder disclosed in the application for patent filed by 'Whitney K. Munson and myself, April 11, 1921, Serial No. 46O,-l

592, and further to provide a relatively simple and easily practiced method of producing inking pads whereby the cost of manufacture thereof is minimized, and an inking pad having a maximum degree of inking surface is produced.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more fullydescribed and claimed and illustrated inthe accompanying drawings, in which:

Figure 1 is a plan view of an inking pad produced by my improved method.

Fig. 2 is a perspective view of one of the rings or angular members that forms the frame of my improvedpad.

F ig. 3 is a perspective view of the companion ring or frame forming member of the pad.

Fig. 4 is an enlarged detail section taken through the edge portion of a pad and showing the parts thereof in the positions occupied prior to the iinal finishing operation'.

Fig. 5 is an enlarged detail section taken approximately on the line 5-5 of Fig. 1.

In the construction of my improved inking pad, and by my improved method of manufacture, a ring or annular frame member 10 is pressed or stamped from sheet metal, and the body of said ring or frame memberl being substantially L-shape in cross section and with the horizontally disposed flange 11 inwardly` presented.

In the manufacture of this ring or frame member the cutting and stamping operations are performed so as to produce a minute burr l12 on the inner upper edge of the inwardly presented flange 11, and which burr is effective ingripping the fabric covering or facing of the pad and preventing the same from pulling awayfrom the marginal frame of the completed-pad.

f A companion ring -13 is pressed or stamped from suitable sheet metal, and the. body of said companion ring being of inverted L- shape in cross section and with its horizon-r tally disposed flange 14 inwardly presented. In'the construction of this companion ring or annular frame member the dies forming the same are manipulated so as to produce a relatively small burr 15 on the lower inner edge of the flange 14, such burr being effective .in gripping the corresponding fabric coveringof thepad and vprev'entingtheA same from pulling away from themarginal frame.'

The external diameter of the .vertical flange of ring 13 is s'u'ch that said ring fits snugly withinvthe upstanding flange of the ring or frame member 10i, and the width of the upstandingliange of ring 13 is substantially less than the vwidth of the upstanding flange of ring 10, so that whenthel two lrings of frame members are properly assembled the upper portion of the verticalv flange af ring 10 will'project above the top or inwardly presented Aflange of ring 13. When the two rings or parts of the marginal frame of the pad are properly assembled by being. pressed together, the thickness of the finished frame is substantially less than the thickness of the body of the pad (see Fig. '5). f

- An absorbent portion of thexpad comy prises a body 16 of suitable` fibrous material, the same being interposed between facing members .17 `of' .suitable absorbent flexible material, preferably woven fabric, and thisk absorbent body is lof circular .form andof such-sizefasto fit snugly withinth'eframe comprising the rings 10 and 13. In lthe pro-v duction of the pad by my improved method, the edge of the absorbent member compris-- ing the absorbent body 16 and facing member 17, is positioned between the horizontally disposed flanges 11 and 14 of the rings or frame members 10 and 13, as illustrated lUO 1 ioA i after which the inverted L-shaped ring 13 is forced downwardly within rino; or frame member l() until the lower end of the vertical flange of said member 13 engages the flange il of member 10. inward and downward pressure is now applied to the projecting upper edge of upstanding flange of member l() so as to bend said proecting edge inwardly and downwardly onto vthe outer portion of the'inwardly projecting flange A- of member 13, and at the same time pressure is applied to the outer faces of the flanges 1l and lll so as to bend the same inwardly toward each other and into angular positions with respect to the vertical flanges of the rings or frame members, thereby compressiiw the edge of the absorbent body of the "pad and causing the burrs l2 and l5 on said inwardly projecting flanges to engage in the fabric facings of said absorbent body, with the result that said facings will be effectually prevented from being pulled away from the annular frame of the pad.

Thus it will be seen that l have produced a construction utilizing relatively few parts, thereby enabling the pad to be easily and cheaply manufactured, said pad being comparatively light in weight, of substantial structure, provided with a pair of inking surfaces, and the method of producing said pad involving a minimum number of operations that may be easily and quickly accomplished.

lWhile l have shown and described a in Fig. l

round or circular stamp pad, it will bev understood that practically the same method may be employed in producing pads that are substantially oval or rectangular in shape, and that the improved pads may be used in any suitable base or receptacle, although, as above stated, they are particularly designed for use in connection with the base disclosed in the hereinbefore mentioned co-pending application, Serial No. 460,592.

l claim as my invention:

l. In an inlring pad, a frame composed of a pair of members that are substantially L-shape in cross section, one member being arranged within the other and with the horizontally disposed flanges of said members inwardly presented, and an absorbent body arranged within said frame with its edges clamped between said inwardly presented flanges.

2. ln an inling pad, a frame composed of a pair of members, one of which is disposed within'the other, said members being provided with inwardly projecting flanges, an absorbent body disposed within said frame and having its edges clamped between said inwardly presented flanges, and a portion of the outer member of the frame being bent inwardly over the outer portion of the inner frame member.

3. In an inking pad, a frame composed of a pair of members that are substantially E -shape in cross section, one member being arranged within the other and with the horizontally disposed flanges of said members inwardly presented, an absorbent body arranged within said frame with its edges clamped between said inwardly presented flanges, and the inner edges of said inwardly presented flanges being provided with burrs that engage the` outer 'faces of said absorbent body.

4. An inlring pad comprising an absorbent body, sections of fabric applied to the faces thereof, a marginal frame for said body. of absorbent material and the fabric sections thereon, and the inner edges of which marginal frame are provided with burrs that engage said sections of fabric.

5. An inking pad comprising a body of absorbent material, sections of fabric applied to both faces of said body of absorbent material, and a two part frame clamped upon the edges of said body of absorbent material and the sections of fabric positioned upon the faces thereof.

6. The herein described method of producing inking pads which consists in forming a pair of frame members, one of which is adapted to lit within the other, arranging said frame members upon the edge of an absorbent body, and then simultaneously clamping portions of said frame members lupon the edges of said absorbent body, and a portion of one of said frame members upon a portion of the other member.

7. The herein described method of producing inking pads which consists in covering a body of absorbent material with sections of fabric, then applying a pair of cooperating frame members to the edges of said absorbent body of the sections of fabric positioned thereupon, and then applying pressure to said cooperating frame members to clamp the same to each other and to clamp the interposed portions of the absorbent body and sections of fabric thereon.

ln testimony whereof I have signed my name to this specification.

ROBERT H. KEE.
