lNKlNG-PAD.

SPECIFIGATION forming part of Letters Patent No. 672,120, dated April 16, 1901.

Application iiled April 28, 1900.

To a/ZZ whom it may concern:

Be it known that I, FREDERICK CARL, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Inking-Pads, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a central vertical section of an inking-pad embodying my improvements. Fig. 2 is a section of the pad proper or ink absorbing and delivering part. Fig. 3 is a side view of the clamping-ring detached. Fig. 4 is a side view of the base part detached. Fig. 5 is a bottom view of the complete device. Fig. 6 is a top view of the ink-absorbing felt detached. Fig. 7 is a bottom view of the pad-supporting plate detached. Fig. 8 is an edge view of the same. Fig. 9 is a plan view of the base-rim. Fig. 10 is a plan View of the clamping-ring detached. Fig. 11 is a section, and Fig. 12 is a top View, of a modified form of the inking felt pad.

In the drawings, A indicates the bed-piece or base. It is preferably made ring-like in form, one side being cut or broken, as shown. at a, and the ends at the cut being suitably remote from each other. The outer surface' at a' is slightly tapering for a purpose to be described. At a2 there can be a slight bead at the bottom to serve as a stop and to widen the bottom surface. Near the upper edge and on its inner side it has a horizontal ange as. The vertical part extending up is made tapering in the form of a flange, as at a4. l

The pad proper or inkabsorbing and sup plying part is indicated by C. This is composed of a thick mass of felt, which in the construction shownin Fig. 1 and others eX- tends continuously from the top surface c to' the bottom surface c. This thick disk'of feltv is cut at the periphery to a suitable depth, asI a half-inch or more, as shown at c2.

D is a suitable dexible securing means or jacket for the felt or other body of the pad. In its preferred form and as illustrated it consists of a ring-like strip of strong woven fabric, such as canvas, the inner diameter of which is much less than the diameter of the felt disk. This fabricis placed in the cut at c2 and secured by one or more rows of stitches,

Serial No. 14,772. (No model as at d, and extends outwardly from the felt.

A felt body of this sort can be secured to the base in any of a number of ways. As shown, I employ a felt-supporting plate or disk B. This is of a diameter somewhat smaller than that of the iiange a4 of the base-rim A and is adapted to rest upon the horizontal liange a3. Between the plate B and the base A are interposed springs E, which preferably are made and arranged as shoWn-that is, of curved flat elastic plates and each riveted at e to the plate B and having its free ends e' placed so as to rest upon the flange a3. The outwardly-extending woven-fabric band or jacket Dis adapted to be turned down and snugly fitted against the outer flaring surface a of the base, and after the pad is put in place and this band is thus arranged the clamping-ring F is slipped downward over the fabric, and as it moves down it tightly grips the fabric and stretches it, drawing the felt down firmly. The split base-ring yields sufficiently to allow the proper downward movement of the ring F, and its elasticity insures that the grip of the rim upon the fabric and the pad shall be firmly retained.

There are numerous advantages incident to a construction and arrangement of the parts such as I have shown and described and which will be fully understood upon acomparison with earlier devices-for instance, such -as I have shown in my application, Serial No. 716,776, filed the 13th day of May, 1899. I

have in the present instance succeeded in providing a pad which shall receive the rapid blows of a postmarking and stamp-canceling stamp without imparting shocks to the hand Another important advantage incident to the use of the present device lies in the exposure of the felt surface at the top without the employment of a woven thread fabric such as has been generally employed for the purpose of holding the felt in proper position.

IOO

A body of felt, such as that at C, is not liable to be cut or marled by the blows of the stamp, which, as is well known, is formed with sharp cutting-dies and with a sharp outer ring which is expected to receive ink and print circles upon the envelops or other articles. By attaching the woven fabric D to the peripheral part of the felt I am permitted to use a very strong cloth, such as can vas,which could not be employed if it were to lie over the upper surface of the pad, because ofits being impervious to ink. Moreover, by following this course I can make the pad reversible, and thus insure a use practically twice as prolonged as where one surface only is available. The fabric D is so situated as to protect the stamp from coming in contact with the metal of the base. The clamping-ring F is made as thin as possible, and the pad is expanded laterally, so that there is practically no liability of accidentally striking any of the metal parts with the stamp.

The modified pad shown in Figs. Il and 12 illustrates that instead of making a cut in the periphery of a thick mass of felt to receive the attaching fabric two somewhat thinner pieces can be used and stitched to the opposite sides of a strong-cloth holder, and many of the purposes of the invention can be attained with such a pad.

In several respects there can be modification without departing from the characteristic features of the invention. rPhe resiliency can be provided by employing rubber blocks in place of the metal springs E, or springs of either sort can be dispensed with and still retain a superior pad if it has the exposed felt at its upper operative side with an att-aching device secured to the pad at points below the top surface thereof or in such way as to hold the felt firmly and yet leave it exposed on the top.

Instead of the woven fabric D other forms of attaching devices can be used, as a series of cords or threads or a thin light felt or other equivalent.

While I have shown and described the basering A as split and the inclosing device or ring F as solid, it will be understood that there can be inversion in this respect and the part F can be made elastic and expansible and serve for holding the felt pad firmly in position.

What I claim is- 1. An inking-pad, having at its upper op` erative side a mass of exposed felt, an attaching fabric secured to the periphery of the felt, and a base to which the fabric is secured.

2. An in king-pad having at its u pper operative side a mass of exposed felt, an attaching fabric inserted into the body of the felt at a place between the top and bottom surfaces of the felt and secured therein, a supporting base or bed, and means for securing the fabric to the base, substantially as set forth.

3. An inking-pad having at its upper, operative side, an exposed mass of reversible felt, a fabric secured to the periphery of the felt, a bed or base and means for securing the fabric to the base in whichever position the felt may be turned, substantially as set forth. Y

4. An inking-pad having a base, a plate tted loosely to the upper part of the base, a reversible felt disk on the plate and a fabric secured to the periphery of the. felt disk and means for fastening the fabric to the base, substantially as set forth.

5. In an inking-pad, a base having suitable means for supporting an ink-holding material, and an inclosing device such as a ring, one of said parts being elastic and one of said parts having a tapered surface widening vertically, in combination with an ink-holding pad ou said base and a pad-attaching device secured positively to the pad at points below its upper surface and confined between said base and inclosing device.

7. In an inking-pad the combination of the elastic split ringA having flared external surfaces, the loosely-supported plate B on said base, the ink-absorbing material C on said plate, the fastener D with its edge against the ring-base A, and the solid ring F adapted to be slipped along the flaring base and to contract the latter and bind the parts together.

8. In an inking-pad, the combination of the elastic split-ring base having a daring external surface and a supporting rib or bead, the loosely-supported plate on said bead, the inkabsorbing material upon said plate, the fabric jacket with its edge against the said ringbase, and the solid ring adapted to be slipped along the said flaring base and to contract the base and bind the said parts together, substantially as set forth.

9. In an inkng-pad, the combination of the split-ring base having a stop on its outer face, said face being tapering, and having at its upper edge the flange and the inwardly-projecting bead, the looseplate resting on the said bead, the ink-absorbing material on the said plate, the jacket, and the ring adapted to move vertically along the tapering face of the split-ring base, while in contact with the edge part of the jacket, whereby it contracts the base and puts the jacket under tension, substantially as set forth.
