SPECIFICATION forming part of Letters Patent No. 608,887, dated August 9, 1898.

Application filed September 9, 1897. Serial No. 651,088. (No model.)

To all whom it may concern.-

Be it known that I, JONATHAN H. MELVEN, of St. Louis, Missouri, have invented a new and Improved Inking-Pad, of which the following is a full, clear, and exact description.

My invention relates to an improvement in inking-pads; and it consists of certain features of construction, which will be hereinafter described and claimed.

The invention also comprises certain novel features of construction, which will be hereinafter described, and particularly pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a-perspective view of the inking-pad. Fig. 2 is a longitudinal sectional View showing the novel features of the device. Fig. 3 is a top plan view showing various parts of the device broken away, so as to show those beneath; and Fig. 4 is a side elevation of a portion of the base and the threaded collar which receives the closingcap.

The object of my invention is to provide means by which an inking-pad may be supplied with fresh ink, which shall be applied at the bottom of the pad and gradually soak upward. The pad may be made in any of the ordinary shapes and sizes and is preferably inelosed in a box A of the usual construction, as shown in Fig. 1, the box having a hinged cover A, adapted to close over the top of the pad and prevent its too rapid drying out. In the bottom of the pad is formed an aperture surrounded by a collar F, which extends upwardly-and is threaded to receive a screwcap F. The collar F may be made as a part of the bottom or be secured thereto. The bottom immediately surroundingthe collar is preferably countersunk sufficiently to receive the flange at the bottom of the screwcap F, so that when the cap is in position its flange will be flush with the bottom surface of the box or a little above it.

Within the box A is a block B, which may be formed of wood, plastei' cf-paris, or any suitable material. with ink-reservoirs, which may consist of round holes I) or of grooves 19, as desired, or

venient or usual manner, which is fixed to the block B, is made enough The block B is provided collect in the reservoirs b and b.

of both in combination. These reservoirs are slightly recessed below the surface of the block and are adapted to receive and hold surplus ink. The block B has a central aperture slightly larger than the collar F, and a collar G is formed to closely fit this aperture in the block and extends upward to a point even with the top of the block. This prevents the ink within the reservoirs b or Z) from escaping into the space surrounding the collar F A screen 0, formed of a thin metal plate or a small piece of Woven wire, as found. preferable, is placed above the block B. This screen serves to hold the absorbent pad D so that it will not sink down into the ink-reservoirs. The pad D is formed of felt or any usual material which will readily absorb and hold the ink and is covered with one or more layers of cloth.

As shown in the drawings, a layer E of cloth covers the top of the pad, and a second layer E is stretched over the pad about the edgeseand beneath the bottom surface of the block and is secured to the block in any con- The collar G,

larger than the collar F of the boxAto leave space for a spiral spring II. This spring bears against the lower side of the screen 0, holding it slightly. raised above the block B, thus making it possible to easily fill the inkreservoirs.

The cap I, which is screwed into the threaded opening in the bottom of the box A, is of the usual form, having its bottom or inner end closed by a central longitudinalpartition f,'by which it may be engaged for screwing it in or out. This partition may be engaged bythe end of a penknife or with any other suitable tool.

I In filling the ink-reservoirs the pad is turned bottom upward, the cap I removed, and ink poured in at the opening in the box A and block B. The ink will spread between the pad D and the block B, filling the orifices in the screen and the space betweenthe screen and block. The cap F is then replaced, and the pad is turned right side up. Any surplus ink which may be in the pad will then The collar G will prevent the ink running from these reservoirs into the opening surrounding the collar F. In this manner the ink is applied to the bottom of the pad and gradually soaks to the top, thus insuring that the pad shall not beexcessively inked at the time when it is supplied with new ink, as is common Where the ink is spread upon the top surface of the pad. Moreover, the surplus ink thus supplied to the ink-reservoirs Will be gradually absorbed by the pad D, and the pad will not require as frequent filling as the ordinary pad.

It is evident that Where the pad is of such a size as to warrant it the number of fillingopcnings may be increased, the number used being proportioned to the size of the pad. The pad is adapted to use any kind of stamps, Whether rubber or metal.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- An inking-pad, comprising a box having an upwardly-extended threaded collar attached to its bottom, a block surrounding said collar Within the box and provided with ink-reservoirs in its upper surface, a collar fixed in the block surrounding the threaded collar and extending to the top of the ink-reservoirs, a spiral spring in the annular space between the two collars, a screen covering said block, an absorbent pad above the screen, and a closure for the threaded collar, substantially as described.
