IMPROVEMENT 'IN INK-PADS.

Specification forming part 01 Letters Patent No. 135,949, dated February 18, 1873.

To all whom it may concern:

Be it known that W6, HENRY It. TOWNE and WARREN H. TAYLOR, both of Stamford, in the county of Fairfield and State of Connecticut, have invented a new and useful form of Inking-Pad, for inking the surfaces of canceling, dating, and other stamps and we do hereby declare the following to be a full and of the amount of ink given off from, its surface to the type.

The construction of our improved pad will be easily understood by reference to the anneXed drawing, in which- Figure I is avertical transverse section of a complete pad. Fig. II is a plan and elevation of the clamping device. Fig. III is aplan of the adjusting-wheel.

Similar letters of reference indicate corresponding parts throughout.

A is the metalshell or case of the pad. B is the movable piston. O is the adjustingnut. D is the adjusting-wheel. E is the clamping-wire. F is the clamp. G is the clamp-screw. H is the cover or inking-surface of cloth or leather. I is the groove to contain the clamp-wire E. J is the interior space, to be filled with the elastic stuffing. K is the filling'screw'or stopper.

To'prepare the pad 'for use, the space J is filled with wool or other elastic substance sat- .urated with ink, and the cover H, of chamois,

-- ening the cover H to the case A.

It will be readily understood that the amount of ink given off from the surface of the cover H will depend largely upon the force with which the stuffing containing the ink (which fills the interior space J of the pad) is pressed against the under side of the cover; and this pressure may be regulated by moving the piston B up or down within the case, which is done by simply turning the adjusting-wheel D in the under side of the pad. The wheel D is securely attached to the nut C the interior surface of the latter is threaded, and into it is screwed the stem of the piston 13. The piston being prevented from turning by a suitable feather or key, it is evident that the revolution of the nut O, by

means of the wheel D, will force the piston upward in the case, thus pressing the stuffing against the cover, while the revolution of the nut in the opposite direction will retract the piston and relax the pressure on the stuffin g. In this manner, by properly adjusting the screw, the amount of ink given off by the pad may be regulated to a nicety.

Should the ink with which the elastic stuffing is saturated become exhausted, a fresh supply may be introduced by inverting the pad, removing the plug or stopper K in the bottom of the piston, and pouring ink into the interior of the pad through the opening thus made.

When the cover H is worn out it may be replaced by a fresh one.

When the ends of the wire E are drawn together by the clamp F, the material of the cover H is compressed between the wire E and the 'sides of the angular groove I in the case,thus holding the cover in the most secure manner.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination, in an inking-pad, of a case provided with a flexible cover, an adjustable piston, and an elastic stufiing.

2. The combination, in an inking-pad, of the case A, piston B, nut O, flexible cover H, and elastic stuffing filling the interior space J.

3. In an inking-pad, the combination of the flexible cover H, the angular groone I, and the case A, piston B, nut G, flexible cover H, the clamping-wire E, arranged snbstantiztlly clamping-wire E, and. elastic stuffing filling as and. for the purposes described. 1 the space J.

4. In combination with the subject'rnatter HENRY R. TOWNE. of the first claim, the induction-orifice closed W. H. TAYLOR. by plug K. Witnesses:

5. The combination, in an inking-pad, of A. W. RICHARDS,

the several parts hereinbefore described-"512., E. T. GREENE.
