UNITED STATES PATENT OFFICE.

MATTHEV C. BOGIA, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN HNDLES FOR STAMPS.

Specification forming part of Letters Patent No. 41,597, dated February 16, 1564.

To all whom it may concern:

Be it known that I, MATTHEW C. BOGIA, of Philadelphia, Pennsylvania, have invented a new and Improved Handle for Stamps, Snc.;

full, clear, and exact description of the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

My invention consists of a gum-elastic tube or block fitted to the die of a stamp as set forth hereinafter, the said tube or block being of such a size and shape as to form the entire handle of the stamp, thus presenting a surface of adhesive and at Vthe same time yielding quality, so that but a slight grasp only ofthe hand of the operator is necessary, and so that the abrasion and blistering of the operators hand, which results from the remay be avoided.

1n order to enable others to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of this specification, Figure I is a vertical section, and Fig. 2 a plan view, of my improved handle as applied io an' ordinary hand-stamp.

A is a block or die, of any suitable metal, and on the under side of this block are the letters, figures, or ornaments from which the desired impressions have to be taken. From the center of this block projects a stem, a, over which the gunrelastic tube B is tightly fitted, this tube being of a sufficient length and diameter for being conveniently grasped in the hand of the operator.

In using ordinary stamps-such, for instance, as are employed for marking the envelopes of letters in the post otlices-the rigid wooden handles to which the dies are directly connected are objectionable on acconntof the smoothness and rigidity of the surface, the i'ormerrendering a tight grasp necessary, and the latter' causing such shocks that abrasion and blistering of the palm and lingers of the hand ensues after frequent use'. It will be observed that the stein a penetrates but a short distance into 'the gu 11i-elastic handle B, so that it must have considerable lateral elasticity above the point to which the stem reaches. Vhen the handle, therefore, is grasped in the hand and the die is brought down onto the paper with force sufficient to make the desired mark, the engraved surface of the die will adjust itself to the surface of paper and make an even and perfect impression although at first one edge of the die only should strike the paper. The main advantage of my improved stamp, however, results from the adhesive nature of the gum-elastic, which is such that when grasped tightly in the hand the latter will not slip on the handle at the time the required blow is given, whereas an ordinary smooth wooden handle isapt, if not grasped very rmly, to slip in and blister the hand of the operator.

It will be seen without further description that a stamp with my improved handle requires less exertion to operate and produces a more uniform impression than .those with ordinary Wooden handles. Should an increased lateral rigidity of the handle be required, an additional steril, b, may be screwed onto the end of the stem a, thereby forming, as it were, a rigid core Without detracting from the comfort which the gum-elastic tube atfords to the operator Who has to handle the instrument.

I wish it to be understood that I do not desire to claim,broadly,so constructing a handstamp that the die can yield laterally and vertically independently ot' the handle; but

I claim as my invention and desire to secure by Letters Patent- The gum-elastic tube or block B, iitted to the die as set forth, when the said tube or block is of such size and shape as to form the entire handle of the stamp, for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
