Application filed To all whom it mar/y concern:

Be it known that I, WILLIE Snow, a citizen of the United States, residing at Devils Lake, in the county of Ramsey and State of North Dakota, have invented new and useful Improvements in Hand-Stamps, of which the following is a specification.

Hand stamps for canceling postage stamps and for marking generally have a rigid connection between the handle and the die, hence when using the same the matter to be printed does not show to advantage because of unequal distribution of the pressure.

The purpose of the present invention is to equalize the pressure applied when using the stamp so as to insure a plain impression being made since every part of the die receives an equal pressure.

The invention provides a novel connection between the die and handle, whereby the die is at all times held in operative position and provision had for adapting the same to the surface so as to equalize the pressure and insure a plain impression, which is highly essential.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawings, and pointed out in the appended claims.

Referring to the drawings, forming a part of the specification, Figure 1 is a vertical central section of a hand stamp embodying the invention. Fi 2 is a horizontal section on the line 5-5 0 Fig. 1. Fig. 3 is a View of the stamp inverted. Fig. 4 is a perspective view of the member of the connection between the die and handle provided with the ball.

Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawings, by the same reference characters.

The hand stamp comprises a die 1, which is oblong, although it may be of any shape and construction according to the matter to be printed. The handle 2 may be of any construction and is of approximately spherical form to be conveniently grasped in the hand.

The connecting means between the handle and die are such as to admit of said parts having a relative movement, whereby the printing surface of the die may receive a speclficationof [Letters Patent.

uniform pressure throughout its length and move to adapt itself to the relative position of the surface to receive the imprint. The connecting means comprises a rod 3, a clamp 4, and a stem 5 having a ball 6. The stem 5 is threaded into the die 1 at a central point or may be secured thereto in any manner. The ball 6 at the upper end of the stem 5 has a circumferential groove 7 which receives jaws 8 at the lower ends of the members of the clamp 4. The clamp 4.- is elongated and comprises similar members or sections, which are held together when the clamp is inserted in an opening 9 formed in the shank of the handle 2. When the members of the clamp 4 are brought together the jaws 8 fit within the groove 7 of the ball G and embrace opposite sides of the ball, thereby gripping the same while admitting of a limited play between the clamp and stem, which is essential to allow for relative movement between the die 1 and handle 2 to attain the objects herein stated. A threaded opening 10 is formed in the upper end of the clamp 4 and receives the lower threaded end of the connecting rod 3. The connecting rod passes through an opening 11 formed axially of the handle and in line with the opening 9. The upper end of the connecting rod is enlarged to form a head 12, which has a groove to receive the point of a screw driver or like tool, whereby the connecting rod may be screwed into or out of the threaded opening 10. A helical spring 13 is interposed between the lower end of the handle 2 and the die 1 and holds said parts in given position. Caps 14 are fitted to the lower end of the handle 2 and the upper side of the die 1. and receive the ends of the helical spring 13, whereby the latter is retained in proper position. The caps 14: are centrally apertured to receive the clamp 4 and the stem 5.

When the parts of the stamp are assem bled the helical spring 13 is subjected to pressure, whereb Y a tension thereon is created, said saring serving to hold the die 1 and the handle 2 in given position and. admitting of the .die having relative movement when the stamp is in operation, so that the pressure exerted may be evenl distributed throughout the printing sur ace of the die to the end that a plain impression mt? be obtained.

*rom the foregoing description, taken in connection with the accompanying drawings, the advanta es of the construction and of the method 0 operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the invention what is claimed as new, is

l. A hand stamp comprisin a die, a handle having an axial opening t Iierein, a stem secured to the die and provided at its upper end with a ball, a sectional clamp havin jaws embracin opposite sides of the bal, the sections 0 said clamp being held together by the walls of the opening formed in the handle into which the said clamp is inserted, and a connecting rod for securing the clamp to the handle.

2. A hand stamp comprising a die, a handle having an axial opening, a stem having one end attached to the die and provided at its opposite end with a ball, a sectional clamp formed with jaws embracing o posite sides of the ball and held together y the walls of the opening formed in said handle after the clamp has been inserted therein, said clamp having a threaded opening in its upper end, and a connecting rod having its lower end threaded to engage the threaded end of the clamp and hold the parts in proper position.

3. A hand stamp comprising a die, a bandle having an opening formed centrally therethrough, a stem secured to the die and provided at its upper end with a ball in which a circumferential groove is formed, a clamp comprising similar sections having jaws at their lower ends to enter the groove of the ball and embrace opposite sides of the latter, said clamp having a threaded opening at its upper end and inserted in the opening of the handle and having its sections se cured thereby, a connecting rod inserted in the opening of the handle and having screw thread connection with the crank, and a helical spring inserted between the handle and die.

In testimon 1 whereof I afiix my signature in presence 0" two witnesses.
