CUR'rrss EUGENE SNYDER, oF soUTH VALLEYQEWYQBK HAND-STAMP.

Application filed February 7, 1914. Serial No. 817,285.

Specification of Letters Patent.

Patented July respective of the angle of the handle, andl further the construction of the device Whereby the handle Will be connected with the stamping face or die so as to permit of an axial application of force against the die to form a consistent impression against the work.

Another object of the invention is the provision of a stamp of this character in which the mating or Companion parts thereof may be r'eadily assembled.

With these and other objects in view, the

invention consists of certain novel features of construction, combination and arrangement of parts, as will be' hereinafter de-' a Vertical section therethrough.

The stamp comprises a die 1 having a flat 'lower stamping surface 2 and a Vertical lug. The said die is provided with a vertical passage 4, in which is mounted a metallic bearing block 5 having a curved upper surface 6, whose walls merge into cor`` rcspondingly curved surfaces 7 of the lu' 3 so as to define with said surfaces a socketor the reception'of a spherical head 8 on a stock 9 of a handle 10.

The surface 6 of the bed block 5 is located at a point above the relatively broad flat upper surface 11 of the Vertical lug 3 and surrounding the lug 3 and the adjacent lower portion 12 of the stock 9 is a spring 13 having a substantially convolute upper portion in which one or any suitable number of its convolutions may be closely eng-aged around the stock 9 below the enlarged portion 12 thereof to thereby hold the sprin against sliding movement on the stock an to cause the pressure of the spring to be applied against the surface 11 of the Vertical lug 3, normally holding the latter approximately at right angles to the direction of the stock 9. The lower portion of the spring 13 is preferably provided with a series of convolutions, each having the same diameter so as to maximize the equalizing pressure of the spring against the' stock and at the same time permit the stock to be properly rocked and to assume a proper flat contact With the work when the stamp is moved into stamping position. The stock of the handle has secured thereto a suitable han- 4,

dle 15.

From the construction described, it is seen that the different parts of the device. -may be associated with each other with considerable rapidity during the manufacture of the article. Thestock of the ihandle may be first extended throu h the passage 4 in the Vertical lug 3 until t e spherical portion 8 is brought to bear against the surfaces 7 of the lug 3. The bed block 5 is then driven into the passa-ge 4 and the stamping membei' or surface 2 may be then screwed at 4' or soldered to the Vertical lug 3 and all of the parts seourely held in connected positions. It is of course understood' that after 'extending the lower convolutions of the spring 13 below the point of bearing of the spherical head 8 with the die the latter is more propcrly supported at a position at right angles to the direction of the stock 9 and the purpose of the s ring as a means to permit the member or sur ace- 2 to be brought into flat cngagement with the work is materially benefited.

I claim 2- A hand-stamp comprising a die having mounted thereon a projecting lug having a central passage, a block mounted in the passage and having a curved upper surface, the walls of the passage being extended above the Curved surface of said block and curved thercfrom and defining therewith a socket, a stock having a spherical head mounted in the socket so that the die is adapted for rocking movements on the stock, and a spring between the stock and the die.

In testimony whereof I affix my signature in presence of two witnesses.
