HAN D-STAM P.

SPECIFICATION forming part of Letters Patent No. 506,586, dated October 10, 1893.

Application filed March 15, 1893 Serial No. 466,087. (No model.)

To all whom it may concern.-

Be it known that I, JOHN E. DUNHAM, of

" vention, such as will enable others skilled in the art to which it pertains to make and use 1t, reference being had to the accompanying drawings, which form part of this specificati-on.

Myinvention relates to an improvement in I hand stamps, and it consists in the novel features of construction, hereinafter fully described, and especially referred to in the claim.

The object of my invention is to provide an improved implement of the class described, having a number of independently operated stamps.

Referring to the accompanying drawings, Figure 1, is a perspective View of my improved device. Fig. 2, is a longitudinal sectional view of the same. Fig. 3, is a vertical cross sectional view on line 3-3, of Fig. 2.

The frame or shell of the device consists of the vertical side members A, the ends B, and the Vertical longitudinal partition 0. The end portions B are shorter than the sides, as shown,while the latter are cut upward between their ends so that when the device is resting on the paper to be stamped the implement is in contact therewith only at its four corners. The adjacent faces of the ends B, are shouldered at D, near their lower ends and adapted to move longitudinally between these shoulders are the stems E. The respective upper ends of these stems are projected as at F, the said projections extending directly over the shoulders D, and arranged between the said shoulders and projections are the coiled springs G. Secured to the lower ends of the stems and depending below the ends of the frame are the stems H.

J are bearings projected vertically from the sides A and partition 0, and pivoted between these hearings are the cam levers K, having the straight edges L, which bear upon the upper end of stems E when the said lovers are in a vertical position and the stems are raised. For depressing any one of the desired stamps the lever arranged immediately over the same is turned down, as shown in Fig. 2, thereby forcing its cam surface against the stamp stem and depressing the same so as to make an impression on the paper or article to be marked.

I here show only two stems arranged in the casing but it is apparent that any number of Stamps may be assembled and operated with case. By means of the coiled springs the stems are returned from contact with the paper as soon as the levers are raised thereby automatically putting them in position for the next operation.

By means of the construction here shown and described it is possibleto arrange a great number of stamps together and to use either one of them independently of the other.

Having thus described my invention, what I claim, and desire to secure by Letters Patout, is

An improved hand stamp comprising a frame, one or more longitudinal partitions therein, depressible stamp stems within the frame, bearings projecting vertically from the partition and the frame, and cam levers pivoted between the said bearings for the purpose of depressing the said stamp stems, substantially as shown and described.

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

JOHN E. DUNHAM.
