LEON P. LOWE, OF SAN FRANCISCO, CALIFORNIA.

SELF-ENKING RUBBER STAMP.

Application filed. September 21, 1908.

To all whom it may concern:

Be it known that I, LEON P. Lows, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Self-inking Rubber Stamps, of which the following is a specification.

This invention relates to improvements in self inking rubber stamps for printing with rubber type and an absorbent ead.

From a number of such stamps, especially when they are of uniform size and shape, it is at present ditlicult to identify quickly the particular stamp wanted.

The object of the present invention is to provide an. improved construction, avoiding this difficulty.

In the accompanying drawing, Figure 1 is j a side view of a hand stamp constructed in accordance with my improvement; Fig. 2 is an end view; Fig. 3 is a sectional view on the line 33 of Fig. 1; Fig. A is a broken longitudinal sectional view showing a card partly in position; Fig. 5 is a broken perspective view of a modification of the invention.

Referring to the drawing, 1 'ndicates the stationary irame of the stamp, having the usual pad 2. 3 indicates the type holder, pivotally mounted in the usual manner upon a shaft 4, the ends of which slide in vertical slots 5, and are connected to the arms 6 of a yoke 7 adapted to be depressed by a handle 8. All of the above is of the usual construction. Said handle slides upon a guide rod 9, but instead of securing this guide rod centrally to the top plate 10 of the frame, I attach it to a cross head 11, the ends of which are secured to the sides of said top plate, so

' that said top plate isentirely free and unobstructed within its periphery. It is thus possible to secure upon said top plate a card or piece of paper 12 having formed thereon the impression made by the stamp, thus enabling said stamp to be readily identified and selected from a number of other stamps of Specification of Letters Patent.

like form and size. To conveniently hold such card or paper, the cross head is here shown as cut out to form tongues 13, which engage the longitudinal edges of the card or paper. A card or piece of paper can readily be inserted in position with its edges underneath said tongues by slightly rolling or bending the paper, as shown in Fig. 4.

In the modification shown in Fig. 5, one of the arms of the yoke is enlarged transversely and formed with slots 14, through which the end of the card or paper can be inserted and passed beneath the tongues. It is preferable that this slot should be slightly above the level of the tongues so that the card will not slip out of position after once having been inserted.

l1 claim 1. In a self-inking rubber stamp, the combination of a frame, an absorbent pad supported thereby, rubber type, means for mov ing said type from said pad, and a guide for said means secured to said frame only at marginal portions thereof, the interior of the to of said frame being free and unobstructec, whereby an index may be secured on said top, substantially as described.

2. In a self inking rubber stamp, the combination of a frame, an absorbent pad supported thereliiy, rubber type, means for mov ing said type from said pad, a central guide rod for said means, and a cross head secured to said guide rod, the ends of said cross head being secured to said frame only at marginal portions thereof, the interior of the top of said frame being free and unobstructed, whereby an index may be secured on said top, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
