Description
July'15, 1930. E. A. OPPENHEIMER STAMP PAD Filed March 7, 1929 naw/what m Gnu/"ago Patented July 15, 1930 hearse stares" iuiaezi EDGAR A. OPPENI-IEIMER, OF CHICAGO, ILLINOIS STAMP PAD Application filed March 7,
The invention relates to inking pads for rubber stamps, of the type in which ink is fed to the upper surface by a capillary feeder, and itis one object of the invention'to simplify and cheapen the construction of such pads without producing an inferior article, and in carrying out this end, a further aim is to provide a capillary ink feeder in the form of a slab cut from an absorbent mineral in its natural state, said mineral being preferably pumice-stone. This material possesses numerous advantages over materials previously known for this use. There is no chance of warping, it possesses all requisite degree of absorption, it distributes and discharges the ink evenly, possesses an improved stamp-engaging surface, is more easily cleaned, is of less expensive construction, and is indestructible in so far as action of ink upon it, is concerned. i
A further object is to provide a pumicestone ink-feeding slab in which the grain of the stone is disposed vertically with its trans verse area exposed for contact with the rubber stamp, the capillary feeding of the ink being much more effectively carried out when the grain is positioned in this manner.
' A still further object of the inventionis to provide a unique construction and arrangement of parts whereby a frangible ink-feeding slab is held within a shallow metal container in an effective manner and so cushioned that said slab will not be accidentally broken in case the entire article should be dropped.
With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing. 0
Fig. 1 is a top plan view of a stamp pad constructed in accordance withmy invention. 7 Fig. 2 is a vertical transverse. sectional view on line 2-2 of Fig. 1.
In the drawing above briefly described, the numeral 5 denotes a shallow, open-top metal container preferably having a hinged cover 6. Extending over the entire bottom of the container 5 is an absorbent pad 7 of felt or 50 the like, said pad being provided with up- 1929. Serial No. 345,202.
standing portions 8 forming linings for the side andend walls of said container. Within the lined container, is the frangible slab 9 which is out from an absorbent mineral in its natural state. This mineral is preferably pumice-stone and in cutting the slab,
the cuts which form its upper and lower surfaces are preferably formed transverse to the grain 10, so that this grain will stand ver-. tically in the complete article, with its transverse area exposed for contact with the rub-' ber stamp, By positioning the grain in this manner, the capillary action is more efl'ective for feeding the ink from the pad 7 to the surface of the slab.
The slab 9, due to the natural formation of the mineral from which it is cut, possesses very rough edges 11. These edges contact with the lining portions 8 of the pad 7 and portions 12 of the container extend inwardly and constantly press upon said lining portions 8, thereby holding the pad in the container 5 and causing said portions 8 of said pad to tenaciously grip the rough edges 11, r so that the slab 9 will be tenaciously held in place. The pad 7 and its portions 8 also serve to yieldably mount the slab 9 so that breakage thereof will not take place in case the entire article should be dropped.
By employing the novel construction shown and described, a pad is produced which is exceptionally simpleand inexpensive, yet is efficient and in every way desirable. On account of the existing advantages for the. details disclosed, they are preferably fol-' lowed. However, within the scope of the invention as claimed, minor variations may be made.
Best results are obtainable when using a; rather heavy-body ink.
I claim 1. A stamp pad of the type in which ink, l
is fed to the upper surface by a capillary feeder; and capillary ink feeder of said pad consisting of a slab cut from pumice-stone in its natural state.
2. A stamp pad of the type in which ink is fed-to the upper surface by a capillary feeder; the capillary ink feeder of said pad consisting of a slab cut from pumice-stone in its natural state, the grain of the stone being disposed vertically with its transverse area exposed for contact with the stamp.
In testimony whereof I have hereunto affixed my signature.
EDGAR A. OPPENHEIMEB.
