INKSTAND.

SPECIFICATION forming part of Letters Patent No. 650,046, dated May 22, 1900.

Application filed August 25, 1898. Serial No. 689,466. (No modelJ To aZZ'whom it may concern.-

Be it known that I, PETER D. HORTON, a citizen of the United States of America, re siding in the city of Oakland, county of Alameda, and State of California, have invented certain new and useful Improvements in Inkstands, of which the following is a specification. Y

My invention relates to improvements made in reservoir-inkstands; and the same consists in certain novel parts and combination of parts, as hereinafter described and claimed and as illustrated in the accompanying drawings, forming part of this specification.

Figure 1 of the drawings is a longitudinal section in perspective of aninkstand constructed in accordance with my said invention. Fig. 2 is a plan or top view of a con struction in which the inkstand is provided with a sponge-cup and a water-reservoir in addition to the ink-Well and its fountain or reservoir. Fig. 3 is a longitudinal section through the ink-reservoir and the elastic top. Fig. 3 is a sectional view of the elastic top removed from the reservoir. Fig. 4 is a sectional View of the feed-tube removed from the reservoir. I

A indicates the body of the inkstand, and A a well or cup in the top of relatively-small size to contain ink in sufficient quantity for charging the pen-point when the same is dipped into the cup.

A is a Well or receptacle to contain a body of ink and forming a reservoir for supplying the well A.

The tops of the two receptacles A A are on the same level, but the bottom of the larger one is situated below the bottom of the smaller one.

B is a flexible tube having one end 17* resting on or set in close proximity to the bottom of the reservoir A and the other end b inserted through the wall or partition that separates the receptacle A from the reservoir. That end of the tube which is set through the partition is fixed in place at suflicient height from the bottom of the receptacle A to provide a proper depth of ink or fluid in the receptacle, the function of thetube being such that it acts both as a supply-passage for the ink or fluid from the reservoir and as an overflowpassage through which any excess of fluid above that point will flow back into the reservoir, thereby preventing the contents of the well from overflowing or from exceeding a given depth.

The reservoir A is closed by a top or cover 0, constructed with a heavy flange O, which flts tightly into the reservoir, and a projecting rim G which makes a close fit against the flat margin surrounding the reservoir and in connection with the tight] y-fitting flange insures an air-tight joint between the stand or body containing the reservoir and the cover. The central portion 0 is made thinner or more flexible than the body of the cover at the surrounding flange, and the flange C is made somewhat larger in diameter than the reservoir A so that when placed in the opening and pressed down into place the cover will close the top; but the compression of the flange will cause the more flexible center portion 0 to assume an arched or crown-like form, by virtue of which that part will both readily yield to pressure applied from above and will return to position again as soon as the pressure is removed.

D is an air-vent in the cover 0, through which pressure of the atmosphere is admitted to the reservoir and an equilibrium between the exterior atmosphere and the interior space of the reservoir above the fluid contents is es tablished.

The operation of transferring the ink or fluid from the reservoir to the Well A through out of rubber and the tube B can be made of the same material or substance. If metal be substituted for rubber, care should be taken to secure an airtight joint between the cover and the rim of the reservoir. in that case will be suitably bent to turn its lower end perpendicularly downward against the bottom of the reservoir. The lower end The metal tube portion of the tube is-slittedor cutaway oli prevent the end-from being choked or cl9gged with the heavy or thicker portion of the contents at the bottom ofthe receptacle. 7
