lNKSTAND.

SPECIFICATION forming part of Letters Patent No. 517,384, dated March 2'7, 1894.

Application filed November 29. 1889. Serial No. 331,862. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES EDWIN J EW- ELL, of Toronto, in the Province of Ontario and Dominion of Canada, have invented certain Improvements in Inkstands, of which the following is a specification. I

My invention relates to an inkstand in which the cup or funnel provided with a dip-tube is mounted in and sustained by a flexible diaphragm closing the top of the ink-containing body so that when the diaphragm is depressed by a pressure on the funnel it causes the air rigid ink-containing body or vessel made of glass or similar material and provided in the top with a single mouth or opening.

B represents a stopper made of india rubber or equivalent highly elastic material. It is adapted to fit snugly within and tightly close the opening in the top of the body so that although held in position by friction it may be adjusted vertically to effect the compression of the air within the body. The stopper is constructed as shown of hollow form with a large interior space and with a thin top wall or diaphragm, I), having sufficient rigidity to stand normally in the position shown, but adapted to be easily depressed as indicated in dotted lines.

O represents the funnel or ink-cup made of glass or other suitable material and provided with a dip-tube, c, fitted tightly through the diaphragm b, and extending downward into the body of ink. The tube and funnel are preferably formed in one piece as shown, and provided with annular flanges, as shown, or otherwise secured to the diaphragm which serves as the sole support for the funnel and the same as those in Fig. 1.

tube. When the parts are in their normal position the ink stands, as shown, at a common level in the body and tube. A slight downward pressure applied to the funnel by means of the pen or otherwise, causes it to sink and depress the diaphragm, as shown in dotted lines, the effect of which is to compress the air within the body and thereby force the ink upward through the tube into the funnel. When the funnel is relieved from pressure the parts assume their original position and the ink descends the tube. As the ink is consumed the stopper is from time to time turned downward within the body in order that the contained air may act in the proper manner to effect the elevation of the ink to the funnel. As the stopper is permanently lowered the dip tube may be slipped upward from the elastic diaphragm if required, so that its lower end will stand normally at a proper distance above the bottom of the body.

It is to be observed that my entire structure consists of but three pieces, the rigid body, the stopper having the flexible portion or diaphragm held in frictional contact with the body and the funnel sustained Wholly by the diaphragm.

Referring to Fig. 2, the parts are essentially In this instance, however, the body, A, is provided with aproj ecting neck or mouth at the top, and the stopper made of hollow form and having a yielding diaphragm as before, is adapted to fit frictionally over and around the neck of the body. The funnel provided with the dip tube is fitted through and sustained by the diaphragm as before, so that when depressed the funnel carrying the diaphragm downward 9o depresses the air and elevates the ink in precisely the same manner as in the stand first described. The stopper is in this instance provided with an annular upturned flange, 19 which serves to receive and retain any ink 5 which may accidentally be carried over the top of the funnel. This flange is of course applicable in the same form and manner to the stopper shown in Fig. 1.

I believe myself to be the first to provide [00 an inkstand in which a yielding stopper serves as the sole support for the ink-receiving funnel, and has a yielding diaphragm to compress the air upon the ink. I also believe myself to be the first to combine with an ink-receivin g funnel a yielding diaphragm which closes the top of the body and which is vertically adjustable to compensate for variations in the quantity of ink contained in the body.

Having thus described my invention, What I claim is 1. As a new article of manufacture, the attachment for an ink bottle consisting of a hollow elastic stopper with a central yielding diaphragm, and the funnel provided with a dip-tube passing tightly through and sustained wholly by the diaphragm: whereby the attachment is adapted to hold itself in place on and tightly seal the mouth of the bottle, and to feed ink to the funnel when the latter is depressed.

2. In an inkstand, the combination of the ink-containing body, the yieldingstopper, provided with the flange b to receive overflowing ink and the funnel and dip-tube, the latter extending through, and supported by, the stopper.

In testimony whereof I hereunto set my hand, this 28th day of October, 1889, in the presence of two attesting witnesses.

CHARLES EDWIN JEWELL.
