INKSTAND.

SPECIFICATION forming part of Letters Patent No. 417,373, dated December 17, 1889.

Application filed May 16 1889. Serial No. 311,035. (No model.)

To all whom it may concern.-

Be it known that I, HENRY G. THOMSON, a

citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Inkstands; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereongvhich form a part of this specification,

Figure 1 is a top View, Fig.2 a front side elevation, and Fig. 3 a vertical and transverse section, of an inkstand made in accordance with my invention. Fig. at is a vertical section taken through one of the openings made in the said inkstand, through which access is had to the ink and to receive and support the pen when not in use.

The object of my invention is to provide an inkstand which embraces the desirable features of some of the more expensive inkstands provided with a piston now or heretofore in use, and which can be manufactured and sold at very much less price than those above referred to, owing ,to the slide or piston in my inkstand being sustained in' its bearing by friction and moved by the direct application to it of the hand instead of by mechanism operated by the hand.

In the drawings, A denotes the fount, which is represented as rectangular in top view, although it. may be made in any other suitable shape. Opening through the top of the fount is a vertical passage B, to receive a slide or plunger 0, sustained in position therein by springs a,arranged in chambers 19 in the surface of said passage, said springs and chambers being dovetailed in shape, as shown, so that when the springs are compressed and sprung into the chambers said springs will remain therein, project inwardly beyond the surface of the passage B, and bear with the requisite friction againstthe slide to sustain it at any height within the range of its movement therein.

The top surface of the fount is inclined be tween the slide and its front face, as shown at c, and is there provided with one or more openings d for receiving and sustaining a pen and holder in an inclined position, as shown in dotted lines in Fig. 4, the pen, when in the opening, resting or is projected into the ink, and will consequently be ready for use when required, and being kept wet will not corrode, it being intended that the ink shall be maintained against the top of the ink-chamber by the slide, which can be readily depressed by the fingers to elevate the ink when required and until the ink in the chamber is reduced in quantity to such an extent that the slide cannot be further depressed to raise it, when the slide should be withdrawn from the fount and the chamber replenished with ink.

The inkstand hereinbefore described embraces all the advantages of inkstands provided with plungers as heretofore used, but is stripped of all mechanism for suspending and operating said plunger, which materially reduces the cost of manufacture, and is also less liable to get out of order.

Having described my inventio11,what I claim is In an inkstand, the combination of the fount provided with one or more openings for receiving the pen and sustaining it and its holder, the passage B, leading through its top and into the ink-chamber, the chambers 17, opening into said passage, and the springs 0, supported in said chambers and projecting beyond the surface of said passage, with the plunger supported in said passage by the springs, all essentially as shown and set forth.

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

, HENRY O. THOMSON.
