INKSTAND.

SPECIFICATION forming part of Letters Patent No. 563,615, dated July 7, 1896.

To all whom 2325 may concern.-

Be it known that I, FRANCIS B. PRATT, of Canton, in the county of Madison and State of Mississippi, have invented certain new and useful Improvements in Inkstands, of which the following is a full, clear, and exact description.

This invention relates to inkstands of the feeding-reservoir type; and the object is to provide a simple device of this character that may be easily clean ed and filled and in which but a small quantity of ink need be exposed.

I will describe an inkstand embodying my invention, and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of an inkstand embodying my improvement. Pg. 2 is a side elevation thereof, and Fig. 3 is a vertical section.

Referring to the drawings, A designates the body of the inkstand, having an inlnwell a, and a supply-well a, formed in the top of the body portion forward of the ink-well.

The wall of the supply-well is preferably flared outward and upward, and its bottom is considerably above the bottom of the inkwell. From the bottom of the supply-well a feeder-duct a extends downward at an incline and communicates with the ink-well at its bottom. An air-duct a leads outward from theupper portion of the ink-well. The duct a is here shown as leading into the upper portion of the supply-well.

-Within the upper portion of the ink-well an internally-threaded annular flange a is formed, and is designed to be engaged by the exterior thread of a plug A. The plug A has sufficient length to extend to the bottom of the ink-well when screwed down, and its upper end is provided with a milled flange 0.

Application filed December 14, 1895. Serial No. 572,178. (No model.)

to provide a good grasp for a persons fingers while rotating the plug.

The plug A is made in the form of a cup closed at the bottom and open at the top, and is designed to receive a wet sponge or other material for cleaning pens. The plug may be entirely removed when it is desired to clean or fill the ink-well. It is obvious, however, that the well may be filled through the duct (L as the air will escape through the duct a and allow the ink to rise in the well. It is obvious that a downward movement of the plug will force ink through the duct a to the well a, which may be filled to any desired extent.

The inkstand and plug may be made of any desired material, and I find hard rubber well adapted for the purpose.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An inkstand, comprising a body portion having an ink-well, a supply-Well, a feeder duct leading from the bottom of the ink-well to the bottom of the supply-well, and an airduct leading outward from the upper portion of the ink-well, and a plug movable vertically in the ink-well and forming a cup for pencleaning material, substantially as specified.

2. An inkstand, comprising a body portion having an ink-well, a supply-well, a feederduct leading from the bottom of the inlnwell to the bottom of the supply-Well, and an airduct leading from the upper portion. of the ink-well into the supply-well, a cup-shaped plug closed at the bottom and open at the top, having screw thread engagement with a flange in the upper end of the ink-well, and a milled flange on the upper end of the cupshaped plug, substantially as specified.
