UNITED STATES AUGUSTUS P. GRIFFING, OF EAST CAMBRIDGE, MASSACHUSETTS.

INKSTAND.

Specification forming part of Letters Patent No. 34,299, dated February 1 1, 1862.

To all whom it may concern:

Be it known that I, AUGUSTUS P. GRIFF- ING, a citizen of the United States of Amer- Y ica, and a resident of East Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful 1mprovement in Inkstands; and I do herebydeclare the same to be fully described in the following spcciication and represented in the accompanying drawings, of which- Figure l is a top view of an inkstand as constructed with my improved cap. Fig. 2 is a transverse section of the same. Figs. 3 and 4 are separate sections of the two parts of the cap.

The said cap is made in two parts A B, each being a cylindrical hollow 4vessel or its equivalent. One-viz., the upperis arranged concentric with and so as to screw down upon the periphery of the other, such periphery being constructed with a male screw a, formed on it in correspondence with a female screw b, formed within the inner cylindrical surface of the outer part A. The inner part B may be separate from the body C of the inkstand and be cemented upon the neck c thereof, or it may be made in one piece lwith the said body or neck. Eccentrically through the top of the part B there should be made a mouth or hole d, which, if desirable, may be furnished with a short neck e to extend around and above it. Another hole f, having a diameter equal or about equal to that of the hole e, is made through The top of the upper cap or part A and with its center at the same distance from the axis of the two partsA B as is the center of the hole c, the two holes being so arranged in their respective parts A B as not to be in conjunction (or one directly over the other) when the part A is screwed down closely `upon its seat. When the parts A B are so made, the hole or mouth d' will be covered when the part A is screwed down iirmly upon its seat or upper part of the cap B. Such hole, however, may be uncovered by simply unscrewing the part A sufficiently to bring the two holes d f in conjunction, or,in other words, so that the hole f may be directly over the hole d, in which case the inkstand will be open ready for introduction of a pen.

The simplicity and eiciency of an inkstand made as described cannot fail to be apparent to most persons.

I do not claim the inkstand as described in the United States Patent No. 30,266 and granted October 2, 1860; nor do I claim an inkstandecap made simply as an unperforated cover to screw upon the mouth of an inkstand; nor do I claim a simple perforated rotary slide to rotate on a perforated cap or plate and either above or below the same when such plate is used to cap an inkstand and is perforated with a hole having an eccentricity corresponding with that of its fellow plate or perforated cap. My invention involves another element-viz., the screws above named and their peculiar arrangement relatively to that of the two holes of the two caps or plates, for it is by the said arrangement of such holes and the employment of the screws that the upper plate or cap While being rotated will be forced downward upon the other in such manner as to close its hole and so as to be liquid or ink tight.

Vhat I claim as my invention is- My improved inkstand as made with its cap-screws and holes arranged in the parts A B, substantially in manner and to operate as specified.

AUGUSTUS P. GRIFFING.
