HENRY HAMMOND, OF HARTFORD, CONNECTICUT.

IMPROVEMENT IN PORTABLE LUBRICATORS.

Specilcation forming part of Letters Patent No. 99,082, dated January 25, 1870.

To all vwhom 'it may concern.-

Be it known that I, HENRY HAMMOND, of Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Oil-Cup; and I do hereby declare that .the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon` Figures 1 and 2 are top views of two different forms of the improved oilcup. Figs. 3 and 4 are verticalsections of the same through the middle of the cup.

Like letters in the several figures indicate like parts. l

My invention consists in furnishing the oilcup with a conical valve, A, which is operated by a screw, E, and regulated and controlled by an index, G, attached to the head, so that any desired quantity of Oil may be allowed to pass through the aperture B tO the machinery. The valve A is at the lower end of the stem C, which works through the cover Or top D of the oil-cup, with a screw, E.

Attached to the head F of the screw is an index, G, which serves to show theamount the valve A is opened. It also serves as a clamp` screw tO hold the head F iirmly in any desired position when set. The point of this index can be set at any point of the graduated arc 0 l 2 3, Src., Figs. l and 3, which numbers are intended to show the number of drops passed in a given time through the valve A.

H is the cap Of the feeding-hole7 which is removed to fill the Oil-cup. In Figs. l and 2 this aperture is shown in the top of the cup. In Figs. 3 and 4. a different arrangement is shown. The feedingtube a a passes through the stem C, and the cap H is placed upon the top of the head of the screw F. The cap H is furnished with an airhole, b, which admits the air to supply the place of the oil expended.

I is a screen, for the purpose of separating any impurities that may be in the oil and preventing their reaching the valve A.

The Operation of my invention is as follows:

Vhen the valve`A is closed, in the position;

shown in the drawings, the index G is at zero of the scale 0 l 2 3, Snc., and no oil will pass through the valve. If, now, the index be moved to 1, by turning the head of the screw E, the valve A will be slightly opened and one drop of `oil passed through in ten minutes, or some other given time. At 2, 3, &c., two and three times the same quantity passes through the valve, and so with the other graduations. By this means I am enabled to regulate the flow to any desired quantity.

That I claim as my invention, and desire to secure by Letters Patent, is-

In combination with an oil-cup, the cap or top D, screw-valve stem E, feeding-orifice a, cap H, having an air-hole, b, and set Or index screw G, working through the head F.

HENRY HAMMOND.
