IMPROVEMENT m LUBRICATORS.

Specification forming part of Letters Patent No. 176,422, dated April 25, 1876; application filed November 12, 1873.

To all whom it may concern:

Be it known that I, GEORGE B. BRYANT, of Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented 'a new I and Improved Lubricator; and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective view, and Fig. 2 is a vertical section.

Similar letters of reference in the accompanying drawings denote the same parts.

This invention is an improvement upon my car-wheel lubricator patented October 31,] 871, N 0. 120,489, and is designed to extend the application of the principles of construction there in shown to independent attachable and de-- tachable oil-cups for all kinds of machinery.

To this end, my present improvement consists it} the new article of manufacture herein shown, having the spring-follower, fibrous material, and oil-reservoir, combined with a small attachable and detachable cup, substantially as I will now proceed to describe.

In the drawings, G is the oil-cup, made of glass, metal, or other suitable material, having an oil-reservoir within it, a screw-stem, c; at its lower end, and a screw-cap, c, suitably packed, at its upper end. In the recess "at the lower nd of the oil-chamber is-a small quantity of cotton-waste, sponge, or other fibrous material, e, upon which a perforated plate, m, which may form a part of the spring, it preferred, is preserved by a spring, 8, which may be held in place by the screw-cap c, or by a small cross-bar or plate, a, which may be adjustable for the purpose of increasing or diminishing the pressure of the spring.

The oil flows from the chamber 0 to the journal through the sponge e and outlet t, its delivery being in inverse ratio to the pressure of the spring 8 upon the sponge.

This pressure is to be carefully adjusted, so that when the machinery is at rest, and the oilcup is not jarred, the steady pressure of the spring upon the sponge will prevent the oil from flowing out at all; but when the machinery is in motion, and the oil-cup subject to being jarred thereby, the vibration of the spring will allowsoine portion of the oil to work under the plate m into the sponge, and thence through the aperture t onto the journal.

The device is especially adapted for use in connection with common road-carriages, coalcars, locomotives, and other vehicles and machinery having sufficient vibration to operate the spring 8, as described.

Having thus set forth the nature of my invention, I claim- GEORGE E.- BRYANT.
