- i-MPROVEMENTIN CAR-AXLE LUBRICATORS- specification formingpart of Letters Patent No. 181,428, dated August 22, 1876; application To all whom it may concern:

Be it known that I, JAMES B. FL YNT, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Gar-Axle Lubricators, which improvement is fully set forth in the following specification, reference being bad to the accompanying drawing, in which Figure 1 represents a longitudinal vertical section. Fig.2 is a transverse vertical section on a larger scale that the previous figure. Similar letters indicate corresponding parts. This invention relates to certainimprovements in that class of car-axle lubricators in which an absorbent pad. is supported by springs, which keep said pad in contact with the journals of the car-wheel, the lubricating material being supplied to the journals by a wheel supported by springs connected with its journals and pad-supporting springs in such manner that said wheel will be within I the car-axle box, and be rotated by the rev-,

olntion of the car-axle or journal supplying it with lubricating material.

My invention consists in arranging an eccentric lubricating-wheel within, and support-- ing it on, a spiral spring, which spring also serves as a support for the absorbent pads,

and a frame for sustainin g the dirt-excluding jacket, the gudgeon or axle of the lubricatingwheel being connected to and suspended by rods or links, all as more fully hereinafter described. p

In the drawing, the letter A designates the pad of my lubricator, which consists of felt or other absorbentmaterial, and which is sup I ported by a spiral spring, B. With the pad which is, by preference, made of a coiled spring, the outer coil of which-forms a true circle, which, however, is not concentric with the center of the wheel. This wheel turns loosely on an axle, E, from the ends of which extend rods F (see Fig. 1) that are secured to the coils of the spiral spring B.

By these means a luhricator is obtained, all

the parts of which are yielding or elastic, so that the same can be readily compressed and introduced into a car-axle box of the ordinary construction, and after having been introduced the pad A is held in close contact with the journal of the axle and the elastic eccentric wheel D drips down into the lubricating material, while it also bears against the journal, so that the same, by the frictional con-' tact with the journal, will be caused to revolve and to supply the journal with lubrifinger, G, which, after the lubricator has been adjusted in the axle-box is turned out, andcaused to bear against the front wall of the box, so as to prevent the lubricator from sliding out of its correct position.

By this construction the numerous springs heretofore employed for supporting the jacket and lubricating-wheel are dispensedwith, a

single spring being made to support a dustexcludingjacket, an eccentric wheel, and absorbent pads.

What I claim by Letters Patent, is

The combination, in a car-axle box, of an absorbent pad supported upona vertical spiral spring, resting upon the bottom of the axlebox, and provided with a flexible jacket, said jacket and pad inclosing an eccentric wheel turning loosely upon an axle supported by rods jointed to its ends and to the coils of the spring, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 31st day of May, 1876.
