CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 433,404, dated July 29, 1890.

Application filed May 15, 1890. Serial No.851,859. (No model.)

To all whom it may concern.-

Be it known that I, HENRY M. GOODMAN, a citizen of the United States, and a resident of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Car Axle Lubri cators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the IQ art to Whichit appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

1 5 Figure 1 of the drawings is a representation of this invention, and is a vertical section with end views of the brasses. Fig. 2 is a perspective view of the brasses. Fig. 3 is a detail.

This invention relates to certain improvements in car-axle lubricators, being equally adapted for street-car, locomotive, and steamcar axles; and it consists in the construction and combination will hereinafter appear.

In the drawings, A refers to the box, and B B designate the brasses arranged in said box, one below and one above the axle 0, each having a concave bottom surface, the upper one having in addition a central cavity a, communicating with a lubricant or oil passage to, extending through the top of said brass. The upper brass B rests and is held down upon the axle O by a wedge 12, inserted between said brass and the top of the box A,

3 5 and by means of the unoccupied space provided when said wedge is removed said brass can be readily removed when desired. The oil or lubricant cannot therefore escape when the axle is not in motion; but when the axle is in motion the oil will be readily taken up thereby. Thelower brass has at its sides supporting ledges or flanges b, which rest so as to have a little play in longitudinal grooves in the inner sides of the box A to provide for oscillations of the axle. To the outer end of this brass is yieldingly held an end plate (Z by means of set-screws c, passing through vertical slots 0' in said end plate and engaging screw-threaded apertures in said end of said brass to accommodate the vertical oscillations 0r movements of the axle, while in order to hold said brass up in contact at all times with the axle said end plate has a pendent stem or rod cl, preferably encircled by a spring (1', pressing upward against said end plate.

The drip or waste oil will be taken up by the lower brass and be thus fed to the axle and any surplus be passed off through the Waste-pipe (1 The lower end of the stem or rod (1 passes through the aperture in the horizontal arm of the bracket D to hold the spring in place, while the bracket itself, together with said end piece cl, is permitted also to yield or rock laterally to respond to a like motion of the 6 axle, said bracket having a cylindric arm or pivot d, bearing orsupported in an aperture in an arm or support 6, secured to the end of the box A. This arrangement permits the end plate (Z to accommodate itself to any movement of oscillation of the axle or box and yet retain its same position with relation to said axle. The end plate 61 heads up one end (the outer one) of the lower brass, thus converting the latter into a lubricant-reservoir. The lubricant or oil is fed from a common lubricant-reservoir (not shown) located at any suitable point on the car for the replenishing thereof through the pipe leading to a series of branch pipes f, one connecting to each of a series of supplemental lubricant reservoirs g. Each supplemental reservoir g is supported from or upon the truck of the car or engine and has a loose or sliding joint connection with a vertical pipe 7L, screwed or secured at its lower end to the box A. The upper sliding end connection of the pipe h is rendered oil-tight by the packing i, fitting around the same and within the lower part of a supplemental oil-reservoir g and held in place by the screw-cap j, screwed into the lower end of said reservoir and against said packing, said pipe passing through said cap. This arrangement provides for the independent vertical movement of said supplemental reservoirs with the like movement of the cars, said reservoirs sliding upon the lubricantp p Having described this invention, what I claim, and desire to secure by Letters Pat- I00 cut, is

1. In a car-axlelubricator, the combination,

with the axle-box containing an upper brass havingan oil-receiving chamber, of the central-supply oil-reservoir and a supplemental reservoir secured on said box, apipe connecting said reservoirs together, and a pipe having a sliding connection with said supplemental reservoir and secured to-the axle-box, substantially as set forth.

2. In a car-axle lubricator, the combination, with the lower brass, of the yielding end plate or piece having a pendent stem or rod engaging an aperture in a bracket 'pivotally supported in position, said stem or rod having a spring applied thereto, substantially as set forth.

3. In a car-axle lubricator, the combination,

with the axle-box, of the lower brass having ledges or flanges loosely engaging grooves or Ways in the inner sides of said box, the end piece or plate yieldingly connected to said brass at one end, and the bracket pivotally supported in position and having an aperture through which passes a stem or rod of said end piece surrounded by a spring bearing against said end plate and bracket, substantially as specified.

In testimony whereof I afiix any signature in presence of two witnesses.

HENRY M. GOODMAN. W'itnesses:

P. R. HENDERSON, GEO. O. STAUBER.
