IMPROVEMENT IN CAR-AXLE LUBRICATORS.

Specification forming part of Lettere Patent No. 187,553, dated February 20, 1877 application filed October 18, 1876.

To all whom it may concern:

Be it known that I, WILLIAM PALMER, of the city and State of New York, have invent ed an Improvement in Lubricators for Gan. Axles, of which the following is a specication:

Gar-axles have been made with a bearingbox, within an oil-receptacle, and the lubricating material has been supplied by a roller kept in contact with the under side of the axle by springs.

My invention is made for suspending the oilsupplying roller in such a manner that it is free to move laterally by any change oi' position oi' the box relatively to the axle, thereby preventing the injury oi' the oil-supplying roller, and, at the same time, insuring constant contact ot' the roller and axle; and for this purpose I employ a rectangular frame, in which is journaled the roller, said frame being suspended atits corners by spiral springs to keep the roller in contact with the axle, and also allow ofthe lateral motion. Y

In the drawing, Figure l is a vertical section ot' the axle and box, and Fig. 2 is a plan of the oil-supplying roller and its supports.

The axle or shaft a is of any character to which the improvement is applicable. The box b is made with any ordinary cover or door, giving access to the interior, as usual, and there is a bearing or journalbox, c, for the Weight to rest upon the axle or shaft. Within the box b there is a movable plate,d, with the oil-receptacle c near the middle thereof. rIhis is to be oi' a size adapted to the quantity of lubricating material required.

Near the angles ot' the plate d are tapering columns l, to the upper ends of which suspensionsprings f are attached. The other ends of these springs are fastened to the angles oi' the frame g, that receives within it the oilsupplying roller h, ot' wood, metal, o r othersuitable material, and said roller h passes down into the receptacle e, and hence receives upon its `surface the lubricating material. The springs f draw the frame g upwardly sufficiently to keep the roller h in contact with the under side of the axle a, and hence the roller is constantly revolved and the oil snpplied to the axle whenever the car is in motion.

There is almost always considerable end movement ot' the axle in the box or oi' the box upon the axle. In either instance the frame g and roller h remain in their proper position to the axle in consequence ot' the springs f yielding; and hence there is no unnecessary wear upon the roller or risk oi' the same loecoming displaced.

Blocking-strips n may be introduced between the tapering columns l and the inside ofthe box a, to hold the plate d, and parts connected therewith, in position.-

I am aware that it is not new to suspend the oiling-roller by spiral springs, and therefore do not Wish to be understood as'broadly claiming this feature; but

l. The frame g and roller h, in combination with the suspending-sprin'gs f attached to the angles ofthe frame g, and the columns l receiving the other ends ot' the springs f, s'ubstantially as and for the purposes set forth.

2. The combination, in an axle-box, oi' the receptacle c, the frame g, roller h, suspensionsprings f, and removable plate d, substantially as set forth.

Signed by me this 16th day of October, A. D. 1876.

Y WM. PALMER.
