To all whom it may concern:

Be it known that I, HARRY" CHARLES GAMAGE, a citizen of the UnitedStates, residing at the city of New York, in the county of New York and State of New York, have invented a certain'new and useful Improvement in Lubricating Devices for Shafts, &c., of which the following is a specification.

' The invention relates tollubricating devices for rotary shafts, and has for its object to simplify construction and insure more perfect lubrication.

The device is herein illustrated in an embodiment more especially designed for the lubrication of car axles,'in which the lubricant contained in a suitable vessel, such as the axle box, is intermittently transferred from said box to an exposed side of the journal, by means of a vibrating arm, prefer-' ably provided with a plate at its end, which raises or throws said lubricant to said journal surface. It is not essential that the arm or i plate'shall actually touch said surface, since its path of vibration may terminate at a distance therefrom over which interval the lubricant may be project'edand this result is assisted by making the arm a spring or actu ating it by resilient mechanism, or as herein shown, by adopting both expedients, The construction is also such that although the arm is operated by the'rotation of the'shaft, longitudinal play of the shaft in its bearing .is permitted and transmission thereof to said arm prevented. y

In the accompanying drawingsFigure 1 is a section of a car axle box showing my device in position, taken on the line '1, l, of Fig. 2. Fig. 2 is a section on the line 2, 2, of Fig. 1. Figs. 3 and 4 show thegear box in detail, Fig. 3 being a section on the line 3, 3, of Fig. 4, and Fig. 4 beinga section on the line 4, 4, of Fig. 3. 4

Similar letters "of reference indicate like parts. I

The car axle box A, axle B and bearing 0, are all of the usual pattern. Resting on the bottom of the box is a metalframe having side members D and transverse member E, the side members being curved near their ends to suit the inner curvature of the front of the box and the transverse member E resting against the rear wall of said box. Pivoted to each side member are two bars F, G,

which meet at their upper ends and are connected' by pins H. A light frame fitting 1 within the'box is thus provided, on the side members D of which, near their front ends, is supported a rod I on which is a long sleeve J, from which extend rearwardly two parallel plates K. A leaf spring arm L is secured at its end between said plates. Said spring arm extends beneath the axle journal,

and near its rear extremity has an opening through which passes a lug on the bottom of a metal plate M, saidlug being secured in the opening by a transverse pin on the under side of the plate. Any other convenient means of attaching the plate M to the spring arm L may be used. When the plate is in the position shown in Figs. 1 and 2, it is submerged in oil contained in the axle box.

In the end of the axle A is tapped a threaded hole to receive a threaded hollow rod N, provided with a flared flange O, which is received in a correspondingly formed countersink in the axle. Said rod carries a worm P and is received in bearings formed in both sections of a two part box Q, the sections of said box being flanged and connected by boltsand nuts as shown in Fig. 4. J ournaled in said box is a shaft R carrying'a pinion S engaging with worm P 'X, which loosely enter openings in the upwardly projectingarms of a frame Y, the horizontal connecting member of which passes beneath'spring 'arm L and is secured in place by rivets which also serve to fasten said armbetween' the plates K.

The operation ofthe device is as follows:

Motion is communicated from the rotating axle A to the worm P and so to pinion S and crank disks T; From said disks through the frame U, spring V and block W, the spring leaf arm L is swung intermittently upward, as indicated by the arrows in Fig. 1. The plate M, is thus caused to dash oil upward and against the under side of the axle journal, thus providing an ample sup ply of lubricant to the bearing. The faster the axle rotates, the more numerous the swings of the plate M per given time, and hence the greater the quantity of lubricant delivered. The interposition of the elliptical springbetween the crank disk-(T and Especial attention is called to the jointformed between the arm L and frame V by the loosely fitting pins X entering frame Y. This permits longitudinal play of the axle B in its bearing without transmitting said movement to said arm.

I claim:

1. In a shaft lubricator and in combination with the shaft journal, a vessel for holding lubricant, and, in said vessel, a vibrating arm for intermlttently throwing said lubricant from said vessel to said shaft journal.

2. The combinationof a-rotary shafthaving longitudinal play in its bearing, a device for applying lubricant to said shaft, and mechanism for transmitting motion from said shaft to actuate saiddevice; the said transmitting mechanism being operated by the rotation of said shaft and constructed to permit longitudinal play of said shaft in both directions and in all positions of said device without transmitting said movement to said device.
