JAMES H. MINER, OF LUMBERTON, MISSISSIPPI.

- WHEEL-FLANGE LUBRICATOR.

Be it known that I, JAMES H. MINER, citizen of the United States, residing at Lumberton, Mississippi, have invented certain. new and useful Improvements in Wheel-Flange Lubricators, of which the following is a specification.

The present invention relates to wheel flange lubricators and more particularly pertains to a device byrwhich liquid oil is automatically fed onto thewheel flanges.

The principal object of the invention is to provide a lubricating device adapted to be used on a wheeltruck in which liquid oil, preferably under pressure, is fed from a supply tank to a nozzle, from which it is sprayed directly onto the wheel flange; a spring seat valve being suitably placed so as to control the flow of oil, this valve being provided with controlling means adapted to be automatically operated by the swinging movement of the locomotive in rounding curves.

With this and other objects in view, the invention includes the novel features of construction and arrangement and combination of parts hereinafter described and particularly defined by the appended claims.

In the drawing Figure-1 illustrates one embodiment of the invention shown in elevation in the position assumed when the truck is on a straight track; Fig. 2 is a similar view showing the position assumed upon a curve.

Referring to the drawing, a valve casing 1 is attached at one side of the locomotive or truck frame. Communicating with a suitable oil supply source are a pair of pipes (not shown) through which the oil is conducted under'pressure to the inlet ports 2 V of the valve casing. Similar pipes 3 conduct the oil from the outlet side of the valve casing to nozzles 4, so positioned as to direct a jet or spray of the oil onto the wheel flanges pair of bell crank levers 6 are pivotally supported on the locomotive or truck frame and have their arms adapted to contact with the upper ends of the valve stems 5. The other arms 6 extend vertically upward and are allowed a limited amount of movement I Specification of Letters Patent. Application filed July 25, 1913.

laterally of the truck by stops 7, and the upper ends of these arms are preferably provided with weights. The arms (5 are extended inward toward each other beyond the points where they are adapted to engage the valve stems 5, and their extremities a are far enough apart to normally allow the operating weight 8 to pass between them. By normally I mean when the engine or car is running upon a straight track. The weight 8 is mounted to slide vertically upon a guide rod 9 and is yieldingly supported by a spring 10, the action of which may be adjusted by the movable collar 11' secured to the guide rod by thumb screw 12.

It will be understood that under the jar or vibration of the train when in motion the weight will be constantly moving up and down, but when on a straight track the weighted arms of the levers will lie in a vertical position, and hence the weight 8 will move between the ends a and no oil will be fed. WVhen, however, a curve is encountered, the inclination of the track will cause one or the other of the bell crank levers to be rocked so as to swing its end a downward in position to be struck by the weight 8, which latter, by its vertical movement referred to, causes the valve to be opened and a jet of oil to be delivered to the wheel flange. It will be readily apparent that this opening action will be intermittent, due to the vertical reciprocations of the weight, so that wasting of the oil which would ensue by the delivery of an unnecessary amount of oil if the valve were held constantly open is prevented.

Having thus described my invention what I claim is: I

1. A wheel flange lubricator comprising an oil feed, with a valve therein, avalve stem on said valve, a device adapted to be moved vertically by the jar or vibration due to the passage of the wheel on the track, and a rocking lever having a part for contact with the valve stem and a part adapted to be projected into the path of said vertically movable device, substantially as described.

2. A wheel flange lubricator comprising a passage for liquid oil, a valve in said passage, a valve stem on said valve, a pivotally supported bell crank lever having a vertical weighted arm and a transversely extending arm adapted to bear on the valve stem, a vertically moving spring supported weight, said bell crank lever having a part adapted to be projected in the path of said weight when rounding a curve.

3. A wheel flange lubricator comprising a pair of conduits, valves in said conduits having projecting valve stems, a pair of bell crank levers having vertically disposed weighted arms, and inwardly extending arms having portions adapted for engagement with said valve stems, and a vertically movable spring supported weight adapted normally to pass between said inwardly extending arms, one or the other of said arms being brought into the path of movement of said weight when rounding a curve.

4. A wheel flange lubricator comprising a pair of oil conduits, valves in said conduits, valve stems projecting outward from said valves, pivoted bell crank levers having sub stantially vertical arms carrying weights, means for limiting therocking movement of said weighted arms, said bell cranks having arms extending toward each other and adapted, on the inward movement of the weights, to contact with the valve stems, a guide rod located intermediate of said in wardly extending arms, a weight movable vertically on said guide rod, a spring supporting said weight, and means for adjusting said spring, said weight being normally clear of said inwardly extending arms but adapted to contact with one or the other of the same on rounding a curve, substantially as described.

In testimony whereof, I aflix my signature in presence of two witnesses. JAMES H. MINER.
