Car-Axle Boxes.
No 156 070. Patented 0ct.2o,174.
UNITED STATES PATENT OFFICE.
JOSIAH O. TUOK, OF OAKLAND, CALIFORNIA.
IMPROVEMENT IN CAR-AXLE BOXES.
Specification forming part of Letters Patent No. 156,070, dated October 20, 1874; application l'led August 26, 1874.
To all whom 'it may concern:
Be it known that I, J oslAn C. TUcK, of Oakland, in the county of Alameda and State of California, have invented an Improved Oiler for Oar or other Axles, of which the following is a specification:
This improved oiler is more especially designed for car-axles, but itis applicable to oilin g other axles, as will be obvious from the description thereof. This improved oiler consists, in substance, of a cam edge, which is attached to and revolves with the axle; a piston or plunger, which is arranged to travel Within a suitable chamber or cylinder, and is connected with said cam, so that therevolution thereof will move the piston forward and backward within its chamber; and a tube connecting the plunger-cylinder with an oil-reservoir below the axle-box. The plungencylinder opens to the bearing to be oiled, and the oil-connecting tube has a check-valve arranged for the oil to pass to the plunger-cylinder, and to hold it from flowing back to the oil-reservoir through the said oil-connecting tube, al1 as hereinafter fully described.
In the accompanying plate of drawings my improved oiler is illustrated.
Figure l :is a central vertical section of a railroad-axle box, with my improved oiler in partial elevation and section; Fig. 2, a plan view; and Fig. 3, a cross-section in plane of line a: at, Fig. 2.
In the drawings my im proved oiler is shown in connection with a car-axle, and A is the axle, B the shell or case, into which the axle passes, and O the block or plate making the bearing at the upper side of the axle, all as ordinarily in car-axle boxes and oilers. a, a
cam edge, attached to outer end D of car-axle, and revolving with the axle; b, a grooved co1- lar, which receives the edge a. This collar is attached to a plunger or piston-rod, c, which is arranged within a chamber or cylinder, d, formed in and along the bearing block O, which rests on the car-axle. This plungerchamber d, at its inner end f, connects by the branch passage g in the block with the bearing-face of the block 011 the car-axle, and by a tube, h, is connected with the chamber E of the shell or case B, which is below the caraxle, this chamber E being the receptacle for the oil. In the tube h, and near its junction with the plunger-cylinder d, is a check-valve, k, located, to allow the flow of oil to the plungercylinder d, and to prevent its flow back through the tube h to the oil-reservoir E.
The revolution ofthe axle-cam a moves the plunger c forward and backward in its chamber d, and thus pumps up the oil from the oil-reservoir E into the chanlberd, froln which it l'lows to the bearing-surface between the block O and the car-axle A, securing thereby the oiling ofthe same.
Obviously by changing the cam a for a cam of a greater or less throw, the supply of oil to the bearin g will be correspondingly increased or decreased; and, furthermore, the greater the speed of revolution of the axle, the more the oil will be fed to the bearing therefor.
What I claim as my invention is The combination of the cam a of axle A, oil-reservoir E, plunger c, chamber d of bearing-block O, tube h, and checkyalve K, all to operate substantially as and for the purpose specified.'
