FREDERICK W. HODGES, OF DETROIT, MICHIGAN, ASSIGNOR TO DETROIT LUBRICATOR COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

DEVICE FOR LUBRICATING CAR OR LOCOMOTIVE To all whom it may concern:

Be it known that I, FREDERICK W. Honors, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Devices for Lubricating Car or Locomotive Wheels, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to a device for feed ing oil upon the flange of a car or locomotive, the same being'rnormally inoperative but adapted to feed by and upon the vibrations which arise when the vehicle is in central section through the oil supply tank,

and with the pump therein, of the preferred form of my device; also showing in section the discharge nipples at the wheels; Fig. 2 is a section online a:m of Fig. 1; Fig. 3 is a side elevation looking from the righthand of Fig. 2; and Fig. 4 is an enlarged section through one of the discharge nipples.

At the present time it is well understood that to apply lubricant to the flanges of locomotive driving wheels very materially lengthens the service or life of the driving I surfaces thereon, and a number of devices have been used to effect this lubrication. Condensation displacement. o l feedmg devices having a discharge pipeleading to the wheel, with steam blowing through the pipe to spray the oil upon the flange, have een employed; spring-pressed graphite sticks have also been applied to the wheel; and it has also been roposed to have an oiltank with gravity f ed, the outlet therefrom being controlled by a valve, said valve to be operated by a rolling ball,"the ballbemg set in motion by the vibration or oscillation of the locomotive.

Any device which feeds the 011 constantly Specification of Letters Patent.

is objectionable'because it willfeed the oil while the locomotive is standing still and any surplus of oil upon the wheels will be transmitted to the track and very greatly reduce, 11? not entirely eliminate, the tract1on, The rolling ball construction for operatmg the valve lacks sensitiveness and depends upon gravity for eeding,and the dust and dirt will accumulate in running and will fill up the discharge orifices and may render the device inoperative. In the devices in which an unobstructed feed pipe is used, from the oiltank -or feeding deviceto the wheels, when the locomotive stops the oil continues to drip until the pipe is empty, and thus feeds the oil unnecessarily and reduces the traction when it is most needed.

7 My devicev overcomes the objections to these prior devices, is extremely sensitive in operation and eflicient in the delivery of 011 when most needed and stops feeding whenever the train comes to rest.

A represents an Oll tank in which I have ders have an intake-nipple, a, controlled by a check-valve, b, and a discharge port, ('2, controlled in this instance by a spring-pressed check-valve, 0?. At the lower end I have shown these cylinders each as resting upon These cylin the bottom of the tankand held in position therein by a flanged nipple, C, passing through the tank and clamping the parts tightly together. In each of the cylinders B with sleeves, H, having laterally projecting rock-arms, I, I, at opposite sides, which pass through the slots in the pistons D D". The sleevesv H may be detachably secured to the rock-shaft as by set-screws, J. The rockshaft G preferably extends through the wall of the oil tank and is provided with a pendulum, 0, having a weight, P, preferably adjustably secured thereon, as by the set-screw Q. Discharge pipes, K, K, communicate with the discharge passages through the nipples, C, leading to a point in proximity to the wheels, L, to be lubricated. At the ends of the pipes, K K, are check-valves, M, M. In this case I have shown secured to the ends of the pipes K K discharge nipples, R, connected with the ends of the pipes by means of a ball-and-socket joint, as shown at S, and having within an adjustable drip pin, T,leading into close proximity to the-flange of the wheel where the oil isto be deposited, the pin T being of smaller diameter than the nipples, R, so that the oil may freely pass out and flow down the pin and drip upon the wheel at the desired point. vThis construction of discharge nipple forms no part of my .present invention, and any other means may be employed for bringing the oil upon the Wheel at the desired point, or the pipes K K may terminate in close proximity to these wheel flanges.

It is obvious from the description of the mechanism that as the locomotive travels over the track there is more or less oscillation or vibration imparted to it, and such oscillation or vibration will cause the Weighted pendulum, P, to swing and the swinging thereof will rock the shaft G and rock arms I I thereon and raise and lower the pistons D D, in the cylinders B B and draw oil in through the inlet opening and discharge it through the discharge port into the pipes K K; and when those pipes have been filled the further movement of the pump will unseat the valves M M and cause the oil to drop or flow upon the wheel flanges.

With the construction shown, in which there are four pumps, the oil will be fed to the four drivers, two upon each side, or to any other wheels desired. It is also obvious that when the locomotive is at rest there will be no motion imparted to the pendulum and no oil will be fed. By having the checkvalves, or other arresting means, immediately adjacentv the point to which the oil is to be delivered, as soon as the device stops forcing the oil the supply to the wheels will be stopped and only the oil below the checkvalve will drip upon the wheels,--which will be an'entirely negligible quantity.

The pendulum device for controlling the oil feed is exceedingly sensitive-and by adj'usting the screws F vertically and also by adjusting the weight P on the pendulum 0,

it may be adjusted toany desired feed.

By having the forced feed for feeding the oil the danger of stoppage by clogging at the discharge end of the delivery pipes is practically'entirely eliminated. I

While the construction herein shown is the construction which I prefer to employ, it is obvious that it may be' varied inmany ways'without departing fromthe spirit ofmy invention.

While I have shown the device as delivering oil to lubricate the wheel flanges, it is obvious that the point of delivery is immaterial so far as my invention is concerned, and that it can be used for-delivering oil at other-points of the vehicle What I claim as my invention is:
