This invention appertains to a wheel iiange lubricator for railroad rolling stock of the type shown in the Ross et al. application for patent, Serial Number 39,414, led July 19, 1948, now matured into Patent No. 2,550,865 on May 1, 1951.

One of the primary objects of the present invention is the provision of a novel driving connection between the pumps carried by the reservoir body and the driving arm welded to the journal box, so that the driving connection can be accurately set and'adjusted relative to the position of the reservoir body on the truck, and the position of the driving arm on the journal box, to effectively take care of Variations in journal box and truck frame conditions, whereby to bring about the desired smooth operation of the pumps by the sprung and unsprung parts of the truck during the travel of a locomotive or other piece of railroad rolling stock.

Another salient object of the invention is to provide novel means for independently adjusting the working stroke of each pump piston, so that each pump in the reservoir body can be set to deliver the exact desired quantity of oil needed for the particular wheel being served by the pump.

A further important object of the invention is the provision of means for simplifying the arrangement of the pumps in the reservoir and the mounting thereof in the reservoir, so that the pumps can be easily repaired or cleaned when necessary.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specically described and claimed, and illustrated in the accompanying drawings, in which drawings,

Figure 1 is a side elevational View of a railroad locomotive or car, illustrating one truck thereof and showing the improved ange lubricator operatively connected therewith.

Figure 2 is an enlarged detail vertical sectional view through the oil reservoir and one pump, the section being taken substantially on the line 2-2 of Figure 3, looking in the direction of the arrows.

Figure 3 is a fragmentary top plan view illustrating the mounting of the reservoir and the driving arm on the truck, parts of the view being shown in section.

Figure 4 is a -transverse sectional View through the reservoir taken on the line -ll of Figure 2, looking in the direction of the arrows.

Figure 5 is a fragmentary detail side elevational view of the upper end of the reservoir illustrating the adjusting arm for one of the pumps.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter L indicates generally, the improved lubricator for use with the truck IB of a piece of railroad rolling stock, such a as locomotive I I.

The truck I 0 is of the type found in general railroad use and hence will not be described in detail, but the same includes the sprung frame I2 carrying pedestals I3, in which are slidably mounted for vertical movement journal boxes I4 carrying the axles for the car wheels I5. The journal boxes I4 are carried by an unsprung part I6 of the truck.

The lubricator or oiler for the flanges of the car wheels l5, is automatically operated by the movement between the sprung and unsprung parts of the truck I l), during movement of the locomotive or car and the lubricator or oiler L is so yconstructed that the oil is forced up to the flange of the wheel instead of down by gravity. Hence, oil is only supplied to the flanges of the car wheels while the car is in motion.

The improved lubricator or oiler L, includes a reservoir body Il, the upper end of which is closed by a removable cover I8, rigidly held in place by machine bolts I9. A gasket 20 can be interposed between the body Il and the cover I3, to prevent loss of oil in the reservoir, and to prevent the entrance of dirt and water into the lubricator from the outside. The reservoir body Il is provided at one lower corner with a transversely extending boss 2l formed with an opening 22 for a bearing bushing 23. The bushing receives a mounting bolt 24. One end of the bolt is enlarged in diameter, as at 25, and this end is welded, as at 26, to the sprung part I2 of the truck It, adjacent to one of the journal boxes I4. The outer end of the bolt has threaded therein a suitable lock nut 2l, so as to retain the reservoir body on the bolt against displacement. Obviously, washers of the desired type can be placed between the reservoir body Il, and the sleeve 25, and the nut 2l' and the reservoir body. The bottom wall 28 of the reservoir body can incline downwardly toward one end to provide an oil sump, and a removable drain plug 29 can be provided for the sump. Disposed within the reservoir body Il and carried by the cover I8 are a pair of like pumps 3U and 3|. One pump is utilized for supplying oil to lubricate one car wheel and the other pump is utilized to supply oil to another wheel. Under certain conditions, more oil may be required by one wheel than the other, and consequently, novel the sprung part cylinder block The bore 3A ycommunicates With the lower end of the` cylinder 33.v `Reciprocallyr mountedr within y .n the cylinder 33 is a pump plunger or piston 55,r

formed on a plunger' rod.: The pump plunger orpiston 35 rcan be provided with a sealing ring, if suchy should be desired. A 'supporting `rod' 3T f is securedto the: cover' i8., anddepends. therefrom,

and is-disposed between the cylinder blocks 52 ofthe pumps 3B and 3i. The supporting rod-is f rigidly'connectedgto the .cylinder blocks 32 by a suitable' bolt 33'.' Consequently; ,when theeoiver.

i8 is removed, thepumps are carried fromlthe reservoir body therewith.

In orderk to bring about oscillation. 'of theistub shafts 39, I provide an operating lever yoke de.

This yoke le includes spaced parallel arms er, which straddle the reservoir and a connecting bridge piece disposed at one end of the reservoir. The arms l5 carry split clamping rings il which receive the outer ends of the stub shafts 39. Bolts 5B are provided for tightening the split clamping rings il into gripping contact With the stub shafts 39. When the stub shafts are independently turned for adjustment the bolts ll are loosened.

The lever yoke has formed thereon a socket de for detachably receiving a swivel ball formed on the end of a stud bolt 5|. The stud bolt in turn is rmly clamped to the lever arm 52. The lever arm 52 can be provided `with a series of openings for receiving the stud bolt 5l and the bolt can be placed in any selected opening. The end of the arm 52 from the stud bolt 5i is provided with a vertical eye 53 which receives a bearing pin 54 carried by the attaching arm or plate 55. The attaching arm or plate 55, is welded, as at 5B, or otherwise rigidly secured to the journal box I4 which is adjacent to the reservoir body I1. To retain the swivel ball '55 in position, clamping plates 5l are rigidly secured to the opposite sides of the socket 5U and resilient rings 58 can be interposed between the clamping plates 5l and the ball 50. The use of the ball 50 forms an important feature of the invention.

In applying the lubricator to the truck l0 of'o. car, the attaching-sleeve 25 is Welded in place on l2 of the car truck lil, adjacent to a desired journal box, after which the arm or plate 55 is Welded to thejournal box. The active length of the lever armA 52 is had by placingl the and this in'turn,

The cover itk can beprovided with a suitabley filler cap 55, anda screen G- can also be carried by the cover le inward rof the cap.l l

` Much stressis laid on the arrangement of the operating.yokel ed, and; its connection with the attaching armorplate55yas' desiredadjustments r can be readily made during the installation of the lubricator on the car truck. Likewise, the arrangement of the pumps and the operating stub shafts 35 therefor is also important.

The universal ball connection with the yoke 44 and the vertically disposed pivotal connection between the attaching arm 55 and the operating lever 52, allows movement in the connection between the yoke and the journal box to compensate for any shifting of the sprung and unsprung parts during travel of the locomotive. Thus, all strains are eliminated. It is to be noted, however, that the stud bolt 5i 'and the ball 55 are bodily lifted up and down during the raising and lowering of the journal box, which bringsv about the rocking of the yoke 44. The reservoir il is freeto roek on its bolt 24 to compensate for the arc of movement of the lever 52 and the yoke ell.

Changes in details may be made without departing from the spirit. or the scope of this invention, but What is claimed as new is:

l. In a flange oiler for car Wheels, an oil reservoir, means rockably connecting the oil reservoir to a sprung part of a car truck, a pump in said reservoir including a cylinder and a pump plunger reciprocally mounted in the cylinder, an operating lever carried by the reservoir and operatively connected to the pump plunger, an attaching plate rigidly secured to an unsprung part of the car truck having a vertically disposed pivot, an operating arm movable on said pivot, a ball head carried by the operating arm for movement therewith, and a socket for said ball'head carried by the lever` 2. A flange oiler for car Wheels as set forth in The' borel 34 has 5 claim 1, and means for adjusting the ball head longitudinally of the operating arm.

3. In a flange oiler for car wheels, an oil reser Voir, means rockably connecting the oil reservoir to a sprung part of a car truck, a pump in said reservoir including a cylinder and a pump plunger reciprocally mounted in the cylinder, a lever rockably mounted on the reservoir and operatively connected to the pump plunger, an attaching plate rigidly secured to an unsprung part of the car truck having a vertical pivot, an operating arm movable on the pivot, a stud rigidly carried by the operating arm, and a universal joint connection between the stud and the lever.
