The invention relates to the lubrication of railway axle journal and bearing by the pumping of lubricant from the bottom of a journal box, mounted on the bearing, up to the journal. The invention comprises a simple, economical, and effective device which may be inserted through the usual opening in an American Association of Railroads type journal box and beneath the journal and be retained at the intended position in the box for normal operation.

The main object of the invention is to provide an adequate pump accurately positioned lengthwise of the journal and b x and applicable to and removable from the assembled journal and box without jacking up the box and removing the journal bearing or wedge or both, in order to place the lubricator in position.

In some respects the invention comprises an improvement upon the structure disclosed in co-pending application, filed by the present inventor October 9, 1950, Serial No. 189,232.

In the accompanying drawings illustrating seleoted embodiments of the invention:

Figure 1 is a vertical longitudinal section through an ordinary A. A. R. journal box mounted upon a standard journal with the usual bearing and wedge and with the lubricator in functioning position. The section is taken approximately on the line i--l of Figure 2.

Figure 2 is a front view of the lubricator structure showing the same assembled with the box, a portion of the front of the box being broken away to more clearly illustrate the structure.

Figure 3 corresponds generally to the lower portion of Figure 1, but illustrates. another form of the invention.

Figure 4 is a vertical section taken approximately on the line 4-4 of Figure 3 with some of the parts eliminated to better illustrate other features.

Figure 5 is a top view of the pump, pump actuator, and pump positioning structure shown in Figures 3 and 4.

Figures 6 and 8 correspond to Figure 3, but show respectively different forms of the invention.

Figures '7 and 9 correspond to Figure 2 but illustrate the structures shown in Figures 6 and 8, respectively.

In Figures 1 and 2, the journal I, bearing 2, wedge 3, and box 4 are of the usual A. A. R. construction. Mounted in the lower portion of the box is a pump 5, lubricant distributor 6, a pump actuating device I and a positioning 11 Claims. (Cl. 308-434) 2 structure, comprising a U-shaped locating rod 8, a distributor support arm 3, a frame member l0, and a yielding thrust yoke I I.

The left hand end of locating rod 3 and the intermediate portion of support arm 5; are coiled about a fulcrum pin [2 seated through washers i2a on the box bottom wall It which curves upwardly and forwardly to form the front wall of the box. The left hand end of support arm 9 is pivotally connected at H! to frame member m. The lower end of thrust yoke H is slidably and pivotally connected at A to the upper end of frame Ill and the upper end of yoke I I bears against downwardly facing lugs E5 on the box top wall. Coil springs i5 exert a thrust on frame member Iii which moves the latter downwardly and moves arm a and locating rod 8 inwardly to the extent permitted by the engagement of the right hand end of locating rod 8 with the box rear wall H, or with an oil and dust guard l8 seated against wall IT, or by the engagement of distributor 6 with the journal.

Pivotally supported on fulcrum [2' is a carrier I9 and a pump actuating lever 29. The right hand end of carrier 19 mounts pump 5 and the upper end of lever 20 mounts contacts 2|, adapted to engage the end of journal I. Springs 22 between carrier is and lever 28 normally hold these parts in the relative position shown but act as a safety relief in the event of excessive journal movement, clogging of pump by ice, or other condition, which would tend to break the lever. The pump body comprises a collapsible chamber receiving a spring 23, substantially weaker than springs 22, which is compressed when the journal moves to the left and expands as the journal moves to the right. The pump body has an inlet valve 24 at its lower end and a discharge valve 25 at. its upper end leading into distributor 6.

When the box and journal move relatively to each other as the axle plays back and forth during the travel of the vehicle, lever 20 is oscillated and carrier I9 is actuated to alternately thrust the lower end of the pump body upwardly, collapsing the pump chamber and forcing lubricant within the body to the distributor, and downwardly, under thrust of spring 23, to draw lubricant through valve 24 into the pump body. A screen 26 guards the intake valve and limits the downward movement of the pump body and carrier [9.

Preferably, locating rod 8 and arm 9 are of spring wire, possessing sufficient resiliency to mount the parts in the position shown during assembly and normal operation, but capable of being flexed during insertion and removal of the lubricator into and out of the box through the space between the journal and the box bottom and front walls.

When the lubricator is so inserted, the pump and pump lever fulcrum are positioned longitudinally of the box in accordance with the length of locating rod 8. Variation in the space between the journal and the bottom of the box, due to manufacturing tolerances, and wear of bearing 2 will not affect the relation between fulcrum l2 and the end of the journal. Support arm 9 will tilt on fulcrum l2 to elevate distributor 6 into contact with the journal independently of the position of furcrum l2 longitudinally of the box. Yoke H and spring IE will thrust frame member ID downwardly to hold distributor 6 against the journal and washer |2a against the box bottom wall. Variation in the distance between the journal and the bottom of the box will be accommodated by the flexibility of support arm 9 and the distortion of spring I6.

Figures 3, 4, and illustrate a structure in which each side of the locating rod 30 and distributor support arm 3| is formed preferably from a single length of spring wire, the outer right hand end of each wire being turned inwardly at 32 to engage the box rear wall 33, the extreme end of arms 3| being coiled around a pin 3% carried in a bracket 35 which mounts the distributor pad 36. However, all of the elements 30, 3| may be formed of a single length of wire or they may be formed separately and welded together if additional stifiness is desired. By withdrawing a retainer 31, which holds a pin 34, arm 3| and bracket 35 assembled, the distributor and the bearing of the lubricator may be readily disassembled for replacement of the distributor. Each element 30 and 3| forms a spring unit seated against the box bottom wall, and against the journal independently of the thrust by yoke 38 and frame 39 which function merely to move the elements 30, 3| and the parts positioned thereby inwardly of the box to the position shown. Pump 40, carrier 4|, operating lever 42 and associated parts are supported from the box lever 42 and associated parts are supported from the box bottom wall by mounting elements 43 and fulcrum pin 44.

Except as indicated, the structure and operation of the lubricator are as previously described in respect to the structure shown in Figures 1 and 2.

In the structure shown in Figures 6 and '7, the locating rod 59, frame member 5|, and thrust yoke 52 are similar to the corresponding parts shown in Figures 1 and 2, but the support arm 53 for the distributor 54 is a rigid member pivoted by the pump fulcrum pin 55 to an anchor 56 pivotally connected at 51 to frame member 5|. A torsion spring 58, seated on elements 5| and 53, thrust the right hand end of the support arm 53 upwardly to the extent permitted by the contact of the distributor with the journal.

In the structures shown in Figures 8 and 9, the

locating rod 60 corresponds to that shown in Figures 1, 2, and 6, 7 but the support arm 6| for distributor 62 extends to the left a substantial distance beyond the operating lever fulcrum 63 and is enlarged at 64 below fulcrum 63 to bear on the box bottom wall under the downward thrust of spring yoke 65 on frame member 66 which is similarly enlarged at 6! to bear against the box front wall, elements SI and 66 being pivoted to each other at 68. The lengthening of arm BI and the shortening of frame member 66 avoid a tendency present in some assemblies for the lower end of the spring thrust frame member to swing away from the box bottom wall towards the journal to such an extent as to interfere with the thrust of the distributor against the journal by the distributor support arm.

Each form of the invention attains the general objects set forth in the introductory portion of the specification forming a simple lubricator in which all of the parts are positioned properly without adjustments and without any parts being welded or otherwise secured to the journal box.

This feature together with the use of the spring wire elements adapt the device to be readily inserted in ordinary journal and box assemblies and readily removed and replaced as may be desired.

The details of the construction may be varied other than as shown without departing from the spirit of the invention and the exclusive use of those modifications coming within the scope of the claims is contemplated.
