Another transverse rib 25 extends across the bottom and up the sides of the barrel portion, and a horizontal ledge 26 extends from rib 25 to the enlarged portion 7.

A screen S is supported by rib 25, ledge 26 and portion '7, and is spaced from the body and forms a partition of substantial area through which sufficient oil may pass by gravity to the inlet 17, but cotton waste and other impurities will be held away from the inlet. is used, the suction created by the pump piston 11, applied to a restricted passageway, tends to force lint and dirt through the screen to a greater degree than where a large screen as shown is utilized, resulting in stopping up the inlet.

An upstanding lug 2'7 near the forward end of the body is arranged to engage the lower portion of the journal when the box is jacked up, to prevent injury to the bell crank fulcrum, and a lug 28 immediately below lug 27 serves to transfer pressure from the lower wall of the box to the journal in a straight line.

A perforated plate 29 is bifurcated at its ends as indicated at 30 to receive the upstanding inner end of the body and the upstanding bell crank 12-43 at the outer end of the body. This plate serves to support a quantity of cotton waste W in contact with the journal whereby the lubricant supplied through cup 19 may be distributed by capillary attraction over the entire journal surface.

Plate 29 extends from side to side of the box and, preferably, lugs 31 are brazed to the inner wall of the journal box as shown to engage the ends of plate 29 and hold the same in position. An upstanding flange 32 on plate 29 is provided with a toothed upper edge 33 to engage the waste and prevent its working out past the end of the journal and interfering with the operation of the bell crank. Plate 29 positions the lubricator at the center of the box as illustrated.

Figure 5 illustrates how the lubricator and plate 29 may be inserted when the journal and the lower wall of the box are spaced apart by removal of the brass and wedge.

The downwardly inclined passage 19 insures the feeding of oil into the lower portion of the end chamber even though a new thick bearing is ap plied to the journal thereby tending to telescope members 9 and '7 to the maximum degree. This inclined passage is readily drilled through the top of chamber 8 before the closure 80. is applied thereto.

In the modification illustrated in Figure 6, the elevated lubricant chamber is eliminated and the oil is discharged direct from the pump cylinder 35 through a flap valve 36 into the lower portion of the discharge chamber 3'7 from whence it rises through the sleeve 33 into the discharge cup 39. The forward portion of the body and the remain ing features of the lubricator are substantially as previously described.

Figures 7, 8 and 9 show a modified form of bell crank whereby the device is arranged for use in connection with a type of journal box having the shoulder 40 throughout its middle portion. This is the type used on some railroads and this box would not accommodate the plain bell crank 12-13 shown in Figure 1.

In this form of the invention the pump plunger is operated by a crank arm 41 secured to a ful- If a relatively small screen cruzn pin 42 journaled in the cars 43 on the lubricator body and extending laterally beyond one of these ears as indicated at 44 to mount the lower end 45 of the outer bell crank arm which extends outwardly beyond the end of the pin and then forwardly and upwardly as indicated at 46 and then inwardly as indicated at 47 to engage the central portion of the journal. By shaping the outer arm of the bell crank as described, the same, when depressed, can pass around the side of the shoulder portion 40 of the box as indicated at 48 thereby permitting insertion of the lubricator and plate 49. A suitable lug 50 on the front end of the body of the lubricator is adapted to engage shoulder 40 on the box to hold the lubricator in position.

All forms of the invention are so constructed that they may be applied to standard A. R. A. journal box without any changes in the latter and without removing the box from the journal when the lubricator is to be applied or removed. The device is economical of manufacture and simple in operation. The mounting of the screen and the disposition of the supporting lugs eliminate difficulties which have been encountered heretofore in similar devices, and the various other novel features described contribute to the effectiveness of the device for its intended purpose.

Obviously modifications other than those illustrated and described may be made without departing from the spirit of the invention, and I contemplate the exclusive use of any variations which come within the spirit of my claims.

I claim:

1. In a railway journal lubricator, a body portion adapted to rest on the bottom of a journal box and including a pump cylinder, a piston therein, a lubricant receiving chamber above the level of said cylinder, a vertically disposed discharge chamber adjacent the end of said cylinder, a downwardly inclined passageway leading from said elevated chamber to the lower portion of said discharge chamber, a discharge sleeve telescopingly mounted in said discharge chamber, and a discharge cup carried by said sleeve.

2. In a railway journal lubricator, a body having a hollow interior forming a pump cylinder, there being an inlet port through the wall of said I body to said cylinder, 2. downwardly projecting lug on said body for supporting the latter above the bottom of a journal box, a downwardly extending rib on the bottom of said body, laterally extending ribs on opposite sides of said body, and a screen extending between said ribs and lug and along the lower portion and sides of said body and over said inlet port, said ribs. and lug reinforcing said body and maintaining said screen spaced from the sides and bottom thereofwhereby oil may flow to said inlet port from three directions during operation of the pump and the screening area is substantially wider than said bottom. a

3. In a railway journal lubricator, a pump, a discharge chamber at the end thereof, a discharge sleeve telescopingly assembled with said chamber, a discharge cup carried on the upper end of said sleeve, 2. spring supporting said sleeve in said chamber, said sleeve and cup having a concave-convex engagement with each other whereby said cup may assume various angular positions relative to said sleeve to facilitate contact between said cup and the journal, to be lubricated, and a hollow rivet loosely holding said cup and said sleeve together.

4. In a railway journal lubricator, a body arin Y ranged to rest on the bottom of a journal box, said body having an upwardly disposed chamber at its inner end, a spring mounted journal-contacting element telescopingly supported above said chamber, and a supporting rib on the bottom of said body between said chamber and the outer end of said body for engaging the bottom of the journal box the inner end of said body being tiltable downwardly about said rib as a pivot when the box is jacked up far enough to force said element to the limit of its telescoping movement relative to said chamber.

5. In combination, a railway journal, a journal box mounted thereon the central portion of the lower wall of said box being offset upwardly, a lubricator body mounted on the center of the main portion of the bottom wall of said box, a pump piston rod projecting from said body, a pin extending transversely of said rod and journaled on said body, a crank depending from said pin in front of said rod, and an operating lever extending forwardly and upwardly from the end of said pin at the side of said offset portion of the box lower wall and then transverse- 1y to engage the end of said journal.

6. In a railway journal lubricator, a pump cylinder adapted to be applied beneath the journal, an upwardly disposed discharge chamber adjacent said cylinder for conducting lubricant to the journal, and a passageway leading from said cylinder to the lower portion of said chamber, said passageway being inclined downwardly towards said chamber to prevent the return of lubricant therethrough to said cylinder.

7. In a railway journal lubricator, a pump cylinder adapted to be applied beneath the journal, a lubricant receiving chamber adjacent said cylinder, a passageway connecting said cylinder and said chamber, a check valve in said passageway, a lubricant discharge passage adjacent said chamber, and a conduit connecting said chamber and said discharge passage and disposed downwardly towards said passage to prevent the return of lubricant therethrough to said receiving chamber where it would impede the operation of said check valve.

8. In a railway journal lubricator, a pump body adapted to be seated on the bottom of a journal box, a discharge conduit forming a passage for leading lubricant from said body upwardly towards the journal, said conduit having an upwardly facing spherical surface at its upper end, a discharge cup carried solely by said conduit and having a downwardly facing spherical surface forming a universal joint with the spherical end of the conduit, and a hollow rivet disposed axially of said conduit and loosely securing together said conduit and sleeve and forming part of said discharge passage.

9. In combination, a railway'journal and a journal box, a pump body resting on the bottom of said journal box, said body having a reinforced end portion including an upright chamber, a spring supported journal contacting element telescopingly mounted in said chamber, and supporting ribs on the bottom of said body and maintaining the same spaced from the bottom of said journal box, said ribs being on the same side of said upright chamber and spaced therefrom whereby, when said box is jacked up far enough to force said element to the limit of its telescoping movement into said chamber, said body may tilt about one of said ribs to bring said journal and box bottom closer together and cause said reinforced end portion to engage said box bottom so as to assist in resisting bending forces applied to said pump body.

10. In combination, a railway journal and a journal box, the lower wall of said box having an upward offset substantially beneath the outer end of said journal, a lubricator pump body mounted on said lower wall and terminating adjacent said offset and having a piston in line with said offset, and a pump operating crank with an arm in line with said piston and disposed sidewardly of said body and said offset and then upwardly over said offset and engaging the end of said journal.
