Figure 4 is a view corresponding to Figure 1 but drawn on a smaller scale and illustrating the manner of application and removal of the distributor to and from the journal.

The journal I forms the end portion of the axle and is provided with a collar 2. The box has side walls 3 and a bottom Wall 4 with its outer edge 6 vof the box opening 1. The lubricator pump comprises a substantially rigid body portlon 8 resting on the box bottom wall and having inven'tionli's ?to' construct l :a distributor of substantial area i so that -'it rnay wber 12,1943.

"The journal and box :parts illustrated are of ordinary construction. The pump parts illusdmat'ed are vdisclosed in an earlier application filed :by' the present "inventor June 1, 1942, Serial "No. -4'4i5;299, now Patent iNo. 1331;835, issued Octo- Mounted on the pump body is a distributor unit comprising alower arm having anallshaped terminal seated in a-socket in thetop of :thepump and-a plate N5 of cruciform outline and-r aconcave-upper surface provided-with ridges ar ranged to contact with the lower face of the "journal.

Associated with parts 14 and I 5 is an extension structur including -a central *frame comprising a channel-like plate 2| with downturned flanges 22 projecting longitudinally of the device beyond the ends of the plate. A coil spring 23 is compressed between seat ltand the lower face of plate 2! to thrust the latter upwardly against the bottom of plate I5. Plate 2| has a central end curved upwardly as at 5 to form the lower hole H through which spring 28 extends to enage its seat I9.

,A pan-like member 24 surrounds each end arm of plate I5 and extends lengthwise of the device beyond the arms. Each member 24 has a U- shaped reenforcing angular strip 25 with the upright flanges of the legs of the strip extending alongside the outer portions of flanges 22 and pivoted thereto at 26. The horizontal flanges of the legs of each U and the adjacent portion of the pan member extend beneath the lower edges of flanges 22 and limit the downward movement of the outer portions of the pan members about their pivots 26. The outer ends of the pan members are free to swing upwardly from the horizontal position shown in Figure l to the position shown in Figure 4 to facilitate the insertion and removal of the distributor through the end opening in the box and while the journal and the box are still assembled.

A series of felt pads 21 are held together by bolts 28 and are carried in members 24. Some of the pads have depending cars 29 inserted through slots 3!) in pans 24 to maintain the assembly of the pads and their carriers when the device is not in place in a journal box. The contour of these pads is such that their upper edges are thrust against the lower portion of the journal and the pads absorb oil discharged from plate l5 and, when saturated, distribute thisoil to the journal, thus providing an even supply of oil throughout substantially the entire lower portion of the journal.

With this construction, the rigid central distributor plate I5 and the carrier supported pads are yieldingly thrust against the journal to provide uniform contact throughout the area of the distributor and irrespective of variations in the manufacture of the parts which may be formed without substantially machining or fitting and irrespective of the relative positions of the pump and journal in the box. The device is simple and the parts are held in functioning position by the two helical springs, each spring supported part being movable independently of the other. As indicated above, the parts are readily inserted and removed into and out of functioning position.

The details of the structure may be varied without departing from the spirit of the invention, and the exclusive use of those modifications of the described structure which come within the scope of the claims is contemplated.

What is claimed is:

1. In combination with a device for lubricating a railway journal and including a rigid distributor plate of restricted area for application to the journal and provided with supporting means, felt pads disposed to engage the journal at the sides of said plate, and structure yieldingly supporting said pads independently of said plate and means and comprising a frame and pad carriers mounted thereon and a yielding support for the frame and carriers, the mounting of the carriers on the frame providing for the inclination of said carriers and the pads thereon relative to said plate and frame and relative to each other to facilitate the insertion and removal of the plate, frame and pads through the space between the journal and the bottom of the box to which it is applied.

2. In a device for lubricating a railway journal, a horizontally disposed frame defining an opening adapted to receive the support for a central distributor applied to the journal, a yielding support for the frame applied thereto at opposite sides of said opening and arranged to clear said distributor support and to thrust the frame towards the journal, a pad carrier normally extending horizontally lengthwise of the frame beyond each end of the latter and pivoted to the franie to swing upwardly about each end of the frame to facilitate application and removal of the device through the restricted space between an axle journal and box, and means securing said carrier against pivotal movement downwardly from a normal horizontal position.

3. In a device for lubricating a railway journal, a central frame member consisting of a channel having a, horizontal web and downturned flanges, the flanges extending longitudinally of the device beyond the ends of the web, there being an opening of substantial area in said web for receiving a separate distributor part extending from below the device upwardly towards the journal, a yielding support for said frame, pads for application to a journal, carriers for said pads comprising pan-like members extending longitudinally of the device beyond said frame and having horizontal arms extending inwardly from the ends of said frame and abreast of said channel flanges, pivots through said arms and flanges at points spaced substantially from the inner ends of said arms, and interengaging elements on the inner ends of said arms and the adjacent portions of' said frame for limiting the pivoting movement downwardly of the outer portions of said members.

4. In combination with a device for lubricating a railway journal which includes a rigid distributor plate of restricted area for application to the journal and having a downwardly inclined conduit hinged at one side and terminating at its lower end in a portion arranged to rest on a pump body and provided with a spring between said plate and conduit for thrusting the same apart; a horizontally disposed frame apertured to surround said spring, carriers hinged to the ends of said frame and extending outwardly therefrom, fibrous pads mounted on said carriers to engage the journal outwardly from the edges of the distributor plate, said carriers being pivoted on said frame to swing upwardly on their pivots from a normal horizontal position but being held against swinging downwardly from said position, and a spring arranged to seat on said conduit portion and to engage said frame to hold said pads against the journal.
