AUTOMATIC CAR-OILER.

Specification of Letters Yatent.

Patented Feb. 18, 1913.

Application filed October 1. 1912. Serial No. 723,322.

To all whom it may concern Be itknown that-T, Jonx T. McRnvsoLns, a citizen of the United States, and a resident of Lilly, in the county of Tazewell and State of Illinois, have invented a new and Improved Automatic Car-Oiler. of which the following is a full, clear, and exact description.

This invention relates to improvements in oiling systems in a car journal box. and has reference more particularly to a device of the class which comprises a casing and a member in the casing carried by the rotat ing axle having means to supply the oil contained-in the casing to the surface of the axle bearing.

The object of the invention is to provide an inexpensive automatic car oiler, simple in its construction and efficient in its action, inclosed in the car journal box, and the efficiency of which is independent of the direction of rotation of the axle.

Another object of the invention is to provide an oiling system having a non-abrasive material saturated with oil in contact with the bearing surface of the axle, the saturation of non-abrasive material being performed by a continuous supply of oil to same.

The invention consists in the construction and combination of parts to be more fully described hereinafter and fully set forth in the claims. 7

Reference is to be had to the accompanying drawing forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views, and in .which- Figure 1 is an elevated contral section of a car journal box incorporating an embodimentof my invention; and Fig. is a section through line 22, Fig. 1. H

Referring to the drawin 10 is the bearing end of a car axle of the customary form and design bearing against a well known type of the ordinary bearing piece 11, maintained in position in the customary type of car journal box 12. he car journal box 12 is provided with an opening closed by a cover 13. Fitted into the journal box 12 is a casing 14:, preferably formed of sheet metai. having an aperture provided with a hin ed cover 15 registering with the cover 13 of the journal box. Through this opening. oil is introdu ed into the lower part of the casing, and through same inspection of the function of the device is made. The casing let provided with a semi-circular pan or trough 16 surrounding the lower half of the bearing 10 and connected to the lower part of the casing by means ofstay members 17 and 18. The pan 16 is provided with a filler of some absorptive non-abrasive material 19, preferably cotton, bearing against the lower half of the bearing surface. An end wall is provided to the pan to force the oil flowing on the pan' to run toward the cotton filler 1t). Concentric with the bearing end 10. and in front of same and the forward end of pan. is a circular member 20 having a central aperture provided with dove-tail notches 21. Both faces of the central member 20 are provided with curved grooves 22, converging from the lateral surface toward the center and intended to convey the oil from the lateral surface to the center, the grooves on the opposite face being of same curvature and convexity, so that one face willscoop the oil when the member 20 rotates in one direction and the other face when rotated in the opposite direction, as can be easily seen from the drawing.

On each side of the central member 20 disks 23 are provided, so as to make the grooves pipe like. The disks have the same diameter as the central member, and the same central opening and dove-tail notches.

The central member and disks are fitted on a tubular member 24 provided with projections 25 engaging in notches of central member and disks and fitting snugly,in same so as to make a rigid connection between. The tubnlar member 24 is provided with apertures 26 onitslateral surface'registering with the grooves 22 in the central member 20, and same is rigidly attached to a shaft- 27 in any desired way. The shaft 27 is provided with longitudinal surface grooves 28 registering with the aperture 26 in the tubular member 24. The grooves are inclined toward and open at same end abutting against the end of axle 10 so that the oil running from curved grooves of member 20 through the apertures 26 of tubular member will flow in the groove 28 toward the abutting end of shaft 27. The

shaft 27 is centrally provided with a square bindingthe central shaft 27, tubular member 26 andcircular member with disk 22 with the end of axle 10.

The casing l linclosed in the journal box is provided with a top, so as to prevent oilbeing thrown against the top of casing of the journal box, and in the lower part, Where oil is maintained, an incline is provided, so as to lessen the volume of the oil required and have the same surface.

It can be easily, seen from the drawing that when the axle'rotates the circular member 20 rotated through the medium of its connections withthe'end of axle, as above described, will scoop the oil into the casing and convey it through .the groove toward the center and then through the aperture 26 of tubular member 24, which will fiow into the groove 28 ofshaft 27 toward the face of the end of axle 10 and there flow into the pan 16. The cotton in the pan absorbing the oil falling into it becomes saturated with same and, being constantly in contact with the lower half of the bearing surface, supplies same with oil. It can be easily seen from the drawing thatthe excess of satura tion will run off at the end of the pan op positethe one provided with a wall directly into' the casing, so that the action 'or supply is continuous. It may be also remarked that the circular member 20 with disks 23 when mounted on the tubular member 24 forms an elevator for the oil.

Having thus described my invention, what I claim and desire to secure by Letters Pat,- ent is:

1. A combination with a car journal box and a journal mounted therein, of a casing inclosed in said journal box and adapted to carry oil at its lower end,- said casing having a receptacle under the lower part of said journal, a circular elevator concentrically attached .to the end of said journal in said casing having a circular member grooved at each side, a. disk at each side of said'circular member and associated with same, said central member and disks having a central orifice, a tubular member fitted in said central orifice and having apertures on its lateral surface registering with said grooves on both sides of said circular member, and means in said circular member, disks and tubular member to bind same rigidly-together, said elevator being operated by said journal to convey the oil from said casing into said receptacle, and means in said receptacle to supply the oil to the bearing surface of said journal.

2. A combination with a car journal box and a journal mounted therein, of a casing inclosed in said journal box and adapted to carry oil at its lower end, said casing hav ing a receptacle under the lower part of said journal. a circular elevator concentrically attached to the end of said journal in said casing having a circular member grooved at each side. a disk at each side of said circular member and associated with same, said central member and disks .having a central orificc. a tubular member fitted in said central orifice and having apertures on its lateral surface registering with said grooves on both sides .of said circular member, and means in said circular member, disks and tubular member to bind same rigidly together, a shaft in said tubular member havinglateral grooves open at one end and registeri'ng with said apertures .in said tubular member. said end of said shaft abutting against the end of said journal, and means for binding said shaft with the end of said journal, whereby the elevator is Operated, and an absorptive, non-abrasive material in said receptacle contacting with the bearing surface of said journal.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
