Jose M. URBIETA, or DEL 10, TEXAS.

Application filed August 12, 1919,

1 b all whom it may concern Be it known that I, Josii M. URBLETA, a citizen of Mexico, residing at Del Rio, in the county of Valverde and State of Texas, have invented certain new and useful Improvements in Gar-Axle Lubric-ators, of which the following is a specification.

This invention relates to journal boxes for car axles of' the type embodying means for positively feeding lubricant to the journal so as to prevent overheating. The invention aims to improve the adjunctive parts of the journal box so as to simplify the construction and enable access to be readily had to the interior of the journal box for replacement or other purpose.

The invention furthermore aims to prevent waste of lubrican'tand to insure an ample supply of the lubricant to prevent the' Wearing parts from becoming dry and also to exclude dust and foreign matter from the wearing parts and lubricant the box being closed and the ournal protected so that dust is prevented from entering the oil reservoir and any surplus oil on the journal being disengaged therefrom and directed back into the reservoir to be again supplied by the oil feeding means.

The drawings illustrate a preferred embodiment of the invention. However, it is to be understood that in adapting the same to meet different conditions, various changes in the form, proportion, and minor details of construction may be resorted to without departing from the nature of the invention as claimed hereinafter.

The accompanying drawings illustrate an embodiment of the invention and on reference thereto;

Corresponding and like parts'are referred to in the following description and indicated in the several views of the drawings by like reference characters.

The journal box 1 may be of any ordinary construction, such as commonly employed in connection with car axle journals. The car axle journal 2 is mounted in the box 1 and the usual brass 3 and wedge 4 are mounted thereon in a manner well understood. A reservoir 5 is disposed within the lower portion of the journal box 1 and is supported upon a spring 6. Longitudinal ribs 7 are formed upon the under side of the reservoir 5 and have inwardly extending projections '8 at their outer ends which are adapted to enter notches 9 formed in opposite edges of the spring 64 The ribs 7 are spaced apart a the reservoir.

ceive a quantity of oil and is shallow and open at the top. An extension 11 is provided at the outer end of the reservoir 5 and is hollow and is designed as means to facilitate the filling of the reservoir when supplying oil thereto. The extension 11 projects upwardly a short distance in front of the journal 2 and its upper end is adapted to be closed by means of a cap 12. Av projection 13 depends from thecap 12 and is of length to extend into the filling extension 11 to within a short distance of the bottom of The projection 13 is provided upon one side with indicia to designate the quantity or level of the oil in the reservoir. The projection 13 within the indications thereon constitutes a 3i connection 14, such as a chain constitutes connecting meansbetween the projection 13 and the reservoir 5 to prevent displacementor loss of the cap or closure 1.2. This is shown most clearly in Fig. 2. v

A frame is placed upon the reservoir 5 and comprises longitudinal members 15 and transverse members 16. The longitudinal members 15 are formed with inner flanges or ribs 17 which touch the sides of the jour- V nal' 2, so' as to forms close joint therewith Cir to remove surplus oil and prevent dust or foreignmatter' from entering the reservoir. The lower edges. of the longitudinaland transverse members of the frame have a fab bet connection with the upperedges of the sides and end portions of the reservoir 5,

whereby the frame is retained in place and a close joint between the parts assured. 'The inner flanges or ribs 17 incline in opposite directions from a medial point, as shown most clearly in Fig. 4 to direct the lubricant received thereon toward opposite ends of the reservoir.

Openings 18 are formed in the endsof'the flanges or ribs 17 for the escape of'the oil to the reservoir. The 0penings 18 flare toward their upper or recelvleft in Fig. 4.

ing ends, as indicatedmost clearly at the The oil feeding means comprise rollers 19 and 20. The roller 19 is disposed at the inher or rear end of the reservoir 5, whereas the rollers 20 are'located at the sides of the reservoir and intermediate the ends thereof. The roller 19 is disposed in an inclosed space 21 and its outer edge has a covering of rubber, leather or like material applied thereto. The inclosed space 21 connects by means of an upwardly and outwardly inclined duct 22 with a trough formed at the longitudinal bar 15 of the said frame. A pivet pin 25 passes through the upper end of each support 24: and through ears 26 sembled. -This is shown most clearly in Fig. 11. v V

The brass 3 has extensions 29 at opposite sides to coact with'the hanger, not shown, in a manner well understood. closes the space formed betwe'enthe longitudinal bars 15 of the frame and the brass 3. This shield comprises side members 30 and end members 31 and 32. The end members 31 and 32 are upwardly curved to obtain .7

close fit on end portions of the journal and the. brass. One of the end pieces is made detachable to facilitate placing the shield in position or removing it from the brass.

A shield in-f The side members 80 have their lower edges engaging the upper edges of the longitin dinal members 15. The upper edge .cf'each. side member 30 obtains a close fit against the sides of the brass 3. The portion opposite the extension 29 is separated by inwardly extending cuts and bent inwardly, indicated at 33,50 as to pass beneath the extension with its inner edge engaging the side of the journal, as shown most clearly in Fig. The shield may be formed of any suitable sheet metal, such as steel, galvanized iron, or the like. I v i As is well known, the brasses 3 become rapidly worn and are required to be frequently replaced and in some instances it is I preferredto construct the brass and shield as one part by molding the brass with the shield. A construction of this kind is illustrat'ed in Figs. 15 and 16. The'shield, either of steel, iron, or the like, is placed in a mold and the molten brass cast, sons to have the inner portion of the shield embedded therein, thereby forming in: effect the brass and shield of one part and obviating loose joints. The side extensions 29 are disposed above the sides'ofthe shield, as indicated most clearly in Fig.16.

It will be understood from the foregoing taken in connection with theaccompanying drawings thatthe'invention results in the .p'rovisionof a journal box for car axles,

which involve a comparatively simple structure and which admits of replacements being readily and economically made and which' insures a positive feed of the lubricant. without entailing. any waste thereof and which enables the oil reservoir to be readily replenished when necessary, the quantity of oil in the reservoirbeing readily determined by means of the gage.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved, form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1.
