WITNESSES ATTORNEY UNET JOSE MARIA. URBIETA, LAREDO, TEXAS JOURNAL-LUBRICATOR.

Specification of Letters Patent.

Patented July 3, 1917.

Application filed July 12, 1916. Serial No. 108,899.

To all whom it may concern Be it known that l. Josh M. Unninra, a citizen of the United States, residing at Laredo, in the county of \Vcbb and State of Texas, have invented certain new and useful Improvements in Journal-Lubricators, of which the following is a specification.

This invention has relation to lubricating devices for railway car journal boxes, and thenature and objects thereof will be readily apparent to those skilled in the art to which it appertains. in the light of the fol lowing explanation of the accompanying drawings, illustrating what I now believe to be the preferred embodiment, or mechanical expression of my invention from among other forms and arrangements thereof within the spirit of the invention and the scope of the appended claims.

However, an object of the invention is to provide a device for effectively and continuously lubricating the journal of a railway car axle, without the use of waste, packing or imilar expedients heretofore employed for this purpose. and embodying means for applying the lubricant to the surface of the journal uniformly, and throughout its length, in a new and novel manner.

Another object of the invention which follows from the foregoing, is to provide a lubricating device having the above named characteristics and adapted to be inserted within the standard journal box and having means for suspending the device therein in proper relation to the journal.

In addition to the foregoing, my invention comprehends improvements in the details of construction and arrangement of parts to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings, in which similar and corresponding parts are desig nated by the same characters of reference throughout the several views in which they appear:

Figure 1, is a vertical sectional view taken through a standard journal box, illustrating the application of my invention thereto.

Fig. 2, is a vertical sectional view taken on the line 22 of Fig. 1.

Fig. 3, is an end view of my device per 86.

Fig. at, is a transverse sectional view taken on the vertical plane indicated by the line 41 of Fig. 1.

Fig. 5, is a view in front elevation of a journal box in whiclrmy device has been secured by means of a modified form of sup port. and

Fig. 6, is a vertical sectional view taken on the line (3 6 of the foregoing figure.

With reference to the drawings, 1 indicates a journal box in which is received the journal 2', adapted for frictional engagement with the brasses 3, which in turn are secured in place and in proper relation to the journal by means of a wedge block l, interposed between the brasses and the upper portion of the journal box.

My invention comprises in its essentials. a reservoir, 5 adapted to be placed beneath the journal. to ext-end approximately from end to end thereof. The reservoir elongated in conformation and has its opposed longitudinal edges curved upwardly and inwardly as at 6, defining in cross section substantially semispherical pockets. The ends of the reservoir are bent toward each other to form horizontal ledges T, the terminals of which are bent downwardly at 8 and then horizontally in opposite directions at 9. The forward portion of the reservoir, or that portion adjacent the opening in the journal box, is formed integrally with a conduit 10, providing communication between the interior of the reservoir and funnel 11 or the like located so as to be readily accessible through the journal box opening.

Lubricating rollers, in the present instance two of which are provided, are formed of wire coiled to spiral form, with the ends of thewire bent to form journals 12, which are in alinernent with each other and with the central longitudinal axis of the roller. The rollers 13 are concentrically disposed within the semi-circular pockets defined by the longitudinal edges of the reservoir, the journals 12 of the rollers being mounted for rotation in openings formed in each of the vertical portions 8 of the end walls of the reservoir.

The reservoir may be supported by means of a hanger constructed of wire and comprising semi-circular strands 1 1, encircling the journal at its forward end, having their upper ends bent horizontally as at 15 and engaged in a space provided between the brasses 3 and the wedge block l. The lower terminals of the strands forming the hanger are bent substantially horizontally as at 16 in more or less of an arc, and having the extremities formed with eyes 17 engaged in eyes 18 formed on the terminals of a supporting wire or rod 1.9 extending transversely beneath the reservoir. The resiliency of the members of the hanger, serve to press the device upwardly so as to dispose the convolutions of the rollers 13 in close contact with the under surface of the journal. ()il may be supplied to the reservoir through the filling opening 11, and during rotation of the journal, it will be obvious that the rollers will be likewise rotated through frictional contact. The lubricant is carried by the convolutions of the rotating rollers to the journal thereby lubricating the same throughout its circumferential surface and from end to end. The reservoirs may be quickly and easily replenished without disturbing the relation of the same to the journal.

In journal boxes, which by reason of their construction do not permit the use of the hanger described above, I provide a hanger of another form illustrated in Figs. 5 and 6. In this form of hanger, a single strand of wire is employed, bent upon itself to form parallel strands, with the bent portion again bent as at 20 thus providing a hook member designed to engage over the lower edge of the journal box opening. The bent portion may be formed with an out-turned bend 21 thus providing a finger piece by which the hanger may be disengaged from the journal box. The strands of the hanger are adapted to engage the lower curved portion or bottom of the journal box, and accordingly are curved as at 22 to conform to the curvature of the bottom at that point. The terminals of the strands are then curved upwardly at 23', formed at their terminals with eyes 24 and engage by means of said eyes with eyes -25 formed on the ends of a transverse rod disposed beneath the reservoir.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations reservoir, means in the reservoir for supplya ing lubricant to the journal, and means held by the brasses and wedge block for suspending the reservoir in proper relation to the journal.

2. A lubricating device for journal boxes, comprising a reservoir adapted to extend from end to end of the journal having its longitudinal sides curved outwardly, depending flanges formed at either end of the reservoir, with openings provided in said flanges, an extension formed on one end of the reservoir, an enlarged portion onthe end of the extension to form a funnel, whereby the reservoir may be filled, and lubricating rollers within the reservoir each comprising a strand of wire, curved spirally to form a plurality of closely spaced convolutions, with the terminals of the wire extended in opposite directions and in alinement with the central axes of the roller whereby the rollers may be supported in the openings of the flanges for rotation to carry lubricant to the journal.

In testimony whereof I affix my signature in presence of two witnesses.
