EGBERT B. BROWN, DE LOS ANGELES, CALIFORNIA.

JOURNAL-LUBRICATOR.

To all whom it may concern:

Be it known that I, EGBERT B. BROWN, a citizen of the United States, and resident of the city of Los Angeles, county of Los Angeles, State of California, have invented certain new and useful Improvements in J ournal-Lubricators, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 is a longitudinal vertical sectional view of the car journal box showing the lubricator in side elevation; Fig. 2 a transverse sectional view of the journal showing the lubricator applied, a portion of the lubricator frame being broken away to more clearly show its construction; Fig. 3 a plan view of the flexible basket, a portion being broken away to more clearly show its construction; Fig. 4: a perspective view of the lubricator supporting frame; Fig. 5 an edge view of one of the lubricating mats; Fig. 6 a detail perspective View of the mat fastening means; and Fig. 7 a detail sectional view showing the manner of fastening the lubricator mat to the basket and the basket to the supporting frame.

This invention relates to lubricators for railway car journals, electric car journals, and other forms of journals. It is an improvement in that class of lubricator-s in which a lubricating mat or pad is supported in contact with the journal by a troughshaped basket, the basket being supported by a suitable resilient frame removably inserted in the journal box, the basket being flexible and arranged to conform to the surface of the journal, whereby the mat will be shaped to the journal and will be held in contact with a larger portion of its surface.

The invention contemplates improvements in such lubricator as a whole; improvements in the supporting frame; in the basket for supporting the mat; and in the mat by which the oil is applied to the journal.

Referring to the various parts by numerals 1 designates the axle journal; said journal has its bearing in the axle box in the usual manner. As herein shown this box is of the usual shape and contains in its uppermost portion the bearing brass 3 against which the journal rotates. The box is shown as recessed at 4 at its inner end to contain the usual dust guard 5 of wood or other suitable material. It will be Specification of Letters Patent.

understood that these features form no part of my present invention and may be varied as desired.

The lubricator proper comprises a supporting frame 7 which is formed of spring wire and is designed to resiliently support the basket 8 and to yieldingly press the same up around the journal 1. This supporting frame is formed of two parallel side bars or reaches 99 to which the longitudinal edges of the basket 8 are secured in a manner which will be hereinafter described. At each end of the reaches the spring wire of which the frame is formed is bent downwardly at right angles to form the shortvertical portions 10, and at the lower ends of these vertical portions the wire is bent inwardly and then brought upward and around to form the coils ll. From the lower sides of these coils the wire is carried inwardly and downwardly to a point directly below the opposite ends of the reaches to form the inclined resilient supporting legs 12. The legs on each side cross each other at a point directly below the center of the reach and about 'midway the height of the lubricator frame. The lower ends of the legs on one side of the lubricator frame are connected with the lower ends of the corresponding legs on the other side of the frame by means of transverse horizontal cross bars 13. As this supporting frame is formed of spring wire of the proper gage and temper it will be readily understood that it forms an exceedingly resilient support for the basket, the coils l l permitting the frame to be collapsed vertically under pressure and restoring it to its normal position whenever the pressure is removed. It will be noted that as the lower ends of the legs 12 are free to slide on the bottom of the journal box either end of the basket may be depressed without materially altering the height of the opposite end of the basket. This is of advantage as it permits the basket to follow the journal in all its vibrations which are considerable when the car is running over rough or uneven tracks. This feature is also of advantage when the car is rounding curves because of the inclination of the tracks, as it permits the basket to adjust itself to whatever variation there may be in the relative positions of the journal and the bottom of the journal box. It will also be noted that the two sides of the frame 7 are connected together only at the lower ends of the legs. This permits the frame to be expanded laterally at the top to enable the basket to adjust itself to large journals. This feature is of importance as it permits of the automatic adjustment of the lubricator to journals of various sizes, the upward pressure of the spring frame being sufficient to accomplish this automatic adjustment. The cross bars 13 give the lower part of the frame sufficient strength to enable it to resist whatever lateral strain is brought on it. To give the frame additional strength, coils 1e are formed at the junction of one cross bar 13 with one pair of legs 12. The frame is formed of wire and the sides thereof are unconnected at their upper end by rigid or metallic cross bars to enable the lubricator to be readily passed into journal boxes.

The basket 8 which carries the lubricating mat is formed of two rectangular pieces of strong closely woven fabric, preferably canvas, which form basket sections15, each of which is turned over and hemmed along its longitudinal edges, as at 16, to receive the spring steel marginal wires 17. These basket sections are arranged a short distance apart to form the opening 18 between them and the ends of the adjoining marginal wires 17 are connected together by chain links 19 so that the two basket sections are flexibly connected together.

To secure the outer longitudinal edges of the basket sections to the reach wires 9 of the supporting frame, clamping strips 20 are employed. These clamping strips are formed of sheet metal and are bent or folded over the reach wires and receive between their folded edges the outer longitudinal edges of the basket sections. Eyelets 21 are passed through the clamping strips near their edges and through the fabric of the basket sections, as shown clearly in Fig. 7, and permanently connect the basket sections to the supporting frame. It will thus be seen that an exceedingly strong and flexible basket is produced, the fabric being pivotally secured to the reach bars so that it will readily fold and conform to the cylindrical journal and permit the lubricating mat to be pressed closely against the journal. It will also be noted that the basket will be automatically adjusted to the journal by the upward pressure at its longitudinal edges and will, therefore, bring a greater area of the lubricator mat in contact with the journal than could possibly be secured by means of stiff non-resilient basket.

The lubricator mat is formed of two sections 22 which are equal in width to the length of the basket and are of sufficient length to extend from the upper longitudinal edges of the basket down through the opening 18 between the basket sections and to the bottom of the journal box, as shown clearly in Figs. 1 and 2. Each mat section is preferably formed with an upper soft wearing surface 23 of long fiuffy animal and vegetable fiber such as wool and cotton and a woven stronger vegetable fiber under-body or backing 24, the two bodies being interwoven in any suitable manner as by knitting or weaving. The two bodies forming what may be termed a tufted or pile fabric with the free ends of the fiber extending upwardly and outwardly from the underbody or backing 2 L. One longitudinal edge of each mat section is detachably connected to the basket near the upper longitudinal edge thereof just below the reach wire 9. For this purpose I provide the connecting bar 25 which is provided with fastening fingers 26.

These fingers are spaced apart to correspond with the positions of the eyelets 21 and to secure the mat sections in place they are passed through the mat sections, through the eyelets 21, their outer ends being bent over against the outer surface of the basket, as shown clearly in Figs. 1 and 7. By this means the mat sections may be readily removed by removing the connecting bar 25. The mat sections are of sufiicient length to permit their free edges to hang down through the opening 18 and rest on the bottom of the journal box, these depending portions of the mat sections forming feeders by which the lubricating -material is drawn from the bot-tom of the journal box up to that port-ion of the mat which is in cont-act with the journal. By reference to Fig. 2 it will be noted that the fibers of the wool por tion of the mat, where the mat cont-acts with the journal, are substantially radial to the car journal so that. the ends of said fibers bear on the journal. This is very important as the fiber in this position will be worn at its ends and the mat will last until the entire length of the fiber has been worn down. This will materially increase the life of the mat and prevent heating and the consequent carbonizing of the fiber.

By forming the mat sect-ions as described when the upper portions thereof become worn they may be reversed and the unworn sections be brought to bear on the journal, the worn sections being arranged to extend down into the journal box to act as feeders.

The resiliency of the lubricator frame provides for the lateral movement of the rotating journal, the jar of the axle and the movement of the box in starting and stopping, and makes it absolutely impossible for the journal to get away from the oiled lubricator mat; hence it renders a perfect lubrication at an infinitesimal cost.

The lower ends of the lubricator mat sections serve to prevent the oil sloshing backward and forward in the journal box.

It will be readily understood from the foregoing that the lubricator may be readily placed in a journal box and withdrawn therefrom. The spring supporting frame will be collapsed and when in position it will hold the mat sections pressed against the car journal with just sufficient force to insure perfect lubrication with the slight amount of pressure and the consequent wear of the mat.

It will be understood that I avoid the use of the ordinary waste. Practical tests have shown that my lubricator effects a saving of fifty per cent. in the use of oil; fifty per cent. of the amount of oil used in the ordinary lubricating journal boxes in which waste is used, besides effecting a saving of fifty per cent. in the wear of brasses and a great saving in the amount of labor in packing a journal box.

The journal lubricator is practically indestructible; may be cheaply manufactured and is extremely simple in construction.
