OILING DEVICE FOR AXLES.

SPECIFICATION forming part of Letters Patent N 0. 790,451, dated May 23, 1905.

Application filed November 17, 1904:. Serial No. 233,179.

T0 at whom it may concern:

Be it known that I, CLAUDE M. MOFARLAND, a citizen of the United States, and a resident of South St. Joseph, Buchanan county, and State of Missouri, have invented certain new and useful Improvements in Oiling Devices for Axles, of which the following is a specification.

The presentinvention relates to an improvement in lubricating devices for car-axle jour-' nals, and has for its object to provide a simple and durable means for effectively lubricating such journals.

' 1n the accompanying drawings, Figure 1 is -a suitable opening formed in the rear wall of the journal-box 2. This box differs from the boxes heretofore commonly employed in that its outer end is closed by a swinging door 3, the dimensions and form of which are such that when the door is swung into the position shown in Fig. 2 the entire outer end of the box is opened.

A removable lubricant-receptacle 4 is adapted to be inserted in the box through the opening at the outer end thereof when the door 3 is in the position shown in Fig. 2, said receptacle being preferably supported on ribs or projections 5, rising from the bottom of the box. As shown, the receptacle 4-.is preferably provided with side walls of such height as to extend above the horizontal plane of the lower face of the journal'l, recesses 6 being formed in the end walls of said receptacle, through which the journal can extend.

A wick-support comprising two parallel rollers 7 and an intermediate concave plate 8 are detachably mounted within the receptacle 4:, the rollers being so arranged as to lie on opposite sides of-the vertical plane, including the axis of the journal, when said receptacle is within the box 2. As shown, said wicksupport is mounted in suitable bearings formed in the free ends of inwardly-extending arms 9 of spring-brackets, which have vertical members extending into guides formed at the corners of the receptacle 4:. Said guides are formed by angle-plates bent to provide flat sections 10 11, adapted to be secured, respectively, against the end and side walls of the receptacle 4, the adjacent ends of said plates or sections being connected by a curved portion 12'. Each of the aforesaid spring-brackets may be formed from a single piece of spring-wire coiled or bent upon itself at an intermediate point to provide the two arms which extend substantially at right angles to each other. vided with suitable barbs or spurs 13, which engage the body of the endless wick 15,- and each roller is provided at its outer end with a head or enlargement 16, by means of which the roller can be rotated in its bearings to move the wick transversely of the journal 1.

The wick is preferably of such length as to extend from the support therefor substantially to the bottom of the receptacle 4 and into the liquid lubricant placed within such receptacle. Such lubricant will by capillary attraction be conducted upwardly to the portion of the wick on whichthe journal bears. If at any time it is desired to bring another portion of the wick beneath the journal, the rollers 7 can be readily rotated, the heads 16 lying outside of the receptacle 4:, as shown in Fig. -l.

A dust-guard 17, consisting of two telescoping sections, is arranged about the journal in rear of the lubricating device, the members of such guard being pressed sufficiently close upon the journal to prevent the entrance of dust by means of springs 18,

The operation and ad vantage of the lubricating device herein described will be apparent. It will be seen that the invention provides a relatively large lubricating-surface for the journal, extending practically throughout the length thereof, and that if for any reason one section of the wick becomes un- As shown, the rollers 7 are pr0 suited for use by turning the roller 7 a fresh surface can be brought into operative position. The entire lubricating device can be readily removed from the box 2, and by making such box in the manner illustrated and described it is possible to use a receptacle adapted to contain a relatively large amount on said frame on opposite sides of the vertical plane of the axis of said journal, and provided with means whereby they can be rotated in said bearings independent of any movement of the journal and while in operative position relative to the journal, and a wick extending over and engaging said rollers.

2. The combination with a car-axle journalbox, having an opening at one end, and means for closing said opening, of a lubricant-receptacle adapted to be removably inserted in the box through said open end, an endless Wick supported by and extending into said receptacle and adapted when said receptacle is in position in the axle-box to bear against the under surface of the axle-journal, and means independent of the axle-journal for moving said Wick to bring any desired portion thereof into contact with the journal.

3. The combination with a car-axle journalbox, of a lubricant-receptacle adapted to be removably inserted in the box, yielding frames supported adjacent the ends of said receptacle, a rotatable wick-support mounted in bearings in said frames, and an endless wick extending over said support and into the receptacle on opposite sides of said support.

4. The combination with a car-axle journalbox, of a lubricant-receptacle adapted to be removably inserted in the box through an opening in an end wall thereof, a wick-support comprising two parallel rollers and an intermediate concave plate, means for detachably connecting said support to the lubricant-receptacle to bring the concave plate thereof beneath the axle-journal when said receptacle is in position within the box, and an endless wick carried by said wick-support and extending across the upper face of said concave plate and into the receptacle on opposite sides of said support.

5. The combination with an axle-journal, of a box having in its rear wall an opening through which said axle-journal extends and having its front wall formed by a swinging door, a dust-guard arranged within said box to close the portion of the opening in the rear wall thereof about said journal, a lubricantreceptacle adapted to be removably inserted in the box through the opening at the front end thereof, an endless wick supported within said receptacle in position to contact with the lower surface of the journal, and means for rotating said wick to bring any desired portion thereof into contact with the journal.

6. The combination with a car-axle journalbox, of a lubricant-receptacle adapted to be removably inserted in the box, a wick-support comprising two parallel rollers, spring-arms mounted in holders secured to the inner faces of the walls of said lubricant-rece itacle and having at their free ends bearings for said rollers and an endless wick extending over said rollers.

7. The combination with a car-axle journal and a box for said journal adapted to contain liquid lubricant, of two rollers supported within said box, means arranged between the free end of the journal and the front of the box for rotating said rollers, and a wick extending over said rollers and below the same into the lubricant-containing portion of the box.

8. In a car-axle lubricating device, the combination of alubricant-receptacle adapted to be removably inserted in a car-axle box, a pair of arms extending inwardly from each of the side walls of said receptacle, rollersjournaled in hearings on said arms, and a wick extending over said rollers and below the same into said lubricant-receptacle.

9. In a car-axle lubricating device, the combination of a lubricant-reeeptacle adapted to be removably inserted in a car-axle box, arms supported by the side walls of said receptacle and each formed of a single piece bent upon itself to provide at its upper end a substantially horizontal spring-arm that extends inwardly from the wall of the lubricant-receptacle by which it is supported, rollers mounted in bearings near the free ends of said horizontal arms, and a wick extending over said rollers and below the same into the lubricantreceptacle.

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