LUBRIOATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 763,599, dated June 28, 1904.

Application filed December 12, 1903. Serial No. 184,916- (No model.) I

To (LZZ whom it may concern:

Be it known that I, ALBERT G. ELVIN, of Franklin, in the county of Venango and State of Pennsylvania, have invented a certain new and useful Improvement in Lubricating Devices, of which improvement the following is a specification.

My present invention relates to journal-lubricators of the general class or type which is set forth in reissued Letters Patent No. 12,134, granted and issued to me under date of July '21, 1903; and its objects are to effect a structural simplification and afford improved'facilities for repacking the lubricant-cellaras from time to time required.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure l is a front view of a locomotive-driving-axle box, illustrating an application of my improvement; Fig. 2, a transverse central section through the same; Fig. 3, a longitudinal central section through the same; and Figs. 4 and 5 side and end views, respectively, of a device employed for facilitating the operation of repacking.

My invention is herein exemplified as applied in connection with a journal-box 2, which is adapted to be supported on the journal of a locomotive-axle and has the usual brass bearing 3 and lubricant-cellar 4, the lubricant-cellar being held in place by means of lugs 5 on the cellar 4, coinciding with lugs 6 on the journal-box 2, and a suitable rod 7, passing through eyes 8 of said lugs. It will be understood that the cellar 4 is an element in the journal-boxes now in use, in which cottonwaste soaked with lubricating-oil is usually placed for the purpose of lubrication of the axle. The passage-ways 10, which are ordinarily provided for additional lubrication from the well 9, are plugged up in journalboxes having my invention applied.

The top of the cellar4 is covered by a capplate 11, which is preferably of perforated sheet metal or may, if preferred, be of wirenetting and is curved transversely to approximately the radius of the journal 'on which the axle-box is carried. The plate 11 fits closely in the top of the cellar and is turned downwardly on its sides to form lateral flanges 11, which are supported on bearing-strips 2*, formed on or fixed to the inside of the cellar, and is also turned downwardly at its ends, as shown in Fig. 3.

A follower-plate 14 is fitted in the lower portion of the cellar and is pressed upwardly toward the cap-plate 11 by a spring 16, which is interposed between its lower side and the bottom ofthe cellar. The space between the cap-plate and follower-plate is,in the operation of the device, filled up by a solid block of lubrieating material 13, which is inserted through an opening at oneend of the cellar, which is closed by a removable lid 4, secu red to the cellar by bolts 4", and is continuously pressed up to and through the openings of the perforated cap-plate 11 and against the adjoining periphery of the journal by the spring 16 and follower-plate 14. The degree of wear of the lubricant is shown, and means for depressing the follower-plate to admit of repacking the cellar withllubricant when required are afforded by one or more indicator-rods 18, (two being shown in this instance,) which are connected to the follower-plate 14 and pass freely through openings in the bottom of the cellar 4, their lower ends being turned into eyes 18. The

indicator-rods may be notched or marked at different points in their length, so that the degree of upward traverse of the follower-plate,

due to the wearing away of the block of lubricant 13, may be readily observed. When the block has become so far used that it is deemed necessary or desirable to repack the cellar, the follower-plate 14 is drawn down to the bottom of the cellar by means of the rod or rods 18, the lid 4 taken off, and a fresh supply of lubricant inserted, after which the lid is replaced and the device is in condition for continued operation. The operation of repacking may be facilitated by the employment of the appliance for depressing the follower-plate 14 which is shown in Figs. 4 and 5, for the application of which the eyes 18 of the indicator-rods are adapted. This appliance consists of two hook-ended rods 22, which are fixed upon a bar 21 at such distance apart that they may engage the eyes of the indicator-rods. The bar 21 is adapted to ex- IOC tend across the pedestal-brace below the axle, and by pulling down upon it the operator is enabled to move the follower-plate to the bottom of the cellar and repaek the cellar, as above described, without the necessity of taking it down, thereby eeonomizing time and labor.

I claim as my invention and desire to secure by Letters Patent-- 1. In an axle-lubricator, the combination, substantially as set forth, of an axle-box eellar, an inwardly-curved cap-plate located at the top of said cellar and provided with downwardly-extendingflanges, bearing-strips fixed to the cellar and supporting said flanges, a follower-plate fitting the cellar below the capplate, and a spring interposed between and bearing on the bottom of the cellar and the lower side of the follower-plate.

2. In an aXle-lubricator, the combination,

, substantially as set forth, of an axle-box cellar,an inw ardly-curved foraminous cap resting on supports on the side walls of said cellar, a follower-plate fitting the cellar below the capplate, a spring interposed between and hearing on the bottom of the cellar and the lower side of the follower-plate, and a removable lid closing an end opening in the cellar.

3. In an aXle-lubricator, the combination, substantially as set forth, of an axle-box cellar, an inwardly-curved foraminous cap supported at the top of said cellar, a followerplate fitting the cellar below the cap-plate, a

spring interposed between and bearing on the bottom of the cellar and the lower side of the follower-plate, and a rod projecting downward from the follower-plate through the bottom of the cellar.

at. In an axle-lubricator, the combination, substantially as set forth, of an axle-box cellar, an inwardly-curved cap-plate supported at the top of said cellar, a follower-plate fitting the cellar below the cap-plate, a spring interposed between and bearing on the bottom of the cellar and the lower side of the follower-plate, a removable lid closing an end opening in the cellar, and means for manually depressing the follower-plate below the level of the end opening.

5. In an axle-lubricator, the combination, substantially as set forth, of an axle-box cellar, an inwardly-curved foraminous cap supported at the top of said cellar, a followerplate fitting the cellar below the cap-plate, a spring interposed between and bearing on the bottom of the cellar and the lower side of the follower-plate, a removable lid closing an end opening in the cellar, and a rod projecting downward from the follower-plate through the bottom of the cellar and having an eye on its outer end for connection with a depressing device.

ALBERT Gr. ELVIN.
