LUBRICATOR FOR JOURNALS.

SPECIFICATION forming part of Letters Patent No. 770,684, dated September 20, 1904,

Application filed December 24, 1900. Serial No, 40,951. (No model.)

To all whom it wtay concern:

Be it known that I, GEORGE F. GoDLEY, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Lubricators for Journals, of which the following is aspecification.

It is the object of the present invention to provide a light, durable, and comparatively inexpensive oiler for axle-boxes that will give thorough satisfaction in usage under all conditions and that will lubricate the journal freely and properly by means of a lubricator hereinafter pointed out.

The invention consists of the improvements hereinafter described and claimed.

The nature, characteristic features, and scope of the invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which- Figure 1 is a longitudinal sectional view of a car-axle box embodying features of the invention and illustrating a lubricator, and Fig. 2 is an end sectional view of a portion of Fig. 1.

In the drawings, A is the car-axle box, B is the journal of the axle, and C is the bearing or block.

Located beneath the journal B is-a lubricator provided with a plate B, curved to fit the under side of the journal B. This plate has an extension or sleeve forming a tubular opening to accommodate a piece of absorbent material E-for example, felt. This felt is provided with an opening, as shown, to permit the oil to flow into the interior of said felt.

F is a spring adapted to hold the plate D up against the journal and to also provide for the jars that occur when mounted upon a moving car. The journal when in action revolving over the opening in the felt causes a vacuum in the same and causes the oil to pass very freely into the interior of the felt. The oil is absorbed by the felt and is carried to and lubricates the journal; but should said felt become inoperative oil may pass to the journal through the interior of the felt. This is possibly by reason of the fact that there is a vacuum created in the interior of the felt and that there is also a pressure of fifteen pounds to the square inch of atmospheric air on the surface of the oil inthe journal-box. This construction of using both felt and vacuum passage insures a reliable device, and in case one ceases to operate properly the other is still able to lubricate the journal.

A lining of felt or other material, as M, may be secured on the plate D, or, if desired, it may be lined with plumbago.

Such an oiler or lubricator as has been described supplies oil very freely and thoroughly lubricates the journal. Such a construction is simple and will not easily get out of order and is capable of being readily replaced. It is light, strong, and durable and in manufacture is comparatively inexpensive.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in detail without departing from the spirit thereof. Hence I wish it understood that I do not limit myself to the precise construction and arrangement of parts as hereinbefore set forth; but,

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of an axle-box constructed to contain oil in the bottom thereof, a journal within the box, a lubricator provided with a plate conforming to the shape of the journal and provided with a downwardlyprojecting sleeve, a piece of felt conforming to the shape of sleeve and contained within the same, and a spring located between the box and the plate for keeping said plate in contact with the journal, substantially as described.

2. The combination of an axle-box constructed to contain oil in the bottom thereof, a journal within the box, a lubricator provided with a plate conforming to the shape of the journal and provided with a downwardlyprojecting sleeve of circular cross-section, a similar-shaped piece of felt fitted to said sleeve and provided. with a vacuum oil-chamber and a spring surrounding the said sleeve and located between the bottom of the axle-box and plate, substantially as described.

3. The combination of a box having an oilreservoir in the bottom of the box, a journal within said box, an oil-receiver impinged against the under side of the journal, a sleeve projecting downwardly from the oil-receiver, the lower end of which is submerged in the oil and felt or other absorbent material Within the sleeve and forming a vacuum oil-chamber substantially as described.

The combination of a journal-box constructed to contain oil in the bottom thereof, a journal within the box, a lubricator provided with a plate conforming to the shape of the journal and provided with a downwardlyprojecting sleeve, absorbent material contained within said sleeve, and a spring located between the box and plate, substantially as described.

5. The combination of a journal-box having an oil-reservoir in the bottom thereof, a journal within said box, an oil-receiver conforming to the shape of the journal, a sleeve projecting downwardly from said receiver, the lower end of which is submerged in the oil and absorbent material contained within said sleeve whereby dust and dirt are prevented from coming in contact with the absorbent material, substantially as described.

6. In combination an oil-reservoir, a lubricator comprising a plate forming an oil-receiver,'a sleevedepehding from said plate, absorbent material, forming an oil-well and serving as a vacuum chamber, fitted within the sleeve and a spring between the reservoir and the plate, substantially as described.

7. The combination of a journal-box constructed to contain oil in the bottom thereof, a journal within the box, a lubricator provided with a plate conforming to the shape of the journal and provided with a downwardly-projecting sleeve, absorbent material contained within said sleeve and between the plate and journal, and a spring located between the box and plate, substantially as described.

In testimony whereofI have hereunto set my hand and affixed my seal.

GEORGE F. GODLEY.
