To all whom it may concern;

Be it known that I, WILLIAM H. FosTER, of Bayside, in the county of Queens and State of New York, have invented a certain new and useful Improvement in Journal- Boxes, of which improvement the following is a specification.

My invention relates to the ordinary type of journal boxes for the axles of railroad vehicles, in which type, lubrication is effected by oil supplied to thejournal from a packing of fibrous or porous material, as cotton waste, which is fitted in the journal box, below, and in contact with, the axle journal which rotates therein. The object of my invention is to prevent the seriously objectionable heating of the journal which frequently occurs in service; the leakage of oil from the journal box; and the displacement of the packing, by effecting a constant circulation of air through the journal boxduring the running periods of the vehicle on which it is fitted; preventing the access of.

oil to the joint between the box and its lid; and holding the fibrous packing in normal relation to the journal. 7

The improvement claimed is hereinafter fully set forth. I I

In the accompanying drawings: Figure 1 is a vertical longitudinal central section through a journal box, illustrating an embodiment of my invention; Fig. 2, a horizontal section through the same, on the line a a of Fig. 1; Fig. 3, a view, partly in front elevation and partly in vertical transverse section, on the line b b of Fig. 1; and Fig. 4, a similar section, illustrating a structural modification.

In the practice of my invention, referring descriptively to ,the specific embodiment thereof in connection with a journal box, 1, of the Master Car Builders type, which is herein exemplified, the 'ournal box is, as heretofore, fitted with a inged lid, 2, closing an opening in its front for the insertion and removal ofpacking. The front end of the journal box is provided, adjacent to the opening therein, with an inwardly and downwardly projecting deflecting plate, 3, having lateral ribs or flanges, 3", pro ecting from its inner face, formed on, or fixed to, the lid, with its bottom about in line horizontally with, or somewhat below, the axlal line of the journal, 4. I have found that, in practice, oil is thrown up from the packing, by centrifugal force, from the per1phery of the end collar, 4*, of the axle, and tends to follow down the inside of the lid, and leak out'through the opening covered by the lid. It has been shown, by tests, that by the application of the deflecting plate, the oil which is thrown toward the top of the box, is caused to pass down on the inside of the deflecting plate and drip off into the box, without leakage therefrom, this action being facilitated by the side flanges of the plate, which prevent the oil from running off its sides and therefrom to the sides of the lid. A material saving of oil, which would otherwise be wasted, is accordingly effected. Y

A longitudinally extending air channel, 5, which is open at both ends, is formed on, or fixed to, the outer side of the box lid, 2, said channel communicating with an adjoining closed ended suction chamber, 5*,

through an opening, 5 the suction chamber communicating, in turn, with the interior of the journal box, through an opening, 5, in the lid, located a short distance below the upper end of the deflecting plate, 3. In the movement of the vehicle on which the j'ournal box is installed, the current of air passing through the channel, 5, acts to draw air out of the suction chamber and the communicating interior of the journal box, the air withdrawn being replaced by fresh air leaking into the inner end of the box. This circulation of cool air through the journal box prevents the heating of the air therein, which would be liable to occur if the air was permitted to remain quiescent therein, as in ordinary practice, and correspondingly reduces the liability to heating of the journal.

In order to insure the fibrous packing of the journal box being retained longitudinally in normal positiontherein, a plurality of upwardly projecting teeth or packing retainers, 6, is formed on the inside of the bottom wall of the journal box, said teeth being preferably, as shown, disposed in two longitudinal rows, and being curved or inclined toward the inner end of the box, so as not to interfere with the free insertion of the packing, and to resist its accidental and undesired movement, from its normal position ard practice, nor involve the use of any I claim as my invention and desire to se-.

cure b Letters Patent:

1. T e combination ofa journal boxhaving an opening in its outer end; a lid, normally closing said opening; and an inwardly and downwardly projecting deflecting plate, fixed on the inner side of said lid,

2. The combination of a journalbox having an opening in its outer end; a lid, normally closing said opening; an inwardly and downwardly projecting deflector plate, fixed on the inner side of said lid; and lateral flanges, projecting upwardly from said deflecting plate.

3. The combination of a journal box provided with a lid, having a ventilating opening, of a deflector plate fixed on the inside of said lid, above said opening and adapted to extend below the same, providing a shieldtherefor, to prevent the splashing of oil and dirti'into said opening.

oil from being thrown out from around the lid during the active use of the journal box. 5. The combination of a journal box, had lng' an opening in its outerend, a lid, normally closing said opening, av ventilating passage-way carried by said lid, an aperture in said lid connecting the said passage-way with the inside of the journal box, a downwardly projecting deflector plate fixedon' the inner sideof the lid above said aperture and extending below said aperture, providing a shield therefor, to prevent the splashing of oil and dirt into said ventilating passage-way.
