Application filed July 22,

This invention relates to railwa journal box protectors or dust guards. T ese prg; .around a railway car axle adjacent the journal portion and work in slots formed in therear end of the journal box. The are necessarily made movable relatlve to t e ournal box and are intended to keep dirt and grit out of the journal.

Railway journal boxes, as heretofore constructed, have generally comprised a block of wood cut to the right shape and bored to Wood has been employed because it will not bind on the axle despite the heat generated or desplte madequate lubrication. Woodis also used because it is light and therefore does not tend to wear a lar e hole as quickl as would a protector mafe of heavy meta It will be understood, of course, that the weight of the protector is carried by the axle.-

The wooden protectors have been open to They crack and split, and even though made of high quality wood, they wear large at the hole and permit dlrt and grit to enter the journal.

I provide a journal box protector which is made of a light weight metal, plreferably aluminum. This does away wit all the splitting and cracking troubles experienced with wooden protectors. At the same time the tendency of the hole to wear large is, reduced-first, because the protector is very light in weight, and second, because I secure a better bearing between the rotector and the axle than has heretofore een obtained' r b1 1 f fib I re era em 0 a rin o rous map y car ied by th e rotector and extends around the car axle. his ring may be made of felt or the like, thus securing suflicient flexibility to maintain a relatively tight joint despite any slight wear which may occur. The felt ring hes close against the axle at all times and thus prevents dirt from entering the journal box.

The protector is preferably made hollow so as to receive a lubricant. This lubricant is not intended to be used in normal car operation, but is for emergency urposes only. The hollow space is connected b a passage extending toward the journal, t is being normally sealed off by a suita terial, such as wax,

In the accompanying drawings which illustrate the resent preferred embodiment of my invention,-

The protector or dust guard comprises a body portion 7, a felt ring 8 and a retaining r1ng 9. The body portion 7 is made of aluminum and is cored out as indicated at 10 to form an annular flange and a flan at the edge ofthe body surrounding t e first flange, which flanges are connected to each other at spaced intervals by short webs, so that it will be as light as possible and still have the desired structural strength.

The felt ring 8 comprises a flat flange-like portion 11 lying in a recess formed in the body 7, and a cylindrical portion 12 which lies along and closely engages the car axle 2 The portion 12 is inte al with the port1on 11, and by reason 0 this construction the natural spring of the felt causes it to closely embrace the axle at all times.

he ring 8 is held in place by the ring 9 which in turn is secured by screws 13.

The ring 9 is hollowed at its top portion, as indicated at 14, and a passage 15' is ro vided in the body portion 7 so that the 01- low portion 14 may be filled with lubricant.

he ring 9 makes a sufficiently close fit with the other parts of the rotector that the lubricant will be retained vided with openings 15 hollow These 0 section, and the protector extending from the portion 14 toward the ournal 3.
