' This invention relates to journal boxes, and its general object is to provide a journal bearing protector that prevents packing, waste or foreign matter from passing be- 5 tween the axle and bearing, but in no'event does it interfere with the passage of oil about the axle or with the proper operation of the parts of the journal box under all working conditions. I

A further object of the invention is to provide a protector of the character set forth, that is applicable to the types of journal boxes now generally employed on all railroad cars. without changeto the boxes or any parts thereof. 7

Another object of the invention is to provide a journal box protector that can .be applied in operative position or removed therefrom in messy and expeditious manner with very little effort, and is simple in construc:

tion, inexpensive to manufacture and ellicient in operation and service.-

This invention also consists'in certain other features of construction and in the combina- 85 tion and arrangement of the several parts,

to be hereinafter fully described, illustrated imthe-accompanying drawin and specifically Pointed out in the appen ed claims.

11 describing my invention in detail, refer- 80 once will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views,- and in which; 1

. The protector which forms the subject matter of the present invention is provided with a' body 1 which is preferably formed from sheet metal and has its upper portion.

formed to follow the shape of the top of the journal bearing Cand. this upper portion 1s adapted to be received between the journal bearing and journal. wedge as best shown in Figure 3 of the drawinga' ormedwith the lower edge of thecon co verging walls of the upper portion, are the side walls 2v of the protector which are pro-' vided with substantially rectangular shaped openings 3 to accommodate projections extending laterally from the journal'bearing as best shown in Figures 1 and 2 of the drawings. These projections prevent the longi-' tudinal movement'of the protector and coopcrating therewith is a tongueiextending fromi approximately midway the ends of the forward edge of the upper portion as shown in" Figure 4, and this tongue 4 engages the for- .ward end of the journal bearing, while the rearward edge of the upper portion of the protector is disposed in contacting engagel ment with the flange formed on the inner end P of the journal bearing asshown in Figure 1.

By this arrangement; it will be obvious'that the protector is' held against longitudinal movement. and due to its transverse shape so I which conforms to the shape-of the confronting faces of the bearing and wedge, transverse movement of the protector will be prevented, with the result it is practically impossible for the protector to be casually moved from its operative position as shown. Formed with the side walls at their lower edges .is an inwardly inclined flange 5. These flanges 5 are disposed in conver g relation with respect to each other and veseeured 9 thereto by rivets 6 mother suitable securing means non-metallic strips 7-. which have formed therewith adjacent their edges: as

well as midway the ends thereof projections 8 having-rounded corners 9 so as to revent the protector from catching on the ax collar E when being dis sad or removed with re spect to the journa box.

Theprojections 8 are arra ed incontactin'g engagement with the a e and are debearing and wedge of signed to prevent the passage of waste, packing,or foreign matter about the axle with the result, this material cannot accumulate between'thebearing and axle. Notwithstand- 5 ing the fact that my protector prevents the passage of the material as above set forth, it will not interfere with the-pro er lubrication of the journal box as it will e apparent that due to the space between the projec- 9 tions 8, oil can freely pass about the axle.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

" I desire it to be understood that I'may make changes in the construction and in the combination and arrangement of; the several parts, provided that such changes fall within the scope of the appended claims,

1. The combination with a journal box, of a protector for the journal bearing thereof comprising a body formed from sheet metal and including an upper portion shaped to follow the confrontin faces of the journal said box, side walls included in said body and being disposed in parallelism with respect to each other, a

flange-for each side-wall and the flanges being disposed in converging relation, non-metallic strips secured to saidflanges, and projections formed with said strips andbeing adapted to be disposed in contacting engagement wit-h the axle in the journal box.
