DUST GUARD.

LAGEY Y.'w1nI.In1vis,- onron'nn 'omd 4 DUST-GUARD.
To aZZ'tiJh-Om it may concern Be it known that L'Lncny Y. W LLIAMS,
a citizen of the United States, residing at fro Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Dust-Guards, of whichthe following is a specification.
The object of the invention is the provision of a guard especially adaptedfor 1nsertion within the chamber at the rear end,
of a car journal box and which shall frictionally engage one of the vertical surfaces,
.' preferably the front surface, bounding the chamber under all conditions of service, and thus prevent dust and dirt or other foreign substance or substances passing to the interior of the box and to the journal bearing.
The invention consists in a dust guard having at one of its vertical surfaces, and preferably both at the top and bottom thereof, spring means for forcing the opposite vertical surface against the vertical surface bounding the box chamber.
Finally, it consists in certain novelties of construction and combinations of parts as hereinafter set forth and claimed.
The accompanying drawing illustrates an example of the physical embodiment of the invention-constructed according to the best mode of procedure I have so far devised for the purpose.
Figure 1 is a vertical section of a journal box with a guard within the chamber thereof, said guard having at one of its surfaces means for forcing the opposite surface into frictional contact with one of the vertical surfaces bounding the chamber. Fig. 2 is an enlarged plan view of the guard removed from the box chamber, part of one of the retaining plates being removed at the bottom thereof to show the relative locations of certain parts. Fig. 3 isa section on line acm of Fig. 2.
The particular guard illustrated is comprised of two complemental L-shaped' sections A A having edges with curved surfaces B B which, when the sections are assembled, constitute a circular opening for the reception of the journal. The top and bottom edges of the guard are recessed at O C by removing or cutting away part of the material of the sections, and two semicircular seats D D and one central rectangular seat E may be provided for springs and 5 a roller.
The letter F designates the springs which I i Specificationof Letterslatent.
-. Application filed April 29,1912.
Serial No. 693,822 l are conical coiledsprings in this instance,
f, PatentedNov.
each having an eye (I, and H is the roller of I anysuitable material having a central open 6O ing within which islocated a small rodlor bar I, the ends of which rod or bar are se'-- curedwithinthe eyes G of the springs, as shown; To hold the springs'and roller in their proper relative-positions within a,re-' cess Ctwo plates are secured to the guard.
The back plate J has an opening K through which-the roller pro ectsand a flange, L
overlapping the end of the guard. The
front plate M serves as a bearing for the springs. These plates are fastened to the guard in any way desired, as by brads N,
screws or otherwise. The journal box 0 I has a chamber P with front and rear vertical surfaces R and S, respectively.
When the guard is inserted in the chamber the spring pressed rollers at the top and bottom of the guard projecting through the openings K in the back plates will bear against the surface S bounding the chamber, and the springs will force the opposite or plain surface of the guard into frictional contact with the vertical surface R of the chamber and thus prevent the passage of any dust or dirt to the interior of the box. The rollers facilitate the insertion of the guard into the chamber and also allow the separation of the two L-shaped sections and their readjustment when the journal is inserted into the box.
, I have illustrated the invention embodied in connection with a dust guard having two L-shaped sections, but it may be embodied in connection with any of the other known forms of dust guards for performing the requisite functions of holding one surface of the guard in frictional contact with one of the vertical surfaces bounding the chamber and excluding foreign substances from the interior of the journal box.
What I claim is:
,1. The combination in a dust guard, of sections, each section having an edge with a curved surface, which edges, when the sections are united, form a circular opening adapted to engage a journal, also each section having at another edge a closed recess.
with an opening thereto, bearing elements each partly located in a recess and partly projecting through the opening to said recess, and a spring within each inclosed recess pressing the bearing element outwardly;
the said recesses for the springs and bearing elements "being 'locatedat opposite sides of the circular opening through the guard." 2. A dust guard havinganopening for a journal, and means consisting of rollers and springs, one roller being located eachside ofthe opening, for forcing the guard length- W'iseof the journal and' against one ofthe vertical surfaces bounding the chamber of the journal box. 7
3. A dust guard; having :an- Opening and recesses at opposite sides of said opening-, and aroller within; each recess -with its; edge; proj ecting beyond the surface of the gnard for the purpose set forth, I v v -V 4. A-dHSt guard having an opening and recesses at opposite sides *of; said opening,=f plates each with; an opening; therein secured to the guard,--a roller within each reces'sandprojecting through the opening in a plate, and springs for projecting the recesses at opposite sides of the opening plates with openings inclosing the recesses, a roller in each recess and projectingthrough an' opening in'a p late, a rod or bar passed through an openlng in each roller, and
springs Within each recess connected to'the' rod or bar passed-through the roller.
