LACEY Y. WILLIAMS, TOLEDO, OH IO,

I rust-GUA i To all (whom it may concern y Be it known that I, Lil-on: Y. WILLIAMS, acitizen of the United States, residingat Toledo, in the county ofLucas and State have invented certain new and useful Improvements "in Dust-Guards,

' which the following is a specification.

The object of the invention is the production of a metallic dust guard for car journal 1 boxes \vhic shall be'eflectivein excluding dust and dirt from the rear of the box, du-

- rable in service, simple inconstruction, and" Y. which can be manufactured cheaply and having a flange bounding an opening and adapted to surround a journal and a flange sold'at a relatively low price. 1

The invention consists in stamping to the required shapes from thin metal, preferably sheet steel, two complemental parts, each at substantially right angles thereto, one of saidlatter flanges being preferably slightly dishcd,and uniting said parts by inserting one flange bounding thev opening withinthe other similar flange and bending the edge of the flange or upsetting the same to hold the parts together.

It in her consists in certain novelties of construe ion in shape and in the combination of parts as herein set forth and claimed.

The accompanying drawing" illustrates an example of the emb'odilnent of the'invention constructed and the parts, combined according to the best mode of procedure I have so far devised for the purpose. Figure 1 shows a journal box'in vertical section, a journal in elevation, andzone of my improved dust guards in the chamber and also in section.

l igs 3 is an edge view of Fig. 2. a Fig. 4 is a section'on line 4 4 of Fig. l ig. 5 is a section on line 55 0f Fig. 2. The guard is comprised of two complenicntal parts A, B, each of which may be and preferably is fashioned by cutting to shape a resilient metal blank, cutting a circular opening therein, bending; the edge ofthc metal defining the opening outwardly to form a flange C at right angles to the plane of the lillank and turning the entire or part of the outer edge of the blank slightly,as at D i n frictional contact with the surfaces of the to contact with b'ox chamber under pressure and thus form I of the flanges so the edge of the metal will easily move Specification of Letters Patent Patented A'pr, 24 1911 et iu auon filed. ma 17, 1916; Serial no. cams.

of be blank as above set the other andfiturnmg the edge of one flange C, within the flange C of C at F so as'to securely unite them. This latter operation may" also be effected by means of a press. I y In the completed guard the fiangesAand I, B are spaced apart, the curved edges D extendin toward each other, as shown.

The anges C, C may be of about the'width of the box chambenthat is approximately seven eighths of an inchwide when both flanges .A, B are at right angles tothe flanges C, C. However tor cause both flanges A, B the inner surfaces of the tight joints one of theflanges, ,as B, may be slightly dished to form with flange C an angle slightly greater than a right angle, as shown by the, figures of the drawing When one of the fiangesis dished the flanges 'C, C may be slightly of less width than seven eighths of an inch as is obvious.

The exterior outline of the guard is determined by the shape of the chamber within which the guard is to be inserted, and may vary accordingly.

I designatesa journalbox of common construction J the-.dustguard chamber; and K an axle journal.

Upon reference to Fig. 1 it will be seen that a flange C is in frictional contact with the dust guard bearing of the journal, one A in contact with the inner surface of the metal bounding the chamber and closing the opening G, and that the edge of the other dished flange B is in contact with the opposite surface closing the opening H, both flanges being pressed against opposite surfaces bythe resilience of the metal so that any foreign substance, such through the opening in the guard in the ten the two together; one of said outwardly usual manner. extended flanges being dished relative tothe What I claim is: circular flanges.
