DUST-GUARD FOR JOURNAL-BOXES.

Specification of Letters Patent.

Patented Jan. 8, 1918.

Application filed February 26, 1917. Serial No. 150,917.

To all whom it may concern:

Be it known that I, HARRY C. MCCARTY, a citizen of the United States, residing in .Villiamsport, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Dust-Guards for Journal-Boxes, of which the following is a specification.

This invention relates to journal-boxes, and especially to journal-boxes used upon railroads, or mine or like cars, in which the wheels are fixed to the axles, and the axles revolve in the journal-boxes; and comprises a peculiar construction of the journal-box, whereby a dust-guard is provided, of a new and improved form which encircles the axle on its inner-end; and while preventing entrance of dust or dirt to the axle at the same time assists by capillary-attraction in feeding oil or other suitable lubricant thereto.

Such invention is a modification of, and an improvement on the devices shown, described and claimed in my two Letters Patcut for a dust-guard, No. 711,6i1, granted October 21, 1902; and Letters Patent No. 743,653 for a journal-box, granted November 10, 1903.

I have found that by experimental use that a better dustguard, having more etlicient means of lubrication, than those now used, which is also of longer life, is formed by having such guard stiffened in some manner at its outer edges. and that its insertion and removal are facilitated by such stiffening; and I have also found that the placing in position is facilitated by having a journal-box made with a pocket for receiving such dust-guard open at the top whereby such guard can be easily and quickly slipped into position before the placing of the journal-hox upon the axle.

My said invention is fully shown, described and claimed in the following specification of which the accompanying drawing forms a part; wherein similar letters or numerals of reference designate like or equivalent parts throughout the several views, and in which:

Figure 1, is a view in longitudinal central vertical section of my improved iournal-box and dust-guard, with the car-axle and dustguard in position;

Fig. 2, is a view of such dust-guard and axle in vertical section, taken on the line 2-2 of Fig. 1, looking toward the right in the direction of the arrow;

Fig. 3, is a view in detail in perspective, and also central v rtical section on the line 3-3 of Fig. 2;

Fig. 4:, is a view in detail of a portion of the axle, with the contacting portion of the dust-guard shown in section mounted thereon.

Referring to the drawing;

The reference letter A, designates a car journal-box, of any suitable form, usually that shown, having the front opening, for

purposes of introducing lubricatory mate-' forms no part of my invention, 1 have not deemed it essential to show or indicate such part of the construction.

At the inner end of such journal-box. is formed the box 12 open at the top, having the inner-wall i3, and the outer-wall 14; and the side-walls 15 and bottom 16, which pocket is usually of the rectangular form clearly indicated in Fig. 1.

The reference letter C indicates the axle, and C the axle journal-bearing, on which is superposed, in the well-known manner, the usual segmental inner faced journal-bearing plate D, held in position by the securingwedge or kevpiece E, secured in place when in position by the transverse locking-pin or projection-key F, of the ordinary wellknown form.

My improved dust-guard. used with this particular form of journal-box, comprises a rectangular dust-guard body G, usually and preferably formed of two or more superposed sheets of suitable flexible woven wicklike material, such as cotton-duck, etc., which will feed the lubricant-oil from the bottom of the journal-box to the center of said guard G, and to the axle.

As shown in the drawing, such dust-guard G, is formed of two or more plies of canvas, or other suitable wick-like material. having the central opening 17, prevented from spreading adjacent to such opening by the circular line of stitches 18. surrounding such opening, and secured to the sides and bottom of such flexible fabric dust-guard. is an outer rectangular stillening frame 19, se-

cured thereto in any desired manner, which,

when in position, prevents entrance-of dust of fabric as clearly indicated in'the drawings; and being secured at the corners by double-pronged tacks or binder staples 20, and the plies of fabric being secured thereto by binder staples 21, or in any other desired manner.

Such frame 19 may be made of any suitable rigid solid material, but for cheapness I have found soft wood tobe good and efficient for such use.

In assembling, the dust-guard G is placed in position in the dust-guard-pocket 12, by slipping the same in from the top; the journal-box A is then'slippeol over the end of the axle, and bolted in position upon the truckframe (not shown). The journalbearing inner segmental shaped plate D, is then slipped in position through the opening normally covered by the journal-box lid 13, the key-piece E, in like manner inserted in place so as to hold such journal-bearing plate D in position upon the bearing surface C of the axle, andjs'ecure'd in place by the insertion of the transverse locking pin or projection key F. And when in such position the central orifice 17 of the dust-guard G, being slightly smaller in diameter than the inserted axle Q, the plies thereof will be slightly spread apart at the bottom as clearly indicated at 22 of Figs. 1 and 4; whereby the oil contained in the bottom 23, of the journal box A, will be more liberally fed and distributed to the axle.

It is evident that many changes and modifications in the construction, combination and arrangement of the several parts of my device herein shown, described and claimed, may be made, without departing from the scope of my invention, but I do not intend to limit myself to the exact construction shown and described. 1 I

I' claim:

1. A dust guard for revoluble vehicle axles and the like'compo'sed of two or more plies offlexible wicklike material having a central orifice to receive the axle, of a slightly smaller diameter than the axle, a"

circular line of stitching securing the plies together adjacent the central orifice, and a rectangular frame of wedge shaped form in cross section, inserted in and secured to the flexible wicklike material, having a central orifice to receive the axle, of a smaller diam eter than the axle, a circular line of stitching securing the plies together adjacent a central orifice, a rigid frame of wedge shaped form in cross section inserted in and secured to the fabric plies of the dust guard between the same at the outer bounding edges, with the thin end of such wedge shaped sections facing inwardly, and a journal box having a dust guard chamber at the rear, with a central orifice for the passage of the axle, open at the top for the reception of the dust guard.

3. A dust guard for revoluble axles and the like comprising a plurality of plies, of flexible wicklike material having an opening to receive the axle, and a rigid frame of wedge shaped form in cross section, inserted and secured to the fabric plies of the dust guard between the same at the outer bounding edges, with the thin end of such wedge shaped section facing inwardly;

4. A dust guard for revoluble, axles and the like, comprising a plurality of plies of wicklike material having an opening to receive the axle, and a rigid frame fitted between and secured to the outer bounding edges of the plies, of wicklike material.

5. A dust guard for revoluble axles and the like comprising a plurality of plies of wicklike material having an opening to receive the axle, and rigid membersinserted between and secured to the plies of wicklike material at the outer bounding edges thereof. 6. A dust guard for revoluble axles and the like comprising two or more plies of" flexible material having'an opening to receive the axle, and rigid members inserted between and secured to plies of flexible ma-" terial. adjacent the outer bounding edges:

thereof. I

7 A dust guard for revoluble axles and the like comprising two or more plies of.

flexible material having an opening to re ceive the axle and rigid members of wedge shaped form in cross section, inserted between and secured to plies of flexible material at the outer bounding edges thereof, the thin edge of such wedge shaped members" facing inwardly.
