DUST-GUARD FOR JOURNAL-BOXES.

Specification of Letters Patent.

Application filed August 29, 1917. Serial No. 188,698.

To all whom it may concern:

Be it known that I, HARRY C. McCAR'rY, a citizen of the United States, residing in VVilliamsport, 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, street railway or mine or like cars, in which the wheels are fixed to the axles; and axles revoluble in journaLboxes. The: present invention comprises a new and im proved form of dust-guard for encircling. the axle for preventing the entrance of dust or dirt, at the same time assisting, by capillary-attraction, the feeding of oil or other lubricant to the journal. is

This invention is a modification of, and an improvement on the devices shown, de scribed; and" claimed in my two Letters Patent for a dust-guard, No, 711,641, granted October 21, 1902; and Letters, Patent No. 743,653, for a journal-box, granted I November 10,1903; and my application,

Serial No. 150,917, filed February 26, 1917, I; have found, by experience that a very eiiicient and durable dustguard and a very efficient means of lubricat on is formedlby having such guard stiffened at its outer edges by means of folded pieces of fabric; and that its insertion and removal are facilitated by such stiflening, and I have also found that such a dust-guard is easily placed in position in the pocket provided in the journal-box for receiving such dust-guard; and that the guard is snugly received in said pocket. L y 1 i My said invention may be very cheaply constructed and is fully shown, described and claimed in the following specification, of which the accompanying drawing forms a part; wherein similar letters and numerals of reference designate like or equivalent parts throughout the several views and in which y a Figure l is aview in longitudinal central vertical section of my improved journalbox and dust-guard, with the oar-axle and dust-guard in position; I

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; I i

Fig :3 is a v w in deta l inipe sp st v and also central vertical section on the line as of Fig. 2; r I

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 more particularly to the drawmg: i

A designates a car journal-box which may be that shown, or may be the Master Car Builders journal-box having the front open-v ing, for introducing lubricating-material, closed in the well-known manner by j ourna1- box lid B, pivoted at 10, and provided with the spring 11, for maintaining the same in the open position for cleaning, or introducing new lubricant. Such journal-box is, of course, provided with suitable means for securing the same rigidly to the truck-frame; but as this forms no part of my invention, I have not deemed it essential to show or indicate this part of the construction. i

a At the inner end of such journal-box, is formed the pocket 12' open atthe top, having the inner-Wall 13, and the outer-wall 14;

and the side-walls 15 and bottom 16; which pocket is usually of the rectangular form clearlyindicated in Fig. 1. g

posed in the well-known manner, the usual bearing-plate D. 7

My improved dust-guard, used with this particular form of j ournal-box, comprises a rectangular dust-guard body G, usually and preferably formed of two superposed sheets of suitable flexible woven wick-like material, such as cotton-duck, etc., which will capil larily feed the lubricating oil from the bot tom of the journal-box, to the center of said guard G, and to the axle. As shown in the drawing, such dustguard G, is formed of three or more plies of canvas or other suitable wick-like material, having the central opening 1?, prevented from spreading adjacent to such opening by the circular line of stitches 18, surrounding such opening; and secured to one face of the sidesv and bottom and top of such one or more ply flexible fabric dust guard, is an outer rectangular Lstiflening frame '19 composed of suitable wick-like fabric, for instance, the same fabric as the itself, as atgo, whereby the frame comprises four plies as shown inFigs. l, 3, and i. The plies of the frame are stitched together by the lines of stitches and then the Whole is stitched to the body of the dustguard by lines of stitches 26 passing entirely through the one or more plies of the dustguard body and two or more plies of the f ame.

The main body portion of the dust-guard G is strengthened by the insertion, between the plies thereof, of a strengthening ply extending to the outer edge of the dustguard and terminating at its inner edge near the line of stitches 1S.

When the guard is in position the frame forms a somewhat yielding combined packing and stiffening which prevents entrance of dust through the open top of the pocket.

In assembling, the dustguard placed in position in the dust-guard pocket 12, by slipping the same in from the top. When in such position the central orifice 1'? of the dust-guard G, being slightly smaller in diameter than the inserted axle C, the one or more plies thereof, Will be slightly spread apart at the bottom as clearly indicated at 26 of F l and at; whereby the ingress of dust and dirt is prevented and the feeding of the oil contained in the bottom 2'7, of the journal-box A will be more liberally 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.

I claim as my invention: 7
