To all whom, it may concern.-

Be it known that I, JosEPH A. HALEY, a citizen of the United States of America, residing at Fort \Vayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Dust- Guards for Journal-Boxes or Lubricating- Receptacles; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in dust-guards for j ournal-boxes or lubricatingreceptacles, and pertains more especially to an improved dust-guard having a body portion composed of two sections movable upwardly and downwardly, respectively, from within the journal box without necessitating the removal of the box from the axle.

This invention consists in certain meritorious features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation, in central longitudinal section, of a journal-box provided with my improved dust-guard which is contained within the in ner end of the box and extends around the axle which extends into the box. Fig. 2 is a vertical section on line 2 2, Fig. 1, looking in the direction indicated by the arrow. Fig. 3 is a top planin section on line 3 3, Fig. 2(

Fig. 8 is a top plan in section on line 8 8, Fig. 2. Fig. 9 is a top plan in section on line 9 9, Fig. 4. Figs. 3, 4, 5, 6, 7, 8, and 9 are drawn on a larger scale than Figs. 1 and 2.

Referring to Figs. 1, 2, 3, and 4 of the drawings, a indicates a journal-box, and b an axle which extends into the box in the usual manner. The box is provided within its inner end with a quadrangular chamber 0, which extends around the axle and is occupied by a correspondingly-shaped dustguard, which has a body portion comprising, preferably, an upper section D and a lower section (Z and is provided 'with a centrally-located axle-accommodating circular opening 10, formed one half in the lower portion of the upper section D and the other half in the upper portion of the lower section (1. The sections D and (1 therefore embrace the upper portion and lower portion, respectively, of the axle b and meet each other at their adjacent ends at the sides of the axle centrally between the top and bottom of the axle. The sections D and (Z are preferably each composed of a sheet-metal plate. The forward or outer side wall 12 of the chamber 0 is smooth and the forward or outer side or face of the body portion (sections D and d) of the dust-guard is correspondingly smooth, so that whenthe said body portion is held against the said wall a dusttight joint is formed between the said wall and the body portion of the dust-guard. The chamber 0 is open at the top to accommodate the introduction thereinto of the upper section D of the body portion of the dust-guard. The chamber 0 is open at the bottom of the j ournal-box to accommodate the introduction into the said chamber of the lower section (1 of the body portion of the dust-guard. It will be observed, therefore, that the body por tion of the dust-guard is assembled relative to the axle by inserting the upper section and lower section, respectively, of the said body portion at the upper end and lower end,respec tively, of the chamber 0. The two sections D and cl when they have been assembled rela tive to the axle are detachably secured together. The means preferably employed for separably connecting the sections D and (Z together comprises two upright metal bars G, arranged next to the rear side of the body portion of the dust-guard at opposite sides, respectively, of the axle-accommodating opening 10. The two bars G are arranged vertically and extend through correspondingly-arranged holes 13, (see Fig. 3,) formed in and extending through horizontally-arranged lugs or flanges 14, with which the upper dust-guard section D is provided at its upper end, and cotter-pins f extend through the said bars next above the lugs or flanges 14.

The section D is provided a suitable distance above its lower end and adjacent to TOO each bar G with two lugs 16, which project from the said section D at opposite side edges, respectively, of the bar and overlap that side of the said bar which faces the rear wall 15 of the chamber c that is, two lugs 16 are formed upon the section D adjacent each bar G and project from the said section at one side of the bar and form guides for the bar at opposite side edges, respectively, of the bar and project toward each other at and overlap I the section D at one side of the lug through the opposite side of the bar. The said lugs are instrumental in guiding the said bar during the assemblage of the parts and prevent displacement of the said bar toward the rear side wall 15 of the chamber 0.

Each bar G is provided near its lower end with two recesses g, formed in opposite side edges, respectively, of the bar, which recesses are engaged (see Figs. 2, 4, and 9) by laterallyfiexible lugs 17, formed in and projecting rearwardly from the lower section cl of the body portion of the dust-guard, which lugs also overlap that side of the said bar which faces the rear side wall 15 of the chamber c that is, two lugs 17 are formed upon the section d adjacent each bar G and project from the saidsection at one side of the bar and snugly engage recesses g and g, formed in opposite side edges, respectively, ofthebar and project toward each other at and overlap the opposite side of the bar.

By the construction and assemblage of parts hereinbefore described it will be observed that the bars G are suspended and de tachable from the upper end of the upper section D of the body portion of the dustguard and detachably secured at their lower ends to the lower section (1 of the said body portion. The two sections D and d are therefore detachably connected together and obviously are free to be separated from each other by withdrawing the cotter-pins f from the bars G.

The sections D and d are each provided with two springs 18, which project from opposite side edges, respectively, of the respective sections and curve toward and into contact with the rear wall 15 of the chamber 0. The springs 18 are held under tension by the said wall 15 and act to retain the connected sections of the body portion of the dust-guard in engagement with the wall 12. The springs 18* operate, therefore, to maintain the dustguard in contact with the forward wall 12 of the chamber 0. The opposing surfaces of the body portion of the dust-guard and the Wall 12 are smooth, and consequently the holding of the sections D and d in contact with the said wall insures the maintenance of a dusttight joint between the said wall and the bodyportion of the dust-guard. The upper section D of the body portion of the dustguard is provided at its rear side with an annular metal section or bearing-piece K, extending circumferentially of the upper pore tion of'the opening 10 and aflording bearing tothe upper portion of the axle b. The bearing-piece K is detachably secured to the section D, and preferably the said member K is provided at the top and centrally with an upwardly-projecting lug 20, which is provided with a slot or recess 22, engaged, as shown in Figs. 1, 2,and 3, by a flexlble lip 23, formed on the'section D. The lip 23 projects from the recess 22 of the said lug and overlaps the opposite side of the said lug.

The bearing-piece K (see Figs. 2, 7, and 8) is provided also with two laterally and outwardly projecting lugs 25, arranged at opposite ends, respectively, of the said bearingpiece. Each lug 25 is provided centrally with a slot or recess 26, which is engaged by a laterally-flexible lip 27, formed on the section D. The lip 27 projects from the section D at one side of the lug 25 of the bearing-piece K through the recess 26 of the said lug and overlaps the opposite side of the said lug. The bearing-piece K can therefore be readily detached by bending the lugs 25 to render the said bearing-piece free to be removed.

An annular bearing-affording jaw L (see Figs. 1, 2, and 4) embraces the lower portion of the axle b and is shiftable vertically. The jaw L extends circumferentially of the lower portion of the axle-accommodating opening 10 and overlaps the rear side of the section (1 along the said opening. The jaw L is provided with two vertical side edges Z, formed at the opposite ends, respectively, of the jaw, which edges are overlapped by guide-forniing lugs 28, formed on and projecting from the lower section (1 of the body portion of the dust-guard. The lugs 28 and edges Z are instrumental in guiding the jaw L, which is held in contact with the axle'by a suitablyapplied spiral spring Q, arranged centrally between the ends of and below the jaw and confined between the jaw and a lug 30, formed on and projecting rearwardly from the lower end of the section d. It will be observed, therefore, that the spring Q operates not only to retain the jaw L in contact with the axle, but acts also to depress the dust-guard and take up wear between the bearing-piece K and the axle.
