JOURNAL-BOX LUBRICANT DEVICE.

vices, of whichthe following is a speciti-- cation.

My invention relates to an improvement in the class of lubricant-devices forthe journals of car-wheels, wherein the lubricant confined in the box is in a solid form, as a cake, spring-supported in the journal-box to bearagrainst the journal from underneath the latter through the medium of a perforate plate interposed between the cake of lubricant and the journal; and it consists in the novel features of construction hereinafter described and claimed.

Inthe accompanying drawing, Figure 1 is a view in longitudinal sectional elevation of a journal-box provided with my improvement, Fig. 2 is a section on line 2, Fig. 1, and Fig. 3 is a broken section on line 3, Fig. 2.

The journal-box 3 illustrated is of the ordinary kind for housing a journal 4 and In the side-walls of the box are provided, near each of its ends and opposite each other, parallel

vertical slots

6 and 7, forming pairs; and over each slot extends laterally from the top of the box a lug or hanger'S from which to suspend a coiled spr'inc 9.

Bars

10 and 11 extend transversely across the interior of the box respectively through the pairs of

slots

6, 7 and are suspended at their projecting ends by the 1 springs to Work underneath the journal. A

holder 12, or dish, adapted to carry a cake 13 of suitable lubricant, is supported at itsend-portions on the bars 10, 11: and seating on the upper longitudinally-concave surface of the cake is a laterally-flanged convexoconcave plate 14' conforming on its under side to the surface of the cake 13 upon which it bears, and on its upper side to the arc of the lower section of the journal. The depending flanges 15 of the plate-lap the sides of the holder to protect the lubricantfrom foreign matter that may enter the box through the slots, which are provided with vcrl belly-movable gates 16 that rest at their ]on'er ends on the bars to yield upwardly as the springs raise the latter to cause the plate to bear against the journal notwithstanding constant diminution of tne thickness of the lubricant-cake by use. The plate has formed in it, as by punching from the convex side,

numerous perforations 17, from which extend burs or, projections 18, which may be formed by the punching" operation. to contact with the journal-surfaces. These projections are an important feature of my improvement, inasmuch as they intercept in the spaces between them the lubricant drawn through the perforations by the frictional heating and resultant softening of, and the suction action exerted upon the lubricant by the rotating journal. The lubricant thus lodges in the spaces between the projections and is therebv presented to the journal-surface in a continuous supply, since the springs maintain the cake, until used up, always against the under surface of the perforated plate and the plate-against the journal-surface; and the projections oppose the tendency of the rapidly-rotating journal to wipe the lubricant from the adjacent surface of the plate off into the journal-box, which would result unless the shedding from the platc-surf: 1ce in that manner of the lubricant. and the ensuing waste thereof, were thus prevented.

lVhat I claiin as new and desire to secure by Letters Patentis- 1. In combination, a journal-box having slots in its sides, and a lubricant-device comprising bars extending transversely through the box below the journal therein and projecting through said slots, springs suspended on the box to extend at the outer sides thereo'f and connected with the bars to carry them at their projecting ends, a lubricant-holder supported within the box on said bars, and a perforated plate interposed between the holder and journal, for the purpose set forth.

2. in combination, a journal-box having porting said holder below the journal and working in the journahbox slots, and a pet'- forated plate surmounting the holder and provided with projections on its upper surt'ace hearing against the journal'and forming lubricant-confining spaces, for the purpose set forth.

4. In combination, a journal-box having slots in its sides, and a lubricant-device com- T prising bars projecting through said slots below the journal, springs depending on the outside of the box and connected with the projecting ends of the ha e to carry them, a

lubricant-holder supported within the box on said bars, and a perforated plate surmounting, and provided with depending flanges to lap the sides of, the holder and having projections on its upper surface at the perforations, forming lubricant-confining spaces and bearing against the journal, for the purpose set forth.
