SELF-OlLlNG JOURNAL-BOX.

SPECIFICATION forining part of Letters Patent No.'51i,144, dated December 19, 1893. Applicationfiled February 2'7, 1893. Serial No. 468.833. (No model.)

To all whom it may concern.-

Be it known that I, HARRY W. HILL, a citizen of the United States,res iding at Cleveland, in the county ofOuyahoga andiState of My invention relates to self-oiling journal boxes.

The objects are, first, to provide means for,

automatically delivering a copious supply of oil to the shaft bearings; second, to prevent the exudation of oil from between the base and cap of the box; third,for preventing un-' pleasant results from the accidental overflowiug of the oil receptacle.

YVith these ends in view, the invention consists in the construction and combination of 1 parts hereinafter described and definitely pointed out in the claims.

In the drawings, Figure 1 is a side elevation of my improved journal box, shown partly in section. Fig. 2 is a plan view of the same, with a portion of the cap removed. Fig. 3 is a vertical sectional view on line 3-3 of Fig. 1. Fig. 4.- is a vertical sectional view on line 4-4: of Fig. 2; and Fig. 5 is an end view of the ring with which the oil is lifted from the oil reservoir.

Referring to the parts by letter, A represents the base, which contains the'lower half of the bearing for the shaft. In the lower part of the base below the bearing is acavity a, which serves as a reservoir for oil.

E represents the removable cap, which contains the upper half of the shaft bearings. In the upper part of the cap is a cavity 19, which is divided as hereinafter described, so as to form two oil receptacles, from which oil is delivered on to the shaft bearings through the holes I) 2). Near the center of the box is an annular groove 0 in both the base and cap. The lower part of the groove enters the oil reservoir a, while the upper part opens into the cavity 17. Near both ends of the box the.

internal annular grooves F F are formed in both base and cap, and the lower parts of the said groove communicate with the oil reservoir a. The outer edges of these grooves should n0t,preferably, touch the shaft.

Securely bolted to the shaft, which is journaled in the box, is a ring D. This ring lies in the groove C, and one of its functions is to act as a set collar to limit the longitudinal movement of the shaft in the box. In the edges of this ring is a series of radial pockets d, a part of which are open on one side,

While the alternate pockets are open on the 7 oil flows into the several pockets, in which it is lifted from the reservoir and thrown against the roof of the cavity 19 in the cap. Depending from the roof of this cavity b, di-

rectly over, the center of the ring D, is a deiflecting boss W, by which the oil is turned to the right and left into one or, the other of the -two oil receptacles formed in the cavity 1) by the ribs 11 which rise from the floor of said cavity on both sides of the ring D. Oil thus drawn from the reservoir a and discharged into the receptacle in the cap, flows through the holes I) b on to the shaft. It distributes itself in all directions and finally flows into the grooves F F or into the middle groove 0 and theuce'back to the reservoir a. By the construction above described, a copious supply of oil is delivered constantly on to the shaft, and the excess flows back into the lower reservoir, from which it is again lifted and distributed as before explained.

In all journal boxes which have a base and a cap, there isa tendency on the part of the consist of the notches a which connect the canals referred to with the grooves F. The oil which, by the pressure of the shaft, or by capillary action, is forced between the base and cap, runs into these canals, which interrupt the capillary action; andfrom these canals the oil is drained by the grooves F into the receptacle a.

To prevent the overflowing of the oil receptacle in the base, or to be more exact, to provide means whereby the oil, if too much be fed into the base, may beeaught without loss and before it has made the box greasy, I form in the base, and preferably integral therewith, one or more small vertical overflow pipes L, which are open at their upper ends, and which discharge through the bottom of the box. The position of the open upper end is below the lowest point at which'the oil might overflow from the ends of the box, whereby when too much oilis put into the reservoir, it will flow throughthe overflow pipe L hereinbefore referred to.

a removable cap having two oil receptacles in'it'siu'pper part on opposite sides of the oil lifting device, and openings from said recep- '-ta'cles totheshaft bearing, with an oil lifting device adapted to lift the oil from the lower reservoir and to discharge it into the upper receptacles,substantially as and for the purposespeci'fied.

- 2. In a-self-oiling journal box, the combination of abase'having an oil reservoir in its lower part1. and a cap having a cavity-in its ju'pperfpart and openings'from said cavity to theshaft bearingon'both sides of'the oil'liftjug-ring, both base and cap being provided with an annular groove adapted to receive the oil lifting ring, with an oil lifting ring adapted to be secured to the shaft with'its lower edge extending into the oil reservoir; and a deflecting boss secured to the roof of the cavity in the cap, substantially as and for the purpose specified.

3. In a self-oiling journal box, the combination-of a'base having an oil receptacle in its lower part, and a cap having an oil receptacle in its upper part, with a ring adapted to be secured to the shaft and to enter both of said receptacles, said ring having radial openings in its edge, a part of which are open on one side anda part on the other side, substantially as and for the purpose specified.

4. In a self-oiling journal box, the combination of a base having anoilreservoir in its lower part, with a cap :having a cavity in its upper part, and holes leading from said cavity'to the shaft bearin g, said base andicap being provided with a substantially-central annular groove 0. adaptedtoreceive'it'he'oil lifting ring and theann nlar end grooves F F,
