PACKING-RING.

Specification of Letters Patent;

Patented Oct. 9, 1906.

Application filed April 19, 1906. Serial No. 312.825.

for the convenient introduction of a packing ring into a journal-bearing and to provide for preventing creeping of the packing under the influence of the rotary movement of the journal. i

With these and other objects in view the v present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the a pended claim.

In the drawings, igure 1 is a longitudinal sectional view of a car-wheel hub equipped with packing-rings of the present invention. Fig. 2 is a cross-sectional view on the line 2 2 of Fig. 1. Fig. 3 is a detail perspective view of the packing-ring embodying the features of the present invention. Fig. 4 is a plan view of the liner member of the acking-ring.

Like characters of reference esignate corresponding parts in all of the figures of the drawings.

While the present invention is useful in many relations, it has been shown in connection with a mine-car wheel, a conventional form of hub being shown at 1 in Fig. 1 and provided with the usual s indle-reoeiving opening 2 for'the reception '0 the spindle 3 of a car-axle 4. Lubricant may be fed to the bearing in any suitable mannersay, for instance, from an annular oil-chamber 5 in the hubby means of an absorbent 6, seatedin an o ening 7, extending from the oil-chamber to t e spindle-o ening of the hub. If desired, the inner en of the absorbent may be held in a cap or'case 8, snugly fitted in the opening 7 and provided with perforations 9, through which the lubricant is ada ted to have access to the spindle. The oil-c amber is capable of being filled through an opening 10, which pierces one face of the hub and has a branch 11 communicating with the oilchamber.. A spring-pressed valveor closure 12 is employed in the opening 10, there being an open-ended thimble or bushing 13 threaded into the outer end of the opening 10,so as to form a valve seat for the valve 11. Although a specific means for feedin oil to the bearinghas been shown, it will 0 course be understood that any approved means may be employed.

In car ing out the present invention an annular c annel 14 is formed in the walls of the spindle-opening 2, and an o ening 15 is drilled through the adjacent en' of the hub so as to intersect the back of the channel.

The packing-ring for introduction into the channel consists of a yieldable strip 16, preferablv of leather, which has its ends reversely notched, as at 16' and 17, so as to form a break-joint engagement between the ends of the strip when the leather is folded into the form of a ring. When folded into a ring, the leather element is introduced into a split-metallic band 18, to which it is connected in any suitable manner-for instance, by fastenings, such as rivets 19care being taken to have the joint of the leather liner element 16 disposed somewhat remote from the joint or space between the ends of the metal band. One end of the metallic band is directed outwardly so as to form an ear or projection 20.

In practice the free end of the liner ele ment is s' rung out of en agement with the other en as indicated by dotted lines in Fig. 3 of the drawings, whereupon the entire packing element may be compressed and orced into the openend of the spindle-opening 2 until it comes into alinement with the channel 14, whereupon the ring will spring out and fit snugly Within the channel. In introducing the packing-ring into the spin die-opening care should be taken to have the projection 20 in alinement with the opening 15 in order that said projection may be received within the seat or recess formed by this opening, and thereby prevent cree ing of the packing-ring under the influence o the rotary movement of the spindle. The preventing of creeping of the acking-ring 1s a very important feature of t e resent invention, as it prevents wearing of t e sides of the ring against the sides of the channel.

Having thus described the invention,what is claimed is A journal-bearing having an internal annulan channel IiIOVldGd with a seat extending at right ang es thereto, a flat spring-band having one end provided with an external projection, and a split liner element connected to the band and havingone end projectbend and its projection being entirely sur- 1o ing beyond that end'of the band having the rounded by the bearing.

rojection thereon, the other end of said iner terminating short of theother end of the band, the projecting portion of the liner being disposed beneath the projecting end of the band and the bend and liner being located Within the channel, the projection on the band being sprung into the seat and said In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
