PACKING-RING FOR AXLE-BOX. BEARINGS.
996,79is. 7 I I Specification of Letters Patent. Application filed May 5, 1910. Serial No. 559,597.
Pate ted July .4, 1911;.
i sa1ne,-' reference being had to the accompanying drawings, and to letters or figures of.
reference marked ,thereon, which form a part "of this specification;
Hithertp the pat-kings for such bearings have been made of leather or felt, which, however; both possess serious drawbacks. Leather packings, for instance, wear out rapidly, unless supplied with an 'ui'idue quantity of lubricant; While felt packings harden, owing to their taking up lubricant and dust. In both cases the joint is rendered defective. 'These drawbacks can be overcome by means of the present invention,- oif which a practical embodiment is illus-' trated in the accompanying drawings,
Figure 1 is a longitudinal section through the bearing. Fig. 2 is across-sectional view, showing the metallic, packing on a larger scale. Fig. 3 is a side elevation of Fig. 2. The box or housing 1, in which the axle 4: is mounted with the aid of ball- bearings 2, 3, is provided with a groove or.rec ess 5 at the inner end. Into this recess there fits aring 7 presenting a flange 6, whereby it can be secured to the box 1 by means of screws 17. The ring is furnished with a perforated bottom 8, constituting a closure for the bearin g, and whose opening 9 is somewhat larger than is actually requisite to admit passage of the axle 4.- ln this ring 7 there is located a metallic packing, consisting of two composite rings 10,11. Each ring comprises two segments,. and the internal diameter corresponds with that of the axle 4;, but the segment-ends do not contact, so that the segments fit tightly to the axle. The segments are set at an angle of 180 to each other, so that the joints between the segment-ends of the one ring are covered byithe other ring. The segments present projecting flanges or rims 12, which abut against each other. These flanges are removed at 13, in inclined direction, and through the grooves thus 'o'usly passed. This is a tension-spring and holds the se ments of the rings 10, 11 uniformly together, both in radial and axial direction. The segments 11 present pockets 15, toaccommodate small helical compresfsion-springs 16. The one end of these latter bears against the segments 11 and the other end against the bottom of the recess 5-, so
that the segments 10, 1,1 areforced against the base 8 of the ring 7, There mightnaturally be more than two segm n s in h ring 10, 11.
The end of the axle 4 is annularly grooved at-23, where it receives a split collar 24, which is held upon the axle by a perforated cap 25. The cap is secured to the formed'an endless helical spring 14; is sinuv ring'24 by studs 26 in the latter, which pass through holes in the cap and receive split-- p1ns27. The purpose of the collar 24: is to take up axialpressures arising in the bearmg.
The new metallic packing is compact in length and prevents the access of dust,
Water, and the like to the bearing. It is also Well adapted for packin movable rods in steam and other engines, or which packings are frequently used consisting of a large number of segments and thus' of undue length.
Having now'particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is:
1. In an axle box bearing, a metallic packing, comprising two parallel abutting rings, each consisting of a plurality of segments, the joints of the one ring being covered by the other ring; and an endless spring wound sinuously around the assembled segments and holding the latter together both in radial and axial "direction; substantially as described.
2. in an axle-box bearing, a metallic packing, (:UtHPl'lSlIlg two parallel abutting rings, each consisting of a plurality o'l' sag: n'icnts presenting slotted flanges, the joints of the one ring being covered by the other ring; and an endless spring passing through the flange-slots and wound siuuously around the assembled segments and holding the latter together-lmth in radial and axial direction, substantially as described.
3. Au axle-box bearing, comprising a housing having a recess at its inner end, an annular member mouutedin the recess ha ing a perforation in its/bottom to receive an E pression springs mounted in said pocketsiLXle, two parallel abutting rings mounted 1n I and bearing against the bottom of the recess.
the annular member each consisting of a In testimony that I claim the foregoing plurality of'segments having flanges diagasmy invention, I have signedjny name in 5 onally slotted, the joints of one ring being presence of two subscribing witnesses.
