Definitions

  • an oil-retaining ring is usually arranged on -the collar of the axle journal, and is proto be suspended on the axle box, and conse-- quently the dust-ring cover has 'had to be bored through and provided with a special cap, in order to accommodatethe suspension means. It was therefore necessary to modlfy .the dust-ring cover, but this could not be done in the case of some axle boxes, because the frame of the vehicle nearly touches the axle box at the point in question;
  • the frame carrying the oil-retaining ring is secured, not on the'axle box, but directl on the dust-ring, so that the dust-ring an oilretaining ring form a singleunit.
  • the invention further consists in thenovel arrangement of thedust-ring, which serves to make a tight joint between the collar of the journal and the axle box and has, hitherto, usually been made of wood, with felt washers.
  • the novel feature in the present dust-ring is that it is'madeof sheet metal, or preferably of two sheet-metal discs, connected together in any way whatsoever. Of these sheet-metal discs, the one carries the 40 actual packing ring of felt or similar ma-' terial, whilst the other ispr'ovided with av suspension .device onwhich the usual. oilretaining ring is flexibly suspended. This arrangement simplifies the construction and,
  • the two sheet-metal discs .areconnected together by curling the upper edge of the one, so that the other member can be inserted under it.
  • two tongues on the one member project through the other member and can be 56 secured by a cotter.
  • the onemember also and return to the oil bath carries two fiat or other springs, which bear agamst the "axle box and press the other sheet-metal disc with its felt washer against the other sideof the axle box.
  • Figures 1 and 2 are respectively a sec- 00 tional side elevation and a front elevation the oil-retaining ring being combined with the dust-ring; j
  • FIGS. 3 .to 8 shew a modification of the' new dust-ring, Fi ure 3 being a" front view of aportion of t e ring, Figure 4 a plan thereof and Figure 5 a longitudinal-section .therethrough whilst Figures 6,7 and 8 are pended from the lower part of the dust ring.
  • the spring 15 is arranged so as t'o ress the'oil-retaining rin a alnst the axle ush.
  • n t is embodiment it is also advisable to protecttbe feltwa'sher 12 of thedust-ring .11 against lateral squeezing in its upper,
  • the frame 14 is made of some kind of bearin metal, for instance brass, and arranged to le the collar at 16, thus taking up the pressure direct and relieving the felt washer. Only when this is done can the oil-retaining ring be suspended on the dust ring without prejudice in the efiicacy of the latter.
  • the dust-ring is composed of two sheet-metal discs or plates 19 and 20, each of which is turned over or flanged at its rim 21 so that the two rims can overlap and enable the two discs 19 and 20 to be secured together.
  • the disc 19 is provided with an annular segment 22 of bearing metal or the like, which rests, at the top, on the axle collar 2 and thereby prevents the upper portion of the felt packingwhich will be 'mentioned later-from being crushed.
  • the disc 19 is rovided with a spring 23, the ends of whic are secured at 24 and 25, serving for the suspension of the oilretaining ring ( Figures 9-11).
  • the other half of the dust-ring consists of the disc 20, which is provided, both at its inner and outer marginal portions, with a large number of holes 26, serving for the attachment, by sewing or otherwise, of strips of felt 27 and 28, represented by dotted lines in Figure 3.
  • the felt strip 27 bears against the axle collar whilst the felt strip 28 makes a tight joint, on the outside, at the rim of the axle box ( Figure 12).
  • the strip 27 is also covered with a strip of leather 29 on the side Where the oil-retaining rin is suspended, in order to prevent any .fi res of felt becoming detached from said felt strip and finding their way into the oilretaining ring and therefore into the oil bath.
  • the rim 21 of the disc 20 is bent over a second 'ime at 30, so that the other half 19 can be'inserted under it.
  • the half 19 of the disc is provided at its lower part with two tongues 31, adapted to be passed through corresponding openings 32 in the other half 20, and a cotter 33 is then inserted through holes in the tongues 31, as a fastening.
  • the two halves of the disc are held together by the rim 30 at the top and by the tongue and cotter fastening 31, 33, below.
  • Theihalf 19 of the 'disc carries on its outer side two flat springs 34, which bear against the wall 35 of the axle box ( Figure 12), and thus press the entire dust-ring outward and cause the felt ring 28 to fit closely all round.
  • the part 19 of the dust ring is cut away at 41 to allow the passage of the hook 36 of the oil-retaining ring; and the part 20 of the dust-ring is provided with a corresponding depression at 42, into which the hook 36' is adapted to enter.
  • the spring 23 presses the oil-retaining ring against the axle bush.
  • the hook 36 like the tongue 39, is bent, after the manner of a crank ( Figure 10), so as to leave a certain space 43 (Figure 12) between the dust-ring and the oil-retaining ring.
  • this space prevents. elt fibres from getting into the oil-retaining ring and therefore into the oil bath.
  • This space is also increased by the fact that an annular depression 43 is provided on the half 19 of the dust-ring.
  • the wiper 38 resting on the lower por tion of the oil-retaining ring can also be flexibly suspended from the dust-ring, in the manner shewn, or in any other way, and without the oil-retaining ring. In any case the wiper is wide enough to ensure that any oil wiped off in the vicinity of the dust-ring will be led away over the partition between the dust-ring chamber and the oil bath and into the latter.
  • This construction is shown in Figs 13 to 15, as a separate embodiment, in
  • the journal 1, collar 2, a'xle box 3 and bearing brass 4 are, as well as the other above mentioned parts, the same as before described.
  • the oi ring 37 has a vertical flange 50" whose"lateraledges are guided under rabbets 51 of securing plates 24 similar to those 24, and which plates also hold the ends of a .wire spring 23* similar to spring 23, to urge the oil returning ring or member against the under side of the collar 2.
  • I claim: 1. The combination with a dust excluding ring arranged for support by the axle collar, of an oil retaining ring yiel ingly supported lair ' journal box, a spring on the dust excluding against the collar by the dust ring for removing oil from the collar, both rings moving verticallywith the axle.
  • scrapers carried by said oil returning ring for scraping oil from beneath a journal.
