Application June 7, 194 5, Serial No. "598,060

In "conventional practice, railway :cars, :or the trucks of railway cars, :are borne :on axle journals, each of which is received in :a journal box equipped with :a journal bearing resting on the journal and held in place in the journal box Joya wedge. The journal and the bearing are lubricated by a packing of oiled :waste carried in the lower portion of the journal box in contact with the under surface of the journal. The packing should be loose enough to hold the maximum :of oil consistent with full wiping contact with "the lower surface of the journal to continuously lubricate it as the journal revolves. But the :waste must not :get between the journal and "the bearing, :for in that position it impairs or prevents proper lubrication :and causes What car .men call waste grab, resulting in a hot :box.

The principal object of this invention is to provide a packing retainer that will confine the packing to its proper sphere, within suitable limits of movement when the motion of the journal :is reversed, and will eifectively collect all the loose and short ends of the packing and prevent their being carried .up to the edges of the journal .bearmg.

. Generally speaking, .this is accomplished by providing apacking retainer having sidepieces to overlie the packing at each side of the journal, a front piece connecting the side pieces :and the cover to overlie the packing beyond the collar on the ournal, andwa ;post:rising from each :side. piece to a point adjacent to the top of the journal box. This retainer hosts with the packing and allows the packing to move with each reversal of rotation of the journal, as it should, to prevent or break up glazing, but it retains the packing within the limits-setby the side pieces coming in contact with the lugs inside of the journal box and the ,posts striking against the top of the journal box. The particular arrangement here disclosed collects all loose and short ends of the packing on the side pieces and cover plate, from whence they are easily removed.

In the accompanyingdrawings, Fig. 1 is a perspective view of .a journal box equipped with a retainer according to this invention, a portion of the box being broken :away to show'the parts on the interior;

Fig. 2 is "a perspective view of the retainer removed from the journal box and reversed end'to end with respect'toFig. I1;

Fig. 4 is a half end view and half transverse vertical section of the journal -box and associted parts shown in Figs. 1 and 3.

In Figs. 1, 3, and 4, the journal box indicated generally by In is a 5 x 9" A. A. R. standard freight car journal box, details of which may be 5 Claims. (Cl. 308-49,)

found in Car Builders Cyclopedia, .1943, pages 1163.:and 1164. The journal 2H has the usual .collar .12 at its outer end. Resting on the journal is the journal bearing I23 having projections 51:4 whichcontact lug 15 .on the inside of the journal box to limit the inward movement of the bearing.

The top of the bearing has polygonal surfaces t6 adapted to be received within corresponding surfaces all "onthe under sideof .a journal bearing wedge 11:8 provided with surfaces 19 contacting with the .inner faces of the lugs 15 to limit the lateral motion of the wedge within the journal box. Outward 'motionof the wedge is limited :by its :end coming in .contact with downwardly directed lugs 20 at the front of the journal box, and inward movement of the wedge is limited :by the shoulder 2d .at the inner end of the bearing.

The journal box :is packed-with an oily mateausuazl'ly .oil soaked waste :22, which fills the lower portion of the journal box up to about the middle :or horizontal diameter .of the journal. Asthe journalrotates, the waste continually wipes the-surface of the journal presented to it, and thus .centinuallysupp'lies it with the thin layeror coating of oil necessary :to lubricate theadjacent surfaces of the journal and the bearing.

llhe details of :all the things heretofore mentionedand others common :to journals and journal box arrangements are familiar, and it is deemedrsuflicienttomerely refer :to the (JarBuilders Cyclopedia, above mentioned, without further :description.

The-preferred form and construction of a packing retainer embodying this invention is best shown in the perspective view (Fig. It includes two side pieces, generally indicated by 24, connected at their *front ends by a front piece 25. They are here shown, and preferably are, of angle section :with the flanges 26 and 2:! arranged vertically an'd the flanges .23 and 29 horizontally. The angle section may be either rolled .or pressed metal, and in the present-construction portions of the horizontal flanges are cut away to allow for the corner :bends "30 at the juncture of the side and front pieces, and when the adjacent faces thus formed-are brought together they are welded as indica'ted at 3 l,'-producing'what for want of a betterterm' may be called a U-s'haped frame. A cover plate =32 extending between the side pieces 2 adjacentto the front piece is welded on the horizontal flanges 28.

inwardly with respect to the cover plate the flangesZB arecut awayattfl to provide clearance for the "collar l2 on the end of-the journal.

Posts *33 have their lower ends welded to flanges 26 of the side pieces 26 and extend upwardly toward the top of the journal box.

As an example of specific construction that has been found satisfactory for this size and type of journal box, the retainer shown in the drawings course, suitable variations will readily be made by others to suit particular conditions.

From the drawings, it will be seen that the side pieces 24 overlie the packing at each side of the journal, and they are so related to the side walls of the box that neither piece can at any time come in contact with the journal. 7 But the upper edge of each side piece may come in contact with the lower portion of the corresponding lug on the inside wall of the journal box to limit its upward movement. V V

The posts .33 rising from the side pieces 24 to points adjacent to the top of the journal box clear the sides of the journal box and the sides of the journal bearing and journal bearing wedge, and are thus free to move within the limits of the allowable dimensions.

The front piece 21 and the associated cover plate 32,.which obviously may be made in one, overlie the packing outwardly with respect to the collar E2 on the endof the journal, leaving clearance, as shown in Figs. 1 and 3, for access to the packing 22 for'spooning and adjusting.

Assuming the journal box to be properly packed with just the right amount of oil waste, the retainer is inserted to the position shown in Figs. 1, 3, and 4 overlying the packing, where it floats with the packing and allows the packing to move within the clearance provided, as the occasion of service requires, due to the rotation of the journal and the reversal of that rotation. Constructed as described, it has just sufficient weight for the purposewithout putting enough pressure on the packing to interfere with proper operation. If the packing starts to roll up in the back of the box, it will raise the corresponding side piece 24 until the upper edge of the flange 26 comes against the correspondinging lug l5, when no further rolling of the. packing will be permitted. If the packing starts to roll up in front, it will raise the corresponding side piece 24 until the post 33 carried by it comes against the top of the journal box, when no further rolling will be permitted.

Experience in actual use with the construction here shown reveals the fact that all loose and short ends of the packing that get free from the mass collect upon the horizontal flanges 28 and the cover plate 32, from which they are easily removed from the box, and it seems clear that the packing as a Whole remains cleaner and lasts much longer than would be the case without the' retainer. 7 V

The retainer is always free and can be easily inserted or removed. Therecess 35 in the top of the box just behind the lugs 20 affords sufficient space for the upper end of the posts 33 to let the notched portions 34 of the side pieces 24 clear the collar [2 as the retainer is moved into or out of position, which operation is very easily accomplished without tools.

In this connection, attention is directed to the curved inner end portions 36 of the side pieces 24, which are so formed to prevent picking up the packing as the retainer is inserted or removed from its position in the journal box. The curve 4 is here shown as chiefly in the horizontal flange 2B, but may be made by an appropriate bend in the angle section as a whole followed by removing the upper corner of the vertical flange 26.

We claim: a
