LYMAN P. MOORE, OF CHICO, CALI IFORNIA racxme RETAINER Application filed This invention relates to railway rolling stock and particularly to a retainer for packing of the journal boxes of the journals of railroad cars.

Such journals, as is well known, are supported by inverted bearin sections, mounted in the boxes, the latter being stuffed with packing,usually cottonwaste, which is placed about the portion of the'journal below the hearing and of course is prevented from ac-. tually leaving the box by the front cover of the same. There is considerable space, however, between the cover and the outer end of the journal and it frequently occurs that the packing loosens up and works away from the. ournal and into said space where it ceases to function to efficiently lubricate the journal and bearing. As a consequence the latter overheats and a hot box results.

The principal object of my invention is to avoid the occurrence of such hot boxes by preventing the packing from thus moving away from its properly packed relation about the journal by providm a retaining member which is placed in the ox and which is so constructed as to efficiently hold the packing in its proper place.

At the same time the retainer is easily removed whenever necessary to withdraw old packing and replace the same with new.

Also my retainer is of such a nature that it may be applied to standard journal boxes without necessitating any changes of any character being made to such boxes.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claim.

In the drawings similar characters of reference indicate corresponding parts in the several views: I

Fig. 3 is a perspective-view of theretainer detached. g

Referring vnow more particularly to the characters of reference on thedrawings, the journal structure comprises the boxl, in the upper portion of which is mounted the inverted bearing member 9 against which the journal 3 bears; the sides of the bearing and journal being spaced some distance from the sides of the box. The front: of the box as usual curves upwardly in front a certain dis tance as shown at 4 to the lower edge of the covering opening 5. These parts are all standard and I do not change'the same in the slightest degree. The packing 6 is disposed about the lower portion of the journal and extends upwardly in the space between the journal and the sides of the box to'a point substantially horizontally alined with the axis of the journal, and also substantially fills the lower portion of the spacein' the box in front of the journal and below the cover opening.

My improved packing retainercompris'es a single piece of spring steel rod. This rod is bent to form a pair of parallel arms 7, spaced apart a distance suflicient to fit between the journal and the sides of the box,""* and formed'with vertically disposed spring loopsv 8 intermediate their ends. these-arms are connected by a cross portion 9 which centrally of its extent is'forme'd with a substantially horizontal and'forwardly pro-' jecting loop 10. At their other ends the arms 7 are provided with upstanding prongs 11 disposedat an angle of approximatelyl to the arms. The dimensions of the retainer are such that when in position, the loop 10 bears againstthe upper surface of the lower forward por ion of the packing and abuts 90 against the front surface 4; of the box below the cover opening; while the cross member 9 extends across and rests on such portion of the packing between the journal and the front of the box. The arms 7 slope upwardly rela tive to the journal and for a portion of their length bear against the top surface of the acking in the side surfaces of the box.

At the same time the tips of the prongs then bear against the roof of the box as shown At one end 80 prevents outward movement of the. prongs from their engaged position with the roof, and said retainer prevents displacement of. the packing from its proper compressed condition about the journal. The spring loops 8 permit the arms to yield when the prongs te position of the prongs. These loops also 30 provide a greater area of surface to engage the packing than the bare rods would provide. When it is desired to-remove the retainer, it is only necessary to pull the prong portions 11 both downwardly and outwardly until they pass through the cover opening. The entire retainer. can then obviously be drawn clear of the box.

From the foregoing description it will be .readily seen that I have produced such a de- Vice as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claim.

Having thus described'my invention what claim as new and useful and desire to sem cure by Letters Patent is:

packing retainer for a journal box, said box having a bearing member against which the upper portion of the journal bears, said journal and bearing being spaced from theside walls of the box, and packing partially filling the box from the front thereof and extending into the space between the journai and box; said retainer comprising side arms to extend upwardly and inwardly of said space and adapted to bear against the upper forward surface of the packing therein, extensions on the inner ends of said arms projecting upwardly thereof to engage the roof of the box in said space, and a horizontal member connecting the opposite ends of the arms to bear against the packing in front of the journal and to engage the front wall of the box. I

In testimony whereof I aflix' my signature. LYMAN P. MOORE.
