4 Claims. (Cl. 308-89) This invention relates to journal boxes of the type used on railway cars in which a packing is disposed in the box under the journal for keeping the journal lubricated.

The object of the invention is to provide an efllcient and inexpensive device, which can be readily put into and taken out of the journal box, for keeping the packing in its proper place.

The device of the invention is intended particularly for use with journal box packings in which the waste and the springs interwoven with the waste (when the latter are .used) are enclosed in a cloth envelope or envelopes as disclosed in application of the present applicant filed 5 January 25, 1935, Serial No. 3433 (U. S. Patent 2,049,225, July 28, 1936); and in such case the device serves. not only as an aid in holding the packing element or elements against the under side of the journal-aiding the springs, which are 20 distributed through the waste, in this respectbut prevents the flange or rib on the outer end of the journal from cutting or wearing the envelope.

The device, however, might be used to advantage in arrangements where the packing was not enclosed in an envelope or envelopes. case the device would help to maintain the packing in its proper position and prevent it from working out into the front of the box and rolling out of place particularly in cold weather when the oil is sticky.

Fig. 2 is a sectional view on line 2-2 of Fig. l,

and

Fig. 3 is a view in perspective of the packing retainer.

The journal box as shown in the drawing is of a common type. The body of the box is shown at it and the cover at H. The journal I2 is formed with the usual end flange l3. H represents the brass and I! the wedge which is ordi- 45 narily formed with an opening II for convenience in removing the wedge from the box when the brass is to be replaced or repaired. The main body of packing, which preferably consists of cotton or wool waste l1 and coil springs i8 dis- 5 tributed therein and interwoven therewith, is enclosed in a soft and oil porous envelope l8 and is arranged under the journal I! with the outer end of the envelope bearing against the end flange 13 of the journal. Arranged in the portion 55 of the journal box outwardly of the journal is In such .pose consists preferably of a spring wire 22 bent to form legs 23, 23, preferably provided with loops 24, 24 to increase the resiliency of the legs. The legs 23 are connected by a cross piece 25, the middle portion 26 of which is preferably offset so as to give an effectively wider bearing of the device on the plug of packing 20. The wire 22 is formed with angular and portions 21, 21 which are adapted to extend into the opening it in v wedge IS. The device is proportioned so that it has to be sprung into place between the wedge and the packing 20. That is, in this operative position it is under very considerable spring pressure. By means of this device the end of the envelope is adjacent the flange ii of the journal, is prevented from overlapping the flange and being cut or worn by the rotation of the journal. The packing retainer also tends to keep the main 30 body of packing I'I, whether enclosed in an envelope or not, in contact with the J ournal thereby increasing the efliciency of the packing as means for transmitting lubricant to the journal. In cases particularly of packing not. inclosed in an envelope the retainer keeps the packing in place and prevents it from working out toward the front end of the box and rolling with the journal.

The spring retainer is interlocked with a non-' rotary portion of the journal box assembly (the wedge in the present example) so that it cannot be rotated or displaced by movements of the journal or packing material. The retainer will not be disturbed by the opening or closing of the lid H, and is so shaped and positioned as not to interfere with the oiling of the packing. However, the retainer may be easily removed by flexing the legs and snapping the ends out of interlocked engagement with the wedge, if the packing material is to be removed or replaced. 5

The intentionis to claim all variations and modifications of the devices and combinations disclosed within the scope of the appended claims.

I claim:

1. In combination with a journal box, journal,

brass and wedge, the latter formed with an opening in its outer end: a lubricating packing in the box under the journal; 9. body of packing bearing against the aforesaid packing and extending beyond the end of the journal; and a spring packing retainer comprising a spring wire, the ends of which are engaged in the opening in the wedge and the middle portion of which bears against said second-named body of packing.

2. In combination with a journal box,- journal, brass and wedge, the latter formed with an opening in its outer end: a lubricating packing in the box under and extending outwardly beyond the end of the journal; and a packing retainer consisting of a spring wire bent to form legs, a middle portion to bear against the packing and end portion to enterthe opening in said wedge.

3. In combination with a journal box, journal, brass and wedge, the latter formed with an opening in its outer end: a lubricating packing in the end: a lubricating packing in the box under the journal and contained in one or more envelopes:

a body of packing bearing against the aforesaid packing and extending beyond the end of the journal: and a packing retainer consisting of a wire bent to form spring legs, an offset middle portion to bear against said last-named body of packing and end portions to enter the opening in the wedge.
