PACKING-SUPPOR'IIN G DEVICE.

My invention relates to improvements in journal box packing supports.

The principal object of the invention is to provide an improved packing supporting device adapted to maintain the packing in contact with the journal to be lubricated,

and which admits of the packing of the journal in, substantially the same manner absorb the freeoil therein, and which will prevent the packing from being carried by the journal upwardly under the brass by the rotating journal, or moving longitudinally of the box out of the packing space.

Another object is to provide a device comprising a pair of complemental members adapted to be inserted in a journal box through a door thereof, one on each side of the journal, and being resiliently connected at their lower edges and having resilient.

contact with the side walls of the journal box which will hold the packing against the journal, even when the same'is subjected to the hammering incident to passage of the car over rough tracks, such as crossings, frogs and low oints and vibration caused by the ground being frozen, and which will prevent the packing from settling away from the journal during a period of nonuse, thereby obviating the necessity-for lifting and loosening the packing as is the necessary general practice at the present time.

A further object is to provide a packing supporting device which may be provided with a gate, or the like, as an additional .means for preventing the packing from moving longitudinally of the box towardthe door thereof and out of the packing space.

Other objects relate to various features of construction and arrangement of parts Application filed June 19, 1926. Serial No. 117,023.

Flg. 1 1s a vertical sectional view taken on line 44:, Fig. 3.

Fig. 5.is a detached elevation showing a further modification of my improvements.

Fig. 6 is a broken plan view illustrating the upper spring arrangement. i

In the drawings, the conventional journal box 10 is provided with a lid or door 11, a ournal 12 being enclosed in the box, which ournal is provided with the usual collar 13.

A brass 1' 1 rests upon the journal as" illustrated.

At the present time, it is the general practice to insert packing, such as oiled waste through the opening in the box, into the space beneath the journal, filling the lower portion of the box up to a level, approximately half way up on the journal. The packing is forced into the box in such quantity as to fill the lower portion of the box and to contact with the lower portion of the journal.

After a period of use the packing tends to settle away from the journal and necessitates lifting or stirring up the waste in order that the journal will be properly lubricated. It also quite frequently happens that strands of the waste or packing are carried upwardly by the rotating journal. under the brass 14, which often is the cause of hot boxes. In addition to overcoming the above disadvantages of the present practice, my improvements contemplate also the use of considerably less waste than .is required in packing the boxes in accordance with the present practice.

In Figs. 1 and 2 are shown a pair of complemental packing supporting members 15 formed of sheet metal. The metal is resilient enough to flex sufliciently to permit the same to be inserted in position through the door of the box, and, when deflected to the full lineposition, shown in Fig. 2," from the dotted line position, by the pressure of the packing 16, to exert pressureon said pack ing and hold the same in contact with the journal. The members 15 extend from the rear of the journal box to the forward side thereof. The forward ends 15 of members 15 thus extend somewhat beyond the end I of the journal 12 and serve as guides for directing the packing intothe spacebetwcen said members and between the journal. and the floor of the box. The members 15 are flexibly connected adj acent. their lower edges by means of springs 17, two of which are shown in the drawings, although moremay be employed, if desirable. The upper portions of the members 1 5. are slit to form thethe collar 13 of the journal?12.. The packing 16 is then insertedby meahs of an ordinary packing tool, between the members 15 with sufficient pressure tocause the said members to spring; outwardly-slightly, as indicated by the full line position inFig. 2.

By means Ofl the; fiexibleconnections at the lower edges of the members 15. which give sufficiently to: permit the inembersto be inserted in a. standard box through the door thereof and-the resilient contact with the wall ofzthe;box,.the members exert a pressure on the. j nacking whichholds the same. against the journal: even under severe conditions of travel, as well as during periods of non-use.

It is therefore unnecessary in: the use of my improvements to raise the: packing frequently as the practice at thepresent time.

It will also be seen'that the packing 1.6 is

adapted to rest upon the floor of. the box.

whereby it can.- absorb any tree: oil which may ,be' present. arrangement and proportions of my. improvements are such that" the membeis- 15 exert the greatest pressure on: the packing adjacent the upper port-ion of the latter, which preferably terminates in: a plane lower than the horizontal center of the journal; The eflect: of this construction isthat the journal is less likely-to carry strandsof packing upwardly under the brassto cause the trouble referred? toabove,,as any tendency of the packing. to move with. the

.' journal is resisted.- by the relatively. con- -wire having suflieient resilience to recoverstriated passages between members 15 and.

the journal. To further assist in the gripping ofthe packing by the support, and to" prevent the. grabbing action of the journal,

a, number of1openings. 19- are provided. in the. members, 15. V

In the form ofinvention shown in Fig. 3,

the packing supports 20 are formed of. woven wire, which is preferably a resilient steel itsishape after deflection but flexible enough to permit the same tobe passed around the collar 13 of the journal 12: In this form,

It will. be notedi that. the

the lower edges of the supportsare con-' nected by coil springs 17 as in the above described modification, and they are also provided with springs21 adjacent their upperedges. These springs are suitably securedto the members 20 by any approved means as being interwoven with the mesh of. said:-members:and having their ends bent outwardly, as shown in Fig. 1, to contact with the'inner walls ofthe'box10. The device functions similarly to the above described modification, the reticulated construction serving to provide sufficient con-.

tact with the packing to prevent the same from being grabbed and moved upwardly out of position by the rotating journal, and the guide portion 20 asslstmg in directing the packinginto the packlng space.

I11 5,- I have shown a further modification of my supporting device formed'of sheet metal and having the general shape of the member 15, shown in Fig. 1. Instead of being provi ded with openings 19 of Fig.1,

the support 22 is provided with depressed portions orcorrugations 23, which arearrangedin staggered relation and serve 'to prevent the packingfrom beingcarri'ed upwardly under the brass of the journal and to prevent any other displacement of*thepacking. The support 22 is slit to form upper springs 24.: The" lower edges of the members 22. are also connected by springs 17 as. in. the previously described modifications. Giiide pontions 22 are-also provided;

It frequently occurs, due to some. action of the journal (probably the lateral movement' of thesame), or to the improper pack-' ing of the box, that thewaste or packing material will tend to creep or move toward thedoorofzthe box. andfrequently actually flows through the door, causin'g'loss of oil and: permitting the eintrance of dust and other foreign particles, as well as permitting the packlng to dron from contact withthe lower: portion of the journal. It will be apparentthat all forms of supportingmembers described. above will tend to preventthe longitudinal movement of the wastetoward the box door, due to the reticulated r construction, the openings therein, or the corrugatlonsiof the dlfierent' forms. I; condesired, with each of the above described template also the use of a gate 25, when forms of packing supports, which: gate is adapted to be hinged, as g at 26, or otherwise suitably secured to one of the packing supporting-members and to have a removable' latch connection; with the oppositemem-.

her. r

With the. form of invention shown in Fig.

.1, a suitable opening 28 maybemade-in; one of. the members 15 to receive thebentover free end 271 of gate 25,. while in the form shown in Fig; 3= theend27 can be passed through the mesh of saidfimemheraas will be clear. An opening 28 may also be formed in the supporting member 22, shown in Fig. 5, for receiving the latch member 27. The member is shown as being formed integral with the member 27 and as comprising merely a turn or two of wire, which permits the gate to be extended to different lengths in accordance with variations in the quantity of packing used, as will be obvious.

As shown in Fig. 1, for instance, the gate 25 is positioned a short distance to the left of the collar 13, as viewed in said figure, thus permitting the packing to lubricate the collar 13 which is desirable in case of an overriding brass, but serving to hold the packing against movement toward the box opening.

Although I have shown certain features of my improvements for the purpose of illustration, it will be apparent that various changes may be made therein without departing from the spirit ofthe invention as defined in the following claims.

What I claim is: r

1. Journal box packing supporting means comprising a pair of members resiliently connected adjacent their lower edges and having springs at their upper edges for urging said members in a direction to hold the packing against the lower portion of the journal, said supporting members having their inner surfaces formed to resist displacement of portions of said packing by the rotating journal, and means extending transversely between said members for preventing the movement of said packing longitudinally of said box toward the door thereof.

2. Journal box packing supporting means comprising a pair of members resiliently connected adjacent their lower edges and having springs at their upper edges for urging said members in a direction to hold the packing against the lower portion of the journal, said supporting members having their inner surfaces formed to resist dis placement'of portions of said packing by the rotating journal, and means extending transversely between said members for preventing the movement of said packing longitudinally of said box toward the door thereof, said last named means comprising a gate secured to each of said members.

In testimony whereof, I have subscribed my name.
