Description
Unidrta lefoffic This invention relatesto improven-tents`iin"v` car j ournalbearings, and 'inore particularly to` th carjournal bearings, 'wherebfjthe use@ of such particular materials bringsY about newgf'improved, unexpected and beneficial results. s Y u 011e .Off the m'OSt. Ssrus Problems Qf .rallradsjis the hot-box. Despite' manyifimany years .of "reseA chgand attempts to improve railway car journal bearingsj'fthese journal bearings still vget hotanjd bring about breakdowns inequipment; s' One of theprincipal `causes lof the hc t`boxt'is`V use of conventional cottonwasteasl'thefrnatei'ial for applying lubricant to` the railway car journal bearing. J'In the usual railway car journal bearii1gs,`fthe stutling'fbox in which the bearing isloca'tedfhas af rnas's of'cotton= waste located inV the'bottom 1portionthereofjxvli hjrnassjof waste is soaked with lubricant. A s .th urnal, tu 1jns, lubricant is appliedjto the journ I fffrorn tliecottou' waste. Unfortunately, as the` journal lr'otates',Y sometimes spine of the cotton waste is picked up'by tliejournalandis carried between the journal and the yjournal .bearing,orE brass as it issometimes reference; Oncetheroffsm waste gers between the journal ,and 'tl'e journal brass; it'kisMburned, carbonized, or c olfedA by. the;l hig 'ftemper'ture caused by friction between the journal'`a`nd thel` ea`rin`gf- E The carbonizingorpokingof the cottonwastefresult's abrasive whichfscores die journalq4 'A" scfredjournal is more apt to grab onpickup' cotton wasteand draglfit between the journal vand the'.journahbrassfjani thus, once the `journal is s oedthe tendency t' get `a1hot`bo x, is greatly increased'. l
in a gritty substance, vand'this vgritty substance' actsa'san the journal in dragging cotton waste up..lbetggeen the b journal and the jotrnalbrass. How e'igjnne of these devices have/been: fully vrelctiif and s'rlldng as cotton waste is'use'd for feeding kor applyinguoil;` to tHe/journal, some of the cotton wastelyvill be ,draggedf' up bt'weentlie journal and the journal brass.
Most of the devices tried, to date, to prevent waste grabs by the journal comprise retainers for holding the cotton waste tightly against the underside of the journal and for preventing the cotton waste from creeping up between the journal and the journal brass. The lack of success of these retainers is due,k in large part, to the fact that a slightly scored journal picks up cotton waste and drags the cotton waste `past the retainer'into the journal brass.
Thus, one of the objects of this invention is to provide means for eliminating the above referred to causes of hot-boxes in railway car journal bearings.
Another object of this invention is to provide a lubricated journal for railway cars wherein the` possibility of hot-boxes by reason of carbonizing or Coking of the lubricant applicator is eliminated, and whereby waste retainers may be eliminated from the journal-box.

The opposite'sides of the journal bearing 12 engage vertical guide ribs 26:-'26 formed on the opposed inner side facesof the journal box 16. -Lugs 28-28 on said bearing IZ-engage the forward faces of` the guideribs 2 6-26 to hold the bearing in position. The inner end of'the wedge 14'engages an upstanding collar portion 30 formed on the bearinglZ, and the other end of the wedge Y14 is positionedV back of a lug 32 located near the open side of the journal box 16.
Lubricant is applied to journal 10 and to the bearing ained bysubstitutng, forgthef body of cetton'zyvast tioned beneath the journal so as to extend .upwardly at .the sides .of the journal toa position near, butlpreferably slightly `below the center of the ljournal 10. A portion of ythe b ody ofmateriall maybe formadas a wedge 3 8 positioned in 'the forward portion of ythe box 16 to prevent cinders or grit from finding entrance to the main body ofthe lubricant applyingmaterial34.
The body of lubricant applying material 34 is formed of thermoplastic, flame-resistant, res'inousbers as yabove set 1forth and as more thoroughly described as follows,
Ihe absorbent materials suitable for use in the novel journal bearing structure of this invention are thermoplastic resinous bers having a melting point within the range o t 225 lto 400 These fibers unlike cotton, rayon, wool or silk, are characterized by their ability to soften Yand ,melt Yupon subjection :to heat without the formation of ,gritty carbon or coke which, as pointed out aboye, so seriously fouls .the bearings. The resins from which these tbers are made are capable of resisting d ecomposition and of retaining their-original chemical composition Aafter melting within the temperature range of 225 to 400 P.
The thermoplastic libers are preferably -bibulous multilarnentary staple fibers or yarns, since the physical structureof such fibers renders them better capable of absorbing the liquid lubricant, e. g. mineral oils, used in the journal box. For this reason the monotilamentary vfibers Sometimes produced from these thermoplastic resins are not Aas well suited, although a mass of such fibers, wettable -by the liquid lubricant, may be useful. Preferably, however, -the fibers .are both wettable by the lubricant and vpossess a bibulous multilamentary structure.
It is anticipated that fibers prepared from the following thermoplastic organic resins can -be employed in the practice of this invention; polyamides, polyacrylonit-rile, cellulose acetate, copolymers of acrylonitrile and vinyl chloride, copolymers of vinyl chloride and vinyl acetate, copolymers of .vinylidene chloride and vinyl chloride, polyesters and -polyvinylchloride Other fiber-forming resins having the above enumerated .physical .and chemical properties will be apparent to those skilled in .the art.
While there has been shown and described a particular embodiment of this invention, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the invenytion and, therefore, it is intended in .the appended claims to -cover `all such .changes and modifications as fall Within thetrue spirit and sc opeof .the invention.
