My invention relates to railway car Vretarders of the type involving braking bars located in the trackway and. movable into engagement with the wheels of a car for thepurpose of retarding the motion of the car. One object of my invention 1s the provi- Y s ionwin a car retarder of the type described lar parts in both views.

"ingbars 3 and 4 located on opposite sides of t of apparatus for positively guiding onto the 'rails' at the leaving end of the retarder'car wheels' which have been raised off of the rails in passing 'through the retarder.

rails are mounted oncrossties 2 in the usual l -manner, and overwhichcars normally move from left to rightfas viewed in Fig. 1. Associated with thetrack rails land 1a is a car retarder, designated in general by the reference character A., and comprising two brak- "the track rail 1, and two similar` braking bars 3a: and 4a loc-ated on opposite sides of the'track railfla. The braking' bars maybe moved Vtoward or away from the'track rails, that is,

intofclosed or open positions of the retardenf by any suitable means, such fory example, as themechanism shown and described in my fcopending application for vLetters Patent of the United States, Serial No. 307895, filed September 24, 1928, for railway. braking apparatus.

the vdrawing because it forms no part of my conditions present invention.`

vIn'the operation of car retarders of the type describedV itmayhappen under some that the wheels of a car, uponl being engaged by the braking bars are lifted off of the vtrack rails and ride upv on top 'of vthe brakingbarsy When Athis occurs, it is will describe one form of apparatus ein` 'bodying myy invention, and will then point l7 is a similar triangular plate '.Theplate This mechanism'is omitted from desi'rable `-giuide the wheels yof tliecar back onto the track railsat the leavingend ofthe Vretarder in order to prevent the wheels of the car from dropping down, into the trackway and damaging the ear andlad-ing, or 'the apparatus located in thetrackway, or both.

y,For this purpose, I providetwo guide rails '5' and 7 which nia-ybe standard frail" sections,

andwhich, as here shown',"are 'locatedbetween the track rails at theleavi'ng end of the lretarder with the'guide rail lad'j acent the track rail ,1 and with theguid'e railf7 [adjacent the trackV rail 1a. The guide. rails are mounted on riser blocksv 6 securedto thecrossties,2.5

The thickness' of ,the riser blocks l is :such that' the tops lof, theguiderails extend slightly above the topsof the track rails" as best `seen in Eig. 2.." The guide rail 'is bent finter- Y i mediate its ends to form a longjleg fandau l short leg 5h, andthe guide rail `7 ,isV similarly bent tofform a long Vleg 7? and a short leg7b. The left handfend of the leg afof'the guide rail 5 is located adjacent the endl of thebraking bar 3 and the rail 5 is so arranged that both-legsv ofthe bar areinclined'to the rail: 1, sufi'icient clearance being maintained between the rail 1' and the guide rail 5 attheir` nearest point toV permit `the passage ofr a car wheel {ia-nge between the vtrack rail and the guide rail. The left hand end of the legvfa'of the guide rail 7 is locatedadj acentthe end of the braking bar 3a, and the rail "7 'is 'so arranged that both legs yof the barare inclinedto 'the mil lawhle Permitting-,amen fiang'eto pass fully between the Vtracl';` rail 1f* an'clvthe guide rail 7. Located between the trackrail 1 and the leg 5u of the guide raijlf a triangular V'plate v12,l andV `located between :the

track rail' 1a andthe leg`7? of the gu'ide'rail@V j12"is fastened,` by means of'afplurality'fof screws 12a, to a block 13 which, in turn,'is fastened to a tie 2 by means'of a lagV screw 18, `the head of which Lfits' in' al suitable. hole manner as the block 13 is fastened to the tie 2 by the lag screw 18. The parts are so arranged that the upper surfaces of the plates 12 and 14 are parallel with the tops of the track rails 1 and la but are located below theY tops of the track rails a. distance which is slightly less than the minimum depth of any car wheel flange.

Two other flat plates 8 and 10 extend parallel vwith andare in engagement with the track rails l and 1a on the opposite side of these rails from the guide rails 5 and 7, re

` spectively. FThe plate 8 is fastened,`by means of a plurality of, screws 8?", to a Stringer 9 which is secured to the crossties 2=by means of lagscrews 20, and the plate 10 is similarly fastened, by means of a plurality of screws 10a, to a Stringer 11 which is'secuied to the crossties 2 by means of lag screws 21. The

heads of the lagscrews 2O and 21 are located in suitable holes formed in theV plates and the stringers so that the heads of they screws do not extend above the tops of the plates.

' 'lhe parts are arranged in such manner that as best seen-in Fig. 2.v

A plurality of bolts 16, here shown as two Ain numben'extend through the guide rail 5,

the upper surfaces of the plates 8 and 10`are level'with the -tops of the track rails' 1 and 1a block 13, track rail 1,7and Stringer 9, and two similar bolts 17 extend through the guide rail 7 block'l, track rail 1a, andstringer 11, to hold the parts in their proper positions.

Y Whenthe car wheels of a car are raised vfrom ythe track rails by the braking bars of the retarder Av there are several positions which the wheelsmay take with relation to the rails and to the retarder itself. For eX wheel may rideon top of an outside braking y Under 'these conditions, after the car wheel f whoseflange has been vriding on top. of the bar such as 4 and the i'langeof the other wheel on top of an inside 'braking bar such as 3a.

a In vexplainingthe operation of the appa- -ratus,Iv will .assume that the wheels of a car 'occupy' the positions last mentioned above.

brakingbar '3a rolls oi of the yend of the braking bar, the flange of this wheel rides on plate 1 4'. As it continues its forward motion, the f iange'engages the leg 7% of the guide Vrail 7 which guides the wheel kback to its proper 4position with .relation tothe rail 1a. The opi posite wheel which in the meantime has had*` itstread. riding .on braking bar 4 drops onto Plate'. after leaving the retarder and iS guidi ed, back-t0 its position on vthev will as a result of the guiding effect imposed upon the opposite wheel by leg Pof guide rail 7 The operation of the guide rails for the other positions of the car wheels pointed out above is similar to that just described and will-be readily understood from an inspection of the drawi g.

Although I have herein shown and described only one form of apparatus embodying my invention, it is understood `that various changes and modificationsmay be made therein within the scope of` the appended claims without departing from the spirit and scope of my invention.
