enter :when the rake bar is elevated so that -the rakehead will be swung inwardly or ways-are formed in an enlarged portion of g .the rake bar at. the lower end ofthe latter l.and immediately kabove the rake head 'ligas' [clearly illustrated v in the drawings- The , rollers 25, 26 are so disposed thatthejrake bar issnbstantially parallel with the rack 2- and since the guideways 20, 2l are parallel with each other the rake bar will travel in a plane f substantially parallel with the rack 2 with the teeth 19 of the Vrakehead projecting between theslats of the rack; but in' order to'4 throw the rake head outwardly` 4away from the rack, when it is being lowered, we

provide, at the lower end of the channel 20,v

a pivoted deilecting plate or member 31 which'Iservesto throwl the roller 26 out of the upper'end of the channel 29 and conse-v quently to throw the rake head outwardly or forwardly so that the roller 26 will en-vl gage the outer face of the rib or flange 22 when the rake bar moves downwardly. The upper end of the channel 2O is provided with an inlet 32 which is adapted to permit 'the roller- 26 to return to said channel 20 and which is formed by slitting the flange or rib 4,22 andubending it outwardly to provide the inclined or cam portion 33., It will be seen that when the rake bar lowers and the ineline 33 passes beneath the roller 26 the rake head will be permitted to swing inwardly i against the rack and when the rake bar is again raised the roller 26 will pass through` the inlet 32and .into the channel- 20. The

deiiector plateBl'is vpivoted at its upper end,

as at 34,' and actuated by a spring 35 so that igtslowery end engages a recess or seat in the rib or ,a/nge 28, as seen in Fig. 5.

The rake is Araised and lowered by a cable or thelike 36`o'ne end of which is attached I to and wound upon the winding drum or win'dlass 10 and the other endof which is attached to the lower end of the rake bar. The intermediate portion of said cable passes over a guide pulley 37 journaled between the inner portions ot the arms 14 andV also over a guide roller 38 arranged in a guard plate 39 which is disposedv immediately above the upper end of the lrackl 2 and is attached to the outer edge of the trough 7, as

seen in Fig. 1.

4:0 denotesfa spring arranged between the arms .la and adapted to be compressed by the rake bar as the head` of -the' latter is moved inwardly to discharge its contents into the trough 7 and also adapted to throw the rake hea-d outwardly the instant the hoisting cable is' released.

4l denotes a guard which .prevents the carriage from tilting. It islin the form` of a bracket attached to the platform 8 of the portions,

, carriage and having its lower end projecting .n

under the head ot one of the track rails 4', as` seen in F ig. 1. ,i

-In tiperation, when the carriage is placed jupon the track the boom or rake support-t) iis adjusted to properly position the plates l5 above the rake, 'a'iidqthfe bearing blocks 27 are then adjusted so that, when the rollers 2h are in the guide channels 20 the rake bar will be substantially parallel with the rack. When the parts are in the position shown in Fig. l and the drum l0 is rotated to wind the cable thereon, the rake head will be moved vertically'and the rake bar will travel in a plane parallel with the rack 2-until the rollers 26, 25 enter the portions 29, 30 of said guide' channels, whereupon the'ralre head will be swung inwardly to throw the trash upon it into lthe trough 7. When the rake bar is thusl swung it will compress the spring Zl0 so that the instant the cable is released said spring will swing kthe .rake head ontwardly and the vrake bar will be permitted to drop by gravity. As the lower end of the rake bar swings outwardly the rollers 2li are deflected by the plates 31 out of the lower ends of the channels so that they will travel upon the outer acesof the {langes or ribs .22, thereby holding the rake head away from the -rack until said rollers again enter the channels'20 at the upper ends of the lat ter. After one portion of the rack 2 has been cleaned the carriage. may be adjusted to clean another portion oi the sinne, but it will. be understood that the cleaning device may be mounted stationarywhen the rake head can be made suiiiciently broad to clean the entire rack at one o eration.
