7 Claims. (Cl. 15--55) This invention relates to a deector assembly for railroad track sweepers and more particularly to a deector assembly mounted forwardly of a rotary broom in a railroad track sweeper.

Heretofore, in the use of rotary brooms for sweeping or cleaning loose material from between the rails of a railroad track, one or more transverse conveyors have been provided adjacent the rotary broom for transporting the loose materials swept up by the broom from between the rails to a position -outwardly of the rails. The present invention provides a deector assembly forwardly of the rotary broom which deflects ballast swept up by the rotary broom from between the rails outwardly therefrom and thereby obviates the necessity for transverse conveyors or other means for carrying the loose ballast from between the rails.

, It is an object of the present invention to provide in a railroad track sweeper a ballast deector assembly forwardly of and directly adjacent a rotary broom which assembly comprises a plurality of substantially vertical deectors inclined to the direction of movement of the track sweeper whereby ballast is thrown by the rotary broom against the inclined detiectors and deected outwardly of the track.

It is a further object of the present invention to provide a broom frame for the rotary broom which frame is movable vertically in relation to the track and to mount a deflector frame on the broom frame, whereby vertical movement of the broom frame raises the deector frame.

An additional object of my invention is to provide a detachable ballast sweeper unit for a railroad vehicle which unit comprises a broom frame adapted for vertical movement and a deliector frame pivotally mounted on the broom frame, the broom frame having a rotary broom mounted thereon and the deliector framel having a plurality of substantially vertical deectors thereon. Further, the power means for driving the rotary broom is mounted on the broom frame whereby the unit may be easily attached t-o the rear or front of a railroad vehicle.

Apparatus embodying features of my invention is illustrated in the accompanying drawings forming a part of this application, in which:

Fig. 1 is a side elevational view of the present inven tion showing my invention attached to an end of a railway vehicle with only a portion of the railway vehicle shown;

Fig. 7 is a view taken generally along line 7 7 of Fig. 3 and shows a stop for limiting downward movement of the detachable unit; and

Fig. 8 is a side elevational view of the stop taken generally along line 8 8 of Fig. 7.

Referring now in detail to the drawings for a better understanding of my invention, I show iu Fig. 1 a portion of a railway vehicle indicated generally by the numeral 10. Flanged wheels 12 are provided on the vehicle 10 for riding on the rails 13 supported on the crossties 14. My improved track sweeper is mounted on the rear of vehicle 10, it being understood that the track sweeper comprising the present invention may be used on either end of vehicle 10 and on many types of railway vehicles, not being limited to use with a specific type of railway vehicle. My improved sweeper is indicated generally by the numeral 16 and is mounted at the top of vehicle 10 through overhanging arms 17 secured to the top body portion of vehicle 10 and to the sweeper. The bottom portion of the track sweeper 16 is mounted on vehicle 10 through blocks 13 (see Fig. 4 also) that are bolted to across-beam 19 on the railway vehicle 10. Lower transverse frame members 20 connect the blocks 18 and

upper beams

22 and 23 has upper and

lower brackets

24 and 26,

respectively, each bracket comprising a pair of spaced arms. Rollers 27 are mounted between the spaced arms of the

brackets

24 and 26 on axles 28 extending between the arms of the brackets and ride on the vertical beams 21. Cross channel members 29 connect

vertical beams

22 and 23 on the movable frame to each other. Hy-

draulic cylinders 31 and 32 are connected to a lower transverse member 20 extending between the vertical beams 21. Piston

rods

34 and 36 of the cylinders 31 and 32 respectively, are pivotally connected yto the upper channel member 29. Thus, upon actuation of cylinders 31 and 32, the broom frameV moves relative to the vertical beams 21 secured on the vehicle 10. Cylinders 31 and 32 are controlled from the vehicle 10 through suitable controls indicated generally at 35.

Adjustable stops comprising a pair of angles bolted to the web of the vertical beams 21 are provided for limiting the downward movement of the broom frame on the beams 21. The pressure and load are thus Vremoved from the hydraulic cylinders 31 and 32 when the broom frame is brought downwardly to working position.

As shown in Figs. 7 and 8, angles 37 and 33 are bolted the vertical beams 21 to vary the height of

angles

37 and 38 on the beams 21 and thereby vary the height of the broom frame above the rails 13.

In the event it is desired to secure the broom frame in' xed raised position above the stops, chains 42 areconv nected to the top portion of beams 21. See Figs. 1 through 4. A laterally extending support angle 43 is profvided on brackets 24 and the laterally extending ange of agences Thus, upon thehbroom: frame being raised by hydraulic' cylinders 31 and 32, the chains 42rcan bejengagedl by the slotted openings i4 and the load released from the cylinders 31 and 32, the weight of the broomframe being carried by the chains 452.

A broom housing 46is connected to the

vertical beams

22 and 23 through suitable frame members. As shown in Fig. 2,

slots

47 and 48 extend downwardly in housing 46 at the portion thereof over the rails 13 for a. purpose to be explained in detail later. A rotary broom indicated generally by the numeral 51 is mounted in housing 46 on shaft 52 extending transversely of the rails 13 for substantially the entire length ofthe housing 46. The rotary broom 51 is divided into three sections, a center section 53 mounted between the rails 13 and an end section Sli mounted outwardly/.of each of the rails 13. The portion of the rotary broom 51 that is directed adjacent the rails i3 is provided with circular discs 56 for riding alongside the rails i3. The discs 56 are mounted for rotation with the shaft 52 and are fixed thereto. Suitable brushes 57 are arranged on the rotary broom and are preferabiy formed of heavy flexible steel cables.

in Fig. 2, they means for operating the rotary broom 51 are shown as comprising a gasoline engine 58 mounted on the broom frame and having a drive shaft ,extending therefrom to a gear reduction box 61. provided for controlling a clutch for the engine. A counter-shaft 64 is mounted between the gear reduction iand sprocket 66 on one end of the broom housing 46. A second sprocket 67 is secured to the broom shaft S2 and is connected to sprocket 66 through the sprocket chain 65. Thus, the drive means for the rotary `broom is mounted entirely on the broom frame.

Itis understood that in working position, the broom engages ballast and other materials lying between and alongside the rails and propels the same tothe right as viewed in Fig. l. In order that the material swept up from the broom may be deposited laterally of the rails 13, my improved deflector is provided for deflecting the materials laterally from the center of the trackto a Aposition outwardly of the rails 13. The means for deflecting the material comprises a deliector frame 71 having a pair of

arms

72, and 73 extending rearwardly therefrom through the

slots

47 and 48, respectively, in the broom housing 46.

Arms

72 and 73 are pivotally connected to' the broom housing 46 by brackets 74 on housing y46 (see Fig. 3). Thus, deector frame 71 is pivotally mounted for movement relative to the broom frame by the

arms

72 and 73 that the deector frame may be adjusted in height relative to the broom frame.

The deflector frame 71 comprises a pair of spaced angles 76 and 77 extending transversely of the rails 13 and connected at their ends by angles 78 and '79. A plurality of deliector support angles 81 and 82 is secured between the angles 76 and 77, the angles 81 being inclined outwardly from the center of the track on one half of the detiector frame and the angles 82 being inclined outwardly from the center of the track on the other half of the deflector frame. Angles 81 and 82 have downwardly extending

inclined defiector plates

83 and 84, respectively, secured thereto and arranged directly adjacent the rotary broom S1 on thematerial discharge side thereof. The

deflectors

83 and 84 extend across the length of the dellector frame 71 and are preferably formed of steel plates arranged at approximately 45 to the direction of travel of the track sweeper. Deectors arranged between 36 and 60 to the direction of travel have been found to work effectively. As shownk in Fig. 2, there is a very slight overlap between the paths of adjacent deector plates except orthe two center plates.

A lever 65 isY cut out portions 86 for receiving the rails, thereby allowing all the deflectors 83 and S4 to extend downwardly below the top surface of the rails 13. The top portion of the deliector frames 71 between the angles 76 and 77 is covered by a top plate 87 and the front end of the deiiector frame 71 is partially covered by a pivotally mounted front plate 88 extending along the entire lengthy-of the delector frame 71. An adjustable end plate 89 is pivotally mounted on each end of the dellector frame 71 through pins 91. The end plates 89 are adjustable through slots $2 which receive pins 93. Suitable liexible material, such as a rubber composition, indicated generally by the numeral 96, is secured to the bottom edge of the front plate 88 and the end plates 89 so as to form a hood or cover around the dcflector frame 71 and defllect materials from the deflectors downwardly.

in order to support the deflector frame 71 when in working position, rollers 97 are arranged on the front end of the delieotor frame for riding on the rails 13. Rollers 97 are mounted on legs 98 extending downwardly on the forward end of

arms

72 and 73. Brackets 99 are secured to the legs $8 through suitable connections, such as bolts 101. In order to adjust the height of the deector frame 71 relative to the rails 13 to accommodate rails of different heights, spaced apertures 102 (see Figs. 5 and 6) are provided in leg and bracket 99. tically adjustable on the legs 98. When the detachable track sweeper is not in working position, the rollers 97 are raised out of contact with the rails.

Adjustable supports M3 are arranged on my detachable rairoad track sweeper to support the sweeper it' it' is removed from the railway vehicle 10. A foot portion" 104 (see Fig. l) is adapted for resting on the ground or other supporting surface upon detachment of the sweeper from the vehicle it?.

In operation, the rotary broom S1 sweeps up the ballast and other material from between and alongside the rails and throws the same from beneath the broom against the deffectors 83 and 84. The ballast thus strikes the surfaces of the angularly directed deiiectors'SS and 84 and is deflected outwardly from the center of the track where it falls on the roadbed. Any material which is not thrown to the sides of the roadbed is swept up a second time and thrown again against the next outer deectors 83 and 84. It is evident then that material lying bctween the rails 13 maybe swept up and deliected several times before it reaches the last deflector on the end of the deflector frarne71. Upon reaching the last deector, the material is windrowed along the side of the track.

From the foregoing, it will be seen that I have devised a detachable railway track sweeper provided for attachment to a' railway vehicle and comprising a rotary broom and a deector unit mounted adjacent the rotary broom for deecting ballast and other material outwardly of the rails. The deflectors are inclined outwardly from the center of the railroad track and the ballast is picked up by the broom and propelled against the deectors and by them deflected outwardly. The deector unit is pivotally mounted. on therotary broom frame and may be adjusted in height relative to the rotary broom through adjustable wheels. Drive means for the rotary. broom is provided on the broom frame, thus not requiring additional drive means from the railway vehicle. The rotary broom and the deflector unit are both movable vertically on a iixed frame secured to the railway vehiclev 10 and may be raised vertically from working position. Thev de-A ector assembly of the present invention effectively transfers ballast and other materials from the center ofl the' Thedecctor plates extending over `the rails 13 have 15 equal facility be mounted on the front thereof, it being Rollers 97 thus are ver-v understood that the deector leads the sweeper in the movement of the vehicle.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.
