Referring to the drawings in particular, the invention as embodied therein includes a service-type railway car generally designated 10 having an underframe 12 upon which a body 14 is supported. The body 14 has a conguration simulating that of an authentic track cleaning car.
The underside of the frame =12 is providedy with suitable bearing means at each end to rotatably support a forward set of wheels 16 at one end and a rear set 1'8 at the opposite end. In this instance, the car 10 is made Without a self-propelling motor and it is normally pushed along the track in front of a locomotive or engine car. In some instances, however, it may be desirable to provide a self-contained driving means for the wheels of the car.
The body 14 is opened at the top forward portion and is provided with curved supporting recesses 20 and 22, shaped to hold therein a pair of cylindrical liquid containers 24 and 26 respectively (FIG. 5). The liquid containers 2liand 26 V(FIG. 9) hold a reserve supply of either a washing or cleaning liquid such as wat-er, liquid soap, solvent cleaner, etc., or they may contain a lubricating oil. Each container is provided with a discharge nipple L28 having a suitable opening through which the liquid may be poured. The discharge nipple 28 is covered and protected by a screw cap 30.
The after portion of the body 14 is built up to define an inner motor chamber 32 having a horizontal platform 34 on which is mounted an electrical motor 36. The car 10 is usually operated by placing the sets of wheels 16 and 18 in position on a set of parallel guiding outer tracks 38. The tracks are constructed with an inner third rail or power supplying track 40'. Energy is supplied Ito the motor 36 through a roller contact 42 ar range at the end of an arm 44, pivotally mounted on the underside of the frame 12 and biased by a spring 46 in a direction urging the roller 42 into contact with the third rail 4d. The pivot arm 44 is connected electrically through a switch 48 to the motor 36. The switch `41 has a long handle which extends through an opening in the frame 14 to permit the making and breaking of electrical contact by moving the end of the handle.
In accordance with the invention the central portion of the underframe 12 has a cylindrical bearing portion 50 dening a bearing mount for a track cleaning or oil dispensing assembly generally designated 52. The cleaning or dispensing member assembly 52l includes a drivingv sleeve generally designated 54. The sleeve 54 includes a large diameter upper portion 56 and a small diameter lower portion 58, the latter being rotatably mounted in the sleeve portion 50 of the underframe 12,. The lower outer annular surface `of the portion 56 bears against the upper surface of the underframe 12 during rotation of the assembly 52.
The driving sleeve 54 is provided with a gear 60 which extends outwardly from the lower end of the large diameter sleeve portion 56 and is rotated through two sets of reduction gears 62 and 64 by the electric motor 36 driving through a small gear 66 mounted on the motor driving shaft 68.
The cleaning or dispensing member assembly 52 also includes a liquid applying element 70, preferably of a resilient, absorbent material such as a foam, plastic or rubber-sponge, which is atxed to a metal disc 72 as by adhesively sealing thereto. The metal disc 72 is provided with a central cylindrical opening 74 and a set of diametrically opposed rectangular openings 76, positioned to receive an intermediate driving and `oil distributing member generally designated 78.
The driving and oil distributing member 78 includes an upstanding cylindrical post 80 terminating in a spherical head 82. The cylindrical post is cut away at the lower end` to define a passage 84 to facilitate liquid flow therethrough. The post 30 is provided with laterally extending spline projections 86 which fit into spline-like grooves in the lower small diameter portion 58 to lock the parts for rotation together. Then post 80 with the spline projections 86 is mounted in the center of a at disc 88. A pair of resilient latch elements 90 are arranged at diametrically opposite sides of the disc 88, and normally fit into the rectangular openings 76 on the disc 72 to lock the parts together. A set of spacers 90 are provided on the disc 88 to hold the disc 88 a distance below disc 72.
The intermediate driving and oil distributing member 78 is connected to the liquid applying element 70 by inserting the post 80 through the opening 74 and the latched members 90 through the openings 76 (see FIG. 8). These two groups of elements are then positioned in the driving sleeve 54 by aligning the spline projections 86 with the grooves in the small diameter sleeve portion 58. A resilient frusto-conical open-topped holding shoulder 92 is affixed to the inside of the large diameter sleeve 56. The spherical head 82 of the post 80 may be pressed through the top of the shoulder 92 and is retained thereabove during rotation `of the assembly S2. The intermediate driving member may be removed by pulling the spherical head 82 through the opening in the shoulder 92.
The body 14 is provided with a cylindrical liquid filling chamber 94 arranged in vertical alignment with the track cleaning and oil dispensing member assembly 52. The cylindrical slot 94 is provided with an opening 95 at the bottom end made large enough to permit the dripping of liquid therethrough into the driving sleeve assembly 54. The liquid thus received ilows in the direction of the arrows (FIGS. 3 and 7) downwardly around the post 80 and in on top of the disc 88, where it is distributed by centrifugal and gravitational action to the absorber element 70.
In accordance with the invention the car is provided with an additional track cleaning or wiping mechanism to supplement the action of the rotating liquid absorbent element 70. To this end, a mounting bracket 96 is affixed to the underside of the frame 12 at the rear end thereof. The mounting bracket 96 is provided with suitable L- shaped bearing surfaces 98 on which is pivotally mounted an auxiliary cleaning carriage generally designated 100. The auxiliary cleaning carriage 100 is provided with a pair of spaced side frame members 102 having stub shafts 103 which project inwardly therefrom and are pivoted on the L-shaped bearing surfaces 98. One end of the side frame members 102 is provided with a pair of inwardly extending lateral stops 104 which are effective to contact the mounting bracket 96 and limit the upward movement of this end of the frame members and the downward movement of the opposite end.
The frame members 102 support an inverted U-shaped mounting member 106 which extends outwardly to the rear of the car. Mounting member 106 is provided with a cylindrical slot 10S in which is loosely positioned a universal supporting bolt 110. The bolt is of a diameter small enough to permit free movement in the slot 108, but is provided with a head large enough to prevent it from falling therethrough.
A substantially dipper-shaped open-ended Wiper and wheel piece generally designated 112 is provided with a.
cylindrical slot in the top of an open-ended inverted U- shaped portion 114 through which the bolt 110 is loosely fitted. The bolt 110 is provided with a lower flange 116 which prevents disengagement of the member 112 therefrom. The complete carrier and wiper member 112 pivots freely about the bolt 110 in a manner similar to a universal joint. The U-shaped portion 114 s packed with an absorbent material 118 such as cotton, cloth, tape or the like which projects downwardly beyond the side edges thereof. In some instances, it may be desirable to place a sheet of an abrasive material such as sandpaper over the abosrbent material 118 in order to clean the" track of gritty substances, if desired.
The rear end of the member 112 is provided with suitable bearings to rotatably mount a pair of guiding wheels 120. A tension spring 122 is aiiixed to a depending portion of the bracket 96 at its one end, and to the lower forward edge of the mounting member 106. The frame members 102 may be rotated about their L-shaped bearing surfaces or L-shaped pivot surfaces `98 to permit the movement of the aft auxiliary cleaning carriage 100 to the position indicated in FIG. 4, in which instance the spring 122 will act to bias it in this position. When the aft auxiliary cleaning carriage 100 is brought downwardly into an operative position, with the wheels in engagement with the tracks (FIG. l), the spring will again act to bias the carriage in a direction toward the tracks. Thus, it is seen that the pivot at the L-shaped bearing surfaces 98 and the spring location is such that the spring will urge the carriage 100 into the position indicated in FIG. 4 when it is initially moved manually slightly above the horizontal and it will urge it into a track engaging position similar to FIG. 1 when it is initially moved manually slightly below the horizontal.
ln accordance with another aspect of the invention, the forward end of the lower frame 12 is notched at each side of the center line to provide holding recesses 124 and 126 to confine each end of a leaf spring 128. The leaf spring 128 is made in one piece of resilient metal which is coiled around a central vertical pivotal bolt 130 held in the frame 12. Also pivotally mounted on the same bolt 130 is a self-aligning coupling 132. The coupling is substantially rectangular and is provided with a forward recessed mating end 134 suitably contoured to mate and hold with a male coupling. It is provided with cylindrically shaped rear corners 136 and 138 arranged in contact with spring 128. The coupling 132 is self-aligning, and any tendency to misalign it, as `by moving it from the left or to the right, will be overcome by the force of the spring 128.
T o operate the car 10 in accordance with the invention, a quantity of cleaning or oiling liquid is poured from one of either of the cylinders 24 or 26 into the reservoir slot 94. The liquid flows by gravity through the opening 9S into the driving sleeve 54, from whence it passes around the post 80 to the surface of the disc 88, from whence it is distributed to the absorbent element 70. The train is positioned on the tracks and is pushed or pulled by a locomotive or similar power driven car attached to the coupling 132. The switch 48 is closed and current is effective to operate the motor 36 to continuously rotate the complete track cleaning or oil dispensing member assembly 52.
It is preferable to apply cleaning fluid or oil to the tracks when the aft auxiliary cleaning carriage is in a position out of operational engagement with the tracks (FIG. 4). After the oil or cleaning tiuid has been applied, the motor 36 may be switched off and the disc 88 with the absorbent element 70, and the intermediate driving and liquid distributing member 78 may be removed from the sleeve driving element 54. The absorbent member 70 may be removed from the remainder of the parts and replaced or cleaned. lf desired, the auxiliary cleaning unit 100 may be placed in an operative position (FIG. l) to clean the tracks with the absorbent element 70 removed and the motor 36 disconnected, or both the cleaning unit 100 and the absorbent element 70 may be operated simultaneously. i
While a specific embodiment of the invention has `been shown and described in detail to illustrate the application of the invention principles, it may be understood that the invention may be embodied otherwise without departing from such princip-les.
