- chassis 251 may all be integrally formed of plastic, say by injection molding, or other wise fabricated of any suitable material.
- An elongate, upper carrier part or body is generally designated d5 and is superposed in spaced relation over the chassis M.
- the body 5 is illustrated herein as of a flattop type, but may be of other design, such as a gondola or otherwise.
- the body d5 may be provided on one side with upstanding posts or stakes as fixed in position, and provided on the other side with a barrier d7 including a longitudinally extending side rail db and a'plurality of longitudinally spaced posts 49 upstanding from the side rail.
- the side rail #58 of the barrier 457 is pivotally connected to the platform of the body 45, as by a pair of longitudinally spaced, axially aligned hinges 50 on the underside of the body.
- barrier 47 By this hinged connection of barrier 47 to body 45, the barrier is swingable between the solid line upstanding position of FIGS. 3, ll, a and '7, to the outwardly and downwardly swung phantom position of FIGS. d, 6 and 7.
- the barrier 47 is provided with a pair of depending fingers or the follower elements 511, each having a suitable configuration, as at 52 in FIG. 7, for following engagement with a respective cam 36.
- the barrier 47 is maintained upright in the solid line horizontal position of body 45, and released for downward and outward. swinging movement in the inclined, phantom position of the body.
- the body For movement of the body 35 between its solid line and phantom positions, the body is mounted on the chassis 31 by means of a pair of spaced pivotal connections 55. That is, the pivotal connections or hinges 55 are located longitudinally at opposite ends of the recess 37, intermediate the chassis 3i and body 45, the hinges being in alignment with each other longitudinally of the chassis and body, and slightly offset from the longitudinal center line thereof toward one side of the chassis, as best seen in H68. 4, and 6.
- the body By this pivotal connection between body and chassis, the body is swin gable from the solid line horizontal position toward one sideof the chassis to the course, the body 45 and barrier are swingable to return from the phantom position to the solid line position.
- the body 45 In the absence of load on the body 45, the body is normally urged to its horizontal position by the upper ends of springs 44 in resilient bearing engagement with the underside of the body at a position offset laterally from the pivotal axis of the body. The presence of a load on the body-45 further assures the maintenance of the body in its solid linehorizontal or loadcarrying position.
- the electromagnet 60 may be of a horseshoe or U-shapcd configuration, disposed generally horizontally within the receptacle 37, having its bite region 61 adjacent to the housing 39, and its legs 62 extending laterally toward and terminating in the cutout 38 of the receptacle 37.
- the electromagnet 60 may include electric coils 63 on each leg 62, and the receptacle 37 may have its cutout 38 further cut out or notched at 64 beneath the space between the legs 62.
- end regions of legs 62 define poles of the magnet 61, across which magnetic flux is developed upon energization of the electromagnet.
- .coils 63 may be connected by conductors 65 to pins or conin FIGS. 4, 6 and 7, the armature 69 is moved further into the interpole space between legs 62, to more completely occupy the space and cutmore lines of magnetic flux. Hence, upon energization of the electromagnet 60, the armature 69 is caused to move downwardly to more fully occupy the interpole space,'and this effects upward swinging movement of the body 45 to cause dumping or discharging of a load on the body, as by rolling or sliding across the downwardly swung barrier 47. Any such dumped load may be collected in the load receiver 25.
- the support 24 is best seen in FIGS. 9-11, as including a housing 70 having an upstanding wall 71 facingtoward a car at the discharge station, and an inner upstanding wall 72 on the side of wall 71 remote from the car 20.
- the wall 71 is formed with a pair of horizontally extending, vertically spaced through openings or holes 73 being longitudinally coextensive and one over the other.
- a plurality of longitudinally extending, generally horizontal and lateral projecting ribs 74, 75 and 76 are formed on the wall 71, the lowermost rib 74 being immediately beneath the lower opening 73, the next upper rib 75 being immediately above the uppermost opening 73.
- the wall 71 is provided with inturned flanges or lugs 77 at opposite ends of each opening 73, which lugs project toward and terminate short of the inner wall 72.
- An upper, resilient conductor strip 78 is interposed between the upper rib 76 and intermediate rib 75, extending along the upper opening 73 and has its opposite end portions curled or bent, as at 79 loosely around respective lugs 77, the intermediate strip portion 80 extending outwardly through the upper opening 73. in this manner, the conductor strip 78 is resiliently and yieldably maintained in position.
- a similar resilient conductor strip 81 extends between the intermediate rib 75 and lower rib 74, being located in the lower opening 73 and similarly yieldably held in position.
- Fixed interiorly of the support 24, as on the face of wall 72 are a pair of conductors 82, connected to respective conductors 28, for communication with a source of electric power.
- the strips 78 and 81 are cngageable with respective conductors 82 upon depression of the resilient strips, as by contact pins 66 and 67.
- the upper. lug 40 on housing 39 effectively guides the car in proper position, riding on or above the upper rib 76 and serving to locate the upper contact 66 in bearing engagement with the upper conductor strip 78, and the lower contact pin 67 in bearing engagement with the lower conductor strip 81. In such bearing engagement, the conductor strips are maintained in contact with conductors 82, so that depres sion of switch button 27 closes the electromagnet 60 to a source of electrical power.
- the switch 26 is advantageously of the momentary type.
- the present invention provides a railroad dumping car assembly which fully accomplishes its intended objects and is well adapted to meet practical conditions of manufacture, distribution and use.
