DUMP CAR.

Application filed. December 2 4, 1925. Serial No. 77,461.

My invention relates to improvements in dump cars.

It is an object of the invention to provide means for actuating door winding mechanismthro-ugh oscillations of a lever in such a manner that the actuating means will move in unison with the winding mechanism in one direction and move independently thereof in the opposite direction.

It is also an object of this invention to provide dump door raising mechanism having locking means in conjunction with independent door latching mechanism so related to the raising mechanism, that the locking means of the raising mechanism will be automatically released upon actuation of the latching mechanism to release the door.

Other and further objects ofthe invention will more fully and clearly appear from the description and claims hereinafterfollowing.

In the drawings Figure 1 is a side elevational view of a portion of a car embodying my invention. 1 Fig. 2 is a vertical transverse sectional View through a portion of the car as shown in Fig. 1; Fig. 3 is an elevational end view of the car; Fig. 4 is a fraginentary horizontal sectional view through a portion of the car above the outer end of the door raising and lockingmechanism, the section corresponding substantially to the line 4-a of Fig. 1. Fig. 5 is a horizontal sectional view through a portion of the car above the winding actuating mechanism, and corresponding substantially to line 5 5 of Fig. 3. Fig. 6 is an enlarged fragmentary side elevational view of one end portion of the car showing the door winding mechanism and pawl locking mechanism therefor, together with the leverfor operating the latching mechanism. Fig. 7 is a vertical sectional view showing the door raising actuating mechanism in inoperative position, the section being taken on a line corresponding substantially to line 77 of Fig. 3. And

Fig. 8 is a view similar to Fig 7 but showing the door raising actuating mechanism in its operative relation with respect to the ratchet wheel.

My invention is illustrated as applied to a car having vertical sides AA, sloping end floors BB, center sill structure C, and dumping doors D D hinged to the center sill structure on the opposite sides thereof and adapted to extend outwardly to the car sides. Each side wall A includes side plate 10, top chord 11, bottom chord 12 and side stakes 13, the latterbeing preferably of Z-shape formation. The center sill strue-. ture C includes channel shaped members 14.1t'having a sin-mounting ridge 15, and; beneath the ridge are secured a number of hinge brackets as indicated at 16.

Inasmuch as the dumping doors, and mechanism therefor, on the respective sides of the car are of similar construction, the description will be confined to one sideof the car. Each dumping door is formed ofa plate member 17 flanged upwardly as at 18 beneath the sloping ridge of the center sill. Each dooris reinforced on its under side by a series of hinge beams 19 formed at their inner ends with hinge eyes 20 adapted to receive hinge pins 21, whereby thedoor is mounted upon the brackets 16. Eachdoor is reinforced longitudinally of-the car, ad jacent the rear edge thereof, by an angle member 22., and adjacent the free edge ofthe door by a beam structure formed by a Z- shaped member and angle member as indicated at 23 and 24 respectively. The hinge. beams 19 are extended outwardly ofthe free edge of the door through perforationsin the beams 23 and 24. Pivoted 0n brackets 25 fixed to the side of. the car, adjacent each. floorbeam 19, are hooks 26, the lower'ends of which are adapted to engage beneath the outer projecting ends of the floor beams 19 to support the door after it has been raised to, a substantially closed position. The hooks are each formed with an upwardextension- 126, and the series of hook extensionsalong. the; side of the car are connected by'a hori' zontal bar 27 which is adjust-ably connected at one end by a link 28 to an operating and locking lever 29 supported on the car struc: ture from a pivot disposed in fixed relation to the car structure, as indicated at 30. -Adjacent the upper end of the-lever- 29 there is provided on the car structure a bracket 31, on which is pivotallyv mounted a locking bar 32 to swing in the path of the said lever- 29 to lock the same when the supporting hooks are in. latching position beneath the door.

As the doors are of considerable weight, power multiplying raising means are pro-. vided to raise the doors to such aposition thatthe lower ends of thehooks 26may be brought into engagement with. the corree sponding floor beams 19, and the door wedged to a closed position making a tight fit with the car side. In a preferred form the raising mechanism includes two or more flexible members or chains 33 which pass over suitable pulleys 34, which are rotatably mounted, as indicated at 35, in suitable brackets 36 and 37 respectively, said brackets preferably resting on the lower chord 12 of the car side, and each of said bracketsincluding an outer vertical wall 38 through which the pulley supporting pivot 35 extends. The elements 33 are connected to the doors, and after passing over the pulleys 34, extend horizontally towards one end of the car, and are adjustably secured to a bodily movable bar 38, as indicated at The bar 38 is guided and maintained in operative relation at one end with the adjacent pulley 24 by a lip 40, which is disposed above the adjacent element 33. The bar member 38 extends through perforations in the vertical side stakes 13 and additional guides are provided as indicated at 41 and 42 respectively, the guide 41 being affixed directly to the car structure and guide 42 being formed as an integral extension of the bracket structure 37 For the purpose of moving the bar 38 longitudinally in order to raise the door a winding device, indicated at E, is provided, said device including a winding drum 43 disposed substantially in alignment with the reciprocating bar 38, and connected thereto by means of a flexible member or chain 44. (lo-operable with the drum 43, and preferably formed integrally therewith, is a ratchet wheel member 45, with which is co-operable a hook shaped locking pawl 46, said pawl 46 being mounted on a bracket 47, and formed with a weighted arm or extension 48 which extends rearwardly and has a laterally projecting lug 49 extending substantially in the plane of the door hook locking and operating lever 29. Co-operable with the said lug 49 is a hook-shaped catch 50 which is pivotally mounted on the lever 29 and formed with an abutment 150 adapt ed'to support the said catch 50 relatively to the lever 29 so that as the lever is moved rearwardly the catch will be in position to engage with the lug 49 of the said pawl 46, the end of the catch being bevelled as indicated at 151 so that the latch is automatically displaced a suflicient amount to permit a recess 152 in the catch to engage the lug 49 and lock the pawl 46 relatively to the lever 29.

The means for actuating the winding drum 43 by imparting a movement of rotation thereto is indicated at F. Said actuating mechanism is connected with the winding means E by means of a rotary shaft 51. the assembled mechanism presenting a wind less-like device journalled at one end adjacent the side of the car in a bearing bracket 52 which in turn is carried by a gusset plate 53, the opposite or inner end of said shaft being journalled in a bearing bracket 54 carried by a supporting framework includ-. ing a vertical gusset member 55, which in turn is suitably supported by port ons of the framework of the car structure as indicated. at 56 and 57 respectively. The spacing of the winding mechanism E an appreciable distance from the actuating mechanism F permits the disposition of a ladder 111 therebetween without interfering with the operation of the door operating device and also provides for safe and convenient operation from the platform 110 of the car. The actuating mechanism proper as indicated at F includes: a ratchet member 58 fixedly mounted on the shaft 51; oscillatable arms 59-59 rotatably mounted on the opposite sides of said ratchet member; a detent member 60 disposed between the arms 59-59 and pivotally mounted thereon as indicated at 61, said member 60 having a pallet 62 adapted to engage with the teeth of the ratchet member 58; connections 63-63 pivoted to the detent 60 at an appreciable distance from its pivot 61 as indicated at 64; and a lever 65 pivoted to the car structure on a fixed pivot 66 and also to the con nection 63, as indicated at 67, whereby rotation of the shaft 51 will be effected through a series of oscillations of the said lever 65 in a n'ianncr as will be described hereinafter. The pivot 66 on which lever 65 is mounted is preferably in the form of a trunnion formed integrally with a bracket 68 secured to a fixed part of the car and mounted at an appreciable distance from the operating shaft 51. Said trunnion is perforated outwardly of the lever and a pin 65) is inserted therein to retain the parts in operative relation. The lever 65 moves between guides 70 7O which maintain the lever against sidewise movement and also limit the for ward movement of the same.

The operation of the winding and actuating device is as follows: Assuming the door D to be open with the parts positioned as in Fig. 7, the operator moves the lever 65 in a clockwise direction thereby rotating the detent 60 until such. time as the pallet 62 is brought into engagement with one of the teeth of the ratchet member 58 which will induce interlocking action between the ratchet member 58, and the oscillatable members 59 (the parts then assuming the position shown in Fig. 8). For the purpose of preventing undue strain on pivot 61 stops 71 are provided on the inner face of oscillating members 59 which engage with detent 66 when pallet 62 is in full engagement with its co-operating tooth of the ratchet ,member 58, and thus limit the pivotal action of dctent 6O relatively to the members 59. The

operator then continues the movement of the lever in a clockwise direction to impart suflicient rotary movement to the shaft 51 so that the locking pawl 46 may be engagedwith the next succeeding tooth on ratchet member 58, and thereafter he reverses the movement of lever 65, moving it in anti-clockwise direction, thereby rotating detent 60 in a direction to cause pallet 62 to move away from the teeth of ratchet Wheel 58 and so permitting the oscillatablc members 59 to move independently of the ratchet wheel. Relative movement between detent 60 and link 63 is limited by laterally projecting wings 160 formed integrally with member 60 and which engage with link members 63. These oscillating operations of the lever .65 are successively repeated until such time as the door D is substantially closed, atwhich time the lever 29 operating the latches 26 is moved rearwardly until the latching hooks 26 are well beneath the door beams 19, and thereafter the lock 32 is turned into the path of the lever 29 locking the same securely into position. As lever 29 is moved rearwardly to its locking position the latch 50 in such a relation,

due to the wall 150 abutting against the edge of the lever 29, that the bevelled portion 151 will ride upon the lateral projection 49 of the locking pawl permitting suflicient movement of the catch to enable the walls of the recess 152 to interlock with the said projection 49.

Assuming that it is desired to discharge the load in the car with the parts in locked position as indicated in Fig. 6, the lock 32 is released and the lever 29 moved forwardly in a direction to move the supporting hooks 26 away from beneath the floor beams 19 of the door. As the lever 29 moves to release the door the catch .50 moves in unison therewith, thereby disengaging pawl 46 from :the .ratchet wheel member 45 so that the drum is free to rotate in an unwinding direction and the door opens due to the Weight of the lading thereon, as will be understood. In the open position the weightof the doors is supported by suitable buffers 72 and 73 which are preferably carried by the center sill structure.
