Referring now in detail toy the drawings lWhere like reference characters refer to like parts, reference character. 1 indicates a dump if?? car having a dumpb'ody2 tiltably mounted 0n an underframe 3.Y As shown in Fig. 1 of the drawings, the body is supportedfontrun'- nions 4 having a bearing 5V onth'e und-erframe 3. HOWeven-it'is tobeunderstoodthat '.3 perform its locking and unlocking movements independently of thek door closing mechanism.V Referring to the drawings, Fig. 1 is atransvarious other suitable methodsmay be enfr-V ployed for mounting the body onvtheunder-L frame.v At each side of the car body 2 are door-s6 which When closed form the side Walls of the body. rllhese doors 6 are hinged ad'- jacent the Vfloor 7 of the car body'and open outwardly afnddoWnWardly as the car body is tilted fordumping. S'paced longitudinally of the doors and secured theretoare downward depending members 8, Which are adapted to engage With the door operating mechanism and with the door locking mechanism.
Spaced longitudinally of the underframe are suitably formedd'oor operating mechanisms which control the opening and closing of the doors 6 as the body is tilted in dumping. Any suitable form of door mechanism can be used with my. invention, and l have illustrated in Fig.1'a preferred form which forms no part of my invention and is made the Subj ect of an application lfor'patentby N. S. Reeder, SerialrNo. 343,668, filed March 1, 192,9.
.The door'operating mechanism comprises a member 9 mounted on the underframe and in engagement Withthe body, a member 10 vmounted on the underframe and adapted to engage with the opening door, and a member 11 connectingwith the freeendsof the members 9 and 10 to cause the member 10.
kto be actuated by the member 9Minv engagement with the tilting car body. The contourof the end of the door-member 8- in engagement With the. Operating memberA 10 is suoli that the door is substantially closed before the body has completed `its return to a horizontal position after dumping, and in this position is; engaged by the locking meth--V longitudinal center line thereof and in en gagement with the depending doorV members 86A. 1^; `method of .mounting the. locking barsl 12to the car body 2 is illustrated .in Figs..f5 and', 6 of thedrawings. The longitudinal body 1 member `13r` lhas Openings 14 Vtherethrough in which-the bar 12 irs supported by the bearings 15, but any suitable form of bearing may be used which will serve to support the bar.
rlChe type shown in Fig. 6 comprises a twopiece bearing attached to each side of the body member 13 and having a recess in one end for the reception of the pin 16 which is mounted in the locking bar 12. At each end of the bar 12 are mounted rotatable members 17 which bear on suitably formed surfaces on the door members S-As At each side of the underframe. adjacent the door members S-A are suitablyformed bearings 18 which maintain the locking bar in position when the body is horizontal and about which the bar 12 rotates as the body is tilted for dumping.
Adjacent the bearings 18 are suitably formed portions 19 and 19-1 of the bar 12 which assist in controlling the movements of the bar 12 as the body is tilted in dumping. In cars of the type illustrated, the tilting and righting of the car body is done by body tilting cylinders mounted on the underframe and operated by compressed air supplied from any available source. These cylinders form no partof the present invention and for that reason are not illustrated here but may be of any suitable form and number.
As the car body is tilted towards the righthand side of the underframe, as illustrated in Figs. 1 and 5 of the drawings, the body rotates on its trunnions shown in Fig. 1, and by reason of the location of these trunnions moves towards tne right side of the underframe as the tilting continues; this causes the portion of the bar 12 at the left side of the body to leave the undertrame bearing 18 with the rising of that side of the body and the portion at the right side of the body to move downwardly and to the right along the member 18 on the right side of the underframe.
This movement of the bar 12 causes the portion 19-A'to move onto the bearing 18 and in turn causes the bar 12 to rotate on its pin 16 to move the left side of the bar downward and the right side upward along the depending door member 8 1@ The member 17 on the end of the bar 12 at the right side of the car moves along the surface 2O onto the surface 21 of the depending door member 8-A. The surface 21 is in the form of a depression in the member S-A and allows the bar 12 and bearing 17 to move into the member 8-A when the door 6 opens downward by the force of gravity and the weight of the lading in the car body. With the tilting ot the car body the door member 8 engages with the member 10 of the door mechanism which controls the door during the subsequent movements of the body until the final dumping position is attained. The locking bar 12 during these movements of the body continues to rest on the bearing 18 and has'its end bearvside doors hinged adjacent the floor of said ing 17 within the depression 21 of the door member Snr-1 which is deep enough to receive that member during all opening movements of the door. An additional depression 22 adjacent the surfaces 2O and 21 in the door member 8-A allows the door to clear the bar 12 when in fully opened position. This final dumping position of the car body and relation of the bar 12 to the door member 8- is shown in dot and dash lines on Fig. 5 of the drawings and the rela-tion of the door operating mechanism to the door member S-A is shown on the right side of Fig. 1 of the drawings.l
l/Vhen the car body is returning` to a horizontal position the door operating mechanism moves the door towards substantially closed position and before the body has reached a position horizontal with the underframe. The door locking bar 12 during tnis return of the body moves along the bearing 18 and the end bearing 17 moves out of the .depression 21, with a consequent rotation Vof the bar on its bearing 16 to bring the end bearing 17 onto the surface 20 of the door member S-in The end bearing 17 reaches the .surface 2O ol the door member 8-A simultaneously with or a little before the door operating mechanism has returned the door to a substantially closed position and before the car body has completed its return to a horizontal position.
The door locking barfis now in Contact with both depending door members 8-A and as the body completes its return to a horizontal position the bar nally closes and lool-rs the doors, and the final return movement of the body moves the door member 8 free of the door operating mechanism.
