Specification of Letters Patent. Application filed July *7, 1909. Serial No. 506,335.

To all whom, it may concern:

Be 1t known that I, FREDERICK SEABERG,

' a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specification.

The object of my invention is to provide an improved operating mechanism for the doors of dump cars.

It is more especially designed for use in" ,the type ofcars known as ore cars, n which i the end walls of the car slope downwardly toward the middle f the cars length where the dump doors are situated. f

My improvements relate particularly 'to ore cars which discharge their load centrally between the rails, and in which there are two.cloors hinged near the outer edgesof the Y load, no strain occurs in the chain and operating mechanism. I

-Other objects will be made apparent in the following'description and claims, taken in connection wlth the accompanvmg draw- 'with m improvements applied thereto.

In the drawings, usual sloping end walls 11 which terminate Fig; 5

' at the bottom of the car near its center in the vertical walls 12. The side walls '13 are provided with an inwardly sloping sheet producing a converging effect- 11 which serves as a strengthening member for the! frame and also as a means for in the lower 'i'iiteriorppait' of the car body. The sloping sheets 11 terminate 111 a vertical portion 15 and bars 21.

their lowermost extremity.

The side-sheets 13 are attached at their lower edgesto. the'side' sills .17 A strengthening sheet 18 is interposed between the sheet 14 and the side sill 17 The angle bar 19 is fixed to the sheet 18. A small'sheet '20'of irregular outline is attached to the angle bar 19 and serves as a means of attachment for the guide bar 21. The oppothe vertical wall 12 near the center of the 'site end of the guide bar 21 is attached to car. This completes a brief description of the car yframe'to which my improvements are attached.

The dump doors 22 are made of rectangular form, preferably of steel, with strengthening ribs 23 fixed to their under surfaces. The doors-are provided with hinges 24 by which they are pivoted to a fixed hinge piece 25 on the car body- A pin 26joins the two hinged parts. The, two doors 22 swing outwardly' to dump the. load and their lower and inner edges come together at the center when closed. i

The doors 22 are operated in their closing movements by movable members 27, which are preferably hollow shafts, and may be made of heavy iron pipe. They bear upon the under surfaces of the ribs 23 and slide inwardly and outwardly under said ribs.

They are supported by the sloping guide bars 21 and slide upon said bars in their door operating movements. They are placed in a position at right angles to the ribs 23 The weight of the doors 22 and of the contents of the car .which rest upon them is transmitted through said ribs 23 to said members or shafts 27 and by them the load istransferred to the guide bars 21.

The relative positions and slopes of the doors 22 and of the bars 21 enable the members or shafts 27 to close the doors when the said shafts 27 are pushed inwardly or toward the center of the car. The inward mrywementof the shafts 27' is effected by links 28, 29, 28 and 29* which areconnected One of the shaft segmental sheave 31 having a "pivotal i connection'at each end of said link. The er shaft 2"?" is connected at one end to another sheave segment 30 by'the link 29 having a, pivotal connection at each end.

The other shaft 27 is also connected opposite end to that described above to not-her arm 31 with a pivotal pin conn at. each end of link 29". The arms l 31*" ed to the shaft and are y di posed thereon. 'Tl'iey are fixed nd of said shaft opposite to that the segmental sheaves 3G and 3,1 The pin connections 38 and 31 in opposite dlftlflO'L'I'Etl relation the axis-of the shaft-32L he shafts 2' is connected to the and the arm 30 both of which its side of the shaft 32. Any nee; of said shaft 32 will therefore .af-

The. other .4 is simiiarly connected to the shaft of the segmental sheave 31 and l 'i on the same side of shaft t segmcntal sheave 30 and my rotative movement of the lie seen to cause movements of $31 and said movements will be or away from the center of inner extremities of the movements nei'nhi or shafts 27, when they slide he upper surfaces of the guide bars 3 parts of said surfaces which have a o erent slope. This different slope is such to prevent a tendency of the shafts 27 to slide hack down the inclined bars and thus allow "he doors to open. When a shaft 27 is ting upon this part of the guide bar, the st. tin caused by the load is removed from all of door operating mechanism, except the shaft 27'.

The links 29 and 29 are given an upward as hand. at 29 topermit them to clear the ends of the links 23 and 28 The links 28 and 23" and 29 and 29* lie outside of the guide bars 21, and theends or eyes 28, 29, & c., serve to prevent the shafts 27 becoming displaced from their proper positions on the U .Lidc bars 21. I

The shaft 32 is supported 1n bearings 33 iixed to the guide bars 21. The shaft 32 project s a considerable distancev be nd the bearings 33, and the segmental s eaves 30 Gne of the shafts 527 is also conboth ends the shaft E27 similarly and and 31 are mounted on said shaft at its extreme. end, and in a position outside the links 29, 28, 810., and the other parts of the mechanism. The arms 30" and 31 are also placed at the extremity of the shaft 32 at its other end and lie outside the other parts of the mechanism. This arrangement prevents interference of the parts and permits a very advantageous disposal of them for the purpose-desired.

The segmental sheaves 30 and 31 are adapted to receive the chain 34' in their grooves. One end 35 of the chain 34 is fixed to the segmental sheave 30 by means of an eye bolt 36 which is placed in a hole 37 in the bottom of the groove, A. small part of thechain 34 is wound upon the segmental sheave 30 when the doors are closed, as shown in Fig. 2. The relative positions of the chain and the segmental sheave 30 when the doors are open are shown in Fig. 5. The

other end of the chain 34 is fixed to the segmental sheave 31 by the U-shaped, link or clevis 33 and pin 39. The segmental sheave 31 occupies a larger part of the circle of which it is a segmentthan' is occupied by the segmental sheave 30, for the reason that its angular relation to the chain requires it. The end of the chain is given a turn around the end or corner 40 of the sheave rim, before it is fastened thereto, in order to give greater security to said fastening and also to permit as extensive contact as possible of the chain in the groove.

The chain 34 is wound aroundthe drum at about the middle of the length of said chain. The drum 41 is preferably provided with a helical groove 42. into which the chain is wound. The drum 41 is fixed upon the shaft 43, supported at one end by a hearing 44 carried by a bracket 45 fixed to the car body. At the other end the shaft 43 is suitably supported by the bearing 46 fixed to the car frame. A hand lever 47 is loosely mounted on said shaft 43 at its outer end,

and is adapted to actuate the said shaft by means 'of a ratchet wheel 48 and pawl 49. A. detent wheel 50 and detent 51 are provided for preventing a back movement while lever 47 is taking a return stroke. The detent 51 is s pported by a pin 52 when not engaged \Vll'ililjhe detent wheel 50.

In operatingy invention to dump theload, the lever 7 is given an oscillatory movement by t e operator, the detent 51 having been first turned back upon the pin 52 and out of engagementwith wheel 50. The pawl. 49 is placed in engagementwith the wheel 48 in such manner that a lefthand movement of the lever 47 will move the ratchet wheels and the shaft-'43 to the left, as viewed in Fig. 2. This movement will be transmitted by the shaft 43 to the winding drum 41, and the chain 34 Wlll be caused to exert a; pull uponthe segmental in Figs. 2, it

messes 28* will be pulled to the right, and they Will cause the other shaft 27 to, be moved outvardly and upon th'e sloping portion of its guide bar 21. Little or no effort is now needed on the part of the operator with the hand lever 4?, to cause the shafts 2? to slide down the guide bars 21 and the doors to open Widely. To close the doors, the operator first reverses the pawl -19 and swings the detent 51 into engagement- With the ratchet wheel 50. The lever 47 is then given an oscillatory movement and the shaft 43 is rotated in the opposite direction, was

ing the drum 4:1 to exert a pull upon the lower part of the chain 3 L The pull of the chain thus effected is transmitted to the segmental sheaye3l. This causes a reversal of the movements above described,

and the shafts 27 are moved inwardly and upwardly along the sloping guide bars 21, piishing the doors 22 to a closed position.-
