, JOHN NEIKIRK, OF MORGAN PARK, ILLINOIS, ASSIGNORTO RODGER BALLAST CAR CQMPANY, A CORPORATION OF MAINE.

DUMP-CAR.

T 0 all'whom it may concern:

Be it known that citizen of the United States.

residing at Morgan Park,

in the county of Cook and Specification of Letters Patent. Application filed November 12, 1908.

I, JOHN O. NEIKIRK, a

State of Illinois, have invented certain new i and useful Improvements inDump Cars, of

which the following is a specification.

My invention consists in improvements in working cars of the kind used in making railroad fills, ballasting tracks, &c.

In the drawingsFigure 1 is a transverse.

section of a car equipped with my invention. Flg. 2 1s a longitudinal section of one end of ..the car. Fig. 3 is a plan view of part of the car. i is an end view, and Fig. 5 is a plan view of part of the .underframe.

In myimproved car the load between the bolsters l is carried by longitudinal t-russed girders 2 located intermediate the center of the car and the sides thereof, thus leaving an open central space and open side spaces free from longitudinal framing. The sides of the car are supported upon cross members 3 extending outwardly from the girders and secured-thereto. The car may also be braced by transverse member-s4: extending across the open central space between the members 3. The space between the girders 2 and the bolsters 1 is occupied by the central hopper, which in the present instance comprises a stationary side 5 an? a dump door 6 hinged at its upper edge 0 a plate 7 projecting downwardly and inwardly from the upper edge of the girder on the left side of the car, as viewed in Fig. 1. The stationary side 5 is further supported by tie rods 8 secured at their upper ends to the cross members 4. The lower edge of the stationary side 5 is strengthened by a cleat 9, and a Z-bar 1Q of 'the vertical sides 12. Floor sections 13 are pivoted, 'asshown at 15 (Fig. 2), along the upper edge of the girders 2, the upper edge of said girders, -preferably, being protected .byfl'o'or :strips 16. The ends ofthe fi'o'or sections 13 are inclined as shown .in Fig. 2 .:and thereby adapted to .fit closely against the inclined -ends .11, whether said 5 1n the form of an A Patented May 21, 1912. Serial No. 462,288.

floor sections 13 are turned inwardlv to meet at the center of the car or outwardlv toward the sides of the car. Vhen the floor sections 13 are turned inwardly their beveled freeedges contact with each other, thus causing said sections to support each other at the center of the car.

,When .in this position these sections may further be supported by means of blocks 17 fixed to the inclined ends, as shown in Fig. 3.

The car illustrated is provided with ledges 19 projecting downwardly from the sides of the car and supported upon brackets 20 fixed to the vertical sides. These brackets project beyond the inclined ledges 19 to form stops against which the outer edges of the floor sections 13 may rest when said sections are outwardly inclined.

Filling the space between the girders 2 and the sides of the car are dump doors 21, said doors being adjacent the tops of the girders 2. In the present instance I have shown these doors as pivoted to brackets 22 secured to said girders. hen in closed position the doors 21 contact with the under edge of the sides 12 and with the flanges at the upper edge of the girders 2.

lVhile the dump doors 21 may be operated by any suitablemechanism, I have found that the utility of the car is greatly increased by employing the mechanism shown herein, which is located entirely beneath the floor level, thus leaving the space above the doors unobstructed, which is a great advantage when the car is adjusted for use as a side dump car with the floor sections 13 turned inwardly to form an A center. The operating mechanism shown comprises stationary supporting rails 23 constructed in the form of loops depending from and secured at their ends to the cross members 23. The inner portion of the suphinged at their inner edges porting rails 23 inclines upwardly and outwardly, and at the outer end a short horizontal rest 24 is provided. Operating shafts 25 rest upon the rails 23 and are adapted to move from end to end thereof. This more ment is accomplished in the present instance by means of chains 26 secured at their outer ends to the cross members'3 and at their inner ends to the-shafts 25. Rotation of the shafts 25 in a direction to wind the'chain thereon will cause said shaft-s tomove toward the sides of the car, thus raising the dump doors from the position shown at the right of Fig. 1 to that shov; at the left. Any uitable mechanism may be employed for imparting such rotation to the shafts 25. In the present instance I use levers 30 at the ends of the car, as shown in Fig. 4. These levers may be provided with reversible pawls co-acting with star wheels upon the shafts 95. These parts are not v hown in the drawing, but may be of any desired form, that illustrated in connection with shaft 31 of the mechanism for operating the hopper door being well adapted to the purpose. I

The door 6 of the central hopper is oper' ated by means of a chain 32 connected at one end to an eye bolt 33 secured to said door and at the other end to a rotatable shaft'Pil. The shaft. 31, as illust'ated in Fig. 4. is operated by means of a'levcr 35 carrying a reversible pawl 36 which cooperates with a star wheel 37 fixed to the end of said shaft 31. The shaft 31 is held against backward rotation while the door 6 is being closed by means of a double pawl 38 pivoted at 3%) to a plate depending from the end sill. The double pawl 88 also serves as an escapement which permits the door 6 to be opened step by step when the lever 39. forming part of said double pawl is oscillated.

From the foregoing it will be apparent that I have provided a center and side dump car from which the entire contents will be discharged, whether adjusted for center or side dump. Allparts of the car incline toward the discharge openings in each adjustment. Furthermore, the space above the central hopper is free from longitudinal supporting members, thus leaving this part of the car free for the discharge of its con-. tents. Furthermore, by the use of the type 'of operating mechanism shown for the side dump doors, the interior of the car is unobstructed when adjusted for side dumping, all of the operating mechanism being located beneath the doors.

I claim:
