THOMAS R. MCKNIGHT, OF AURORA, ILLINOIS, ASSIGNOR TO WESTERN WHEELED SCRAPER COMPANY, OF AURORA, ILLINOIS, A CORPORATION OF ILLINOIS.

DUMP-CAR.

T0 all whom t may concern.'

Be it known that I, THOMAS R. MC- KNIGHT, a citizen lof the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specilication, reference being had to the accompanylng draw- 1n s. l(li/Iy invention relates to dump-cars in which the car bed is arranged to be dumped :1t-either side by the use of compressed air supplied through train-pipes and controlled from the cab of the locomotive, and it has for its object to provide means by which any desired car 0r cars'which it is not desired to dump may be conveniently cut out so that the rest of the cars in the train may be dumped independently of the car or cars so cut out.

A further Object is to provide means by which-the cutting out of any car or cars may be accomplished from either side of the train and from either end Aof each car.

I accomplish these objects as illustrated in the drawings and as hereinafter described.

That which I believe to be new is set forth in the claims.r l

In theaccompanying drawings, Figure 1 is a side elevation of a dump-car illustrating my improvements; Fig. 2 is a plan view illustrating such improvements; and Fig. 3 is a detail, being a partial side elevation of a part of the cut-out mechanism.

Referring to the drawings, 4 indicates the under body of the car, which is equipped with cylinders 5-6 at opposite sides 'and near its opposite ends, byythe admission ofY air to which the car bedvis dumped at one side or the other of theftrack. The mechanism by which the admission of air to the cylinders 5 6 effects the dumping of the car bed forms no part of my present invention and is therefore not illustrated in detail. Reference, however, may be made to LettersPatent No. 1,063,276, granted June 3, 1913, as illustrating one form 40f mechanism which may be advantageously employed for that purpose.

7 8 indicate train-pipes connected, re-

spectively, with the cylinders 5-6 by branch pipes 9-10, as shown in Fig. 2. Said branch pipes are provided with valves 11-12 which, when opened, operatively connect the dumping mechanism with the respective Specication of Letters Patent.

train-pipes 7 8, and when closed, cut off such lmechanism from the train-pipes. The stems of the valves 11-12 are provided with levers 13-14 by which they may be conveniently operated.

15 indicates a lever, one end of which is pivoted at 16 on the under body of the car near one end thereof. The freeend of said llever is connected by a connecting-rod 17 with a rod 18 which is connected to the lever 13 and also to one arm of a bell-crank lever 19 pivoted at 20, as shown in Fig. 2.

21 indicates an operating-rod connected to the other arm of the bell-crank lever 19 and extending at one side of the car so that it may be conveniently grasped by the operator when it is desired to rockthe lever 19 to open or close the valves 11--12. It will be apparent that in the construction shown, by pulling out the operating-rod 21 the bellcrank lever 19 will be rocked so as to swing the valve-lever 13 to the right. Movement of the operating-rod 21 in the opposite direction will turn the valve to the left.

22 indicates a lever fulcrumed intermediately at 23 on the under body of the car, near its opposite end, and connected at one end by a connecting-rod 24 with the lever 15 at the opposite end'of the car. At the, opposite side of its fulcrum the lever 22 is connected by a connecting-rod 24a with a rod 25 which connects the valve-lever 14 with a bell-crank lever 26 pivoted at 27 upon the under body of the car. the lever 26 is provided with an operatingrod l28 which projects at the opposite side of the car fromvthe operating-rod 20, as shown in Fig.

From the foregoing description it' will be seen that when the operating-rod 21-is operated to turn'the valve 11 totheright, t-he i lever 15 will also beswung to the right, and through the -connectingfrodA 24' the` lever 22 will be actuated to-pullfftheconnecting-rod 25 to the left.v .VIhe'valvel 12, being at the opposite side ofthe car, will accordingly be turned in a direction corresponding to that in which the valve 11l is turned. Similarly, movement kof the operating-rod 21 in the opposite direction operates both valves reversely. In the same way, both valves may be operated by operatingfthe operating-rod 28. Thus, the operator may open or close both valves 11 and 12 from either side of the car or from either end thereof, and so cut The other arm of olf both cylinders 5-6 simultaneously JfromA the train-pipes, or connect them therewith, as may be desired. This, of course, does not interfere in any Way with the flow of air through the train-pipes.

That which I claim as my invention, and desire to secure by Letters Patent, is,-

1..The combination with a dump-car having dumping cylinders for dumping the car at one side or the other respectively and means connected with said cylinders for supplying compressed air thereto, of valves for controlling the admission of compressed air to said cylinders, and means whereby said valves may be simultaneously opened or closed.

2. The combination with a dump-car hav'- ing dumping cylinders for dumping the car at one side or the other respectively and means connected with said cylinders for supplying compressed air thereto, of valves for controlling the admission of compressed air to said cylinders, and devices at opposite sides of the car adapted to be actuated to simultaneously open or close both valves.

3. The combination with a dump-car having dumping cylinders for dumping the car at one side or the-other respectively and means connected with said cylinders for supplying compressed air thereto, of valves for controlling the admission of compressed air to said cylinders, and devices at opposite ends of the car adapted to be actuated to simultaneously open or close both valves.

4. The combination with a'dump-car having dumping cylinders for dumping the car at one side or the other respectively and means connected with said cylinders for supplying compressed air thereto, of valves for controlling to said cylinders, levers adjacent to the opthe admission of compressed airl posite ends of the car, means connected with said levers respectively for opening or closing said valves when saidlevers are actuated, and means for actuating said levers f simultaneously.

' 5. The combination with a dump-car having dumping cylinders for dumping the car at one side or the other respectively and means connected with said cylinders for supplying compressed air thereto, of valves Jfor controlling the admission of compressed air to said cylinders, levers adjacent to the opposite ends of the car, means connected with said levers respectively for opening or closing said valves when said levers are actuated, and bell-crank levers connected With said first-mentioned levers for actuating` the same. i (5. The combination with a dump-car having dumping cylinders for dumping the bed in one direction or the other, train-pipes connected respectively with said cylinders, valves between said train-pipes and said cylinders, and means for simultaneously opening or closing said valves.

7. The combination with a dump-car having dumping cylinders for dumping the bed in one direction or the other, train-pipes connected respectively with said cylinders, valves between said train-pipes and said cylinders, levers at opposite ends of the car, means connecting said levers with said valves respectively, and means connecting said levers together whereby said valves are operated in unison by the actuation of said levers.
