To all whom it may concern:

Be it known that we, ALFRED G. NELSON and EDGAR Pl. REILLY, both citizens of the United States, residing, respectively, at Lakewood, Cuyahoga County, Ohio, and Youngstown, lvlahoning County, Ohio, have invented a new and useful Improvement in Cars, of which the following is a full, clear,

- and exact description.

The present invention relates broadly to cars of the type adapted for the conveyance of hot metal, slag, cinder, and the like.

Cars of this character are usually referred to as cinder cars, and will be so referred to herein, it being apparent that the word is an inclusive one.

It has heretofore been found that-the most successful container for most purposes for use in cinder cars is a vessel in the shape of a cone of substantially uniform section having a maximum diameter of about ten feet at the top, on account of railway clearances, and a depth of from seven to eight feet. These are usually made of cast iron 'or steel of uniform sec tion. Such containers have a much longer life, due to their ability to uniformly withstand contraction and expansion strains to which they are subjected.

Heretofore trucks have been built of sufficient strength to adequately take care not only of the transportation shocks to which they are subjected in cinder car work by the single pot or vessel which they carry, but to take care of a considerably greater load. Such trucks have, however, to our knowledge, never been. loaded up to capacity. This has perhaps been due to the fact that such cars have usually been built of steel castings, thereby making it extremely diflicult to handle more than one pot to a car. This has resulted in increased switching charges, which are made on the car basis, decreased locomotive efficiency high upkeep, and inefficient storage.

By the present invention these objections are obviated and there is provided a cinder car construction in which a plurality of pots maybe carried by a single car.

It has also been customary in this art to'provide the cinder cars with mechanism for tilting the pots to effect the desired emptying thereof. This mechanism has ordinarily been so constructed that a consid erable leverage has been exerted on the trunnions in a manner producing a binding action. This has been true very largely by reason of the fact that a considerable overhang has existedbetween the point of power application and the trunnion. With the construction provided herein, this overhang is reduced to a minimum and the efficiency of the operating mechanism is therefore materially increased.

In the accompanyingdrawings, there is shown for purposes of illustration only, one embodiment of the present invention, it being understood that the drawings do not define the limits of the invention, as changes may be made in the construction and operation therein disclosed without departing from'the spirit of the invention or scope of our broader claims.

In the drawings,

Figure 1 is a diagrammatic side elevation of a cinder car constructed in accordance with the present invention;

Figure 2 is a top plan view, partly broken away, of the construction illustrated in Figure 1;

Figure 3 is an end elevation of the construction illustrated in Figure 1:

Figure 4 is a top plan view, partly broken away,v illustrating the pot supporting frame:

Figure 5 is a detail sectional view, on an enlarged scale, of a portion of the actuating mechanism for tiltingthe pot frame;

Figure 6 is a sectional view, partly in elevation, on the line VI VI of Figure 5; and

Figure 7 is a detail view, partly in elevation and partly in section, illustrating a portion ofthe pot frame construction.

At the present time, switching charges for cinder cars are based on the car basis. For this reason it is desirable to increase the capacity of each of the carsto as large an extent as may expeditiously be done. Cinder cars as usually constructed have an over-all length of about twenty-three feet. By thepresent invention a cinder car having twice the capacity may be constructed with an over-all length of only 37 feet. This is of materialadvantage, as will be apparent to those skilled in the art, as the length of the cinder runners may be correspondingly decreased. At the same time,

the upkeep of the cinder cars is materially reduced, as the capacity for the same number of cars is substantially double.

In the illustrated embodiment of our invention, there is shown a cinder car comprising supporting trucks 2 of any desired construction, such as commonly used. These trucks may be connected by spaced, parallelly extending longitudinal sills 3 tying the trucks together and maintaining the same in predetermined spaced relationship. The sills 3 may be braced in any desired and convenient manner by providing transversely extending braces i at suitable intervals. The sills 3 and the braces a may be generally of I-beam shape, thereby making it possible to utilize rolled material for this purpose.

Each of the trucks may be provided with a standard 5, each having formed on its upper surface a track 6 and an adjacent rack 7, such as frequently provided in cinder car construction.

In the present invention, instead of providing heavy steel castings for the pot frame, we preferably construct this frame also of rolled shapes. In the form illustrated, the frame may be composed of side beams 8 having their ends 9 inwardly curved and terminating in spaced relationship. Extending between the spaced ends of each of the side beams are end trunnions 10 comprising a casting having divergent arms 11 adapted to cooperate with the inturned ends of the side beams and be secured to the webs thereof between the flanges. Each of these trunnions may have a circular bearing portion 12 adapted to have keyed thereto supporting wheels comprising flanged portions 13 for cooperation with the tracks 6, and gears 14s for cooperation with the racks 7. By reason of this construction, the ends of the frame may be caused to move in unison and the longitudinal axis of the frame main tained in alinement with the longitudinal axis of the car trucks. he arms 11 of the end trunnions may be braced by suitable webs 15 having curved inner surfaces 16 which preferably substantially correspond to the curvature of the cinder pots.

Atintermediate points, the side beams 8 are connected by transversely extending curved beams 1'7 secured to the side beams at their ends toprovide a plurality of pot receiving openings in the frame. It will be apparent that the beams 17 are preferably curved to substantially conform to the curvature of the pots. The beams 17 may be braced in any desired manner at their central portions by braces 18, as clearlyshown in Figures 4t and 7. After the beams and t-rnnnions of the pot frame have been secured. in position, we preferably cover the frame by securing thereto a topplate 19 having spaced openings 20 therein, and a lower plate having spaced openings 22 for ied therein. The openings 22 in the plates 21 are preferably of considerably less diameter than the openings 20 in the top plate, the difference in diameter being provided in accordance with the different diameters presented in difierent horizontal planes by the cinder pots 23. These cinder pots may then be lowered into position in the frame, wherein they will be held against movement by the top and bot tom plates. The pets 23 may be provided with supporting lugs 24 on their sides to cooperate with the upper surface of the pot fr me, and with locking lugs :25 to coopera e h the lower surface thereof.

From the foregoing it will apparent that we have provided a pot frame which may be largely constructed of rolled shapes, thereby enabling the same to be easily and inexpensively produced, while affording the necessary strength to meet the load requirements and withstand transportation shocks.

For moving the pot frame laterally and thereby causing the gears 1 1 to roll in the racks 7 and effect a tilting movement of the pot frame, there may be provided on one of the trucks a suitable actuating motor 26. .his motor may have a driving pinion 27 meshing with a gear 28 on the worm shaft 29 extending transversely of the truck frame and rotatably journaled in suitable bearings 80. The worm shaft 29 has secured to its outer end a spur gear 31 meshing with a sin'iilar gear 32 on a second worm shaft 33.

Due to this construction, it will be apparent that when the motor 26 is operated, the worm shafts 29 and will be rotated in unison in opposite directions. The worms on these respective shafts extend in opposite directions, and each of the shafts is provided with an interiorly threaded nut 34.

These nuts are formed with wings dapted to slide in slots 36 in the actuating ili le 37. This slide carries a pin 38 projecting therefrom and adapted to extend into the hollow bearing formed in the trunnion 10, as clearly illustrated in Figures 6 and 7. By this construction, rotation of the worm shafts will move the slide 37 in one direction or the other, this movement being transmitted through the pin 38 to one of the trnnnions 10. This will tend to move the entire pot frame laterally, and this movement, due to the gear tracks, will effect the desired tilting movement thereof.

By the provision of upper and lower worm shafts, arranged above and below the actuating pin 38, the overhang which exists between. the trunnion mounting and the point of power application is reduced considerably beyond that which can possibly be obtained where a single worm shaft is utilized and located at the end of the actuating pin, By reducing this overhang, a

more efficient;- operation is secured, as the power required is cut down in proportion to the decrease in the friction. This correspondingly increases the length of life of the structure and facilitates the dumping operation.

The advantages of the present invention arise from the provision of a cinder car having a plurality of cinder pots carried thereby. Further advantages of the present invention arise from the provision of a pot frame constructed largely of rolled shapes and from the construction and operation of the supporting and actuating means therefor.
