HARRY S. HART, OF CHICAGO, ILLINOIS.
DUMP-CAR CONSTRUCTION.
Specification of Letters Patent.
Application filed May 24, 1918. Serial No. 286,275.
To all whom it may concern:
Be it known that I, HARRY S. HART, 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-Car Construction. of which the following is a specification.
This invention relates to freight cars of the type commonly known as hopper cars which are used very largely for the trans portation of coal or like dnnlpable material, and has among its objects the improvement of this type of car so as to greatly increase the load carrying capacity of the car with out changing its overall dimensions and to provide such a car from which the load may be more quickly discharged with a minimum amount of labor. the car being practically self clearin lVith these and other objects, which will hereinafter be pointed out, the invention consists in the combinations and details described in the following specitt cations and claims.
The invention is illustrated on the accompanying sheets of drawings, in which Figure l is a fragmentary side elevation of a dump car constructed in accordance with my invention;
Fig. a longitudinal sectional view of the same;
Fig. 3 is a transverse sectional view of the dump car taken intermediate the trucks;
Fig. 4 is a transverse sectional view of the dump car taken over the trucks; and
Fig. 5 is fragmentary plan view of the dump car.
Prior to my invention it has been customary to build hopper cars for the transportation of coal and the like commodities having inclined end portions over the trucks discharging the load through the center of the car by means of cross ho pers or longitudi nal hoppers provided with suitable doors. These prior constructions are well known and require no particular description for an understanding thereof. Owing to the location of the inclined end portions over the trucks that portion of the cars at the ends is largely useless for load carrying so that any attempt to increase the capacity of these cars has necessarily been by lengthening the car or by increasing its height, while the discharge of the load through the cross hoppers is dillicult even where special unloading stations are provided owing to the necessarily restricted door opening provided in the .cross hoppers. While longitudinal hoppers have also been provided in cars of this type for discharging the load at the side so as to make the unloading easier, attempts to apply this principle to the car throughout its length have resulted.
in a greatly decreased load carrying capacity. By my present invention I entirely overcome the difliculties hitherto experienced in this type of car, making it possible to carry in a car of the same length an increased load of approximately 20%, at the same time making it possible to discharge the load at a greatly reduced expenditure of time and labor.
The body 10 of this dump car, which is carried upon trucks including Wheels 11 at each. end of the car, comprises sides 12, ends 13 and a floor 14.
The floor 14 consists of downwardly and outwardly sloping portions 18 shown over the trucks extending from a point adjacent the center sill toward the sides of the car. Between the trucks the floor consists of downwardly and outwardly extending sections 21 secured along their inner edges to the center sill 20, preferably at or near the lower edge thereof, the floor portions 21 being at a lower level than the floor ortions 18. In. order that the car may be so f clearing in unloading, I have shown in the present embodiment of my invention the floor sections 18 over the trucks extending upwardly to a point over the center sill so as to form an A-shaped apex 15 as a continu ation of the floor sections. Between the trucks I have shown an A-shaped portion 16 mounted over the center sill so as to form shedding surfaces cooperating with the floor sections 21. It will be understood, however, that these A-shaped portions may be unnecessary in the event that a narrow center sill is used. The upper and lower floor sections at the ends and intermediate portion of the car respectively may be connected by a floor member 17 sloping downwardly toward the longitudinal center of the car. Suitable means may be provided for closing the space between the outer edges of the sloping floor sections and the sides of the car, through which space the load is dumped. In the present embodiment of my invention I have shown side dump doors 19, which are pivotally connected at the lower edges of thmsides 12, extending downwardly and Patented J uly 30, 1918.
inwardly with respect to the center of the car to meet the outer edges of the A-shaped portions 18 which are over the trucks. Simier doors 22 are pivotally connected to the lower ed es of the sides 12 between the trucks, tiese doors 22 being of greater length that the doors 19, so as to meet the outer edges of the sloping members 21. By thus providing a car having load carrying capacity throu hont its length with a stationa floor o the construction above doscribe d, I am enabled to provide a hopper ear of maximum load carrying capacity for any given len 11 and width, at the same time making t e ear self-clearing-owing to the arrangement of the inclined surfaces in the ear with relation to the dumping doors. The side dump doors .9 and 22 may be provided with any suitable operating mechanism. In this car I prefer to have the draft and center sills in alinement with each other.
By means of the construction above described the efl'eetive depth of the car is greatly increased not only over the trucks hut intermediate the same, the effective capacity of the car being greatly increased without increasing the overall height, length or width of the ear. The side dump doors and the floor of the car are so arranged and cooperate with each other in a novel manner to meet successfnlly all require ments.
It is my intention to cover all modifications of my invention falling Within the spirit and scope of the following claims.
I claim:
1. A car having side and end portions, a center sill, a stationary floor extending from end to end of the car and composed of fixed portions sloping downwardly and outwardly from the center sill toward the sides of the our, the floor portions over the trucks being at a higher level than the [ioor portions between the trucks, the ear sides comprisin upper stationary portions, and doors exten ing between the statloner portion of the sides and the outer edges 0 the floor. 2. A car having side and end portions and a center sill, a stationary floor extending; from end to end of the ear, said lloor being composed of fixed portions sloping down wurdly and outwardly from center sill toward the sides of the car. the floor portion between the trucks being at a lower levol than the floor portions over the trucks, and comprising fixed sloping portions attached. at their inner edges at or near the mint/w sill. 3. A car of the class described having sides, ends, and a. stationary floor extending from end to end of the our, the floor co1nprising end portions and intermediate portions, the intermediate portions extending. between the trucks only and bring at a lower level than the end portions. the end p0rtions and intermediate portions lining composed of fixed sections sloping down-.vardly and outwardly toward the siclrs of the car: -l' A car oi the class described. having n. centers-ill, a stationary floor i-xti-nrgling from end to end of the car, said floor being composrd of members sloping downward y and outwardly from the center sill toward the sides of the car. the portion of the floor between the trucks being at a lower level than the portion over the trucks, and doWnwardly sloping members connecting the fl or portions over the trucks with the floor portions between llllt trucks.
Signed at Chicago, Illinois. this 15th day of May, 1918.
