RAILWAY CAR.

Specification of Letters Patent.

Patented Aug, 1922.

Application filed May 3, 1920. Seriall No. 378,384.

To all whomz't may wacom: n

Be it known that l, JOHN O. NEIKIRK, a citizen of the United States, residing at Lombard, in the county of Du lage and State of Illinois, have invented certain new and useful inproycments in Railway Cars, of which the following is a specilication.

This invention relates to railway cars, and primarily to hopper cars of the type especially adapted for the distribution of ballast, although these cars may also be used for other purposes, such as the carrying of commodities.

One object of my invention is to simplify and improve the car construction by reducing the number of sills employed, at the same time making adequate provision for the distribution of the load and of the pulling and buliing strains to the underframe of the car.

Another obj ect is to provide a car of this type in which the hopper is supported in a simple, novel and durable manner.

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheets of drawings, in which- Figure 1 is a fragmentary side elevation of a railway car embodying my invention;

Figure 2 is a transverse sectional view Oic the same car; and,

Figure 3 is a vertical longitudinal sectional view O the same car.

The various novel features of my invention will be apparent Jfrom the following description and drawings and will be particularly pointed out in the appended claims.

Referring to the figures oi' the drawings, it will be noted that I have disclosed my invention in connection with a hopper type of car, in which the hopper 10 has sides 11 which converge downwardly and inwardly toward the longitudinal center of the car.y

The lower portion of one of the hopper sides intermediate the truck wheels 12 is in the form of a door 13 pivoted at 14,- and controlled by any suitable door operating mechanism 15. The upper portions 11ZL of the hopper side walls 11 are arranged vertically. The hopper end walls include an upper vertical portion 16 and a downwardly and inwardly inclined sloping portion 17.

This hopper, as above described, rests upon an underfraine structure, which is composed of two longitudinally extending sills 18 and cross members 19, the cross meinbers at the trucks between the sills constituting the holsters, as will be readily understood, so that the bolsters and the longitudinal sills 18 form. a framework upon which the hopper rests, the lower portion of the hopper extending downwardly between the longitudinal sills. These longitudinal sills are or" size and strength suflicient to carry the entire vertical load of the car, and do, as a matter oi' fact, carry the greater part of such load; that is, they carry all the vertical load except that which is transmitted downwardly direct to the holsters. rhese longitudinal sills also take the entire pulling and buiiing strains. 1t will be noted that these sills are theonly longitudinal sills and that the same are located intermediate the positions normally occupied by the usual side sills and usual center sills. These sills 18 are spaced apart a suilicient amount to receive a large portion of the hopper and permit the hopper to occupy a relatively low position, and in this way be of large capacity and at the same time be within the standard height limits for the hopper type oi car. As shown, these longitudinally extending sills 18 are vertically arranged, the webs being in parallel planes entirely outside of the wheels 12. These sills 18 include oppositely arranged and oppositely extending angle members secured to the upper and lower edges of the webs of the sill structure.

Secured to the outer sides of the sills 18 are a plurality of bracket or frame members 2O which diverge outwardly and upwardly from the sills and have vertically arranged portions 21 which conform to and are secured to the webs of the longitudinally extending sills 18 and also have upwardly and outwardly inclined portions 22 which conform to and are secured to the downwardly and inwardly converging hopper sides 11. These brackets or frame members 2O extend upwardly and outwardly to the vertically arranged portions 11a of the hopper and Jform, with the longitudinally extending sills 18, a basketlike structure Jfor receiving the hopper 10, thereby providing a strong, dui'- able, compact and rigid construction in which the hopper is iirmly supported and in which but two longitudinally extending sills take the greater part of the vertical load of the hopper and its contents, and also take the entire pulling and bufiing strains. This arrangement permits of the use of a hopper whichl is ofy full capacity and in which the "center of gravity is maintained at a low point in a manner to meet all of the requirements. By referring particularly to Figure l of the drawings, it will be noted that the longitudinally extending sills increase in depth toward the transverse center of the car to increase the strength thereof at the middle section off the car where the bending strains are greatest.

It is my intention to cover all modifications o'f the invention falling within the spirit and scope of the following claims..

I claim:

l. In a railway car, a sill structure in which there are only two longitudinally eX- tending sills, said sills being located outside y ofthe truck wheels and betweenr the normal positions oit' the regularV center sills and side sills, said two longitudinally extending sills takingtheyertical loadand the pulling and buffinfr strains.

2. n a railway car, a sill structure,the sole longitudinally extending members of which comprise a pair of spaced sills located outside of the truck wheels, and a hopper supported. upon said sills, and having sides sloping inwardly continuously 'from points outside and above the sills and meeting intermediate the sills.

Signed at Chicago, illinois, this 17th day of April, 1920.

JOHN o. Nannies.
