GEORGE E. THACKRAY, OF WESTMONT BOROUGH, PENNSYLVANIA.

Specification of Letters Patent.

Patented Dec. 2'7, 1921..

Application filed August 15, 1921. Serial No. 492,337.

To all whom it may concern Be it known that I, Gnoncn E. THACKRAY, a citizen of the United States, and a resident of the borough of Westmont, county of C'ambria, and State of Pennsylvania, have invented certain new and useful Improvements in Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My inventlon relates to a car adapted for use in and about coal and other mineral mines or in and around manufacturing plants or for use on what are known as industrial railways.

The car body is preferably formed of a plate or sheet of metal pressed into form, the bottom and sides being integral and the ends formed of flanged sheets or plates secured to the other portions by bolting or rivetin to form an open top box-like structure.

T e main portion of the bottom of my car is flat in order to obtain the largest capacity in a small compass. On account of the necessary comparatively thin metal of'which the car body is composed, the bottom portion is not strong enough to resist the bufling stresses, particularly when such cars are handled in a long train, so that I strengthen and stiffen the construction by pressing portions of the bottom downwardly in channel form and other portions upwardly in a similar way forming shallow troughs of channel form, and then introduce between these portions a longitudinally extending center sill made of heavy and substantial timber, preferably oak or other good quality of wood.

The center sill is preferably secured to the car bottom as thus arranged by means of through bolts extending through the sill and portions of the car bottom, and I may also provide reinforcing plates as may be necessary to further strengthen-and stiffen the construction where needed. 1

In addition to the wooden center sill thus introduced into the metal car body I may also use a continuous draw bar attached thereto and extending throughout the length 7 of the car, the ends of same being bent upwardly and spaced apart from the bumpers mounted on the ends of the wooden center sill, which ends extend outwardly from the car body the ends of the continuous draw bar and .umpers being provided with registering holes to receive the coupling pin, which secures the cars together in the train. -.I may, however, omit the continuous draw bar and depend principally upon the action of the wooden center sill and'the car body to withstand the bufling and pulling stresses, and in such case I prefer to make the buffer with integral projections above same adapted to receive the coupling pin as described and illustrated.

On account of the necessarily small thickness of the metal is not best adapted to withstand the excessive bufling stresses or pulling stresses, but is primarily designed as a container for the lading. The introduction therein ofthe heavy wooden center sill makes the structure very plate or sheet, the car body well adapted to withstand the bufling stresses and pulling stresses on account of the large,

area of the wooden sill, which reduces the unit stresses therein, beside which wood has a certain amount of elasticity, but the modulus of elasticity is much'lower than steel and it also has certain shock absorbing qualities and the reaction after a shock is not so energetic as that of steel, so that the wooden sill is very effective and useful in such cases.

Having thus given a general description of my invention, I will now, in order to make the matter more clear, refer to the annexed sheet of drawings, which. forms part of this specification, and in which like characters refer to like parts.

Figure 1 is a top plan view of my improved car; Fig. 2 is a side elevation of the car with the left hand portion shown in vertical sectional elevation on the longitudinal transverse sectional elevation taken on the line III-III of Fig. 2; Fig. 4 is a top plan view illustrating a modified form of buffer block, and Fig. 5 is a longitudinal section taken on the line V-V of Fig. 4.

Referring now to the characters of reference on the. drawings: 1 is a car body in general, which is formed of pressed plate or sheet metal; 2 are the sides thereof and 3 is the bottom; the bottom portions 4 are pressed upwardly therefrom and are integral therewith, this being'of U-shape or channel form, and similar downwardly extending portions 5 are also provided. Between these portions 4 and 5 and at the longitudinal center of the car, I introduce a heavy, strong wooden center sill 6, secured to the adjacent portions bythrough bolts as illustrated, the ends of said center sill extending outwardly from the car body as illustrated in order to receive the buffers 17 mounted on the ends thereof. A reinforcing plate 7 is secured to the central side portions, of the car bottom adjacent to the bearings for the axles, and similar reinforcements 8 may be secured to the bottom of the car, and through these, the car bottom and the flanges of the car journals-the bolts 9 pass and firmly secure the axle bearings to the car bottom. These reinforcing plates add strength and stiffness to the car and maintain the axles in proper parallelism thereon. Above .the center sill and secured to the adjacent portions I may provide a continuous draw bar 10, the intermediate ortions of which are secured by means of t e bolts 11, and this draw bar has bent-up end portions 12 secured tothe adjacent parts by means of the bolts 13. The car ends are 14 as illustrated, riveted or bolted to the ends of the car body by means of their flanges and this adds strength and stiflness to the construction. The type of car with fixed ends of this kind is best adapted forunloading in a rotary car dump or by shoveling as heretofore customary. On the outer ends of the center sill l[ mount bufler blocks 17 which are secured at their central portions by means of the bolts 13 and are further provided with laterally extending cars 15,

which are secured to the other partsb means of the bolts 16. The buffer blocks 1 are each provided with a striking or bufling face 18, a bottom-flange 19 and a top flange 20, adapted to rest against the center sill 6. The ends of the draw bars 10 are Provided with holes 21 which are adapted to register with the corresponding holes 22 through the buffer blocks and center sill to receive the coupling pin 23, and the buffer block is provided with an upwardly extending projection 24:, adapted to serve as a spacer between the end 12 of the draw'bar and the upper flange of the bufler block, thereby providing space for the coupling link as illustrated.

Referring now particularly to Figs. 4 and 5 This illustrates a modified form of buffer block 25 in which the coupling portion is integral therewith, this being preferably formed of a steel casing; this buffing block has a bufling face 26, a bottom flange 27, a top flange 28, a clevis member 29 spaced apart from the other parts in order to provide space between the same for the reception of the coupling link; 30 is a hole through the clevis member; 31 is. a hole through the flange of the bufling block, which hole also extends through the wooden center sill 6. The bolt 33 is adapted to pass through theinner ends 34 of the bufler and through the continuous draw bar 10 and other adjacent parts, including the wooden center sill 6 and through the laterally ex tending tie bar 35, which is below the car floor and serves to strengthen and stiffen this portion. 36 are bolts which pass through the buffer member and the adjacent portions in order to secure the parts together firmly, and 32 is the hole in the end of the draw bar.

Although I have described and illustrated my invention in considerable detail, ll do not wish to be limited to the exact and specific details thereof as shown and described, but may use such modifications in, substitutions for, or equivalents thereof, as areembraced within the scope of my inventlon or as pointed out in the claims.

Having thus described my inventlon, what I claim and desire to secure by Letters Patent is: I

1. A metal car body, portions of the bottom of which are pressed downwardly and others upwardly' to form shallow troughs and a wooden center sill inserted therebetween and secured thereto.

2. A metal plate car body, the central longitudinally extending portion of whlch has portions pressed upwardly and other portions pressed downwardly, forming open troughs integral with the bottom, and a substantial wooden center sill mounted in sa1d troughs and secured to the car body.
