END BRACiNe Fos' Box-CARS'.

SPECIFICATION forming part of Letters Patent No. 678,258, dated my" e, ieoi.

Application led April 18, 1901.

To all whom it may concern; c

Be it known thatI, GEORGE I. KING, acitizen of the United States, residing at the city of Detroit, in the county of Wayne, State of Michigan, have invented a certain new and useful Improvement in End Bracings for Box- Cars, of which the following is a full, clear,

and exact description, such as will enable others skilled in the art to which it apperio tains to make and use the same, reference be.

ing had to the accompanying drawings, forming part of this specification, in which-- Figure lis an elevational view of the fram'- ing of a box-car, showing my improved end I5 bracing. Fig. 2 is a vertical sectional view showing my'vimproved bracing with the end walls and the roof in position. Fig. 3 is a sectional View on line 3 3, Fig. l; and Fig. 4

is a detail viewof one of the castings used 2c in connection with the vertical post.

This invention relates to a new and useful improvement in car construction, being designed particularly for strengthening the end framing of box-cars.` V

The object of my present invention is to make the end framing of box-cars sufficiently strong to prevent bulging in the transportation of loose loads, such as wheat, dac. Boxcars as commonly constructed with wooden 3o sills and end posts are liable when the'car is being switched and subjected to shocks Yand jars to bulge the end walls,the connections between the wooden posts and end sills not being strong enough to withstand the severe strains to which they are subjected v.under the impaction of loose loads. Sometimes the end walls of box-cars are forced out under the above conditions, so that the load contained in the car finds an exit through which it may 4o escape. Especially is this true when the car is loaded with wheat or other granular material. y

The purpose of my present invention is to make the endY framing of the car sufficiently strong to withstand such pressures which are usually suddenly applied, and to accomplish this in a simple and economical way I preferably employ metallic end sills and use metallic end posts,'which are riveted to the end 5o sill, the upper ends of the end posts having castings riveted thereto, which castings are Serial No. 56,426; (No model.)

strongly bolted or otherwise secured to the end plate.Y These end posts may be in the forin of channels `Ishaped in cross-section or other suitable'cross-sections, and in order to provide nailing-strips for the end walls of the car I preferably use furring-strips which are seated within the channels or bolted to the end posts.

In the drawings, A indicates the end sill, which is shown in the drawings as being made of a casting; but it is obvious that a structural metallic end sill may be used, or, for that matter, a wooden end sill can be employed. This end sill carries pockets a at its ends, in which are seated the corner-posts B and the end diagonals` C. These cornerposts and diagonals are preferably of wood, the end walls of the car being nailed thereto.

E indicates the metallic end posts, shown in the drawings as being I-shaped in section. These end posts are riveted to the metallic end sill by the use of connection-plates, as shown. f l

F indicates a casting which is formed to vprovide a pocket in which the upper end of the diagonal C is seated. This casting has an upwardly-extending flange, which is bolted to the 'end plate by the use of horizontallydisposed bolts. casting to the under face of the end plate and hold it in position thereon. The casting has a depending web or ange f, to which is riveted the upper end of the metallic end post.

G indicates a wooden furring-strip, which is seated in oneof the channels of the end post, being held therein by the employment of suitable bolts g. The bottom nailing-strips H for the floor may be bolted directly to the npper face of the end sill.

I am aware that box-cars have been constructed wholly of metal and wholly of wood. In some instances metallic members have been employed in the side framing, the remaining members of said framing being made up of wood. I am not aware, however, 'of the use of metallic end posts arranged and combined with the metallic end sill and wooden end plate in the manner shown in the drawings and hereinabove described.

I am aware that minor changes in the arrangement, construction, and combination of Vertical bolts secure the- IOO 2. The combination with metallic end posts, of castings riveted to the upper end thereof, said castings affording seats for the wooden diagonals in the end framing; substantially as described.

3. The combination with a metallic end post, of a casting having a depending web which is riveted to said end post, said casting having a vertical iiange, and a horizon; tal flange for receiving the end plate, and bolts passing through said flanges for securing the casting to the end plate; substantially as described.

4. The combination with a metallic end sill, of metallic end posts riveted thereto, castings riveted to the upper ends of said end posts for aiording seats for the diagonals in the end framing, an end plate to which said castings are secured, and Wooden furringstrips secured in the channels of the metallic end posts; substantially as described.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 13th day of April, 1901.

GEORGE I. KING.
