Description

April l2, 1932. w. P. MURPHY RAILWAY CAR CONSTRUCTION Original Filed Jan. 14, 1929 Patented Apr. 12, 1932 UNITEDy STATES insane rma-:NrI ortica WALTER P. MURPHY, 0]."` CHICAGO, ILLINOIS, ASSIGNOR TO UNION METAL PRODUCTS COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAIVARE RAILWAY .CAR CONSTRUCTION Original application led January 14, 1929, Serial No. 332,326.y Divided and this application filed .Tune 22,
tion of a pair of swingable doors in a rail-V way freight car, which spreader is operated by any of the numerous door yraising mechanisms now being marketed. `A further object of the invention is to provide such a spreader or beam with spaced apart portions, each of which preferably engages one .of the swingabledoors preferably adjacent its vertical medial line, whereby the spreaderforms an equalizing lever. Any force appliedy by the operating mechanism` adjacent the middle of the spreader is substantially equally distributed to the two doors, and furthermore, the force transmitted to one of the doors by the spreader is substantially equally distributed to the oppositey vertical edges or' margins of the door.
A further object of the invention is to reduce the cost and weight of the spreader and car by forming it of a casting so that the metal can be evenly distributed commensurate with the stresses.
Another object of the invention i s to engage the spreader with the door adjacent a stiifening rib or ribs so that the stresses caused by the shifting of the door will not be taken by the body portion of the door.
In the drawings:
Figs. l and 2 show the preferred form ofV my device.
In a so-called hopper car the lower portion of the car on each side of the center sills or center ridge is formed into a hopper, each hopper beingprovided with a swingable door. simultaneous operation by a spreader operated by a mechanism connected to the middle vportion thereof and positioned between the center sills and under the ridge for protection from the lading and provided with ay shaft extending to opposite sides of the car` for operation by a wheel or wrench. There are numerous types of hopper dump cars 1n These doors are connected forr Serial No. 545,979.
service on the railways with the hopper so positioned as to discharge the load between the rails and some designed to discharge the load outside of the rails and there are also sot called general service cars of the gondola type having flat floors comprising a plurality of hinged doors, such doors being hinged to the center construction so as load outside of the rails.
dump cars used in the coke service having a licor sloping toward one side of the car with the sideV wallcomprising a plurality of swingable doors to discharge the coke all on one to discharge the There are also side of the car. My invention is adaptable tofany one of the above described cars, or in fact, to any car having two or more doors simultaneously closed by a single operative mechanism.
In the form of my invention illustrated,
each end of the spreader is formed of a U-shaped construction 48 which overlaps the reinforcing central rib 49 of the door and is preferably secured thereto by the bolt 50 or other similar means. The inner portion 51 and the side portion 52 of the U-shaped construction yof the spreader preferably fit the adjacent parts of the rib so as to provide a substantially rigid construction between the rib and the spreader.
The accompanying drawings illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that! vawith a reinforcing rib, and a spreader having spaced apart U-shaped portions, each straddling the reinforcing rib of one of said doors n and rigidly secured thereto.
2. In a railway car, a pair of hinged dumpu ing doors, each having a body ypart provided with a reinforcing rib formed with a straight central member with other members extending to the corners of the door, and a spreader having spaced apart U-shaped portions, each straddlng the said central member of the rib of one of said doors and rigidly secured thereto.
