Description

Nov. 26, 1929. J. RUFFING, SR 1,737,060
END GATE OR EXTENSION FOR MINE CARS Filed Feb. 14, 1929 Invenior By @Mm A iiorney Patented Nov. 26, 1929 SKIES JOHN RUFFING, SR., OF NOKOMIS, ILLINOIS END GATE R EXTENSION FOR MINE CARS Application filed February 14, 1929. Serial No. 339,836.
The present invention relates to improve-- ments in mine cars and has for its prime object to provide a structure wherein an extension or gate may be provided on the end of the mine car, said gate being mounted so as to swing inwardly of the car when empty.
Another very important object of the invention resides in the provision of an arrangement of strap plate hinges so as to afford a strong mounting for the gate or extension.
A still further important object of the invention resides in the provision of chain braces for the gate or extension.
A still further very important object of the invention resides in the provision of an improvement of this nature which is exceedingly simple in its construction, inexpensive to manufacture and install, strong and durable, and thoroughly etiicient and reliable in use.
/Vith the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.
Figure 1 is a transverse vertical section through a mine car showing my improved structure, and
Figure 2 is a detail section taken substantially on the line 2-2 of Figure 1.
Refor ng to the drawing in detail it will he that the numeral 5 denotes a mine car hating ends one of which is denoted by the tum-oral 6. Strap hinge plates are fastoned to the inner surface of the end wall 6 so that the eyes 8 thereof are disposed below the up per edge thereof. The numeral 9 denotes a rectangular gate, door or extension --ich has fastened thereto strap plate hinges stoned that the eyes 11 thereof are dis- .r. o l a distance outwardly from one longitudinal edge.
The pins 12 pivotally connect the eyes 8 and 11 so that the extension 9 may be disposed in vertical coplanar relationship above and with the end wall 6 or may swing down inside the car. lVhen the extension 5 is disposed as is shown in Figure 2 it will be seen that the hinge mounting affords a strong support therefor. To further strengthen this support a chain 14 is fastened to the extensions 9 and to the bottom of the car as is indicated at 15.
It will be seen that when the car is dumped of its load of coal these extensions may swing back into the car out of the way. i
It is thought that the construction, utility and advantages of the invention will now be quite apparent to those skilled in the art without a more detailed description thereof.
The present embodiment has been disclosed in considerable detail for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.
It is apparent that changes in the details of construction may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention, what I claim as new is:
In a mine car including an end wall, a pair of flat metallic straps fixed vertically to the inner surface of the wall adjacent its 0pposite ends and terminating at their upper ends below the upper side of the wall, in wardly turned hinge eyes on the upper end of the straps, a second pair of flat metallic straps extending at their lower ends into the car, inwardly turned hinge eyes on one end of the second named straps in horizontal alignment with the eyes on the first named straps, pivot pins extending through the aligned eyes of the first and second named straps for pivotally connecting said straps together, the second named straps adapted to be swung in a vertical plane into engagement With the inner surface of the end Wall, a rectangular extension member mounted on the upper portion of the second named straps adjacent the upper end of the end Wall and in the vertical plane thereof and a brace chain anchored at one endeto the upper portion of the rectangular extension and at its opposite end to the floor of the car at a point spaced from the end wall.
In testimony whereof I aifix my signature.
JOHN RUFFING, SR.
