MINE-CAR-DUMPING APPARATUS.
Application filed August '7, 1916. Serial No. 113,425.
To all whom it may concern: I
Be it known that I, "WILLIAM A. WIL- LIAMS, a citizen of the United States of America, and resident of Barton, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Mine-Car-Dumping Apparatus, of which the following is a specification.
This invention relates broadly to minecar-dumping apparatus, and more particularly to mechanism for elevating and lowering the dump-platform upon which the loadedcars stand while being emptied of their contents.
The primary object of the invention is to provide a simple, efficient and conveniently operated mechanism for actuating the usual dump platform at a tipple.
A further object is to provide a device of the character mentioned having such a construction that the dump-platform may be elevated to the limit of its upward movement and permitted to remain indefinitely in such position without disarrangement of the actuating mechanism.
With these and other objects in view, the invention resides in the features of construction, arrangement of parts and combinations of elements which will hereinafter be fully described, reference being had to the accompanying drawings, in which Figure 1 is a top plan view, partially in broken section, illustrating the invention; and
Fig. 2 is a partial vertical sectional view of the same.
Referring to said drawings, 1 indicates the tail-piece of a dump-platform of an ordinary type, a counterpoise weight, as 2, being commonly carried by said tail-piece. Depending from said tail-piece and having one end connected thereto is an arcuately curved bar 3, commonly termed a brakesword, to which is applied the power whereby the tail-piece 1 is' elevated for inclining the dumping platform to cardumping position. To provide for the elevation of said brake-sword, the latter is attached to that portion of a power-driven endless chain 4 located between two suitably positioned pulleys or idlers 5 and 6 which are disposed in a vertical plane. While the attaching means may be of any appropriate form, I prefer to employ a rearwardly directed arm 7 the same being rigidly carried by the lower end of the brake-sword, and having its outer end terminated by a hook 8 which is directed through, or connects, two adjacent links of the chain.
. The chain 4 operates over a sprocket wheel 9 loosely carried by a shaft 10 which has its ends journaled in suitable upright supports 11. A friction clutch 12 rotatable with said shaft is shiftable, as by means of a' lever 13, into and-out of operative relation to a disk 14 which is disposed in fixed relation to said sprocket wheel. Motion is communicated to the shaft 10 through a gear wheel 15 carried thereby, said Wheel being in mesh with a pinion 16 mounted on a countershaft 17 which also carries a worm-gear 18 in mesh with a worm 19 carried by a suitable drive-shaft, as the shaft 20 of an electric motor 21.
In practice, the clutch 12 is shifted into operative relation to the disk 14, whereupon the sprocket wheel 9 is actuated to rotate, and, through the chain 4, the brake-sword 3 is elevated for inclining the dump-platform to car-dumping position.
The uppermost idler is so located that the limit of. elevation of the platform is I reached without the hook '8 coming into enthe mechanism is prevented. Consequently,
the platform may remain for an indefinite period in its elevated position without injury to the actuating mechanism. When the clutch is shifted to inoperative position, the platform immediately drops to its normal position, the weight of its parts being so balanced that a horizontal position is normally retained.
What is claimed is The combination with a dump platform havingmeans whereby it is normally held in horizontal position, of a rigidly mounted brake-sword depending therefrom, an endless sprocket chain, suitably located pulleys over which said chain operates,a c011- stantly driven shaft, a drive-sprocket loosely mounted on said shaft, a disk disposed in fixed relation to said sprocket, a shiftable friction clutch mounted on said shaft and clutch into and out of operative relation to said disk whereby rotation is communiture in presence of two subscribing witcated ta) said: sprocket, anddmeans connectnesses. ing sai rat e-sword to sai chain whereby when the latter is driven forward the for- WILLIAM WILLIAMS mer is elevated for moving said platform Witnesses: to inclined position.
