CLOADING-MACHINE FOR MINE-CARS.
sPIiCIFIcATIoN forming part of Letters Patent No. 761,695, dated June 7, 1904,
Application filed September 12, 1902. Serial No. 123,056. (No model.)
To in whom it may concern Pennsylvania, have invented certain new and useful Improvements in Loading-lilachines for Mine-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- I My invention relates to the mining of coal and other minerals, and particularly to that part of the mining operation which has to do with the loading of the material.
It consists in certain new and useful improvementsin apparatus for loading the material upon the usual mine-car after it has been blasted down in the customary way.
' In the accompanying drawings, Figure 1 represents a perspective view of one form of apparatus embodying my invention.- Fig. 2 represents a side elevation thereof. Fig. 3 representsa plan view thereof; Fig. 4: repre sents a front elevation thereof. Figs. 5, 6, and.7 represent, in plan, side elevation, and
end elevation, the pusher constituting one of the'features of the invention; and Figs. 8, 9, 10, and 11 represent, respectively, a plan View, side elevation, and end elevation of the scoop or shovel constituting another element of the apparatus.
Similar numerals of reference indicate similar parts throughout the several views.
Referring to the drawings, 1 indicates a truck-platform provided with traction-wheels 2 and turn-table 31, upon which the operating mechanism of the apparatus is mounted. Upon the turn-table 31 are mounted the uprights or columns 4, which through the intermediacy of suitable braces 6, of angle-iron, support the projecting channel-beams 7, which carry at their outer ends a pulley 8 upon the shaft 9. At the inner ends of the beams 7 is mounted a second pulley 10 between theuprights 4, the beams 7 being connected at said inner ends by a top beam, as shown, so as to impart additional stability to the general structure. Over the pulleys 8 and 10 runs a rope 11, from whose lower end depends a scoop or shovel, hereinafter more particularly described. The
other end of the rope is wound upon a hoisting-drum 13, operated through suitable intermediate transmitting mechanism 14: by the motor 15. By other suitable mechanism "16 and rack 26 the pusher is operated back and forth.
As more particularly shown in Figs. 8 to 11, inclusive, the scoop or shovel consists, preferably, of sheet-steel, having a fiat body 12 and curved sides 20, said sides being provided with eyes 21 for the reception of the hooks 22 of chains 23, said chains being connected by a ring 24:, to which the rope 11 is fastened. At the rear of the scoop or shovel are the handles 25, as shown. The pusher, as more fully shown in Figs. 5 to 7, inclusive, consists of a bent bar having strengthening-webs at 1ts angles, the upper rear surface of the bar being provided with rack-teeth 26 and its forward end in advance of the portion 27 being provided with a'pusher-head 28.
The operation of the apparatus is substantially as follows: The rope 11 being slack and the scoop or shovel being upon the floor of the mine or entry, as indicated in Fig. 2, the miner grasps the handles 25 of the scoop or shovel and pushes the latter in front of the body of coal to be loaded; Thereupon by means of a suitable lever 29, attached to the rheostat 80, the energizing-current is admitted to the motor, which thereupon begins to rotate. Accordingly through the intermediacy of the gearing 16 the rack 26, and with it the pusherhead 28, is advanced until the pusher-head engages the rear wall of the scoop or shovel and continuing to advance pushes the scoop or shovel into and beneath the body of blasteddown coal to the desired distance. The pusher is thereupon withdrawn by reversing the motor and is thrown out of gear by any suitable method. The drum 13 is 'now thrown into gear with themotor and winds up the rope 11, lifting the scoop or shovel, by means of the chains 23, to the height of the pitcar, the miner holding the shovel by the handles 25 and balancing the same. He then swings the shovel and beams 7 over the top of the pitcar and dischargesthe'c'oal from the shovel directly into said car. To enable him to do this with facility, the mounting for the apparatus as a whole consists of a turn-table 31, preferably revoluble upon ball-bearings, so as to be rotated upon the platform 1 by any appropriate means. Assoon as the contents of the shovel have been discharged into the car the shovel and beam are swung back again to any desired location, the motor is reversed, thereby permitting the shovel to descend, and the operation may be repeated.
So far as I am aware it is broadly new in mining-machines to load the coal into the pitcar, after it has been blasted down, by means of a machine-operated shovel, which after receiving its load is raised by machinery in such manner as to discharge its contents into the pit-car. It will therefore be understood that I do not limit myself to the particular construction of the apparatus shown, but contemplate also the employment of such equivalents therefor as fairly fall within the scope of my claims, which I desire may have an interpretation commensurate with the generic feature of novelty indicated.
Having thus described my invention, what I claim is 1. In a loading-machine for pit-cars, a shovel, suitable mechanism independent of the shovel for pushing said shovel underneath the coal, and suitable mechanism for raising the shovel and discharging its contents into the car, substantially as described.
2. In a loading-machine for pit-cars, a shovel, suitable mechanism for pushing said shovel underneath the coal, said mechanism consisting of a pushing-bar disconnected from said shovel and a motor for operating the same, and suitable mechanism for raising said shovel and discharging its contents, substantially as described.
3. In a loading-machine for pit-cars, a shovel, suitable mechanism independent of the shovel for pushing said shovel underneath the coal and suitable mechanism for raising said shovel and discharging its contents, said mechanism consisting of a hoisting-rope, a windingdrum for said rope and a motor for operating said winding-d rum, substantial], as described.
4t. In a lozuling-machine ior pit-cars, a shovel, suitable mechanism ind ependent oi the shovel for pushing said shovel underneath the coal and suitable mechanism for raising said shovel and discharging its contents, said shovel being provided with controlling-handles l'or steadying it during transit, substantially as described.
5. In a loading-machine for pit-cars, a freely-suspended shovel,a hoisting-ropev there for, and a motor-operated pusher for said shovel and independent thereof, substantially as described.
6. In a loading-machine for pit-ears, a freely-suspended shovel, a hoisting-rope tl ierefor, and a motorperated pusher for said shovel, said pusher having a rounded pusherhead, substantially as described.
7. In a loading-machine for pit-cars, a truck, a motor mounted thereon, a superstructure having an outwardly-extending arm, a hoisting-rope suspended from said arm, a hoisting-drum for said rope, a shovel depending from the hoisting-rope, and a pusher independent of the shovel adapted to force the same underneath the coal. substantially as described.
8. In a loading-machine for pit-cars, a truck having a turn-table provided with a superstructure having an outxardly-extemling arm, a hoisting-drum actuated by said motor, a hoisting-rope operated by said drum and depending from said arm, a shovel connected to said hoisting-rope and a pusher indepemlent of the shovel adapted to push said shovel underneath the coal, substantially as described.
In testimony whereof I aiiix my signature in presence of two witnesses.
GEORGE FRANCIS MYERS.
