HOIST FOR COAL-MINES.

Specification of Letters .Patent. Patented NO 13, 1917'.

Application filed March 7, 1917. Serial No. 153,035.

To all whom it may concern:

Be it known that I, ARTHUR APPLEYARD, a citizen of the United States, and a resident of Beaverdale, county of Cambria, State of Pennsylvania, have invented certain Improvements in Hoists for Coal-Mines, of which the following is a specification.

My invention relates to certain improvements in the means for handling miners cars in coal and other mines.

One object of the invention is to avoid the expense incident to removing rock other than coal in order to render the galleries of sufiicient depth to admit of the movement of mules or electric locomotives.

Another object of the invention is to design the mechanism so that it can be worked in galleriesin which the seams of coal are very narrow. I I v Stillanother object of the invention is to operate the carsindependently in the several galleriesand to rovide electric mechanism by which the hoist can be actuated at any point in the gallery.

In the accompanying drawings:

Figure 1 is a perspective view showing one of the mine galleries partly broken away and illustrating my invention;

Fig. 2 is a plan view showing the two galleries and the independent mechanism for each gallery; and i Fig. 3 is a side view of my improved hoisting mechanism. 7 g

This invention relates particularly to the mechanism for handling the cars in coal mines and mines having comparatively narrow veins. It has been the general practice to cut the coal in the veins in order to increase the depth of the gallery and to cut away the stone to a suflicient depth to allow for the passage of the mules or an electric car into the working gallery from the main gallery. This extra cutting is waste and is exceedingly expensive as the-stone is harder than the vein of coal and must be loaded on cars and removed to the surface.

By my invention, I am enabled to reduce. the height of a working gallery and in many instances not cutting beyond the depth of the vein of coal, the height being suilicient to allow a man to work and the ordinary type of car to be drawn into and out of the working gallery.

A is the main gallery and B, B are two of the series of working galleries and the length of these galleries depends considerably upon the vein of coal and the width will vary under ordinary conditions. There are usually comparatively large pillars C at the main gallery between each working gallery, as shown.

l is the main track extending through the main gallery and leading to tracks connected to the surface or with elevators, according to the type of mine. 2, 2 are the temporary tracks extending into theworking galleries B, B. 3 are the switches for driving the car from the main track onto the working tracks 2. 4 is the car adapted to the tracks 1 and2, and this car is loaded by a miner in the working gallery and when it passes onto the main track 1 it is drawn out by mules or a locomotive, as it will be understood that the main gallery is of a greater height than the working gallery in the ority of cases. The floor of the working gallery is usually inclined, the grade being such that when the car in the working gallery is released it will travel by gravity out of the gallery and onto the main track. The great difficulty has been'to provide means for taking the car into the farther end of the gallery where'the work is being done.

At one side ,of the track Zin each gallery is a hoisting apparatus 5 consisting of a drum 6' mounted in suitable bearings 7 and an electric motor 8 geared to p the drum through gearing 9 and 10. Mounted on the drum is a rope 11 in the present instance extending around a guide wheel 12 and around a pulley 13 at the extreme end of the gallery. The pulley 13 is mounted on a strut 14lsecured to the floor and ceiling in the ordinary manner and the wheel 12 is alsocarried by a strut 15. At the end of the rope 11 is a hook 16, which engages a pin 17 on the car 4 so that when the hook is in engagement with the pin and the motor is driven inone direction the drum will con 'the'rope and drag the car to the point desired.

In order to enable a miner to handlethe 'car. properly without having to go to the hoisting mechanlsm I provide an electric switch 18 connected by wires to the motor 8 in the ordinary manner so that on operating this switch the miner can cause the car to traverse the track to any point desired. This switch is mounted on a post 19 held in position in any suitable manner, or it can be mounted on a temporary post and shifted from place to place. The wires, however, are preferably arranged overhead so that the operator will not come in contact with them.

In order to prevent the racing of the drum, when the rope is slack, I-providean automatic brake pivoted at 21 to a strut 22 and this brake has a shoe 23 which bears against the drum and has, at its outer end, a grooved Wheel 24-, which rests on the rope so that the moment the rope becomes slack the brake will come in contact with {the drum 6, but, as soon as the rope is taut again, it will raise the brake lever 20 and its shoe 23 clear of the drum. :The hoisting mechanism is temporarily held inposition by jack pipes 25 which extend to the roof. I have shown three jack pipes, bu t it :Will be understood that any number can be used, as desired.

The operation is as follows:

lVhenthe working galleries are started, the opening ,isanade and the temporary track partly laid and connected. to the main track. After the working has been made to a certain depth, then the hoisting mechanisni is located in position at one side of the traek, as shown, and at the entrance of theavorking gallery. A strut is placed at the extreme inner end of the .workand the rope is passed around the pulleys, as shown, so that whena car. is brought to the entrance of a working'galleryflt is conpledto the rope, and by operating the vswitch mechanism the drumis set in motion and thel car is hauled up the slight ineline and,intothe gallery to the point where the'miner is working. It is held i-n;thi s position until it isfilled, then thedrum is released and the car returns by gravity to thesentrance f h VO -g, i dthe driver inathe nain gallery will nncouple the rope allowing the car to pass onto the track in themain gallery. The empty car wi-ll be broughtinto position and coupled to the rope. The miner will again operate the switch and the empty car vvillb'e drawn np ,into position in the working gallery. Some ofithese galleries are comparativelyl ong and considerable time is usnally wasted by the miner go ng h f ng h of th .gall ry to operate hi ca Whe eas, .by y impr ment', the minercan devote his entire time to mining coaland loading the ears.

y this a rang en c r al v isi dependent of the others, so that one miner does not have to Walt upon others for power mechanism for handling his cars and the .use ofmules and (BXPQIISHG; electric locomotives are entirely dispensed with in the working galleries.
