MACHINE FOR WORKING COAL OR OTHER MINERALS.

SPECIFICATION forming part of Letters Patent No. 488,606, dated December 27, 1892.

been patented to us in Great Britain, No.

1,014, dated January 23, 1888,) of which the following is a specification.

This invention relates to improvements in machinery for cutting, or working coal, or other mineral, and has for its object the pro vision of means for undercutting the coal, or other mineral, at the bottom of the seam, the cutter, or drill, being kept as low as possible so as to insure the least waste of the coal, or other mineral, to be worked.

To allow this invention being carried into effect the cutter, or drill, is suitably coupled to, or may form part of a shaft which rotates in a long bearing hung from a center about which it may swing in a horizontal, or nearly horizontal, plane. The same center serves also to carry a vertical shaft having a bevel wheel and this engaging with a similar bevel wheel, on the rotating cutter shaft, admits of motion being transmitted to the cutter shaft in any position in the horizontal plane. The shaft to which the cutter is attached is preferably carried by its bearing, under a table, or frame, mounted on wheels so as to run on the usual trams, or rails, and supporting the prime mover, or source of power, such as an electric, steam, or air motor, or rope wheel, and may be arranged so as to only just clear the rails on which the table, or frame, travels. The center, or trunnion, about which the cutter shaft rotates, in the horizontal plane, may

preferably be carried in front of the table so as to allow of cutting being effected on either side of the table or at any intermediate point in the are described by the rotation of the cutter bar in a horizontal plane. When the prime mover is an electric, steam, or air motor, it may remain fixed, horizontally, upon the table, or frame, and transmit its motion to the vertical shaft, which in turn imparts motion to the cutter bar by a second pair of bevel wheels.

To allow of the cutter bar being fed forward to its work, when working with its axis at right angles to the rails on which the table,

or frame, travels, it may be formed as'a square bar, or provided with a sufiiciently long feather key so as to allow of its being fed forward, by a screw, or other device, axially through the bevel wheel by which motion is imparted to it; or the table, or frame may be so constructed as to allow of that part of it which supports the trunnion, or center, and the long bearing in which the cutter shaft r0- tates, being traversed in a direction at right angles to the rails on which the table, or frame, runs, or similarly the whole top of the table, or frame, may be made to so traverse.

Having now set forth the nature of our invention and shown in what manner the same is to be carried into effect we will now proceed to more particularly describe the same by reference to the accompanying drawings.

Figure 1 is an end elevation and Fig. 2 a side elevation of a coal cutting machine constructed in accordance with this our invention.

Suitably mounted on the frame, or table T is an electro motor M the spindle A of whose armature imparts motion by means of the bevel wheels 5, Z), to the vertical spindle d. This vertical spindle d is provided at its lower end with a bevel wheel, as shown in Fig. 1, which in turn imparts, by means of a secon l bevel wheel, motion to the drill, or cut 'ter, shaft D, carried in the long bearing E and attached by the coupling 0, c, to the drill, or cutter, O. The long bearing E is cast or otherwise formed with the vertical sleeve piece F which passes through and is supported by the bracket B suitably secured to the frame or table T. The sleeve piece F is provided with the toothed wheel I and the worm J on the spindle of the hand-wheel H engaging with this toothed wheel I allows of its being rotated and so causing the long bearing E, and with it the drill, or cutter, O, to be rotated in a horizontal plane.

The electro motor together with the whole of the working parts, is inclosed in a dust tight casing 15, t, as shown.

Having now particularly described and ascertained the nature of our said invention, and in what manner the same is to be performed, we declare that what we claim is:-

1. In combination the carriage, the vertical shaft at one edge thereof, the bearing therefor the cutter shaft extending transversely across the lower end of the vertical shaft, the gearing between said shafts, the long bearing for the end of the cutter shaft extending laterally in line therewith said bearing having a sleeve extending upwardly through and above the bearing for the vertical shaft and about the said shaft, and means connected with the upper exposed end of the sleeve for turning the long bearing and the cutter shaft to different lateral positions and the means for operating the vertical, shaft,

substantially as described.

2. In combination the carriage frame, the vertical shaft at one edge thereof the cutter extending below the same the long bearing for the cutter shaft having a sleeve extending upwardly about the vertical shaft through
