Improvements in connection with coal-cutting machines

240,614. Hurd, F. W. Sept. 2, 1924. Coal-cutting machines. - A coal-cutting machine has a gear head carrying the turntable, a driven gear and gear-head shaft within and carried entirely by the gear head, a motor-driven shaft carrying a pinion in mesh with the driving gear, a cutter actuating member with bearings therefor carried entirely by the turntable and a flexible driving connection between the driven gear and the cutter actuating member. In a chain machine the motor shaft 1, 2 is divided at the gear head, the parts being automatically connected by a centrifugal clutch 3, 4, on starting of the motor, while a member 5 may be moved by a lever 6 to disengage the clutch. The shaft section 2 is supported in bearings 2<a> 2<b>, and carries a bevel gear 8 meshing with a crown wheel 9 fixed to a hollow shaft 10 entirely supported in the gear head 11, which may be split vertically. A turntable 14 carries the jib and entirely supports the chain driving sprocket 12 which is connected to the shaft 10 by a hexagonal, square, splined or castellated shaft 13 engaging corresponding bores in the parts 10, 12 and having sufficient freedom to avoid non-torsional stresses. The shaft 13 may be lifted by hand or screw means to interrupt the drive of the sprocket 12 &c. The turntable 14 has a bevel rack 15 engaged by bevel pinions 16, driven manually or from the haulage gear to slue the jib; a toothed segment 17 connected to a screw 18 may be moved by means of a rotatable nut 19 to engage the rack 15 to lock the jib. The construction may be modified for use with cutter-bar machines.

331,212. Sullivan Machinery Co. Jan. 11, 1929, [Convention date]. Coal-cutting machines.- A coal-cutting machine comprises a body with a rotatable cutter-head carrving a pivoted cutter-bar, and means for swinging the cutter-bar about its pivot in any position of adjustment of the head, the means including a member adjacent to the head and rotatable relatively thereto and about the axis of rotation thereof, and connections between the member and the cutter-bar. The same means is also adapted to adjust the cutter-head. As shown, the cutter-bar 34 is adjustably supported on an annular flange 43 on the cutter-head 5, and the latter is supported rotatably by a sleeve 23 surrounding a bearing-sleeve 16 extending from the motor casing 4. A worm-wheel 131 loosely surrounds the sleeve 23 and is fixed to a chain wheel 133; a chain 134 engages the chain-wheel and passes round guide sprockets 135 on the cutter-head and round a groove 137 on the cutter-bar supporting member 39. Locking-members 140, Fig. 5, operated by screws 141 are adapted to lock the sleeves 23, 16 together, and a boss 144 on the member 39 carries a locking-member 142, Figs. 3 and 6, adapted to be forced by a screw 146 into engagement with the chain 134 and a locking- member 148 adapted to be forced by a screw 147 into engagement with the cutter-head. To swing the cutter-bar, the locking-means 140, 142 are applied to lock the cutter-head and to lock the cutter-arm to the chain 134, and the latter is driven; to rotate the cutter-head, the locking- means 142, 148 are applied to lock the cutter-bar to the chain and to the cutter-head, locking- means 140 are freed and the chain is driven. The worm-wheel 131 operating the chain is driven through a worm 130, chain 126, a further chain parallel with the chain 117, and a clutch 121, Fig. 7, from a transverse hollow shaft 102 which is driven through reversing bevel gearing 98, 99, 100 and variable-speed reversing gearing as in Specification 277,621.
