Revendications

Claim lst. In a hoisting machine, in which the motion of the axle is conveyed to the rope drum by a friction clutch, a disc E having a flange s extending at right angles from its surface a short distance below its periphery, in combination with a series of wooden blocks f arranged endwise around the flange e and securely bolted to the disc, the said blocks being bevelled from the periphery of the die d towards the outer edge of the flange e, substantially as and for the purpose specified. 2nd. In a hoisting machine, in which the motion of the axle is conveyed to the rope drum by a friction crutch, a disc E having an octagonal flange extending at right angles to its surface a short distance from its periphery, in combination with a series of wooden blocks arranged endwise around the flange, one block for each octagonal side, the said blocks being securely bolted to the diso and bevelled off from the periphery of the disc towards the outer edge of the flange, substantially as and for the purpose specified. 3rd. In a hoisting machine, in which the drums are journalled on the driving axle, a disc or discs E keyed to the said axle and having an octagonal flange e extending outwardly from its periphery, with block of wood arranged around the disc and bolted to the octagonal sides, the said blocks being bevelled as shown, in combination with the drum C journalled on the axle A and having a conically-recessed head, to fit over the bevelled flange e, with mechanism for adjusting the drum longitudinally on its axle, substantially as and for the purpose specified. 4th. In a hoisting machine; a disc E keyed to the axle A and having an octagonal flange e extending outwardly from its periphery, with block of wood arranged around the disc and bolted to the octagonal sides, the said blocks being bevelled, as described, to fit into the conically recessed head D of the drum C, which is journalled on the axle A. m'combination with a key fitting into an elongated key-way made in the axle A at the outer end of the drum C, and actuated by a screw arranged to butt against a spindle fitting into a hole extending from the end of the axle to the key-way, substantially as and for the purpose specified. 5th. In a hoisting machine, in which the rope drum is adjustably connected to its axle by a friction clutch formed by the end of the drum being brought in contact with a disc keyed to the axle, the said adjustment of the drum being effected by a spindle and screw through a nut in the frame and acting against the end of the drum, an arm 0 fastened to the outer end of the screw, in combination with a rookshaft Q journalled in the frame of the machine and connected to the arm 0, substantially as and for the purpose specified. 6th. In`a hoisting machine, in which the rope drum is journalled on its axle and derives motion through a friction clutch adjustably connecting it to a disc keyed to the axle, a pinion fastened to the drum and gearing, with a wheel journalled on a counter-shaft, the face of the disc being conically recessed to fit over an inversely-shaped flange on a disc keyed to the counter-shaft, in combination with a pinion also fastened to the counter-shaft and gearing with a wheel keyed to the axle, the connection between the loose and tight discs on the counter-shaft being adjustable so that the rope drum may be driven or at by the gearing specified, substantially as and for the purposes specified. 7th. In a hoisting machine, - in which the rope drum is adjustably connected to its shaft by a friction clutch, a counter-shaft having a pinion keyed to it, which pinion gears with a larger wheel keyed to the rope drum's axle so that the counter-shaft shall revolve at a higher speed than the axle, a gear wheel F journalled on the counter-shaft and engaging with a pinion fastened to the rope drum, in combination with a friction connection formed between tilt gear wheel F and countershaft and operated by a cam, substantially as and for the purpose specified. 8th. In a hoisting machine, a friction clutch formed by a conically recessed disc having a paper lining pressed into it, in combination with metal disc having a conical formed on it to fit into the paper-lined disc, as specified. 9th In hoisting machine, in which the rope drum is so connected to its shaft that it may revolve freely on it, the combination of speeded, gearing arranged to connect the rope drum to its Shaft, so that the speed of the drum Shall be greater than its shaft, the said gearing being provided .with clutches so that the connection between the drum and shaft may be disconnected at pleasure.
