Triple action mechanical chute-hoist

Claim 2

Apparatus for descending and ascending a cable comprising: a reel member having a central portion disposed about a rotation axis and onto which said cable can be wound, an integral first end portion forming a braking surface extending cylindrically about said rotation axis from said central portion, and an opposite end portion adapted for cooperating with centrifugal brake means disposed about said rotation axis and extending oppositely from said central portion, a stationary frame, means for mounting said reel member in said frame for rotation to pay out or wind said cable, centrifugal brake means including a stationary frame portion opposing said end portion and brake shoe means carried by said opposite end portion of said reel member for rotation therewith to engage said stationary opposing frame portion and brake said reel member during rotation thereof, the braking force being a function of the speed of rotation, actuable brake means mounted on said frame for engaging said braking surface of said first end portion of said reel means to retard or stop rotation of said reel member, manual control means coupled to said actuable brake means for operating said actuable brake means to stop rotation of said reel member, and ascend means engaging the reel member to rotate the reel member and wind said cable onto said reel member to ascend said cable.

Claim 3

Apparatus as in claim 1 wherein said reel member has a portion with teeth extending circumferentially about said reel member and said ascend means comprises a gear member engaging said teeth, a crank arm fixedly attached to said gear member for rotating said gear to wind cable on said reel member and means mounting said crank arm in said frame for rotation.

Claim 4

Apparatus as in claim 1 wherein said actuable brake means is manually operable and includes a pair of brake shoes, means pivotably mounting said brake shoes, spring means urging said brake shoes out of engagement with adjacent surfaces of said reel member, an actuating member having a rest position and an actuating position in which said actuating member engages said brake shoes against the urging of said spring means to force said brake shoes against said adjacent surfaces of said reel member to brake said reel member and wherein said manual control means includes a grip member and a wire connected between said grip member and said actuating member.

Claim 5

Apparatus as in claim 3 wherein said centrifugal brake means includes a pair of centrifugal brake shoes mounted on said opposite end portion of said reel member for rotation therewith, and spring means urging said centrifugal brake shoes out of engagement with said frame portion.

Claim 6

Apparatus as in claim 1 further including said cable.

Claim 7

Apparatus as in claim 1 wherein said further brake means comprising said centrifugal brake means.

Claim 8

Apparatus for descending a cable comprising: a reel member having a central portion disposed about a rotation axis and onto which said cable can be wound, an integral first end portion extending from said central portion and forming a braking surface extending cylindrically about said rotation axis, and an opposite end portion extending oppositely from said central portion adapted for cooperating with centrifugal brake means disposed about said rotation axis, a stationary frame means for mounting said reel member in said frame for rotation to pay out or wind said cable, centrifugal rotating brake means including a stationary frame portion opposing said opposite end portion and brake shoe means carried by said opposite end portion of said reel member for rotation therewith to engage an opposite stationary frame portion during rotation thereof and brake said reel member, the braking force being a function of the speed of rotation, manually actuable brake means for engaging said braking surface of said first end portion of said reel means to retard or stop rotation of said reel member, including a brake shoe member, means pivotably mounting said shoe member adjacent said braking surface, means urging said brake shoe member out of engagement with said braking surface, and actuating means engaging said brake shoe member and rotatable to pivot said shoe member into braking relation with said braking surface, and manual control means coupled to said actuable brake means for rotating said actuating means to retard and stop rotation of said reel member.

Claim 9

Apparatus for descending a cable comprising: a reel member having a central portion disposed about a rotation axis and onto which said cable can be wound, an integral first end portion extending from said central portion and forming a braking surface extending cylindrically about said rotation axis, and an opposite end portion extending oppositely from said central portion adapted for cooperating with centrifugal brake means disposed about said rotation axis, a stationary frame means for mounting said reel member in said frame for rotation to pay out or wind said cable, centrifugal rotating brake means including a stationary frame portion opposing said opposite end portion and brake shoe means carried by said opposite end portion of said reel member for rotation therewith to engage an opposite stationary frame portion during rotation thereof and brake said reel member, the braking force being a function of the speed of rotation, manually actuable brake means for engaging said braking surface of said first end portion of said reel means to retard or stop rotation of said reel member, including a brake shoe member, means pivotably mounting said shoe member adjacent said braking surface, means urging said brake shoe member out of engagement with said braking surface, and actuating means engaging said brake shoe member and rotatable to pivot said shoe member into braking relation with said braking surface, and manual control means coupled to said actuable brake means for rotating said actuating means to retard and stop rotation of said reel member.
