'WILLIAM E. SIMPSON, 0F DETROIT, MICHIGAN.
HOIST.
Application filed August 27, 1920. Serial No. 406,303.
T 0 all whom it may concern Be it known that I, VILLIAM E. SIMPSON, a subject of the King of Great Britain and Ireland. residin at Detroit, in the county of Wayne and tate of Michigan, have invented certain new, and useful Improvements in Hoists, of which the following is a specification, reference being had therein to the accompanying drawings;
The invention relates to hoists and has for its object the provision of a connection between the flexible hoisting element and the hoist drum or sheave which is secure and at the same time is easily detachable when required for 'renewal or repair. Other objects of the invention reside in features ofconstruction as'more fully hereinafter set forth.
In the drawings:
Figure 1 is a side elevation of a portion of a construction embodying my invention;
Figure 2 is a longitudinal section therethrough;
Figure 3 is a cross section on line 33 of Figure 2.
1 is the flexible hoisting element, a rope in the present instance, and 2 are the grooves extending in the usual helical form along the face of the hoist drum or she-ave 3. These grooves terminate at one end in a continuous circular groove 4 of extra depth, the bottom of this groove being a spiral convolution and its inner end terminating in a wedge shaped recess or pocket 5. 6 is a block secured to the live end of the hoisting element 1, this block being wedge, shaped similar to and adapted to fit Within the recess or pocket 5. The depth of the groove 4 is preferably such that when the block 6 is placed within the recess and the rope coiled twice around upon itself, the rope will be then at a pitch radius,- or a distance from the axis of drum or sheave, equal to the pitch radius of the helical grooves along which it then continues to coil in the usual manner. Thus, the block 6 is held securely in place and at the same time can be easily removed by rotating the drum or sheave through several turns beyond its usual limit of move ment.
What I claim as my invention is:
1. Ina hoist, the combination with a Winding drum, of a flexible hoisting element, a spiral groove in said drum adapted to receive a plurality of convolutions of said element and terminating in a recess, and an enlarged portion on said flexible element adapted to engage in said recess, said enlarged portion being insertable into said lQCOsS from the exterior of said drum and being adapted t be secured therein by a. convolution of said flexible element in said :XTOOVQ.
2. In a hoist, the combination with a winding drum, of a flexible hoisting element, a continuous circular groove in said drum, of a depth to receive a plurality of convolutions of said hoisting element, the bottom of said circular groove being a spiral convolution and its inner end terminating in a wedge-shaped recess, and a wedgeshaped' member attached to an end of said hoisting element and adapted to fit within said recess, said wedge-shaped member being insertable into said recess from the exterior. of said drum and being adapted to be secured therein by a surrounding convolu-- tion of said hoisting element in said circular groove.
3. In a hoist, the combination with a winding drum, of a flexible hoisting element, a helical groove in said drum, a continuous circular groove insaid drum connecting into said helical groove and adapted to receive a plurality of convolutions of said flexible hoisting element, said circular groove having a recess therein, and an enlarged portion attached to said flexible hoisting element and adapted to engage in said recess, said enlarged portion being insertable into said recess from the exterior of said drum and being adapted to be secured therein by a convolution of said flexible hoisting element in said circular groove.
4. In a hoist, the combination with a winding drum, of a flexible hoisting element, a helical groove in said drum, a continuous circular groove in said drum of greater depth than said helical groove and connecting thereinto, said circular groove being adapted to receive a plurality of convolutions of said hoisting element, the bottom of said circular groove being a spiral convolution and its end terminating in a recess, and an enlarged end of element adapted to engage in said recess said enlarged end being insertable into said recessfrom thevexterionof said drum and being adapted to be secured therein by a surrounding convolution of said hoisting element in said circular groove;
In a hoist, the combination with a said hoisting winding drum, of a flexible hoisting element, an annular groove in said drum of a depth to receive a plurality of convolutions of said hoisting element and provided with a recess, and an enlarged portion on said hoisting element adapted to be inserted into said recess from the exterior of said drum and to be secured in said recess by a convolution of said hoisting element 111 said annular groove. 10
In testimony whereof I affix my signer ture.
