WATER ELEVATOR.
No. 61,137. Patented Jan. 15, 186 7.
Quint! giant. isms: @ffitz- W. E. BABCOCK, OF EAST PEMBROKE, NEW YORK.
Let ers Patent No. 61,137, dated January 15, 1867'.
v tits same woman flgrse jicttcrsfifiiteut m nailing part at tlgc time.
TOQALL WHOM IT MAY, oononnsa Be it known that I, W. E; BABCOCK, of East Pembroke, in the county of Genesee, and State'cf New York, have invented a newand useful Improvement in Windlass Elevator for raising water and other purposes; and I (lo-hereby declare that the following is a full, clear, and exact description thereof. 7
The object of this invention is to provide a safe anddurable method for raising water from wells and for other purposes; and it consists in arranging'a drum upon a shaft in such a manner that while itis entirely secure from accident while the weight is suspended from it, a slight reverse movement of the crank sets it 'free and allows the bucket or weight to descend without turning the crank, and as rapidly as may be desired.
To enable others skilled in the art to make and use my invention, I will proceed'to describe its construction jand operation, reference being had to the accompanyingdrawings, forming apart of this specification, and'to the letters of reference marked thereon.
Figure 1 represents a vertical sectional elevation.
Figure 2 shows an end view; and
Figure 3'represcnts a top view.
Similar letters of reference indicate like parts in, the drawing. p
A represents the drum of the Windlass; B is the shaft; C the hca-d piece'o'f the rlrum, and C the piece that forms the nut-and journal and cone, and upon which is the ratchet. D represents the'frame which supports windlass; E represents the pawls, F the rope or chain, and the weight to be raised. C and C form friction cones, and the friction produced by a. movement of the cone G into cone or cavity e, in the head of the drum, is suflicicn t tehold the drum in any position and to raise any-weight required. The drum A revolves loosely on the shaft B when the'w eight is descending and when there is no friction in the" cones. The drum bears where the shaft passes through the head C. portion of the head e forms the flange to confine the rope to the drum, and the cavity or inverted conein the end receives the cone on e, the outside of e and the inside of c being of. the same taper. The piece C extends to thebutside of the frame D, the outer portion, h, forming the bearing upon which rests the weight of the whole apparatus. 1his bearing his hollow nearly its whole length, but inside of the bearing and hollow portion a screw-thread is 01111;!) right-hand screw at one endand a left-hand screw at the other. The inner portion of C is hollowed out and contains a spiral spring, which operates against the head of the drum and is useful in raising lightweig hts. The. outeredge or periphery bf the piece e" forms a ratchet-wheel in which the ratchet-pawls' E work, they being attached to'the frame D. The shaft B has the crankf upon one end, and screw-threads are out upon each end, aright-hand thread (in one end and a lefthand thread upon the other, which work inthe right and left-hand screw-threads cut in e. When the shaft is rcvolved, the efi'ect .is to bring the cone-pieces C toward each other, through the action of the right and lefthanded screwsya backward movement of the crank throws them from each other. The first movement would of course bring the cones in contact with each other and carry round the drum; the backward movement would as surely liberate the drum. Now, when the forward movement of. the crank brings the cones into contact the I screws will keep operating and press them together until the friction is suflicient to carry the drum along with the shaft, and this friction is greater or'less according as the weight to be raised is more or less. There might be a ratchet upon thefiange of the drum, and a. pawl to work in it, for the purposeof: holding the weight at any desired point. But in my present arrangement thisobject is accomplished by disengaging one of the pawls E from the ratchet on C. When that is done, and the weight moves the drum, the'disengaged ratchet will move with'it and tighten the drum. The same effect might be produced by using but one. cone and allowing the other to be fast to the shaft, and the Windlass could be constrhcte'd in this manner if desirable. It is not considered necessary to particularlydescribe the frame -D, as there is nothing peculiar in its construction. The shaftand hearing are secured to it in the usual manner by boxes and caps, and the pawls are screwed or boltedto the inside, where they drop into the notches of the ratchet by their own weight. v
' Having thus described my invention, what I claim as new, and-desire to secure by Letters Patent, is'- The drum A, the shaft B, the head 0, the ratchet-cone e, and the spiral spring 0, when arranged and combined substantially as described for the purposes herein set forth.
