HOIST.
SPECIFICATION forming part of Letters Patent No. 626,868, dated June 13, 1899.
Application filed June 22, 1898.
T0 aZZ whom, it nuty concern:
Be it known that I, ALEXANDER B. RONEY, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Hoists, of which the following is a specification; 7
The object of myinvention is to so balance the load in hoisting apparatus as to be selfsustaining. I attain this object by mechanism, as illustratedin the accompanying drawing,in which the figure is aview in elevation of all the working elements of the device.
Within the standard E is a lazy-tongs S, having links pivotally connected together and a stationary pivot connecting the lazytongs to the standard at J. The lazy-tongs S is adapted to be folded up and spread apart when operated,but none of the various means for the operation are shown in the view, save the hand operating-stud K. The lazy-tongs S is connected at LL with the terminals 0 C of the cable, which passes over the directional sheave-wheels A A A A and D, hanging with a loop embracing the sheave-wheel B,
Serial No. 684,190. (No model.)
which sustains the weight H. Weight H causes a strain on the cable, which divides along both sides 0 O of the loop, thence to the lazy-tongs at the pivotal connections LL, and there straining and counterstraining the extension of the lazy-tongs in maintaining the weight 11 in suspension. The lazy-tongs connected with the looped cable constitutes an endless system, which is shortened up to raise and lengthened out to lower the weight H.-
What I claim as my invention, and desire to secure by Letters Patent, is
In a hoist, in combination, a standard, a lazy-tongs having links pivotally connected together, and a stationary pivot connecting the lazy-tongs to the standard, and a cable having a loop andhaving one of its ends con nected to one of the pivotal connections of the lazy-tongs, and its other end to another one of the pivotal connections of the lazy tongs; substantially as described.
ALEXANDER B. RONEY.
