HOISTING APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 681,135, dated August 20, 1901.

Application filed May 8, 1901.

To all whom it may concern: i

it Be it knownthat I, WESLEY A. PETREE, a citizen of the United States, residing at Mizpah, in the county of Stokes and State of North Carolina, have invented certain new.

and useful Improvements in Hoisting Apparatus; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for hoisting meats, &c., and transferring the same to hooks which are held to stationary beams of a store-room and it consists in the provision of pulley-blocks, each of which contains a double pulley made of a single piece of ma terial mounted upona spindle and journaled in a suitable yoke, said pulleys carried by separate yokes being connected by means of hoisting-ropes, and the provision of a hook, which is mounted upon a rope which is fastened at its upper end to a stationary beam and adapted to receive a beef or other carcass, which is raised by the double pulley to pulley-blocks. Fig. 3 is an edge elevation,

and Fig. 4 is an end view showing the guards on the pulley-block or yoke.

Reference being had to the details of the drawings by letter, A designates a double pulley made of a single piece of metal or wood having a grooved circumference A about its largest diameter and a groove 13 about the contracted or smaller portion of the pulley, the diameter of the grooved portion A being substantially twice that of the grooved portion B. A spindle 0 passes centrally through said pulley block and is journaled in Serial No. 59,263. (No model.)

the arms D and D of the yoke E. Said arms are angled, as shown, forming guards to hold the ropes in their respective grooves, and secured to or integral with each yoke E is a hook E, which is adapted to engage a ring F, which is secured to a yoke G in a rope which is fastened about the beam H, which is held near the ceiling of the store-room. A similar pulley K, which is double, is journaled in a yoke K and provided with a hook which is adapted to engage the stick N, which is fastened to the carcass tobe elevated. At intervals along the beam K are fastened the ropes J, to the lower ends of which are fastened hooks L, on which the carcasses which are hoistedare transferred when elevated to a sulficient height. I

Upon referring to the detail views it will be observed that each yoke E has the integral guard projections B, there being four of these on opposite sides of the pulley, whereby the ropes which pass about the grooved portion of each pulley are held in said grooves.

A rope S has one end secured to the stationary beam H and passes downward underneath the small grooved portion ofthe pulley K, thence upward and over the contracted and grooved portion of the pulley A, thence downward and underneath the large grooved portion of the pulley K, then upward and over the large grooved portion of the pulley A, and has its free end disposed at a suitable location, whereby the rope may be gripped when it is desired to hoist the carcass of beef or other meat which has been previously caught over the hook at the lower end of the yoke K. By pulling down upon the end of the rope thus arranged over the pulleys it will be observed that a large weight may be hoisted with a small expenditure of power. When the weight is raised to a sufficient height, one of the hooks L, suspended from the rope J, may be moved along adjacent to the hook on the yoke K and the weight transferred to the hook L.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-

An apparatus for hoisting meats, 850., comprising two double pulleys having grooves of two different diameters therein, a yoke and spindle carried by each, on which the pulley is journa1ed,. guard members integral with; said yokes and adjacent to the ;grooves in; said pulleys, each of said yokes having an angled portion projecting over the contracted grooved portion of the pulley, the hook on the yoke, a ringsecured to a stationary beam engaged by said-hook,-a-rope anchored atone end to said beam and passed about the two pulleys similarly constructed, and-a :stationary xo hook suspended from said beam on which the meat .or other substance or article being hoisted may be trans'ferred,as.,shown and described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

WESLEY A. PETREE.
