Fl RE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 293,072, dated February 5, 18 4.

. Application filed Aprili, 1883. (No model.)

COOK, of Topeka, in the county of Shawnee and State of Kansas, haveinvented a new and Improved Fire-Escape, of which the following is a full, clear, and exact description.

The object of my invention is to provide an apparatus by which the escape of persons in any number from burning buildings can'be safely and rapidly accomplished, and by which invalids can also be easily removed.

The invention consists in a car suspended by a rope, combined with a ring having a pulley adapted to bear against the suspensionrope, and with a lever having a pulley also adapted to bear against therope, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similarletters of reference indicate corresponding parts in both the figures.

Figure l is a perspective elevation of the fire-escape applied to a building, and Fig. 2 is a section of i a car.

Upon the front of the building, and near the top, is firmly afiixed a bracket, A, extending out a distance sufficient to clear the car from obstructions, and on the bracket is a hanger, a, provided with a hook that receives a ring on the suspension-rope b. The car B, of suitable dimensions and form, is provided with a seat at its opposite ends, the space between being sufficient also for allowing persons to sit on the bottom of the car. At one end of the car, preferably beneath the seat, is a Windlass or drum, 0, supported in suitable bearings at each end, and provided with crank-handles d (I. At e, mid-length of the car, is a roller, and

the suspension-rope b, that? is wound around drum 0, passes beneath roller e, so that the car is suspended and properly balanced thereon.

f is a ring above the car, connected thereto by rods, ropes, straps,ror c hains g, rods being preferred, as they will prevent the ring dropping when the car rests on the ground. On the ring is attached anarm, h, carrying a erator holding the rod or handle at.

grooved wheel or pulley, t, that bears on the rope b, and at the opposite side of the ring is hung a lever, 7t, carrying at its inner end a grooved pulley, Z, bearing on the rope, either directly opposite or above or below roller '5. The pulleys may be plain, or else roughened to give more friction, and constitute a friction clamp or brake by which the car can be held in place while persons are entering, and by which the descent can be regulated.

On the outer end of the lever k is a rope,

strap, chain, or rod, m, for use by the operator in manipulating the lever, and to insure safety and prevent accident, which might occur in the confusion, I provide a rope, strap, chain, or rod, n, attached on the car, having a hook or catch on its end for catching aring on the handle m, so that the lever will be sesecurely held thereby until the car is loaded, when the rope a will be disconnected, the o'p- With these arrangements the car can be readily low ered, after being loaded, and when emptied of its load can be hoisted again by means of I claim as new, and desire to secure by Letters Patent, is-

g In fire-escapes, the combination of ring f, pulley z, lever 7c, and pulley Z, combined with the car and suspension-rope, substantially as shown and described.
