C. S. WATSON.

FIRE BSGAPE.

Patented Dec. 1, 1885.

(No Model.)

UNITED STATES PATENT rrrcE.

CHARLES S. WATSON, OF PHILADELPHIA, FENNSYLVANIA, ASSIGNOR OF ONE-HALF TO ISAAC TOWNSEND, OF SAME PLAGE.

FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 331,746, dated December 1, 1885,

Application filed May 7, 1585. Serial No. 164,656. (No model.)

To all whom, t may con/cern.-

Be it known that I, CHARLES S. WATSON, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Fire-Escapes, which improvement is fully set forth in the following specification and accompanying drawing.

The figure is a side elevation of a tireescape embodying my invention, which consists of a stock having an eye at each end, and a rope which is passed through the eyes and wound around the stock, whereby when a body strap or belt is attached to the lower eye a person may safely use the escape, the vfriction created preventing rapid descent of the person.

Referring to the drawing, A represents a bar or rod, which I denominate a stock, and B represents eyes at the ends thereof.

O represents a rope,which is passed through the upper eye, then wound around -the stock, and next passed through the lower eye, said rope having a hook, I), whereby it may be readily attached to a window-sill or other proper place, and when thus attached the sling, strap, or belt of the person using the escape is connected with the lower eye, and he permits himself to descend, it being seen that the eyes and stock produce friction,which prevents rapid action of the escape or running away of the sanne.

The extent of friction may be adjusted by properly manipulating the rope so as to increase or deereascthe numberof coils or windings of the rope around the stock.

Each end of the rope has a hook, D, which is constructed of a bar of metal bent so as to forni an eye, having two lengths of metal and two prongs or forks spreading or flaring, and the ends thereof curved and pointed, substananother one in the building may hoist the 5o rope and avgoid the labor and loss oi' time occasioned by unwinding or nncoiling the rope from the stock, the upper hook then being released, the lower hook suitably engaged, and

the proper part of the rope dropped, after 55 which a body sling, strap, or belt is attached to the lower eye, and thus the escape may again be used, and there may be further use of the saule, as is evident.

Having thus described my invention, what 6o I claim as new,and desire to secure by Letters Patent, is-

l. A iire-escape provided with a rope having at each end thereof a hook having two flaring and pointed prongs, substantially as and 65 for the purpose set forth.

2. A fire-escape consisting ofa stock having eyes at each end thereof, and a rope having a hook at each end, each hook having an eye and double flaring points, substantially as 7o and for the purpose set forth.

3. A fire-escape consisting of' a stock having an eye at each end, and a hook formed of an eye and two prongs, the eye being of two lengths of metal bent from the prongs, sub- 75 stantially as and for the purpose set forth.
