FREDERICK G. FRISHKORN, OF PITTSBURG, PENNSYLVANIA.

FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 716,835, dated December 23, 1902.

I Application filed March 8, 1902. Serial No- 97,294- (No model.)

To all whom it may con/corn.-

Be it known that I, FREDERICK G. Fnrsn- KORN, a citizen of the United States, residingat Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Fire-Escapes, of which improvement the following is a specification.

This invention relates to certain new and useful improvements in fire-escapes, and has for its object the provision of novel means whereby a cage may be easily raised and lowered and adjusted to any height desired on a building.

Theinvention further aims to provide novel means that can be rigidly attached or secured to a building; furthermore, to construct a device that will be highly efficient in its operation.

Another object of the invention is to construct a device of the above-described charactor that will be extremely simple, strong, durable, and comparatively inexpensive to manufacture.

WVith the above and other objects in view the invention consists in the novel combination and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claim.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate corresponding parts throughout both views, in which Figure l is a front elevation of a buildinghaving secured thereto in position my improved fire-escape. Fig. 2 is an end view of a portion of a truck carrying a Windlass for operating the same.

In the drawings the reference-numeral 1 indicates a building having secured to the roof thereof hangers 2.

The reference-numeral 3 indicates a rope operating over the Windlass 4:, which is journaled in hangers 5, attached to the truck 6. To one of said hangers is secured a pawl 7, engaging a ratchet 8, journaled on the common shaft 9 of the windlass 4, a crank-handle 10 being secured to the end of said shaft. The said rope 3 passes through the ends of the hangers 2 and downwardly on the other side of the building, being attached to truck 11, having arranged thereon shafts 12, from which extends downwardly a rod 14, carrying a pointed end 15, the latter serving to firmly secure the truck 11 to the ground.

The reference-numeral 16 indicates a pulley and block carrying a hook 17, to which is secured a block and pulley 18, the latter being connected, by means'of the guide-rope 19, t0 the block and pulley 20, carrying the hook 21, serving as means to secure the wire cage 22.

It will be noted that when the apparatus has been adjusted to the proper height with the different stories of the building the wire cage may be easily shifted laterally from one window to the other, as indicated in dotted lines in Fig. l of the drawings, and that the same may then be readily lowered to the ground by means of the guide-rope, and in order to raise or lower the cage to the higher or lower stories of the building the Windlass is operated in the desired direction. The cage may then be shifted laterally along the line of the windows, as illustrated in the drawings. It will be seen that by this arrangement the cage may be easily shifted to any window of the building, and the occupants thereof may then be conveyed by the cage to the place of safety.

The many advantages afforded by the use of my improvedfire-escape will be readily apparent from the foregoing description, taken in connection with the accompanying drawings. I

Particular attention is directed to the fact that various changes may be made in the details of construction without departing from the general spirit of my invention.

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

In a fire-escape, the combination with the hangers, of a rope passing over said hangers, a movable truck having a shaft arranged thereon, a pointed rod carried by the shaft for engagement with the ground, one end of the rope being secured to the truck, a second movable truck, a Windlass secured thereto, a pawl and ratchet for controlling the movement of the Windlass, the other end of the rope being secured to the Windlass, a pulley engaging the rope between the hangers, a In testimony whereof I have hereunto block and pulley carried by the first-named signed my name in the presence of two sub- IO pulley, a guide-rope connected to the secondscribing witnesses.

named block and pulley, a third block and 5 pulley connected to the second-named block FREDERICK FRISHKORN' and pulley by means 01": said guide-rope, and In presence of a cage connected to the third-named block LOUIS MOESER, and pulley, substantially as described. M. HUNTER.
