FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 547,450, dated October 8, 1895.

Application filed April 15, 1895.

To all whom it may concern.- 7

Be it known that I, FRANCIS M. QUINN, a citizen of the United States, residing at Astoria, in the county of Clatsop and State of Oregon,have invented a new and useful Fire- 1lslscape, of which the following is a specificaion.

This invention relates to an improvement in fireescapes.

The object of the present invention is to provide a simple and inexpensive form and construction of portable fire-escape, which is adapted to be attached to and carried upon the person, which will be capable of rapid and easy manipulation, which will be efficient and safe in practice, and which will possess other advantages which will appear in the subjoined description.

To this end the invention consists in certain features and details of construction and arrangement of parts, as hereinafter fully described, illustrated in the drawings, and

pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of the complete fire-escape apparatus, showing the supporting-belt, by means of which the different parts of the apparatus are carried upon the person. Fig. 2 is an enlarged detail perspective view of the hand grasp or rod, the brake-lever, and the spring-actuated wrist cuff or collar for supporting the hand of the operator. Fig. 3 is a horizontal section through the hand-rod, showing the hinged wrist-cuffs closed. Fig. .4. is a similar view with the parts shown open. Fig. 5 is a-detail perspective view of the grappleiron in operative condition. Fig. 6 is a simi lar view of the grapple-iron with the fiukes thereof thrown inward for transportation. Fig. 7 is a detail View of the single hook, showing also the wire and eyepiece carried thereby. Fig. 8 illustrates the manner in which the improved apparatus is utilized in practice.

, Similar numerals of reference indicate corresponding parts in the several figures of the drawings.

Referring to the drawings, 1 designates a suitable stout leather belt provided with the usual buckle and perforations, by means of which the same may be secured around the waist of the wearer. 'To the outer face of Serial No. 545,767. (No model.)

this belt, preferably at a point adjacent to the right hip of the wearer, is secured a metal sheath 2, of any suitable size and shape, for the reception of the grapple-iron and single hook to be hereinafter described. The object of the metal sheath is to cover the pointed flukes of the grapple-iron and the single hook to prevent injury to the hands or person of the wearer while the apparatus is being carried from place to place. The belt 1 is also provided in front with a metallic bracket or spool-holder 3, which may be secured thereto in any usual or preferred manner, in which is pivotally mounted a spool 4, having wound thereon a piece of soft wire 5 of any desired length, preferably of sufficient length to reach to the top of a five or six storybuilding, though the wire may be made longer or shorter, as desired. The belt is further provided at the back with a loop or pocket 6 for the reception of the wire-gripping device, which may thus be located in a position where it will be out of the way and not interfere with the work of the fireman or other party upon whose person the apparatus is carried.

To the end of the wire 5, contained on the spool 4, is attached a grapple 7, which is preferably made from heavy spring-wire and composed of three similar sections, each provided at its lower end with a pointed hook or fluke 8, extending outwardly from the main body of the grapple. These three sections are preferably formed with long shanks 9, which are connected only at one end, where they are provided with an eye 10, by means of which the grapple as a whole is secured to the end of the Wire or cable 5. The lower hooked ends of the grapple-section are left free or independent for the purpose of adapting them to be folded or forced inward, as indicated in Fig. 6, for adapting the grapple to be inserted into the sheath 2.

11 indicates an ordinary single hook, of any desired size and shape, provided at one end with an eye or loop 12, from which apiece of wire about three or four feet long extends to and is connected with aloop or eye 13, through which passes the main wire 5. y

The wire-gripping device, which will now be described, is placed upon the wire, 5 between the eye 13 and the spool around which said wire is wound. The gripping devicecon- ICC sists of a stout metal rod 14, to which is secured at suitable intervals several guidingeyes 15, through which the wire 5 is passed. Upon the lower end of the rod 14 are pivoted two similar and substantially-semicircular cuff-sections 16, which are adapted when closed to snugly embrace the wrist of the operator and to support his hand for a purpose that will appear. The cuff-sections 16 may be made of metal and internally lined or entirely covered with leather for protecting the wrist of the wearer. The cuff-sections are provided upon their outer faces. adjacent to their hinge with outwardly-extending horizontal flanges 17, and said flanges are beveled off or inclined at 18, and also notched, as indicated at- 19, adapting them to be acted upon by a spring-actuated latch 20 on one end of a spring-arm 21, secured at its opposite end to the rod 14. When the cuff-sections are thrown open, asin dicated in Fig. 4, the springactuatedla-tch 20 will engage the notches 19 grip-lever 22, slotted at its upper end, as indicated at 23, to stride the rod 14, to which it is pivoted, as shown. Beyond or above its pivotal connection with the rod 14 the griplever is provided with a shoe 24, which operates in connection with a flat surface or fixed jaw 25 at the upper end of the rod 14 to grip the wire 5 after it has passed through a perforation in the upper hooked extremity 26 of the rod 14.

In operation, the complete apparatus being strapped around the waist and supported in place by means of the belt 1 the operator takes the three-fluked grapple from the sheath and, drawing out a sufficient length of wire from the spool fastened to the front of the belt, he steps upon the sill of the window or door of the room in which he is confined and throws said grapple through an adjacent window, after which, by drawing carefully and slowly upon the wire 5, the grapple is caused to engage the sill or framework of the window through which it is thrown. The operator now engages the single hook 11 with the sill of the window or door in which he stands, and then, securing the cuff at the lower end of the rod 14 of the gripping device securely around his wrist and gripping the wire 5 by means of the gripping-lever 22, he lowers himself from the window, when, by the aid of said gripping device, he is enabled to lower himself at any desired speed to the ground, the wire 5 unwinding from the spool at the front of the belt during the descent.
