' *detached from the main rope the opening 15 fis. closed by means of a leaf spring 16 which Toall whom fit may concern: Y

v j 1 vBe it known that I, GARLAND Y. THOMP- son, a citizen of the United States, residing l. at 'Rossmoyna in the county of Hamilton i' "and `State of Ohio, have invented new and useful mprovements in Fire Escapes, of which the following is a specification.

invention relates to lire escapes, and Vits primary object 1s to provide a device of this character which 1s simple, durable and 'VVth 'the' above and other obl@CtS in View `the invention consists in the construction, 'combinationand arrangement of parts here- -inafter fully'described, claimed and illustrated i'n the accompanying drawing, whereln:

Figure 1 is a perspective view of a fire escape`constructed 1n accordance with my Y nal sectional view of the rope brake.

Referring to the drawing by reference numerals, 1 designates they main rope, 2 the rope brake, 3 the supporting rope and 4 the l brake controlling rope of my improved fire escape.-

vkThe rope brake comprises a body 5, which f is curved longitudinally and which' is pro'- *aoY videdat vits relativelyV lower end with a recess 6. A roller 7 1s journaled in the recess 6 and the side walls of the recess are pro- 'vided with perforations 8.

' jaw 10.

`shaped Vin cross-section, the longitudinal Y At a point adjacent its relatively upper end the body is provided with a slot 9 and angularly projectingv from itsV relatively upper end is a The jaw 10 is substantially U- y'edges of the flanges 11 thereof being cut away, as at 12. A pair of relatively spaced 9j. cylindrical members 13 are mounted upon f bolts 14 secured to the side flanges 11 of the j'aw10- In practice, the main rope 1 Vpasses through the slot 9, and to permit the rope 45 brake to Ybe Vreadily and quickly applied to and removed from the main rope, one side wall of the slot 9-is provided with an open- *ing 15 through which the rope may be readily and quickly inserted into the slot.

Toy prevent'the rope brake from becoming is secured in applied position by means of a rivet, not shown. A'lever 18 is pivotally mounted at a point between its ends in the .l Islot 9 by means of a bolt 19. The lever is Specification of Letters Patent.

curved longitudinally and is provided with a plurality of perforations through the medium of which the supporting rope 3 may be secured to the lever at different points. Projecting forwardly from the relatively upper Aend of the lever 18, is a jaw 21 which is recessed, as at 22. A cylindrical member l 23 is located in the recess 22 and it is mounted upon a bolt secured to the side walls of seid recess. Then the jaws are moved into closed or active positions, the member 23 occupies a posit-ion between the members 13, thereby frictionally clamping the main rope, the cut away portions 12 of the flanges 11 permitting the member 23 to be moved inwardly beyond the planes of the members 13.

The brake controlling rope is secured to the body 5 by having one of its ends passed through the perforations 8 and then secured to the rope in any suitable manner, and the controlling rope is secured to the supporting rope by means of a rope section 26. Y

In practice, the main rope 1 is suspended at a suitable point outside of the building, the rope brake applied to the main rope, and the supporting rope passed about the person at a point beneath the arms, the supporting rope being secured about the person by means of a snap hook 25. As the supporting rope 3 is secured to the relatively lower end of the lever 18 and passes over the roller 7, the weight of the person will move the aws into closed or active positions, thus causing them to frictionally engage the main rope. This frictional engagement of the main rope is so great that the person is suspended thereon.

TWhen it is desired to descend all that is necessary is to pull downwardly on the brake controlling rope il, as thereby the jaws are moved in opposite directions away from the main rope. It should be apparent that the person can readily and quickly control the speed of his descent. As the supporting rope can be secured. to the lever 18 at different points, it should be apparent that the frictional engagement of the main rope by the jaws can be regulated. The rope section 26 limits the opening movements of the jaws.

From the foregoing description taken in connection with the accompanying drawing, the construction and mode of operation of the invention should be understood without a further extended description. j

Changes in the form, proportions and minor details of construction may be made within the scope of the claims without departing from the spirit or sacrificing any ot tbe advantages oit the invention.

Having'fully described and illustrated my invention, what I claim is:

l. A tire escape including a. rope brake consisting of a body provided with a slot, one oi the side walls of said slot being provided 'with an opening, a leaf spring` secured to the side wall and adapted to close the opening'. a pair of relatively spaced members mounted on the jaw, a lever pivotally mounted at u point between its ends in the slot of the body, and a member mounted on the lever. y

A lire escape including a rope brake consisting of a body provided with a recess at one end and with a jaw at its other end,

said body being` provided with a slot having one of its side Walls provided With an open ing7 a leaf spring Secured to said side Wall and adapted to close the opening, a pair of relatively spaced members mounted to the jaw of the body, a'lever provided with a jaw at. one end and with a plurality of spaced openings, said lever being pivotally mounted at a point between its ends in the slot of the body, and a member mounted on the jaw ot the lever.

In testimony whereof I atix my signature in presence ot' two witnesses.
