JOSEPH HOTCIIKISS, OF BRIDGEPORT, CONNEC'IIOIIT, ASSIGNOR OF ONE-HALF TO THE (IOI LTER & MCKENZIE MACHINE COMPANY, OF SAME PLACE.

FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 394,272, dated December 11, 1888.

Application filed October 4, 1888.

T 0 all whom it may concern.-

Be it known that I, JOSEPH IIOTCHKISS, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Fire-El.- capes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has reference to certain new and useful improvements in. fire-escapes, but has especial reference to that class of such devices in which a portable carriage or has ket is adapted for instant use in ascending to or descending from the stories of a building, the latter bein provided with suitable means whereby said carriage or basket maybe secured, guided, and operated.

The object of my invention is to afford a simple, strong, and effective fire-escape and to render the latter adapted for instant use.

\Vith these ends in view my invention consists in the details of construction and combination of elements, such as will be hereinafter fully set forth, and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertains may fully understand the same, I will proceed to describe its construction and operation, referring by letter to the accompanyin g drawings, forming a part of this specification, and in which- Figure 1 is a front elevation showing my improvement adapted for use; Fig. 2, a side elevation of the same; Fig. 3, a plan view of the same, the pipe and one of the hangers being sectioned horizontally; and Fig. 4 a detail broken perspective illustrating particularly the adjustable shackle.

Similar letters denote like parts in the several figures.

A represents the outer wall of a building, to which is secured an iron pipe, B, by means of hangers (l, fastened within or to the wall, as may be desired. These hangers embrace the pipe and are flush with the surface thereof, so as to afford no obstruction to a free travel of the shackles, as will be presently set forth. The top hanger may or may not be flush with Serial No. 287,186, (No model.)

the pipe, and I have shown it as con stituting a shoulder around said pipe merely to afford a convenient stop to prevent the bracketfrom being drawn up too far.

Dis the bracket, the lower or brace arm whereof is provided at the end with an open shackle, E, conformed to the curvature of the pipe, while the upper or main arm has at its extremity a closed shackle made in two sections, F G, the former integral with said arm, while the latter is pivoted thereto, to operate after the manner of alatch, as shown at-Fig. I.

In applying the closed shackle to the pipe the section 1 is hooked around the latter, the.

section G closed, and the two sections secured in this position by a sliding collar, II. The lower shackle embraces the pipe only as a guide for the brace-arm to permit the latter to readily perform its function as a prop or support to the main arm,while the latter is adapted to be secured as against withdrawal from the pipe by means of the closed shackle. lVhen in proper position with respect to the pipe, the bracket may readily be swun around to cover as much area as possible.

I is a hood secured to the wall of the building immediately over the top of the pipe, and depending from this hood is any suitable pulley-block, .I, within which is journaled a pulley, K. At the base of the building is a box, Ii, within which is a pulley, \I, journaled in suitable bearings, N, an opening, 0, being formed in said pipe opposite to this pulley. The foot P of the pipe is planted in the ground, or in a cement-bed, as may be desired. A rope, Q, of wire or other non-combustible material, is run through the pipe over and under the pulleys K M, respectively, the rope being brought down outside the pipe and weighted, as with a ball, R, in order to readily bring said rope by gravity in a position easy of access at the bottom of the pipe.

To the bracket D is secured any ordinary basket or receptacle, S. The upper end of the rope is provided with a hook, T, which is inserted through an eye, U, in the collar 11 when the bracket is applied for use. The bracket being in proper operative position, as shown at Figs. 1 and 2, the raising and lowering of the same is effected by hauling and slackening the lower end of the rope. hen

not in use, the lower end ofthe rope may be pulled down and secured around any suitable cleat (not shown) Within the box L and locked therein as an insurance against tampering. A rope, V, may be fastened to the outer end of the bracket for the purpose of swinging" the latter into position for service. The bracket and its attached basket are intended as a part of the firemens regular outfit and apparatus, so that the general appearance of the building is not defaced or rendered unsightly by any local apparatus, the pipe presenting an effect not unlike that of a small drain-pipe. The hood at the top of the pipe affords a protection as against the clogging of the pipe by dirt or other obstacles.

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

1. The bracket having at the end of its main arm an adjustable closed shackle and at the end of the brace-arm an open shackle, substantially as set forth.

2. The hook formed integral with the main arm of the bracket, in combination with the latch pivoted to said arm, and the collar adapted to embrace said arm and latch,whereby a closed shackle is formed, substantially as shown and described.

3. The combination of the pipe open at the top and bottom, the pulleys journaled opposite to said openings, the rope through said pipe run over the top pulley and under the bottom pulley, the bracket having a hook formed on the end of its main arm conformed to the general shape of the pipe in cross-section, a latch pivoted to said arm, a collar adapted to encircle said arm and latch, and an open shackle formed on the end of the brace-arm of the bracket, substantially as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

JOSEPH HOTOHKISS.
