FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 254,413, dated February 28, 1882.

- Application filed January 4, 1882. (No model.) i

To all whom it may concern:

Be it known that I, THOMAS J. VINTON, a citizen of the United States, residing at Holly, in the county of'Oakland and State of Michigan, have invented certain new and useful Improvements in Fire-Escapes, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improvement in fire-escapes; and it consists in the peculiar combination and arrangement of parts, as will be more'fully set forth herein after, whereby an efficient fire-escape is produced.

Figure 1 is a side elevation of my invention. Fig. 2 is a top plan view of the same. Fig. 3

'is a detail view of the stirrup. Fig. 4 is a detail view of the brake-rod which operates on the Windlass.

A is a truck which forms the base for the machine, and is provided with the wheelsaand the handle B. The handle B is fitted into grooves made in the side of the box forming the truck, so as to be readily drawn out when required, as shownin dotted lines, Fig. 1. The truck is hollow, and is provided with the removable lid or cover a, whereby access may be gained to its interior, andis designed to hold the chains, ropes, &c.,used in the operating of the escape. The truck is further provided with the hand-railsb on each side, as shown.

0 is a removably-attached supporting-rod, which extends up through the front end of the truck. Upon this rod is pivoted the crane, which is composed of the vertical beam (1, the horizontal beams d 61* d and the angular brace d. The beam d is slotted at d ,-and in this slot are pivoted the large pulley E and the small pulleys e e.

Mounted upon the same shaft with the pulley e is the curved arm F, to the lower end of which is secured the pulley f, its upper end being bent outward and flattened, so as to form a brake, f, bearing upon the upper portion of the periphery of the pulley E.

Pivoted in the brace 01 is the brake G, which bears against the lower portion of the periphery of the pulley E, and has the handle 9 extending back over the truck A.

Upon the horizontal beam cl is mounted the drum H, which is provided with the crank h,

and is controlled by the brakerod h, pivoted I to the vertical beam (I, the bifurcated ends of which are adapted to be let down onto't'he drum and hook into the chain to prevent it from unwinding.

Pivotecl upon the upperend of the rod 0, and extending at right angles to the crane, normally, is the beam I, one end o hich is longer than the other, and is adapted to extend across the window to prevent the escape from tilting forward when in use.

The crane is braced, when in use, by means of the rods K, which are pivoted to the beam d at k, and have theirlower bent endspassed through the staples k with which the truck is provided. These rods aterendered perfec' 1y secure in this position by means of the transverse rods 1 l.

To the lower side of the outer end of the beam (1 is secured the caster 0, which is used when rolling the fire escape about in transportation. From the rear end of the truck projects the lugs N, between which is pivoted the stay-bar n, the lower end of which is bent and sharpened to apoint and intended to be driven into the floor when the machine is placed in position against a window, as shown in Fig. 1, the window being indicated in section in dotted lines.

D is an endless chain, which is wound upon the drum H, and passes over the pulleyf, down to the ground, then up over the pulley 0, down under the pulley E, over the pulley e, to the drum.

By means of this construction of parts the machine can be readily taken to pieces and transported, and as readily put in order for operation again.

1 is a stirrup, which is attached to the chain D at any point desired by means of the hook 2, Fig. 3. Two of these stirrups are used for each person, one on each foot.

In practice my invention is intended to be placed in the top story of the building, so that the chain will extend down in front of the windows on the lower floors. By means of the brake G the rapidity of the descent of the the stirrups can be drawn up by turning the crank it, in readiness for others.

Having thus described my invention, I claim 1. The truck A, provided with the sliding handles B, fitted in grooves in the truck, and the pivoted stay-bar n, in combination with the operating hoisting apparatus, substantially as shown.

2. The rod 0, removably attached to the truck A, in combination with the transverse beam 1 and the crane d d d (1 substantially as described.

3. The combination of the crane consisting of the vertical beam (2, horizontal beams d d d, and angular brace 61, with the pulleys e E e, pivoted arm F,itsbrakef and pulleyflthe drum-crank h, and brake G, all arranged to operatesubstantially as shown and described.

4. The combination of the crane consisting of the vertical beam (1, the horizontal beams d d d, and brace d, and provided with pulleys e E 6, vertical arm F, brake f, and pulley f, and drum H, crank h, brake-rod h, and brake G, with the rod (J, transverse beam I, and truck A, all arranged to operate substantially as shown and described.

5. The crane provided with the braces consisting of the rods K, pivoted thereto at their upper ends, and having their lower ends removably secured to the truck A, the rods K being held in position by the transverse bars I l, in combination with the supporting-rod C and truck A, substantially as described.

6. The combination of the truck A, having the removable lid a, the sliding handles B, and the pivoted stay-barn, the supporting-rod 0, upon which is pivoted the transverse beam I, and crane consisting of the vertical beam (1, the horizontal beams d 61 d the said horizon- .tal beam d being provided with the pulleys e E e, the pivoted arm F, being formed into a brake, f, at its upper end bearing against the pulley E, and having the pulleyfat its lower end, the brace d, having pivoted thereto the brake G, bearing against the under side of the pulley E, and provided with the handle 9, the beam 01 having mounted thereon the drum provided with the endless chain D, and the crank h, the chain being provided with suitable detachable stirrups, 1, the crane being braced in proper position by means of the rods K, pivoted thereto at their upper ends, and having their lower ends removably attached to the truck A, and heldin position by means of the transverse bars l Z, all being combined to operate substantially as shown and described.

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

THOMAS J. VINTON.
