FlRE ESCAPE.

SPECIFTCATION forming part of Letters Patent No. 285,808, dated October 2, 1883.

\ Application filed March 14; 1883. (No'modeh) To all whom it may concern:

Be it known that we, DAVID GALIVAN and JOHN C. MANNING, citizens of the United States of America, residing at Buffalo, in the county ofErie and State of New York, have invented certain newand useful Improvements in Fire- Eseapes, of which the following is a specification, reference being had therein to the'accompanying drawings.

This invention relates to afire-eseape having a safety-ear working vertically in frames attached to and suspended from a hanging truck running on double tracks arranged just under the cornice of a high building, with an extra rail lower down on the side or front of the building, and standing out therefrom, on which guide-wheels attached to the back of the frame run to steady the whole device. On the rails the device is moved to any part of the outside of the building or block.

The invention consists in its construction.

The obj ect of this invention is to have a permanent device, in connection with the outside of a block or building having a safety-car as a part thereof, which can by simple devices be run up and down from or to any window in any story of the building, by which old or young persons and women and children can escape without danger and valuable property be lowered to the ground, all as fully hereinafter explainc d.

In the drawings, Figure 1 is an elevation of part of a building with a front view of our device in position thereon. Fig. 2 is a side elevation of the upper part of the fire-escape, showing the truck and the safety-car, &c., drawn up. Fig. 3 is a cross-section of the car enlarged, showing the friction-wheels and cable in connection therewith; Fig. 4, an enlarged side elevation of the lower part of the escape, with the brake device for preventing the too quick descent of the safety-car. V

A represents a track attached to the upper part of a building, just under the cornice B, as shown. This track consists of two rails at a little distance apart, and on these a truck, 0, runs. The truck consist-s of a frame with four wheels, the front ones, a a, made double, the front part, a, being a grooved pulley and the back part, a, made smaller, and also grooved torun on the first track, A. The back wheels,

I), run on the second track,but are not grooved. This double track is to give greater steadiness tothe whole device.

\Ve are aware that asingletrack and a hang ing ladder running on said track have been i made.

Attached to the bottom of the truck, and depending therefrom, are two side frames, D D, made preferably of T-iron, (see Fig. 4,) and coming nearly to the ground, and which will have suitable strengthening and bracing rods.

Another track, A, is arranged on the building, above the lower story. It is a single track, and two grooved wheels, 0 0, (see Fig. 4,) run in connection therewith to aid in steadying the device. The wheels 0 c are on a frame projecting from the back of frames D.

F is a safety-car, made light but strong, of iron, running between the side frames, D D, as in Fig. l, and kept from swaying by friction-wheels d (1, two on each side of the car, and which run on the T side pieces, D D.

" The car is raised and lowered as iollows: A wire or chain cable, 0, is attached to the top of car F. This runs up and over a pulley, f, at the top of the frames and below the truck 0. The cable then passes down to near the bottom of the escape and over a grooved pulley, g, and back up to the bottom of the car, making an endless cable. 011 the side of the pulley g is a toothed or gear wheel, h, which meshes into a toothed wheel, i, below it on a separate shaft, and is worked by a crank, j. (See Fig. 1.) This raises and lowers the car from the ground; or it may be operated from the car, as follows: Three friction-wheels, 1 2 3, are set in front of the car and the eablee run partly around them, as shown in Fig. 3. To wheel 1 is connected, by suitable gears, a crank, 70, inside the car. This is in case there is no one at the lower crank, j, so that the car may be run by those in it, and the frictionwheels prevent a too quick running of the car when loaded. To further aid this there is a counter-weight, 1, running down one side of frame D,which is connected to the car by a cable, an, running over pulley or pulleys n at the top of frame D. In addition to these, we have a safety stop or brake, as follows: On same shaft as pulley g and gear-wheel h,which operate the car-cable c, is a friction-wheel, p.

Above and back of this is a rod, q, running through the frames D loosely, on which is a brake, 0-, which presses on the brake-wheel p by means of a connectingarm, s, on the end of the rod q. Said arm 5 is operated by a long rod, 2, the lower end pivoted to arm 8 and the upper end to one arm, it, of atriangnlar-shaped cam, G, pivoted to the side of frame D, is shown. The other arm, a, of the cam projects outward and operates in connection with a swinging weighted stop, w, attached or pivoted to the lower corner of the car F, as shown in Fig. 1, which, when the car descends, will strike the projecting arm a, which raises the arm 8 and 1 us on the brake r to the wheel 2, thus deadenin gthe motion ofthe whole cable e. A spring-bar, y, behind the cam G keeps the brake on until thrown off by hand from below by the spring-rod 2, which is pivoted to the arm 8, as shown in Fig. 4. This prevents the car, when overweighted, from coming down too fast, to the injury of the passengers.

The whole fire-escape is moved forward or back on the tracks A A A by an endless cable, 0, running over the truckmlleys (I- a and down to the bottom of the device and around the pulley or wheel H, which is operated by a crankhandle, I.

In Fig. 2 is shown the side of aladder, J, attached to the front of car F, and curving out and up, so as to cfetr the cornice and take people from the roof into the car or from the car to the roof. As will be seen, the car can be raised and lowered either from the ground or car, stopped at any story of a building,and quickly run down and back to any point desired. It being all of metal, it cannot burn or be destroyed until the building is. It is intended to be on a building, or on a block, all the time, and the lower parts will be boxed up in hinged boardsthat can instantly be swung open when desired It will be found oi. great value for firemen especially those with a chemical engine, to carry them up by the car,with hose and pipe, to the story or window or roof, where by quick work an. extensive fire and great loss may be prevented.

Ve claini- I 1. In combination with the three permanent rails A A A, suitably arranged on a block or building, the truck (5 a a I), with the attached side pieces or frames, D D, dependent therefrom, the safety-ear F, running up and down therein, operated by the endless cable 0, )u ll eys f 1 gear-wheels 7t 1 cranksj, the whole moved on the tracks A A by thepulleys (1.0, H, end less cable 0, and crank I, all combined, arranged, an d operating substantially in the 11 ran ner and for the purpose specified.

2. In a fire-escape, in combination with the safety-car F and frames D D, the weighted swinging stop 10, attached to the car, the brakewheel 1), brake r on arm q, the arm 8, rod 1, triangular pivoted cam G u a and stop and spring-rod 2, all arranged and operating substantially as and for the purpose specified.

3. In a fire-escape, the safety-car F and frames D D and endless cable 0, in combination with the side friction-wheels, (M, the front friction-wheels, 1. 2 3, in connection with suitable gearwvlieels, and crank it, inside the car, all arranged substantially as and for the purpose specified.

In. testimony whereof we affi x our signatures, in presence ol. two witnesses, this 22d day of February, 1883.

DAVID GALIVAN. JOHN C. MANNING.
