FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 384,143, dated June 5, 1888.

Application filed August 23, 1887. Serial No. 247,653. (No model.)

To aZZ whom, it may concern.-

Be it known that I, STEPHEN HALSEY GARDI- NER, of Lynn, in the county of Essex, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Fire- Escapes and I do hereby declare the same to be described in the following specification, and represented in the accompanying drawings, of Which Figure 1 is a front elevation, and Fig. 2 a longitudinal and median section, of a fire-escape of my invention, the nature of which is defined in the claim hereinafter presented.

The said fire-escape consists, mainly, of two series of metallic disks, A, chains B, connecting the disks of each series, and a series of metallic rods or rounds, 0, extending from one to the other series of disks, each rod connecting two disks near their centers, in which case the rod is eccentric to each disk. The disks of each series are disposed at equal distances apart, each being joined to that next to it, whether above or below it, bya short chain, B. Extending from each of the two upper disks is one of two chains, D, such chains being provided at their upper ends with hooks a to admit of their being hooked into staples fixed in the window-frame or other suitable part of a building. There also extends from the two lower disks a looped chain, E, whose ends are 0 joined to the disks.

When the fireescape so made is suspended from a window of a building, the disks, by

contact with the front of the said building,

keep the rounds at a distance therefrom to en- 5 able a person to easily ascend or descend the fire-escape. The looped chain is of advantage in supporting the fire-escape at an inclination to the building by means of a crowbar or stake driven through the loops of the chain and into 0 the ground. Such looped chain is also useful for other purposes.

The above fi re-escape becomes aladder which can be easily folded into little space for storage or otherwise.

I claim- A fire-escape consisting of the combination of disks A, connected by chains B, rods or rounds 0, extending from a disk on one side to a disk on the other and secured eccentrically 50 to said disks, withthe two upper chains, D, and the bottom looped chain, E, as set forth.

, STEPHEN HALSEY GARDINER.
