Application filed. some 11, 192i. s ri a nofaoiooofl 1 T ciZZ ioliom it. cohcem I Be it known that I,- Gnon n AL im- Roenn'rs, a citizen. of the United States, residing atPaducah, in the countyofMcCracken and State of Kentucky, have invented new and useful Improvements in Fire Escapes, of which thejfollowing is a specification;

This invention relates to; improvements in-fire escapes. I

An object of the simple and inexpensive device embodying novel features of construction; whereby any number of persons may conveniently escape with perfect safety from a window of a burning building.

Another object is to provide a light and durable device which may be folded to one side of a window casing when not in use and can be quickly adjusted at a moments notice to enable the occupants of a room to escape. 7

Another object is to provide a strong and efficient device which will support a rope or cable at a safe distance from the wall of the building and prevent any injury to a person while descending to the ground.

With the above and other objects and advantages in view the invention consists in the novel construction, combination and arrangement of parts described and claimed.

In the drawings forming part of this application like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a side elevation of the invention in open position and secured to a window casing of a building.

Figure 2 is a side elevation of the invention in folded position and secured to the wall of a building.

Figure 3 is a top plan view of the invention in open positio Figure 4 is a detail perspective view of the U-shaped supporting member.

Figure 5 is a detail perspective view of the vertical post.

Figure 6 is a. detail brace rod.

Referring now particularly to the drawings, the numeral 10 indicates a pair of spaced metallic brackets which are removably secured to one side of a window casing 11 and are provided with aligned openings 12. A metallic post 13 is provided with a transverse opening 15 adjacent to perspective view of the invention is to provide a' the supporting member.

' The brace rod 22 is provided with a trans- A verse opening 23 adjacent to its upper rounded end which receives a bolt 24: extend ing through aligned transverse openings 25 which are "formed in the par allel arms of a U-shaped metallic supporting member 26.

A bolt 27 extends through a pair of aligned transverse openings 28 at the inner end of A pair-of spaced lugs 30 project upwardly arms of the supporting member and are from the parallel" adapted to engage a window sash'. 31 when the U-shaped member is sition. V I p A rope or cable32 is secured to a metallic moved to open polink 33 which is supported upon a bolt- 34,

extending through verse openings 35 at the outer end of the. Supporting member. A plurality of spaced 3, pair of aligned tran sballs 36 are securedfirmly to "the rope 32 a and serve as gripping elements to enable the escaping person to let himself down gradually to the ground.

A knob 37' is removably secured to the. outer end of the supporting member and serves as a handle to facilitate the quick adjustment of the device. I 1

An L-shaped hook 38 is removably secured to one side of the supporting member and retains the rope in coiled position when the device is not in use.

When the device is not being used, the I bolt 27 is disengaged from the, opening 15 in the post by means of theknob 37 whereupon the inner end of the supporting member moves downwardly'to assume the folded position illustrated in Figure 2. The rope 1 is coiled and placed upon the hook 38. However, when the device is to be used the win dow sash is raised and the rope is dropped out of the window. The knob 37 is then moved outwardly, thus raising the inner endv of the supporting member until the bolt 27 engages the opening 15. The window sash is then pulled down :between the lngs 30- so as to retain the device in position.

While it is believed that from the foregoing description and: astndy ot the=-draw-- ings that the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein-shownanddescribed and that such. changes may be resorted to when desiredas; fall within thescope of what-is claimed."
