FIRE ESCAPE CHUTE MOUNTING Filed Jul 14, 1943 INVENTOR.

HAELAND D- ELWOOD H/S ATTOEN Patented May s, 1945 UNITED STATES. PATENT OFFICE FIRE ESCAPE CHUTE MOUNTING Harland D. Elwood, Detroit, Mich., asslgnor of one-half to Lewis A. Eastman, Wyandotte,

Mich.

Application Ju1 '14, 1943, Serial No. 494,667

. 4 Claims.

This invention relates to fire escape apparatus and particularly t terminal supporting frames and mountings for flexible chutes, such as disclosed in Patent 2,297,544, dated Sept. 29, 1942.

An object of the invention is the provision of a device of the character referred to, which can be stored and transported, together with the chute, in a fiat condition and in a compact space.

Another objectof the invention is the provision of a device which can readily be carried in a small space on a fire department vehicle, and

can be used in localities where vertical distances to be reached do not exceed forty feet.

Another object of the invention is the provision of a device having pivoted wings for supporting the flexible chute, which wingsextend beyond the walls of the building, and can be rotated, 50 a vantages of the invention will become more apparent as the description proceeds, reference being made from time to time. to the accompanying drawing in which: I

Fig. l is a rear elevation of a device embodying my invention, in position on the inside of a window frame.

Fig, 2 is a side elevation of the device illustrated in Fig. 1.

Fig. 3 is an enlarged frag entarydetail illustrating the manner in which the chute support-, ing bar is mounted.

Fig. 4 is a perspective view of the frame with the flexible chute detached Referring now more particularly to the drawing, it will be understood that in the embodiment herein disclosed, the device consists of a. pair of rectangular members 6, which aremounted to the cross member 1. The rectangular members 6 are preferably made of sections of hollow steel tubing joined by means of welding and finished in any suitable manner. Pivoted as at 8, to the inside vertical strut-9, of the rectangular members 6, are rotatable wings H), which are preferably made of a single length of steel tubing bent to the conformation shown in Fig. 4. Wings 10 are provided with chute supporting members ll, l2, and l3. A removable bar I4, is mounted above the cross-member 'l, between the struts 9, of the The foregoing and other objects and adterminal rectangular members 6, and is held at either end in .U-shaped brackets 15, which are welded to the cross-bar I and the vertical strut 9. A bolt It prevents the bar M from being dislodged from the U shaped bracket [5. The rectangular members 6 are provided with rings H, to which a carrying strap may be attached.

The chute I8 is provided with an extension member l9, which in turn is formed with a loop 20, which is adapted to engage the removable bar M. The sides of the chute l8 are secured, by any suitable means, tojthe members ll, I2, and I3 carried on the rotatable wings ID. The chute I8 is preferably left attached to the terminal frame at all times. 1 However, it can be carried separately and attached to the frame prior to use. When the frame andthe chute are carried in assembled condition, the wings in of the device lie flat against the rectangular members 6, and the chute in folded condition is held closely along-side the device. When an operator arrives at the scene of a fire, the chute is unfolded and the terminal frame, together with one end of the chute is carried up a ladder and inserted through an open window of the building to the inside. The rectangular members 8 are then placed in position on the inside of the windowlframe and serve as abutment membersto distribute the stresses and strains over a wide area. One or two men on the ground then hold. the free end of the chute and the device is ready I for use..

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

1. In a device of the character described the combination of a pair of rectangular abutment members connected by a tie rod, said abutment members being adapted to contact the inside walls of a building on either side of'a window opening each of said abutment members having a wing pivoted to one of its vertical struts, said wings being arranged to extend through. said window opening.

2. The combination defined in claim 1', including a removable bar positioned between the abutment members and parallel to said tie rod.

3. The combination defined in claim 1, in which the said wings are provided with means to support a flexible chute.

4. In a device of the'character described the combinationof a pair of rectangular abutment wings being shaped in the form of a trapezium, a

removable barfmounted between said abutment members, and means on said wings, adapted to cooperate with said removable barto support a flexible chute.
