Fl RE-ESCAPE.
SPECIFICATION forming part of Letters Patent No. 707,346, dated August 19, 1902.
Application filed March 26,1902. Serial No. 99,963. (No model.)
To (ZZZ whom it may concern:
Be it known that 1, DAVID NEALE, of the city of Fort Calhoun, Washington county, State of Nebraska, have invented certain new and useful Improvements in Fire-Escapes, of which the following is a full, clear, and, exact description,reference being had to the accompanying drawings, forming a part hereof.
My invention relates to fire-escapes; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.
My object is to produce an improved fireescape; and my invention consists of a suitable frame, a carrying-shaft mounted in the frame, a carrying-rope attached to the carrying-shaft and adapted to be wound thereon, a carrying-shaft speed-governor attached to the carrying-shaft, a brake connected to the carrying-shaft, a brake-rope connected to the brake, a carrying-frame attached to the opposite end of the carrying-rope from the carrying-shaft,a brake-shaft mounted in said carrying-frame, said brake-rope being attached to and wound upon said brake-shaft,and a brakerope speed-governor upon said brake-shaft.
Figure 1 is a view illustrating the operation of my improved fire-escape, parts being broken away to economize space, other parts being broken away to show the construction. Fig. 2 is a top plan View of the frame in which the carrying-shaft is mounted, parts being broken away to illustrate the construction. Fig. 3 is an enlarged detail of the brake-controlling mechanism.
Referring to the drawings in detail, the frame, comprising the end pieces 4 and the casing 5, is mounted upon the base 6, and a door 7 provides access to the end of the case in which the governor operates, and a slot 8 provides access through the casing to the end of the shaft upon which the carrying-rope is wound. The carrying-shaft 9 is mounted in the frame, and the carrying-rope 10 is passed through the slot 8 and attached to the shaft and adapted to be wound thereon.
The carrying-shaft speed-governor com prises the four pairs of arms 11, fixed to the shaft 9 and extending radially therefrom, and the centrifugal weights l2, slidingly mounted upon said arms, the outer ones of said weights being curved to fit the inner face of the casing 5.
A crank 13 serves as a means of operating the shaft 9 to wind up the rope 10. The brake-wheel14 is fixed upon the opposite end of the shaft from the crank, and the brakeband 15 is attached to the pin 16, extending from the frame, and extends around the wheel and over'the pin 17, and the brakerope 18 is attached to the free end of the brake-band.
The carrying-rope 10 extends upwardly over the pulley 19 and then outwardly and downwardly through the window 20, and the carrying-frame 21 is attached to the lower end of said rope, said carrying-frame having stirrups 22 at its lower end and a strap 23 to encircle the body under the arms.
The brake-shaft frame 24 is fixed upon the upper end of the carrying-frame 21. The brake-shaft 25 is mounted in said frame, said brake-rope 18 being attached to and wound upon said shaft, said rope passing over the pulley 26, mounted upon the window-sill. The brake-rope speed-governor 27 is mounted upon one end of the shaft 25 and is identical in construction with the carrying-shaft speedgovernor.
In practical operation when a person is in danger of fire the carrying-frame 21 is attached to the body by placing the feet in the stirrups 22 and placing the strap 23 around under the arms, and then the person will climb out of the window, and when the person lets go of the window-sill the carryingrope 10 will sustain the weight and lower the person to the ground, the speed'of the descent being retarded by the centrifugal force of the weights 12 against the inner face of the casing 5 and by the strain of the brake-rope 18 upon the brake-band 15 against the brakewheel 14. The strain of the brake-rope 18 will be regulated by the brakerope speedgovernor 27, and if this is not sufficient the person may manually engage the rope 18, and, if desired, the descent may be stopped at any point by pulling the rope 18 to set the brake.
I claim 1. A fire escape comprising a suitable frame; a carrying-shaft mounted in the frame;
a carrying rope attached to the carryingshaft and adapted to be wound thereon; a carrying-shaft speed-governor attached to the carrying shaft; a brake connected to the shaft; a brake-rope connected to the brake; a carrying-frame attached to the opposite end of the carrying-rope from the carrying-shaft; a brake-shaft mounted in said carrying-frame, said brake-rope being attached to and wound upon said brake-shaft; and a brake-rope speed-governor upon said brake-shaft, substantially as specified.
2. In a fire-escape, the base 6; the casing 5 mounted upon the base; the end pieces 4 closing the casing; the door 7 providing access to one end of the casing; the slot 8 providing access to the other end of the casing; the carrying-shaft 9 mounted in the hearings in the end pieces 4:; the carrying-rope 1O wound upon the shaft and passing outwardly through the slot 8; the arms 11 extending radially from the shaft 9; the centrifugal Weights 12 slidingly mounted upon said arms to engage the inner face of the casing; the brake-wheel 1 fixed upon the shaft 9; the brake-band 15 engaging the brake-wheel; the brake-rope 18 attached to the brake-band; the carrying-frame 21 attached to the lower end of the carrying-rope; a brake-shaft mounted in the carrying-frame upon which I the brake-rope is wound; and a governor controlling the brake shaft, substantially as specified.
In testimony whereof I affix my signature in presence of two witnesses. 7
DAVID NEALE.
