When the device is to be used, theca'sing drawn, and said container'may be removed from the reel of rope, or may be thrown out of the windowbodily with said reel. In either instance, the rope will readily unwind from the reel'and will hang' out ofthe window. The bailsfil of'the main body are I now disengaged from the hook 60 and the through the lower portion'of the frame 12 and will climb out of the window. -His I eccentrics 44 -toincrease or diminish 1 his 2 6O andthe loop 58 is engaged with said hook,

weight causes descent of themain body of the device along the rope 22 and the various friction-creating devices hereinbefore described, control the rate of' descent. If de-' sired, the occupantmay operate one of the speed. When one person has descended, *another may pull the rope 22 upwardly, thus again elevating the main body of. the device, tothe fioor from which the descent was made. Then, the loop 59' is removed from'the hook so that the end of the rope having said loop 59 may be thrown 'outof the window. Assuming that the rope engaged the shoe 20, the roller 36 and the parts 44*41', during the preceding descent, said rope will'now'be dis engaged from these parts and will be en-' gagedwith the shoe 20*, the roller 36, the

, eccentric 44, and the lever end 41 at the opposite side of the device, for the second descent. Hence, it'will be seen that the device may be advantageously used as many 'times as desired, in succession, it being only 11.
