To all whom. it may concern i MIcHAEL J. Frrzonn- Be it known thatI,

United-State's, and a ALD, a citizen of 'the Los Angeles and State of California, have invented a new and Improved Fire-Escape, of which the following isv a full, clear, and exact description.

My invention relates to fire escapebal-Q comes a d ladders,

and particularl'y'to a ladder normally supported abovethe first balcony and adapted to be lowered to the street in an emergency. I provide guides on the first andsecond balconies in which the ladder has movement, and a novel device on one balcony which will hold the ladder in the raised position above'thefirst balcony, said device-being readilyzmovable to release the ladder and permitit to be lowered, The invention will be particularly. ex-

' plained in the specific description herein after to be given.

Reference is to be had totheaccompanying drawings forming a part 'of vthisspecifiin which similar characters of refercation, ence indicate corresponding parts in all the views.

bar, which free end constitutes a handle, the

' bar is given such a formation as to provide a lateral extensionto extend beneath 'the ladder rung and sustain the ladder. In the form shown, the bar 14: is formed with aubend 15in an outer-direction immediately ad acent to the pivot 13, such U bend constitilting the lateral extension and the ladder- .engaging member. It will be observed from Fig. 2, thatthe bar 14: may be swiing to ex tend longitudinally of the balcony, with the member 15 extending beneath a ladder rung a. Thus the ladder. may be raised from the v a ground to extend between the first and sec-' ond balconies, as shown in Fig-1', and willthus be sustained in position when there is no occasion for the occupants of-the build :ing to, descend'fron'i the first balcony to the 1 street. Incase oftfire, however, the bar 1 L may be' swnng on its pivot to withdraw the :member 15 from beneath the adjacent ladj'der rung to permit the ladder to drop, the

ladder having movement -in-. .the guides 10 on the twobalconies. The length, ofthe ladder is 'such that when dropped it will still be heldin the guides of the lower :bal cony C, and firmlyj-sustainediiii position to enable the occupants of the building to de-.
