To all whom it. may concern.- 7 Be it known thatl, OLE HANSEN, acitizen of the United States, residing at Walnut Grove,-in the county of Sacramento and State of California, have invented 'a new and useful F1re-Escape,of which the following is aspeci- .fication.

' My invention relates to"improven1ents in {fire-escapes in which folding ladders are emplayed and so constructed as to conform to the architecture of the building to which they are attached when .the same of use."

Fig. 2 is a side elevation of a portion of the ladder to show the side view of the brace which serves to keep the ladder from swinging or swaying sidewise, and is employed near'the top or bottom of the ladder. Fig. 3

is a plan view of the same as that shown in Fig. 2. Fig. 4 is a side elevation showing 'a portion of the ladder and partially raised as "in. the aetof folding. Fig. 5 is a portion'of the outer rail of the ladder to show theatta-chment of a projection'conforming to a pro Fig. 6 is a side ele -vation of a portion of the ladder, showing a- H raising the same.

pinion and segment attached as one mode of Fig. 7 is a side elevatinn of portion of the ladder with a broken part of the folding platform or window-step. Fig. 8 is a detail View Ora window; showing the folding platformor window-step as it appears when the ladder is opened out, ready for use. Fig. 9 is, aportion of the ladder-strip employed .to attach thefolding ladder to ahouse I already constructed. Flg.j1() is a vertical 3 plan jview;s howing a section of the same as that showhinFig. 9.

Ihe following is the construction-of the same: I'form' the ladder -'of -metal,-the outer of the "ladder when folded up' in the front wall of thebuildinglyattach any suitable employ 'several difierent modes of 'operating "the ladder, according to the construction and arrangement of the house. I raise and lower .or open the same by the segment and pinion 5 1 at D in the inner strip or ladder-rail, E. I

F and G. (Shown in Figs. 4 and 6.) I balance the weight of the outer rail, A, by-the weight H. (Shown in Figs. 1 and 4.) I attach the bell I and arrange the arm or lever J' to strike the same as the pulley K is revolved by the ladder-cord L, passing over it as the ladder opens out. I-attach the platform L" under the windows and pivot it to work upon the same line or axis as the rounds of the ladder, so that when the lad- '70 der is opened out a platform widee'nough to step out upon is just a little below the window-sill, connected with the ladder by the trails M and.N,. leaving a space at the end between the platform and the ladder to pass down through. I employthe portable ladder-strip R with flanges ES to receive the rounds Z. I attaeh'the strip R by means of the bolts V or similar attachment. I

sometimes employ thelever orarm J to .strike or setofl any. well-known coil-spring or other alarm,,so as to makesufiicient noise to alarm the whole house instantly, instead of employing the common bell, I.

The following-is the -.operation' of my fireescape: When a fire is discovered; the segmeut F is operated by means of the pinion G, or any well-known device for throwing the ladder out andvdown until the outer rail, A,

rests upon the ground andthe rouhdsof the ladder lie in a horizontal position. The plat-form L is in position to allow a person to step out upon the platform and descend the ladder between the arms M and N. The platform. L serves as a firm brace to theladderto, 5
