FlRE-ESCAPEQ SPECIFICATION forming part of Letters Patent No. 589,569, dated September '7, 1897.

Application filedMay'10,1897. Serial No. 635,768. (No model.) 7

To alt whom it may concern:

Be it known that I, VENDELIN Mi'J'LLER, of Newark, county of Essex, and State of New Jersey, have invented an Improved Fire-Escape, of which the following is a specification.

This invention relates to a fire-escape which is designed to, be permanently secured to a building, preferably beneath the roof, and which may be drawn down in case of fire, so as to provide ready and reliable means of escape.

In the accompanying drawings, Figure 1 is avertical longitudinal section of my improved fire-escape on line 1 1, Fig. 2. Fig. 2 is a plan, and Fig. 3 an enlarged cross-section on line 3 3, Fig. 1.

Upon the top of a ceiling A and preferably beneath the roof B of a buildingIplace a track a, having flanged longitudinal edges a. The track a serves to support a sliding ladder, the side pieces of which are made sectional and are composed of angular links I), connected at their lower ends by pivots I), while the apex of each-link b carries the round 0. Upon each pivot b there is mounted between everypair of links I) afriction-roll cl to permit a tree sliding motion of the ladder along the track. To the forward end of track a there is secured the doubly-bent hook or stop 6, which serves for the attachmentof one end of a central guide-wire f, that extends longitudinally between the links and beneath the rounds c to a staple g at the rear of the track. The rearmost pair of links b are connected by a bent cross-arm h, which projects beneath the longitudinal wire f( The forward end of the ladder is connected to a pull-rope i, which may be attached to a panel j, that closes an opening in the wall D, the panel being in turn attached to the ladder by bent wire In.

Ordinarily the panel j is closed and the ladder rests upon the track a. In case of fire a pull on rope i will open the panel and Will at the same time draw the ladder forward along the track until its rear cross-arm 7L comes into engagement with the lower bend of hook 6, when the ladder will become arrested andsuspended from said hook ready for use. While the ladder is thus drawn forward the longitudinal wire f will guide the cross-arm h toward the lower bill of the hook, so that an ultimate engagement between hook and crossarm is insured.

' It will be seen that my improved fire-escape is simple in construction, reliable in operation, and ready for instant use.

\Vhat I claim is n In a fire-escape the combination of angular links with rounds at the apexes of the links, a cross-arn1 connecting the rearmost pairof links, a guide extending longitudinally between the links beneath the rounds and above the cross-arm, and a stop to which the for= ward end otthe guide is secured, substan tially as specified.
