Specification of Letters Patent.

Application filed April 12, 1909. Serial No. 489,315.

To all whom it may concern:

Be it known that I, ADnLBnRT OswALD MULLER, a citizen of the United States, and a residentof Presho, in the county of Lyman and State of South Dakota, have invented a new and Improved Fire-Escape, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved fire escape for use on dwellings, hotels and other buildings, and arranged to insure a safe and quick escape of persons from the building, the latter being provided for this purpose with permanent poles for engagement by a slide arran 'ed for su ortin a erson at the time- Figure 1 is a front elevation of a building provided with the improvement; Fig. 2 is a side elevation of the same; Fig. 3 is an enlarged front elevation of the support and slide; Fig. A is a side elevation of the same; and Fig. 5 is an enlarged perspective view of one of the braces for a pole.

One or a number of poles A are suspended at their upper ends from brackets B or a like device attached to the building C at or near the roof thereof, as plainly indicated in Fig. 1, one of the poles extending in front of window openings E, and one or more poles extending in front of door openings F. Each of the poles A is held against movement by one or more braces D pivoted to the face of the building C, and having a forked spring end D engaging the pole, as plainly indicated in Fig. 2, thus holding the pole from swaying.

A person intending to escape from the building by one of the poles A from a window E or a door F makes use of a slide Gr, consisting essentially of a snap hook H and a support I, pivotally connected at H to the snap hook H, so as to allow of adjusting the snap hook H and the support I at an angle one to the other, (see upper portion of Fig. 1 and dotted lines in Fig. l). The snap hook H is adapted to be snapped onto the pole A and the support I is provided with a handle I adapted to be taken hold of by the person intending to escape, the support I also having a foot I adapted to rest on the pole a distance from the point engaged by the snap hook H. The foot I has a forked terminal so as to readily keep the foot in engagement with the pole A. The handle I of the support I extends a distance beyond the fulcrum H, so that the weight of the person hanging on the handle I holds the snap hook H and the foot I with more or less friction in contact with the pole A, to insure a proper downward movement of the slide on the pole with the person hanging onto the handle I. Now according to the special conditions of the case, the snap hook H and the support I are set at more or less inclination one toward the other, and for this purpose the pivotal end H of the snap hook H is provided with apertures H ar ranged in a circle around the pivot H, and a cotter pin J or a like device is adapted to pass through one of the said apertures H and through a corresponding aperture in the foot I Thus by the arrangement described, the snap hook H and the support I can be readily adjusted one relatively to the other. Now when a person slides down the pole A with the snap hook H and the foot I engaglng the pole, as described, and the person hanging onto the handle I, then a proper descent is had, and the foot I in coming in contact with one of the braces D swings the latter downward out of engagement with the pole A, so that the person can readily land on the sidewalk.

In order to aid a person to readily engage the slide G with the pole A, each window E is provided with a handle K, and a step L is arranged on the outside of the building a distance below the sill of the window. At a door opening F use is made of rings N connected by flexible supports N with the top of the door opening, so that ersons standing in the door can take hold with one hand of the ring N and with the other of the slide G so as to engage the snap hook H with the pole. If a person tries to escape from a window, he takes hold of the handle K with one hand and steps onto the step L, and then applies the slide G to the pole, after which the person releases the hold on the handle K and steps off the step L with a view to slide down the pole.

The hook H is preferably provided at the apertures with numerals, thus enabling the person making use of the device to readily set the snap hook H and the support I, one relative to the other, according to the special conditions.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A fire escape, comprising a pole spaced from the wall of the building, and a slide having a hook for engagement with the pole, and a support at an angle to the hook and adapted to rest against the pole.

2. A fire escape, comprising a pole spaced from the wall of the building, and a slide having a snap hook for engagement with the pole, and a support at an angle to the said snap hook andhaving a handle and a foot adapted to rest on the said pole.

3. A fire escape, comprising a pole spaced from the wall of the building, and a slide having a snap hook for engagement with the pole, a support pivotally connected with the said snap hook and having a handle, a foot adapted to engage the pole, and means for adjusting the support relative to the said snap hook.

4:. In a fire escape, a pole arranged in front of the building and suspended at its upper end, braces pivoted to the face of the building and having forked ends engaging the pole, and a slide for engagement with the pole, the said braces being adapted to be swung downward out of engagement with the pole When the slide contacts therewith.

5. A fire escape, comprising a pole suspended at its upper end and spaced from the wall of the building, a slide having a hook for engagement with the pole, and a support pivotally connected with the hook and having a member provided with a forked terminal for engaging the pole.

In testimony whereof I have signed my nameto this specification in the presence of two subscribing witnesses.
