To all whom it may OO Embracing the peripheral edges of the Be it known that we, WILLIAM T.

One of the journals of the drum is extended through and beyond the side of the frame, where it is made angular in form, as at 19, and adapted to receive a suitable key or crank 20, whereby the drum may be turned and the cable wound thereon in readiness for another to use.

By reason of the band-brake engaging both flanges the cable is effectively housed upon the drum, protected from the accumulation of dust and dirt, and said cable is confined upon the drum and prevented from becoming accidentally unwound or loosened thereon. The cable is passed around the pin 7 in the hand-grasp to provide atension for the same and prevent the possibility of any slack therein, as will be understood.

The present device provides a very useful and convenient portable fire-escape, as it is light and durable, is compact and takes up very little room, and is completely under the control of the operator when descending from a window.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the present invention.

Having thus described the invention,what is claimed is 1. In a fire-escape, the combination of a frame having a fixed hand-grasp located at the upper end thereof, a drum having opposite peripheral flanges and mounted below the hand-grasp and within the frame, a cable or rope wound upon the drum and passing upwardly through the hand-grasp, a bandbrake embracing the peripheries of the flanges and having one end fixedly connected to the frame, a bell-crank lever mounted upon the frame and connected to the opposite free end of the brake-band, and operating means connected to the lever and located alongside of the hand-grasp in reach of the fingers of the hand that grips the handgrasp, substantiallyas shown and described.

2. In a fire-escape, the combination of a frame having a fixed handgrasp at its up- .per end, adrum having opposite peripheral flanges mounted within the frame and below the hand-grasp, a cable or rope Wound upon the drum and passing upwardly through the hand-grasp, a band-brake embracing the peripheries of the flanges and having one end fixedly connected to the frame, a bell-crank lever pivoted to the lower end of the handgrasp, a link connected to the free end of the brake-band and pivoted to the adjacent end of the lever, and an operating-handle connected to the lever and located alongside of the hand-grasp, substantially as shown and described.

3. In a fire-escape, the combination of a frame having a hollow fixed hand-grasp at the upper end thereof, which is open at the lower end and throughout one side thereof, and provided with a transverse pin located within the hand-grasp and intermediate of the ends thereof, a drum located below the hand -grasp and having peripheral flanges mounted within the frame, a rope or cable wound upon the drum and passing upwardly through the hand-grasp and around the pin thereof, whereby a tension is provided upon the cable, a brake-band embracing the pe ripheries of the flanges and having one end fixedly connected to the frame, a bell-crank lever pivoted within the hand-grasp and projecting through the open lower end thereof, a substantially U-shaped link connected at its bend to the free end of the brake-band, and having the ends of its sides embracing the adjacent end of the bell-crank lever and pivoted thereto, and an operating-handle connected to the opposite end of the lever and projecting through the open side of the hand-grasp and located alongside thereof, substantially as shown and described.

4. In a fire-escape, the combination witha frame having a fixed hand-grasp extending above the top thereof, and a pendent suspending device or seat for the operator, of a drum mounted Within the frame, a rope or cable wound upon the drum and passing upward through the hand-grasp, a band-brake frictionally embracing the drum, and an operating-lever carried by the frame and located adjacent to one side of the hand-grasp and adapted to be operated by the hand of the operator which engages the hand-grasp, substantially as shown and described.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
