To all whom it may con/cern:
Be it known that l, MICHAEL SCHWARZ, a subject of the Emperor of Austria, residing at Dresden, in the German Empire, have invented certain new and useful Life-Saving Apparatus to be Used in Oase of Fire, (for which 1 have obtained patents in Germany, No. 58,882, dated December 28, 1890; in Austria-Hungary, No. 698 and No. 15,159, dated April 29, 1891; in Belgium, No. 95,315, dated June 17, 1891; in France, No. 211,750, dated February 27,1891, and in Great Britain, No. 4,478, dated March 12, 1891,) of which the following is a specification.
My invention consists of a rope, line, chain, or cord fitted with a sliding brake and other apparatus, together forming a handy means of escape from iire; and in order that my said invention may be particularly described and ascertained, reference is hereby made to the accompanying drawings, in which similar letters of reference indicate corresponding parts.
Figure 1 is an elevation of my invention. Fig. 2 is another elevation at right angles to Fig. 1. Fig. 8 is a sectional elevation of Fig. 1; and Fig. 4is an elevation, partly in section, at right angles to Fig. 3.
a is a rope, line, chain, or cord formed of any suitable material, and hereinafter called a ccropen b b is a double hook consisting of an open hook b and a snap-hook b. This hook is secured to the rope asA shown.
c is a Weight retained on the free end of the rope a by a knot, as shown in Fig.' 3, or by other suitable means.
d is a coiled spring resting on the weight c for reducing the momentum of a person coming down the rope on nearing the ground.
The brake apparatus consists of a cylinder e, surrounding a portion of the rope and preferably constructed externally of wood and internally with a metal liner. The upper end of the cylinder or liner is fitted with a case f of the form shown in Figs. 1 to 4. One side j" is made to open for examination of the rollers and other purposes. The cover f is hinged at f2 andsecured by the Winged nut and bolt f3.
g are three rollers fitted to the back plate of the case f and round which the rope is placed, as shown in Fig. 3. These rollers may be otherwise arranged. A hand-brake 7c (the block of which is grooved to it the rope) is litted in the cylinder e, pivoted at i, and fitted with a lever-handle h. By means of this brake additional friction may be applied to the rope a when necessary and the descent checked or entirely arrested.
m is a bracket attached to the cylinder e by means of a ring n. o represents a portion of a belt which is secured to the body of a person using the apparatus.
When using the apparatus, the hook b or ZJ is fastened to a bar, balcony, or other suitable fixed part or fitting of the building from which the escape is to be made. The Weighted end of the rope is lowered and-the belt o is secured round the waist, or preferably round the body just under the arms of the person to be lowered, and he can then lower himself at a safe speed to the ground by grasping the handle h, and by pressing the brake-block 7c more or less hard against the rope a he can obtain the brake-power which, in addition to that of the three rollers g, Will serve to secure this result. When nearing the ground, the spring CZ secures a safe landing and neutral izes any shock which might result from reach ing the ground at too great a speed.
1n fitting the apparatus to windows or other openings in buildings the length of the rope is made to suit the height of the Window above the ground, so that the weight c may be just clear of the ground when hanging down.
When out of use, the cord is Wound up in any suitable manner, and the apparatus is kept in a convenient position, ready for use.
I claim@ In a fireescape of the class described, the combination of the cylinder e, the case f, secured to the upper end of said cylinder and having a hinged cover f', a winged nut and bolt for securing said cover in its closed position, a series of rollers g, pivoted in said ease, a hand-brake lo, pivoted at one end to the cylinder and provided with a brake-surface and a lever-handle h, an opening in the side of cylinder e, through which opening the brakesurface of the brake is adapted to project, a bracket m, adapted to be secured to the lower IOO end of the cylinder by a securing-ring n, a belt cylinder, all arranged for co-operation, as de- Io o, secured to said bracket, a rope passing scribed.
through the cylinder and around the rollers In testimony thereof I have hereunto set and out through an opening in the upper end my hand in presence of two witnesses.
of the case f, a snap-hook secured to the upper end of the rope, a weight c, secured to MICHAEL SCHWARZ. the lower portion of therope, and a coiled `Witnesses.: spring encircling said rope and located be- HERNANDO DE SOTO,
