SPECIFICATION forming part of Letters Patent No. 295,465, dated March 181, 1884:. I
Application filed October 24, 1883. (No model.)
T0 aZZ whom it may concern.-
Be it known that I, CHARLES VoN DER LINDEN, of Bhinebeck, in the county of Dutchess and State of New York, have invented a new and ImprovedFire-Escape, of which the following is a full, clear, and exact description.
This invention relates to that class of fireescapes in which the person descends by means of a rope, a brake being provided to which the person clings or attaches himself, and by which he regulates his speed of descent; and the invention consists, principally, of a holder containing two pulleys, and a brake -vplate adapted to act upon the pulleys, the holder being cast in two parts, and one part thereof provided with a screw for operating the brakeplate.
y The invention also consists of the construction, arrangement, and combination of parts, all as hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate cor responding parts in all the figures.
Figure 1 is a perspective view of my new and improved fire-escape. Fig. 2 is a sectional elevation of the same, taken on the line 00 w of Fig. 3; and Fig. 3 is a sectional elevation taken on the line yy of Fig. 2.
A represents the holder; B B, the grooved pulleys placed therein upon the bolts 0 G. D
represents the brake-plate, also placed upon the bolts 0 0 within the holder, and E represents the screw for operating the brake-plate to and from the pulleys B B, and F is the escape-rope, whichpasses through the holder in contact with opposite edges of the pulleys B B, as shown clearly in Figs. 2 and 3.
The holder A is, by preference, made of two hollow castings, a a, held together by the bolts 0 O, and the brake-plate D is, by preference, countersunk, as shown at d d, toreceive the sides of the pulleys B B, so that the plate will occupy small space and yet be of sufiicient strength, and the bolts 6 O are ar ranged on opposite sides of a transverse plane through the center of the holder, as shown in Fig. 2, for holding the pulleys B B out of line with the end openings of the holder for increas. ing the friction upon the descending rope F.
The casting a is formed with the lips b b, and the casting a with the corresponding recesses, c 0, into which the lips I) I) enter when the two castings are put together, thus forming a key to prevent the parts of the.holder from moving out of place with respect to each other, and the castings a a are each formed with the half-openings e e, which correspond with each other and with the diverging lips f f around the said halffopenings, which lips also correspond with each other, so that when the two castings are put together the said half-open- .ings form completecircular openings at opposite ends of the holder for the passage through the holder of the rope F, and the said diverging lips form jug-necks G G at opposite ends of the holder, to which necks the body strap or rope H is attached. This rope H may be in the form of a belt to buckle around the body, or it may be formed with a stirrup, or have both belt and stirrup attached to it, or be constructed in any suitable nanner to enable 'a person to securely cling or'attach himself to the holder A for descending the escaperope F.
In use the rope F will be made fast at its upper end to the window-sill or to some fixed object in the room by means of the loop f. The lower end of the rope F and holder A will then be thrown out of the window and the screw E turned to lock the holder fast to the rope. The person to descend will now attach himself to .or cling to the rope H and holder A and grasp the wheel E on the screw E and turn the screw outward, which will diminish the friction of thebrake-plate D up on the pulleys B B and permit the holder to grad ually slide down the rope. By tnrningthe screw E more or less the person descending may control with perfect case his speed of descent, so that the device is perfectly safe and reliable. In case there should be several persons to descend, the rope F and holder A Having thus fully described my invention, 3. In a fire-escape, the holder A, composed 15 I claim as new and desire to secure by Letters of the hollow castings a a, held together by Patent the bolts 0 O, in combination with the inclosed 1. The case made in two parts, each formed pulleys B B and brake-plate D, placed upon 5 with half openings 6 and diverging lips f at the said bolts, the casting a being provided its top and bottom, and provided with the sewith the screw E, for operating the brake- 2o curing-bolts 0, extending through the case, plate, substantially as described. and having mounted thereon the pulleys and the brake, and a brake-screw, E, substantially CHARLES VON DER LINDEN. '10 as set forth.
