UNITED STATES PATENT OFFIo NICOLAS s. RAG OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN AUTOMATIC FIRE-EXTINGUISHERS.
Specification forming part of Letters Patent No. 173,434, dated February 15, 1876; application filed January 17, 1876.
To all whom it may concern:
Be it known that I, NICOLAS S. BASH, of Boston, in the county of Suffolk and State have invented. certain improvements in Automatic Fire-Extinguishers, of which the following is a specification:
In the accompanying drawing, forming a part of this specification, Figure 1 represents a plan view of my invention, and Fig. 2 is a sectional view of the same.
This invention relates to that class of fireextin guishing apparatus employing a system of stationary pipes adapted to discharge water into an apartment or building when certain checks which usually prevent the escape of the water are removed by fire existing'in the apartment or building. My invention has for its object to provide a simple and efl'ectiveautomatic apparatus for extinguishing fires; andto this end, it consists, first in' a novel combination of parts, whereby caps are held over nozzles or openings in a stationary water-pipe (located in the upper part of an apartment) only by means of a material which is combustible, so that, in case of fire in the apartment, the combustible fastenings are ignited and consumed, and the caps either drop from the nozzles or openings of their own weight or are forced off by the pressi,
ore of the Water, which finds exit and speedily. extinguishes the fire. My invention consists, secondly, in the combination of a combustible cord or connecting medium with the combustible fastenings of the caps, said cord extending entirely around the room and including in its circuitv all the points where the caps are held on the nozzles or openings, so that a lire" in any part of the room near the walls will be likely to effect the uncovering of all the openings -of the waterpipe; all of whichl will now proceed to describe.
In the drawing, a represents a portion of a stationary pipe, which is supposed to extend around the upper portion of an apartment and to be connected with a reservoir of water. At suitable points along the pipe A I provide short branches 1), which are preferably inclined downwardly, and are provided with nozzles or openings, 0, of any desired shape, a spherical perforated nozzle being preferred. d d represent caps adapted to fit over the nozzles 0, each cap bearing at its inner end against a flexible washer or packing-ring,'e, placed against a shoulder, f, on the branch I). The inner ends of the caps 01 are provided with outwardly-projectin g beads or flanges f g g represent radial lugs located on the branches 1), between the shoulders f andthe main pipe, and to these lugs are pivoted arms h, of which I prefer to employ from two to four for each of the branches 1). The arms h are adapted to turn freely on their pivots, and each isprovided with a projection, h, near its inner end. When the capsd are placed over the nozzles, the arms h are turned outwardly until the projections h bear upon the beads or flanges f, as shown in. Figs. 1 and 2, in which position they are held by fastenings, 2', of any suitable combustible fibrous material, wound upon the apparatus in such manner as to bear upon the outer edges of the arms h, which are preferably serrated to prevent the fastenings from slipping ofl. The projections h of the arms h hold the caps 61 securely in place over the nozzles as long as the arms are held in the position shown in Fig. 2. When the arms h are released, however, those on the lower side swing downwardly, and-the caps either drop from. the nozzles or are forced off by the pressure of the water. It will be seen, therefore, that when the combustible fastenin gs t are consumed by fire, the caps will be released and the water rush into the apartment and be widely diffused by the spherical nozzles. I prefer to make the fastenings i of thread saturated with collodion andcoated with gun-cotton. lconnect all the fastenings of the series by acord,j, composed of materials similar tothose of the fastenings, and extending entirely around. the room, so that fire near the wall in any part of the room will be imparted immediately to the fastenings of all the caps, and the latter will be released in rapid succession.
I claim as my inventionl. The combination of the branches b, having the nozzles c and pivoted arms h,
the caps 11, having the beads or flanges f In testimony whereof I have signed my name and the combustible fastenings i, all arto this specification iu'the presenceof two subranged and operating.substantially as describing witnesses.
scribed. NICOLAS S. EACH.
2. The combustible cord j, combined with Witnesses:
the combustible fastenings i, substantially as SAML. M. BARTON,
described, for the purpose specified. G. F. BROWN.
