AUTOMATIC FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 680,084, dated August 6, 1901.

Application led December 3, 1900. Serial No. 38,598. (No model.)

To all whom it may concern:

Be it known that we, JosEPH TESSIER and ZOEL SEVIGNY, citizens of the United States, and residents of New Bedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Automatic Fire-Extinguishers, of which the following is a specification.

Our invention relates to that class of eX- tinguishers which are usually secured to the ceilings of rooms in mills and factories; and the object of our invention is to provide such a fire-extinguisher which shall be safe from being accidentally put in operation and which shall be adjustable, so that when in operation to extinguish a lfire the water from it may be made to cover a large or small door-space.

To this end our invention consists in providing a shell for such automatic lire-extinguisher within which all its operating parts are inclosed in such a manner that they are not liable to become displaced by any means except the heat from a re; and it further consists in providing a distributer which may be adjusted within the shell of the extinguisher so as to cause the water from the same to spread over a large or small floor-space.

The accompanying drawings illustrate our invention, in which- Figure l is a side elevation of our improved automatic fire-extinguisher as it appears when adjusted for use. Fig. 2 is a View of the same, showing one side broken away so as to expose its internal arrangements. Fig. 3 is a top view of the distributer, and Fig. 4t is a View in vertical cross-section of the same through the dotted line a: az. Fig. 5 is a vertical section of the bottom part of the extinguisher, showingthe manner of locking the arm within the shell.

Similar letters refer to like parts in the several views.

The letter a represents the shell of our iinproved automatic'fire-extinguisher, having a water-passage a' through its center and provided with the ears h on opposite sides of its lower edge, between which are pivoted, respectively, the dat arms f and g.

The letter c represents the distributer, which is supported in the shell a by and Vertically movable on the screws m, which pass loosely through the apertures s' s and are seated in the body of the shell o, at o o. The apertures s s are counterbored at their lower ends in order that the screws m may not project below the rim of theshell when the distrib uter c is at its lowest position.v The outer edge of the distributer is turned upward and provided with the notches d, which divides and distributes the water over a large space when the water ows through the aperture a. The arm g is provided with the lip p and the arm f with the notch q, as shown in dotted lines, Fig. l. The upper surface of the distributer is provided with a suitable packing o in order that when the distributer c is pressed up against the lower end b of the aperture a it will make a water-tight joint. The distributor ois held up against the end b of the aperture a so as to form a water-tight'joint by the arms g and f pressing against its under side. The arm fis rst folded up and then the arm g, whose lipp catches over the notched end q of the arm f, and the arms are then soldered together with metal which fuses at a low temperature.

The operation of the device is as follows: The device being attached to a water-pipe at the ceiling-of a room and a re occurring in the room, the heat from the fire rises to the ceiling of the room and fuses the solder on the arms fand g and allows them to swing downward and outward on their pivots and the distributor c to drop downward, as shown in Fig. l, until the bottom of the counter-bores' lrrest on the heads of the screws m, thus opening the water-passage a and exposing the notches d in the distributer below the rim of the shell a, and the water rushing through the said notches is divided and distributed over a large floor-space to extinguish the lire. When it is desired that the water shall cover a less space, the screws fm; are adjusted so that the distributer shall drop to a lower point, thus allowing the water freer egress and causing it to spread to a less extent. When the fire is extinguished, it is only necessary to fold up the arms to the position shown in Fig. 2 and resolder them together to put the device again in readiness for use, none of the partsneeding to be replaced with others.

All the operating parts of the device being contained within the shell a, it is not liable IOO to be opened aeeidentaliy by objects moved about the' room, such as ladders, belt-shifters, rico.

Having thus described our invention, what we claim, and desire' to secure by Letters Patslots, one of said arms being formed with a recess q and the other with a lug p, adapted to engage the said recess, said arms being adapted to fold up Within the shell, whereby accidental dislodgment is prevented, said arms beingfsoldered together to hold the distributer against the annular depending flange to make a water-tight joint.
