JOSEPH R. BROWN, OF PROVIDENCE, RHODE ISLAND.

AUTOMATIC FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 257,549, dated May 9, 1882.

Application filed November 11, 1881.

To all whom it may concern Be it known that I, JOSEPH R. BROWN, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Automatic Fire-Extinguishers and I hereby declare that the following is a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, forming a part of this specification.

The invention has reference to an improvement in distributers for water, arranged to open automatically; and it consists, first, in a deflector, perforated or not, which is secured by a metal fusible at a low temperature, and which, when released, will spread the water issuing from the outlet.

It further consists in providing such a deflector with a stem,on the upper end of which is a valve or plug, by which the outlet is closed and the water is prevented from reaching the soldered joint.

Figure 1 is a view of one form of my improved automatic fire-extinguisher. Fig. 2 is a sectional view of the same, showing the position of the distributer. Fig. 3 is a sectional view of a distributer provided with a non-perforated deflector.

In the drawings, A is a piece of pipe, provided with the valve-seat b at its upper end, into which, or against which, the valve 0 is held by the stem d, the lower end of which is providedwith a screw-thread and the extreme end slotted,sothat it can be turned in the nut formed in the distributer E. A 1ock-nut,f, may be used to firmly hold the stem. The stem at is held in the center of the pipe A by the guides shown in the drawings, and near the outlet end of the pipe A a surface, 9, is formed on the pipe, to which the distributer or deflector is secured by a solder fusible at a low temperature.

The valve 0 may be in part formed of a material fulsible at a low temperature, so that this valve itself will melt before a fire can get much headway, if by any means the fusion or melting of the solder by which the distributer is secured to the pipe should fail to release the valve. Such an emergency may arise, though (No model.)

not at present apprehended. The melting of the valve 0, or part of the same, will allow the water to flow to the distributer E, and when the same is perforated, as shown in Fig. 2, will be discharged on the. fire.

The device, as shown, is secured and made ready for attachment in the shop, the valve 0 closing the inlet, and when attached to the usual pipe-fittings in a building it is to be pendent from the pipes. As the water cannot pass the valve 0, the soldered joint 9! is not affected by-the same, and will melt, or at least fuse enough to release the distributer from the pipe, and, as the full pressure is acting on the valve, the distributer will be projected downward and held suspended below the outlet by the valve resting on one of the guides, as is shown in Fig. 2. The water willbe discharged downward and sidewise through the holes in the distributer, as shown in Fig. 2 5 or it will be thrown against the ceiling and spread in every direction, if the unperforated conical deflector is used, as shown in Fig. 3.

This automatic fire -eXtinguisher is much more prompt in its action than those in which the water can come in contact with the fusible solder or with the metal to which the seal is secured by fusible solder, as in this extinguisher the solder is removed a considerable distance from the water.

The pipes conveying water to the distributers can be secured close to the ceiling and the distributer be screwed into the fittings so as to be suspended below the pipes. The ceiling will thereby be perfectly covered with water and assist the distribution of the same.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In an automatic fire-extinguisher, the combination, with the pipe A, provided with a contracted outlet and an annular soldering-surface, of the valve 0, constructed to exclude-the water from the distributer, and a conical distributer secured by solder, as described.
