IMPROVEMENT IN AUTOMATIC SPRINKLERS FOR EXTINGUISHING FIRES.
Specification forming part of Letters Patent No. B69A22, dated N ovr mber 2, 1875 application filed August 21, 1875.
To all whom it may concern:
Be it known that I, HEZEKIAH GoNANr, of Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and Improved Automatic Sprinkler for Extinguishing Fires, of which the following is a specification In the accompanying drawing, Figure 1 represents a side elevation of my improved automatic sprinkler for extinguishing fire in factories', &c.; and Fig. 2, a bottom view of the same.
Similar letters of reference indicate corresponding parts.
The object of my invention is to provide for cottonand other factories an improved sprinkler that discharges the water automatically from different parts of the ceiling When the heat reaches a certain point, so that the "alve connection with the supply pipe is thrown into operation.
The invention will first be described in connection with drawing, and then pointed out in the claim.
The automatic extinguishers hitherto used were sealed by a plug and a composition that melts at a certain degree of temperature, at which the plug is dropped and the water discharged. These fire-extinguishers, however,
are not reliable, as they are apt to get out of working order in course of time by the growth of fungi, rust, or other causes, requiring also after a fire and after testing the rescaling with the composition, which is not always convenient and on hand.
My invention is designed to furnish an extinguishing device that is positively reliable in operation, may be tested at any moment, and placed into the required position with great facility and case.
In the drawing, A represents the watersupply pipe at the top or ceiling, which is provided, at suitable points and distances, with down ward-extcndin g discharge-pipes A, according to the dimensions of the rooms. Each pipe A is provided with a suitable valve, whose stem 0 is extended in horizontal direction, and guided in a tightly-sealing side bearing, a, of the discharge-pipe. The lower part of the discharge-pipe is arranged with a sprinkler, B, that distributes the water in diiferent directions. The outer end of the horizontallysliding valve-stem is provided with a slightly curved and grooved T- bearin g, D, over which and a similar bearing, D, in diametrically 0pposite direction from the former, a skein, E, of cotton of such thickness is wound that the valve is firmly retained on its seat. The hearing or support D is applied to a stationary arm, 0 of discharge-pipe A, and the cotton or other suitable inflammatory material stretched tightly on the supports by means of a screwsleeve, 0 that turns on a thread of the valvestcm, and in a socket-recess of bearing D, so as to act on the same and secure the perfect closing of the valve.
As soon as the flames reach the valve holding cotton skein, so as to burn the same, the valve is forced open by the pressure of the water thereon, and the water is discharged in all directions on the fire.
The sprinkler may be tested at any moment by simply cutting the cotton skein, and instantly be readjusted by winding a new skein around the bearing, and adjusting the stretch' ing screw-nut.
In this manner a reliable, simply-0perated, and inexpensive extinguishing device for factories, store-rooms, 850., is furnished, which may be quickly placed in working order, and perfectly relied upon, either for testing or in case of danger, as the parts are not liable to get out of order, and secure a positive action of the same.
Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination of discharge-pipe A, havin g stationary arm with the T- bearing D, and the end-threaded sliding valve-rod having T- bearing D, as vWell as nut 0 with the flexible connection E, as and for the purpose specified.
