Application filed Harch 13, 1889. Serial No. 303,132. (No model.)

To all whom it may concern:

Be it known that I, Edward P. Waggoner, of Syracuse, county of Onondaga, in the State of New York, a citizen of the United States, 5 have invented certain new and useful Improvements in Piping Systems, of which the following is a' specification, reference being . had to the accompanying drawing.

My invention relates to systems for piping io buildings for fire purposes adapted to useau.. tomatic sprinklers and other appliances under pressure.

The object of my invention is to furnish a simple compact system adapted to'use water 15 either from a water-main or from a tank on the roof, and also the filling of the pipes with a'non-freezing chemical or other preparation under pressure.

My invention consists in the several novel 20 features of construction and operation hereinafter described, and which are set forth in the claims annexed.

It is constructed as follows: A is a vertical wall of a building.

13 is the roof, and C D floors thereof. .

Upon the roof I show a tank E, connected to the water-main 1, connected by the vertical pipe 2 and branch 3. In this pipe I insert two stop-valves 4 and 5, 4 being nearer the 30 tank and-5 nearer the first floor of the building, and 6 is a check-valve adjacent to the stop-valve 4. 7 is another check-valve adjacent to the stop-valve 5. To the. stand-pipe 2 the sprinkler-pipes 8 and 9 are connected in. 35 any ordinary manner, and each is provided with a cnt-off valve 10.

are the automatic sprinkler-heads used upon the pipings. - .

• F is a mixing-tank, in which I mix up the 40 chloride of sodium^oT other chemical solutions from the pipe 12? opening out of the tank above the bottom, to allow for settling of the chemicals, carrying the saturated solution into the storage-tank II, whence the pipe 12 · 45 conducts it to the force-pump I, and from this pipe 13 conducts it to the stand-pipe .2. - In th is pipe 131 place a check-valve 14 and stopvalve 15, find·.to this pipe, between the stopvalve and .stand-pipe 2,1 connect the drip50 pipe 16, provided with a stop-valve 17. This pipe is the drainage-pipe, through which I can draw off all the water fn the piping any purpose by shutting the stop-valves 4 and 5. When I have so drawn off the water from the piping, I. close the valve 17’and open the 55 valve 15. To All the system under pressure, the valves 4 and 5 being closed, I then operate the pump and force the prepared liquid through the pipe 13 into the pipe 2, and thence into jthe pipes 8 9, filling them with the solu- 60 tioii and forcing it into’them until the pressure upon the gage 18, connected to the standpipe 2,· indicates a pressure at least equal to twenty pounds per square inch above the pressure from the tank E or pipe 1 exerted 65 upon the stand-pipe 2. The construction of this gage upon the valves 4 and 5 in the main supply-pipe will not be specifically here given, becatiseT intend 'to make it the subject-mat-, ter of a subsequent application, so that I will 70 simply say that the face is provided with an adjustable electrical contact-point, to which one of wires, as 19 or 20 in the circuit shown, is connected, the other wire being also connected to the arbor of the needle in the gage, 75 so that when the needle is in contact with, the contact-point the circuit is complete from the battery 21—one way on the gage and the other way on the bell 22—and from the bell to the gage, so that whenever from any cause 80 the w/iter-pressure in the stand-pipe 2 is reduced by leakage, Jiy the opening of the sprinkler-head, &e.,the removal of the_;needle to the contact-point closes the circuit'and sounds an alarm upon the bell. .· 85

At 23 I show a switch by which I cut out. the bell whenever desired—as, for instance, when I am filling the pipes with the solution, * and also for testing the bell and battery.

It is operated as follows: Having prepared 90 . the non-freezing liquid in the tank or tanks, and the pipes through the building being empty and the valves 4 and 5 being closed and 15 opened, Loperate the pump I, drawing the liquid from the tank and forcing it through 95 the pipe 1-3 into the main pipe 2, and thence into the eeiling-pipes.8 9, filling them and continuing the pumping until the pressure on the gage 18 indicates a pressure of, say, twenty pounds per square inch greater than-the 100 pressure in the water-main 1. Then when the valve 5 is open the water from the main cannot pass upward into the piping against the increased pressure, nor can it open the check417,798 valve 7, and in like manner when the valve 4 is open the check-valve 6 will prevent the . liquid from entering the tank E.. After having obtained this pressure I close the valve 5 15. Then when the pressure, either from leakage or from the opening of an automatic sprinkler-head 11, is reduced the operation of the needle of the gage connected to the battery and bell will sound an alarm upon the io bell 22, and I then know that if a head is off there is a fire in the building, and if not there is a leakage in the pipes, and in case of leakage I restore the pressure by operating the pump. In case a sprinkler-head is open, and 15 the valves 4 and 5 are opened,, the water from the tank E or from the water-main will replace the non-freezing liquid in the pipes and operate to extinguish the fire, atid in case the tUiik E becomes empty all the water will flow 20 fi’dm the water-main, the check-valve 6 preventing the flowing of water into the tank E. It will be observed that thus the stand-pipe, ektei'ior to either Or both check-valves, is norriiillly filled with the non-freezing liquids, 25 which are separated from the fresh water by tile check valve or valves, and that whenever a Sprinkler is opened the check valve or valves Will Open to admit fresh water into the standpipe to replace the liquid discharged through 30 the sprinkler; and it will be further seeii that By keeping the piping full of this liquid there is no danger of the¹ pipes freezing up in the ebldest weather, even in a building in which thfere is no heating apparatus.
