IMPROVEMENT IN MEANSFOR OPERATING VALVES 0F ClTY WATER-MAINS.

Specification forniing part (if Letters Patent N 0. 134,348, dated December 81, 18. 2; Reissue No. 7,964, dated November 27, 1877; application filed January 5, i877.

To all whom 'it may concern: v Be it known that I, HENRY P. M. BIRKIN- BINE, of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain Improvements in Fire-Protection and Operating Valves of Hydraulic Mains, which improvements are fully set forth in the following specification. reference being had to the accompanying drawings. My invention is applicable in cities or towns which are supplied with water that is caused to flow by its gravity from a reservoir, standpipe, or other receptacle into which it is forced by means of a pumping apparatus.

The invention consists in cutting oil the flow of water in the pumping-main at any convenient. pointrheforeritrreachcs the reser voir or other receptacle, and causing it to flow, by the force exerted by the pumping apparatus, through the distributing main or mains, and thence through the fire-hydrants and the necessary hose for extinguishing fires, without the use of the ordinary fire-engines.

I effect this object by connecting, at any convenient point, a distributing main with the pumping-main, and insert valves in each main, so arranged as to have one opened and the other closed simultaneously by means of hydraulic or pneumatic apparatus or elecvalve, U

A is the pumping-main, and l) a distributing-main. G is a valve inserted in the pumping-main at the point a, and (1 another valve, connected with the distributing-1nain at he point a. l) is a cylinder, which is provhcd with a piston, E. F is the piston-rod, at each end of which s jointed a connecting-rod, G, the outer ends of which connect with the crank-arms H H of the valves (3 and C. J

J are pipes, which connect with the ends of the cylinder D, and lead to the pumpingstation, police-station, or any other point from which it is desired to operate the valves. The valves ,are opened and closed by forcing water or other fluid through the pipe J, when it is desired to close the valve (3 and open the valve 0 so as to cut off the flow of water into the reservoir or other receptacle, and to use the fdl'ce of the pumping apparatus to force the Water through the distributing main and when the position of the valves is to be reversed, so as to open the flow of water to the reservoir through the pipe A, and cut off the flow of water through the distributing-pipe B, the water or other fluid is forced through .therpipceliriuio the cylinder-D -Pnenmalie power may be used with the same apparatus, instead of the hydraulic power, for opening and closing the valves; or they may be con-- trolled by means of electrical power. When this power is used, the pipe J is connected with the punipinginain, haying a valve in it which is opened by means of a weight or spring. This is held or kept closed by a keeper at the end of a lever, which is so arranged that when a current of electricity is passed through it, it disengages the lever, and allows the valve to open, when the pressure of water in the main, acting upon the piston in the cylinder 1), reverses the valves 0 and O. A baclcpressure valve must be placed in the main or mains leading from the reservoir, so that when the pressure in the distributinginains becomes greater than thatduc to the head of the reservoir the valve will close and prevent the water iinwing back.

- Fig. 2 represepts anmrdinary form of backprcssure or checkvalve, so; placed in the disof power by means 0f hydraulic or other press The eefety-velve is ieo ledm any desired pressure; end when the preserlre through the pumpis in excess of this, the valve opensv one. allows the water to flow through thepipe into the pumping-main b, and thence into the :re eerroir.

i' to not confine myself to any particular form eif valves es any of the known valves for op enin g and, closing pipes will answer the purpose; nor do confine "myself to the maehanie. ineens' shown for operating thevalves.
