Specification of Letters Patent.
Patented- Sept. 7,
Application and September 11, 1919. Serial no. aaaocsf 1 To all whom it may concern: v v
.Be it known that we, THOMAS 1-1. MausHAw and CONRAD J. Drnz, citizens of the United States, residents of Baltimore, Maryland, have invented certain new and useful Improvements in Fire-Plugs, of which the following is a specification.
Our invention relatesto an improvement in fire plugs and is designed to provide an attachment which may be carried with the pumping apparatus and connected up with the ordinary fire plug,this attachment com-, prising a head, carrying a pipe connection to the nozzle, a suction connection to the pumper and a return pipe connection under pump pressure to the nozzle, valves also being provided, whereby the ordinary pressure in themain may be utilized or the pressure ofthe pumper.
Our invention also includes a modification which may be permanently connected to the fire plug and utilized to deliver water under the main pressure or through the added pressure of the pumper.
In the accompanying drawings Figure 1 shows in diagram the pumper with the connections to the ordinary fire plug, this view showing the complete connection adapted to be carried by the pumper.
Fig. 2 is a detailed view of the connecting head interposed between the pipes leading to and from the pumper and the fire plug.
Fig. 2 is a detailed view showing the three-way valve permitting the utilization of either the ordinary main pressure or-the pressure through the pumper.-
Fig. 2 is a sectional .View showing the form of valve, taken on line'b-b of Fig. 2"; Fig. 3 is a sectional view showing the gate valves for controlling the flow to the pumper, Fig. 4 is an enlarged view of the head and associated parts. I
Fig. 4& is a detailed view of the gate valve. Figs. 5 to 8 show the modified form of the device adapted to be permanently applied to the fire plug. I
In Fig. 1 the fire plug is shown at A and the head at B, this head having pipe conneetionsto the pumper so as to direct the water through the pumper to the discharge nozzle also carried by thehead B, this head being the supporting mediumifor the three pipes and also connecting with the fire plug, and in the fornmof the invention shown in Fig. 1 it is carried by the pumper as a complete connection and is adapted to be fitted to the ordinaryfire plug when in use. This head has a 560171011 1), as SllOVVIllll Fig. 2,
which in turn has at one end a coupling '1') adapted to be screwed-upon the threaded exit pipeof the fire plug, while at its opposite end it is screw threaded, as at 0,, whe'reit is adapted to receive the threaded end of the suction hose leading to the pumper shown at A gate valve 6 operated in the usual manner by a hand wheel 7 and athreaded stem g, is provided at the rear end of thesection Zr so as to completely close the exit opening to the pumper when it is desired to use the ordinary main pressure which would then pass out through the opening h, Figs. 2 and 3, to the exit nozzle 2'. When the pumper is in action the water passes through the pipe d through the pumper and is returned through the pipe 70 to the exit nozzle, a valve m shown in'Figs. 2 and 2 being actuated through the-spindle n to either permitthe passage of the water under main pressure direct to the discharge nozzle, or by closing the direct pressure opening-h, as in Fig. 2 and opening the gate valve 6 the pressure will pass through the pumper.
In Fig. 4 we show how the pumper may be cut out completelyand the plug pressure used through three sets of hose, namely, by putting a reducer 0 on the end of the section I) and connecting an independent hose p thereto and applying a discharge nozzle to each of the hose pipes 29, 7s and i, shown in this figure. The same head bmay be utilized without change except as to the reducer o and pipe p. i
Instead of carrying thehead b with the pumper and as a detachable connection to the plug, it may be permanently attached tothe ordinary fire plug by mounting it upon the head of the plug without in anyway changing or altering the plug proper as to its ordinary outlets, as shown for instance in Fig. 5 where the plug is indicated at A and the ordinary outlets at 1 and 2.
We utilize the same device sofar as the head B is concerned, except that it is directly mounted upon the head of the plug and the opening from the plug into the head B is through an ordinary valve which is opened or closed through a turning stem 9 which has a lowerend threaded to the valve pass upward in to the head B. i The water then passes "through the opening 0, the
puniper, and back through the opening 70' and thence out through the discharge 2" or a reducing coupling may be applied to c and. an independent discharge pipe to 7c and-the plug pressure used through three independent discharges, as in Fig. 4:.
-to'eut oi"? the arious inlets and. allow the water to be directed either through the piiinpc ',-or direct from the main chamber of the part B, provided, of course, in this 7 latter event the valve 6 tak1n the fJlfttO oi V o 7 I he gate valve is closed.
What we claim is: t l. A. connection for fire plugs comprising head adapted for connection with the plug, said head'having a main pipe for clirecteonnection with the engine, a valve for controlling the {low rioin said main pipe,
tWo couplings supported from the head, one for the return pipe from the engine,
andthe other for the outlet to the. nozzle,
and athree-Way valve for closing the out- 'let from the engine-end making a direct connection from the head to the nozzle to ent out the engine or for causing the flow through the engine When the main outlet tion the dischar e 3inefro1n the en ine substantislly as described. v In testimony whereof We aint: our
