R. S. BOLGER MOTOR TRUCK SPRINKLER AND FLUSHER Filed July 15, 1920 u W M i 5 lllh p n WITNESS l/WE/V TOR l lit. lll ti ll at ROBERT S. ROLE-ER, OF NEW YORK, N. Y., ASSIGNQR TO INTERIG'FTIONALMUTOE GOM- PANY, OF NEW YORK, N. "ii, A CORPORATION OF DELAXVARE.
MOTOR-TRUCK SPRINKLER AND FLUSHER.-
Application filed July To all whom it may concern:
Be it known that I, Rosana 8. Boreas, a citizen of the United States, residing in h ,w York city, in the borough of Manhattan.
city of New York, in the State of New York, have invented certain new and usetul Improvements in Motor-Truck Sprinklers and Flushers, of which the following is a specification, reference being had to the accompanying drawings, forming; a part hereof. I
In motor truck sprinklers and flushers one desirable construction involves the control of the water pump through the main vehicle clutch. One objection to such construction, however, is that when the main clutch is thrownout no power is applied to the water pump and, further, the pump pressure varies directly with the vehicle speed. It has been proposed to employ a construction in which the crank shaft is connected through an independent clutch with the pump shaft, but this construction is somewhat involved mechanically, requires a duplication of parts. and is more expensive. The object of the present invention is to provide means in association with sprinklers and flushers, for maintaining the nozzle pressure even when the pump itself is disconnected from the driving shaft or has its speed reduced. In accordance with the present invention there is provided an auxiliary pressure regulatina tank in which a supplemental supply of water is maintained under constant pressure and is discharged under such pressure automatically whenever the pump pressure falls. This auxiliary regulating tank receives water from the main vehicle tank and has such water stored up under pressure derived from the main water pump during normal operation thereof. The improved construction is at once simple, relatively inexpensive, and mechanically certain, being automatic in its regulation. Reference is to be had to the accompanying drawings for detailed description of two suitable embodiments of the invention in which Figure l. is a view in side elevation of so much of a motor truck sprinkler and flusher as is necessary for an understanding of the present improvements.
Figure 2 is a view, somewhat schematic, and in perspective, of a somewhat modified arrangement of tanks.
The main water tank a is provided with a 1920. Serial No. 395,984.
filler opening I) through which water is re ceivedand a discharge pipe 0 leading to a water pump d. The pump (Z may be driven from the propeller shaft (5 of the vehicle, the rotation of this propeller shaft being); controlled by the main vehicle clutch 7, all in a manner well known. The water pump w] discharges through a pipe 6 to the sprinkler and flusher nozzles 9 located in any desirable arrangement to the vehicle and constructed in any approved manner. Each of these nozzles g is carried on a pipe 9 in which may be mounted a manually operated cut-oft valve From the pipe e leads a pipe section 6 to an auxiliary pressure regulating tank It constructed and mounted the vehicle frame in any desired manner. The tank h preferably communicates with the atmosphere through a vacuum valve h" which closes the tank port when the pressure within exceeds atmospheric pressure. Between the pump (Z and the branch pipe 0 is preferably provided, in the pipe 6, a check valve 01 of any approved type. Between the branch pipe e and the nozzles g is preferably mounted a pressure regulating valve 70 by which the nozzle pressures are limited at all times.
When the main tank a is filled water is free to flow into the auxiliary regulating tank h under the pressure of the head within the tank a and until the valve 72." is seated by the pressure within the tank 71,. Viththe hand valves opened and the pump (Z operating water will be discharged past the re ducing valve in to the nozzles g at the predetermined pressure for which the valve k is set. This pressure will usually be substantially-lower than. the pump pressure with the result that a quantity of water is pumped through the branch pipe 6 into the tank h until the pressure within the tank is substantially equal to the pump pressure. Accordingly, when the pressure of the pump cl falls to any degree the water within the pipe 6 passing through the reducing valve 70 will be subject to the additional pressure inipressed thereon from within the tank 11. Indeed, when the pump cl is stopped entirely the flow of water from within the tank 72 through the branch pipe 6 and the nozzles g will continue at relatively high pressures decreasing constantly, however, until no greater than the pressure for which the reducing valve 70 is set. It will be understood,
1 tion.
of course, that since the auxiliary pressure tank is entirely of a reserve character it will not ordinarily be called on to furnish a supplemental supply for such an appreciable time as to exhaust the pressure therein. The
reserve tank will be useful such times as the vehicle is actually stopped or the pressure;
"tanks H disposed at opposite sides of the tank A and connected through branch pipes E with the main discharge pipe E. The other features of construction and operation correspond with those described with *pz'irticularity in connection with the con struction illustrated in Figure 1.
Other ways of practising the lnventio-n will suggest themselves to one skilled in the art but all modifications entailing mere mechanical skill are to be deemed within the scope of this application provided the advantageous results are realized in substantial accordance with the principles herein set forth.
I claim as my invention:
In a mot-or: truclesprinkler and fiusher in combination, a main water tank, a sprinkler pipe communicating with the main: tank, a pump in the sprinkler pipe an auxiliary pressure regulating water tank, apipe connection from the auxiliary tank to thesprinkler pipe, a checkvalve in the sprinkler pipe between the-pump and said pipe connection, a vacuum valve in the auxiliary tank operable at atmospheric pressure to close the said tank to the atmosphere, and
a pressure reducing valve in the sprinkler
