M. HADDAD HIGH PRESSURE VALVE STRUCTURE Filed May 5, 1928 I bz'uentar 2 Sheets-Sheet 2 Patented June 24, 1930 MICHAEL HADDAD, OF SONORA, ARIZONA HIGH-PRESSURE VALVE STRUCTURE Application filed May 5, 1928. Serial No. 275,516.
The present invention relates to an im proved valve structure supplying water, under pressure, to be used for various purposes where high pressure water systems are required.
The invention has reference to a structure which will serve advantageously for supplying water under pressure for fire fighting, for smelters, mines, mills, hotels, and other establishments requiring water under pressure.
Briefly the invention comprises a valve which is connected with the city pressure supply line, the same having a discharge pipe leading to a centrifugal pump, operated by an electric motor, the electric motor being incorporated in an electric circuit having a switch controlled by the action of the city supply valve.
The specific structural arrangement of parts cooperating to produce the improved organization will become more readily apparent from the following descrlptlon and drawings.
In the drawings V Figure 1 is a side elevational view of a valve structure and electric circuit switch constructed in accordance with the present invention.
Figure 2 is a top plan view of the same.
Figure 3 is an enlarged view in section and elevation detailing the valve structure and showing in the diagrammatic way the centrifugal pump, the electric motor and electric circuit.
Figure 4: is a perspective view of a supporting bracket.
Uonsidering now the drawing and referring to the parts by numerals it will be ob served that 1 designates a base upon which the valve casing 2 is mounted. Threaded into the open screw threaded top portion of the casing is a closure 3 provided with a stuffing box in which the stem 4t of a valve 5 is slidable. This valve 5 is slidable in an inner cylinder 6 located in the casing and provided with circumterentially spaced ports 7 through which the water is discharged, the cylinder is connected with a partition 8 having an open- .ing 9 through which the water enters. Incidentally, the city supply pipe is designated at 10, and is connected to one side of the casing, and serves to supply water beneath the partition 8 so that it passes up through the port 9 and out through the port 7. It discharges through a pipe 11 which is connected with additional piping 12 leading to and connected with a centrifugal pump 13 of appropriate construction. Associated with the pump 13 is an electric motor 14: included in an-electric circuit having wires 15 and 16 connected with a suitable source of supply, not shown. The centrifugal pump is also connected with a valved discharge device 17 A Gonfining attention more particularly to Figure 3 it will be seen that there is an arm 18 fastened to the upper screw threaded end of the-valve stem 4 and connected thereto through the medium of nuts 19.
Bolted to the free end portion of this arm is an insulation strip 20 carrying a bracket21 having a retaining screw 22 for connection of the wire 16 thereto. Associated with this bracket is a carrier 22 for a circuit closing roller 23 which is mounted for sliding motion between confining flanges 24 on the upright 25. The upright 25 is or" insulation material and carries a contactplate 26 with which a binding post 27 is associated. The wire 16 is connected with the bracket21 and the wire 15 is connected with the binding post 27. Obviously, when the roller 23 which is of electricity conducting material is in contact with the plate 26, the circuit is closed to the motor 14, setting the motor into operation with the driving centrifugal pump 13. It is yet to be stated that a suitable right angularly shaped bracket 28 is attached to the base 1 and constitutes a support for the upright 25.
In practice, the ordinary city water supply enters the valve through the pipe 10, and passes downwardly and then up through the opening 9 in'the partition 8. In so doing, it braces the valve 5 up to the position shown in Figure 3, thus uncovering the port 7 and allowing the water to pass onwardly through the pipes 11 and 12 into the pump 13. As the valve 5 rises the electric switch is closed, thus closing the electric circuit and operating the motor to drive the pump. This as gspect to a predeterminedamount of presprovides a supply of water under pressure which can be controlled by the regulating valve in the discharge device 17. So long as the water is turned on, the circuit is closed.
As soon as the water is released, the valve.
5 closes. This is accomplished by attaching a cross head 29 to the upper end of the valve stem and attaching coil springs 30 to this. The springs being adjustably connected to the cross head as at 32 and adjustably anchored on the base as at 33.
It is thought that by considering the de scription in connection with the drawings that a clear understanding of the construction, operation and advantages of the invention will be had. Therefore, a more lengthy description is regarded unnecessary.
.Minor changes in the size, shape and rearrangement of parts coming within the field of invention claimed may be resorted to if desired.
Having thus described the invention, what I claim is '1. In a structure of the class described, a base, a valve casing supported on said base including intake and discharge ports, a cylinder in the casing having discharge ports and an apertured valve seat, a slide valve in said cylinder having a valve head cooperable with said seat and ports and a stem extending upwardly through the top of the casing, an upright adjustably mounted on the base including a switch contact, a relatively movable switch contact carried by the valve stem and cooperable with the first named contact, and spring means connected with the valve stem for normally holding the valve head down upon said valve seat.
2. A structure of the class described, comprising in combination, a base, a valve casing mounted on said base, and having intake and discharge connections, a cylinder in said casing, including ports in communication with the intake and discharge connections, a slide valve element including a head slida-ble in the cylinder and a stem extending up through-said casing, a cross head on the upper end of said stem, an arm on the upper end of the stem, a switch element carried by said arm, springs connected with said cross head and anchored upon said base for normally maintaining said valve head in a position to close the ports in said cylinder, a bracket mounted on the base, an upright adjustably mounted on the bracket, and a contact carried by the upright and cooperable with the switch element.
3. The combination with a pump, a motor to operate the same, a water supply, of an electric switch, means controlled by the supply of water for operating the switch to control the operation of the motor whereby the latter will be stopped when the pressure of the water exceeds or is diminished with resure, spring means for normally maintaining the switch in an opened position aga nst the pressure of the water, said switch being further adapted to be moved to a closed position against the action of said spring means, when the pressure of the water is increased or diminished beyond a predetermined point.
4. In a structure of the class described, a base, a valve casing supported on said base including intake and discharge ports, a slide valve in said casing controlling said ports, said slide valve including a stem extending upwardly through the top of the casing, an upright mounted on the base including a switch contact, a relatively movable switch contact carried by the valve stem and coopera le with the first named contact, and spring means connected with the valve stem for normally holding the valve in a seated position within the casing for closing the ports, said valve adapted to be moved to an open position against the action of the spring by the pressure of the water, whereby said movable contact may be moved into and out of engagement with the stationary contact during the movement of the valve, sa1d movable contact adapted to be moved out of engagement with the stationary contact, when the pressure of the water in the valve casing is increased or diminishedbeyond a predetermined pressure.
In testimony whereof I aflix my signature.
MICHAEL HADDAD.
