FLUID-CONTROLLING DEVICE.
Specification of Letters Patent.
Patented Oct. 17, 1911.
Application filed May 3, 1910. Serial No. 559,200.
To all whom it may concern:
Be it known that I, HARRY W. EIsENBIsE, a citizen of the United States, and a resident of Reading, in the county of Berks and State of Pennsylvania, have invented oertain new and useful Improvements in Fluid- Controlling Devices, of which the following is a specification.
My invention relates to that class of devices, wherein the pressure of the fluid is automatically controlled and is especially intended for controlling the flow of water in high pressure fire mains and my objects are, first--to provide a simple and eflicient mechanism that may be attached to a fire plug and which will automatically maintain a constant discharge pressure when the supply pressure may be of a variable nature, second,to provide va means of relieving any excess discharge pressure, third,- to provide a mechanism that when the discharge pressure drops abnormally low the water supply will be automatically cut olf, fourth,to provide a means to drain the hose of water when the said third means actuates.
1With these objects in view, my invention consists of certain novel features of construction and arrangements of parts as will hereinafter be more fully described and pointed out in the claims, reference being had to the accompanying drawing forming part of' this specification and in which,
Figure 1 is a longitudinal section on A-B, Fig. 2, showing the arrangement of the piston, Fig. 2, a vertical sectional elevation on C-D, of Fig. 1, and showing the arrangement of the controlling mechanism, Fig. 3, a plan view of the controlling levers, Fig. 1, a plan of the top of the valve showing more clearly the automatic cut oft' arrangement and the controlling lever, Fig. 5 a view showing more clearly in detail the automatic valve controlling the cut ofi' mechanism and Fig. 6 a section through the valve 37 and showing more clearly the port arrangements of said valve for placing a hereinafter mentioned piston 40 under the influence of a supply pressure, or relieving the pressure by opening up to the atmosphere.
Referring to the figures in which similar numerals of reference refer to similar parts throughout the several views, the numeral 1 designates a suitable casing to which is secured by threaded engagement the member 2. Said member 2 is provided with a reduced portion 3 which is threaded and y plurality of sectors similar in number and contour to the apertures 6. Said valve 7 is positioned on the high pressure side of valve seat 5 and is in fixed relation or integral with the shaft 8 which extends perpendicularly through the axis of the valve seat. 9 designates a lever arm keyed to the said shaft 8 by the key 10. It is evident that the actuation of the lever arm 9 will move the valve 7 so that the sect-ors thereof obstruct the passage of the water through the apertures 6.
10 designates a cylinder integral with the casing 1 and is positioned on the discharge pressure side thereof.
11 designates a piston adapted to fit snugly in the cylinder 10 and to which is ful crumed the arm 12 by means of a pin 13. Said arm 12 is fulcrumed to the lever arm 9 at the extremity thereof by the pin 14;. It is evident that the actuation of the piston due to the influence of the discharge pressure will actuate the leaf valve 7 through its connecting levers. 15 designates a cylinder head secured to said cylinder 10 by means of the screws 16. 17 designates a lever arm fulcrumed in the base of said cylinder and extending vertically therefrom through an aperture in the top thereof. 18 designates a link pivotally connected to said piston 11 by means of the pin 19. Said link 18`is also pivotally connected to said lever arm 17 at some pointintermediate of the fulcrum thereof and the upper portion of the cylinder.
20 designates a pull rod adapted to move in a plane parallel to the movement of the piston 11 and is pivotally connected to the lever arm 17 by the pin 30. 24 designates a similar pull rod adapted to move parallel to the movement of a relief valve 26 and is pivotally connected to the lever arm 27 by the pin 29. 23 designates a rod extending across the top of the valve in a parallel plane to the said pull rods 20 and 21 andis supported at each end by means of the members 33 and 34 which are in screwed adjustment with the casing 1. 25 designates a wrist plate provided with a stem 44, extending therefrom and adapted to pass perpendicularly through the said rod 23 and more clearly shown in Fig. 3. Said wrist plate is pivotally positioned on the l.top of the valve by means of a boss 43 engaging with a recess on the under side of the wrist plate 25. ,It is obvious that said rod is in fixed relation in respect to any longitudinal movement. Said pull rods 20 and 24 are each provided with an upt-urned portion provided with an aperture through which the said rod 23 passes, the said aperture acting as a guide therefor.
21 designates a push rod pivotally connected to the top of the wrist plate 25 and provided with an upturned portion. Said upturned portion is provided with an aperture through which said rod 23 is adapted to pass and said upturned portion is adapted to engage with the upturned portion of the pull rod 20. 22 designates a similar push rod to 21 and is pivotally connected to said wrist plate 25 at a point opposite to the arm 21 and extends in an opposite direction thereto. Said push rod 22 is provided wit-h an upturned portion provided with an aperture through which the said rod 23 is adapted to pass. 31 designates a helical compression spring surrounding the said rod 23 and positioned intermediate of said upturned portion of the pull rod 20 and the screwed member 33. It is evident therefore that any pressure acting o-n the piston 11 inside of the casing 1 will be opposed by the said spring 31 and that said opposition can be adjusted by compressing the said spring 31 by means of the screwed member 33, it being understood that sufhcient clearance is obtained longitudinally inside of the screwed member 33 to permit of a longitudinal movement of the said screwed member 33. 32 designates a similar helical compression spring to that of 31 and is positioned at a point intermediate of the upturned portion of the pull rod 24 and the screwed member 34. It is obvious that any pressure exerted on said relief valve 26 will be opposed by the compression of the spring 32 and that said compression can be varied by moving the adjust-able screwed member 34 longitudinally along the said rod 23.
41 designates a suitable handle rigidly attached to t-he stem 44 of the wrist plate 25. It is obvious therefore that the valve 7 may be closed and the relief valve opened by manual means by turning the wrist plate 25 in a clockwise direction by the handle 41 which forces the pull rods 20 and 24 back by reason of the push rods 21 and 23 engaging therewith. Said movement when the valve is idle will be opposed by the said springs 31 and 32 but said opposition will be balanced when the valve is in operation by means of the discharge pressure acting on the piston 11 and the relief valve 26.
39 designates a` cylinder located on t-he top of the valve casing 1 and is integral therewith. Said cylinder is provided with a. piston 40 to which is pivotally connected a piston rod 42 by means of the pin 50. Said piston is positioned in such a manner as to enable the said piston rod 42 to be conveniently pivotally connected to the handle 41 by means of the pin 43. It is obvious therefore that an actuation of the said piston by means of a pressure will force the wrist plate in a clockwise direction and close the said valve 7 and open the said relief valve 26, it being understood that the force exerted is suliicient to overcome any opposing force.
35 and 36 designates a supply pipe to some source of pressure and 37 designates a valve inserted therein. Said valve when in a position as shown in Fig. 4 is adapted to close the pressure supply to the piston 40 from the supply pipe 35 and adapted to open to the atmosphere the pipe 36 thereby relieving any pressure acting on the piston 40. A predetermined angular movement of said valve will however open the supply pressure to the pipe line 36 and close said pipe line 36 to the atmosphere. The valve 37 is of any Vof the commercial valves well known to the art wherein a port in the cock is in communication with either a pressure supply or the atmosphere. 59 designates the cock of said valve 37 and which is rigidly secured to the said handle 51 but free to turn in the body of said valve-upon the movement of the handle 51. The said cock 51 is provided with a port 5S as shown. 60 designates a port in the body of said valve 37 and which is in communication with the atmosphere. As shown, the pipe 36 connected to the piston 39, is in communication with the atmosphere and atmospheric pressure is necessarily acting on the piston 40. It will be evident that upon the movement of the handle 51 the port 58 can be closed to the atmosphere and upon further movement can be opened to the pressure in the supply pipe 35 and which will be transmitted through the pipe 36 to the piston 40 51 designates a tubular handle for the valve 37 the outer portion provided with a nut in screwed relation therewith. Inside of said handle is adapted to fit a plunger 53 provided with a reduced portion 38 which is adapted to pass through an aperture iii the nut 52. 47 designates a helical compression spring inside of said tubular handle and engages with said plunger to force the same out. Said valve 37 is positioned on top of said casing 1 in such a manner that the plunger 38 slidably engages with a back turned portion 54 of the pull rod 20.
45 designates avgage' in conection with the high pressure side of the mechanism and 46 designates a similar gage in connection with the low pressure side. The gages enable the operator to visually observe the condition of the pressures.
I-Iaving described the various parts throughout the several views all of which will be readily understoodby those skilled in the art to which this invention relates, its operation will be substantially as follows. It will be assumed that the pressure of the supply source is higher than that desired by the discharge and that the reduced portion 3 of the member 2 is secured by screwed relation to a fire plug. ater will enter the valve in the direction as shown by the arrow and pass through the apertures 6 in the valve seat 5. The pressure of the water will act on the piston 11 and force it back. in a manner to close the valve. This force as aforesaid is opposed by the compression spring through the levers 18, 17 and pull rod 20 and said piston will move to such a position until a balanced condition is met. It is obvious therefore that the degree of compression of the helical spring 3l governs the position of the piston 1l which position governs the amount of opening of the valve 7. By moving the screwed member 33 longitudinally, it will effect ai variable degree of compression and the piston l1 will respond thereto in a manner to operate the valve 7. The pressure being predetermined, the operator at the valve moves the screwed member 33 in such a position that the valve 7 is in the proper position to give the desired pressure and which will be visually indi cated by the gage 46. It is obvious that any change in pressure on the supply side of the valve will cause a corresponding change of pressure acting on the piston 11 which will respond in a manner to keep the pressure on the piston balanced with the pressure previously set on the compression spring 31, thereby effecting a constant pressure on the discharge side of the valve and accomplishing the heretofore first mentioned object of my said invention. After the said pressure on the discharge side of the valve has been adjusted, the compression of the spring 32 is relieved by means of moving the screwed member 34 in a longitudinal direction until the discharge pressure balances the action ofthe spring 32. It is evident that any excess pressure on the discharge side of the valve will force the relief valve 26 to open thereby relieving said excess pressure and thereby accomplishing the heretofore second mentioned object of my said invention. On the off position of the valve, the spring 3l forces the valve 7 open and the spring 32 forces the relief valve 26 to seat and close, also the valve 37 is placed in a position to close the supply line 35 on the abnormal condition due for instance to a hosebursting, the pressure on the piston 11 would be relieved and the valve would tend to open wide due to the reasons previously described and which will force the pull rod 20 in a direction to cause an angularmovement of the valve 37 due to the plunger engaging with said pull rod 2O which would place the piston 40 under the influence of the pressure in the line 35. This pressure acting on the piston 4() will force the wrist plate in a clockwise direction, causing the pull rods 20 and 24 to diverge which action will move the piston 1l in a direction to close the valve 7 and open the relief valve 26. Any water that may have remained in the hose will be drained through the relief valve 26 which will enable the hoseman to handle the hose without the weight of water that would otherwise be therein and thereby accomplishing the heretofore 3rd and 4th mentioned objects of my said invention.
I do not Wish to limit myself to the exact construction of the apparatus as shown, as it is evident that departure can be made therefrom without departing from the spirit and intent of my said invention, but- What I claim as new and desire to secure by Letters Patent is l. In a fluid controlling device of the character described, a casing, a valve governing a port in a wall thereof, a piston under the influence of the discharge pres sure, said piston operatively connected to said valve, auxiliary means for actuating said piston, means to adjust the said discharge pressure and mechanism adapted to actuate said auxiliary means upon a sudden abnormal drop in the discharge pressure.
