HYDRAULIC CONTROL VALVE Filed Feb. 19 1951 Fig/ llllll 26 Francis E. Horton Lew A" M d INVENTORS BY WM M4 Patented Jan. 27, 1953 2,626,631 HYDRAULIC CONTROL VALVE Francis B. Hotton, Salisbury, Md., and Lewis A. Medlar, Qrl'an'cLPa.
Appiicationl 'ebruary 19, 1951, Serial'No. 2113338 Thep'resen't invention relates to improvements inhydraulic control valves and more particularly to the type of valve which is well adapted for use in connection with turkey troughs and the I like for controlling the amount of fluid fedto the trough.
An object of the present invention is to provide a hydraulic control'valve having a tubular housing provided with first and second bores and an apertured partition wall therebetween and a ball valve disposed in the first bore for engagement with the valve seat disposed "on the partition wan, and means for selectively displacing theball valve for-permitting flow'throug'h'thehousing and preventing flow through the housing in response to displacement of the trough.
A further object of the present invention is to provide a novel means for unseating the ball valve whereby when the means moves upwardly a predetermined distance in unseating the ball valve, a valve portion of the means engages a second seat for preventing further flow through the housing.
Still another object of the present invention is "to provide a means for adjusting the means for unseating the ball valve whereby the ball valve will be actuated upon predetermined movement of the trough for engagement with the valve unseating means.
Still other objects of the present invention will more fully appear in the detailed description to follow. The best form in which I have contemplated applying "my invention is clearly illustrated in the accompanying drawings,v wherein:
Figure 1 is a side elevational View of :the hydraulic control valve associated with a turkey trough;
Figure 2 taken substantially along the plane of line of Figure '1; and
Figure 3 is a vertical transverse sectional view taken substantially along the plane of line 3-3 of Figure 1 with parts broken away.
Referring more particularly to the drawings, wherein like numerals designate like parts throughout, the numeral l designates generally the hydraulic control valve means and the numeral [2 designates generally the turkey trough with which the hydraulic control valve means is associated. The hydraulic control valve means It is comprised of a tubular housing It, tail pipe means l6, resilient support means 18 for the turkey trough l2 and valve unseating means 20.
As seen best in Figure 1, the trough means I2 is a vertical transverse sectional view 2-2 2 is comprised of an elongated substantially rec tan'gular trough having a flange 22 formed at'i'ts upper peripheral edge. The reactangular trough '25 is pivotally supported on the beam 26v having the fulcrum 28. The hydraulic control valve means It] is connected to a fluid inlet conduit 30 and supported thereby. The hydraulic control valve In has its valve housing [4 formed. from a non-circular tubular member having first and second bores 32 and 34, respectively, -with an apertured partition wall 35 disposed therebetween. The first bore 32 is formed with internal'threading 38 whereby the tubular housing M can be supported on the externally threaded conduit 30.
Seated on the apertured partition "wall 36 is an annular valve seat 45 formed fromsuitable valve seat material having rubber-like resiliency. A b'all'v'alve 42 is disposed in the first bore 32 and engageable with the valve seat 40 for preventing flow through the housing 14, "the valve 42 being downwardly urged against the seat 49 by means of the fluid pressure from the inlet conduit 30.
The second bore 34 is internally threaded at 44 whereby thel tail pipe means It having the external threading 46 can be threaded into the valve housing M for support thereby. The upper end of the tail pipe 16 engages a gasket 48 which abuts the shoulder '59 to provide an effective seal for preventing'flow out around the tail pipe 16.
The valve unseating means 29 is comprised of 'anelong'ated rod 52 which is internally bored and threaded at 54 throughout a substantial portion of its length. An adjustingscrew 55 i'sreceived in thebore 54 with 'a'lock nut 58 foradjustably positioning the adjusting; screw 55 with relation to the actuating rod 52.
The valve unseatingrod 52 'is formed with a tapered valve portion 69 which is adapted to engage the gasket 48 upon predetermined upward movement of the valve unseating means '20. The rod 52 terminates at its upper end in a reduced diameter portion 62 which has its end portion disposed in the annular "seat 41] when the valve unseating rod is in its lowermost position. The means for maintaining the valve unseating means 20 in its lowermost position consists of the snap ring 64 which is engaged on the reduced diameter portion 62 of the rod 52 and engageable with the gasket 48 for limiting the downward movement of the rod 52.
The tail pipe It has a lock nut 66 engaged thereon for abutment against the lower end of the tubular housing 14 for preventing disengagement of the tail pipe from the housing. The tail pipe I6 also has a spring retainer 68 threaded thereon with a lock nut I associated therewith for adjustably positioning the retainer 68 in preselected relation to the tail pipe 16. A coil spring 12 is disposed on the spring retainer 68 to provide a supporting means [8 for the disk 14 seated on the upper end of the coil spring 12.
The disk 14 is provided with a pair of upwardly extending flanges 16 having open ended slots 18 therein whereby the hanger rod 89 may be supported on the disk 14.
The hanger rod 80 is comprised of an elongated and arcuated resilient rod having a bight portion formed with a loop 82 for positioning around the tail pipe I6, the leg portions 84 and 8B of the hanger 89 terminating in arcuated ends 88 and 90 for resilient clamping engagement with the flanges 22 of the trough l2.
In view of the foregoing, the manner in which the hydraulic control valve operates should be readily understood by one skilled in the art. The trough I2 is clampingly supported at one end on the hanger 83 and is pivotally supported on the fulcrum 28 at its other end. Inasmuch as the trough is relatively light from lack of water, thespring 12 will urge the trough to its uppermost position for engagement with the rod 56. The rod 20 will be upwardly urged to unseat the valve 42 and the tapered valve portion 60 will be engaged against the valve seat gasket 48, thereby preventing flow through the housing i i to the tail pipe and trough. When it is desired to fill the trough, the trough must be manually urged to compress the spring, thereby causing the rod 20 and the tapered valve portion 50 to move downwardly to an intermediate position. Fluid will then flow into the trough. When a predetermined amount of fluid has entered the trough, the trough can be released and the valve will trough to maintain it at a predetermined level.
Thus as the trough becomes heavier by the added fiuid, the spring i2 will become compressed and the trough will lower to a position out of engagement with the rod 59, thus permitting the clos-. ing of the valve 42, and preventing further fluid flow through the housing, as seen best in Figure 3.
It will therefore be seen that should the trough be accidentally disconnected from the control valve the valve will automatically close and practically no loss of fluid will occur. Furthermore, the trough can be removed for cleaning Without the necessity of turning the fluid on at some remote point. The bight portion 82 of the hanger J89 need only be unhooked from the supporting disk It for removal of the trough and hanger.
In view of the description and drawings of the hydraulic control valve, it is believed that one skilled in the art Will understand the various other uses to which the invention can be adapted.
