VALVE AND VALVE-OPERATING DEVICE FOR AIR-PUMPS.
SPECIFICATION formingpart of Letters Patent No..651,081, dated June 5, 1900.
Application filed June 80,1899- Serial No. 722,454. (No model.)
To all whom it may concern-.-
Be it known that I, HARRY J. MYERS, a resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Valves and Valve-Operating Devices; and I do hereby declare the following to be a full, clear,
The object of the invention is to improve valves of the general character described; and the invention consists in the construction hereinafter described and pointed out.
In the accompanying drawings, Figure 1 is a section of the device applied to an air-pump. Fig. 2 is an enlarged section of the improved valve. Fig. 3 is a similar section of a modification of the valve.
Numeral 1 denotes a valve-easing, 2 a piston or spindle valve, and 3 a valve-operating lever having a fulcrum in the valve-ease bracket 4, provided with lever-stops 5.
6 and 7 denote, respectively, an inlet and outlet of the valve-casing, and 8 a vent or casing-discharge.
The valve 2 has a lengthwise-disposed port 9, closed at its upper end and open below and communicating with a transverse port 10, extending through one side of the valve to said port 9, as shown.
11 and 12 denote circumferential ports formed in the valve, and 12. is a transverse port by which circumferential port 12 and longitudinal port 9 communicate. A fluid under pressure, such as water from a main, enters inlet 6 and when the valve is suitably situated passes about said valve through port 11 and out at 7 to a pump or the like to actuate the same. This water admission and pressure can be cut off by lowering the valve so that port 11. does not register with the inlet G. If the valve be lowered so that port 10 registers with the outlet 7, the water or other and in usual manner.
fluid which has done its work can be discharged through said port 10 and port 9. the fluid is not to be discharged, port 10 can be dispensed with and the lower end of port 9 closed. The pressure of the fluid admitted by the valve may be utilized in any known or desired manner, as by a rod, piston, bar, or the like part 13, to be suitably connected to a pump or other mechanism as, for eX- ample, to a piston or plunger 23, working in a cylinder 23, the piston being fixed to the bell 2th of an air-pump having in general the well-k nown form of a gasometer.
14 denotes a barv fixed to the bell and provided with tripping-fingers l4, cooperating with valve-moving mechanism, which comprises a rod 15, pivoted to the valve-lever at 16 and suitably guided, as at 17. 18 denotes pins fixed on said rod in the path of an arm 19' of a weighted bell-crank lever 19, having a fulcrum at 19".
2O denotes a weight adjustably connected to lever 1:).
As shown in the present instance, the bar 13 forces upward the bell 24. to draw in air at 25, the bell being raised by means of piston 23, forced upby the fluid admitted through the valve beneath said piston. The pistonrod and the bell, to which it is secured are lifted until the lowerfinger 14' turns the bellcrank lever 19 and carries its weight beyond the center of its are of movement, whereby said weight falls by gravity and lifts thevalve to close circumferential port 11 by moving it out of registry with the valvecasing inlet and outlet. If desired, the construction may be as illustrated and so that the escape-ports 10 may register with outlet 7 to permit wastage of the motor fluid that has been used. The pump-bell being thus raised is filled with air through inlet 25, provided with a check-valve Vhen suitably filled with air, the bell is returned by gravity, its weight being augmented by supplementary weights, if required. The descent of the bell forces its contained air (orother fluid) to any desired point through a suitable valve conduit or conduits 26. The admission-valve 2 remains closed until the descent of the bell carries the upper finger 14' of rod 13 against the arm 19 of lever 19 and lifts the weight, carrying it over until it drops and turns the ICO lever on its pivot to cause its arm 19 to strike the lower pin 18 with the effect to reopen the valve and admit the motor fluid to repeat the operation.
In case the improvement is applied to a construction not requiring the return of waste water through the valve a single transverse spindle-port 1O (see Fig. 3) will be used, and of course such single transverse port will not communicate with a waste-port, such as 9. The upper circumferential port 12 may have such communication or not, as desired under particular conditions of use. Said port 12 receives leakage from below and maintains lubrication of the spindle. It also obviates leakage at the upper part of the spindle-cylinder. In the form preferred a surplus of water leakage into port 12 is discharged through port 9. The port 12 not only arrests water forced upward about the spindle and prevents leakage at the top of the valve-casing, but it arrests sediment that would otherwise wear the spindle or stem of the valve above said port. The construction enables packing or a stufiing-box to be dispensed with, and the valve works freely in all ordinary extremes of temperature without sticking and without injurious wear and leakage.
It is not essential that the valve-lever be supported on a bracket fixed to the valve-casing nor that the steps which limit the path of the lever be a part of the bracket-arm. Neither is it essential that the guide for rod 15 and the weight-rest 21 be integral with or fixed to the bracket, such as 24, which supports the beltcrank lever, though the constructions illustrated are suitable and in many cases preferred. These and other details may be varied, provided the substan tial principles of operation and construction are preserved.
