AUTOMATIC-BALANCE HIGH-PRESSURE PUMP.
Specicaton of Letters Patent.
Application filed March 20, 1911.
To all whom it may concern:
Be it known that I, FRANK M. BUDLONG, a citizen of the United States, residing at San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Automatic-Balance High-Pressure Pumps, of which the following is a specication.
This invention has reference to an automatic balanced high pressure pump and storage tank adapted, among other uses, to be advantageously employed for spraying trees, all substantially as shown and described and particularly pointed out in the claims.
In the single figure of illustration of the invention forming apart of this specification, there is shown a vertical sectional elevation of the complete device or apparatus and which comprises a liquid storage or pressure tank T having an outlet 2 at its bottom with which a pipe or hose can be connected for any purpose according to the use that is made of the device for the time being. Along with this tank I provide means for forcing liquid into the same against accumulating atmospheric pressure therein, and have so constructed the parts that the said pressure can be utilized to assist in the hand operation of the liquid pump and balance the pressure. Thus, C represents a pump or pump cylinder and P a piston or plunger therein having to do with forcing the liquid into tank T. The said cylinder is shown as supported upon a base B of cast metal, in this instance, and having liquid channels therein with an intake through pipe E and running first to the base of the pump and thence past the two check valves V and V to the tank T. Said valves are located in especially constructed cages or cribs indicated by 3 and I respectively and located one directly over the other and in this instance constituted of separate parts set into the main casing or base B. Each cage has its ball valve, above noted, adapted to seat by gravity and to open successively under the action of the pump. Entrance of the liquid as it passes valve V is by short pipe or coupling 5.
M. represents a motor cylinder located in line with pump cylinder C above and apart therefrom and supported from base B en rods or uprights 6. A piston N in cylinder M is connected with piston or plunger P by a rod or bar It, and said parts together are adapted to be reciprocated by means of hand operating lever L. This lever is pivoted on base B at 7 and has a crank arm 8 extending inward to a point substantially in line with piston rod R with which it is connected by link or links 9 and a trunnion or trunnions 10 about midway lengthwise on said rod and at a point above cylinder C relatively about as shown. The lever L has a swinging back and forth movement on its pivot 7 yand both the pump and the motor are operated simultaneously thereby. The first `essential of this operation of course is the iforcing of the indrawn liquid into tank or receptacle T past the check valves V and V', `and incident to this and as an auxiliary `agency or force we have the action of the `compressed air upon the pneumatic motor. `The said motor is connected with the top or dome of tank T by means of a pipe line G, in which are two shut-0E valves g and g', the valve g controlling the flow in pipe Gr between the pump and the tank, and valve g serving as a how-off or open vent valve as operations may require. For example, if for any reason, the valve g should be closed the valve g could be opened and the said motor would run idle while the liquid pump is at work. Otherwise, with valve g closed and valve g open in operation any accumulated pressure of air in the top of the tank by reason of filling in of liquid from beneath would react on piston N and thus assist in depressing the plunger P and in a measure balance or equalize the downward action with the upward action of said plunger. Thus a more or less uniform resistance is established which the operator has to deal with through lever L and certain compensations of pressure are obtained especially when otherwise the down stroke of the liquid pump would be hardest. Obviously the ultimate object of all the above mechanism is to create and maintain a sustained atmospheric pressure in tank T with a quantity of liquid therein so as to force a uniform stream of liquid from the bottom of the tank to the spraying device, not shown, but which may have connection with opening 2. The pressure of air on the pis ton N from expansion of the whole volume of compressed air in tank or chamber T is available to assist the operator in discharging the liquid from the pump at a higher pressure than would be possible without such assistance.
In the operation of a pump of the type shown the operator stands erect facing the pump. The greater force could be applied to the handle by the forward movement of the handle causing downward or pressure movement 'of the liquid piston. The ratioI of the area of the pistons would therefore vary from any fixed constant according to the height, weight or strength of the operator. By actual practice it is found that this variation as to the application of the operating power is slight, and that the average person can, with convenience, apply twice the power on a forward or downward movement as compared with a reverse movement Iby reason of the added weight of the trunk of the operator together with the natural training of the muscles of the body and limbs to forward movements. Therefore I establish the ratio of the cylinders, theoretically, to the ratio of the ease of the average operator in the expenditure "of power in order `to equalize the labor.
For the convenience of operators other than average, and in order to provide proper equalization of energy expended by such operators the valveg can beslightly closed or. fully opened to permit checking of the air flowing from the cylinder tothe chamber M and the reverse or -'the freer flow as the case may be to give a delicate and actual equalization for all operators according to their' fancy.
What I claim is: p
1. In a pump and liquid storage mecha-1 nism, a tank adapted to receive liquid `'under pressure, a manually `controlled pump out-` side said tank adapted to force liquid intoj the tank and amotor under pressure from the tank operatively .connected with saidg pump and adapted `to assist inthe operations; of the pump.
2. .A tank and a pump outside thereof and; a fluid Ipassage connecting said parts andv provided with a plurality of valves, in combination with an auxiliary power mechanism adapted to utilize the atmospheric pressure in the tank to lighten the operations of the pump and comprising a separate chamber and a piston therein mechanically connected with said pump.
3. A tank and pump mechanism adapted to force liquid into the same, a hand lever toV operate the pump and a separate pneuvmatic motor having a chamber open to the tank and a piston therein connected to the pump.
4. A fluid storage tank and a pump arranged to force fluid into the same under pressure, in combination with a pneumatic motor having air connection leading to said tank and provided with an operating connection united with said pump, and a device to operate said pump and motor simultaneously, whereby when the pump is forcing fluid into the tank the air under pressure is utilized by the motor to lighten the operations of said operating device.
5. A tank adapted to receive fluid under pressure, a lpump having a piston to force the fluid into the tank and a valved connection uniting said 'tank and pump, in combination with a pneumatic motor having open 'communication with the tank and provided with a piston of lesser piston area than the lpump piston, and a power device to reciprofcate both pistons simultaneously.
6. A liquid storage tank and a pump out- :side the tank arranged to force liquid into the same, a motor having valve controlled pressure connections with the top of said 2tank and operatively connected with said pump and a hand lever to operate the pump.
In testimony whereof I aflix my signature j1in the presence of two witnesses.
