APPARATUS FOR RAlSlNG LIQLHDS.
SPECIFICATION forming part of Letters Patent No. 597,273, dated January 11, 1898.
Application filed June 23, 1897. Serial No. 641,890. (No model.)
' which the folloivingis a full, clear, and exact description.
lhe object of the invention is to provide a new and improved apparatus for raising liquids by the use of compressed air and in a very simple and economical manner.
The invention consists principally of a reservoir containing compressed air, a Vessel submerged in the liquid to be raised and having a suction-valve and a valved dischargepipe, a pipe having a valve and connecting the said reservoir with the said vessel, and a device for automatically opening and closing the said valve and controlled by the pressure and exhaust of the air in the said pipe.
The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both figures.
Figure l is a side elevation of the improvement, With parts in section; and Fig. 2 is an enlarged sectional side elevation of the aircontrolling valve. 5
The improved apparatus for raising liquids is provided with a vessel A, submerged in the liquid to be raised and provided at its bot-- tom with a suction-valve B for allowing the liquid to pass into the said vessel, as hereinafter more fully described, the liquid being discharged from the vessel through an outlet-pipe 0, having a check-valve O for preventing a return flow of the liquid to the vessel A. From the top of the vessel A leads an air-pipe D, connected with a reservoir E, containing compressed air, and connected by a pipe F, having a valve F, with the cylinder G of an air-compressor, the said cylinder havin g an inlet-pipe H, provided with a valve II". The piston in the air-compressor is driven by a motor I.
In the air-pipe D is arranged a valve J,
having a plug J, formed with a diametrical bore J 2 for forming a straight passage for the air through the pipe D from the reservoir E into the vessel A, and from the said bore J 2 leads a branch bore J adapted to register with an outlet J formed in the body of the valve. On the stem of the plug J is secured an arm J adapted to be engaged by collars K K secured to a pistou rod K, carrying a piston L, fitted to slide in a cylinder N, the said piston being normally held in a lowermost position by the action of a spring 0, coiled on the piston-rod and pressing on the said piston.
The cylinder N is connected at its lower end by a pipe N, containing a check-valve N with the pipe D below the valve J, and a second pipe N connects the lower end of the said cylinder with the pipe above the valve J, and this pipe N is provided with a globe or like valve N for regulating the amount of air passing from the reservoir E directly into the cylin'derN, to act on the piston L therein and to move the latter upward, so as to cause the collar K to swing the arm J and close the plug J and to shutoff the air from the reservoir E to the vessel A. hen this takes place, the lower end of the pipe D is connected by the bore J with the outlet J to permit air to escape from the said pipe D and vessel A to reduce the pressure in the latter and to allow the Water to open the valve B and fill the vessel With the liquid. \Vhen the air exhausts from the lower end of the pipe I), then the valve N opens, so that the air is let out from the cylinder N, and consequently the spring 0 forces the piston L downward,whereby the collar K finally acts on the arm J 5 to again open the valve J and allow air to pass from the reservoir E through the pipe D into the vessel A to press on the liquid contained therein and force the liquid through the pipe C to the desired place of discharge. When this takes place, the pressure of the air pass ing into the pipe N acts on the piston L to again raise the same, as previously described, and to cause an automatic opening of the said valve to the outer air, so as to refill the vessel A, as previously explained.
Thus it will be seen that by the arrangement described the valve 3 is automatically controlled, so as to allow compressed air to and when suelldiseharge has taken place the pass to the vessel A and .foree-the liquid con tained tllerein lthrough the dischargepipe,
air is allowed to escape from the said'vessel to permit the liquid torefill the'same through the suction-valve 13;
Having thus fully described my invention, I claim as newanddesire to secure by Letters Paient v,
1. An apparatus for raising liquids, cam-J prising a vessel'submerged in the liquid to be raised, andv having a suction avalve and a' valved discharge-pipe, an air-pipe connecting the said vessel with a compressed-ail? supply,
a valve in' the said air pipe a device con-x l trolled by the pressure of the air in the said air-pipeand conmollinglthe said valve in the air-pipe, the said'deviee comprising a cylinder connected with the air-pipe above and be low the'said valve a spring-pressedpiston en the said cylinder, and a pistomrod having col the said valve, substantially as shown and described.
- 2QAn apparatus for raising liquids; pro vided with a valve in the Compress'edair-supply pipe, a device for automatically controlllingthe said valve and comprising a cylinder 7 having valved couneetions with the said pipe above and below the said -valve, a piston in larsadapted toaltevnafiely engage anarni on r the-said cylinder, collars held on the :pistonis rod of the said piston, and an arm'adapted to be engaged alternately bythe said collars, to turn the said valve and open and close the pipe, andto connect the lower end thereof with the outer air-,su bstantially'as shevvn an d described. a I
