CHARLES H. CARY, or 'RRisTon RHODE ISLAND.
A ROTARY PUMP.
SPECIFICATION forming part of Letters Patent No. 374,731. dated December 13, 1887. Application iled February 16, 1886. Serial No. 192,161. (No modelll T0 @Z6 whom, it may concern:
Be it known that I, CHARLES H. CARY, of Bristol, in the county of Bristol and State of Rhode Island, have invented a new and useful Improvement in Rotary Pumps for Wells or Cisterns, ofwhich the following is a specification.
In adapting a rotary pump for use in raising water from wells or cisterns it is desirable to place the pump in the well below the reach of frost and to force the water upward through a connecting pipe, and it is also desirable to regulate the height of the water remaining-in the pipe after the operation of the pump, so that the level of the water therein may be held belowv the limit of frost in the well, or at any other required point in the discharging-pipe; and lmy invention consists in the combination of the rotary pump with an outwardly opening pressure-operated relief-valve at its suction side, whereby upon the reversal of the movementof the'pump the waterwill be forced from the normal discharging side of the pump to the suction side, and thencev by forcible pressure under the relief-valve, thus preventing the freezing of waterin the pipes, and also in means for adjusting the pressure of the relief-valve upon its seat, whereby the water may be retained at any required heightin the discharge-pipe without requiring a reverse action of the pump.
Figure 1 is a sectional representation of a well in which is placed a pump provided with my improvements. Fig. 2 is a detail vertical section of the pump, showing the relief and check valves in the suction-pipe. Fig. 3 is a vertical section of the crank-standard and dischargespout. Fig. 4 is a detail vertical section of the upper end of the cranlcstandard,
vshowing the hand-crank and. the operating bevel-gears. Fig. 5 is a horizontal section of the rotary pump,taken in the line :c x ofFig. 2.
In the accompanying drawings, A is a reversible rotary pump, which may be preferably constructed as shown and described in my pending application No. 177,122, filed September 14,1885, a transverse section of the same being shown in Fig. 5; but the special construction of the reversible rotary pump is not material to my present invention, and a suitable pump of different construction may be employed.
To the rotary head B, which carries the reciprocating piston C, is secured the shaft D, the upper end of which is provided with a bearing, a, at the upper endof the crankstandard H, and with the attached bevel-gear E, which engages with the bevel-gear F upon the transversely-directed crank-shaft G. The crank-standard H is provided with the dischargespout I and with the conduit B', at the lower end of which is secured the dischargepipe J, which connects `with the pump A and surrounds the shaft D.
At one side of the pump A is placed the airchamber pipe K, and to the ange c, at the suction side of the pump, is secured the pipe L, provided at its lower end with the checkvalve dand at its upper end with theweighted y.
relief-valve e, which may be properly guided -to its seatf by means of the longitudinal ribs g on the valve-stem h and the surrounding walls of the discharge-opening i. To an eye, j, at the upper end of the valve-stem 71 above the weight M, is secured the rope or chain N, passing upward over the fixed pulley O, and upon the downwardly-extending end 0 of the rope or chain N is secured an adjusting-weight, P. A covered opening, k, is made in the wellcover Q, through which access may be had for the purpose of adjusting the weight P, as desired.
The rotary head B of the pump is provided diametrically with a chamber, m, in which is placed the piston C, which is adapted to draw the water into a portion of the chamber m, and to eject it therefrom upon the proper rotation ofthe head B. The piston Gis provided with a centrallyfarranged slot, at, which is adapted to receive the stationary eccentric p, by means of which the piston G will be reciprocated during the revolution of the head B. In. arranging the pump for operation in the well the weight M may be made of suflcient size to cause the valve e to support a column of water greater than the height of the spout I of the standard H. Then, although the ro-v tary head B is made to t loosely in the case of the pump, the water will be retained at the height of the spout I, so that the water will instantly -fiow therefrom upon the proper `movement of the crank R; and if itis desired `I OO to maintain the column of water at a lower level in order to prevent freezing, then, by attaching a weight, P, of the proper size, to thel end o of the rope or chain N, aspecio portion of the weight M will be couuterbalanced, so that the relief-valve e will be raised by the pressure of the column of water in the discharge-pipe, the Water escaping from the same past the loosely-ntting rotary head, and passing out at the opening i until the proper equilibrium has been secured between the pressure' of the relief-va1ve e to its seat and the column of water in the discharge-pipe J.
Instead of the rope or chain N and pulley O, a suitably-guided rod may be extended from the stem of the relief-valve to a point conveniently near to the opening k in the well- CHARLES H. CARY.
