ALBERT MARSHALL PUTNAM, OF VOBURN, MASSACHUSETTS, ASSIGNOR TO THE PUTNAM PUMP COMPANY, OF MAINE.

WATER-ELEVATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 555,122, dated February 25, 1896.

Application filed January 3, 1895.

To @ZZ whom it may concern:

Beit known that I, ALBERT )lARsHALL PUT- NAM, a citizen of the United States, residing at lVoburn, in the county of Middlesex and State of Massachusetts, have invented certain new and useful lmprovem ents in Tater-El evating .if-ipparatus, and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in water elevating or pumping apparatus, and its novelt-y will be fully understood from the following description and claim when taken in conjunction with the annexed drawings, in which- Figure l is a vertical section of my iinproved apparatus. Pig. 2 is an enlarged detail section of a portion of the pump.

Referring by letter to the drawngs, B indicates the pump, and O the motor for actuat-ing the pump.

As shown in Fig. l of the drawings, the casing D of the pump B is of a special construction, being formed in two parts, and it comprises the base or main section E, in which is formed the receiving-chamber e, the piston-cylinders f, the ports g, connecting the receiving chamber e and the cylinders f, and the passages 7l leading from the pistoncylinders above the ports g and the section F, in which is formed the air or discharge chamber i. This section F is mounted upon the section E between the cylinders f and is secured in any approved manner, and it is provided, as shown, with a nozzle j, whereby a ready connection of the discharge-pipe may be eeeted.

j" 7e indicate the upwardly-opening valves of the pump, which control the ports g and passages 71, respectively, and m on indicate the pistons which are arranged in the cylinders f, as shown. These pistons m. m are connected to rods n, and these rods are connected in turn to the ends of a rocking-beam p, whereby it will be seen that when said beam is actuated the pistons will be reciprocated in their respective cylinders.

ln the practical operation of the pump it will he seen that when one piston-the piston Serial No. 533.712. (No model.)

m', for instancemoves upwardly, so as to draw water from the receiving-chamber e into its cylinder, the other piston, m, will move downwardly and seating the valve j and opening the valve 7o will force all of the water which it had drawn into its cylinder by its preceding upward stroke into the air or receivin'g chamber i and out through the discharge-pipe. Thus, when the pump is in operation, the water is forced in a steady and continuous stream, which is a desideratum.

G indicates the main frame of the motor of my improved apparatus. This main frame comprises, by preference, the upright bars g and the transverse bolts r connecting the same, and it affords bearings for the several shafts H, l, J, K, and L comprised in the motor. The shaft H is provided with a crank s, which is connected by a pitman t to a crankbranch vu of the rocking-beam p, and motion is transmitted from the drive-shaft K to said shaft H through the medium of the gearwheel M on the shaft K, the pinion N and gear-wheel P on the shaft J, thepinion Q and gear-wheel R on the shaft l, and the pinion S on the shaft H. The gear-wheel M is loosely mounted on its shaft K, but it is provided with a spring-pressed pawl T, adapted to engage the ratchet-wheel U, which is fixed on the shaft. By this construction it will be seen that when the shaft K is rotated in the direction of the arrow the wheel M will also be rotated and motion will be transmitted to the pump through the medium of the train of gearing described.

Mounted on the shaft K, but within the frame, is the gear-wheel Y. This gear-wheel meshes, as shown, with the pinion Z on the shaft L, and this shaft is provided, as shown, with a crank M', whereby it maybe readily rotated in the direction indicated bythe arrow.

In order to prevent freezing of water in the pump and consequent damage thereto, lprovide the mechanism better illustrated in Fig. 2, through the medium of which any water that remains in the piston-cylinders f, after the pump has stopped, may be permitted to pass back into the well or other source of supply. This mechanism comprises the levers a2, which are fulcrumed upon hangers depending from the pump-casing, rods b2 con- IOC) nected to the outer ends of the said levers and extending through stuffing boxes c2 and adapted to engage the valve j', a bar (Z2 arranged between the conduits h and above the receiving-chamber e, rods e2 connecting said bar d2 and the inner ends of the levers a2, and a spring interposed between the upper wall of the chamber e and the bar d2 and adapted to normally hold said bar and the parts connected therewith in the positions illustrated in Fig. 2. By reason of the construction described it will be seen that when the pump is not in operation, and it is desired to drain the water from the piston-cylinders f, it is simply necessary for the attendant to press downwardly upon the bar d2, when the valves j' will be raised and any water in the said cylinders f will be permitted to pass into and through the receiving-chamber c and back into the well or other source of supply.

Having described my invention, what I claim is- The pump described comprising the base or main section E, having the receiving-chamber e, the piston-cylinders f, the ports g, connecting the receiving-chamber c, and the cylinders f, and the passages leading from the piston-cylinders above the ports g, the section F, in which the discharge-chamber is formed, the upwardly-opening valves j, controlling the ports g, the upwardly-opening valves k, controlling communication between the passages h, and the discharge-chamber7 pistons arranged in the cylinder f, the bar cl2, arranged above the receiving-chamber e, and between the passages 7L, the levers a2, fulcrumed below the receiving-chamber e, rods connecting the inner ends of said levers and the bar cl2, rods connected to the outer ends of the levers CL2, and extending through the receiving-chamber e, and engaging the valves j', and a spring interposed between the upper wall of the receiving-chamber e, and the rod cl2, and adapted to normally hold the said bar and the rods connected therewith in such a position that they will not interfere'with the operation of the valves when the pump is in use, substantially as specified.

In testimony whereof I afx my signature in presence of two witnesses.

ALBERT MARSHALL PUTNAM.
