PUMP.

To all whom it may concern:

Be it known that I, ALBERT N. Coornn, a

. citizen of the United States, residing at Baton, in the countyof Colfax and State of New Mexico, haveinvented a newand use ful Pump, of which the following is a specification.

' The present'invention relates to improvements in pumps, the primary object of the invention being the provision of a novel arrangement of pump and actuating mechanism of the type to be submerged in a body of water and especially adapted for use in connection with irrigation.

A further object of the present invention is the provisionof a plurality of reciprocatorypumpscarried by a base to be submerged and having a novel form of actuatingmechanism whereby two of the pumps are connected in tandem and a single operating mechanism will actuate any number of pairs, of pumps simultaneously.

Withthe foregoing and other objects in.

view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changesin the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure 1 is a side elevation of the complete pumping mechanism disposed within a well. Fig. 2 is a top plan view of the complete pumping mechanism. Fig. 3 is a longitudinal sectional view through one pump cylinder and a portion of its actuating mechanism. Fig.4: is a detail view of the main operating gear for all of the pump pistons. Fig. 5 is a top plan view of the same. Fig. 6 is a perspective view of one of the operating connections between a pair of oppositely disposed pumps.

Referring to the drawings, the numeral 1 designates the wellin which is disposed a platform 2, preferably made annular in plan and having the respective legs 3 for supporting the base above the bottom of the well. The annular portion of the base provides a means for supporting the pump,

while the frame or platform l is the support for the operating mechanism of the Specification of Letters Patent.

thereupon the spools 9 having the rims 10 and 10 respectively. A small gear 11 is disposed to mesh at all times with the main gear 7 and is carried upon the main operat-' ing shaft 12, which is journaled in the platform 4 and also in the sleeve 13 carried by the tripod 14, the upper end of the shaft 12 being provided with the large bevel pinion 15 disposed above the ground and in operable connection with the small pinion 16carried by the main power receiving and actuating shaft 17 provided with a pulley or other operating mechanism 18.

Secured upon the platform at and carried by the two pairs of supports 19, are the par: allel guide plates or strips 20 which provide a guide and support for the sliding reception of the pump actuating plate 21, which, as shown, is provided with the transversely and centrally disposed elongated. slot 22 (Fig. 6) which is adapted to surround one of thespooled portions 9 of the main opere ating gear 7, so that when the gear 7 is rotated, a reciprocatory movement will be imparted to the plate 21 within its grooves 20. The two pairs of supports 23 carry the respective guides or plates 24 which are similar to the plates 20 and are disposed at right angles .thereto and there'above, as clearly shown in Figs. 1 and 2. Disposed for reciprocatory sliding movement between the guides 24, is a plate 25 which is similar in I that the rotation of the gear 7 will impart simultaneously to both of the plates 21 and 25 the proper reciprooatory movement for actuating the plungers or pistons of the respective pumps 29.

Each of the respective piston or plunger actuating plates 21 or 25 are provided with the two apertures 26, as clearly shown'in Fig. 6, in which are disposed the hooked ends 27 of the plunger actuating rods 27 Eachone of these rods are constructed simi+ larly and pass through the stufiing boxes 28 of the respective pump cylinders 29. By

this means, it will be seen that the rods 27 of the respective pumps have a reciprocatory movement imparted thereto which is substantially in a tagential line to the periphery of the main operating gear 7 and are so positioned as to receive the maximum thrust and power from the reciprocatory movement imparted to the respective plates 21'and 25 due to the offsetting of the respective rods 27 as clearly shown in Figs. 1, 2 and 6. Disposed within the front cylinders 29 and connected to the inner end of the piston rods 27 as clearly shown in Fig. 3, is a piston 30 provided with the valve 31, while also disposed within each cylinder is a partition 32, the port of which is controlled hy the valve 33, so that the reciprocation of the piston within the cylinder will draw the water in through the perforated disk 34 sealing the end of each cylinder 29 and finally through the valved piston into the reduced chamber 35 and through the branched conduit 86 to the main eduction pipe 37 of the pump. By this means the inlet ends of the respective pumps will be disposed at the periphery of the annular platform 2 and will provide a means for straining the trash, such as leaves, grass and sticks from the water and is finally emitted from the eduction pipe 38 to be directed to the proper irrigating ditches.

From the foregoing description, taken in connection with the drawings, it is evident that with a pump and actuating mechanism constructed according to and embodying the present invention, that all of the respective pistons of the pumps will be operated with the least possible amount of power,

due to the positioning and mounting of the respective actuating plates 21 and 25, and the operating of said plates through a single gear such as 7 Vhat is claimed is:

The combination in a pump mechanism, of a supporting structure consisting of a circular disk platform carrying an intermediate substantially rectangular supporting plate, two pairs of co-acting guides mounted upon the rectangular plate and at right angles to each other, one of said pairs of guides being above the other pair, and a plurality of pump cylinder retainers carried by the circular portion of the plate; a power shaft journaled concentrically of the rectangular disk and upwardly through both pairs of guides, a gear mounted upon the lower end of the shaft and below the pairs of guides, a plategslidably mounted between each pair of guides, said plate being provided with a transversely and centrally disposed slot, a pin connected eccentrically to and carried by the gear and entering the slot of both plates, whereby the rotation of the gear imparts a reciprocatory movement to both plates within the guides, and two pumps connected to each of said plates and secured to the circular plat-form.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
