PUMP.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed August 3, 1904:. Serial No. 219,383.

To all whom it may concern:

Be it known that I, SoLoMoN S. WHIPPS, a citizen of the United States, residing at Lesueur Center, in the county of Lesueur, State for its object to provide a pump for use in contracted space and in various places where the operation of a bulky mechanism would be impracticable, the arrangement of the pump being such that it may be operated by means of a cable connected with a source of power at a distance from the pump.

A further object is to provide a novel means for converting rotary motion into reciprocating motion for operation of the pump.

Other objects and advantages will be apparent from the following description, and it will be understood that modifications of the specific construction shown may be made, and any suitable materials may be used without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like characters of reference indicate similar parts in the several views, Figure 1 is a side elevation of the present pump connected with the operating mechanism. Fig. 2 is a longitudinal section of Fig. 1. Fig. 3 is a top plan view of the driving mechanism. Fig. 4cv is a section on line 4 4 of Fig. 1. Fig. 5 is a side elevation of a portion of the mechanism employed in connection with a different form of pump.

Referring now to the drawings, the present invention comprises a pump-cylinder 5, having the usual inlet and outlet valves 6 and 7 at its lower end and provided with a collar 8 at its upper end, from which extend a plurality of upwardly-converging rods 9, having a guide-block 10 secured to their upper ends.

Within the cylinder 5 there is disposed a piston 11, having a piston-rod 12, which extends upwardly out of the cylinder and is engaged in the guide-block 10, and disposed between the piston and the guide-block and encircling the piston-rod 12 is a helical spring 13, which holds the piston normally at the lower limit .of its motion.

The pump-operating mechanism consists of asupporting-frame 14,in which there is mounted in brackets 15 a slidable shaft 16, with the outer end 17 of which the upper end of the piston-rod 12 is connected by means of a cable 18. Secured to the frame M and extending at right angles to the shaft 16 is a circular yoke 19, which is spaced somewhat from the inner end of the shaft, and journaled in bearings 20 on this yoke is a shaft 21, extending in a plane parallel to that occupied by the yoke and having a pinion 22 upon its inner end which lies above the inclosure of the yoke. Disposed within the yoke and extending beyond the upper and lower sides thereof is a' pitman 23, and pivoted at its upper end to the upper end of the pitman there is an elongated yoke 26, having an inwardly-extending flange 27 at its rearward edge. Extending from end to end of the yoke there is a plate which carries a plurality of forwardly extending spaced pins 24:, these pins being connected at their outer ends by a plate 25. The pinion 22 lies in engagementwith these pins between the plates 25 and 25 and rests against the flange 27. Rotation of the shaft 21 results in reciprocation of the pitman, as will be readily understood, the pins lying at opposite sides of the pinion 22 during the upward and downward movement of the pitman. The pinion 22 is provided with a cylindrical boss 28 upon one of its sides, against which the edges of the plate 25 rest as the yoke moves. Depending from the lower end of the yoke 26 is a plate 29, which extends transversely and which is provided with a slot 30, as shown, and lying in this slot is a pin 31, carried by the pitman 23, and at either side of this pin there extends from the pitman a wing 32,

these wings lying against the plate 29 to pre-- vent twisting of the pitman.

The pitman 23 is provided with a cylindrical extension 33, which is pivoted to a collar 34, slidably engaged with the shaft 16, and disposed between this collar and spaced flanges 35 upon the shaft, which lies at either side of the collar, are helical springs 36, which surround the shaft 16. It will thus be apparent that rotation of the shaft 21 causes reciprocation of the pitman 23, as mentioned above, slight lateral movement of the pitman being permitted by its pivotal connection with the collar 3 1, this lateral movement being limited by the slot and the pin 31, as will be readily understood. Reciprocation of the pitman 23 results in similar movement of the shaft 16, the springs 36 taking up all jar caused by the operation of the mechanism.

Movement of the shaft 16 in one direction causes outward movement of the piston 11 and piston-rod 12, which compresses the spring 13, and this spring returns the piston and piston-rods to their normal positions when the shaft 16 is moved in the opposite direction.

This pump is especially adapted for use in mines or in wells during excavating, as it may be readily moved from place to place, and, be ing driven by mechanism disposed at a distance, may be successfully operated in small space.

In Fig. 5 there is shown a construction in which the shaft 16 is omitted and the collar 34 is engaged with the piston-rod a of a plurality of alining cylinders b, the spring 36 of the flanges 35 being provided, as described above. This arrangement is especially adapted for city waterworks, means for reciproeating the pitman 23 being capable of producing a large amount of power and the arrangement of the cylinders occupying little space.

What-is claimed is 1. A pumping mechanism comprising a plurality of cylinders, pistons disposed within the cylinders, a shaft slidably engaged in the cylinders and connected with the pistons for reciprocation of the latter when the shaft is reciprocated, brackets in which the shaft is slidably engaged, collars carried by the shaft, a pitman extending parallel to the shaft and having an eye in which the shaft is slidably end opposite to the eye, a plate extending longitudinally of the yoke centrally thereof, spaced rack-pins carried by the plate, a powershaft disposed at one end within the inclosure of the yoke, a pinion carried by this powershaft and meshed with the rack-pins, a plate carried by the yoke at its free end and having a slot therein extending transversely of the yoke, a pin carried by the pitman and engaged in the slot for movement longitudinally thereof, andlaterally-extending wings carried by the pitman and resting against the plate to prevent twisting of the pitman with respect to the yoke.

2. The combination with a pump, of means connected therewith for o eration thereof, said means comprising a slidably-mounted rod, a pitman pivotally connected with the rod, a yoke pivoted to the pitman a plurality of rackpins carried by the yoke, a revolubly-mounted power-shaft, a pinion carried by the powershaft and meshing with the pins, a plate having an arc-shaped slot carried by the yoke, a pin carried by the pitman and engaged in the slot, and laterally-extending wings carried by the pitman and lying against the slotted plate to prevent twisting of the pitman with respect to the yoke.

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

SOLOMON S. WHIPPS.
