PUMP ATTACHMENT.

To all whom it may concern: 7

Be it known that I, JOHNFRE a citizen of the United States, residing at Guide- Rock, in the county of Webster, State'of Nebraska, have invented certain new and useful Improvements in Pump Attachments;

and I do hereby. declare the following to be a full, clear, and exact description of the nozzle or be directed through a branch pipe and delivered at any desired point.

\Vith the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claims.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which- Figure 1 is a vertical longitudinal section of a portion of a pump having the attachment associated therewith, the pump plunger being shown at the limit of its down stroke and the three-way valve of the attachment set to effect the discharge of the water through the pump nozzle. Fig. 2 a view similar to Fig. 1 showing the pump plunger at the limit of its upstroke and the threeway valve of the attachment set so that the water will be discharged into a branch pipe. Fig. 3 a view in elevation of the attachment on an enlarged scale, and Fig. 4; a section on the line 4 t of Fig. 3.

Referring to the drawings 10 indicates the barrel of the pump which has a suitable section removed therefrom in its length and substituted for this section is the tubular member 11 of the attachment, said member Specification of Letters Patent.

Application filed December 9, 1912. Serial No. 735,757.

11 being secured to the adjacent ends of the resultant barrel sections by means ofiT-joints '12. Secured to the T-joints l2'respectively are the terminals of a branch pipe line 13 and disposedin this branch pipe line '13 is a three-Way valve 14 operated by a handle15 and serving to divert the water passing through the branch pipe line 12 to a pipe Iatented Nov. 2, 1915.

line 16. Mountedin the lower end of the pump barrel 10-is' the usual check valve 17- and sl1dable in the barrel 10 between the check valve 17 and the adjacent T-joint 12 is i the usual plunger 18 secured to one end of a plunger rod 19. This rod 19 extends upwardly and is connected at itsupper end to the usual pump operating handle (not shown). The plunger rod 19 includes a section 20 upon'which is mounted a cup plun ger 21 adapted for movement in the tubular 1 member 11.

By this construction it will be apparent that as the plunger rod 19 is reciprocated in l the usual manner the upstroke of the plun ger 18 will draw the water above vthe valve 17, while the down stroke of said plunger will close the valve 17 and force the water through the plunger 18 into the barrel 10 thereabove. Continued reciprocation of the plunger rod will cause the water to fill the entire space between the cupplunger 21 and the valve 17 so that upon each down stroke of the cup plunger 21 the water will be forced into the branch pipe 13 at the lowermost T-joint 12. If the valve 14. is set as shown in Fig; 1 the water will continue through the branch pipe 13 and be delivered to the barrel 10 and section 11 above the cup plunger 21 and finally discharged through the pump nozzle. If the valve 14 is set as shown in Fig. v2 the water will be diverted through the pipe 16 as will be obvious.

What I claim is In a pump, the combination of a pump barrel, a valved plunger movable in said bar= 'rel at points respectively above and below the limits of movement of the non-valved plunger and further having. its upper end In testimony whereof, I affix my signature, in the presence of two Witnesses.

communicating with the space in the barrel between the same and the non-valved plunger, a three-Way valvecontrolling c01n1nuni cation between the interior of the by-pass pipe and said discharge outlet, and a check valve in the lower end of the pump barrel beneath the valved plunger.
