PUMP ATTACHMENT.

Specification of Letters Patent.

Patented May 10, 1910.

Application filed May 24, 1909. Serial No. 498,084.

To all whom it may concern:

Be it known that I, O'rro NUERNBERGER, a citizen of the United States, residing at Comfort, Kerr county, Texas, have invented a new and useful Pump Attachment, of which the following is a specification.

My invention relates to pump operating attachments and particularly to that type which is adapted to be operated by a Windmill rod and also by a pump handle or a pump jack. Heretofore in devices of this character it has been necessary to disconnect the windmill when it was desired to use the pump jack or hand lever, for instance, when the windmill failed to operate for lack of power.

It is the object of this invention to obviate this difliculty and broadly speaking, consists in providing an attachment for pumps which may be operated by the windmill and independently by a pump jack or a hand lever without disconnection.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrange ment of parts, as will be more fully described and particularly pointed out in the appended claims.

In the accompanyino drawings, Figure 1 is a front elevation 0? the tubes with the windmill plunger broken away. Fig. 2 is a vertical section on the line 2-2 of Fig. 1. Fig. 3 is a detail plan view of the lower bracket.

Referring more especially to the drawings, 1 represents a pump tube or cylinder which extendsup from the ground 2 where it enters the well and mounted within the tube is a plunger rod 3 upon which the usual piston is carried. At intervals throughout the length of the pump cylinder, there is secured thereto a plurality of cross braces or brackets in detachable manner by means of the set screws 5 and mounted to slide in these brackets on either side of the pump cylinder, a pair of tubes 6 which have their upper ends threaded as at 7 to attachably receive the brace 9, held in position by the locking nuts 8. A similar brace 10 isadjustably secured adjacent to the lower ends of the tubes and is slidably mounted upon the cylinder 1. The cross brace 9 has a central aperture therethrough, which is engaged by the upper end of the pump plunger 3 and mounted on either side of the brace upon the plunger are spiral springs 11 and 12 which are adapted to absorb the shocks of direct movement upon the plunger so that the piston is moved within the cylinder gradually instead of with a sudden motion.

The windmill plunger or rod is shown at 13 and secured to its lower end is a cross head 14 which is adapted to support the operating rods 15 which pass through the head adjacent each end thereof and extend downwardly through the tubes 6. The lower end of the rods are provided with nuts 16 which retain spiral springs 1? in position thereon in such a manner when the rods are raised the springs will be compressed between suitable washers 18 which bear againstthe end of the tube and the nuts 16 so that the tubes are raised within the brackets at gradually instead of with a sudden movement.

The lowest bracket 4 is provided with a pair of bracket ears 19 between which is pivotally mounted the pivoting link of the hand lever 21. This lever 21 is provided with a hooked end 22 adapted to engage beneath bracket 10 which is adjustably secured to the tubes and slidably mounted upon the tube 1, in order that the tubes may be raised in the bracket 4 independently of the action of the windmill plunger 13. It will be no ticed that when the tubes are operated by the lever 21 they slide upon the rods 15 and carry with them the plunger 3 independently of any action of the windmill plunger 13. When the pump handle is not in use it is disconnected by removing the hooked portion 22. Under these conditions, the windmill may operate Without affecting the pump lever 21 or a pump either to the bracket 10 or to the cross head 9. It will be noticed that in the operation of the device, the wind mill rod should be in lowered position in order that the full stroke of the lever 21 may be obtained.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.

Having thus described my invention, what I claim is:

l. In combination with a pump cylinder,

jack may be connected connection between the pump plunger rod and the hollow members, a windmill plunger, means to resiliently connect the hollow members with the windmill plunger, and means to operate the hollow members and thereby the pump plunger rod independent of the windmill plunger.

Vitness, my hand, at Comfort, Texas, this the 19th day of May A. D. 1909.

OTTO NUERNBERGER.
