PUMP-HANDLE.

SPECTEIOA'IIOIlv forming part of Letters Patent No. 503,990, dated August 29, 1893.

Application filed March 25, 1893.

To all whom/it may concern:

Be it known that I, CHARLES A. SELLON, a citizen of the United States, residing at Pike, in the county of Wyoming and State of New York, have invented a new and useful Pump- Handle, of which the following is a specification.

This invention relates to pump handles; and ithas for its object to provide animproved adjustable pump handle attachment contemplating certain improvements over my former patent, No. 476,082, granted May 31, 1892.

To this end the main and primary object of the present invention is to simplify the construction of pump handles of this character, while at the same time rendering the same quite as efcient in practical use.

With these and many other objects in view which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawings- Figure l is a side elevation ofapump and apump handie connected thereto, as contemplated by this invention. Fig. 2 is an enlarged detail in perspective of the pump handle attachment. Fig. 3 is a sectional View on the line oc-a' of Fig. 1. Fig. 4 is a detail plan view of the slotted guide arm.

Referring to the accompanying drawings, A.

represents a pump of ordinaryconstruction and operated by means of the ordinary vertically reciprocating pump rod B, and said pump A, carries at its upper end the off-standing slotted guide arm O, in Which moves the upper end of the swinging pipe-standard D. The pipe standard D, is preferably made of a suitable length of pipe and is pivoted at its lower end at d, to the base of the pump A, while to the upper end thereof is attached the forked or bifurcated bearing yoke E, which is designed to have a play in the slot of the arm C, and to form a support for the adjustable pump handle F. The adjustable pump handle F, terminates at one end in the sector adjusting head G', which is provided on its periphery, or in its arc, with a series of locking or adjustment notches H, and terminates at one extremity in the attaching loop I, which is Serial No. 467,546. (No model.)

pivotally connected to the pu mp rod B, on the pivot bolt The sector adjusting head Gr, of the pump handle is embraced by the bearing vyoke E, in which it works, and has working on each side thereof the opposite adjusting links J. tor center j, and are provided near their outer ends with the off-standing pivot pins K, which engage bearing perforations at the upper eX- tremities of the yokeE, thereby providing a pivotal support for the sector head inside of said yoke, and to the outer extremity of one of the links J is pivotally connected one end of the weighted latch bar L. The latch bar L, carries a weight Z, at its unpivoted extremity, and is adapted to be dropped into engagement with any one of the notches in the arc of the sector head, and the locking notch M, formed in the outer end of the other adjusting link, said Weight serving to hold the latch bar into engagement with such notches to secure the pump handle in any adjusted position.

From the foregoing it is thought that the construction and operation of the herein described improvements Will be apparent to those skilled in the art. To adjust the pump handle in order to regulate the length of the stroke, according to the option of the person using the same, it is simply necessary to lift the weighted latch bar out` of the notches which it engages, to move the adjusting links tothe desired point on the adjusting head, and to drop the weighted latch lever into engagement With the notches at that point.

Changes in the form, proportion and the minor details of construction as embraced Within the scope of the appended claims may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a pump handle, the combination of a swinging bearing standard having a bearing yoke at its upper end, an adjustable pump handle terminating at one end in asector head adapted to move in said bearing yoke and provided with adjustment notches in its periphery, adjusting links pivoted at one end to the body of the sector head and provided with 0E- standing pivot pins engaging perforations in The links J, arepivoted to the sect IOO the extremities of said bearing yoke one of said links being further provided with a notch at its outer end, and a latch bar pivoted to the other of said links and adapted to engage the notches of said head and the link notch, substantially as set forth.

2. In a pump handle, the combination with the swinging bearing standard, and a slotted guide therefor; of an adjustable pump handle terminating at one end in a sector head provided with a series of notches in its arc, opposite circularly adjustable links pivoted to the center of the sector and to the upper extremities of the bearing standard, one of CHARLES A. SELLON.
