HENRY O. HANSEN, OF OSIIKOSH, \VISOONSIN.

PUMP.

SPECIFICATION forming part of Letters Patent N 0. 581,719, dated May 4, 1897. Application filed November 10,1896. Serial No. 611,667. (No model.)

To all whom it may concern:

Be it known that I, HENRY O. HANSEN, a citizen of the United States, residing at Oshkosh, in the county of \Vinnebago and State of lVisconsin, have invented certain new and useful Improvements in Pumps; and Ido declare the following to be a full, clear, and exact description of the invention, such as will enable others'skilled in the art to which it appertains to make and use the same.

My invention has relation to improvements in pumps; and the object of the invention is to simplify the construction and increase the durability of the pump.

To these ends the novelty consists in the construction, combination, and arrangement of the same, as will be hereinafter more fully described, and particularly pointed out in the claim.

The figure in the drawing is a perspective view of my improved pump.

1 represents the usual cast-iron standard, having spout 2, and 3 represents the vertically-reciprocatin g piston-rod, the upper end of which is secured in a socket 4. on the lower end of the connecting-rod 5, extending up to a windmill or other motor. A strap 6 encompasses the rod 5, forming a guide therefor, being secured to the vertical projecting arms 7 7 of the bracket 8, encompassing the standard and adj ustably secured thereon by bolts 9 9 and 10.

12 represents the pumpdiandle, pivoted at its forward end to the rod 5 and fulcrumed in one of a series of holes 13 13 on a bolt 14, secured in the upper end of a lever 15, which extends downward between the parallel arms of the bracket 8, its lower end fulcrumed on a bolt 16, secured in the arms 17 17 of a clamp 18, adjustably secured by bolts 19 19 to the pump-standard 1. The same bolt 16 also engages the parallel ea-rs 2O 20 of the brace 21, which extends downward and outwardly at an angle to the standard, and its foot 22 is secured to the floor or platform by a lagscrew 23.

An important advantage of my construction is that the handle, which is mounted on the movable fulcrum secured in the clamp 18, can be adj usted'to any position with reference to the spout by simply loosening the clamp 18 and bracket 8.

Another advantage is that the entire strain is taken from the clamp 18 and transferred to the brace 21, and incidentally the fact that the handle is fulcrumed in the upper end of the lever 15 preserves a strictly vertical movement of the piston-rod, preventing wear and tear on the rod and the tendency to wear the stuffing-box gland oval, as is frequently the case in this class of pumps where the fulcrum of the handle is stationary.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, as such changes or modifications may be made as clearly fall within the scope of my invention without departing from the spirit thereof.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s-

The pump-standard 1, the piston-rod 3, wrtically reciprocating in said standard, the bracket 8 encompassing the upper end of the standard and adjustably secured thereto by the bolts 0 9 and formed with the integral vertical diverging arms '7 '7, a guide-strap 6 horizontally secured to the upper converging ends of said arms, and the extension 5 of the rod 3 passing through said guide-strap in combination with the horizontally adjustable clamp 18, the brace 21 having its upper bifurcated end encompassing the horizontal arms 17 17 of said clamp and pivoted thereto by the fulcrunrbolt 16, the vertical lever 15, having its lower end fulcrumed in said pivot-bolt l6, and the handle 12 fulcrumed on the bolt 14, secured in the upper end of the lever 15, and having its outer end pivoted in the lower end of the extension 5, substantially as shown and described.

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

HENRY O. HANSEN.
