PUMP ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 232,143, dated September 14, 1880.

Application filed June 12, 1880.

To all whom. it may concern:

Be it known that I, IsAAo H. PALMER, of Lodi, in the county of Columbia and State of Wisconsin, have invented a new and valuable Improvement in WVindmill Pump Attachments; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making a part of this specification, and to the letters and figures of reference marked thereon.

The drawing is a representation of an elevation of my improved pump, partly in section.

Thisinvention has relation to improvements in windmillpump attachments.

The object of the invention is, in pumps operated by wind-en glues, to devise means whereby they may be worked by hand without, in the upstroke of the piston-rod of the pumps, having to raise the superineumbent weight of the mill-plunger and its connections when the wind fails.

The nature of the invention will be hereinafter more fully set forth.

In the annexed drawing, the letter A desig nates the pump-cover, B the pump, and C the frame, through which reciprocates the plunger I) in suitable guides on b.

D indicates the piston-rod of the pump, connected to the lower end of the plunger, reciprocated bythe wind-engine through the medium of the knee-jointed connecting-rods Gr G, pivoted to vibrate in the same plane respectively to the said piston-rod and to the plunger, and connected to each other by a rule' or other joint in such manner that while they will freely flex in one direction they are practically rigid as regards bending in theother.

It is evident that the reciprocation of the plunger will work the pump.

H indicates a rocking standard pivoted to an offset, 0, of the top of the pump, and afford ing a fulcrum to the handle-lever I in its upper end. This lever is of equal weight at each side of its fulcrum, and its weight end is pivoted to a projecting lug or arm, 11, extending outward from the rod Gr slightly above its connection to the piston-rod of the pump.

(No model.)

The lever I being evenly balanced on the standard H, no appreciable additional power is required to carry it when the wind-engine is at work.

Instead of the oscillating standard I may use a fixed one by connecting the weight end of the lever I to the lug (l on rod Gr.

Should the wind fail the pump may be worked by operating the lever I, when its weight end purchases upon the lug d and flexes and straightens the rods G G, thus actuating the pump-piston without raising the plunger.

I am aware that oscillating standards for the levers of hand-pumps have been used before; hence I do not claim this feature broadly.

As the pump-piston in this description of pumps must have some play, the diameter of the hole in the cap must be made considerably greater than that of the said rod, and I prevent bugs and insects from getting into the pump by means of a washer, a, resting loosely on the pump-cap and encircling the piston-rod. This washer is of greater diameter than the hole in the cap, and follows the piston during its play, at all times covering the said hole.

WVhat I claim as new, and desire to secure by Letters Patent, is-

1. In a pump operated by a wind-engine, the combination, with the piston D and the reciprocating mill plunger D, of the knee.- jointed connecting-rods G G and a pump-handle fulcrumed on the pump and connected to the rod Gr, substantially as specified.

2. The combination, with a pump-piston rod and a reciprocating plunger, D, of the kneejointed rods G G, connecting said rod and plunger, the oscillating standard H upon the pump, and the lever I, fulcrumed on said standard and pivoted to an oflset, d, of the pump, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

ISAAC H. PALMER.
