UNITED STATES PATENT FEICE.

NIKOLAS HOTZ, OF BROOKLYN, NEV YORK.

v||vn=aovEMENT IN PUMPS.v

Specification forming part of Letters Patent No. 46,360, dated February 14, 1865.

To all whom it may concern:

Be it known that I, NIKoLAs Horz, of Brooklyn, inthe county of Kings, in the State of New York, have invented certain new and useful- Improvements in Pumps; and I do hereby declare that the following is a full and exact description thereof'. The accompanying drawing forms a part of this specification and is a central vertical section through pump containing my improvements.

To enable others skilled in the art to make and use :my invention, I will proceed to describe it by the aid of the drawing and of the letters of reference marked thereon.

A is a smoothly-bored cylinder or barrel, and A A2 are rough extensions thereof.

A3 is the top plate, A4 is the bottom plate, A5 is the suction-pipe, and AG the`deliverypipe. The suction and delivery A es may either or both be provided with a..l essels and other ordinary devices, as check-valves for some purposes, if desired.

A7 is a smoothly-bored tube or pipe extending downward from the center ofthe top plate, A,

ward from the bottom plate, A4.

A9 is a frame adapted to support the center of motion of the operating-lever. These parts constitute the lixed portion of my machine.

B B2, are boxes or valved buckets with valves opening upward, and b b2 are rods firmly fixed therein, the rod b extending upward from the bucket B', and the rod b2 extending downward from the bucket B2.

C C2 are rods adapted to slide vertically through the guides D D. An arm keyed on the rod C is indicated by c', and to this arm the rod b is attached. A corresponding arm, c2, is carried on the rod C2, but at the lower end, instead of the upper end thereof, and to the arm c2 the rod b2 is attached.

M is a hand-lever adapted to `turn on the fixed center m above the pump supported as above' described.

N and N 2 are links connecting the lever M to the sliding rods C C2 by joints or eyes l 1 and 2 2, as represented, so that the vibrations of the hand-lever lVI will operate the buckets B B2 simultaneously in opposite directions A8 is a corresponding tube extending up and cause the water to dow upward through the barrel in an almost uninterrupted current, as will be obvious.

Pumps having two valved boxes corresponding in motion and function to my boxes A and B, have been before known and apabove and below tting on threads. (Not represented.)

J is a corresponding double cup-leather similarly lixed on the rod b2. As the pump is operating, these double cup-leathers traverse up'and down in the smooth pipes or tubes A7 A, the upper leather in the suction-box expanding and fitting tightly to the tube A7 on its ascending motion, and the lower leather expanding and fitting tightly in the descending motion. The double cup-leather in the lower box performs a corresponding duty. These suction-boxes allowv an easy mot-ion and tight ht. They are very durable and are very readily and cheaply repaired when necessary.

I have used my pump successfully in situations where ordinary pumps could not serve. For example, I have pumped very thick material, nearly as thick as paste, and the same pump has been successful in pumping air. No other pump known to me can serve so wide a range of purposes and be equally simple and portable. I have made my cylinder A and the extensions A A? of sheetcopper and have packed my valve-boxes B B2 loosely with simple cup-leather, as indicated, and iind that the pump, although extremely light and obviously liable to beindented, answers well with careful usage. I attribute the success of my pump in working very ethereal fluid to the rapidity with which it may be easily operated, and its sucsecure by Letters Patent, is as follows:

cess in working very thick mud. to the fact hand-lever M and the two movable valvethat the uifl or semi-Huid. is not allowed to boxes `B B2, all arranged and operating torest at all in its motion through the pump. gether as herein set forth.

Havin(r now fully described my invention 1 r what I elbaim as new in pumps, and desire to NIKGLAS HOT' Witnesses:
