Hnesdaie, in .the @may of wayne and State of Peniisylvania,` have invented a new l and useful Improvement in Rotary Pumps; "endl I" do hereby Adeclare that Athe following lis aV full and` enact .description thereof, reference `being had to the *accompanying drawings, makinga` part" of this "specification.` l i.

their `revolution to move through a portion of the chamber of the pump which `com- `municates directlywith the induction `open.
ing j. The object of this arrangement is to prevent the water from being broken and beat up intofoamby the rapid movement of the buckets,as would be the case' if the water passed from the induction aperture directly tothe buckets :-Whereas, the water. `in my improved `pump passes in an unbroken current from the induction opening directly into the mouth of the channel k, and follows after each bucket until the said current is struck and carried forward by the `next "bucket in succession, and discharged at the eduction aperture y'.
VVhat Iclaim as my invention and desire to secure by Letters Patent, is causing the buckets c, c, c, during a portion of their revolution t pass through an enclosed channel k, and during Athe remainder of their revolution to pass through the chamber which communicates directly with the central induction opening f, substantially in the `manner and for the purpose herein. set forth.
The above specification of my improvement in rotary pumps signed and witnessed this 27th day of December 1854. 4
