GEORGE W. HERRVING, OF BANGOR, MAINE. Letters Patent No. 70,211, daad october 29, 1867.

IMPROVEMENT IN WATER-WHEELS.

TO ALIi WHOMIT MAY CONCERN:

` Be it known thatI, G. W. HERRING, of Bangor, in the county of Penobscot, and State of Maine, have invented a. new and improved Water-Wheel; and I do hereby declare that the following isa full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this specification.

This invention rela-tes to a new and improved centrevent water-wheel, and it consists in a peculiar construction and arrangement of the same, whereby the usual platform for the wheel to run upon is avoided, and

.the wheel rendered capable of running .in either direction, right or left, ,at the option of` the millwright. In

the accompanying sheet of drawings- ,Figure I is a vertical central section ot` my invention, taken in the line x x, iig. 2. Figure'2 a horizontal section of the same, taken in the line y y, fig. 1. Similar letters of reference indicate corresponding parts. A represents the scroll, in which the wheel B is fitted. This wheel is composed o' two annular plates or rims a a, placed one over the other, anld connected tothe shaft C by buckets b, which are of eurvedform, and

extend each from the exterior ofa shaft, C, with a. gradual curve, as shown at c, to nearly the outer edges of A the rims a a', from vwhich they extend radially to the edges of' the rims, as shown at d, (se tig.) These buckets 6 may bc termed the long buckets, for between them are shorter buckets, e, which are formed with radial portions,f, at the outer edges of the rims a a, the other portions being curvedyas shown at y, and extendingonly to the inner edge of the lower rim la. The bottom L of the scroll A has a circular opening made in it to receive the lower rim a of the wheel, as shown in dgl, and the water first acts b y impact :against the radial parts df of the buckets, and then reacts against the curved parts c g, and passes out through the opening at the centre of the lower rim a of the Wheel, which rim forms a portion of the bottom to hold up or sustain the water, tbe latter, in passing through the wheel, not coming in contact with any immovable surface, which has a tendency to create friction and detract from the effective force of the water.

This wheel may be set up to turn either to the right or left, as occasion may require; it will operate equally well in turning in either direction. The alternate long and short buckets a a are a great advantage, as a suffi;

.cient number of' buckets is obtained near the periphery 'of the wheel for the water to act against, and a free space allowed for the escape of the water at the centre of the wheel. I claim :1s-new, anddesire to secure by Letters Patenti The alternatev long and short buckets Zi e, formed respectively with curved and radial portions c g tlf, and` ',placed or arranged relatively with the upper and iower rims a a of the .wheel and the shaf't C, and the lower rim a fitted in a circular opening in the bottom of the scroll, substantially as herein shown and described.

GEORGE W. HERRING.
