No. 23233.—31st July, 1907.—JOHN GILL, of Beechwood Mains, Murrayfield, Edinburgh, Scotland, Gentleman. Improvements in rotary motive-power engines, applicable also to rotary pumps, air or gas blowers, compressors, or exhausters, meters, and the like.

Claims.—(1.) A rotary motive-power engine, pump, or the like of the kind referred to, having several piston-drums and discs or annular plates fixed side by side on the same central shaft and adapted to rotate together as one drum in a single casing divided into compartments by the said discs or annular plates, substantially as described. (2.) A rotary motive-power engine, pump, or the like of the kind referred to, having several piston-drums and discs or annular plates bolted or otherwise fixed together side by side without a central shaft, and adapted to rotate together as one drum in a single casing divided into compartments by the said discs or annular plates, substantially as described. (3.) A rotary motive-power engine, pump, or the like of the kind referred to, provided with discs or annular plates between the piston-drums or at the ends thereof, the said discs or annular plates having radial grooves adapted to receive, guide, and support the sides of the piston-blades, substantially as described. (4.) A rotary motive-power engine, pump, or the like of the kind referred to, provided with discs or annular plates between the piston-drums or at the ends thereof, and having a casing provided with grooves for the said discs or annular plates to rotate in, substantially as described. (5.) A rotary motive-power engine, pump, or the like of the kind referred to, the single piston-drum of which is provided with a disc or annular plate at each end provided or not with grooves to receive, guide, and support the sides of the piston-blades, substantially as described with reference to Fig. 7 of the drawings. (6.) In a rotary motive-power engine, pump, or the like the internal surface of the casing of which is composed of two opposite concentric circular arcs and two opposite involute curves as described, a piston-blade of invariable length having one-half of each of its edges shaped to fit the part of the involute curve at one side of the casing, which has the shortest radius of curvature, and the other half shaped to fit the similar part of the involute curve at the other side of the casing, substantially as described with reference to Fig. 3 of the drawings. (7.) The device for drawing the approximately involute curves of the inner surfaces of the casing of a rotary motive-power engine, pump, or the like of the kind referred to, which device consists of a disc placed concentric with the piston-drum, an inextensible cord fixed at one end to a point on the circumference of the said disc and, after passing round said disc, is attached at the other end rotatably to the centre of the said disc, and a pencil or scriber placed in the bend of the cord, substantially as described.

(Specification, 12s.; drawing, ls.)

as set forth. (2.) The use in a local anaesthetic compound of an aqueous solution of cocaine and of other ingredients, with adnephrin and listerine, substantially as set forth.
