0. 0. KN AUSS & J. E. KRAUSE. ROTARY ENGINE OR PUMP Patented May 1, 1894.-
INVENTOHJ' UNITE -TATES ATENT FFICE CHARLES C. KNAIISS AND JAMES E. KRAUSE, OF BETHLEHEM,
. PENNSYLVANIA.
ROTARY ENGINE OR PUMP.
SPECIFICATION forming part of Letters Patent No. 519,156, dated May l, 1894.
I Application filed September 12, 1893- Serial No. 485,324. (No model.)
the blades anddetermine their radial movement, difficulty is frequently encountered owing to scale or other extraneous matter getting into the cylinder and encountering the blades with the result of stopping the engine. To meet this difficulty we construct each bladeof two parts with an intermediate yield- 1ng spring. e
In the accompanying drawings Figure 1 is a plan or end View of a rotary engine provided with our improvement, the head of the cylinder being removed. Fig. 2 is a vertical section, and Fig. 3 is a perspective view of one of the blades.
Our improvement may be applied to various constructions of engines or pumps, and it will therefore be understood that while we describe our inventionin connection with or as applied to one form of engine, we do not confine ourselves thereto. I In these drawings, A is the cylinder of oval or eccentric cross-section and within this is mounted to turn the rotary drum B, provided with suitable radial slots 1) for the reception of the sliding blades. I Fixed to the two heads ranged to occupy spaces within the recessed ends of the drum and to act upon the edges of the blades.
As will be seen more clearly on reference to Figs. 2 and 3, each blade E is made in two parts 6 e of substantially the same thickness andone part arranged in linewiththeother; one part forms in effect a continuation of the back other, and between the two is arranged an elliptic spring S such that when the two-part blade is in place and the cams are acting on one part, while the opposite edge of the other part bears againstthe interior of the cylinder, the outer part can yield in the radial direction to let any scale or other obstruction which happens to get into the cylinder pass.
The danger of stoppage of the enginetis To guide the two parts ness in line with each other, and one having 1 cars 3, 3, adapted to notches in the other, an elliptic spring, S, between the said ears and acting to press one part of the blade against the cams, and the other against the interior of the cylinder, all substantially as and for the purpose set forth.
In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses. I
