ROTARY ENGIN E.
SPECIFICATION forming part of Letters Patent No. 674,716, dated May 21, 1901. Application filed February 1, 1901. Serial No. 45,558. (No model.)
To all whom it may concern:
Be it known that I, MARTINUs VAN GEL- DER, a subject of the Queen of the Netherlands, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Rotary Engines, of which the following is a specification.
My invention consists of a rotary engine having novel features, as will be hereinafter pointed out in the claims.
Figure 1 represents a vertical section of a rotary engine embodying my invention. Fig. 2 represents a transverse section thereof on line a; 00, Fig. 1.
Similar letters of reference indicate corresponding parts in the figures.
Referring to the drawings, A designates the cylinder or casing of the engine, and B the base thereof. On said cylinder, at the center thereof, are bearings O for the shaft D, and on the periphery thereof are the steamsupply port E and the exhaust-port F.
G designates the pistons, each consisting, as follows, of a body portion H, having a fixed rim J projecting rearwardly therefrom and forming chambers which primarily receive the steam, the latter being impacted against the faces of the cylinders, which faces are serrated to form depressions or valleys K therein, whereby increased pressure by concentration of the steam within said depressions or valleys by the angles of said serrations is obtained. The rear portions of the pistons are provided with inclined sides or cones L to decrease the resistance of the passage of the pistons. The relative dimensions of said pistons and the serrations are exaggerated in the drawings for the purpose of illustration, whereas in practice they would be considerably smaller.
While the operation of the engine is similar to that of rotary engines of this class, the present construction, however, increases the speed and power due to the chambers which primarily receive the steam and the concenv tration of the steam in the valleys or depressions. The steam, furthermore, cannot pass so quickly to the edges of the piston, so that I am enabled to dispense with the usual packing and cause the engine to run smoother and with less friction, since said rim is fixed or immovable on the body portion of the piston and is continuous around the same, whereby the pressure of steam is uniform on the face of the piston and initially confined within said rim and packing is dispensed with, as has been stated.
Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is
1. In a rotary engine, a piston having an immovable rim thereon forming a chamber at the front of said piston.
2. A piston for a rotary engine having an immovable rim, the same projecting forwardly from the front face of the body portion of the piston and extending entirely around the same.
3. A rotary engine having a piston, serrations on the front face of said piston, and a rim projecting from said face forminga chamher in front of said serrations.
4. A rotary engine having a piston, serrations on the front face of said piston, a rim projecting from said face forming a chamber in front of said serrations, and a cone or equivalent at the back of the piston.
5. A rotary engine having a casing, inlet and exhaust ports thereon, a piston which is formed of a body, and a cone or equivalent, the latter being at the back of said body, and a projecting rim forming a chamber at the front of said piston.
6 A rotary engine having a casing, inlet and exhaust ports thereon, a plurality of pistons, each formed of a body, a cone or equivalent at the back of said body, a projecting rim forming a chamber at the front of said piston, and braces connected with said bodies and cones or equivalents.
MARTINUS VAN GELDER.
