Description
HENRY AUSTIN HEWEY, OF CLAREMONT, NEW HAMPSHIRE.
ROTARY ENGINE.
Specification of Letters Patent.
Patented Nov. 57 1907'.
Application tiled April 23, 1906. Serial No. 313.264"
To all whom 'it may concern:
Ie it known that I, HENRY AUSTIN HEwEY, a citizen oi the United States, residing at Claremont, county of Sullivan, and State of New Hampshire, have invented a new and simple Rotary Steam or Compressed- Air Engine, of which the following is a specification.
My invention relates te rotary engines and its object is to provide a construction which is particularly sirnple and is highly ell'reient in use.
The invention includes the combination and arrangement of parts to be hereinafter described and particularly pointed out in the claims.
In the accompanying drawings, which illustrate one embodiment of the invention, Figure I is an end elevation of the engine with one head of the cylinder removed. Fig. 2 is a cross sectional view7 the pistons being shown in elevation, and Fig. 3 is a detail section view of one of the pistons.
The cylinder' includes heads of any suitable construction, preferably being provided with bearings for the power shaft, and a body or cylindrical part of novel construction to be hereinafter described in detail.
The power shaft has a suitable hub or abutment designated Il, secured thereto which is eccentrically mounted in the cylinder with its ends in steam tight contact with the said heads and its periphery running in Contact with the inner periphery of the cylinder at a point substantially in the line of a vertical plane intersecting the longitudinal axis of the power shaft. A crescent shape steam space is formed in the cylinder between the periphery of the abutment and the inner cylinder' wall.
The piston blades are designated D, are oppositely disposed to each other and are suitably connected to move radially of the hub in unison or as one part and are guided in their radial movement in suitable slots or recesses oppositely located in the hub D. The pistion blades are connected to each other by a coupling rod (l guided centrally of its length in openings provided through thehub in register with said recesses and through the power shaft. The outer ends of the.
coupling rod are preferably adjustably connected to the pistons so that the latter may be shifted to compensate for wear either of their endsyor ol' the inner periplrer'y of the cylinder. The connection between the coupling rod and piston is preferably so constructed that the adjustment referred to may be obtained withorrt dismantling the engine. As shown herein, each piston is provided with a socket leading inwardly from its inner edge in which the end of the rod associated with the piston is fitted and a binding screw E is associated with each piston for binding the latter upon the rod to prevent relative movement of the two.
The screws E extend through the piston from one i radial edge of the same and the heads of the screws are designed to register, during the travel ofthe pistons with au opening provided in one head of the cylinder casing. This opening is'normally closed by a suitable removable plug and is of such size that a tool may be inserted therein, after .the removal of the plug, for tightening up or loosening the screws. A spring I is located in each socket which bears at one end upon the end wall of the latter and its other end upon the adjacent end of the coupling rod. These springs serve to force the pistons into contact with the wall of the cylinder when the screws are loosened. Thus, in order to adjust the pistons to compensate for wear, it is only necessary to loosen the screw of one of the pistons Whereupon the spring associated therewith will immediately force the outer edge of the same into intimate contact with the opposing wall of the cylinder and thereupon the binding screw may be immediately re-tightened.
As before premised, the cylinder is of novel construction, the upper part thereof being formed on an are struck from the center .I which is located below the center of the hub. This are intersects the periphery of the lnrb at the point a, which is located in the vertical plane of the axis of the hub, and terminates in the horizontal plane of the axis of the head at the points designated g-c which are separated from each other a distance equal to that desiredbetween the outer edges of the pistons. The remaining part of the cylinder is formed of an arc struck from the point K which is located above the point J. The latter are intersects the points o o and a point below the hub B designated e in the vertical plane of the axis of the lnrb and separated from the point a a distance equal to that desired between the orrter edges of the piston. This construction provides a cylinderjall of whose diameters, intersecting the center of the hub, are of the same lengths as indicated by the letters h d, b-f.
The inlet and exhaust ports are designated H, are arranged in one of the heads of the cylinder and are of general arcuate elongated shape, the side walls of which converge toward the point a or toward the ends of the crescent shape steam space.
I claim:
1. In a rotary engine a cylinder, a power' shaft, a hub, pistons movable radially in the hub euch provided with a socket, a coupling bar having its ends fitted to said sockets and binding screws for rigidly connectingl the pistons lo the coupling hars.
2. In :r rotary engine a cylinder having an opening' through one head thereof normally closed, a power shaft. a huh, pistons movable radially in the hub each provided with a socket, a coupling bar having its ends fitted to said sockets. a binding screw associated with each piston extendingr through the same from one radial edge thereof,
the heads of said binding screws being designed to be sociated with each piston for rigidly connecting the same registered with said opening in the travel of the pistons, and meansfor forcing the pistons outwardly when the Ascrews are loosened.
5 3. In a rotary engine, a cylinder, a power shaft, a hub, two pistons movable radially in the hub, each provided with a socket, a coupling bar having its ends tted to the sockets, a spring located in each socket normally under compression between the end Wall of the latter and the l() adjacent end of the coupling bar, and a binding screw asto the coupling rod.
In testimony that I claim the foregoing as my invention I have hereto aflixed my signature in the presence ol.
witnesses.
