Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed August 12, 1913. Serial No. 784,343.

citizen of the United'States, residing in the city and'county-of San Francisco, State of California, and JONATHAN WARNER, a subject of Great Britain, and residing in said city and county and State, have invented certain new and useful Improvements in R0- tary Engines, whereof the following is a specification.

Our invention relates to gas engines in a general way and more particularly to gas engines of the rotary type and has for its object to simplify the construction of that class of machines, thereby reducing the cost of manufacture and increasing their efiiciency.

With the above purpose in view our invention consists in a stationary frame having a cylindrical chamber formed therein and provided with closed flat ends; an eccentrically curved inner surface, a movable cylinder hereinafter called a rotor carrying pistons expansible against said closed flat ends and eccentrically curved inner surface, cheeks expansible against the flat ends, in combination with compressing, mixing and firing means. v

It also consists in the novel parts. combinations and arrangements, set forth in the following description and particularly pointed out in the claims at the end'hereof.

For the purpose of explaining our invention we have in the accompanying two sheeth of drawings forming a part of this application illustrated the same in what we consider its best form.

In the drawings: Figure 1 is an elevation of a structure embodying our invention. Fig. 2 is a vertical sectional view taken along the dotted line a,'-a of Fig. 1. Fig. 3 is a view similar to Fig. l with one of the ends removed to show the inner mechanism. Fig. 4 is a central sectional view taken along the dotted line bb of Fig. 2. Fig. 5 is a plan view of the starting mechanism. Fig. 6 is an elevation of the starting mechanism. Figs. 7, 8 and 9 are detail views of the pistons carried by the rotor of the engine.

The same symbol of reference marks the same part in whichever view. said part may appear. K

Describing now our invention in detail it comprises primarily a stationary part and movable part called a rotor, along with which there go compression, mixing and firing means and various auxiliary devices. The stationary part as shown in Fig. 4 consists of a frame A, a cylindrical chamber therein having an eccentrically curved inner surface 2 and feet 3. It is also provided withan intake port 4, exhaust port 5 and a spring actuated block 6 for preventing backfiring. The rotor 7 is centrally mounted on the shaft 8 and consists of a wheel having annular checks 9 and 10, set in grooves about the sides near the periphery of the wheel, and expanded apart by springs 11 against the flat inner surfaces of the cylnder heads. The wheel carries recesses 12 1n its periphery in which work pistons 13 actuated by springs 14 to engage the curved face of chamber 1." Pistons 13 are provid ed wlth cheeks 15 and 15 as shown in Figs. 7 and 8, which are expanded against the fiat cylinder heads by springs 16.

Figs. 7, 8'and 9 are plan side and end elevat ons respectively of one piston and a plurahty of such pistons is used, three being shown in the drawing, to avoid the possibility of stopping on a dead point.

The intake pgrt 4 is located at a point where the curvature of the surface takes a sudderl'drop, so as to form a chamber 17 communicating with said intake port between the wall, the periphery of the wheel, and any piston. 13 lying ahead of said point. Back of the intake port a spring actuated block 6 works in a recess 18 in the stationary cylinder in sliding contact with the rotor, to prevent back firing.

Cams 19 and 20 are mounted onshaft 8. Cam 19 operates piston 21 througharm 22 said piston compressing and mixing-air and gasoline in the cylinder 23. Cam 20 operates valve 24 through arm 25 said valve controlling the admission of the explosive mixture to the cylinder 23. A firing plug 26 is inserted in substantially the position shown and operated by any well known means.

For starting our device we provide a hand lever 27 pivoted to the shell, and a second lever 28 also pivoted to the shell. A link 29 joins the two levers, and blocks 30 and 31 are fixed to said link. Pawls 32 and 33 are pivoted on arms 22 and 25 so as to engage blocks 30 and 31. Moving the hand lever moves the link 29 causing engagement be tween block and pawl 32 and between block 31 and pawl 33, thus moving the arms longitudinally after the manner in which the cams l9 and 20 move them. Moving the arms moves the compression, mixing valve and firing mechanism and so starts the engine Having thus described our invention and believing we have produced useful and novel improvements in the art to which the same appertains let it be understood that save do not wish to be limitedto the exact construction and arrangement of the several parts composing the same as many changes can be made without departing from the spirit thereof.

What we claim as new and desire to secure by United States Letters Patent is 1. In-a gas engine, a frame provided with a starting device comprising compression, valve and firing mechanism, a hand operated lever pivoted on said frame, a second lever also pivoted to said frame, said levers having a connecting link secured thereon; blocks secured to said link, longitudinally movable arms connected to said valve and compression mechanism,and pawls on said arms for engaging said blocks.

' 2. In a gas engine a stationary frame having a cylindrical chamber closed at the ends and provided with an eccentric inner curved face and an exhaust port, a centrally mounted-rotor having spring actuated pistons engaging said eccentric inner curved face, and provided with lateral actuateu oheeks engaging the inner surfacesof said ends, springs located in said pistons for actuating said cheeks, a compression cylinder having a piston, adapted to control an intake port to said cylindrical chamber, and means connected to the main shaft to operate said piston.

In testimony that we claim the foregoing we have hereto set our hands in the presence of two witnesses, this 7th day of Aug. 1913.
