ROTARY ENGINE.
Speeication of Letters Patent.
Patented June 27, 1911.
vApplication filed November 30, 1910. Serial No. 594,946.
To all whom it 'may concern:
Be it known that I, OnvrLLn G. McMiL- LAN, citizen of the United States, residing at Brookings, in the county of Brookings and State of South Dakota, have invented certain new and useful Improvements in Rotary Engines, of which the following is a specification.
rlhis invention relates to rotary engines, and one of the principal objects of the same is to provide a rotary engine of simple construction which will operate smoothly and develop a high rate of speed and considerable power with a comparatively small expenditure of steam or other motive element.
Another object of the invention is to provide means for admitting steam to the cylinder at suitable intervals and providing a cut-off which is automatically operated to cut-off the power after a suitable charge has been admitted to the cylinder.
These and other objects may be attained by means of the construction illustrated in the accompanying drawing in which,
Figure 1, is a vertical sectional view taken on the line 1-1 of Fig. 2, looking in the direction indicated by the arrow, portions being broken away and shown in section to better illustrate the construction of the various parts. Fig. 2, is a plan view of the same, portions being broken away and shown in section.
Referring to the drawing, the numeral 1, designates the base or framework of the rotary engine which is provided with a cylinder 2, which may be integral as shown or connected to the frame and supported thereon. The frame has an integral projecting portion 3, for a purpose which will presently appear. A shaft 4, extends through the cylinder 2, and keyed near the opposite ends of said shaft are wheels 5, each provided with a cam groove 6, upon its inner side. A belt pulley '7, is secured to one end of said shaft.
Rigidly connected to the shaft 4:, inside the cylinder 2, is a drum 8, provided with a piston member 9, which extends from the drum and bears against the inner surface of the cylinder 2, from end to end. Extending into the projecting portion 3 of the frame is an intake pipe 10, which leads from any suitable source of power to a recess 11, in the frame portion 3. The cylinder 2 is provided with an inlet port 12, which communicates with the recess 11. A sliding cut-0E 13, is mounted in the recess 11, said cut-off being provided with a stem 141, extending through a stufling box 15, connected to the frame. A guideway 16, formed in a recess 17, in the frame serves to guide a sliding block 18 to which is pivotally connected at 19 the outer ends of a pair of arms 20, and said arms are provided with eccentric members 21, mounted on the shaft t.
A sliding abutment 22 extends into the cylinder 2, and bears upon the outer surface of the drum 8, in one of its positions. Connected to the abutment 22, is a member 23, provided upon its opposite ends with rollers 24, mounted in the cam grooves 6. A shank 25, connected to the abutment extends through a stuffing box 26, and is provided with a slide 27, mounted to slide in a guideway 28, formed in a recess in the projecting portion 3 of the frame. An exhaust port 29, is connected to the cylinder 2.
The operation of my rotary engine may be briefly described as follows The sliding abutment 22, is withdrawn from the path of the piston 9, when the projecting portion a of the cani groove 6 moves the rollers 24: outward, and this movement is timed to occur as the piston 9 approaches said abutment. After the piston 9, has passed the inlet port 12, the abutment 22 is quickly returned to its original position and the sliding cut-o 13 is moved to admit a charge of steam or other motive force into the cylinder 2, between the abutment 22 and the piston 9, said charge serving to rotate the piston until after it passes the exhaust port 29. This cycle of movements is continuous during the rotations of the piston. It will be obvious that the cut-off valve may be operated to suit any cycle of movements requiring an excessive amount of power or increase of speed. It will be understood that the piston is rotated in the direction of the arrow shown in Fig. 1.
From the foregoing it will be obvious that my rotary engine is of simple construction, is composed of few parts which cannot readily get out of order, and that the engine can be maintained for a comparatively small amount of steam or other motive power.
I claim 1. A rotary engine comprising a cylinder, a rotating piston in said cylinder, an inlet port, an exhaust port, a sliding cut-off for controlling the admission of the Vmotive power to said cylinder, said cut-off being provided with a shank extending through a stuiiing box, a slide connected to said shank, arms connected to said slide, a shaft extending throughthe cylinder, eccentrics for operating the cut off, said eccentrics being mounted on the sha-ft, an abutment, and cam Wheels for operating said abutment.
2. A rotary engine comprising a cylinder, a shaft mounted in the cylinder, a piston connected to the shaft, cam Wheels connected to said shaft, an inlet port and an exhaust port communicating With said cylinder, a
sliding abutment operated by the cam Wheels, a cutoff Valve for said inlet port, a shank connected to said valve, a slide connected to said shank, arms connected to said slide and eccentrics mounted on the shaft for operating said cut-off Valve.
In testimony whereof I affix my signature in presence of two Witnesses.
