ROTARY MOTOR.
SPECIFICATION forming part of Letters Iatent N0. 770,712, dated September 20, 1904.
Application filed y 29, 1904. Serial No. 218,741. (No model.) A
To a w/wm it may concern:
Be it known that I, LEVI SCRADDOOK, a citizen of the United States, residing at Talladega, in the county of Talladega and State of Alabama, have invented new and useful Improvements in Rotary Motors, of which the following is a specification.
My invention'relates to rotary motors, and has for its object a motor whichshall be simple in construction and efficient in operation.
With this object in view the invention consists in a novel arrangement of swinging pistons and other features hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a central vertical section of the motor, and Fig. 2 is a transverse section on the line 2 2 of Fig. 1. Fig, 3 is an edge view of the wheel which carries the swinging pistons. Fig. 4 is a detail.
Referring specifically to the drawings, 5 denotes a cylinder which is mounted on a suitable base 6. The cylinder comprises a rim 7 to which disks or plates 8 are bolted on each side. The disks are provided with a bearing for a shaft 9, which extends through the cylinder and to which the wheel 10 is keyed or otherwise fastened. The said wheel comprises a hub 11 and spokes 12 extending therefrom to a rim 13. In the face of said rim a number of recesses 14 are made, which receive the swinging pistons 15. Said pistons are hinged by a pin 16 between disks 17, bolted to the rim on both sides thereof. The water or other motive fluid enters the cylinder through a passage 18in the rim 7 which passage is tangential to the wheel. The discharge or exhaust is substantially diametrically opposite to the inlet through a port 19 in the rim 7. Behind the inlet an abutment 20 is formed. The curve of said abutment passes gradually into the curve of the cylinder, so that the pistons when they come in contact therewith will be gradually closed. A recess 21 is made in the abutment, in which recess a wing or gate 22 is hinged. The under side of the wing is curved to conform to the curvature of the abutment, and it fits snugly on the rim 13. The object of this wing is to prevent back pressure on the pistons. The tip of the wing extends slightly beyond the end of the abutment and into the path of the water, whereby it is pressed down against the rim 13, forming a tight joint.
In order that the pistons 15 may open rapidly when they are opposite the inlet, a small channel 23 is made in the tip of the wing. Similar channels 2 1 are made through the rim 13 and extend into the recesses 14 and under the pistons, which have on their under sides a recess 25 in line with the channels 24:. When the pistons reach the position shown in Fig. 4, the water flowing through the channels 23 and 24 and into the recess under the pistons causes them to swing outwardly at once to receive the full pressure of the water. To guide the movement of the pistons, they have at their inner ends a lug 26, fitting in an enlargement 27, made in the recesses 14:.
In the operation of the motor steam may be used instead of Water, in which case suitable packings will be provided.
Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is
1. A rotary motor comprising a cylinder containing a wheel having recesses in its rim, pistons hinged in said recesses, an abutment, a pressure-actuated wing, hinged to the abutment and in contact with the rim of the wheel, a fluid-inlet and adischarge-port, and channels from the fluid-inlet into the recesses behind the pistons.
2. A rotary motor comprising a cylinder containing a wheel having recesses in its rim, pistons hinged in said recesses, an abutment, a pressure-actuated wing hinged to theabutment and in contact with the rim of the wheel, a fluid-inlet and a discharge-port, and channels from the fluid-inlet through the wing and the rim into the recesses behind the pistons.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
LEVI S. ORADDOCK.
