AxEL EMIL ARONS, OF INTERNATIONAL FALLS, MINNESOTA.
ROTARY MOTOR.
Specification of Letters Patent.
Patented June 2, 1908.
Application filed September 19, 1907. Serial N 0. 393,649.
To all whom it may concern:
Be it known that I, AxEL EMIL ARoNs, a citizen of the United States, residing at International Falls, in the county of Itasca and State of Minnesota, have invented certain. new and useful Improvements in Rotary Motors, of which the following is a specification.
This invention is a rotary motor, and has for its object to provide a motor of im roved design characterized by a disk aving radially extending piston-blades which pass throug a chamber in which they receive the pressure of the motive fluid. Means are also provided for feathering the blades outside the chamber so as to reduce the resistance to their travel.
The invention also contemplates a novel closure for the pressure chamber which is automatically opened by the piston-blades,
In the accompanying drawing, Figure 1 is an elevation of the motor. Fig. 2 is a longitudinal sectional view. Fig. 3 is an end view. Fig. i is a cross section. Fig. 5 is a perspective view of one of the pistons. Fig, 6 is a sectional detail showing the closure for the pressure cylinder.
Referring specifically to the drawings, the motor-frame comprises spaced plates 10 and 11, respectively, and bearings 12 for a shaft 13. To the shaft, between the plates 10 and 11, is keyed or otherwise secured a disk 14 carrying radially extending piston-blades 15 which are made to feather about an axis coincident with the radius of the disk.
The piston-blades have stems 16 which are mounted in radial recesses in the disk. On the inner ends of the piston stems are laterally presented wings 17 and 18, res ectively arranged at right angles to each ot er, and adapted to alternately project from opposite sides of the disk, and to cooperate with cams to feather the piston-blades in a manner to be hereinafter described.
Between the blades 10 and 11, at the top thereof, is located a segmental chamber 19 through which the piston-blades travel. In the bottom of the chamber is a slot to admit the rim of the disk. The walls of the slot have a suitable packing 20. Near one end of the chamber is an inlet 21, and near the other end is an outlet 22 for the steam or other motive fluid which acts on the piston-blades during their travel through the chamber.
The outlet end of the chamber is open, and
the inlet end has a pair of inwardly swinging doors 23 the free ends of which meet midway between the side walls of the chamber so as to be in the path of the pistonblades. The doors are held normally closed by the pressure in the chamber which is assisted by springs 24 arranged between the doors and the side walls of the chamber. The top and bottom edges of the doors are provided with a suitable acking 25. The piston-blades are wedge-shaped, as clearly shown in Figs. 3 and 5, by reason of which they will automatically force the doors open when they enter therebetween. After the piston-blades clear the doors, they are closed by the springs 24 and the pressure in the chamber.
The piston-blades turn so that their faces are squarely presented to the pressure immediately after they clear the doors and pass the inlet 21. This turning movement of the piston-blades is effected by the engagement of the wings 17 with a cam surface 26 on the inside of the plate 10 in the path of said wings. The feathering of the piston-blades is effected by a cam surface 27 on the inside of the plate 11 in the path of the wings 18. IVhen the wings 17 come in contact with the cam 26, the stems 16 turn and thereby present the faces of the piston-blades to the pressure. At the same time, the wings 18 swing outwardly and project from the disk into the path of the cam 27, so that when they strike the same, the stem 16 will be turned in the opposite direction to feather the piston-blades. The cams 26 and 27 are so positioned that the first described movement of the piston-blades takes place imme- I diately after they clear the doors 23 and the inlet 21, and the feathering movement takes place just as soon as the piston-blades leave the pressure chamber 19. The extent of the cam 27 is such that the piston-blades will be held feathered during their entire travel outside of the pressure chamber.
By the parts herein described, a motor is had which is simple in construction and efficient in operation. piston-blades greatly reduces the resistance to their travel. All valve gearing is dispensed with and there are no complicated parts to get out of order. In case water is used as a motive fluid, the outlet or exhaust 22 may be dispensed with.
I claim 1. A rotary motor comprising a disk hav- The feathering of the I ing radially extending piston-blades, a pressure chamber through which the pistonblades travel and having inlets and outlets, means for feathering the blades outside the chamber, a closure for the end of the chamber adjacent the inlet, said closure comprising a pair of inwardly swinging normally closed doors engageable by the edges of the pistonblades to open, and means for turning the sides of the pistonb1ades to the pressure inside the chamber.
2. A rotary motor comprising a disk having radially extending wedge-shaped pistonblades, a pressure chamber through which the piston-blades travel and having inlets and outlets, means for feathering the blades outside the chamber, a closure for the end of the chamber adjacent the inlet, said closure comprising a pair of inwardly swinging normally closed doors engageable by the edges of the piston-blades to open, and means for turning the sides of the piston-blades to the pressure inside the chamber.
In testimony whereof I have aflixed my signature, in presence of two witnesses.
