PROPELLER.
APPLICATION FILED 0012511910.
1,000,030. Patented Aug. 8, 1911.
W/YZVESSES [1V1 'EXTOR WILLIAM JOHN MASON, OF SEATTLE, WASHINGTON.
PROPELLER.
Specification of Letters Patent.
Patented Aug. 8, 1911.
Application filed October 5, 1910. Serial No. 585,428.
To all whom it may concern:
Be it known that 1, WILLIAM J. Mason, a citizen of the United States, residing at Seattle, in the count of King and State of Washington, have invented certain new and useful Improvements in Propellers, of which the following is a specification.
This invention relates to screw propellers designed more particularly for aerial work,
and it has for its object to provide a novel method of driving an ordinary propeller whereby its light, swift thrust is changed to a strongerthrust.
In order that the invention may be better understood, reference is had to the accompanying drawing forming a part of this specification, and in which drawing an elevation of the invention is shown.
Referring specifically to the drawing, 1 denotes the propeller, the same being of ordinary construction, and comprising radial blades extending from a hub 2. The propeller shaft 3 is operatively connectedto a suitable drive motor which, in the present instance,'is an internal-combustion engine 4. It will be understood, of course, that any other suitable motor may be provided for driving the propeller. The propeller shaft is squared so that the ropellermay rotate therewith, and also be ree to slide back and forth thereon,
The propeller hub 2 has an extension 5 on one side which is formed with collars 6. Between these collars, the hub extension is loosely encircled by a yoke 7, and between said yoke and the collar 6 which is nearest to the propeller blades, is interposed a spring 8, said spring being coiled around the hub extension.
On the propeller shaft 3 is mounted, so as to turn therewith, a bevel gear 9, and in mesh with said gear are bevel gears 10, which latter are located on opposite sides of the propeller shaft. To the gears 10 are fitted crank pins 11 which are connected by pitmen 12 to opposite sides of the yoke 7. Inasmuch as the yoke is confined between the collars 6, it will be seen that when the propeller shaft is in motion, the propeller is given a reciprocatory movement on its shaft through the gears 9 and 10, and the pitmen 12. The propeller, therefore, has a combined movement, it rotating with the shaft and also reciprocating thereon, whereby a greater efficiency is obtained. The spring 8 allows more play and time to check the forward thrust of the yoke 7.
As before stated, the propeller is intended more particularly for aerial work, the reciprocatory movement especially adapting the propeller for such work. The action is similar to that of a hammer delivering a blow, the propeller in this case being the hammer and obtaining a support for delivering its blows, from the air. These blows are taken up by the frame of the machine, thus assisting in its propulsion.
The drawing does not illustrate the supports for the engine, nor the shaft, as the same form no part of the present invention. The parts may be supported in any suitable manner, a description of which is deemed unnecessary.
I claim:
1. The combination with a propeller, of a shaft on which said propeller is mounted for rotary and reciprocato movement, a hub extension on the propel er, a yoke connected to said hub extension, a bevel gear on the propeller shaft, bevel gears meshing with said gear, crank pins on the secondinentioned bevel gears, and pitman connections between the crank pins and the yoke.
2. The combination wlth a propeller, of a shaft on which said propeller is mounted for rotary and reciprocatory movement, a hub extension on the propeller, said hub extension having spaced collars, a yoke loosely fitted to the hub extension between the collars, a spring interposed between the yoke and the collar which is nearest the propeller blades, a bevel gear on the propeller shaft, bevel gears meshing with said gear, crank pins on the second-mentioned bevel gears, and pitman connections between the crank pins and the yoke.
In testimony whereof I aflix my signature in presence of two witnesses.
WILLIAM JOHN MASON.
