Specification of Letters Patent.
Patented only 27, 1909.
Application filed August 1a, 1908. Serial No. 449,111.
.To all whom it may concern:
- Be it known that we, JOSEPH- WoLL and vADAM WoLL, citizens of the United States of v is of such a contour as to aid in this res ect,
America, residing at Duquesne, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Propellers, of which the following is a s ecifica-tion, reference being had therein to t e accompanying drawing.
This invention, relates to ropellers, and the object of our invention is to provide a novel propeller that will-be highly eflicient for driving bodies, as boats, air ships, aerial planes and vessels of various types. Our invention aims to provide a simple and inexpensive propeller having a low. resistance and a high degree ofpro elling power. The propeller is constructed wliereby the air or water will be deflected in adirect line with the body being propelled, and in an opposite direction. Each blade of the propeller the assemblage of the blades being suc as to provide a positive cooperation between all of the blades, as a driving medium.
The detail construction entering into our invention will be presently described and then s ecifically claimed.
In t e drawings :Figure 1 is a side elevation of our propel1er','and Fig. 2 is an end nates a shaft adapted to be driven b view of the same. 7
In the accompanying drawings, 1,-desigour propeller. Mounted upon the shaft is 'a hub 2 having four right angularly dis osed triangular blades 3, eachblade in p an corre sponding to an isosceles triangle or two right angular triangles having a common altitude 01' perpendicular.
Considering each blade as two right angular triangles, with their bases at the hub 2,
.the hypotenuses 4 and 5 of said triangles are provided with auxilia auxiliary blades 6 an 7 are rectangular in blades 6 and 7. The
plan, and are dis osed at right angles to the ypotenuse 4 an ,5. The auxiliary blade 6 is arranged at one side ofthe blade 3 and the auxiliary blade 7 at the opposite side, as bestshown in Fig. 2 of the drawings.
Each one of theblades"3 isidentical in construction, and the angularity and pitch of the auxiliary blades 6 and 7 are adapted to provide a four-sided passage between'two of the blades 3, the contour of such passage being such as to deflect Water or air with considerable force in the opposite direction from that in which a body is propelled. It will thus be observed that a large Water and air impinging surface is provided in connection withja propeller that will cause a large dislacern'ent of water or air, either at a slow or igh speed. It is in View of thisfact, that we obtain a high degree of propelling power with a minimum ex enditure of fuel, consequentlv,-our propelier is highly eflicient for motorboats and similar craft The propeller is constructed of strong and durable metal and suitable means, as set screws and'nuts, (not shown) can be employed for securing the same upon the shaft.
' Having now described our invention what auxiliary blades angularly disposed with res ect' to said first mentioned blades, said auxi iar y blades arranged upon the opposite sides of said isosceles, triangle.
2.; A propeller comprising a hub, a plui ality of blades carried thereby, each blade comprising an isosceles triangle having its base at said hub and auxiliary blades carried by the sides of said triangle.
3. A propeller comprising a hub, a plurality of isosceles triangular blades carried thereby and each of saidblades'having its face at the hub, and angularly disposed auxiliary blades carried by the sides of each triangular blade...
