'H. BUCHANAN.
AIR PROPE LLER. APPLICATION FILED SEPT. 23, 1910.
Patented Apr. 9, 1912.
UNITED STATES IiTEN-T OFFICE.
JESEY H. BUCHANAN, OF
MIDWAY, TEXAS, ASSIGNOR OF ONE-FOURTH T CHALLEY H. BUCHANAN, 0F MIDWAY, TEXAS.
AIB-PROPELLER.
BUCHANAN, residing at State of view is. to provide a simple propeller of I specification and high efliciency which can be cheaply constructed and carries on its supporting arms rectangular vanes or blades braced by cords to the arms.
With the above and other objects in view the invention consists in certain construe tions, combinations and arrangements of parts, clearly described in the following clearly illustrated in the accompanying drawings, in which 2-- Figure 1 is a plan view of the improved propeller. Fig. 2 is a sectional View taken on the line 2-2 of Fig. -1. Fig. 3 is a detail perspective view of a fragmentary portion of the central bearing collar and showing the manner of securing one of the arms thereto.
Referring to the accompanying drawings illustrating thepractical embodiment of the invention 5 denotes a central bearing collar having a tubular projection 6 -to receive a drive shaft and braces 7 for strengthening said projection 6. The collar 5 is provided with four or more radiating arms 8 on which the blade supporting bars or arms 9 are mounted.
The arms 8 of the collar 5 are formed with sockets to receive the inner ends of the blade supporting arms 9 and said blade supporting arms are secured to the arms 8 by bolts or screws 10 and by adjusting screws 11 which extend at right angles to the arms Specification of Letters Patent.
Patented Apr. 9, 1912.
Application filed September 23, 1919. Serial No. 583,518.
' '9 into the collar arms 8. On the ends of the arms 9 rectangular blades 12 are mounted.
The blades are provided with eyes 13 located near their outer ends and brace ropes or wires 14 are connected with the eyes'13 and hooks 15 fastened to the arms 9. The
'brace ropes 14s. of each blade extend diagonally toward one of the adjoining arms 9 and are connected thereto instead of being connectedto its own arms. In this way the blades will be effectively braced on the arms.
The many advantages of a construction of this character will be clearly apparent as thesame is one which may be economically as well as easily manufactured.
Particular attention is called to the fact i that the blade supporting arms may be readily removed and the blades replaced or repaired without removing the propeller from the machine. It will also be. noted that said arms may be conveniently adjusted.
WVhat is claimed is 1. In an air propeller, a collar having a series. of radiating arms, supporting arms mounted on the arms of the collar, rectangular blades mounted on the ends of the second arms and braces connecting the blade of each arm with the adjoining arm.
2. In an air propeller, a collar having a series of radiating arms, a series of blade supporting arms adjustably secured to the collar arms, rectangular blades mounted on the ends of the blade supporting arms, eyes secured near the ends of the blades, eyes secured on the blade supporting arms and braces extending diagonally from the blade of each arm to an eye of the adjoining arm.
In testimony'whereof, I affix my signature, in presence of two witnesses.
