G. M. CAPELL AIR IMPELLER OR PROPELLER Filed Sept. 2. 1921 ATTY.

Patented Sept. 4, 1923.

GEORGE MIARIE CAPELL, DECEASED, LATE 0F PASSENHAM, NEAR STONY STRATFORD, ENGLAND; BY ROBERT ALFRED BLAKE, TRUSTEE AND LEGAL REPRESENTATIVE.

AIR IMPELLER OR PROPELLER.

Application filed September 2, 1921. Serial No. 498,096.

To all whom it may concern:

Be it known that GEORGE MARIE CAPELL, deceased, subject of the King of Great Britain, late residing at Passenham, near Stony Stratford, in the county of Bucks, England, has invented new and useful Improvements in and Relating to Air Impellers or Propellers, of which the following is a specification,

This invention relates to air impellers or propellers and consists of certain improvements hereinafter expressed, in the type of impeller or propeller adaptable to and capable of:-(a) creating a current of air when caused to rotate in stationary mountings, (b) advancing through the air when mounted and caused to rotate as the propeller of an aeroplane and (0) being The invention consists in providing a conical containing ring around the blades and in some instances providin in such form of impeller a lip upon one-e go of the blades.

Figure 1 is an elevation of an impeller or propeller constructed with the improved containing ring. Figure 2 shows a portlon of an impeller constructed with the improved containing ring and improved blades. Figure 3 is a section on tortuous line M--M Figure 1 lookin from right to left and showing a method of mounting. Figure d is a section at YZ Fi re 1, and Figure 5 is a section at W- Figure 2, showing the improved blade. 7

As previously proposed the blades may be formed by cutting suitable slots in a disc C and bending the parts A of the blades obliquely out of the plane of thedisc According to the present invention the outer extremities of the blades A C are suitably attached' to the interior of a conical containing ring E, converging in the direction of the portions A. This ring E may have a cylindrical extension H beyond the portions A of the blades. The disc C is attached at its centre to a flanged sleeve F which is fixed and carried upon a shaft G. The sleeve may be contained within a coneshaped member P thus forming a cone shaped boss which guides the air to the blades.

The shaft G may be j ournalled in bearings as shown at K.

A modified blade is formed by bending the edges of the portions of the disc C remote from the portions A obliquely out of the plane of the disc to form lips as shown at L in Figures 2 and 5 this bend being in a reverse direction to that of the portions A. What is claimed is 1. In an air impeller, blades each consisting of a portion of a disc perpendicular to the axis of said impeller and a ortion oblique to said axis, and on the lea ing side of said perpendicular portion, and a conical ring converging in the direction of said oblique portions secured to the outer extremities of said blades.

2. In an air impeller, blades each consisting of a portion of a disc perpendicular to the axis of said impeller and a portion oblique to said axis and on the leadin side of said perpendicular portion, a conica ring converging in the direction of said oblique portions secured to the outer extremities of said blades and a cylindrical extension of said ring.

3. In an air impeller, blades each consisting of a portion of a disc perpendicular to the axis of said impeller, a portion oblique to said axis and on the leading side of said perpendicular portion, and an oblique lip remote from and oppositely directed to said oblique portion.

4. In an air impeller, blades each consisting of a portion of a disc perpendicular to the axis of said impeller, a portion oblique to said axis and on the leading side of said perpendicular portion, an oblique lipremote from and oppositely directed to said oblique portion, and a conical ring converging in the direction of said oblique portions secured to the outer extremities of said blades.

meme? 5. In an air impeller, blades each consisting of a portion of a disc perpendicular to the axis of said impeller, a portion oblique to said axis and on the leading side of said perpendicular portion, and an oblique lip remote from and oppositely directed to said oblique portion, a conical ring converging in the direction of said oblique portions secured to the outer extremities of said blades and a cylindrical extension of said ring. 10

In testimony whereof I have signed my name to this specification.

ROBERT ALFRED BLAKE.

Trustee and legal representative of George Marie Capell, deceased.
