I UNITED STATES PATENT OFFICE JULIUS D. HAYNOWORTH, F MINNEAPOLIS, MINNESOTA, ASSIGNOR TO MCQUAY RADI- ATOR CORPORATION, OF MINNEAPOLIS, MINNESOTA, A CORPORATION OF DELAWARE ROTOR Application filed November 18,' 1929. Serial No. 407,988.
My present invention has for its object the i provision of an extremely simple and highly efficient rotor having laterally projecting and, generally stated, the of the novel devicesand combinations of devices hereinafter described and defined in the claims.
The invention, while capable of more general use,. has been especially designed as a fan rotor'for blowers and the like.
In the-acompanying drawings, which illustrate the invention, like characters indicate like parts throughoutthe several .views.
Referring to the drawings:
. Fig. l is a 'face view showing one form of the invention; I
Fig. 2 is a view partly in elevation and B artly in section taken on the line 2-2 of Fig. 3 is a perspective view of the inner unit removed from the rotor; and
Fig. 4 isa face View of the blank from which the inner unit is'formed.
For the sake of convemence, the inventlon Wlll hereinafter be referred to as. a' fan rotor,
and which rotor. is made up of one or more units, each. formed from a single sheet of formed on the aces material. illustrated plicate inner and outer units, each of which includes a flat body member 5 havmg an axial passageway 6 and circumferentiall spaced laterally rojecting blades or win s F of peripherial teet 8 The faces of the In the drawings, the" fan rotor on said bod member. teeth -8 and radiating from the center of the passa eway 6. Lock notches. 9 are formed in the acks of the teeth 80f the inner unit midway between the faces thereof. A hub 10 is rigidly secured to the outer fan rotor unit in axial alignment with its passageway 6, extends through the passageway 6 in the inner un1t blades 7 ofjthe .ali
and is mounted on a shaft 11 for therotor. In assembling the fan rotor units, the
ed with the lock notches,9 and-inserted en wise therethrough and between the blades of the inner unit b one of said units 1n respect to the other.
an axial movement of When the rotor comprises two substantially duof the passageway 6.
ence the blades7 are on lines the body members,
outerunit are longitudinally units are assembled, their body members 5 are parallel, direct contact the one with .the other and rigidly connected near their peripheries by spot welding 12, as
indicated in Fig. 1. gagement, between the blades 7 of the outer fan rotor unit-and the lock notches in the The interlocking en-- inner units thereof, holds said two units against circun'iferentlal movement in respect to each other and automatically centers the same with the blades 7 of the outer unit midway between the blades 7 of the inner unit.
The connected body members 5 make a rigid structure, and by .assemblin two or more units a rotor with the desire number of blades may be readily produced.
- The blank from which the inner rotor unit is formed is illustrated in Fig. 4,,and it will cutting the periphery of the blank to form the outer longitudinal be noted that the same is produced simply by edges and ends of vthe blades 7 and by cutting said blank at the inner longitudinal edges-of said blades the formation of said unit is completed except the bending of said blades laterally on the folding lines 13. The passageway 6 and lock notches 9 are formed by punching. Bythus forming the blades 7 a solid body structure is produced which adds greatly to the rigidity of the rotor.
The blank, from which the outer unit is formed, is identical with the blank shown in Fig. 4 with the exception as to the diameter What I claim is: A device of the class described comprising substantially duplicate inner and outer units each formed from a single sheet of material, the body members of said units being axially aligned and having toothed eripheries, and blades on the faces of the teet that radiate substantially from t e axes of said inner unit having radial lock notches in the backs of its. teeth in which the blades of the outer unit extend and .lyin in planes
