2 Claims. 1

"This invention relates to a support foran electrical applianceand particularly a: handle'for a hair-dryer or the like in which handlei the-hair dryer or other appliance is rotatably mounted for adjustment to various angles.

' One object of the invention isto-provide asim ple connection between a. handleand an appliance for the adjustment just. referred to so that .when

-Another object is to provide a handlestruc- .wture with a novel type of connection between :the I handle and an appliance such as onevhaving-l an electric motor, said connection consisting of a C-shaped spring adapted to partially encircle the motor and permit rotation of the motor therein for adjusting the angle of a discharge nozzle or the like carried by the motor housing without the necessity of providing pivot connections, clamp screws therefor and the like, the handle being specially constructed for cooperation with a novel type of connection between it and the c-shaped pring.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my support for electric appliance, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and i1- lustrated in the accompanying drawings, wherein:

Figure 1 is a side elevation of a support embodying my invention and including a handle, a hair dryer being shown supported thereby, the hair dryer having a discharge nozzle shown directed downwardly at a slight angle in solid lines and upwardly at a slight angle in dotted lines, the handle and dryer being mounted on a supporting base which is also part of the support.

Figure 2 is a perspective view of the handle per se with the hair dryer removed.

Figure 3 is a plan view of Figure 1.

Figure 4 is a vertical sectional view on the line 4-4 of Figure 3; and

Figure 5 is an enlarged end elevation of the upper end of the handle.

On the accompanying drawing I have used the reference character B to indicate a base, H a

handle, and M a motor. The base B may be molded of suitable plastic material such as Bake- I lite and has: an opening 5 l D formed therein to vreceivea' shouldered pin IZ. The shoulder of the pin fits against a sheet'metal reinfQrcement -M countersunk in the uppersurface of the-base B and is threadedat its lower end for a lock nut I6 'formounting the pin rigidly with respect to; the '---base.

or=the=like and has a bore '10- The handle H mayalso bemolded of-Bakelite It to rotatablyreceive the pin 'l2. The upper end of the bore- I8 terminates in a shoulder 2H for the-head'22 of a'tie bolt 24, the'purpose'of which will hereinafter appear.

--ternal ribs 26'are provided and a from: each Adjacent the upper end of the handle H, in-

pair of locating projections 28 are provided projecting inwardly side wall of the handle as shown in "Figure 5. The ribs 26 between the projections '28 support a rectangular piece of sheet metal 30 '--having ahole 32 therein to receive the bolt 24.

Seated on the sheet metal 30 is a C-spring C which has a pair of offsets 34 and 36 connected by a cross piece 38 which is also perforated to receive the screw 24. A washer 40 above the cross piece 38 is positioned on the screw 24 and a lock nut 42 completes the assembly so that the C- spring is rigidly connected to the handle H when the screw is tightened with respect to the nut. When the C-spring is seated against the sheet metal 30, its arms are seated against upper edges 43 and 44 of the handle to provide a type of support that prevents any Wobbling of the G-spring relative to the handle.

The arms of the C-spring are lined with strips of felt 46 cemented to the arms and the arms are sprung from the full-line position of Figure 2 to the dotted position thereof around the housing 41 for the motor M as shown in Figures 3 and 4 for supporting the motor and its housing. The housing is usually plated and polished and the felt prevents scratching it. The motor housing 41 preferably has a pair of beads 48 therearound to position the C-spring with respect to the housing.

The housing illustrated terminates in an air discharge nozzle 50 and the housing encloses the motor M which motor is for driving a fan (not shown) as is usual construction in small handheld hair dryers of the type disclosed. The base B is then provided so that the hair dryer can be placed on a dresser or the like and by the two adjustments (1) in the vertical plane by rotating the motor housing 41 in the C-spring, and (2) in the horizontal plane by rotating the handle H on the pin I2, various desired adjustments can be had for directing the nozzle at the desired angle.

The type of connection between the handle Some changes may be made in the construction and arrangement of the parts of my support for electric appliance without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:

1. In a support for a hand-held or basesupported electrical appliance, a handle member having a socket in the upper end provided with a bottom, said bottom being located adjacent the peripheral edge of said upper end, a C-shaped spring having its central portion located in said socket and rigidly connected with said handle against said bottom, the arms of said C-shaped spring being seated at their lower portions against the upper peripheral edge of said handle, said spring having its arms partially surrounding a substantial cylindrical portion of the appliance and frictionally retaining the same relative to said handle member, said cylindrical portion being slidably rotatable in said arms, said arms being lined with non-metallic material, said handle having a bore in its lower end, and a base having a pin projecting upwardly into said bore for rctatably supporting said handle.

2. In a supporting structure for a hand-held or base-supported electrical appliance, a handle, ribs formed therein, a cross-piece supported on said ribs, a c-shaped spring seated on said crosspiece, a tie bolt in said handle for holding said G-shaped spring rigidly against said cross-piece and said cross-piece rigidly against said ribs, said cross-piece and supporting ribs being located adjacent the upper end of said handle whereby the arms of said C-shaped spring seat at their lower portions against the upper edge of said handle, the bore for the head of said tie bolt being adapted to receive a pin projecting upwardly into the lower end of said handle from a supporting base, and the arms of said C-shaped spring being lined with resilient material and adapted to partially surround and irictionally engage a cylindrical portion of an appliance, said cylindrical portion being slidably rotatable in said arms.
