DRYER HOOD 7 Filed June 20, 1963 2 Sheets-Sheet 2 INVENTORS CARROLL I? REISS ARTHUR W. FORBFrIG ATTORNEYS United States Patent 3,348,316 DRYER H901) Carroll R. Reiss, Green Township, Hamilton County, and Arthur W. Forbriger, Silver-ton, Ohio, assignors to The Realistic Company, Cincinnati, Ohio, a corporation of Ohio Filed June 20, 1963, Ser. No. 289,302 1 Claim. (Cl. 34-99) This invention relates to a hood for a dryer such as a hair dryer or the like.

Certain forms of hair dryers include an inner domeshaped member having perforations therein and an outer dome-shaped member with a space therebetween into which warm, dry air is introduced to be discharged through the openings around a head inside the inner dome. It is desirable that the outer dome comprise more than a half of a sphere. An object of this invention is to provide a dryer of this type in which the outer member forms half a sphere, and an extension of the sphere is provided by a lip, which is a portion of the inner member.

A further object of this invention is to provide a device of this sort in which an inlet duct is attached to the outer member adjacent the edge thereof and in which a retaining band, which holds the inner and outer members in assembly, is adjacent the air inlet to reinforce the material of the outer shell at the inlet.

The above and other objects and features of the invention will be apparent to those skilled in the art to which this invention pertains from the following detailed description, and the drawings, in which:

FIG. 1 is a plan View of a hood for a dryer constructed in accordance with an embodiment of this invention;

FIG. 2 is a view in section taken on the line 22 in FIG. 1;

FIG. 3 is an exploded view of the dryer hood illustrated in FIGS. 1 and 2;

FIG. 4 is an enlarged fragmentary view in rear elevation of a buckle portion of the belt;

FIG. 5 is a view in section taken on the line 55 in FIG. 4;

FIG. 6 is a view partly in side elevation and partly in section showing one of a pair of dies for use in forming the inner portion of the hood; and

FIG. 7 is a view partly in side elevation and partly in section of a second die for use in forming the inner portion.

In the following detailed description and the drawings, like reference characters indicate like parts.

In FIGS. 1 to 3, inclusive, is shown a dryer hood constructed in accordance with an embodiment of this invention. The dryer hood includes an outer domed member 10 and an inner domed member 12. The outer domed member is substantially hemispheric in shape and includes an outwardly extending conduit 14 communicating with the interior thereof. A hollow support arm 16 can be attached to the conduit 14, and other portions of a dryer, not shown, can be attached to the support arm 16 in order to direct heated dry air into the interior of the outer mem- 3,348,316 Patented Oct. 24, 1967 ber 10. An annular outwardly extending flange 17 is formed at the lower edge of the outer member 10.

The inner member 12 has a central or main portion 18 which is dome-shaped and an intermediate portion 18a which is cylindrical and terminates in a return bent flange 19 which extends upwardly and outwardly from a lower edge of the inner portion. An outwardly extending flange 20 on the outer edge of the return bent flange 19 of the inner member 12 is of the same dimensions as the flange of the outer member 10 so that, when the inner and outer members are assembled, a channel-shaped band 21 can be mounted in engagement with the flanges 17 and 20 to hold the upper and lower members in assembly. A buckle 22 links ends of the band 21. The inner member 12 is provided with a plurality of spaced perforations through which heated dry air is discharged when the hood is in use.

The inner member 12 is molded between an inner die 24 (FIG. 6) and an outer die 26 (FIG. 7). The inner die 24 has a main dome-shaped portion 27 and an outer return bent flange 28 forming a slot 29 therebetween. The outer die 26 (FIG. 7) includes a dome-shaped body 31 complementary to the dome-shaped portion of the inner die. The body 31 terminates in an annular flange 32 having a cylindrical inner face 33 and can fit inside the slot 29 of the inner die.

As shown in FIG. 2, the radius of curvature of the outer member 10 and that of the return bent flange 19 are substantially equal so that the return bent flange is aligned with the outer wall of the outer member when the inner and outer members are assembled as shown in FIG. 2.

The dryer hood construction illustrated in the drawings and described above is subject to structural modification without departing from the spirit and scope of the appended claim.

Having described our invention, what we claim as new and desire to secure by Letters Patent is:

A dryer hood which comprises an outer member of dome shape, a conduit communicating with the interior of the outer member through an opening therein, an inner member including a main portion of dome shape, an intermediate portion of cylindrical shape, and a return bent flange, outwardly extending peripheral flanges on the outer and inner members, and means for linking the peripheral flanges to join the members together and to form a cavity therebetween, the return bent flange of the inner member being aligned with the wall of the outer member, there being discharge openings in the inner member.
