W. MEYER HAIR DRIER March 3, 1931.

Filed March 8, 1928 Jam/M124 4 Patented Mar. 3, 193} tweete- E MEYER, O15 CIEZEGA, ELEJQZES DRIER Application filed March a, 1828. ene The. aeaeaa This invention relates to hair driers and its object is the provision of a generally improved, simple and relatively inexpensive outlet construction for concentratin the drying stream and increasing the spec with which the drying action is effected, and an outlet construction that will confine the dischargin drying stream and direct the same more e :ectively over the head to dry the 1 hair more evenly or uniformly.

The outlet construction of the present invention is also adapted for effectively positioning the head with respect to the discharging stream and for permitting movement of the head relative the drier without impairing the drying action.

For purposes of illustration I have illustrated the invention in connection with the drier more fully disclosed in my co-pending application, Serial No. 211,121, filed August 6, 1927, which application has matured mto Patent No. 1,686,024, issued October 2, 1928, but it is to be understood that the invention is not limited to use with or embodiment in that particular drier, but may be used with or embodied in other driers as and where suitable or desired. I have also illustrated the present invention as an attachment and as being adapted for. movement into and out of operative position, as well as out of the way when not desired and without removing it from the drier. It is to be understood,

however, that the present outlet construction 1 may be embodied as an integral part of the drier, without being adjustable ormovable out of operative position, or it may be in the form of an attachment adapted for movement into and out of operative position or for complete removal as desired; Other variations are also contemplated within the see c of the appended claims. A

ccording to the present invention I provide a hooded outlet which is preferably of a size to comfortably receive the head and I term this outlet to confine the drying stream without appreciable loss and to concentrate the same to increase the speed and effectiveness of the drying action. This hood is the line 22 of Fig. 1-;

preferably formed to direct more of the drying stream or to concentrate the stream more on the parts of the head where the hair is thicker and less down the back of the neck and along the sides where the hair is thinner. Excessive beating down the back of the neck .and along those portions of the head where the hair is thinner is avoided and ample heating and/or drying where the hair is thicker is provided.

The invention is illustrated in the accompanying drawing, in which:

Fig. l is an end view of the discharge or outlet end of a drier embodying the present invention;

Fig. 2 is a longitudinal section taken on Fig. 3 is a fragmentary detail section through the outlet or discharge end of'the outlet hood, taken on the'line 3-3 of Fig. 1; and

"Fig. l is a fragmentary detail section taken on the line H of Fig. 2.

The drier shown comprises a generally cylindrical shell 5 havin an open outlet end 6. The rear end of the s iell 5 is attached at 7' to a generally cylindrical drum 8 which forms a continuation of the inner or rear end of the shell 5. The cross section of the drum 8 and shell 5 may, of course, vary from cylindrical as desired. The drum 8 and shell 5 may be of suitable sheet metal construcso tion, although this may, of course, be varied widely.

At the rear end of the drum 8 is a head or 7 end member 9, suitably secured to the ad'acent rear end of the drum 8 at 10. A. suita 1e electric motor 11 is mounted axially or centrally in the head or end member 9, preferably with the revolvable motor shaft 12 disposed axially with respect to the drum 8 and shell 5.- The end or head member 9 is also .provided with suitable inlet openings 13 through which the air is drawn into the device and discharged longitudinally throughthe shell 5 toward and from the outletjor discharge end 6.

Arranged forwardly of the motor 11 and mounted marginally m the rear end of the shell 5 is a transverse partition 15. The par.- tition 15 has a conical axially disposed open ing 16, the smaller end of which opens rear- 100 16, preferably with its forward edge in sub--- stantiallythe plane of the rear end of the opening 16. The propeller '18 is suitably -fined upon the motor shaft 12 so that it will rotate with the motor shaft, upon rotation of the same, drawing air through the rear inlet openings 13 and impelling the same forwardly through the shell and out through the outlet 6.

v For the purpose of preventing swirling or circular motion of the air through the device, the shell 5 is provided, forwardly of the partition 15 with suitable anti-swirling members 20. The anti-swirling members 20 may be arranged generally radially within the shell andmay be suitably attached or mounted along their rear edges upon the partition 15. A standard or other suitable electric light socket 21 is mounted axially within the shell 5 upon the anti-swirling members 20 and is adapted to receive a lamp 22 which may be a high power electric light or incan descent lamp, such as a nitrogen or high powered tungsten filament lamp. The lamp 22 is provided with a reflector 23 disposed rearward of the lamp-and directed forwardly, the lamp 22 being preferably positioned in the focus of the reflector, or otherwise as desired with respect thereto. The reflector 23 is shown as mounted at 24 upon the socket 21 and the periphery of the reflector 23 is preferably spaced at 25 from the inner surface of the shell 5.

A heating coil 26 is shown as mounted upon the anti-swirling members 20 for the purpose of suitably heating the stream of air in its passage from the inlet 13 to and out through the outlet, 6. i

The drier is provided with a switch 30 and the current supply conductor means (not shown) may be connected to the motor 11,.

heater 26' and lamp 22 through the switch means 30. The switch 30 is provided with suitable lever means 32 which is preferably adapted for separately controlling the motor,

heater and lamp circuits although, of course,

the particular circuit connections may be varied. The conductor means is preferably provided with a suitable connector for connection with a standard or other suitable outlet. The device is provided with suitable means 34 for mounting the drier upon an upright stand 35 or other suitable support. I The drier is preferably swingable about the piv- 0t 36 and is preferably adjustable up and down vertically to adjust the height or vertical position of the drier. v

In operating the drier, the lamp 22 constitutes the source of radiant heat and radiant light. The rays of light and the heat admitted by the lamp 22 are reflected by the reflector 23 and projected outwardly through the outlet end 6.

When the motor circuit is closed, the fan 18 is started and air is drawn in through the inlet openings 13 and projected with the radiant heat and light through the discharge end 6 of the device, and upon the hair and scalp or other surface. The air is blown already pointed out, in the form of a hooded attachment designated generally at 38.. The hood 38 which may be of sheet metal, or other suitable construction comprises a generally cylindrical wall 39 closed at its rear end by a radial end wall 40. The end wall 40 has a collar or sleeve 41 which may be formed integrally with the end wall 40 or otherwise attached thereto. telescoping over the adjacent end ofthe shell 5 for operative position upon the outer end of' the shell 5, as shown. The collar 41 may be and preferabl is adapted for sliding move- Thecollar 41 is shown as ment longitu inally along the outer surface of the shell 5 for moving the hood 38 out of operative position and out of the way rearwardly on the hood when its use is not desired. When the hood 38 is positioned rearwardly out of the way, the outlet 6 may constitute the outlet or discharge end of the drier directly for use wherever use of the hood is not desired. The hood 38 may even be removed entirely for use of the device without the hood and where it is movable on the shell 5 from one position to another it may be held frictionally in its difierent positions or suitable clamping or other means may be provided for fastening the hood in its different positions.

The forward or outer end of the generally cylindrical wall 39 of the hood terminates along a diagonal or oblique line, as indicated at 48 and extending along the top and down alongthe sides of the forward end of the generally cylindrical wall 9 is a flange 50. The lower ends of the side portions of the flange 50, which may be rounded at 52 into the forward end of the cylindrical portion 39 are preferably narrower at 53 than the to or upper portion 54 of the flange, the wid h of the flange preferably decreasing gradually from the median part of the top down along each side to the lower end thereof. The angle of the median upper part or top of the flange 50 to the cylindrical wall 39, as indicated at 56 is'also preferably less or sharper than the angles 58 (Fig. 3) between the lower ends of the side portions 53 and the cylindrical wall 39 and the angular relation between the flange 50 and the adjacent end of nreaaeo the wall 39 referably decreases or becomes sharper gra uallyv and uniformly from the lower ends 52 to the median the top or upper portion 54 of the flan e.

The outer edge of the flange 5U is preferably dimensioned to comfortably receive the head as indicated in dotted lines at 60 and the lower ends of the opposite sides of the flange 50 terminate short of? the bottom of the wall 39, leaving the open bottom 62 of a width suitable to comfortably receive the neck or back portion of the head.

The flanged end 50 of the hood forms a concentrating ring for concentrating the drying stream and increasing the speed thereof and the speed of the drying action and at the same time the shape and varying angle of the flange to the cylindrical wall 39 of the hood coupled with the disposition of the outlet 6 with reference thereto as will be explained presently, confines the drying steam and directs the same more edectively over the head to dry the hair more evenly or uniformly. The outlet 6 preferably opens through the rear wall 40 eccentric with reference to the 'enerally cylindrical wall 39 and is disposed closer to the bottom of the hood. This with the enlargement of the wall 39 over the shell 5 provides ample space around the sides and. top of the hood for receiving the head and the downward disposition of the outlet 6 provides suitable space or clearance over the top and around the sides of the head for permitting the drying stream to pass around the head. The flange. not only confines and concentrates the drying stream at the forward end of the hood, but it deflects the same. back efiectively along the forward portions of the top and sides of the hair bearing portion of the head.

The varying angular disposition of the flange directs more of the drying stream or concentrates the stream more on the part of the head where the hair is thicker and less along the part of the head where the hair is thinner. The open bottom portion 62 eliminates any objectionable projection or direction of the drying stream down the back of the neck and excessive heating down the back oi'the neck and along those portions of the head where the hair is thinner is avoided.

For the purpose of deflecting the stream of air beyond its passage through the axial opening 16, the blades or anti-swirling members 20 maybe rovided with deflectors 70. These deflectors 0 are shown in the form of integral ears struck out of the radial walls of the anti-swirling blades and adapted for deflecting the air out better across the heater 26 to secure a more complete or more uniform heating of the stream of air in its move- "ment past the heater 26. The deflectors need not be integral with the blades 20 and may be otherwise arranged and mounted within the casing or shell of the device. lhe present device heats the drying stream better and With'less current Iclaim:-- I
