HAIR DRIER Filed April 30, 1929 INVENTOR 116/2 ATTORN EY.

UNITED STATES PATENT OFFICE JAMES W. RAINEY, F S'L'LOUIS, MISSOURI HAIR DRIER Application filed April 30,

This invention relates to certain new and useful improvements in hair driers or' similar devices, the peculiarities of which will be hereinafter fully described and '5 claimed.

The main objects of my invention are to provide means for guiding and distributing heated or other currents of air to heads of hair after washing, treating for waving,

or other arrangement of the hair, for the purpose of drying or setting the treated hair in the desired position; secondly, to

direct the air to the hair in predetermined divided currents according to the requirements of the several parts of the scalp; and thirdly, to .deliver such currents of air at lower velocity and more expanded condition than received from the source of supply.

'20 It has been demonstrated that air currents impinging on moistened air with considerable velocity and concentrated location, produces a change in the color of the hair at the points so treated, A varie- 95 gated appearance is thus produced, which my device is found to avoid by the gentle, distributed air currents which it is adapted to deliver. I

. In the accompanying drawing in which 80 like reference numerals indicate corresponding parts,

Fig. 1 represents a side elevation of a fan and delivery pipe with my improvements applied thereto;

Fig. 2, a vertical section of one of my hair driers on the line 2-2 of Fig. 1;

Fig. 3, a face view of the same;

Fig. 4:, an enlarged sectional detail of one of the air outlets showing its rounded edges;

Fig. 5, a similar view showing greater rounded edges; and

Fig. 6, a similar view of my rounded and bell-mouth outlet.

Referring to the drawing, the numeral 1 designates a fan driven in the usual manner by motor or belt connection (not shown) and having a delivery pipe 2 attached to the outlet. At or near the outlet 1929. Serial No. 359,359.

the usual electric heating coil is located as indicated.

I At one or more points along said pipe lateral'branch pipes 3 with cut-01f slides 4 are located at convenient spacing for chairs to seat customers and allow them to insert their heads in canopies 5 mounted on said branch pipes. Adjustable stands allow of varying the height of the canopies to suit, as the pipe 2 is rotatable at its connection to the fan outlet. This hair drying canopy consists of walls in cylindrical sections 6 and 7 and a reducing conical section 8 with collar 9- fitting the respective branch pipe 3connected to form a curved (or other shaped) covering for the head, and also to constitue an expanding'chamber for the air delivered to it at considerable velocity and pressure corresponding to the fan speed.

The outer section 6 has a varying 0r eccentric rim 10 (Fig. preferably wider in front than at the rear, and to it is secured a perforated inner cylindrical (or other shaped) section 11, of suitable size to enclose loosely the head as indicated in Fig. 2.

On this inner section or otherwise, is

mounted a conical dome section 12also perforatedwhich serves as a distributing. deflector of the air currents from the branch pipe 3.

The perferred wider rim at the front and inclined position of the inner section 11 with respect to outer section 6 (Figs. 3 and 2), form an annular chamber of varying width and outwardly flaring walls at the front (Fig. 2), adapted to expand the air and reduce its velocity yet more as it seeks the front outlets. Thisconstruction tends to produce gent, ler air currents through the perforations" near the forehead of the customer than at the neck and top of the head where the hair is thicker and rolled up when long.

The dome distributor has its axis X inclined so that the side portion A (Fig. 2) is disposed substantially perpendicular to the entering air currents, while the opposite portion B is substantially parallel to said currents entering the chamber on the axis 100 Y. The back hair of the customer therefore will receive more penetrating air currents through the outlet perforationsin the adjacent portion A, than the top halr w ll receive through the outlet'perforatmns: 1n the portion B,-which is evldently desirable.

Also, the outlet perforations in this distributor are so located as to produce .lesser currents to the top of the head than at the.

back where the perforations oppose the full currents of expanding air from the branch pipe. Thus the quantity and veloclty of the air through the various outlets are adapted to the parts of the head and amount of hair thereon as stated.

These outlet perforations are preferably rounded at their inner edges, or otherwise adapted to prevent a rushing sound as t he air passes through them at various velocltles and pressures. Thus Fig. 4 shows the nner edge 13 slightly rounded; Fig. 5, said edge rounded yet more and projecting outward at 14: while Fig. 6 shows said inner rounded edge combined with an outer bell-mouth projection 15 adapted to expand and spread the air currents passing outward to the customers head of hair. Any or all of these outlets-or others-may be used in said dome and inner section to assist in producing the gentle, distributed air currents above described.

The combined area of these outlet perforations is greater than the area of the branch pipe 3, so that the expanded air in the expansion chamber passes these perforations at less velocity and pressure than it has on entering said chamber, for the purpose above fully set forth.

Furthermore, by the use of my hair drier in multiple as indicated in Fig. 1, the customers after their hair is washed or otherwise moistened, take their places under the respective canopies and the drying is quickly accomplished without the continued attention of an attendant,who is thus left free to serve other waiting customers. Thusmore customers can be served by such attendant in shorter time of waiting, as experience has fully demonstrated.-

I claim:

A hair drier comprising outer walls in cylindrical sections and a reducing conical section joined together to form a curved covering for the head and a relatively large expanding chamber adapted to receive heated air under pressure, an inner peri forated section and a perforated conical drum therefor, and an eccentric rim wider in front than the rear and connecting said outer section and inner section and forming an annular chamber of varying width, substantially as described.

In testimony whereof I have afiixed my signature.

JAMES W. RAINEY.
