ATTO R N EY Patented Feb. 13, 1934 UNITED STATES PATENT @FFICE Application January '7, 1931, Serial No. 507,268 Renewed December 13, 1933 4 Claims. (01. 34-26) This invention relates to hair driers and has for an object the provision of a device by means of which hot air may be evenly distributed over the entire head, and the amount of air supplied to any portion regulated, so that sufficient air may be supplied where the hair is thick, and a proportionately small quantity supplied to the thin hair. This overcomes the disadvantage present where the hair is dried by means of a single blast drier,

which dries the hair in sections and subjects the user to a blast of uncomfortable hot air.

Another object of the invention is the provision of a device which may be used for drying long hair and hair of shoulder length, and for drying permanently waved hair and hair in flat curls against the neck, as well as short or bobbed hair, and will in addition, dry white hair without causing it to turn yellow.

Another object of the invention is the provision of a device, which in addition to the above and other advantageous features, is simple in construction, easy to control, and may be used to spread steam vapor over the hair for naturally curly hair, or permanently waved hair. The invention may also be used to treat the hair by adding oil or other liquid to the vapor.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and. pointed out in the appended claims.

In the drawings:

Figure 1 is a side elevation of the invention.

Figure 2 is a central vertical sectional view.

Figures 3, 4, 5 and 6 are sectional views taken respectively on the lines 3-3, i4, 55 and 66 of Figure 1.

Figure 7 is an-elevation of the distributor body 40 looking at the inlet end.

Figure 8 is a detail elevation of one of the valves for the discharge chambers.

Figure 9 shows a side and end view of one of the valves for controlling the discharge nozzles.

Figure 10 shows a plan and edge view of one of the valve springs.

Figure 11 is a fragmentary view partly in elevation and partly in section and showing a different form of nozzle.

Figure 12 is a sectional view of still another form of nozzle.

Figure 13 is a plan view illustrating the modified form of nozzles in assembled position.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 12 indicates the body of the device which is adapted to be arranged in communication with a suitable blower, or with a source of steam vapor. For this purpose, the body is provided with an inlet passage 13.

The body is elongated and is provided. with oppositely extending

nipples

14 and 15, and with a nipple 16' which extends from the top of the body. The lower end of the body is provided with a plug closed drain opening 17. 1

Secured within these nipples are discharge nozzles, the nipples 14 carrying discharge nozzles 18 which are adapted to encircle the crown of the head of a person being treated. These nozzles 18 are provided with apertures 19 for the escape of hot air or steam vapor. The nozzles are removably held in place by means of set screws 20.

The nipple 16 has secured therein by means of a set screw 21, a nozzle 22. This last mentioned nozzle extends centrally above the nozzles 18 and is provided with discharge openings 23. The nipples are provided with superimposed nozzles 24 which are disposed below and in superimposed relation with the nozzles 18 and are adapted to extend along opposite sides of the head of the person being treated. These nozzles 24 are provided with discharge openings 25.

Each of the nipples is provided with a valve chamber 26, within which operates a valve 27, the latter acting to control communication between the body 12 and the various nozzles, so that air or steam may pass from these nozzles in regulated quantities. Springs 28 act to hold the valves 27 in position.

Extending transversely of and communicating with the body 12 are laterally disposed discharge chambers 29. These chambers are provided with discharge openings 30 which are controlled by valves 31. These valves are held in position by means of springs 32 which bear against the ends of the chambers 29 and against disks 33 which are secured to the valves by means of screws 34. The valves 27 are provided with finger pieces 35, while the valves 31 are provided with finger pieces 36.

When used as a drier, the device is connected in any suitable manner with a blower which supplies hot air to the body 12. The device is placed about the head of the person whose hair is being treated and the

valves

27 and 31 are adjusted to supply the proper quantity of air in accordance with the condition of the hair. The nozzles 18 will supply air around the crown of the head while the nozzle 22 supplies air over the top. The nozzles 24 supply air along opposite sides of the head, while the distributing chambers 29 supply air to the back of the head. By adjusting the valves an even and proper distributionof air may be obtained.

In addition, the device may be connected with a suitable source of steam vapor and the latter supplied to the hair as required.

The nozzle shown in Figure 11 is of sectional formation in that it includes a main section or nozzle 37 and a nozzle tip 38. This nozzle is hingedly or pivotally secured to the nipple 39 as shown at 40 and may be used in substitution of the nozzle 22 for distributing air over the top of the head. The pivoted connection 40 is such that the nozzle may be moved laterally to opposite sides of the center of the head and fiow through the nozzle may be controlled by means of a valve 2'7. A handle 41 extends from the nozzle 3'? for convenience of manipulation. The outer end of the nozzle 37 has a nozzle tip 38 pivotally secured thereto as shown at 42, the pivotal connection being such that the nozzle tip 38 may move in a direction at right angles to the movement of the nozzle 37. The tip 38 is provided with a port 43 which is adapted to be moved into and out of register with a port 44 at the outer end of the nozzle 37 so that the nozzle may be moved pivotally to cut off flow therethrough. For example when the nozzle is moved in a direction away from the head the

ports

33 and 34 will be disaligned and flow into the tip will be interrupted. The tip is provided with a handle 45.

If desired the inner end of the nozzle may be pivotally attached to the head as shown in Figure 12. In this figure there is illustrated one of the side nozzles whose inner end is provided with a rounded enlargement 46 which operates in a socket 47. This nozzle which is indicated at 48 may be substituted for any one of the side nozzles and may be brought into position to permit flow into the nozzle through ports 49 and-5l. However, when the nozzle is moved outward away from the head as indicated by the dotted lines in Figure 12, these

ports

49 and 50 will be disaligned. A handle 51 is provided upon the outer end of this nozzle.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is:-
