Application July 11, 1935, Serial No. 31,806- 1 Claims. (01. 34-20) "This invention relates to multiple service hair driers or the like, and provides improvements therein:

This invention provides an improved apparatus comprising a plurality of feeder ducts and a pluraiity' of delivery devices, such for example as hoods adapted to partially surround a head, by which air from one or another of the feeder ducts,

or in any desired proportions from the plurality of ducts, may be admitted to the delivery devices and which proportions may be different for each delivery device. That is, for example, cold or unheated air may be admitted from one feeder duct to one delivery device, hot air from another feeder duct ,to a second delivery device, mixtures of hot and cold or unheated air in a desired proportion may be admitted from two feeder ducts to a third delivery device, and mixtures of hot and cold air' in a different desired proportion may be admitted from the two feeder ducts to a fourth delivery device and so on.

By the present improvements means for regulating theadmission of air are provided by which the area for the admission of air to the delivery devices, whether it be from one or another of the feeder ducts, or from two of tlie feeder ducts, remains constant.

By the present improvements also means may be provided at each delivery device for effecting remote control of the regulating means thereat, so that a person whose head is in a hood having her hair dried, can effect changes in the tem-' perature of the air to suit her comfort. I

The invention may also further provide means for automatically cutting of! the flow of air to one or more of the hoods after the use thereof has finished to prevent idle flow of air from the delivery device or devices.

The invention further provides a novel arrangement of the elements of a multiple service hair drier by which the device is simplified, made more economical to construct, and is enhanced in utiutyi Alf-Embodiment of the invention is illustrated in the accompanying drawings wherein:

Fig. 1 is a front elevation, with parts in section, illustrating so much of the apparatus as is necessary to illustrate the invention. v

Fig. 2 is a vertical sectional view on the line Fig. 3 is an enlarged vertical sectional view illustrating the means for regulating the flow from the feeder-ducts to air delivery.

Fig. 4 is a horizontal sectional view on the line H, Fig. 3. 1

Fig. 5 is a vertical sectional view taken trans versely of the feeder ducts, and showing a modifled form of the means for regulating the flow of air from the feeder ducts to a delivery device.

Fig. 6 is a cross-section on the line 66, Fig. 5. 5 Referring to said drawings, numeral Ill designates a central air-blower comprising a motor. driven fan I2, a fan casing ii, an air receiver IS in communication with the fan casing l3, and also in communication with vertical flues l1 and, 10 4:, zhich flues communicate with feeder ducts One of the flues, as the flue l8, conducts cold or unheated air from the reservoir ii to one of the feeder ducts, as the duct 2|. The designation of 15 air in this flue l8 as being cold or unheated airv does not exclude the air having some warmth, as the air drawn in by the fan l2 may become warmed by the heat given off by the machine, by recirculation of the air, or otherwise.

Means are provided for heating the air which isconducted through the feeder ducts 20. This means preferably comprises a heater 22 located in the flue IT. The heater 221s located above the receiver i5, so that air in the receiver l5 may dis- 25 tribute in the fines l1, It in accordance with the variations of resistance to flow offered by these flues and the other parts of the apparatus in communication therewith, but flow of hot air from the flue I! to theflue I 8 will not occur. The 30 heater 22 is preferably in the form of a drum 24 ,closedto the flue I1, and containing a suitable heating element 26, preferably in the form of a gas burner. The fan, air receiver and dues are preferably contained in a housing 26. The drum 35 2c is in communication with the exterior of the I housing 26 by means of openings 30, 3| and pas-. sages passing through the flue I! to the interior of the drum. The drum 2!, being heated, transfers heat to the air flowing around it in the flue IT.

, 40 The air drawn in by the fan l2 may be conditioned, as for example by being cleaned and moisdirecting air from the chamber 44 between the shells I, 42 to the hair of a person whose head is placed within the hood. The chamber 44 of/ I aperson. Each of the tubes is also preferably connected to its support by means of a ball and socket connection 56 to provide for movement around the axis of the tube to better accommodate the hood to the position of the head of a person whose hair is being dried. A means 66-is provided for regulating the flow from the feeder ducts 26, 2|, in reciprocal proportion, one to the other, to each of the air delivery devices 46 and the tubes 46 connected therewith. The regulating means 66 acts in such a manner that the area for the admission of air to each of the delivery devices 46 and to the tubes 46 associated therewith, whether admission be from one or another of the feeder ducts 26, 2|, or from two of the feeder-ducts, remains constant. One form of regulating means '66 for this purpose is shown in Figs. 1, 3 and 4 and another form or modification in Fig. 5. Referring to the form of regulating mean shown in Figs.' 1 and 3, numeral 62 designates a cylinder in communication with ducts 26, and 2| through

ports

64, 65 of substantially equal area. As here shown, the cylinder is preferably located in the partition wall 61 between the two ducts 26, 2| running side by side. Within the cylinder 62 isa sleeve valve 16 having a port 12 therein the area of which is approximately equal I of the feeder ducts, regulated.

'to the area of one or the other of the

ports

64, 65,

plus one-half of the closed circumference of the cylinder. The sleeve valve, is rotatably, and also preferably axially movable in the cylinder 62. For this purpose thesleeve valve 16 may be carried by a shaft 15. The shaft .15preferably'has a pulley 11 splined thereon, and passing around,

the pulley are pull-cords 66, 6| which pass over suitable idle pulleys 64 and extend through the feeder-ducts alongside of the air delivery devices, in such manner that by. pulling on the cords 66, 6| the sleeve valve 16 may be rotated, and the ad-' mission'of air to the air delivery devices, from one or the other of the feeder ducts, or from both The form and relation of the

ports

64, 65 and12 are such that the sleeve valve 16 in one position will completely shut off communication from one of the feeder ducts, as the feeder duct 26, to the air delivery device 46 and at the same time fully open the air I delivery devicezto the other feeder-duct 2|; in

another position of the sleeve valve 16 the said valve will completely shutoff communication from one feeder duct 2| to the air delivery device and at the same time fully open the feeder duct 26 and establish communication between the feeder duct 26 and theair delivery device; and

in other rotated positions of the valve 16, communication will be established between each of the feeder ducts 26 and 2| and an air delivery device. Depending on the rotated position of the sleeve valve 16 moreor less air will flow through the valve fromone feeder ductthan from the other, and thereby any desired temperature of The sleeve valve 16 is also preferably provided with a skirt 65, the function of the skirt 65 being to close the

ports

64, 65 when the sleeve valve 16 is slid axially. Suitable means are provided for effecting axial movement of the'sleeve valve 16. These means are preferably .of such a nature that axial movement of the sleeve valve 16 to portclosing position is effected automatically with the lifting of the hood from the head of a person. The means for axially'moving the valve 16 is conveniently in the form of a rod 61 carried by the telescoping part 41 of the tube 46. As the hood 46 is lifted the portion 41 of the tube 46 rises carrying with it the rod 61. In the course of the upward movement of the tube section 41, the rod 61 strikes the sleeve valve 16 and thereafter further movement-of the tubesection 41 causes the rod 61 to shift the sleeve valve 16 to the position where the skirt 65 closes the ports 64., 65. In this way failure to shut off the flow of air through an individual hood, when such individual hood is not being used, through the inattention of the attendant, is prevented, the use of air conserved, and the dischargeof unnecessary quantities of heated air into the room avoided.

Th weight of the hood and of the tube part 41 is preferably counterbalanced, so that the hood may be adjusted to, and remain at, a vertical position of use suited to the height of the person whose hair is being dried. Means for this purpose are indicated at 66. The means 66 preferably comprises 'a long spring of the coil type, known in the trade as a pullman type spring.

A strap 62 connects the spring with the tube part 41 and the connection is preferably through a swivel joint 64, so that the tube section 41 may turn without twisting the strap 62. The friction of the counterbalancing spring of the device 66 against its casing, and also the friction between the

tube sections

41, 46 issuch that the tube section will remain in any position to which it is moved against the tension of the spring. The friction is overcome by manual force exercised in raising and lowering the hood, the counterbalancing spring of the device 66 acting with a force substantially equal to that necessary to overcome the weight of the hood andof the tube section 41.

Referring to Fig. '5 an outer chamber 65 is provided within which the air regulating device 66 is located. The chamber 65 has the divided parts 66, 61 and the part 66 is in communication with one feeder duct, as for example, the feeder duct 2| through an opening 66 and the other divided part 61. of the chamber is in communication with the other feeder duct 26 through an opening 66. The port 64 of the'valve 66 opens into the divided part 61 of the chamber'andthe port 65 opens into the divided part 66 of the chamber 65.

In the modification shown -in--I ig. 5 the tube section 41 is acted upon by spring |6| having a force sufllcient to lift the hood 46 and the tube section 41 to the uppermost positions thereof. The

telescopingparts

41, 46 are held in their dif-,

ferent positions of adjustment by means of a friction clamp'or the like I66. In adjusting the hood to the head of a sitter the hood is pushed down to the desired position against the force of the spring Ill, and then fastened in said adjusted position by operation of the clamp I66. If the drying operation has been completed the clamp I66 is loosened whereupon the spring l6| raises the hood to its upper position, and during such movement, the .rod 61 mounted on a tele- 75 air-delivery devices, and means for regulating the scoping part 41 comes in contact with the sleeve valve 10 and slides axially to a position where the skirt 85 thereon closes the ports ll, 85.

A yent I may be provided in the cylinder 62, and by suitably choosing the size of the vent, the rate of moving and stopping of the hood 4. may be regulated in the end part of the movement thereof.

To facilitate the manufactureof multiple service hair-driers with variations in the number of air-delivery devices according to the wants of diflerent customers, the device preferably comprises a number of units I05, one of which is shown in Figs. 3 and 4. Each of these units includes short sections of the feeder-ducts, 20, 2!, a means 60 for governing the flow of air to a hood or delivery device In, and a tube section 48; a delivery-device 40 may also be included as a part of the unit. In-constructing a multiple drier, the central blower and a number of units I corresponding to the: number of air-delivery devices desired are shipped and the apparatus set up by connecting the units lli with sections of tubing llll which can be cut of a length'to give the desired spacing between the air delivery devices, and the units I05 and sections I" joined by a slip joint and held together in any suitable manner.

The invention may receive otherembodiments than those herein specifically illustrated and described.
