HAIR DRIER Filed March 7, 1945 2 Sheets-Sheet l Patented Mar. 9, 1948 UNITED STATES PATENT OFFICE HAIR. DRIER Albert G. Thomas, Alexandria, Va. Application March 7, 1945, Serial No. 581,363
Claims.
This invention relates to beauty shop equipment and particularly to hair driers which are widely used for conditioning the hair of patrons following shampooing, oil treatments, permanent waves, etc. The present invention embodies several distinct improvements and advantages over contemporary apparatus for such purpose.
One of the objects of my invention is to provide a hair drier operable through adjustable hot and cold air cycles. thus avoiding excessive heating of the scalp and resulting from continuous heat application and variable to suit the requirements of the individual.
Another object of my invention is to provide a hair drier having a dual air pressure and air suction circulating system.
Another object is to provide a hair drier having sound deadening means in the air passage to the helmet, for lessening fatigue.
An additional object of this invention is to provide a hair drier of increased efficiency by reason of the proximity of the air inlets to corresponding air outlets, thus providing a local drying at a number of individual'areas.
Other objects and advantages of this invention will be apparent from the following description and taken in connection with the drawings in which:
Figure 1 is a vertical sectional view of form of my invention;
Figure 2 is avertical part sectional view of a hair drier generally similar to that shown in Figure 1 but having the inlet and exhaust fans mounted on the same shaft and driven by a common motor. I
Referring now to the drawings and first, to
one
' Figure 1, a frame generally indicated at I includes a. lower housing 2, a hollow, upright conduit 3 and a pair of hollow upper arms 4 and 5 serving as inlet and exhaust passages respectively for the drier helmet generally indicated at 6. An electric motor I suitably mounted in housing 2 rotates fan 8 to draw air in through apertures 9 and III of the housing, thence through ports H and I2 in a horizontal wall l3 and drives the same through a transverse layer of porous, sound-insulating material l4 into the hollow conduit 3. This material may consist of loose asbestos, rock wool, shredded wood. or the sound filter may consist of battles. Worm la is fastened coaxially to the shaft of motor I and drives gear l to having projecting face pin i6 and which gear is supported for rotation by coaxial bearing pin lib fastened to support It. Pin l6 operates in slot ll of a lever I I pivoted at I! to support I! and moves valves 28, 21 alternately up and down to open and close ports II and i2, respectively. Heating element 22 is positioned in a lower compartment defined by the wall of housing 2 and an inner preferably heat-insulating wall 2a and is electrically energized through connections as shown. Thus, alternate charges of warm and relatively cool air will be forced into the inlet arm 4 and helmet 6. This tends to prevent overheating of the subject. A motor and fan assembly 23 is suitably mounted in the lower portion of upper arm 5 and draws air through the porous sound insulator or baflie 24 and then forces it to the outside through opening 25. Insulator or baiile- 24 contributes to the external as well as internal quiet operation of the drier unit while exhaust fan 23 increases the circulation with little increase in operating cost. The sound filters l4 and 24 also reduce sound resonance effects.
Helmet or head piece I, it will be observed, is comprised of a dome-shaped outer wall 26 in communication with inlet arm 4 and forms with a similarly shaped inner'wall 21 a circulating inlet space 28. Wall 21 is formed of rigid material such as metal or plastic, but may be of soft material such as cork or rubber. Its inner surface is formed with inwardly projecting truncated cones 29 which are apertured to communicate with space 28. Upper arm 5 also communicates with the interior of the wall 21 to draw the air therefrom. Suitable air sealing means such as a rubber ring may be used inside wall 21 and surrounding the head of the patron if desired. It will be observed that the conical projections 29 serve to space the helmet from the head of the wearer and by reason of the inflow of air at these points a "floating" and not at all uncomfortable support for the head will be provided. In fact the device may be inclined so that the subject's head will rest upon the supports 29, being partially lifted by the incoming air. The depressed portions 29a allow the air to be withdrawn through the hair and out hollow arm 5 from which it is carried through passage 25 by fan 23.
necting with said relatively cool air chamber, a pair of valves for periodically and alternately closing said openings, means in said heated air chamber for heating air, and means driven by at least a part of said blower-driving means for actuating said valves to distribute to said first blower alternately said heated air and said relatively cool air.
4. In a hair drying device, a headpiece, a blower for moving air-to said headpiece, a duct to direct air from said blower to-said headpiece, a motor to drive said blower, casing means for said blower having port means therein for flow of heated air therethrough and having other port means therein for flow of relatively cool air therethrough, a valve for periodically reducing flow 0! said heated air through its port means, another valve for periodically reducing flow of said relatively cool air through its port means, means for heating air to pass through said first named port means, said device including a pivoted member to support said valves, and means associating said motor with said pivoted member to cause rocking thereof to cause said valves to admit alternately to said blower heated air and relatively cool air.
Therefore, I desire the same to be limited only by the subjoined claims.
I claim:
1. In a hair drier, a headpiece, a blower for moving air to said headpiece, a motor to drive said blower, a duct to direct air from said blower to said headpiece, partition means having an opening therein iorheated air and an opening therein for relatively cool air on 'the intake side or said blower, means for heating air in a chamber formed by said partition means and connected with said heated air opening, a pair of valves for periodically closing said openings, and means driven by said motor for actuating said valves for alternately distributing to said headpiece heated air and relatively cool air.
2. In a hair drier, a headpiece, a blower for moving air to said headpiece, a motor to drive said blower, a duct to'direct air from said blower to said headpiece, partition means having an opening therein for heated air and an opening therein for relatively cool air on the intake side of said blower, means for heating air in a chamber formed by said partition means and con nected with said heated air opening. a pair of valves for periodically closing said openings, and means driven by said motor for actuating said valves for alternately distributing to said headpiece heated air and relatively cool air, said valveactuating means including means for adjusting said valves to vary the ratio of heated air to relatively cool air supplied to said duct.
3. In a hair drier, a headpiece, a first blower to move air to said headpiece, a duct to direct air from said first blower to said headpiece, a second blower to move air away from said headpiece, another duct to direct air from said headpiece to said second blower, means for driving said blowers, partition means on the intake side of said first blower forming a chamber for heated air and a chamber for relatively cool air and havperiodically reducing flow of said relatively cool.
air through its port means, means for heating air to pass through said first named port means, and means associating said motor with said valves to actuate said valves to cause distribution to said blower alternately heated air and relatively cool air.
