Description

June 24, 1930. E. A. MCGINNIS HAIR DRIER Filed Jan 14, 1929 INVENTOR Patented June 24, 1930 UNITED STATES PATENT oFFicE EDWARD A. MOGINNIS, OF PITTSBURGH, PENNSYLVANIA 'HAIR DRIER Application led January 14, 1929. Serial No. 332,476.
My invention relates to hair driers of the type utilizing blown heated air as a drying medium.
The primary object of the invention is to provide a hair drier of the character described, in a manner as hereinafter referred to, which embodies novel means for selec-l rangement, durable and highly efficient in Y its use, compact, adjustable and comparatively inexpensive to manufacture and operate; e
With the foregoing and other objects in View which will appear as the description proceeds, theJ invention resides in the com' bination and arrangement of parts and in the details of construction hereinafter de-y scribed and claimed, it being understood that changes in the precise embodiment of the invention hereinafter disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.`
In the drawing wherein like numerals of reference designate corresponding parts throughout the several views:-
Figure 1 is a vertical cross sectional view of a hair drier constructed in accordance with the invention.
Figure 2 is a fragmentary front` View thereof.
Figure 3 is an expanded plan view of the air regulating slide.
Figure 4 is a transverse ycross sectional view of the regulating slide and the associated slide guide.
Figure 5 is a front view of the conduit member.
Figure 6 is an enlarged sectional view of the conduit on line V-V, Figure 1.
Referring in detail to the drawing 1 denotes a substantially heini-spherically shaped confining dome having its top provided with dome l, and is provided with an adjusting vertically extending, centrally disposed tubular heat inlet neck 2. A heat distributor 3 is mounted in the confining dome 1. The heat distributor 3 extends parallel to the inner side of the confining-dome 1 and is spaced from the latter to provide a heat chamber 4 having an open lower end. The heat'distributor 3 is fixedly supported in position by a plurality of inter-connecting spacing pins The confining dome 1 with its associated distributor 3, is adapted for being positioned on the head to completely cover and enclose the hair upon the latter during the halr drying operation.
rlhe heat distributor 3 is formed with a plurality of semi-round apertures 6 and with elongated slots 7, which communicate with the heat chamberfl and provide passages for the heated air from the latter to the hair. The straight wall of each of the apertures 6 carries a lip 8 which inclines into the heat chamber 4 at a proper angle to direct the heated air from the latter through the apertures 6.
A tubular heat conduit 9 is detachably fixed, by a set screw 10, or in any other suitable manner, to the inlet neck 2,` and conducts the heated air from the source of supply to the heat chamber 4.
A quadrant regulating slide 11 is positioned against the inner side of the confining dome 1. The regulating slide 11 is shiftably mounted for vertical adjustmentvin a vertically extending slide guide 12, which is disposed in the heat chamber 4 and fixed to the inner front side of the confining dome 1. j
The regulating slide 11 is curved to conform to the curvature of the confining dome 1 and is provided with a screw bolt 13 which is fixed to the lower end thereof. The bolt 13 projects through an elongated, vertically disposed slot 14 formed in the confining nut 15 which seats against the outer side of the confining dome 1.
The regulating slide 11 is shifted in the slide guide 12, to the position desired by forcing the adjusting nut 15 upwardly or 100 downwardly along and on the slat 14. The
regulating slide 1l is locked in position by the adjustment of the nut 15 upon the screw bolt 13 to engage the confining dome 1. As the screw bolt 13 extends through the slot 14, the length of the latter necessarily determines and limits the distance of travel permitted in the adjustment of the regulating slide 1l.
The purpose of the slide 11 is to regulate the opening 2', in the inlet neck 2 so as to direct the heated air to the hair at any part of the head required.
The adjustment of the regulating slide 11 shifts the latter along and against the lower end of the opening 2, in the inlet neck 2. The regulating slide 11 is formed with a transversely disposed opening 16 and with a pair of longitudinally extending, transversely aligned openings 17. The opening 16 has an area commensurate to one-half the area of the opening of the inlet neck 2, and is spaced from theupper end of the regulating slide 11 by the end portion 18. rlhe pair of openings 17 are positioned below the transverse opening 16 and are separated by the division strip 19 disposed therebetween.
When the regulating slide 11 is in its lowered position, as shown inFigure 1, the upper end thereof clears the openin 2', in the inlet neck 2 and no portion oi the latter is closed by the regulating slide 11. By shifting the regulating slide 11 upwardly until the upper end thereof extends across the center of the inlet neck opening 2, the front half of the latter will be closed and the rear half thereof will be open, thereby directing all of the heated air toward the hair at the rear of the head. By further shifting the regulating slide 11 upwardly until the end portion 18 closes the rear half of the inlet neck opening 2, the heated air will pass through the transverse opening 16 and be directed to the hair at the front of the head. Upon still further upward movement of the'regulating slide l1, the pair of longitudinally extending openings 17 will be brought into registration with the inlet neck opening 2. The heated air currents passing through the latter will strike the division strip 19 and will be deflected to pass through the pair of openings 17 to the hair at both sides of the head. In shifting the regulating slide 11 upwardly to the limit permitted by the engagement of the screw bolt 13 in the slot 14, the inlet neck opening 2 will be covered and closed completely by the regulating slide 11 to prevent the passage of the heated air therethrough.
The conlining dome 1 is provided with suitable designations 20 indicating to the operator, the exact adjustment positions of the regulating slide 11. The designations 2O are disposed adjacent to the slot 14 and with correspondingly positioned apertures 23, and the rotatable adjustment of the sleeve valve 21 effects the closure and opening of the conduit apertures 23.
The sleeve valve 21 is provided to dissipate the heated air when not required or -to reduce the temperature of the conduit 9 when the latter is closed. The sleeve valve 21 further functions to admit cold air to the heated air in quantities to most eiliciently eli'ect the drying operation.
The conduit 9 is provided with a flexible ball and socket connection to facilitate the adjustment of the device to the head. The portion of the conduit 9, adjacent to the confining dome 1, is expanded to form a ball member 24. The adjoining end of the conduit 9 is likewise expanded to form a corresponding socket member 25, which overlaps the ball member 21. The socket member 25 is provided with a plurality of vertically extending slots 26 which are open at their lower ends. The ouler periphery of the socket member 25 is formed with screw threads 27, which are engaged by a knurled clamping ring 28. (lwing to the open slots 2G, the adjustment of the clamping ring 2S on the socket member 25 will compress the latter to establish the proper engagement between the ball member 26 and the socket member 27.
A pair of shutters, respectively indicated at 29 and 30, is mounted in the passage of the conduit 9 adjacent to the latter-s connection with the inlet neck 2. The shutters 29 and 30 are semi-circular in contour and have a combined area commensurate to the transverse area of the conduit 9.
The shutters 29 and 30 are hingedly connected to a common shaft 31, which extends diametrically through the conduit 9. The shutter 29 is provided'with a hinge extension 32 which extends through a circumferentially disposed slot 33 formed in the conduit 9. The shutter 3() is likewise provided with a hinge extension 34 which extends through a circumferentially disposed slot 35 formed in conduit 9.
Each of the slots 33 and 35 extend approximately one-quarter distance around the conduit 9 and are diametrically opposed relatively to each other. The hinge extensions 32 and 3l, extend through and are pivotally journaled in a knurled bearing band 3G, which surrounds the conduit 9 and covers the slots 33 and 35.
The outer ends of the hinge extensions 32 and 34 carry fixed operating knobs, respectively indicated at 37 and 38 for adjusting the respective shutters 29 and 30. Each of the operating knobs 37 and 38 is provided with a set screw `39 which is adapted to engage the bearing band 36 for securing respective shutters 29 and 30 in the adjusted position.
The shutters 29 and 30 normally depend in the open position, as shown in Figure 1, and may be independently adjusted to any position by the manipulation of respective operating knobs 37 and 38. The slots 33 and 35 allow the shutters 29 and 30 to be drawn around to any desired position by the circumferential adjustment of the bearing band 36 upon the conduit 9.
By the adjustment of the shutters 29 and 30, the passage of the conduit 9 may be completely or partially closed or opened, or the front half, rear half, or either side hal-f of the said conduit passage may be opened or closed, as the provision of the slots 33 and 35 permit of the shutters 29 and 30 being drawn from one diametric position to another disposed at right angles to the latter.
This universal and independent adjustment of the shutters 29 and 30, provides effective means for controlling, diffusing and distributing the yheated air currents to most efliciently effect. the hair drying operation.
The set screws 39 are preferably mounted in respective knobs 37 and 38 to dispose same in a direction conforming to the flat' plane of the shutter 29 or 30 associated therewith. By this arrangement, the operator can readily determine the exact disposition of the shutters 29 and 30 by noting the positions of the set screws 39.
While this invention is primarily intended for drying hair, the same is also admirably adapted for steaming the latter. For this purpose, the confining dome 1 is provided with a steam inlet valve 40, which is preferably disposed adjacent to the lower end of the former. During the steaming operation the inlet neck opening 2 is closed by the regulating slide -11 to prevent en trance of steam to the conduit 9.
The present invention combines a construction providing a most efficient device of its kind, which is conveniently operable to dry hair uniformly and expeditiously.
What I claim is:
