' 1o Claims- (Cl. ca -zc) This invention relates to adrier and particularlyto a drier especially adapted tor use in drying thejhair and scalp, such drierabeng ordinarily found in beauty shope. barber shops and similar places, although, of course, susceptible of advantageous use in a number ci' other places.

it may he broadly stated that there are two` general types oi driers ci this character inv use end the advantage .or utilizing fresh air throughout the drying operation. l

The recircnlating type of drier operates on a digerent 'principle from the direct type in that substantially the same air is circulated over and over again within the hood oi the lirici-Ln The advantage of the recirculating type. ,oi drier resides in the aot that the heir oi the persm being treeted is dried from the eclil outwardly toward the outer ends of the hair. However, the reoiroulated air in this type ci drier he comes 'Saturated vsrith.` moisture and .the 'time required for the drying operation is thereby inaterially increased.

The main object of the presenilnventions ie to provide a drier of the character specied which will dry the hair from the scalp outwardly, as in'tlie reclrculating type ol drier above mentloned, and will also use fresh air throughout the drying operation as in the direct type ofv drier.

Another object or the mventiqnls'tn provide'.

a drier which is "so constructed l ,fresh dry air will be the active drylns medium throughout the drying operation A iurther object of the invention is to provide a'. drier in which the circulated air will be iree from dirt and foreign cubeta-mes. a8 well as irae from moisture; Y

A more specific object of the invention is to provide a-drier wherein the air is drawn into and. dlschaleed from the drier at a point remote from the open end oi the hoodv of the drier.

A further object of the invention is to Provide a drier wherein the path vof the circulated air is inwardlyv of the drier from adjacent the rear end thereof. forwardly therethrough t a point adjacent the open. end oi the hood, then `rearwardly therethrough and out to atmosphere at a point remote from the open end the Another object is to. provide a drier which is of simple construction. is emcient in operation,

and has the necessary facilities for all the ad justments required in actual use.

Additional and further objects of the invenl tion will be pointed out hereinafter during the following detailed description of an embodiment of the invention. which is illustrated in the acconocerlos drawinss. wherein,

in describing the drier shown in the several views of the drawings, the corresponding parte oi the drier will loe designated by the same reference characters throughout the @fr viewt.

The drier includes three main parte, namely, a head or drier portion i8, a supporting standard il. and 'a base or pedestal in., The head or drier portion i@ comprises o.v main casting it forming the support for the operative parts of the head and havingr a.v reduced annular portion i3d and an enlarged substantially conical portion ith. me portion i3d oi' the casting i3 is provided with a rearwardly facing (that is toward the left as viewed in Fig. 3) substantially conical recess id into which extend a phlrality oi circumierentially paced ribs" lo havlnir openings therein through .am Project ediustable supporting bolts le for 'en electric motor n, it beine noted niet sale y be accurately centered-'in the recess7 :it .te ne 'ns of the belts is.

The. hinter il beine supported at a. plurality of clrcniferentiallyseparated points and in spaced' lfeltloh to the conical wall of the recess i4, it will heleen that a. substantially emular unob- 'et'rticted 'passageway lla is provided between the :noto: and the casting I3, such passageway comat its left-hand end. (as viewed in Fig. 3) ,"Wlth'the enlarged portion of the conical recess Hand at its right-hand; end with the interior of to a. base 56. The tubular member 56, as will be understood-is adapted to be raised and lowered in the tubular member 51 in order to vary the verticalvheight of the drier and the location of the l drier head. Secured to the tubular member 56 is a spring-pressed latch 59 and a vertically extending member 66, such member being stationarily mounted with respect to the tubular member 56 and having a series of openings 6| along one of its edges and adapted to receive the latch mem- ,ber 59, whereby, when the latch member is in engagement with any one of the,l openings 6|, the tubular member 56 will be supported in whatever position of vertical adjustment it may be in. A member 62 extends parallel with the member 60 and is provided with a plurality of snubbing projections 63 which are upon the edge of the member 62 corresponding tothe edge of the member 60 in which the recesses 6| are formed, such the latch 59to push said latch out of engagement with the recesses 6|. The member 62 has an extension 64 at its lower end that is articulated to a lever B5 pivoted at 66 and provided with a foot engaging portion 61 extending through an opening in the base 58, whereby when the portion 6i is depressed the member 62 will be elevated and thelatch 59 moved out of engagement with the particular opening 6| with which at the time it is in engagement. Surrounding the extension 64 is a spring 68 which at one end abuts against a partition wall 69 of the base 58 and at its opposite end abuts against a collar lil secured upon the i extension 64, and thus the member 62 is normally maintained in its, lowermost position and the foot engaging portion 61 is -held above the base 53 in position to bedepressed by the foot of theV operator.

In using thev drier, the operator depresses the portion Si to enable the tubular member 5S to be moved upwardly or downwardly within the tubular member 51 to adjust the'drier head to the proper height, after which the portion 61 is allowed to return to its normal position and the latch 59 will engage in the adjacent opening 6| of the member 66 and-hold the tubular members 56 and 5i in the relative positions to which they have been moved. The operator may then adjust the drier head angularly to properly position thev V same with respect to the head of the person being treated, such adjustment being eected by rotating the knob 45 in the proper desired direction. It being assumed that the lter 50 is in position in the drier, the operator then manipulates the

switches

46 and 47 to eiect the heating of the elements 33 and the operation of the motor Il. The rotation of the motor I1 rotates in turn the compound fan, and the blades 3| forming the Y 'i outer fan draw air into the drier head through the openings 53 in the cover plate 5 I, through the groove I8 and the .openings 20, and into the compound fan between the sleeve-like portion |30 of the casting and the blades 3|, as clearly indicated by the arrows in Fig. 3. The air then passes radially outwardly of the compound fan between the blades 3| of the. outer ian and through the recess I8 in the portion |3b' of the casting, from whence it passes overthe heating elements 33 and into the hood member. 2| exteriorly of the inner hood member 35, such movement of the air being also indicated bythe arrows in Fig. 3. The air Adrawn into the drier head by the blades 3| of the compound ian is theniorced in a whirling convolute path through the outer hood member 2| and around the exterioof the inner conical hood snubbing projections engaging with a portion of member 35. vThis whirling path of the air is gradually conned to a narrow passageway due to the increased diameter ofthe inner hood member 35 toward the open end of the drier head until the air passes between the cylindrical portion 36 of the inner hood member andthe outer hood member and into. the reentrant conical flange portion 22 of the outer hood member. The reentrant conical iiange portion 22 acts as a baille andtdeiiects substantially all of theair into the inner hood member 35. Since the ian blades 25 are oppositely disposed with respect to the blades 3i, the rotation of the blades 25 acts to draw air in through the open end of the drier head and to force the same toward the rear of the head. This action of the blades 25, therefore, draws the air which has been deflected by the ange portion 22 of the` outer hood member into the inner hood member rearwardly through the inner hood member, in whirling paths and through the sleeve 29 and passageways Ma surrounding the motor il, thence outwardly through the recess i4 and' the openings 55 in the cover plate 5|, as clearly indicated by the arrows in Fig. 3.

The effect of the air currents set up within the drier head upon the head of the person being treated is such that the hair of the patient is drawn away from the scalp and is uied or ruiiled, thus allowing the moisture to be drawn therefrom from the scalp outwardly to the hair and to be carried thro h the drier head and discharged out of the nings 55. As soon as the air passing over the elements 53 is heated there will be, in addition to. thedrawing action oi' the air, a heating action upon the hair, thus 3 speeding up the time required for the drying operation. It will be noted that since `all or the incoming air must pass through the iilter 5U the air will be cleanv and free from foreign substances and that, since the air which absorbs the moisture is discharged from the drier so as not to mingle with the incoming air, there is no likelihood of the circulated air within the drier becoming saturated with moisture and clean free air will be moving through the drier at all times during the drying operation.
