13 Claims.

My invention relates to drying apparatus, and has particular reference to apparatus forusein drying hair or the hands, or the like, and a principal object of my invention is to provide a newy on the line 1-1 of'Figure 3, and showing onev characteristic operation of the apparatus,

Figure 2 is a similar horizontal sectional view of said embodiment showing another characteristic operation of said apparatus,

Figure 3 is a side elevational View of said embodiment, portions of the pedestal being broken away, while Figure 4 is a transverse vertical sectional view, taken on the line 4 4 of Figure 2.

l The embodiment of my invention herein shown comprises a dome-shaped housing, or casing 5, having a beaded front edge 6, tapering toward the rear, and terminating in a rear wall 7 having an opening 8 surrounded by =a ange 9, and also having an opening 10 surrounded by a flange Disposed within the housing, or casing 5 is an insert comprising a dome-shaped shell 12, at its rear 4end provided with a tubular extension 13 extending through the flanged opening-10, extending in substantially parallel spaced relation with respect to the housing 5 and terminating short of the forward extrem-ity of said housing, denning a passage 14, and at its forward end supports v the forward portion, as by an integral connection, of a dome-shaped hood member .15, forming a chamber 16, extending in spaced relation with respect to the shell 12 and dening therewith a passage 17, communication .being afforded between the chamber 16 and passage 17 by a plurality -of annularly arranged apertures 18 covered by a strip of screen 19 secured by rivets 20 to the hood member 15. A web 20 of screen is disposed to span the space between the forward portions of the shell 12 and housing 5, being secured in position by screws 21. Disposed at the rear of the housing 5is a circular block 22 of material, provided with an opening 23 surrounded by a boss 24, and with an open- .ing 25 surrounded by a boss 26, the boss 24 extending into the ange 9 surrounding the opening 8, and the boss 26 extending into the tubular extension 13, the block being scured in position by a plurality of pins, only one of which is shown, as at 27. Cooperating with the block 22 y is a cup-shaped supporting member 28 into which the block 22 is rotatably seated, and rotatably se- 5 cured by a rivet 29, limited in rotation by a pin and slot arrangement 30, the supporting member 28 having an opening 31 surrounded by a boss 32 and an opening 33 surrounded by a boss 34, the openings 31 and 33 being so located as to come 10 into registry with the openings 23 and 25 of the block 22, a washer 35 being interposed between the block 22,and supporting member 28 and secured to the latter by any suitable means, and provided with openings registering withthe openl5 ings 31 and 33. 'I'he supporting member 28 is also provided with oppositely disposed radially extending studs 36 accommodated in the end portions of furcatons'forming part of a supporting pedestal 37. 20

Secured to the rear oi the supporting member 28 is a circulating unit comprising a fan casing 38 enclosing a centrifugal fan 39 of the turbine type mounted upon the armature shaft 40 of a motor 41 secured to the casing 38 by bolts 42, the axis 25 of rotation of the fan 39 being arranged substantially at right angles to -the axis of the housing 5, and communicating with the'v eye of the fan 39 and forming part oi.' the fan casing 38 is -a curved conduit pipe 43 the open end of which 30 seats about and is secured to the boss 32 surrounding the opening 31 in the supporting member 28, and also formed as a part of the fan casy ing 38 is a conduit 44 arranged in line with the circumferential periphery of the fan 39, and hav- 35 ing its outer end fitted over and secured to the boss 34 and communicating with the opening 33 in the supporting member 28. Disposed within the conduit 44 is a heating coil 45 insulated therefrom, and secured in position by suitable secur- 40 ing means as indicated at 46. VWhen the motor 41 and Ian 39 are energized and assuming the apparatus to be in the position shown in Figure 1, pressure isreduced in the passage 14 causing movement of air through the 45 opening 8 into the conduit 43 and thence to the l fan 39 which discharges such air outwardly through the conduit 44 and into the passage 17,

passing thence into the chamber 16 through the openings 18, over the head of the subject treated, and Vcoming into the zone' of low pressure at the open endo! the passage 14 a material part of such air is entrained, enters such passage and is recirculated, as clearly shown by the arrows in Figure 1.

To reverse circulation of air through the apparatus the casing may be grasped by the operator and rotated as permitted by the rotatable connection of the block 22 with the supporting member 28, to bring the openings 8 and 23 into alinement with the conduit 44, and to bring the openings 13 and 25 into alinement with the conduit 43, wherefore air will be circulated as indicated bythe arrows in Figure 2, air entering the chamber 16, passing through the apertures 18 into the passage 1'1 thence through the tubular extension 13 and conduit 43 to the Ian 39 being then discharged into the extension 44, heated, thence discharged into the passage 14 and outwardly, and by reason ofthe air of low pressure in the chamber 16 a material portion of this same air again enters the chamber 16 and is recirculated.

Thus it is apparent that the directionof recirculation of the air passing through the apparatus may be reversed at will by a simple operation, and more rapidv and eiiicient operation etfected, with a material gain in heat energy conservation.

It will be apparent that the embodiment herein described accomplishes the principal object of the invention, and is adapted for uses and purposes not herein particularly referred to, and.

may be variously changed and modiiled without departing from the spirit oi my invention, and accordingly it will be understood that such embodiment is illustrative only and my invention is not limited thereto.
