IPATENTEDJULI? 1191a SHEET 3 OF 3 1 FACIAL TREATMENT APPARATUS This invention relates to a skin treatment apparatus of the skin to remove extraneous matter from the surface and pores of the skin. I
Another object is to provide an apparatus, of the type described, having electrically operable steam generating means, an electrically operable air mover, a substantially rigid applicator on the end of a flexible conduit, and control means for connecting the outlet of the blower to the conduit to permit mixing of the steam with the air being moved by the air mover and being delivered to the applicator by the conduit and alternately for connecting the inlet of the blower to the conduit whereby the pressure in the applicator is reduced.
Another object is to provide an apparatus, of the type described, which has means for controlling the rate of delivery of air to the conduit. I I

FIG. 5 is a partly sectional view taken on line 5-5 of FIG. 2;
FIGS. 6, 7 and 8 are sectional views taken on lines 6-6, 7-7 and 8-8, respectively of FIG. 3; and,
FIG. 9 is a diagrammatic illustration of the electric control circuit of the apparatus.
Referring now particularly to the drawings, the facial or skin treatment apparatus 10 of the invention includes a substantially rectangular base plate 12, which is supportable on a flat surfaceby a plurality of feet 13 provided with upwardly extending threaded studs 14 which extend through suitable apertures in the base plate and are secured thereto by nuts 15 and washers 16.
A housing 18 is mounted on the front portion of the base plate and is secured thereto by means of screws or bolts 19 which extend through suitable apertures ofthe base plate into downwardly opening threaded bores of the bottom wall 21 of the. housing 18. The housing 18 for clarity of illustration has been shown as a single piece formed of a plastic or other substance having low heat conductivity but in practice may be formed of several sections which are bonded or otherwise secured to one another.
The housing provides a steam generating chamber 22 which extends the full length ofthe housing and is defined by a bottom wall 21, front and rear vertical walls 24 and 25, end walls 27 and 28 and a horizontal intermediate wall 29. The rectangular chamber 22 may be filled with water through an aperture 31 in the front portion of the intermediate wall 29. A tubular neck or filler member 32 is secured to the top surface of the wall 29 by an adhesive, bonding agent or the like. A
closure cap 33 is telescopical over the filler member 32 and is held thereon by frictional engagement therewith. The bottom wall may be provided with a threaded drain aperture which is closed by a plug 34.
The water in the chamber 22 is heated by the passage of current through the water from one plate electrode 35 toa second plate electrode 36 spaced and insulated .from the electrode 35. The electrodes are mounted by suitable electrically insulating blocks 37 and 38 and screws 39 and 40 to the housing bottom wall 21. The
.terrninals on the ends of the two conductors 41 and 42 of a two conductor cable 43 are secured to the electrodes 36 and 37 by rivets. The cable extends through a suitable aperture in the side wall 25 and a suitable .grommet or other means may be used to seal between the side wall and the cable. The insulation of the cable, of course, is water proof.
' The housing above the horizontal wall 29 provides three chambers 51, 52 and 53 which are defined by the upper portion of the rear wall 25, an upwardly and rearwardly sloping wall 54, a top wall 55, the upper portions of the side walls 27 and 28 and two partitions 57 and 58. The steam or water vapor generated in the chamber 22 may flow upwardly to the chamber 51 through a port 60 in the intermediate horizontal wall 29 and from the outer chamber 51 to the middlechamber 52 through aport 62 of the partition 57. The partition I telescoped on the shaft and rigidly secured thereto in any suitable manner as by means of set screws.
A turn wheel is rigidly secured to the shaft exteriorally of the housing for rotating the shaft to cause the valve members to selectively open and close the ports 62, 64 and 65 as will be explained below.
A cam 81 is also rigidly secured to the shaft, between the end wall 28 and the wheel 80. The peripheral surface of the cam is engaged with the rollers 82 and 83 mounted on the resilient arms 84 and 85, respectively, of switches 87 and 88, respectively. The contacts 89 and 90 of the switches 87 and 88, respectively, are normally in the positions indicated in FIG. 9 when the rollers are in the positions relative to the cam 81 illustrated in FIG. 2. The contact 89 moves to its closed position when the shaft is rotated to move the recess 91 of the.
connection of the electrodes across an input circuit and the switches 87 and 88 control the energization of an electric motor 102.
The upwardly sloping wall 54 of the .housing has a port which opens to the middle chamber 52 and a tubular socket 104 is mounted, as by a bonding agent, an adhesive or the like. The reduced tubular portion 105 of a fitting 106 is insertable in the socket and has one end of a flexible conduit 107 connected thereto. The free end of the conduit is provided with a tubular fitting or socket 110 into which is insertable an applicator 112. The applicator 112 is tubular and has a substantially oval end surface 113 which is adapted to slide or glide over the skin. If desired, the end surface 113 of the applicator may be provided with grooves or serrations for a purpose to be described.
The electric motor 102 is secured to a suitable mount 115 which is in turn secured to the base plate by the screws 116. A blower or air mover 120 is rigidly secured to the drive shaft 121 of the motor, the drive shaft extending through a central aperture in the inner circular side plate 122 of the air mover and secured thereto by a nut 123 threaded on the drive shaft on opposite sides of the side plate. The air mover includes an outer circular side plate 125 which has a central aperture 126 and a plurality of arcuate'veins 127 which curve outwardly from their inner ends at the edge of the aperture 126 to the periphery of the side plates.
It will be apparent, of course, that as the air moving means is rotated in the direction indicated by the arrow in FIG. 5, air will be drawn inwardly through the aperture 126 and expelled outwardly at the periphery of the blower. The inlet aperture of the air mover is in communication with the chamber 53 through an inlet conduit 130 secured in a suitable aperture 131 of the housing rear wall 25 whose rear end extends into an adaptor 134 mounted on a bracket 135 secured to the base plate by screws 136. The bracket of course is provided with an aperture through which the inlet conduit 130 extends into the adaptor. The adaptor 134 may be secured to the bracket 135 by screws or the like and has a reduced portion of substantially the same diameter as the diameter of the inlet aperture 126 and projects inwardly therethrough.
It will therefore be apparent that as the air mover or blower is rotated, the pressure within the chamber 53 is decreased and air is moved outwardly at the periphery of the blower. A portion of the air being moved by the blower is directed to a conduit 140 whose inlet end is in alignment with an aperture 142 of a bracket 143. The conduit 140 is secured to the bracket by means of its flange 144 and screws 145. The other outlet end of the conduit 140 is secured to the housing rear wall 25, at the location of an aperture or an inlet port 146 of the rear wall which opens to the chamber 51, by its flange 147 and screws 148.
- It will thus be apparent that the blowerwill tend to move air into the. conduit 140 and thence through the conduit 140 into the chamber 51. i
A cover 150 is secured to the base plate by means of angle brackets 151 secured, as by welding, to the base plateand screws 152 which extend through suitable apertures in the front and rear wall portions 153 and 154 of thecover. The rear wall portion is providedv with slots 155. The particular configuration of the cover may be varied as desired to provide a desired ornamental appearance to the apparatus. The cover at its front portion has a window or opening 156 at the location of v the upwardly and rearwardly sloping wall 54 of the housing 18 and an ornamental plate 156, secured to the wall 54, closesthe window. The plate is provided with suitable apertures at the locations of the wheel 80, the socket 104 and a wheel 160 of a rheostat or variable re sistance 162. The rheostat 162 is mounted on a bracket 164 whose lower end is rigidly secured to the base plate by means of screws 165.
Referring now particularly to FIG. 9 of the drawings, the conductors of the two conductor cable 43 terminate at the usual plug 166 by means of which the conductors may be connected to opposite sides of an electric supply system. The electrode 36 is connected to the conductor 42 by a conductor 117 while the other electrode 35 is connectible to the conductor 41 through the conductors 168 and 169, the switch contact 89 when it is moved to its closed position engaging its stationary contact 93 and a conductor 120. The motor 102, when the movable contact 90 of the switch is in the position illustrated in the drawing engaging its stationary contact 94, is connectible across the conductors 41 and 42 through the conductor 170, the movable contact 89 of the switch 87, the conductor 171, the resistance 162, the movable contact 172 of the rheostat, the conductors 168 and 169, the switch contact 87 and the conductor 120. When the switch is moved to its other opposite position wherein its movable contact engages the stationary contact 95, the motor is connected directly across the conductors 41 and 42 by the conductor 170.
It will be apparent that the speed of operation of the motor, and therefore the speed of rotation of the blower, will vary in accordance with the'value of the resistance 162 as determined by the position of the movable contact 172 thereon and therefore the speed of the motor may be varied by adjusting the position of the movable contact 172 by means of the wheel 160.
When the skin of an operator is to be treated by use of the apparatus 10, the chamber 22 is filled with water through the filler 32 and the closure cap 33 is then placed on the filler member 32. v
The fitting 106 of theflexible conduit 107 is then inserted into the socket 104 and an applicator 112 is inserted into the socket at the free end of the conduit. The wheel 80 is then rotated from the of! position to the mist" position. As the shaft 71 is thus rotated, as seen in FIG. 2, in a counter-clockwise direction to the position wherein the cam recess 96 of the cam 81 moves into registry with the foller 83, the normally open contact 89 of the switch 87 moves into engagement with its stationary contact 93. As a result, electric current will now flow through the water in the chamber 22 between the two electrodes 35 and 36 heating the water and causing it to boil and evaporate. Simultaneously, the motor 102 is energized so that the air mover is now rotated. v I
This movement of the shaft 71 causes the. valve member 74 to be rotated upwardly to the open position illustrated in broken lines in FIG. 6, thus opening the port 65 so that air will be drawn from the exterior of the housing through the port 65 into the chamber 53 and then through the blower and outwardly at its periphery. It will be apparent that the peripheral portion of the blower and the spaces between the adjacent vanes 127 may be regarded as the outlet of the blower. A portion of the air being moved by the blower is of course di-' rected at .the inlet of the conduit 150. Such movement of the shaft 71 also moves the-valve member73 to its closed position illustrated in broken lines in FIG. 7
from the boilerchambery22through-theport60. The steam or water vaporjnow condenses to afine mist or dropletsas the temperature of thevapordrops as it mixes .with the air which isatsroomtemperature.
Thismist, i. e,,,mixture of hot water droplets and air,
' nowflowsflwitha certain: desired Velocity and ata desiredttempe'rature, asdetermined'bythespeedof-operation.of;the air mover, through the port 62 into the middle chamber 52 and, :since the port 64 is now closed, into ,the vflexible conduit. The stream :of mist flows outof the applicator atadesired velocity and temperature as determined by .the value of the resistance of the rheostat and is caused to impinge on a smallarea of the skin determined byzthe internal diameter of the applicator and the distance of the end surface 1 13 of the applicator from the skin. As a result, the,
area of the skin subjected to this stream of mist is heated and treated with the warm water droplets and is also subjected to the mechanical force of the mist which tends to dislodge extraneous matter. from the surface of the skin. The pores of the skin now tend to open, the skin being moistened and heated by the mist; The warm water droplets, alsomoistened, tend to dissolve any dirt, powder or extraneous matter adhering to the skin, thus decreasing the force with which such matter clings to the skin.
After a desired area of the skin hasbeen subjected to this stream of mist, the wheel 80 is rotated in a clockwise directiomas seen in FIG. 2, and as the recess 96 first moves out of registry with the roller 82, the mov able contact 89 of the switch 87 opens so that the electric current no longer flows through the water between the electrodes 35 and 36, thus stopping heating of the water, and subsequently the recess 91 of the cam 81 moves into registry with the roller 83. As a result, the movable contact 90 of the switch 88 moves into contact with the stationary contact 95 thus connecting the motor 102 directly across the conductors 41 and 42. The speed of operation of the motor 102 will now be maximum. Such clockwise rotation of the shaft 71 now causes the three valve members 74, 73 and 72 to move to the positions illustrated in full lines in FIGS. 6, 7 and 8, respectively, so that the ports 65 and 62 are closed while the port 64 is open. The inlet of the air mover means 120 is not in communication only with the chamber 53 and the middle chamber 52 thus creating a pressure drop within the chambers 52 and 53 and therefore, with the interior of the flexible conduit. Air now tends to flow inwardly through the applicator 112 and if the surface 113is now applied against the skin, the area of the skin enclosed by the end surface 113 will be subjected to a decreased pressure 'or suction thus tending to cause the dirt particles, oil or the like in the open pores to be moved outwardly ontothesurface of the skin and also the loosened matter on the skin to be dislodged from the surface of the skin as the applicatoredge moves thereover. There is, of course, some slight flow of airbetween the applicator edge surface. l13 and the skin so that theflow of air tends to move the particles, liquids, oils or other matter present 6 on the surface of the skin off the skin and through the conduit 110. As was explained above, the "end "surface 113 may be serrated to provide a scraping action over the skin while permitting some flow of air between the skin and the end surface at a relatively high velocity Y which would tend to mechanicallydislodgeextraneous matter present on the skin. a
It will now be seen that the illustrated=anddescribed applicator 10 employs a single air moving means for selectively varying the velocity and temperature of the hot water mist'being delivered through-the-applicator and also to provide'a decreased pressure or'suction at the applicator for'decreasingthepressure atthe surfaces of the skin and for removingextraneous matter such as liquids, oils'and dirt particles off the skin after the skin hasbeen subjected to the'hot water mist.
It will also be apparent 'that,=if desired, suitable-cosmetic, cleanser or medicating agents could be introduced into the water in the boiler chamber 22'so that the hot water mist will not be a pure water mist but would also contain such agent which would evaporate with the water and be applied to the skin at the time it is being subjected to the stream of hot water mist.
The foregoing description of the invention is explanatory only, and changes in the details of the construction illustrated may be made by those skilled in the art, within the scope of the appended claims, without departing from the spirit of the invention.
