6 Claims. (Cl. 132-36) This invention relates to apparatus for treating live or growing human hair, in which a device for treating or operating upon the hair is mounted on a stand or support by which the treating-device can be adjusted and held stationary in differentl positions enabling it to conveniently and properly operate upon tresses or locks of hair on different portions of the subjects head.

Particular objects of the invention are to provide a practical and desirable apparatus of novel construction, by which the treating device can be quickly and easily adjusted, practically universally, so as to hold it stationary in whatever different positions may be necessaryto most elliciently and conveniently treat or operate upon tresses or locks of hair on all portions of the head; to provide an apparatus having means for' treating chamber of the casing, for the purpose elevating and lowering the treating device and i also adjusting it angularly both horizontally and Vin different vertical planes at an angle to each other when at the desired elevation in order to set and hold the device in different desired positions relative to di'erent portions of the subjects head.

Further objects and advantages of the invention will appear from the following specification of the preferred embodiment of the invention, shown in the accompanying drawings, and the novel features of the invention are set forth in the appended claims.

In said drawings:

Fig. 2 is fragmentary, transverse, sectional elevation thereof, on* a larger scale, on line 22, Fig. 1.

Fig. 3 is a fragmentary front elevation of the apparatus.

Fig. 4 is a sectional plan view thereof on line 4 4, Fig. 1. I y

Fig. 5 is a longitudinal, sectional elevation thereof, on line 5 5, Fig. 3.

Fig. 6 is a sectional elevation on line 6-6, Fig.

Fig. 7 is a rear elevation, partly in section, on line 1 1, Fig. 6.

The hair treating ,device I 0, as illustrated in Athe drawings, is in the form of a casing provided with a cover or movable section II adapted to be opened for placing a tress or lock of hair therein and providing, when the cover is closed, a' treating chamber in which the hair maybe treated or processed for one or another purp'ose. For instance, as disclosed in the copending appliof straightening curly or kinky hair. In such uses of the device, the tress of hair being treated is preferably gripped close to the head and held to prevent any pull on the hair from being transmitted to the head and for this purpose protruding lips IIa may be -provided at the end of the device nearest to the head between which the tress enters the casing and which clamp the root end of the tress. When the hair is thus gripped, the device should be held immovable to prevent pulling the hair, with consequent discomfort to the subject. They treating device may be used for other desired treatments of the hair, and it may be of other constructions adapting it for performing one or another kindof treatment of the l hair.

For thus stationarily supporting the treating device or casing I0 in different desired adjusted positions, it is mounted on a stand or support which is preferably constructed as illustrated in the drawings, and comprises a base I 2, a standard or post I3 which isvertically adjustable on the base I2, a swivel head I4 which is angularly adjustable in a horizontal plane 0n the upper end of the post I3, a bracket or member I5 which is pivoted to the swivel head to swing about one horizontal axis and on which the device or casing I0 is pivoted to swing about another horizontal axis disposed at an angle to the first horizontal axis.

The post I3 has a vertical lower portion which is arranged to lslide vertically in an upright, .tubbular column or portion I6 of the base and is adjusted vertically therein, preferably by mechanism comprising a hand crank Il secured to the shaft of a worm I8-which meshes with a. worm wheel I9 on a shaft 20 to which is flxed a pinion that meshes with a toothed rack 2I on the vertical portion of the post I3. By turning the crank in one direction or the other, the standard can be raised or lowered in the base and will be held at the adjusted elevation by reason of the toothed engagement of the worm wheel with the worm. Preferably, the post I3 has a laterally and upwardly inclined upper portion with an enlarged upper end, on which the swivel head I4 is mounted by means of a vertical stud or shaft 22 xed to the swivel head and arranged to turn in a vertical bearing hole 23 in the upper end of the post I3. Fixed to the lower portion of shaft 22 is aworm wheel 24 which is located in a chamber or cavity in the post enlargement I3 and meshes with a worm 25. 'I'his worm is housed in the cavity in the post enlargement and is xed on a shaft'26 which is journalled in suitable bearings in the post enlargement and provided at one end with a hand wheel 21 for rotating the worm. The swivel head can be rotatably adjusted in either direction about the axis of shaft 22 by turning the hand wheel Ain one or the other direction, and the swivel head will be held stationary in the position to which it is adjusted by the toothed engagement of the worm wheel with the worm.

'Ihe pivot bracket I5, as shown, is formed with a horizontal bearing sleeve or portion 30 from which a lug or part 3i projects downwardly and is pivoted to the swivel head I4 by a pivot or pin 32, preferably secured in holes in lugs 33 and 34 rising from the swivel head at opposite sides of the lug 3| o! the pivot bracket. A pivot or pin 35 passes through and bears in the bracket sleeve 30 and in holes in hinge brackets 36 and 35a v which may be bolted orotherwise suitably secured to the bottom of the casing or device ID or it may be secured in the sleeve and the hinge brackets 35 and 36a permitted to turn on the ,ends of the pivot. The two pivots 32 and 35 are disposed horizontally at an angle, preferably a right angle, to each other, so that the pivot bracket can swing or tilt about the axis' of pivot 32 in one vertical plane while the device I0 can swing or tilt about the axis of the other pivot 35 in a vertical plane which is at an angle or perpendicular to the iirst mentioned vertical plane.

Suitably secured to lug 3l' of the pivot bracket by screws or otherwise, is a worm gear segment 31 which meshes with-a worm 38 secured to a shaft 39 which is journalled in suitable bearings on the swivel head I4 at opposite ends of 'the worm, and to one end of which shaft is xed a hand wheel 40 for turning the worm. The worm 33 is located within a cavity or chamber 4I in the swivel head which serves as a casing or housing for the worm gearing, and is adapted to contain a lubricant for the gearing and shaft bearings. By means of the hand wheel 40, the pivot 4 operator, by the use of only one hand.

ranges oi movement. The means for this Ivpurpose, as illustrated in the drawings, includes a stop in the form of a loop clamped on bearing arm 43 of the pivot bracket I5 and against the upper end of which the worm segment 43 is adapted to strike to limit the downward tilting movement of the iront end of the treating device. Stop pieces 5I suitably secured to the lug 33o! the swivel head at opposite sides of lug 3IV oi the pivot bracket I5, linut sidewise tilting movement of the device in either direction by engagement of the lug 3| with one or the other o! these stop pieces.

With the apparatus constructed as shown and described, the post I3 can be raised or lowered by turning the hand crank I1 to place the treating device or casing I0 at the elevation oi the subjects head, and the treating device or casing can then be swung horizontally either to the right' or left, and the front end ofl the device tilted or tipped upwardly or downwardly and also tilted sidewise to either s'ide by appropriately turning the worm operating wheels 21, 40 and 41. Thus, the device can be adjusted to whatever position may be necessary to most conveniently and eiiiciently operate upon or treat a tress of hair on any portion of the subjects head, and the device will be held stationary and in the adjusted position, whatever that may be. Any desired adjustment can be quickly and easily effected by the f 1 claim:
