STAND AND MOUNTING Filed Dec. 26,1925

max-ML Patented Nov. 25, 1930 UNITED STATES WILLIAM MEYER, or oHIcAeo, ILLINOIS STAND I AND MOUNTING Application filed December This invention relates to a stand and mounting and although not to be limited to a particular use or purpose or with a particular device, the present invention has especial utility with hair dryers of the type disclosed in my prior Patent No. 1,541,988, granted June16, 1925.

The objects of my invention are the provision of a generally improved andsimplified standand mounting affording expeditious adjustment of the height or vertical po- 1 sition of the dryer or other device and a balanced pivotal or angular mounting in which the device will be held, without clamping, in

any angular position into which it is moved.

A relatively great range of-vertical adjustment ispermitted and this adjustment is made easy or expedited by a novel balancing I spring arrangement which holds the weight of the device during the adjustment. The

pivotal mounting permits angular adjustment to any desired position and the device is self-holding in any angular position into which it is moved. The construction is simple and compact. It can be economically produced and an advantageous disposition of the parts is provided. 1 i

In order to acquaint those skilled in the art with the manner of constructing and operating a device embodying my invention, I

shall now describe, in connection wit-h the accompanying drawings, aparticular embodiment of the invention.

I In the drawings:

' Fig. 3 is a side elevational View of the dryer 1 40. showing its mounting at the upper end of the stand;

Fig. 4 is a front elevational view of the dryer showing the lamp and reflector disposition therein, and

Fig. 5 is a fragmentary detail section taken on the line 55 of Figure 4.

Referring to the drawings, the particular device. selected for illustration comprises an upright stand 5, supported at its lower end by a suitable base 6, and provided at its up- 26, 1925. Serial No. 77,888.

per end with a forked mounting member 7, for the device 8, which may be a hair dryer as already set out or a facial or scalp treatment device, or any combinaton of these or other device with which the present inventionis found desirable.

As already pointed out, the present invention has particular utility with the hair dryer of my prior patent. I also adapt that device for facial and scalp treatments, so that where I refer herein to a treatment device, I intend to include hair dryers, facial and scalp treatment devices singlyand any combination or other analogous devices.

The base 6 may be in the form of a tripod as shown, having radial legs 9 which may be providedwith suitable caster rollers 10 for supporting the device upon the flooror other supporting surface and expediting movement thereof. Substantially centrally, the base 6 has a hub or boss 11 provided with a socket 12 for receiving thelower end of the stand 5. The lower end of the boss 11 may have an opening 13 leading out from the socket 12 and internallythe socket may be provided with vertically spaced bearing surfaces 14 and 15 for holding the lower end of the stand 5 firmly in position.

The stand 5 comprises a pair of telescoping tubes or

tubular posts

18 and 20, the lower one 20 of which has a relatively fixed position, while the upper post 18 is adapted to be extended vertically from the upper end of the post 20 and to be retracted into the post 20 to vary the height of the stand. The lower end of the post 20 fits into the socket 12 and may be secured firmly therein and against accidental displacement by a set screw 25, which may be loosened to permit removal of the post 20 from the base 6.

The lower end of the lower tubular post 20 may be closed by a lug 26. The lower end of the tube 18 may eturned in or partially closed at 27, preferably with an opening 28 therethrough for placing the tube 20 in com- 95 munication with the interior of the tube 18 and preventing any pressure accumulations or dash .pot action in the tube 20 from, in

any way, interferingwith the vertical adjustment of the tube 18. A coiled spring 30 l confined in the lower tubular post 20 and between the lower end 27 of the post 18 and the plug 26 yieldably supports the upper tube 18 and balances the weight of the post 18 and the weight of the parts carried thereby, when the thumb screw 33 is unloosened.

For locking the

tubes

18 and 26 rigidly together and thereby the upper tube 18 against upward or downward movement in the tubular post 20, the upper end of the post 20 maybe provided with longitudinal slits 32' with means 32 provided for contracting this slit end upon the tube 18 without marring the same. This means 32 may comprise a ring 33 surrounding the slit end of the tube 20 and a thumb screw 33 threaded ra-' dially through the ring 33 and cooperable with the slit end of the tube 20 to contract this split end and firmly bind the tube 18 in any desired vertical position and against upward or downward movement. The spring 30 constitutes a balancing spring in that it holds the weight of the dryer or other device 8 and expedites the up and down or vertical adjustment thereof. To lower the device 8, the thumb screw 33 is unloosened and the tube 18 is telescoped or retracted into the post 20, the thumb screw 33 being again tightened to lock the device in the vertical position into which it is moved. To raise the device 8, the thumb screw is similarly unloosened, the post 18 and device carried thereby moved upwardly and the thumb screw again tightened. A relatively great range of vertical adjustment is permitted and the vertical adjustment is cushioned from one position to another.

With reference to the device 8, suflice it to say that the particular device shown comprises a casing 35 having an outlet end 36 from which the air, heat or radiant energy or any combination of these may be projected. At the opposite end, the device has a head member 38 forming an inlet which may be screened at39 and the electric motor 40 is mounted at the inlet end 38 preferably concentric with the axis of the drum or casing 35, which is shown as of cylindrical or circular formation and tapering toward its out- Suitably mounted beneath the motor 40 is a plurality of switches 42 'which may be mounted or nested side by side as shown and adapted for controlling the lamp, heater and fan or other internal circuits of the device. The conductors 45 for connecting the device into the desired electrical circuit lead into the desired circuits of. the device through the switches42 and these conductors may be provided with a standard Edison plug or other suitable connector 46. j

The forked mounting member 7 has a depending sleeved portion 50 which telescopes over the upper end of the tubular post 18 and mounts the device 8thereon. thumb screw may be provided for securing this sleeved portion 50 firmly upon the post 18, but this is not necessary and is not shown. The forked member 7 also has a pair of upright arms 52, the parallel up er ends of which straddle and are pivote at 53 to ears 54 carried by the casing 35. The ears 5& extend laterally from the rear or inlet end of the casing 35 in a common plane which, in the particular embodiment shown, is disposed below the axis of the casing 35. The outer ends of the ears 54 may be turned forwardly to dispose the common axis of the pivots 53 forwardly of the rear end and be low the axis and thereby at the center of gravity or center of mass of the device 8.

The device 8 and swingable parts carried thereby are balanced about the axis of the pivots 53. The pivoting of the device on its center of gravity disposes the mass of the device in equilibrium in all angular positions about the pivots 53, so that it will remain in any angular position into which it is moved without the necessity of clamping and without additional counterbalancing means.

The mounting of the switch below the motor 40 provides an exceedingly effective and compact arrangement and minimizes the lengths of the internal circuit or circuits of the device. This disposition, however, lowers the center'of gravity or mass of the device 8 and the pivoting at 53 below the axis of the casing 35 allows for the lowered center of gravity and disposes the axis of the pivots 53 at the center of gravity of the entire swinging system of the device.

Internally, the device '8 may be provided with a reflector 60 and the lamp 62 is mounted in the focus of the reflector, as shown. This mounting may comprise a standard Edison or other suitable socket 63 mounted upon the upper end of the relatively short sleeve or tu e 65. The sleeve 65 extends through an opening 66 in the reflector 60 and at its lower end through a diametrical opening in a post 68, which post 68 is rotatably mounted in an arm 70 fastened by a screw 76 to a bracket which is, in turn, suitably secured to the casing 35. A set screw 72 performs the dual purpose of securing the sleeve 65 against vertical movement in the post 68 and by simultaneously clamping the sleeve 65 against the arm 7 O secures the post 68 against turning in the arm 70. The screw 76 fastens the arm 70 to the bracket 75 and permits pivoting of the arm relative the bracket, the opening in the arm 70 through which the screw 76 extends, being elongated, as shown at 78.

In use, the filament of the lamp is preferably disposed crosswise of the casmg, as shown. Should it be desired to regulate the heat derived from the lamp 62, it can be done by loosening thescrew 76 and the thumb screw 72. The lamp is then moved backward llU or forward until the desired heat is obtained and vertically as desired to position it in the focus of the reflector and when the desired adjustment is secured, both screws are tightened and theposition.

For swinging the dryer 8 about its pivots 53, a handle 85 may be fastened to the casing 35. The height of the device may be adjusted or changed by grasping the supporting fork 7 and moving it up or down as desired.

I do not intend to be limited to the precise details shown or described.

I claim i In combination, a socketed base, an upright stand comprising a pair of telesco ing members, one extending from the ot er to increase the height of the stand beyond the length of either member, member being mounted in the socketed base, a device mounted on the other telescoping member, a coiled spring confined in the telescoping member mounted. in the base and acting in compression on the device carrying member, said-members having a great vertical adjustment relative their diameters and being tubular and with their interiors in communication to permit a tight fit between said members without interfering with the relative movement therebetween, the lower telescoping member having its upper end slit longitudinally, and means comprising a ring member surrounding the slit end of said lower telescoping member and a thumb screw carried by said ring and cooperable with said slit end for locking the device supporting member against movement relative to the member mounted in the base, said spring acting only upon releaie of said locking means to hold the weight if the device and facilitate vertical adjustment of said carrying member.

In witness whereof, I hereunto subscribe I my name this 17th day of December, 1925.

WILLIAM MEYER."
