To all: whom it ma concern:

Be it known t at I, AUoUs'r BoUcHERY, acitizen of the United States, residing in the borough of Brooklyn, in the county of Kings, cityand State of New York, have invented new and useful Improvements in Suction Supporting Devices, of which the following is a specification.

This invention relates to suction supporting devices particularly adapted for use in connection with the base'of a portable supmirror or other at an angle to the horizontal, such as a window pane or mirror of a dresser or the like, and it is the object of the invention to provide a suction supporting device of 'this character which is cheap and simple in construction and eflicient in operation.

Incarrying out the invention I provide a rigid hollow base by which the lamp or mirror is supported, a suction cup of suitable material, such as rubber, has a stem connected thereto whereby it is slidably supported in the base, and with which stem a spring cooperating tensioned to draw the suction cup into and maintain it within the base. A finger-piece secured to the stem of the suction cup extends through an opening in the lamp or mirror support to manipulate the suction cup to project it beyond the base against the tension of the spring to cause it to engage with the surface from which it is desired to sustain the lamp or mirror. The base when the pressure is re:

leased on said finger-piece due to the action of the spring firmly presses or bears against the surface from which the device is sustained preventing sagging of the lamp or mirror, and the pressure of the spring on the stem of the suction cup tends to increase the vacuum in the suction cup by exerting a pull thereon.

A further object of the invention is to adapt a suction device of this character to a portable electric lamp support in which a spool or reel upon which an electric current conductor is adapted to be wound is rotatably supported in a hollow base by a stem fixed to and extending outward from the axle of the spool and which stem also serves as the support for the lamp or bulb.

In the drawing accompanying and forming a part of this specification, Figure 1 is a sectional side elevation of a portable electric lamp support or stand with an embodiment of my invention applied thereto showing the lamp support sustained by the suction ,cup from a glass surface which is perpendicular to the horizontal. Fig. 2 is a sectional side elevation similar to Fig. 1, but showing the manner of applying the suction device; and Fig. 3 is a plan view of a blank from which the finger-piece for the stem of the suction cup is formed.

Similar characters of reference designate like parts throughout the different views of the drawing.

In the drawing I have illustrated an embodiment of my invention in connection with a portable electric lamp support or stand, comprising a hollow base 4 open at the bottom with'a nipple 5 projecting centrally from the top, and said nipple having an opening in the end. Seated in a recess formed in the juncture of the base and nipple is a washer 6 the opening in which is'of the same size as the opening in the end of the nipple for a purpose to be hereinafter described.

A spool or reel is inclosed by the base upon which to wind or coil a cable 7 containing the electric current conductors. This spool consists of a substantially. flat side member 8 to lie contiguous to the inner face of the top of the base, while the other side 9 is formed with a central recess 10 to constitute the core of the spool to which the spool end 8 is fixed. Fixed at one end to an opening in the spool core adjacent the side 8 is a tubular stem 11 to extend longitudinally from the axis of the spool, said stem passing through the openings in the washer 6 a long bearing for such verse to the axis of the spool by a tubular.

couplingl4 secured thereto, said coupling having a pair of

opposite fingers

15, 15 to embrace the outside of the yielding stemfingers and pivotally connected thereto by a screw 16 passing through openings in the coupling and stem fingers with a knurled nut 17 connected to the projecting threaded end. Said screw also passes through a tu horizontal, such as a pane of of the support and confined between the nipple 5 and the ends o the coupling fingers 15. As already statedthe essential'feature of the invention is tosustain a portable su ort or stand for a lamp, mirror or the li e y means of a suction device from a smooth, non-porous surface 20 at an angle to the mirror of a dresser or the like. his suction I device consists of a cup 21 of suitable ma,-

terial, such as rubber, connected to one end of a stem 22 which may be molded directly in the material of the cup. This stem 22 1s slidably supported in the base, in'the pres-.

ent instance mounted in a support 23 in the form of a yoke fixed in the core of the spool and extends into the spool stem 11. A finger-piece 24 has a screw threaded connection with the end of the stem of the suction cup, the free end of which fin er-piece finger piece 24, as shown in Fig. 2 in full I extends through an opening in t e spool stem formed by the cut-out ortion between the spool-stem fingers, as 0 early shown in Figs. 1-and 2. This stem is stamped from sheet metal into the form of the blank shown in Fig. 3, when the up er end is bent laterally and the lower on formed into a tube and internally screw threaded. The suction cup is normally drawn into and maintained in the spqpl core within the outer contour of the base 4, as shown in dotted lines in Fig. 2, by the tension of a spring 25 coiled about the stem 22 and cpnfined between the support 23 and the finger-piece 24. One end of the cable.7 containing the current conductorsjs passed through an opening 26 in the core of the spool and then passes up through the spool stein and hollow coupling 14 to contact terminals in the lamp socket 12.

The other end pf the cable passes through an opening in the base and has a plug 27 con nected thereto.

The suction cup normally occupies the osition shown in dotted linesfin Fi 2 due to the tension of the spring 25. ould it be desired to supportthestand by means of the suction device the suction cup is projected out from. the spool core and beyond the contour of the baseby pressing on the lines, and the suction 'cup firmly pressed against the surface from which it is desired used in connection with a lam gll ass, or the to sustain the device, as shown in Fig. 1. The finger piece is then released when the spring 25 will tend to draw the cup inward creating a vacuum in the suction cup and causing it to adhere to the surface with which it is in contact. The tension of the springwill also cause the base to firmly bear or press against the surface from which it is sustained, preventing sagging of the support or stand. I 7

It is to beunderstood that the invention is not limited to the particular adaptation illustrated in the drawing; that is, who support or stand in which a reel or spool is utilized on which to wind the current conductors, since it could be used in various other forms of portable supporting devices.

Having thus described my invention, I claim: e

The combination with a base having a stem centrally thereof to support a lamp or .the like, of a suction cup; a stem to which the suction cup'is connected slidably supported in the. base and extending into the base stem and a portion extending through an opening in said stem; and a spring tensioned to draw said cup within the base; said suction cup adapted to be projected out from the base against the tension of the spring, substantially as and forthe purpose specified.
