PORTABLE ELECTRIC-LAMP STAND.

Patented Mar. M5, 1915.

Application filed. August 22, 1914. Serial No. 858,009

T all whom it may concern:

Be. it known that I, AUGUST Borrower, a citizen. of the. United States, residing 1n the borough of Brooklyn, in the county of '15 structure to take up a minimum amount of space, the supporting base and the shade being adapted to be releasably connected to form a receptacle in which to inclose the lamp socket, a connecting plug and a length 2 of electric current conductor to the ends of i which the lamp socket and plug are connected when the lamp stand is not in. use and is to be stowed away.

Further objects of the invention relate to 2 a spring clamping member normally concealed by the base but adapted to be pulled out from the base to coiiperate with the latter to clamp and support the stand from a suitable support, such as a bed-stead, a dresser, a chair, desk or other object, and to slidably mount a lamp supporting stem. in the base and connect it to the clamping member, said stem having a suction supporting device connected thereto to support the'stand from a flat surface at an angle to the horizontal, said clamping member cooperating with the suction supporting device and the base whereby the latter will serve as a backing to steady the lamp stand 40 and increase the holding "qualities of the suction device when the stand is supported by the latter.

A further object of the invention relates to means to releasably connect the lamp socket to the lamp supporting stem? so that the lamp or bulb will extend coaxial with the stem or at an angle thereto.

Another object of the invention is to provide a lamp stand of this character in which the means to connect the'lamp socket to the lam base is adapted to engage in a'wooden or ike supporting surface, such as the frame of a window or door.

Q In the drawings accompanyingFand form- 5 ing a part of the specification, igure 1 is a side elevation of my improved portable electric lamp, the supporting base being. partly broken away to illustrate the clampmg member and suction supporting device. Fig. 2 is a side elevation of my improved lamp showing the same. supported by its clamping arrangement. Fig. 3 is a side elevation of the lamp with the base partly broken away and showing the lamp supported by the suction means from a surface at an angle to the horizontal. Fig. 4 is a side elevation showing the lamp socket supported by the means to connect it to the base. Fig. 5 is a side elevation showing the lamp socket supported by the base to extend lat erally therefrom; and Fig. 6 is a sectional side elevation showing the base and shade connected with the socket, plug, current conductor, and the lamp stand and shade supporting means inclosed and concealed by the base and the shade.

Similar characters of reference designate like parts throughout the different views of the drawings. As stated the object of my inventionis to provide a portable electric lamp consisting of two parts, the shade and the base arranged to be releasably connected to provide' a receptacle in which are inclosed the lamp stand supporting and shade supporting means, and to also inclose a lamp socket,

plug and a length of current conductor, and in the embodiment of my invention illustrated in the drawings I have shown the same as consisting of a base B substantially of bell-shape with the bottom flaring out, and a shade S substantially of dome-shape having means, such as a pair of resilient or yielding loops 7, to support the shade from a globe or bulb at opposite sides to have adjustment about the longitudinal axis of the lamp and also to any angle on an axis transverse to the bulb. The shade is constructed of a suitable resilient or yielding material and the periphery of the bottom is 100 of slightly greater diameter than the bottom of the base to 'pe'rmitit to engage over the bottom of the ass, and the bottom 'ofl' the 'shade is so constructed that ortions thereof Will yieldingly engage wit the base. As the shade and base are being connected the material of the shade will give or spring. and when connected releasa ly hold thenti together. i

A stem 8 is slidably mounted in the top of the base and a transverse member 11 providing a. long bearing for the stem and preventingcanting thereof, and to whichstem a lamp socket 9 is adapted to be removably connected. To support the lamp stand from a support, such as a bedstead, dresser, chair or the like, I provide a clamping member to coiiperate with the base as a clamp. This member consists of a coiled spring I) inclosed and concealed by the base and preferably wound to conform to the "base. The inner coil or whirl of the spring is connected to the stem- 8 within the base and the outer coil or'whirl engages in ahead at the bottom of the base, as shown at 12, Figs. 1 and 6. The spring at a point'between the ends is fixed-tothe base as by soldering, as shown at 13, Figs. 1' and 6. By this construction a whirl or whirls of the spring adjacent the lower end may be pulled out from the base to engage a support and cooperate with the base as a clamp to firmly secure the lamp to such support as shown in Fig. 2. Thecoils of the spring adjacent the member end and secured to the stem 8 tend to maintain the stem-in its uppermost position but permit said stem to be pushedinto the base for a purpose to be'hereinafter described.

The stemfl8 at its end within the base and within the spring has a suction supporting device, such asa suction cup of rubber 14:, to support the lamp from a surface which is at an angle to the horizontal, as shown in Fig. 3.- To cause the suction cup to engagewith the supporting surface the stem 8 is pushed inward against the tension of the upper coils of the spring forcibly pressing the suction cup against the surface. As, the pressure is released on the stem the spring will exert an outward pressure on the stem and constantly exert a pull on the suction cup. This pull on the cup facilitates the holding of the lamp by the cup as it constantly tends to create a vacuum in the cup. Furthermore, the tension of the springpresses the bottom of the base firmly against the supporting surface, whereby the base serves as a backing to prevent sagging and wabbling of the lamp. An Y essential feature is the construction of the suction cup itself and as shown consists in making the inner top surface relatively flat and to extend substantially the full diameter of the interior of the cup, as shown at 15,

with the inner surface merging into the outer surfaceby a portion 16 inclining inward and downward from the outer to the inner surface, whereby the contacting surface is comparatively thin and very elastic relative to.v the side walls of the cup and will readily conform and adhere to the surface with which it comes in contact.

stated the lamp socket is removably connected to the stem 8, and is adapted to be connected thereto to extend coaxial with the stem or laterally therefrom. For this purpose the socket has a pin 17 to engage in openings 18 extending axially into the end of the stem, or at an angle or transverselystem in this manner a tubular portion 19 on the socket embraces the end of the stem.

In Fig; 5 the pin 17 engages in a transverse opening in the stem and thelam'p and socket are supported by the stand to extend laterally therefrom. ]By the provision of the pin 17 the lamp may be supported from awooden window casing, door or the likeby forcing the pin thereinto, as clearly shown in Fig. 4c. The socket is connected to one end of current conductors 20, the other'end.

of which is connected to a plug 21 to connect the lamp to the source of current at some distance away from the place where the lamp is to be used. The condiuctomsocket andplug are adapted to be placed into the shade and be inclosed thereby when it isconnected to the. base, as shownin Fig. 6. H From the foregoing description it will be obvious that T haveproduced a portable, electric lamp which canbe disassembled andi packed into a compact structureto take up a minimum amount of space, for instance as shown by the dotted lines 22 in ig. 6, in a traveling bag or case. The specificfeatures of supporting or sustaining the lamp from a suitable support by means of the clamping member and the suction device has been divided out from the present application and constitutes the subject-matter of my copendin application, filed Janna 11, 1915, Serial 0. 1558.
