ELEGTRiG-LIGHT-STA'ND ADJUSTER.

Application filed January 13; 1928. Serial No. 612,492.

To all whom it mag concern: c Be it known that we, ANTHONY 'Mn'YEns and HArRY SIMMONS, citizens of the United States, residing at New York, in the county 6 and State of New York, have invented certain new and useful Improvements in Elece tric-Light-Stand Adjusters, of which the following is a-fu'll, clear, and exact specification, V 7 10 This invention relates to means for adjusting or securingielectric light stands or lamps to various .fixtures,; such. as tables, mantel shelves, window sills, or bedsteads where most convenient to the user for read- 16 ing, sewing, etc; I

One object of the invention is to pro ,vide clamping means for the purpose stated on the base of a stand lamp which may also be used in the ordinary way on a table, or

20 the like, without bringing'said clamping means into play, and to arrange said clamp ing means in the base of the lamp so that it will not interfere with the setting ofsaid stand on a level surface. At the same time, said clamping means is adapted to be projected below the base of the lamp for securing the same to the edge of a table, or to other fixtures, whenever desired.

Another object is to provide improved means for actuating said clamping means from above or outside the base of the lamp to which it is attached. Still another object is to provide a lamp of the character described with an adjustable socket member which may be turned to assume different angles with respect to the stand, and may also be rotated about the vertical axis of said base so as to bring a lamp mountedin said socket into the position best suited for its use no matter how the base is secured to a fixture by the clamping means. Other objects will appear as the description proceeds. c K v The invention will be first hereinafter described in connectionwith the accompanying drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description. 50 In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout thefseveral views c Figure 1 is a side elevation, partly in vertical section, of a lamp or stand constructed substantially in accordance with this invention and adjusted or clamped to the edge of ashelf or other fixture. Q i

'Figure 2 is a bottom plan of the stand or lamp as shdWninFigure 1 except that'the fixture is omitted and the clamping means folded into the'cavity in the base of said stand. V

Figure '3 is a broken section on the line III-III of Figure 1 with the parts drawn to a larger scale to illustrate moreclearly the connection between the clamp and its operating device, and Figure 4 is a detailed plan View ofa modified form'of operating device for the clamp which maybe used in place ofthat illustrated in the other views;

The lamp stand comprises ajbase 1- preferably of sheet metal formed with a recess 2 in its bottom, a tubular standard 3 rising from the center of said base and preferably secured rigidly thereto by solder or the like, and a. socket, member 4 arranged at the upper end of the standard 3 and hinged at 5 u per, end of the rod 6 and the lamp socket 4 is placed under sufficient tension by a bolt 7 to insure said socket remaining in any angular adjustment desired. Said socket 4t may be fitted with an electric light bulb 8 V and a shade or reflector 9, as shown in Figures 1 and 2, and a cord or wire cable 10 may lead to said socket through the tubular rod 6 and the base of the lamp.

The rod 6 and lamp socket 4: hinged thereto maybe rotated in the standard 3 so as to swing the bulb into different positions about the base, and in orderto retain said rod in its different adjustments or positions when rotated in the standard,a coiled spring 11 is mounted aroundsaid rod within the standard, one end of said spring bearing against a collar 12 fixed on the rod and the other end of said spring bearing against a washer 13 and tending to ress itinto frictional contact with the top of the base 1 within the lower end of the standard. Said spring bearing upon the collar 12 tends to raise the rod 6 and thus presses a washer 1 1 on its lower end against the upper surface of the top of the base. The washer l l is held on the lower end of the rod 6 by asuitable nut 15, or the like.

A radially projecting arm 16 is fixed to turn with the rod 6 and extends into the path of a stop 17 fixed to the base within its recess for limiting the rotation of said rod to one revolution about the base, so as to prevent undue twisting of the wire cable or cord 10. Said arm 16 may be secured between the washer 14 and nut 15 and have a portion 18 bent down against one of the flat sides of the nut to insure the turning of said arm with the rod, as shown in Figures 1 and 2. The cable or cord 10 may enter the base at any desired point, as through the eyelet 19 in the side of said base.

A clamping jaw 20 is hinged at one end on a cross pin 21 in the recess of the base and is adapted to be folded into said recess so as not to interfere with the base resting evenly upon a table or other level surface. A coiled spring 22 mounted on said pin 21 and having its ends bearing respectively against the base and clamping jaw tends to hold said clamp in folded posit-ion and also exerts suflicient pressure upon said clamp, when swung outward for engagement with a fixture, to fasten the stand or lamp to said fixture whether applied to the edge of a horizontal shelf or fixture'23, as shown in Figure 1, or applied in any other position to any other kindof fixture, such as the bars of a metal bed, for instance, as will be readily understood. The clamp or jaw 20 is made hook-shaped, as at 24, in order to better grip a fixture of angular or round contour, and said clamp is preferably made of rigid wire 25 or the like bent into the form shown and covered or encased in rubber tubing 26, so that it will not mar the fixture to which it is applied. The base of the stand is fitted with a rubber encased wire 27 for the same purpose.

The clamp 20 is operated from above the base of the lamp by means of a hand lever 28 which may be made of wire as shown in Figures 1, 2 and 3., or which may be formed in a solid casting 29 as illustrated in Figure 4-. Said wire lever 28 is bent to form oppositely extending loops 30 which rest upon the top of the base of the lamp, while the middle portion of said wire is bent to form a handle loop 31, the end portions 32 of the wire being spread apart to engage the hinged end of the'clamp 20, while the portions 33 of said wire just below theloops 30 are arranged close together where they pass through an opening 34 in the top of the lamp base which serves as a ful rum for the lever. It will thus be seen that the clamp 20 may be swung downward out of the recess in the lamp base by pressing upward on the handle loop 31, or outer end of the handle lever 28, as shown in Figure 1, and that this outward movement of the clamp placed the spring 22 under suflicient tensionto clamp the lamp firmly upon a fixture to which it may be applied.

In Figure 4, the hand lever casting 29 has oppositely extending lugs 35 corresponding to the loops 30 on the wire lever 28, and oppositely extending arms 36 corresponding to the spread ends 32 of the wire lever for engaging the hinged endof the clamp.

We claim:
