Abstract

A bracket with a pair of parallel vertical plates engages opposite sides of a round post and has end portions projecting away from the post in opposite directions. An adjusting screw at each side of the post draws the ends of the plates toward each other to press the plates tightly against the post. A cross arm is supported by the brackets transversily of the post and carries a light socket on one end. This arm is adjustable lengthwise across the post to vary the distance between the light socket and the post.

OBJECTIVE The objective is to provide a floor light with new features such as a portable head componet which can be mounted any place on stand and steel pipe.

The base used is an auto or truck wheel which cuts costs for buyers and also saves shipping of this part.

I The electrical parts are all standard. When replacement is needed, they can be purchased at any local electrical store. i

The friction grips are positive vibration proof holding a flat surface against a flat surface with a resilient action, that does not mar steel in any locking position.

The light has easily taken off shade for use in a confined area, such as under hood of an automobile.

There is no wear out of the steel structure of this light, if damage should occur the steel structure can be straighened at any local shop, eliminating time and cost to return to the manufacture for repairs.

BRIEF DESCRIPTION FIG. 1 shows a side view of the light as a floor design. FIG. 2 is an enlarged frAgmentary plan view of the cross arm resting on its supporting plate.

DETAILED DESCRIPTION The side view of my lamp shown in FIG. 1 a base member 1 is shown, which is a used auto wheel when the lamp needs a portable base. A round post 2 extends upwardly from the base member. A sloping top plate 3 is provided with an opening through which the post extends. Directly beneath this plate there is a pair of brackets 4 on opposite sides of the post. Each of these brackets is formed from a vertical plate engaging the post along a vertical line and having an out-turned flange along its upper edge welded to the bottom of top plate 3. The resilient end portions of the vertical plates project from opposite sides of the post and are provided with holes, through which adjusting thumb screws 5 extend. The screws are threaded into nuts 6 welded to these plates. When the thumb screws are turned in the right direction, they will draw the end portions of the two vertical plates of brackets 4 toward each other to clamp the. plates against the post, whereby top plate 3 can be held at any elevation on the 0st. p Top plate 3 supports a cross arm formed from a pair of laterally spaced parallel side bars 10 welded to a rear plate 12 at one end and to a front angle plate 14 at the opposite end. As shown in FIG. 2, the cross arm straddles the post and is located between two parallel guide bars 7 welded to thetop of plate 3, on which the cross arm rests. The arm can be moved lengthwise between these guide bars. To hold the cross arm in place, a thumb screw 8 is rotatably mounted in a clip 9 and threaded in top plate 3. The ends of the clip overlie side bars 10 and press them down against the underlying plate when the screw is screwed down against the clip.

A flat bar 18 is bent to provide it with an upright portion that engages the downwardly extending portion of n le late 14, and with a fo w rdl d'r t dt 30% all: supports a base socket l9 for lig ht lg l covered by a shade 20 made of light gauge steel sheet. The adjoining vertical portions of angle plate 14 and has 18 are fastened together by an adjusting screw 16 extending through them and a coil spring 17. The screw is threaded in a nut 15 secured to bar 18. The lighting unit, consisting of bar 18, light socket l9, bulb 21 and shade 20 can be rotated around screw 16 so that the light can be directed laterally or upwardly. The light socket is connected by wires (not shown) that extend through clips 11 attached to the cross arm and back to a switch 13 carried by rear plate 12.

lclaim:

1. An adjustable rotary floor and table lamp comPrising a base member, a round post extending upwardly from said member, a top plate provided with an opening slidably receiving the post, a pair of parallel brackets secured to the bottom of said plate on opposite sides of the post and including substantially parallel plates extending vertically along the post in engagement therewith, the vertical plates having resilient end portions projecting laterally away from the post in opposite directions, an adjusting screw extending through said end portions at each side of the post for drawing the end portions toward each other to press the vertical plates tightly against the post, whereby to hold said top plate at any desired elevation on the post, a cross arm supported by said top plate transversely of the post, said arm being provided with a slot extending lengthwise thereof through which the post extends, spaced parallel guide members rigidly mounted on top of said top plate with said arm slidably disposed between them, means including a clip seated on the arm at opposite sides of its slot, an adjusting screw in the central portion of the clip threaded in said top plate and pressing the clip down against the arm to press the arm down against the top plate, and a light socket supported by one end of the arm.

2. An adjustable lamp according to claim 1, in which said top plate is inclined to the horizontal.
