Application filed February 18.1918. Serial No. 217,885.

To all whom it may concern:

-Be.it known that I, Max IXIOSSDIANN, a citizen of the United States of America, residing at Brooklyn, Kings county, State of New York, have invented certain new and useful Improvements in Lamp-Stands, of which the following is a full, clear, and exact description.

This invention relates to improvements in la1np-holders or stands, one of the objects of the invention being to provide a holder or stand for electric light bulbs which consists of comparatively few parts that can be easily assembled. My improved stand or holder is arranged so that the bulb can be adjusted or moved to various positions; in other words, the bulb is swiveled to suitable standards which are carried by a base. Other features of improvement will hereinafter appear.

I will now proceed to describe my invention in detail, the novel features of which I will point out in the appended claims, reference being had to the accompanying drawing, forming part hereof, wherein Figure 1 is a side elevation of my im proved lamp-stand or holder;

Fig. 2 is a top plan view thereof, the bulb being omitted;

Fig. 3 is a top plan view of the movable support for the bulb;

Fig. 4 is an enlarged fragmentary sectional view, the section being taken on a line 1% in Fig. 2; and i Fig. 5 is a side elevation, on a reduced scale, of a modified form of my improvement.

As herein illustrated, my improved lampstand or holder consists of a cup-shaped supporting-member 6 which carries a standard 7, preferably made in one piece and shaped to form arms 8 and 9. The base portion 10 of the standard is secured to the supporting member 6, in this instance by bolts 11 and 12. Adjacent the upper end, each arm 8 and 9 is provided with an opening 13 to receive bolts or trunnions 14: carried by a clamp 15 consisting of a split ring, the clamp 15 being offset at 16 and 17 to form recesses to receive the heads 18 of the bolts 14:, which in this instance form the trunnions. The offset portions .16 and 17 receive the heads of the bolts, and consequently the said heads do not extend from the inner surface of the clamp 15 to come into contact with the socket 19 of the lamp 20. By this means, I am enabled to provide inexpensive but efiicient connections betweenthe clamp and arms 8 and 9. Nuts 21 serve to secure the bolts or trunnions to the clamp 15.

As is apparent, the outer ends of the bolts or trunnions 14, extend through the open ings in the arms 8 and 9, thumb nuts 22 serving to lock the clamp 15 in any desired adjusted position.

Instead of employing binding nuts, I'

may form a standard 23 (Fig. 5) having spring-arms 2 1 and 25 bent inwardly toward each other, as shown by dotted lines, Fig. 5. I11 this instance, the said arms would be spread apart to insert the clamp 15, the trunnions 14; being passed through openings 26. In this form of my invention, the clamp 15 would be held in adjusted positions by the pressure of the arms 24 and 25 thereon, as the arms would tend at all times to spring toward one another.

As can be seen in Fig. 1, the arms 8 and 9 of the standard 7 are passed through openings 26 and 27 in the top of the supporting-member 6, the base 10 of the standard 7 being bolted to the underside of the top of said supporting-member 6. To prevent the supporting member 6 from scratching or otherwise defacing the element to which it is applied, I provide a cushion 28, consisting of a wire 29 covered with rubber or fabric 30. The cushioning element 28 is retained by an annular channel 31 in the supporting member 6, cement or the like being employed to secure the cushioning element in said channel.

To bind the clamp to a lamp, I provide a threaded clamping screw 31 which passes freely through an car 32 and engages a threaded opening in the car 33.

What I claim as my invention is:

1. A lamp-holder comprising a cup-shaped supporting element having openings in the top thereof, a standard consisting of a base portion, and a plurality of arms integral therewith extending therefrom and passing through said openings, means to secure said base portion to said supporting element, and a clamp adjustably secured to the ends of said arms.

2. A lampholder comprising a supporting element. upstanding parallel resilient arms carried thereby, and a clamp, to engage a lamp, rotatably supported by the arms, said arms being formed to normally tend to spring toward each other whereby toward each other whereby said rotatable said clamp is held in adjusted positions by clamp is held in adjusted positions by spring spring pressure. pressure due to the tendency of the arms 3. A lamp-holder comprising a support to spring toward each other. 5 ing element, standards carried thereby, a Signed at New York city, N.
