Specification of Letters Patent.

Patented time i, 1915..

Application filed July 28, 1914. Serial No. 858,612.

To all'wlwm it may concern I Be it known that I, OLIVER E. STAHL, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of- Pennsylvania, have invented a new and useful Improvement in Portable Supports for'Electric Lamps, of which the following is a full, clear, and exact description, referencevbeing had to the accompanying drawings, forming part of this specification, in which- Figures 1 and 2 are elevations at right angles to each other, 'and partly broken away, showing my improv d holder, the lamp being shown in full lines in two different positions in the two figures, Figs. 3 and i: are detail views of the lamp clamp, and Fig. 5 is a partial side view showing the holder applied to a different form of lamp. 1

My invention has relation to a portable support, or holder, for electric lamps; and is designed to provide a simple, inexpensive and convenient device of this character which can be readily applied to a desk, drawing board, table, shelf, or other support, and by means of which an electric lamp may be supported and held in any desired position relative to any particular object.

My invention will be best understood by reference to the accompanying drawing in which I have shown the preferred embodiment thereof, and which will now be described, it being premised, however, that various changes can be' made in the details of construction and arrangement of the parts Without departing from the spirit and scope of the invention as defined in the ap pended claims.

In these drawings the numeral 2 designates an incandescent electric lamp having a shade or reflector 3.

at is a split spring clamping band adapted to surround the socket portion or shank of the lamp and to be secured in place thereon by any suitable means such as the screw 5. This clamp may be used either on the usual form of incandescent lamp shown at 2, or it may be used upon an electric flashlight or lamp of the well known form illustrated at 6 in Fig. 5.

Pivoted to the clamping ring 4.- at diametrically opposite points is a yoke 7 having secured to its central portion a rivet 8 carrying a ball member 9. One of the tion of the spring to be given a universal movement whereby pivots by which the yoke is secured to the clamping ring 4 may be threaded as indicated at 10 to receive a clamping nut 11, whereby the yoke 7 may be secured at any desired angular relation with respect to said ring.

12 designates a spring clamp, which may e conveniently formed from a piece of wire d which has its two members crossed to form the clamping jaws 13 which may be engaged with any desired piece of furniture or other support, such as that indicated at 14. The jaws 13 may be covered or faced With any suitable material, as indicated at 13, for preventing injury to the furniture or other object with which they are engaged. The clamp 12 has the spring loop 15 which gives the necessary spring action to the jaws 13; and secured to this loop is a head 16 formed of two spring members 16 united by a clamping screw 17 and nut 18. Formed between the end portions of the two members 16 is a spherical socket 19 which is adapted to receive the ball member 9 of the yoke 7 The edges of the two members forming this socket may be formed with a number of recesses or notches 20, any one of which can be engaged with the shank or stem of the rivet 8 for the purpose of holding the lamp in the position to which it has been adjusted.

The provision of the ball and socket connection between the yoke and the head porclamp enables the lamp it may be readily held in any desired position with respect to a given object. The number of positions in which the lamp may be supported is further increased by the provision of the pivoted yoke 7. Thus, in Figs. 1 and 2 this yoke is shown as turned to a position at substantially right angles to the plane of the ring 4; whereas in Fig. 5 it is shown as moved into a plane substantially parallel with the plane of the ring 4.

he device is simple and inexpensive in its construction; can be quickly applied to a lamp, and forms a very convenient portable support which may be used for a large variety of purposes.

I claim:

1. A device of the character described, comprising a lamp engaging clamp, and a support engaging clamp, said clamps having a ball and socket connection, and the members of said connection having interen aging means for holding the parts in di erent relative adjustments, substantially as described.

2. A device of the character described, comprising a lamp clamping band, a yoke adjustably pivoted thereto, and a support engaging clamp, the support engaging clamp and the yoke having a universally movable connection between them, substantially as described.

3. A device of the character described,

comprising a lamp clamping band, a yoke adjustably pivoted to said band, a ball member carried by the yoke, and a spring support engaging clamp having a socket adapted to receive said ball member, substantially as described.

i. A device of the character described, comprising a lamp clamping band, a yoke adjustably plvoted to said band, a ball member carried by the yoke, and a spring supset my hand.
