RICHARD M. RUNGE, OF MERIDEN, CONNECTICUT, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO THE MILLER COMPANY, OF MERIDEEI, CONNECTICUT, A CORPORATION OF CONNECTICUT.

LAM]? SUPPORT.

Application filed February 27, 1924. Serial No. 695,487.

The ob'ect of this invention is the manufacture a sliding arm for posts for use in bridge, table, floor lamps or the like. The bracket arm is held in any desired position by means of a spring member which presses against the post, the spring being provided with arms which serve to release the spring pressure so that the arm can be moved up and down.

Fig. 1 is a side elevation of the device applied to a post.

Fig. 2 is a front elevation of the same.

Fig. 3 is a plan view of a form ofv spring with arms used in the device.

In lamps of this character it is desirable not only to be able to move the bracket arm carrying the source of light in a horizontal direction, but in a vertical direction as well, so as to adjust it to various chair heights. A device for insuring such adjustability must be easily and readily manipulated from any position and from any angle.

In Fig. 1, 1 is the post of any lamp support, such as a bridge lamp, or a standing or table lamp and 9 is a bracket arm with socket members which can be of any preferred form. The arm is supported by two ring members 7, connected by a plate 8, permit-ting the insertion of a spring 3, having two wings 4 between the post and the plate, for purposes hereinafter set forth.

The rings and consequently the attached bracket arm supporting the socket members are normally held securely on the post at two points by means of the pressure of the inner surface of the arms 2 of spring 3, the outer surfaces of the arms bearing against the inner surface of plate 8. Except when they are rigidly held by the spring pressure the rings 7 and the attached bracket arm are adapted to slide easily up or down on the post 1. It is only necessary to press the wings l of the spring 3 backward to release the pressure of the arms from the post in order that the rings and consequently the bracket arm and socket may be moved up and down.

From the above it will appear that the adjustment member can be readily manipulated from any position, a simple pressure of the thumb and finger on the extended wings being sufficient to release the holding device. When the pressure on the wings is released, that is when the thumb and finger are re moved, the arms of the spring bear against the post at two points and maintain the holder and bracket arm at the desired height. In addition to these features the rings and the bracket arm can be turned in a horizontal direction at all times.

I claim:

1. An adjustable lamp support comprising a post, a member encircling the post and slidable thereon, a lamp bracket attached thereto, and a vertical spring lying between the sliding member and the post and provided with horizontal arms extending beyond the post adapted to release the spring pressure when bent backward to permit the sliding member and bracket to move freely on the post.

2. An adjustable lamp support comprising a post, a member slidable thereon, a lamp bracket attached thereto and a vertical spring acting on the sliding member, the sliding member comprising top and bottom rings encircling the post and a vertical plate connecting the rings, the spring being constructed to lie between the post and the plate and being provided with horizontal arms extending beyond the post, adapted to release the spring pressure when bent backward to permit the sliding member and bracket to move freely on the post.

Signed at Meriden, in the county of New 85 Haven and State of Connecticut, this 23rd day of February, 1924.

RICHARD M. RUNGE.
