CHRISTIAN U. WIDMER, 0F UPLAN'D, CALIFORNIA.

EL]?!C'TRIC!:LAMIE SUPPORT.

Application filed August 5, 1918.

To all whom it may concern:

Be it known that I, CHRISTIAN U. Wm- MER, a citizen of the United States, residing at Upland, in the county of San Bernardino and State of California, have invented certain new and useful Improvements in Electrio-Lamp Supports, of which the following is a specification.

This invention relates to improvements in electric lamp supports, and has for one of its objects to provide a simply constructed device whereby an electric lamp bulb may be supported in convenient position and turned to throw the light in any desired direction.

Another object of the invention is to provide a holder for an electric light bulb, with means for concentrating and increasing the intensity of the light without increasing the candle power of the lamp.

With these and other objects in-view, the

invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention V Figure 1 is a sectional side elevation of one form of the device,

Fig. 2 is a plan view of the parts shown in Fig. 1,-

Fig. 3 is a side elevation illustratingthe manner of supporting the improved device from a stationary support,

Fig. 4 is a plan view of the parts shown in Fig. 3.

The improved device comprises a funnel shaped support or shade represented as a whole at 10 open at the larger end with the smaller end extended in tubular form as shown at 11. The tubular portion 11 is designed to receive and hold the smaller portion 12 of an electric lamp socket, indicated as a whole at 13, and from which the conductor cables 14 extend, as shown.

Attached to the tubular portion 11 at one side of the shade. or support is a tubular socket 15, the axis of the latter being directed at right angles to the axial line of the conical shade. The electric bulb is indicated as a whole at 16 and when coupled to the socket 13 extends -into the interior of the conical shade 10. Detachably supported within the shade 10 in advance of the bulb 16 is an annular frame 17 supporting a lens 18 through which the light from the bulb Specification of Letters Patent.

is thrown. The lens operates to concentrate the light and accentuate its radiance. The annular lens supporting frame 17 rests against the interior inclined walls of the shade 10 and is detachably secured thereto by one or more clamping devices or clips 10' secured to the walls of the shade and engaging the rim of the frame-17 as shown. The frame 17 is preferably substantially conical in shape with its small end extending in the direction of the large end of the shade, and the small end of said frame is formed with a retaining flange 12 which fits over the lens 18 and serves to center said lens within the shade at a point in advance of the electric light bulb.

The shade 10 may likewise be supported from the head, and when thus employed a head encircling band, represented as a whole at 19, is provided and divided at the rear and the. terminals coupled-by a strapdevice 20 including a buckle 21. By this means the band may be adapted to heads of varying sizes. The band 19 may thus be attached to the head with suflicient pressure to maintain it in position.

Rising from the band 19 at opposite sides is a curved support 22 passing over the head and connected at 23 to the tubular portion 11 of the shade. When thus arranged the open end of the shade 10 extends forwardly and above the eyes of the person who wears,

the band, thus directing the rays of the light forwardly and downwardly upon the object at which the person is looking, for instance a book, paperor other readingmatter, or the work upon which the person is engaged.

The light may also be thrown inany desired direction by simply turning the head, as will be obvious.

When the shade 10 and its attachments is to be located otherwise than upon therhead, the socket 15 will be utilized to receive an adjustable bracket device which is adapted to be attached to a suitable support. The preferable form of the coupling between the socket 15 and the support is illustrated in Figs. 3 and 4 and comprises supporting

arms

24 and 25 overlapping at their confronting ends and swingingly coupled by a clamp bolt 26 and wing nut 27 A disk of felt or like material, represented at 28, is disposed between the overlapping portions of the

arms

24 and 25, to enable the parts to be firmly clamped in adjusted position. The arm 24 is preferably twisted as shown and provided with a threaded stud 29 adapted to pass through the socket 15 and be held in position by a wing nut 30. At its free end the arm 25 is offset laterally as shown at 31 and perforated to receive a clamp bolt 32 which passes through a suitable support indicated at 33 andis held in position by a wing nut 34. By employing the various bolts and wing nuts the arms'2l-25 may be adjusted to any required extent to hold the shade or support 10 and its attachments in any desired position to thus direct the light from the bulb 16 in any desired direction and to hold the lamp socket and its bulb in adjusted position. The movement of the lamp is thus practically universal, and enables the operator to direct the light in any desired direction. The improved lamp support may be advantageously employed in connection with the book holder for which an application for patent was made by me August 6, 1918, Serial No. 248,566 and likewise in connection with the screen frame which is the subject matter of an application filed September 18th, 1918, Serial No. 254,651.

The improved device may be constructed of any suitable material and of any suitable size, and operates effectually for the purposes described.

The band 19 will preferably be lined with a padding material to protect the head. 7
