ADJUSTABLE LAMP FOR BEDS.

Specification of Letters Patent.

Patented Sept. 21, 1915.

Application filed August 5, 1914. Serial No. 855,182.

To all whom it may concern Be it known that I, ABRAHAM GoLnKNoPF, a citizen of the United States, and resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Adjustable Lamps for Beds, of which the following is a specification.

This device, is intended as an illuminating means that may be temporarily secured to a bed or .any other-convenient place or may be removed and rested upon a table or other flat surface.

In devising my invention I have not in tended to produce a lamp of high illuminating power but rather one that will supply a small amount of illumination for a limited period of time but will supply it under the most convenient and most readily operated conditions.

The device, is adjustable throughout and the rays from the small lamp may be directed or focused to any point and the device is so constructed that it may be operated in a most eflicient manner by any one even by those not acquainted with electricity or mechanics.

The construction of my device and its method of operation will be fully set forth as the specification progresses.

The following is what I consider the best means of carrying out this invention.

The accompanying drawings form a part of this specification, in which:

Figure 1 is a frontelevation of my completed device and the fractures expose to view certain portions of the interior mechanism. Fig. 2 is an end elevation, partly in section of the structure shown in Fig. 1.

Similar reference numerals indicate like parts in all the figures where they appear.

My device consists of a battery or a single battery cell as indicated at 1, and a lamp is indicated at 2 together with certain electrical connectors and switches for operating and controlling the lamp.

At 3, I have shown a cylindrical casing of metal in which the battery is inclosed. The ends of this casing may be rounded as shown at 4 and 5 and the end 5 may be removable by means of the screw threads indicated at 6. \Vithin the opposite end I arrange and secure a disk of fiber or any other insulating material 7 and centrally disposed within this disk I have arranged a metallic contact member 8 to which one of the wires from the lamp 2, is connected.

It will be observed that only one insulated wire is used for connecting the lamp with the battery, I do this so that the device may be less complicated and I arrange that the opposite pole of the battery shall through the ordinary zinc be in contact with the metallic casing in which the battery is contained.

Extending upward from the shell 3, I have arranged a short tubular projection 9 and rotatably mounted upon the projection 9 I provide an elbowed tubular member 10, the upper end of which projects at right angles from the portion that is rotatably mounted upon the projection 9. Within the right angled portion 11 of the tubular member 10 I arrange an additional tubular member 12 and I provide that this member shall be adjustable in the portion 11 of the tube 10 and it may be telescoped in or out of that member. The outer end 'of the member 12 is downturned and is provided with a socket or screw threaded thimble 13 into which the lamp may be secured. A disk of insulating material 12 is arranged in this end of the thimble. and is secured therein and a metallic plug centrally disposed in this disk receives in contact the end or tip of the base of the lamp and secured to it is the insulated wire or conductor that passes through the tubular members 9, 10, 11 and 12. This wire that is secured in electrical contact with the lamp is joined with the wire that is secured in electrical contact with the battery and together they pass out of the case 3 and terminate in a switch 19. The length of these wires may be anything that is desired so that the switch may be placed in any convenient location.

Secured to or formed integral with the tubular member -5 and extending for the greater part of the length of one side is a semi-flexible clip H provided with a plu rality of adjusted screws 15 and 16 these screws are intended to assist the clip in retaining the device in any desired position upon the head or foot of a bed or upon the edge of any other structure. The edge passes into the clip 14.- and the screws insure that the device will not be unintentionally dislocated upon its support, the clip H may be round at the top as indicated at 17 or square. and it will be noted that the lower end of the clip extends downward to a line even with the bottom of the tubular member 3, this construction is so arranged that when my device is placed upon a fiat surface, the clip and the. lowermost point of the tubular member 3 will support the whole device in an upright position. It will also be noted that I have provided a grip or handle 18 by rolling up a portion of the lower edge of the clip 14.

I have described my device as constructed in a manner that I have found entirely satisfactory but I desire it understood that modifications may be made within the scope of the claim.

Having carefully and fully described my invention what I claim and desire to secure by Letters Patent is A device of the character described comprising a cylinder, a battery contained therein, a lamp adj ustably supported thereon, andmeans for securing the whole to a bed, said means having its lowermost end extending to the plane of the lower most side of said cylinder and cooperating therewith to support said cylinder upon a surface as and for the purpose set forth.

Signed at New York city Aug. 3, 1914.
