Application fileti April 2. 1953 To all whom it may concern a citizen of the United States, residing; at Vi ashington, in the District of Columbia, have invented certain new and useful Improvements in Electric Lights, of which the following is a specification, reference being bad therein. to the accompanying drawing.

This invention relates to lights, and more particularly to an electric light attachment for battery cells.

The principal object of the invention resides in the provision of an attachment of simple construction which may be easily attached to or removed from the battery cell.

Another object consists in forming the at tachment from a blank of metal. adapted to be pressed and bent to form an arm for connecting to the cell, a socket for the light bulb, and. reflector.

A. further object consists in novel means for swinging the attachment for making or breaking a contact and the provision of means for connecting the attachment to a plurality of cells if desired.

lVith these and other objects in view, my invention consists in the novel details of construction and arrangement of parts which will be more clearly understood from the following specification and drawings. in which Figure l is a side elevation of my attachment connected in position upon a. cell.

Figure 2 is a top plan.

Figure 3 is a frontelevation of my at tachment, showing only a portion of the cell.

Figure 4 is a plan of the blank from which my attachment is formed.

Figure 5 is a plan of the insulating strip for securing my attachment to the cell post.

Figure 6 is a side elevation of a slightly modified "form of attachment, with only a portion 01? the cell illustrated.

Figure 7 is a top plan of the modified form of invention.

Figure 8 is a top plan showing the mot ified form of invention used in connection with two cells.

Figure 9 is a plan of the blank from which the. morflilied term of attachment is :t'ormed.

In the drawings, the numeral 1 indicates a dry battery cell having the central carbon. post 2 and outer zinc post 3. A. binding nut st is received upon the threaded end of the Serial No. 270,714..

post 2, and a ljll'lCllng nut 5 is received upon the threaded end of the post 8.

' In the preferred form of my invention, the attachment is formed from a blank of metal illustrated in F lg. 4t of the drawings. This blankv comprises a circular body portion 6. having an opening- 7 therein. and an arm 8 having ears 9 formed on opposite edges thereof. intermediate the ends. The circular portion 6 will be pressed or stamped to form a reflector 10,which is bent to ex end at right angles with respect to the end of the arm 8. The arm adjacent the reflector, is bent to form a goose-neck portion 11.. and the outer end of the arm is slightly curved as shown at 12 for a purpose to be later described.

The ears 9 are adapted to be bent around the side edges. and under the bottom, of a strip 13 Of insulating material. This strip 13 is provided, adjacent one end, with an opening which is reinforced by means of a metal ringll. Bvconnecting the arm 8 to the insulating strip 13. by means of ears 9, it will be seen that the arm may be adjusted with respect to the insulating strip so as to bring; the arm in proper position for forming the contacts to be later described.

An electric light bulb is shown at 1.5 and the threaded end. 16 extends through the opening '7, in the reflector, so that its rounded end 17 may contact with the upper end of the post 2 or the binding nut as more particularly illustrated in Fig. l of the drawings.

The parts will be assembled as illustrated in Fig of the drawings. The post .2 will pass through the opening or ring" 14, in the insulating strip 13, and by the binding nut 4 will be held in position. The arm 8 will be adjusted on the strip 13 so that the rounded end 17. of the threaded portion 16 of the light bulb to, will contact with either the end of the post or with the binding nut. The goose-neck ll forms a spring for holdingthe rounded portion 17 in coiract with the post or nut. The strip 13 will be loosely held upon the post sothat by grasping" the curved end 12. of the arm the whole attachment may be swung either into the full line position, indicated'in Fig. 2, or into the. dotted line position shown in this figure. l hen swung into the full line position the contacts will be broken so that the light will be out. ll hen it is desired to light the bulb the arm is grasped and. the attachment swung into the dotted line position with the curved portion 12, of the arm 8, engaging the upper end of the post 3. The circuit will then be completed and the bulb lighted. By curving arm 8, as shown at 12, it is placed under tension so that it will be held in close contact with the end of the post. By again turning the attachment ino the full line position, the light will be extinguished.

In the modified form of the invention the cell is indicated at 18, the central carbon post at 19, and the outer zinc post at 20. A binding nut 21 is received on the threaded end 01 the central post 19, and a similar binding nut 22 on the threaded end ofthe post 20.

In this modified form of invention the attachment is formed from a blank illustrated in Fig. 9. This blank comprises a circular body portion 23 having an opening 24, adjacent the edge thereof, and an arm 25 having a plurality of longitudinally spaced openings 26. The circular body portion 23 will be pressed or stamped to form a re- Elector 27 which is bent to extend at right angles to the end of the arm 25. The arm 25 will be curved as indicated at 28 for a purpose to be later described. An electric light bulb as indicated at 29 and the threaded shank 30 thereof, extends through the opening 24, in the reflector 27, and the rounded end 31 is adapted to be brought into contact with the upper end of the post 19 or with the binding nut 21.

In the modified form of the invention, the parts will be assembled as more particularly illustrated in Fig. 6 of the drawings. The post 20 will pass through one of the longitudinally spaced openings 26, in the arm 25 and the bindingnut 22 will be adjusted so as to hold the arm on the post, but at the same time to allow it to be swung from one side to the other. W' hen not in use, the arm will be swung into the full line position illustrated. in Fig. 7 of the drawings so that the rounded portion 31 of the lamp bulb will not contact with the post 19 or nut 21.. When it is desired to light the bulb the attachment is swung so that the rounded portion 31, of the bulb, will contact with the end of the post 19 or the upper face of the nut When in this position the bulb will be lighted and the light reflected to the desired position by the reflector 27.

In Fig. 8 I have illustrated the modified form of my invention as attached for use with two cells 18. When used with two cells the post 20 of one of the cells will pass through the outer opening 26, in the arm 25. The binding nut 22 will hold the arm upon the post. The two central posts will be con nected by means of the wire 32 and to light the bulb the attachment will be swung so that the rounded end 31 of the bulb will terms a support for the light attachment and when in use the cell may be carried to the desired position, and set so as to reflect the light in any desired position. By having the reflector at right angles with respect to the arm, the light will be reflected to the side of the cell while the cell is supported in vertical position.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination with a battery having terminals extending therefrom, a strip of insulating material having an opening to receire one of the terminals, an arm bent intermediate its ends to form a spring, ears formed on the arm for engaging and adjustably connecting the arm to the insulating st up, a reflector formed on one end ofthe arm, and an electric light bulb carried by the reflector, the bulb adapted to engage one of the terminals and the arm the other, to complete a circuit to illuminate the bulb.

2. In combination with a battery cell having a central contact post and an outer contact post, a strip of insulating material pivotally connected to one of the contact posts, an arm adjustably connected to the insulating strip and adapted to engage the other contact post, said arms having ears adapted'to engage the edges of the insulating strip, and an electric light bulb carried by the arm and adapted to engage that post to which the insulating strip is pivoted.

3. In combination with a battery cell having a central contact post and an outer contact post, a st'ip of insulating material pivotally connected to one of the contact posts, an arm connected to said insulating strip and bent intermediate its ends to overlie both contact posts, one end of the arm adapted to contact with one of the posts, and the other end carrying an electric light bulb adapted to contact with the other post.

In testimony whereof I hereunto afiiX my signature in the presence of two witnesses.

CHARLES HERBERT BURTON.
