J Application filed May 10,

To all whom it may concern:

Be it known that I, JOHN HAAOK, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Improvement in Electric Lanterns, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to lanterns as a class.

The object of my invention is to provide an electric lantern, conveniently portable by hand, with an electric cell therein arranged to be easily accessible and a particular arrangement of electrodes and switches for the cell and lamp. These objects, as well as other advantages, I attain by the construction, combination and arrangement of parts illustrated in the accompanying drawings which form a part hereof.

Figure 1 is a side elevation with parts 1n section, and lamp opened, indicated in dotted lines.

Fig. 2 is a top plan View of the body or cell container with cover removed, showing the cell.

Fig. 3 is a bottom plan view of the hinged top and cover showing contact parts.

Fig. 4; is a sectional view of the handle grip on line H in Fig. 1.

Like characters refer to like parts in the views.

The lantern has two members, the cell container being member 5, and the lamp and mechanism container, being member 6. l/Vithin the member 5 is a recess of convenient size, in which an electric cell 7 of common type is placed, preferably of the character known as a dry cell. The cell has electrodes 8 on its upper surface, connected with its respective elements. A carrying handle 9 is hinged on opposing sides to the member 5. The member 6 is hinged at the rear to the upper part of the member 5 by the hinge 10 and has a securing catch 11 in front. The member is formed with a hollow, horizontal grip or handle 12, having a reflector 13 secured upon its forward end and a socket 14 in its center adapted to receive a lamp 15. Electric terminals 1% and 14 are placed in the socket and furnish the usual type of connection between the lamp and the circuit wires. Within the cap portion of the member 6, which fits over the top of the memher 5, a disk, with circular insulations 16, is rigidly secured. The disk has inner and ELECTRIC LANTERN.

Specification of Letters Patent.

1920. Serial No. ssaaza' v outer circular terminals 17. These terminals are positioned to engage the respective cell electrodes 8, immediately beneath them, when the lantern is closed. An insulated wire 18 extends from the inner terminal 17 to an insulated conducting terminal upon and near the rear end of a bar 19, which is secured in the handle 12. A spring closer arm 20 has one end integral with the said rearbar terminal, its free end extending below a second insulated conducting terminal upon and near the forward end of the bar 19 in a positionwherefrom the free end of the arm 20 may be pressed into engage ment with the opposing terminal above. A wire 18 extends from the outer terminal 17 to thesocket terminal 14?. With'a lamp in place as shown, the circuit continues through the lamp to the opposing terminal 14", thence by a connecting wire to the forward terminal on the bar 19. The closer arm 20 is retained by tension free of the opposing terminal. A finger block 21 is slidably arranged within the handle 12 longitudinally below the arm 20; The block 21 has a finger projection 22 extending downwardly through a slot in the handle 12 and the upper, forward part of the block has an inclined surface which engages the arm 20.

It will be seen that when the lantern is closed with the cell placed in the member 5, its electrodes are at all times in engagement with the circular terminal strips 17 regardless of how the cell may be turned. It will be seen also that a direct and continuout metallic circuit is provided through the circuit closer and lamp. The common practice is to carry a circuit through a ground in the lamp but this dissipates the electric energy, requires more power and weakens or exhausts the cell much sooner. This difficulty I have overcome and find the lamp in my device can be kept lighted with the same cell for a much longer time and with a better illumination. The finger block 21, when moved forwardly, engages the arm 20, raising it upon the horizontal surface of the block and the contact point at the end engages the forward terminal on the bar 19, the block being retained in this position by the downward pressure on it of the arm 20. The circuit is thus closed and the lamp kept lighted. Upon pressing the block rearwardly the circuit is opened and the light extinguished. It will also be noted that the block may be pressed upwardly when the I Patented July 5, 1921'.
