Application August 12, 1942, Serial No. 454,493 6 Claims. 1 (Cl. 136-473) 2 This invention relates to a battery box and removed, the section being taken substantially more particularly to a container for dry cells of along line 'l—'l of Fig. 6. A flexible blank ‘I (Fig. l) which is preferably formed of cardboard covered with a waterproof ing paint, is used to form the walls of the box or container. As shown, this blank has a bottom la from which extend side walls 8 and 9 and a the type usually employed in ?ash lights. One of the objects of the present invention is to provide a novel battery box for dry cells which is so constructed and arranged that different voltages may be obtained from the battery by changing the positions of the cells in the box. cover l E! provided with a trapezoidal tongue or tab Another object is to provide a dry cell con 50a.

The longitudinal partition is formed to like parts throughout the several views. It is 30 from a blank 29 (Fig. 2) which is substantially rectangular but which is preferably provided with to be expressly understood, however, that the drawing is for the purpose of illustration only small tabs Zlla, 2th and 2%0 at one end thereof. and is not designed with a View to de?ning the Blank 20 has cut therefrom one or more slots 2i, limits of the invention, reference being primarily the number of slots formed depending on the had for this purpose to the appended claims.

For example, if six the drawing, Fig. 1 is a plan view of a blank of flexible ma compartments are desired two slots are used, the slots being parallel and centrally disposed terial, such as cardboard, which is preferably with regard to a central folding line 22.

If six compartments are away of the battery box of Fig. 6 with the cells desired in the completed container then two such 2,405,034 0 4 partition blanks are used. As shown, the blank is rectangular and is provided with two slots 25, each of which extends inwardly from the .edges slits I 5 and I6 and extend downwardly along the outer face of the end wall of the container to form contacts for connecting the battery to a of the narrow sides of the blank so that when the blank is folded along line 21 the slots overlie each other to form a single slot. A suitable ad hesive is employed on the inner faces of the blank so that when the same is folded it forms a fairly rigid, two-ply partition. Tabs 25a and 251) are provided on the opposite edges of the blank be 10 “use” circuit 33, such as a flashlight bulb circuit. or a circuit such as is shown in myUnited States tween the adjacent slot and the corner of the blank, whereby the partition may be adhesively secured in position in the container, if desired. The blank is also provided with slits 23 and 23, and a V-shaped notch 250. The latter is pro vided to facilitate the insertion of tab Ida between the inner face of side wall 8 and the adjacent edges of partitions if! when the container cover I0 is closed. Novel means are provided for operatively con- - necting each cell to the next adjacent cell in series, said means being so formed as to insure a Patent No. 2,228,009, dated January '7, 1941. In order that these two contacts may be more closely situated, the end portions may be bent at an angle as ShOWn in Fig. l. Preferably all of the conducting strips are passed through their respec tive slits before the blanks are folded and the folded partition blanks are positioned so that the bottom of slots 28 in blanks 25 engage the bottom of slots 2| in the blank 20. In certain instances it is highly desirable to vary the voltage of the battery. This can be readily done by inserting one or more of the cells 34 upside down within the container. If each cell, assuming a battery of six cells, is inserted into the box with the center electrode down and in contact with portions 24b of the contact strips then a voltage of 9 volts is obtained, for example. good contact with the positive electrode of the With ?ve cells down and one up, 71/2 volts are cell and with the side wall of the case of the cell, obtained. With four cells down and two up, which case acts as the negative electrode.

These strips or conductors are tive compartments to complete the circuit when the cells are removed (Fig. 7). As shown in similar to member 24, referred to above, and as shown more clearly in Fig. 4l, comprise a central Fig. 6, the right hand cells are so positioned straight portion 24a and end portions 24b, 240. in their compartments that their positive elec The portion 24?) passes under the edge of the trodes are adjacent cover [0, and serve no func blank opposite to the half of the blank having tion except that their casings complete the circuit from one strip to the next conducting strip and the slit cut therein, and said portion, in the form shown, is bent relative to portion 24a through an therefore the lower cell of these two could be angle greater than 98° so that the free end thereof removed without affecting the nature of the cir is normally located a substantial distance above 40 cuit since portions 3H) and 240 will immediately the bottom wall of the compartment and approxi move into yielding contact to complete the cir mately at the center thereof relative to the side cuit.

When a dry cell in an inverted position is placed in a compartment, portion 2% tab lfla is folded along line 36, the last-named yields and is held in engagement with the bottom tab being tucked into the side of the box to com of the box, and also in engagement with the pletely enclose and house the dry cells. center or positive electrode 3% of the cell (Fig. 6).
