To all whom t may concern.'
Be it known that I, 'WILLIAM BALDERsToN, a citizen of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have invented a new and useful Improvement in Batteries, of which the Ifollowing is a specification.
This invention relates particularly to a plural cell dry battery; and the primary obgect is to provide a cell-holder and adapt the same to use in a suitable container, such as a lantern-casing, the construction and arrangement being such that the cells may be readily introduced into the cell-holder and automatically established in circuit when so introduced, and, further, such that when the cell-holder, loaded with cells, is introduced into'the container, the circuit is automatically established between the cellholder and the container.
in the' preferred construction, the cell- -holder is provided 'with a central dividing wall; and the cells may be inserted or removed at opposite sides of the cell-holder by lateral movement of the cells.
The preerred construction is illustrated in the. accompanying drawings, in which- Fig. 1 represents a broken vertical sectional view of a lantern provided with a casing containing the improved cell-holder; Fig. 2, a horizontal section taken as indicated at line 2 of Fig. l; Fig. 3, a view similar to Fi 2 but showing the cell-holder removed, diie cell-holder being indicated by dotted lines, however; Fig. 4, a perspective view ci the improved cell-holder; Fig. 5, a perspective view showing the contacts and connections of 'the construction shown in Fig. a; and Fig. 6, a 'view similar to Fig. 5, but showing a modiied arrangement or contacts and connections.
ln the illustration given, A represents the casing or container of an electric lantern which is supported on a spider A and which is provided with a bottom A2 and a top clo sure A3; B, the improved cell-holder; and C, C, dry cells mounted in the holder B..
The casing A is provided in its lower portion with an insulation disk l spaced above the bottom A2. The disk l is itted on its upper side with a central metal disk or contact 2 with which is connected a conductor 3 which' leads to the central contact of the its upper side with a metal ring 5 which is connected, by a conductor 6, with a contact 7 mounted on the vertical wall of the container A. Another conductor 8, which may begrounded at the base or spider A", forms the other outlet for the lamp 4. The conductor 8 is connected with a switch 9, the slide-button 98 of which may be moved into contact with the contact point 7 to complete the outside lamp-circuit.
The cell-holder B preferably comprises a pair of vertical insulation side lates l0 between' which extends a vertica central insulation wall 11, which is preferably made up of a plurality of spaced insulation sheets. as appears from Fig. 2. At the lower end or the cell-holder is a bottom wall or base 12 of insulating material which is. rigidly connected with the side walls 10 by means of lsheet-metal an le-plates 13. At the upper end of the cellolder is a top wall or insulation plate 14 'which is rigidly connected with the slde walls 10 by angle-plates l5. Storage space for an extra lamp-bulb is afforded by cutting a perforation 14 in the top-plate and recessing the upper end of the partition 11, as indicated at l1".
The cell-holder shown is adapted to receive 'four dry cells, two on each side o' the division wall 11. ln the arrangement of contacts and connections shown in Fig. 4 and Fig. 5, which are arranged to connect the, cells in series, the bottom wall l2 is equipped at its lower side with a spring contact 16 and at its upper side with a spring contact 17, these contacts being connected by rivets 18. Above the contact i7 and secured to the up er wall 14 is a spring contact 19. From this contact lea-ds a conductor 20 which is 'connected at its lower end with a spring contact 2l which is secured to the bottom wall l2 immediately opposite the contact i7 and back of the division wall 1l. Secured to the top wall lli back of the division wall 11 and opposite the contact 19 is a spring contact 22, from which leads a conductor 23 which extends to a bottom spring contact 24 which is secured to the bottom wall l2 back of the division wall ll. Directly above the contact 24 is a top spring contact 25 which is secured to the top wall llt and which is disposed back of the division wall 1l., From the contact 25 extends a conductor 26 whose lower end is connected with a bottom spring contact 27 which is mounted on the bottom wall 'l2 in iront ci' the divilll) lll
33. The contact 32 is connected with a sion wall 11 and in line with the contact 24. In front of the division wall 11 and in line with the contact 25 is a top spring contact 28, fromV which leads a conductor 29 which connects at its lower end With a spring contact 30. The spring contact 30 is located at the center of the bottom Wall 12 so as to project beneath the bottom wall, being adapted to make contact with the central contact 2 of the lantern-casing. The spring contact 16 is adapted to make contact with the annular contact or ring 5 of the lantern-casing. The conductor 20 may comprise a brass bar or strip, and the contacts 19 and 21 may either be formed integrally there-with or soldered or otherwise secured to the end portions of the strip 20. Similarly, the conductors 23, 26 and 29 may be brass strips with the Vend portions of which the corresponding contact members are suitably connected.
In each case, with the exception of thev contacts 16. and 30 of the cell-holder, the contact members are adapted to make contact with the base ortions of the zinc containers of the cel s and with the carbon poles 31 with which the cells are provided. The contacts are suitably formed to enable the cells to be shoved into the cell-holder by lateral movement; and, when this is done, the contacts between the cells and the contacts members of the cell-holder are automatically established, so that the cells are automatically connected in4v circuit. Moreover, the spring contacts are of suitable orm and strength to exert a sulicient pressure on the cells to hold them in position in the cell-holder While the cell-holder is being introduced into or withdrawn from the lantern-casing..
The construction described is simple, durable, ermits easy insertion and removal of the ce ls, and insures against improperly connecting the cells. When the cell-holder is introduced into the lam casing, the circuit is automatically establlshed between the cell-holder and the external circuit of the 1 lamp.
In themodication shown in Fig. 6, the' contacts and connections are so arranged as to establish the cells in multiple serles. In this case, the contacts for the external portion of the circuit are designated 32 and of bottom cell-contacts 34 and 35, w ich correspond in position with the contacts 17 and 21. Assuming cells to be in position abovethe contacts 34 andk 35, the current passes thru both cells to a pair of upper cell-contacts 36 and 37. From these contacts, a conductor 38 leads .to a pair of cellcontacts 39 and 40, which correspond in po- Sition with the cell-contacts 27 and 24. Assuming a pair of cells to surmount the contacts 39 and 40, the current will pass thru said cells to a -pair of upper cell-contacts air 41 and 42, which correspond in position with the cell-contacts 28 and 25. From the contacts 41 and 42, a conductor 43 leads to a central contact 33 which, it will be understood, is disposed below the lower side of the bottom of the cell-holder. The contacts 32 and 33 should be understood to be so positioned beneath the bottom of the cellholder as to make contact, respectively, with the contact-ring 5 and the central contact 2 of the lantern-casing.
For most purposes, the cell-contacts carried by the cell-holder, mounted ,as they are on the projecting ledges ati'orded by the top and bottom walls 12 and 14, will serve to hold the cells in proper position while the cell-holder is being introduced into the container A or removed therefrom. If desired, however, the cell-holder may be vequipped with any suitable additional cell-retainer, such as the iexible member 44 which engages the hooks 45. Such a retainer may be drawn about the cells on either side of 'the division wall 11 after the cells have been inserted.
In practice, the cells are preferably inserted with the bottoms of they zinc containers resting on the lower cell-contacts and the carbon poles engaging the upper cellcontacts. The cells may be inserted in inverted position if desired, however.
The improved cell-holder is adapted to receive flash-light cells of standard construction, vno alterationv or special provision With relation to the construction of the cells being necessary. Moreover, thel improved cell-holder affords a support for the cells at both top and bottom, and the cells may also bear against the vertical walls of the cellholder and against each other, so that they are quite securely nested. It will be understood that the cell-contacts of the holder preferably are so spaced with relation to the vertical walls of the cell-holder as to correspond with the vertical axes of the cells when the cells are introduced.
