CURRENT RECTIFYING AND CONTROLLING sYsTEM- Application filed April 27, 1923. Serial No. 635,164.
This invention relates to improvements in current rectifying and controlling systems and more particularly tosuch as are adapt able for use in systems for recharging storage batteries,one object: of the invention being to provide a system of the character specified in which the resistance coils shall be so arranged that the greatest possible number of batteries can be recharged by a 110 volt current at the same time and thus insure great economy.
A further object is to provide a rectifying and recharging system in which necessity for the use of an induction coil shall be eliminated and thus obviate difliculties incident to the use of such coil, which frequently owing to bad connections, causes the line to stop charging while the rectifier bulb is still consuming current.
-With these and other objects in view, the invention consists in certain novel features and combinations of partsas hereinafter set forth and pointed out in the claims.
.In the accompanying drawings,.-
Figure 1 is a front elevation'ofan instrument bracket or board and devices asso ciated therewith.
Figure 2 is a rear view of the same showing the arrangement of various instrumentalities. a
Figure 3 is a plan view, and
Figure 4 is a diagrammatic view.
The circuit controlling devices and connections are supported by an instrument bracket or boar jecting shelf 2,.011 insulating material 2 is secured for support: ing a plurality of elQITlBDt-SOI coils 3 of a variable resistance,six such coils being shown in the drawings. These coils are connected with each other in series and respective ends of said coils are connected by con ductors 4 successively with a plurality of binding posts 5 of a segmental series of con' tacts 6. A spindle 7 having a knob 8 is mounted in the "vertical member of the -instrument bracket and carries a switch arm 9 to be moved over the contacts fi for excluding resistance coils'from or including the same in the circuit. A spring 10 may be located on thespindle 7 in'such manner as to cause the switch arm to engage the contacts with yielding pressure.
A socket member 11 (such as a lamp I cated within a closed contai d 1 having a rearwardly pro which latter a sheet of' s0cket) is supported on post 12 secured to the shelf portion of th (an insulating tween said post and the socket member) and said mtmber is provided with circuit terminals as is customary with lamp sockets. The socket member 1-4 which, in the embodiment of the invention shown in the drawings, may be of type inwhich anode and cathode members are 10- ner,tw0 of the e with two of the e instrument bracket,
terminals of which cooperat lamp socket terminals. The-vertical member of the instrument bracketv also supports an ammeter 15 and a push button circuit closer 1'6 and these are includedin circuits as hereinafter explained. The leadingin conductors 1718 of the 110 volt A. C. circuit are connected respectively with binding posts 19 and 20. The binding post 19 is connected by. conductor 21 with 14 and a lower terminal of the latter is connected by a conductor 22 with a binding post block 13 being interposed be- 11 supports a rectifier bulb the upper terminal of the rectifier The binding post 23 is connected by a conductor 24 with-the positive terminal of a plurality of battery cells 25 and the negative terminal-of the battery is connected by a conductor 26 with a binding post 27,the latter being connected by a conductor 28 with one terminal of the ammeter 15. The other terminal of the ammeter is connected by a conductor 29 with the switch arm 9 for the variable resistance or rheostat and one end of the latter is connected by a conductor 30 with the binding post 20 with which the leading-in wire-18 is connected;
loop or tap circuit is provided for ex citing-the rectifier 14 and two cells of the battery areut-ilized for thi loop or tap circuitincluding the push button circuit closer 16.
traced by a conductor 31 from the rectifier to the circuit closer 16; from the latter by a conductor 32 to a binding post 33 and from the latter by a conductor-84 to the battery 25 and connected with the latter at such pointas to include two cells of said battery. It has been found that with the use of a system such as hereinbefore described, we are enabled to recharge a maximum number of battery cells at the same time and that great economy 'in the use of the charging current has been obtained. With the use s purpose,said
This'circuit may be of our improvements, we are enabled to recharge any number of battery cells from 3 to at least 45.
It will be observed that our improved system does not include an induction coiland hence we are enabled to obviate difiiculties encountered in chargin systems employing induction coils,-such ifiiculties often arising by reason of imperfect connections which will cause the line to stop charging while the bulb is still consuming current.
Having fully described our invention what we claim as new and desire to secure by Letters-Patent, is:
1. In a battery charger, comprising an electron tube having a filament and an electrode, and a battery placed in circuit with said tube and a source of alternating current, means for initially exciting the filament from the battery.
2. A batter charging system, comprisin an electron tu e and a battery to be charged placed in circuit with a source of alternating current, said tube having a filament'and an electrode, and means for initially exciting said filament from the. battery to be charged.
3. The method of charging a battery, which com rises connecting said battery in circuit wit a source of current and the electrode and filament of the electron tube, and using the charge remaining in the battery to initiall excite the filament.
4. The met 10d of charging a batter from a. source of alternating current throug a rectifier, which comprises initiating the action of the rectifier by, the charge remaining in the battery.
- and an electron high voltage,
5; In combination, an electron tube having -an electrode and filament, a battery and a main source of alternating current with which said battery and tube are adapted to be placed in series circuit, and means'for connecting certain cells of the battery to saidfilament -to initially excite the same.

7. In combination, a battery to be charged and a rectifyingelectron tube, having a filament and an electrode, means for lacing of alter-' said battery andtube'in. series circuit with a source of alternating current of relatively and means for placing the filament in circuit with certain cells of the battery to initially excite the same by a current of relatively low voltage.
8. The method of charging a batter from a source of alternating current whic comprises placing said battery in series circuit with the source of current, and an electron tube having a filament and an electrode, and placing certain cells-0f thebattery in circuit with the filament to initially excite the same by the charge remaining in the battery. p y In testimony whereof, we have 'signed this specification.
