Application filed February 9, 1914. Serial No. 817,389.
To all ivkom it may concern: & 3e it known that I, ELMER E. Trims, a citizen of the United States, reslding at -Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Permutation Switch-Locks; and I do declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,'and to the letters and "figures of reference marked thereon, which form apart of this specification. 7
This invention relates to certain new and useful improvements in switch locks to be used in connection with the ignition circuits of automobiles;
The principal object of the invention-is to provide a switch lock that may be utilized tolock the electrical ignition system of all makes of, autoinobiles, thereby greatly extending its utility. t
A further ob ect is-to provide a simple and compact-switch lock which is easily manipulated and comprises comparatively few parts all of which are supported upon the face plate of the lock housing.
To the foregoing ends my invention consists of the parts hereinafter described and claimed.
Referring more particularly to the drawing s, Figure 1 is a rear elevation of the de-- vice showing the casing in section; Fig. 2 is a top plan sectional view partially diagrammatic. showing the switch connected into the well known form of ignition circuit; and Fig; 3 is a front elevation of the complete loo In the specification and drawings, similar reference characters indicate corresponding parts.
The lock maybe mounted on any suitable part of the automobile, preferably the dash 1, a portion of which is shown in Fig. 1, provided with a suitable pocket which re- Drums 6 are mounted on the shafts 5 inside 1 the casings 2, while the finger knobs 7 of the shafts lie in front of the face plate in a convenient position for operation. The drums 6 are given the necessary rotation from the knobs 7. In the present instance the drums ti are made of metal and are, therefore, conductors of electricity. The
said drums being of metal,-the device is,
adaptedto operate on the closed circuit principle. Brushes 8 and 9 are mounted on suitable insulated supports 10 extending from the face plate 3 and engaging said drums. tact with the drums, the ignition circuit, hereinafter described, Will be grounded thereby preventing its operation. To eliminate the ground connections of the ignition circuit, the drums 6 are provided with in sulated, blocks 11 mounted in their peripheries. When the said brushes are in contact with the insulated blocks 11, the ground connection is broken and the ignition circuit is operative. To indicate when the brushes 8 and 9 are in contact with said blocks 11, the drums 6 are provided with peripheral i-iotches 12 in which the ends 13 of the brushes are adapted to snapi The open circuit position of the blocks 11 is thus ascertained by the number of clicks of the brushes 8 and 9 when the drums 6 are moved from normal positions by the knobs 7. The normal positions of said drums are indicated by feeling through the agency of stop pins 14 mounted on the face plate 3 When the said brushes are in con;
and pins 15 mounted on the drums. The
number of clicks necessary to move the drums in order to bring the'blocks 11 in engagement with the brushes 8 and 9 may be changed by setting the pins 15 in any .of a number of openings 16 in said drums. In the present instance. I haveshown three such drums andit is necessary, owing to the electrical connections, to bring all of the insulated blocks 11 in contact with the brushes before the ground circuit will be opened. Consequently, three numbers, one for each drum, must e known to the operator before he can successfully manipulate the lock. It is contemplated that these numbers will only be known to the owner or driver of the automobile thereby preventing the machine being operated by unauthorized persons. The drums 6 are held in their set positions by the ends 1-3 of the brushes resting in the notches 12 but brake-springs 17 may be provided, said springs being mounted between the face plate 3 and the drums 6.
In the present instance, I have shown the lock as connected into a well known type of ignition system which system is known in the art as the Bosch dual system. This system isshown diagrammatically in the lower portion of Fig. 2 in which 18 represents the ground or frame of the automobile, 19 the battery, 20 the coil, 21 the sparkplug, 22 the distributer and 28 the battery timer. The lead wire 24 runs from the battery circuit breaker, while the lead wire 25 is the magneto ground wire. As is well known, if either of these wires are grounded, the circuit becomes inoperative. This expedient is accomplished in my invention through the agency of lead wires 26 which are connected to the lead wire 25 and in parallel'to the brushes 8. The lead wire 26 grounds the magneto circuit, while the batcircuits are broken by the insulated blocks 11.' In completing the ground circuit through the switch the switch casing is grounded through the agency of a lead wire 28. It will be noted that the brushes8 are for the battery, while brushes 9 are for the magneto. It will, therefore, be seen that when a single system is used, either battery or magneto, only one set of brushes will be the periphery of each of said drums, brushes arranged to engage the drums and the insulating members thereon, pins adapted to be set in the concentric apertures of said drums to limit the rotation thereof, and stops arranged in the paths of said pins to arrest themovement imparted to said drums.
2. In an electric switch lock, the combination with the face plate of the lock casing, having a series of laterally extended apertured bosses, of a series of drums mounted on shafts extending through said apertured bosses, each of said drums having its periphery serrated and concentric openings in the sides thereof, a setting pin adapted to be inserted in said openings an insulated block set in the periphery of each drum, brushes arranged to engage the periphery of each drum, and stops arranged in the path of each setting pin to arrest the rotation of the drums in the operation of said drums.
In testimony whereof I aflix my slgnature, in presence of two witnesses.
