Be-it known that I, Couarneun Seems,

a citizenr'of the United States, residing at Sharon; inthe county ofMercer and State of Pennsylvania, haveinvented certain new and useful Improvements in Hidden Switches for Coil Boxes; and I do declare the following to be a 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-thesame.

This invention relates to an improved construction in coil boxes and one object of the invention is to soconstruct the coil box that a switch which in the form shown will be a. key-operated lock, may be provided beneath the flooring board of: the coil box where it cannot be readily found, this switch being operated. by means of a key the bottom of the coil box so that it cannot be readily discoveredwhat is wr he; with the ignition system when an unauthorized person attempts to start the automobile,

Another object of the invention is to so construct the switch. that it may be posl-. tioned betweentwo contact elements, one of which is connected with the conductor strip which engages the coil unit in thebox and so the other of which will be connected with the circuit of the signal horn between the horn and control switch thereof so that when this contact is engaged by the bolt element of the ,lock and the usual switch 85 of the ignition system is turned on, the signal horn will be hounded and continue to operate. v

Another object of the invention is to so construct this device that a conventional structure of coil box and flooring board for the'same may be made use of, the conductor wire leading from the terminal for the source of energy being connected with the lock which constitutes the switch element instead of with the conductor strip carried by the flooring and engaging. the coil unit. This invention is illustrated in the accom panyingdrawings, wherein: I

F inure 5 is a sectional view taken along the line 55 of Fig. 2 with the switch moved to engage the contact of the coil unit ehgaging conductor. strip.

Figure 6 is a sectional view taken along the line 6-6 of Fig. 41-. I

The coil box B is of a conventional construction for carrying the coil unit C and will be provided with the usual terminal T with which the wire leading from the mag neto or other source of power M will be connected. This coil box is further provided with the usual flooring board F which carrice the conductor strip- S, the conducting strip extending longitudinally of the floor board for contact with the coil unit in the usual manner. The wire 1 which extends from the terminal T is usually positioned in a groove floor board and is connected with a terminal 3 of the conductor strip 8 but with the present construction, this wire 1 will be positioned in a groove l which extends diagonally across the under'face of the floor board and will have connection with a lock 5 formed of conducting material and constituting the switch element. This lock or switch as it may be termed is secured in a seat formed in the underface of the floor board and has its intermediate ortion extending into apocket 6 formed in the floor board. The hick shown is of the key-operated type and will be provided with a guide pin 7 which extends'through a key-hole 8 formed in the bottom of the coil box so that the key indicated by dotted lines in Fig. 3 can be easily guided into the proper position for entering the key-hole and lock. With the key in place, the bolt element 9 of the lock can be moved to the position shown in Fig. 4 or to that shown in Fig. 5 and the key removed thus leaving the bolt element of this lock in the adjusted position desired,

2 formed in the under face of the terial such as sheet rubber or any other.

suitable material is placed in the coil box beneath the floor board so that a short circuit between the lock and the bottom of the coil box will be prevented. The conductor strip S is in engagement with a. contact strip 11 which extends transversely from the conductor strip into the pocket 6 and has its free end portion bent to provide a depending arm 11 positioned in the path of movement of the formed of flexible material and therefore the free end ortion may be moved from the position of -ig. 1 to that of F ig. 2 against the action of the spring 12 when engaged by the bolt element 9. This spring 12 will therefore serve to hold the depending end portion of the contact strip in close engagement with the bolt and provide a good contact between the bolt and strip when the bolt is projected to the position shown in Fig. 2, so that the circuit will be completed through the coil unit. A contact 13 which is of a conventional tongue construction is secured in the pocket 6 upon the opposite side of the bolt or switch 5 and in the path of movement of the bolt 9 so that when the bolt is in the position shown in Fig. 1, it will contact with this contact 13 a The horn H will be grounded as shown at G and will be connected with the magneto by means of a conductor wire 14, a switch 15 of a conventional structure being provided intermediate the length of this wire 14 so that the horn may be operated whenever desired. The usual ignition switch 16 is also provided and will be connectedwith the terminal T by means of the usual conductor wire 17 and will be connected with the wire 14 between the switch 15 and magneto b means of the usual conductor wire 18. wire 19 leads from the contact 13 and is connected with the wire 14 between the switch 15 and the horn so that the horn may be operated and caused to sound a warning when an unauthorized person attempts to start the automobile by closing the switch 16 or placing a bridging wire from the wire 17 to the wire 18. From an inspection of Fi 1 and 2, it will be readily seentha-t when t e lock or switch 5 iso rated by an authorized person and the ho t element 9 moved into engagement with the contact of the conductor strip S, the circuit through the conductor strip will be completed and therefore when the switch 16 is closed, the current from the magneto may terminal T and through t 0 wire 1 into the switch 5 and from this switch to the contact of the conductor strip S and thus up into the coil unit. If however MI-UDMIthOI'iZOd person attempts to start the automobile by closing the switch 16 with the bolt 9 in the position shown in Fig. 1, the current will bolt element 9. This strip is 11$ through the pass through the switch 5 to the contact 13 and through the wire 19 to the horn thus causm the switch 16 is closed. This will give warning that the car is being tampered with by an unauthorized person. It will thus be seen that there has been provided an improvement in coil boxes which will prevent the car from being started by an unauthor ized person.
