Application filed September 20, 1915. Serial No. 51,543.

. ticularly for motors for vehicles and boats.

In starting motorsit is customary to turn the switch to'the battery for preliminary sparking, and then when the motor is running,'-it is switched to the magneto. It is also desirable at times to lock the parts in such a postion that the motor can not be tampered with, or operated by a person other than the owner or an authorized employee, when the owner or driver leaves the vehicle in a public thoroughfare for any purpose and hence the machine can not be stolen or used surreptitiously.

The object of this invention is then-primarily to provide a simple arrangement of switch mechanism and locking means which is positive in action, and one in which the parts can be manipulated to cut out the sparking mechanism.

With this and other objects in view my invention consists in certain features of construction, arrangement and combination of parts as will be hereinafter described and pointed out in the claims, reference being had to the drawing in which- Figure 1 is a face view .of the device as applied to the dash of an automobile or motor boat. Fig. 2 is a vertical section of same on line 22 of Fig. 1. Fig. 3 is a bottom plan view. Fig. 4 is a vertical section on line 4-4 of Fig. 2. Fig. 5 is a vertical section on line 55 of Fig. 2. Fig.

6 is a detail'perspective view of the auxiliary switch lever. Fig. 7 is a detail perspective view of the .bolt device. Fig. 8 is a perspective view of the tumblers and accessories used in the combination or permutation locking mechanism. I

- Referring more particularly to Fig. 1, it will be seen that I provide a casing A secured to the dash B by screws or otherwise, and having the front face A made as a dial. Within casing is a back plate C? faced 'with-insulationC all held to the dash by a screw as shown. A switch D"of the double-throw. type is mounted to swing on pivot D forming a binding post to which the conductor E is clamped; this double-throw switch comprises the lever D and the curved knife blade spring arms I) designed to be swung into contact with the contacts D, D connected at the rear of the insulation with the conductors D, D running to the battery and magneto respectively. The back plate C has an opening through'which the binding post passes but not in contact therewith. The back plate C also has a hooked arm '0 passing through the insulation above the binding post and a slotted arm or stud C at its base, the purpose of whic pear. The casing is divided into two compartments by a partition F fitting within the casing and securely fastened to disks therein, said partitionhavin a central elongated slot F through whic a pin G- fastened to bar G" projects said pin beingsecured to the upper end of an auxiliary switch lever G having a downwardly pro-.

jecting hook G at its upper end, another hook Gr near.its lower end a slot G above the lower hook in which may play the pin or lug l)? on the front face of the doublethrow lever D the auxiliary lever passes downwardly through a slit A in the casing, said slit having an enlarged central portion as at A At the extreme lower end of the lever, a handle G is provided. Projecting forwardly from bar. G is the bolt mem-' ber G A spindle A projects through the front of the casing and is secured to a spacing ring A; the spindle has a longitudinal groove a in one face in which fit the teats H L O and Q in the central openings of disks H. L. O. and Q. shown in Fig. 8; separating these disks are the disk rings R having slots R and the disk S having a slot S to register with the notches R in the rings R. The disks H. I. M and P. having notches H ,I"M and P while the disks I J K M N and P have pins I J 2 K M N and P projecting laterally from one face which are designed to engage projections J K. L N and shoulders O and Q, on the disks J. K. L. O. and Q respectively. On the outerend of the spindle is placed a milled head T for manipulating the tumblers of the lock and ahand or pointer U is secured to the spindle will later ap-' lever in the position shown in dotted lines in Figs. 2 and 5 to the lock, pull the aux-' iliary lever back in slitA to the center at largement and let it drop, the hook G catch ing on C? and the hook G dropping into slot in 0 give the knob of the spindle a few turns and the combination. is on. To open, turn the knob until notch I registers with the slot R in the adjacent ring R; then in an opposite direction until the slot in the next disk M registers with the before-mentioned slots and so on till all the slots in the disks and rings are in alinement, H being the last and this being brought about by projections and pins on the several disks contacting; when the slots are all in registry, the auxiliary lever can be raised, freeing the hooks G and G and carrying the bolt G into the space made by the alined slots; the lever G? can now beswung to either side and carrying the double-throw lever with it and will contact with either the contact of the batteryor magneto depending on which side the auxiliary lever is swung.

The disk S supports the spindle at the rear-and separates the tumblers from contact with the other part of the device. The hooks G and G also prevent lock from. being taken from the dash of the vehicle when combination is on as it locks casing to back plate, which is itself fastened to dash by screws from the inside.

I claim 1. A combination switch lock comprising a casing, a double throw switch arm mounted therein, and contact plates over which said arm may be turned, a spindle ournaled in the casing, tumblers within the casing and mounted on said spindle, and controlled thereby, an auxiliary switch lever slidably and pivotally mounted in the casing, means for coupling the said auxiliary lever with the throw switch arm, and means pii otally carried. by the auxiliary lever for engaging the aforesaid tumblers and operatively coupling the auxiliary lever with the spindle, whereby the throw switch arm may swing into contact with either a battery or magneto circuit.

2. A; combination switch lock comprising a casing, a double-throw switch arm mounted therein,'contact plates over which the switch arm may be turned, said. switch arm having a forwardly projecting pin, an auxiliary switch lever mounted in the casing, said lever having a slot adapted to be en gaged by the pin on the throw lever, a spindle rotatably monnted in the casing, tum-- blers within the casing'controlled by said spindle and means for operatively' coupling the spindle with the auxiliary arm eby thethrow lever may be swung a contact with either a battery or magneto circuit,

3. A combination switch lock comprising ET,

,on the double-throw switch arm, an arm pivotally suspended from the auxiliary lever, a bolt projecting transversely from said arm, a spindle rotatably mounted in said casing, and slotted tumblers rotatably mounted in the casing and controlled by said spindle, whereby the bolt may be brought into the slots when in register and permit the auxiliary lever to be swung to move the double-throw lever into contact with a battery or magneto circuit.

l. A combination switch lock comprising a casing, a back plate, three posts mounted in said back plate, contact plates connected with two of said posts, a contact lever arm mounted in the casing and adapted to be swung from one contact plate to the other, said arm having a forwardly projecting pin, aback plate having forwardly projecting upper and lower lugs, the upper lug having a hooked end and the lower lug having aslot therethrough, an auxiliary switch lever slidably mounted in the casing having rearwardlv projecting hooks adapted to engage the aforesaid upper and lower lugs and provided with an elongated slot to receive the pin on the arm of the throw lever, when in oil positi0n, an arm pivotally engaging the auxiliary lever, a bolt projecting forwardly from the lower end of said arm, a spindle rotatably mounted in the casing at the front thereof, rotatable tumblers within the casing controlled by said spindle, said tumblers having slots adapted to be brought into alinement, whereby the bolt may bemoved into said slots and permit the auxiliary switch lever to be slid vertically, and swung to the right or left to cause the doublethrow lever to contact with the battery or magneto circuit.
