SWITCH LOCK Filed May 6, 1929 2 Sheets-Sheet 2 .P 1'Offen By ao/Zih Attorney Patented Apr. 1, 1930 PATENT OFFICE VLADIMIR V. PROFFEN, OF SEATTLE, WASHINGTON SWITCH LOCK Application filed May 6, 1929. Serial No. 360,842.

The present invention relates to a lock for the starter switch of automobiles and the like having for its prime object to provide a means for locking the starter switch against use by unauthorized persons.

Another very important object of the invention resides in the provision of a switch lock of this nature which is simple in its construction, comparatively inexpensive to manufacture, easy to apply, easy to manipulate, not likely to easily become out of order, thoroughly eflicient and reliable in use and operation.

With the above and numerous other objects in view, as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a side elevation of the lock showing the same on the starter switch.

Figure 2 is a sectional View taken on the line 22 of Figure 1.

Figure 3 is a top plan view of the device,

showing the cover plate removed.

Figure 4 is a longitudinal section there through taken substantially on the line 44 1 of Figure 3.

" be seen that the numeral 5 denotes an arcuate or semi-circular jaw, outwardly from the center of which is a handle 6. Radially from the ends of the jaw 5 extend ears 7. Bars 8 extend at right angles from the ears 7 in an opposite direction to the handle 6 and has stops 9 intermediate their ends and stops 10 on their ends. Ratchet teeth 11 are formed on the bars between the ears 7 and the stops 9.

A casing is denoted generally by the letter C and comprises a bottom 12 with side walls 14 rising therefrom, an end wall 15 rising therefrom and an end wall 16 rising therefrom. The end wall 15 has an intermediate arcuate or semi-circular jaw portion a with radial end extensions 5 formed with notches 17 to slidably receive the bar 8. Ears 18 extend inwardly from the side walls 14 and have notches 19 to receive the bars 8 between the

stops

9 and 10. Arms 20 extend inwardly from the end wall 16 and diverge from each 0th or and have attached thereto the ends of spring shanks 21, the other endsof which terminate in pawls 22 normally engaged with the ratchet teeth 11 to prevent the bars from being pulled outwardly from the casing. A spring 23 impinges against the pawls to normally extend them apart and hold them in engagement with the teeth 11. Loops 24 are formed on the inner sides of the pawls and having inclined portions 25. A slide 26 is mounted in the casing and has oppositely disposed arms 27 with upstanding fingers 28 within the loop or frame 24,- so that when the slide is pushed toward the wall 15, the fingers engage the portions to swing the pawls toward each other and out of engagement with the ratchet teeth 11. The slide 26, by means of a spring 30 is held in abutment with a lock 28 of the key operated type and formed with an eccentric cam 29. Obviously by putting the key in the lock 28 and turning it in the direction of the arrow 31 in Figure 3, the cam may be brought into engagement with the slide 26 and move it toward the wall 15 for moving the pawls 22 out of engagement with the ratchet teeth 11, so that jaw 5 may be moved away from the jaw a. Springs 33 are disposed about the bars between the ears 18 and the stop 9, to push the jaws a and 5 apart automatically when the pawls 22 have been disengaged from the ratchet teeth 11. A handle 34 projects outwardly from the wall 16 of the easing 15. The cover plate 35 is fixed on the a casing 3 and has its

lugs

36 and 37 disposed in

notches

19 and 17 respectively for holding the bars firmly in place.

From the above detailed description it will be seen that by turning the look so that the jaws 5 and a are in sepa 'ated condition, the lock may be placed over the head 38 of the switch of the device 39 and then the jaws may be moved toward each other and the ratchet teeth will be engaged by the pawls to prevent the jaws from being moved apart until the pawls are released by the lock. Thus when the device is positioned in this manner, it is impossible to depress the head and it therefore makes it impossible to operate the starter in the usual well known manner. In this way the person when leaving the car parked for any length of time may prevent unauthorized persons from using the car.

It is thought that the construction, utility and advantages of this invention will now be quite apparent to those skiiled in this art without a more detailed description thereof.

The present embodiment of the invention has been disclosed in considerable detail merely for the purpose of exemplification, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction and in the combination and arrangement of parts may be resorted to, without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

I claim:

1. A device of the class described comprising a jaw, a pair of bars extending from the jaw, a casing, said bars being slidably mounted in the casing, said casing having a wall forming a jaw, pawls in the casing, ratchet teeth on the bar, means normally urging the pawls into engagement with the ratchet teeth, said pawls having spring shanks, means for anchoring the spring shanks in the casing, a slide, key actuated means for moving the slide, frames on the shank, arms extending from the slide, and having fingers engaged in the frames so that movement of the bars will cause disengagement of the pawls from the ratchet teeth.

2. A device of the class described comprising a aw, a pair of bars extending from the jaw, a casing, said bars being slidably mounted in the casing, said casing having a wall forming a jaw, pawls in the casing, ratchet teeth on the bar, means normally urging the pawls into engagement with the ratchet teeth, said pawls having spring shanks, means for anchoring the spring shanks in the casing, a slide, key actuated means for moving the slide, frames on the shank, arms extending from the slide and having fingers engaged in the frames so that movement of the slide will cause disengagement of the pawls from the ratchet teeth, spring means associated with the bars to normally hold the jaws separated.

3. A device of the class described comprising a jaw, a pair of bars extending from the jaw, a casing, said bars being slidably mount ed in the casing, said casing having a wall forming a jaw, pawls in the casing, ratchet teeth on the bar, means normally urging the pawls into engagement with the ratchet teeth, said pawls having spring shanks, means for anchoring the spring shanks in the casing, a slide, key actuated means for moving the slide, frames on the shank, arms extending from the slide and having fingers engaged in the frames so that movement of the slide will. cause disengagement of the pawls from the ratchet teeth, spring means associated with the bars to normally hold the jaws separated, a handle extending outwardly from the first mentioned jaw, and a handle extending outwardly from the end of the casing remote from said jaws.

4. In a device of the class described comprising a jaw, a pair of bars extending from said jaw, a casing, said bars being slidably mounted in said casing, said casing having a wall forming a second jaw, pawls in the casing, 'atchet teeth on said bars, spring means normally urging the pawls into engagement with said ratchet teeth, a spring pressed slide member mounted in said casing, an operating connection between said slide member and said pawls for urging said pawls out of engagement with said teeth against the action of said first mentioned spring means, and key actuated lock means controlling said slide.

In testimony whereof I afiix my signature.
