IGNITOIT LOCK.

Application filed Marcio i4,'192l.. Serial No. 452,175.

To all whom t fnv/oy concern it knovn that l, lifronon l" armas, a citizen ot' the United States, residing at the city olI ijleasantville, county ot Atlantic, and imitate oit lieiv Jersey, have invented a certain nen4 and useiiul improved ignition Loek, olf which the 'following is a speciiication.

r.llliis invention relates to an ignition lock and has more especial relation to an ignition lock for use upon motor vehicles.

The leading object ot the present invention is to provide an ignition lock adapted to prevent the uiniutliorized starting' ot a motn' vehicle. engine. A further object is to provide a lock olf this character which may be applied to the dash-board or some other appropriate part oi a motor vel'iicle the parts being so arranged that the device can only be operated by a person familiar With a given cipher, key or combination speciiic to a selected device. @ther and 'l'urther objects relate to the provisionot gene 'al combinations, arrangements and connections of parts tor accomplishing the results sought by the foregoing objects.

The invention consists of the improvements hereinafter described and iinally claimed.

yThe nature, characteristic features and scope ot the invention will be more fullyv understood 'trom the following.' description taken in connection with. the accompanying drawings forming part hereol, and in which:

Fig. l, is a View in horizontal, central section of a device embodying features ot the invention.

Fig. 2, is a view in crosseseetion taken upon the line 2N2 of Fig. l.

Fig. 3, is a similar view taken upon the line 3--3 of Fig. l.

Fig. 4, is a tace vienT of the device, and

Figs. 5, 6, 7 and 8, are views in elevation of details of construction hereinafter referred to.

For the purpose ol illustrating my invention, I have shown in the accompanying drawings one term thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable result-s, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invenM tion is not limited to the precise arrangement and organization of the instrumentalities as `herein shown and described.

ln the drawings, l() designates a casing of any desired material and preferably of annular configuration. This casing in pracd tice is fitted. Jfor instance, to the dash-board of motor vehicle. Fixed within said casA ing at one end thereof, as by screws ll, is a terminal block l2 of insulating material, as liber. Fitted to such block are terminal. posts i3, 14, l5, 16, 16 and 16, see Fig. 3, of which i3 mav be connected to a magneto, lli to lground, l to a battery and 16 to a. timer, in what is termed a straight sysm teni and 1.6 and 16 connected to coil and magneto respectively in a dual system. llotatably mounted Within the casing is a spindle 17 provided' at one end With a switch 18, tor bridging tor instance, contacts lil-1.4; or 1 5-16 in a straight system at the proper time, and provided at its other end with an operating handle 19. This sivitchot course is insulated from spindle i7. Fixed to soindle-l7 is an annular member 20 provided With a plurality of radially di posed channels 2l, see Fig. 3. Concen ti'ically arranged with respect to member 20 and removably fixed to easing l0, as by a pin 22` is a ring 23. rlhis ring is also provided with a plurality of radially disposed channels 2t in register with channels 2l, see Fig. E. tipi-ing pressed endivise shittable bolts 25-26 are present in the channels 21-2/l-, the functions ot which will presently appear. Bolts are cylindrical and bolts 26 are also cylindrical but cut away as at 27 as clearly shown in Figs. 7 and 8. Ring 23 is provided annularly With a plurality of channels 28 arranged at right angles to and intersecting channels 24. Fitted to move endwise through each channel 28 is a plunger 29. Normally each plunger 29 engages with a bolt 26, see Fig. l, to interlock member 2O with ring 23 thus preventing movement oil spindle 17. It is to be noted that the cut-away portion 27 of a bolt 26 passes through cut-away portion 30 of a plunger 29, and that the beveled part 31 of a plunger 29 engages the beveled part 32 of a bolt 26, see Figs. l and 3. The bolts 25-26 are arranged according to a prescribed cipher, key or combination specific to each device. For illustrative purposes, (see Fig. 3) three plungers 29 are required to he operated loefore spindle 17 can be moved. Theseare the plungers opposite the graduations .5G-l0, 70m-14A and 2:3-5 as shown in Fig. 4:. ln this connection it will be noted that bolts 25 complemental to said plungers project between member 2O and ring 23 while in all Lother instances, bolts 25 and 26 abut at the division line between said iember and ring. Thus if the proper plungers are depressed, bolts 26 shift bolts 25 against springs 33 a sulicient distance to permit member 2O to be rotated. However depression ot incorrect plungers serves to move bolts 26 into member 2O thus preventing movement of member 20. lvlcvement o'l' plungers 29 is accomplished by means olf a spring pressed linger piece 8e, movable through rotatable cover plate By progressively moving cover plate so the linger piece 34e comes opposite the proper combination numbers and pressing the linger piece to engage and move the proper plungers, bolts 26 are caused to function properly for the release ot' member 20. 36 designates a housing carried by cover plate which guides the stem 37 of linger niece and also encloses spring 38 thereof. lt also l'oi'ins a bearing for spindle 17. the spindle may be moved so that switch 18 may bel caused to bridge contacts lS-laL or in other words battery and timer contacts. lt will be understood that in this position ol.Z the switch that the previously pressed plungers remain so positioned and Ythat with the return ot the switch to bridge contacts H16 (magneto-ground contacts) means must be present lor returning said plungers to original position. lli description oit such means will now be given. Movably mounted with respect to member and riip; 3 and also movable with respect to spindle i7 and in concentric relation therewith is a disc 39 peripherally provided with .spaced lugs having inclined surfaces 40. Disc 39 is provided with a pin Lll as is ring 223. (onnecting these pins is a rolled spring 4t2. Carried by cover plate 35 is a pin i3 adapted to engage with pin il when cover plate. by means ot linger piece 34, is moved iii the proper direction and move said disc so that the inclined surfaces 40 of the lugs ol' said disc engage beneath the inclined surface 44. oit the plunger heads and restore them to normal position.

lVith the release of member 20,

Leasess Obviously Vthe bolts 2li-26 return `to normal f position by means of springs 33. The disc 39 is slotted as at to permit of said movement. ySpring ft2 returns disc 39 to normal position. Should an unauthorized person invention and the above description andv while have iii the present instance shown de cribed the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modication in various particulars withoutl departing from the spirit or scope of the invention or sacrificing any of its advantages.

What I claim is:

l. In a device ot the character stated, a rotatable spindle, a member provided with radially disposed channels fixed to said spin` dle, a' liXed rino' concentric with said member provided with channels in register with the channels of said member, spring-pressed pairs of bolts located in said channels lfor a predetermined interlocking of said inem` ber to said ring, a plunger'complemental to each set of bolts for operating the same and rotatable means including a' depressible finger-piece for selectively operating predeter` mined plungers to release said member.

2. A construction as described in claim l, characterized by means for returning said plungers to normal position.

3. A construction as described in claim l.7 characterized by a casing for inclosing said member and ring said casing being provided with a cipher, key or combination for determining the proper plungers to be operated.

4l., A construction as described iii claim l, characterized by at least some of said pairs of bolts being arranged to prevent movement ol.I said member upon depression of plungers coniplemental thereto.

In witness whereof, l ,have hereunto signed my name.

GEORGE M. WALTERS.
