SWITCH MECHANISM Original Filed Oct. 27, 1926 www Patentedv Oct. 8,v 1929 n. UNITED STATES PATE-NT oFFICEr/ ORVDLLE S. HEiSHEYyOF CHICAGO, ILLINOIS, ASSIGNOR TO HERSHEY MANUFACTUR- JNG'COMPANY, OF CHICAGO, ILLINOISA. CORPORATION 0F COLORADO SWITCH MECHAN'ISM origiai application filed october 27, t v

Thisinvention relates-to a switch mechanism vadapted especially for an automobile .opened without actuation of the lock, whereby the motor may be disabled it also provides for a coincidental operation, in which ,both

the lock and switch-are aHected simultaneously, or nearly so. This actuation of either the switch or lock,- or both, is effected by a ,single means having an optional dual movement.

An exemplitication ofk this invention in a preferred form is set forth in the accompanying drawings,`in the manner following: O

Figure 1 is a longitudinal section through a suggestive lock structure with which is associated the presentV switch mechanism, also shown in section;

Fig. 2 which is a View in eievaubn looking into the switch housing, shows the parts related to break-the circuit in which the switch is interposed; y

Fig. 3 is asimilar view showing the switch moved to closed position; Y

Fig. 4 is a similar view showing the switch moved to a second openposition and Fig. 5 is a erspective view of the vmovable block which orms the cnducting element in the switchv shown in Fig. 1.

The suggestive lock erein shown may be contained within a housing A through which is an. opening for accommodating a column B wherein-is extended a post C connectinga steering wheel with the swiveled running wheels, usually at the front of an automobile.

Secured fast to the post is'a collar D having therein a groove or socketv 6 which may be brought into register with an opening 7 formed in the column. Suitable means for attaching the housing to a fixed art of an automobile-its instrument boar for example, ma be provided.

cludes va bolt 8` adapted to be projected through the column into the socket 6. This bolt 'is yieldingly associated with manipulative means which may take the form of a hollow plunger 9 wherein is accommodated a coil spring 10 which bears with pressure against one end of the bolt.l The outward movement of the bolt relative to the plunger may be arrested by a plate 11 which abuts against one end shoulder of a flat 12 formed in the bolt surface. `A reciprocable movement may be imparted to the plunger by means of a lockcylinder 13 operable with akey (not shown) designed specially therefor.` At the rear end of the cylinder I have shown an eccentric 14 which is disposed within a slot 15 formed transversely of the plunger. With rotation of the cylinder, the eccentric vtransmits an endwisemovement to the plunger whereby the locking bolt is moved toward or from the steering post'C. It is desirable to employ a lock cylinder wherein the key may be inserted or removed only when the cylinder is in one of dtwo rotative ositions, i. e.. either when the plunger 9 is ully advanced or retracted.

Associated with a lock of the general chari acter described is a switch which may be interposed inl an electrical circuit-the motor ignition circuit, for example. Such a switch is preferably contained `within a housing E which may be fastened removably to lthe under or rear side of lthe lock housing as by means of bolts or screws 25. A/s shown, the switch includes a pair of binding posts 16 extended thron h the housing in spaced relation, each post` aving a head 17 which is exposed to lform a contact.` These two contacts are arranged adjacent one face of a chamber within the housing wherein is a movable switch block 18, preferably of 'elongated form, as shown. The chamber lis longer than the block whereby the latter may be reciprocated longitudinally therewithin, and is also enlarged laterally at one end by the oblique extension of one wall 19. Byv this construction one end vof the block may also be swun to one side, as indicated in Fig. 4. This movido Y trally by a /cross sloti'wherein may be seated the crimped central portion of a spring brush 21 the two-ends of which, disposed in the channel, arefadapted to engage with the terminal post contacts 17.. IIt is contemplated that the two posts of the switch shall be interposed in an electrical circuit which is broken when the movable-block 18 is shifted longitudinally to one end of the housing chamber,n

'10 (and closed when moved to -itsoppo'site end vwhere anelectrical connection is established between the tw/ terminals 17. The circuit may also be broken when one end of the mov-- able block is shifted laterally, as in FigJi, so

as to disengage from the proximate contact 17.

l A switch having the general characteristics set forth herein may be' operated by move-1 ment of the plunger 9, the outer end of which' Iis, equipped with a manipulating head 22 produced conveniently as a Yseparate unit. The

operative connectionnbetween` the plunger Y and the movable switch block may consist of.

a pin 23 lwhich is extended laterally from the plunger for loose 'engagement within a socket in the block. Any movements of the plunger, whether reciprocatory or oscillatory, are

transmitted to the block, the effectbeing to erating key. Oscillationsfof the pl ger are I the cross ,slot 15,.'

ei'ected .by manipulation bf its head. 22 to which no opposition is offered by the eccentric 14 by reason'of its sliding disposition within The plunger mayv be yielding held against rotation froma normal position as=by means of any lsuitable detent (not shown) It is desirable, however, to provide for turning normal position of Fig. 2. f

1 plate is formed wit shown)having'o`ne oblique edge correspond- Icharacteristics herein set fort the plunger back to normal in'` case ofl a reciprocation Awhich starts fom the off position ofthe switch, as in Fig. 4. `For this pur-l pose use is made of a guide plate 24 which is arranged in place adjacent the .lock housing within the housin ,E for the switch.
