LOCKING MEANS.

Application fi1edi0ctober 31, 1923.

My invention relates to a combination locking means andis particularly adapted for locking such .mechanisms as steering wheels when not in use, although it will be obvious from the following description that it is adapted for otheruses,

Many locks for steering wheels are so .made asto. loekthe wheel to thesteering post when in use and to. unlock it therefrom when idle. Such locks are dangerous as they do away withthe rigid connection between the steering wheel and post which is essential for absolute safety. .Alsomany locks which are at present inuse require the manipulation of a key torlocking and unlocking with the attendant disadvantages and the danger. of losing the .key and so renderingthe lock useless.

An object of my invention. is to provide a lock which .in no wayv affects the rigid connection between the .wheel. and steering post and which is so constructed as to positively hold the wheehagainst any movement when locked.

. A further object is. to provide. 1 a. simple, POSllZlV6-lOCki of this type which can be easily andsurelyzoperated without the use of keys'of anyj-sort.

Further objects willbe apparent from. the

following description and the accompany .ing drawings inv which I have. shown one ..embodiment of .my invention as applied to asteeringwheel and inwwhich Figure 1 is a vertical section through my locking means showingit applied to a steering post, 2

As illustrated the lock ineludesnt-wo .re-

\ latively movable members land 12 which. are

. adapted tobe moved @into and out of locking position. Each .member. is providcd with .several tumbler receiv ng apertures, a so. ar-

:ranged that each aperture of one. member,

,registerswithan aperture of theothcrmem- .ber..when the members are in. locking" posi ward movement.

,tion. Some ofsaid apertures. are provided with spring pressed tumblers 5 and 5" which are so arranged that they normally form a locking, element, between said members,

when the members are in locking positioin Other. apertures are provlded with manually actuated tumblers, which either control the movement of the spring pressed locking tumblers, or which themselves are capable of locking. the members 111 the locking position. A separate actuating "device, is provided for each manually operated tumbler, and these. devlces are similar in. appearance so as to disguise those which control the movement of the spring pressed locking plungers.

s As applied to as-teering wheel my invention includes a cylindrical stationary memher 1 which is adapted to be rigidly secured to a housing 2 ot a steering postfi. A plurality of circumferential rows of recesses 4. are provided in the cylindrical member. Seated in these recesses are tumblers 5 adapted to .be. springpressed outwardly .by spiral springslorcated between the bases" of the tumblers and the bottomsot the recesses. Certain of these locking, tumblers 5, have greater length than the others, for a purpose to be hereinafter described.

Surrounding the stationary recessed member 1.is a movable keeper sleevefiwhich; is provided with a plurality of circumferential rows of recesses 7 which are adapted to cooperate with the recesses 4; of the stationary member when the keeper sleeve is in its raised position. glVhen the sleeve is lowered its recesses 7 are movedout of line withthe recesses otthe stationary member and the latter are then closed by the sleeve which retains the. locking tumblers 5 and 5 within their recesses and prevents their out- This keeper sleeve is normally pressed. downwardly by a spiral spring 8 located between the top. of the sleeve .and the upper part of my locking means,

and surrounding the top. of the. steering post housing. It is. adapted .tosbe raised to bring itsrecesses into line. Wltllillfl locking tumblers bya button 9 extending through a slot. 10in the lower support 11 of my looking. means.

This lower supporting member 11 is adapted to be rigidly secured to the inner stationary. member 1 and tothehousing 2 for the steering postp lts upper face is of the steering wheel 14 and is adapted to turn therewith. V 7 Located in the recesses 18 which come opposite the locking tumblers 5 are manually operated tumblers 15 of such length as to prevent these locking tumblers from entering the recesses in the locking sleeve. In the recesses 13 which are adapted to come opposite the long tumblers 5 are other manually operated tumblers 15 which are of such length as to allow the tumblers 5 to enter the recess in the outer sleeve when it is in line therewith and when the perforation in the keeper sleeve also registers therewith. All of the manual tumbers 18 and 13 are provided with stems 16 which extend out \vardly through small openings in the circumference of the locking sleeve and have at their outer extremity similar operating means or buttons 17 Assuming that the steering wheel is locked againstmovement'by the locking tumblers 5, as shown inFig. l, and that it is desired to unlock it therefrom in order to manipulate it,'it 'will be impossible to do so unless the operator has knowledgeot what combination of buttons 17 to press to release the the manual tumblers 15 to push back the.

' associated tumbler 5 and enter the recess 4.

in the stationary member 1.

be operated.

7 Obviously any manipulation of the buttons other than the correct combination would fail to unlock the To do so it is essential that only the buttons of themanual tumblers 15 locking tumblers 5 out of tie recesses in the sleeve 12. Upon such movement the keeper sleeve 6 is torceddownwardly by its spring past the beveled ends of the various tum blers, thus closing all recesses and preventing any locking movement of the tumblers.

The wheel is then free to berotated and the car operated. To lock'the wheelit is only necessary to bring the recesses 13 opposite :the locking tumblers 5' and to raise the keeper sleeve by means of the button 9 and when the recesses register the locking tum blersare forced outwardly into locking posi- This will'result in forcing the movable sleeve 12 and the stationary support 11 respectively. 7

It is thus seen that I have provided a secure lock which can be easily applied to a steeringwheel without in any way interfering with its rigid connection to the steering post and that my lock can be easily man1pulated without the use of any keys whatsoever.

In Fig. 6 I have shown my lock as applied to two movable members such, for example, as a door, and its casing shown for simplicity as applied to a sliding door and its jamb.

The lock in this case is similar in all respects to the one'herein above describedwith the additional feature or" having the looking tumblers provided with a means such as rings 18 connected to stems 19 which eX- tend outwardly from the base of the tumblers to allow all tumblers to be pulled back into unlocked position. This enables the door or the like to be unlocked from the in-l side by one who is unaware of the proper combination and also holds each locking tumbler in its recess.

Springs 22 are provided beneath the but tons 17 of each manually operatedtumbler to hold the same in the proper position and to prevent its obtrusion in the way of the door when closing the latter.

Having thus described one embodiment. of my'invention what I claim as new and desire to secure by Letter Patent is:-
