LOCKING MECHANISM.

7 Application filed December 23,1926. Serial No. 156,733.

One object of my invention is to devise a novel construct-ionof a locking mechanism which is adapted to be employed to lock-any desired mechanism,

-Anotherobject of my invention is to devise a novel lock which can be set for any desired key, and wherein the actuation of c an improper key will prevent the unlocking of'the lock. v

Another object of my invention is to at vise a novel locking mechanismbfor automobiles wlnchwlll lock the gear shiftinglever of a motor vehicle 1n itsneutra'l positlon irrespective of the position in which it is.

located, said locking mechanism being preferably controlledby the'opening of a door of the motor vehicle. 1

With the above and other objects in view as will hereinafter more clearly appear, my

invention comprehends a novel locking mechanism.

Other novel features of construction and advantage will hereinafter clearly appear in the detailed description and 'the appended claims. l

For the purposeof illustratingthe invention, drawing a typical embodiment of it, which, in practice, will give reliable and satisfactoryresults. It is, however, to be understood that this embodiment typical only and that the various instrumentalities of which 'my invention consistscan be varig ously arranged and organized, and that the invention is not, therefore, limited tofthe precise arrangement and organization of these instrumentalities as herein set forth. Figure 1 is atop plan view of alocking mechanism, embodying my invention.

Figure-12 is a diagrammatlc view showing -its control by the doorsof a motor vepart s. V

lteferrmg to the drawings 'The supportmg frame work. or housing may 1 vary widely in construction, and for convenience of illustration Ihave shown it as consisting of a casing 1,to which is se-' cured La bottom plate 2 bymeans of rods 3 passingthroughthe top ofth'e casing and inthreaded engagementwith the bottom plate. It will be noticed that these fastening rods 3do not pass through the bot-- tom plate and the casing is counter sunk to receive'the heads of the rods so that molten metal may be poured into cover the heads after the rods havewbeen screwed in a. position so that it is practically'impossible to tell from the appearanceof the casing or together. I j" The locking mechanism is concealed within the casing 1 and is supported on a pair of plates 4 which are fixed to a bottom plate -5 having a longitudinally extending recess 6, see 'more particularly Figure 1'1, in which is mounted to slide in opposite directions the slides 7-. p

As each'slide and its a'djuncts is of the same construction, I have, for the sake of brevity, described in detail the construction of but one of these slidable units.

Referring'now more particularly, to Figure 7, it will'be seen that each of the sliding locking mechanisms consist of a slide 7 in the form ofia plate havinga' predetermined number of apertures 8, the purpose of which will hereinafter clearly appear. Each slide .7 is connected atits outer end to a cross bar .9 to which may be connected, if desired, and in any desiredmanner, an actuatingrod 10.

Each cross bar 9 has fixed to it guide rods 11 which pass through the deflected aperture ears 12 of the guide brackets 13. I

In order to provide for the simultaneous movement in oppositedirections of the slides ner end of which is rounded, and from this.

rounded portion, theopposite side of the walls of the recess diverge toward the end of the locking member 17 as-indicated at 19-;

The slides 7 are retained in position by means of a. top plate 20 which is secured to the bottom plate 5 by means of fastening devices 21, see Figure 1'. The bottom plate 5 has connected with it as illustrated, bottom'brackets 22 through which pass rods 23 which serve as fulcrums for a. series of levers 24 having pivotally connected wit'h them locking pins 25. These levers 24 have piv oted to them at their free ends, the rods 26 which: pass through a line of apertures 27' in the bottom plate 5and the top plate 20, and are connected with the arms 28", from which extend upwardly the pins 29.

These arms 28' are in threaded engagement with their rods 26 and between such arms and the top plate 20 are interposed springs30: which tend to maintain the pins 29 and their adjuncts in. their raised position.

The locking pins 25 of the levers 24, are

adapted to pass through apertures 31 in the:

bottom plate 5* and if an aperture 8, in the plate 7 registers therewith, it will pass through such registering" aperture 8 and retain. a: slide 7 in its. locked position. These levers 24 and locking pins 31, I term. for the purpose of description, as the; bottom locking levers and locking pins.

The. top plate 20 is provided with brackets32 through which pass the rods 34 which serve as fulcrums for sets of top levers 35 having locking pins 36" pivotally connectedto them and adapted to' pass through aper-- tures 37 in the top:- plate 20' and registering aperture 8.

These levers 35 haveconnected to their free ends the locking pins 38 which extend aboveand below their levers so. thatthelower portion is adapted to enter the line of apertures 27 in the top-'plate-20' and thebottom plate 5 respectively.v Between the top plate 20 and the lovers 35. are interposed springs 39 which tend to maintain the looking pins 36 in their unlocked position.

The locking rods 38 have adjustably connected with them the arms 40, and as illustrated, the arms 40 are in threaded engagement. with the upper ends of the rods 38.

The arms 40 are connected at their free ends with upwardly extending pins 41. The

pins

41 and 29 may be called key pins and ing this sleeve is a spring 43, the function of which is.- to eject th'e'- 'key' 44 when the operator removes his hand from the key so that the key will not be retained in the. space 45, see Figure 6, formed by the upward extending apertured' boss ofthe'top face of the casing; 1,; as. will be understood by reference to Figures 2 and 6.

The sleeve 42:. is provided with the ribs 46, see Figures 1 and 2, and the sleeve 47 of the key is provided. with slots 48. Contained within the. sleeve 47 are the key pins 49' which are fixed in a block 50,v secured.

in any desired manner within thev sleeve,

and the sleeve is surrounded by a collar 51 from; which extends a plate 52 which forms. a grasping. handle.

The casing 1 is; provided with anextension.

53 having a tapered opening through it in order to be adapted to' fit over a corresponding' tapered portiono-f the housing 54 of the transmission of the motor vehicle, and" such portionot the transmission housing of the extending casing53, isalpertured at 55- in order to receive the: locking plates 17,. which are adapted to lock the gear shift lever 56 of the transmission in: its neutral position, irrespective of the position to which it has been moved by the operator.

It. is one of the objects of this inventionto provide a locking mechanism. whichv can be controlled by the doors of the automobile, such as, for example, the doors providing access tothe'driversseat, so that the opening of such door or doors will auto matically move the gear shift lever 56 to its neutral-position and lock it in, such position, due to the action of opening the doors through an intermediate. mechanism operatively connected with the actuating moving the slides 7 into such {JOSH/10m that their apertures 8 will register with one or more of the lockingr pins and thus cause the locking mechanism. to be positively locked.

The connect-ing means between the doors 57 and the rods 10 to causev the slides 7 tomove toward each other may vary widely in practice, and for. the purpose of illustration,

I have shown. the doors 57 as provided; with the hooks 5.8, which during the opening movement of a door 57 are adapted to engagethe upwardly extending rods 59, carried by the levers 60 fulcrumed at 61. is connected at one end to a lever 60 and. is: connected at its opposite end to the links 63 A link 62v and 64. The link 64 has a fixed pivot 65;,

and the link 63 is its actuating rod. 10, I

It will thus be seen that if a door, leading to the drivers seat is opened, the hook 58' cooperating with: the rod. 59v will cause the link 62 to bemoved laterally thereby forcing;

a rod 10, its slide and adjuncts, into locking position. The slides 7 are connected tomovef pivotally connected, with.

rods 10,

in unison as before explained sothatwhen one slide is operated it will efi'ect the actuation of the other slide. V

This movement towards each slides 7 into their locking posit-ion causes the locking member 17 to move toward each other so as to embrace the gear shift lever 56 and due to the outwardly diverting walls 19,

it will be apparent that irrespective of the position in whichthis gear shift lever mayhave been moved, this. movement toward each other of the locking- .plates 17. will and its adjuncts, or in other words the unlocking movement of the locking mechanism when the locking pins are released, is due to the provision of springs 66 interposed between the bars 9 and the apertured ears 12 of the brackets 13, these springs belng 'carried by'the'gulde rods 11 as Wlll be clearly seen from Figures 1 and 5-. v

In Figure 10, I have shown the key as arranged for one arrangement,-and if any other arrangement'is provided, it will be impossible to effect the unlocking of the locking mechanism, or it the parts are in thelr locked posltlon and an unauthorized person should press down a key pin 41 which does not form a part of the predetermined arrangement. it will be apparent that a locking pin 36 will enter an aperture 8 in aslide 7 so that the locking mechanism will not become unlocked.

It will also be apparent that in case an unauthorized person uses the key 44:, seen in Figure 10, and in addition a pin which will actuate one of the locking pins 36, that while the lower locking pins 25 would release the slide 7, the upper locking pins 36 would enter apertures 8 in the plate 7 and prevent the unlocking movement of the locking member 17.

If the key pins 49 of the key are of the proper arrangement to contact with the key pins 26, it will be apparent that if the proper key for which the key pins 29 are arranged is inserted. that the locking pins 25 will be released and the springs 66 will cause the bars 9 and their adjuncts to move outwardly thereby moving the locking members 17 into their locked position.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

other of the 1'. The combination with the transmission of a motor Vehicle .and a door, controlling access'to the driVerSseat, oflocking mechanism controlled by the opening ofsaid door and eiiective 'to automatically lock. said transniiission' in its neutral position TFI'QSPQC'.
