Application iled October 4, 1921. Serial No. 505,431.

To alle@ from t muy concern Be it known that li'rnris C. BRYAN, oi

Syracuse, in the county of Gnondaga, in the State of New York, have invented new and useful Jimprovements in v which the following", taken in connection with the accompanying` drawings, is a full, clear, and exact description.

This invention relates to a lever lock` but? morev particularly to a device 'for locking the gear shifting levers ot motor vehicles to reduce the liability ot theft and other unauthorized use ot the machine.

These levers are usually tulcrumed by "a universal joint upon la suitable supporting vbase or housing on the frame of the ma-v distance below thefulcrum and holding said lever in its neutral posit-ion against initial lateral movement in either direction. Y in other words. l havesought to incorporate in the base or housing a more compact and sturdy locking' device than has hereto'- i'ore been piacticed by the use oi a locking' bolt having onrejend eng-aged with'opposite sides ot the lower endroi the lever and its other end slidable in suitable guide' in the base and held in its lockingposition by a ball tumbler controlled. by a key Loperated barrel y v y Another object is torenable the various parts of the locking device to be assembled pr removed without disturbingjithe shitting ever.

Other objects and uses relating to specific I parts of the locking` ydevice will Vbe brought out in thefollowing' description: 'i ln'the drawings: ,y

F l is a detail sectional view taken in the plane or' line e-Ll, Fig. l'showing the means for llockingl one of the clamping bolts of the lever-support against removal from the transmission gear-case. Y

As illustrated, this device comprises-acne.- piece hollow castv metal base or housing 1- adapted to be secured 'inV any well` known mannerto the frame orP the machine and provided with an upright conical portion -2- having a central spherical seat or bearing- -B-in its upper enda which is milled externally for receiving a 'sheet metal` cap lt Y A gear shifting' lever--'f is extended vertically through a central opening -6-`- vin the top of the housing- +1- and is provided with a substantially 'hemisphericalenlargement A7 normally restingf'on the a universal j oint-to permit the lever to swing in' any direction about spherical bearing. l

The hemispherical enlargement` -7-4- is *y intermediate the ends but preferably nearer the lower end of the lever 5fs'o that the upper end of' said lever extends a considerable distance above the top of thehouslng and constitutes the handle by vwhich said 4provided with annular enlargements* -9-f rande-10#-V in vertically spaced relation one above the other betweenl the lower'spherical end '-11- and 4enlargement 7-, the annular enlargement -9- being provided with longitudinally convex surfaces for enf the center of 'the V spherical seat -3- andforming therewith I @agement with the locking bolt hereinafter Y described, .while the annular enlargement lO- is disposed in a'plane just below the locking` bolt to prevent vertical withdrawal oi the llever from its operative position.:

The upper iend of thek cap -74-4* isfspherf ical and provided vwith a central .opening -l2----k of 'suiiicient'diameter to permit the desired 'rocking movement lof the lever 9 5-, said opening beingv closed. by a supheldv against said face by means of ka'coilspring 5-14-1@ interposed= between the sup plemental cap l3 and upper 'aceot the annular enlargement as shown in Fig. 3, -said supplemental cap being' provi ledV with a central openingY l5 or" just surficient size to easily receive the adjacentportion of the lever 5 and'to move therewith as the lever is rocked about the center of the spherical bearing 3 The lever locking device comprises a locking bolt l6 having a cylindrical 'shank 17 slidable horizontally in a radial guide opening l8 and provided withga forked inner end forming a slot i9 eX- tending transversely or' the axis of said bolt in the 'horizontal' plane off thcannular enlargement 9- oi' the lever 5` the ope posite walls of the slot being` stra-ight transversely and extended some distance to opposite sides of the axis or" the lever for ing opposite faces of said. enlargement, whereby the movement of the lever laterallyV in opposite directions will move the locking' bolt l7 axially in reverse directions.

' {n thenther hand, it the locking' bolt isheld against axial movement, it will also hold the lever 5 against lateral nievementor in its neutral position. The shank ofaeloclring bolt is provided'with a lengthwise key-way in one side engaged Aby a key 21 on the inner` end of a screw 22 which engages in threaded aper tureY in therorresponding side of the housing 1 for holding' the locking bolt against turning movement *in the bearing Y 18- and thereby maintamine,l the inner' U-sliaped head in a substantially horizontal position "when the locking bolt is adjusted for use. I i

YThe opposite side of the shank of a locking,- bolt Vis provided with a 'vertical groove M adapted to receive portion of a' locking' ball 25 which is movable in Aa Aguide opening; 26 leading radially fromv the bearing l8 to Van upright opening 27 in which latter is mounted a barrel 28 forininff an extension v of a 'key-lock 29 which in turn is rigidly secured in a socket 30 in the upper endet an olfset portion 31- of thebaseqor housing 1 as shown in Fig. 2.

The adjacent ends of the barrel 28 and the locl; Y 29 areV provided with tongue and groove [connections for `transmittinej motion for theturnable inemmovable into andl out of re ejistrationY with the recess 26 inthe `shank of the 'locking bolt l6 as the barrel 2-8- is turned through the medium ot' Vthe key 33 These recesses 2G andV 34tshifting the Oears. :3 The distance between I j Y 5 and recess 24 alongV the axis Y i j y Y Vineeaoe are oit suficient length-to receive portions of substantially the same .diameter as thatv of tl e passage 26 with'just suliicient clearance to permit the ball to move in'said passage without excessive friction. l Y

The dist-ance between the periphery of the cylindrical shank 17 of the looking` bolt 16- and inner wall ot thefreeess 7 31l Dall to allowsaid ball Yto clear theperijmery f the shank l8 when entering. the

tingl the Vtree endwse movement ofthe l'oclrine; bolt by the action of the lever` 5 in the" center Vor"- the lever ot the locking` bolt is substantially equal to the distance between the vertical axis `o the the guidev opening 26- 'V Vttor -the- 'ball s slightly greater than the diameter'or" the Ythe ball-locker tumbler 25 which Vis of recess alined tberewithjthus permit.-` L

25 and'. it therefore 'followsthat when the lower end of the lever is vlorought t0 il Ybarrel 28- through the mediiimroffthe' key one-quarter turn in either direction or su'flicient to move the recess M out or" rep'istration with the `guide opening' 2G whereupon the periphery ofthe bar`- i rel 28 'at its junction Vwith the inner wall ot the recess' 311- will act as a` cam for forcing the ball 25 into the registering recess M of the locking bolt for locking and holding` the lever in its neutral position, whereupon the key 33 be removed 'by the operator to preventpthe operation oitV the shifting lever and parts'aetur ated thereby.

f VOn the other hand,l by reinsertinp; the keyv u and tu'r'ningthe' in the lock 29' Y barrel- 28 vto bring its'recess M into registration with the ball 25 allows the lockingbolt l6 to be moved endw-ise by the lever during which` operation7 the' lend walls ofthe recess 24L will force the ball 25 into the recess 34. out of the path of movement of said locking bolt.V s p VThe annular flange or enlargement 10%- on the lower end of the lever 5 'normally lies in a plane just below the Linner end of theloclzing bolt 16 and serves to; prevent upward displacement of the lever' from its operative position.

The inner U-shaped end ofthe locking bolt lt is offset normally belowthe axis e 'of the shank 17 to facilitate the removal Y andreinsertion Vof said locking bolt without.-

removing; the shift-ing lever 5 3 this being,- accomplished by'siniplv nnscrewing the isc the Ylashaped end of the locking bolt and Y lto one side of the shank thereof, whereupon `said locking bolt `may be Withdrawn inwardly; and removed from the underside of the base when the `latter is detached from the frame. Y l 5 The spring 14ein addition to holding the member -13 againstthe 'inner face of the cap ll also bears against the upper flat face of the-part w-7-- andserves to yieldingly hold the lever '-45- in its neutral position when the bolt -17-- is un locked. l

The lever-supporting base or lhousing -lconstitutes a cover-plate for a transmission gear-case -G- Figure 4l and is clamped thereto by any Suitable number' of bolts as -35- engaging in threaded sock- -36- in the gear-case -G- and passing loosely through openings -37 in the housing -l-, one of said bolts nearest the lock-barrel -28- being provided With a recess -38- adapted to register with a supplemental locking member -39---, which is movable in a radial opening e0- in the Y base or cover-plateiwl* into and out Vof the Cri recess 38- and is also movableinto and out of aI supplemental recess 41- 1n the barrel -2S-, the inner Wall of said recess ,-el serving as a cam by which the locking member 459- may be forced into the recess -38- of the clamping bolt 435- the lock said bolt against turning simulta-L neously With the locking of the sliding bolt 17-yvhich holds the lever -5- against rocking` movement when the barrel 2S- is turned to its rocking lnosition through the medium of the key -33-. i

T his locking of the clamping bolt *-35- prevents malicious removal of the housing -lfrom the gear-case and thereby prevents unauthorized operation of the gearshifting mechanism, thus producing fa double lock to prevent theft of the machine upon which the device is used, it beingvunderstood that the unlocking of the barrel -28-- will simultaneously release the locking bolt -17- and will also release the clamping bolt -35- to vpermit the removal of the housing if necessary.V
