The flexible bolt ber 53` is fixed relative to the hand lever 2| by ' in said latter named means includes an elongated flexible member. the strap 55. The keeper 68 is tightly clamped 3. As a new article of manufacture, a locking means for connection to a ~hand brake and for on the gear shifting rod i9 in a position whereby the rod I9 may have normal endwise movement for effecting gear change, and the bolt member 65 is of suiiicient length that it will be disposed in a locking position with respect to the keeper E8 in any endwise position of the rod It. During the normal operation of the vehicle. the hand locking a gear shifting rod disposed parallel with a steering column, said locking means compris ing a keeper, means securing said keeper on said rod, a locking bolt, means adapted to be ñxed relative to said column supporting said bolt for movement relative to said keeper, spring means constantly urging said bolt to released po sition, and means connecting said bolt with said hand brake whereby said bolt will be moved to locking position when said hand brake is moved to brake lever 2i will be disposed in released posi tion which is the position shown in Figure l. In the released position of the brake lever 2l, the bolt member 45 will be held in its uppermost re leased 1:losition by the springs 52. When the brake lever 2i is rocked to braking position, clamping member 55 will be moved to the left as viewed in Figure l, and endwise movement of member 55 will also eifect endwise movement of bolt oper ating member 5.3 in the same direction. As bolt operating member E53 is moved to the left, rock lever B3 will be rocked upwardly at its outer end and the opposite end of lever 63 will be rocked braking position. 4. A device as set forth in claim 3 wherein said nr' ..40 latter mentioned means includes a spring whereby said locking bolt will be placed under tension when in locking position. 5. In combination, a movable hand brake op erator for a vehicle, a steering column, a gear shifting rod disposed parallel with said column, a downwardly thereby pulling bolt member 46 down 30 keeper fixed to said rod, a locking bolt for en gagement with said keeper for holding said rod wardly to locking position. The spring 65 will provide a tensioning means for tensioning the bolt 45 in its locked position. Assuming that gear shifting rod I9 is in neu tral position. keeper 68 will be positioned with the arms 13 thereof confronting the bolt member 46 so that when lever 2| is pulled to a braking position, bolt member 46 will he moved down wardlv between keeper arms 73. It will be ob vious therefore that when the driver of the ve against rotation, means fixed relative to said col umn movably supporting said bolt, and means connecting said bolt with said hand brake operator for effecting movement of said bolt to locking position when said hand brake operator is moved to braking position. y 6. In a vehicle having a steering column, a gear shifting rod parallel with said column, and a movable hand brake operator, a lock bolt, means supporting said bolt from said column, a keeper fixed t0 said rod in a position for engagement hicle attempts to effect a Igear change without re leasing the hand brake. the gear change cannot be effected as rod I9 is held against rocking move ment by means of the locked position of bolt member Q6. When hand brake lever `i?! is moved forwardly to released position. springs 52 will pull bolt member ¿i5 upwardly and forwardly to keeper Vwith said bolt when the latter is moved to locking position, and means connected to said bolt and said hand brake operator for moving said bolt to locking position when said hand brake operator is moved to braking position. 7. In a Vehicle as Set forth in claim 6 including a resilient element interposed in said latter means whereby said bolt will be resiliently held in locked disengaging position, thereafter gear shifting rod I9 may be rocked to any selected position. In the event the gear shifting rod I9 is in a position 50 position. Where the gears of the transmission are engaged, 8. A locking attachment for locking the gear the keeper 68 will be disposed in either of the shift rod mounted parallel with the steering col positions shown in Figures '7 and 8. In these en umn of a vehicle when the hand brake operator gaging positions of the rod i9. the keeper S8 will be disposed laterally of the bolt member l-i'â. In 55 is in braking position, comprising a housing adapted to be ñXed on the steering column and effecting change of gears from the engaged posi loosely engage about said rod, a locking bolt slid tion. it is necessary to rock the rod le in the op posit@ direction and this opposite rocking of rod I9 is prevented by reason of bolt member ¿S6 being in locking position across the path of the swing 60 ing movement of keeper 58. This device may be made as an attachment for a motor vehicle so that it can be mounted on the present parts of the vehicle or may be secured to the vehicle at the time of its original construc tion. What is claimed is: ably carried by said housing and projecting lat erally therefrom, a keeper adapted to be fixed to said rod in a position for engagement with said bolt when the latter is in locking position, and a ñexible member connecting said hand brake oper ator with said bolt for moving the latter to lock ing position when said hand brake operator is in braking position. 65 9. A locking attachment as set forth in claim 8 including a rock lever carried by said housing and connected to said bolt and said flexible member. 1. In combination, a movable hand brake oper 10. A locking attachment as set forth in claim 8 ator a steering column, a rockable and endwise including a rock lever carried by said housing and movable gear shift operator parallel to said col umn, a keeper iixed to said gear shift operator, a 70 connected at one end thereof to said bolt and a resilient connection between the opposite end of locking member supported on said column for said lever and said ñexible member. holding said gear shift operator against rotary movement, means constantly urging said locking WILLIAM H.`MULLINS.
