In this form of my invention, the body poreither direction from. its normal position.

and is centrally. located by a pair of-opposed springs SZand the fornicrof which corresponds to the spring 17 in the previous embodiment. The spring 32 is conlined be tween the upper surface of the body portion 4 of the lock and afiange 3 which. is carried by the head of the bolt or :rod and the spring 33 is interposed between the bottom surface of thebody portion 4 and a collar 31' which is carried by the rod '7. Below this collar, the bolt or rod is reduced in size and extends to withina shortdistanceof the sector or. gate 2 and has secured to its lower end a slide '37. by means of a projectio'n'38, which is'ot general U shape and which embraces the. edge of the lever l. The

slide is movably attached totlie side of the lever 1 by a rivet 39 which passes through the lever and through a bushing it) which is confined bet-ween the headwof the rivet-and the surface of the lever 1. The

. outer end of the bushing overhangs the edge of a slot 41 in the slide 37 and forms a spacer for the rivet 39't0 prevent its binding the slideS'T against the lever. This forms a cheap antlfcouvcnientmethod of attaching the slide to the lever, and insures freedom of movement. ll hen the parts are in normal position, or that shown in Fig. 7, the lever 1 is free tomove into any branch of the Hshaped slot. 3 within the sector or gate 2 except the one which represents the re verse for the automobile and which I have designated 3" in Fig. 8, the entrance of the lever into this portion of the slot being ordinarily prevented by the engagement of the lower portion of the slide 37 with the projection 2* oirthe sector or gate. :lhen it is desired to reversethe automobile, the slide 37 is elevated above the projection '2 by pulling upwardly on the rod .7, when the slide may pass over the top of said PIOJQC- tion. To expedite this operation 1 make the head of the rod 7 in the form of a ring into which the operator may'insert his finger. .-\'i'te r the initial movement of the lever in reverse (liiecti ii. the parts may bereleascd. allowing the slide EST-to resume its normal position, the slide being auton'iatically elevated when returning to central position by its engagement with the rear. inclined side Of-rthfi pro ection 2".

lock the leveagainst any movement other than a slight lateral shifting, the rod 7 is depressed as in theformer case to project the lower end of the slide 3'? into the slot 3, in which positionthe parts are held by the cooperation of'tlie Yale lock and the notch within the rod 7*.

F 10 and 11 illustrate a form of my inventionwhei'ein the the principal members of my lock, while the body portion 4:2, which contains the Yale 10, the body portion 432 is of general U shape in plan and embraces the forward edge of the lever 1, and it is secured to said lever by a 'rivet'lti which passes through a slot in one side of the U-shaped bodv portion 42 and through a hole in the. lever.

Between the head of the rivet l3 and the ad-.

jacent side of the lever l, the bo'dv portion 42 is enlarged to form a vertically disposed boss which is made hollow for the reception of a compression spring it that is adapted to hear agi-iinst the upper wall of the hollow boss and the rivet 43. This spring tends to elevate the body portion 4.2 and withdraw its enlarged lower end 45 from the Slot in the gate or sector To assist. the rivet 43 in accurately guiding the body portion 42, I provide a pin 4:6 which extends through the lever 1*- and projects ateither end into vertical grooves onthe inner walls of the legs of the Ushaped body portion 42. A

er 1 forms one of.

As will be seen from Fig. l

operates with the barrel of tl'ielock to retain the parts in locked position when the body portion 12 is depressed, in-tlie same manner as the. notches in the 'rods' 7 and 7 The notch 15, to which reference has been made hercinbefore, permits of the removal of the key after the barrel 8 has been turned to the position shown in Fig. 3.
