In the drawings', see Figs. 1, 2 and '1, the door 40 is shown in its closed position, with the lock bolt 88 having its face 90 bearing against the vertical face 33 of the locking seat of the keeper 28. In this position the outer ,face of themember 46 of the `housing 45 abutsagainst the stop' 39, and the door'40 is securely locked in its :closedv The e bolt. The balls 96 andSB at this-closed position Vof the door are respectively located intheir cam cavities 14 and 84 as indicated insaidFig. 8.,l

If the lock is to be opened from,l` the outside,

the operator before `leavingtl'ie vehiclepushes,

down the inside adjusting handle |66, to disengage the locking lug |6I from the latch cavity |49 of the arm |46 of the bell crank |44 and thereby the latch heel |41 is disengaged from the latch |09 of the operating lever |00. This dis'- engagement results by the end |52 of the spring |50 bearing on the arm |45 of the bell crank |44. The operator then by means of the outside operating handle ||4 swings down thel operating lever in the direction of the arrow B, which swings the bolt 88 in the direction of the arrow C, Fig. l and the locking nose 9| is disengaged from the keeper 28 and the door 40 can be swung open.

If the operator wishes to remain in the vehicle and be protected from any one opening the door from the outside, he pulls up the inside adjusting handle |60, to lock the arm |46 to the operating lever |00.

To open the lock with the inside operating handle |80, the latter is swung down, to move the connecting rod 202 in the direction of the arrow M, Fig. 1, and the arm |1| of the bell crank |10 bears on the nose 93 .of the bolt 88, to swing the latter in the direction of the arrow C, and the said bolt 88 is swung in position to open the door 40.

Referring to Fig. to swing the bolt 2|0 to open the lock with the outside operating handle, the operator moves the connecting rod 2.46 'in the direction of the arrow O, to the position indicated in said Fig. 10 to engage said rod with the pin 234 to disengage the locking lever 23| from the lever 225. In this position of the lever 23| the outside operating handle ||4 with its square shank 220 can be` turned to open the lock. When the handle ||4 is turned in the direction of the arrow N, the hook end 256 of the lever 255 coacts with the nose 2|1 of the bolt 2|0 and thereby the nose 2|3 of the said bolt 2|0 is disengaged from the keeper 28. Upon the release of the outside,operating handle ||4 the end 244 of the spring 240 swings the lock bolt 2|0 to its locked position. To prevent the opening of the lock with the outside operating handle H4, the connecting rod 246 is moved in the direction opposite to the arrow O, to position the outer end of the elongated opening 249 against the pin 221, whereby the pin 234 is disengaged from the bottom edge of the connecting rod 246, and the latch end 233 of the lever 23| is locked with thel notch 226 of the lever 225.

To open the lock with the inside handle |80 in this modification, the connecting rod 246 is moved in the direction of the arrow O, and the lever 23| is disengaged from the lever 225,` and the hook lever 255 coacting with the nose 2|1 swings the bolt 2|0 to enable the door 40 to be opened.

When the bolt 2|0 swings up, its lug 2|5 engages the lug 250 of the connecting rod 246 to disengage the lever. 23|.'from the lever225 and theoutside handle ||'4 can be operated.

- When the door 401s swung to its closed position, the bolt. 2|0 approaches thefkeeper 88, the bottomy 2|4 of the locking nose 2|3 slides up on theupper inclinednfacerof the keeper 28 and is ultimately seated .in the seat of said keeper havingthe lfaces 33 and 34,. Y,

vBy the coaction of the balls 96 with the cam cavities 14, the said balls 96 move from the crowns 11 to thepeaks 11a, by virtue of which the outer face of the member 46 of the housing 45 o the lock is positionedto bear against the stop39.

If, the door 40 is in its closed position and Yis swungopen with the inside operating handle |80, the balls 96 and 98 will be positioned with respect to their cam cavities as shown in Fig. 9.

It will be noted,l see Fig. 1, when the operator opens the door 40 by means of the inside operating handle |80 and forgets to manually lower the inside adjusting handle |60, to unlock the operating lever |00, in such a case when the lock bolt 88 is swung to its open position the adjusting nose 93a bears on the heel |62 and lowers the adjusting handle |60 to disengage the lug |6| from the latch cavity |49 of the arm |46 of the bell crank |44.
