This improved lock is VYfor holding the door I of an automobile. 2 closed,-7andhas a casing4 3 Y mounted'within thedoor as shownin Figs. l and v2. A sleeve'dprojectsoutwardly from the face plate or wall 5 of the casing 3 and tsiinto anV opening 6 formed in the Woodside barfl atY the free side of the door. A shaft 8 extendsvlongi tudinally through the casing 3 with its inner and keeper showing the face I 2 is secured on the rear endV portion of the shaft the pocket is of reduced width to form a neck 42 in which one end of the handle is pivotally mounted by a pin 43 and the-portion of the handle which is received in the main portion of the pocket is formed with arms 44 and 45 defining. a recess 45 which permits .the handle to be by a set screw I3 and this collar or disc is engaged by the rearend of a helical spring I4 which urges the shaft inwardly and holds the head in contacting engagement with the outer edge face of the casing and retains the-arm II 'in the recess I5 of the free edge face of the door I. The spring also holds the rear endrof the-enlarged portion 9 of the shaft in abutting' engagement with the front end of a sleeve I6 which fits loosely about the shaft and is provided at its front end with a ilnger or lug I1 for engaging a. companion lug I8 easily grasped when 'the fingers of a hand are thrust into the pocket. A bracket 41, which is riveted against the pocket has an arm 43 projecting from the pocket and secured against thethe handle is pivoted the outer end of a link 5| which extends longitudinally through a sleeve projecting radially of the shaft from the rear end f of the enlarged portion thereof. Ears I9 project from the sleeve midway the length thereof, and,

between these ears, an eye bolt is pivotally mounted by a threaded pin 2|. A y The shaft and its arm "constitute means` for permitting movement of a latching roller 22 out of engagement with a keeperjduring opening of the door. `'l'his roller is rotatably carried by a' shaft or axle 23 projecting from the free side edge face of the door and the portion 24of this axle extends over the armso that when the door 'is closed, the roller may-enter the casing 25 of the keeper through registering slots 26 and 21 formed in they casing and in the face plate 28 of the casing Vand engage between` the stationary jaw` 29 and the movable jaw 301 of the keeper.

, Thermovable jaw of the keeper is providedvatitsouter end with a depending heel 3| through y which a pin 32 passes to pivotally mount the jaw and adjacent its inner free end this jaw is formed witharecess 33 to receive the roller 22 when the door is closed. A spring 34 normally holds the 'movable jaw in its lraised or gripping position and, in order tov cushion movement of the jaw 'Y to closed or gripping position, there hasbeen provided a rubber. cushion 34. A stub axle or stem V"3!5 projects lfrom the depending portion 35 of ,the

movable jawand carries a roller for engaging under the arm II of the shaft k8, and, from an inspection oflfig'. 5, it will be seen that when the shaft is turned in a direction to swing the arm downwardly, pressure will be applied to the roller31 to force the movable jaw downwardly to releasing position and permit the roller 22 to `move outwardly of the keeper during openingof thedoonpWhen the door is closed, the roller 22 again-enters the keeper casing and exerts a camfaction. on. the` sloping upper edge 38 of the movable fjawto depress this jawand allow the roller to move finto the recess 331. At this time,

the-spring {i4-shifts the movable jaw upwardly andthe roller will be gripped between the two jaws andthe door rmly held closed.

To open thedoor, the movable jaw must be depressedgto a position in-which the roller 22 the doorY through an opening formed transversely ofthe outershell 4|A of the door. A portion of 52 and has its inner end pivoted to an ear 53 v extending outwardly from a block `or coupling 54 slidably mounted in the sleeve 4 and formed with a threaded socket to receive the eye bolt 2|I. When the handle is grasped and pulled outward- 1y, pull is exerted on the link and the block 'and also upon the eye bolt and the sleeve I5 is turned to move the lug I1 into engagement'with the lug I8 and thus turn the shaft 8 in the proper direction to swing the arm I I downwardopening the door may then enter the automobile. When the handle A38 is released, the spring 55, which is coiled about the link 5| and the'ear 53l of the block with its ends abutting the block and the neck 42 of the socket, expands and forces the block inwardly so that the sleeve is turned about the shaft and the shaft may be turned by engagement of the arm II with the roller 31 and restored `to its initial position during the closing of theA door and movement of the roller 22 into the keeper, where it is gripped between the two jaws of the keeper to hold' the door closed.

When the door is closed by a person standing outside the automobile, and it is desiredto secure 'end a bill or arm-'51 which projects radially of the lock and is of sufficient length to pass through the slot 58 formed'in the adjacent end of the rpocket 4I| and enter the notch 59 vof the free end y of the handle. As long as vthe bill is engaged in the notch v5i), it will be impossible to open the It is also desired to permit the door to be sel cured closed by a person within the automobile. To accomplish this, there has been provided a latch consisting of a knob 50 having a shank 3| which is rotatablymounted through the wall of the casing 3 and through an inner face plate 52 which may be a portion of the inner shell of the door. v'I'he shank of the latch carries an arm or bill 63 at its inner end which projects radially l @317,700 been provided a rod '65 which extends' trans-- .The rod 65 extends to a point adjacent the hinged side of the door and is rotatably mounted transversely throughs, chamber 68 which may be an extension of the pocket 69 of an vinner face plate 10 or be formed separate from the pocket 69. A lug 1| is carried by lthe portion of the rod within the housing 6 8 for engagement by a lug 12 projecting from an end of a sleeve 13 tting loosely about the rod, and, from an inspection of Figs. 9 and 10, it will be seen, that the sleeve is formed integral with a shank or arm 14 .projecting from the lower end of Va handle 15. A lip or heel 16, at thelower end of the handle 15 prevents tilting of the handle outwardly beyond an upright position and, when the lever is pressed upon and forcedv into the pocket 69, the lug 12- will be brought into en' gagement wtih the lug 1| and turning motion impared to rod 65 to rotate the shaft `8 in a' releasing direction. It will thus be seen that the door may be released by a person within the engagement with'the door-carried member when the shaft is turned 'in a. releasing direction, and

automobile aswell as by a person outside the automobile. It-will also be seen that since lthe sleeves I6 and 13 are loosely mounted about the shaft and rod, the door may be released for opening by either of `the handles without the other handle being swung out of its normal position.
