application laca nay's, 1929. serial No. 361,530.'

This invention relates to locks and latches for automobile doors, and especially to that type in which the device can be used as a latch freely operableby a handle or whichcan be ,-yused as a lock requiring a key for its operation.

The objects of the invention are:

First, to provide a latch offering substantially no resistance to the latching of the Adoor in closing thus avoiding jarring the doorv arts. P- Second, to produce a tight anti-rattling holding of the door in latched position.

Third, to provide a dogging means effective within an appreciable angle of swing of the latch bolt.

Fourth, to rovide alatcll requiring a Very shallow mortlse in the edge of the door.

Fifth, to provide such a latch having means for clogging the outside operating means by manually operated means from -within the door, said -dogging means being 'operable from without the door by means of a key. lSixth, such other advantages as will appear from the construction and relation of the several parts comprising the cooperating elements of the latch and lock, as set forth by the following detailed description:

The inventionconsists of structural characteristics and relative arrangement of ele'- ments which will be hereinafter more fully described and particularly pointed out in the appended claims.

In the drawings, in which similar reference characters indicate similar parts in the sev`- eral figures: A I

Figurev 1 is an elevation of an automobile door with our lock in position thereon Figure 2 is a perspective view of a. door with the lock in place, as viewed from' the inner side and edge of the door;`

Figure 3 is a sectional view taken on lille 4III-III of Figure 1;

Figure 4 is an edge view of the lock in elevation with the face or` end plate removed;

Figure 5 is a vertical sectional View on a line taken just 4within the outer side plate shown in Figure 4;I Figure 6 is a horizontal sectionalwview taken on line `VI--fVI of Figure 5, looking in the direction of the arrows;

' Figure 7 is a horizontal'sectional View of the device showing the door partly open with 13 'of plate 12 formingthe'to plate of the casing and at its lowerend y the hollow post 16 through which one of the screw bolts extends.

The casing is mounted ina chamfer or mortise in the edge-of the door so as to lie flush with the inner surface of the door 10 and with its. edge as shown in Figures 2 and 3..

The lock casing being open at its edges, excepting the top edge, a separate covering plate 18 is fastened to the door to cover the open end of the lock. The lock casing has a plate 19 rigid therewith for fastening the lock casing tothe door by means of screws or other well known fastening means.

Between the top plate 13 and partition plate 14v is journalled the latch bolt 17mounted for swingino movement by means of a shaft 20 rigid with bolt 17. Shaft 20 has its lower end projecting through partition plate.

14 and split as at 21 to tightly receive the end of a torsion spring 22, `the other end of which is fastened as at 23to the casing wall. l

`Spring 22 normally swings bolt 17 into ythe door releasing or retracted position shown 1n Flgure 7.

.The swinging bolts 17 formed with twol -teeth or projections 24` 25, tooth 25 continuously projecting from the lock casing lnto the t path of a keeper lug 26, tooth 24 projet-.table into the path of said lug on they closing of the door so as toconfine the keeper lug 26 between teeth 25 and 24, as shown in Figure '3. The side of bolt 17 adjacent tooth 24 is arc shaped at 27 with the axis of shaft 20 as a center, While the side adjacent tooth 25 is shaped as an arc at 28 so as to allow a swinging of the bolt about 20 as a center without contacting with the sides of the lock casing.

partition pla-te 14 and is normally swun to At 29 the bolt is formed with a straight side joining the are `sha d sides27, 28,l as shown in Figure 3, an so arranged as to form an acute angle with the path of travel of a latch clogging or locking means 30 when bolt 17 has been swung into ther door looking position shown in said figure.

. Lever 30 extends through a slot 31 in the contact with the periphery of bolt 17 by a eaf spring 32 having one end inserted into a kerf in lever 3() and the other end contacting the end of slot 31, as shown. Lever 30 is pivoted on screw bolt 15 within post 16, said post being` slotted throughpart of its circumference as at 33 to allow swinging of lever 30 vthrough its arc of movement. 4

34 designates a squared handle spindle extending through the lock casing having an outer handle 35 and an inner handle 36 nonrotatably connected vthereto and journalled for rotation in apertures in

casing Walls

11, 12.

Clamped to spindle 34 by set screws 39, 40 for rotation therewith are two arms 37, 38,

said arms being normally held in contact with anv abutment in the form of one of the clam ing screw bolts 15, shown in Figures 4 an 5, by .a coil spring 41 fastened at one end about the neck of set screw 40, the other end Contactin the fixed screw bolt 415.

Arm38 swings in the pathof movement of leveri30 and on rotation Oeitherhandle is capable of moving lever 30 against'the pressure of spring 32 so as to move said lever out of contact with the periphery of bolt 17.

A sleeve 42 is clamped ybetween plates 11,

and plug 46 having its outer end slotted as at 48 for the' reception of a key. Plugs'45 and 46 are independentlv rotatable and are prevented from longitudinal movement by parts 49, 50 rigidly attached to the respective plngs,'as shown in Figure 6, but allowing limited rotary lmovement in slots 51, 5 2 in 'lhe part or (logging arm 49 swingsy in the path of movement ofarln37'on handle spindle 34, its 'end being formed spatulate so 'as to be capable of securely seating in a.

The keeper lug 26 may be provided by bending a strip of .metal upon itself, thus providing at the same-time attaching ears 56,
