GEORGE HALINKA, OF DETROIT, MICHIGAN.

LOCK.

To all whom t may concern.'

Be it known that I, GEORGE HAIIINKA, a citizen of the United States of America, re' siding at Detroit, inthe county of Wayne and State of Michigan, have inventedcertain new and usefulA Improvementsin Locks, of which the following is a specication, reference being had therein tothe accompanying drawings. This invention relates to locks, and the object of my invention is to provide 'a lock embodying a latch hama-handle for moving the latch bar to a l,retracted position, and a permutation mechanism adapted to prevent the retraction of the latch bar, unless the permutation mechanism` is properly set. The lock may be used in various places, but more particularly on the door of an automobile or other vehicle, since the handle of the lock is countersunk in the lock casing and does not present a protuberance relative to the door. The handle is shaped that it may be easily gripped by the lingers' toA actuate the latch bar of the lock, land all the mechanism is compactly assembled and may be easily maintained in an operatable condition.

My invention will be hereinafter specifically described and then claimed, and reference lwill now be had to the drawings,

Figure 1 is a longitudinalsectional view of the lock; and

Fig. 2 is a front elevation of the same.

In the drawing, the reference numeral 1 denotes, by the way of an example, a portion of a door that is recessed, as at '2, to'provide clearance for the lock, whichcomprises an angle plate 3 adapted to be connected to the door 1 by. screw bolts 4 or other fastening means. A

Supported at one end of the angle plate 3 is a conventional form of .permutation mecha- `plate 3. i t

nism 5 includingvrotatable disks -6 disposed in parallelism andA provided with notches 7.

At the opposite end .of the plate 3 is a latch bar Shaving a head 9, a yoke 10, and a latch 11'. The latch bar 8 is slidable in bearings 12, carried 'by a handle casing 13 4 supported by and inset relative to the 'angle In the handle casing 13 is' stirrup shaped Specification of Letters Patent.

said casing providing clearance for'the ngers so that the finger piece 15 may bei 55 gripped to' swing the handle out of the casing 13. f-

, One end of the handle 14 has a lug 16 extending into the recess 2 of the door 1, and also into the yoke 10 of the latch bar 8, said lug belng pivotally held on a pin 17 mounted 1n apertured lugs 18 carried by the' angle plate 3. Itis therefore possible to swing the handle 14 outwardly, from the handle casing 13 and cause the lug 16 to' retract the latch bar 8. `To hold'the latch bar in an extended position, a coiled compression spring 19 encircles said bar between the yoke 10 and one of the bearings 12.

When the disks -6 of 'the permutation mechanism' are properly adjusted 'to place the notches 7 in alinement, then the head 9 of the latch bar 8 may enter said notches, when the latch bar is retracted by swinging the handle 14 out of the casing 13. When the notches 7 of the disks '6 do not aline, then the head 9 of the latch bar 8 will impinge against the peripheries of the disks 6 and I prevent the retraction o f the vlatch bar 8 thereof at said permutation mechanism and the movement of said bar controlled in a radial direction thereby, a yoke at the opposite end of said barge, stirrup shaped handle pivotally supported by said angle plate with said handle normally in said handle casing and adapted to be swung outwardly away from said permutation mechanism, and a lug carried by the pivoted end of said handle engaging in the yoke of said latch bar and adapted to shift said bartoward l said permutation mechanism.

In testimony whereof I affix my signature m0 in the presence of two witnesses.'
