Application March 22, 1935,. Serial No. 12,358 1 Claim. (01. 292-158) This invention relates to door lock mechanisms of particular adaptability to vehicles wherein the requirements of construction are limited by. the width and thickness dimensions of the door post and the presence of sliding windows.

The trend in automotive construction is toward smaller door pillars. The space heretofore available for the lock mechanism is not only restricted in size hut must now accommodate the window pane in such manner that the pane extends into the path of the mechanism, it is therefore on objector this invention to provide a lock mechanism which will interfit with and actually straddle is a horizontal section taken along the F lines 22 oi Figure l;

2i vis a view taken along the line 3-4 of Figure 2;

Fig. i is a plan view of the interior handle partially broken away to show the hinge thereof;

Fig. 5 is a section along the line d--li or Fi ure 1;

d is a sectiontaken along the line 6-t of Fig. i;

Fig. l is a detail section similar to Figure 2 showing the lock cylinder in looking position;

Fig. 8' is a plan view of a modified form of exterior handle, and

Fig. 9 is a section taken along the line 9-8 of Figure t.

t and i2 refer to the interior and exterior walls respectively of a door. having a lock and latch mechanism therebetween for engagement with a keeper member 3 carried by a door post t. A handle h is pivotally mounted at 6 in a casting l secured to the inner well i in such way that when the handle is in door latching position the outer surface of the handle is substantially flush with the wall l. Integral with the handle 5 is a bent arm t the end of which has sliding en- 9 8 opposes. retraction of the bolt ll and returns it to latching position upon release of either handle 5 or M.

The handle ill is also preferably embedded in the door so that the outer surface thereof is substantially flush with the wall 2.

A look if! is carried by the handle it near its outer end. The cylinder of the lock extends inwardly of the casting l3 and has an extension it adapted for rotation to a. position directly abutting the end of the bolt in to oppose retraction thereoil The extension II also acts to directly oppose withdrawal of the handle M and loch it from the casting 42 as best seen in Fig. l.

Pivotally mounted within the door is a bell crank 22 having one end adapted for rotation to a point directly opposing withdrawal or the bolt it. The bell crank 22 is actuated by a push rod 23 frame point within the'contour of the handle fl 4 it will be seen that the pane of glass 24 iuter-= fits with the locking mechanism and that the handles 5 and i l reside adjacent opposite surfaces thereof.

The modification shown in Figures 8 and 9 is similar to that previously described with the exception of the handle a. In this form. the handle Ma has a rounded outward surface so that its edges all merge into the contour of the body. This handle preferably resides horizontally so that the palm of the hand is upward when gripping it for pivotal opening.

What I claim is:- Y

A door lock mechanism for a hollow vehicle I door having a window pane slidable therein with the edge of said pane extending into close prox imity to an edge of said door, said mechanism.

comprising a bracket mounted on a wall of said.

all

actuating said latch bolt, a bracket mounted on the opposite well of said door and on the opposite side of said pane, the second bracket being adapted to support a handle for actuating said latch bolt, said latch bolt having a projecting element thereupon, a bell crank pivotally mounted in the space between the edge of said pane and said edge of said door, said bell crank. being adapted to he moved to a position where one end thereof engages said projecting element and directly opposes movement of said latch bolt,

and a. push rod mounted on the second named bracket and-connected to the other endof said bell crank for moving the same.
