I AUTOMOBILE DOOR LOCK Filed Aug. 12, 1959 5 Sheets-Shet s jj af 4/ Patented Oct. 13, 1942 v UNITED I STATES PATENT OFFICE AUTOMOBILE noon LOCK Henry M. Fredholm, Midlothian, 111. Application August 12, 1939, Serial No. 289,743 7 Claims. (01. 292-) This invention relates to automobile door locks and particularly to means for preventing unauthorized manipulation of the lock.
Automobile doors heretofore have been provided'with locking bolts actuated by handles on the inside and outside of the door, such bolts being retracted by pressing downwardly on either handle. By raising the handle on the inside of the inside of the door when closed, the handle on the outer side of the door is rendered immovable and the locking bolt is held in locking position. It has been found, however, that unauthorized persons have been able to open such locked doors by inserting a wire or other device through a small crack between a window and frame and pressing downwardly on the handle on the inside of the door. I
The object of my invention is to prevent such unauthorized manipulation of the lock and to provide locking means for retaining the handle onthe inside of the door in bolt locking position, which means require an operator to exert pressure on said means in directions at right angles to each other in order to actuate said lockin means to release the bolt. The construction is such that it is impossible for a person outside of *pivotally mounted wing windows now used in automobile doors. Most unauthorized manipulation of door locking means by persons outside of the car is accomplished by entry through the wing windows, and therefore the locking of said windows by the means herein described is an important feature.
In the drawings:
Fig. 1 is an elevational view of door locking means embodying my invention as viewed from the inside of the car, with the doorupholstery removed.
Fig. 2 is an elevational view, partly in section, of that part of the locking means of Fig. 1 which embodiesthe invention, taken in the plane of the line 2-2 of Fig. 4.

' and the plate I4.
Figs. 6 and Rare enlarged sectioi ial ...views In Fig. 1, a conventional automobile door I0 is provided with a locking bolt II, bolt housing I2, operating handle I3 mounted on the inner side of the door on a plate I4, and operative connections between the inner handle I3 and bolt II, including the links I5 and I6. These are conventional loci-r parts, in which downward pressure on the handle I3 retracts the bolt II, and raising of the handle I3 above the position shown in Fig. 1 prevents movement of the outer handle I3 (shown in dotted lines) on the outside of the door.
My invention comprises certain cooperating parts which are mounted between the handle I3 Said parts include a block I! bored at I8, having pivot extensions I9 and 20 at opposite sides. The hub 2| of the handle :3 is recessed to fit on the pivot extension 20 of the block I! and is secured to the part 20 by a. set screw 22. The hub 2| is provided with a recess 23 and the extension 20 is bored at 24 to receive a plunger 25 having a presser button 26 on its outer end, externally of the handle I3. The plunger is retained in the recess 23 by a collar 2'! bearing against the end wall of the recess 23.
A'lever 28 extends through thebore I8 in the block I! and is mounted on a pivot pin 29 fixed in the walls'of the block II. The end 30 of said lever is adapted to bear on a pin 3| mounted in a housing 32 fixedly secured at 33 to the part I9 of the block I1. The pin 3| has a flange 34 spring pressed by a coiled spring 35 normally to cause the pin to project from the housing32, as will be explained.
I The opposite end of the lever 28 is adapted to engage and disengage a. stop shoulder 36, 36', formed in the wall 31 of an angle plate 38 fixed to the plate I4 by screws 39.
When it is desired to lock the door ID, the door is closed and the handle I3 is raised from the position shown in Figs. 1, 2 and 4 to the position of Figs. 3 and 5. Raising of the handle i3 causes the block l1, lever 28 and housing 32 to move with the handle about the pivotal center of the handle hub 2| and the pivotal extension I! mounted in said plate l4. While the handle i3 is being raised, the lever 28 slides on the outer edgeof the flange 31 of the angle plate 38, as shown in Figs. 2 and 6, and when it has been raised to the limit of its movement, the lever 28 comes opposite the shoulder 36. and engages the shoulder as shown in Figs. 3 and'l. The shoulder is formed by cutting away part of the end of the flange 31 of the angle plate 38 on a diagonal line 36, and on the line 38, as best shown in Fig. 3. The lever 28 is held in shoulder engaging position by reason of the expansive tendency of the spring 35, causing the pin 3| to project and to bear against the end 38 of the lever 28, as shown in Fig. 5. Thus the handle I 3 is locked in its raised position by the engagement between the lever 28 and the fixed shouldered angle plate 31-38. 7
To release the handle I3 from locked position,
- it is necessary to press on the button 26, causing the plunger 25 to-move the lever 28 on its pivot 29, against the pressure of the spring pressed pin 3|, and while pressing inwardly on the button 26, to bear down on the handle i3 to move it downwardly about its pivotal connection to the door. It is necessary for the operator simultaneously to exert pressure in two directions, at right, angles to each other, a feat impossible to accomplish from outside of the closed door.
It will be understood that the parts located between the handle and the fixed plate |4 may be housed in a depression in the door I8 and con cealed by upholstery, not shown.
In Figs. 8 to 11, inclusive, the door locking means heretofore described has been applied to a door 40 having a window 4|, pivotally mounted at 42. The bolt I, housing 2, handle I 3, plate l4, and parts between the handle l3 and plate l4 are constructed as heretofore described, and the operative connections or links 43 and 44 correspond with the links l and I6, but the link 43 is disposed at a different angle and is connected to the handle I3 by a lever 45 pivotally connected at 46 to the link 43 and fixedly mounted at its other end on the square end 41 of the handle pivot. The handle |3 operates, as heretofore described, to actuate the bolt II, and the latching lever 28 and shouldered angle plate 31-38 serve to lock the handle, as described.
To prevent opening of the window 4| from the outside of the car, I provide as a part of the operative connection 43 levers 48, 49 and pivotally mounted bolt or lever 50, the latter engaging a keeper plate 5| fixedly mounted on the window 4| by screws 52.
The lever 48 .is 'rigidly connected by rivets 53 to the link 43. The levers 48 and 49 are pivotally connected at 54, and the levers 43 and 58 are pivotally connected at 55. The bolt or lever 50 is pivotally connected to the door 40 by aheaded v pin or screw 58.
When the handle |3 has been moved to raised position as heretofore explained, the bolt or lever 50 will engage the plate 5| and prevent opening of the window 4|.
Changes may be made in details or construction without departing from the scope of. my invention.
