PatentedJune 14, 1932 res UNITED STA WILLIAM J. SEELINGER, OF DETROIT, MICHIGAN comma]: AUTO DOOBLIOCK AND DOVETAIL Application filed April 16,

This invention relates to automobile door latches and the like where it is very essential to both wedge the door tightly when in its closed position to relieve strain on the. hinges,

and to avoid relative movements resulting in rattiing and other noises, and which must be very securely latched in closed position.

The essential object of the invention, is to provide a very simple effective combined wedgingand latching means for such dooda which may be cheaply manufactured, easily,

installed, and which may be operated in precisely the usual manner, namely, the latch may be operated by a door handle outside the 1!, door and a handle inside the door, which for convenience is usually placed at a position remote from the lock itself, that is to say, from the shank of the outside door handle.

A more specific object is to arrange a combined wedging and locking means such that the wedging efiect may be resilient and not subject to wear and yet exert very great resistance to any tendency of vertical movement'between the door and door jamb.

Another object is to so construct'and arrange the parts as to be capable of a very great amount of wear and of easy and convenient replacement.

A further object is to construct the parts of this combined dovetail and latch-means sdthatthey may be assembled with the least possible change or alteration of the usual and standard forms of doors and door jambs used in automobile body onstruction.

The above and 'ot er objects will become apparent in the following description which refers to the accompanying drawings, the essential characteristics being summarized in the appended claims.

In the drawings-- M .Fig. 1 is a perspective view of the door showing the latching and handle operating elements-in position. 1 c

Fig. 2 is a transverse horizontal section through the latch and operating means when dis osed in latching position. v

ig. 3 is a sectional view of the door ortion of the latching means, taken on a p ane indicated by the hne 33- of Fig. 2.

1931. Serial 110. 530,487.

Fig. 4 is a vertical sectional View through the wedging and latch receiving means on the door jamb or frame.

Fig. 5 is a vertical sectional view showing the operation of latch by the inside or remote control mcans, a d is taken in a plane indicated by the line 44 of Fig. 2.

Referring to the drawings by the use of numerals designating like parts in the various views, 10 indicates the usual door and 12 the door frame. The door has a suitable vertical door post or frame member14 having a wedge or sloping front face as is customary and which is cut away to receive the latch housing member 15. The latch housing member 05 comprises a' plate member, shown as secured by screws 16 to the post 14, and having a raised middle portion whiclf forms a hollow wedge shaped .element 17. The upper and lower walls of this wedge shaped element are preferably formed on the same plate but may -be formed from a separate plate, while an inner plate on the door forms the backing portion of this combined housing and wedge element.

Through the lower wall of the wedge portion 17 I provide an opening 18 through which projects the latch dog 19 of the latch bolt 20. This so-called latch bolt is shown in the form of a pivoted dog/the pivot 21 comprising a suitable pin passing through the front and rear walls of the housing formed by the wedge portion 17. The forward portion of the pivoted dog is prefer-- ably provided with a surface or shoulder against which acts one arm 22 of a latch actuator 23 non-rotatably secured to the shank 24 of the usual handle 25. A spr ng 27 suitably positioned by a, depression iii the top of the latch bolt 20 is provided, the other end of 99 the spring being positioned either by depression or projection inthe wedge member 17, as indicated at 28. Thus, the spring, which is practically a compression spring, 9 acts to press the latch dog downwardly but 7 permits it to rise yieldably during the latching operation, as will later appear. It is to be" understood that the spring action forcing '1 the latch bolt downwardly may beeffected 10o by the use of a fiat spring or springs of any suitable character.

On the door frame 12 I prefer to mount a suitable pair of housings 30, which may be rigidly secured or formed on a suitable plate 31 held by screws or otherwise. The coacting wedge elements preferably comprise metal blocks 33 slidably held in the housings and positioned by overhanging shoulders formed on the housing and on the blocks, as indicated at 34 and 35' respectively. For pressing the blocks 33 relatively toward each other, I employ any suitable resilient means, preferably solid blocks of rubber, indicated at 38, which are held in position in the housings under comparatively heavy compression urging the blocks relatively together.

enerally, are sloped to correspond to the slope of the Wedge shaped housing 17 and they are normally positioned to tightly grip this housing as the door is brought to the closed position. The latching position is indicated in broken lines in Fig. 4, in which position the latch 19 is in engagement with the innermost shoulder 37 on the lower block 33. For a double,

latching effect, I may provide the additional notch, as at 41, and for convenience in manufacture I may make both the blocks 33 alike, whereby they may be entirely interchangeable, although obviously the upper latch normally functions only as a coacting movable wedge gripping element.

It will be seen that to open the door with the latch, it is only necessary to lift the latch bolt 20 with its projection 19 by moving the arm 22 upwardly upon the turning of the shank 24 or carrier of the arm.

As stated, the opening may be accomplished by'the usual remote or inside handle. This may be of the usual or any suitable construction, the handle being indicated at and shown as passing through the inner panel of the door to a crank or link element 51 secured to a link 52, which in turn is pivotally connected, as at 53, with a second arm 54 of the element 23. Actuation of the handle to move the link 52 longitudinally may effect the raising and lowering of the arm 22. Consequently proper actuation of the handle 50 in one direction may cause the raising of the latch bolt, thereupon unlatching of the door.

Key locking arrangements of, any suitable description may be applied to the lock through the hande bolt element or otherwise, as is customary in such devices, it being only necessary to prevent the rotation of the bolt to provide an effective locking of this latch.

From the foregoing description it will be seen that I have prov ded a latch cap-able of being attached to automobile doors or like doors, and which when the door is closed combines a wedging action which replaces the the inner faces of the blocks 33 usual so-called dovetail support commonly used between the doorand door casing for preventing relative vertical movement between these parts. I have also secured a very powerful and yet resilient gripping action between the elements on the door casing andthe elements on the door, and yet a gripping action which is consistent with the easy opening and closing of the door. It wlll be seen that the/resilient elements have little or no wear and yet these, with the wedge elements 33, may be readily manufactured and easily replaced.

The standardized door handles and shanks and inside handles and so-called remote control for latches need only a minimum amount of change or substitution for use with my door latching devices.

It is to be understood that various modifications and alterations may be made within the scope of my invention and without departing from the spirit thereof.

I claim:
