Appumin september' 11,1935, seria1No.4o,osz A9 claims. (ci. 29e- 164) This invention relates to improvements in locks for doors and particularly to locks for securing the doors-of motor vehicles.

In my Patent No. 1,908,343, granted May 9,

1932, is disclosed a lock and latch which comprises essentially a wedging means adapted to be secured to a door and a'wedge receiving Ameans adapted to be secured to a door frame, the wedge or near the center` of the door. As is Well-known,

the operating handle of the remote control devices customarily employed for the operation of motor vehicle locks may be moved in either of two directions, movement in one direction effecting retraction of the latch bolt and thus releasing the door and movement in the other direction eiecting the locking of the latch bolt so that the lock may not be released or operated by anyone without the vehicle. Without additional means it is possible for the operator of a motor vehicle of the closed body type to so adjust the locks of the vehicle doors that, after the operator has moved to the outside of the vehicle and closed the doors thereof, he cannot thereafter open them, being eiectively locked out.

Hence it is customary for manufacturers of such vehicles to provide mechanism in addition to the ordinary latch and remote control mechanism for preventing the operator from locking himself out of the vehicle by a certain procedure in manipulating the remote control handles, which in turn operates the inside locking device; for example, if the operator of a four door sedan body, after completely locking the car from the inside, chooses to exit from the left front door, and after leaving the vehicle and While the door is still openlocls the door by reversing the remote control handles and then slams the door" tains the outside lock, and lock the vehicle with the key. It is customary in this country to provideK the outside key lock on the right side of the vehicle next to the curb when parking, and the steering wheel on the left side of the vehicle, while in certain countries this practice is reversed,- therefore necessitating the rev'ersal of the procedure of Ilocking.

The present invention contemplates the addition to and combination with the novel form of lock and latch disclosed in myprior patent of a mechanism of the type just referred to. That is, a mechanism which makes it impossible for a vehicle operator to lock the door to which -the vmechanism is applied by operating the inside locking device save with the door in completely closed position. The invention contemplates the `combination with the wedging means which is to be applied to a door of a device which cooperates with the moving parts of the lock in such manner as to insure that these parts may not be set by the operator prior to his leaving the vehicle in such manner as to automatically lock him out when the door is closed after his exit therefrom.

Numerous ways of eiecting the desired objects may be devised and in the accompanying drawings several mechanisms of this character are `illustrated by Way of example.'

Numerous parts of the lock supporting frame and certain of its operating members may be of conventional form and need not be described in great detail. A complete locking unit, however, will comprise a wedging means and its associated parts, such as illustrated in the first ten figures of the drawings, which means is adapted to be mounted upon adoor, and the `wedge receiving means illustrated in Figures. 12 and 13, which is adapted to be mounted upon the ,door frame. 'Conceivably, in certain instances the wedge receiving meansv may be. `mounted upon the door andthe wedging means Vupon the door frame, as will be understood. but preferably the wedging means', which includes the latch bolt, will be mounted upon the door and the wedge receiving means upon the door frame.

Referring now to the preferred form of the invention shown in Figures 1 to 13 inclusive. The wedging means previously referred to comprises essentially a supporting arm or lug II) which' is adapted to project beyond the free edge of the door for a comparatively short distance as shown in Figure 1 in which the approximate position of the free edge of the door is indicated by the chain line a-a. The flat upper surfac`e of arm I is preferably substantially horizontal in the case of vehicle doors or at any rate is disposed substantially normally to the axis about which the door swings inl its opening and closing movements. In cross-section, member I0 is itself slightly wedge shaped, as shown in Figures and 6 with its thinner .edge rounded as shown. The wedging means includes not only themember I0 but also the latch bolt II, this bolt having a flat lower surface which slidably rests upon and is supported by, the nat upper surface of the supporting arm I0. The latch bolt portion II of the wedging means is likewise itself wedge shaped in cross-section, its thinner or leading edge being rounded as shown. Intermediate its edges the latch bolt is provided on its upper surface with a tooth I2, which tooth will perform latching functions when the door is only partially closed.

The wedge receiving means includes a suitable casing orhousing member I3, the details of which may vary within wide limits, and which is adapted to be firmly secured to a door frame member and to serve as a housing and support for the operating parts of the wedge receiving means. This wedge receiving means includes spaced metallic wedge contacting members I4 and I5 and backing and supporting blocks I6 and I1 of rubber, these blocks serving to resiliently support, against separation, the jaws I4 and I5. The upper surface of the lower metallic jaw member I5 is inclined as shown in Figure 5 and is a smooth surface in order that it may have full contact with the inclined lower surface of supporting arm I0 when the door is closed, as indicated in this figure. The lower surface of the upper jaw I4 of the wedging means is toothed orl serrated, the intermediate tooth I8 thereof being adapted to drop down behind tooth I2 of the wedging means when the door I is completely closed and the enlarged tooth I9 Figure 5 vduring the flnal closing movement of the door, the rubber blocks i6 and II respectively being compressed as the upper and lower jaws I4 and I5 are parted to receive the wedging means and thereafter expanded to maintain the jaws I4 and I5 in tight engagement with the wedging means. Any portion of the weight of the door which may not be carriedby the hinges, due to looseness and wear, will be transmitted to the jaw I5 and thence through the rubber block I'I to the door frame so that it is apparent that at all times while the door is shut it is resiliently supported at its free edge by the wedge receiving means, thus taking a portion of the weight. of the door off the hinges if the wedge receiving means is properly positioned, vand preventing rattling due to vertical movementsv of the door or to vibrations of the vehicle to which it isr attached, the upper expansible rubber block I6 pressing the upper jaw I4 downwardly at all times into close engagement with theupper surface of the latch bolt. In the event that the door is only partially closed, the shoulder I2 vof the latch bolt will engage in behind the tooth I9 of the upper jaw I4 and the door will be retained in this position, effectively locked against outward swinging, until the. operator has opportunity to effect the complete closure thereof.

To permit opening the door, the latch bolt portion II of the wedging means is axially'retracted, causing its upper surface to disengage the lower surface of the-upper jaw I4 of the wedge receiving means and thereafter the door may be freely swung open. 'I'he various parts thus far described are, in essence, described and claimed in my prior patent above referred to.

As will be observed upon an inspection of Figure 5, the rubber blocks I6 and I'I do not solidly ll the housings or casings Within which they are contained but the outer ends are cut away at I6 and I1 and slight recesses |62 and i12 also formed therein. This causes the outer ends of the cushioning blocks to be more freely yieldable than the remaining portions and facilitates the closing movement of the door by permitting the wedging means, i. e., the arm I0 and latch bolt I I, to more easily pass the depending tooth I9.

The 'base or supporting plate upon which the operating parts of the lock are mounted is indicated generally at 20 and this plate is of conventional form, the main portion thereof being adapted to lie parallel to the plane of the door and an integral part 2l, disposed at approximately right angles to the main portion, being adapted to lie flush with the edge surface of the door. The supporting arm or lug I0 projects through an opening formed in part 2I` of the plate 20 and a downwardly extending portion I0' thereof is firmly secured to plate 2D by means of rivets 22 so that, base plate 20 being rigidly secured tothe door, the supporting arm I is hat.

rigid with the door.

The latch bolt member Il vof vthe wedging vmeans likewise projects through the aperture formed in the face plate 2i and its inner end is attached to the member 23, as shown ln several i'lgures of the drawings. Member 23 may be slidably mounted upon the supporting or base plate 22 in any conventional manner, has the somewhat irregular shape shown in the drawings, and is disposed in a. generally vertical plane parallel to the plate 22. The enlarged end of member 22 adjacent latch bolt li is slightly raised with respect to the remainder of the member and is disposed in a plane parallel to th remainder thereof (as viewed in Figure 1) but the member as a wholemay be described as being generally Member 22, and hence the latch bolt, is operated when the slide 2t is longitudinally reciprocated, from the position in' which" it is shown in Figures 1 and d, to the position in which it is shown in Figure 9, the latch bolt being shown as fully retracted in this last mentioned figure, a lug 25 projecting laterally from member 23 lying in the path of movement of a shoulder 26 of slide 2t' so that member 23 and slide 22 move simulslide 2t is released, therefore, both member 23 y and the slide are moved forwardlyor to the left (Figure l) by reason oi' the action of the spring 2i, and this movement continues until the latch -bolt is fully projected and occupies the position in which it is shown in Figures 1 and 4.

Retraction of the slide 2li'. in the manner just described may be edect'ed by means ofthedistant control, parts of which are shown in Figure l. A specific description of a distant control need not be given, inasmuch as it may be of conventional type, it being suiiicient for present purposes to state that the lever 32 oi this mechanism may v be manually operated to eiiect retraction of a slide 22,` through the intermediary ofthe linlr 2i, which is pivotally connected both to lever 22 and slide 2d. Normally the lever 32 occupies the positions in which it is shown-in full lines in Figure l. When the latch bolt is to be retracted by means of the distant control, the lever .itil is moved to the position in which it is shown .in dotted lines in Figure 1 and indicated at A. When the distant control is to be actuated to bring about setting of the lock so that it may not be opened from without the vehicle by the manipulation ofv the customary handle, it is moved to dotted line position B, thus thrusting outwardly or to theleft (Figure 3) the slide 24 and thereby bringing the locking lug 32 of this slide into position to prevent rotation' of the door operating handle from without, as will be hereinafter more particularly described. Slide 24 also includes an outwardly projecting portion 33 the` function of which will 'be hereinafter fully described.

Not only may the member 23 be operated by the distant control to eiect retraction of the latch bolt but it may likewise be retracted or thrust to the right (Figure 4) by the camming member 34 Yshown in Figure l.

end of member 23 when rotated in a clockwise direction (Figure 4) to therefore thrust member v:al

23 to the right and eilect retraction of the latch bolt. When camming member 34 is released it is returned automatically to the position in which it is shown in Figure 4 by the action of' 'spring 2l.. When slide 24 is moved by means of operating lever 32 and link 2i to the position in which it is shown in Figure 8, the locking lug 22 of this slide projects into the angle between arms 242 and 223, arid in this way the camming member is locked against rotation in either direction by the' slide.

Likewise the comming member 24 may be locked against rotation in either direction by a locking device which includes the vertically slidable member 22 and the cam 2i which may be 'manipulated from without the vehicle, as by means of a keyto raise slide 2t from the position in which it is shown in Figure d to the position4V in which its upper end 32' lies in the path of movement of the arm 243 of the cammina member 2t, thus preventing rotation oi the camming member and retractive movement of the latch bolt. To make itnecessary for the operator of the vehicle, in eiiecting the vehicle locking thereof, to use the hey from the outside, it is necessary to provide means for rendering the distant control mechanism ineective to accomplish locking of the camming member 2t by preventing movement of thel distant control operated slide 24 into such position that the locking lug 32 thereof moves to the ,position in which it is shown in Figure 8 when the door is open.

This means includes a sliding frame, generally indicated at i2-having a vertically extending body portion di slidably mountedV upon vertically extending prongs t2 integral ywith the face plate 2i and normally maintained inthe position in which it is shownin Figure l0, by means of a compression spring t3, the upper end of which .bears against the sliding frame and the lower end of which rests upon an inwardly projecting lug Mi integral with the face plate 2i. Sliding frame tid has a slide obstructing arm tt which normally lies in the plane of slide 2d and directly in the path of movement of the forwardly projecting portion 22A oi the slide, as Hence it is apparent that the distant control may not be so operated as to move vslide 2t into the position in which it is shown in Figure 8, so long as the sliding frame Mi occupies its normal position, thus making it impossible for a person to lock the camming member 32 against movement until the obstructing arm fit is lowered from the position in which f vided with a second arm 45 positioned 'closely adjacent the relative face of the wedging means comprising lug i0 and latch bolt il an-d normally lying immediately in rear of the latch bolt, as indicated in Figure 10. When the door is slammed and the wedging and wedge receiving means come into full engagement, as shown in Figure 5, the arm 45 of the sliding frame will be engaged by the tooth I9 as full wedging engagement of the parts is realized andwill be moved downwardly, carrying the entire frame 40 with it, the arm 45 being moved to the position in which it is shown in Figure 5 and` arm 46 to the position in which it is shown in Figures 8 and 9. With the frame in this position, therefore, the slide obstructing arm 46 is displaced from the portion 32 of the slide and the slide may therefore be advanced to the position in which it is shown in Figure 8 if desired, with portion'32 of the slide locking the camming member 34 against rotation by means of the outside door handle.

Assuming a vehicle to be equipped with locks of the character just described, it will of course be possible for the occupant to lock all the doors by setting the respective distant control devices into locking position. Obviously, however, it would be impossible for such occupant toI himself open any one of the doors from the inside in order to get out of the vehicle without first releasing the camming member 34 of one of the locks by operating the distant control device to retract the latch bolt. After having done this and opened the door, the locking slide 40 will move to the position in which it is shown in Figures 1 and 10, thus preventing setting of the' lever 30 and slide 24 to locking position. When the door is closed, therefore, it may be locked from the outside by means of a key which is provided to effect rotation of cam 31 and elevation of slide 36 into locking engagement with cam member 34, or may be locked from the inside. It may, however, be freely opened from the outside unless either locked by means-of a key or by manipulationof the same by one on the inside.

Several forms of the invention and "whereby the same objectives may be achieved are also illustrated in the drawings. In the form of the invention shown in Figures 15 and 16 the sliding frame ofthe first form of the invention is dispensed with, the means for blocking sliding movement of the slide 60, save under the conditions aforesaid, comprising an angular member 6| in the nature of a lever which is pivoted for rocking movement about the axis 62 and is normally held in its uppermost and full line position (Figure 16) by means of a. spring 63. The inner end 64 of lever 6l normally lies in the path of the forward projection 60 of slide 60 but, when the wedging and wedge receiving means are in full` engagement, the wedge receiving means acts to depress the upper end of lever 6| from its full to its dotted line position, thus elevating its lower and inner end from the position in which it is shown in full lines in Figures 15 and 16 to positions in which it is shown in dotted lines in this figure. When in dotted line position the lever cannot oppose movement of the slide' 60 toward the left (Figure 15) and hence engagement of the locking lug 65 of this slide with the slide actuating or camming member 66. As the action is generally similar to the action of the form of the invention first described, no detailed explanation is necessary.

In the form of the invention shown in Figure 17, the locking lever 10 is pivoted at 1| and normally maintained by a spring 12 in its full line position, in which position its inclined inner and edge surface 13 lies closely adjacent to the correspondingly inclined forward edge surface 'I4 of the projection 15 of the slide member 16. When the door is closed, the lever i9 is depressed by the wedge receiving means, as before, and its inner end is lifted upwardly, as indicated in dotted lines in Figure 17, its inner edge surface 13 acting as a cam as it slides along the correspondingly formed end surface 14 and slide 16 thus retracting the slide from its full line toits dotted line position and causing the lower locking lug 11 of the slide to disengage the slide camming or operating member 18.

Asimilar result is obtained in the case of the form of the invention shown in Figure 18, but in this case a frame 80 is mounted for vertical sliding movement, as was the sliding frame 40 inv the case of the form of the invention first described, the arm 8l of the vertically sliding frame, however, has its inner end edge surface 82 inclined and adapted to slidably engage the correspondingly inclined edge surface 83 of the slide 44 as it moves from its full to its dotted line position, thus camming the slide 84' to the right (Figure 18) from full to dotted line position and formed in two parts; the block 90 being centrally mounted in a vertical slot in the rocking mem ber 9|, and pivotally connected thereto at 92 so that it may be oscillated in a vertical plane. Rocking member 9| carries a downwardly projecting tooth 93 at its free end and is normally pressed downwardly by means of a coiled compression spring 94. The tooth 93 is adapted to bear down and actuate any one of the several levers illustrated in the preceding figures of the drawings. By reason of 'the mounting of the tooth upon the rocking member 9| this tooth may have a relatively different vertical movement without necessitating simultaneous and equal movement of the jaw 90. Other forms of the invention may be devised to state the circumstances of particular cases, as will be apparent to one skilledin the art.
