(Cl. 292-453) This invention relates to motor vehicles, and mands, and yet will not materially add to the expense of building the vehicle. particularly to the locking mechanism thereof. Another object of the invention is to provide The present-day conventional automobile door locking mechanism comprisesv a latch boit for a locking mechanism for motor vehicles that side of the door. ' The inside handle, or some Another object of the invention'is to provide a locking mechanism by which one of the doors of 5 each doorwhich may be `operated by a handle on will facilitate locking all of the doors either `from the outside of the door or by a handle on the in ' the inside or the outside. other device on the inside oi' the door, may be moved to _a locking position so that the latch 10 bolt may be locked against operation from the outside. This permits the operator on the inside to individually lock all four doors .against out side intrusion. Usually the right front door ls provided with an outside key-operated lock for l5 locking the latch bolt of` that door against re traction. Thus the operator may lock the other three doors of a four-door vehicle before he leaves the vehicle and then lock the right front door on the outside, thus securing all four doors against outside intrusion. a motor vehicle will be locked when another ad- jacent door is closed. - Another object `of the invention is to provide a locking mechanism for adjacent doors >whereby the latch bolt of one door is locked by the latch bolt of the adjacent door. Another object of the invention is to provide 15 an interlocking mechanismy between adjacent doors which may be moved to and held in an in operative position, so that the doors may be op erated without the interlocking mechanism. Another object of the invention is to provide ° door interlocking means in which there are rioV There is a demand by some motor vehicle own additional projecting parts. ers for an additional locking means for the rear ` Other objects of the invention will appear from doors, a locking means that cannot be opened by children in the rear`compartment, because the following description taken from the draw ing forming a part of this specification and in which: Fig. 1 is a horizontal sectional view through adjacent doors and the door pillar of a motor vehicle, showing one form of `the invention, both 35 these owners feel that vchildren are not safe in the rear compartment with the present locks. due tothe fact that even when the rear door handles are placed in locked'posltlon, they are easily operated and the doors can be opened n by children: If this is done when the vehicle is >doors being in fully closed position.

Thus it is desirable that the rear doors may be locked without reaching over the back of l locked then the four doors of the vehicle can y be more easily locked from the inside and three 40 of them can be locked from the inside and the fourth from the outside with a key, so that both forms of locking are more easily accomplished. It is also believed that some motor vehicle owners prefer the present individual door lock ` ß ing mechanism and particularly is this true with chauiîeur-driven vehicles. ‘ ` , ' With these conflicting preferences, the man# ufacturer would have to have several different forms of locks and give the purchaser the option 5_0 of choosing which of them he would have, and this would increase the cost and add to the diiil vculties of the sale of vehicles./ - Fig. 4 is a section, substantially on the line 4-4 of Fig. 1. the front seat and if the rear doors can be so c Fig. 2 is similar to Fig.. 1, with one of the doors unlatched.

Referring to the drawing, I0' represents that portion of a motor vehicle forming the post or pillar between two of the doors. It is shown as built up of a channel member II and a shallower channel member l2' which are .welded or other 50 ` wise secured together. A strip oi wood I3 is ar- ,_ ranged in the channel of the member I2 for sound-deadening purposes and for attachment of upholstery. - . ' I Two of the doors of the vehicle close against 55 2 2,127,543 the post Il, and in the drawing the front door is indicated at I4 and the rear door at I5. In addition, these doors are marked “front” and “rear.” Cil On the rear door side of the pillar II is the usual'keeper or striker plate I6 secured to- the pillar as by screws I1 threaded through the sheet metal of the pillar and into a threaded block I8 welded or otherwise secured to the pillar.- A 10 keeper or striker plate I9 is similarly secured to the pillar Il on the front door side thereof. turn the dog on its axis. As this turning move ment takes place the hooked end 4I at the other end of the dog moves to its horizontal position _ into the recess 5I of the latch bolt 30. Of course this movement is again the action of the spring 41, which is thereby coiled to some extent, and upon withdrawal of the latch bolt 22 the spring 41 returns the dog 4010 its former position, in which the hooked end 4I is entirely out of the re cess 5I and Within the _confines of the notch 2 l ' òf 10 and the second notch 2l and the plate I9 hav ing ñrst notch 20’ and second notch 2|', the lirst notch of each plate being for the purpose of re the striker plate. From the above description it will be seen that with the rear door closed the act of closing the front door will lock the rear door. Thus, with the latch bolt 30 in the position shown in Fig. l, 15 the closing of the front door will cause the latch taining the door in its nearly closed position if, bolt 22 to ride over the notch 2| and move rear Each of the'striker plates has the usual two notches, the plate I6 having the ñrst notch 20 for anyreason, it fails to catch on the second wardly, so that its beveled face 52 will contact with the end 42 of the dog and rotate the latter, 20 The front door I 4l has the usual sliding latch so that the hooked end 4I thereof will enter the 20 bolt 22 spring pressed outwardly towards the ‘ recess 5I of the latch bolt 30. As long as the dog pillar II by the usual spring 23 and guided by a is in that position the latch bolt 30 cannot be pin 24 operating in a slot 25. 'I‘his pin also limits withdrawn by operation of either of its hand the inward and outward movement of the latch operated devices, that is, it cannot be Withdrawn bolt. The outer end of the latch bolt 22 is curved by operation of either the outside door handle or 25 or beveled as at 26, so that it will slide over the the inside door handle. To unlock the rear door, striker plate in the usual way- when the door is the front door latch bolt must be withdrawn, and . notch. closed. this can be done only in case the front door latch . The usual means for retracting the latch bolt 30 may be connected thereto, and in Fig. l of the drawing an outside door handle 21 is shown, hav ing a shank 28 connected by the usual means (not shown) for retracting the latch bolt, and a link 29 adapted for inside manipulation, for the same 35 purpose. ` On theother, or rear side of the pillar 'I I, the ~ rear door is provided with a sliding latch bolt 30 similar> to the latch bolt 22 of the front door, and there is also a similar door handle shank 3l and 40 an inside door releasing means similar to those on the front door, for operating this bolt. Also, the front door may be provided with the usual key locking mechanism, not shown. . The interlocking means of this invention is ' shown in Fig. 1 in the form of a dog 40 having a hooked portion 4I at its rear end and a bent end bolt is not locked by its key-controlled mecha nism. If not so locked, the latch bolt 22 may be 30 withdrawn by operation of either the inside or outside door handle, and as it is withdrawn the spring 41 returns the dog 40 to its unlocked posi tion, as shown in Fig. 2, the hooked end 4I then extending vertically downward and out of the re 35 cess 5I. In that position ofthe dog the latch bolt 30 may be withdrawn by either of the hand operated means. Should the front door be closed before the rear door is closed, the hooked end 4I of the dog 40 40 will, of course, be in the position shown in Fig. 1, and as the rear door is then closed the latch bolt 30 will move ~forwardly and the beveled portion 50 thereof will engage the hooked end 4I of the dog 40 and further rotate the dog against the spring 42 at its forward end, the end 42 extending ap 41 until the end 4I slides over the beveled surface 50 into the recess 5I. The latch bolt 30 will then proximately 90 degrees from> the direction of the4 be locked against withdrawal until the front door hooked end 4I. The intermediate shaft portion 50 43 of the dog extends through openings 44 in the pillar I0 and is provided with shoulders 45 which abut against plates 46 which are welded or other wise secured to the pillar, so that the dog may ro tate on its longitudinal axis, but is prevented from 55 being moved axially with relation to the pillar. 'I'he dog 40 is yieldingly held by a ilat spring 41 to one end of which it is secured as by a rivet 48 and the other end of which abuts against a por tion of the pillar as shown at 49 in Fig. 3. With 60 this spring construction the dog 40 may be ro-_ tated through 180 degrees and the spring 41 will return it toits original position when released. The latch bolt 30 of the rear door has the upper part of its forward end formed with a beveled surface 50, and just back of the beveled surface is latch bolt is withdrawn as above described. Should it be desirable to disconnect the inter locking device, this may be done in the present in vention, thereby making the latching mechanisms of the two doors independent of each other. With the front door open the dog 4l) may be rotated 180 degrees from the position shown in Fig. 2 to the 55 position shown in Fig. 6. And the dog may then be held in that position by a catch 53 pivoted at 54 and having a ñange 55 at its outer end for operating. Thiscatch 53 will prevent the dog 40 from being reversely rotated by the spring 41, and 60 as long as the dog is in the position shown in Fig. 6 there will be no interlocking action between the latch bolts of the doors. This position of the catch 53 is shown in Fig. 6. If the catch 53 is returned to the position shown in Fig. 1 the inter a recess 5I into which the hooked end 4I of the locking dog will immediately return to its opera dog 40 may extend when it is not in its‘horizontal, - tive position and will again act to lock the rear position. It is shown in _that position in Fig. 1," door when the front door is closed. and likewise in Fig. 9. 70 _ 'I'he latch bolt 22 of the front--door also has its end beveled as at 52 and the relationship of this bolt to the dog 40 is such that, as the bolt moves past the notch 2|', the bent end 42 of the dog will contact with the beveled part 52 of the latch bolt 75 22 and thereby push the bent end upwardly and 50 It will be noted that this interlocking mecha nism is entirely within the margins of the striker plate, and there is nothing projecting from the edges of the door except the usual latch bolt, so that there is nothing‘additional to catch the clothing of a person entering or leaving the vehicle. 3 2,127,543 end 4| extending downwardly so that it does not enter the recess 5l of the latch bolt 30.

In a motor vehicle, the combination of front and rear doors, each door having a latch bolt, and means extending from one latch bolt to the other for locking one of said doors by the move ment of a part of the other door movable relative end 42 is in .a position to be operated upon by to said other door. The three positions of the interlocking device are well shown in Figs. 8, 9, and 10. In Fig. 8 the dog is in its non-locking position, the hooked the latch bolt 22 when the front -door`is closed. " \In Fig. 9 the front door has been closed and the beveled surface 52 _of the latch bolt 22 has turned 10 the dog 40 so that its bent end 42 extends up wardly and its hooked end 4I is in the recess 5i of the bolt 3l), thus locking the bolt 30 to the striker plate and preventing it from being With drawn by the usual hand-operated means. The 15 locking dog and its associated parts are of suffi cient strength relative to the bolt operating means that the latter will be broken or disabled before the locking dog will give way. In Fig, 10 (and in Fig. 6 also) the dog 40 has been turned to its 20 inoperative position, where it- may be held by the catch 53 above referred to, and in this position the doors may be independently operated. While I have herein described in some detail a specific embodiment of my invention, which I 25 deem to be new and advantageous and may spe ciflcally claim, I do not desire it to be under stood that my invention is limited to the exact details of the construction, as it will be apparent that changes may be made therein without de 30 parting from the spirit or scope of my invention. What I claim is: , 1, In a. motor vehicle, the combination with` two doors each having a latch bolt, of locking means for one of the doors comprising a rotat 35 ingl dog operated by one of the latch bolts to lock the other latch bolt. ' 2.
