4- Claims.

This invention relates to coincidental locks for the doors of automobile bodies. It has already been proposed to coincidentally look all the doors of an automobile from one point, Hardesty Reissue 19.073. It has also been proposed to mechanically coincidentally dog all the outside handles or declutch all the outside handles of an automobile body by means of operating connections which are worked by turning the outside door handle.

It is also old to operate a trigger or push button when the door is opened and then turn the outside handle down and close the door, thus utilizing the power of closing the door for operating shifting devices on the center pillars for looking or making ineffective the locks on the other doors. This is shown and claimed in my prior application, Andersen, Serial No. 110,253, filed November 11, 1936. However, in my said prior application, the only way that the locking system can be operated from one point on the inside is by a small snap-tite lever on the inside of the door. This is a small lever very similar to the small levers that are used on electrio light switches. It is not of suflicient size and mechanical advantage to be very useful in attempting to operate all connections for making ineffective all the outside door handles on the car.

It is the object of the present invention to utilize the inside door handle in coincidental looking from the inside to furnish the power with which to make ineffective all the other door handles on the body.

In the drawings:

Fig. 1 is a perspective of a body equipped with my improved locking system, part of the body is broken away.

Fig. 2 is an enlarged detail view, partly in section, showing the front curb door lock and the rear curb door lock and the interconnecting mechamsm.

Fig. 3 is a similar view showing the looks after being set to make the outside handles inefl'ective.

Fig. 4 is a view looking upwardly at the curb front door lock, shown in Fig. 3.

Fig. 5 shows the door locks on the off-curb side of the body.

Fig. 6 shows the same locks after they have been actuated to make the outside handle ineffective.

Fig. 7 is a view looking upwardly at the lock shown in the left in Fig. 6.

Fig. 8 is a fragmentary side elevation of the car showing how the operator first pushes down the button on the garnish molding and then turns the outside handle before closing the door to effect the locking operation.

The lock involved in this application is of th Andersen and Bowlus type, described and claimed broadly in the Andersen and Bowlus Patent No. 5 2,039,873. This operates on the principle of rendering the outside door handle ineffective by disconnecting it from the bolt. To do this, the push button I on the garnish molding is pushed down (see Fig. 8). This has a rod 2 (Fig. 2) which 10 pushes down lever 3 and this carries with it lever 4 which is the operating connection between the rollback 5 and the abutment 6 on sliding bolt 1. When lever 4 is in its lowered position (as shown in Fig. 3), the beveled lug a is adapted to be contacted by the beveled end 9 of the lug carried by the sliding bolt. This serves to cam the lever 4 back to its operative position. So every time the door is closed, the operating connections are automatically cammed back into operating relation unless it be that in closing the door, the operator turns down the outside handle (as shown in Fig. 8). In that event, there is no camming the lever 4 back to operative relation. The reason for this is that when the handle is turned 25 down, the rollback forces lever 4 backwardly (shown in Fig. 3) and out of the range of the camming action of the beveled surface 9. This is fully explained in the Andersen and Bowlus patent supra. 30 To get into the car, the key lock in the front curb door is operated and it shifts the key bolt ID. This forces the lever 3 up, carrying the operating lever 4 with it, and reestablishes the connection. At the same time, this removes the device which holds all the other locks in locked position and they all automatically spring back to positions which make the outside door handles effective which will be explained hereinafter.

Supposing that one desires to get out of the 40 car and lock all of the doors: He pushes down on button I (as shown in Fig. 8). That carries the lever 4 down to the position shown in Fig, 3. That sets it in the path of the end llof the 0 lever l2 which is part of the toggle I3. Hence, when one turns down the lever of the outside handle (as shown in Fig. 8) and closes the door, he not only forces the cam surface 8 out of the range of the beveled surface 9 so as to preclude the forcing of the connecting parts back to op-' 50 erative position, but he also forces back the C lever l2 forcing the toggle 13 to the up position (as shown in Fig. 3). In fact, Fig. 3 shows this very action being effected. The pin 20 passing through the selvage plate I4 is forced down (as u shown in Fig. 3). when that strikes the transmission lever II on the inside of the body pillar, that cams this lever to the down position (shown in Fig. 3). This pushes down the bell crank lever I! from the position shown in Fig. 2 to that shown in Fig. 3. .This lifts the opposed lever Ila on the oppositeside of the center pillar, tilting it in just the opposite direction, raising pin 2041 that protrudes through the selvage plate, and depressing toggle ll shown in Fig, 2 to the position shown in Fig. 3. The depression of the toggle pulls down the elbow-like link 22 which, in turn, pulls down the lever 3 of that particular lock which, in turn, pulls down operating lever 4 and disconnects the rollback from the sliding bolt so as to make the outside handle a semi-freewheeling handle and ineflective to retract the bolt.

At the same time that the bell crank lever II operates the lock which is a companion lock on the center pillar, it operates another bell crank 23 which operates the draft rod 24 that goes up through the center pillar and has a cable con nection 25 with the opposite side of the body (see Fig. 1). Now referring to Figs. 5 and 6, it will be seen what happens on the opposite side of the body: Cable 25 pulls the slide 26 up, from the position shown in Fig. 5, to that shown in Fig. 6. This breaks both toggles I I downwardly which in turn, as already explained, pulls the operating lever 4 out of the range of abutment 6 of the sliding bolt. So both of these locks are now out of connection with the outside handles and these are semi-free wheeling and ineffectual to retract the lock.

Now the improvement that I have here made over my prior application, Serial No. 110,253, is that by reversing the retracting movement of the inside pull-to handle 2'! (Fig. 1) the draft connection 28 may he moved forward from the position shown in Fig. 2 to that shown in the dotted lines in Fig. 3. This pushes back the lever 29 which throws the large C lever l2 and forces toggle i3 up (as shown in Fig. 3). If the inside push button i has been first pushed down, the lower jaw 30 of the C lever will ride under the lug 3i (as shown in the dotted lines of Fig. 2) and then when the jaw has passedbeyond lug 3|, this lug will snap in front of it and hold the toggle i3 in the up position (as shown in Fig. 3), spring 32 furnishing the small spring action to force the lever 3 down the rest of the way to snap in front of the jaw of clever II. The striker pin 20 will force down the end of lever l5 and operate the several other locks in the same way that happens when the striking pin is already depressed with the door open. The door is closed and the striker pin then earns the transmission lever l5 down to make ineffective and hold ineffective all the other outside door handles.

The value of this locking system is that it is operable wholly mechanically from the outside or inside from one point and by means of a member already on the car door which aifords considerable leverage to operate the numerous transmission connections. When one gets out of the car, he pushes down button I with the door open (as shown in Fig. 8). He then turns down the handle (as shown in Fig. 8) and with the handle so turned down, slams the door shut. This automatically locks every door lock in the car by reason of the connections that have already been described.

One can-also lock the door after it is closed by inserting a key in the lock and throwing the lever 3 down so that it carries the push link 4 from the position shown in Fig. 2 to the position shown in Fig. 3. When in this position, the outside rollback is turned as it is shown turned in Fig. 3. This rocks the c lever l2, operating the striking pin 20, and through this the remote connections to operate the outside handle controls of all the locks.

To get into the car, one inserts a key in the lock in the usual way, throwing the lock cylinder and crank pin 34 (shown in Fig. 2). This depresses key bolt l0, forcing up lever 3 which carries lever 4 up with it and reestablishes the operating connection with the front curb door lock so one could turn the outside door handle to retract the bolt and get in through the front curb door opening. The pressing down of the button I on the front curb lock not only sets that particular lock to make the outside handle ineffective but the small lug 3! is ready to drop in the head of the lower jaw of the c lever if (as shown in Fig. 3). This holds all the other locks in the set position which renders the outside door handles ineffective. However, this catch II can be easily tripped when the key is used from the outside to release the front curb door lock. Immediately upon the throwing up of this lever 3. the spring 35 of the toggle ii on the front curb door lock and the springs 36 of the toggles I! on the other door locks immediately shifts the parts of those looks so that the operating levers 4 are again connected with the latch bolts to make the outside handles effective to retract the bolts. The draft connections are also shifted back to their original positions.

This arrangement is an improvement over my prior application because in that case it was necessary for the key to have a direct connection with all the locks to release them, aided, as stated in that application, possibly by springs to help the key return the locks to a position of effectiveness for their outside handles. In the present improvement, the key has no connection whatever with the other locks. It merely releases the curb door lock and removes the lug 3| that holds these other: locks in the set position. The springs 36 which are connected with the toggles do the rest in returning the parts to their position of operative relation with respect to the outside door handles.

Assuming now that the door is again closed and the driver desires to protect himself and other occupants against the red light bandit 'by locking himself in the car: He first snaps down the push button I on the curb door lock. He then turns forward the inside remote door handle 21. This pushes draft link 28 forward, lever 29 forward, pulling the C lever l2 backward, breaking toggle i3 upwardly, until lug 3i snaps in front of lower jaw of c lever (as shown in Fig. 3). In the meantime, striker pin 20 has been forced down, operating transmission levers i5 and Ho, bell crank l1, and the connections 24 and 25 to the opposite side of the car where, slide 26 makes ineffective the doorhandles on the opposite side of the car to retract their lock bolts.

The mechanism that we have here to deal with involves so many complexities and so many overlapping functions that it seems well to group together some of the elements and give to each group a specified name that is calculated to clearly identify the mechanism and the function performed. This name will be carried into the claims so as to make clear what particular set of elements in the drawings of this application will support the claims. By this arrangement, I do not intend in any way to limit myself to any special group of elements in the drawings of this case which will support the claims. I am simply doing this for convenience in finding a specific support for the claims in the drawings. For instance, each of the locks has a means for rendering the outside door handle inefiective to retract the bolt. In a good many locks now on the market, this is a dog which looks the outside rollback. In this particular application, it is the operating lever 4 which may be drawn out of connection with the latch bolt by shifting of the lever 3. Hence, in this particular lock, the levers 3 and 4 are the outside-handlecontrol."

The mechanism which is calculated to control the outside-handle-control of each lock from asingle remote point involves a large lever l2 with several sets of toggle arms l3 and I8 and the elbow-like links 22, the transmission levers i and l5a, strikers 20 and 20a, bell crank levers I1, 23,v the draft connections 24, 25, the slide 26, the strikers 20b, the elbow links 22b and the transmission levers l5b. These elements represent connections for efiecting remote control of the outside-handle-controls which will be given the designation remote-connections. The front curb lock has a lever 3 operated by the key which is provided with the holding lug 3|. This particular lever and its companion lever 4 will be referred to in the claims as the "masteroutside-handle-control for it is this lever that has a very important element in this combination, to-wit: the lug 3| which can hold all the other outside-handle-controls and remote-connections under restraint. Springs 35 and 36 covering the several toggles will immediately return the outside-handle-controls to a position wherein the handles may operate the latch bolts when this lug 3| is removed from the large 0 lever l2. Hence, this element 3| will be designated in the claims as a holding-device and the springs 35 and 36 will be referred to as spring means.

1. In a coincidental locking system for vehicles, the combination with a body provided with a plurality of doors, each door provided with a lock having an outside handle, a latch bolt and an outside-handle-control, of an entirely mechanical coincidental locking system, comprising remote-connections for operating a plurality of said outside-handle-controls from one point, spring means tending to return said outsidehandle-controls and remote-connections to initial position, means by which said remote-connections and said outside-handle-controls may be set to render the outside handles inoperative to retract the bolts, a holding-device for keeping them so set and means operable fromthe outside of the door by which said holding-device may be released to let the springs return the remote-connections and the outside-handlecontrols to their initial positions, said remoteconnections having a plurality of toggles and said spring means normally tending to throw each toggle from one side to the other of its center-line.
