s cum. (a. -264) This invention relates to coach 'locks and has for its object a so-called coincidentallock, that is, one in which two or more'of theIdo r lOcks may be coincidentally dogged.

locks in one operation (see Hardesty Reissue No. 19,073). It has also'been proposed to coincidentally dog two or more locks mechanically by the aid of the outside door handle.- In me'chanically dogging two or more looks, it has been found that the ordinary key does not supply sum cient mechanical power to easily operate the con-H J nections. Hence, it has been proposed tomsea key connection and the reverse rotatiorfof the door handle to effect this object jl'fi present 'improvement seeks to accomplish the same general result by using an inside dog controller or an outside operated key-cylinder in connection" with the power furnished by the closing of the door to effect this object.

This invention utilizes the locking principle of the Andersen and Bowlus Patent 2939373 in connection with the key operated lock which is normally the front curb door lock.' Preferably, the locks on the other doors are also theAndersen and 'Bowlustype of looks; but this is not necessarily so as it would be possible to equipthe other doors with the conventional blocking type of dog or with any other form of so-called freewheeling handle look. But we preferto utilize the Andersen and Bowlus type of lock on all the doors and the explanations will be in connection with such a form of i look.

is. alongitudinal section or the cylinder T e details of the Anderson and Bowlus lock 1 are described in Patent 2,039,873 and need not be described here except in a'general way. These locks are now used on many cars and a great many of the motoring public are familiar with their operation. A snap button or 'a push pin is used to control the lock on the inside. The lock is of the semi-freewheeling handle type which is desirable'to prevent the forcing of the. look from the outside. When one is in the car and desires the button or pushes down on the pin. This disconnects the outside handle from the latch bolt and the outside handle turns freely through a part of a turn without operating anything. In order to make this form of locking device safe from accidentallylocking ones self out of the'car, a cam arrangement is provided so that each time the inside operating handle retracts the bolt or the bolt is retracted by slamming the door closed, the operating parts are automatically reengaged so that the outside handle will retract the latch bolt. This is an old device that has long been used in connection with dogging devices on automobile doors.

The Andersen and Bowlus improvement begins here. By an arrangement of operatingconnections, Andersen and Bowlus have made it possible by suitable manipulation from the outside of the-car to prevent the automatic resetting 40 of the operating connections which normally takes place when the door is slammed shut.

Hence, when one gets out of the car, opens; the

door, sets the inside controlling evice to the locking position-and then slams the oor' shut and at the same time manipulates thisgdevice to pre-. vent a resetting of the operating connections the door becomes locked without the use of a key. It has been found desirable to have the outside device that prevents the resetting of the operating connection take the form of turning the semifreewheeling handle down to the position shown in Fig.9 and then slamming the door shut with the handle in such turned down position.

The details of how this is effected are briefly 65 7 these: Referring to Fig. 5, I designates the out- .-by means of the outside rollback side rollback which bears against the lower end of a lever 2, the upper end of which receives pressure from the end of a spiral spring 3 carried on the inside of the sliding latch bolt 4. 5 is a slide pivoted at 6 to the lower end of the lever 2. The other end of the slide when in the position shown in Fig. 5 is adapted to bear against the abutment I of the latch bolt and retract the latch bolt when the slide is retracted This slide has a lug 8 which projects through the slot 5 of the lock-setting arm l0. Thisarm is pivoted at H to the rollback casing l2. Its other end is slotted as at l3 through which the button i4 projects to form a guide. I5 is an over center spring which holds the arm either in the extreme upper or lower position when this is operated by the strap i6 connected with the snap button or control lever With the snap button or control lever il in the position shown in Fig. 7, the operating connections are set to retract the bolt but with the operating connections shown in Fig. 8 and the snap button in the down position the outside handle is in its semi-freewheeling condition such as that shown in Fig. 9. Ii! one attempts to retract the bolt with the parts as shown in Fig. 8, the slide simply moves inoperatively from the position shown in the full lines to the position shown in the dotted lines and designated IS. The automatic resetting device consists of the arm which has the cam face 2| adapted to engage under the lug 22 (Fig. 8). When the latch bolt is retracted in any way, whether by the inside retractor (which is not shown) or by means of the latch bolt head riding over the'striker, the cam 2| will engage under the lug 22 and snap the lock-resetting arm back to the position shown in Fig. 7.. The Andersen and Bowlus invention consists of providing a device to be manipulated from the outside to prevent this automatic resetting operation and specifically consists in simply turning the handle down as shown in Fig. 9 and holding it in this position while the door is closed. This causes the rollback to move the slide from the position shown in Fig. 8, full lines to the position shown in I! in the dotted line 01' Fig. 8. Hence, when the bolt is retracted in any manner and particularly by closing of the door, the ing 22 is out of the range of the cam 2| and consequently this cannot throw the lock-setting arm back over center to reestablish the operating connections between the outside handle and the latch bolt. 4

The present improvement and invention begins here. The end of the lock resetting arm III instead of lying behind the selvage plate 23 passes through the selvage plate as shown by the dotted lines of Fig. 5 at 24 and also in Fig. 6A. The end is in the form of a little nub 25 whichengages in a slot 26 in. the swinging segment 21. A second segment 28 is pivoted on the outside of the swinging segment 21 and is adjustable with respect thereto by the screw and slot connection 29 and 30. This enables the striker pin or interengaging member 3| to be adjusted with respect to the swinging segment to bring it into accurate relation with the motion-transmitting slide 32. This motion-transmitting slide is wrapped around the inside face and two sides of the center pillar 33. See Figs. 2, 3 and 4. The plate 34- (Fig. 3) secured to the center pillar, carries a pair of rivets 35 and these engage in a slot 36 in the motion-transmitting slide. A cover plate for the slot is afforded by the steel strap 31. This also furnishes the necessary friction to keep the slide in either of its positions of travel. The slide is provided on each side with a pair oi. flared mouth keeper sockets designated 38. These are adapted to receive the striker pin 3|.

The operation is as'tollows: One opens either of the doors on one side of the car for the purpose oi getting out, this automatically resets the operating connections provided the inside controlling lever has been set. When the door is opened, one sets the inside button I! to the on position which is that shown in Fig. 8. This depresses the inside end of the lock setting arm l0 and it raises the outside arm with the striker pin 3|. If the door is open, this pin will not be in contact with the motion-transmitting slide 32. The other door will have the pin 3| engaging the flared socket at the motion-transmitting lide as shown in Fig.4. With the pin 3| now in the'up" position as shown by the dotted lines designated 33 in Fig. 2, the pin when the door is closed, will strike the upper flare or cam 40 (see Fig. 4). This will cause the slide to rise as shown by the dotted lines 4| in Fig. 2. This will carry the other striker pin together with the swinging

segments

21 and 23 of this look to the upper position, thereby raising the outer end of the setting arm Ill and pressing down the inner end of the arm l0 and thereby disconnecting the operating connections from the other latch bolt. Slide 5, when the outside door handle is turned, will pass to the dotted line position shown in Fig. 8 and designated 9. In this position, slide 5 and consequently lever l0 and striker pin 3| are locked because the lug 22 on slide 5 engages under the turned over lug of the lock casing. Hence, the striker pin 3| is capable of throwing all the parts, including remote connections, without being displaced. Hence, here one has the two locks on one side of the car both locked when one lock is locked and in accordance with the principle 01' the Andersen and Bowlus patent. By using a strong push and pull wire 42, as shown in Fig. 10, this operation can not only lock both the locks on one side but the locks on the opposite side of the car as shown in Fig. 10. It will be necessary to use a reversing lever 43 to reverse the motion so both of the slides will go up together. The showing in Fig. 10 is simply diagrammatic and is not to be taken as the form that the device would take for actual commercial production.

It will be obvious that all the locks, whether there are two or four, will be mechanically shifted when any one of the inside operating buttons or levers i1 is shifted with all the doors closed or when the key 44 (Fig. 11) is operated from the outside to turn cylinder lock 45 which through crank pin 41 shifts the lock bolt 46 of the curb lock (Fig. 5). Since the key is a difficult instrument to turn where ,there'are small locks to be operated, it is possible to provide springs which will tend to return each of the resetting arms to position to retract the bolt when the key provides the small additional power necessary to turn the arm over center.
