4 Claims.

This invention relates to new and useful improvements in an automatic four door lock for.

automobiles.

The invention has for an object the associall tion of mechanism with the four locks of the four doors of an automobile arranged in a manner so that the four locks may be locked simultaneously. The advantage of this arrangement resides in the convenience with which the doors may be locked merely by operating one look.

Still further the invention contemplates a construction characterized by the use of flexible cables for transmitting the locking motion between the locks so that they may work in unison.

w Another object of this invention resides in providing a toggle construction disposed between the front and rear doors at each of the sides of the automabile and arranged and connected with mechanism in .a manner for controlling the bolts gg of the locks.

Another object of this invention resides in the provision of a manual means independent of the key controlled means for locking the locks and operative from within the vehicle body for moving one of the toggles previously mentioned for opening its associated lock in case of emergency.

Another object of the invention resides in providing locking mechanism for the windows of the vehicle also controlled by the door locking mechanism.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

u The automatic'four door lock for automobiles,

according to this invention, is used in combination with an automobile body It] having right side front and rear doors II and II respectively, and left side front and rear doors l3 and I4 respectively. These doors are provided with lock- 5 ing bolts I5, i6, i7 and I8, respectively. Each of these doors is of the hinge type and at their remote edges are provided with hinges 20 by which the doors are hingedly supported to swing open and close. Each of these doors work in a door jamb of the automobile. The doors at the right side of the automobile body are separated by a jamb partition 2i and the doors at the left side are separated by a jamb partition 22. w

A key operated cylinder lock 23 is mounted upon the'jamb partition 2!. This lock is of the type having a rearward extending rod 23 for working the bolt mechanism of the door locks. The rod 23* is of elongated shape in cross section and 2c is adapted to engage in the elongated opening 23" of a rotatively supported gear 2 3. This gear is in mesh with a gear 25 rotatively supported and meshing with a rack 26. The rack Ed is connected with a vertically slidably mounted bar El. 25 This bar is supported by several bolts 28 mounted upon the material of the jamb partition 2! and working in vertical slots 29 formed in the bar.

A toggle mechanism is disposed within the jamb partition 25 for locking and opening the bolts id as and i6 respectively. This toggle mechanism includes arms 3!] and 3 i. These arms at their inner ends are pivotally mounted on a spindle 32 which extends through the bar 2i. At this point the bar is formed with a slot 33 the base portion of 35 which is formed with an enlarged recessed opening 36.

A collar 35 is mounted on the spindle 32 and normally is disposed within the recess 36. An expansion spring 36 is arranged axially on the id spindle 32 and acts between a head 3i formed on the inner end of the spindle and one side of the bar 2'! for normally urging the collar 33 into engagement within the enlarged recess 34. The inner end of the spindle 32 is provided with a 45 head 38 by which it may be manually moved. The arrangement is such that the head 38 may be pulled to compress the spring 36 and to move the collar 35 out from the recess 34. Then the toggle arms 36 and 3i are relatively free from the bar 21 50 and the spindle 32 may move along the slot 33.

Levers 39 and 40 are pivotally supported at their upper ends by pintles 4!. Intermediate of their ends these levers are pivotally connected by pintles 42 with the toggle arms 30 and 3|. The

lower ends of the levers 39 and 40 are formed with forked portions 39- and 46 respectively, engaging pins 43 mounted on brackets 44 which in turn are respectively mounted on the bolts l5 and i6. Each of these bolts has a slot 45 through which a supporting fastening element 46 passes to assist in horizontally slidably supporting thd bolts. A cable 41 is connected with the upper end of the bar 21 and extends through stationary casing 48 which is'guided within the roof of the vehicle body "I.

When the gear 24 is turned by the cylinder lock the motion will be transmitted to move the rack 26 downwards. This indirectly moves the toggle arms 30 and 3| downwards at their inner ends so that their outer ends spread the levers 39 and 40. This motion extends the bolts I5 and I6 into the keepers for the bolts arranged upon the doors H and i2. The bolts [5 and I5 may be opened by operating the cylinder lock in the opposite direction to rotate the gear 24 back to its original position. It is pointed out that when the bar 21 is in its lowered position in which the bolts I5 and I6 are in their locked positions, it is possible to operate the emergency handle 38 to relatively disconnect the upper ends of the toggle arms 30 and 3| from the bar 21 and then the spindle 32 may be moved upwards to manually move the toggle arms 30 and 3| and so indirectly retract the bolts l5 and i5.

The bolts l1 and I8 are operated in a manner very similar to the bolts l5 and I6. Within the jamb partition 22 there is a vertically slidably mounted bar 21 which is supported by several bolts 28' working in slots 29 formed in the bar 21'. The top end of the bar 21' is connected with the flexible cable 41 so that when the bar 21 moves downwards the bar 21 will be moved upwards. Toggle arms 30' and 3| are pivotally connected at their inner ends by a pin 32' mounted on the bar 21'. The outer ends of the toggle arms are connected by pintles 42' with intermediate portions of levers 39' and 40'. These levers are pivotally supported at their lower ends by pintles M. The upper ends of these levers have forked portions 39* and 30, respectively. These forked portions engage pintles 43' mounted on brackets 44 which are directly supported on the bolts 11 and I8 respectively. Each of these bolts operate horizontally. Fastening elements 46 working in slots 45 formed in the bolts assist in supporting the bolts horizontally. When the cable 41 moves the bar 21' upwards the bolts l1 and I8 will be extended to their looking position and when the bar 21' is moved downwards the bolts will be moved back to their open positions.

Each of the doors is provided with a window 50 associated with mechanism for moving the window upwards and downwards controlled by the conventional turnable handle 5|. The details of this mechanism will not be given in this specification since such mechanism is generally known in the art and is of the type shown in the patent issued to Jesse G. Vincent, No. 2,053,854, on September 8, 1936. However, a locking means is associated with each of the doors operated by the bolt of the door for locking the window 50 from being opened. This means includes a ratchet wheel 52 mounted on each handle 5|. An arcuate pawl 53 is adjacent each ratchet Wheel 52 and is slidably supported by fastening elements 54 working in horizontal slots 55 formed in a tail portion 53 of the arcuate pawl.

A spring 56 acts to normally hold the arcuate pawl 53 from the ratchet wheel 52. Each tail portion 53 is provided with a rod 55 which slidably extends into a bracket 51. A spring 58 is mounted upon the rod 55 and normally tends to separate the bracket 51 from the tail portion 53. The bracket 51 is disposed immediately adjacent the bolt of the particular door. The rod 56 has a cross head 56 working in a slot 59 formed in the bracket 51 for slidably supporting the bracket. When the lock is opened the parts are as shown upon the drawing. However, when the bolt of any particular door is closed it will move the bracket 51 of the window locking mechanism inwards. This motion is transmitted by the spring 58 which is a relatively stifi spring as compared with the spring 56. The motion wi l therefore be transmitted to the arcuate pawl 53 which then acts against the ratchet wheel 52. The arrangement is such that the handle 5] may still be turned to close the window since the ratchet teeth will then slide past each other. But the window cannot be opened because the teeth engage each other. It is necessary that the bolt be first moved to an unlocked position before the window may be opened. The particular window locking mechanism is identical for each of the four doors.

The operation of the device is as follows:

When the doors of the automobile body are closed they may be simultaneously locked by operating the cylinder lock 23. This look, when moved to the closed position, moves the bar 21 downwards. This motion is transmitted by the cable 41 to move the bar 21' upwards. The motion of these bars operates the toggle levers 39 and 3| and 30 and 3|, respectively, which simultaneously extend the bolts I 5, l6, l1 and I8. The four doors are now locked.

In the locked position of the doors the bolts engage the brackets 51 of the window locking means. These brackets are moved into positions in which the arcuate pawls 53 of the window looking means engage the ratchet whee s 52. Then the windows may be closed but cannot be opened.

From the interior of the vehicle it is possible to open certain of the doors. This is accomplished by pulling the head 38 and then moving the spindle 32 upwards relative to the bar 21. This retracts the bolts l5 and I6. When the lock mechanism is thereafter operated to open the other two doors the bar 21 will move upwards and the collar 35 will snap into the recess 34 and now the parts are again in position in which the doors may be locked While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
