7 Claims. (Cl. 70-149) This invention relates to a door lock and more particularly to a combined door lock and dovetail 1 for an automotive vehicle.

A combination dovetail and door lock is old and well-known. It is the object of this invention to improve upon this form of door look.

This invention contemplates a combined dovetail and lock which obviates the need for cutting into or recessing the door lock pillar and thus is adapted for use with a narrow door pillar.

It is also 'the object of this invention to produce a combined dovetail and lock of the narrow pillartypein which the outside door handle can be readily disconnected from-the latch bolt.

In the drawings: v

Fig. 1 is a. vertical section through the door pillar showing the combined dovetail and lock as sembled to the door pillar as viewed from outside the door.- a

Fig; 2 is a view similar to that shown in Fig. 1 with the outside rollback turned to bolt-retracting position but disconnected from the bolt.

Fig.3 is a section along the line 3.3 of Fig. 1.

Fig.6 is a detail of 'oneof'thelevers for operating the bolt.

backed up by a pair of coil springs l2 and a block of rubber I3.

Since the lock bolt I4 is vertically reciprocable, to this end the housing 8 'is provided with an insert Hi. This insert is provided with a groove I! which cooperates with the outer wall l8 of the housing to form a guideway for the bolt H. Thelower inclined face ID of the socket member is provided with an opening through which the bolt l4 projects for interengagement with the wedge member 4. The wedge memberl is provided with a pair of notches l9 in which the bolt l4 interengages the wedge member 4. Thus the wedge.

by means of a lever 20 which is pivotally mounted on the insert 15 by the pin'2l. The lever 20.en.- gagesthe bolt in the notch 22. The inner end 23 of the lever 29 pivotally engages a bell crank lever 24 in the notch 25. The bell crank lever 24 is pivoted on the latch frame 5 by the pin and is pivotally connected to a draft link 21. When the draft link 21 is drawn to the left, Fig. 8; the bell crank 24 rotates clockwise and thus swings the lever 20 counterclockwise, as viewed in Fig. 5,

Fig. 7 is ahorizontal sectionthrough. adjacent door and body pillars with the door closed and latched.

Fig. 8-is an inside elevation of. the lock showing Fig. 9 is a detail view ofthe key o erated c'ylinder lock and connections for locking and; unlocking the look from without the door.

Referring more particularly to the drawings there is shownan automobile door I and a body jamb pillar 3. The door lock pillar is referenced natedt-liand retracts the bolt l4 into the housing 8 to disengage the bolt from the keeper 4.

When the draft "link 21 is released,the'bolt. is projected by the spring '28 acting through levers 29 and 20. The lever 29 is pivoted to the outer flange 80 of the latch frame 5 by pin 30 and engages the outer end 3| of the lever 20 in the notch 32. One end of the spring 28 is connected to the lever 29 and tends to rotatethe same counteri clockwise, Fig. 1, and the other end of the spring 28 is secured toa lug 33 on the latch frame 5.

- The lock which is fixed to the door. pillar 2 v comprises a. frame 5 of horizontal Usection which circumvents the side vertical edge of the window 1 glass panel 5. When the door! isclosed, the I wedge member 40f the dovetail. member-is rev ceived in .thedovetail socket --gener.ally-- desig- The dovetail socket comprises a housing in the form of a stamping 8 which is. secured by bolts 9 to-the'outside face of the door, pillar 2.. The 1 upper face:.of the dovetail is provided with a yildable shoe ll carried within the housing 8 and The outside rollback 34 is rotatably mounted upon' thelatch frame 5.1 The inner end of the link 31., and levers--29 and 2lljto retract the-latch boltll. "Thelever 36- is alsopivotally mounted on the outer flange .80 of the latch frame by pin and has a.lug ,38 whichpasses through a; slot 39 in the outer flange of the. frame 5 and engages the rollback 34. The lever-36 is held against the rollback 34'. by the spring 40, one endof which is secured .to thelatch frame 5 and the other end is secured to the lever36 lever36 also. carries the link 31 which is pivotally connected to the -.The lever 291s slot 42 which forms notches 43 and 44 in the lever 23.

The link 3'l is provided with a pin 45 which outside handle 35 is ineffective to retract the bolt M, then the link 31 is shifted to the right, Fig. 1, so that pin 45 is disengaged from. notch 43 and free to swing into notch 44. At this time if the outside handle is turned to swing the lever- 35 clockwise, Fig. 1, to raise the link 31', the pin 45 merely idles in opening 42, i. e., travels upwardly into notch 44 without swinging the lever 29. The swinging clockwise rotation of the lever 36 is limited by the lug 38 engaging the righthand end of the opening 39 in the latch frame 5, see Fig. 2, so that when the pin 45 is disengaged from notch 43 the swinging of the lever 36 within the limits permitted by slot 33 causes pin 45 to idle or travel in the opening 42 into and out of notch 44 without swinging lever 29.

Pin 45 can be shifted in the opening 42 into and out of notch 43 from the outside by the bell crank lever 45. The bell crank lever 48 is pivoted to the latch frame by pin 41. One arm of the lever 45 is provided with a notch 43 which re-. ceives the pin 45. The other arm of the lever is notched as at 49 for receiving the eccentric lug 50 carried'by a conventional cylinder lock II. when the key 52 in the cylinder lock is turned. the eccentric lug 53 acts through the lever 45 to swing the pin 45 into or out of the notch 43. The lever 43 can be operated from within the vehicle by bell crank 53 acting through lever 54. Bell crank 53 is pivotally mounted on the inside flange of the lock frame by the pin 55 and is provided with a notch 53 for the inner end 51 of lever 54. The outer end 8101 lever 54 isreceived in notch 53 in the lever 45. The lever 54 is pivoted to the insert II by pin 30. Over center spring 3| has one end 32 fixed to the lever 54 and the other end 33 fixed in the insert so that the over center spring 3| tends to hold the lever 54 at all times to one or the other side of its pivot 33. In other words, when the draft link 34 is pushed to the right (Pig. 8. dotted line showing) to swing the bell crank 33 clockwise. the lever 54 is swung counterclockwise-Fig. 5, which swings lever 43 clockwise. Pig. 1, to disengage pin 45 from notch 43. This makes the outside handle ineffective to retract the latch bolt.

Whenever the door is swungshut the latch bolt I4 is retracted by the keeper 4 before it is projected into the keeper openings ii. If the lever 43 has been swung either from the outside or the inside of the'door todisensase pin 45 from notch 43, closing of the door will automatically reconnect the outside door handle with the latch bolt. This automatic reconnecting of the outside door handle with the latch bolt is accomplished by the cam edge 33 of'the opening 42 in lever 23.

lever 53 can be swung clockwise to the dotted line position of Fig. 8 which acts through levers 54 and 46 to shift the pin to the full line position shown in Fig. 2, that is, out of engagement with notch 43. The outside handle is now disconnected from the latch bolt, that is, the outside handle is ineffective to retract the bolt. While the door is still open, the outside handle can be turned to bolt retracting position which. as shown in Fig. 2, swings lever 35 clockwise and raises link 31 so that pin 45 is drawn into notch,

44. While still holding the outside. handle in bolt retracting position, the door is closed. In the closing of the door, the keeper retracts bolt l4 which through lever 20 raises lever 23 to the dotted line position shown in Fig. 2, but since pin 45 is raised into notch 44 the cam edge 33 does not reach pin 45 andthus pin 45 remains in notch 44 and is not shifted to the left. After the door is closed. the handle is released and pin 45 swings downwardly out .of notch 44 but to the right of notch 43. Thus, the outside handle remains disconnected from, and ineffective to retract, the. latch bolt.

From the above it is seen that when the door is closed the outside handle can be disconnected from the latch bolt either from the outside of the door by turning the key 52 or from the inside of the door by swinging of lever 53. The door can also be locked from without without the use of the key as above'described. Unlocking of the door can be accomplished from without only by means of the key 32 and from within by swinging oflever 53 from the dotted to the full line position, Fig. 8. The lower end of the bolt i4 is notched out as at 33 to, provide a clearance for the lever 34 when the bolt is retracted,
