4 Claims.

This invention relates to door locks and the object of the invention is to provide a lock which may be used on the doors of automobiles, airplanes, boats, and analogous vehicles, or on the doors of buildings and the like.

A further object of the invention is to provide a door lock of the character mentioned which may be operated from either side of the door and which may be operated from the inside of the door for locking the door against being opened by an unauthorized person from the outside.

A further object of the invention is to provide a lock of the character above mentioned which, while the same may be locked from inside the door without resort to a key, a key will be required for unlocking the door from the outside thereof.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings Wherein:

Figure l is an elevational view of the complete lock assembly.

Figure 2 is an elevational view of the lock with cover plate removed and with the inner handle in a normal or unlocked position.

Figure 18 is a perspective view of the bolt.

Figure 19 is a perspective view of a horizontally slidable member hereinafter more fully referred to.

Figure 20 is a perspective view of a bracket hereinafter more fully referred to.

Referring to the drawings by reference numerals it will be seen that in the preferred embodiment thereof the door lock comprises a suitable casing l divided into a pair of compartments 2 and 3 respectively through the medium of a partition plate 4. Provided in the compartment 2 are upper and lower guide members 5 between which as clearly shown in Figures 2 and 7 is slidably mounted a locking bolt 6 that is normally urged to a projected position through the medium of a suitable spring device 1.

For the inside of the door lock is a handle 33 which as best shown in Figure '7 is secured to one end of a stud 3! journaled in a suitable bearing 32 provided therefor at the inner side of the easing l. The stud 3| has a squared end that extends into the compartment 2 and on said squared end there is provided a male head 30. Head 30 has suitably associated therewith a lug 38 which as shown in Figure 5 moves into engagement with a lug 42 on the bolt 6 incidental to a swinging movement of the handle 33 in a counter-clockwise direction for retracting the bolt 6 from the inside of the door with which the lock is associated.

Further in accordance with the present invention there is arranged for sliding movement in the compartment 3 a slide block 8 that is normally urged in one direction through the medium of a suitable spring device 9.

As clearly shown in Figure 6 slide block 8 has secured at one side thereof through the medium of bolts 2 an abutment block ii that operates within a channel l0 provided therefor in the bolt 6. V

In this connection it will be noted that the partition 4 is provided with a slot 4a to accommodate the bolts I2.

Mounted for vertical sliding movement in the compartment 2 is a slide plate l3 having a reduced lower end that works vertically through a slot l4 provided in the bolt 6 adjacent one end of the channel ID. The slide plate I3 is normally urged upwardly through the medium of a member l5 preferably of the shape and construction shown in Figure 16 and which member is provided with pintles l6 journaled in the apertured lugs ll of a bracket l8 suitably secured in the 7 ber l5 has a part thereof engaging in a notch 20 in the upper portion of the slide 3 as shown in Figures 10 and 11 for transmitting movement of the member l5 to the'slide l3.

In Figure 10 the member i3 is shown in its raised position and asshown in Figure 6 when the member I3 is in raised position it provides Thus whenthe' an abutment for the block ll. member 3 is in raised position it will be seen thata sliding movement of the block 8 towards the right in Figure 6 will cause the block H to :abut the member l3 'so that the movement of the block 8 in the direction indicated will be transferred to the bolt 6 for retracting the latter.

For moving the slide block 8 in the direction above referred to for retracting bolt 6 there is provided at the outer side of the door or lock casing a handle 23 that has an end portion pivoted as at 24 within a suitable recess R provided therefor in the outer wall of the lock casing I. At the pivoted end thereof the "handle 23 is provided with an integral projection or dog 25 which engages a notch 26 formed at one'end of the block 8. Thus it will be seen that with the slide l3 in its raised position an outward'swinging movement of the handle 23 to the position shown in Figure 6 will ina manner just explained result in a retraction of the bolt 6.

From the above it will be seen that through the medium of the handle 33 bolt 6 may be retracted from the inner side of the door and through the medium of the handle 23 bolt 6'may be retracted r from the outer side of the door.

For securing the bolt 6 against being'retracted by manipulation of the handle'23 there is pro vided on the male head30 a lug 31 which, when the handle 33 is swung from the position shown .inFigure'Z to the position shown in Figure 4, will engage an extension 35 of them'ember |5 for causingthe' member l5 to move downwardly thus causing the slide plate |3to move downwardly. In this connection, and as shown in Figure 4, it will'be noted that as the lug 31' engages the extension 35 of' member I5 forforcing the latter downwardly against the action of spring l9 lug 38 associated with the head'30m'oves upwardly into engagement between spring jaws 39 suitably mounted in compartment 2 for securing the bandle 33 in the position shown in Figure 4.

' When the'member i3 is caused to'move downwardly in the manner just mentioned the slot or notch Z'I-in'said member will align with the channel In so that the member l3 will now offer no Figure 2.

resistance to the block n. Thus with the mem-.

ber l3 in the lowered position it will be seen that handle 23 may be manipulated for sliding the 7 Also in accordance with the present invention there is suitably mounted on the outer cover plate of easing a key-controlled lock 21 which includes among other parts a key-operated bolt 28 that extends through partition 4 into the compartment 2. On the squared portion of the bolt 28 is a female head member 29 which receives in the socket portion thereof a part of the male head 30 as shown in Figure '7.

In connection with the above it will of course I be understood that member 29 rotates with the bolt 28 relative tothe head 30. Member 29is provided with an integral lug 4| as shown in Figures 2, 4 and 5. c a

It willthus be seen that when it is desired to set the look from the outer side of the door to prevent retraction'of the bolt 6 the key 4|lis inserted into the lock 21 and. the bolt 28 rotated in a clockwise direction; This will result of course in head 29 rotating with the bolt for movingzthe lug 4| associated with the head into engagement with the extended end 35 of the member l5. Thus lug 4| engaging said end 35 of member l5 will cause the latter to move downwardly against the action of spring l5 for placing the slide 3 in the position shown in'Figure 11.

As previously pointed out with the slide |3 in its lower position handle 23 may be manipulated for moving the slide 8 against the action of spring 9 without in any way effecting a retraction of the bolt 6. 1

For locking the parts shown in the position in Figure 5, and to which position they were moved incidental to a turning of the key 40 in the lock 21 as just described, there is suitably mounted in.

and associated parts in the position shown in With the head '29'locked in the position shown in Figure'5 member l5 will be held in the down- Ward position shown in'Figure 5 so that as just mentioned the assembly is locked in a manner to preclude an opening of the door, or in other words a retraction of the bolt 6 by manipulating the handle 23 at the outer side of the door. Obviously, to unlock the door from the outer side thereof key 48 is turned in a reverse direction, or in a counter-clockwise direction causing the head 29 to move in a corresponding direction from the position shown in Figure5 to the position shown in Figure 2 thus permitting the member l5 to move upwardly under action of spring l5 for raising the slide plate I3 so that the same will now present an abutment to the abutment block 'i l. Upon "return of head 29 to the position shown 75 in Figure 2, catch 43 will engage the socket 44a as shown in said Figure 2 for locking the head 29 in the position illustrated in said figure.

A bearing bracket 36 depends from the top of the compartment 2 and is provided with an opening 36 which accommodates the cylindrical part of the head 30 as shown in Figure '7. In one edge thereof the bracket 35 is provided with a notch 36a, for the purpose of allowing lug 31 clearance when the inner handle is used for retraction of bolt 6.

Since the manner in which the device operates was pointed out in the detailed description of the parts it is thought unnecessary to again set out in detail the operation. Suffice it to say that a lock constructed in accordance with the present invention may have the bolt thereof retracted from either the inner side or outer side of the door with which the lock is associated, or said bolt may be disconnected from the operating means therefor at either the inner side or outer side of the door to the end that a substantially fool-proof lock is provided.
