LOCK.
Specification of Letters Patent.
Application filed March 5, 1908.
Patented Apr. 12, 1910. Serial No. 419,303.
To all whom it may concern:
Be it known that I, Timmer F. DIESEL, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Locks, of' which the following is a specification.
This invention relates to locks, and consists in the mechanism hereinafter described and claimed.
The object of the invention is to provide a deadlock in which the bolt is always fastened when in the locking position, but which nevertheless is released when the bolt comes into contact with the striker and thus permits the device to lock. Incident to this eifect, the specific construction is capable of being opened from one side either by a key or by a hand-piece, or by both, and from the other side by a key.
Other features will appear in the course of the description.
In the drawings: Figure l is an elevation of a lock embodying this invention, with the cover plate removed, showing` the parts in the locking position; Fig. 2 is a like front elevation, showing the bolt in the raised position; Fig. 3 is a section on the line 3 3 of Fig. 1; and Fig. 4 is a vertical, central section through a portion of the latching lever or bolt.
The lock has a casing 1 and a cover plate 2 (Fig. 3). lVithin the casing is pivoted at 3 a hook, bolt, or latch 4. This hook or bolt is adapted to engage a striker plate 5 upon the jamb of the door. The striker plate may have a perforation 6 through which the head of the hook 4 passes when the latter is in the raised position shown in Fig. 2. Then the parts are in the locking position shown in Fig. 1, the hook or bolt 4 engages tlhe striker to prevent the opening of the c oor.
Within the casing is a dog 7 pivoted at 8,
which dog has an engaging part 9 having a face adapted to engage in a notch 10 in the bolt 4. The parts are so proportioned, and the pivots of the dog 7 and the bolt 4 are so located, that when the engaging part 9 of the dog is in engagement with the face of the notch 10 of the bolt, the bolt is locked and cannot be lifted. The pressure caused by turning the bolt around its pivot is resisted by the dog 7, and the pressure of the face of the notch 10 against the engaging part 9 of the dog is substantially directly toward the pivot 8 of said dog, so that, when the bolt is in its lowest po-sition, it cannot be moved until the dog is tilted out of the notch 10.
The bolt 4 has a disengaging means for the dog, which is made operative automatically by pressure of the free end of the bolt against the striker plate As usual, the bolt 4 has a curved or inclined face which, when the bolt is down and the lock moves toward the striker plate, automatically causes the bolt to rise and to slide over the engaging edge of the striker plate, so that when the door or gate that carries the lock is fully closed, the bolt may drop down automatically and latch to the striker plate.
In the example of the invention shown herein, a block or plate 11 projects from the inclined striking face 12 of the bolt. The block may have the same inclination as the inclined curve or edge 12, and moves in and out of a socket 13 in the bolt. Extending from the striker block 11 is a bar 14 that lies in a channel 15 therefor in the bolt. Mains, such as the screw 16, whose end rests in a'notch 17 in the bar 14, limits the motion of the bar in its channel. The said bar prof jects into the notch 10, and has an inclined end 18 of such an inclination to the face of the engaging part 9 of the dog 7 that when said bar is projected inward into the position shown in Fig. 4, said engaging part 9 slides easily upward on the said inclined face 18 and is freed from the normal face of the notch 10 by reason of the projection of the end of the bar into said notch.
A spring 19 within the casing 1 is employed to throw the dog 7 downward, and may be used to press the bolt 4 downward also, so that the one spring accomplishes the two purposes; This spring, in the example of the device shown, presses against the hand-piece 2O attached to the dog 7 and eX- posed through a suitable opening 21 in the casing or its cover, permits the dog to be tilted and disengaged from the bolt, so that the latter may be raised by hand. But in order that sutlicient tilting of the handpiece 2O may raise the bolt 4, the dog 7 has a downward extension 22 carrying a projection 23, which, when the dog is tilted, and as soon as the engaging part `9 is lifted out of the notch 10, comes into contact with the lower side of the bolt 4 and lifts it so as to release the latch from the striker plate 5. A lock 24 having a bolt 25 may be employed to lift the dog 7 and release the bolt, and then lift the bolt, by projecting the bolt 25 of the lock 24 from the position shown in dotted lines in Fig. l to that shown in dotted lines in Fig. 2. The key-lock 24 may have a key-hole on one, or on both sides of the lock casing.
The device is therefore a deadlatch, incapable of being disengaged and lifted by the insertion of a knife or blade of steel between the striker plate and the lock in a usual way. The bolt is locked down by the dog 7, and cannot be lifted except by tilting the dog 7 either by the hand-piece .2O or by the bolt 25 of the key-lock 24. But if the device should be upon a door or gate, and should be latched by the dog 7, nevertheless, upon closing the lock upon its striker plate, the bolt will not be broken, nor the parts damaged, because as soon as the block ll touches the striker plate, the bar 14 is projected inward, wedging the engaging part 9 of the dog` 7 out of the notch 10 by means of the angular face 18 upon said bar. Then, when the inclined or curved face l2 of the bolt strikes the edge of the striker plate, the bolt can tilt upward and pass through the aperture 6 in the striker plate, and then when it has passed through to the proper extent, it can drop down and latch to the said striker plate. v
It will be noticed that the pressure of the spring 19 forces the engaging part 9 of the dog 7 into the notch 10 when the bolt is in its lowered position, and that this pressure on the inclined face 18 of the bar 14 forces said bar outward and causes the block l1 to project from the end of the bolt 4, and thus the parts are restored to their original position.
Vhat I claim is:
l. In a lock, the combination of a pivoted latch, a pivoted dog for engaging and locking the latch, and means operated by contact of the latch with a. striker plate for automatically moving the dog to disengage it from the latch.
2. In a lock, the combination of a pivoted latch, a pivoted dog for engaging and locking the latch, and a wedge operated by contact of the latch with a striker plate for automatically moving the dog and disengaging it from the latch.
3. In a lock, the combination of a pivoted latch, a spring-actuated dog for engaging the latch and for pressing it toward and fastening it in its locked position, and means operated by the contact of the latch with a striker plate for automatically disengaging the dog from the latch.
4. In a lock, the combination of a pivoted latch, a pivoted dog which when moved in one direction locks the latch and when moved in the other direction releases and moves the latch, movable means operated by contact of the latch with a striker plate for automatically disengaging the dog from the latch, and means for further moving the dog to tilt and unlock the latch.
