Be it known that I, z ILLIAM H. THOMAS, a citizen of the United States, residing at Whittier, in the county of Los Angeles and State of California, have'invented new and useful Improvements in Lock and Latch Mechanism, of whi h the following is a speci fication. This invention relates to alock in which a latch-bolt is operable by on or more door knobs and keys and a dead-:bolt is operableby a key accessible from one side of the door; and in which said key is operable through the .medium of a cylinder-lock by a key on the placein a door, the outside key being shown withdrawn. Fig. 4 is a detached perspective view of the inner key. Fig. 5 is a detached erspective viewlooking at the opposite en( of the key shown in Fig. 4.
. 1 designates an ordinary mortise lock case. 2 designates the barrel of a cylinder lock, the same being provided with tumblers 3 to "engage the cylinder 4 of the cylinder-lock.
' latch-bolt as well as the dead-bolt may'be locked at one and the same time, and in which a partialrotation of either of said keys will e.'"ect the unlocking of both of said bolts 3 rrovision being made whereby, whenever the dead-bolt is locked, the latch-bolt is also I locked. i
Objects of the invention are superior convenience and security with a. lock of comp aratively few and simple arts. l Other objects and adi antages may appear lock mechanism, and 6 a key loosely interlocking with the barrel 2 and arranged to opfrom the subjoined detailed descri tion. l erate said mortise lock mechanism, which In The invention com rises 21. loo 1 having the form shown comprises a latch-bolt 7, a alatchboltandadead olt that may unitedly dead-bolt 8, means, as a dog 81, to hold the 'lock a door and will res end to a single key" dead-bolt stationary anda tumbler 9 to operfor simultaneous witln rawal from locking ate the latch-bolt. The key 6 which interosition; and ironiwhich lock the key may looks with the barrel 2 is adapted to operate e withdrawn while the dead bolt is in either the tumbler 9 directly and said dead-bolt 8. the looking or unlocked position, and while 10 is a hub-lever for operating the latchact as a latch bolt for night or day locking, and to respondto the 3 faces 11 and 12. key; and in which the (leadbolt may remain '13 is a dog norm'allyheld by a s ring 14 in in unlocked position while the latch bolt is 1 position to engage the face 11 for ocking the being locked and unlocked by the key, and l hub-lever 10.
the key maybe turned sndlciently to unlock I 15 is the hub for operating thehub-lever the latch-bolt and for withdrawal through 10. The immediate means provided for rethe key-hole without disturbing the un 1 locked dead-bolt; or may be turned fully around in the same direction, thereby throwl mg the dead-bolt into locking position, and l l vidcd with arms 17.
'Ihe tumbler 9 is provided witha face 18 to release the dog 13, and with a face19'1'or directly operating the hub-lever-10-whenever the key 6 is rotated to unlock the dead-bolt S. The block 16 is adapted to be rotated by knobs 20 and 21 mounted on an angular may be withdrawn; and in whi h, when the dead-bolt. is fully thrown into locking posi- 1 tion the latch-bolt will bepositivcly locked against withdrawal from its latching position 5 ima general way indicates the mortisebolt 7, the same being provided with two tating the hub comprises a block 16 procated by :c' -a: Fig. 1, showing the lock in seats 27 and 28 of the escutcheon plates 29 and 30 respectively. Said knobs are provided with angular seats 31 and 32 for rotating the angular spindle 22 which projects therethrough. 33 and 34 designate shouldered sleeves on the angular s indle 22 and which are secured into screw-t readed- sockets 35 and 36 of said knobs.
37 is a cylindrical seatin the hub 15 in which a flange 38 on the outer sleeve 33 retates, said sleeve being held in place in the hub by an ofi'set or shoulder. 39.
The block 16 is seated in the hub 15 and is adapted to rotate the hub by means of the arms 17 seated in the-hub at 37. The spindie 22 rotates the hub through means of the block 16 which has an angular perforation 40 through which the spindle extends.
The inner key 6 has a stem 41 extending through acap 42 of the cylinder that is screwed onto a portion 43 of the main body 44 of the cylinder 4 of the lock, andis rovided on the end with a knob 45 fastened by a screw 46. Said inner key is provided with .an enlarged base 47 mounted in a bearing 7) inthe cylinder and having two slots 48 and 49 which respectively accommodate two pins 50 and 51 in the endof the barrel 2. Those slots are semicircular and the pins 50 and-'31 serve to communicate the rotation of the barrel 2 to the key 6 whenever said barrel is sufficiently rotated by the outside key 53; and the arrangement of the slots and pins is such that a complete revolution of the barrel may be had in the operation of turning the web 54 of the key from one stop 55 to the other sto 56, that limit the inner key 6 to a half-revo ution. j'
57 is a spring between the cap 42 and the shoulder 58 of the inner key-stem to hold the inner key resiliently pressed against the end of the barrel.
In practical use, the inner key may be retated by the knob 45, therebythrowing the tumbler 9 which thereupon lirst engages the dog13 and starts it from the path of the hublever, and then while the dog is thus being moved out of the way of the hub-lever the tumbler engages the hub-lever to draw back the latch-bolt 7. At the same time the web of the key withr'traws the dead-bolt S, which 640 in its locked position is held by the tumbler 9 in the usual manner, but is released when said tumbler 9 is moved by the web olthe inner koy in the unlocking operation. By the construction shown, the hub, the latch-bolt .eit er'direction.
and the dead-bolt are all simultaneously unlocked, thus releasing the knobs on the half rotation of the inner key. The dead-bolt is provided with a rearward extension 59 that engages the dog 13 and holds it out offthe.
is drawn.
Whenever the dead-bolt 8 is in locked po sition, the do; 13 is held by the spring 14 in position to lock the hub-lever 10, and con se uently the knobs can not be turned in VVl'ienever the dead-bolt is unlocked, the latch-bolt can be withdrawn by simply turning the knobs. When the lock is operated by the key 53,
one complete continuous revolution of the barrel in one direction will turn the Web of the key hall a revolution, thus simultaneously either looking or unlocking the deadbolt, latch-bolt, and hub, and consequently the knobs, thus allowing the key to be removed ,l'rom the barrel whether the door is locked or unlocked, and leaving the barrel in the same position in bothconditions ol' the lock. i
Referring to Fig. 2 it will be noted that the dead-bolt is in unlocked position and'the latch-bolt is in locking position, and that the web 54 of the key is in such position that it may be turnedupward to, the left in the direction of the arrow thereon, and will, when so turned, first engage the tumbler 9 and move it on its pivot 60 and swing it upward in the direction of the arrow thereon, thus moving the hub-lever l0 and the hitch-bolt draw the latch bolt, and also to allow the key to be withdrawn from the key-holc-(il without disturbing the dead bolt. The full movement for withdrawing the latch-bolt is accomplished in about one-eighth of a turn.
of the key-web 54, thus allowing the door to be opened, whereupon the key 53 may be brought into line with its key-hole 61 in the barrel and withdrawn from the lock. l, in stead of withdrawing the key at this juncture, the key is rotated a full revolution, it will, at the, close of such revolution again keyhole. 61 buttgyill leave both ofthebolts in locked position sinwn in Fig. 1.
