Specification forming part of Letters Patent No. 1S '7 5l, dated, January 1, 1878; application filed To all'whom it may 00mm.-
Be it known that I, SOLOMONOPPENHnnuclare that the following is a full, clear, and exaotdescription thereof, reference being had to the accompanying drawings, making a part or cap removed," and 'Fig. 2 is a perspective view of the same, both views showing. all the parts of the latch and lock in detail.
-'- Letters oflike name and kind refer to like parts in each of the -figures. v I
The design of my inventionisto produce a "door lock and latch that may with equal facility be applied to a door opening either to the,
right or left, easily operated, and-in which the locking-bolt cannot be forced backward by a key or any other instrument from the outside of the door; and it consists, principally, in the means employed to render the latch'reversible, substantially'as and for the purpose-hereinafter shown and set forth.
It consists, further, in the means employed for securing the latch and arbor in such a position that they cannot be moved except by a person inside the door, substantiallyas and for the purpose hereinafter shown and described.
It consists, finally, in the means provided for combining the latch-bolt and locking-bolt in such a manner as to form a double locking arrangement, substantially as and for the purpose hereinafter. shown, described, and set forth.
In the annexed drawings, A represents a knob or latch bolt, the projecting or outer end of which is shaped in theusualmanner. Upon the inner end of said knob or latch bolt A are I provided two lugs or ears, a and a, which, to-
gether with the shank of the former, form a T- head, which serves as a means of connecting 'it with and attaching it to the follower or slid- December 3,1877.
nishthe means for connecting the knob-or latch bolt A with the follower or sliding-plate B. The shank and lugs or ears 1 and a that form the T-piece upon the inner end of the knob or latch bolt A are constructed central with the body or outer end of the same, and by this means the latch-bolt is enabled to-be reversed, and applied to doors opening either to the right or left.
with a yoke, to and upon the ends of which are fastened and secured two posts, b and b, the office of whichlatter is, in connection with the arms of the arbor (J, to afl'ord themeans whereby the knob orlatch bolt A may be. operated by the knob. 1 y o i In order to increase the efficiency of the lock and add to its security adog, D,has been provided, which is firmly secured in position by being pivoted to the post D in such a manner as to enable it to beswiveled upon said postJ 'Upon the inner end of said dog, there is provided a clamp or pair of jaws of sufficient width to enable the same toclasp one arm of the arbor O and one of the posts 1;, and upon the outer end, and proj ecting through the rim of the lock, is formed a short handle, by means of which latter the dog D is thrown into or out of engagement with the arm of the arbor (l and post I) of the yoke.
The dog D is maintained in positionwhen either on or off by means of a brake, d, which consists of an oblong flame and a cylinder combined. The cylinder contains a coil-spring within it, by means of which latter the brake d is constantlyforced against the dog D. For the purpose of securing the brake d in position, and the correct operation of the spring, a backing post or pin, 01, is provided, and the cylinder is grooved vertically to correspond with said pin, and longitudinally to correspond with the length of the coil-spring;
By this arrangement it will be seen that when the brake is in position the oblong frame encircles the center-post of the lock, and the groove of the cylinder impinges upon the backing post or pin 01, thus insuring the action of the brake.
y The latch-boltAisthrown outwardby means of a lever, E,the lower end of which is pivoted to and upon a post, E, and which receives its The follower or sliding plate B isprovided' l pressure from a flat spring, 6, impinging upon a cam, e, that is formed'upon the hub or lower end of said lever. Recesses F and F are formed in opposite sides of the latch A, for the reception of the upper end of the lever E, and the latter, impinging upon the forward wall of the lower recess, tends to throw the latch A outward, The lever E is provided at its lower endwith a pawl, F, the office of which is, in connection with a lug, f, that is provided upon the upper side of the lockingbolt G, to form such a complete obstruction as shall prevent the locking-bolt from being ible latch is completed, and its operation is as follows: When it is desired to lock the dOor the locking-bolt G is thrown forward by means of the key, in the usual manner, and the lug f at the same time passes underthe pawl F1. When the locking-bolthas been thrownforward sufficiently far the pawl F drops behind the lug f, and thus the locking-bolt is firmly held in position by means of said pawl and lug, and, as will be seen, no key or other instrument will avail or can be made to throw or unlock the bolt from the outside without first turning theknob, and bythis means throwing the pawl F out of engagement with the lug f, and this is effectually prevented by throwing the dog D; on, as is clearly shown in Fig. 1. To unlock the door the dog D is thrown off, the knob turned, throwing the latch-bolt inward, and, while held in this position, the key will perform its properfunction and throw the locking-bolt G inward.
It will be seen that this arrangement not only forms a perfect dead-lock, but a double lock, because, as it is impossible to turn the knob from the outside after the door has been locked and the dog thrown on, the knob latch or bolt oifers just as much resistance as the locking-bolt does.
It is believed that this lock possesses the advantages of security, simplicity, and durability, and that the reversible latch will be appreciated by users.
Having thus fully set forth the nature and merits of myinvention, what'I claim'as new is-- 1. In combination with the reversible latch or knob bolt A, the upright post B, provided with the overhanging cap and placed upon the follower or sliding plate B, and the pins 1) and b,'arranged and constructed substantially as and for the purpose shown and described;
2. The dog D in combination with the arm 0 of'the arbor (5 and the yoke'of the follower or sliding plate B, whereby the arbor and yoke are held together and prevented from moving, substantially as and for the purpose shown and described.
3. The pawl F upon the lever E, in combination with the lugf upon the locking-bolt G and the latch-bolt A, whereby the locking-bolt is prevented from being forced, inward until the latch-bolt is withdrawn, substantially as and for the purpose shown and'described.
