Specification of Letters Patent. v Patented July 16, 1918.
Application filed March 28, 1918. v Serial No. 225,202.
To all whom t mag/concern.'
Be it known that I, HENRY H. CRANE, a citizen of the United States, whose residence and post-oiice address is Floral Park, Long Island, in the State of New York, have invented certain new and useful Improvements in 'Loc-ks, of which the following is a specification, reference being had to the accompanying drawing, forming apart hereof.
This invention relates to locks of the tyy e generally known as dead locks, in which the bolt is thrown from the inside of the door by a lknob and is thrown from the outside of the door by a key. In such a lock the bolt is formed with the usual gate and gate posts on one side for cooperation with the cam or dog operated by the knob and on vthe other side with gate posts for cooperation with the camV or dog operated by the key. In the use of such locks it is possible and it sometimes happens that-the bolt is thrown only part way by the operation of the knob, from the inside of the door. kWhen this happens it is generally impossible to throw the bolt in either direction by means ofthe key from the outside of the door. It is then necessary either to call the attention of some one within the house, to complete the movement of the bolt, or to secure the assistance of a. locksmith. The object of thisinvention is to improve the construction of the lock so that the bolt can be thrown by thekey forward to its full extent and then thrown back or withdrawn, whereby the jamn'ling Gf the lock, so that it cannot be operated by the key, becomes impossible. To accomplish this result the bolt is provided with a supplemental gate post which is placed on the same side of the bolt with the gate posts for cooperationwith the cam 0r dog operated by the key, but substantially opposite the main gate posts, with respect to the axis of rotation of the key and knob, and, while not interfering in any manner with the normal operation of the lock, can be engaged by the key-operated cam or dog to throw the bolt Vcompletely forward from an intermediate position, when the same cam or dog can then engage one of the mai-n gate posts to throw the bolt back. The invention will be more fully explained. hereinafter with reference to the accompanying drawing in which it is illustrated, and in which- Figure 1 is a view of the lock in elevation, with the cap plate removed, showing the bolt thrown forward to the full extent, with the i key-operated cam or dog, shown by broken lines, in position to withdraw the bolt.
Fig; 8 is a similar view showing the bolt withdrawn by the key-operated cam or dog.
Fig. et is a view in section on the plane indicated by the line 4 4 of Fig. I, looking in the'direction of the arrows.
F ig. 5 is a view in elevation of'the cap plate.
Except as hereinafter indicated the lock may be of ordinaryconstruction. As shown in the drawings, the casinge receives the bolt Z2 and .the tumbler c in the usual manner. In the wall of the casing is mounted rotatably, in the usual manner, the knob-operated double cam. or dog cl, lwhichY cooperates, in the usual manner, with the gate Z2 and the gate posts b2 formed on the corresponding side of the bolt, the cam or dog also cooperating with the tumbler n the usual manner, as shown in Fig. 1, to disengage it from the stop a, on the casing, with which it coperates in the'usual manner. A cap plate e, adapted to be secured to the casing by a screw at e, e2, supports rotatably, in the usual manner, a key-operated bushing f and cam or dog f', which is shown in full lines' in Fig. 4 and by broken lines in the other figures of the drawing. The keyoperated cam or dog cooperates with the usual gate-posts 3 on the corresponding side of the bolt in the usual manner.
It is always possible and sometimes happens that, through inadvertence or accident, the bolt Z1 is thrown only part way by the knob-operated cam or dog d, as shown in Fig. l. If the key-operated cam or dog 7 be then moved in an anti-clockwise direction, it would strike upward against the lower edge of the right hand post b3 and would fail to move the bolt forward.
Similarly, if the supplemental gate post,
hereinafter' referred to, were not provided and the key-operated cam should be moved in a clockwise direction, it would strike upward against the lower edge of the left hand gate post b3 and would fail to throw the bolt back, The lock would then be vso Y jainmedand the bolt could not be thrown in Y either direction by the key-operated cam or the bolt is provided, on the saine side with the usual gate posts b3, but opposite theV` posts b3 (with respect to the axis of the knob and key bushing) with a supplemental gate post b4. Then, when the bolt has been left by the knob in the position shown in Fig. 1, the key-operated cam or dog f can be turned. in a clockwise direction. It will first make contact with the supplemental gate post b4 and will throw the bolt forward to the full extent, as represented in Fig.v 2. The continued movement of the key-operated cam or dog, in a clockwise direction, will then engage the tumbler c anddisengage it from the stop a and will then engage the right hand gate post b3 and will throw the bolt back from this rearlock be jammed in the manner described so that the bolt cannot be Operated by the'key. t will be obvious that the invention can be appliedl to locks of particular designs other than that shown inthe drawing and that the invention, exceptas pointed out in Vthe accompanying claims,-is not'limited in its application to the particular lock shown and described herein.V Y
I claim as my invention i '1. In a lock, the combination of a casing, a knob-operatedrcam or dog on one side of the easing, a key-operated cam or dog on the otherv side of the casingv and a bolt adapted for coperation with the knob-operated cam and provided 0n one side with posts for coperation with the key-operated the other side for normal coperation withV the key-operated cam ,and with a supplemental gate'post on the same side but opposite the usual gate posts, for coperation with the key-operated cam in throwing the bolt forward from an intermediate position.
