plane below the My Invention relates to improvements in showing the dogging device and lock and latch mechanism, and particularly for use on hinged or swinging doors.
The object of the invention is to provide a simple and effective means for automatically dogging the latch-bolt when the door is closed, so as to prevent retraction by means' of an instrument inserted at the edge of the door from the outside. In mechanisms of this general character it is by means of a key.
I have shown-my invention mechanism in which the same bolt serves as a latch-bolt and as a locking-bolt, being operable under normal conditions by either the inside or outside knob. The lock may be set so as to block the outside knob by suitn able means. When the outside knob is blocked, the bolt may be retracted by the use of a key Inserted from the outside. In embodiment of the invention as shown in the accompanying sheet oi drawings the latch-bolt is of the pivoted or swine"- ing type and adapted to be retracted by as applied to a adapted to swing a member which is retracted by contact with the striker-plate. The latch-bolt may, however, at this time be retracted inV proper manner by the operation of the knobs or key, the movement of the latch-slide itself serving to retract the dog so as to first free the latch-bolt. It will be obvious, however, that the invention 1s applicable to other types of locks and that the details of construction may be varied without departing from the spirit or scope of my inven- Figure 1 is a front view of a lock or latch pin carried by understanding of my invention. Fig. 3 is a IOO which is an integral part of the operating member 20.
21 is a spring normally holding the operator 20 in its extended position.
The outer end of the operator 2() is shaped substantially the same as the latch-bolt 6 and projects through an opening in the end plate 5, being limited in its outward movement by the shoulder 22 striking against'the back of the end plate. When the door is closed, the latch-bolt springs out into the pocket in the striker-plate and the operator 20is moved back by the surface of the strikerplate and held there. operator 2O permits the dog 7 to tilt under the influence of the spring 17, the pin or projection The parts then Fig. 4, the outer end of the dog standing back of the projection 11 on the latch-bolt. The projection 23, carried by the dog 7 on the side opposite pin 18, is held against an inclined shoulder 24, carried by the latch-slide, by the tension of the spring 17 when the operator 20 is retractedz When it is desired to open the door in the proper manner, the latch-slide is retracted and moves the pin 23 'up the incline 24, so as to swing the dog 7 and i'ree the projection 11. When the door is closed, the end of the dog 7 in position shown in Fig. 4 is separated a slight distance from the projection 11. The result is that the removes the dog 7 projection 11 have reached the dogging position of the dog. Continued retraction of the slidey then retracts the latch-bolt freely. The operation of the dog will therefore be seen to be automatic upon closing the door and effectively prevents the latch-bolt from being tampered with by an instrument inserted at the edge of the door.
The bolt 6 and operator 2O are both pivoted on the pin 8, which is threaded near its outer end and screwed into the end plate 5, so as to be removable. The bolt-spring 9 and the operator-spring 21 are both mounted on pin 25, and the dog-spring 17 is also connected to the saine pin. The axes of the pivot- pins 8 and 16 and spring-carrying pin 25, dog- pins 18 and 23, bolt-pin 10, and yoke-pivot 14 are all parallel to each other and to the planes of the side plate 4 and end plate 5. rIhis construction facilitates manufacture of the parts, assembling7 and operation. When the door to which the mechanism is attached is in the act of closing, the bolt 6 and dog-operator 2() both contact with the striker-plate at the same time. The operating-face of the cam 19 is so constructed, however, that the dog 7 is not immediately released or permitted to move to its dogging position. This lag in the movement of the dog permits the bolt projection 11 to intercept the dog, so that the bolt lmay move in- The retraction of the 18 being released from the cam take the position shown in ently thereof, a tracting movement of the latch slide 12 i before the latch-bolt 6 and ing a cam-face ward freely by reason of its contact with the striker-plate. As the closing movement continues the dog is released by the operator and thrown against the side of the bolt projection 11 by action of the spring 17. It rests against the projection 11 until the bolt is allowed to shoot out again, at which time the do@ being unrestrained by the operator or bolt moves into its dogging position, with its pin 23 resting against the slide-shoulder 24 ready for retraction by operation of the slide either through the medium of one of the knobs or the usual key.
