IDGOR-ZOCEZ MECHANISM.

Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed March 11, 1918. Serial No. 221,662.

To all whom it may concern:

oeit known that l, FR-iNK F. Snrrrrr, a citizen of the United Stat s, and a resident of the city of Newark, in the county. of Essex, State of New Jersey, have invented certain new and useful Improvements in Door-Lock Mechanism, of which the following is a specification.

The improvements relate to locking devices of the emergency exit or ionic lock variety and have for their objects, among others, the provision of simple a1 d effective means for automatically dogging or blocking the belt which engages the socket-plate, and holds the bar, and any other bolts if other bolts are connectedtherewithin un locked position while the door is open. This provision is very desirable where there a flush sill or a 'carpeted floor, as by holding the bolts in retracted position when the door is swinging injury to the sill, floor or floor covering is avoided, as well as injury to the bolts themselves.

The improvements are illustrated in the accompanying drawings, in which Figure 1 is an elevation of an automatic dogging device with the adjacent socket plate in vertical section; Fig. 2 is an inside edge view of the some removed from the face of the door; Fig. 8 is a view from the edge or side opposite that of Fig. 2;. Fig. is a vertical section of the housing substantially on the line 4-4- of Fig. 2, with the parts contained in said housing shown in elevation, and in a different position from that of Figs. 1 and 2; Fig. 5 is a detail of the bolt in side elevation; Fig. 6 is an edge view of the bolt detached; Fig. 7 is a detail of the tripping lever for releasing the dogging device with the pins for which it is mounted in the housing and connected with the adjacent cooperating member.

The rod A, in the illustration of the invention shown in the drawings, is mounted to move up and down, and to retract the bolt or bolts connected therewith on its upward movement. The downward and-locking movement being caused wholly. or partly by the gravity of the said rod. This general construction is shown and described in my Patent No. 1,117,457, of November 17 191%. The rod may be moved upwardly by means of a panic bar, such as that shown in, the said patent or any other suitable means' A sleeve C receives the threaded upper end of therod A and connects it with the rod in, to which the said sleeve is joined, the rod E extending upwardly therefrom into the housing H and connecting with the bolt B.

The upper end of the rod E is connected with the bolt B by means of the link consisting of the medial part L, the lower forks F spanning the reduced part E of the rod, and the upper forks G similarly arranged withrespect to the lower end of the bolt. The forks F are pivotally connected with the upper end of the rod at E and witi the tail B of the bolt at J, the pivot 5 be ing out of alinement vertically and insice the pivot K of the bolt, so that the upward tirust of the rod communicated to the tail of the bolt through the link will cause the said bolt to rock on its pivot and withdraw its nose from the socket M. Movement of the rod in the opposite direction, will, therefore, cause the bolt to look. In this .inanner a ver sim le stron and ,ositivo connection between the vertically operating rod and the bolt is provided. The rod E extends through an opening H in the bottom of the housing H, and is held against lateral movement in the direction of the door by the pin N extending through said housing.

If the bolt were not provided with the automatic dogging means it would return to its locking position as soon as the rod A was released and allowed to fall, and as this usually occurs during the opening movement of the door upper and lower bolts controlled by the rod would project therefrom upwardly and downwardly and strike anything in their path, to the injury of floors, floor coverings, and other parts, if not to the bolts, as hcreinbefore noted. The rocking dog D is therefore provided for the purpose of detaining the bolt and holding it in its restricted position during the opening and closing movement of the door, and this also holds the rod A and any other bolts that may be connected therewith in unlocked position. The dog or detent D is pivoted by means of a pivot pin 0 extending therethrough and secured at its ends in the housing, and the portion of this member nornally below its pivot is made of greater thickness and weight than the upper part, so that when released it moves by gravity to the position shown in Fig. 4:. When the door is closed, however, it is held out of this position by the lever B pivotally connectcd with the dog D at P and pressed inwardly by contact of its enlarged upper end with the strike plate S depending from the socket plate.

The lever B oscillates on the pivot T by which it is mounted on the outside of the housing, and the pin P is secured to its lower end, extends through an opening in the housing and through the upper end of the dog D. When the door is closed therefore and the upper enlarged end of the lever B is pressed inwardly, the upper end of the dog is movedin the opposite direction and its lower weighted end raised. The devices remain in this position while the door is closed. When the door is opened, however, the pressure on the upper end of the lever It is immediately released, and the weight of the lower end of the dog throws its upper end into the path of the pointed eX- tremity of the bolt tail B, so that the bolt and the rod connected therewith cannot re turn to locking position. When the door reaches its closed position, however, the up per end of the lever B is again thrown back by contact with the strike-plate S and the detent extremity of the dog D d awn out from under the tail B so that the bolt is incidentally shot and the door locked.

What I claim is:

l. The combination of abolt, a pivot on which said bolt is mounted intermediate its ends, said bolt comprising a locking portion on one side of the pivot adapted to move into and out of locking position when the bolt is oscillated and a tail portion on the other side of the pivot, a rod mounted to reciprocate substantially in alinement with said locking portion and normally held by its gravity in bolt locking position, and a connecting member between said rod and said tail portion and positively secured to both whereby lengthwise movement of the rod imparts movement to the bolt in substantially the opposite direction, the arrangement being such that when the rod moves toward the pivot the locking portion of the bolt moves toward the rod and from its locking position, and when the rod moves away from the pivot the locking portion of the bolt moves away from the rod and to its locking position.

2. The combination of a bolt, a pivot on which said bolt is mounted intermediateits ends, said bolt comprising a locking portion on one side of the pivot adapted to move into and out of locking position when the bolt is oscillated, and a tail portion on the other side of the pivot, a rod mounted to reciprocate and nor a ally held by its gravity in bolt locking position, and connection between said rod and said tail portion whereby lengthwise movement of the rod imparts movement to the bolt in substantially the opposite direction, the said connection between the rod and the bolt com"- prising a link pivoted and positively connected to the rod and to the tail portion of the bolt, and arranged to move on lines angular to the movement of both rod and bolt.
