To all whom it may concern Be it known that I, RUssnLL S. GOLD, a citizen of the United States, residing at New Britain, Hartford county, Connecticut, have invented certain new and useful Improvements in Panic-Bolt Mechanism, of which the following is a full, clear, and exact description.

This invention relates to panic bolt mechanism and is designed primarily to provide a panic bolt of very simple construction which operates on the gravity principle and which, in addition to numerous structural advantages, is provided with an automatic latching and retaining device, all of which will be seen from the detailed specification fol.- lowing.

In the accompanying drawings forming part of this specification, Figure 1 is a fragmentary view in front elevation of a door equipped with the panic bolt mechanism of the present invention, the view being a section on the line 1-1 of Fig. 2. Fig. 2 is a view in edge elevation of the parts shown in Fig. 1, the door being closed and latched. Fig. 3 is a similar view, but with the bolt retracted from locked position and with the door partially open, the panic bolt being held in retracted position by the automatic Figs l to 11 inclusive illustrate enlarged details of the bolt mechanism.

Referring to the drawings by numerals, 1 designates the usual swinging door, upon the inner face of which the panic bolt mechanism is mounted. Seated in the floor adjacent the edge of the door in closed position, is a flush plate 2, having an upwardly projecting stop member 3 arranged to engage the inner face of the door when the latter is in fully closed position. The door is preferably provided at this point with a strike plate shown at 4. The door casing at the inner side of the door has secured thereto and depending therefrom, an angular bracket plate comprising the base portion 5 extending horizontally and secured to the face of the door casing, and the vertical depending latch plate 6 having a latch aperture 6 therein designed to receive and hold a hooked bolt end. Extending transversely of the door is an operating bar 7 having its ends inturned at 8 and provided with short stub shafts or pivot pins 9, which journal into outwardly extending arms 10 of bracket plates 11 secured to the door by appropriate means.

PANIC-BOLT MECHANISM.

Application filed July 3, 1914. Serial No. 848,719.

Extending vertically of the door adjacent its swinging edge is a gravity actuated bar or rod 12, preferably in the form of heavy metal tubing. Intermediate its ends this bar is provided with an enlarged central portion 13 having a recess 14 therethrough providing spaced and oppositely disposed V- shaped abutment surfaces 14 This recessed portion is designed to receive an actuatlng arm carried by and operated from the cross bar 7, as will be hereinafter pointed out. The bar 12 is guided for vertical move ment and is positioned to extend across the face of the outermost bracket plate 11 with its enlarged portion 13 positioned over said bracket plate. The inturned end 8 of the cross bar which coperates with this specific bracket plate, is provided with an actuating arm 15 shaped to extend into the slotted portion 14: of the bar 12, and to engage the opposite parallel faces of the ahutments 1%. The normal position of this actuating arm and cross bar with reference to the gravity bar is indicated in Figs. 1 and 2 of the drawings, from which it will be seen that the crossbar is normally held outwardly by the weight of the gravity bar. This gravity bar provides the bolt portion of the panic bolt mechanism. It is guided for vertical movement by a plurality of brackets, two being shown in the drawings. One of these brackets, in the present instance the lower bracket, shown at 16, is provided with the guiding bore through which the lower end of the bar 12 extends. The gravity bar at this point is provided with a vertically extending slot 17 (Fig, 3) and the bracket 16 is provided with a pin 18 extending into the slot and preventing turning movement of the gravity bar while permittingvertical movement. The upper end of the gravity bar has so cured thereto a head 19 having a transverse hooked portion 20 projecting therefrom. The lugs 21 are also carried by the body 19 of the head in line with the bar 12, these lugs extending transversely outwardly from the sides of the head and bar.

The upper end of the gravity bar 12 is guided through a suitable bore formed in a bracket 22, somewhat similar in construction to the bracket 16 at the lower portion of the gravity bar, but which is provided above its bored portion with a transversely extending shelf 23. and with a vertically extending back wall 24. The shelf 23 is used as a means for supporting a gravity actuated latching member positioned on saidshelf between the wall 2% of thebracket and. the upper end of the gravity bar. ;This

cut away to permit the passage of the gravitybar therethrough the latching part resting on the shelf 23 at the point of itsangle andbemg retained against laterald splacement therefrom by the pin 2G projecting from thewall 2-): of the bracket and extending between 'the'lugs 27 at the baseof the latch memberi v The lugs Zlcarried by the head of the gravity'bar, rest abovefthebase of the latchbar and they with the head of the bar, serve to maintain 1t in position on the shelf Space is provided'for'the head of the. bar by cutting away thefiverti -i spaced arms 28 between which the bolt head may extend, these arms intermediate their length being provided with shoulders 29 designed to receive the lugs 21 of the bar head in one position of said head to support the bar head therefrom. These bars '28 are perfectly ri idly interconnected by a trans verse spanning portion The upper extP PAltlQS' O l the arms 28 will be positioned on the door in line with abutment means in.

the form of spaced fingers 31 depending from the casing carried bracket plate 5 and :mo\ ed to release the head 19, as will be seen later. This latching member being L- shaped and having its longer arm extending vertically will naturally by gravity tend to swing forwardly. With the door in closed position this will be prevented by reason of the engagement of thefingers 31 with'the upper ends of the spaced arms 28 (see Fig,

2). lVith the door in closed position it will be noted that the hooked portion 20 of the bar head extends'throughthe aperture 6 otthe latch plate and drops downwardly the'reover, the lugs 2l being preferably free from engagement with the'latching member and the "lower end of the bar 12, which forms the second bolt member, being posi tioned backof the abiltment 3; Assuming] now, that the'door is closed and in this position, and assuming also that pressure is exertedjaga nst the cross bar 7 from the injterior of the door, this will, by reason of the arm: 15, move the bar 12 upwardly, its lower end clearing the abutment .3, and the hook 20at its upper end beingmoved upwardly clear ofthe; recessed edge of'the plate 6. This will position the'lugs 21in line with the shoulders 29 of the latching member so that when the door ismoved outwardly the lug 20' \vill be retracted 'throughthe apere titre-6 and, the pressure of fingers 31 being" removed, the latch member will drop .forwardly by gravity from the position 7 .shown in Fig. B'to'that shown in Fig. 3 bringing the shoulders; 29 beneath the lugs 21, so'tha'tfthe "weight of the-bar willrest on; this ;latehing "member.
