EMERGENCY-DOOB-LOCK-OPEBATING MECHANISM.

Specification of Letters Patent.

Patented July 5, 1921.

Application filed September 30, 1918. Serial No. 256,234.

T 0 all whom it may concern:

Be it known that I, WILLIAM B. BoLLEs, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful Improvement in Emergency- Door-Loclr0perating Mechanism, of which the following is a full, clear, and exact description.

This invention relates to a device for use in connection with doors, more particularly exit doors from theaters, halls, and other buildings. v

The purpose of the invention is to provide a means whereby the lock or locking means for a door may be easily operated by a bar, handle, lever, or similar element which is so placed upon the door as to be readily accessible to persons seeking exit.

A further purpose and object is to provide such a mechanism, which is simple in construction, and one in which the parts are so arranged and guided that the parts can not jam, and thereby be non-effective in the process of opening the door.

Generally speaking, the invention may be said to comprise the elements and combinations thereof set forth in the accompanying claims.

Reference should be had to the accompanying drawings forming a part of this specification, in which Figure 1 is an elevation showing a door equipped with locking bolts and operating mechanism for the same; Fig. 2 is an elevation of the mechanism by which the bolts are operated; Fig. 3 .is a side elevation with portions in sec tion of the construction such as shown in Fig. 2; Fig. 4 is an elevation showing a modified form of construction; Fig.5 is an elevation showing a modified form of construction; and Fig. 6 is an elevation showing a modified form of construction.

. Referring to the drawings, 1 indicates a door, 2 and 3 indicate locking bolts for the door which cooperate with suitable detention devices carried in the door frame and by the floor adjacent the bottom of the door.

Either formed as part of these latches, or secured thereto, are rods 4 and 5. These rods are secured to sliding members 6 and 7, such as indicated in Fig. 2. The sliding members are in part mounted within the casing 8, this casing having a cover such as indicated at 9 in Fig. 3, which normally occupies the position shown in that figure.

The casing 8 with its contents is secured to the door after the fashion indicated in Fig. 1.

Within the casing I extend the sliding members 6 and 7, as indicated, and cooperatmg with the sliding member 6 is a Wall 10 which preferably is formed integral with the casing, also a short wall 11, which cooperates with an opposite side of the sliding member. The member 6 also bears against the face of the casing 8 and is engaged by the cover 9 when it is facing any position. Thus the member 6 is held against movement, and the fit between the various parts which engage the member 6 is such as to permit a free movement of the member 6, but nevertheless to prevent any movement in a direction otherwise than substantially linear.

The member 7 also engages in part with the wall 10, and preferably there is a wall 12 which also engages with the member 7 to assist in guiding it in a linear direction. Adjacent the lower end of the casing there is a wall 13, also a short wall 14, which engage with the sides of the member 7 for the purpose of guiding the same.

The member 7 is provided with an exten sion 7 and the member 6 is provided with a recess or socket portion 6 The recess 6 receives a coil spring 15, and the head 7'" of the member 7 extends within the recess 6. and engages with the end of the coil spring 15, so that when the members 6 and 7 move toward each other, the coil spring is placed under compression, which compression serves to restore the members 6 and 7 to their normal position when the pressure which holds spring 15 compressed, is released.

The members 6 and 7 are adapted to be moved simultaneously so that the latches for the door at the top and bottom thereof will be simultaneouslymoved, that the door may be opened.

For the purpose of so joining the members 6 and 7 that they may be simultaneously moved, I employ a pivoted lever 16, which lever is pivoted at its central portion, and at each of its ends is provided with an upstanding pin, as indicated at 17 and 18. The member 6 has an extension 6 which is provided witha pin 6. This extension is preferably provided with a part 6 which engages with a wall of the casing 8, so that as the member 6 and the parts 6 and 6? are and 14, to maintain the same in proper'linear I l arrangement. The extenslon 7 b is provided moved, the bearing of the portion fi upon the casing will serve to take a part of any 6 and 7 to move in a linear direction 7 Link 19 cooperateswith the pins 17 and 6 The member 7 is provided with an exten- ,sion 7? which has. a part 7 that "engages with the wall of the casing 8. This portion 7 serves when the members 6'and 7 are moved,rtogether with. the walls 10, 12,13,

1 with a pin 7?. A link 20 codperatesi with the: pins 7 and 18.

, As .hefoie stated,

7, and forthisfpnrpose, the member 7 is n o rtised 'clear through, as indicated ,ingdotted lines at 7 in Fig. 6. I, Upon'the casing there is pivoted. a lever 21. This lever is provided with a rearwardly extending. portion 21 as indicated in Fig. 3. Above the lever there is a portion of the casing indicated at 22, which in part extends over thatportion-of the lever 21 at which it is pillqtedwsq s to P v n the hand or o g of the Operator from becomin caught behind the lever and preventing the operation thereof, Q The'extension 21 of the lever 21' may be described as substantially cylindrical in its shape except at that'fportionfby which it is 7 top portionof the said opening. The mecha joined to the lever. 21. of the lever extends into-and occupies an opening 7 i which is formed in the member '7, the member 21? normally engaging with the V .nismwhich has thus far been described will fby its operationwill cause the members 6 operate when the lever 21 is depressed, and

and 7 to simultaneouslymove into the casing, or toward each other and compress the springf15 This will at-once be'eviden-t by an examination of the drawingaior when a the; lever 21 is depressed, vit willcansethe I spect'to the casing.

' in'turn cause the link 19 to act upon thepin into the casing. Therefora by theoperation" tion and move the members 6 and' 7 sliding member ,7 to move inwardly with re This movement will causevthe link 20 to raise the pin 18, which will in turn depress the pin 17, and this will 6?, thereby causing themember "6 to move original and normal position.

it may happen that the person endeavoringrto operate the lever 21, would, in the excitementof a hasty egress, grasp the lever I 21 and raiseiit instead ofa-pushingit down,

and in order to provide forssnch acontingency and make it'possible' to release the 4 he lever 16 is pivoted atitscentral portion, as indicated at 1 6, andthe lever 16 extends beneath the memberv The extension 21 locking bolts under such .a situation, I have V provided the following construction; thrust, and assist in enabling the'members The member '7 is provided with a recess the pin 17, and atits 'lowerend has an extension 23 which extends into the recess 7 and normally lies just beneath the portion 7 mortised out. A link 23, coeperates with I V c H 21ofthe lever. -21, .This link 23 is preferably provided with 'a roller24, adjacent its lower end, which engages'with the sidewall of the casing 78 in order to vprovide "a; rolling contact between the roller 24 and -;the wall of theg casing 8, and further to provide a backing for the. lower end of, the "link 23.:

The Y recess 7 is sufficiently extended so that the projection 23 may move through the recess for a snfiicien't distance to accommodate any movement required for the operation of the members of the mechanism.

7 "The link123 maybe formed"integralwith.

the link l9, so that'thelinks 19 and 123' are" in eifect a single operating member, in which event the openingindicated v at. 19? is slightly elliptical inshape. to accommodatefithe slightly circular.movement of the pin 17 as the lever 1 6;tiltsabout its pivot.

*With the members of the mechanism 'ar f ranged as just described, ;if the operating lever 21 be raised, the part 21 of the lever is o depressed, which moves the projection 123 downwardly throughjthe recess 75, int-urn carrying the link 23 idow-nward-ly which I' V communicates its motion to theiink 19 and so through to the member :6, .ca-usingsthe same tocbe movedin a directioninto the casing. The downward movement of link 23' 7, causes 'thelevergltl to tilt, thereby drawing c v in an upward 'directionthe link 20,}which' j in turn cansesthemember7 to-move into'the;

casing;

Thus it willbe'seenthat the slidingmem bers 6 and 7 areoperated ina manner to withdraw the locking bolts :whether; the lever 21 be depressedor raised. r In Fig.7 6 I have shown a construction in which the members 16 and7 are theiqsame as that described, and in fact, most of the parts are exactly the sameythe only -difierence being that the-link 19 and the link 23am formed as independent members. V In Fig. 4:1 haveshown a slightly modified form relating to the manneroiconnection ofthe lever '16 with the sliding member 7. I Inthis constructionthe lever 16 has apin 16*; which cooperates with an-extension formedon the member 7. .This extension is opening, in the portion 7 being slightly elliptical in form so as to accommodate the are formed separately, and; are caused each to engage withthepin'17of the lever 16.

. V InF-ig. 5 therparts are thesame. as :that

lformed adjacent, theportion of thermember, 7 which cooperates with;.;the lever '16, the

shown in Fig. 4, with the exception that the links 19 and 23 are made integral, and at that portion which cooperates with the lever 16 there is an opening 17 which is slightly elliptical in form in order to accommodate the pin 17 in its slightly circular movement.
