ANTIPANIOLQCK-QPERATIN G MECHANISM.

Application filed December 15,1923.

This invention relates to anti-panic lock operating mechanisms and more particularly to the lock operating devices adapted to be applied to the ordinary type of door locks and latches and to provideready eXit at all times.

The present inventionis an improvement over the invention disclosedin my co-pending application, Serial No. 572,178, filed July 1, 1922, and is in part a continuation of said application.

In mycopending application above referred to I have disclosed a lever actuated lock operator in which the action of the ac tuating lever is cushioned to protect both the lock actuating mechanism and the mechanism of the lock against excessive shock due to violent actuations of the-level or application of excessive force thereto.

In the various modifications of the invention disclosed in said application the casing of the lock actuating mechanism Was shown secured tothe door in a position overlying the lock casing and attached to the door above and below the casing. This mounting of the lock actuating mechanism prevented the use of this device with locks of the type having cylinders projecting to opposite sides of the faces of the door forlocking and unlocking from the inside as \vellas the outside. .ihe present invention has for an object to provide a lock actuating mechanism adapted to be secured to the door at one side of the lock casing and clear of any inner lock cylinder of the lock, permitting the use of: the lock actuating device with doors having locks operable from either the outside or inside.

A furtherobject of the invention is to provide a lock actuating mechanism of the double acting type in which the actuating lever nay be moved in either direction from a neutral position to release thelockand to provide a cushioning device adapted to cushion the action of the lever in either diin-echanism attached thereto.

Referring to the accompanying drawings, Fig. 1 shoiv-sa door-1, which is hinged anld mountedbetvveen the usual door jamlosEZ. In the edge of the door there is-mortised a lock casing 3, this lockibeingof a-well known typeavhichanay be purchased on the .open market. The doorlockconsistsyof a latch 4. which projects from the edge of the lock casing andis adapted to-be locked by suitable mechanism .W'ltlllll the lock casing in projecting posit-ion to .lock the door against opening. The -doorlock is provided wvith. a trip member :6, Which-When moved in an upward direction is adapted torelease the latch locking mechanismaand: operate: the latch to permit the jdoorto open.

adjacent to the lower edge of the lock casing. Thls projection 10 co-a'cts with the trip member 6 of the lock to release the latch i.

'The slide 9 actuates the doorlock when it the outer face of the casing 7.

is moved in an upward direction andis normallyheld in a position in which the pro- 14301510111015 in the lower portion of the recess 11, free of the trip member 6, by means of a compression spring 12 which is mounted within a recess 18 in the upper end of the slide'9. The spring 12 as shown in Figs. 2, and 4 may be entirely within the recess 13 and may engage at its upper end with a plunger 14 which is loosely and slidably mounted outlieupper end of the recess 13 the and bears against the upper end wall of actuator casing 7. "Beneath the spring cess 13 the slide 9 is provided with an "elongated, rectangular slot 15 in which is slidably mounted a block 16, which is inserted beneath a coil spring 17, which iits between the side walls of tllG SlOl] and bears at its upper end against the upper end oi the slot'and at its lower end upon the upper face of the block 16. The lower "face of the block 16 is pressed by the spring 1'? against a projection 19 or" a lever 20, which is pivotedat 21 to a boss 22 formed upon The projecting portion 19 oi 'the lever 20 is normally held against the lower end of the slot 15 in the slide 9 by the spring pressed block 16. The lever 20 is normally held by the slide 9 in a' position in which its outer end is somewhat below the'pivot'21 and its up- 'ard movement is limited by the upper portion of the boss 22. From this position the lever 20 may be swung downwardly toward the face of the door to move the slide 9 upwardly to release the lock. end thelever 20 may be provided with a boss At its outer '23 adapted to'receive a push bar 24 which extends horizontally along the inner side oi the door andis connected at its opposite hen the end toan arm 25 which correspondsto the outer portion of the lever 20 and which is pivoted. to a bracket 26 fixed to the inner ures 2. 3 and i of the drawing.

actuating mechanism will both be protected by reason of the yielding of the spring 17 which will permit the slide 16 to move upwardly in the slot 15 until the lever 20 reaches its limit of movement, thus cushioning-the action of the lever 20 and preventing excessive and sudden pressures being trans- 1 mitted fIOlll the slide to the lock mechanism and protecting the actuating parts of the lock operating mechanism against injury.

In Figures 5 and 6 of the drawing I have shown an auxiliary spring for counterbalancing the actuating lever which may assist or replace the return spring 12 shown in Fig In this modificationthe push bar carrying arm 25 connecting the push bar to the door adjacent to the hinge is replaced by a lever 25, on which is a projection 19 similar to projection 19 of the lever 20 which extends into a casing 26*, which replaces the bracket 25 shown'in Figure 1. ithin the casing 26% there is mounted a vertical movable slide 27 which has a. slot formed to receive the projecting portion 19* of the lever. The

slide 27 is pressed in a downward direction per end of the slide 27 and the upper end of the casing; Spring 28 serves to atleast partially counterbalance the weight or" evers 25 and 20 and push bar 2% and assists holding them in theiruppermost position. The auxiliary spring assists in retaining the lever 111 its uppermost position and permits the use of a smaller return spring for the actuator slide. If desired the sprin 8. may

be made strong enough to entirely replace the actuator return spring in the main casing. However, it is preferred to employ both springs so that the swinging push bar is counterbalanced at both ends.

In Figures 7, 8 and 9 of the drawing I have shown a modification of the invention in which the lock actuating mechanism is double acting, the actuating lever being movable from a neutral position in either direction to release the door lock. In this modification the lock actuating mechanism is Mounted within tlie casing 30 there is .a vertically movableslide 31 which has lateral projection 32 adjacent to its upper end whichpro ectsthrough a slot in the inner wall of the casing intothe recess 11 of the door and is adapted toco-operate with thetrip member Got the lockin exactly the same manner as the projection The in the modification first described. sl1de 311s pressed downwardly in the casing bymeansof a compressionrcoil spring 33 whichis seated in arecess 34 formed in the upper end of the slide 31 andbears at its upper end against the upper end ofthe casing 30. The slide 31 is provided with an elongated notch 35 which accommodates movable parts of thelock actuating mechanism. The actuatinglever 36 has a projection 37 which extends into thenotch and engages with operating members for the slide which will now be described. Adjacent to the upper end of the notch 35 there is atransverse lever 38 which is pivoted centrally at 39 to the front wall of the casing 30. The lever 38 extends transversely across the slide 31 and has pivoted to its ends -depending links 40 and41'which lie along opposite sides of the slide 31. The link 40 maybe provided with a bearingolflguide roller :42 at. its lower endengaging-a sidewall of the casing and has adjacent to its'lower end :a foot portion 43 which projects inwardly into the notch 35 of. the slide. The link41 hasa projection 44 projecting inwardly therefrom and lying within-the notch 35 of the slide above the foot piece 43 ofthe link 40,'the projection 44 being above the: projecting portion 37 of the lever and thefoot piece 43 being below thesaid portion of the lever. The slide 31 has a lateral projection-45which ex tends into a slot 46 inthelink 41loe low'th-e projection 44. The lower end portion of the link41 is reeessedand acompressioncoil spring 47 is interposed between the projection 45 of theslide and the lower-end of the link. The spring 47 reacting between the projection 45and thelower end of:the link 41 tends to force the link-41 downwardly and the downward movement ofthe link41 tends to swing lever .38 about its pivot 39 "and moves the link 40 upwardly. The'spring 47 thus serves to normallypress the projections 43 and 44 of the links against opposite sides of the projection 3701 the operating lever 36. The slide 31 is normally'heldby the spring in a position iii-which the lever is intermediate its upper and lower limits of movement, so that the lever 36 maybe-ac t-uated in either direction from its normal or neutral position. Ifthelever 361s swung downwardly the projecting portion 37- thereof will be moved upwardly engaging the projection 44 and carryingthe li-nk 41-iupwardly. As the link 41 moves npwardly,

upward pressure will be exerted vupon the slide 31 through the compression--spr1ng i47,

causing the-slide '31 to move upwardly to lift .link 41 will causepressuretobe exerted on the-:slide31 through the compression spring 47 and willthus cause the release of the lock in exactlythe same way as upon the downward movement -of the lever. When the lever 36 ismoved in either direction the two links 40- and-41. are caused to move in downward and upward directions respectively, the same result being obtained by the action of the lever upon the projection 43 as by the action of theleverupon the projection 44. Thecoilspring 47 is preferably stronger than the return spring 33 of the slide so that in: normal operation there will be no yielding between theactuating lever and slide.

lVhenever excessive pressure is exerted upon .the'lever due to violent actuation thereof or to the resistance of the movement of the slide the spring 47 will yield and permit relative movement between the lever and slide until the lever has reached its limit of movement and thus protect the door lock mechanism. and the lock actuator-mechanism against damage which might otl. erwise be caused by excessive pressures. Means may be provided to prevent the compression spring .47'from reacting on the compression spring 33 :which serves to return the slide. To this end slot 46 in the link 41 is so diszPOSBd. that when the mechanism is in the nor- :mal position shown in F igure 8 of the draw- ..ing the pro ections 43 and 44 engage the projection 37 of the lever and the projection 45 of the-slide is in engagement with or :nearly in engagement with the upper end of the slot :46. This serves to hold the spring .47 under a predetermined minimum compression during operation since it prevents the springfrom expanding farther than is necessary to bring the projection 45 into en- -.ga-geme'nt with the upper end of the slot 46.

The projection 45 being held at all times :against the upper end of the slot 46 except when the lever: is subjected to excessive pressure the spring 47 i cannot react against the .slide 31 to exerta pressure thereon in oppo- --'sition to the return spring 33 except when m-orethanthe normal operating pressure is r-exer-ted vonthe lever 36.

:The auxiliary counterbalance spring 28 shown in Figs. 5 and 6 may 1 be sadvantageously employed to counterbalance the weight of the swinging push bar in the double acting aneel'ianisn'i above described, the fUHCUOIL of the auxiliary spring in this casebeing merely to-relieve themain actuator mechanism of a portion of the-weight of the swinging push bar permitting a f lighter return spring to beemployed in conlock casing secured therein,'said casing hav- .ing a lock and a trip member for operating the lock, of an opearting device secured to the door beneath the lock casing, said operating device comprising a casing securedto one face of the door, a slide in said casing having 'a projection adjacent its upper end adapted to engage the trip member of the lock, a spring for moving said slide in one direction and a lever for moving said slide in opposition to-the spring.
