Tovzll whom it may concern: I

Be it known that I, VILLIA'M B. BOLLES, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented a certain new and useful Improvement in Antipanic- Lock-Operating Mechanism, of which the following is a full, clear, and exact description.

Thisinvention relates towhat is known in the trade as an anti-panic lock, which de vices are placed .upon doors forming closuresfor the' exits of buildings, and are. so designedand arrangedthat the lock operating mechanism may be easily operated...by the contact of any portion of the bodyof a person with the lock operating mechanism, thus not necessitating the turning of a knob, so that in thcleven t acrowdsurges against thedoor closing 'the'eXit, the lock operating mechanism will be easily operated and so permit the door. to. swing outwardly and permit egress from the building.

The object is to provide a locking mechanism which. permits the door to be kept locked, but also permits a ready. operation of the locking mechanism from the inside of. the door.

"The object of this invention is to provide a lock and lock operating mechanism which is of'simpleconstruction and dependable. in its operation.

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

.Reference should be had to'the accompanying drawings forming a part of'this specification in which Figure 1 is a partial elevation of a door in its usual mounting, equipped witha lock and lock operating device of my invention; Fig.2 shows a form of mortise lock which may be used in connection with the lock, operating mechanism of my invention; Fig. 3. shows partially in elevation and partially in section a door equipped with a' lock and lock operating mechanism; Fig. 4cis a rear'elevation of one form of lo k operating mechanism; Fig. 5 shows an'elevation of a door equipped with a different form of locking mechanism and in connection therewith a lock operating mechanism of my invention; Fig. 6 is a side elevation with portions in section of a modified form of lock operating mechanism; Fig. 7 isa rear elevation of the showing in.

Fig. 6; and Fig. 8 is a; transverse section showing. an. operating lever and connecting parts for the lock operating mechanism.

The look as here .shown may be provided with a key opening .which will cooperate with a key-l10lewl1ich opens to the exterior of the door, so. that the lock may. be operated. by a. key insertedupon the exterior of the door. Other types-of locks may be used, but the main object. here sought is to provide. accessible and. easily operable mechanism. which will undera'll conditions operate the lock of thedoor.

'I-n'-Fig. 1.,a.door isindicatedat 1, which is hinged .and mountedjbetweenthe: usual door. jambs 2, at the :usual place iILtl'lBrdOOI', and. .in'fthe. edge of the door there is mortise'd in, a lock such as indicated, in Fig. '2. This'l'ock' is of ,a welleknownftype which may be purchased upon the open market, and no particular description ofthe :lo'ck will be given except to. indicate the portion oi the-1ock which. cooperates with the lock operating mechanism of, my invention; and at this point I wish tostate thatin making reference'tothis particular lockI do not confine myself .to-a lock having the particular operating mechanism herein shown and described, as other'loc'ks may; be used which will. cooperate with the lock operating mechanism in" "the manner herein described.

Reforringto Fig. 2, the locking belt or latch is indicated at 3. This latch hasa rearwardly extending portion4 which hasa head 5. The head is engagedby ,a reciprocating member '6 which has a hookedhead 7 that engages .with'fthe head 5. Atfthe rear portion the member'6 engages withv an armZS of a pivoted lever, this lever being pivoted at 9. The lever also has an arm 10 which cooper'ats with an operating member ll. .The operation of so much of the look. as "shown and described, will be readily understood, for when the lever} 11 is pressed upwardly, the arms 10 and 8 are moved in a direction which results in pulling the latch .or bolt 3 inwardly with respect "to the lock casing. The various elements in the lock are solarranged that by spring pressurethey will be returned totheir normal position when pressureagainst' the member 11 is relieved.

Upon the inside of the door "there. is secured a casing'lQ. "This casing at the lower portion is provided witha recessed part 13 thatreceives the lower end of a movable memb r 14, .At thenpper part of the casing there is a recessed member 15 which receives a spring 16. This spring bears upon the upper end of the member 14 and the normal action of the spring is to depress or push the member 14. The back portion ofthe casing is closed by a plate member which is engaged at 17 in Fig. 3, the plate member cooperating with the member 14 to hold the same within the casing.

Upon the outside of the casing 12 there is pivoted an arm 18. This arm extends outwardly and is in position to be engaged by the person desiring to operate the locking mechanism on the door. The arm is pivoted as indicated at 19, and has a portion 20 which extends behind the pivot 19. This portion 20 extends within a recess 21, formed in the member 14. The member 20 has a rounding surface which engages with the opening 21. and is designed so as to have an easy fit within the recess 21. Also the width of the recess 21 is but little greater than the width of the portion 20. As the lever 18 is moved inwardly toward the door to the position indicated in dotted lines in Fig. 3, the head or end 20 cooperates with the member 14 causing the same to be raised against the action of the spring 16, and when pressure against the lever 18 is removed, the action of the spring 16 is to return the member 14 to its original position.

It will be noted that the head 20 while movin the member 14, assists materially in guiding this member and keeping it in alinement.

In the door itself there is formed a recess 23, and this recess is adjacent the lower part of the lock and more particularly that portion of the lock which accommodates the presser member 11. Into the recess 23 there extends a pin or arm 24, this arm being secured to the member 14 and moving with it.

The arm 24 is positioned to be directly below the presser member 11 of the lock so that when the member 14 is raised by operation of the arm 18, the pin 24 will contact with v the presser member 11 for the purpose of withdrawing the latch or bolt 3 in a manner which will be understood from the preceding description.

The member 24 is positioned with respect to the member 11 of the look so that the movement ofthe arm 18 will move the pin 24 the proper distance to operate the presser member 11 of the lock, that is to say, if the movement of the arm 18 is of such an amount that the pin 24 would move a greater distance than the presser member 11 of the lock, the pin 24 will be spa ed from the member 11 of the lock so that the total movement of the member 24 will be no greater than is necessary to operate the member 11 of the lock.

InFig. 5 there is represented a door 25 which is equipped with a different type of locking mechanism than heretofore described. The looking mechanism in the figure to which reference has been made comprises a bolt 26 at the top of the door, and a bolt 27 at the lower portion of the door, these bolts being suitably held to permit reciprocation. The

bolts

26 and 27 are adapted to engage suitable openings formed in the lower sill of the door and the upper portion of the door case. The

bolts

26 and 27 are operated by suitable rods 26" and 27 which preferably, although not necessarily, are made integral with the bolts.

Upon the face of the door is a casing 28. This casing is secured to the door in any desired manner. Within the casing there is a reciprocating member 29 and a reciprocating member 30. These members are in alinement and are suitably held within the casing to permit their reciprocation. The rear portion of the casing is closed by a cover 31 which holds the parts within the casing and assists in guiding them in their reciprocating movement.

The lower portion of the member 30 is provided with a recess 32 which accommodates a portion of the spring 33, the other end of the spring engagin with an end of the member 29. The spring 33 normally acts to push the

members

29 and 30 apart.

Pivoted to the casing 28 is a lever 34. This lever is mounted upon a pin 35 which is screw-threaded into a suitable opening in the casing. The pivoted portion of the lever 34 is in front of the member 29, and for this purpose the member 29 is inortised out to form an opening as indicated at 36 in Fig. 6. This permits the lever 34 to swing about its pivot, at the same time permitting longitudinal movement of the member 29.

The lever 34 is pivoted as heretofore described, at the central portion thereof, and at the ends is pivotally secured to

members

37 and 38 which are respectively pivoted to

arms

39 and 40, which are respectively car- .ried by the

members

29 and 30. It will thus be seen that the

members

29 and 30 are joined to each other in such a fashion that movement imparted to one will efi'ect a movement of the other and in a direction opposite to that in which the first member is moved; that is to say. if the member 29 be elevated, the member 37 will be raised, causing the member 34 to be moved to a substantially horizontal position which will in turn, through the member 38, cause the member 30 to be moved inward or toward the member 29, and against the action of the spring 32. When the force moving the member 29 as just described, is removed, the expansion of the spring 32 will push the

members

29 and 30 apart and the connecting link mechanism just described will be caused to assume the position shown in full lines in Fig. 7.

The member 30 is connected with the rod 26 which operates the upper bolt 26, while the member 29 is connected with the rod 27 which operates the bolt 27. 1

In the casing there is mounted .an arm 44. This arm is pivoted to the casing as indicated at 41. Behind the pivot 41 there is an extending portion 42, the surface of which is in part cylindrical. This portion 42 extends into a slot 43 formed in the member 29, and as previously described with respect to the construction shown in Figs. 1 to 4, the member 42 has aworking fit in the slot 43 so that when the lever 44 is moved, and as a consequence, motion is imparted to the member 29, the head 42 in addition to moving the member 29 serves to guide the member 29 in its movement.

From what has previously been described, the operation of the device will be apparent.

Having thus described my invention, what I claim is:

1. In combination with a door and locking bolts therefor, acasing adapted to be secured upon the door, two members mounted within the casing and guided in their movement by the casing said members being adapted to reciprocate in opposite directions parallel with the door, means connecting the said members with the locking bolts, a lever pivoted between its ends upon the casing, links connecting the ends of the lever with the said two members whereby the said two members operate in unison, means within the casing for normally urging the two members away from each other, an operating member pivoted upon the outside of the door, a direct articulated connection between the operating member and one of the first mentioned members.

2. In combination with a door and locking bolts therefor, a casing adapted to be secured upon the door, two members mounted upon the door in substantial alinement, said members being adapted to reciprocate in opposite directions and parallel with the door, means connecting the said members with the locking bolts, a spring engaging the adjacent ends of the said members and normally urging them apart, a lever pivoted between its ends, upon the casing, links connecting the ends of the lever with the said two members whereby the two members operate simultaneously, an operating member pivoted upon the outside of the door, a direct articulated connection between the operating member and one of the first mentioned members.

3. In combination with a door, and locking bolts therefor, a casing adapted to be secured upon the door, two members mounted upon the door and adapted to reciprocate in o posite directions arallel with the door, connections between the said members and the locking bolts, means normall urging the two members away from each other, one of the said members having a cut out portion, a lever pivoted between its ends tothe casing and in part occupying the cut out portion of one of the first mentioned members, links connecting the opposite ends of said lever with the said members whereby the members operate to ether, an operating member pivoted upon the outside of the door, a direct articulated connection between the operating members and one of the first mentioned members.

In testimony whereof. I hereunto afiix my signature in the resence of two witnesses.
