TWO-WAY LOCK.

Application filed February 25, 1925. Serial No. 11,491. a

To all whom it may concern:

Be it known that I, CHARLES A. FAIRAND, a citizen of the United States of America, of Watertown, in the county of J etferson,in the State of New York, have invented new and useful Improvements in Two-Way Locks, of which the following, taken in connection withthe accompanying drawings, is

(lesirableto provide a double lock whereby a the door or doors may be locked from both sides, such, for example, as the inside and outside in such manner that each lock is accessible for locking and unlocking at one side only of the doors and the main objectof my present'inventio-n is to provide a double 25 lock of this character which will enable the user to unlock and open the door or doors from either side even though the doors may be locked from the opposite side.

. Another object is to permitthe same look to be used for single or double, hinged or sliding doors.

Other objects and uses relating to specific parts of the lock will be brought out in the following description.-

Inthe drawings: l Figure 1 is a perspective view of a pair of swinging doors equipped with my improved lock. I

Figure2 is an enlarged horizontal sectional-view through the lockand adjacent edges of the doors to which it is applied. Figure 3 is a perspective view of the detached locking device. 7 r

As illustrated the lock is used in connection with a pair of swinging doors l and 1-- adapted to swing to and from open positions in the'direction indicated by arrows :2r!--, Figure 2, and comprises a T- shaped plate --2 having lateral branches and .-4 and an intermediate branch or stem 5 disposed at substantially right anglesto the branches -3- and L between the ends thereof for receiving and supporting a hasp member 6 which is hinged thereto at one end by a pivotal pintle 7-' to swing horizontally through an ar 'lines.

of the respective doors.

ofsubstantially 180 degreesor from one exiLIElIlQPOSltlOIlflS shown by full lines to its other extreme position as shown by dotted -The lateral branches -3 and of the plate 2 are adapted to overlap upon the adjacent faces of one and the same side (but in this instance the inner side)" of the doors l and "1- respectively at opposlte sides of the meeting edges of the door while the stem or branch :5 is adapted to extend between the meeting edges and sliding beyond the outer faces of the doors when the latter are closed to permit the hinged hasp '6' to swing flatwise against the adjacent face of oneof the outer'doors as 1. v r

The inner face of one of the doors as '1 and the outer face of the other door as -1' are provided respectively with staples 8 ing plates '9% and 9- which in turn are secured by screws -10 or other suitable fastening means to the adjacent faces and'--8- mounted upon suitable support- 'The'staple --'8.' is slidable inwardly and.

outwardly through guide openings-in the plate -9-''andarecess l1 in the adjacent part of thedoor so as to,facilitate the locking and releasing of the adjacent arm clasp 4-- of the vplate f2, said arln 4 being provided with a lengthwise slot .12 of just sufficient size to permit the staple 8v to pass easily therethrough.

Other suitablelocking members as 13 may be passed through the staple 8- a nd against the adjacent arm 4 for locking said arm to the door as l' and therebyholding the door in its closed position when the other door as --1- is closed.

' The hasp -6 is also provided with a lengthwise slot -12 of just sufiicient size to permit the passage of the staple 8-- therethrough or rather to permit the hasp to be moved to and from a position embracing said staple when the-door is closed after which a suitable locking member as 13- may be inserted through the staple and across the adjacent face of the hasp 6- to hold the door in its closed position.

. .A stud 14- iszslidably mounted'in a socketed plate 15 on the sideof the door 'l adjacent the branch arm 3 of the plate 2 and is spring-pressed outwardly by a coil spring l6 into an opening ,1T- in the branch 3 for add tionally supporting the plate 2 and also affording additional locking means for the doors particularly if they are slidable instead of swinging, the outer end. of the stud -14- being rounded or beveled to enable the branch 8 to ride against and depress the.

same when the doors are closing.

Operation." 7

Assuming now that the doors are hinged to swing open in the. direction indicated by arrows -w and areboth locked inside and outside by their respective locking members and "13 and "keepers --8' and its open position.

Assumingragam that both doors are locked in -their closed positions from both sides, and that the user wishes to open the doors from the outside in 'whiohcase it is simply necess'any to removethe locking member v13 and then to swing the hasp 6' from .the position shownby full lines to' the position Qshown by dotted lineswhich permits the door -1"- to be swung open after which :the door -V-1- may also be opened.- 7

On the other hand after the doors are hinged to swing inwardlyor in a direction opposite :thatindicated by thearrows and they are, both locked inside and outside and it is desired to open the doors from the inside,the

looking member- 'l3,+ may be withdrawn thus permitting bOtlIa'GlOOlS to be opened inwardl-y oreif it is desired .to open the doors inwardly from the outside the locking mem- I ber '-'13. f-;may be withdrawn and the hasp looked to a position substantially parallel with the: stem'-5- thus permittingthe door =1 to be opened sufliciently :to disengageits branch 3- fromthe stud -l4 and thereby to allow both'doors to be opened inwardly simultaneously. v x;

Iffthe' doors are adapted to slide toward and zt'rolm each other -and arefboth locked from the inside and outside and it is desired to open them, from the inside the locking member -13-'inaybewithdrawn and the staple -8- pushedlby hand into the recess 1 1: beyond thepadj aoentarm 4 of the plate 2 thus permitting. either or both of the doors to be: opened; r i

Again assuminglthat the doors are slid able and are both locked from the inside and that itis desired-to open the doors from the outside in which case it is simply necessary to remove the locking member 13- and to swing the hasp 6 out of engagement with the staple'8 whereupon the hasp 6 may be used as ahandle by which to force the end branch 3 of the plate 2- out of engagement with the stud -14 whereupon either or both doors may be moved laterally away from each other to their open positions. V

The extreme end of the branch --3'and also the end of the stud 14 are rounding in cross section to enable the branch 3- to ride upon and depress the stud -14 against the action of the spring -16 into the opening l 7-'-. 1 a I VVh-ile the sliding'doors are still open the arm -4c'- of the plate.'2 be'loeked from the inside in the mannerpreviously de M scribed after which the user, may pass out through the open doors and close" them and lock them from the outside by means of the ha sp- -'6- and locking member 131 or if it is desired to lock the garage from the inside the operator may firstflock the hasp to the staple 8-' by means of the locking member -'18'--' and then after the doors are closed the staple -8 may be withdrawn outward-1y through the then registering slot 1'2' at the arm and locked by means of the member -1'3. V

In a similar manner the doors may be double locked from the outside orfr'om -the in- 7 erably located equal distances from themeet- :ing edges' of the doors and in'l i ke manner theslots in the 'hasp arms '-4 and -'6eare arranged equal distances'from the meetedges of the door thus permitting'the de- Vice to be reversed so that the arms and 6imay take the placeofea'c'h other in which case the stud --14-- would; of

course, be ineffective, but in some instances this stud -1 4= and its operating spring 16 may be entirely dispensed with without departing from the essential features ofthe invention.

hat I claim is: y l A double door lock of the character described comprising a T-shaped plate having its stem adapted to pass between the meeting edges of the doors andits branches adapted to overlap upon the adjacent sides of the doors, one of said branches beingprovided with a slot, a hasp hinged to thestem to swing to and from a position across the opposite face of one of the doors and provided with a slot, keepers on oppo'site'faces of the doors adapted to enter the adjacent slots and U locking members engaging said keepers.

In witness whereof I have hereunto set'my 1 hand this 19th day of'February,-1925. r
