f citizen oft the United States, residing in the Vlat-ch from the outside of thedoor, and con? town of 'East Haven, county of New Haven,`

and State of Connecticut, have invented certain new and useful lmprovements "in,y Locks, of which the following afull, clear,` and exact description.y A l This invention relates to locks, and' more e particularly to latch bolt locks for fschoolhouses and similar buildings,havingrneans 1\'\='hereby the'latchv'bolt maybe ,held back yin y f the case When retracted by ther key.k 1n' yanV application iled July 2 0, 1912, Serial No; 710,570, resul-ting in the grantof Lettersf latent No. 1,126,560, January 26, '1915,'1

have described a lockk having niechanismf operable by a key for retraotinglthe latch bolt, and holding yit in retractedposition, which mechanism Was'primarily devised for the vconvenience of the janitor ofthe build-f ing, so thathe could readily "stop backtheV latch. lVhen it' was merely desired to unlock" the door temporarily, 4the janitor could, by a reverse movement oit 'the key, readily-'release the latch, after it 'had been` lockedfin" retracted position'as a neicessjaryresult of `its Y retraction. Certain doors ofthe bu'ildin, however, are in use by the teachers, and in entering such doors, the teache'rqoitenomits to give 'the lreythe necessary `4movement to e release the retracted latch, whereby thev doorslarefrcquently left unlock-ed at Vtimes whenI they shou'ld'be locked against intrusion from the outside. Moreover, it hasbeen found. desirable to-prevent the stopping back kof Ithe tine this function to mechanism-i` operable,` `from the inside oiithe door, vthough permit-' ting retraction ofthe latch from either side.

rThe primary objects oi the presentjinvenj tion are |to meet thek above conditions; to: provide a latchV bolt lock-"havingavbolt, re-y tractable by akey or key's'inserted ateach` side oi' the dooigiinechanism being provided 'tor stoppingback the latchy When-it re? f tracted from oneV side Without stopping'it` back Whenit is retracted from ythe other side; to provide a locx' having a key for-re.

Referring to the drawings, the case spring 13. The stem 14 of the latch bolt VVcarries a head l5,L engaged by-a lever 16,

adapted to beoperatedbya lifter 1T,'Which is inturn actuatedby an insidethumb'piece,

pushbanorother mechanism (not shown). Thewparticular .means for retract'ing the latch boltmanually from thev inside of the rvdoorfisiiinrnaterial;`P In-the particularl lock .selected for'. illustration," the retraction of the bolt from the outside` ofthe door is confL fined tothe key, but thisv isilikewise an immaterial Ifeature.

fllhe means for retractingjthe latch bolt, by meansof a key, comprises a latch bolt retractinglever 20,'vpivoted in the'case'at 2l,

yvithfthe ycrosshe'ad 15 of the bolt. --The retracting lever 20 ispi'ovided With a projec-` F 'gT 6 is a detaili-otthemain de'tent lever 1o of the lock, having thek faceplate l1, contains e a latch lbolt 12, normally l'projected by a so f and having one extremity thereof engaged ico ing'the arm 24: tothe right; This arm, by

engaging the projection 23, carries With it j in its ,movement 'the retracting lever 20, wherebythe Vlatch bolt i's'retracted. Acyl- Il 1 Vcreate a pointed projection as shown.

end 3l loosely rests on, and is supported by,

a lateral projection 3% on the lever 20. The parts are so arranged that when the bit 30 is turned in an anti-clockwise direction, with respect to F ig. l, it will be unable to Contact Ywith the projection 2a of lever 25, but will,

on the other hand, depress the lever 32 and actuate the lever 2O to retract the latch bolt without moving the lever 25 to any appreciable extent, as shown in F ig. 2. l have not considered it necessary to illustrate the pin tumblers with which the cylinder locks 23 and 29 are provided, as this ieature is Well understood in the art.

The arm 2e of the lever 25 is made of special shape so that as said arm is actuated by thebit of the inside cylinder lock 28, it may operate to hold the latch bolt in its retracted position. To this end, the edge portion of the arm 2a, coactiug with they projection 23 of the latch bolt lever, is formed with a shoulder 39, having inclined edges l0, atl, directed at an angle to each other,-.to As the latch bolt is retracted by the lever' 25, the edge t0 of said Shoulder or projectionbears against tie projection 23, as the arm 24: moves toward the right With respect to Fig. l.y As the movement of the arm 2e continues, the shoulder 39 and projection 23 move relatively to cach other in such a inanner that as soon as the latch bolt has been fully retracted, the projection 23 on `the 'latch bolt lever passes the apex of the shoulder 39,4 andV snaps into position against the edge al oil` said shoulder, whereby the lever and the latch boit l2 are locked in retracted position. n order to increase the security with which the latch bolt is held in this position, the detent lever-25 is provided with a rearwardly directed extension which, as the projection 23 passes from one side to the other oiE the shoulder 39, snaps into position front of the crosshead i and engaees said crosshear` irictionally, as shown in i* igs. 3 and il. in this manner, the latch bolt is held securely in retracted position. and it will remain in such position Until the bit 2T is rotated in a direction opposite to that lirst indicated, in order to cause the abutment of the bit 27 iinstithc opposite side the j )rojection 2st and the release oi' the lever whereupon the parts Will be restored by the latch boltspring to the initial position.

lVhen the latch bolt has been locked in retracted position by the de tent lever 25, it

will, preferably, be releasable by a key inserted at the outside of the door, as Well as by a key inserted at the inside. The actuation of the lever by the bit 30, as the latter is moved in an anti-clockwise direction with respect to `Fig. l, is prevented by the means already described, but there are no means shown for preventing the release of the lever 25 by contact of the bit 30 with the projection 24;, as said bit is moved in a clockwise direction with respect to F ig. 3. Preferably, the inside and outside cylinder locks 2S and 29, respectively, will be operable by dierent keys, such as the keys Ll5 and le respectively, shown in Fig. 7. rl`he key may be termed the janitors key, because in operating the cylinder lock 2S from the inside oi' the door, it will retract the latch bolt and stop it back in the case. The key 46 may be termed the teachers key, because when inserted in the outside cylinder lock 29, it Will retract the latch bolt without, however, being operative'to stop it back in the case. By the construction describen, the actuation of the outside key in opening the door for entrance cannot alter the normally locked condition of the door when the same is closed. lVhen it is desired to stop back the latch, the janitor may readily do so by insertion of his key at the inside Without necessitating the opening of the door. Moreover, When the teachers key will not operate the inside cylinder lock, as in the 'form illustrated, manipulation of the detent mechanism for the latch bolt is confined to the janitor alone, Which is desirable in some cases, but this is not an essential feature in all aspects of the invention. ln the forni illustrated the manually operable latch re tracting mechanism 16, 17,- at the inside or" the door, is similar in its function to the outside cylinder lock in so tarV as it is incapable of operating the detent lever to stop back the latch bolt. Y

In the particular form shown, the latch bolt is dogged automatically on the closing or' the door by means of a clogging lever i7 acted on by a spring 4:8 in such a manner that the head of such lever tends to lie in the path of the latch bolt so as to block the i' incursion of the same. The lever 47 is held out of blocking position with respect to the latch bolt by a projecting controller bolt which is forced in by contact with the strike so as to cause the bolt to be dogged by the lever. automatically on the closing or' the door. ln opening the door, a projection 5f) on lever 2O engages a shoulder 51 on the tail of lever 4:7 in such a manner as to swing the lever out of the path of the bolt head in the usual manner. In order to move thc. dogging lever out ofthe path orn the bolt when the latter vis to be retracted by the manual vretracting means at the inside oie the door,

the lever 16 acts on the lower extremity of i'io lll

the latch boltto be freely retracted. These features. in themselves are old inthe art, but it will be apparent thatfbythe construction described, the latch bolt may be rev-K' tracted by the manual retractlng means indefV pendently of the detent mechanism, and that thereafter the detent mechanism may be moved by the rollback 27 toa position to dog` the bolt in the retracted position. In other Words, while the bolt is held back by the depression of the thumb piece, it may be dogged in retracted position by one of the keys but notiby another key, said first key operating the detent leverindependently ,of Y
