reisen i i LOCK.

Application filed, rTune T0 all 107mm t muy @meer Be it lrnoivn that l, JOHN Fn'ersnvosn a citizen ot the United States, anda resi dent ot' Stamford, in the county oi? .i :held and State ot Connecticut, have vented certain neiv and usetul lniprovements in lioelrs; and l do hereby declare the 'li'ollovving to be a full, clear, and enact description oit the invention, such as Will enable others skilled in the art to which it appertains to maire and use the. same.

rllhis invention relates to improvements in locks and more particulaii'ly to such es may :be used for doors and the lilrelfone object ot my present invention being to proH vide o lock having a plurality otbolts adepted to have such interlocking connection ivith the strike or keeper as to prevent separation of the lock casing and the keeper or other- Wise j aicking of the lock With the use oit a jimmy or other burglars tool, and to so construct the loclr that the bolts will properly and etiectuelly interlock with the -lieejl Without necessity `for causing the lock casin to project beyond the edge of the door.

Vi7ith this and other objects in view,n the invention consists in certain novel tentures of construction and combinations ot parts as hereinafter set forth and pointed out in the claim. Y i

ln the `accoinpanying drawings; Figure l is a longitudinal sectional view ot a look embodying my improvements; Figure 2 .is a rear face view With cover plate ot the casing removed; Figure 3 is un edge vievv oit the main bolt structure; Figure l is a tace view of said main bolt structure; Figure 5 is en edge view of the auxiliary or deadiloclring bolt structure; Figure G is a tace view ont the structure shown in Figure 5; Figi-ire 7 is a sectional vieiv partly in elevation shoviing the bolts in retracted positions, with certain partsY ot the operating mechanism omitted;` Figure 8 is a transverse sectional view of the structure shown in Figure 7 with the bolts projected, but omitting the keeper and showing the spring for the tumbler 28, and Figure 9 is a view similar to Figure 7, but omitting the keeper and showing the bolts projected.

In the drawings l have represented my improvements with a loclr of the rim type, but it will be understood `that said improvements might be embodied in locks of other types. The easing l ot the lock may 1922.. Serial No. 565,33L

be secured in any suitable manner to e door so that one end thereof Will lie flush with the vertical Jfree edge ot said door, and the lreeper 2 may be secured to the door trame or joinb so as to be tlush or in alignment With the inner tace ot said jami. The Vieeper 2 is provided at its open side with lugs or cross members 3, 8, which are so spaced apart and trom the upper and lower walls ol" the keeper as to provide openings 5j 6, tor the passing into the keeper oli bolt members carried by the lock casing es more fully hereinafter described. i

rlChe main bolt 7 ot the lock comprises a plurality ot bolt members 8, 9 and l() carried by und integral with a body or apron member il mounted to slide on Ways 12 Within the casing. The body portion ot the mein bolt carries a talon 13 to be engaged by one or another pin lll carried by e cross head l5 secured to the spindle 16 of a knob 17, for projecting or withdrawing the bolt. rlhe lrnob spindle and cross head may be held in the position to which the same may be turned by rictionel engagement of spring arms 18 .vith said spindle as indicated in Figure 2.

The members 8 and 9 of the main bolt structure are made hollow as shoivn in Figures l', 8 and 9 and es indicated by dotted lines in Figures l to il, and the top Wall et the intermediate bolt member 9 is provided with an opening 19, While the lower bolt Vmember l0 is provided with a socket 20.

ylhe tree ends ot the several members S, 9, l@ ot 'the main bolt lie flush with the end ot the casing l when the main bolt is in Withdrawn position and said end ot theI casing is provided` with e plurality ot openings tor the passage ot seid bolt members,

in auxiliary or dead locking' bolt structure 2l, shown separately in Figures 5 und 6 ot the drawings is carried by the main bolt structure and is movable transversely With relation thereto. The auxiliary bolt structure comprises a body portion 22 so asso-` ciated 'with the body or apron portion ll ot the main bolt structure as to be `movable transversely of the and `urms 23`n` 2li movable in the hollow main bolt members and provided With integral bolt members 25a 26. located in alignment with each other and both projecting in the same direction. The construction. is such that When the main bolt is projected into the keeper, the auxiliary bolt members 25, 26 will be caused to become disposed across the spaces between the main bolt members 8, 91 lO and behind the lugs or cross members 8 ot the keeper-, the tree end of the auxiliary bolt member 25 entering` the hole 19 or the main bolt member 9 and the free end of the auxiliary bolt member 26 entering the socket 20 in the main bolt member l0. lV hen the main bolt is in withdrawn position, the arms 23-24 and the bolt members 25-26 of the auxiliary bolt structure will be housed or enclosed within the hollow members 8-9 ot' thn main bolt structure as shown in Figure 7.

The body portion 22 of the auxiliary bolt structure is provided with a talon 27 with which one or the other el: the pins la oi the cross head 15 is adapted to cooperate to slide said auxiliary bolt stru-#ture transversely of the main bolt structure atter the main bolts shall. have been projected or withdrawn.

The talon 2T ot' the auxiliary bolt structure carries a tumbler 28 having' a lugay 29 to travel in a slot 29n in the main bolt structure when the auxiliary bolt structure is moved transversely of said main bolt structures. A spring' 80 serves to press the tu abler 2S rearwardly so as to cause its lug` to enter an enlarged portion 3l at one end or the other of the slot 29 and thus lock the auxiliary bolt structure in its projected position shown in Figures 2, 8 and 9, or in its retracted position with the arms 2B. 24 and bolt mem bers 25, 26 housed in the main bolt members 8 and 9 when the bolts are in retracted positions within the casino'7 as shown in Figure 7.

I have hereinbe'lfore described knob operated means for controlling` the operation of the lock, but it will be understood that key operated means may be provided also to operate the look trom the outside ot the door. ln Figure l of the drawing. l have indicated a roll bark cam 32 carried by the cover plate 3?, oi the casingv tor cooperation with the bolts and this cam majY be operated bj.' any suitable cylinder lock or other key operated construction not shown, as will be readily understood.

Then the bolts 7 and 2l are in locked relation to the keeper as shown in Figure 2. they may be retracted by operation ot the knob in the followingr manner: lVhen the knob spindle is turned to cause movement ot the pin il at the lower end cam or cross head l5 in the direction indicated by the arrow, said pin will operate first to depress the tumble-r and move its lug 29 out ot locked connection with the main bolt 7 and enter the talon 27. As said pin continues to move upwardly it will7 by cooperation with said talon, cause the auxiliary bolt structure to be moved upwardly to withdraw the auxiliary bolt members 25` 26 into the hollow main bolt members 8, 9 and during such upv-.fard movement ot the auxiliary bolt structure, the lug 29 of the tumbler 28 will pass upwardly through the slot 29l and when the auxiliary bolt member 25, 26 shall have been fully retracted into the main bolt members 8, 9, tl e tumbler lug 29 will snap into the enlarged upper end portion lll olE said slot and thus lock the auxiliair-y bolt members in such retracted positions. As the operating` pin 14 continues to move in the are ot a circleg it will engage the talon l?) on the main bolt structure and retract the latter and the auxiliary bolt structure earried thereby7 into the lock easing.

Slight changes might be made in the details ot construction ot my invention without departing from the spirit thereof or limiting its scope as defined by the appended claim and hence l do not wish lo restrict myselin to the precise details herein set forth.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is

ln a lock structure, the combination with a lock easing and a keeper, et a main bolt struct-ure mounted in the casing. an auxiliary bolt structure carried by the main bolt structure and movable transversely oi the latter, said auxiliary bolt structure having bolt membei having interlocking' cooperation with the keeper` a spring-pressed tumbler carried by the auxiliary bolt structure and cooperable with the main bolt structure to lock the auxiliary bolt structure either in retracted or projected position relatively to the main bolt structure, manually operable means cooperable with said tumbler to nnlock the auxiliary bolt structure Vfrom the main bolt structure and ttor moving said auxiliary bolt structure to projected orretracted position1 and means ooperable with said manually operable means whereby operation of vthe latter will project or retract the main bolt structure and auxiliary bolt structure relatively to the lock casina and keeper.

ln testimony whereof, l have signed this specification in the presence oft two subscribing' witnesses.
