The invention relates to door locks.

The primary object of the invention `is to provide an improved doory lock which may be set *so as to be operable by the handles on both sides ofthe door or operable by one handle only, and either operable or inoperable, by a key from the outside of the door.

Other objects of the invention will be apparent from a considerationA of the following detailed description.

f The invention consists in theY several novel :features hereinafter set forth and more particularly defined by claims at the conclusion hereof. f p

In the drawings: Fig. 1 is an .elevation of the locking bolt in its case and its Vshifter device, one section of the case being removed for illustrative purposes and the bolt being shown in its operative or extended position.

Fig. 2 is a similar view showing the bolt retracted. Fig. 3 `is a section taken on the line y3 3 of Fig. 1, the slidable stem for actuating the bolt being shown in the position assumed when the bolt isoperable by either of the handles. Fig. ll is a View similar to Fig. 3 showingthe stemin the posi- "tion assumed when it has been shifted to lock the ybolt against operation by its rotation. Fig. 5 isa Vfront viewr of the outer f rhandle showing the key slot in the same.

Fig. 6 is a section taken on the line 6-.6 of Fig. 1, showing lthe various parts in position to render the bolt operable by either of the handles. Fig. 7 is a viewsimilar to Fig. y6, showing the stem locked so the bolt will be inoperable by the outside handle or by the' y key-'controlled device. Fig. 8 is a perspective of the rotary vdevice for shifting the wbolt. Fig. 9 is aperspective of the slidable stem and the kkey-operated element for shift ing the stem.y Fig. 10 is aperspective of they key. Fig. 11` isf a perspective of the outer handle. l

The inventionk is exemplifiedV in a lock comprising a case ycomposed of a main seotion or bodyllil and a removable section 15. Thiscase is inserted in a door 16. A locking' bolt 17 is longitudinally slidable in the case'and itsv outer end is adapted to pass into the usual socket in the door frame to hold the door ,i closed. The inner portion ofthe bolt is divided to 4form upper and 'lower members 18 to straddle a rotatable shifter member 19. 'At its inner end the bolt isprovided with an abutment adapted to retract the boltwhen said member is rotated 1n either direction from its normal position shown in Fig. 1. Shifter member 19'has i integrally formed therewith a hub 22 journal'led in an opening in case-section 15 and Aa hub 23 journalled in case-section 14.

be engaged by arms 21 or member 19 to hole, and is adapted to rotate said member.

A spring 26 engages the bolt 17, and its inner end is coiled around a shifter stem 27 which has at its inner'end a terminal 28 to engage the stem 25.2 Spring 26 acts to hold normally the bolt' 17 in its extended or locked position. The abutting faces between stem 25'and terminal 28 are shaped to cause the spring to hold the stem in its normal position, and to retract the stem after it has been rotated ineither direction. Stem 25 is provided with .two notches 25a and 25 intov which .the terminal 28 is pressedby the spring, so as to hold the stem in two longitudinal positions. Lugs 30 are formed on the stemr25, and are adapted, when the stem is in the position shown in Figs. 4 and 7 to ente'r'notches 31 in the hub 23 of shifting member 19 and notches 32 in the members k18 oftheI locking bolt to secure thebolt and the shifting member against Vrelative-,movement, so that said member will be locked against .rotation and will be inoperative to withdraw the bolt. When the lugs `30 are. in thel positionillustrated inFigs. 3 and and in the other of which the bolt will be operable by the rotation of said member in either direction.

At the inner side of the door a bearingplate 34 is secured. A v hub 35 on aninside handle isy rotatably and slidably heldin said plate (see Fig. 6). A screw 37 in the hub secures the handle 86 to the stem 25 so thatithe latter Will be `rotatable by the han- 10 dle, and longitudinally movable between its alternative positions by the handle. When the handle 36 is in the position shownfin Fig. 6, the bolt 17 may be Withdrawn against the force ofthe spring by rotation of the .handle and loperation of st em 25, lugs `30,

l i i ufb23, arms 21, and abutment 20. A bearingp'lateB'S isr secured to the outer side .of the door. vA hub 39-011 an outside handle 40 ,is rotatablyniounted in said plate. 'A 20 shoulder 41 ,on hub 39A engages the outer .faceof an annular rib 42 in bearing-pl`ate 38, and lugs 43 on the hub 39` engage the finner lfa ce' jc f rib V42 toV interlock plate 38 and handle`40 to secure said handleagainst longitudinal movement. lRib 42 is formed ,v

.vvith notches through which lugs 43 may be inserted ,in assembling .the handle 40 and VrpflateBS, the ,lugs 4 3 having an operative frange in `which theyyvill `be kept out of A alignment With `said slots after assembling. "When the stem 25` is Vvin the position"illus- .trated infFigs an'd6, the stem is rotatable by the o uterh'andle 4 0, as -Well as bythe inner handle 36,jand consequently the bolt 17may be retracted, either from the inside oroutsidelof the door. Vhenthe stem 22 5 is in the position illustrated in Figs. 4 and ,the boltl-T will be inoperable by the Qut-V side handle 40. I 40 v.A key ioperable .device yis provided V for .st iftingI` the 4stem 25 longitudinally 'When it is desiredthat the door may be,unlocked from the outside by a suitable key. VThis vdevice vo )n sists .of a l`member44 which is 45 1 S li dably connednin a socket 45 in handle 40. and is provided at its innerend With` a hQokQor tooth 46. The latter engages a hook or tooth 47 on the vouter end of stem Av2 3, so .tl 1at the stem `may be shiftedilongi- 50 y tudinally by key-operable member v44. Member 44is provided With a lug 48 fconj fined in arecess 49 inhandle 4 0, to hold themember against rotation in the handle. The upper portion of member 44 is convex, rand has'.longitudinally.extending shoulders l50at the sides thereof. rA tooth 51 isformedf A )'n one ofthe shoulders 50. VThe outer end of socket 4 5 is permanently Closed by va lug 52 which isfformed With akey-slot 53 W lich rcuate in cross seetion to admit a semif hlicalkey v54 l(see-Figs. Y5 and 10). The 'outer end of the provided with a handlel, and the inner en d}is providedfat-Q'Ile ide tvi th a lnotoh 56 which-is adaptedto be rptatedafter vthe key has been vinserted in the key 54 and handle 40. This exemplifies key-operable means for operating the sliding stem to unlock the bolt 17 for retraction.

At times Vit is'desirable to lock ,the b olt 17 sojthat ,it cannot be operated .from the outside with ake vand for lthat purpose a vdevice is provif ed for lookinguthe vste'n1`25 in the position in which it locks the bolt 17 against retraction, andthis/consists of a ring which is rotatablearound the `hub @5pt the inside handle-36. This ring is provided With abutments or cam Isurfaces 56 Whichmay be .turned 'to engage the crests vof cam jsurfaces 57 i formed on the bearingplate 34. {lhis ring fis con'lined by a lug y58v so it will be rotatableI through an arc of yapprniimate ly 900. When the lok'is to beoperablefby either 'the inside kor outside handles, the stem-2 5 *Willgbe Vpushed outand thecams 56 will resti'njthe recesses f5.9 between cam-surfaces 57 on -the flocking plate. In this positionsthe stem25 andfbloth handles will be rotatable to'retract the Vbolt '17, and the inside, handle-36 will be rotatable Without shifting v'the ring. Then it Vis :desired 'to render 'thebolt 17 operablerfromthe outside fonlyfby a key, .the hand'lev'f will be pulled' inwardly'or the s tem'l25 maybe pushed inwardl'ygby "key y54 to shift similarly the 'ghandle 3 6.
