INVENTOR ATTORNEY Patented June 17, 1930 ALBERT VAIGEKAUCKAVS, oF Rooxronn, ILLINOIS LOCK application mea 'December 14, 192s. serial, No. 325,963.

This invention relates to a keyless lock of the mortice type, the general object ofthe invention being to provide means vwhereby the dead bolt can only be manipulated from one side of the door or barrier7 thus making .it impossible to manipulate said bolt-from the other side of the door,thereby providing a burglar-proof lock. Y

A further object ofthe inventiony is 'to make the parts adjustable so that the lock manipulating means can be placed on either side of the door andalso to make the latch bolt slidable on the deadr bolt so thatboth bolts work .in one hole 'formed in' the lock casing and the strikerI plate.

A still further object of the invention is to provide a rotatable member having a handle'thereon, mounted on a part of the knob stem, for manipulating the dead bolt, and to gg provide a dog for locking the dead bolt in either retracted or projected position.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to' be hereinafter fully described,y illustrated in the accompanying drawings and specifically pointed out in the appended claims. y

In vdescribing the invention in detail, refer- '30 ence will be had :to the accompanying 'drawings wherein like characters denote like or corresponding parts throughout theseveral views, and in whichyt Figure 1 is an edge view of portion of a door, showing the improved lock' applied thereto.

Figure 11 is a perspective view of the latch bolt, showing the parts thereof separated.

Figure 12 is a view of the striker plate.

In these drawings, the numeral 1- indicates the casing of the lock which is morticed in ou the door A in the usual manner, said casing including a covery plate 2 and the front plate' 3 which is countersunk in the edge of the door and which is formed with a single opening' 4 for the latch bolt 5 and the dead bolt 6. 65 The latch bolt is formed with the grooves 7 in its outer part, oneof which receives the guiding rib 8 onY the outer part of the dead bolt and the other receives a projection 9 formed on the top wall of the opening 4. The 79 latch bolt is formed with a central opening 10 into which extends a projection 11 formed on the casing and a spring 12 is arranged in said opening and bearsv against the projection and the Afront wall of said opening and acts t0 hold the latch bolt projected.v The forkednpart 5 of the latch bolt is fastened tothe front part thereof by the screw 5 so that this-forkedpart can be reversed, whereby the llockcan be used either as a left hand lock .imk ora right hand lock, thus enabling the dead bolt manipulating means to be placed on' either side 'of the door. v' f Y Thel lugs on the ends of the prongs of the forked' part areV engaged bythe projections 85 13 on the member 14 throughwhich the Vstem '150i the knobs or handles l'pass so that by partly rotating the knobs orv handles,y this member 14 will berocked to retract the latch bolt in the usual'manner. This member 14 90 has a reduced part iitting in a circular hole inthe cover-plate of the casing and the reduced part on the otherfpface of said member 14 lits iiiy a' rounued recess in a ring kmember 17 whichhas a reduced part tit-ting yin a cir- 95 cular hole inthe casing`r the opening in the ring part being made of larger diameter than the knob stern so that the stem can pass there- `through and be rocked without moving said memberl'?. The reduced part `of this meni- '100 ber 17 is formed with the oppositely arranged openings 18 and a sleeve 19 is rotatably lmounted on apart of the stem and eX- tends through the escutcheon plate 2O on one face of the door and through a part ot the doer and has oppositely arranged ears 21 on Y its inner end which enter the notches 18 so that when this sleeve-is turned, the member 17 will also be turned.y

A handle 22 has a ring shaped part 23 encircling the outer end of kthe'sleeve and a set screw 211 passes through the part 28 into any one of a number of notches 25 formed in the sleeve whereby the handle can be adjusted on the sleeve to permit the lock to be` placed on doors of different thicknesses. v

As will be seen, by applying pressure to the handle 22, the sleeve will be turned to move the member 17 and this sleeve is `turned independently of the knoby stem 15 and the knob. stem can be turned withoutY .moving "the sleeve. An arm 26 is connected with the member 17 and carries a pin 27 which passes through a slot 28 formed in the rear part of the dead bolt so that the'rocking inovementct the member 17 Will'retract and project the dead bolt. This dead bolt is guided in its movement by means of a projection 29 formed on the 'casing engaging a slot 30 in the dead bolt. A dog 31 is pivotally arranged in the casing and has a projection 32 thereon for engaging either one of a pair ot notches 34 formed in the rear part of the dead bolt sothat the dog will lock the dead bolt in either its prof jected Vor retracted positions. Y

. `A spring 35 presses theV dog toward the deadbolt and the'tree end of `the dog is 1formed with a 'rounded enlargement 31 which engages the pin 27 on the arm ot'- the member 17 in such a manner that when the member 17 isY turned, the pressure of the pin Y the movement of the bolt;

:gages Y Vcertain extent by teV turningl of the member against'the rounded enlargementl will cause y'the dog to move outwardly against theaction ot its spring and thus, move the projection on the dog out of the .notch whichit en- After the bolt has been-.moved to -a 17 ,the pressure oit ythe spring on the dog will cause the rounded partof the dog to complete VThe detachable knob 16 is threaded to the stem 15 and the parts are locked together b-y `the set screw 16( and the striker plate 36 has a single. opening'37 therein to'receivejboth bolts, the upper wall oi the opening having i a projection 38 thereon for-entering the-top Vgroove 7 of the latch bolt. 7

Y -f VFrom the foregoingit will be Vseen that Teo the latchbolt canbe manipulated inthelordinary-manner from .either side lof the door through means or" the handles-'orf knobs 16,

but the dead boltlcan only beimanipulated` from one side otfthe door by turning theV from that side oi' the door which is loppositeV the side on which the dead bolt manipulating means are placed.-

As before stated, by making the latch bolt in two portions which are detachably connected together, the forked part can be reversed so that the dead bolt manipulating means may be placed on either side or"v th v door. i l

v It is thoughtl trom the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be tion and arrangement oitl the severalparts,

provided that such changes :tall within the scope of the appendedclaims.r
