MORRIS SUBBERfOF PHILADELPHIA, PENNSYLVANIA.

WINDOW AND DOOR LOCK.

Application filed May 25,

To all whom t may concern.:

VBe it known that I, MoRnIs SUBBER, a

' citizen of the United States, residing in the Y cutcheon'employe'd.

city andV county of Philadelphia, State of Pennsylvania, have invented a new and useful `I/Vindow and Door Lock, of which the following is a specification.

My invention consists of a device adapted to lock awindow or door, the same being effective in operation, of simple and inexpensive construction. and easily operative, as will be hereinafter set forth.

The invention is satisfactorily illustrated inthe accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit vorscope of the claims.

Figure l represents a perspective lview of a windowlock or fastening embodying my invention.

'.Fig. 2 represents a longitudinal section thereof on an enlarged scale.

Fig. 3 represents a side elevation of a detached portion thereof.

Fig. 4 represents an elevation of an es- Fig. 5 represents a side elevation of certain members in separated condition and on an enlarged scale. i

Fig. 6 represents va partial front elevation and a. partial longitudinal section of a door lock'or fastening embodying my invention.

Fig. 7 represents a top or plan view partly in section of the door lock or fastener lembodying myinvention, a portion of the door and ldoor j amb being also in section, the scale of said Fig.l 7 being slightly different from that of Fig. 6. i ,y

Similar numerals of reference yindicate corresponding parts in the figures.

Referring to the drawings. v1 designates a barrel which isV adapted to be located in the meeting rail 2, of the lower- Specicaton of Letters Patent.

Patented Sept. 6, 1921. 1920. serial No. 384,100.

near its outer end the escutcheon 5 which is secured to the inner side of the meeting rail 2 by the screwsV 6 or other suitable means, thus retaining said escutcheon and consequently the barrel firmly in position.

The socket 3 is provided with the face plate 7 which is secured to the inner side of the meeting rail 4 by the screws 8 or other `suitable means, thus retaining said plate and said socket firmly in position.

In the barrel is the movable or slidable bolt or plunger 9 the inner end of which com.- prises its head portion 10 which is adapted to enter the socket 3 and thus lock the sashes in fully closed position, it being noticed that the meeting rail 4 is provided with an additional socket 11 which may receive the head portion of the bolt and so lock the sashes in partly open position.

Within the barrel encircling the bolt 9 is the coil ,spring 12 whose ends are adapted to bear respectively against the inner face of the escutcheon 5 and the shoulder 13 on the head portion 10 of the bolt, the socket having centrally therein the rubber or other cushion 14 with which the contiguous end of the portion 10 of the bolt may contact and which may be compressed, thus more firmly retaining the bolt in the socket and preventing rattling thereof as well as the meeting rails of the sashes.

Extended from the cscutcheon and conscquently from the face of the meeting rail is the tube 15 in whose wall is the longitudinally extending slot 16, it being noticed that the bolt 9 is extended outside of the barN 'rel .so that a portion 17 of the saine fully occupies the tube 15 and is slidable therein. Connected with the said extension at a certain distance from its outer terminal is thel pin 18 forming a finger piece for the operation of the bolt, as will be hereinafter referred to. In the wall of the slot 16 adjacent to the escutcheon 5 is the recess 19 which is adapted to receive the finger piece 1S on turning the bolt by the latter, thus retaining the bolt in the socket and consequently locking the sashes.

In order to prevent opening of the bolt by access to the same and tampering therewith from between the meeting rails or from any improper return rotation of the bolt, l employ the bent catch20 which is adapted to be connected removably with thel escutcheon 5 so as to extend outwardly therefrom and engage with the side of the iinger piece 18 to control the same when the latter occupies the recess 19 in the wall of the slot 16 oiE the tube' 15, thus preventing said finger piece from removal from said recess and conse quently preventing motion of the bolt from the socket 3 the compressed cushion 14 then causing the finger piece 8 to be pressed out wardly tightlyagainst said catch 20.

`The operation is as follows :-V Y y The pin 2O having been removed and the bolt 9 occupying its outermost position, the finger piece 18 having moved with the bolt through the slot 16 or' the extension 15, and the sashes having been 'ully closed, the bolt is pushed in by the nger piece so that its head portion enters the socket which piece has been grasped for the purpose. l'Vhen said 'finger piece reaches the recess 19 the bolt is turned say to the right by said piece so that it enters said recess and'said bolt has its Vhead portion 10 occupy the socket, thus locking the sashes, the spring 12 having been compressed as has been stated. Then to prevent improper return of the bolt, the pin 20 is connected with the escutcheon and so controls the nger piece 18 and consequently the bolt from movement, whereby the sashes remain locked.

When the sashes are to be unlocked the controlling pin 20 of the finger piece 18 is removed, when the latter is grasped and the bolt rotated by the same, say to the left, the

finger piece then leaving the recess 19 when' the bolt is drawn out by the {ingerpiece when the spring 13 is compressed, the head of the bolt then leaving the'socket and en tering the barrel, and so the sashes are unlocked. The finger piece may nowbe'turned with the bolt and inserted in either of the recesses 21 in the outer terminal oi' the tube 15 on opposite sides or said tube under the compression of said spring 12 whereby the tube is prevented from motion. The retaining catch 20 may be returned to the es,- cutcheonwhen the'device is in position lor the next operation of locking the sashes. The pin 2O is adapted to overhang the linger piece.18 so as to lock the latter and consequently the bolt, but in order to unlock the bolt said pin requires to be rotated so as to clear said finger piece when the latter is tree to be moved outwardly in the slot 16 of the tube 15 to withdraw the bolt from' the socket 3, but said pin 20 may be unscrewed from the escutcheon 5 and so entirely removed from the latter whereby it no longer controls saidpiece 18 when said piece may be returned into the slot 16 and moved out of the same carrying with it the bolt 9 for. the same purpose as above.

Thetube 15 comprises an outward eXtension of the barrel, and the bolt is suficiently long to occupy both said barrel and tube.

Y ln Figs. 6 and 7 I show the device applicable to a door to lock the same,the socketV 3 being fitted in the door jamb, and the barrel itted on the door 'frame adjacent to the j amb. A recess 22 is formed in the door at the inner terminal of the barrel to permitV the` play of the bolt and the linger piece 18. ln this case aface plate such as 23 is secured to the door in front of said Vrecess 22 Y Having thus described my invention-what I claim as new and ldesire to secure by Letters Patent, is
