This invention relates to window latches Fig. 5 is another similar view and showing or fasteners and aims to provide a novel cona further modified form of latchbolt. structionin devices of the above mentioned Referring in detail to the drawings I aptype, whereby the upper and lower window ply a casing 10, to the upper rail 11 of the low 5 sashes may be automatically and securely window sash and a keeper 12, to the lower so locked by simple pressure of the thumb or rail 13 of the upper sash. The parts are prefw iii or on a linger piece forming a part of the erably applied by screws or other fastening con 'uetion and readily unlocked by madevicesl l. nipulating the said finger piece to partially The casing is open at the bottom and has turn a bolt member on its axis. end walls 15 and 16 the former preferably An object of the invention is to provide a having a squared opening 17 therethrough simple inexpensive device for accomplishing and the latter being formed with a circular the above results possessing features intended opening 18. c to obviate some of the objections'present inv Alatch bolt 19 operates in the openings just D the prevailing styles of construction for the described and is of round cross section for same purpose now in general use. 7 abouthalf of its length from its locking end Features of the invention are found in a asshown at 20, and terminates in a squared suitably formed casing adapted to be secured portion 21, which normally engages the to the upper rail of the lower window sash squared opening 17 and beyond the, squared 20 and a keeper plate adapted to be fastened to portion is another but shorter rounded por- 7 the lower rail of the upper sash said keeper tion 22 from which a radial pin projects, plate being provided with a central circular from one side, whichacts to limit the rotary opening having flared walls and side slots or turning movementof the boltlQ by concommunicating with said opening, the said tact with one of a pairof stop pins and 25 casing being provided with end walls, one 25. A head QGQhaVing a finger piece 27 is wall having a circular opening and the other fixed to the outer end of the bolt 19, by which a squared one, through which a bolt, having said bolt is manipulated and a cross pin 28 round and square portions is slidable, means is carried by said bolt near the locking end being provided to automatically rotate said thereof and which normally is drawn against 30 bolt through a limited are when a round pen the casing 10 by the urge of aspiralspring ion is in registration with a squaredopen- 29, having one endheld bya screw 29threading of the corresponding end wall of the ed into the end 16 of thecasing and the other casing. end held by a screw 80 threaded into the bolt The invention has for its further objects to 19, This spring is normally sli htl C n which will be more clearly defined in the folis also charged torsionally to automatically lowing detailed description.

It should be understood that the squared portion 21 is engaged. by the squared opening 17 at all times except when the latch bolt is in its rearmost position so that no turning movement can take place only at that time and then said movement is limited by the stop pins 2% and v In Fig. i I show ainodihed form in which I may provide the end 1501- the casing with a tongue and the shaft may 'have'short grooves 35 arranged at'90,the spin ofthe latch bolt taking place when a circumferential groove registers with the tongue In Fig. 5, I show another form in which the shaft 19 may have a short rib or feather 3'7, slid'able in one or the other of grooves 38 in wall 15 of the casing, the spin oithe latch bar taking place when the rib or feather clears the said well in its slidingmovement.

3. In a window latch, a housing and a keeper, said housing having end walls, one provided with a circular opening and the other with asquared one a bolt operable in said openings, a stop pin'on one end of said bolt and a securing ,pin on the other, and means for automatically causing the bolt to turn whenthe securing pin thereon has been passed through said keeper to secure the parts, attached one end to the housing and the other end to the bolt.
4:. A window latch comprising a housing and a keeper, said keeper being provided with a central opening and communicating slots, said housing having end walls, one having a round opening, the other a squared one, a bolt operating in said openings and having rounded portions and a square portion normally engagin the said square openingsaid bolt having a finger piece, a stop pin and a securing pin, and means for causing said securing pin to engage said keeper when it passes the opening therein.
5, A window latch comprising a housing and a keeper, "said keeper being provided with a central oponingand communicating slots, said housing having end walls, one having' a round opening, the othera squared one, a bolt operating in said'openin s and having rounded portions and .a square portion nor mally thesaid square opening, said bolt having a finger piece, a stop pinand a securing pin, andmeans tor-causing said securing pin to engage said keeper when it passes theopeningtherein, said meanscoinprisinga longitudinally tensioned and torsionally charged spring.
In a window latch, a housing and a keeper, said housing having end walls provided with openings, a bolt operable in said openings, a stop pin on one end of said bolt and a securing pin on the other, means on said bolt and in one of said end walls associated with its opening, adapted to prevent the passing of the bolt except in a position determined by said stop pin, and means for automatically causing the bolt to turn when the securing pin thereon has been passed through said keeper to secure the parts.
