WINDOW FASTENER Filed June 5, 1951 WML.

A Home y Patented May 10, 1932 iJNITEn STATES JOSEPH THOS. D'AWICKI, JR., OF JERSEY CITY, JERSEY WINDOW FASTENR Application led June 5,

The present invention relates to new and useful improvements in builders hardware, and more particularly it pertains to a new and improved form of window lock.

It is one of the objects of the present invention to provide a new and improved window loclr which will securely hold two sliding sash members against movement relative to each other.

A further object of the invention resides in the provision of a device of the aforementioned character which will automatically move to open position from locked position when properly operated.

It is a further object of the invention to provide a window lock which will prevent operation to released position bythe insertion of a tool between the meeting rails of a window sash.

With the above and other objects in view which will become apparent as the nature of the invention is better understood, reference will be had to the accompanying drawings, wherein:

Figure 1 is a transverse sectional view taken through the meeting rails of two window sash and showing a lock constructed in accordance with the present invention in its closed position,

Figure 2 is a horizontal sectional view showing vthe lock in section, and the meeting rails in top plan, and;

Figure 3 is a detail perspective view of the loch, the loclrbeing shown in its re` leased or open position.

Referring' more particularly to the drawings, the reference characters 5 and 6 designate the meeting rails of an inner and `outer window sash respectively.

A lock constructed in accordance with the present invention, preferably includes two housing members 7 and 8 which may be formed of any suitable material such as sheet metal and which are secured to the meeting rails of the outer and inner sash 6 and 5 respectively. The housings 7 and 8 are secured to their respective sash by means of screws or he like 9 which preferably pass through the housings near 'the ends thereof.

Pivotally connected as at 10 to the housing 1931. Serial No. 542,404.

7,'there is a swinging member 11 whichmember has a right angular extension 12 provided with a pair-.of'spaced openings 13 "as best' illustrated in Figure 3. 'The pivotal pointv Y of the member 10 consists of'a rodla mounted 55rk in an opening 15 inthe top wall of the housing 7 andsu'rrounding the rod, and having one end 16 engaging the member lO'and the other end 17 engaging the housing, there, is a coil spring V18 which tends to holdv theV 6o swinging memberl() in its yupright oropen position. j Y f The housing 8 is provided in its u'pperwall with a slot or the lilre 2O which is adapted to receive 'the right angular extension12 of 65 the member l1() when the-latter is moved to its locking or closing position. As best illustratedfin Figure 2, there are two guide rods 22 which extend transversely of the housing Vmember 8 and slidably mounted on these guide 70 rods, there is a cross bar 23 the latter being provided with openings to receive the guide rods 22. This cross bar 23 carries a plurality of projecting lugs or the like 24 which are adapted to pass through the openings 13 here- 75 toforementioned when the swinging member l0 is moved to its locking position and these members alsopass in the openings 25 in the front wall of the housing 8. A bowed spring 29 is'employed for maintaining the 8o cross bar 23 in its forward or locking position, and an operating member in the form of a shaft 30 having an operating knob 31 is attached to the cross bar 23 and projects through an opening in the front wall of the $5-- housing 8 to the exterior thereof.

From the foregoing it is apparent that with the parts in the position in which they are illustrated in Figure 3, it is only necessary to swing the member 10 about its pivotal point 90 against the action of the hinge 18 until the right angular extension 12 is positioned within the slot it being understood that the cross bar 23 will be depressed against the spring 29 to permit of this movement. After this has 9*? been done the member 23 is released `and the spring 29 forces the projecting lugs 24 into the opening 13 to lock the member in its closed' position.

While the invention-has been herein illustrated in a preferred form, it is to be understood that the same is not to be limited to the construction herein shown, and that it may be practiced in other forms Without departing from the spirit thereof. Y

Having thus described the invention, what is claimed as new and what itis desired to secure by Letters-Patent ofthe United States, 1s:

A lock for windows comprising in combination with two window sash,` a housing member carried by the meeting rail of each sash, a pivoted member carried by one ofv l said housing members, a right angular extenf sion on said pivoted member, said right angular extension having a. plurality of open- V ings therein, a slot inone of the walls of the other housing,said slot adapted to receive the right angular extension of the pivoted mem-A ber, andmeans for engagement with the openings in the right angular extension, of the pivoted'member toflock it inthe housing, said last; mentioned means comprising a sliding bar, and a.` plurality ofA projections on said sliding bar for entrance into the openings of thepivoted member and openings in the sidel wall of the housing in which it is mounted, and a springfor moving said bar into locking position.

In testimony whereof I aiX my signature.
