SASH 0R WINDOW FASTENER.

Specification of Letters Patent.

Patented June 3, 1919.

Application filed February 18, 1919. Serial No. 277,857.

To all whom it may concern:

Be it known that I, EMANUEL KnUsnR, S11, a citizen of the United States, residing at Palmyra, in the county of Burlington, State of New Jersey, have invented a new and useful Sash or Window Fastener, of which the following is a specification.

My invention consists of a sash or window fastener comprising a plurality of locking members, whereby sashes will be effectively fastened or locked and the fastener is rendered incapable of being released from without through the joint of the meeting rails of the sashes.

V The invention is satisfactorily illustrated in the 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 or scope of the claims.

Figure 1 represents a perspective view of a sash fastener embodying my invention.

Fig. 2 represents a transverse vertical section on the line 22 Fig. 1.

Fig. 3 represents a plan View of the fastener in open condition.

Fig. 4 represents a plan view of the fastener in partly closed condition.

Fig. 5 represents a plan view of one member of the fastener.

Fig. 6 represents a plan view of the other member of the fastener.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings 1 designates a portion of the meeting rail of the upper sash of a window, and 2 designates a portion of the meeting rail of the lower sash thereof, both as usual.

3 designates a face plate which is secured firmly to the top of the meeting rail 1, and on the same is connected by the pivot 4, one end of the primary latch 5 which may be turned on said face plate 3 parallel with the meeting rail 1, as in Fig. 3, or turned at a right angle thereto as to overhang the meeting rail 2, as in Figs. 1, 2, and 4, said latch consisting of a bar of metal, or other suitable material having in its side the in turned recess 6.

7 designates a face plate which is secured firmly to the top of the meeting rail 2 and from the same rises the headed stud or post 8 which is adapted to be engaged by the walls of the recess 6 of the latch 5.

7 Connected with the free end of the latch 5 by the pivot 9 is the auxiliary latch 10 which consists of a bar of metal or other suitable material having in its side the circular recess 11 whose wall is adapted to engage the shank of the stud. On the free end of said auxiliary latch 10 is the thumb piece 12 whereby said latch may be readily operated. in opposite direction.

On the pivotal end of said latch 10 is the downwardly extending lip 13 which when the latches are in position shown in Figs. 3 and 5 are adapted to abut the shoulder 14 on the free end of the latch 5 as a stop limiting the opening motion of the latch 10, asshown in said Figs. 3 and 5, said lip 18 being also adapted to abut the shoulder 15 on the free end of the latch 5 opposite to the shoulder 14 as a stop limiting the closing motion of said latch as shown in Fig. 1.

When the sashes are unfastened or unlocked, the latches are continuous of each other in the same direction, as in Fig. 3, both occupying the meeting rail of the upper sash whereby the meeting rails may pass each other freely in the raising and lowering of the sashes.

In order to fasten the sashes, the latch 5 is turned to right angular position over the meeting rail 2, as in Fig. 1-, and the recess 6 receives the stud 8 causing the latter to en gage the walls of said recess and so primary fasten or look said latch. Then the latch 10 is turned over the latch 5 when the recess 11 receives the stud 8, causing the latter to engage the walls of said recess 11, and so fasten or look said latch 10, both latches thus being fastened or locked the same being true of both meeting rails, and consequently of the sashes, it being noticed the two latches cannot be raised by any implement inserted through the joint of the two meeting rails as the head of the stud 8 overhangs the latch 10 around the recess 11 while said sides of said latch 10 is rendered inaccessible by such implement owing to the barrier formed by the sides of the lower latch 5 in the path of such implement to have access to the sides of the upper latch 10, and so the latter is guarded from below whereby it cannot be moved say to the left to disengage it from said stud, nor can the latch 5 be moved say to the right owing to the locking action of the latch and stud '8 on said latch 5, it being noticed that when said latch 10 is closed the wall of the recess curves somewhat aroundthe shank of the stud 8 and so embraces it sufiiciently to take firm hold thereof to prevent improper movement of the latch from said stud which latter is common to both recesses 6 and 11,

and so is a common fastening for both latches.

Should an attempt be made to move the latch 5 to the left, the stud 8 stationary on the meeting rail of the lower sash will resist the same, and as the right side of the upper latch 10 is guarded by the right side of the lower latch an implement cannot reach said right side of the upper latch especially as the latter is made preferably narrower than the lower latch.

W hen, however, superior force is exerted on the upper latch to the left, said latch is moved from the stud 8 and disengaged therefrom, as in Fig. 4, then the lower latch can be moved to the right disengaged from the stud 8 and then both latches maybe swung clear of the meeting rail of the lower sash and placed on the meeting rail of the upper sash as in Fig. 3, when the sashes are unfastened or unlocked, and so may be raised and lowered as usual.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent, is

1. A fastener for window sashes consisting of a plurality of latches, means for pivotally connecting adjacent ends of said latches, means on one of said latches adapting it to be movably mounted on one of the meeting rails of a sash, said latcheshaving registering recesses therein, and means connectible with the other meeting rail with which both latches are adapted to have a common engagement in said recesses in the locked condition of the fastener.

2. A fastener for window sashes consisting of a plurality of latches, means foripivend a lip which is adapted to engage either 7 of said shoulders in the diflerent positions of said upper latch.

3. A fastener for window sashes consist-- ing of a plurality of pivotally connected latches, each having a recess therein,on'e of said latches being adapted tobe mounted movably on a meeting rail of one of the sashes, and a post-like member connectible with the meeting rail of the other sash, said post being adapted to have both of said latches lockingly engaged therewith in said recesses thereof.

4. In a fastener for window sashes, a plurality of latches, the same being pivot-ally connected, and one of the same being adapted to be pivotally mounted on oneof' the meeting rails ofa sash, and a post-like member adapted to be connected with the meeting railof the other sash, said latches being adapted to have said post like member enter the same and thereby interlock both latches.

5. In a fastener for window sashes, a plurality of latches, the same being pivotally connected, and one of the same being adapted to be pivotally mounted on one of the meeting rails of'a sash, and a post-like member adapted to be connected with the meta ing rail of the other sash, said latches being adapted to have said post-lil'r'e member enter the same and thereby interlock both latches, said post like member having a head which is adapted to overhang the contiguous latch.
