Application filed March 18, 1915. Serial No. 15,330.

To all whom it may concern: I

Be it known that I, VVILLIAMF. BARGER, residing at Nor-wood, Hamilton county, State of ()hio, have invented certain new a-nd useit'ul Improvements in Sash-Locks, of which the following is a clear, full, and exact description, attention being called to the drawing which accompanies this application and forms a part thereof.

This invention concerns locks for locking windows with sliding sashes and where the locking is accomplished by lockingtwo sashes of a window to each other by complementary locking members which are positioned on the meeting rails'of the sashes, one member on the rail of each sash.

It relates more particularly to that type of locks in which the sashes are 'locked' to each other, not only in the usual normal position, when both sashes are closed, but

also in positions with either or both oi th'em partly open. 3 1

The invention consists of certain simplifications of the construction of the particular means whereby the sashesare locked to each other in closed as well as in partly open positions. This construction ishereina-fter described and pointed out in the claim as well as illustrated inthe accompanying drawing in which:

Figure 1. hows in cross section'the meeting rails of the two sashes of a window in a position which they occupy with reference to each other when said sashes are closed 3' the complementary members of my lock are shown in disengaged or unlocking position. Fig. 2. in a similar view shows the locking members engaged for locking the sashes to each other in their closed position. Fig. 3. in a similar view shows the sashes locked to each other with one of the sashes moved with reference to the other one. Fig. 4:. is a top view of the parts shown in Fig. 1. Fig. 5. is a sectional top-view of the parts shown in Fig. 3 and as they appear below line 5-5 indicated in said figure. Fig. 6 is an elevation of the parts shown in Fig. 3, and as viewed from the right of said figure, or what would be the same, from the inside of the window.

In the drawing, letter A, indicates the lower or meeting rail of the outer, or upper sash, and letter B indicates the upper or meeting rail of the inner or lower sash. The lock consists substantially of an upright, crescent-shaped member or locking cam C,

'Figs. 1, Q'and 4,

' provided with a narrowing slot 8,and-having a fiat attaching flange 9, whereby, by means oi a pivot pin 10, it is mounted upon a base 11 on which it may be rotated by 'means ofa handle 12. Base 11 is provided with flanges 13 whereby it is attached upon the meeting rail B of the lower'sash.

Complementary keepers are adapted to coact with the cam, they being in form 71 of elongated buttons lt, provided between their ends with shanks 15 whichproject from a keeper bar, consisting of 'a short member 16 and of a longer member 17 arranged at right angles to each other. From this keeper bar at the apex of the angle thereof, and at right angles to the jects a journal 18 fitted to a bearing 19 provided with flanges 21, whereby it is attachedto the meeting rail A, of the upper sash. The keeper bar may be adjusted in its bearing 19 so that either the short member 16 occupies an upright position at right angles to the meeting rail and as'shown in or that the longmember occupies such a position and as shown in Figs.. 3, 5 and 6. these members, by its contact with the meeting rail upon which the bar is mounted,gdefines the proper position of the other mem her with reference to locking cam C, to permit this cam to enter into locking engage- -ment with one of the keeper buttons on the One of these buttons is pro-. vided on the short member of the bar-"and in a position to permit it to be engaged by keeper bar.

Locking en- Figs. 3, 5 and 6 and one plane of said angle, there pro- In either case one of of the sashes is moved until in proper position to permit cam C to effect locking engagement with one of the keeper buttons on this member of the keeper bar. A series of such buttons, suitably spaced are provlded on this longer member 17 of the keeper bar so that the sashes may be locked in several correspondingly open positions. When the complementary locking members areso engaged, shank 15 of the buttons occuples slot 8 in looking cam C, and the button itself, being in each case parallel to the keeper,

bar extends over both edges of the slot and occupies a position inside of the cam, that is in contact with theconcave part thereof, both above and below the slot therein. By reason of the eccentricity of said cam and its hooked engagement with the button, the engaged parts are closely drawn toward each other, so that the meeting rails are correspondingly drawn into close contact whereby a tight closure is effected and rattling of the sashes prevented. When the sashes are locked to each other in the positions as shown in Figs. 3, 5 and 6, they may be moved as a whole, so that the opening obtained by their relative adjustment, may be either above. the upper sash or below the lower sash, or the position of the sashes may be equalized so that an open space may be had below as well as above the sashes. The locking engagement is a positive one and absolutely secure against tampering from the outside because the shank of the button occupies the narrow end of the slot in the locking cam which it cannot leave because the button itself hooks over the lower as well as over the upper edge of the slot in the cam. A knob 22 is provided at the end of the longer member 17 of the keeper bar whereby this bar may be utilized as a lift to move the sashes. Base 11 is hollow and may be occupied by a usual friction spring which, by engagement with pivot 10 inside of said base, serves to yieldingly hold looking cam C in either locked or unlocked positions. This expedient is common in sash locks and no novelty is claimed therefor.

Having described my invention, I claimas new:

In a lock of the type explained, to positively lock the complementary sashes of a window to each other, the combination of an eccentric locking member mounted upon the meeting rails of one of the sashes and comprising a handle and an upright, crescentshaped locking cam which has a horizontally extending slot open at one end and narrowing toward its other end, a keeper bar formed to integrally contain a short and a long member arranged at right angles to each other and provided with a series of shanks projecting toward the locking cam and adapted to occupy the narrow end of the slot therein, said shanks having elongated locking buttons which project from each side thereof parallel to the keeper bar, a journal projecting from this bar at the apex of the angle where its members diverge, and a bearing for this journal whereby the bar is adj ustably mounted upon the meeting rail of the other sash and so that either of its members may occupy a position in which it extends over the meeting rail and in contact therewith and which position places the other member of said keeper bar in a position which permits the locking cam on the other sash to enter positive locking engagement with the keeper bar by receiving the shank of one of the locking buttons thereof in the narrow end of its slot so that said locking button occupies the concave side of the cam with one part of the button hooking over the lower edge of this slot in said cam and with the other part of the button hooking over the upper edge thereof.

In testimony whereof, I hereunto affix my signature in the presence of two witnesses.
