June 30, 1936. w. H. CREBER CASEMENT LATCHING DEVICE Filed June 1, 1935 IN VENTOR.

Patented June 30, 1936 UNITED STATES PATENT oFFieE GASEMENT LATCHING' DEVICE William H. Creber, Los Angeles, Calif. Application June 1, 1935,Serial No; 24,534 b 7 Claims. (01. 16-144) s to Figuresv 1 and 3, ll) designates a casement This invention relates to an adjustable latch for hinged members, herein designed for use in connection with a casement, but adaptable to general use.

The principal object of the invention is to provide a simple, inexpensive and positive latch for ad-justably latching a casement at its hinge from moving relative to its jam or frame.

Another object of the invention is to obtain adjustable latching of a casement by means of a bolt slidable in one direction toopen the latch and slidable in the other direction to close the latch, but not requiring turning of the bolt to either latch the easement or unlatoh it.

Another object of the invention is to provide a casement latch adapted to coact with. the casement hinge; which will normally rest in a position positively latching the casement from moving; which will grip both wings of the easement hinge in effecting the latching function, and which will release the wings of the hinge tomove freely relatively by movement of the latch member in one direction and again latch the hinge wings from relative movement by movement of the latch member in the opposite direction.

Another object is to provide a casementlatch adjustable in a considerable plurality of positively held positions, and one that is void of springs, snaps, lock screwsor any of the numerous forms of latching instrumentalities employed in window latches.

Still another object is to provide. a casement latch for installation on the inside and particularly in close proximity to the rabbet between the sash and frame, in which location it is most inaccessible from the outside and therefore unusually efiective to prevent further opening of the casement from a partially open ventilating position.

And still another object of the invention is to provide an adjustable casement latching device which lends itself to the obtaining of both adjustment and latching functions by means 7 of a single slidable latch member adapted to be moved in a plane parallel to the axis of the hinge to obtain the advantage of gravityfor holding the latch member in its latching functioning position.

Q'ther objects and advantages will appear in the attached specification and claims.

Fig. 1 is an elevational view of one form of the presentinventi'on showing the combined. slide bolt and latch secured to a sash slightly ajar relative to: the jam- Fig. 2 is another elevational view showing a modified form of the present invention also secured to. a sash slightly ajar relative to the jam.

Fig. 3 is a plan view looking downward on the axis line of the easement hinge and showing the form of the present invention illustrated by Fig. 1.

Referring to the drawing and. for the present adapted for swinging motion relative to a jam or frame indicated at H. Supporting the casement I0 for horizontal swinging motion frornthe frame II is a hinge 12 having two wings or leaves l3 and, the leaf I3 being secured to the easement I0 and the leaf l4 being secured to the frame or jam II. This hinge is of the conventional form and is jointed at its leaf axis by the usual pin l5. It will beobvious that this hinge ofiers two exposed bar edges l6 and I1 comprising the top or bottom edges of the two leaves l3 and'l4 'disposed between the axis of the hinge and the'oute'r portions which engage the sash and frame, re-

spectively. Since these exposed and coincident bar portions I6 and I! extend radially from the hinge axis, and swinging toward and fromeach other, upon closing and opening the casement H), the two upper or lower edges I6 and ll therefore would accommodate a toothed, recessed or notched radius disk or mushroom shaped portion of the latch member I8 when raised and lowered intoengagement with the upper or lower COlIlCl-r dent edges l6 and ll of the hinge leaves l3 and [4, whereby the hinge is latched and the casement latched accordingly. Hence the present invention is found to include a bolt or slide bar part [9 slidably mounted preferably by a guide plate or base member 20 provided with guides 2! and 2| receiving the slide bar part l9 and which is secured to the casement (sash) l0 and which slide bar part I!) ispreferably formed to include an integral and outwardly off-set portion [8 provided with irregularly spaced notches 2| for engagement with the edges l6 and ll of the hinge wings l3 and I4.

It will be seen that if the invention is installed vertically, above the hinge, the slidable bolt [9 and flanged disk l8 will constitute a gravity inclined member which will maintain in any selected position the easement Ill from moving relative to the jam orframe.

To change the position of the casement, it will be obvious that this simple latch only requires that the bolt [9 beraised, the casement moved to the desired position, and the bolt l 9 again moved into engagement with the hinge leaves 13 and. M.

Referring now. to Fig. 2, a modified form of making the slidable bolt and latching portion is shown. The numeral 22 indicating this main part of the invention consisting of a ribbon of metal is bent to suffice therequirements of both the slide bolt I9 and the notched portion l 8. All other parts being the same as illustrated in Fig. 1 are indicated by the same numerals. The construction' of the modified form of the invention illustrated in Fig. 2 differs from the construction. illustrated in. Fig. 1, principally, in that a bar stock of substantially one size from end to end is used for the bolt and projecting latching portion l9 and I8, thus integrally forming the movable latch member. The stock being twisted at substantially right angle to the bolt portion l9 and from the angularly projecting juncture point with the bolt portion l9 being twisted spirally to a central point so as to provide the latching portion I8 in which the series of recesses 01' notches 2| are irregularly spaced for cooperalation While I have illustrated preferred forms of the present invention, it will be understood that varrious changes may be made and other forms employed without departing from the spirit of the invention as set forth in the appended claims,

Thus it will be seen that I have provided a singular adjustable and positive latching device which is simple, inexpensive of manufacture, easily installed and novel particularly in its making use of the established hinge found on the easement to complete an adjustable latching apparatus therefor.

I claim:
