'ion wmiiors a, kan? retain this position so long as thebolt 25 remains 1n closed position. By this means -the two sashes are locked together, and can jeetingend 26 0f thebolt 25 is forced iii-- wardly which removes the retaining Wall of thebolt 25 from thenotch 24 of thebolt 18, and releases the latter which is at once withdrawn from thekeeper 32 by the action of the spring 21.- IVhen the sashes are again to be locked in closed position the projectingend 19 of thebolt 18 is forced inwardly against thespring 21 which action moves thenotch 24 into position to be engaged by thebolt 25, which thus locks thebolt 18 in its projected posit-ion and within thekeeper 32.

The improved device is simple in construction, can be inexpensively manufactured, and applied to sashes of different sizes, and ell'ectually locks the sashes in closed position.

The casing and other parts may be oi any required size to adapt the device to sashes oi diifercnt sizes, and may be manufactured of any required material, or in any required ornamental shape.

Knobs are attached to the terminals 19-26 of the bolts 18-24 to improve the appearance.
