ZGlaims. (01.29am). T T T TT T This invention relates to improvements in window sashlocks, and an object of the invention is to provide a lock of this character which may the following description taken in connection with the accompanying drawings wherein:
Figure lis a perspective view illustrating the application of the invention.
Figure 2 is a longitudinal sectional view taken through a window structure further illustrating the application of the invention and with both sashes in an openv position and secured thereby through the medium of my improved sash lock.
Figure 3 is a perspective view of the sash lock.
Figure 4 is a perspective view of the stationary body plate or member, and:
Figure 5 is a similar View of the sliding body plate or member forming part of the lock.
Referring more in detail to the drawings it will be seen that in the preferred embodiment thereof the improved sash lock comprises a pair of complemental body plates including a relatively stationary body plate 5 and a slidable body plate 6.
The body plate 5 is provided at opposite side edges thereof with integral guide channels I which accommodatethe side edges of the sliding plate 5.
For shifting the plate t relative to the plate 5, and for securing the plates 5 and ii at the desired position of adjustment, there is provided an ad-. justing screw. l2 which at the head-equipped and I3 thereof is rotatably accommodated within an T opening l4 provided thereforin a flange l5 prohead-equipped, end It the screw I2 is provided with a removable collar lfi' that is disposed on the shank of the screw at the side of the flange l5 opposite tothe head I3 so as to coact with thehead for holding thescrew properly engaged 1 in the opening l4 for rotative movement of the screw, at the same time holding the screw against longitudinal movement through the opening M. i The threaded shank portion of the screw [2 has threaded engagement with the threaded opening in a boss I'I formed integral on the plate 6 at one end edge of the plate. Thus it will be seen that by turning the screw [2 in the proper direction plate 6 may be projected or retracted relative to the plate 5 for moving the jaws 9 toward and away from the jaws 8 for clamping the lock in position extending across the groove for the lower sash or for releasing.
the lock for removal from said groove.
Pivotally mounted on the plate 6 are a pair of complemental sash-engaging and locking jaws |8-I8. Adjacent one end thereof the jaws l8 have overlapping portions that are apertured and accommodate a pivot bolt I 9. At said end the jaws I8 are also provided with angular extensions 20 that serve as finger pieces or handles for manually manipulating the jaws.
At the opposite ends thereof the jaws l8 are ving thereto of the ends of a coil spring 24 that normally act to urge the ends 2| of the jaws towards one another. Movement of the ends 2! of the jaws towards one another in response to the action of spring 24 is limited through the 'medium of a stop 25 struck out from the plate 6 as shown.
The device is placed in one of the grooves for the lowersash and in a position where it is desired to stop upward movement of the upper end of said lower sash. The head H of the screw I2 is turned to cause the jaws 8 of plate 5 to engage the outer face of the stop strip ID and the jaws 9 to engage the inner face of the parting strip l0 so as to hold the device extending across the groove between said strips and while the 5 screw is being turned the members l8 are held in spread apart position so that their ends 2i do not project beyond the adjacent end of the plate 6 and will, therefore not engage the upper sash.
After the device is put in position these members 5 [8 are released so that their ends 2| will engage parts of the upper sash.
Thus the lower sash can only be raised to a position where its upper end will engage the device and the upper sash, if partly open, cannot be raised or lowered as the ends 2| of the members "3 will prevent movement in either direction of the upper sash for when the sash is moved in one direction one of the points 2! will dig into the frame member of the sash and when moved in an opposite direction the other pointed member 2| will dig into the sash.
Having thus described the invention what is claimed as new is:
1. A sash lock comprising a pair of plates one slidable on the other, a pair of jaw members on each plate for engaging side walls of a groove bridged by the plates, a screw rotatably carried by one plate and the other plate having a threaded hole therein forreceiving the screw, said screw when turned moving one platev relative to the other, guides on one plate receiving portions of the other plate, a stud carried by one plate, a pair of elongated members having overlapping intermediate portions pivotally supported by said stud, finger engaging parts on the inner ends of said elongated members, the other ends of said members having cutting edges thereon and said other ends normally projecting from the adjacent end of the stud carrying plate but said ends moving inwardly of said edge when the elongated members are spread apart at their outer ends and spring means for normally holding the said outer ends adjacent each other.
2. A sash lock comprising a first plate having guideways on its side edges and a flange at one end and jaw members at its side edges adjacent said one end, said jaw members extending in a direction opposite to the flange, a second plate slidably arranged on the first plate and having its side edges engaging the guides, a lug on the inner end of the second plate having a threaded hole therein, a screw rotatably supported by the flange and engaging the threaded hole, said second plate having jaws extending from its side edges, said jaws lying in planes which are inwardly of the planes of the first-mentioned jaws and the first plate having slots in its side por tions placed inwardly of the guides for receiving the jaws of the second plate when the plates are moved toward each other and means carried by the second plate forming stop means for an upper sash, said plate being adapted to bridge a lower sash guide groove in the Window frame with the jaws of the two plates engaging side walls of the groove, whereby the plates form stop means for the lower sash.
