Description
Feb. 21, 1939. J. K. COOPER WINDOW-SASH LOCK Filed March 25, 1938 Inventor /0Z11 K (be nez" and . Attorneys Patented Feb. 21, 1939 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to closure fasteners and more particularly to looks for use in conjunction with window sashes for locking the top and bottom sashes of a window at the desired position of adjustment.
An object of the invention is to generally improve upon window sash locks of this general type; and the invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawing wherein:
Figure 1 is a perspective view illustrating the invention, partly broken away, and
Figure 2 is a perspective view of a bolt.
Referring to the drawing by reference numerals it will be seen that in accordance with the present invention there is provided a keeper plate 5. The plate 5 is substantially channel-shaped and has the sides thereof provided with outstanding apertured attaching flanges 6 through the medium of which and screws or other fastening elements I said plate is secured to one of the members, 8, of the top window sash 9.
Plate 5, as shown, is provided with a vertical series of notches I0, the lower sides of which are on an incline as shown in Figure l, and a series of apertures II arranged in alternation to the notches II] and properly positioned with respect thereto.
Carried on the top member I2 of the lower sash I3 is a bolt casing I4 which may be of any suitable construction and which in the present instance is shown as being opened at opposite sides thereof and at said sides provided with outstanding base flanges I5 through the medium of which and screws or other fastening elements IS the casing is suitably secured to the frame of the lower sash.
Adjacent one end thereof the casing I4 is provided with a transverse partition I 1 as shown.
The opposite end walls, and partition ll of the casing are apertured to slidably accommodate an upper keeper bolt I8 and a lower locking bolt I9.
The bolt I8 is provided at one end thereof with a conventional bolt head 20 that is engageable with a selected notch ID in a manner to positively preclude raising of the lower sash I2 relative to the upper sash 9, and a lowering of the upper sash 9 relative to thelower sash I2; while at the same time permitting sash I2 to be lowered relative to the sash 9 as found desirable.
The locking bolt I9 is engageable with a selected one of the openings II for positively securing the sashes 9 and I3 against being raised or lowered relative to one another and thereby positively securing the said sashes at the desired position of adjustment.
For locking the bolt I8 in either of two positions there is pivotally mounted on one end wall of the casing I4 a locking dog 20, and the knobequipped end of the bolt I8 is provided with a notch 2I with which the dog 20 is engageable to lock the bolt I8 in retracted position against the action of spring 22; while the bolt I8 is also provided with a notch 23 with which the dog 20 is engageable for locking the bolt I8 in projected position.
For locking the bolt I9 in retracted position against the action of spring 24, there is slidably mounted on the aforementioned end wall of the casing I4 a locking plate 25 that in its lower edge is provided with a notch 26 adapted to accommodate the head-equipped end of the bolt I9 with the upper edge of the notch engaging in a transverse notch 21 provided in the bolt I9.
To look the bolt I9 in projected position said bolt is provided with a transverse notch 28 with which the upper edge of the aforementioned notch 26 in plate 25 is engageable as shown in Figure 1.
Plate 25 is slidably mounted on the aforementioned end wall of the casing I4 through the medium of a headed stud 29 mounted on said wall and engaging a vertical slot 30 in plate 25 as clearly shown in Figure 1.
For automatically releasing the bolt I8 when the latter is in a retracted position, and the sashes 9 and I3 are in extreme closed positions, there is provided a trip rod 3I that is rotatably supported by the partition I! and end walls of the casing I4 and this rod 3| at one end thereof is provided with an arm 32 engageable with the dog 29 to swing the latter upwardly out of engagement with the bolt I8, upward movement of the dog 20 being limited by a suitably provided stop pin 33. At the relatively opposite end thereof trip rod 3| is provided with a crank arm 34 that, as the sashes 9 and I3 move into extreme closed positions, engages a trip lug 35 provided on one side of the bar 5 adjacent the lower end of the bar and in a manner clearly shown in Figure 1 whereby to rock the rod 3| in a direction to cause the arm 32 of said rod to engage the dog 20 to lift the latter upwardly out of engagement with the bolt I8 thereby releasing the bolt and permitting the latter, in response to the action of spring 22, to be projected in a manner to engage the head 20 thereof with the lowermost notch ID for positively locking, in conjunction with the bolt I9, the sashes in this extreme closed position.
From the foregoing it will be seen that I have provided a window sash lock which will operate efliciently for locking two sashes at the desired position of adjustment relative to one another so that the sashes may be locked in either fully closed position or in partially open position as found desirable.
It is thought that a clear understanding of the construction, utility, operation and advantages of an invention of this character will be had without a more detailed description.
Having thus described the invention what is claimed as new is:
A sash lock of the class described comprising a bolt casing, a spring pressed bolt slidably arranged in the casing for engaging a keeper memher when projected, said bolt having an end, opposite the keeper engaging end, projecting from the casing, a knob on the projecting end, said projecting end having spaced notches in its upper edge, a latch lever pivoted to the casing and dropping by gravity into engagement with a notch when the bolt is in position with a notch under the latch lever, a rod passing through the casing and having one end bent for engaging with the latch lever and its opposite end cranked to engage a stationary cam when the sash is in lowered position and causes the rod to partly rotate whereby the bent end of the rod will lift the lach lever out of a notch.
