Application July 3, 1946, Serial No. 681,284
My present invention relates to an improved forget-proof window lock and more particularly to the type of window lock or latch which is releasable manually to open the lower window sash and which is provided with tripping means for automatically setting the latch in looking position when the sash is lowered to closing position.
In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised but it will be understood that various changes and alterations may be made in the exemplified Structure within the scope of the appended claims.
In the drawings:
Figure 1 is a vertical sectional view of a window frame showing the latch in looking position.
Figure 2 is a similar view showing the latch unlocked.
Figure 3 is a horizontal sectional view at line 3-3 of Figure 2.
Figure 4 is a front elevational view showing the latch in locked position.
Figure 5 is a detail view of the latch mechanism; and.
Figure 6 is an elevational view thereof.
Figure 7 is a perspective view of the latch bar adapted to be mounted on the upper window sash.
Referring now to the drawings in detail, I have illustrated the window lock or latch of my invention as embodied in the window frame 2 having an upper sash 4 and a lower sash 6, each having a pane P.
A catch 8 having attaching holes l0 and an angular lug I2 is secured to the upper sash near the bottom thereof as illustrated.
The latch mechanism comprises a toggle arrangement including the base l3 having open vertical supports I4 and secured to the upper edge of the lower sash. A pin 26 pivotally supports latch I8 which is formed of substantially triangular shape and having a finger release 20 at one angle, a lock 22, at a second angle, and a trip 24 at the third angle.
A lever 28 depends from the latch and is formed with an open center 30 and a cross bar 32 adapted to engage the inner edges of the supports M. A collar 34 having spaced prongs 36 which engage on either side of the cross bar, is seated in the upper end of a coil spring 38 which is secured on the lug 40 on the base l3.
In operation, the finger release 28 is depressed to pivot the latch against the tension of the spring to place the trip 24 in operative position, and the lock 22 out of position. As the lower sash is elevated the trip 24 will abut the lug l2 1 Claim. (Cl. 292-498) on the upper sash and will as it passes pivot the latch l8 placing again the lock 22 in position to engage the lug l2 as the lower sash is lowered to close the window.
In so doing the lock 22 will ride over the lug against the tension of the spring without tripping or pivoting the latch to the point where the spring will retain the pivoted latch in off position, and if the lower sash is again subjected to upward movement the lock will abut the lug and prevent such movement until the finger release is depressed and the latch tripped.
The spring is so positioned on the base to press against the lever of the latch to permit relative movement of the latch against the tension of the spring to a certain point whereupon the toggle eiiect will follow and the latch will be set in position to be tripped as seen in Figures 2 and 5.
Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:
A window sash lock comprising a base having open vertical supports laterally spaced from one another, said base being adapted to be connected to the upper edge of a lower window, a latch pivotally connected between the vertical supports, said latch having a finger release extending at one angle, a lock finger extending at another angle, a trip projection extending at a third angle and a lever extending at a fourth angle, said lock finger and said trip finger being adapted to engage a projection on the upper window, said lever having lateral projections engageable with the edges of the vertical supports, a toggle spring, an inclined leg on the base connecting one end of the spring to the base and a collar on the opposite end of the spring having spaced prongs thereon to receive the lever projection, and said spring adapted in one position to urge the lever arm toward the upper window to retain the trip finger in its projected position and adapted in another position to force the lever toward the rear of the vertical supports to hold the lock finger in its projected position.
