- WINDOW-SASH LOCK Specification of Letters Patent.-
Patented June 22, 1909.
Application filed December-21, 1908. Serial No. 468,667.
To all whom it may concern:
Be it known that I, F REDERIOK D. RAT
FORTH, a citizen of the United States, residfollowing to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it ap ertains-to make and useth'e samef he object of the invention is to provide a simple, cheap, durable, and efficient sash lock which may be employed to positively locka window in open or closedposition and which will revent the lock being operated and the window opened from the outside.
In the accompanying drawings, Figure 1 is a vertical elevation of a window having the improved lock applied thereto, Fig. 2 is a fragmentary View: of the upper and lower sashofa window showing the lock in closed position, Fig. 3 is an elevation of the plate member of the lock Fig. 4 is'a horizontal section thereof, Fig. 5 1s a plan view.
of the bo'lt, and Fig. 6 is a longitudinal section throughthe bolt mechanism.
Referring .to the drawings,,1 indicates a base plateadapted to be fastened ,by screws or other suitable means to the upper face of the top rail of the lower sash of a window, said plate having thereon upstanding earsor lugs 2, in which is slidably mounted a locking bolt consistin of a shank 3, and a hand-piece 4, secure together by pins or rivets, the inner end of the shank 3 being provided with an singularly-disposed T-shaped head 6. For the purpose of normally retraeting the bolt, the latter is provided with a helical, spring 5. operating-between the inner lug or ear 2. and the flanged end of the hand-piece 4.
Mounted on the stile of the upper window sash is a generally flat sheet metal plate T secured to the sash by screws or other appropriate fastening means, and provided throughout its length with a series of spaced horizontal slots 8 of sutlicient size to permit passage of the T-head (3 of the boltmember.
when the latter is turned into horizontal position, but preventing the withdrawal of said head 6 when the same is turned to vertical relation, as indicated in Fig. 2-.
In order to prevent the bolt being accidentally turned, when the same is in locking engagement with the keeper plate 7, the
latter is provided adjacent the edges of the slots 8 with recesses 9. preferably formed by bending or crimping the metal of the plate, as more particularly illustrated in Fig. l.
- In applying the lock to secure the window in open or closed position, the bolt'is turned so that the T-head 6 is horizontal and lies opposite one of the slots 8 in the plate 7.. The bolt is then forced inward against the tension of spring 5, until the T-head 6 passes through the registering slot 8, after which the bolt is given a quarter turn and released. This causes the T-head (5 to drop into the recesses 9 on each horizontal edge of the slot 8, thereby locking the upper and lower sash rigidly together, the spring 5 serving to retract the bolt and hold the same in positive engagement'with therecesses in plate 7.
Obviously, when the sashes are to be locked in closed position, the bolt will be engaged with the lowermost slot in plate T and when either of the sash is to be locked in partially open position. the bolt will be engaged with an appropriate. slot 8 to e'li'ect the desired purpose.
lVhat I claim is:--
A sash lock-comprising a sliding T-headed bolt' adapted to be secured to the top rail of the lower sash, and a flat sheet metal plate adapted to be secured to the stile of the upper sash and provided with a slot to receive the head-of the bolt, said plate having a locking depression for said head at its rear face formed by a bend or crimp in the metal adjacent the slot. and aspring acting on said bolt to retract the same and hold said head firmly seated in said depression.
In testimony whereof I affix my signature.
