This Victorian window latch was patented on April 3,1877, according to the back stamp. It is quite uncommon. This is the only one we have. Even though it was manufactured during the Victorian era, it is void of any pattern or design. The latch works by an unseen spring. When the knob is pushed, the spring releases allowing the round head of the latch to swing open. The arm of the latch slips into the channel of the keeper when in locked position.
The latch’s mounting plate measures 2 3/8 inches long and 1 1/4 inches wide. The keeper’s base is 2 1/2 inches by 7/8 inch. The hole centers on both pieces is 1 7/8 inches.
This latch is a heavy, solid cast-iron piece. Screws will be included.
