Description
UNITED STATES PATENTA OFFICEc ROBERTVLEE, OF CINCINNATI, OIIIO.
IMPRovED sASH-FASTENlNG.
Specification `forming part of Letters Patent No. 47,962, dated May 30, 1865.
i window. I
O is a plate secured by wood-screws to thel top of the rail A, and vhaving a stud-pin, D, which occupies a slot, E, in a latch, F, which is held backward against the stud pin by 'means of a spring, G, and follower H.` The latch `F has also a lip, I, which, in the act of locking, engages over a catch, J, whose plate L is screwedfast to the rail B, and whose talon K co-operates with the spring G to retain the latch F in the locked condition. The latch F is released by first pushing it longi-n tudinally forward until its lip I is clear of the talon K, and then swinging it back against the stop M. This fastening is also free from liability to have its screws drawn out bythe sudden or violent lifting of the lower sash, the
stress being direct upon the screws instead of operating with a purchase or leverage, as in thecommon form. Y
It will be perceived that this fastening cannot, like the common form, be opened from without by means of a knife or like instrunient passed upward between the two meetingrails, because the insertion of such an instrument must act to spread the sashes away from each other, and to cause the latch F and catch J to more rmly interlock; The effect of the Afastening is also obviously to press the two meeting-rails firmly together, so as to make a tight joint and to'prevent rattling.
I claim herein as new and of my invention- The arrangement of spring-latch F and catch J with their described or equivalent accessories, the whole being combined'and operating to form a secure sash-lock, substantially as set forth.
In testimony of which invention I hereunto set my hand.
ROBERT LEE.
