8 Claims. (Cl. 70-90)
This invention relates generally to locking devices, and
is especially concerned with a device for locking or secur
ing relatively slidable panels or frames, such as the sashes
of a double-hung window, or the like.
It is one object of the present invention to provide a
securing device of the type described which is relatively
simple and inexpensive to manufacture and install, highly
effective and entirely reliable throughout a long useful
fastener 24, and a lower wall 25 extending inwardly from
the lower end of the outer wall 23. A pair of walls 26
extend generally vertically in parallel spaced, facing rela
tion upward from respective sides of the bottom wall 25
and along the outer wall 23. The housing leg 19‘ opens
inwardly, having no inner wall, for purposes appearing
presently.
The generally horizontal housing leg 29 includes a gen
erally horizontal bottom wall 35} extending outward from
the upper end of outer wall 23 along the upper surface 22
of sash 16 and terminates proximate to sash 15. An
outer wall 31 upstands from the outer end of bottom wall

of the mounting plate 39 with a circumferential groove or
neck 53 de?ning on the plunger an inwardly facing annu

plunger 52 may be provided with an axial extension or
head 55 projecting inward through and beyond the open
ing 48 of the cover plate 46. A cross pin or stop 56 may
be engaged through the plunger or bolt 52 out-ward of the
mounting plate 39; and a coil compression spring 57 may
be circumposed about the plunger between and in engage

the upper end of latch 70 has moved vertically into the
