PROVISIONAL SPECIFICATION.
Improvements in Self-acting Sash Fasteners Combined with
Sash Lifts.
I JAMES COLLINS of 26 Cumberland Street Birmingham Brassfounder do hereby
declare the nature of this invention to be as follows:-
I screw on the bottom rail of the sash a plate having a projection near its top
edge and I pivot on this projection a rocking piece suitably shaped on the top to
receive the fingers & having its lower part provided with a hook or catch which
engages with a suitable keeper fixed on the fence bead or on the sill of the window
frame.
When it is desired to open the window, the fingers take hold of the upper part
of the rocking piece which then rocks on the pivot & disengages the lower part from
its keeper so leaving the sash free to rise. When the window is being closed the
lower part of the rocking piece comes against the keeper & is slightly moved till
the projections pass when it falls into its normal position by the action of gravity
& fastens the window.

COMPLETE SPECIFICATION.
Improvements in Self-acting Sash Fasteners Combined with
Sash Lifts.
JAMES COLLINS of 26 Cumberland Street, Birmingham' Brassfounder do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
I screw on the bottom rail of the sash, a plate having a projection near its top
edge, and I pivot on this projection a rocking piece suitably shaped on the top to
receive the fingers and having its lower part provided with a hook or catch which
engages with a suitable keeper fixed on the fence bead, or on the sill of the
window frame.
When it is desired to open the window, the fingers take hold of the upper part of
the rocking piece, which then rocks on the pivot and disengages the lower part from
its keeper, so leaving the sash free to rise.
When the window is being closed the lower part of the rocking piece comes
against the keeper and is slightly moved till the projections pass, when it falls into
its normal position by the action of gravity, (or a spring may be used if so desired)
and fastens the window.
Drawing No. 1 shows a window fastened. A is the plate. B the pivot. C the
rocking piece. D the keeper.
Drawing No. 2 shows a window in the act of being opened or closed, and the
rocking piece C disengaged from the keeper D.
Drawing No. 3 shows a modification where a projecting "D" keeper as in No. 1
is objected to, the same letters indicate similar parts.
Drawing No. 4 shows another modification in which the rocking piece slips
over a plate, made in same shape as the fence bead, and has a ring instead of a hook
on the rocking piece, the same letters indicate similar parts.
I do not bind myself to any of the shapes set forth above, as they may be variously
modified to suit special shapes of sashes, or other requirements.
