COMPLETE SPECIFICATION.
Improved Fastener for Window Sashes, Casements, Doors and
the like.
ALFRED BARTER 22 Newcomen.Terrace Coatham Redcar Yorkshire Mechanical
Engineer 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:-
A permanently fixed appliance for fastening or securing window sashes, case-
ments, door and the like.
My invention consists of a bracket with a sliding adjustable link attached to
it, which bracket is fixed on the inner or lower sash also a hook fixed on the
outer or upper sash for afore mentioned link to pass over. The link having a set
screw cam or the like attached to one end of it, by which means it adjusted or
tightened up.
The above mentioned bracket may have pegs or projections on it, for the link
to slide between, the said pegs or projections being so arranged so as to allow
the link to cant to any required angle.
Or the link may have slots or grooves in it so allowing it to slide on pegs or
projections on the afore mentioned bracket.
The bracket carrying sliding link which is fixed on the lower or inner sash
may be made higher than the hook fixed on the upper or outer sash, so that
when the link is in position it stands at an angle, by this means when the link
is tightened up, it lifts one sash up, and forces the other down and at the same
time araws the meeting rails of the sashes together.
The details and mode of construction may be varied without departing from
the principle of action.
Figs. 1, 3, 4 and 5 are side elevations of different modifications of fastener.
In each modification the set screw is marked A, the link B, the bracket carrying
link D, and the hook E.
Fig. 1. Is a side elevation of one modification with fastener fixed on meeting
rails of window sash showing the link B passed over the hook E and adjusted
or tightened up by means of the set screw A, by unscrewing the set screw A the
link B is disengaged from hook E and then slides between the pins or projec-
tions and g to position B' as shewn by dotted outline of link.
Fig. 2. Is a plan of Fig. 1 showing the top pins or projections
side of the bracket D.
on each
Fig. 3. Is another modification, the link B having slots or grooves K in it,
one on each side, so allowing it to slide on the pins or projections g on the
bracket-I).
Fig. . In this modification the link B slides in grooves in the ends of the
cylindrical block H, the cylindrical block H being free in the bracket 1 to
make a rotary movement thus allowing the link B to cant to any required angle.
The bracket D having a piece cut away on the upperside to allow the set
screw A to screw down on the cylindrical block H.
Fig. 5. Is a side elevation of a modification shewing the link B used horizon-

page_text: tally the inside of hook E being formed at an angle so that the tightening
up of the link B by the means of set screw A has a tendency to lift the hook-E.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
First. The several modifications and arrangements of fastener for window
sashes, casements, doors and the like, substantially as hereinbefore described and
illustrated by drawings.
Secondly. The use of a sliding or loose adjustable link for fastening window
sashes, casements, doors and the like.
