Improvements in Screw Fasteners for Doors and Windows.
JOHN BUCKLEY PODMORE, Vicar of Cowfold, The Vicarage, Cowfold, Sussex,
I, the said John Buckley Podmore, do hereby declare the nature of this inven-
tion to be as follows:-
The above may be made in cast iron or in other metal & is the strongest of
sash fasteners, applied to a door it keeps out the draught & is a great security
against burglars.
The stay which clips the fastener is of solid iron 3/8" & " in its narrowest
part, it stands 1" above sash & is " deep, this casting is fixed on the back
sash flush with the front of it. The bolt or fastener carrying the working screw
turns upon a strong pivot fixed in the back sash, the friction of which holds the
fastener in position when turned back to the window & in this position the
fastener is held parallel to the window by its contact with the base of the
above mentioned stay & it is fixed in a line with it, thus dispensing with the
usual spring in sash fasteners. A countersink plate is fixed on front sash under
large screw the turning of which makes it run down countersink & draw the two
sashes together & also forces back sash upwards to frame of window which
prevents rattling.
I. Screw fasteners generally work horizontally or are fixed at an angle, with
a view to drawing sashes together.
This screw fastener works perpendicularly and after drawing the sashes
together by the aid of a countersink plate or front sash, it lifts up the back
sash to the frame of the window, thus shutting out top draught, & preventing
window from rattling.
II. Sash cords are liable to stretch & the back sash to go down, which prevents
the free working of ordinary sash fasteners, this fastener is elevated in such
manner as to pass over the front sash, & it works equally well on on bad fitting
as on perfect windows.
III. The greatest improvement in this screw fastener is in its strength & sim-
plicity of construction, in this respect it has surpassing advantages, dispensing
with the requirement of a spring, by reason of the friction of its base on the
sash, & of a lighter and more expensive metal.. It can therefore be made at
half the cost & with five times the strength of an ordinary fastener.
FOR DOORS.
This screw fastener does not require the countersink plate, it is fixed with
long wrought iron screws. It is much stronger than ordinary door bolts, & by
forcing the door to its frame it resists the insertion of the burglars forcing tools
& excludes the draught of badly fitting doors.

JOHN BUCKLEY PODMORE, B.A., Vicar of St. Peters, Cowfold, The Vicarage,
Cowfold, Sussex, 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:―

The stay which clips the bolt or fastener is of solid iron & is in the shape of
the letter Z (zed) A Fig. 2 the top limb of the letter or stay being " from
left to right" thick & % across the top of it, & the bottom limb " from
right to left, the neck of the stay is also " thick. The stay stands upon a
plate thick 1%" x 1" on surface, which is part of the same casting. The
space between the top limb plate or base in which the fastener rests when
pulled round is ". In the base or plate of the above stay two holes are cast
or drilled, one on the right hand & one on the left B B Fig. 1 through those
two holes strong screws pass & fix it to the back sash & flush with the front
of it, a third hole is drilled in the back of the base or plate & tapped C Fig. 1
which carries the screw or pivot, upon which the bolt or fastener turns. The
pivot is so fixed that the bolt or fastener when pulled round will fit the space
for receiving it.
#
The bolt or fastener stands 5/8" high it is 3/8 wide & 1" in length to front of
sash D Fig. 2 beyond this it extends " & is 3/8" square reaching over the
front sash.
A strong thumb screw E Fig. 2 works at the end of the bolt or fastener and
will pass over the front sash even though it be "above the back sash.
The back of the bolt or fastener has a small projection F Fig. 1 which when
turned round comes in contact with the neck of the stay G Fig. 1 which holds
it parallel with the window, this together with the weight of the bolt and friction
on plate dispenses with the necessity of a spring.
Under the large screw a countersink plate H Fig. 1 is fixed, the turning of
the screw forces the end of it down the countersink, draws the sashes together
and lifts the back sash fixing it to the top frame of window.
For doors this screw fastener does not require the countersink plate, it is
fixed with strong wrought iron screws, it is much stronger than an ordinary
door bolt, & by forcing the door to its frame it resists the insertion of the burglars
forcing tools & excludes the draughts of badly fitting doors.
Having now particularly described the nature of my said invention & in
what manner the same is to be performed I declare that what I claim is:―
I. A screw fastener which works perpendicularly & after drawing the sashes
together by the aid of a countersink plate on front sash, lifts up the back sash
to the frame of the window thus shutting out top draughts & preventing rattling
of windows or sashes.
II. I claim an improved screw fastener that will work equally well on bádly
fitting windows as on perfect ones.
III. I claim a screw fastener of great strength, that requires no spring, &
can be made in iron or brass.
