Improvements in the Catches or Fasteners of Windows, Shutters,
and Doors.
I, HENRY WEATHERILL, of 33, Beech Street, Waterloo Road, Cheetham,
Manchester, in the County of Lancaster, Coach Builder, do hereby declare the
nature of this invention to be as follows:-
I prepare a plate or part or parts to attach to the outer part or half of the
window frame. To such plate or part or parts I rivet or otherwise, suitably
attach a spring lever bar so that the said spring lever bar may turn on the said
plate or part or parts. I prepare another plate or part having a catch made
with or suitably attached to it. Such last named plate or part with catch is
attached to the inside part or half of the window frame and is so. formed and
arranged that it can butt up to or slightly overlap the plate or part fixed on the
first named outer part of the window frame so that when the window is closed
the spring lever bar is drawn across and catches in a notch formed or made in
or on the catch that is made with the part attached to the second named or
inside part of the window frame and thus prevents a knife or other appliance
being inserted between the two parts and forcing the spring lever bar from its
holding position.
My invention will be better understood on reference to the accompanying sheet
of drawings and the following explanations.
A spring lever bar is arranged to spring or snap into a notch 'formed in a
catch so that when fixed in position on windows, shutters and doors it is difficult,
if not impossible, to force the spring lever bar out of its place with a knife or
other instrument when applied from the opposite side to which the fastener is
attached. The spring lever bar may also be used with the catch as a fastener
without the catch having a notch formed in it. One end of the spring lever
bar "A" as shown in Figure 3 will press against the catch the other end will
press against the window sash or door and will check vibration.

such sashes should slide up and down past each other or 'slide past each other
from side to side. A is the spring lever bar. "B" is the catch which has a
notch formed in it to receive the spring lever bar "A" as shown at "C" in

with plate "F," the raised part "G" is to prevent the spring lever bar "A"
being pulled down or otherwise removed by a hook or other instrument and so
pulled or otherwise removed out of the notch. "H" is the knob which must be
pressed down before the spring lever bar "A" will leave notch "C" as shown

Figure shows the spring lever bar "A" of a stronger kind which takes all
its spring from its bed or bearing the coil spring "N." The holes in the spring
lever bar "A" may fit casy on the bolt "0" to let the spring lever bar "A"
play when required or the bolt "0" may fit easy in the plate "E" and the
plate Ebe countersunk for a round sided nut to work in as shown. When
the nut "P" is screwed up the bolt end "O"may be rivetted up to keep nut on.
The plate "E" to form bed or bearing for coil spring "N" will be tapered to
throw up the nob end of spring lever bar A" as much as is necessary to get
the required spring pressure.
The drawings are not to any scale.

Improvements in the Catches or Fasteners of Windows, Shutters,
and Doors.
I, HENRY WEATHERILL, of 33, Beech Street, Waterloo Road, Cheetham,
Manchester, in the County of Lancaster, Coach Builder, 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 prepare a plate or part or parts to attach to the outer part or half of the
window frame. To such plate or part or parts I rivet or otherwise suitably
attach a spring lever bar so that the said spring lever bar may turn on the sai
plate or part or parts. I prepare another plate or part having a catch made
with or suitably attached to it. Such last named plate or part with catch is
attached to the inside part or half of the window frame and is so formed and
arranged that it can butt up to or slightly overlap the plate or part fixed on the
first named outer part of the window frame so that when the window is closed
the spring lever bar is drawn across and catches in a notch formed or made in
or on the catch that is made with the part attached to the second named or
inside part of the window frame and thus prevents a knife or other appliance

holding position.
My invention will be better understood on reference to the sheet of drawings
already lodged with my Provisional Specification and the following explanations.
A spring lever bar is arranged to spring or snap into a notch formed in a
catch so that when fixed in position on windows shutters and doors it is difficult,
if not impossible, to force the spring lever bar out of its place with a knife or
other instrument when applied from the opposite side to which the fastener is
attached. The spring lever bar may also be used with the catch as a fastener
without the catch having a notch formed in it. One end of the spring lever
bar "A" as shown in Figure 3 will press against the catch the other end will
press against the window sash or door and will check vibration or one end of
the spring lever bar may be attached to a frame part or part acting as a frame
part the other end of the spring lever bar being arranged to press against the
window or door or part acting a similar part to a window or door in such case
the catch may or may not be used.

Figure 1 shows the fastener applied to window sashes when it is intended
such sashes should slide up and down past each other or slide past each other
from side to side. "A" is the spring lever bar. "B" is the catch which has a
notch formed in it to receive the spring lever bar "A" as shown at "C" in
Figure 2. D" is a coil spring on which the spring lever bar A" is bedded
and attached to plate "E" by a rivet or bolt" as shown. "F" is a plate to
which the catch "B" is secured or rivetted or catch "B" may be made solid
with plate "F," the raised part "G" is to prevent the spring lever bar
being pulled down or otherwise removed by a hook or other instrument and so
pulled or otherwise removed out of the notch. "H" is the knob which must be
pressed down before the spring lever bar "A" will leave notch "C" as shown
in Figure 2. iii are parts of sash frames.

page_text: 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:-
_
The arrangement of a spring lever bar to be constructed and applied in the
manner and for the purposes. mentioned and substantially-set forth in the fore-
going specification and shown in the drawings already lodged with my Provisional
Specification.
