A SAFETY VENTILATING SASHFASTENING
Year: 1884

page_text: I ARTHUR FREDRICK GARROOD, Baker, of Rutland Road South Hackney, in
the County of Middlesex, do hereby declare the nature of my Invention for
A SAFETY VENTILATING SASHFASTENING to be as follows:-
The invention is designed to allow of a space (say half an inch) being left
between the upper and lower sash frames of an ordinary window for the purpose
of Ventilation, and by a modification of the ordinary Sashfastener to effectually
secure the same from being opened from the outside by a knife or instrument. It
can also be used on a nonventilating sash and will then prevent the fastening from
being opened in the before mentioned manner.
An ordinary sashfastening is made in two pieces. viz. the catch and the arm, each
mounted on a plate which is screwed to the sash. In this invention the catch is
not altered but the plate under the arm is extended forward so as to cover the
space between the sashes, the arm being also lengthened as may be necessary, this
extension plate is to be hinged to the arm plate. Above this lower extension plate
is an upper horizontal plate supported at one end by an upright stay connecting it
with the extension plate so that the arm works between these two extended plates.
At the other end of the enclosure thus formed there is a hanging plate, hinged from
the end of the upper extension plate, & projecting therefrom a pin or stud rosting
on the moveable arm in such manner that the said arm is guarded from attack from
the side or beneath The effect of this pin is to keep the hinged hanging plate
from being lifted up, unless the arm is first moved, and the arm can only be thrust
back by pushing the knob at the end thereof, whereupon the said arm lifts the
hanging plate & coming in contact with a vertical pin or stay throws back the
entire enclosure which is placed on the extension plate.
It is a special feature of this invention that the entire arrangement is moved to
and fro by a single action. viz: the movement of the arm of the fastener in the
ordinary way. The movement of the arm throws back instantly and automatically
the entire arrangement, and in the same way when the arm is drawn forward the
entire mechanism comes forward with it, and the sash is immediately secured.
Dated this 14th day of March 1884.

page_text: I, ARTHUR FREDERICK GARROOD of Rutland Road, South Hackney in the
County of Middlesex, Baker; do hereby declare the nature of my invention for
A SAFETY VENTILATING SASHFASTENER and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention is designed to allow of a space, say of half an inch, being left
between the upper and lower sash frames of an ordinary window for the purpose
of Ventilation, and by a modification of the ordinary Sashfastener to effectually
secure the Sash from any attempt to open it from the outside by a knife or by an
instrument with a loop thrust up between the sashes and allowed to drop over and
drag the end of the arm or latch of the fastener. It is also applicable as a safety
or secure fastener where ventilation is not needed.
An ordinary Sashfastener is made in two pieces, viz: the catch and the armor
latch, each mounted on a plate which is screwed to the sash. In this invention the
catch is not altered but the arm is lengthened, and is made by preference of Steel
or hardened metal, and the plate under the arm has a hinged plate attached to its
front edge hereinafter referred to as the extension plate. This extension plate is
continued upwards, perpendicularly at one end and brought over so as to form three
sides of a rectangular enclosure, inside which the arm works. At the unattached
end of the upper horizontal plate is a hanging plate hinged thereto, and projecting
from this hanging plate is a pin or stud resting on the arm in such manner, that
the said arm is fully protected from any attack coming either from above; the side,
or beneath. The offect of this pin is to keep the hinged hanging plate from being
lifted up unless the arm is first moved, and the said arm can be thrust back only
by pressure applied to the knob thereof, in the front of the fastener. When this is
done the arm lifts the hanging plate and coming into contact with a vertical pin or
stay, throws back the entire enclosure which is placed on the extension plate.
It is an important feature of this invention that the entire arrangement is
moved to and fro by one simple motion, viz: the pushing of the arm of the
fastener in the ordinary way. Pressure applied to the arm throws back instantly
and automatically the series of plates forming the box or enclosure around the arm,
and in the same way when the arm is drawn forward, the entire mechanism comes
forward with it and the Sash is immediately secured.
In the accompanying drawings Fig. 1 represents an elevation of my improved
Bash fastener in the closed position as fixed on the centre bars of an ordinary sash.
Fig. 2 is an elevation in the open position Fig. 3 is a plan closed, and Fig. 4 is
a plan open. Fig. 5 is a view in perspective taken from the right side.
A. represents the Catch, B the arm or latch. CC are plates fixed to the Sash.
D is the Extension plate. E is the upper horizontal plate. G is the hanging plate.
H. the pin or arm I the knob at end of latch.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I would remark
in conclusion that I do not confine myself to the exact shape & construction of the
parts heroin described, as the invention is susceptible of considerable modification
to suit different sashes & casements without affecting the principle involved, but
I declare that what I claim is :-
I. The construction of a Sash fastener of the ordinary latch & catch type
opening or closing in the usual way by a single movement, viz: the lateral
pressure of the thumb & finger, substantially in the manner and for the purpose
described,

page_text: II. The construction of a Sash fastener which admits of ventilation when
fastened, by the admission of fresh air between the adjacent bars of two ordinary
Sashes, substantially as and for the purpose described.
III. The general construction as herein described of a moveable cap or enclosure.
whereby the arm or latch of the fastener is enclosed and protected and which
secures the effect before stated and is applicable to purposes of ventilation when
required substantially in the manner hereinbefore described.
