PROVISIONAL SPECIFICATION.
Improvements in Sash or Window Fasteners.
I, ENOCH EVANS, of Bentley Lodge, Bentley Lane, Walsall, in the County of
Stafford, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to sash or window fasteners and consists of a two-part.
fastener attached respectively to the meeting rails of the window sashes, and has for
one of its objects, a simple and efficient fastener, and for another object, a safety
apparatus for preventing a window being lowered beyond a given distance when the
same is opened for ventilation.
One part of the fastener consists of an attachment plate with a turning down front.
edge and an overhanging rib or feather at the top of the said front edge and mounted.
upon the middle of the said plate is a swivelling screw box wherethrough the left-hand
screwed middle of a stem having a turn at its outer end and a stud or button at its
inner end, passes and works.,
By rotating the stem from left to right the head is made to retire or be pulled
inwards, and on rotating the same from right to left the said head is propelled
outwards.

The other part of the fastener consists of a gapped or bayonet-slotted upright
bracket, with an attachment foot plate at its lower end. The slot or gap is closed
at its top end and has an open side gate or lead at its bottom, whilst the front face
of the bracket is toothed or serrated, between the cross channels of which, the fillet.
or feather on the front of the attachment plate of the other part of the fastener
comes and engages.
'
The head or button of the first named part is engaged with the slot or gap of
the other part and the parts are then drawn together by the rotation of the stem.
OPERATION.
Assuming that the meeting rails of a window have been brought together and
require to be fastened, and assuming the stem to be lying in the same general
direction as the sash bar, swing the stem upon its pivot to a right angle, when that
part of the same immediately behind the stem or button passes through the side gate.
into the gap. Then rotate the stem, which is repelled and the sashes are drawn
together and the feather or rib on the one part is drawn tightly into one of the
hollows in the toothed face of the gapped plate when the fastener becomes locked
with the windows closed.
To leck the window in a slightly open position, say to the extent of two or three
inches for the purposes of ventilation, first loosen the fastening by propelling the
screwed stem and then slide the top sash down to a distance equal to or within the
extent of the slot. Then repel the stem, when the sashes become again locked in any
position within the range of the slot or gap.
To release the sashes, propel the stem and bring the sash bars level with one
another and then swing the said stem round upon its pivot so as to bring its head or
disc button over the bar of the one sash and clear from the other sash and the gapped
plate carried by it when the window can be fully opened.

page_text: By my invention windows can be safely fastened in slightly open positions for
the purposes of ventilating at night or other times during hot weather.

ԱՅՆԵՂԵՆ,
I. ENOCH EVANS of Bentley Lodge, Bentley Lane, Walsall, in the County of
Stafford, Manufacturer, do hereby declare the nature of this invention and in what
manner the same is to be perforined, to be particularly described and ascertained in
and 'by the following statement :-
This invention relates to sash or window fasteners, and consists of a two-part
fastener attached respectively to the meeting rails of the window sashes; and has for
one of its objects, a simple and efficient fastener, for another object the fixing of a.
window in either a limited open position for ventilation or in a closed position.
One part of the fastener consists of an attachment plate with a turned-down front
edge and a long tooth or teeth, or an overhanging rib or feather at the top of the
said front edge, and mounted upon the middle of the said plate is a swivelling. screw
box wherethrough the left-hand (preferably) screwed middle of a stem having a turn
at its outer end and a stud or button at its inner end, passes and works.
By rotating the stem from left to right the head is made to retire or be pulled
inwards, and on rotating the same from right to left the said head is propelled
outwards.
The other part of the fastener consists of a gapped or bayonet-slotted upright
bracket, with an attachment foot plate at its lower end. The slot or gap is closed at
its top end and has an open side gate or lead at its bottom, whilst the front face of
the bracket is toothed or serrated, between the cross channels of which, the fillet,
tooth or feather on the front of the attachment plate of the other part of the fastener
comes and engages.
The head or button of the first named part is engaged with the slot or gap of the
other part and the parts are then drawn together by the rotation of the stem.
Figure 1 of the accompanying drawings represents a perspective view of my
improved sash fastener applied to the meeting rails of the sash and showing the
window fastener in a partly opened position.
Figure 2 represents an elevation of the gapped upright bracket forming one
part of the attachment, showing the stem of the other part lying within the gap
thereof.
Figure 3 represents a topside plan of the fastener, with the gapped 'bracket in
section upon the dotted line Figure 2, and the head and stem of the other part
swivelled round clear of the said bracket, in which position it is placed when the
window is to be opened for a considerable distance or to its fullest extent.
Figure 4 is a topside plan showing the two parts of the attachment fastened
together.
Figure 5 is a transverse vertical section upon the dotted lines 2, Figure 4 and
Figure 6 is an elevation of the stem-carrying part of the fastener, showing the
long tooth on the front edge of the same for engaging with the teeth or serrations
on the presented surface of the gapped bracket.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.

page_text: A is the fastener, consisting of two parts a and b, the former comprising the
attachment plate a', with turned down front edge a³, and long tooth or overhanging
rib a3 and carrying the screw box a', swivelly mounted thereon, and wherethrough
the screwed middle part c', of the advancing and retiring stem c, having a head or
button at one end and the turn-piece c³, at the other end, passes, whilst the
attachment bracket b', of the other part b, carries the upright bracket b', which is.
bayonet-slotted at 3, with a gate or opening, sleading into the bottom part of the
same. are the teeth or serrations on the front face of the bracket, where with the.
tooth or rib a, of the other part engages when the rails of the sash are drawn
together as hereinafter described.
OPERATION.
Assuming that the meeting rails of a window have been brought together and!
require to be fastened and assuming the stem to be lying in the same general
direction as the sash bar, swing the stem upon its pivot to a right angle, when that
part of the same immediately behind the head, stem or button passes through the
side gate into the gap of the bracket. Then rotate the stem, which is repelled and
the sashes are drawn together and the long tooth, feather or rib on the one part is
drawn tightly into one of the hollows in the toothed face of the gapped plate of the
other part, when the fastener becomes locked with the windows closed.
To lo k the window in a slightly open position, say to the extent of two or three.
inches for the purposes of ventilation, first loosen the fastening by propelling the head
of the screwed stem out of contact with the gapped bracket and then slide the top.
sash down to a distance equal to or within the extent of the slot. Then repel the
stem, when the sashes become again locked in any position within the range of the.
slot or gap..
To release the sashes, propel the stem and bring the sash bars level with one.
another and then swing the said stem round upon its pivot and out of the gate of its
slot, so as to bring its head or disc button over the bar of the one sash and clear-
from the other sash and the gapped plate carried by it when the window can be fully
opened.
Instead of a long tooth or rib of the one part engaging between teeth or notches on
the opposed face of the other part, I may employ the equivalent in the form of a.
stud or studs adapted to engage in one or other of a series of holes or sinkings in the
opposed face of the upright bracket and instead of employing a long toothed bearer
I may employ a plain upright bearing and the head end of the stem of the turn may
carry a loose and tooth-faced bear block spring and swivelling upon its end and
adapted to engage with like teeth or serrations on the back of the gapped upright
bracket.
By my invention windows can be safely fastened in slightly open positions for the
purposes of ventilating at night or other times during hot weather.
Having now particularly described and ascertained the nature of my said inven-..
tion, and in what manner the same is to be performed, 1 declare that what
I claim is
First. A two-part window fastener, with the one part consisting essentially of a
gapped or slotted bracket, having teeth, serrations or the like, with which a tooth or
teeth or equivalent of the other part engages for locking the one sash to the other,.
in either a closed or partly opened position, after the said sashes have been drawn
together by the operation of a closing device such as a screw turn or equivalent.
Secondly. A two-part window fastening, one part consisting of a gapped or slotted
upright bracket having transverse teeth or serrations upon its face, with which a tooth
or rib on the other part engages after the sashes have been drawn together by the
head of a swivelly-mounted screw pin coming behind the first-named bracket and_
drawn up by rotation, substantially as described and set forth.

page_text: Thirdly. The general construction, arrangement and combination of the parts of
sash fasteners, substantially as and for the purpose described and set forth.
