PROVISIONAL SPECIFICATION.
Improvements in Fasteners for Sliding Window Sashes and
Shutters.
THOMAS POWDITCH INGE 66 Beckenham Lane Shortlands in the County of
Kent Joiner do hereby declare the nature of this invention to be as follows :-
My invention relates to an improvement on sash fastners adapted for sliding
sashes windows and shutters. The said sash fastner is so constructed, so as to
answer for one or two purpoises viz. :-to fasten sashes when they are closed, or to
fasten rashes when they are partly open for ventilation, the sash fastner can be
adjusted so as to prevent any person or persons from opning either sash so as to
effect an entrance from the outer side of sash. The said sash fastner consists of,
cast, wrought irou, or metal. A socket about one inch and a half to three inches
long and about one quarter of an inch to five eights of an inch in diameter with two
or four flanges otherwise plates fixed to the socket for the convenience of fixing the
sash fastner to the meeting rail of bottom sash.
A spindle is placed in the socket so as to move backwards or forwards or to
revolve round, on the end of spindle there will be a metal or china knob for the
convenience of regulating the sash fastner. To keep the spindle in the socket it is
necessary to bore a round, square, or oblong hole, through and through the socket,
also a slotted round, or square hole, longways through and through spindle it is not
necessary to bore the said boles exactly through and through the centre of the said
socket and spindle. At one end of the slotted hole of the spindle it is necessary to
continue the slot either to the right or left angular position, so that when, a pin,
plate, or rivet is fixed in the said hole of the socket the said, pin, plate, or rivet
will project in to the slot of the spindle so as soon as the spindle is pushed to the
end of the slot it can be turned either to the right or left hand so as to lock the
said sash fastner.
On the top sash stile there will be a plate fixed from five eights of an inch to
three quarters of an inch wide and three sixteenth's of an inch, to one quarter of an
inch thick and from five to eight inches long. The said plate will have four or
eight holes bored through and through, so that the spindle will pass in to the said
holes in the plate so as to secure the top and bottom sashes. On the said plate
there will be two or four holes bored through and through for the convenience of
fixing the said plate to the stile of upper sash.

Improvements in Fasteners for Sliding Window Sashes and
Shutters.
I, THOMAS PQWDITCH INGE, of 66 Beckenham Lane, Shortlands, in the
County of Kent, England, Joiner, 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 :—
My invention relates to the fastening of window sashes and shutters which slide
vertically in a frame, and my object is, to fasten the sashs in either a closed
position, or when partly opened for the purposes of ventilation, at the same time,
Poire 811

page_text: prevent any person from opening either sash wider, in order to effect an entrance
into the building from the outside.
But in order that my invention may be better understood I will now refer to the
accompanying sheet of drawings which are to be taken as part of this Specification
and read therewith.
Figure 1, is a perspective view of the fastener in position, connecting the upper
and lower sashes,
Figure 2, illustrates a full sized sash fastener,
Figure 3, is the plate with which the fastener engages, whilst
Figures 4 and 5 shew the arrangement for locking the fastener when the sashes
are attached, and
Figure 6, shews an alternative locking arrangement.
Similar letters of reference indicate similar or corresponding parts where they
occur in the several views.
Now my invention consists, in forming a metallic casing or socket (A) of a
suitable length, to correspond with the width of the lower meeting bar, upon which
it is to be secured by means of screws, which are inserted in holes (B) formed in the
four lugs similar to (C) and (C) projected from the base of said socket (A).
A spindle or bolt (D) is inserted in the socket (A), upon one end of which is the
knob (E) to facilitate the insertion and also withdrawal of said bolt, both into, and
from, either of the holes or perforations (F) made in the plate (G) which is secured
to one style of the upper sash. Said holes or perforations (F) are made slightly
larger than the diameter of the spindle or bolt (D), to allow for play, and may
consist of any suitable number, and arranged at a convenient distance apart from
each other, so that the sashes may be fastened in a position corresponding with
either of the holes.
The movement of the spindle or bolt (D) is regulated, by means of a small pin or
stud (H) projected from the interior of the socket (A) to engage with the recessed
portion (I) formed in said bolt, and when the end of the bolt protrudes to its
furtherest extent, (as is the case when both sashes are attached by the fastener,) the
bolt may be retained in position by giving it a partial revolution, causing said pin
or stud (H) to enter the groove (J) and thus the bolt will be prevented from moving
either backwards or forwards.
This form of locking arrangement may be varied in several ways and still retain
the principle of my invention, for instance, as shewn in Figure 6, I make a plain
slot (K) through the bolt to engage a pin secured diametrically across the socket,
at one end of the slot is formed another slot (L) at an angle so that by giving
the bolt a slight turn, the pin enters this angular slot and retains the bolt in
`position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
Firstly. A sash fastener, consisting of the combination and arrangement of the
socket (A) bolt or spindle (D) and plate (G) substantially as and for the purposes
herein described and as illustrated in my drawings.
Secondly. In sash fasteners, the combination and arrangement with the
socket (A) and bolt or spindle (D), of the recess (1), pin or stud (H) and
groove (J) substantially as and for the purposes herein described and as illustrated
in my drawings.
Dated this 21st day of August 1894.
