PROVIDIUNAL SPECIFICATION.
Improvements in the Construction of Sash Fasteners.
I, WILLIAM LLEWELLYN of Cardiff Barracks, Cardiff, Engineer, in charge of
pumping engine, do hereby declare the nature of this invention to be as
follows.
This invention relates to improvements in connection with sash fasteners, and
has for its object to provide an arrangement which will lock the sashes securely
together.
In carrying out my invention according to one arrangement I propose to screw
en the meeting rail of the lower sash a case of U shape in cross section, beneath
which is placed a holder formed in two parts. The lower part fits on top of the
meeting rail and can be slidden into place. It is provided with a semicircular
groove or channel, and the upper piece is adapted to fit on top of this so as to
complete the cylinder. The cylinder is provided with an internal collar at each
end to form a stop. Within this cylinder is placed a pin or spindle having a
collar which prevents it coming out of place, this spindle being fitted in the
parts before they are placed together. Around the spindle a spring is placed
which withdraws it when released and the end is screw threaded. On the other
meeting rail a socket is screwed having a tapped hole which is adapted to receive
the screwed end of the pin.
To secure the sashes together the pin is pushed forward against the spring
and is turned round being engaged in the socket until the sashes are drawn
together and secured. The spring ensures the window. being drawn securely
together so as to prevent rattling. The spindle is provided with a finger piece
or handle by which it can be turned.
According to a modified arrangement the meeting rail is formed with a hole
which is adapted to receive a cylinder. This cylinder is formed in two halves
which are slidden separately into place, the screwed pin being placed between them.
In the other meeting rail a socket is fitted to receive the end of the screwed
pin, and the socket and each half of the cylinder are provided with flanges or
lugs by which they are screwed in place.

in and by the following statement.
This invention relates to improvements in connection with sash fasteners, and
has for its object to provide an arrangement which will lock the sashes securely
together.
In carrying out my invention according to one arrangement I propose to screw
on the meeting rail of the lower sash a case of U shape in cross section beneath
which is placed a holder. This lower part fits on top of the meeting
rail, and is provided with a semicircular groove or channel, so that when the
two parts are fitted together a cylinder is formed. The cylinder is provided
with an internal collar at each end to form a step. Within this cylinder is
placed a pin or spindle having a collar which prevents it coming out of place,
this spindle being fitted in the parts before they are placed together. Around
the spindle a spring is placed which withdraws it when released. The end is
screw threaded and on the other meeting rail a socket is screwed having a tapped
hole which is adapted to receive the screwed end of the pin.
To secure the sashes together the pin is pushed forward against the spring
and is turned round being engaged in the socket until the sashes are drawn
together and secured. The spring ensures the windows being drawn securely
together so as to prevent rattling. The spindle is provided with a finger piece
or handle by which it can be turned.
According to a modified arrangement the meeting rail is formed with a hole
which is adapted to receive a cylinder. This cylinder is formed in two halves
which are slidden into place the screwed pin being placed between them.
In the other meeting rail a socket is fitted to receive the end of the screwed
pin, and the socket and each half of the cylinder are provided with flanges or
lugs by which they are screwed in place. I prefer to make the end of the pin
square, and to employ a key to screw and unscrew it so that it cannot be opened
by a person except with a suitable key. The arrangement is otherwise similar
to that already described.
In order that the invention may be more clearly understood, reference is had
to the accompanying sheet of drawings in which Fig 1 is a section of my im-
proved window fastener according to one arrangement, Fig 2 is a section at right
angles, Figs 3 and 4 are sections of a slightly modified arrangement, and Fig 5
shows a key to be employed in connection with the fastener.
As shown in Figs 1 and 2 on the meeting rail A of the upper sash a plate B
is screwed carrying the screwed socket b. On the meeting rail A belonging to
the lower sash another plate C is screwed somewhat similar to the first, but
of U shape in cross section. Within the recess of this case a holder D is placed
provided with the small flanges d one at each side taking into grooves in the
lower part of the U shaped plate or case. As shown the upper part of the case
is of semicircular form and the lower part or holder is provided with a semi-
circular groove so that when the two parts are fitted together a cylinder is formed.
The holder is provided with the internal collars done at each end, one half of
each collar being formed on the cover portion of the cylinder and the other on
the lower part or bed. E is the spindle employed to lock the fastener, this spindle
being screwthreaded and is adapted to enter the screwed socket b, and the spindle
is placed in the cylinder formed by the two parts. C and D). The spindle is
placed in the cylinder before the latter is conpleted, being laid in the groove
of the part C. The top or cover D is then put over and the complete holder can
then be fixed to the sash.
The spindle E is provided with the collar e¹ which extends between the two
internal collars and d¹. These collars form stops preventing the spindle being
withdrawn. The spring e² is also provided placed around the spindle and bearing
against one of the collars at one end and against the collar el at the other.
This spring causes the spindle to be withdrawn when it is released from the
socket d, keeping the spindle clear of the opposite sash rail when the fastener is

page_text: not locked. The spindle is also provided with the finger piece e³ by which it can
be operated. To lock the fasteners the spindle is pressed forward against the
force of the spring, and is engaged in the socket. It is then turned until properly
screwed in.
The pins
taking into small holes in the part C serve to hold the latter in
place within the case.
Referring to Figs 3, 4, and 5 the meeting rails A and A¹ are formed with holes
and into the hole of the meeting rail A the socket B is placed being screwed to
the rail by means of lugs. Within the holes of the other meeting rail, the
cylinder D is placed formed in two main parts, each of semicircular shape so
that when brought together a complete cylinder is formed. This cylinder is
similar to the holder described with reference to the previous arrangement, but
is fixed direct to the meeting rail by means of lugs and screws. This cylinder is
also provided with the collars d', and the spindle E is placed within the cylinder
and secured in the manner already described. The spindle in this case may be
provided with the squared end e, which is placed within the cylinder and to lock
and unlock the fastener the key F is employed. provided with a square socket to
fit the end of the spindle.
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
claim is.-
(1) In an improved sash fastener, the combination with a screwed socket on one
meeting rail, and a holder on the second meeting rail formed in two parts united
together to form a cylinder, a screwed spindle fitted in the said cylinder and
means for retaining it in position and for operating it, the spindle screwing into
the socket substantially as described and for the purposes specified.
(2) In an improved sash fastener, the combination with a screwed socket on
one meeting rail, a holder on the second meeting rail formed in two parts united
together to make a cylinder, and two collars in the said cylinder, of a spindle
screwed at one end adapted to enter the socket, a collar on the spindle and a
spring around the same withdrawing it when released, substantially as described
and for the purposes specified.
(3) In an improved sash fastener, the combination with a screwed socket fixed
on one meeting rail of a case or recessed plate fixed on the other meeting rail, a
holder fitted within the said case having a semicircular groove forming with the
top of the case a cylinder, and two collars within the said cylinder, of a screwed
spindle placed in the holder, a collar on the said spindle keeping it in place, and
a spring around the same, substantially as described and shown in Figs 1 and 2
of the drawings, and for the purposes specified.
(4) In an improved sash fastener, the combination with a screwed socket fixed
in a recess in one meeting rail, a cylinder formed in two sections fitted in a
corresponding recess or hole in the other meeting rail, and two collars within the
said cylinder, of a spindle placed within the cylinder, a collar on the said spindle,
a spring around the same causing it to be withdrawn when released, and a square
