page_text: We JOHN WALKER and HENRY BAXTER WORSEY both of No. 14 Edmund Street
Birmingham in the County of Warwick Hardware Factors and Manufacturers do
hereby declare the nature of this Invention to be as follows:-
Our invention consists of the construction and combination herein after described
of the parts of sash casement and door fasteners.
We will describe our invention as applied to a sash fastener.
We make the jointed arm carried by the meeting rail of the top sash in two
parts each part having a different function from the other. The lower part of the
compound arm has a cylindrical head or end which works in a cylindrical case
carried by the fixing plate of this part of the fastener the said lower part having
motion through about a quadrant. We will call the lower part of the compound
arm the jointed part At the outer end of the said jointed part of the arm is
a fork projecting below the lower face of the jointed part and the upper face of
the said jointed part carries a loop. Upon the upper face of the jointed part of
the compound arm a sliding part hereinafter called the spring bolt works a coiled
spring around the inner end of the bolt pressing the said bolt inwards or towards
the top sash. The outer end of the sliding bolt passes through the loop of the
jointed part and has a turned up finger plate by which the outward sliding motion
is given to the spring bolt and the compound arm turned on its joint. On the
underside of the outer end of the spring bolt is a projecting catch which works
between the branches of the projecting fork on the underside of the jointed part of
the arm.
The inner end of the sliding bolt is made into a locking pin and in the
cylindrical case in which the joint of the arm works is a hole or opening of a size
suitable for the locking pin on the spring bolt to engage with. When the
compound arm has been moved into its fastening position that is made to cross
at right angles the meeting rails of the two sashes the locking pin is brought
opposite the hole in the case into which hole the said pin snaps and thereby locks
the spring bolt in its fastening position. A stud on the inner end of the spring
bolt works in a guide slot in the circular head or end of the jointed part of
the arm.
In place of the ordinary quadrant fixed on the meeting rail of the bottom sash
for the jointed arm on the meeting rail of the top sash to engage under we use on
the said bottom sash a plate having its outer edge curved and slightly excentric to

page_text: the motion of the jointed arm. With this curved edge the projecting fork of the
jointed arm engages for drawing the two sashes together. At the middle of the
said curved excentric edge of the fixed plate on the lower sash is a recess or slot
in which the catch on the spring sliding bolt engages.
When the two sashes are unfastened the compound jointed arm is situated
parallel to the top sash and the spring of the spring bolt is in a state of tension.
In order to fasten the sashes the jointed arm is made to cross the two sashes. As
the arm is turned on its joint the projecting fork works against the curved
excentric edge of the fixed plate on the bottom sash and the two sashes are forcibly
drawn together. As soon as the arm has crossed the two sashes at right angles
the catch of the spring sliding bolt is brought opposite the notch or recess in the
said fixed plate and the locking pin at the opposite end of the sliding bolt is
brought opposite the hole in the case. The sliding bolt being now at liberty to
move its catch snaps into the notch or recess in the fixed plate and thereby fastens
the two sashes together and the locking pin at the same time snaps into the hole
in the case and locks the sliding bolt in its fastening position.

To unfasten the sashes the sliding bolt is pulled outwards so as to withdraw its
locking pin from the hole in the case and its catch from the notch in the fixed
plate when the jointed arm may be turned on its joint and the sashes unfastened.
We construct and combine the parts of casement and door fasteners substantially
in the manner herein before described with respect to a sash fastener.

page_text: We JOHN WALKER and HENRY BAXTER WORSEY both of No. 14 Edmund Street,
Birmingham in the County of Warwick Hardware Factors and Manufacturers, do
hereby declare the nature of our Invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:
Our invention consists of the construction and combination hereinafter described
of the parts of sash, casement and door fasteners.
We will describe our invention as applied to a sash fastener.
We make the jointed arm carried by the meeting rail of the top sash in two
parts, each part having a different function from the other. The lower part of the
compound arm has a cylindrical head or end which works in a cylindrical case.
carried by the fixing plate of this part of the fastener, the said lower part having
motion through about a quadrant. We will call the lower part of the compound
arm the jointed part. At the outer end of the said jointed part of the arm is.
a fork projecting below the lower face of the jointed part and the upper face of
the said jointed part carries a loop. Upon the upper face of the jointed part of
the compound arm, a sliding part herein after called the spring bolt works, a coiled,
spring around the inner end of the bolt pressing the said bolt inwards or towards
the top sash. The outer end of the sliding, bolt passes through the loop of the
jointed part and has a turned up finger plate by which the outward sliding motion
is given to the spring bolt and the compound arm turned on its joint. On the
underside of the outer end of the spring bolt is a projecting catch which works
between the branches of the projecting fork on the underside of the jointed part of
The inner end of the sliding bolt is made into a locking pin and in the
cylindrical case in which the joint of the arm works is a hole or opening of a size,
suitable for the locking pin on the spring bolt to engage with. When the
compound arm has been moved into its fastening position, that is, made to cross,at,
right angles the meeting rails of the two sashes the locking pin is brought opposite
the hole in the case, into which hole the said pin snaps and thereby locks the
spring bolt in its fastening position.
the arm.
In place of the ordinary quadrant fixed on the meeting rail of the bottom sash
for the jointed arm on the meeting rail of the top sash to engage under, we use on.
the said bottom sash a plate having its outer edge curved and slightly excentric to
the motion of the jointed arm. With this curved edge the projecting fork of the
jointed arm engages for drawing the two sashes together. At the middle of the
said curved excentric edge of the fixed plate on the lower sash is a recess or notch
in which the catch on the spring sliding bolt engages.
Figure 1 of the accompanying Drawing represents in side elevation; Figure 2 in'
plan and Figure 3 in longitudinal section, a sash fastener constructed according to
our invention, the parts being in their fastened positions; Figure 4 represents in

plan partly in horizontal section the said fastener with its compound arm moved
through a quadrant for unfastening the sashes; Figure 5 represents the fastener
in end elevation with and without the top or sliding bolt and Figure 6 represents
a side elevation of the under or jointed part of the compound arm of the fastener
separately.
The same letters of reference indicate the same parts in the several Figures of
the drawing; a, b are the two meeting rails of the sashes That part of the
fastener fixed to the meeting rail a of the top sash consists principally of the
compound jointed arm c, d and the cylindrical case e the two parts c, d of the
compound arm having different functions as hereinafter pointed out. The inner
end of the lower part d of the compound arm carries a cylindrical head d' which
works in the cylindrical case e about one half of which case is cut away at e³ (see
Figure 4) to permit of the motion of the said arm through a quadrant. On the
outer end of the lower or jointed part d is a fork d³ which projects below the
lower face of the said part d and in the upper part of the said fork is a loop d'
(see Figure 5). Upon the upper face of the jointed part d of the compound arm,
a sliding part or spring bolt c works, a coiled spring faround the inner end c³ of
the bolt c pressing the said bolt inwards or towards the top sash a. The outer
end of the bolt o passes through the loop d' in the fork d³ of the jointed part d
and has a turned up finger plate by which the outward sliding motion is given
to the said bolt c and the compound arm c, d turned upon its joint, that is, the
circular head d' is made to turn through a quadrant in the fixed case e. The outer
end of the spring bolt c has also a projecting catch which works between the
branches of the projecting fork ds of the jointed part d (see Figure 5). The
extreme end c³ of the sliding bolt c acts as a locking pin a hole g in the fixed
case e being made for the said end of the bolt to snap into when the bolt is in its
faening position as best seen in Figure 3. On the meeting rail b is a fixed
plate h the outer edge of which is curved and slightly excentric to the motion of
the jointed arm c, d. With this curved and excentric edge of the plate h the
projecting fork d³ of the lower part d of the compound arm engages for drawing
the two sashes a, b together. At the middle of the curved excentric edge of the
fixed plate h is a recess or notch i (see Figure 4) in which the catch c of the
spring sliding bolt c engages when the compound arm has been brought into its
fastening position, that is, made to cross at right angles the meeting rails a, b of
the sashes as represented in Figure 3. When the two sashes a, b are unfastened,
the compound jointed arm c, d is situated parallel to the top sash a and the spring f
of the spring bolt c is in a state of tension as represented in Figure 4. In order to
fasten the sashes, the jointed arm c, d is made to cross the two sashes by grasping
the handle end and turning the said arm through a quadrant. As the arm c,
is turned upon its joint the projecting fork d³ works against the curved excentric
edge of the fixed plate h on the bottom sash b and the two sashes a, b are forcibly
drawn together. As soon as the compound arm c, d has crossed the two sashes at
right angles, the catch c' of the spring sliding bolt c is brought opposite the notch
or recess in the said fixed plate hand the locking pin c at the opposite end of
the sliding bolt, o is brought opposite the hole g in the fixed case 6.
The sliding
bolt being now at liberty to move its catch c* snaps into the notch or recess i in
the fixed plate h and thereby fastens the two sashes together and the locking
pin cat the same time snaps into the hole g in the case e and locks the sliding
bolt c in its fastening position as represented in Figures 1. 2 and 3.
()
To unfasten the sashes the sliding bolt c is pulled outwards by its thumb plate
or handle c³ so as to withdraw its locking pin c³ from the hole g in the case e and
its catch c from the notch i in the fixed plate h when the compound jointed
arm c, d may be turned on its joint and the sashes unfastened as represented in
Figure 4. We construct and combine the parts of casement and door fasteners
substantially in the manner herein before described and represented with respect
to a sash fastener,
