COMPLETE SPECIFICATION.
Improvements in Sash Fasteners.
I, ARTHUR ILLIDGE, of the firm of S. Illidge and Son, of Alexandra Foundry,
Wolverhampton in the County of Stafford, Brassfounders and Lock Manufacturers
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 :-
This invention refers to improvements in or relating to what is known as
Faulkner's sash fastener, whereby the manufacture is greatly facilitated with
consequent reduction in cost.
In Faulkner's sash fastener, a short arm of an L-shape or T-shape in cross-
section is pivoted to the mounting to which the fastener arm (or arm which engages.
when fastened, with a mounting on the inner sash) is pivoted. Vertical teeth are
formed on the pivoted end of each arm and the teeth of one arm are geared with
those of the other, the arms being placed in such position in relation to one another
that when the fastener arm is back or unfastened, the short arm lies back also, but
in the opposite direction. As the fastener arm is moved forwards across the top
of the inner sash the short arm also moves automatically therewith forwards across
the slit or parting between the. meeting rails. When the fastener arm has been
drawn forwards some distance a spring, which has been compressed by the move-
ment of the inner end of the arm, rebounds and forces the two arms together so
that they both stand forwards square across the slit or parting between the rails;
and when the arms are in such position the vertical member of the L-section, or
the head of the T-section, of the short arm is against the side of the fastener arm,
and the horizontal member (that is the lower member of the L or the stalk of
the T) passes underneath the fastener arm, or into a rebate or recess formed
therein, and thus the fastener arm is prevented from being unfastened by a knife or
other instrument inserted between the meeting rails. The formation, however, of
the teeth on the inner ends or eyes of the arms is an expensive operation, even when
the parts are made, as usual, of brass; and the expense would be much greater if the
short arm were made of wrought iron or steel, which substances are better adapted
for the purpose on account of their greater toughness and of their capability of
being hardened and of resisting in a hardened state any attempt to saw through
them.
Now, according to this invention, the teeth are dispensed with altogether, and in
lieu thereof the arms are connected together by means of a link or pair of links,
or are geared together or engaged with one another by means of a pin or stud
carried by one of the arms (preferably the fastener arm) which engages with a
slot formed in the other arm, whereby, in either case, both arms move together in
the manner required. As, by 'this invention, the teeth are dispensed with, the
short arm may be readily stamped in iron or steel, and requires little or no fitting
beyond forming the hole for the pin on which it turns, and the hole for the pivot.
of the link or links, or the slot, as the case may be. The inner end of the fastener
arin is also prepared much more readily than when teeth have to be formed thereon
as in Faulkner's sash fastener.
Convenient means of carrying out this invention practically are illustrated by
the drawings herewith, of which
Figure is a plan of a sash fastener having the tivo arms linked together by a
single link. The top plate of the mounting which carries the arms is supposed to
be cut away, and the mounting usually fixed on the inner sash is oniitted as it is of

page_text: the usual construction. The arms are shewn in their backward or unfastened
position.
Figure 2 is a corresponding view to Figure 1, but shews the arms in their forward
or fastened position.
Figure 3 is a front elevation with the arms in the position shewn by Figure 1.
Figure 4 is a view, taken as a section on line of Figure 2.
Figure 5 illustrates a modification in which the arms are connected by a pair of
links, and is a view corresponding to Figure 3 but shews, for convenience of
illustration, only so much as is necessary to distinguish this modification from the
other.
Figures 6, 7 and 8 are views corresponding, respectively, to Figures 1, 2 and 3,
but illustrate a modification of the invention in which a stud carried by the fastener
arm engages with a slot formed in the short arm.
Referring first to the modification illustrated by Figures 1 to 4 inclusive, A is
the mounting of the usual character within which the fastener arm B and short
arm C are pivoted by means of pins D and E, respectively. The fastener arm B
is formed with a portion a which operates in combination with a fixed spring 6 in
the usual manner, and for such purpose may be provided with a friction roller cor
not as desired. The inner end d of the fastener arm is connected with the short
arm by means of a link e which may be pivoted to the fastener arm and short
arm, respectively, by portions el at the ends of the link turned down at right
angles to the main length thereof and entering within holes in the fastener arin
and short arm, as shewn, or by means of separate pins passing through holes in
the ends of the link and into the holes in the arms. The pivot centres of the
link are in such position, in relation to the pivot pins D and E on which the
arms turn, as shewn, that as the fastener arm is moved forwards into the position
shewn by Figure 2 the short arm is pulled by the link into the position shewn
also by such view, and, so that the reverse movement, of the fastener arm will
cause the link to push the short arm back again into the unfastened position
shewn by Figure 1. The short arm is formed with a vertical part which, when
the arms are in the position shewn by Figure 2, comes against the side of the
fastener arm, and with a horizontal or Hat party which, when the arms are in such
position, comes under the fastener arm, as seen more clearly in Figure 4.
part g may, however, be formed to enter a rebate in the lower edge of the fastener
arin, or may project from about the middle of the part and enter a recess formed
in the fastener arm. It is preferred, however, that it shall pass right across the
underside of the fastener arm, as shewn.
The
In Figure 5 the fastener arm B is connected with the short arm C by means of
a pair of links hh, and pins ii (shewn by broken lines only). These pins are
quite plain, that is to say, without heads or other provision for retaining them in
place endways, as they are kept in place by the top and bottom plates of the
mounting A.
A further modification consists in an arrangement of jawed ends of the fastener
arm and short arm, respectively, and a central link having its ends pivoted within
the jaws, which will be readily understood without need for illustration.
Referring now to the modification illustrated by Figures 6, 7 and 8, the inner
end of the fastener arm B carries a pin or stud! (shewn in Figures 6 and 7 by
broken lines only) which engages with a slot m in the short arm C, the pin or stud
and slot being in such position, as shewn, in relation to the pins D and E on which
the arms turn, that as the fastener arm is moved forwards into the position shewn
by Figure 7 the pin thereof, operating within the slot m, moves the short arm
also into the position shewn by Figure 7, and as the fastener arm is moved back
again into the position shewn by Figure 6 the pin moves the short arm back
again into its position shewn in such figure.
In describing the modifications shewn, respectively, by Figure 5 and Figures 6, 7
and 8, I have described only the features which distinguish these modifications from

page_text: that shewn by Figures 1 to 4 inclusive, the other features being in substance
common to all the modifications.
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
::
1. The fastener arm and short arm, of a sash fastener of the character above
defined and referred to as "Faulkner's sash fastener, connected together by means
of a link or links, or geared together by means of a pin and slot, (in lieu of teeth
formed on their inner ends with the teeth of one gearing with the teeth of the
other) substantially as described.
2. The several modifications of a sash fastener of the character above defined
and referred to as "Faulkner's" sash fastener, having the fastener arm and short
arm connected or engaged with one another, substantially in the manner described
with reference to the drawings herewith.
