Year: 1879

page_text: LETTERS PATENT to William Richard Barter, of the City of Manchester, in the
County of Lancaster, Engineer, for the Invention of "IMPROVEMENTS IN
WINDOW OR SASH FASTENERS."
Sealed the 18th November 1879, and dated the 27th May 1879.
PROVISIONAL SPECIFICATION left by the said William Richard Barter at
the Office of the Commissioners of Patents on the 27th May 1879.
WILLIAM RICHARD BARTER, of the City of Manchester, in the County of Lan-
caster, Engineer. "IMPROVEMENTS IN WINDOW OR SASH FASTENERS."
The object of my improved fastener is not only to draw the two bars of the sashes
firmly and securely together, but at the same time to force one sash up and the
other down, so that they will be thus firmly held at the top and bottom as well as
where they join together, and will thus prevent the noise and rattle of the sashes
by vibration or the action of the wind; the object of my Invention is also to arrange
the fastener so that it may be locked if desired, or so that it cannot be fastened or
unfastened except by the proper key or handle.
My Invention consists of a hook, bracket, or stand secured by screws to the lower
cross bar of the upper sash, and also of another bracket secured to the upper cross
bar of the lower sash, the two brackets being opposite each other.
In the two up-
right arms of the bracket on the lower sash there are bearings which carry the
trunnions on a part resembling a cannon in shape, in the bore of which bearings for
a screw spindle are formed, which screws into a part with a loop at its out end,
which looped part can slide freely in the enlarged bore of the part resembling a
cannon, and this looped part has a projection from it that slides in a longitudinal
slot in the cannon part, which thus prevents the loop part from rotating with the
screw.
The window is secured by depressing the loop part over the hook bracket and
then turning the screw, which pulls diagonally so as to bring the two sashes close
together, and at the same time force one sash up and the other down.
The handle of the screw is either made permanently attached or so as to be
detached and fit as a socketted key into the bore and on to the end of the screw,
which is left within the bore, so that it can only be turned by its proper key.

page_text: The hook on the upper sash is or may be made double according to my Inven-
tion, one hook some distance above the other, so that when required the two sashes,
may be secured together when opened a few inches so as to prevent a further
opening of them.
Instead of a hook on the upper sash there may be a loop and a hook in place of
the loop; in fact the details and mode of construction may be varied without
departing from the principle of action.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Richard Barter in the Great Seal Patent Office on the 22nd
November 1879.
WILLIAM RICHARD BARTER, of the City of Manchester, in the County of Lan-
caster, Engineer. "IMPROVEMENTS IN WINDOW OR SASH FASTENERS."
The object of my improved fastener is not only to draw the two bars of the sashes
firmly and securely together, but at the same time to force one sash up and the
other down, and also one sash to one side and the other to the other side, so that
they will be thus firmly held at the top and bottom and sideways as well as where
they join together, and, will thus prevent the noise and rattle of the sashes by
vibration or the action of the wind; the object of my Invention is also to arrange
the fastener so that it may be locked if desired, or so that it cannot be fastened or
unfastened except by the proper key or handle.
My Invention consists of several modifications, one modification being a hook,
bracket, or stand secured by screws to the lower cross bar of the upper sash, and also
by another bracket secured to the upper cross bar of the lower sash, the two brackets
being arranged opposite each other.
In the two upright arms of the bracket on the lower sash bar there are bearings
which carry the trunnions on a part resembling a cannon in shape, in the bore of
which bearings for a screw spindle are formed, which screws into a part with a loop
at its outer end, which looped part can slide freely in the enlarged bore of the part
resembling a cannon, and this looped part has a projection from it that slides in a
longitudinal slot in the cannon part, which thus prevents the loop part from rotating
with the screw.
The window is secured by depressing the loop part over the hook bracket and
then turning the screw, which pulls diagonally so as to bring the two sashes close
together, and at the same time forces one sash up and the other down.
The handle of the screw is either made permanently attached or so as to be
detached and fit as a socketed key into the bore and on to the end of the screw,
which is left within the bore, so that it can only be turned by its proper key.
The hook on the upper sash is or may be made double according to my Inven-
tion, one hook some distance above the other, so that when required the two sashes
.may be secured together when opened a few inches so as to prevent a further
opening of them.

page_text: Instead of a hook on the upper sash there may be a loop and a hook in place of
the loop; in fact the details and mode of construction may be varied without
departing from the principle of action.
Fig. 1 is a side elevation, and Fig. 2 a plan of one modification and arrangement.
Fig. 3 a side elevation, and Fig. 4 a plan of another modification and arrangement,
with the key for turning the screw shown detached by Fig. 5.
Fig. 6 is a side sectional elevation, and Fig. 7 a plan of another modification and
arrangement.
Fig. 8 is a side elevation, and Fig. 9 a front elevation of another modification.
Figs. 10 and 11, and Figs. 12 and 13 are respectively side and front elevations of
other modifications of my Invention.
In each modification the lower bar of the upper sash is represented or marked a,
and the upper bar of the lower sash as represented or marked b.
The hook or part attached by screws or otherwise to the upper sash a is marked
al, and the bracket or stand secured by screws or otherwise to the lower sash b is
marked bl.
The modifications shown by Figs. 1 and 2 and Figs. 3, 4, and 5 are the same,
except that the modification represented by Figs. 3, 4, and 5 has a key x to turn the
screw, and the parts are arranged diagonally in plan.
The
In Figs. 1 and 2 and in Figs. 3 and 4 the bracket b' has bearings for the
trunnions c¹ of the cannon part c, which has bearings for a screw c² (see Fig. 3) that
screws through a loop part c³ that can slide in the bore of the cannon part c.
loop part has a projection ct that slides in a slot in the cannon part c to prevent
the part c³ from turning round.
The loop part c³ passes over the hook a¹, and then the screw c³ is rotated, in the
modification illustrated by Figs. 1 and 2, by the fixed handle c5, and in the modifi-
cation illustrated by Figs. 3, 4, and 5 by the box key x, which fits the square on the
end of the screw c².
In the modification represented by Figs. 1 and 2 the two sash bars a and b are
drawn together, and one is forced up and the other down. In the modification shown
by Figs. 3 and 4 the apparatus is arranged diagonally as shown in Fig. 4, and
besides producing the result above described the sashes are drawn sideways, one
sash one way, the other sash the other way, to take away entirely the play of the
sashes by binding them against each other and against the top, bottom, and sides of
the window frame.
In Fig. 3 the hook a¹ is shown double, so that the loop 3 may be passed under
the upper hook, and then the upright part a* being hinged at a² the upper hook can
be drawn by the screw against the end of the cannon part c so as to lock it secure,
and thus leave the window partly open, but so as to prevent it from being further
opened or unfastened.
In the modification shown by Figs. 6 and 7 the bracket b' carries the bearing of
the screw, which screws through a part having trunnions upon it, which can slide
to and fro on slots in the bracket.
The trunnions have a loop e jointed upon them, which can be looped over the
hook a', so that by turning the screw c² by the head c³ the two sashes are drawn
together.
In the modification shown by Figs. S and 9 the bracket b' carries the bearing of
a screw c², which can oscillate in the are of a link e jointed to the bracket b' and
to a trunnion part c³ on the screw, which trunnion part has a loop c also jointed to
it, which can pass under the hook al, as shown. By turning the screw cone way
the action is to pull upwards and sideways in the arc of the link c.
In the modification shown by Figs. 10 and 11 the bracket b' has a loop c³ attached
to it, which has a bearing for the end of the screw c² to rotate in, and this screw
screws through a loop c³ that passes over the hook a¹ when the sashes are to be
secured by turning the screw c² by means of the arins c*.
In the modification shown by Figs. 12 and 13 the bracket b¹ carries the bearings

for a worm or screw c², the thread of which works in teeth in a wheel c³, also
having its bearings in the bracket b¹.
To the part a¹ a loop a³ is jointed, which can be turned so as to come into the
space between the teeth of the wheel c, so that by turning the screw c² the sashes
are drawn together. The loop a³ near the joint is weighted, or a spring is made to
act to keep it in a vertical position when released from the teeth of the wheel.
The loop 3 may be jointed to the wheel c³, and arranged to loop upon a hook,
same as the loop ce upon the hook a', Fig. S.
I arrange all or any of the above described modifications of my Invention when
required in a diagonal position, as shown in Fig. 4, so as to pull the sashes
sideways.
I have now particularly described the nature of my said Invention and the
manner of carrying the same into effect, and claim as my Invention,―
Firstly. The combination and arrangement of sash fasteners so that the sashes
will not only be drawn together but will be forced up and down simultaneously, or
both drawn together and forced up and down and sideways simultaneously, sub-
stantially as hereinbefore described, and illustrated by the Drawings.
Secondly. The combination and arrangement of the several modifications of sash
fasteners, substantially as hereinbefore described, and illustrated by the Drawings.
In witness whereof, I, the said William Richard Barter, have hereunto set
my hand and scal, this Twenty first day of November, in the year of our
Lord One thousand eight hundred and seventy nine.
