Office of the Commissioners of Patents, with his Petition, on the 2nd
September 1867.
HENRY VALLANCE, of Farnham Royal, in the County of Bucks, Gentle-
man; do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN FASTENINGS SUITABLE FOR CASEMENT WINDOWS," to be as follows:-
This Invention has for its object improvements in fastenings suitable for
casement windows. With a latch fastening such as has heretofore been
employed and which is carried by an arm or cross bar forming part of the
casement window frame. I. combine a rod which passes down by the side
of the easement frame, and then is bent at right angles so as to pass a
distance along the bottom of the frame; this bar rises and
latch it is confined to the casement frame by suitable guides.

spring presses the bar downwards, and causes a locking pin at its end to bear
upon a quadrant. leaded or otherwise fixed into the window cill. The quadrant
has holes in it at short distances apart into which the locking pin can drop, and
so the casement when open can be secured in any desired position; by raising
the latch the locking pin is drawn out of the hole in the quadrant, and the
casement may then be closed and fastened by the latch, or shifted to another
position. In place of applying the spring to the horizontal portion of the
descending bar it may be applied directly to the latch, or springs may be
applied in both positions.
The arrangement may be modified by making the bar in two parts, the one,
the upright part, descending from the latch, the other, the horizontal limb,
which is then connected with the casement frame by a stud or pin, on which
it is able to turn. The locking pin and quadrant may be arranged at the top
of the casement, but less conveniently.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Vallance in the Great Seal Patent Office on the
29th February 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
VALLANCE, of Farnham Royal, in the County of Bucks, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of September, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself. Her heirs and successors, give and grant unto me, the
said Henry Vallance, Her special licence that I, the said Henry Vallance, my
executors, administrators, and assigns, or such others as I, the said Henry
Vallance, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN FASTENINGS
SUITABLE FOR CASEMENT WINDOWS," upon the condition (amongst others) that
I, the said Henry Vallance, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and in

page_text: what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Vallance, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in fastenings suitable for
casement windows. With a latch fastening such as has heretofore been
employed, and which is carried by an arm or cross bar forming part of the
casement window frame, I combine a rod which passes down by the side of
the casement frame, and then is bent at right angles so as to pass a distance
along the bottom of the frame. This bar rises and falls with the latch, but is
confined to the casement frame by suitable guides. The horizontal limb of
the bar is acted upon by a spring, which may be fixed to the casement frame;
this spring presses the bar downwards and causes a locking pin at its end
to bear upon a quadrant leaded or otherwise fixed into the window sill. The
quadrant has holes in it at short distances apart into which the locking pin
can drop, and so the casements when open can be secured in any desired posi-
tion; by raising the latch the locking pin is drawn out of the hole in the
quadrant, and the casement may then be closed and fastened by the latch or
shifted to another position. In place of applying the spring to the horizontal
portion of the descending bar it may be applied directly to the latch, or
springs may be applied in both positions.
The arrangement may be modified by making the bar in two parts, the one,
the upright part, descending from the latch, the other, the horizontal limb,
which is then connected with the casement frame by a stud or pin, on which
it is able to turn. The locking pin and quadrant may be arranged at the top
of the casement, but less conveniently.
And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawings hereunto
annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front view, and Figure 2 a plan in section of a casement
window having a fastening constructed according to my Invention; Figure 3
is a front view of a portion of the same, shewn about the full size; Figure 4
is a vertical section; and Figure 5 a horizontal section.
aa, is a rectangular iron frame set into masonry, brickwork, or wood-

page_text: work b, as the case may be; c is the casement frame hinged to it; on one side
it has a bar e passing across it, on which the latch is mounted; d is the glass
secured in the frame c by means of metal rails fixed to the frame c around
the edges of the glass by tap screws, or the glass may be secured in other con-
venient ways; e is the latch plate, it is attached to the cross bar e by the
screws e, e', one of which also serves as the pivot for the latch /; g is a strap
fixed at each end into the latch plate and confining the latch to it; h is a
spring fixed at one end to the latch plate, and at the other pressing on the top
of the latch, or the spring may be otherwise applied, as already stated; i is a
projection from-the frame a, a notch in the latch catches upon it; k is a rod
jointed to the end of the latch in such manner as to be retained and moved
up and down by it; this rod descends from the end of the latch along in front
of the frame e to the bottom angle thereof (as it stands when the latch is
down), and then it follows along the bottom of the frame c to the point k',
where it terminates in a pin or bolt; is a slotted hole in the rod k, through
which a pin with a head upon it is screwed into the frame c; it serves to
guide and retain the rod / as it rises and falls; I is a lug fixed to the frame c
at the end of the bar, also to retain and guide it; m is a quadrant with
holes formed in it at intervals, as it is shewn in the Drawing; it is fixed by
screws to the frame a, or it may be leaded into or otherwise secured to the
masonry, brickwork, or woodwork; is a handle, it is firmly attached to the
latch plate e, but in such manner that it can turn freely; it has upon it the two
arms e, e, and on these the latch rests. When the handle n is turned partly
round, the casement being closed, one or other of the arms e lifts the latch so
as to free it from the projection i, and at the same time the latch raises the
rod, and the pin or bolt at ' is withdrawn from the innermost hole in the
quadrant m. into which when the window is closed and fastened it penetrates;
the casement may now be more or less opened, and so secured by allowing the
pin or bolt at to enter another of the holes m¹. In some cases the frame c
is made in wood in place of in metal.
Figure 6 is a front view of such a casement, and Figure 7 is a plan in section
of the same. The outer metal frame a is also dispensed with, b, b, being of wood
and having the frame e hinged to it direct. The cross bar e' in this arrange-
ment is in metal and is independent of the glass. As before mentioned the
quadrant may be placed at the top of the casement frame, but less
conveniently.
The details of the arrangement may be varied; but what I claim is the
combining with the latch fastening of a casement window a rod passing along
the frame to a pin or bolt locking with a quadrant in such manner that the

page_text: movement of the latch handle is communicated to the said locking pin or bolt,
as above described.
In witness whereof, 1, the said Henry Vallance, have hereunto set my
hand and seal, this Twentieth day of February, in the year of our
Lord One thousand eight hundred and sixty-eight.
H. VALLANCE. (L.S.)
