IMPROVE- MENTS IN QUADRANTS FOR OPENING, SHUTTING, AND FASTENING WINDOWS
Year: 1873

page_text: LETTERS PATENT to John Edward Beanland, Builder's Manager, of
Bradford, in the County of York, for the Invention of "IMPROVE-
MENTS IN QUADRANTS FOR OPENING, SHUTTING, AND FASTENING WINDOWS, AND
ealed the 27th February 1874, and dated the 1st December 1873.
PROVISIONAL SPECIFICATION left by the said John Edward Beanland
at the Office of the Commissioners of Patents, with his Petition, on
the 1st December 1873.
I, JOHN EDWARD BEANLAND, Builder's Manager, of Bradford, in the
County of York, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN QUADRANTS FOR Opening, ShuttING, AND FASTENING WINDOWS,
AND IN THE APPARATUS EMPLOYED THEREIN," to be as follows, that is to
say :-
My Invention relates to the employment of a quadrant working on a
stud or pin which is moved in or out of gear by means of a moveable
lifting lever or arm worked by a rod or rope.

page_text: To carry out my Invention I employ a bracket fixed to the window
frame in which is fitted a quadrant working on a stud or pin; this
quadrant can be fixed on the side, top, or bottom of the window; catches
are formed in the quadrant enabling the window to be opened and fixed
in any position, and at the extreme end of the quadrant is fitted a stop
which can be easily removed when the window is required to be lowered
to release the window from the quadrant. On the window is fixed a
guide in which the quadrant works; the bottom part of this guide acts
as a stop for the catches formed in the quadrant; on the guide is fitted
a lifting lever so constructed that the lifting part releases the quadrant
from the stop of the guide when pulled by means of a rod placed in an
arm formed on the lifting lever, or by a rope fastened to the arm passing
over friction pullies. The lifting part of this lifting lever can be made
with a flat surface or with a friction roller, acting not only as a lifting
lever to release the quadrant, but also as a slide.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Edward Beanland in the Great Seal Patent
Office on the 1st June 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
EDWARD BEANLAND, Builder's Manager, of Bradford, in the County of
York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the First day of December, in the year of
our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Edward Beanland, Her
special licence that I, the said John Edward Beanland, my executors,
administrators, and assigns, or such others as I, the said John Edward
Beanland, 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 QUADRANTS FOR OPENING, SHUTTING AND FASTENING WINDOWS,
AND IN THE APPARATUS EMPLOYED THEREIN," upon the condition (amongst

page_text: Figure 4 represents a side view of a quadrant for opening and shutting
windows by means of a rod or by a rope. Figure 5, front view; and
Figure 6, plan of the same.
Figure 7 represents a side view of a quadrant fitted to the side of a
window frame worked by a rope; Figure 8, front view of the same.
Figure 9 represents a lifting lever fitted to windows hung on pivots.
Similar letters of reference are used in all the Figures to represent
similar parts.
A, window frame; B, window; C, bracket fixed to the window frame
A, in which is fitted a quadrant D working on a stud or pin E; on the
quadrant D are formed notches or catches F. to allow of the opening and
fixing of the window in different positions; on the extreme end of the
quadrant D is fitted a stop G which can be easily removed when the
window is required to be released from the quadrant by removing the
pin H. On the window is fixed a bracket I, the top part forming a
guide J in which the quadrant D works; the bottom part of the guide J
acts as a stop for the notches or catches F formed on the quadrant D;
on the bracket I is fitted a lifting lever K having a lifting piece L
formed thereon to release the quadrant D from the stop on the bottom
part of the guide J, shewn in dotted lines; the lifting part K is actuated
by the lever M when pulled by a hook fixed on a rod, the lever Ķ is
secured to the bracket I by the stud or pin N.
In Figures 4, 5, and 6, the bracket I fitted to the window is shown
made with a guide J in which the quadrant D works; this guide J is
made with sides forming an opening O to receive the friction pulley P,
over which a rope Q passes; on the bracket is formed a boss R having
an opening through which is fastened the end of the rope Q; the
bracket C fixed to the window frame is made with a recess to receive the
friction pulley P¹, the rope Q being fixed to the boss R is passed over
the friction pulley P¹, then over the friction pulley P, and by pulling
the rope Q the window can be opened or shut. The lever K is formed
at one end with lugs to receive a friction roller S to lift the quadrant D
from the notches or catches F, as shewn in dotted lines; this friction
roller S acts as a lifting lever and as a slide for the quadrant D. On the
other end of the lever K is fitted a ring T, through which is passed the
hook of the rod for opening and shutting the window; when the rope Q
is used the lever K is not required.

page_text: The quadrant in Figures 7 and 8 is fitted to the side of the framework
of the window, and is worked by a rope only; the bracket C is also
made to receive a friction pulley P³, over which passes the rope Q. On
the guide J formed on the bracket I through which passes the quadrant D
is formed a lug U through which is passed the rope Q, passing from
thence over the friction pulley P¹, and to the bottom part V of the
lever K; by pulling the rope Q it will lift up the lifting piece L of the
lever K, releasing the square notches or catches F of the quadrant D,
thus allowing the opening, shutting, and fastening of the window.
Figure 9 represents a different form of lifting lever fitted to windows
hung on pivots; K, lifting lever fitted to the bracket I and fixed by
means of the pin N. L, lifting part of the lever acting on the
quadrant D; M, opening through which is passed the hook of the rod or
a ring of a cord.
Having thus described my improvements, and the best means I am
acquainted with for carrying the same into effect, I would have it under-
stood that I do not confine myself to the precise details shewn and
described, as the same may be varied without departing from the peculiar
character of the Invention, but what I claim is, the improved quadrant
operating in the manner and by means of the lifting apparatus, sub-
stantially as and for the purposes herein-before described and represented
in the accompanying Drawing.
In witness whereof, I, the said John Edward Beanland, have hereto
set my hand and seal, this Thirtieth day of May, in the year
of our Lord One thousand eight hundred and seventy-four.
