page_text: LETTERS PATENT to George Edwards, of 147, Brompton Road, South Kensing-
ton, in the County of Middlesex, Architect, for the Invention of "IMPROVED
APPARATUS FOR AND MEANS OF FASTENING, OPENING, AND CLOSING SLIDING
WINDOW SASHES."
Sealed the 27th July 1877, and dated the 12th February 1877.
PROVISIONAL SPECIFICATION left by the said George Edwards at the
Office of the Commissioners of Patents on the 12th February 1877.
GEORGE EDWARDS, of 147, Brompton Road, South Kensington, in the County of
Middlesex, Architect. "IMPROVED APPARATUS FOR AND MEANS OF FASTENING,
OPENING, AND CLOSING SLIDING WINDOW SASHES."
My Invention relates,—
Firstly. To an improvement on the fastening for sashes, &c., for which Letters
Patent were granted to me on the 12th November, 1875, No. 3935.
And, Secondly. To a simple and effective means for raising and lowering sliding
window sashes with cords worked in combination with the said improved fastening.
And, Thirdly. To an improved method for securing or fastening sliding window
sashes by means of cords, by which I can entirely dispense with a spring fastening
fixed to the meeting rails of the sashes.
My improvements, firstly and secondly above referred to, consist of the following
alterations in the fastening for sashes, for which Letters Patent were granted to me
as aforesaid, namely, the substitution for the screw knob or nut of pullies, and also the
use of a cord running over the said pullies for the purpose of pushing back the bolt,
whereby I am enabled to obviate the necessity of reaching up to the fastening to
release or unfasten it, and also to get rid of the knob or nut projecting in front of
the sashes, which sometimes interferes with blinds and shutters.
Another improvement on the said fastening is, that instead of using a screw knob
or nut to tighten and lock the sashes, I do so by means of a lever working on an
nclined plane.

page_text: My improvement, thirdly above referred to, consists of improved means of raising,
lowering, and fastening sliding sashes, and consists of four strong cords, two of which
sash; tho two
are fixed to the top, and two to the bottom of the styles of the upper
lower cords pass over two upright pullies (expressly inade for the purpose) fixed on
each side of the top rail of the lower sash. These cords hang down by the side of
window. At a convenient height from the floor I attach handles, and by means of
this arrangement I am enabled to close both of the sushes, and when closed, I attach
these handles to fastenings or locking plates, fixed at the required level, which
fastenings or locking plates act as sash lifts; by using wire, rope, gut, or other strong
material cord, I am enabled to secure and fasten both sashes in the most effectual
manner.
By use of another locking plate fixed at a different level from those previously
described the window can be opened for ventilation, and at the same time be per-
fectly secure from the outside.
To prevent persons tampering or cutting the cords used for securing the sashes
from the outside, I use a guard attached.to the plate on the upper sash, by which
the cords are fixed.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said George Edwards in the Great Seal Patent Office on the 11th August
1877.
"
GEORGE EDWARDS, of No. 147, Brompton Road, South Kensington, in the County
of Middlesex, Architect. IMPROVED APPARATUS FOR AND MEANS OF FASTENING,
OPENING, AND CLOSING SLIDING WINDOW SASHES."
My Invention relates,―
Firstly. To an improvement on the fastening for sashes, &c., for which Letters
Patent were granted to me on the 12th day of November, 1875, No. 3935.
And, Secondly. To a simple and effective means for raising and lowering sliding
window sashes with cords worked in combination with the said improved fastener.
And, Thirdly. To an improved method for securing or fastening a window by
means of cords, by which I can entirely dispence with a spring fastening fixed to
the meeting rails of the sashes.
My improveinents, firstly and secondly above referred to, consist of the following
alterations in the fastening for sashes for which Letters Patent were granted to ine
on the 12th of November, 1875, namely, substitution for the screw knob or nut
attached to a bolt enclosed with a spiral spring, and working with a horizontal
motion in a case fixed upon the meeting rail of the lower sash, of pullies, and also
the use of a cord running over the said pullies, for the purpose of pushing back or
throwing forward the bolt to unlock the fastening, whereby I am enabled to obviate
the necessity of reaching up to the fastening to release or unfasten it, and also to
get rid of the knob or nut projecting in front of the sashes, which sometimes
interferes with blinds and shutters.
Another improvement on the said fastening is, that instead of using a screw knob
or nut to tighten and lock the sashes, I do so by means of a lever attached to the
bolt of the fastener, working on an inclined plane formed in the case enclosing the
bolt and spiral spring.
My improvement, thirdly above referred to, consists of improved means of raising,
lowering, and fastening sliding sashes, and consists of four strong cords, two of which
are fixed to the top and two to the bottom of the stiles of the upper sash; the two
lower cords pass over two upright pullies (expressly made for the purpose) fixed on
each side of the top rail of the lower sash; these hang down by the side of the
window, and at a convenient height from the floor I attach handles, and by means

page_text: of this arrangement I am enabled to close both of the sashes, and when closed, by
attaching these handles to hooked or other fastenings or locking slates, which may
also act as sash lifts fixed at the required level, I securely fasten the window. By
using copper or iron wire, rope, gut, or other strong material for cord, I am enabled
to secure and fasten both the sashes in the most effectual manner without the aid of
a spring fastener.
By use of another locking plate fixed at a different lovel from the one previously
described, the window can be opened for ventilation, and at the same time be per-
fectly secure from the outside.
To prevent persons from tampering with or cutting the cords used for securing
the sashes from the outside, I use a guard attached to the plates on the upper sash,
by which the cords are fixed.
In order that my Invention may be clearly and fully understood, I annex
Drawings, by the aid of which I will proceed to describe the means adopted for
carrying the same into effect, and for that purpose I shall refer to the several Figures
on the annexed Sheet of Drawings, the same letters indicating corresponding parts
in all the Figures.
Figures 1, 2, and 3 are plan, section, and olevation of my improved fastening,
shewing how the same is made for the purpose of being fixed to the meeting rails in
the centre of a window.
Figures 4, 5, and 6 are plan, section, and elevation of my improved fastening,
showing how the same is made when fixed to the meeting rails at the side of a
window. a, a, is a cord, one end of which is fixed to the top part of the upper sash
of a window, and passes down over the pullies b, b, and finishes with a handle
attached at a convenient height, and which, when pulled, unlocks the fastening and
pulls down the upper sash simultaneously.
Figures 7 and 8 represent side and front views of an improved upright pulley,
having a guard e, which pulley is fixed on each side of the upper rail of the lower
sash of a window; c, c, represent cords, wire, rope, or other material. One end of
each cord is fixed to the stiles of the lower part of the upper sash on each side
thereof by means of the plate d. These cords pass over the upright pullies and have
handles attached at a convenient height, and when either the upper sash is down or
the lower sash is up, or both sashes are open at the same time, by pulling these
handles, one or both sashes may be closed and fastened at pleasure.
In Figures 4, 5, and 6, one of the said improved upright pullies is attached by the
side of my improved fastening.
Figures 9, 10, and 11 are plan, section, and elevation of my improved fastening,
and shew the lever f, as described, working on the inclined plane g.
Figures 12, 13, and 14 represent plan, elevation, and section to a smaller scale
of a window fitted with sliding sashes, double hung in the usual way, shewing my
improved fastening, pullies, and cords affixed thereto, with the fastening in the
centre of the window.
Figures 15 and 16 also represent a window shewing the improved fastening,
pullies and cords affixed thereto at the side thereof.
Having thus described my Invention, and means which I adopt in carrying the
same into effect, what I claim is,-
1st. The improvements on my original fastening for sliding window sashes as
regards the unlocking of the same by means of cords working in combination with
the said fastening by pressing or propelling the bolt in a horizontal direction, both
inwards and outwards, in the manner shewn and described.
2nd. The fastening and tightening up of the sashes by means of the lever as
aforesaid, as also shewn and described.
3rd. Fastening the sashes by means of copper or iron wire, cords, or other

page_text: imperishable material, working in combination with the fastenings and pullies
applied and fixed to the sashes in the manner described.
In witness whereof, I, the said George Edwards, have hereunto set my hand
and seal, this Tenth day of August, in the year of our Lord One thousand
eight hundred and seventy-seven.
