EDWARD THORP 53 Saint Johns Street Folkestone Kent do hereby declare the
nature of this invention to be as follows:-
:―
Revolving Balance opens and closes sashes simultaneously, Self acting Rachets to
retain sashes at any elevation, two shifting slide pieces to take sashes out when
required Revolving Balance secured to frame and is a wheel with eight cogs acting
in perforated irons secured to each sash the Rachets retain the top sash while the
bottom sash is being removed release or shift the slide pieces which are secured to
bottom sash and take the sashes out these slide pieces are kept in their position when
in work by iron buttons secured to the edge of slides.
The Revolving Balance (A) is a wheel with eight cogs revolving on an axle fixed
to the window frame (X) acting in perforated irons (B) which are secured to the
sashes. The Balance wheel (A) opens and closes the sashes with facility and ease.
Rachet (C) self acting when closing the sashes and retains the sashes that they
cannot be opened wider by any body out side of the house. The window may be left
partially open quite safe at any elevation. Rachet (C) also retains the top sash while
the bottom sash is being removed. Rachet (C) has a loose pully wheel (D) for
line (E) fastened to Rachet (C) to release Rachet (C) from perforated irons (B) when
the sashes are required to be opened this line (E) passes over two loose pully wheels
as (D) secured at the top of frame (X) and retained by an holdfast while required
when line (E) is loosed. Rachet (C) fastens the sashes of itself. Spring (f) acts on
Rachet (C) for perfect safety.
Shifting slide piece (G) secured to bottom sash by screws and slotted (H) for
shifting it out of groove (I) made in sash frame (X) for them to slide up and down
when the sashes are in use. Iron button (J) is secured to edge of slide piece (G). A
chase (K) is made in sash for Button (J) to work in thus retaining slide piece (G) in
the groove (I) while the sashes are being used. Sash Knobs (L) to shift the
slide (G) out of groove (I) when the bottom sash is to be taken out.

out of chase (K) and with the sash knobs (L) shift the slide piece (G) out of groove (I)
in frame (X) releases the bottom sash then remove the sash into the room release
Rachet (C) from perforated iron (B) as shown above and take the top sash out.
Tongue (M) in frame (X) is let into frame (X) the depth of top sash which is
grooved (N) to saddle tongue (M) in frame (X).
Outside lining (0) as in present use merely for safety while sashes are being taken
out or replaced.
Deep Sill piece (P) to exclude draft at the bottom of window when the top sash is
lowered any distance to four inches.
Additional Sill piece (R) folds up or down as may be required to exclude draft at
the bottom of window when the top sash is lowered any distance to the space of eight
inches.
.Perforated irons (B) shews two different forms of perforated irons (B) to suit
different kinds of windows and for rearranging of sashes that are in use at the present

Windows.
EDWARD THORP, 53 Saint John's Street, Folkestone, Kent, Carpenter & Joiner, do
hereby declare the nature of this invention and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement:-
The drawings referred to in this specification were left with the Provisional.
Sliding Window sashes open and close simultaneously on Revolving Balance (A)
which is a wheel with eight cogs revolving on an axle in a frame of wood, iron, or
any hard metal or other material fixed to Window Frame (X), acting in Perforated
Plates (B). These same Perforated Plates (B), are secured to the sashes; the Balance
Wheel (A) opens and closes the sashes by applying the hand and lifting the bottom
sash to open the window, and by pressing the same down, to close the window.
Rachel (C) self acting in Perforated Plates (B) when closing the sashes, and retains
the sashes; so that they cannot be opened wider by any means from the outside. The
Window may be partially open, and be quite safe at any elevation. Rachet (C) also
retains the top sash, while the bottom sash is removed. Rachet (C) has a loose Pully
Wheel (D) for Line (E) fastened to Rachet (C), to release Rachet (C) from Perforated
Plates (B) when the sashes are required to be opened. This Line (E) passes over two
loose Pully Wheels as (D) secured at the top of Window Frame (X) held by a
holdfast while required; when Line (E) is loosed, Rachet (C) fastens the sashes of
itself, by means of Spring (f), which acts on Rachet (C) for perfect safety.
Shifting Slide Pieces (G) are secured to bottom sash by screws, or by a pin with
socket for screw, fixed to sash; the Slide Pieces (G) are slotted (H) for shifting them
out of Grooves (1) Grooves (1) are made in Sash Frame (X) for sashes to slide up
and down when in use. Buttons (J) are secured to the edge of Slide Pieces (G), a
chase (K) is made in sash for Buttons (J) to work in; thus retaining the Slide
Pieces (G) in the Grooves (1), while the sashes are being used.
Sash Knobs (L) are
to shift the Slide Pieces (G) out of Grooves (I), when the bottom sash is to be taken out.
Tongue (M) in Frame (X), is let into Frame (X) the depth of top sash, the said
top sash being grooved to saddle Tongue (M) in Frame (X).
Outside Lining (0) as in present use, merely for safety while the sashes are being
taken out or replaced.
Deep Sill Piece (P) is fixed, and forms part of Sash Frame (X), to exclude draft
at the bottom of window, when the top sash is lowered any distance to four inches.
Additional Sill Piece (R), is rebated and hung with brass butt hinges to Deep Sill
Piece (P), to fold up or down as required, to exclude draft at the bottom of window
when the top sash is lowered any distance to the space of eight inches; and is kept in
position by means of small sliding bolts running into Frame (X).
Perforated Plates (B) shew two different forms of Perforated Plates (B), to suit
different kinds of windows, and for rearranging of sashes that are in use at the present
time.
Method of taking the sashes out of Sliding Window

page_text: Knobs (L) shift the Slide Pieces (G) out of Grooves (I) in Frame (X); this releases
the bottom sash, which can then be lifted into the room.
TOP SASH.
Place the hand under the sash, and with Line (E) remove Rachet (C) from
Perforated Plates (B), and lower the sash, which can then also be lifted into the room.
Method of replacing the sashes :-
TOP SASH.
Release Line (E) connected with Rachet (C); take the sash and put in the
Frame (X), and lift the sash quite up to the head of frame (X), and Rachet (C) will
retain it in that position.
BOTTOM SASH.
Put the sash into position in Frame (X) and with the Sash Knobs (L) shift the
Slide Pieces (G) into Grooves (I); turn Buttons (J) into Chases (K) in sash, and
the Sliding Window is again complete for use.
I would wish it to be understood that I do not limit myself to any number of Cogs
on Balance Wheel (A).
The features of Novelty are as follows:-
That houses may be ventilated with ease where ventilation is most effective; for by
simply raising the bottom sash, the top sash may be opened any distance from half to
four inches; and by means of the additional Sill Piece to eight inches, and still be
entirely free from draft at the bottom, at the same time being perfectly safe at any
elevation.
That a domestic servant can with ease take the sashes into the room for the purpose
of cleaning, and thereby doing away with the dangerous practice of standing outside
the window.
That this process also prevents the destruction of paint, as there are no sash lines to
be renewed.
That this process does away with sash lines, sash weights, and sash pullies.
That the windows are free from all noise when the wind blows.
That the sashes fasten themselves in such a manner, that it would be an extremely
difficult matter for a burglar to effect an entrance.
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
1st. "A" Patent for "A method of balancing and holding the sashes of Sliding
Windows."
2nd. The Revolving Balance Wheel with cogs, frame for axle, and the Perforated
Plates in both forms; the Wheel, Frame and Plates to be made either of wood, iron,
or any hard metal or other material.
3rd. The Self acting Rachet with loose Pully wheels, the Line connected with
Rachet, and Spring acting on Rachet; also additional Rachet on opposite side of
window with or without Spring.
4th. The Tongue in frame for top sash to slide over, the Deep Sill Piece, and
additional Sill Piece.
