IMPROVEMENTS IN THE CONSTRUCTION AND FITTINGS OR SLIDING WINDOW SLID
Year: 1861

page_text: LETTERS PATENT to Edward Bing, of Ramsgate, in the County of Kent,
Builder, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION AND
FITTINGS OR SLIDING WINDOW SLID
Sealed the 3rd December 1861, and dated the 13th June 1861.
PROVISIONAL SPECIFICATION left by the said Edward Bing at the
Office of the Commissioners of Patents, with his Petition, on the
18th June 1861.
I, EDWARD BING, of Ramsgate, in the County of Kent, Builder, do
hereby declare the nature of the said Invention for. "IMPROVEMENTS IN THE
CONSTRUCTION & FITTINGS OF SLIDING WINDOW SASHES," to be as follows:-
My Invention relates to so fitting & furnishing sliding window sashes that
they may be readily removed from their position for the purpose of cleaning,
repairs, & other purposes, & which may thereby be effected entirely within the
building to which they are fitted.
For this purpose I make the sashes of such width that they pass readily
between the beads forming the grooves of the window in which they slide.
Between the beads I fit strips of wood which are attached to the weighted
cords and slide up and down in manner similar to ordinary sashes; these
sliding pieces are double rebated into the beads or sides of the grooves, so that
they cannot leave their position. The sashes are fitted between these sliding
pieces and rebated thereto; they are hinged at one side to one of these sliding

page_text: pieces, and open inwards, so that when closed they shut against the rebates
and make a tight joint. The beads on the exterior are such as to cover the
joints of the rebates & form a weather covering to the sashes equal to the
ordinary beads. The outer and upper sash I make a little narrower than
the lower one, so that it may be moved on its hinges inwards when both are
lowered; the weight of the sashes when opened on their hinges will keep
the weighted side pieces down on the one side, while to the other side pieces
I fit bolts which answer the double purpose of securing them in the down-
ward position when released from the sashes, & also secure the sashes to the
side pieces. This bolt (one for each sash) I mount on the top of the sash, &
form a socket hole for the point in a suitable position in the side frame of the
window, where it holds it when shot or thrown outwards; when withdrawn
and thrown laterally inwards another part of the bolt (which is fixed on the
top of the side piece) enters the sash & fixes it securely between the window
frames.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Bing in the Great Seal Patent Office on the
18th December 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
BING, of Ramsgate, in the County of Kent, Builder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of June, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of
Ier reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Edward Bing, Her special licence that I, the said Edward Bing,
my executors, administrators, and assigns, or such others as I, the said Edward
Bing, 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 THE CON-
STRUCTION AND FITTINGS OP SLIDING WINDOW SASHES," upon the condition (amongst
others) that I, the said Edward Bing, my executors or administrators, by an
instrument 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 what manner the same was to be performed, and cause the same

page_text: to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Bing, do hereby declare the
nature of my 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, reference being had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say):
My Invention relates to so fitting and furnishing sliding window sashes that
they may be readily removed from their position for the purpose of cleaning,
and which may thereby be effected entirely within the building to which they
aro fitted.
For this purpose I make the sashes of such width that they pass readily
between the beads forming the grooves of the window in which they slide.
Between the beads I fit strips of wood which are attached to the weights by
the cords, and slide up and down in manner similar to ordinary sashes; these
sliding pieces are double rabbeted into the beads or sides of the grooves, so
that they cannot leave their position. The sashes are fitted between these
sliding pieces and rebated thereto; they are hinged at one side to one of the
sliding pieces, and open inwards, so that when closed they shut against the
rebates and make a tight joint. The beads on the exterior are such as to
cover the joints of the rabbets and form a weather covering to the sash equal
to the ordinary beads. The outer and upper sash I make a little narrower
than the lower one, so that it may be moved on its hinges inwards when both
are lowered. The weight of the sashes when opened on their hinges will
keep the weighted side pieces down on the one side, while to the other side
pieces I fit bolts which answer the double purpose of securing them in the
downward. position when released from the sash, and also to secure the sashes
to the side pieces. This bolt (one for each sash) I mount on the top of the
sliding piece, and form a socket hole for the point in a suitable position in
the side frame of the window, where it holds it when thrown outwards; when
withdrawn and thrown inwards another part of the bolt (which is fixed on the
top of the side piece) enters the sash and fixes it securely between the window
Fig. 1 represents an inside view of a window, with parts in teral section
taken in the different planes of the sashes, constructed according to my Inven-
tion; Fig. 2a horizontal section, and Fig. 3 a vertical section of the same;
while Figs. 4, 5, & 6 represent detached views of some of the parts; Fig. 4

page_text: being one of the sashes removed; Fig. 5 an edge view of the same, & Fig. 6
an enlarged detached side view of the bolt for fastening the sashes attached to
a part thereof.
a, a', are the sashes, which, as will be observed, are slightly narrower than
the space between the beads b, b, c, c¹; the inside sash a is fitted to sliding
pieces d, d', fitted between the beads b, c, b, c, being rabbetted into them, as
seen in the horizontal section, so that they are free to slide up & down
therein, but are otherwise held firmly in place; the outside sash a' is similarly
fitted to sliding pieces c, e', rabbetted into beads c, c¹, & outside strips or
weather pieces f; these sliding pieces are each attached to one of the counter-
balance weights h, h, i, &, applied to counterbalance the weight of the sashes,
as usual. The sash a is hinged by a pair of ordinary hinges g; g, to the
strip d, by preference with the joints projecting out from the window, so that
the sash when opened in the manner of a door will be brought out beyond the
level of the bead and may fold flat to the wall, or nearly so, if necessary. The
sashes are connected to the sliding pieces d, e, by bolts k, k, separately seen
at Fig. 6. These bolts act in a double capacity, viz., that of securing the
sash to the sliding piece, so that the whole slides and is counterbalanced as
an ordinary window, and also to fix the sliding pieces d¹ & e' in their places
when the sashes are detached from them. In order to open the sash a on
its binges it is raised a little so as to clear the bottom bead; the bolt k is
then shot or moved from left to right, this movement withdraws part 1 from
its hole or lodgement in sash a, but at same time shoots part 2 of the bolt into
a lodgement in the side frame, seen in the lateral section Fig. 1, which secures
and holds the pieco d in that position; in this way the sash is released and
may be opened on its hinges in the manner of a door, and thus be readily
cleaned on both sides while inside of the room or apartment. In order to
keep the sash from winding I fix a pin a in d¹ to project therefrom and enter
an angular slot in a piece of metal fixed to the sash, as seen in edge view,
Fig. 5; when the sash is closed the pin x enters the horizontal part of the
slot 1, & is then lifted a little in the vertical part & bolt K shot to its lodge-
ment formed in the sash for part 1. The upper sash a' is similarly fitted &
furnished, and is lowered to about same position as the other sash a to be opened
on its hinges, its bolt k serving the purposes before explained. The sashes
at their junction with their pieces d, e, have a return rabbet or fillet entering
a groove in those pieces, as seen in the horizontal section, this, however, may
be dispensed with. It will be readily understood that the sliding pieces
d, d', & e', may be removed from their position by removing the beads of the
window as required for removing ordinary sashes. The bolts k, k, or rather

page_text: sockets in which they are held & slide, are fixed on the pieces d', e¹; a recess
is cut for the bolt in the upper part of the window frame to allow the upper
sash to go close up. These sashes may be fixed when closed by any of the
ordinary fastenings.
Having described the nature of my Invention, & the manner of perform-
ing the same, I declare that what I claim as my Invention, to be protected
by the herein-before in part recited Letters Patent is, fitting and applying
window sashes in position on hinges on one side, so as to open, as described,
for cleaning and other purposes; as also the means of securing them in the
closed position by the bolts k, which effect the fixing of the sash and the
release of the sliding piece simultaneously, or, on the contrary, secure the
sliding piece & release the sash, as may be desired, and as herein-before
described.
In witness whereof, I, the said Edward Bing, have hereunto set my
band and seal, this Twelfth day of December, in the year of our
Lord One thousand eight hundred and sixty-one.
EDWARD BING. (L.S.)
