Year: 1865

page_text: LETTERS PATENT to Henry Newman, of Aston, near Birmingham, in the
County of Warwick, Manufacturer, for the Invention of "IMPROVEMENTS
IN SUSPENDING OR SUPPORTING WINDOW SASHES AND SLIDING SHUTTERS."
Sealed the 3rd April 1866, and dated the 23rd October 1865.
PROVISIONAL SPECIFICATION left by the said Henry Newman at
the Office of the Commissioners of Patents, with his Petition, on the
23rd October. 1865..
I, HENRY NEWMAN, of Aston, near Birmingham, in the County of
Warwick, Manufacturer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN SUSPENDING OR SUPPORTING WINDOW SASHES AND
SLIDING SHUTTERS," to be as follows:-
My Invention consists in arranging the parts of mechanism for sus-
pending or supporting window sashes and sliding shutters in the manner
herein-after explained, whereby the said mechanism is made to work with
great uniformity and ease. By the use of my Invention the lines or cords
and balance weights by which window sashes and sliding, shutters are
ordinarily suspended are dispensed with.
I will describe my Invention with reference to the suspension of a
window sash. On either side of the sash I make two or more rectan-
gular recesses, the recesses in one side of the sash being opposite

page_text: those in the other side of the sash. In each of the said recesses I place
mechanism for sspending or supporting the sash, the said mechanism
consisting of a plate or carriage, on one side of which a roller is
mounted in bearings. At the opposite side of the plate or carriage
to that at which the roller is situated a bow spring is fixed. The mechanism
described is placed in each of the recesses in the sides of the sash, the
rollers being placed outwards and the springs bearing against the bottom
of the said recesses. The said mechanism only requires to be dropped
into the recesses when the sash is ready to be fixed in the window frame.
On placing the sash provided with my Invention in the window frame the
springs at the inner sides of the plates or carriages are compressed, and the
rollers are made to bear forcibly against the sides of the window frame by
the elasticity of the said compressed springs, so that on raising or lowering
the sash the said sash is suspended in the position at which it is placed by
the friction of the rollers against the sides of the window frame.
In applying my Invention to sliding shutters, the mechanism by which
the said sliding shutters are suspended is arranged in the manner described
with respect to window sashes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Newman in the Great Seal Patent Office on the
21st April 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
NEWMAN, of Aston, near Birmingham, in the County of Warwick, Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of October, in the year
of our Lord One thousand eight hundred and sixty-five, in the twenty-
ninth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Henry Newman, Her special licence that I,
the said Henry Newman, my executors, administrators, and assigns, or
such others as I, the said Henry Newman, 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 SUSPENDING OR SUPPORTING

page_text: WINDOW SASHES AND SLIDING SHUTTERS," upon the condition (amongst
others) that I, the said Henry Newman, my executors or adminis-
trators, 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 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 Henry Newman, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
My Invention consists in arranging the parts of mechanism for
suspending or supporting window sashes and sliding shutters in the manner
herein-after explained, whereby the said mechanism is made to work with
great uniformity and ease. By the use of my Invention the lines or cords
and balance weights by which window sashes and sliding shutters are
ordinarily suspended are dispensed with.
I will describe my Invention with reference to the suspension of a
window sash. On either side of the sash I make two or more rectangular
recesses, the recesses in one side of the sash being opposite those in the
other side of the sash. In each of the said recesses I place mechanism for
suspending or supporting the sash, the said mechanism consisting of a plate
or carriage, on one side of which a roller or rollers are mounted in bearings.
At the opposite side of the plate or carriage to that at which the roller or
rollers are situated a bow spring is fixed. The mechanism described is
placed in each of the recesses in the sides of the sash, the rollers being
placed outwards and the springs bearing against the bottom of the said
recesses. The said mechanism only requires to be dropped into the
recesses when the sash is ready to be fixed in the window frame. On
placing the sash provided with my Invention in the window frame the
springs at the inner sides of the plates or carriages are compressed, and
the rollers are made to bear forcibly against the sides of the window frame
by the elasticity of the said compressed springs, so that on raising or
lowering the sash the said sash is suspended in the position at which it is
placed by the friction of the rollers against the sides of the window frame.
In applying my Invention to sliding shutters the mechanism by which
the said sliding shutters are suspended is arranged in the manner described
with respect to window sashes.

page_text: Having explained the nature of my Invention, I will proceed to describe
with reference to the accompanying Drawing the manner in which the
same is to be performed.
Figure 1 represents in front elevation a window frame and its sashes, to
which my Invention is applied; Figure 2 is a section of the same; and
Figure 3 is an edge view of one of the sashes; Figures 4, 5, and 6,
represent separately on a larger scale the suspending mechanism, Figure 4
being a side elevation; Figure 5, a plan, and Figure 6, a section. The
same letters indicate the same parts in each Figure. The mechanism,
Figures 4, 5, and 6, by which the sashes are suspended in the window
frame, consists of a plate or carriage a, to either end of which a roller 6 is
connected, the said rollers being capable of rotating freely on their axes c,
carried by the bearings d on the plate or carriage a.. The periphery of
each roller 6 is covered by preference with a band of vulcanized india-
rubber or other yielding material marked e, but the said rollers may be
made wholly of metal. On one side of the plate or carriage a a bow
spring is connected by the pins and slots at g. On either side of the
sashes h, i, I make two (or more) rectangular recesses k, k, the recesses in
one side of the sash being by preference opposite those in the other side
of the sash, as illustrated in the Drawing. In each of the recesses k I
place the suspending mechanism represented in Figures 4, 5, and 6, the
said mechanism being placed in the recesses in the position best seen in
Figure 2, that is, the rollers b, b, are placed outwards, and the springs f
made to bear against the raised part at the bottom of the said recesses.
The suspending mechanism only requires to be dropped into the recesses
k, when the sashes are ready to be placed in the window frame l. When
the sashes provided with my Invention are placed in the window frame 1,
the springs fat the inner sides of the plates or carriages a are compressed,
and the rollers c, c, are made to bear forcibly against the inner sides of the
window frame by the elasticity of the said compressed springs. On
raising or lowering the sashes, they are suspended at the position at which
they are placed by the friction produced by the springs f
The application of my Invention to sliding window shutters does not
differ in any essential respect from its application to window sashes herein-
before described and illustrated in the Drawing.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I
do not limit myself to the precise details herein described, as the same
may be varied without departing from the nature of my Invention;

page_text: but I claim as my Invention, suspending or supporting window sashes
and sliding shutters by means of mechanism, the parts of which are con-
structed and arranged substantially in the manner herein-before described
and illustrated in the accompanying Drawing.
In witness whereof, I, the said Henry Newman, have hereunto set
my hand and seal, this Nineteenth day of April, in the year of our
Lord One thousand eight hundred and sixty-six.
Witness,
GEORGE SHAW.
