page_text: LETTERS PATENT to John Holmes, of Northampton, in the County
of Northampton, Moulder, for the Invention of "AN IMPROVED SASH
HOLDER BY MEANS OF WHICH THE SASH MAY BE HELD IN ANY REQUIRED
POSITION WITHOUT THE AID OF SASH LINES, WEIGHTS, OR PULLEYS, OR SUCH
LIKE CONTRIVANCES."
Sealed the 10th August 1869, and dated the 13th February 1869.
PROVISIONAL SPECIFICATION left by the said John Holmes at the
Office of the Commissioners of Patents, with his Petition, on
the 18th February 1869.
I, JOHN HOLMES, of Northampton, in the County of Northampton,
Moulder, do hereby declare the nature of the said Invention for "Ax
IMPROVED SASH HOLDER BY MEANS OF WHICH THE SASH MAY BE HELD IN ANY
REQUIRED POSITION WITHOUT THE AID OF SASH LINES, WEIGHTS, OR PULLEYS, OR
SUCH LIKE CONTRIVANCES," to be as follows:-
The object of this Invention is sufficiently explained in the title,
the Invention consisting of the apparatus herein-after described by
means of which sash lines, weights, and pulleys, and such like oon-

page_text: trivances for holding the sash in any required. position are dispensed
with.
The
A metal frame of a suitable size being provided an aperture sufficiently
large to take the roller is made therein in the usual manner.
said roller works upon a pin, also in the usual manner, but instead
of this pin working in a fixed centre a slot or groove in the side
bracket is made. The said roller is kept in its proper position by
means of a flat spring, one end of which is affixed to the bottom of
the inner part of the frame, the other or free end being shaped to fit
or nearly to fit the roller and presses against it.
The operation of my improved sash holder is as follows :—The
apparatus herein-before described is fixed either to the window sash
or to the window frame. When the sash is raised or lowered to the
desired position it is caused to remain there by reason of the spring
herein-before described pressing upon the roller, which in its turn comes
against the sash or frame, as the case may be, and the sash is thus
securely held in the required position. In the case of heavy window
sashes two or more of my improved sash holders may be used instead
of a single one if found necessary.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Holmes in the Great Seal Patent Office on
the 12th August 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HOLMES, of Northampton, in the County of Northampton, Moulder,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of February, in the year
of our Lord One thousand eight hundred and sixty-nine, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Holmes, Her special.

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 "AN IMPROVED
SASH HOLDER BY MEANS OF WHICH THE SASH MAY BE HELD IN ANY REQUIRED
POSITION WITHOUT THE AID OF SASH LINES, WEIGHTS, OR PULLEYS, OR SUCH
LIKE CONTRIVANCES," upon the condition (amongst others) that the
said
executors or administrators, by an instrument in
writing under 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 John Holmes, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement :-
1. The nature of my said Invention is as follows:-I adopt a metal
frame of a suitable size, with an aperture sufficiently large to take
the roller hereafter described being made or provided thereon. The
said roller works upon a pin, but instead of this pin working on a
fixed centre a slot or groove in the side bracket is made, and the said
roller is kept in its proper position by means of a spring, one end of
which is affixed to the bottom of the inner part of the frame, the other
or free end being shaped to fit or nearly to fit the roller and press.
against it.
The operation of my improved sash holder as the same would usually
be applied is as follows:-The apparatus herein-before described is fixed
either to the window sash or to the window frame. When the sash is
raised or lowered to the desired position it is caused to remain there
by reason of the spring herein-before described pressing upon the roller,
which in its turn comes against the sash or frame, as the case may be,
and the sash is thus securely held in the required position. In the
case of heavy window sashes two or more of my improved sash holders
may if required be used instead of a single one.
(II.) Having now particularly described and ascertained the nature of
my said Invention, I will now proceed to more particularly describe
and ascertain in what manner the same may be performed and carried
out in practice, reference being had to the accompanying Drawings.

page_text: DESCRIPTION OF THE DRAWINGS ILLUSTRATIVE OF MY INVENTION.
Figure 1, side view; Figure 2, section; Figure 3, back view; Figure 4,
front view of a sash holder constructed in accordance with my said
Invention; Figure 5, section through A, B, Figures 1, 2, 3, and 4. The
following letters of reference refer to the same parts in Figures 1, 2,
3, 4, and 5, so far as such parts are shewn in the said Figures. C, frame
of sash holder; D, aperture in frame (C); E, roller; F, pin on which
roller (E) works; G, brackets; H; groove in bracket in which pin (F)
works; I, flat spring; J, screw, and K nut for securing end of spring (I)
to frame; L, spring washer, which being screwed down upon the end
of the spring (I) the power of the spring is increased, and such power
may be still further increased by increasing the length of the washer (L),
and of course the spring power may be lessened by shortening, the
washer (L), or by relieving the pressure of the spring washer (L) on
the spring (1) by unscrewing the nut (K). This arrangement therefore
renders the sash holder adjustable to compensate for wear and tear, or
to make it adaptable to different sized windows.
In fitting sashes with my sash holder the sashes should be fitted
carefully so that the space may be equal (parallel) all round between
the pully stile and sash. The horns of the top sash should be left on.
A block; should be fitted at top of the frame on the "pulley" stile
between the parting bead and inside bead, in size about two inches
long, and of somewhat less thickness than the parting bead, or of such
other dimensions as according to the size of the sash and window frame
and the position in which my spring roller is inserted into the frame
or stile as will prevent the bottom sash being so far pushed up as to
be entirely removed from the action of the roller. In fixing sash holders
in "pulley" stiles" for top and bottom sashes the centre of the roller
should be level with the centre of meeting rail when the sashes are
fastened, and a recess should be provided at that point of the sash
stile for the projecting portion M. of the roller, so as to relieve the
spring from strain when the sashes are closed. When the sash holders
are let into the sash stiles instead of the pulley stiles, the position of
the roller should then be in the centre of the height of the sash. It
is preferable however to let the sash holders into the "pulley" stiles.
Having now particularly described and ascertained the nature of
my said Invention, and in what manner the same may be performed

page_text: and carried out in practice, I hereby declare that I claim, the Invention
of "An Improved Sash Holder by means of which the Sash may be
held in any required Position without the Aid of Sash Lines, Weights,
or Pulleys, or such like Contrivances," as herein described and illus-
trated by the accompanying Drawings, it being understood that I do
not claim the mere details of construction per se and apart from the
purposes of my said Invention, nor do I limit myself to the precise form
and details described and illustrated,
In witness whereof, I, the said John Holmes, have hereunto set
my hand and seal, this Ninth day of August, in the year of our
Lord One thousand eight hundred and sixty-nine.
