Worcester, Gentleman, for the Invention of "IMPROVEMENTS IN SLIDING
SASHES, SHUTTERS, OR DOORS."
ealed the 15th July 1859, and dated the 20th January 1859.
PROVISIONAL SPECIFICATION left by the said Samuel Phillips at the
Office of the Commissioners of Patents, with his Petition, on the
20th January 1859.
I, SAMUEL PHILLIPS, of Moseley, in the County of Worcester, Gentleman,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
SLIDING SASHES, SHUTTERS, AND DOORS," to be as follows, that is to say :-
My Invention consists of a simple apparatus to be attached to the edges of
window sashes, shutters, or doors as a substitute for the pulleys, lines, and
weights, and other such contrivances now adopted for the purpose of balancing
and sliding such sashes, shutters, or doors. (a, B,) in the annexed Drawings
are two metal plates, the one marked (a) having screwed pins (c) secured to
it, which pins pass freely through holes in the plate (B), round these pins are
coiled springs (d) regulated in their strength by means of the nuts (E), so that
any reasonable power may be given to the springs. The plate (B) carries the
ratchet roller (f), upon which roller, by reason of its position in the plate (B),
the power of the springs (d) is exerted. Any efficient stop or detent, such
for instance as the click or pawl (9), may be employed to prevent the revo
lution of the ratchet roller in more than one direction. This apparatus may
be used either on one or both edges of a sash or shutter, and should be sunk or
morticed into it, plain friction rollers being employed as an auxiliary wherever
requisite.

by the said Samuel Phillips in the Great Seal Patent Office on the

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
PHILLIPS, of Moseley, in the County of Worcester, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of January, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Samuel Phillips, Her special licence that I, the said Samuel
Phillips, my executors, administrators, and assigns, or such others as I, the
said Samuel Phillips, 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 "IM-
PROVEMENTS IN SLIDING SASHES, SHUTTERS, OR DOORS," upon the condition
(amongst others) that I, the said Samuel Phillips, by an instrument in writing
under my hand and seal, 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 Samuel Phillips, do hereby declare
the nature of the 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 Drawings hereunto annexed, and to the
letters and figures marked thereon, that is to say :-
My Invention consists of a simple apparatus to be attached to window
sashes, sliding shutters or doors, by the use of which pulleys, sash lines and
weights may be dispensed with.
.
The annexed Drawings will serve to illustrate this apparatus and the mode
in which it is to be employed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan of the apparatus seen from the top; Figure 2, a side
elevation; Figure 3, a longitudinal section; Figure 4, a transverse section;

page_text: another form of detent; Figure 7, a plan of the under side of Figure 6;
Figure 8 shews the mode of application.
(A, B,) are two metal plates, that marked (A) having screwed pins (C) firmly
secured to it; these pins (C) pass freely through holes in the plate (B), and
around them are coiled springs (D), which springs may be regulated in
strength by means of the nuts (E), working upon the screwed part of the
pins (C), so that any reasonable power may be given to the springs, and this
power may be varied according to the weight of sash upon which the apparatus
may be employed. The plate (B) carries a ratchet roller (F), upon which
roller by reason of its position in the plate (B), the power of the springs (D)
is exerted, tending to keep the plate (B) in immediate contact with the under
side of the plate (A). The spring click or pawl (G) when a ratchet roller as
at (F) Figure 3 is used, or a wedge and spring in cases where a plain roller
is employed as at (F1, Figure 6), prevents the revolution of the roller in more
than one direction, so that whilst a vertical sash or shutter will run freely
upwards, the dragging of the roller by means of this detent will tend to
prevent the sash falling by its own weight. The ratchet roller and pawl
produce a clicking noise in raising the sash, which may not be objected to in
most instances, as it would give notice of any burglarious attempt to raise
the sash. But in cases where this clicking may be deemed objectionable, the
plain roller and wedge detent, shewn at (Figure 6), will be found more
suitable. The apparatus may be used on one or on both sides of a sash,
and should be sunk or morticed into it, as shewn at Figure 8, plain friction
rollers being employed upon the opposite side when this apparatus is employed
on one side only.
Having thus described the nature of my said Invention, and in what manner
the same is to be performed, I wish it to be understood that that which I
claim is the improvements in sliding sashes, shutters, or doors by the appli-
cation thereto of spring roller apparatus in manner herein more fully set forth
and specified.
In witness whereof, I, the said Samuel Phillips, have hereunto set my
hand and seal, this Eighteenth day of July, in the year of our Lord
One thousand eight hundred and fifty-nine.
SAMUEL PHILLIPS. (L.S.)
