IMPROVEMENTS IN WINDOW SASH HOLDERS
Year: 1874

page_text: LETTERS PATENT to Raymond Fletcher, of Derby, Painter, for the
Invention of "IMPROVEMENTS IN WINDOW SASH HOLDERS."
Sealed the 11th December 1874, and dated the 27th June 1874.
PROVISIONAL SPECIFICATION left by the said Raymond Fletcher at
the Office of the Commissioners of Patents, with his Petition, on
the 27th June 1874.
I, RAYMOND. FLETCHER, of Derby, Painter, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN WINDOW SASH HOLDERS,"
to be as follows:-
My improved holders are equally applicable to the window sashes of
houses, railway carriages, cabs, and wherever a sliding sash is used, and
consists of a plate to the back of which is hinged a box. From the
lower end of the plate a spring projects, which pressing upon the back of
the box presses it close to the plate. The box is slotted on each side, in
which slots the axle of a truck or runner is free to revolve or slide.
Inside the bottom of the box is a pieco-of-india-rubber. One such box
and plate is let in flush with the frame on each side a sash, the
runners
دين

page_text: will then allow the sash to be casily raised, and will securely hold it
where placed as the runners drop in the slots and are wedged fast by the
india-rubber; but upon extra pressure being applied the springs will
give way and allow the sash to be lowered as required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Raymond Fletcher in the Great Seal Patent Office
on the 23rd December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RAYMOND
FLETCHER, of Derby, Painter, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of June, in the year of
our Lord One thousand eight. hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors, givo
and grant unto me, the said Raymond Fletcher, Her special licenso
that I, the said Raymond Fletcher, my executors, administrators, and
assigns, or such others as I, the said Raymond Fletcher, 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, tho
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN WINDOW SASH HOLDERS," upon the condition (amongst others) that
I, the said Raymond Fletcher, 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 bo performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after tho date of the said Letters
Patent.
NOW KNOW YE, that I, the said Raymond Fletcher, 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:-

page_text: The object of my present Invention is to hold or sustain window and
other sliding sashes, doors, and the like, when opened or raised fully or
at any desired height, without the aid of the ordinary sash lines, pullies,
and weights.
፡፡፡
My improved sash holders are equally applicable to the window
sashes of houses and other buildings, railway and other carriages, and
wherever a sliding sash or door is used.
In order that my said Invention may be more easily and more fully
understood, and be more readily performed, I now proceed to explain
the same with the aid of the accompanying Drawing, which forms part
of this Specification, reference being made thereto by the numerals and
letters marked thereon, and which reference applies to each Figuro of
the said Drawing where the same indox numerals and letters appear.
Figure 1 is an elevation of a pair of window sashos and frame, showing
the positions of my improved holders when fixed in place.
Figure 2 is a side clevation, and Figure 3 a front clevation of the said
holders drawn full size, as are also Figures 4, 5, and 6.
Figure 4 is a front olevation of another holder, adapted to carriage
and other similar windows or openings; Figure 5 is a vertical section
of the samo, on the line A, B, Figure 4; Figure 6 is a back elevation of
the same.
"
My improved holders are constructed as follows:-In a metal box a I
mount a roller or pulley of wood or other suitable material. To the
box & I attach one end of a steel spring c, the other end being "let in
or sunk in the frame d, to which frame it is securely fixed. A recess is
formed in the frame & large enough to allow the spring c to act, and
also to admit the metal box a and the roller b, so that the periphery of
the said roller may be pressed flush with the face of the frame d, as
shewn in Figures 1 and 2. The axle e of the roller 6 does not work in
a confined bearing, as customary, but is placed in a larger opening ƒ cut
or formed in each side of the box a. Under the roller or pulley 6 I
place a cushion of ordinary or vulcanized caoutchouc g. If desired' in
some cases a sunken recess may be properly formed in the window
frame, either lined or not with metal, and thus save the cost of the
box, but I prefer to use a box or case.

page_text: sash may press and slido against the roller or pulley 6; but the said
holders may be fixed in the side rails of the sashes.
$
When either sash is raised the pressure of such sash forces the roller b
clear of the cushion g, thereby enabling such roller to turn or act freely,
and thus allow the sash to be opened with case. On leaving the sash in 5
the position desired its weight presses or forces the roller & upon tho
cushion 9, which prevents the said roller rotating, and thereby holds or
sustains the sash in such desired position. To close a lower sash'a small
additional force is only required to be exorted upon it to counteract the
pressure of the springs, and push the roller flush, or nearly so, with 1
the frame'd, when the sash is easily closed or placed in any other desired
lower position.
In opening or lowering an upper sash a small additional force is
required, as in closing a lower sash. The weight of such sash causes
the roller to rest upon the cushion 9 (these cushions are in all cases 1
placed under the rollers) when the said roller ceases to rotate and
the sash is sustained as previously heroin described, see Figures 1, 2,
and 3.
For carriage and other small windows or openings my improved
holders are formed as shewn in Figures 4, 5, and 6, the main principles 2
being the same in each case; but in the latter case the box a is hinged
or jointed at / to a plate i, which plate is fixed in and flush with the
face of the window frame. The steel spring c is not attached to the box
or case a but acts upon or against it, see Figure 5.

By the adoption of my improved holders there will be a saving in
both labour and material in the construction of window frames. They
are casily fixed and cannot get out of order as does the arrangement
with lines, pullics, and weights. By simply removing the beading from
one-side-of-the-frame-sashes-can-be-promptly-removed, laid-on-a-table,
cleaned, painted; and repaired, thus, avoiding the great risk and cost of
using ladders for such purposes. Tho holders also prevent the shaking
of windows in windy weather, the sashes being firmly held by the
apparatus...

Having thus fully explained the nature of my said Invention and the
method of performing the same, I wish it to be understood that I do a
not confine myself. to the dimensions of any of the details now illustrated,
nor to forms thercof, as they admit of considerable variation according

page_text: to the size, weight, and other peculiarities of the sliding bodies to which
the apparatus is to be attached; but I claim as my Invention, and
desire to secure by the herein-before mentioned in part recited Letters
Patent, the method of holding or sustaining sliding sashes and other
similar sliding bodies in any desired position, whether open, partially open,
or closed, substantially as herein described and shewn in the Drawing.
In witness whercof, I, the said Raymond Fletcher, have here-
unto set my hand and scal, this Twenty-second day of Decomber,
in the year of our Lord One thousand eight hundred and seventy-
four.
