page_text: LETTERS PATENT to Edward Vansittart Neale, of Church Row,
Hampstead, in the County of Middlesex, for the Invention of
"IMPROVED METHODS OF GOVERNING AND ARRESTING THE MOTIONS OP
SLIDING AND OF HINGED OR SWINGING WINDOWS, DOORS, AND OBJECTS, AND
OP ROTATING Shafts, Rods, and OBJECTS.”
PROVISIONAL SPECIFICATION left by the said Edward Vansittart
Neale at the Office of the Commissioners of Patents, with his
Petition, on the 3rd November 1871.
I, EDWARD VANSITTART NEALE, of Church Row, Hampstead, in the
County of Middlesex, do hereby declare the nature of the said Invention
'IMPROVED METHODS OF GOVERNING AND ARRESTING THE MOTIONS OF SLIDING
AND OF HINGED OR SWINGING WINDOWS, DOORS, AND OBJECTS, AND OF ROTATING
SHAFTS, RODS, AND OBJECTS," to be as follows:-
for
The Invention comprises the governing the sliding motion of windows,
doors, and objects by an endless belt, strap, or cord for handling or

page_text: moving them, attached in one part of its length to the object and passing
over rollers or shafts, and the arresting such motion by a clutch applied
to one of the rollers or shafts; also the arresting the motion of hinged
or swinging windows, doors, and objects by a jointed arm connecting
them with a governing rod or shaft parallel to the pin or axis of the 5
joint, and which (the governing rod) is furnished with a clutch by which
its own angular or turning motion is arrested; and also the arresting the
motion of rotating shafts, rods, and objects by a clutch consisting of two
members fitting with engaging surfaces, in general terms conical, one
within or against the other, but the so-called conical engaging surfaces 1
external of one member and internal of the other, having each of them
symmetrical tapering flutings or alternate projections and sinkings upon
them.
The following examples explain the manner in which the Invention is
to be performed, the governing endless belt to be preferably of strong 1
webbing or material not liable to yield or stretch.
For railway carriage windows leather is convenient, and a buckle is
sometimes to be provided for tightening as required. A lug projecting
from the belt and of same material or of wood will serve as a handle.
For house windows the weighting of the belt on one side of the rollers 2
will serve as a counterweight to the windows; the governing rod to be
so placed and the jointed arm so connected thereto and to the hinged or
swinging window, door, or object as to allow the arm to clear obstructing
projections if any, the arm being if necessary curved for the purpose, and
if desired made to fold on itself when disconnected.
A clutch can be applied to one roller or shaft (for governing endless
belt) or to the governing rod (for jointed arm) as the case may be. I
consider the clutch specially herein set forth convenient for either
application. One member of the said clutch to be made to slide or
move towards or away from the other as required, and sometimes the
one to have a square fitting on the shaft; the other, excepting when they
are engaged, being allowed to turn freely.

In pursuance of the conditions
the Letters I atent,
filed by the said Edward Vansittart Neale in the Great Seal Patent
Office on the 2nd May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
VANSITTART NEALE, of Church Row, Hampstead, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of November, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Vansittart Neale, Her special
licence that I, the said Edward Vansittart Neale, my executors, adminis-
trators, and assigns, or such others as I, the said Edward Vansittart Neale,
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 "IMPROVED
METHODS OF GOVERNING AND ARRESTING THE MOTIONS OF SLIDING AND OF HINGED
OR SWINGING WINDOWS, DOORS, AND OBJECTS, AND OF ROTATING SHAFTS, RODS, AND
ОBJECTS," upon the condition (amongst others) that I, the said Edward
Vansittart Neale, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and scals, 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 Edward Vansittart Neale, 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 :—
The Invention comprises the governing the sliding motion of windows,
doors, and objects by an endless belt, strap, or cord for handling or
moving them, attached in one part of its length to the object and
passing over rollers or shafts, and the arresting such motion by a clutch

page_text: applied to one of the rollers or shafts; also the arresting the motion of
hinged or swinging windows, doors, and objects by a jointed arm con-
necting them with a governing rod or shaft parallel to the pin or axis of
the joint, and which (the governing rod) is furnished with a clutch by
which its own angular or turning motion is arrested; and also the
arresting the motion of rotating shafts, rods, and objects by a clutch
consisting of two members fitting with engaging surfaces, in general
terms conical, one within or against the other, but the so-called conical
engaging surfaces external of one member and internal of the other,
having each of them symmetrical tapering flutings or alternate pro-
jections and sinkings upon them.
The following examples explain the manner in which the Invention is
to be performed, the governing endless belt to be preferably of strong
webbing or material not liable to yield or stretch.
For railway carriage windows leather is convenient, and a buckle is
sometimes to be provided for tightening as required. A lug projecting
from the belt and of same material or of wood will serve as a handle.
For house windows the weighting of the belt on one side of the
rollers will serve as a counterweight to the windows; the governing rod
to be so placed and the jointed arm so connected thereto and to the
hinged or swinging window, door, or object as to allow the arm to clear
obstructing projections if any, the arm being if necessary curved for the
purpose, and if desired made to fold on itself when disconnected.
A clutch can be applied to one roller or shaft (for governing endless
belt) or to the governing rod (for jointed arm) as the case may be. I
consider the clutch specially herein set forth convenient for either
application. One member of the said clutch can be made to slide or
move towards or away from the other as required, and sometimes the
one to have a square fitting on the shaft; the other, excepting when
they are engaged, being allowed to turn freely.
The application of an endless belt or strap for governing the motion
of a carriage window or blind is shewn in Figures 1, 2, and 3, which
also illustrate another part of my Invention, namely, the arresting the
motion of rotating shafts, rods, or other objects by a clutch consisting
of two members fitting with engaging surfaces which are in general
terms conical, one within the other, the so-called conical engaging
surfaces external of. the one and internal of the other, having each of

page_text: them symmetrical tapering flutings or alternate projections and sinkings
upon them.
Figure 1 is a sectional elevation, and Figure 2 tranverse section of
this application; Figure 3 shews in section the position of the clutch
when engaged. a is part of the door of the carriage; b, b', are rollers,
over which the endless belt passes, which are furnished with rims; c is
the belt, the connecting part being shewn by dotted lines in Figure 1;
d, also shewn by dotted lines in Figure 1, is a buckle by which c can bo
tightened if requisite; e, e¹, are supports attached to a plate fixed on or
let into the window case a, between which support 6 & 6' work; f is a
conical cup having tapering engaging interior surfaces, which cup forms
the termination of the axis of 6 on one side; g is a conical bolt with
corresponding surfaces indicated by the lines on it in Figures 1 and 3
capable of rotating on an axis i, which passes through the support h;
j is a spring attached to hand passing round i, by which g is forced
against when the spring is not drawn back; k is a lever or handle
fixed on i; by partially turning such lever and pulling it back g is
drawn out so as to compress j, which is then held in this position by a
pin fixed on i pressing against h; by raising the lever so as to turn i
one quarter turn is brought opposite a slot m, as shewn, thereby
allowing g to be pressed against f. A stop, not shewn in the Figures,
should be placed so as to prevent k from passing the point where I can
enter into m; n is the window moving in the hollow o left in the door,
to the bottom of which 6' is attached by a plate p and screws passing
through it. The part of the strap which passes through the buckle may
be used to draw the window up if the belt is visible in the interior of the
carriage. If it is concealed behind the lining or pockets the window
may be raised either by a handle attached to it at top or by a band
attached to it at bottom passing between it and the belt, and falling over
the latter at top.
To use the apparatus draw up the window to the desired height, and
turn the lever k till it stops. The window will immediately fasten itself
by the action of the clutch. It may be set free by drawing the lever
back and turning it round to its former position. As the window can
be always firmly fixed by the clutch at the desired height it may be
made to slide in a closely fitting groove, by which the liability to
shake may be greatly lessened.
The belt may be made of any material not easily liable to stretch. ·

page_text: such as leather. Such a belt may also be applied to regulate the sliding
motion of house windows, in which case the employment of a clutch to
arrest the motion may be dispensed with by providing the side of the
belt opposite to the window with pockets filled with shot or some other
heavy material, so as to counterbalance the weight of the window, the 5
interval between the rollers being sufficient to prevent any liability in
tho weighted part of the belt to be drawn over the rollers. Figure 4
shews such a belt applied to the lower division of a sliding window, the
framework by which the belt and rollers would be concealed when used
being removed. a is the window frame; b, the belt; c, a ring, by 1
passing through which 6 may be attached to a at bottom; d, a rack
similar to that employed to fasten the cords of window blinds, by which
6 may be connected with a at top in any way which will allow it to be
easily disengaged. Between c and d the belt is omitted for the greater
convenience of attaching it to the window, because in this part the 1
frame practically supplies its place; e, e¹, are the rollers; f is the
weighted part of the belt. In applying the belt to the upper division of
a window the position of the weighted part must be reversed.
.
Figures 5 and 6 illustrate in the case of an outside blind or shutter
the application of my Invention to arrest the motion of hinged or 2
swinging windows, doors, and other objects by means of a jointed arm
connecting them with a governing rod furnished with such a clutch as
has been described by which its own angular or turning motion is
arrested. Figure 5 is a plan; Figure 6, a sectional elevation. In these
Figures a is the jointed arm; b, the joint; c, a pivot or ring by which 2
one arm is attached to the blind d; e, the top of a pin placed in the
centre of the axis of a; g, a box forming this axis, and which has at
top a neck / turning in a collar attached to the plate j, which is fixed
to the window sill, and has at bottom a conical cup k furnished with
internal engaging surfaces, and working in a collar also attached to 3
the plate jabove k; m is a ring surrounding g by which a is attached.
to it; n is a plate fixed on central pin f, against which the spring o
presses; p is a conical bolt with engaging surfaces corresponding to
those of k, and attached at bottom to a four-sided pin ", which can
slide up or down in a similarly shaped grooves, and attached at top to 3
the pin f.
"

page_text: the rod a can turn freely. By removing this pressure, when a has been
moved round to the extent desired, its motion will be arrested by the
action of the spring o upon the plate n, which forces the bolt p into
contact with the cup k so soon as the corresponding surfaces reach a
point where they can engage with each other. The number of such
points depends upon the number of engaging surfaces and the intervals
between them, which may be regulated by convenience. It should be
observed, however, that this number may be multiplied without mate-
rially affecting the strength of the cup or clutch, because in every case
all the parts are engaged at once. The arms of the jointed rod may be
curved if required, so as to clear any obstructing projection.
In conclusion, I say that I do not limit myself to the particular
combinations of belts or clutches herein described, which are intended
only to illustrate the nature of my Invention, the same being susceptible
of application in different ways according to circumstances.
In witness whereof, I, the said Edward Vansittart Neale, have
hereunto set my hand and seal, this Twenty-ninth day of April,
in the year of our Lord One thousand cight hundred and seventy-
two.
EDWARD VANSITTART NEALE. (L.s.)
