PROVISIONAL SPECIFICATION left by the said Edward Vansittart
Neale at the Office of the Commissioners of Patents, with his
Petition, on the 4th October 1871.
I, EDWARD VANSITTART NEALE, of 12, Church Row, Hampstead, in
5 the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS OR APPLIANCES FOR STOPPING
AND REGULATING THE EXTENT OF ANGULAR MOTION, AND INTENDED, THOUGH NOT

page_text: EXCLUSIVELY SO, TO BE ADAPTED TO DOORS AND FRENCH AND OTHER WINDOWS,"
to be as follows:-
The Invention consists, firstly, in constructing or fitting up a rod
or bar with a coarse or quick threaded male screw turning in a
corresponding concave screw or nut, and with one or more finer or.
slower threaded screw or screws, and one or more corresponding
adjusting or regulating concave screws or nuts to turn thereon or round
the same, and with one or more stopping staples or blocks through
which the rod passes or which are carried upon it, and against which the
finer nut or nuts may jam up, when by the turning of the rod to the 1
extent of the adjustment made the coarse-threaded screw forces it longi-
tudinally, and brings the said finer nuts and stopping staples or blocks
into contact, and arrests the angular or axial motion of the rod. The
combination of parts as thus firstly set forth is herein-after termed the
"improved stop-regulating rod," and the rod or bar portion thereof "the 1
rod Z."
2
Secondly. In constructing or fitting up doors, French windows, and
swinging or hinged erections or articles of various kinds with the
"improved stop regulating rod" firstly above set forth, by means of a
jointed arm to connect them together, "the rod.Z" and the pin or axis 2
of the jointed arm being parallel to the hinge, and the jointed arm
being sometimes made so as to fold upon itself or otherwise when
disconnected.
Thirdly. In constructing or fitting up doors, French windows, and
swinging or hinged erections or articles of various kinds with a regu- ?
lating compound adjustable expanding and collapsing bar for maintaining
them open or partly open, consisting of and being an arrangement of
levers crossing each other, with a pinching screw or stiffening equivalent
applied to one or more of the fulcra or joints to adjust, set, or govern the
length of the compound bar.
g
And, lastly. In constructing or fitting up doors, French windows, and
swinging or hinged erections or articles of various kinds with a toothed
rack, or serrated or embossed closing bar, and with a corresponding
toothed, or serrated, or embossed stop or closing catch, to be used
together for regulating or adjusting and maintaining the door, window, 3
erection or article at any desired angle or extent of opening, according
to the part of the length of the closing bar which is made to engage

page_text: with the closing catch, the said closing bar and closing catch, one or both,
being sometimes hinged or jointed to accomodate the angle of opening,
and the serrations or embossments being either on the bar or on
the stop.
The following is an illustrative description of the manner in which the
Invention is to be performed: "The rod Z" is to have the coarse and
fine screws
formed upon it or affixed to it permanently or in a remove.
able manner. The nut of the coarse screw and the stopping staples or
blocks will form bearings for the rod. The finer nuts serve to regulate
the extent of angular or axial motion of "the rod Z." The application
of the coarse screw by square fitting at end of rod will when the screw
is removed admit of continuous instead of oscillating motion of the rod.
As respects the second improvement, "the rod Z" is to be placed
so that the jointed bar may conveniently connect the door, window,
erection, or article, with its frame or some adjoining fixed object, and if
required, is to be curved to pass or work round obstructing projections.
·
As respects the third improvement, the compound expanding and
collapsing bar is intended to be constructed after the fashion of what is
sometimes called a "lazy-tongs" arrangement of levers, having spaces
or reticulations between the cross levers of a diamond or rhomboidal
form.
As respects the last improvement, the closing bar is to be made
with any convenient form of tooth, or serration, or embossing, and in
some cases to fold so that one part. may lie upon or along one side of
another, and in some cases telescopic, or with one part to slide within
another. The said closing bar and piece may be respectively attached
either to the window, etc., or to its frame as may be most convenient, or
if the window, etc., is double may be attached the one to the one division
and the other to the other division of it on the inner side and near to the
edge furthest from the hinge. And the said closing piece is to be
attached to the frame of the window, etc., (or to second division of
the window, etc., if double). The improved apparatus is to be used
either independently of the means employed to fasten the window, etc.,.
when shut, or as an espagnolette for the purpose, or the closing bar may
be attached to the back or bottom of an espagnolette.
The several improvements are to be employed in any convenient

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Vansittart Neale in the Great Seal Patent
Office on the 4th April 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
VANSETTART NEALE, of 12, Ohurch Row, Hampstead, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of October, 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 "IMPROVEMENTS IN APPARATUS OR APPLIANCES FOR STOPPING
AND REGULATING THE EXTENT OF ANGULAR MOTION, AND INTENDED, THOUGH NOT
EXCLUSIVELY SO, TO BE ADAPTED TO DOORS AND FRENCH AND OTHER WINDOWS,”
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 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 Edward Vansittart Neale, do
hereby declare the nature of my said Invention, and in what manner a
the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The Invention consists, firstly, in the constructing or fitting up a rod
or bar with a coarse or quick threaded male screw turning in a corre-
sponding concave screw or nut, and with one or more finer or slower

page_text: threaded screw or screws and one or more corresponding, adjusting, or
regulating concave screws or nuts to turn thereon or round the same,
and with one or more stopping staples or blocks, through which the rod
passes or which are carried upon it, and against which the finer nut or
nuts may jam up, when by the turning of the rod to the extent of the
adjustment made, the coarse threaded screw forces it longitudinally, and
brings the said finer nuts and stopping staples or blocks in contact, and
so arrests the angular or axial motion of the rod.
Secondly. In constructing or fitting up doors, French windows, and
swinging or hinged erections, or articles of various kinds with such a
rod as is above set forth by means of a jointed arm to connect them
together, the rod and pin or axis of the jointed arm being parallel
to the hinge, and the jointed arm being sometimes made so as to
fold upon itself or otherwise when disconnected. Figures 1 to 8
(Sheet 1) are Drawings shewing such an apparatus applied to fasten
a French window or door. Z is the rotating rod; a is the coarse
threaded male screw thereon; b is a staple containing the corresponding
concave screw connected with the plate f, which is attached to the frame
or wall at the side of the door or window; c is the finer or slower
threaded screw; d are two nuts turning thereon; e is a staple attached
to the plate f, through which Z passes, and against which the nuts d'aro
pressed by the rotation of Z, if screwed down so as to be close to e on
either side; is the jointed arm by which Z is connected with the door
or window; ³ is a joint by which the second arm may be lengthened or
shortened by folding back on itself so as to be fixed to the window or
door either at the joints ³ or h*. K is a joint at the bottom of Z, by
which the jointed rod when not in use may be folded against the rod Z.
Figure 7 exhibits a modification of the apparatus, where the nuts d, d,
screw in opposite directions through the staples e, e, and by pressing
against a projection Z* upon Z placed between them, arrest its rotary
motion. If this motion is required to be arrested in one direction only,
as in the case of a door provided with hinges, by which it is always
pressed in one direction, the nut which would arrest its rotation in the
opposite direction may be dispensed with. Also, the arms h may be
curved so as to pass round the frame of a door if the rod is fixed against
the wall beyond the frame. Further, in the case of doors, the rod Z
may be conveniently reduced to the length necessary for the action of

page_text: the coarse screw and nut, and the jointed arms when not. used may hang
beneath it, being lifted up and attached to the door at any convenient
height by means of a hook or eye when in use.
;
Figures 9, 9ª, 9³, and 9° (Sheet 2), shew such an apparatus, and are
respectively side view, elevation, section of staple shewing coarse threaded 5
screw and plan of staple. Z is the rotating rod; a is staple containing
a concave screw, in which the coarse threaded screw works; 6 is a nut
working on a fine threaded screw; c is the hinge or jointed arm; d, ď³,
are arms curved so as to pass round the jamb of the door; e is the joint
of the arms d, d'; f is a plate to which a is attached. The rod is to 1
be connected to the door by means of a pin attached thereto, made so as
to fold when not in use.
This principle may be applied to other cases when it is desired to
minutely arrest the angular motion, as for instance in the case of folding.
chairs, bed rests, etc. It may be also applied to secure the folding heads 1
of carriages, as a convenient substitute for the heavy arms at present
in use.
If it is desired to combine the mode of arresting angular motion above
described with the possibility of continuous circular movement, this may
be effected by connecting the coarse threaded screw with the part of the 2
rod containing the fine threaded screw by a joint admitting of being
disconnected at pleasure by any of the known methods applicable for
such a purpose.
:
Thirdly. My Invention consists in constructing or fitting up French
windows, and swinging or hinged erections, or articles of various kinds, 2
with a regulating compound adjustable expanding and collapsing bar
for maintaining them open or partly open, consisting of and being an
arrangement of levers crossing each other with a pinching screw or
stiffening equivalent applied to one or more of the fulcra or joints to
adjust, set, or govern the length of the compound bar. But inasmuch 3
as I have found the other applications of my Invention herein-after
described to be more convenient, I do not think it necessary to illustrate
this part of the Invention by any Drawings.
The fourth part of my Invention consists in constructing or fitting up
doors French windows or swinging or hinceed erectiona O articles of 3

page_text: various kinds with a toothed rack, or serrated or embossed stop or
closing catch, to be used together for regulating or adjusting and main-
taining the doors, window. erections, or articles at any desired angle or
extent of opening, according to the length of the closing bar, which is
5 made to engage with the closing catch, the said closing bar and closing
catch, one or both, being sometimes hinged or jointed to accomodate
the angle of opening, and the serrations or embossments being either
on the stops or on the bar, which may be made with any convenient
form, and in some cases to fold so that one part may lie upon or
O alongside of another, and in some cases telescopic, or with one part to
slide within another; and the said closing bar and piece being respec-
tively attached either to the window, etc., or to its frame, as may be
most convenient, or if the window, etc., is double, and the closing bar is
intended to act on both divisions at the same time, the one to the one
5 division and the other to the other division of it on the inner side and
near to the edge furthest from the hinge, and the said apparatus being
used either independantly of the means employed to fasten the window,
etc., when shut, or as part of such means.
This part of my Invention admits of various modes of application, of
O which four of the most convenient are shown in Figures 10 to 16.
Figures 10, 11, 12, (Sheet 3) show a closing bar attached to a window,
opening inwards; Figure 10 shews a closing bar and catch when the
window is closed, and Figures 11 and 12 when it is open. a is the
closing bar serrated on its back or inner surface; b, c, the two divisions
5 of the window; d is a plate to which a is hinged; e is a plate attached
to b, to which d is fixed by a hinge at right angles to the hinge of a, and
at the edge of b; f is a catch or box hinged on the edge of 6, with
serrations corresponding to those of a.
Figures 13, 14, 15, 16 (Sheet 4), shew a folding closing bar applied
to a window opening outwards, 13 being a plan when the window is
open, and 14 an elevation of the bar when the window is closed, and
15 and 16 enlargements of the box or catch. a, b, are the arms of the
closing part serrated on the side towards the window; c is a box con-
taining in its lower part serrations corresponding to those of a or b, and
5 turning upon a pivot in the plate h; d is a piece connected with a and
hinged to e; e is a plate fastened to f; f is the frame of the window ;

page_text: I
is the window sill; & is a plate annexed to g; ; is the pivot on which
c turns. It should be placed so as to allow of being turned round by the
bar when this is sufficiently raised to set the serrated part of it free from
the corresponding part of the turning box or catch.
Figures 17, 18, and 18 (Sheet 5) shew the telescopic closing bar; t
Figure 17 is a section of closing bar drawn out, and Figures 18 &
18ª sectional details of same. a is a tube forming the body of the
closing bar which is furnished with a slit; o is a nut surrounding the
tube, by means of which it can be compressed through the action of a
conical or tapering screw in the way commonly employed to arrest the 1
motion of a lathe; d is a sliding or telescopic piece which may be
either a tube or a rod having a hook e, by which it may be attached
to the division of the window opposite to that on which a is fixed; fis a
ring or other joining by which a is attached to the window so as to be
capable of taking different positions when the window is opened. Such 1
a closing bar is shewn applied as the ordinary fastening of a double
window, opening inwards, in Figures 19, 20, 21, and 22 (Sheet 5), of
which Figures 19 and 20 shew the window when closed, and 21 and 22
when open.
a is the closing bar; b, the telescopic piece; c, hook con-
nected with it; d split ring fixed on a, which can be compressed by 2
moving the handle e; f is a plate on which a is fastened by a pivot
passing through a piece attached to a at bottom, so that a can move in a
plane parallel to the window when this is shut; & is a hinge by which f
is fixed to a plate i, sliding between two bars j and k, fixed on the
window, which should be long enough to allow a to clear the edge of the 2
window when placed obliquely across it to the full extent of the opening
contemplated; m is a ring fastened either to the lower edge of the
opposito division of the window or to the side next the hinge, according
to the size of the window, at a point such that the hook c can be
inserted into it when the window is shut and is drawn out to its full 3
extent. If this hook is attached to the side of the window it must be
pivoted so as to be able to adapt itself to the different positions taken
by a when the window is opened, as is indicated by the inclination given
it in the Figures. n is a second hook fixed on the lower edge of the
window, near to the centre, so as not to interfere with the motion of i; 3
o is the catch into which e is placed to fasten the window when shut.
To use this apparatus, it is necessary only to insert c into m, drawing

page_text: out i, and then to pull the window open. The closing bar will elongate
and adjust itself to the required angle and can be fixed thus by turning
round the handle as indicated by the arrow, Figure 19. If it is desired
to open the window to an extent greater than can be reached by the
3 closing bar when placed obliquely across it, the hook c must be removed
from m and placed in n. By this means the first division of the window
may be fixed open to any extent, from the smallest possible to the full
length of the closing bar, when placed horizontally across it. In order
to apply the same operation to the second division of the window, which
may be done by reversing the position of the closing bar, two other
rings p, p³, are necessary, placed on the back or outside of this division,
as shewn, of which p should be hinged to the window, and should be
large enough to allow of the hook c adapting itself to the different
positions taken by the closing bar when placed obliquely across the
window; p¹ and n are ordinary fixed rings which may hang down or
not as preferred. As the fastenings of French windows are commonly
fixed thirty inches above the bottom of the window, such a closing bar
would allow both divisions of a window four feet ten inches broad to be
fixed onan at right angles.

page_text: be fixed open at various degrees of opening. By fixing i upon a sliding
piece which will draw out so as to clear the rabbit as described in
Figure 19, the use of ; may be dispensed with. None of these rings
require to hinge, which is needed only where the closing bar when
employed is not horizontal, or for the purpose after mentioned.
may
open
By employing two telescopic closing bars, each of a length when
closed equal to one-half of one division of a double window attached as
last described, opposite to each other, of which the one carries a hook
be fixed
and the other a corresponding ring, the window
to any
extent, from the least possible degree to a right angle. The liability to 1
lateral motion from the closing bars assuming different positions without
any alteration in their length may be prevented by furnishing the hook
and ring with sides, which may be conveniently six in number.
Figure 24 shews the plan of such a ring and hook where a is the ring.
shewn attached to a rod, b. the hook, and can eccentric plate fixed on 1
top of b, by turning which over the side of the ring the hook may be
prevented from falling out.
In like manner by the use of a many sided hook and corresponding
rings hinged to the window so as to be capable of adapting themselves to
the different angles taken by the closing bar, a double window fastened 2
by a single telescopic bar may be fixed open so as to prevent any lateral
motion, although neither division should be otherwise fastened.
A telescopic closing bar 'may be inserted into or otherwise combined
with the vertical fastening of an espagnolette by the application of
mechanical arrangements, which I do not describe more fully because 2
they do not involve the application of any other contrivances than such
as are either well known or sufficiently described above. Also the
above-mentioned methods of fixing French windows partially open may
be applied as part of the handle or bar used to close the window in
espagnolette fastenings, but I do not describe any of such applications a
because I have found them less convenient than those herein specified.
The different apparatus and fastenings above described may be of any
convenient size and strength in accordance with the windows or doors to
which they are applied, but they must necessarily vary in accordance
therewith.

page_text: In conclusion, I say that I do not limit myself to the particular
modes of effecting the different purposes of my Invention herein-before
set forth, but state them only as convenient methods of so doing, claiming
the right of using any other combinations or of applying my said
Invention to any other purpose falling within the general description
above given which may be found advantageous.
In witness whereof, I, the said Edward Vansittart Neale, have
hereunto set my hand and seal, this Fourth day of April, in the
year of our Lord One thousand eight hundred and seventy-two.
