the Office of the Commissioners of Patents, with his Petition, on
the 4th August 1871.
I, EDWARD-VAN SITTART NEALE, of 12, Church Row, Hampstead, in
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
EXCLUSIVELY 80, TO BE ADAPTED TO DOORS AND FRENCH 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 corre-
sponding 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 extent of the
adjustment made the coarse threaded screw forces it longitudinally, and
brings the said finer nuts and stopping staples or blocks into contact,

page_text: 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 rod Z."
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
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 dis-
connected.
Thirdly. In constructing or fitting up doors, French windows, and
swinging or hinged erections or articles of various kinds with a toothed
rack or serrated closing bar, and with a corresponding toothed or serrated
stop or closing catch, to be used together for regulating or adjusting and
maintaining the door, window, 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 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 said bar being sometimes
jointed to fold upon itself or otherwise.
Subject to any modifications not departing from the nature of the
Invention, the following is an illustrative description of the manner in
which it 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 removeable 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 con-
tinuous 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 pro-
jections.
As respects the third improvement the closing bar may be made
with any convenient form of tooth or serration, but preferably when

page_text: made to fold so as that the teeth or serrations may fit each other. 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, &c. (or to second division of the window, &c. 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.
