An Improvement in Swing Gates.
I, JAMES HENRY HANNAY, of Raleigh Club, Regent Street, in the County of
London, Gentleman, do hereby declare the nature of this invention to be as
follows:
-
My invention relates to a gate such as has the upper hinge situated out of
vertical line with the lower hinge, so that the gate automatically closes, and the
object of my invention is to provide simple means of opening such a gate in
either direction by a cord, chain, or other pull actuated at a distance from the
gate.
For this purpose I make the lower hinge work as a ball in a cup and I pivot the
upper hinge in a lever which is pivotted to the post, and from opposite arms of
which two cords, chains, or pulls lead to the distant place whence the gate is to
be operated. When neither of the pulls is acted on, the lever on which the
upper hinge is pivotted occupies a middle position, the gate being closed.
When either pull is operated, the lever is turned on its pivot bringing the upper
hinge to the one or the other side of its middle position and so causing the gate
to swing to that side.

An Improvement in Swing Gates.
I, JAMES HENRY HANNAY, of Raleigh Club, Regents Street, in the County of
London, Gentleman, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:
-
My invention relates to a gate such as has the upper hinge situated out of
vertical line with the lower hinge, so that the gate automatically closes, and the
object of my invention is to provide simple means of opening such a gate in
either direction by a cord, chain, or other pull actuated at a distance from the
gate.
For this purpose I arrange the gate so as to operate as I shall describe referring
to the accompanying drawings. Fig. 1 is a front view and Fig. 2 is a plan of the
gate in the closed position and Fig. 3 is a section of catch for holding the gate
open, I make the lower hinge a work as a ball in a cup and I pivot the upper

page_text: hinge in the arm 6 of a vertical rocking shaft c which is carried down the post and
has on it a pulley or sprocket wheel d, connected by a cord or chain e to a pulley
or sprocket wheel on a corresponding vertical rocking shaft f at the distant
place whence the gate is to operated. When the shaft c is in its middle position
the arm 6 on which the upper hinge is pivotted occupies a middle-position the
gate being closed. When the shaft f is turned by a handle h to the one side or
the other the arm 6 is moved bringing the upper hinge to the one or the other
side of its middle position and so causing the gate to swing to that side to a
position where it may be held by a catch k. On moving the handle h again
towards its middle position, the lower edge of the gate is first sufficiently raised
to clear the catch k so that it is free to swing to its middle position.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:-
A swing gate having its upper hinge pivotted in an arm projecting from a
vertical rocking shaft having on it a pulley or sprocket wheel connected by
cord or chain to a pulley or sprocket wheel on another vertical rocking shaft
provided with a suitable handle by which it can be turned, substantially as and
for the purpose set forth.
