Improvements in or Connected with Stops for Double Gates
or the like.
I MILES POSTLETHWAITE of The Hollins Whitehaven in the County of Cumberland
Esquire do hereby declare the nature of this Invention to be as follows:-
My Invention relates to stops used to prevent double gates or the like swinging
beyond their closed position and has for its object to provide means whereby the
said stops are automatically raised when the gate is closed and lowered when the gate
is opened so as to constitute no obstruction in the roadway past the gate. I employ
a stop arranged so that when the gate is opened the said stop falls or enters into a
recess or casing situated at the part of the roadway whereat the portions of the gate
meet when the gato is closed. In connection with the said stop is an attachment
which is acted upon by or through the gate as it is closed so that the stop is raised into
position for the parts of the gate to abut against or each part of the gate may have an
independent stop whilst not necessarily limiting myself to precise details the arrange-
ment which I prefer is to provide for each part of the gate and extending under the
roadway parallel with the gate when it is closed a rod or shaft capable of partial
rotation in suitable bearings and carrying at one end a lever which is acted upon by
the gate or a projection thereon as it is closed so that the said rod or shaft is partly
rotated and another lever thereon raises the stop. When the gate is opened the stop
descends and in so doing the rod or shaft is acted upon thereby so as to bring its levers
into position for again being acted upon to raise the stop when the gate is closed.

Esquire 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 stops used to prevent double gates (or the like) swinging
beyond their closed position and has for its object to provide simple and efficient
means whereby the said stops are automatically raised when the Gate or the like is
closed and lowered when the gate is opened so as to constitute no obstruction in the
roadway past the gate. According to my Invention I employ a stop capable of
turning upon a centre so that when the gate is opened the said stop falls by gravity
from a vertical-to-a-horizontal-position and is received in a recess or casing situated
at the part of the roadway whereat the portions of the gate meet when the gate is
closed. Beneath the said stop is a lever attached to a shaft or rod situated in a
casing beneath the ground level and extending in a line parallel with the gate when
closed. On the other end of the said shaft or rod is another lever or arm which
projects above the roadway near to the hinge of the Gate so that as the Gate is being
closed it comes into contact with this arm and by partly rotating the rod or shaft the
lever at its opposite end bears on the stop so as to raise it into position for the gate to
come into contact with it. When the gate is opened the stop falls as described and
in so doing the rod or shaft is acted upon thereby so as to bring its levers into
position for again being acted upon to raise the stop when the Gate is closed.
There may be one stop for both the sides of the Gate the said stop extending across
the place where the parts of the gate meet when closed on either side a sufficient
distance for both parts of the gate to come into contact therewith or the said stop may
be arranged in such a position that only the part of the Gate which is first closed
comes in contact with it but I prefer to have two stops one for each part of the gate
and an arrangement such as I have described for raising it so that whichever of the
parts of the gate is closed whether purposely or by accident (by the wind for instance)
a stop rises to prevent its being swung beyond its proper closed position.
I will describe an arrangement according to this last plan with reference to the
accompanying drawing from which its general application will be well understood.
Figure 1 is a front elevation with the gates closed. Figure 2 is a front elevation
with the gates open and Figure 3 is a plan thereof. Figure 4 is a longitudinal
section. Figure 5 a transverse section on the line 1. 2. Figure 4 and Figure 6 is a
transverse section on the line 3-4. Figure 4 shewing the position of the parts when
the gate is closed and Figures 7, 8 and 9.

Figures 4 to 9 are drawn to a larger
are drawn and shew the arrangement

page_text: for one side of the gate only that for the other side being arranged in a similar
manner.
In the roadway parallel with the gates when closed are casings A with covers A²
level with the roadway. In each of the end parts A³ of the casing are stops B,
turning upon a centre at band having parts at B2 at right angles so that when the
stops B are raised the parts B2 fill the opening in the casing in which the stops B lie
when the gate is open. In each of the casings A is mounted a rod or shaft C capable
of partial rotation and having fixed thereto at each end a lever or arm. That at D
acts upon the stop B to raise it whilst that at E is acted upon by the part of the gate
at the hinge end to partially rotate the rod or shaft and so raise the lever D and
stop B. The arm E is preferably provided with an antifriction roller e and the gates
if of wood may have metal plates fixed thereto to bear on the rollers e and against the
stops B.
When either flap of the gate is closed its hinge end bears on the arm E
and by partly rotating the shaft C raises the lever 1 which in turn elevates the stop
sufficiently for the gate to come into contact with it. The Gate will then by bearing
on the stop completely raise it to its vertical position. The bolt or bolts for fastening
the gates may enter a hole at a made in the casing for its reception. The covers A²
form a convenient means for keeping the pins and shafts in place end wise by bearing
on the ends of the pins and upon the arms E. The two parts A of the casings may
be connected together by means of bolts passing through lugs formed thereon. The
covers A2 and stops B are capable of being readily removed for the purpose of
cleaning out any dust or dirt that may accumulate in the casings A.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is,
A gate stop consisting of a hinged flap or stop piece B acted upon by a lever or
projection on a shaft extending parallel with the Gate when closed to or near the
hinge end thereof where it is provided with another lever or arm acted upon by the
gate when being closed substantially as and for the purpose described.
