We, ROBERT RAMSAY MAIN, of Clydesdale Iron Works, Possilpark, in the
City of Glasgow, Engineer, and ROBERT RAMAGE, of 81 High Street, Langholm,
in the County of Dumfries, Plumber, do hereby declare the nature of this invention
to be as follows:-
-
This invention has for its object the provision of simple means for securing wires
to the standards and droppers of wire fencing and it is especially applicable in
securing barbed wire at the top of a fence in cases in which it is desirable to have
such wire occasionally removed and replaced.
The standard or dropper which may be of H, T, or other section is slit or has a
slot formed in the web at its upper end into which the wire is passed and at the
bottom of which it rests being there secured so that it may not rise out of the slot
by means of a locking piece pivoted on the web.
In one modification the locking piece is composed of a crescent shaped pin passed
through a circular orifice at or about the mid length of the slot the pin having a
cap or disc at either end and being adapted to rotate in the web. A slit is cut or
formed in the caps into which the fence wire entered by the upper open end of the
slit or slot in the standard is dropped whilst the slots are in line, so as to rest in
said slits and in the concave part of the pin. When the wire is so placed the pin is
turned round on its axis half a revolution whereby the wire is carried round and
allowed to drop into the lower end of the slot in the standard and is locked therein.
The wire may be freed by raising it into the concavity in the locking pin and
turning the latter round on its axis until the wire is brought from the under to the
upper side of the locking pin thereupon it is lifted out of the open end of the slot
in the standard.
Instead of being carried round by a crescent shaped pin the wire may be dropped
into a slit in a cap centred on the standard web, and carried thereby through a
portion of the slot in the standard which in lieu of being straight is made in the
form of an are whose centre coincides with that of the cap.
In lieu of the rotating locking pin or cap a slotted plate or plates pivoted on one
or both sides of the web may be used such plate or plates being swung up clear of
the slot in the standard when entering the wire thereinto and thereafter swung
down so that it or they engage with the wire and prevent it rising in the slot.

City of Glasgow, Engineer, and ROBERT RAMAGE, of 81 High Street, Langholm,
in the County of Dumfries, Plumber, 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:-
This invention has for its object the provision of simple means for securing wires
to the standards and droppers of wire fencing and it is especially applicable in
securing barbed wire at the top of a fence in cases in which it is desirable to have
such wire occasionally removed and replaced.
The standard or dropper which may be of H, T, or other section is slit or has a
slot formed in the web at its upper end into which the wire is passed and at the
bottom of which it rests being there secured so that it may not rise out of the slot
by means of a locking piece pivoted on the web.
The invention is illustrated under several modifications in plan and front elevation
respectively at Figures 1 and 2, 3 and 4, 5 and 6, and 7 and 8.
C
In the modification illustrated at Figures 1 and 2 the locking piece is composed
of a crescent shaped pin a passed through a circular orifice at or about the mid
length of the slot formed in the web of the standard or dropper d, the pin a having
a cap or disc e at either end and being adapted to rotate in the web. A slit is
cut or formed in the caps e into which the fence wire 9 entered by the upper open
end of the slit or slot c in the standard d is dropped whilst the slots are in line, so
as to rest in said slits and in the concave part of the pin a. When the wire g is
so placed the pin a is turned round on its axis half a revolution whereby the wire is
carried round and allowed to drop into the lower end of the slot c in the standard d
and is locked therein by further turning the pin a. The wire g may be freed by
raising it into the concavity in the locking pin a and turning the latter round on its
axis until the wire is brought from the under to the upper side of the locking pin,
thereupon it is lifted out of the open end of the slot c in the standard d.
As shown in Figures 3 and 4 instead of being carried round by a crescent shaped
pin the wire g may be dropped into a slit h in a cap i centred at j on the standard
web, and carried thereby through a portion of the slot c in the standard which in
lieu of being straight is made in the form of an arc whose centre coincides with that
of the cap.
In lieu of the rotating locking pin or cap a slotted plate or plates of the form
shown at Figures 5, 6, 7 and 8 pivoted at l on one or both sides of the web of the
standard d may be used such plate or plates k being swung up clear of the slot c in
the standard d when entering the wire g thereinto and thereafter swung down so
that it or they engage with the wire gaud prevent it rising in the slot c.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is :-
In wire fencing the combination with a standard or dropper of a locking pin or
plate constructed and arranged to operate substantially as described under several
modifications with reference to the annexed drawings.
