PROVISIONAL SPECIFICATION left by the said Edwin Clark, at the Office
' of the Commissioners of Patents; with his Petition, on the 4th February
1856.
I, EDWIN CLARK, of 24, Great George Street, Westminster, do hereby
declare the nature of the Invention for "AN IMPROVEMENT IN THE APPARATUS
FOR SUSPENDING INSULATED ELECTRIC TELEGRAPH WIRES," to be as follows:-
This Invention has for its object an improvement in the apparatus for
suspending insulated electric telegraph wires. For which purpose, the arms
.and the caps, by which the suspension above the earth is accomplished, in place

suitable material, and the cap and arm is made with a gutter to carry off rain
from above the insulation which is suspended within the cap.

(amongst others) that I, the said Edwin Clark, 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 Inven-
tion, and in what manner the same was to be performed, and cause the same to

NOW KNOW YE, that I, the said Edwin Clark, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object an improvement in the apparatus for
suspending insulated electric telegraph wires. For which purpose, the armis
and the caps, by which the suspension above the earth is accomplished, in
place of being made separate in each case, are made of one piece of metal or
other suitable material, and the cap and arm is made with a gutter to carry off
rain from above the insulator, which is suspended within the cap.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.

page_text: DESCRIPTION OF THE DRAWING.
Figure 1 shews a plan and side view, partly in section, of one form of arms
and cap according to my Invention; Figure 2 shews a plan and side view,
partly in section, of another form of arm and cap according to my Invention;
and I would state that the forms of the arms and the caps may be varied so
long as an arm and cap is in one piece, as shown. a, a, are the metal arms,
terminating with inverted hollow metal caps of a suitable form for receiving
the earthenware or glass insulator for suspending the wires. I make the caps
with gutters around them, as shown. The arms and inverted hollow caps are
best made of one piece of cast iron, the wrought iron or other metal may
be used, and even earthenware might be employed.
In witness whereof, I, the said Edwin Clark, have hereunto set my hand
and seal, this Eighteenth day of July, in the year of our Lord One
thousand eight hundred and fifty-six.
Witness,
ROBERT JOHNSON.
EDWIN CLARK. (L.S.)
