Improvements in Poles or Masts.
We, FREDERICK BAUMGART NICHOLSON and EDWARD JENNINGS JENNINGS of 7
Westminster Chambers Victoria Street London S.W. Electrical Engineers do hereby
declare the nature of this invention to be as follows:
The object of this invention is to produce a pole or mast for carrying a lantern or
the like (illuminated by electricity or other means) or for supporting electric light
leads, telegraph wires or similar or equivalent wires or the like, which shall admit of
simple and easy erection combined with firmness and reliability.
[t
In carrying out our invention we use several sections of gas barrel or similar metal
tubing or rods of convenient lengths, in conjunction with cast or wrought iron plates
forming horizontal platforms or ties at intervals according to the length of gas barrel
or the like, cach platform varying in dimensions in such manner that a gradual slope
is given to the barrel or the like so that the base of the mast or polo has considerable
spread " but the top is much smaller. Now we make the joint or attachment between
two consecutive sections of barrel or the like as follows-putting on each a backnut
we join them together by a "union" or collar which union forms as it were a liner to
a circular opening in the platform and the backnuts before mentioned being screwed
towards each other cause the platform to be tightly embraced, one backnut being of
course above and the other beneath the platform..
Now this platform may be triangular, square, hexagonal or of such other shape as
may produce a number of angles corresponding to the number of barrels or the like.
of which each section is composed, and the number of platforms will depend upon the
height which the pole or mast is to be, each one being sinaller than that underneath it
as before explained.
Lugs are formed on the platforms to admit of the connection of diagonal tie rods
between any two platforms the whole when braced together thus forming a rigid and
reliable pole. The base plate will be somewhat similar to a platform but will have
accomodation for "holding down bolts " to be attached to concreto blocks or other
anchorage.
. It is evident that the backnuts may be replaced by "jib and cottar" attachment
without affecting the general arrangement.

COMPLETE SPECIFICATION.
Improvements in Poles or Masts.
We, FREDERICK BAUMGART NICHOLSON and EDWARD JENNINGS JENNINGS of 7
Westminster Chambers Victoria Street London S.W. Electrical Engineers 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 :-
. The object of this invention is to produce a pole or mast for carrying a lantern or
the like (illuminated by electricity or the like means) or for supporting electric light
leads telegraph wires and similar or equivalent wires or the like which shall admit of
simple and easy erection combined with firmness and reliability.
The better to explain our meaning reference is made to the hereunto appended sheet
of Drawings in which Fig. 1 illustrates diagramatically one of the applications of our

invention A. A. being the said masts or posts and B. B the wires either electric
current such as telephone telegraph electric light wires or the like or also com-
bining weight carrying in conjunction with electrical propulsion such as telpher
lines in which case some of the "hays" between two posts may have to be rigid as
shown at should this be a curved part of the line." In Fig. 2 is shown A. a post
or mast having a wire B running across a stream and carrying attached thereto
electrical cables or other erection requiring support. In Fig. 3 is shown the pole
or mast overhanging a quay or dock in the form of a crane for illuminating
work beneath and Fig. 4. shows the pole acting as "sheer legs" for dockyard work
having a lantern at the top for night work or the like. It is obvious without
the necessity of further illustrations that this construction lends itself to various other
purposes in a most convenient manner amongst which may be named poles for
supporting overhead wires used in electric-traction.
In carrying out our invention we use several sections of gas barrel or similar metal
tubing or rods of convenient lengths in conjunction with cast or wrought iron
plates forming horizontal platforms or ties at intervals according to the length of
gas barrel or the like employed each platform varying in dimensions in such
manner that a gradual slope is given to the barrel or the like so that the base of
the mast or pole has considerable spread" but the top is much smaller. This will
be readily understood by reference to the drawings where Fig. 5 shows the general
elevation of one side of a pole or mast A being the barrel or the like, B, diagonal
tie C, C, platforms with lugs (to take the ties) D, also backnuts E. The plan of a
platform is shown and lugs marked D (in Fig. 6) as used on a triangular pole.
Now we make the joint or attachment between two consecutive sections of barrel
or the like as follows (see Fig. 7). Putting on each a backnut E, we join the tubes
bars or the like A by an ordinary "union
or collar F which union forms as it were
a liner to a circular opening in the platform C, and the backnuts beforementioned
-being screwed towards each other cause the platform to be tightly embraced, one
backnut being of course above and the other beneath the platform.
Now this platform may be triangular, square, hexagonal or of such other shape as
may produce a number of angles corresponding to the number of barrels or the like
of which each section is composed and the number of platforms will depend upon
the height which the pole or mast is intended to be each one being smaller than one
underneath as before explained.
.
Lugs are formed on the platform to admit of the connection of diagonal tie rods
between any two platforms the whole when braced together thus forming a rigid and
reliable pole. The base plate will be somewhat similar to the platform but will have
accommodation for "holding down bolts" to be attached to a concrete block or other
anchorage.
Fig. 8 shows two wrought iron discs G held between the locknuts and joined
together by channel iron H rivetted thereto. Backnuts are marked E and barrels A,
union F:
It is evident that the backnuts or locknuts may be for convenience replaced by gib
and cottar attachment without affecting the general arrangement. We do not neces-
sarily confine ourselves to the exact materials herein mentioned obviously steel and
other materials might be equally well employed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :.
First. The construction or arrangement and combination of the parts of a mast or
pole or its equivalent substantially as and for the advantages herein described in
reference to and shown in the accompanying drawings.
Second. The constructing of a mast or pole in sections composed of gas barrel
iron rods or other convenient materials in combination with horizontal platforms
substantially as and for the advantages herein described in reference to and shown in
the accompanying drawings.

page_text: Third. The combination of a platform of suitable materials, with a series of tubes
rods or the like of convenient materials and approximately of equal length in each
series joined by "unions" and backnuts or gib and cottar or other equivalent
fastening devices and fitted with diagonal stays substantially as and for the advantages
herein described in reference to and shown in the accompanying drawings.
Fourth. The combination of a jib or "sheer leg" constructed in accordance with
this invention and stays frames and other appurtenances to enable the same to be
safely and conveniently used at quays dockyards or the like for lighting the work
and if necessary carrying or raising goods substantially as and for the advantages
herein described in reference to and shown in the accompanying drawings.
