page_text: LETTERS PATENT to Richard Brotherton, of Wolverhampton, in the
County of Stafford, Wrought-iron Tube Maker, and Joseph Waldron, of
Wolverhampton, aforesaid, Wrought-iron Tube Maker, for the Invention
of
IMPROVEMENTS IN THE MANUFACTURE OF LAMP POSTS."
Sealed the 20th December 1867, and dated the 10th October 1867.
PROVISIONAL SPECIFICATION left by the said Richard Brotherton and
Joseph Waldron at the Office of the Commissioners of Patents, with
their Petition, on the 10th October 1867.
We, RICHARD BROTHERTON, of Wolverhampton, in the County of Stafford,
Wrought-iron Tube Maker, and JOSEPH WALDRON, of Wolverhampton,
aforesaid, Wrought-iron Tube Maker, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF LAMP POSTS," to be
as follows:-
Our Invention consists in making lamp posts of wrought iron or partly of
wrought iron and partly of cast iron, substantially in the manner herein-after
explained, by which method of manufacture lamp posts are produced lighter,
stronger, and cheaper than ordinary lamp posts, and free from the liability to
fracture common to ordinary lamp posts.
In making lamp posts according to our Invention we employ tubing of
wrought iron, either of a cylindrical figure or of a taper figure. When we
employ taper tubing we make a portion of the tube at its widest end cylin-
८

page_text: drical for the purpose of forming the screw, herein-after described, upon it.
We cut a screw on the top and outside of the tube, and we fix the lamp iron
for the reception of the lamp on the said screwed top of the tube. The cross
bar we make of two pieces of tubing screwed at opposite points, and at the
required height into the principal tube or post. The skeleton frame of the
Jamp post or the part buried in the earth we make either of wrought iron or of
cast iron. When we make it of wrought iron we fix the base of the principal
tube or post therein by screwing. When we make the said frame of cast
iron, we prefer to fix the principal (tube therein by casting the said frame on
the end of the said tube; or the principal tube may in this case be fixed in
the said frame by screwing.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Brotherton and Joseph Waldron in the Great Seal
Patent Office on the 4th April 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, RICHARD
BROTHERTON, of Wolverhampton, in the County of Stafford, Wrought-iron
Tube Maker, and JOSEPH WALDRON, of Wolverhampton, aforesaid, Wrought-
iron Tube Maker, send greeting.

Islands, and Isle of Man, an Invention for "IMPROVEMENTS. IN THE MANU-
FACTURE OF LAMP POSTS," upon the condition (amongst others) that we, the
said Richard Brotherton and Joseph Waldron, our executors or adminis-
trators, by an instrument in writing under our or their hands and seals,
or under the hand and seal of one of us or them, should particularly describe
and ascertain the nature of the said. Invention, and in what manner the
same was to be performed, and cause the same.to. be filed in the Great

page_text: Seal Patent Office, within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that we, the said Richard Brotherton and Joseph.
Waldron, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and.
ascertained in and by the following statement thereof, that is to say :-
Our Invention consists in making lamp posts of wrought iron or partly of
wrought iron and partly of cast iron, substantially in the manner herein-after
explained, by which method of manufacture lamp posts are produced lighter
and stronger than ordinary lamp posts, and free from the liability to fracture
common to ordinary lamp posts.
In making lamp posts according to our Invention we employ tubing of
wrought iron either of a cylindrical figure or of a taper figure. When wo
employ taper tubing we make a portion of the tube at its widest end cylin-
drical for the purpose of forming the screw berein-after described upon it.
We cut a screw on the top and outside of the tube, and we fix the lamp iron
for the reception of the lamp on the said screwed top of the tube. The cross
bar we make of two pieces of tubing screwed at opposite points and at the
required height into the principal tube or post. The skeleton frame of the
lamp post, or the part buried in the earth, we make either of wrought iron or
of cast iron. When we make the said frame of wrought iron we fix the base
of the principal tube or post therein by screwing. When we make the said
frame of cast iron we prefer to fix the principal tube therein by casting the
said frame on the end of the said tube. Or the principal tube may in this
case be fixed in the said frame by screwing.
Having explained the nature of our Invention we will proceed to describe,
with reference to the accompanying Drawing, the manner in which the same
is to be performed.
lamp
Figure 1 represents in elevation, and Figure 2 in vertical section, a
post made according to our Invention; Figures 3, 4, 5, and 6, represent parts
of the same on a larger scale.
a is the lamp post made of a cylindrical tube of wrought iron; b is the base
or skeleton frame of the post made of cast iron, the said frame being buried
in the earth; c is the lamp iron for the reception of the lamp; d is the cross
bar of the lamp post. We make and attach the lamp iron c to the wrought
iron, post or tube a in the following manner:-The said lamp iron consists of
a frame of vertical bars c attached by rivetting to the square top ring e and
circular bottom ring f, as will be understood by an examination of the elevation
and plan Figure 3. A cross plate or bar 9 serves as a guide for the gas pipe.

page_text: The lower ring is screwed internally, and on the top and outside of the lamp
post a a screw a² is cut of a size proper to take into the hollow screw in the
ring f. By engaging the screw of the lamp iron with that on the top of the
lamp post, the said lamp iron is securely fixed to the said post, as illustrated
in the Drawing. The cross bar d of the lamp post (one half of which is
represented in elevation and section on a larger scale in Figure 4) consists of
two pieces of wrought-iron tubing d, d, having a screw d' on one end and closed
at the other end by a wrought-iron cap d³ welded thereto. At the required
height in the post a screwed holes at d³ are made in which the screwed ends
d' of the tubes d take, and the said tubes are thereby fixed to the post and
the cross bar formed as represented in Figures 1 and 2. We fix the lamp
post a to the cast-iron base or skeleton frame b in the following manner :-
The top of the skeleton frame b has a plain hole made in its axis, the said
hole having a diameter a little greater than that of the base of the lamp post.
On the bottom of the lamp post a screw a³ is cut. Before inserting the
screwed bottom of the post into the hole in the frame b a screwed collar or
washer h (shown on a larger scale in Figure 5) is screwed to the top of the
screw a³ on the post, and after the end of the post. has been introduced into
the frame as represented in Figures 1 and 2, the screw nut i (shown on a
larger scale in Figure 6) is screwed on the bottom of the post. The lamp
post is thereby fixed very securely to the skeleton frame b. Instead of fixing
the end or base of the tube or post in the cast-iron frame b by screwing as
described, the said end of the post may be fixed therein by casting the frame b
on the end of the post or tube a.
Figure 7 represents in plan, and Figure 8 in elevation, a skeleton frame for
the lamp post made of wrought iron, and Figure 9 represents a vertical
section of the same, to which a portion of a lamp post made according to our
Invention is fixed by screwing. The said skeleton frame is made of two
curved wrought-iron plates k, k, fixed by rivetting at top and bottom to the
angle bars l, m. To the top angle bar a circular plate n is rivetted, the
said plate having a hole in its axis of a size proper to receive the screwed
end as of the lamp post a. The lamp post a is fixed to the wrought-iron
frame by the screw collar h and nut i, as represented in Figure 9, and in the
manner previously described with respect to Figures 1 and 2.
Instead of making the post of the lamp of a cylindrical tube of wrought
iron as described and illustrated in the Drawing a wrought-iron tube of a
taper figure may be employed. In this case a portion of the tube at its
widest end is made cylindrical for the purpose of forming the screw for fixing
it to the base or skeleton frame of the lamp post..

page_text: Having now described the nature of our Invention, and the manner in
which the same is to be performed, we wish it to be understood that we do
not limit ourselves to the precise details herein described and illustrated, as
the same may be varied without departing from the nature of our Invention ;
but we claim as our Invention the improvements in the manufacture of
lamp posts, herein-before described and illustrated in the accompanying
Drawing, that is to say, making the principal post of the lamp and the cross
bar of the said post of wrought-iron tubing, and fixing the cross bar lamp
iron and cast-iron or wrought-iron skeleton frame to the said post, sub-
stantially as described and illustrated.
In witness whereof, we, the said Richard Brotherton and Joseph
Waldron, have hereunto set our hands and seals, this Thirty-first day
of March, in the year of our Lord One thousand eight hundred and
sixty-eight
