page_text: LETTERS PATENT to Samuel Roberts, of the Firm of John and
Samuel Roberts, of West Bromwich, in the County of Stafford,
Ironfounders, for the Invention of: "IMPROVEMENTS IN APPARATUS TO
BE USED IN THE MANUFACTURE OF CAST FLANGED PIPES, COLUMNS, TELEGRAPH
POSTS, LAMP PILLARS, AND OTHER CAST, HOLLOW, AND SOLID FLANGED
ARTICLES."
Sealed the 30th May 1876, and dated the 9th December 1875.
PROVISIONAL SPECIFICATION left by the said Samuel Roberts at the
Office of the Commissioners of Patents, with his Petition, on the
9th December 1875.
I, SAMUEL ROBERTS, of the Firm of John and Samuel Roberts, of
West Bromwich, in the County of Stafford, Ironfounders, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN APPARATUS
TO BE USED IN THE MANUFACTURE OF CAST FLANGED PIPES, COLUMNS, TELEGRAPE
POSTS, LAMP PILLARS, AND OTHER CAST, HOLLOW, AND SOLID FLANGED ARTICLES,"
to be as follows:-
My Invention has reference to those parts of the apparatus used in

page_text: the manufacture of cast flanged pipes, columns, telegraph posts, lamp
pillars, and other cast, hollow, and solid flanged articles which have for
their object the formation of the flanges of the articles enumerated and
other cast articles, and my said Invention consists in constructing and
arranging the parts of the said apparatus in the manner herein-after
described.
I will describe my Invention as applied to the casting of a flanged
pipe.
. I form by preference by casting annular hollow collars or rings having
the diameter of the flanges to be cast on the pipe, and I fit upon and
fasten the said collars or rings at the required positions on the ordinary
wrought or cast-iron core bar by means of set screws. The annular
collars or rings described have a cupped or trough form, and in the
bottom or base of the said collars or rings a series of equidistant holes
parallel with the axis of the collar is made, the number of holes in the
said collars corresponding with the number of holes required in the
flanges of the cast pipe. Through these holes in the collars or rings
´cores are inserted which, when the collars or rings are fitted in their
places on the core bar, project into those parts of the mould in which
the flanges of the pipe are cast.
Before the core bar with a collar or ring fixed upon each end of it is
placed in the mould box the said core bar is covered with hay and
afterwards with loam in the usual way, and at the same time and with
the same loam box a coating of loam is covered over or
"stuck" upon
the inner faces of the annular collars or rings.
Instead of using with the apparatus described a pattern of the
ordinary kind for forming the mould I use with the said apparatus a
pattern having upon each end, a broad collar or "print." When the
mould is made by the use of this pattern a cylindrical space is left at
each end of the mould of a size proper to receive the collars or rings on
the core bar, and also to form those parts of the mould in which the
flanges of the pipe are cast.
:.
The half moulds, having been formed by the use of the pattern
described the prepared core bar is introduced, into one of the said half
moulds in such a position that the loamed or coated faces.of the collars
or rings on the core bar are at the required distances from those parts of
"

page_text: the mould formed in the sand by the "prints" or collar parts of the
pattern, the cores in the said collars or rings on the core bar projecting
into those parts of the mould in which the flanges of the pipe are to be
cast.
The second half mould box having been fitted in its place, and the
two half mould boxes fixed together in the usual way, the mould is
ready for casting the pipe.
Instead of preparing the faces of the annular collars or rings with
loam when fixed on the corc bar as described the said collars or rings
may be detached from the core bar and their faces coated with loam and
dried in a stove. The prepared collars are then slipped on and fixed to
the core bar and the combined core bar and collars or rings inserted in
the mould. And instead of fixing the collars on the core bar before
introducing the latter into the mould, one or both of the said collars
may be inserted from the end or ends of the mould after the core bar
has been put in its place.
In manufacturing cast flanged columns, telegraph posts, and other
cast, hollow, and solid flanged articles I proceed in the manner described
with respect to a flanged pipe.·
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Roberts in the Great Seal Patent Office on
the 1st June 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
ROBERTS, of the Firm of John and Samuel Roberts, of West Bromwich,
in the County of Stafford, Ironfounders, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of December, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs, and successors, give
and grant unto me, the said Samuel Roberts, Her special license that I,
the said Samuel Roberts; my executors, administrators, and assigns, or
such others as I, the said Samuel Roberts, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to

on the core bar c is at the required distance from the cylindrical space
formed in the sand by the " print" or part 9 of the pattern p, as
illustrated in Figure 1, where the space left between the loamed face of
the collar or ring a and the print or impression in the sand in which the
flange of the pipe is to be cast is marked k. The cores e, e, are next
inserted from the trough sides of the collars or rings a, a, through the
holes ff, in the said collars or rings to form the holes in the flanges of
the pipe, the said cores e, e, projecting into the spaces k in the mould in
which the flanges of the pipe are cast, as seen in Figure 1. The second
half mould box being fitted in its place on the first half mould 'box and
fixed in the usual way the mould x is ready for casting the pipe.
By an examination of Figure 1 the relative positions of the several
parts when the mould is ready for casting a flanged pipe will be readily
seen.
Instead of preparing the faces of the annular collars or rings a, a, of
the core bar with loam when fixed on the said core bar as described, tho
said collars or rings a, a, may be detached from the core bar and their
faces coated with loam and dried in a stove. The prepared collars or
rings a, a, are then slipped on and fixed to the core bar, and the
combined core bar and collars or rings inserted in the mould. And
instead of fixing the collars a, a, on the core bar before introducing the
latter into the mould one or both of the said collars may be inserted
from the end or ends of the mould after the core bar has been put in its
place.
In manufacturing cast flanged columns, telegraph posts, and other
cast, hollow, and solid flanged articles, I proceed in the manner described
and illustrated with respect to a flanged pipe.
By manufacturing cast flanged pipes and other flanged articles by the
use of my Invention the flanges of the said pipes and articles are made
very perfect and true, and are at right angles to the axis of the pipe or
article; the holes in them are equidistant, and in consequence of the
metal being cast against the loam faced collars a, a, the flanges are
malleable and easily turned and faced instead of being hard and brittle,
as when made in the ordinary way.
Having now described the nature of my Invention, and the manner
in which the same is to be performed, I wish it to be understood that I
do not limit myself to the precise details herein described and illus-

page_text: trated, as the same may be varied without departing from the nature of
my Invention, but I claim as my Invention the improvements in
apparatus to be used in the manufacture of cast flanged pipes, columns,
telegraph posts, lamp pillars, and other cast, hollow, and solid flanged
articles herein-before described and illustrated in the accompanying
Drawing, that is to say, making those parts of the moulds in which the
flanges of the pipes and other flanged articles are cast by means of
annular collars; rings, or facing flanges fixed on the core bar, the said
collars, rings, or facing flanges having holes in them through which
cores to form the holes in the cast flanges are inserted, the combined
core bar and collars, rings, or facing flanges being constructed and used
substantially as described and illustrated, also making the pattern used
in forming the mould with broad "prints or "porty," pieces for
"
the purpose, and substantially as described and illustrated.
In witness whereof, I, the said Samuel Roberts, have hereunto:
set my hand and seal, this Twenty-ninth day of May, in the
year of our Lord One thousand eight hundred and seventy-
six.
Witness,
JOHN SMART,
West Bromwich.
