IMPROVEMENTS IN THE MANUFACTURE OF TRAM-RAILS
Year: 1880

page_text: LETTERS PATENT to Josiah Smith, the younger, Edward Lones, and Joseph
Hill, all of Barrow in Furness, in the County of Lancaster, for an Invention
of "IMPROVEMENTS IN THE MANUFACTURE OF TRAM-RAILS."
PROVISIONAL SPECIFICATION left by the said Josiah Smith, Edward
Lones, and Joseph Hill at the Office of the Commissioners of Patents on the
4th September 1880.
JOSIAH SMITH, the younger, EDWARD LONES, and JOSEPH HILL, all of Barrow in
Furness, in the County of Lancaster. "IMPROVEMENTS IN THE MANUFACTURE
OF TRAM RAILS."
Our Invention relates to a method of manufacturing tram rails having a flanged
base and a head with a groove. We first roll the rail in a horizontal attitude' so as
to produce the flanges projecting on both sides of the base, and the head projecting
on each side of the middle rib, the head thus produced having as yet no groove in
it. We then pass the rail in an inclined attitude through a pair of rolls, one of
them so shaped as to bear on the underside of the flanged base, and on the under
side of one of the shoulders of the rail head, and the other so shaped as to bear on
the upper surface of one of the flanges, and on the rail head; the part which bears
on the rail head has a projecting collar which forms the groove in the head, but
wider at the mouth than required. The rail is finally passed again in a horizontal
attitude through a pair of rolls which finish the surface, pressing in the sides of the
rail head so as to bring it and its groove to the desired shape. Although we have
mentioned the several pairs of rolls employed as if they were separate, they may
obviously be different portions of a single pair of rolls, these portions having the
profiles required. Also, the rolls instead of being two high, may be three high,
as is well understood.

JOSIAH SMITH, the younger, EDWARD LONES, and Joseph Hill, all of Barrow
in Furness, in the County of Lancaster. "IMPROVEMENTS IN THE MANUFACTURE
OF TRAM RAILS."
Our Invention relates to a method of manufacturing tram rails having a flanged
base and a head with a groove. We first roll the rail in a horizontal attitude so as
to produce the flanges projecting on both sides of the base, and the head projecting
on each side of the middle rib, the head thus produced having as yet no groove in
it, as indicated at A. We then pass the rail in an inclined attitude through a pair
of rolls, one of them so shaped as to bear on the underside of the flanged base, and
on the underside of one of the shoulders of the rail head, and the other so shaped.
as to bear on the upper surface of one of the flanges and on the rail head. The
part which bears on the rail head has a projecting collar a, which forms a groove
in the head, but wider at the mouth than required. This rolling operation is
indicated at B. The rail is finally passed again in a horizontal attitude through a
pair of rolls which finish the surface, pressing in the sides of the rail head, so as to
bring it and its groove to the desired shape, as indicated at C. The several pairs of
rolls employed in the manner described may be separate, or they may be different
portions of a single pair of rolls as shewn, these portions having the profiles
required. Also, the rolls instead of being two high, may be three high, as is well
understood.
Having thus described the nature of our Invention, and in what manner the
same is to be performed, we claim,-
The herein described method of manufacturing grooved tram rails.
In witness whereof, I, the said Edward Lones, have hereunto set my hand
and seal, this Nineteenth day of February, in the year of our Lord One
thousand eight hundred and eighty one.
