Year: 1880

page_text: LETTERS PATENT to Herbert John Haddan, of the Firm of Herbert and
Company, Solicitors of Patents, of 67, Strand, in the City of Westminster,
Civil Engineer, for an Invention of "SINTZEUICH'S IMPROVEMENTS IN THE
MANUFACTURE OF RAILWAY RAILS." A communication from abroad by
Horace Henry Charles Sintzeuich, of the City of Toronto, in the County of
York, in the Province of Ontario, Dominion of Canada, Civil Engineer,
Inventor.
COMPLETE SPECIFICATION filed by the said Herbert John Haddan at the
Office of the Commissioners of Patents on the 26th May 1880.
HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. "SINTZEUICH'S
IMPROVEMENTS IN THE MANUFACTURE OF RAILWAY RAILS." A communication
from abroad by Horace Henry Charles Sintzeuich, of the City of Toronto, in the
County of York, in the Province of Ontario, Dominion of Canada, Civil Engineer,
Inventor.
The Invention relates to method of rolling rails in such a manner as to produce
ridges projecting downwards from the outer edges of the head of the rails, and
similar ridges projecting upwards from the outer edge of the table of the rails, so as
to form grooves adapted to hold sliding bars to unite the ends of the rails in
substitution for the fish plate joint.
My Invention consists in producing these ridges by the use of rolls so formed as
to produce a ridge or corner suitable for being bent into the desired position in
combination with a succeeding roll so formed as to exert an inward bending
pressure upon the metal forming such ridges or corners.
Finally, it consists in the rolled rail with grooves or chambers suitable for
holding sliding bars for the purposes described, resulting from the process
described.
In the accompanying Drawings, in which similar letters of reference indicate like
parts, Figure 1 is an elevation section of a part or fragment of a pair of rolls,
shewing a figure to be cut in the rolls to place the metal in ridges or corners ready
for the bending action of the following inward pressing rolls; Figure 2 is an
elevation section of a part or fragment of the final pair of rolls by which the ridges
are bent into the desired position.

page_text: In Figure 3 the dotted line shews the corners or ridges applied to a rail of a
different shape from that in Figure 1, the general form of rail shewn in Figures 1.
and 2 being that commonly used in the United States of America, and that shewn
in Figure 3 being the rail commonly used in Great Britain.
Figure 4 shows an elevation of a pair of rolls containing the cuts, Figures 1
and 2.
It is obvious that the exact form and proportions of parts of the ridges and the
rail generally may be considerably altered while the principle of my Invention is
still followed.
In rolling rails in the above method the same general process of rolling will be
followed as is now customary in rolling mills, and the majority of the rolls as now
used in rolling rails namely, the muck rolls, and all but the last two or three
finishing rolls may continue to be used with little or no alteration.
In the last roll, Figure 2, the whole acting pressure is exerted upon the corners
or ridges for the purposes of bending the ridges around into the desired position,
the shape of the roll being such as to exert no pressure upon the head, table, and
that part of the web of the rail which is touched, but only fitting the rail at these
surfaces so as to prevent its general shape becoming distorted by the pressure upon
the surface of the ridges.
Having thus described my Invention, what I claim and desire to secure by
Letters Patent is,―
First. The herein before described process of forming grooved or chambered rails
by forming and bending ridges of metal, substantially as described.
Second. The combination with a train of rail rolls of the rolls containing
Figures 1 and 2, arranged and operating substantially as and for the purposes
described.
Third. A railway rail with grooves formed by pressure, substantially as
described.
In witness whereof, I, the said Herbert John Haddan, have hereunto set
my hand and seal, this Twenty fifth day of May, A.D. 1880.
H. J. HADDAN. (L.S.)
