I, JOHNSON MILLS, of Victoria Buildings, Manchester, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention relates to flanges and unions for steam pipes, hydraulic water tube
pipes and like uses, and the object of this invention is to dispense with the couplings
such as are ordinarily required when wrought iron flanges are employed.
In this invention I construct either a flange or a union from a bloom of steel,
by stamping in suitable dies by means of a drop or a steam hammer or other forces,
a flange or a union in which either recessed rings or projections may at the same
time be formed on the face thereof.
Dated this 18th day of March 1893.

COMPLETE SPECIFICATION.
Improvements in Flanges and Unions for Steam Pipes, Hydraulic
Water Tube Pipes, and like uses.
1, JOHNSON MILLS, of Victoria Buildings, Manchester, in the County of
Lancaster, Engineer, 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 :-
This invention relates to flanges and unions for steam pipes, hydraulic water tube
pipes and like uses, and the object of this invention is to dispense with the couplings
and wrought or cast metal flanges, such as are ordinarily employed.
In the accompanying drawing,
Fig. 1 represents a plan, and Fig. 2 an edge view of a flange constructed
according to this invention.
Fig. 3 represents my invention applied for connecting a pipe to an elbow or
bend.
In these views similar letters refer to similar parts.
In this invention I construct a flange or union such as a, from a bloom of steel
or iron, by stamping in suitable dies by means either of a drop hammer or other
forces, a flange or union on which projections such as are at the same time formed
on the face thereof, in which holes may be drilled through which to pass bolts for
connecting said flanges in the manner shown in Fig. 3, the end of the pipe and
the bend d being screwed into, or rivetted to the flanges a.
The projections may vary in number, and the contour or outline of the
aforesaid flange may be varied to suit special requirements.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim :-
A flange or union for connecting steam pipes; hydraulic water tube pipes, and

page_text: like uses, with projections such as shown on drawing, said flange being formed
from a bloom of steel or iron by stamping in suitable dies, either by means of a
drop hammer or by other forces, substantially as herein before described.
Dated this 19th day of December 1893.
