AN IMPROVED FLANGE FOR WARP BEAMS OR ROLLERS
Year: 1884

page_text: I HENRY SHARP of Bolton-le-Moors in the County of Lancaster Engineer do
hereby declare the nature of said Invention for AN IMPROVED FLANGE FOR WARP
BEAMS OR ROLLERS to be as follows:-
The flanges at present used for warp beams or rollers are made of cast iron or
malleable cast iron the former are necessarily very heavy and liable to be broken
while malleable flanges are very expensive: the object of my Invention is to
overcome these faults by constructing a strong, light and inexpensive flange.
I make my improved warp beam or roller flange of mild steel or ingot iron by a
stamping process performed under hydraulic, steam or other pressure in the
following manner: I take a circular plate or disc of steel or iron and punch a hole
of the required size in the centre: this plate either hot or cold is next laid upon a
die and a ram or punch is used to force the metal around the hole outward in
order to form a boss; by this, means I am able to produce a strong and light
flange.
In applying my improved flanges to what are known as tube beams or rollers,
I make the outer diameter of the boss about the same as the hole in the tube and
then force the boss of a flange into each end of the warp beam or roller or the tube
may be secured inside the boss of each flange and allowed to project at one or both
ends if desired.
My improved flanges can be secured to wooden beams or rollers in any convenient
manner.

page_text: I HENRY SHARP, of Bolton-le-Moors, in the County of Lancaster, Engineer, do
hereby declare the nature of said Invention for AN IMPROVED FLANGE FOR WARP
BEAMS OR ROLLERS, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The flanges at present used for warp beams or rollers are made of cast iron, or
malleable cast iron; the former are necessarily very heavy and liable to be broken,
while malleable flanges are very expensive: the object of my Invention is to
overcome these faults by constructing a strong, light and inexpensive flange.
To accomplish this I make my improved warp beam or roller flange of mild steel
or ingot iron by a stamping process performed under hydraulic steam or other
pressure in the following manner :-
I take a circular plate or disc of steel or iron and punch or otherwise form a hole
of the required size in the centre; this plate either hot or cold is next laid upon a
'die, and a ram or punch is used to force the metal around the whole outward
in order to form a boss; by this means I am able to produce a strong and light
flange.
:
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings, reference
being had to the figures and letters marked thereon.
Figures 1 and 2 are elevations partly in section, of the machine I employ for
stamping out or making my improved flange for warp beams or rollers. Fig.
shows the punch raised and the disc of steel or iron in position on the die. Fig. 2
represents the punch down, and the flange finished.
In these views, a is the circular steel or iron plate or dise with a hole punched or
otherwise formed in the centre and b is the dio with a hole in the centre and
recessed at b¹ to fit the periphery of the plate a; the die b is secured to the frame c
to which are also secured the standards d which act as guides for the bracket o,
fixed to the piston rod or hydraulic ram f; the end of the rod or ram fis free to
slide in a recess made to fit it in the upper side of a circular metal block 9; the
head of the punch h is free to slide in a similar recess in the lower side of the
block, and the stem of the punch 7 passes through a hole between the two recesses
and is secured to the rod or ram f by a cotter pin i, and thus connects the block g
to the rod or ram f.
When the rod or ram fhas raised the block g and punch h into the position
shown in Fig. 1, the circular plate a is laid in the recess 6' on the die b, and when
the rod or ram f descends the circular block g rests upon the plate a, and as the
rod or ram f continues its stroke the head of the punch h is forced through the
hole in the plate a and the metal around the hole forced downward so as to form
a boss for the flange. The weight of the block g pressing on the metal around the
hole in the plate a keeps the same from twisting or buckling.
When the rod or ram fagain rises the punch his withdrawn from the flange a
and the block g raised, when the flange may be removed.
In applying my improved flanges to what are known as tube beams or rollers,
I make the outer diameter of the boss about the same as the hole in the tube, and
then force the boss of a flange into each end of the warp beam or roller, or the
tube may be secured inside the boss of each flange, and allowed to project at one or
both ends if desired.
My improved flanges can be secured to wooden beams or rollers in any convenient
manner.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed
I declare that what I claim is―
The manufacture of warp beam or roller flanges from eircular plates of steel or
iron by stamping or punching substantially in the manner and for the purposes
herein described and as illustrated by the accompanying Drawings.
