We, EDWARD COPE, Nut and Tube Manufacturer and ALFRED HOLLINGS, Manager,
of High Bank Steel Works Openshaw, Manchester, in the county of Lancaster, do
hereby declare the nature of this invention to be as follows:-
The first part of our invention consists in making from one hollow ingot or piece of
steel a length of hollow shafting with end compressed flanges, collars, projections or
like devices.
Under the second part, namely, the manufacture, a heated hollow ingot or hollow
cheese is drawn between rolls over stationary mandrels or otherwise made into a
hollow parallel shaft the required size and section. The metal is drifted or forced by
hydraulic end pressure upon itself until the desired flanges, collars, projections or like
devices are forined in the required positions.

Improvements in Hollow Steel Shafting and in the Manufacture of
the same.
We EDWARD COPE Nut and Tube Manufacturer and ALFRED HOLLINGS Manager
of High Bank Steel Works Openshaw Manchester in the county of Lancaster, 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:-
The first part of our invention consists in making from one hollow ingot or piece of
steel a length of hollow shafting with end compressed flanges, collars, projections or
like devices.
Under the second part, namely the manufacture, a heated ingot or hollow cheese is
drawn between rolls over stationary mandrels or otherwise made into a hollow parallel
shaft of the required size and section. The metal, is drifted or forced by hydraulic
end pressure, up
upon
itself until the desired flanges collars projections, or like devices
are formed in the required positions.
In order that our invention may be readily understood, we have appended a sheet
of drawings illustrating the method of carrying our invention into effect.
Fig. 1 shows in vertical section a rolled hollow ingot and figs. 2 3 & 4 longitudinal
sections of hollow shafts respectively with end flange collars and projection.
These are each marked a and are formed or effected during one or more heats.
Figs. 5 and 6 are sections at right angles to each other of dies which are placed
around the hollow shaft on the body side near where the flanges collars or projections
are to be formed.
The metal is heated at the parts when the compression is to take place and mandrels
ordinarily used in conjunction with the dies. Any type of suitable hydraulic press
is used.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
First. Hollow shafting made from a hollow ingot or piece of steel with end
compressed flanges, collars, projections, or like devices.
Second. The manufacture of shafting by heating a hollow ingot or cheese, drawing
the same between rolls, and applying hydraulic end pressure substantially in th
manner and for the purpose set forth.
