Improvements in Apparatus for use in Rolling Tubes and Hollow
Articles.
We EDWARD COPE of No. 30 Grey Street Openshaw Manchester in the County
of Lancaster, Nut and Tube Manufacturer, and ALFRED HOLLINGS of the same
place, Works Manager do hereby declare the nature of this invention to be as
follows:-
The object is to provide apparatus to facilitate the operation of rolling tubes and
hollow shafts and like hollow articles especially when such articles are of large
diameters and heavy mandrels are required.
Apparatus under our invention consists essentially (a) of rolls provided with
tables or carriers at both sides so that articles are rolled whilst being passed in both
directions at or about the same level, (b) of hydraulic or other power apparatus for
moving into position from one groove to another of the rolls and for pushing forward
the articles to be rolled, (c) of hydraulic or other power apparatus for advancing
the mandrels into position to receive the hollow articles to be rolled and for
retracting the said mandrels after rolling, and (d) of means for anchoring the
mandrels whilst the hollow articles are passing through between the rolls.

COMPLETE SPECIFICATION.
Improvements in Apparatus for use in Rolling Tubes and Hollow
Articles.
We, EDWARD COPE of No. 30 Grey Street Openshaw, Manchester, in the
County of Lancaster, Nut & Tube Manufacturer, and ALFRED HOLLINGS of the
saine place, Works Manager, 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 object is to provide apparatus to facilitate the operation of rolling tubes and
hollow shafts and like hollow articles, especially when such articles are of large
diameters and heavy mandrels are required.
Apparatus under our invention consists essentially (a) of rolls provided with
tables or carriers at both sides so that articles are rolled whilst being passed in both
directions at or about the same level, (b) of hydraulic or other power apparatus for
moving into position from one groove to another of the rolls, and for pushing
forward the articles to be rolled, (c) of hydraulic or other power apparatus for
advancing the mandrels into position to receive the hollow articles to be rolled, and
for retracting the said mandrels after rolling, and (d) of means for anchoring the
mandrels whilst the hollow articles are passing through between the rolls.
DESCRIPTION OF THE DRAWINGS.

page_text: b b¹ are tables or carriers for the metal to be rolled at both sides of the rolls and the
same height. c c are cross bars free to be moved along the tables b b. The said
bars c c¹ are connected together by chains e which pass around pulleys, f, carried by
the framework, of the tables the chains e are connected to a crosshead g which
crosshead is coupled to the ram, h, of the hydraulic cylinder, i. By giving motion
to the ram and crosshead the bars c c¹ may be made to move along the tables so as
to push forward between the rolls the metal, j, to be rolled. k are hydraulic rams
for pushing the metal across the tables from one groove of the rolls to another.
The mandrels, l, are made hollow at the end so that they may be seized by
grippers, m, which said grippers are formed with clips n to fit over the cross
bars c c. By giving motion to the said crossbars and grippers the mandrels may
be pushed through the metal into position, or be withdrawn therefrom. At the
ends of the tables there are cross bars o o¹ the upper one of which carries a sliding
block p. to which is pivotted a lever g; from the lever y hangs a dog or clip r
which may be passed between the head of the mandrel and the cross bar o and end
of the table so as to anchor or hold the said mandrel in position.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is :-
:―
The combination of rollers and tables, with apparatus for moving the metal to be
operated on, and the mandrels, and for anchoring the mandrels, substantially as set
forth.
Dated this Fifth day of May 1893.
