Improvements in the Construction of Card-cylinders for Jacquards.
Year: 1887

page_text: Improvements in the Construction of Card-cylinders for Jacquards.
I, JOHN EDWARD WADSWORTH, of Oldham Road, Newton Heath, Manchester, do
hereby declare the nature of this invention to be as follows:-
The improvements relate to the construction of card-cylinders for jacquards, and
have for object the production of cylinders less liable to get out of truth than the
wooden cylinders at present in use, and less clumsy, or less difficult to produce than
the metallic cylinders which are at present employed.
To accomplish this and to effect my improvements, I employ what is known as
solid drawn metallic tubing, four or more sided in cross section, and, by preference,
of brass, but other metals may be employed.
A piece of such tubing is cut to the required length for a cylinder, and the cast or
other metal cylinder ends are formed so as to be inserted within such tube as far as is
requisite, and secured therein by means of pins, screws, rivets, keys, or by shrinkage.
By this means a light, true, and strong cylinder may be produced at a comparatively
small cost.
The holes necessary to be drilled in the sides of the cylinder, and the attachment of
the pegs for the cards, may be made either before or after the solid drawn tube is
attached to the cylinder ends, as may be most convenient; and variations in detail
and form may be made without departing from the peculiar character of the
invention, which mainly consists in the employment of what are known as solid drawn
metallic tubes, four or more sided in cross section, in the construction of card-
cylinders for jacquards.

Improvements in the Construction of Card Cylinders for Jacquards.
I JOHN EDWARD WADSWORTH of 540 Oldham Road Newton Heath near
Manchester Mechanic 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 improvements relate to the construction of Card Cylinders for Jacquards and 5
have for object the production of Cylinders less liable to get out of truth than the
wooden Cylinder at present in use, and less clumsy or less difficult to produce than the
Metallic Cylinders which are at present employed, to accomplish this and to effect my
improvements I employ what is known as solid drawn metallic tubing, four or more
sides in cross sections, and by preference of brass, but other metals may be employed.
A piece of such tubing is cut to the required length for a Cylinder and the cast, or
other Metal Cylinder ends are formed so as to be inserted within such tube as far as
requisite and secured therein by means of pins, screws, rivets, keys, or by shrinkage,
by this means a light true and strong Cylinder may be produced at a comparatively
small cost, the holes necessary to be drilled in the sides of the Cylinder and the I
attachment of the Pegs for the Cards, may be made either before or after the solid
drawn tube is attached to the Cylinder ends, as may be most convenient, and
variations in detail and form may be made without departing from the peculiar
character of the invention which mainly consists in the employment of what are
known as solid drawn metallic tubes, four or more sided in cross sections in the 2
construction of Card Cylinders for Jacquard Machines, but that the improvements
may be better understood I will by the aid of the accompanying drawings, proceed
more fully to describe means employed by me.
DESCRIPTION OF DRAWINGS.
Fig. 1 shows end view of square metallic tubing with cast metal Cylinder end 2
inserted Fig. 2 & 3 end view cross section metallic tubing Fig. 4 front view with
cast metal Cylinder ends inserted.
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 construction of solid drawn metallic tubing Jacquard Card Cylinder with cast
metal ends inserted four or more sided in cross sections as shown and described.
