IMPROVEMENTS IN THE CONSTRUCTION OF FLEXIBLE SHAFTS
Year: 1885

page_text: We, HENRY WALLEY and THOMAS GARE of N° 6 Hopwood Avenue Market
Place Manchester in the County of Lancaster Machinists and Merchants do hereby
declare the nature of our invention for "IMPROVEMENTS IN THE CONSTRUCTION OF
FLEXIBLE SHAFTS " to be as follows:-
Our invention relates to the construction of flexible shafts and has for its object
to construct a flexible shaft in which great strength durability and simplicity are
combined with great flexibility.
To this end we suitably produce a hollow flexible shaft, by winding a single
layer of wire of flat section, either on the edge or on the flat closely together or by
winding two layers of wire close on each other in one direction, the inner layer
being of a flat section wound on the edge or on the flat, and the outer layer being
of a flat section, but wound on the flat, or the latter may be of a circular section.

page_text: We HENRY WALLEY and THOMAS GARE of N° 6 Hopwood Avenue Market
Place, Manchester in the County of Lancaster, Machinists and Merchants, 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:-
Our invention relates to the construction of flexible shafts and has for its object
to construct a flexible shaft in which great strength, durability, and simplicity are
combined with great flexibility.
And in order that our invention may be better understood we have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1. 3. 5 and 7 are longitudinal, and Figs. 2. 4, 6. and 8 are cross sections of
our improved construction of flexible shaft.
In carrying out our invention we produce or form by suitable means, a hollow
flexible shaft, by winding closely together a single layer of wire a, of flat section,
either on the edge, as shown in Figs. 1 and 2, or on the flat as shown in Figs. 3 & 4,
or by winding two layers of wire b and c, close on each other in one direction, see
Figs. 5 & 6, the inner layer b, being of a flat section wound on the edge or on the
flat, and the outer layer c, being of a flat section but wound on the flat, or the
outer layer of wire c, may be of a circular section as shown in Figs. 7 & 8, or 1
vice versa.
The ends of such shaft are connected to the motive power source and the tool or
part to which rotary motion is to be imparted, in a manner well known, to suit
circumstances.
The great flexibility and strength in this construction of flexible shaft is
principally obtained by forming the shaft hollow, (instead of with a core, and wire
wound around it,) and by the employment of wire of flat section in the manner
described.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
A hollow flexible shaft formed by the employment of wire of flat section wound
closely together so as to form one layer, or the combination of an inner and outer
layer of wire substantially as described and set forth.

day of February A.D. 1886.
