IMPROVEMENTS IN CARDING ENGINES
Year: 1884

page_text: I WILLIAM DOBSON, of 20 Derby Square, Douglas, Isle of Man and also of
Bolton, in the County of Lancaster, Engineer, do hereby declare the nature of said
Invention for IMPROVEMENTS IN CARDING ENGINES, to be as follows:-.
My invention consists of an improved method, first, of setting and regulating the
concentric bend or flexibles upon which the flats work in carding engines and
secondly, of adjusting the position of the main cylinder to the flats at work on the
said bend..
In performing the first part of my invention I connect to the concentric bend or
flexible of a carding engine three or more arms or levers which are fastened at
their other ends to the framing of the carding engine at each side. The levers are
of varying length, number one, for instance, being the shortest, number two a little
longer, number three a little longer still and so on, and the object of it is that by
moving one of these levers the positions of the other levers are altered and the
bend is drawn in and the diameter of its circle lessened and it is kept perfectly
and thoroughly concentric in every position..
When the bend is at its highest point number one, or the shortest lever, may be
radial to the cylinder and the lines of the centres of the other levers may pass
above the centre of the carding engine cylinder at varying angles. The more levers
I apply to the concentric bend the more points of that bend are absolutely fixed
concentrically with the cylinder and the less chance of error due to the springing
of the cast iron or other material of, which the bend is constructed, between the
points of regulation.
do not tie myself to any particular number of levers.
By this arrangement when one lever is moved the relative position of each of the
other levers is also moved and the bend is always kept concentric with the main
cylinder.
In performing the second part of my Invention, I fit inside each pedestal block
two eccentrics, (the one near cylinder shaft preferably of brass) in which the
cylinder shaft turns: when by long use the bearings bave worn sufficiently to
render the centre of the cylinder untrue with the fixings and flats I adjust the
position of the cylinder by turning one or other or both of the eccentrics in each of
the pedestals and when the cylinder has been brought into its proper position
I lock the parts with a suitable arrangement of bolts or otherwise.
My invention relates particularly to revolving carding engines, but is applicable
to carding engines of other descriptions.

page_text: COMPLETE SPECIFICATION,
I WILLIAM DOBSON, of 20 Derby Square, Douglas, Isle of Man, and also of
Bolton in the County of Lancaster, Engineer, do hereby declare the nature of said
Invention for IMPROVEMENTS IN CARDING ENGINES," and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:—
My invention consists of an improved method of setting and regulating the
concentric bend or flexibles upon which the flats work in carding engines.
In performing my Invention I connect to the concentric bend or flexible of a
carding engine three or more arms or levers which are fastened at their other ends
to the framing of the carding engine at each side. The levers are of varying
length, number one, for instance, being the shortest, number two a little longer,
number three a little longer still and so on, and the object of it is that by moving
one of these levers the positions of the other levers are altered and the bend is
drawn in and the diameter of its circle lessened and it is kept perfectly and
thoroughly concentric in every position..
When the bend is at its highest point, number one, or the shortest lever may be
radial to the cylinder and the lines of the centres of the other levers may.pass
above the centre of the carding engine cylinder at varying angles. The more
levers I apply to the concentric bend the more points of that bend are absolutely
fixed concentrically with the cylinder and the less chance of error due to the
springing of the cast iron or other material, of which the bend is constructed,
between the points of regulation,
I do not tie myself to any particular number of levers.
By this arrangement when one lever is moved the relative position of each of
the other levers is also moved and the bend is always kept concentric with the
main cylinder.
My invention relates particularly to revolving carding engines but is applicable
to carding engines of other descriptions.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawing which illustrates
my improved method of and means for setting or adjusting the concentric bend or
flexible of a carding engine.
a is the concentric bend or flexible to which are pivoted the five arms or
levers bbb 63 b' of which bis the shortest and the longest; the other ends of
these levers are pivoted to the engine bend or framing c; the lever b is radial to
the cylinder when the bend a is at its highest point as shown in full lines on the
Drawing; d is a screw on which are lock nuts and which passes through a lug or
projection c¹ formed on the engine bend c, by turning the screw d the lever b' may
be moved thereby moving the concentric bend or flexible a and the other levers
and concentrically drawing in the flexible a into the position indicated by dotted
lines.
In place of the screw d any suitable device may be employed for moving the
lever b' when adjusting the position of the flexible.

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
1. The method of setting and regulating the concentric bend or flexible of a
carding engine by means of arms or levers pivoted or connected to the said
concentric bend or flexible and to the engine bend or framing, substantially in the
manner herein set forth for the purposes specified.
2. The arms or levers bb bbb substantially as and for the purposes herein
shown and described.
