PROVISIONAL SPECIFICATION.
Improvements in Carding Engines.
I, BENJAMIN ALFRED DOBSON, of Kay Street Works, Bolton, in the County of
Lancaster, Machine Maker, do hereby declare the nature of this Invention to
be as follows:-
My invention relates to the setting and regulating of the travelling flats of
carding engines, and consists in combining what is commonly termed the five
setting point flexible bend and the one setting point flexible bend as respectively
described in William Dobson's Patent No. 7068 of 1885 and Dobson and Bromiley's
Patent No. 874 of 1886, my object being to allow the attendant to set or regulate
the flexible bend at independent points or from one point as required.
In carrying my Invention into effect several of the essential features described
in Patent No. 874 of 1886 are retained, but instead of rigidly fixing the curved
brackets upon which the pins of the flexible bend slide, to the stationary bend
or framing, I make them adjustable by means of regulating screws or other suit-
able appliances, and I provide the brackets with curved slots in which the pins of
the flexible bend move when adjusted.
The pivoted lever at one end of the flexible bend is retained, but the dial and
rack at the other end may be dispensed with and replaced by a fine threaded screw
provided with lock nuts and passing through any convenient fixed part such as
the card framing.

Improvements in Carding Engines.
I, Sir BENJAMIN ALFRED DOBSON, Knight, of Kay Street Works, Bolton, in
the County of Lancaster, Machine Maker, 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:-
My invention relates to the setting and regulation of the travelling flats of
carding engines, and consists in combining what is commonly termed the five
setting point flexible bend and the one setting point flexible bend as respectively
described in William Dobson's Patent No. 7068 of 1885 and Dobson and Bromiley's
Patent No. 874 of 1886, my object being to allow the attendant to set or regulate
the flexible bend at independent points or from one point as required.
In carrying my Invention into effect several of the essential features described

page_text: in Patent No. 874 of 1886 are retained, but instead of rigidly fixing the curved
brackets upon which the pins of the flexible bend slide, to the stationary bend
or framing, I make them adjustable by means of regulating screws or other suit-
able appliances, and I provide the brackets with curved slots in which the pins of
the flexible bend move when adjusted.
The pivoted lever at one end of the flexible bend is retained, but the dial and
rack at the other end may be dispensed with and replaced by a fine threaded screw
provided with lock nuts and passing through any convenient fixed part such as
the card framing.
In the accompanying Sheet of Drawings-
Figure 1 is a side elevation of part of a carding engine fitted with my present
improvements, and Fig. 2 is a transverse section of the same.
In these views, a designates the main cylinder of the carding engine, 6 the
engine bend or stationary framing, e the flexible bend, the link or lever con-
necting the flexible to the engine bend b and c¹ the pins on the flexible which
bear on the curved or inclined surfaces of the slots c¹ which I make in the
brackets e and which act as setting points for the flexible.
After adjustment each
Instead of securing the brackets e to the engine bend b by two bolts f and so
making them rigid and unadjustable as in Patent No. 874 of 1886, I now make
each bracket adjustable by means of a regulating screw g and locknuts the
screw passing through the flange on the engine bend.
bracket e is fixed in position by means of a single bolt f.
The flexible c is moved endwise for adjusting purposes by means of a screw i
pivoted to it and which passes through the under framing of the carding engine
and is secured by locknuts j.
The end brackets k m which carry the slides no for the front and back centres
or carriers respectively round which the flats travel are each rigidly bolted to
the engine bend b by bolts f¹. In the slide » I form a curved slot a similar to the
slots to receive a pin fixed on the flexible and on which pin is pivoted the
link by which the flexible is connected to the engine bend and in the slide o
also I form a curved slot o¹ to receive another pin fixed on the flexible, and to
each slide no I connect a regulating serew g with locknuts . By slackening
the locknuts when the flexible is moved endwise I can simultaneously adjust
the positions of the slides no and consequently of the front and back centres by
means of the pins moving in the curved slots n' o'.
It will be obvious, that although I have only described my improvements as
applied to the flexible bend on one side of the carding engine a similar arrange-
ment will be applied to the flexible on the other side.
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 combination with the flexible bends provided with pins or projections
and the brackets and slides formed with curved slots therein en which said pins
slide when the flexibles are moved endwise for adjustment, of the regulating
serews or equivalent appliances for adjusting said brackets and slides substantially
as herein set forth.
2. The general combination and arrangement of parts embodying my improve-
ments in carding engines substantially as herein described and as illustrated by
the accompanying Drawing
