Improvements in Carding Engines with Revolving Flats.
I, WILLIAM BARKER of 256 Firtree Terrace, Gorton Road, Reddish in the County
of Lancaster, engineer 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 carding engines with revolving flats and consists in an
improved method of or arrangement for supporting the flats above the carding engine
cylinder. Ordinarily the flats are supported on stationary adjustable bends on which
they slide. My improvement consists in supporting the flats in adjustable brackets
fixed to discs or circular bends arranged on each side of the cylinder and free to turn
upon the cylinder shaft or a boss of the cylinder pedestal, which discs or bends are
taken round by the chain of flats during its travel.
On the sheet of drawings apponded hereunto figure 1 shows a side view of the
revolving bend and chain of flats. Only a part of the brackets are shewn, the
remainder being indicated by their centre lines. Of the chain of flats also only part
is shewn, the reuninder being indicated by dotted lines, and the flats resting in the
adjustable brackets are shewn with the links connecting them removed.
Fig. 2 shows a cross section through the revolving bends.
Fig. 3 shows an end view and fig. 4 a side view of the adjustable bracket and flat
on an enlarged scale.
Only those parts of the carding engine are shewn that are necessary for ascertaining
the nature of my invention, all others being omitted.
Upon the shaft a of the cylinder I place on each side of said cylinder a disc c
fitted with a brass bush d with collar to keep the disc or bend clear of the cylinder
end. The bends c are formed with rims drilled for the reception of the adjustable
brackets ee and stiffened by webs c². Instead of the bends being placed on the shaft
they may be placed on turned bosses formed on the side of the cylinder pedestals
concentrically with the shaft. Instead of casting the disc in one piece as shewn, it
may be made in two semicircular halves bolted together by means of flanges, or be
made of sheet and angle iron or steel instead of being cast. The adjustable brackets e
I make by preference as shewn with a shoe e¹ for the reception of the flat, forged in

page_text: one piece with the screwed shank e, with a nut outside and another locknut f¹
inside the rim c¹ by means of which lock nuts the distance of the shoe from the
periphery of the bend c or cylinder can be regulated. The shoe is forked as shewn
し
by fig. 3, the sides of the fork being inclined towards each other. The flats g are
recessed at the sides at the parts coming upon the shoes and shaped to fit into the
bottom of the forks, whereby their position with regard to the cylinder is secured.
They are connected outside the shoes by links hon studs i screwed into the ends of
the flats or by equivalent means so as to form a chain as usual, which passes round the
driving chain pulley k and the guide pulleys and m, on each side of the carding
engine. Fixed bends are mounted as usual upon the engine frames outside the
revolving bends c and carry the brackets for the pulleys k, and m and other
parts.
I
As the chain of flats travels along, the recessed parts of the flats y enter the forks
of the shoes e¹ in succession at the pulley m and carry the bends c round with them,
leaving the forks again at the driving pulley k. The pitch of the forks or brackets e
is of course the same as that of the Hats or links, the links having a small amount of
play and the shoes e' a small amount of clearance between each other to allow of their
adjustment to a smaller radius from the centre.
Instead of the shoo e¹ being forged solid with the studs and adjusted on the rim c¹,
the shoes may be formed on flat brackets bolted to the side of the discs c which are in
that case made without rims c'. The brackets are held between planed ledges formed
on the discs so that their centre lines are radial and adjusted by screws passing through
eyes or their equivalent attached to the discs, locking devices being provided, or the
brackets may be mounted upon separate slides attached to the dises in a similar manner
as the brackets for the rollers and clearers of roller carding engines are mounted upon
the bends.
Having now particularly described and ascertained the naturo of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
Firstly, in revolving flat carding engines supporting the flats on adjustable brackets
fixed upon discs revolved on the cylinder shaft or pedestal by the chain of flats,
substantially as hereinbefore described.
Secondly, the arrangement of brackets e discs c and flats g substantially as herein
before described and shewn on the drawings and for the purpose set forth.
