PROVISIONAL SPECIFICATION.
Improvements in Travelling Flat Carding Engines.
I, HERBERT MASON, of No. 40, Uhlandstrasse, Dresden, in the Empire of
Germany, Textile Engineer do hereby declare the nature of this invention to be
as follows:-
My invention relates to improvements in travelling flat carding engines and
the object of my improvements is to provide a simple and efficient arrangement
for adjusting and setting the flexible bends concentrically to the main cylinder
of the carding engine.
In carrying my improvements into effect I connect the flexible on each side
of the engine by five pin jointed brackets to the engine bend or stationary side
framing. All the brackets are secured to the engine bend by bolts passing hori-
zontally through them.
The five pins upon which the brackets are jointed are set out at equal distances
apart and cach of the brackets except the middle one is connected by means of
an adjustable rod or link to a ring or rings fitted to slide circumferentially on
the bearing of the main cylinder shaft. The middle bracket is connected for
adjusting purposes by a screwed rod and locknuts to the,ril on the engine bend
but as this bracket is only required to move vertically up or down, the bolt which
secures it passes horizontally through a hole in the engine bend whereas the
bolts for the other brackets which have a circumferential as well as a radial
movement during adjustment-pass through slots in the engine bend.
When it is necessary to draw down the flexible in order to compensate for wear
of the card wire on the cylinder or flats, the middle of the flexible is first of all
lowered to its right height by means of the middle bracket which, as already
stated, is only free to move vertically up or down, then the other four setting
points are gradually drawn in by adjusting the connecting rods or links of the
other four brackets until the flexible bend on each side of the engine forms part
of a true circle concentric with the main cylinder.
The chief features of this arrangement of setting are that when lowering the
flexible, and its new position on a smaller circle occupies a larger portion of the
circle than it did in its previous position, that the two pins on each side of the
middle one do not fall radially alone, but circumferentially as well as radially,
and that cach setting point is adjusted separately to the dead centre of the
flexible and main cylinder.
I have described the use of five pins and setting points, but I wish it to be
understood that I do not confine myself to that number although I consider it
to be the most suitable for my purpose.
Dated this 23rd day of June 1899.

I, HERBERT MASON, of No. 40, Uhlandstrasse, Dresden, in the Empire of
Germany, Textile 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 improvements in travelling flat carding engines, and
the object of my improvements is to provide a simple and efficient arrangement
for adjusting and setting the flexible bends concentrically to the main cylinder
of the carding engine.
In carrying my improvements into effect I connect the flexible on each side
of the engine by five pin jointed brackets to the engine bend or stationary side
framing. All the brackets are secured to the engine bend by bolts passing hori-
zontally through them.
The five pins upon which the brackets are jointed are set out at equal distances
apart and each of the brackets except the middle one is connected by means of
an adjustable rod or link to a ring or rings, fitted to slide circumferentially on
the bearing of the main cylinder shaft. The middle bracket is connected for
adjusting purposes by a screwed rod and locknuts to the rib on the engine bend
but as this bracket is only required to move vertically up or down the bolt which
secures it passes horizontally through a radial slot in the bracket and a hole in
the engine bend whereas the bolts for the other brackets which have a circum-
ferential as well as a radial movement during adjustment-pass through slots
in the engine, bend.
In the accompanying sheet of drawings:-
Figure 1 is a sectional end elevation of the upper part of one side framing of
a travelling flat carding engine, and Figure 2 is a side elevation of the same
illustrating my improved arrangement for setting the flexible bends concentric-
aily to the main cylinder of the carding engine.
In these views, 2 denotes one of the engine bends or stationary side frames,
3 one of the flexible bends, 4 the middle bracket connected by a pin joint at 5
to the flexible at or about mid-length and by a screwed rod or shank 6 and lock-
nuts 7 to the rib 8 of the engine bend. The bracket 4 has a radial slot through
which and a hole in the engine bend a bolt 9 passes in order to secure the bracket
after adjustment. The remaining four brackets 10, 11, 12 and 13 are all pin
jointed at 5 to the flexible 3, and are connected respectively by screwed adjusting
rods or links 14, 15, 16 and 17 to the rings 19, 20, 18, and 21 fitted to turn or
slide circumferentially on the bearing of the main cylinder shaft 22. In the
arrangement illustrated the rings 18, 19 and 20 are double rings while the ring 21
is a single ring but made of twice the thickness to compensate in strength. The
bolts 9 pass through radial slots in their respective brackets 10, 11, 12 and 13
and also pass through slots in the engine bend and the connecting rods or links 14,
15, 16 and 17 pass through slots or openings in the rib 8 so as to permit a cir-
cumferential as well as a radial movement of the brackets 10, 11, 12 and 13
during adjustment.
When it is necessary to draw down the flexible 3 in order to compensate for
wear of the cardwire ou the cylinder or flats, the bolts 9, are all slackened, the
middle of the flexible is first of all lowered to its right height by means of the
middle bracket 4 which, as already stated, is only free to move vertically up or
down, then the other four setting points are gradually drawn in by adjusting the
connecting rods or links 14, 15, 16 and 17 of the other four brackets until the
flexible bend 3 forms part of a true circle concentric with the main cylinder in

page_text: which position it is then firmly locked by again tightening up the bolts. The
adjustment is obtained by loosening lock nuts 23 on the pairs of rods 14 and 15
and turning the nuts 24, provided with right and left hand screw threads, in the
desired direction and then tightening the lock nuts 23.
In the alternative arrangement of rods 16 and 17 each rod has a right hand
thread at one end and a left hand thread at the other end and means, such as the
octagonal collars 25, for enabling the rods to be turned.
The flexible bend on the opposite side of the engine would be adjusted in like
manner.
The chief features of this arrangement of setting are that when lowering the
flexible, and its new position on a smaller circle occupies a larger portion of the
circle than it did in its previous position, that the two pins on each side of the
middle one do not fall radially alone, but circumferentially as well as radially,
and that each setting point is adjusted separately to the dead centre of the
flexible and main cylinder.
I have described the use of five pins and setting points, but I wish it to be
understood that I do not confine myself to that number although. I consider it
to be the most suitable for my purpose.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
1. The combination with the, flexible bend of a travelling flat carding engine,
of a middle bracket arranged to draw down the flexible radially and a series of
say four additional brackets arranged to draw in the flexible radially and also
to move with it circumferentially during adjustment all substantially as herein
set forth.
2. The general combination of parts, substantially as herein described and as
illustrated by the drawing, constituting an improved arrangement for adjusting
the flexible bends concentrically to the main cylinder of a travelling flat carding
engine.
