PROVISIONAL SPECIFICATION.
Improvements in the Feed Regulators of Machines for Opening and
Cleaning Cotton and other Fibrous Materials.
I, BENJAMIN ALFRED DOBSON, Machinist, of Kay Street Works, Bolton, in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in connection with the antifriction bowls
or runners and pendants or fish tails used in connection with the feed regulators
of machines for opening and cleaning cotton and other fibrous materials, and the
chief object of my improvements is to minimise friction in the working of the bowls
and pendants so as to render the feed regulator more sensitive.
In carrying my improvements into effect I place three antifriction bowls or
runners between each pair of pendants. These three bowls are all of equal diameter
and are mounted loosely and concentrically upon a pin or stud the ends of which
are preferably extended and are guided in slides or grooves in the lever box or bowl
rail, or additional loose runners may be used on the ends of the stud to run in
these slides or grooves. One side or face of each pendant has a mid-rib or pro-
jecting surface which bears on the face of the middle runner, so that as the pendant
is moved up and down it is kept by this rib out of contact with the two side runners.
The other side or face of the pendant is grooved in mid-width in order that it may
bear on the two side runners of the next series of three bowls without coming into
contact with the middle runner. Each pendant laving one face with a mid-rib
and the other with a groove is therefore free to move in contact with bowls or
runners which are of equal diameter without interfering with the movement of the
next pendant whereby a simplified and sensitive movement is obtained for regulat-
ing purposes.

Improvements in the Feed Regulators of Machines for Opening and
Cleaning Cotton and other Fibrous Materials.
I, Sir BENJAMIN ALFRED DOBSON, Knight, of Kay Street Works, Bolton, in the
County of Lancaster, Machinist. do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-

page_text: of machines for opening and cleaning cotton and other fibrous materials, and the
chief object of my improvements is to minimise friction in the working of the bowls
and pendants so as to render the feed regulator more sensitive.
In carrying my improvements into effect 1 place three antifriction bowls or
runners between each pair of pendants.
The accompanying sheet of drawings illustrates the application of my improve-
ments Figure 1 being an elevation of part of the bowl rail of the feed regulator of
a cotton opener or similar machine. Fig. 2 a sectional plan of Fig. 1, Fig. 2^ a
section of one half of the bowl rail showing additional loose runner, and Figs. 3, 4
and 4 similar views to Figs. 1, 2 and 2 respectively of a slightly different
arrangement.
In these views. 1 denotes the bowl rail, 2 one of the usual series of pendants
or fish tail levers, 3 the pin or stud and 4 the antifriction bowls or runners
of which place three between each pair of pendants as already stated. These
three bowls 4 are all of equal diameter and are mounted loosely and concentrically
upon the pin or stud 3 the ends of which are preferably extended and as shown in
Figs. 4 and 4, are guided in slides or grooves 5 in the bowl rail, or as shown in
Figs. 2 and 24, additional loose runners 4 may be used on the ends of the stud 3
to run on the ledge 5". One side or face of each pendant 2 has a mid-rib or pro-
jecting surface 6 which bears on the face of the middle runner 4, see Figs. 2 and 4,
so that as the pendant is moved up and down it is kept by this rib 6 out of contact
with the two side runners 4. The other side or face of the pendant is grooved
at 7 in mid-width in order that it may bear on the two side runners of the next
series of three bowls 4 without coming into contact with the middle runner. Each
pendant having one face with a mid-rib 6 and the other with a groove 7 is
therefore free to move in contact with bowls or runners 4 which are of equal dia-
meter without interfering with the movement of the next pendant whereby a
simplified and sensitive movement is obtained for regulating purposes.
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. In combination, the pendants or fish tail levers, each having a projecting
mid-rib on one side and a groove in mid-width on the other side, a pin or stud
placed between each pair of said pendants, three anti-friction bowls or runners all
of equal diameter and mounted loosely and concentrically upon the said pin or stud
and means for supporting and guiding the ends of the pin or stud in the lever box
substantially as herein set forth.
2. The combination and arrangement of parts embodying my improvements
substantially as herein described and as illustrated by Figs. 1, 2 and 24.
3. The combination and arrangement of parts embodying my improvements sub-
stantially as herein described and as illustrated by Figs. 3, 4 and 4*.
