Improvements in Means for Regulating the Feed of Fibrous Materials
to Opening Machines and certain other Machines employed in the
Preparation of Fibrous Materials for Spinning.
We, BENJAMIN ALFRED DOBSON, of Dobson and Barlow Limited, Kay Street
Works, Bolton, in the County of Lancaster, Engineer, and JOHN HENRY PICKUP,
of the same address, Foreman, do hereby declare the nature of this invention
to be as follows:-
Our invention relates to improvements in regulating mechanism of the type
described in the Specification to Musgrave and Cooper's Patent 11918 of 1894 (assigned
to Dobson and Barlow Limited, of Bolton) for automatically regulating the feed
of fibrous material to hoppers combined with opening machines and certain other
machines employed in the preparation of cotton and other fibrous materials for
spinning, and the object of our improvements is to simplify such mechanism and
render it more sensitive and effective.
In carrying our improvements into effect we pivot on a shaft or otherwise suit-
ably mount in the hopper the movable door shutter prongs or equivalent part by
which the regulation of the feed to the hopper is effected, and on this shaft we
secure an lever or other suitably shaped lever connected at one end by links
and levers to one half of a cone or disc friction clutch arranged to slide on a feather
key on a shaft supported outside the hopper. The other friction cone or disc runs
loose on the shaft and is combined with a pulley by which it is driven from the
bottom cene drum shaft or other convenient part. The shaft which carries the
friction cones or discs is geared by a worm and worm wheel or other suitable gearing
with a spiked or other feed roller which it drives when the friction clutch is in
gear to feed forward into the hopper the fibrous material from the trunk or tube;
or instead of gearing the shaft to a feed roller it may be geared to a roller occupy-
ing a corresponding position but carrying the end of a creeper lattice or feed apron.
The knocking off or stop motion rod of the machine, which the hopper feeds, is
also arranged to act, when the machine is stopped, upon one end of the shaped
lever on the regulator shaft and by moving this lever to take the sliding part of the
friction clutch out of gear thereby preventing the feeding of the hopper with raw
material whilst the machine being fed is stopped.

We, Sir BENJAMIN ALFRED DOBSON, Knight, of Dobson and Barlow Limited, Kay
Street Works, Bolton, in the County of Lancaster, Engineer, and JOHN HENRY
PICKUP, of the same address, Foreman, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:
Our invention relates to improvements in regulating mechanism of the type
described in the Specification to Musgrave and Cooper's Patent 11918 of 1894 (assigned
to Dobson and Barlow Limited, of Bolton) for automatically regulating the feed
of fibrous material to hoppers combined with opening machines and certain other
machines employed in the preparation of cotton and other fibrous materials for
spinning, and the object of our improvements is to simplify such mechanism and
render it more sensitive and effective.
In carrying our improvements into effect we pivot on a shaft or otherwise suit-
ably mount in the hopper the movable door shutter prongs or equivalent part by
which the regulation of the feed to the hopper is effected, and on this shaft we
secure an lever or other suitably shaped lever connected at one end by links
and levers to one half of a cone or disc friction clutch arranged to slide on a feather
key on a shaft supported outside the hopper. The other friction cone or dise runs
loose on the shaft and is combined with a pulley by which it is driven from the
bottom cone drum shaft or other convenient part. The shaft which carries the
friction cones or discs is geared by a worm and worm wheel or other suitable gearing
with a spiked or other feed roller which it drives when the friction clutch is in
gear to feed forward into the hopper the fibrous material from the trunk or tube;
or instead of gearing the shaft to a feed roller it may be geared to a roller occupy-
ing a coresponding position but carrying the end of a creeper lattice or feed apron.
The knocking off or stop motion rod of the machine, which the hopper feeds, is
also arranged to act, when the machine is stopped, upon one end of the L shaped
lever on the regulator shaft and by moving this lever to take the sliding part of the
friction clutch out of gear thereby preventing the feeding of the hopper with raw
material whilst the machine being fed is stopped.
The accompanying drawing is a side elevation of a hopper feeder to which our
improvements are applied.
In this view, a designates the casing or frame, 6 the inclined or needle lattice, c
the horizontal or bottom travelling lattice, d the cone drums, e the bottom cone
drum shaft, f the shaft on which the feed regulating prongs or equivalent g are
mounted and h the knocking off or stop motion rod, commonly called the strike
rod, which has an axial movement as usual.
All the foregoing parts are arranged and operate in the ordinary way well under-
stood.
On the shaft f we secure the shaped lever i the longer arm of which is con-
nected by a rod j to one arm of another L shaped lever k fulcrumed at ¹ on the
casing a; the other arm of the lever k engages the boss of a friction disc / fitted
to slide on a feather key in a shaft m on which is mounted loosely a friction
disc n. The shaft m is supported in bearings in two brackets o fixed to the casing a
and it has a worm p secured upon it. A pulley loose upon the shaft m is formed 4
with or secured to the friction disc n and is driven by a belt r from a pulley s

page_text: on the bottom cone drum shaft e. The worm p gears into a worm wheel t on the
axis of which is a pinion t' which drives a spur wheel u on a shaft u.
When applied to a hopper feeder with a trunk v the shaft u carries a spiked
or other feed roller wo or when applied to a lattice feed the shaft u carries the block
or pulley for actuating the creeper lattice x. On the strike rod h we fix an arm h¹
and on the extremity of this arm we pivot a rod y which passes through a guide z
secured to the casing a.
The drawing shows the sliding disc out of gear with the loose friction disc n
and consequently the feed is interrupted as no motion is being transmitted to the
shaft u and feed roller w or to the creeper lattice x as the case may be.
This position arises either when any excess of cotton or other fibrous material
between the inclined lattice & and the regulating prongs 9 moves the latter out-
ward into the position indicated in the drawing, or when the strike rod h is acted
upon by the knocking off or stop motion of the lap end of the machine and thereby
brings the rod y against the shorter arm of the L lever i and moves it into the
position shown in the drawing and so stops the shaft u and interrupts the feed to
the hopper.
When however the supply of cotton or other fibrous material does not exceed
the normal the regulating prongs g by gravity or assisted by a weight, occupy their
usual position and thereby bring the sliding friction disc into gear with the
revolving friction disc n whereby motion is transmitted to the shaft u and feed
roller w or creeper lattice a as the case may be.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is: -
1. The combination with the means herein shown and described for automati-
cally controlling the feed of cotton or other fibrous material to the hopper, of an
extension or connection from the ordinary knocking off or strike rod whereby when
the lap end of the machine is stopped the feed to the hopper is also stopped.
2. The prongs or equivalent feed regulator mounted in the hopper feeder, con-
nections from said regulator to the sliding friction disc, means for driving the other
friction disc from the bottom cone drum shaft, and means for transmitting the
motion to the feed roller or creeper lattice, in combination with the rod y connected
to the knock off or strike rod h substantially as and for the purposes herein set
forth.
