PROVISIONAL SPECIFICATION.,
Improvements in, Loom Shuttle Eye Machines.
We HENRY ROBINSON HALLEN Engineer and ALFRED ADAMS Engineer both
of Wellington Street Works, Burslem in the County of Stafford, do hereby declare
the nature of this invention to be as follows:-
In the manufacture of a shuttle for weaving looms it is customary to insert in it
an eye consisting of a bush formed of a tube of porcelain or such like hard
and smooth substance, through which the weft is led from the shuttle spool or
bobbin.
Now this invention for improvements in loom shuttle eye machines has for its
object to produce such bushes or eyes with greater accuracy and dispatch than
has hitherto been attained with the methods ordinarily employed, and consists
in improved means for cutting the clay to the desired lengths to form the said
eyes.
In a machine constructed according to this invention two cylinders whose axes
are parallel to one another are mounted in suitable bearings on a table, and rotated
by suitable gearing either, by hand, or otherwise. One cylinder is built up of
alternate washers or distance ferrules and circular knives, threaded on a central
mandril, the pitch of the said knives being varied by the lengths of the washers to
suit the lengths of the shuttle eyes, while the remaining cylinder is plain, and
provided with adjustable bearings to allow of the distance between the axes of the
two cylinders being varied to suit the diameter of the shuttle eyes.
The clay is first rolled out into a length of suitable diameter and is then thrown
by a movable table between the rotating rollers and cut into the required lengths
by the rotating knives, whence it is automatically removed by spoons actuated by
suitable mechanism.

COMPLETE SPECIFICATION.
Improvements in Loom Shuttle Eye Machines.
We HENRY ROBINSON HALLEN, Engineer, and ALFRED ADAMS, Engineer,
both of Wellington Street Works, Burslem, in the County of Stafford, 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 :-
In the manufacture of a shuttle for weaving looms it is customary to insert in
it an eye consisting of a bush formed of a tube of porcelain or such like hard
and smooth substance through which the weft is led from the shuttle spool or
bobbin,
Now this invention for improvements in loom shuttle eye machines has for its
object to produce such bushes or eyes with greater accuracy and dispatch than
has hitherto been attained with the methods ordinarily employed, and consists
in- improved means for cutting the clay to the desired lengths to form the said
eyes.
In a machine constructed according to this invention two cylinders whose axes
are parallel to one another are mounted in suitable bearings on a table, and rotated
by suitable gearing either, by hand or otherwise. One cylinder is built up of

page_text: alternate washers or distance ferrules and-circular knives, threaded on a central
mandril, the pitch of the said knives being varied by the lengths of the washers to
suit the lengths of the shuttle eyes, while the remaining cylinder is plain and
provided with adjustable bearings to allow of the distance between the axes of the
two cylinders being varied to suit the diameter. of, the shuttle eyes.
The clay is first rolled out into a length of suitable diameter and is then placed
by hand on a removable table and is rolled between tlie rotating rollers and cut into
the required lengths by the rotating knives, whence it is automatically removed by
spoons actuated by suitable mechanism when required. .
In the accompanying two sheets of illustrative drawings,
Fig. 1. represents a vertical section of the upper part of a machine constructed
according to this invention..
Fig. 2. is a plan and.
Fig. 3. is a side elevation of the same.
Two cylinders a, whose axes are parallel work in suitable bearings, d'secured
to a frame e on a suitable stand and driven through the belt pulleys, h. The
cylinder bis built up of, ferrules and circular knives or discs threaded alternately.
on a central spindle m so that the pitch of the knives I may be varied by changing
the ferrules i. The distance between the cylinders a, may be varied to suit
different sizes of shuttle eyes by means of the adjusting screws. in the brackets.o.
A spindle is provided, carrying spoons corresponding to the knives and
capable of being revolved by the handler to remove any shuttle. eyes from the
cylinder which may stick to it after being cnt. A bars rests upon the brackets >>
and is caused: when required to press upon the surface of. the cylinder a by means
of the lever to remove any clay therefrom that may be found to adhere to it at
any time. The rolled rods of clay are placed upon the table and passed on to the
cutter cylinder whence it is carried between, the two cylinders and cut into the-
required; 1.ngths which fall into the shoot and are conveyed to, the .outside of
the machine, as clearly shown.
'
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. Inia machine for the manufacture of loom shuttle eyes the employment of a
cutter cylinder built up of ferrules and circular knives alternately and rotating in
conjunction with a second cylinder between which said cylinders the eyes are
formed into suitable lengths substantially as described.
2. The arrangement, and construction of machines for the manufacture of loom
shuttle eyes substantially as described with reference to the drawings.
