PROVISIONAL SPECIFICATION.
An Improved Shuttle for Looms.
We, SAMUEL AUSTIN of No. 73 Fenney Street, Bury New Road, Manchester,
Wire Weaver Foreman, and WILLIAM HARGREAVES of 25 Wellington Street
East, Higher Broughton, Manchester, Manager of Wire Works, do hereby declare
the nature of this invention to be as follows:-
This invention relates to an improved construction of shuttle wherein the spool
is arranged with its axis vertically or transversely instead of horizontally or
lengthwise. For this purpose the shuttle body, which is preferably of metal or of
a combination of metal and wood, is formed with a central rectangular recess for
receiving a correspondingly shaped friction spool box, containing a spool with the
required weft. The spool is pivotted on a vertical loose pin suitably held in the
box and the spool is made to revolve with friction in the box by fitting with its
rims in circular grooves formed in the box.
The spool box is divided into two halves hinged together so as to be capable of
being opened out to receive the spool and loose pin the two halves are secured
together by a spring catch in such manner as to produce the required amount of
friction between its grooves and the rims of the spool to prevent this from running
too fast.
The spool being thus confined in the said box, the free end of the weft is effectually
prevented from running off the spool and lapping round the centre pin.

COMPLETE SPECIFICATION.
An Improved Shuttle for Looms.
We, SAMUEL AUSTIN, Wire Weavers Foreman of No. 73 Fenney Street, Bury
New Road Manchester and WILLIAM HARGREAVES of 25 Wellington Street
East, Higher Broughton, Manchester, Manager of Wire Works, 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 :-
This invention relates to an improved construction of shuttle wherein the spool
is arranged with its axis vertically or transversely instead of horizontally or
lengthwise.
For this purpose the shuttle body, which is preferably of metal or of a combina-
tion of metal and wood, is formed with a central rectangular recess for receiving a
correspondingly shaped friction spool box, containing a spool with the required
weft. The spool is pivotted on a loose pin suitably held in the box and the spool
is made to revolve with friction in the box by fitting with its rims in circular
grooves formed in the box.
The spool box is divided into two halves hinged together so as to be capable of
being opened out to receive the spool and loose pin; the two halves are secured
together by a spring catch in such manner as to produce the required amount of
friction between its grooves and the rims of the spool to prevent this from running
too fast. The spool being thus confined in the said box, the free end of the weft
is effectually prevented from running off the spool and lapping round the centre
pin or the body of the shuttle.

page_text: Fig. 1 of the accompanying drawings shews a longitudinal section of the improved
shuttle, Fig. 2 shews a plan, Fig. 3 a sectional plan of the spool and shuttle box
detached, Fig. 4a left hand end view of the same, Fig. 5 a right hand end view,
and Fig. 6 an inside view of the plate B.
The shuttle body A, which is here shewn as being made partly of wood and
partly of metal, has fitted into its rectangular recess a metal shuttle box composed
of two end plates B B, that are secured to the end faces of the recess by screws C,
and two divided side plates D D', D D', of which the two lower parts D D are
secured to the plates B B, by means of pins E E passing through grooves B
formed in the plates B, as shewn, while the two upper parts D' D' are attached at
one end to the parts D D by pivotted links F F, so that the parts D¹ D' can be
turned up on such pivotted connection. At the other end the two parts D' D' are
connected together by a cross bar G. The parts D D¹ have firstly semicircular
notches at their meeting surfaces which, when closed, embrace the ends of the
loose pin upon which is fitted loose the spool I. The inner faces of the
parts D D are furthermore recessed to receive the circular flanges or rims of
the spool, the recesses being made to fit with sufficient friction against the
periphery of the flanges I to prevent the spool from running too fast. The pin H
and spool having been placed in position when the parts D¹ D' of the side plates
are open, these are closed down and are secured in that position by a spring catch.),
that catches over the bar G, and which can be withdrawn by the looped
trigger K.
It will be seen that as the flanges I of the spool and the ends of the pin H are
entirely covered in by the side plates D D₁, the thread or wire on the spool
cannot possibly get lapped or entangled round those parts nor escape outside
the box.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
:-
1. In shuttles for looms, a spool box consisting of divided side plates such
as D D pivotted together so as to open out and receive between them the loose
pin of the spool, while the flanges or rims of the spool fit with a certain amount
of friction into recesses in the said plates whereby any lapping of the thread or
wire round such rims or pin is prevented, substantially as described.
2. In spool boxes for shuttles the combination of the grooved end plates B,
divided pivotted side plates D D' connecting links F and cross bar G, catch J
and trigger all operating substantially as described.
