PROVISIONAL SPECIFICATION
An Improved Portable Tray or Cage for Holding Bobbins or Pirns
Carrying Yarn for Weaving.
ROBERT HENRY READE, Merchant, WILLIAM KENNEDY, Factory Manager, and
MATHEW SHAW, Factory Foreman, all of York Street Mills Belfast, Ireland do
hereby declare the nature of this invention to be as follows:-
This invention consists of an improved tray or cage for holding the bobbins or
pirns to be woven and it will be understood from the following description :-
The pins in the ordinary tray or cage at present in use, are formed either by pro-
jections of round wire through the bottom of the cages in Duplex form & kept in
their places by being soldered on the under side of the bottom of the cage, or they
are formed by a strip of sectoral sectioned (half round) wire running from one side
of the tray to the other, the pins being formed from this wire by projecting through
the bottom at regular or suitable intervals and looped or turned back when they are
the required height, the whole being soldered to the under side of the bottom of the
cage.
These pins are in the first instance parallel and in the latter larger at the point than
at the base.
We propose to form the pins in our invention by soldering the half round wire on
the upper side of the bottom of the cage, and this wire running along the upper side
of the bottom will form a ridge, which will be made the proper size to fit into the
groove of the head of the pirn or bobbin, and thus prevent the pirn or bobbin moving
or turning which will be an improvement on the ordinary tray or cage.
We also propose to carry out the same object by corrugating the bottom of the
tray and thus forming ridges of the required height and breadth towards the inside
so that they will fit the
of the pirn.
groove
We also propose making the pins wider or larger at the base than at the top, so
that they will naturally fit the spindle hole of the pirn or bobbin.

COMPLETE SPECIFICATION.
An Improved Portable Tray or Cage for Holding Bobbins or Pirns
Carrying Yarn for Weaving.
ROBERT HENRY READE, Merchant WILLIAM KENNEDY, Factory Manager and
MATHEW SHAW, Factory Foreman, all of York Street Mills, Belfast, Ireland, 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 consists of an improved tray or cage for holding the bobbins or
pirns carrying yarns for weaving, and will be understood from the following descrip-
tion, reference being had to the drawings herewith in which the same letters and
figures of reference always apply to the same or like parts.
Figures 1 and 2 shew the form of portable cage for holding the bobbins and it is
necessary that there should be a separate pin for each bobbin or piru.
A strip of sectoral-sectioned (half round) wire is attached to the upper side of the
bottom of the tray and runs across the tray from side to side (a to B Fig. 1) and the
pins or projections (e) are formed at suitable distances, by raising and folding this half
round wire (Fig. 2).

page_text: This pin is wider or larger at the base than at the top and thus forms a cone, and
the whole strip forms a ridge and pin alternately across the cage.
These strips of wire are made of a certain size so that they will fit into the groove
on the lead of the pirn or bobbin.
When the pirn or bobbin is placed on the pin, the vibration caused by a loom in
motion naturally makes the pirn or bobbin fall into one position on the ridge where
it cannot turn round.
Fig. 3 shows a ridge formed by corrugating the bottom of the tray and represents
a section from a to B Fig. 1.
The pins are formed by the half round wire running in the groove under this ridge
and projecting through the bottom at suitable intervals which suits the same purpose
viz. to keep the pirns from turning on the pins of the trays when vibrated by the
motion of the loom.
Fig. 4 shows a sectional view of the ridges, in the tray with the corrugated bottom
from e to D.
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 :-
The construction of portable cages with ridges and projections or pins of the shape
described for the purpose of preventing the pirns from turning round on the pins
when the tray is vibrated by a loom in motion, thus avoiding waste of yarn.
