Improvements in or connected with the Fastening or Attaching of
the Perforated Spindles or Skewers in Cop Dyeing Machines.
I, ROBERT SHAW, of Droylsden Road, Newton Heath, Manchester, in the
County of Lancaster, Cashier, do hereby declare the nature of this invention to be
as follows:
This invention relates to the hollow perforated spindles or skewers which carry the
cops and through which the liquor is forced in cop dyeing machines. Hitherto these
skewers have been secured in position in the plate upon which they are carried by
means of a screw or bayonet joint or by a plate placed on their top or upper ends,
these and other methods adopted are objectionable as being difficult to adjust and
remove or as being liable to damage the skewers.
This invention is designed to provide more efficient means of fastening or
attaching the skewers to the plates and while providing a tight joint between the
two the skewers will be easily placed in position and removed.
The plates which carry the skewers are provided with a number of sockets to
receive the ends of the skewers. These sockets are formed for the greater part
of their length of a diameter larger than the skewer which they are to receive the
lower end being of the same diameter as the skewer. The upper end of the socket
is formed of a size to receive the head of a rubber washer and the flange of the
skewer. A tapered rubber washer is formed to fit into the socket of a contour
corresponding to that of the socket but tapering in length so that at its lower end
when fitted into place a space or cavity is left between the socket and the back of
the washer.
A. flanged ring or washer is screwed down on top of the head of the rubber
washer. This ring or washer serves to hold both the washer and the skewer in
position. The top of this washer is formed so that the flange of the skewer can
pass in and be turned round below its upper edge.
The skewer is formed with a flange of oblong shape which can be passed down
through the opening of corresponding shape in the metal washer and on being
turned to one side or the other is secured in position. This flange or the underside
of the washer may be tapered or inclined in either direction and the turning of the
skewer to secure it will tend to press it down tightly upon the top of the rubber
washer. The shape of the flange may be oblong, oval, angular or of other irregular
contour and the hole in the washer made to correspond therewith or it may simply
have one two or more projecting pins to fit into slots.
It will be obvious that instead of having a loose washer to screw into each socket
above the rubber washer, a plate with a number of projecting nipples or
sockets may be used to fit down into the sockets on the first mentioned plate.
To secure the spindles or skewers in position the tapered rubber washers are
placed in position in the sockets, the metal washer screwed down upon the head
thereof, the end of the spindle inserted into the rubber and the flange passed down
into the opening in the top of the metal washer and turned round part of a
revolution to secure it. The cavity behind the tapered washer allows the liquor
under pressure to pass in between the washer and the socket and presses the rubber
more tightly against the end of the spindle. The spindle can be very easily
removed and replaced without disturbing the washers in the socket.

Improvements in or connected with the Fastening or Attaching of
the Perforated Spindles or Skewers in Cop Dyeing Machines.
ROBERT SHAW, of Highfield Road, Seedley, near Manchester, in the County of
Lancaster, Cashier, late of Droylsden Road, Newton Heath, Manchester, 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 the hollow perforated spindles or skewers which carry
the cops and through which the liquor is forced in cop dyeing machines. Hitherto
these skewers have been secured in position in the plate upon which they are
carried by means of a screw or bayonet joint or by a plate placed on their top or
upper ends these and other methods adopted are objectionable as being difficult to
adjust and remove or as being liable to damage the skewers.
This invention is designed to provide more efficient means of fastening or
attaching the skewers to the plates and while providing a tight joint between the
two the skewers will be easily placed in position and removed.
It will be fully described with reference to the accompanying drawings.
Fig. 1. Sectional elevation.
Fig. 2. Front elevation.
Fig. 3. Plan.
Fig. 4. Perspective view of bottom end of cop tube.
The plates E which carry the skewers are provided with a number of sockets e
to receive the ends of the skewers H. These sockets are formed for the greater
part of their length of a diameter larger than the skewer which they are to receive
the lower end being of the same diameter as the skewer. The upper end of the
socket is formed of a size to receive the head of a rubber washer G and the flange h
of the skewer H. A rubber washer G is formed to fit into the socket e of a
contour corresponding to that of the socket but preferably tapering in length so
that at its lower end when fitted into place a space or cavity is left between the socket
and the back of the washer.
A flanged metallic ring or washer g is screwed down on top of the head of the
rubber washer G. This ring or washer y serves to hold both the rubber washer G
and the skewer H in position. The top of this washer g is formed so that the
flange of the skewer H can pass in and be turned round below its upper edge.
The skewer is formed with a flange h of oblong shape which can be passed down
through the opening gl of corresponding shape in the metal washer g and on being
turned to one side or the other is secured in position. This flange h or the under
side of the metallic washer g may be tapered or inclined in either direction and the
turning of the skewer H to secure it will tend to press it down tightly upon the top
of the rubber washer G. The shape of the flange may be oblong, oval, angular
or of other irregular contour and the hole in the washer 9 made to correspond
therewith or it may simply have one, two or more projecting pins to fit into slots.
On its upper side the flange is provided with two wings or projections
which a grip can be obtained to turn it tightly into position.

by
It will be obvious that instead of having a loose washer 9 to screw into each
socket e above the rubber washer G a plate with a number of projecting nipples or
sockets may be used to fit down into the sockets e on the plate E. And also that
the rubber washer G may be made in the form of a flat ring and the socket e made
to fit the spindle H for its whole length.
To secure the spindles or skewers H in position the rubber washers Gare placed
in position in the socket, the metal washer g screwed down upon the head thereof
the end of the spindle inserted into the rubber washer and the flange h passed down
into the opening g' in the top of the metal washer g and turned round part of a

page_text: revolution to secure it.
When the rubber washer G is made tapered the cavity
behind the tapered part allows the liquor under pressure to pass in between the washer
and the socket and presses the rubber more tightly against the end of the spindle.
The spindle can be very easily removed and replaced without disturbing the washers
in the socket.
Instead of securing the rubber washer G and skewer H in position by screwing
the metal washer g into the plate E the metal washer can be secured in position by
screws such as gl screwed into the plate beside it.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The fastening of the cop skewer H into the plate E by means of the metallic
washer such as g affixed to the plate and the flange attached to the skewer which
is passed down below the washer 9 substantially as described.
g
2. The combination with the cop plate E provided with sockets e to receive the
ends of the skewers of the rubber washer G the metallic washer 7 affixed to the
plate and provided with openings gl and the flange h on the skewer H provided
with projections to fit into the openings g' and wings by which to rotate it
substantially as described.
