Improvements in Spindles and Parts Operating therewith in Gill,
Drawing, Reducing, and Roving Boxes for the Treatment of
Fibres previous to Spinning.
We PRINCE SMITH the younger of the firm of Prince Smith & Son of Burlington
Shed Keighley, in the County of York, Machine Maker, and JOSEPH LUND of the same
place, Mechanic, do hereby declare the nature of this invention to be as follows:-
These improvements have reference to the spindles and their adjacent parts employed
in Gills Drawing Reducing and Roving Boxes used previously to spinning Wool
Worsted Silk Cotton or other fibrous substances.
The object of the invention is to obtain a steadier action in running with increased
speed and greater facility in effecting the doffing of the full bobbins and the replace-
ment thereof by empty ones.
In order to the readier comprehension of our invention we will without confining
ourselves to the precise detailed arrangement describe the same as applied to a certain
form of parts as used in the manipulation of wool or other fibre in Gill drawing
Reducing or Roving boxes or the like.
Supposing the roving to have been brought by suitable carriers and to have reached
the front or low roller it is then supplied to the spindle and flyer, through the upper
part of the former and thence to one wing of the flyer, through an eye or one of eyes
formed in a cross piece at the upper part or shoulder of the flyer, and thence to and
through a twizzle at the lower end of one wing and thence to be wound on to a bobbin
on the spindle.
The top bearing in which the spindle revolves and is supported is formed recessed
horizontally throughout its thickness and is further recessed of still larger diameter
for a certain depth. This lower part of the bearing of smaller diameter of recession
is for the purpose of admitting a part of the spindle formed of a smaller diameter and
the wider recess to admit the upper enlarged part or head of that spindle by the
حيم

page_text: spindle being passed into the narrow notch and then dropping a short distance
therein to bring the upper enlargement into the wider recess.
In operation when the minder doffs the bobbin from the spindle she lifts the spindle
up so as the part of the spindle comes out of the recess and then draws the spindle
out of the groove the spindle neck being long enough to admit of its being raised high
enough to clear the recess in the upper bearing and she slips the bobbin off in the
usual way and effects its replacement.

Improvements in Spindles and Parts Operating therewith in Gill,
Drawing, Reducing, and Roving Boxes for the Treatment of
Fibres previous to Spinning.
We PRINCE SMITH the Younger of the firm of Prince Smith & Son of Burlington
Shed Keighley in the County of York Machine Maker, and JOSEPH LUND of the same
place Mechanic, 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 :—
These improvements have reference to the spindles and their adjacent parts employed
in Gills Drawing Reducing and Roving Boxes used previously to spinning wool
worsted silk cotton or other fibrous substances.
The object of the invention is to obtain a steadier action in running with increased
speed and greater facility in effecting the doffings of the full bobbins and the replace-
ment thereof by empty ones.
In order to the readier comprehension of our invention we will without confining
ourselves to the precise detailed arrangement and with the aid of the accompanying
drawings describe the same as applied to a certain form of parts as used in the
manipulation of wool or other fibre in Gill Drawing Reducing or Roving Boxes or
the like.
Figure 1 is a front view and Figure 2 an edge view with parts of the framing and
supports in section of so much of a drawing frame as will facilitate explanation of our
invention.
A represents the Low Front Roller, B the Spindle top, C the bearing in which the
spindle top revolves, D the Spindle and Flyer, and E¹ the step or centre in which the
foot of spindle rests.
In the Drawing the bearing for spindle top to revolve in is shewn recessed as at B
and the top part of the spindle E is turned to fit that recess.
The lower part of the bearing is bored out a smaller diameter to fit the smaller part
or neck of the spindle top as shewn at E then a groove is cut right through the
bearing as shewn at e Figure 3 so as to admit of the spindle being fitted into its
place.
The operation of the parts is as follows:-
Supposing the roving 1 to have been brought by suitable carriers and to have
reached the front or low roller A it is then supplied to the spindle and flyer D through
the upper part of the former 2 and thence to one wing 3 of the flyer through an eye
or one of eyes 4 formed in a cross piece 5 at the upper part or shoulder of the flyer
and thence to and through a twizzle 6 at the lower end of one wing and thence to be
wound on to a bobbin on the spindle not shown.
The top bearing C. in which the spindle D revolves and is supported is formed
recessed horizontally throughout its thickness as at 7 (see plan of this detail Figure 3)
and is further recessed of still larger diameter for a certain depth at 8. The lower

page_text: part of the bearing of smaller diameter of recession is for the purpose of admitting the
part of the spindle formed of, a smaller diameter, and the wider recess to admit
the upper enlarged part or head of that spindle by the spindle being passed into
the narrow notch 7 and then dropping a short distance therein 'to bring the upper
enlargment into the wider recess 8.
When the doffing of the bobbin from the spindle is effected the attendant lifts the
spindle D up so as the top part of that spindle comes out of the recess at B and then
the spindle D is drawn out of the groove, the spindle neck being long enough to
admit of its being raised high enough to clear the recess as shewn at E and then the
bobbin is slipped off in the usual way.
By means of our invention a steadier form of running and a quicker and greater
facility in doffing full bobbins and replacing the empty bobbins is attained.
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 and use of spindles and adjacent parts of apparatus for Gills,
Drawing Reducing and Roving Boxes in the treatment of fibres previous to spinning
substantially as and for the purpose set forth.
