COMPLETE SPECIFICATION.
Improvements in and relating to Condenser Bobbins, and Beam or
other like Rollers.
We, HENRY SOUTHWELL and JAMES GRANDIDJE, both of Hudson Street Saw
Mills, Rochdale, in the County of Lancaster, Bobbin Manufacturers, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
Our invention relates to improvements in beam roller or other similar bobbins.
The principal features and objects of our invention being to dispense with the
rod or spindle which as now generally constructed passes through the bobbin
also to provide a means whereby the flanges or ends may be firmly and securely
held and maintained in position so that the said ends or peripheries thereof may
always be maintained in a true or concentric position with relation to the axis
of the bobbin or shaft ends.
In practice it is found that the holes or apertures in the ends or flanges which
are usually made of metal-and the central hole of which encircles the spindle
or rod the said hole becomes enlarged due to the cause of wear and tear or usage
by the operatives throwing the bobbins to the floor, the flanges sustaining the
impacts consequently in such events the holes of the flanges are caused to become
enlarged at the parts surrounding the rod thus the said flanges turn round loosely
and eccentrically, with relation to the bobbin which is objectionable when the said
bobbins are in use.
In order to clearly comprehend the invention we hereunto annex a sheet of
drawings illustrating the same.
Fig. 1 is an elevation in section shewing the application of my invention to a
condenser bobbin or beam roller which fig. shews one end of such a bobbin.
Fig. 2 is a front view of Fig. 1.
Fig. 3 is a view shewing the ferrule or short tube and the winged piece or
socket in position.
Fig. 4 is a view of the ferrule removed separately from the bobbin.
Fig. 5 is a view of the socket piece removed separately from the bobbin end.
We provide on the end of the bobbin a, a metal ferrule or short tube, b. We
insert into the material of the bobbin also at its end a socket piece c, which is
provided with wing pieces c¹ and a central socket piece c² recessed and provided
with a screw thread.
We employ a circular piece or cap d, having a screw threaded shank, e, which
passes into or is adapted to screw into the recess ³. The cap is also provided
with a shank or spindle f of any suitable length which forms the bearing part
of the bobbin end. The said cap, and the beam end or flanges are provided
with holes h, through which are passed wood screws, i, which when the end is
in position with relation to the bobbin see Fig. 1, the end is firmly held and main-
tained in a true concentric position with relation to bobbin and prevented from
turning about its axis which is also aided by the cap d being secured in proximity
thereto by being screwed within the socket c³. We have thus shewn an arrange-
ment for dispensing with the usual rod also the secure clamping of the flange

page_text: obviating the same from working loose on the central spindle consequently obvi-
ating the eccentric movements of the flange or end thereon. According to our
arrangement a wood or metal flange may be readily adjusted on or secured to the
bobbin end when required for the purpose of replacing a damaged flange.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In combination the ferrule, b, socket c, cap d, screws, i, and flange g as and
for the purposes set forth.
2. In combination ferrule b, socket c, cap 7, and screws i, as and for the
purposes set forth.
3. In combination cap, d, having apertures h shanks e and f, and socket c, as
and for the purposes set forth.
4. In combination socket c, and ferrule b as and for the purposes set forth.
