PROVISIONAL SPECIFICATION.
Improvements in the Mounting of Thread Guides of Spinning and
Doubling Machines.
We EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY
Machine Makers, Globe Works Castleton, Manchester, do hereby declare the
nature of this invention to be as follows:-
This improvement consists in mounting the thread guides on a round shaft, and in the
arrangements for mounting this shaft in position on the roller beam. In carrying
out our invention we form a recess in the front part of the beam into which we
place a round shaft, the hinges for the thread guides being fastened thereto.
We
arrange the
groove or recess in the beam so as to allow sufficient rotation to the
shaft for the purpose of doffing. The shaft is prevented from lifting out of the
recess by caps, & stops are provided to adjust the thread guides to their working
position.
The two opposite sides of the machine are connected by wheels or levers so as to
be worked simultaneously.
To assist in securing the hinges to the shaft we make flats or grooves and
counter-sink the screw holes in the shaft, and form the hinges to fit these counter-
sunk holes.

COMPLETE SPECIFICATION.
Improvements in the Mounting of Thread Guides of Spinning and
Doubling Machines.
We, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY,
of Globe Works, Castleton, near Manchester, in the County of Lancaster, Machine
Makers, 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 :-
The object of our invention is to facilitate the raising of the thread guides from
the position they occupy when the machine is at work, so as to permit the bobbins
to be easily doffed when a change is required; and our improvements consist in
mounting the thread guides onto a round shaft, and also in arrangements for
mounting this shaft in position on the roller beam.
In carrying out our invention, we form a longitudinal recess or groove in the front
part of the roller beam, into which groove we insert a round shaft. The flaps
carrying the thread guides are secured to the said shaft by a suitable form of hinge,
and the shaft carrying the flaps and thread guides, is made to partially rotate by
operating a hand lever, the motion of which is transmitted to the opposite side of the
machine by a suitable arrangement of levers and wheels for the purpose of raising
the thread guides on both sides of the machine simultaneously.
In order that our invention may be better understood, we will make reference to
the accompanying sheet of drawings illustrative thereof, wherein Fig. 1 is cross-
section of such portions of a spinning and doubling machine as is necessary to shew
the application of our improvements; Fig. 2 is end view of Fig. 1; Fig. 3 is plan
view of same, and Fig. 4 is an enlarged detail of the round shaft, shewing how it is

page_text: supported and kept in position. A represents the roller beam, in the front edge of
which, we form a longitudinal groove or recess for receiving the round shaft B,
which is made secure in the recess by suitable caps C connected by set screws to
the front of the roller beam A.
The flaps D which carry the thread guides E, are secured to the shaft B by
a suitable form of hinge, of which one is shewn at N in Fig. 4. When the machine
is at work the flaps and thread guides occupy the positions shewn in full line in
Fig. 1 immediately over the bobbin F, but for the purpose of doffing, we oscillate
the shaft B, so as to raise the flaps and thread guides into the positions shewn in
dotted lines in Fig. 1, whereby the hobbins are free to be doffed.
The method of oscillating the shaft B is as follows:-We mount on the said
shaft B, cranks G, on the lower end of which, is a connecting rod H made
adjustable in length by nuts O the opposite end of such rod fitting onto a stud I
projecting from the back of the bevel wheel J, therefore, when it is necessary to
doff the bobbins, the operative moves the hand lever K on the end of the shaft L,
in doing which, the bevel wheel M at the end thereof actuates the bevel wheel,
the motion of which wheel, together with the stud I moves the connecting rod F,
whereby the crank G is placed into the position shewn in dotted lines, and the flaps
and thread guides raised accordingly. The reverse motion of the hand lever K
places the thread guides back into their working position again.
The bevel wheel J carries two studs I and I', the latter being employed to
operate a second connecting rod H¹ for raising the thread guides at the opposite
side of the machine, and by the employment of means for adjusting the length of
the connecting rods H and H¹ the working position of the thread guides can be
varied.
As indicated near the star in Fig. 1 the two rods H and H³ come into contact
with each other or overlap at the end of their stroke in both directions, whereby
they become locked and act as stops to any further movement.
In the foregoing description it will be seen that the thread guides on both sides
of the machine can all be adjusted and simultaneously and readily raised up and
down for the purpose specified, and as the round shaft B fits into the recess all
along the front of the beam A a neat joint is made and prevents the accumulation
of dirt and loose fibres.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:—
Firstly. Mounting the shaft which carries the thread guides in a groove formed
in the roller beam, as described and shewn in the drawings.
Secondly. The general arrangement and combination of parts, substantially as
herein shewn and described for adjusting and moving the thread guides to permit
the doffing of the bobbins.
