PROVISIONAL SPECIFICATION.
Improvements in Thread Spooling Machines.
We JAMES MCILRAITH of Prospect Villas, Blackley, in the County of
Lancaster, Millwright, EDMUND NORBURY BAINES of 30 Park Avenue,
Longsight, Manchester, Engineer, and WILLIAM AYRTON of Gorebro k
Ironworks, Longsight, Manchester, Engineer, do hereby declare the nature of
this invention to be as follows :-
•
Our said invention relates to improvements in the machines for winding thread
on bobbins or spools known as Conant machines, such as are described in the
Specification of Patent No. 2452 of A.D. 1864 and has for its object novel means
for driving the spindles of such machines.
In employing such machines it is usual to assemble a number of spindles on a
common frame and to drive the spindles by means of a belt passing round pulleys
on countershafts under the machine. Such countershafts are parallel to the
spindles and are driven by a belt passing over and under the successive
countershafts.
:
According to our said invention the spindles are driven by one or more
longitudinal back shafts placed at right angles to the spindles. By means of bevel
or other gearing or belts the rotation of such lougitudinal shafts is transmitted to
a sleeve or bush mounted on each spindle. A sliding clutch is mounted on each
spindle so that when in gear with the sleeve the spindle is driven. The clutch is Bo
constructed that the,mechanism which puts it out of gear aeta at the same time.as
a brake and thus quickly arrests the rotation of the spindle..

Improvements in Thread Spooling Machines.

Lancaster, Millwright, EDMUND NORBURY BAINES of 30 Park Avenue,

Ironworks, Longsight, Manchester, Engineer, 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 :-
.
Our said invention relates to improvements in the machines for winding thread
on bobbins or spools known as Conant machines such as are described in the
Specification of Patent No. 2452 of A.D. 1864 and has for its object novel means
for driving the spindles of such machines.
'
In order to more clearly set forth our said invention we will describe the same
with reference to the accompanying drawings.

page_text: 1
Figs. 2 and 4 are corresponding views showing bevel tooth driving.
Figs. 5 and 6 are corresponding views showing skew spur or worm driving.
Fig. 7 is an elevation partly in section of a spindle with its clutch mechanism.
In employing such machines it has beretofore been usual to assemble a number of
spindles or "heads on a common frame and to drive them by means of a belt
passing round pulleys on countershafts under the machine. Such countershafts are
parallel to the spindles and are driven by a belt passing over and under the
successive pulleys.
"
According to our said invention the spindles are driven by one or more
longitudinal back shafts placed at right angles to the spindles and by means of
bevil or other gearing or belts or the like flexible driving media the rotation of
the longitudinal shaft is transmitted to a sleeve or bush mounted on each spindle.
Figs. 1 to 6 inclusive illustrate this part of our said invention.
In all these figures the letters a indicate the centre lines of the spindles 6 is the
longitudinal driving shaft which is at right angles to the spindles a and is driven
by the belt pulleys c.
According to the arrangement shown in Figures 1 and 2 the rotation of the
longitudinal shaft b is transmitted to the spindle a by means of flexible driving
media such as belts or cords d passing round pulleys on the shaft b and corre
sponding pulleys on the sleeves of the spindles. Suitable intermediate guide
pulleys 9 are provided for guiding the belt or cord.
According to the arrangement shown in Figs. 3 and 4 the rotation of the shaft b
is transmitted to the spindle sleeves by means of bevel wheels and i. In some
modification of this arrangement we may use skew bevel instead of ordinary bevel
wheels.
According to the arrangement shown in Figs. 5 and 6 the rotation of the shaft b
is communicated to the spindle sleeves through skew spur or worm wheels. On
the spindle a (Fig. 7) we mount a loose sleeve m carrying at one end the wheel or
pulley which derives motion as hereinbefore described from the shaft b. The
other end of the sleeve m is formed at m' so as to constitute part of a friction
clutch. The other part of the friction clutch n is free to slide longitudinally on
the spindle a but being slotted at n' to receive a key or feather on the
spindle a any rotation of the part n communicates itself to the spindle.
'
A spiral spring o bearing at one end against a collar o' and at the other end
against the face ² continually tends to press the sliding part n of the clutch
into engagement with the corresponding part of the clutch formed on the
sleeve m.
The slide bar p is used in Conant winding machines as at present constructed.
Its function and the mechanism for operating it is described under the letter C¹ on
page 9 of Conant's Specification hereinbefore cited. We make no claim to this
slide bar. (or to the means for operating it) in and of itself.
On the said slide bar p we mount a bracket r carrying at its upper end a fork
faced at with leather or other suitable material so as to form a brake surface.
The slide bar p being released is shot in the direction of the arrow by the
spring p¹ when the bobbin is full and we so set the bracket r on the shaft p as that
when the shaft p shoots forward the fork shall bear against the collar n and
withdraw the part n from engagement with the part m of the sleeve m. thus
disconnecting the spindle from the source whence it derives its rotation. At the
same time the part acts as a brake to overcome the momentum of the rotating
spindle and so to bring it to rest.
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.-
1. The herein before described construction and arrangement of the driving
mechanism of a thread winding machine substantially as set forth and shown..

set forth and shown.
