We, WALTER MCGEE and DAVID MCGEE both of the firm of Walter McGee & Son,
Albion Works, Paisley, Engineers and Machinists do hereby declare the nature of
this invention to be as follows:-
--
Our invention which relates to thread spooling machinery, has especial reference
to improvements in connection with the shaping wheels or shapers which serve to
regulate the traverse of the thread guide so as to gradually increase the width of the
layers of thread wound upon the spool in order to cover the conical portions evenly
with the cylindrical part thereof.
In lieu of the usual shaping wheels or racks which are provided with teeth gradually
increasing in width and in using which a separate wheel or rack is required for each
different size or shape of spool to be filled, we employ two toothed pinions which when
placed end to end together make up the minimum width of traverse of the thread
guide, and which are expanded automatically as the spooling proceeds in order to
adapt them to the gradually increasing width of traverse required for filling the wider
portions of the spools extending over the conical sides thereof. The shaping pinions
or wheels are fitted upon a shaft which is turned back by means of a weight or
spring as each tooth is in turn released by the travelling pins or fingers which are
traversed by a right and left threaded screw spindle and operate the thread guide
in the ordinary way; and the wheels are so keyed or secured on the shaft
that either or both may slide thereon and be moved to separate or expand them.
The expanding movement may be effected in various ways, one convenient plan
being to form collars on the ends of the wheels into which are fitted levers
operated by inclines or wedges or cams from the shaping wheel shaft, or a shaft
driven thereby, or an incline, wedge or cam may be fitted to act directly or through
other mechanism on the wheels to separate or expand them gradually, as the shaft
turns and a fresh tooth on the wheels is presented to the travelling pins or fingers.
before mentioned to regulate the traverse of the thread guide.

page_text: Our invention also comprises an improved stop motion or mechanism for stopping
the operation of the shaper when the spool becomes filled the said stop motion
consisting of a lever arm adjustably secured upon the cam shaft or a shaft geared
from the shaping wheel shaft and arranged to act directly on the lever of the usual
mechanism for throwing the shaping machinery out of gear the said lever arm being
adjusted to come into operation upon the completion of the movement of the
shaping wheels.

We, WALTER MCGEE and DAVID MUGEE both of the firm of Walter McGee & Son,
Albion Works, Paisley, Engineers and Machinists 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:-

In lieu of the usual shaping wheels or racks which are provided with teeth gradually
increasing in width and in using which a separate wheel or rack is required for each
different size or shape of spool to be filled we employ two toothed pinions which when
placed end to end and close together make up the minimum width of traverse of the
thread guide and which are expanded automatically as the spooling proceeds in order
to adapt them to the gradually increasing width of traverse required for filling the
wider portions of the spools extending over the conical sides thereof. As represented
in the accompanying drawings (which illustrate our invention as applied to a thread
spooling machine of the Conan" type) in side elevation at figure 1 in plan at
figure 2 and in front elevation at figure 3, the shaping pinions or wheels A, A, are
fitted upon a shaft B which is turned back by means of a spring or weight C as each
tooth is in turn released by the travelling pins or fingers D, D) which are traversed by
a right and left threaded screw spindle E and operate the thread guide in the ordinary
way; and the wheels A, A, are so keyed or secured on the shaft that either or both
may slide thereon and be moved to separate or expand them as indicated by the
dotted lines. The expanding movement may be effected in various ways one con-
venient plan being to form collars a a on the ends of the wheels A, A, into which are
fitted levers F, F, operated by inclines or wedges G, G, fitted adjustably on a plate H
which is slowly traversed in a slide I by a cam J on the shaping wheel shaft or as
shown on a shaft K driven thereby the said cam acting on a projecting arm i on the
plate H; or an incline, wedge or cam may be fitted to act directly or through other
mechanism on the wheels A, A, to separate or expand them gradually as the shaft
turns and a fresh tooth on the wheels is presented to the travelling pins or fingers D D
to regulate the traverse of the thread guide.
The fingers D, D are formed on arms L, L carrying each a half nut 7 adapted to
engage the screw shaft E against which the nuts are pressed by rollers M acted on by
springs N; and as the fingers are traversed in one direction to a point at which one
finger D passes out of the teeth of one of the wheels A, A, the half nut on the
arm L carrying said finger is thrown up by the pressure of the spring N into gear
with the screw shaft E whilst the wheels A, A, being acted on by the weight turn
slightly on being freed from the one finger D and depress the other finger throwing

page_text: the corresponding half nut out of gear the direction of motion being thus reversed
and the wheels A, A, being advanced a tooth. This reversal of motion and advance
of the wheels A, A, takes place as each finger escapes from the teeth of the wheels
and as the cam J is rotated in unison with the wheels A, A, and acts through the
plate H and inclines G, G, the said wheels are gradually expanded and the traverse
of the fingers is extended. The action of the screw shaft and half nuts in operating
the fingers D D is similar to that of the corresponding parts in existing machines of
the "Conant" type.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. The combination of parts constituting the improved automatic shaping mechanism
for thread spooling machines substantially as hereinbefore described with reference to
the annexed drawings.
2. In thread spooling machines the use of the automatically expanding shaping
wheels A, A, for varying the traverse of the thread guide substantially as hereinbefore
described with reference to the accompanying drawings.
