Improvements in Apparatus for Turning or Shaping Reels or
Bobbins.
We, WALTER MCGEE and DAVID MCGEE of the Firm of Walter M°Gee &
Son, Engineers, Paisley, Renfrewshire and JAMES BALDERSTON, Manager
Anchor Thread Mills, Paisley aforesaid do hereby declare the nature of this
invention to be as follows:-
1-
This invention which relates to apparatus for turning cutting or shaping reels or
bobbins has for its object to render entirely self-acting the several parts of the
apparatus which co-operate in the cutting of the finished reels or bobbins from the
wooden blanks and thereby increase the rate of production.
The improved apparatus comprises a framing supporting the usual headstocks
the one carrying the rotating spindle or mandrel on which the reel blank is turned
and shaped and the other fitted with the sliding spindle or centre which serves to
feed forward the blank from a hopper on to the rotating spindle or mandrel. The
sliding spindle or centre instead of being operated by a hand lever as usual is
automatically reciprocated at the required intervals by means of a cam wheel or
inclined quadrant rotated or oscillated through gearing or by means of a connecting
rod from a revolving shaft carried on the framing behind the headstocks or by a
lever actuated by a cam on the running shaft.
This shaft has also fitted on it a can or cams which act directly or through
connecting rods to positively retract the tool holders which are brought forward on
the usual slide rests to bring the cutting tools into operation by means of strong.
springs or by cords or chains and weights. On the same shaft is fitted a bevel
wheel gearing with a bevel wheel on a transverse shaft on which is a cam or tappet
by means of which a sliding piece is actuated to throw off the finished reel from the
rotating spindle or mandrel, a handing wheel being also fitted on said transverse
shaft to provide for turning the belt driven shaft by hand when desired for the
purpose of adjusting the tools and other parts.
In lieu of providing this transverse shaft the handing wheel may be keyed on
the belt driven shaft and a crank or cam fitted on its end to actuate a lever for
throwing off the finished reel or bobbin.
In order to provide for stopping either of the slides carrying the cutting tools
when jammed or blocked by a bobbin blank, the said slides may be connected
together through a quadrant hung upon a stud fixed to the machine head or through
a chain and pulley so that when one set of tools is jammed the other set is prevented
from advancing, or for this purpose a bar having an inclined surface resting on a
pin may be employed to act as a stop between the slides when any hitch occurs to
prevent the movement of either of the slides.

We, WALTER MCGEE and DAVID MCGEE, of the Firm of Walter M°Gee &
Son, Engineers, Paisley, Renfrewshire, and JAMES BALDERSTON, Manager,
Anchor Thread Mills, Paisley, aforesaid, 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:-
This invention which relates to apparatus for turning, cutting or shaping reels or
bobbins has for its object to render entirely self-acting the several parts of the
apparatus which co-operate in the cutting of the finished reels or bobbins from the
wooden blanks and thereby increase the rate of production.
a
As illustrated in front elevation at Figure 1, in plan at Figure 2 and in detail
at Figure 3 of the accompanying drawings the improved apparatus comprises
framing A supporting the usual headstocks B the one carrying the rotating spindle
or mandrel C on which the reel blank is turned and shaped and the other fitted
with the sliding spindle or centre D which serves to feed forward the blank from a
hopper E on to the rotating spindle or mandrel C. The sliding spindle or centre D
instead of being operated by a hand lever as usual is automatically reciprocated at
the required intervals by means of a rotating cam wheel or inclined quadrant F
oscillated by means of a connecting rod G from a crank or disc H keyed on a
revolving shaft I carried on the framing A behind the headstocks B, or through
gearing or by a lever actuated by a cam on the said shaft.
This shaft I has also fitted on it two cams which act directly or through
connecting rods to positively retract the tool holders K which are brought
forward on the usual slide rest L to bring the cutting tools into operation by
means of strong springs or by cords or chains and weights M. Or as shewn
particularly by Figures 2 & 3 one cam only may be used in which case the cam J
acts against a roller j centred on one end of a connecting rod j' whose other end
is attached to and actuates one of the tool holders K, the other tool holder being
actuated through a connecting rod and double ended lever j secured on the
framing of the machine from a pin j fixed in the connecting rod j', the object of
so connecting the tool holders K being to stop the advancing movement of the tools
should the bobbin blank become jammed.
On the shaft I is fitted a bevel wheel N gearing with a bevel wheel O on a
transverse shaft P on which is a cam or tappet Q by means of which a sliding
bar R having an eye piece is actuated against the action of a spring to throw
off the finished reel from the rotating spindle or mandrel C, a handing wheel S
being also fitted on said transverse shaft P to provide for turning the belt
driven shaft by hand when desired for the purpose of adjusting the tools and
other parts.
In lieu of providing this transverse shaft the handing wheel S may be keyed on
the belt driven shaft I and a crank or cam fitted on its end to actuate a lever for
throwing off the finished reel or bobbin.
In order to provide for stopping the sliding tool holder K carrying the finished
tools when the roughing tools on the other holder K are jammed or blocked by a
bobbin blank, the actuating rods j,, of the said tool holders may be connected
together as shewn by Figure 3 through a quadrant or double ended lever j³ centred
upon a stud in a bracket fixed to the machine head so that when one set of
tools is jammed the other set is prevented from advancing; or for this purpose a
bar having an inclined surface resting on a pin may be employed to act as a
stop between the slides when any hitch occurs to prevent the movement of either
of the slides. Fio. 4 illustrates such an arrangement in which a bar S, pivoted at

pin fixed in a stationary part of the machine, a pin on the other tool.
holder K abutting against said bar S when any hitch occurs to prevent the move-
ment of the slide to which the bar S is pivoted. If desired this arrangement can be
duplicated.
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. A machine for turning or shaping reels or bobbins, the parts of which are
constructed, combined and operated substantially as described with reference to the
annexed drawings.
2. In apparatus for turning or shaping reels or bobbins the arrangement of the
cam wheel or quadrant F operated from the rotating cam shaft to automatically
reciprocate the sliding spindle or centre which feeds forward the bobbin blanks,
substantially as described with reference to the annexed drawings.
3. In a machine for turning or shaping reels or bobbins the application of direct
acting cams for retracting the tool holders in conjunction with springs or weights
for feeding them forward substantially as described with reference to the annexed
drawings.
4. In a machine for turning or shaping reels or bobbins the combination of
devices for knocking off the finished bobbin, substantially as described with
reference to the annexed drawings.
5. In a machine for turning or shaping reels or bobbins the provision of a stop
motion substantially as described for preventing the advance of the finishing tools.
when the first or roughing cutters are jammed.
