I, MATTHEW HODGART WHITE of Paisley in the County of Renfrew, North Britain,
Engineer Machinist and Tool maker partner of the firm of Messrs. Thomas White and
Sons Engineers, Machinists and Tool makers there, do hereby declare the nature of
this invention to be as follows:-
This Invention which relates to a Double, self-acting spool Finishing Machine
consists of two upright standards supporting a horizontal bed, on which are erected
all the constituent parts of the machine.
A longitudinal slide spindle is mounted at each end of this horizontal bed, and at
the centre of the bed is situated the headstock with revolving spindle, the said spindle
having an arbor or mandrel at each end, by which arrangement (the axes of the
revolving and sliding spindles being all in the same straight line) two spools can be
under operation at once.
The cutting tools, which are of the ordinary kind for turning spools are carried on
four transverse slides capable of being moved to and fro in a direction at right angles
to the bed, two of these slides being situated at the front and two at the back of the.
machine, one front slide and one back slide being placed in close proximity to each
end of the revolving spindle. The counter shaft, which extends longitudinally from
one end of the machine at the back of the same to a short distance beyond its centre,
is carried in bearings, one of which is situated in the lower part of one of the standards,
whilst the other is formed by a bracket bolted to the side of the bed. This counter
shaft is provided at an intermediate point of its length with the ordinary fast and
loose pulleys, and has keyed to it, at its inner end, a crank disc which through a
connecting rod and lever, actuates a rocker shaft extending along the back of the
machine at a higher level than the counter shaft, and carried on horizontal projecting
brackets cast on the back of the bed. The two sliding spindles hereinbefore referred
to are actuated from the rocking shaft in the usual well known manner. The four
transverse slides are for the major portion of their travel, also actuated from the
rocking shaft by the ordinary arrangement of levers adopted in tools of this class, but

page_text: the cutters are finally brought into contact with the spool blocks, by the action of
weights only, the said weights being keyed to the rocking shaft. The introduction of
these weights into the construction of self-acting spool finishing machines always
ensures of the transverse slides, which carry the cutters coming to a dead stop, thereby
producing better spools than by the ordinary method. The lower end of the already
referred to connecting rod is provided with a long slot in which the crank pin of the
disc may rotate without communicating any motion to the rocking shaft. This action
occurs when the strain on the machine at any time is greater than the working strain
for which the weights are regulated, thereby preventing any damage being done to
the machine by overstraining.

page_text: I, MATTHEW HODGART WHITE of the firm of Messrs. Thomas White and Sons of
Paisley in the County of Renfrew North Britain, Engineer, Machinist and Tool
Maker 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 a double self acting spool finishing machine consists
of two upright Standards supporting a horizontal bed, in and upon which the various
parts of the machine are erected.
A fixed poppet head with longitudinal sliding spindle is mounted at each end of this
horizontal bed, and at the centre of the bed is situated the headstock with revolving
spindle the said spindle having a double flanged pulley at its centre and a fluted arbor
or mandrel at each end, by which arrangement (the axes of the revolving and sliding
spindles being all in the same straight line) two spools can be under operation at
once.
The cutting tools, which are of the ordinary kind for turning spools are carried on
four transverse slides capable of being moved to and fro in a direction at right angles
to the bed, two of these slides being situated at the front and two at the back of the
machine, one front slide and one back slide being placed in close proximity to each
end of the headstock with revolving spindle. The counter shaft which extends
longitudinally from one end of the machine at the back of the same to a short distance
beyond its centre, is carried in bearings, one of which is situated in the lower part of
one of the standards, whilst the other is formed by a bracket bolted to the side of the
bed. This counter shaft has keyed to it, at its inner end, a crank disc which through
a connecting rod and lever, actuates a rocker shaft extending along the back of the
machine at a higher level than the counter shaft and carried on horizontal projecting
brackets cast on the back of the bed. The two sliding spindles herein before referred
The four
to are actuated from the rocking, shaft in the usual well known manner.
transverse slides are also actuated from the rocking shaft by the ordinary arrange-
ment of levers adopted in tools of this class, the first cut to the spool blocks being
given by the cutters of the front sides whilst the finishing cut is performed, by those
of the back slides. In my invention, however besides the ordinary mechanisin for
working the back slides, I introduce weighted levers so keyed to the rocking shaft
that as they fall forward their gravity ensures that the cutters of the back slides are
always brought to a dead stop at the same point thereby producing more exact and
better spools than with the ordinary mechanism alone. The lower end of the already
referred to connecting rod is provided with a slot in which the crank pin of the disc
may rotate without communicating any motion to the rocking shaft. This action
occurs when the strain on the machine at any time is greater than the working strain
for which the weights are regulated thereby preventing any damage being done to the
machine by overstraining.

page_text: In order that my said Invention may be most fully understood and readily carried
into effect, I will proceed to describe the drawings hereunto annexed:
Fig. 1. is a front elevation of a double self acting spool Finishing machine con-
structed according to and constituting my present invention.
Fig. 2 is a plan of the same.
Fig. 3. is a transverse section through the slides taken on the line A. B, Figure 2,
whilst Figure 4 (Sheet 3) is a detailed front view of the hoppers.
In carrying out the object of this Invention a framework is provided, consisting of
two standards C, and a horizontal bed D in and upon which the various parts of the
machine are erected. Mounted at each end of the horizontal bed D), is a fixed poppet
head E, provided with a longitudinal sliding spindle, and at the centre of the bed is
situated the headstock F, with revolving spin fle, the said revolving spindle having a
double flanged pulley G at its centre and a fluted arbor or mandrel H at each end.
By this arrangement of the headstock F and poppet heads E (the axes of the revolving
and sliding spindles being all in the same straight line) two spools can be under
operation at once. The cutting tools which are of the ordinary kind for turning
spools, are carried on four transverse slides capable of being moved to and fro in a.
direction at right angles to the bed D, two of these slides I being situated at the front,
and two at the back of the machine, one front slide I and one back slide 1 being
placed in close proximity to each end of the headstock F. The disc or counter shaft J
which extends longitudinally from one end of the machine at the back of the same to
a short distance beyond its centre, is carried in journal bearings, one of which is
situated in the lower part of one of the standards C, whilst the other is formed by the
bracket K bolted to or cast on the side of the bed D. On the disc or counter shaft J
the belt pulley M is loose, whilst the male pulley Q and clutch L with its levers l,
are connected to the said shaft and arranged to slide on a feather on the same, the
machine being started or stopped accordingly as the sliding male pulley Q is in or out
of gear with the loose belt pulley M. This sliding movement of the clutch L and its
levers (which levers actuate the male pulley Q) is effected by two projecting pins N'
on the forked lever N which engage with cods fitted into a groove L' in the periphery
of the clutch L the forked lever N being actuated through the interposition of the
transverse shaft O by the hand lever conveniently situated at the front of the
machine. In lieu of the before mentioned friction clutch arrangement and loose belt
pulley M, fast and loose pulleys with the ordinary belt shifting gear or their equiva-
lents may be substituted. Keyed to the inner end of the counter shaft J is a crank
disc R which through a connecting rod S and lever T actuates a rocker shaft U
extending along the back of the machine and carried on horizontal projecting
brackets V cast on the back of the bed 1 at each end of the same, and a bracket K
in the centre. The two sliding spindles in the poppet heads E are actuated from the
rocking shaft U in the usual well known manner by means of the levers W. The
four transverse slides are for the major portion of their travel also actuated from
the rocking shaft U by the ordinary arrangement of levers adopted in tools of this
class; the two front slides I being each moved by a lever X on the rocking shaft U
through the intervention of a rod Y which is located under the slides I and l' and
passes from the back to near the front of the machine whilst the two back slides 1' are
each actuated from a lever X¹ by a rod Y'. The cutters of the front slides I begin
the cutting of the spool blocks, before those of the back slides l' come into operation.
The cutting is continued in each of the front slides I until its forward motion ceases
by the projecting part at the fore end of the rod Y losing its hold of the tappet r, and,
as the tappet is secured to the under side of the said slide, consequently its control
of the same.
The front slide I is then brought back to its first position by the action
of a hanging weight m. The rod is put in and out of gear with the tappet by
means of the pin Z which is attached to the rod Y and moves within the curved slot
or slots
thus causing the fore end of the said rod to deviate out of the horizontal
path which it would naturally take if rigidly connected to the front slide I. The
finishing cut to the spool is performed by the cutters of the back slides P'.
In addition to the ordinary mechanism of the rocking lever X', and rod Y, for

page_text: actuating each of the back slides I, I introduce a weighted lever b, so keyed to the
rocking shaft U that as the lever b falls forward its weight ensures that the cutters of
the back slide I' are always brought to a dead stop thereby producing better spools
than by the ordinary mechanism alone. The lower end of the already referred to
connecting rod S is provided with a slot in which the crank pin R¹ of the disc R may
rotate without communicating any motion to the rocking, shaft U or the same result
may be attained by means of the nut n in adjusting the friction clutch to the pressure
desired. This action occurs when the strain on the machine at any time is greater
than the working strain for which the weighted levers are regulated, thereby pre-
venting any damage being done to the machine by overstraining.
The operation of the machine is as follows.
The rough blocks having been placed in the runs or hoppers d on each side of the
headstock F the said hoppers d are carried forward in line with the spindles by the
roller or slide spindle of the poppet head E acting on the Cam p till the blocks are
caught by the centre points e and mandrels H, when the hoppers d rise clear of the
front slides by the action of the rollers on the opposite end of Camp to allow the cutters
to operate as hereinbefore described. The finished spools are then knocked off the
mandrils H by the action of the drop levers or "knockers off"f. The lower end of each
of the said drop levers is rigidly attached by means of the stay rod g to the corre-
sponding end of the lever whose upper end is secured to the longitudinal sliding
spindle of the poppet head E. As this sliding spindle is moved forward by the action
of the lever W when a rough block is about to be operated upon the drop lever f,
which is provided at its top end with an eye, is necessarily carried with it until the
mandril H passes through the said eye, and the block is gripped by the mandrel H
and Centre point e. After the block has been operated upon and the spool is finished
the backward motion of the sliding spindle and drop lever f knocks off the spool
which falls into a suitable receiver.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
First In a double self acting spool finishing machine the central headstock F in
combination with the two fixed poppet heads E substantially as described and for the
purpose specified with reference to the annexed drawings.
Second The weighted levers b keyed to the rocking shaft U, to ensure the cutters
of the back slides I coming to a dead stop as hereinbefore described with reference to
Fig. 2. of the accompanying drawings.
