A New or Improved Machine for "Roughing" Wood in the Process
of Manufacturing Bobbins, Spools, Tubes, and other like
Articles.
We, JOHN CLAYTON and DAN CLAYTON, of Thornton Road, Bradford, Yorkshire,
Bobbin Manufacturers, do hereby declare the nature of this invention to be as
follows:-
:-
Our invention consists in arranging and constructing a new form of machine for
"roughing" pieces of wood in the earlier process of manufacturing bobbins, spools,
tubes, and other like articles.
In constructing a machine according to our invention, we employ any ordinary form
of lathe bed or gantry provided with a fast and loose headstock, the former of which
is made with a central spindle driven by belt or other means. This central spindle
carries a face plate and a large spur wheel in gear with which are a number of
pinion wheels, each pinion carrying a central spindle or stud, all of which are caused
to revolve individually by the large spur wheel. I also mount upon the central
spindle another dise or face plate provided with spindles or studs corresponding in
number to those on the other face plate, which are driven by the pinion wheels.
The blocks of wood to be roughed or shaped into bobbins spools or tubes are made
secure between the two opposite spindles and the latter set of spindles are capable of
slicing end wise in slots in their face plate, so that the operative, when placing the
blocks of wood between the two centres, forces the sliding spindles against the
blocks of wood so as to hold them in position, by which they are caused to rotate,
in addition to each individual block of wood having a rotary motion, which is
imparted to them by the pinion wheels. The discs carrying the spindles also revolve;
bringing each block of wood into contact with rapidly rotating saws or knives placed
upon a suitable arbour driven at a quick speed, by which means each block of wood,
whilst being carried around by the discs or face plates, is roughly shaped by the
rapidly rotating knives or saws. During the time the blocks of wood are in contact
with the cutting knives, the sliding spindles, each outward end of which is provided
with a friction bowl, is arranged to slide over a cam-shaped plate which forces each
spindle tightly against each block of wood so that during the cutting operation they
are held rigidly in position to bear the strain necessary for cutting.
By the employment of a machine as herein described, the roughing of the bobbins
is rapidly effected, and at very little cost.

We, JOHN CLAYTON, and DAN CLAYTON, of Thornton Road, Bradford, Yorkshire,
Bobbin Manufacturers, 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 invention consists in arranging and constructing a new form of machine for
roughing" pieces of wood in the earlier process of manufacturing bobbins, spools,
tubes and other like tiles

page_text: In constructing a machine according to our invention, we employ any ordinary
form of lathe bed or gantry provided with a fast and loose head-stock, the former of
which is made with a central spindle driven by belt or other means. This central
spindle carries a face plate and a large spur wheel in gear with which are a number
of pinion wheels each pinion carrying a central spindle or siud, all of which are
caused to revolve individually by the large spur wheel. We also mount upon the
central spindle another disc or face plate provided with spindles or studs corre-
sponding in number to those on the other face plate, which are driven by the pinion
wheels. The blocks of wood to be roughed or shaped into bobbins, spools or tubes,
are made secure between the two opposite spindles and the latter set of spindles are
capable of sliding endwise in slots in their face plate, so that the operative, when
placing the blocks of wood between the two centres, forces the sliding spindles
against the blocks of wood so as to hold them in position, by which they are caused
to rotate, in addition to each individual block of wood having a rotary motion, which
is imparted to them by the pinion wheels. The dises carrying the spindles also
revolve, bringing each block of wood into contact with rapidly rotating saws or knives
placed upon a suitable arbour driven at a quick speed, by which means each block
of wood, whilst being carried around by the discs or face plates, is roughly shaped
by the rapidly rotating knives or saws. During the time the blocks of wood are
in contact with the cutting knives, the sliding spindles, each outward end of which
is provided with a friction bowl, are arranged to slide over a cam shaped plate
which forces each spindle tightly against each block of wood so that during the

the bobbins is rapidly effected, and at very little cost.
Referring to the drawings.
Fig. 1 is a front elevation of a machine constructed according to our invention;
Fig. 2 is an end view of same, taken from the left side, and
Fig. 3 an end view, taken from the right side.
A is the lathe bed or gantry, B the head-stock in which is mounted a hollow shaft C,
having the fly-wheel or pulley D fast thereon, and to which rotary motion is imparted
by the belt E or other suitable means. The hollow shaft C carries one end of a shaft F
centred loosely therein, the other end being mounted loosely in the bearing G which
is fixed to the bed A and takes about the place of the tail-stock in an ordinary turning
lathe. This shaft F carries two face-plates or discs H and J keyed thereon. The
disc H is perforated with a number of holes, arranged radially and equidistant, near
the periphery and containing a like number of spindles h. Each of these spindles h
has at one end a pinion fast thereon and gearing with a spur wheel H', see
Fig. 2, on the hollow shaft C with which it revolves. The spindles have at their
opposite ends spikes to prevent the work from twisting and they are also provided
with the centres on which the work revolves, and with the collars to keep them
in position. The disc H is also provided on its periphery with cogs forming the
spur-wheel H in gear with the worm-wheel K which is keyed to the arbour K¹
in bearings across the lathe-hed A; the said arbour K' having at one end the bevel
pinion K2 gearing with a bevel-wheel L on a shaft L' which has its bearings in
brackets bolted to the front of the hed A and provided with speed pulley L² and L³,
driven by the belt. L. The disc J is perforated with a number of holes in manner.
corresponding to the perforations in the disc H and exactly opposite them and carries
a number of spindles j, loose in the said holes and disposed with their. centres j¹
exactly opposite to the centres h³, and with the said spindles arranged in the same
manner as the spindles in the disc H, before mentioned. This disposition of the
discs H and J forms, as it were, a compound lathe, each spindle h having an
independent motion; the spur-pinions revolving each individually, and the worm
wheel K rotating the whole collectively, whilst the disc J, being fast on the shaft F,
in revolving carries with it the whole of the spindles ; the centres ³ and thus
corresponding respectively and individually to the live and dead centres of an ordinary
lathe. The ends of the spindles į opposite to their centres j' are each provided

page_text: with a friction bowl which bears, in the course of the rotation of the disc J,
against a cam-shaped plate M adjusted, in the manner hereinafter described, on the
bracket G the effect of this being to force the spindles j successively forward in
the direction of the opposed spindles ³, thus impelling the rough blocks of wood,
when placed on the centres, into position on the live spindles. The cam plate M
is fixed to a piston m working in a cylinder m¹ bolted to an arm m² on the bracket or
bearing G, and an L shaped lever M with fulcrum in a curved arm on the
cylinder m, by means of the weight M2 bearing against one end of the piston, keeps
the cam-plate M. hard against the friction bowls 2 on the spindles j. The disc J is
slotted across its periphery, the slots being parallel with the centres of each of the
spindles, and these latter are each provided with a pin 3 arranged to travel
longitudinally in the said slots. N is a bracketted guide bolted to the bed A, which,
as the disc J revolves, causes, by the pins 3 striking against its upper curved surface,
the spindles to slide back and return to their normal position; collars around
the said spindles preventing them from moving too far backwards, and shoulders near
their other ends preventing too much forward motion. O are a set or cluster of
circular saws or cutting knives mounted on an arbour in brackets attached to the
back of the bed A. These saws receive rotary motion from the main driving source
by means of the belt O, and the discs K and J in revolving bring the rough blocks
of wood against the said saws which shape them roughly into bobbins (or other like
objects, according to the shape of the saws) almost instantaneously. The said dises
continuing their motion bring the roughly formed bobbins against a "knocker off" P,
on a bracket bolted to the bed A, which, loosening them from the live centres ³,
deposits them into a receptacle below the lathe-bed. Meantime the bracket N, by
means of its curved upper surface acting on the pins j³, has forced the unoccupied
spindles back again in their sockets or holes in the disc J into their normal position.
The discs H and J still continuing to revolve, fresh blocks of wood (previously drilled)
are placed on the unoccupied centres and these blocks, in their turn, are brought
(by means of the cam-plate M impelling the spindles ; forward so that the blocks
are forced upon the live-centres ³) against the saws O and shaped as before described,
and so on, as long as the machine is made to revolve. R, in Fig. 1, shows one of
these rough blocks of wood on the machine previous to iis passsing the saws O, and S
represents one that has passed and been operated on by the saws.
Instead of employing the intermediate gearing K, K' and L, herein before described,
we may impart rotary motion to the shaft F direct by belt and pulley, but the mode
already specified, or some suitable modification of same, is preferable as if the
shaft were driven direct it would necessitate the use of a pulley of inconveniently
large dimensions in order to obtain the necessary slow speed of rotation of the
discs H and J.
Having now particularly described and ascertained the nature of our inven
tion and in what manner the same is to be performed, we declare that what
we claim is :-
Firstly. The arrangement of compound lathe composed of two discs or face-plates,
as H and J, both keyed on the same shaft (which is caused to revolve slowly) the
former being provided with live centres arranged radially, as h³ on the spindles h
(to which independent rapid rotary motion is imparted) and the latter being
provided with dead centres, also arranged radially, as on the spindles j, each live
centre being exactly opposite each dead centre, the whole employed for the purposes
specified or any mere modification thereof.
Secondly. The compound head-stock formed of the perforated disc H, mounted
on the shaft F and containing the live spindles with their centres and spur-
pinions (rotated by means of the spur wheel H fast on the hollow shaft C) slow
rotary motion being imparted to the said shaft F by intermediate gearing or other-
wise, substantially as described and shown on the drawings and for the purposes
specified.
Thirdly. The compound tail-stock arranged as a perforated disc J carrying the

page_text: dead spindles with their centres j', each exactly opposite each of the live centres,
the said disc J being keyed to the shaft F and revolving with it, substantially as
described and shown on the drawings and for the purposes specified.
Fourthly. The apparatus for producing the longitudinal forward motion of the
spindles in their sockets in the disc consisting of the weighted camm-plate M and
the friction bowls j substantially as described and shown.
Fifthly. The arrangement for effecting the backward or return longitudinal move-
ment of the spindles in the disc J consisting of the slots provided in the said
disc J, the pins on the spindles and the guide N with upper curved surface,
substantially as described and shown.
Sixthly. The disposition of the set or cluster of circular saws or cutting knives O
employed for roughly shaping blocks of wood and the like into such articles as
bobbins spools, or tubes (according to the formation of the cluster of saws) when
brought to bear against the said saws by means of the compound head-stock and tail-
stock before mentioned, substantially as shown and described.
Seventhly. The improved form of compound lathe or machinery for "roughing"
or roughly shaping wood and the like into articles such as bobbins, spools, tubes or
similar commodities, substantially as described and shown on the drawings or any
mere modification thereof as long as the essential features of the invention are allowed
to remain.
