An Improved Form of Apparatus for Branding or Black-marking
Wood Spools.
We, JOHN CLAYTON and DAN CLAYTON, of Thornton Road, Bradford, in the County
of York, Bobbin Manufacturers, do hereby declare the nature of this invention to be
as follows:-
-
Our invention relates to a new form of apparatus for branding or black marking
wood spools. Hitherto this has been done by manual labour, effected by means of
the workman placing a hard piece of wood or other substance in contact with a
rapidly revolving spool in a lathe; the distance apart at which the marks have been
made upon the spool having been roughly guessed at.
It is our intention to brand or black mark spools by mechanical means, and this we
accomplish by a moving headstock or pedestal in which are fixed by screws or other
means a suitable number of tools, and by means of a lever operated by a workman,
such tools are brought into contact with the rapidly revolving spool, whereby the
branding or black marking is instantaneously effected. The tools are adjustable in the
headstock so that the depth at which the spools are branded can be regulated. It is
customary for some of the black markings to be polished or burnished, and this we
effect by having the branding tools in a headstock capable of oscillating to and from
the revolving spool, the arrangement being such that when the branding has been
effected the toolholder is caused to tilt (by means of a spring or other means) so as
to cause the branding tools to dwell a moment in contact with the revolving spool,
whereby the branding is polished or burnished almost simultaneously with the black-
marking.
By the employment of machinery for branding or blackmarking spools as herein
described, the work is rapidly performed, and a considerable saving of time is
effected.

An Improved Form of Apparatus for Branding or Black-marking
Wood Spools.
We, JOHN CLAYTON, and DAN CLAYTON of Thornton Road, Bradford, in the County
of York, 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 relates to a new form of apparatus for branding or black marking
wood spools. Hitherto, this has been done by manual labour, effected by means of the
workman placing a hard piece of wood or other substance in contact with a rapidly
revolving spool in a lathe; the distance apart at which the marks have been made
upon the spool having been roughly guessed at.
It is our intention to brand or black-nark spools by mechanical means, and this we
accomplish by a moving tail-stock and a pedestal or rest in which latter are fixed, by
screws or other means, a suitable number of tools; and, by means of a lever operated
by a workman, such tools are brought into contact with the rapidly revolving spool,
whereby the branding or black marking is instantaneously effected. The tools are
adjustable in the rest so that the depth at which the spools are branded can be

page_text: regulated. It is customary for some of the black-markings to be polished or burnished
and this we effect by having the branding tools in a rest capable of oscillating to and
from the revolving spool, the arrangement being such that when the branding has
been effected the tool-holder is caused to tilt (by means of a spring or other means)
so as to cause the branding tools to dwell a moment, in contact with the revolving
spool, whereby the branding is polished or burnished almost simultaneously with the
black marking.
By the employment of machinery for branding or black marking spools as herein
described, the work is rapidly performed, a id a considerable saving of time is
effected.
In the accompanying drawings,
Fig. 1 is a front elevation of a machine constructed according to our Invention;
Fig. 2, a plan of same;
Fig. 2 a similar plan, but with the lever H pulled forward and showing the machine
in operation.
Fig. 3 is an end view;
Fig. cross section through the pedestal or rest, showing more clearly the tools for
black-marking the spools or bobbins ;
Fig. 5 is a front elevation and
Fig. 6 a side view, of the apparatus we employ when we desire to polish or burnish
the black-markings.
Figs. 7 and 8 are enlarged views showing bobbins with black-markings thereon
Fig. 8 having the uppermost black-marking barnished.
The apparatus we employ consists in a lathe having tail-stock A, and head-stock B,
and a pedestal or rest C, having the branding tools, of iron or steel or other suitable
metal adjustable therein. The bed plate E has arms or brackets F, F, carrying the
shaft G moving on the threaded centre-pins /,/. To this shaft G is bolted a lever H,
having a handle h, worked by the operative and capable of giving the said shaft a
partial turn. The pedestal or rest (, fixed to the bed plate E, being connected to its
base C by the tenon and mortise C, is made to slide backwards and forwards in the
manner hereinafter explained. The tools D are capable of adjustment, by means of
the screws d and a spanner or other suitable device, so that the depth at which the
spools or bobbins are branded can be regulated. To the rest C, a forked connecting
arm or rod C³ is pin jointed, its other end being similarly jointed to a crank C
bolted to the shaft G. The tail-stock A is cylindrical and contains, instead of the
usual screw, a piston a, working therein, having at one end the usual spindle a' and
centre a. To that end of the piston a which carries the spindle a' is bolted a crank
arm a, a similar arm 3 being loosely attached to the live-spindle 6 of the head-stock B,
which latter is of ordinary construction. These two arms a³ and 63 carry a rod or
spindle a capable of adjustment, by means of the screw, to suit the varying lengths
of the spools or bobbins operated on. A lever J working on a fulcrum j, in a bracket
attached to the tail-stock A, is connected to the piston a by pin ax and link . The
other end of the lever J is formed as a cam J¹ which works in a guide in the lever H,
being aided in its movements by the rollers ³, h².
In Figs. 5 and 6 we have shown the apparatus which we employ when burnishing
as well as black-marking the bobbins and which consists of a modified form of the
rest C before described. The tool D, in this case of wood, is contained in a rocking
carrier D', fast on the shaft C³, and is prevented from working loose in the said
rocking carrier by means of the screws d', d², d³. By adjusting the screw d on the
arm D the angle of the carrier D' with relation to the shaft C5 may be regulated.
The bracket C carries the shaft C turning loosely therein and is capable of sliding
movement on the tenon Cx to adjust the tool to varying lengths of bobbins. On
the back of the rocking carrier D is a bracket abutting against a stop C on the
rest. Around this stop C7 a spring, as shown in Fig. 6, may be coiled to cause
the tool D (by the force it exerts against the bracket d) to dwell a moment in contact
with the revolving spool or bobbin and so effect the burnishing operation; or, a weight

page_text: on the strap Cs (or a chain may be substituted for the strap) fastened to the rocking
carrier D', may be employed for the same purpose. In the latter case a roller (
should be attached to the bed-plate E to minimize the wear on the strap C³.
In manipulating with this machine, rotary motion is communicated to the head-
stock. B in the usual way by band from the main driving source. The tools D located
in the rest C having been previously adjusted by means of the screws d, the operative
cominences by placing the bobbin on the dead spindle a² which is of a size to
suit the core of the bobbin. The length of the bobbin is now ascertained, and the
distance from its top end to the end of the dead spindle a² nearest to the spindle a¹ is
gauged, and the arm 63 adjusted on the rod at to suit the measured length. The
lever H is now pulled forward by the handle and this, through the medium of
the cam J, operates the lever J pushing the piston a home in its cylinder and
causing the live spindle b¹ to enter the core of the bobbin at its other end. The
motion of the lever H causing a partial revolution of the shaft G, at the same time
operates the crank C, attached to the rest C by the connecting rod 3, sliding the
said rest on its groove C and bringing the tools D against the revolving bobbin which
becomes marked almost instantaneously. The lever H is now pushed back and so
causing the arm 63 to knock the bobbin off the live spindle b, forcing back the
piston a, and simultaneously withdrawing the rest C. Supposing four tools have been
used, as shown in Figs. 2 and 2, the bobbin will now have the appearance indicated
by Fig. 7; 1, 2, 3, 4, representing the black-markings. The burnishing may be
effected, on the same machine, by removing the rest C from its tenon C², dis-
connecting it from the connecting rod C³ and substituting in lieu thereof the modified
form of rest shown in Figs. and 6; or, the burnishing may be accomplished on
another machine provided with the necessary burnishing apparatus.
In operating
with the burnisher the same movements of the lever H and crank C³ are gone
through as for the black-marking just described. In this form of rest the spring
at C (or the weight on the strap (3) causes the rocking carrier D₁ and tool D to
lean over towards the bobbin, and in the forward movement of this rest the tool D
striking against the bobbin is tilted up until the bracket dabuts against the
stop C. This part of the branding being now accomplished the lever H is pushed
back again, and the tool D is partially retarded in its backward motion by the
spring at (or the weight on the strap C³) thus causing the necessary "dwell" of
the said tool on the bobbin and producing a kind of sweeping or rubbing action
on the bobbin which, effects the burnishing of the part just branded almost simul-
taneously. The bobbin will now have the appearance detailed in Fig. 8 ; being
the burnished part. Although we have described this Invention with regard to the
branding or black-marking of bobbins or spools only it will be readily understood
that it may be utilized without alteration for branding other articles of a like
nature, such as, for instance, tool handles, brush and broom handles, school pencil
cases, toy skittles and toy catapult handles.
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 :-
:―
Firstly. The adaption of a lathe for the purposes of black-marking and burnishing
bobbins or spools substantially in the manner and by means of the mechanism herein-
before described and shown on the Drawings.
Secondly. The tool holder, rest or pedestal C, having the tools D adjustable therein
by means of the screws d, and connected by the connecting rod C³ and crank C to
the shaft G substantially as herein before described and shown on the Drawings.
Thirdly. The lever H bolted to shaft G and having the guide h' and guide rollers /
in combination with the lever J and its cam J and link j, said lever J being
fulcrummed at j, substantially in the manner and for the purposes described and
shown.
