PROVISIONAL SPECIFICATION.
Improvements in Profiling or Outline-shaping Machines.
We, ROBERT FREDERICK HALL, of Ferndale, Church Road, Moseley, in the
City of Birmingham, Managing Director of The Cycle Components Manufacturing
Company Limited, and CHARLES TAYLOR, of Bartholomew Street, Birmingham
aforesaid, Engineer, do hereby declare the nature of this invention to be us
follows:-
Our invention relates to improvements in profiling or outline-shaping machines,
or in other words, to machines for dressing the contour of cycle crauks and such
like articles having regular or irregular boundary edges.
Supported and sliding upon the bed of an upright framing, is a saddle bracket,
having at its fore part, a vertical slide, carrying upright bearings, wherethrough a
vertical spindle, having a shaping tool or rotating cutter at its lower end, and
horizontal driving pulley, driven by a band, its upper end, passes. The band of
this pulley is directed rearwardly over a vertical pulley, supported within bearings
of an upright bracket carried by the saddle, whilst the other portion of the pulley
takes around a long drum, made fast upon a driving shaft, and having a length
about equal to the traverse of the saddle.
The vertical slide, which governs the vertical position of the rotating cutter, is
raised and lowered by a swivelly-connected screw, passing through a screw box
formed within a rearward extension of the upper part of the vertical slide, whilst
surmounting the said screw, is a hand wheel, which on being rotated, brings the
cutter up to the work, which is clamped or bolted to the topside of a rotating table,
whose boundary edge is formed into a wormed wheel, whilst its underside has
clamped to it, a "former or "dummy," or "formers" or "dummies," corresponding
in outline or profile to the exact boundary shape which the work is to have.
"
Now this table, which is horizontal, is mounted' upon a vertrical axis or spindle,
working within bearings directed through arm portions of the framing, and with
its extreme end, which is coned; resting within a stepped support, whilst the said
table is rotated by a worm, carried upon a shaft running within bearings of the
fixed framing, and being itself driven by a worm and tangent wheel, the former
being fixed upon the end of a countershaft huving stepped pulleys, which are, in
turn, driven from like stepped pulleys upon the drum shaft before described, which
also carries fast and loose pulleys.
The former or dummy upon the underside of the table has a chamfered or inclined
profile, against which, a tracing roller or feeler, carried at the end of an outstanding
bracket, having a stem at its ioner end adjustable within an eye of the saddle,
impinges, whilst the said saddle is pulled forward, and the tracer brought constantly
up to the boundary of the former, by a weight, suspended from the one end of a
cord passing over a pulley, and attached at the other end to the saddle, or instend
of a weighted cord, a spring may be employed to bring the tracer constantly up to
the contour of the former.
By making the profile of the former inclined, the tracer can be slightly adjusted,
on wear of the former, so as to restore the tracing line to the standard size.
Assuming that such articles as cycle cranks are to be profiled, then like shaped
formers are secured to the underside of the table, and the tracing roller is then
brought to their boundary edge by the weight exercising a forward pull upon
the saddle. The work is. bolted upon the table in positions corresponding to the
formers and the said table is rotated through the worm and worm-wheel. The

cutter is then lowered and rotated in the reverse direction to that of the movement.
of the table, and as the said table rotates, the former impinges upon the tracing
roller, and through it the saddle is accordingly moved backwards and forwards in
a right line, and with the saddle, the cutter, so that the said cutter cuts the work in
a line dictated to it by the former.
When one object only at one time is being operated upon, then it will be profiled
all round, but when a series of articles are being profiled at the same time, they are
arranged upon the revolving table in such a manner that the outer edges form, as
nearly as possible, a circle, concentric with the centre of the said.table, and after
the said outer edges have been profiled the articles are turned over and their inner
edges, subjected to the action of the outter in.like! manner.

Improvements.in, Profiling, or Outline-shaping Machines.
We, ROBERT FREDERICK HALL, of Ferndale, Church Road, Moseley, in the
City of Birmingham, Managing Director of The Cycle Components Manufacturing
'Company, Liniited, and CHARLES TAYLOR, of Bartholomew Street Birmingham
aforesaid, Engineer, 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 improvements ingprofiling or outline-shaping machines,
or in other words, to: machines for dressing the contours of cycle cranks, and such
Jike articles having regular or..irregular boundary edges.
Supported and sliding upon the bed of..an upright framing,. is a saddle bracket
having at its fore part, a vertical slide, carrying, upright bearings, wherethrough; a
vertical spindle, having a shaping tool or: rotating. cutter at its lower end, and a
horizontal driving pulley, driven by a band, at its upper end, passes. The band of
this pulley is directed rearwardly over. a vertical, pulley, supported within bearings
of an upright. bracket carried by the saddle, whilst the other portion of the band
takes around a long drum, made fast upon a driving. shaft,,and, having a length
about equal to the traverse of the saddle.
"The vertical slide, which governs the vertical position of the: rotating cutter, is
raised and lowered by a swivelly connected screw,..passing through a screw box
formed within a rearward extension of the upper part of the vertical slide, whilst
surmounting the said screw, is a hand wheel, which, on being, rotated brings the
cutter up to the work, which is clamped or bolted to the topside of a rotating-table,
whose boundary edge is, formed into a worm wheel, whilst its underside has
clamped to it, a "foriner" or "dummy" or "formers" or "dummies," curre-
sponding in outline or profile.. to .the, exact boundary, shape which the work is to
have.
Now this table, which is horizontal, is mounted upon a vertical axis. or spindle,
working within bearings directed througli, arm, portions of the. framing; and with
its extreme end, which is coned, resting within a stepped support, whilst the said
table is rotated by a worm, carried upon a shaft running within bearing of the fixed
framing, and being itself driven by a worm and tangent wheel, the former being
fixed upon the end of a countershaft having stepped pulleys, which are, in turi,
driven from like stepped pulleys upon the drum shaft before described, which also
carries fast and loose pulleys.

page_text: The former or dummy upon the underside of the table has a chamfered or
inclined profile, against which, a tracing roller or feeler, carried at the end of an
outstanding bracket, having a stem at its inner end adjustable within an eye of the
saddle, impinges, whilst the said saddle is pulled, forward, and the tracer brought
constantly up to the boundary of the former, by, a. weight, suspended from one end'
of a cord, passing: over a pulley, and attached at the other end to the saddle. Or
instead of a weighted cord, a spring may be employed to bring the tracer constantly:
up to the contour of the former.
By making the profile of the former inclined the tracer can be slightly adjiisted,
on wear of the former, so as to restore the tracing line to the standard size..
Assuming that such articles as cycle cranks are to be profiled, then like shaped:
formers are secured to the underside of the table, and the tracing roller is then
brouglit to their boundary edges by the weight exercising a forward pull upon the
saddle. The work is bolted upon the table in positions corresponding to the
formers and the said table is rotated through the worm and worm-wheel.
The cutter is then lowered and rotated in the reverse direction to that of the:
movement of the table, and as the said table rotates, the former impinges upon thic
tracing roller, and through it the saddle is moved backwards and forward.in a right
line, and with the saddle, the cutter, so that the said cutter cuts the work. in a line
dictated to it by the former.
When one object only at a time is being operated upon, then it will be profiled
all round, but when a series of articles are being profiled at the same time, they are
arranged upon the revolving table in such a manner that the outer edges form, as
nearly as possible, a circle, concentric with the centre of the said table, and after
the said outer edges have been profiled, the articles are turned over, and their
inner edges subjected to the action of the cutter in like manner.

or outline shaping machine.constructed, arranged and provided with improvements
in accordauce with our invention.

page_text: Supported and reciprocating upon the bed a', of an upright framing, having a
foot a² and carrying brackets a, a, a, is a saddle or sliding bracket b, provided at
its fore part with a vertical slide c, working in a V shaped groove in the bracket b
and having upright bearings c', wherethrough a vertical spindle c', carrying a
milling tool or rotating cutter c, at its lower end and a horizontal driving pulley c',
at its upper end, passes. d is a band passing round the said pulley, and then
directed rearwardly and passing over a pair of pulleys &', mounted in bearings carried
by an upright bracket 63, supported by the rear part of the saddle. The other
part of the band passes around a drum d, made fast upon a shaft d³, carried
within bearings d, fitted within a bracket do, and side of the upright framing a, which
said shaft carries.cone pulleys de, at the outer end and loose and fast pulleys d', d³,
at the middle, the latter having passing around it the main driving belt d', which
receives its motion from pulleys on the overhead shafting.
The vertical slide e, which determines the vertical position of the milling tool c³,
is raised and lowered by a swivelling rod e, having a hand wheel at its upper end,
and with its lower end c, which is screwed, passing through a screw box, formed
in a bracket extension of the saddle b, so that by rotating the said rod, the cutter is
raised clear of the path of the articles to be profiled or it is lowered into profiling
contact with them when the table is rotated.
The cutter is automatically brought up to the work and made to follow or trace
the outline of the former by the saddle with the vertical cutter carrying slide at its
front being constantly pulled forward in the direction of the arrow (see Figure 1)
by the weight, suspended from a cord f', passing over a pulley, supported by a
bracket a of the general fixed framing a, and being connected to the end of a
projection arm / 3, made fast to the rear of the saddle.
g is the rotating table, mounted upon an axis g', which turns within bearings of
the brackets a, a, and with the end 9, taking its thrust upon a bearing in the
bracket a, and with the topside of the said table carrying a plate g³, having
studs g', (see Figures 4, 5, 8 and 9) and work holders go, and whose edges are of
the exact outline as the former h, (see Figure 10) which is bolted to the underside
of the table, and with the roller , of the tracer or follower i, impinging upon the
slightly chamfered edges ', of it. The chamfering is for the purpose of bringing
the profiling back to truth on wear of the parts.
The table which carries the work j, is slowly rotated through the medium of a
tangent wheel k, bolted to the underside of it, and having intergearing with it, a
worm k, driven by a second worm wheel 2, mounted on a spindle and receiving
its motion from a worm on the shaft, supported in suitable bearings and
having at its outer end stepped pulley, around which a band k³, receiving its
motion from the stepped pulley de, below it passes.
The rod or shank i, of the tracing roller is carried within a sleeve bracket a', and
is adjustable therein by a collar or lock nut 22, at its front and a set screw ³, at the
back end, whilst the head or fore part, has an adjustment slide 2, whereby the
tracing roller can be adjusted on wear.
The table, which is tray shaped has an annular gutter m, formed within it,
having a drain or outlet m³, depending into a second annular gutter ³, with a
hanging spout n, directed from it through which the soap suds and oil employed
for lubricating and keeping the work cool is drained away from tlie táble.
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 :-
:-
First. In profiling or outline-shaping machines, carrying the milling or cutting
tool by a vertically moving slide carried by a traversing saddle or carrier having a
pulley over which a driving band taking round a pulley of the cutter spindle
passes, substantially as described and set forth in Figures 1 to 10.
Secondly. In profiling or outline-shaping machines, carrying the milling or
cutting tool by a vertically moving slide carried by a traversing saddle or carrier

page_text: and with the said tool and the tracing roller kept up to their work by a weight or
spring arranged to give a forward pull to the saddle, substantially as described and
set forth in Figures 1 to 10.
Thirdly. In profiling or outline shaping machines, the combination with the parts
referred to in the first claim, of a rotating work carrying table, substantially as
described and set forth in Figures 1 to 10.
Fourthly. In profiling or outline shaping machines, the combination with the parts
referred to in the second claim, of a rotating table, carrying a former or dummy
against the edges of which the said tracing roller or follower impinges and thereby
governs the position of the cutter relative to the work, substantially as described
and set forth in Figures 1 to 10.
Fifthly. In profiling or outline shaping machines, the combination with a rotating
work table carrying a former or dummy with inclined edges, of a chamfer-edged
follower or tracing roller, adjustably mounted upon a part of the traversing saddle,
substantially as described and set forth.
Sixthly. In profiling or outline-shaping machines, the general construction,
arrangement and combination of the parts, less the driving gear and motion
communicating means, substantially as described and set forth in Figures 1 to 10.
Seventhly. The general construction, arrangement and combination of the whole
of the parts of profiling or outline-shaping machines, substantially as described and
set forth in Figures 1 to 10.
