APPARATUS FOR ROSE TURNING AND SHAPING
Year: 1885

page_text: I, GEORGE WILLIAM BUDD of 127 Long Acre in the County of Middlesex
Engineer do hereby declare the nature of my invention for APPARATUS FOR ROSE
TURNING AND SHAPING to be as follows.—
This invention has for its object the production of ornamental forms and shapes
similar to those usually produced by the so called 'pumping motion' of the Rose
Engine by a piece of apparatus placed on an ordinary lathe, or that can be used as
a separate shaping machine with the addition of suitable driving gear In order to
do this, I place on the front of the lathe head a collar or plate somewhat similar to
that used for the ordinary form of the oval chuck, but instead of having a plain
ring only, it has also a fitting to carry the Rosette or Rosettes the pattern of which
it is desired to produce on the work, and which rosettes may have their patterns
either on their face or edge This fitting may be either a plain one or it may have
a tangent screw or other suitable adjustment to place the rosettes in any desired
position. The Collar has a central aperture through which the nose of the mandrel
projects, that the second part of the apparatus, the chuck, may be attached to it
The Chuck consists of two parallel plates, one of which, the back plate, has on
one side of it a boss into which is tapped the screw for its attachment to the lathe
mandrel, and the other plate has on its front side a turret which has a fitting to
carry a moveable part that carries the false nose on which is placed the work to be
operated upon, or I attach to the front of the moveable piece a worm wheel and
tangent screw such as is at present used upon the various ornamental chucks. The
fitting is preferably cylindrical and the moveable piece is prevented from rotating
in the fitting in the turret, by suitable means but it is free to move in and out
under the guidance of the templates or rosettes placed on the collar as before
described, and when thrust out is brought back to its original position by means of
springs or other suitable mechanism-By another arrangement I use springs or
suitable mechanism to bring the moveable piece back to its original position
whether it is thrust out or drawn in In order to cause this movement, I inlay in
or attach to either the front or back plate, a bar which is capable of sliding in the
direction of its length, and which is caused so to slide by the engagement of a
rubber or roller, which is attached to it, with the rosette or rosettes. This rubber
or roller is placed on a post which projects at the back of the chuck and is con-
trolled in a slide in the bar by a screw having a decimal thread and a micrometer,

page_text: by means of which it is placed in its desired position and fixed there by a clamping
screw It has also in connection with it a screw with a decimal thread and a
micrometer for 'stopping out' part of the wave of the rosette To the end of the
bar opposite the roller or rubber I attach a spring or by some other suitable means
I cause the roller or rubber to be kept in constant contact with the rosette and the
bar consequently slides to an fro according to the waves on the template or rosette,
as the chuck is rotated with the lathe mandrel Sometimes I duplicate the above
arrangement of rubbers or rollers and springs, that is I use a pair of rubbers or
rollers and their screws, one at each end of the bar and a spring also at each end-
By a system of levers or inclined planes, which may be made adjustable, or by any
other suitable means, any movement of the bar is conveyed to the moveable piece
in the turret, so that while the movement of the bar is at right angles to the
mandrel, the movement of the front piece is at right angles to that of the bar and
I can produce either copies or reversed copies of the rosette or rosettes, and also
I can make the waves either copies or more concave or convex than those of the
rosette The two plates of the chuck are kept parallel and in position with each
other by two steel slides, as in the ordinary ornamental chucks, attached to either
the front or back plate, and a suitable screw with a decimal thread and micrometer
& nut give the necessary movement for producing Eccentric Rose turning, while
by giving the Rosette any desired amount of eccentricity by means of the fixing
screws on the collar, and allowing the front slide to move the chuck will produce
Oval Rose work also-though this may be assisted by the addition of a pair of
pallets working on the plain part of the collar if necessary-By another arrange-
ment I omit one of the plates, and place the boss and tuirct one on each side of a
single plate, but the chuck will then produce merely copies or reversed copies of
the rosette or rosettes.

page_text: I, GEORGE WILLIAM BUDD of 127 Long Acre in the County of Middlesex
Engineer do hereby declare the nature of my invention for APPARATus for Rose
TURNING AND SHAPING and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement
-
This invention has for its object the production of ornamental forms & shapes
similar to those usually produced by the so called "Pumping Motion" of the Rose
Engine and by apparatus added to lathes with traversing mandrels-In each of
these cases the mandrel is " traversing" or capable of endlong movement, generally
used for screw cutting, with a short steel screw guide, and the mandrel together
with the work attached to it is caused to oscillate in and out, in its bearings, that
18, in the direction of its line of centre by means of rosettes or templates attached
to the end usually occupied by the screw guides, in the case of a lathe or attached
to a drum in the Rose Engine-Suitable rubbers and rollers being added and
springs for the purpose of causing the rubbers or rollers and rosettes being always
kept in contact The lathe pulley being rotated causes the mandrel with its various
chucks, work etc so to oscillate that a tool which may be either stationary or
revolving will reproduce on the face or edge of the work an exact copy of the
rosette used
In order to produce this work I place a suitable piece of apparatus which I call
a "Rose Engine chuck with pumping motion" on the lathe mandrel, and as the
mandrel is in this case not required to oscillate, my apparatus is equally suitable to
all lathes, whether traversing or otherwise
With the addition of suitable driving gear my apparatus may be used as a
separate shaping machine, that is to say, The apparatus as described may be
mounted on a spindle or mandrel, placed horizontally or vertically, either ten-
porarily or permanently, in suitable bearings, supported by a framework to which
the collar, in my 4th claim mentioned and its appliances may be attached-Or the
apparatus may be mounted on the spindle provided in a universal shaping machine
(sometimes called a steam arm) for giving a circular movement to the work, or on
the bed plate, either of which arrangements will constitute a shaping machine
suitable for doing the same kind of work as that accomplished by my chuck when
placed on the lathe mandrel, excepting that much heavier work in wood and metal
can be produced, owing to the greater strength of the machine and the facility for
applying the traversing (or stationary) revolving cutting or milling tools, and the
machine so constituted can be driven by belts or gearing & by steam or any
convenient motive power
The instrument consists of two parts firstly, the Ring or collar and secondly the
Body or Chuck-The parts will be described hereafter in the above order and
reference to the drawings (in which like letters represent like parts) will help to
explain the construction of my invention
Figure 1 is a horizontal section of the collar and chuck in combination as used-
Figure 2 is a plan of the chuck, showing dotted in k, the method of placing the

page_text: pallets for use in oval turning-Figure 3 is a section shewing the construction of
the central bearing and the adjustable plane for giving the pumping motion to the
chuck, and Figure 4 is a plan of the collar shewing the Tangent screw movement
applied to the Rosette
For shortness I use the word "Rosette" alone throughout to mean rosette or
template
Firstly, The Collar is a metal plate attached to the front of the lathe head X
Figs 1 & 4, and is similar generally to that used for the ordinary oval chuck. It
has a central aperture of convenient shape through which the nose of the mandrel
projects, enclosed by a turned fitting upon which revolves a boss, consisting of a
tangent wheel of a convenient number of threads to its worm & suitably figured
(a in fig 1) to which is attached a plain circular piece (b in fig 1) that serves as a
guide for the pallets in oval turning, and on the front of this is placed the rosette
(c in figs 1 & 4) which is retained in its place by means of a pin and a screwed
ring (din figs 1 & 4). The Tangent screw which gears into the tangent wheel is
shewn in Fig 4 in a carriage and is placed, in this case, at the side, with a
reader (6 in fig 4) at the top, though these may of course be placed at any part of
its circumference most convenient of access. The collar has also two screws placed
through the projecting bosses (as described in my Specification N° 5570 of 1885,
and as in the usual oval chuck collars) for accurately adjusting it to any desired
degree of eccentricity and there fixing it
grooves
Secondly, The Chuck, (Figs 1, 2 & 3), consists of two plates, a convenient form
of which is shewn in the plan fig 2, and to the back of the lower or back
plate (g' in fig 1) is attached a boss tapped to receive the nose of the mandrel (f in
fig 1) and on its face it carries the front or upper plate (g in figs 1 & 2) To the
back of this plate g, and not to the back plate as erroneously suggested as an
alternative in my Provisional Specification, are attached a pair of steel slides,
similar to those of the usual oval and eccentric chucks, which are shewn dotted
in h in fig 2 The movements of this plate g, are controlled for eccentric turning
by the screw & in fig 1 (of a decimal thread and a micrometer) and its nut 7 in
fig 1, and for oval turning by means of the adjustable pallets shewn dotted in k k,
figs 1 & 2, the corresponding pallets being omitted in each case to shew the
remainder of the chuck more clearly These pallets are kept in position by means
of the screws 1 figs 1 & 2 (shewn dotted) and are kept parallel by means of
เ
planed out in the steel slides, which have several tapped holes that the pallets may
be placed in various positions if desired-The foregoing shews the adaptability of
the chuck as a combined oval & eccentric chuck, and in order to place the rose
ornament on the works produced by it, I inlay or attach to the front plate a steel
bar (m in figs. 1, 2, & 3) so that it is capable only of motion in the direction of its
length which motion is given to it by the engagement of the roller (n in fig 1)
with the rosette (c in fig 1) The support (n¹ fig 1) of the roller projects through
the two plates. In the drawings a roller is shewn, but at times I employ rubbers
of various materials and shapes, and for the convenience of description the term
"roller" implies throughout a "rubber or roller" The standard or support on
which the roller is placed has a nut which engages with the screw (of a decimal
thread and its micrometer) p in fig 1, and by its means the roller is placed in its
desired position, whilst it is kept in contact with the rosette by means of the
spring attached to the bar (r in fig 1,) for the regulation of the tension of which
provision is made as shewn At the same end of the bar as the adjusting screw 18
also placed a "stop screw for similar purposes and of a similar construction to
that described in my specification No 5570 of 1885 At the opposite end of the
bar (left hand in fig 1) is placed a screw of a decimal thread with a micro-
meter (s figs 1 & 2) that has a nut (t in fig 1) to which is attached a long
lever (u in fig 1) and a short lever (v in fig 1) the face of the latter being in
contact with the roller win figs 1 & 3-The use of this combination is as follows,
In the present instance, as shewn in the drawing, when the roller is in contact
with the rosette, at the lowest point of 'the pattern and the lever v, which becomes
"

page_text: an inclined plane, is in contact with the roller w, the chuck being rotated until the
roller n comes to the highest point of the rosette, the bar will have received a
certain amount of endlong movement, which will have caused the inclined plane v
to advance a similar amount and will consequently have caused the steel cylinder
(x figs 1 & 3) to which the roller w is attached (as shewn in figs 1 & 3) to have
been pushed out a certain distance, which is determined by the inclination of the
adjustable plane v, similarly if the nut (t) is advanced by means of the screw 8, 80
that the inclination of the plane is reversed, that is, it inclines from right to left,
the advance given to the bar will cause the steel cylinder (a) to be depressed-By
means of this screw adjustment I am enabled either to copy or reverse the pattern
of the rosette, and also to make the waves on the work a copy as to convexity or
concavity or by placing the plane at a suitable angle to make them more or less
concave or convex at pleasure The guidance and control of the pumping part of
the chuck will be clearly perceived on reference to the drawing Fig 1 A and B
are two turrets preferably circular placed on the front plate of the chuck. B has
a steel collar or lining in which the steel cylinder a works, to which is attached
the front plate C, carrying the false nose for the attachment of the work to bo
ornamented D is a plain hollow cylinder, of which one end is attached to the
plate C, and to the other end of which is fixed a ring E, the purpose of which 15,
that when the cylinder is depressed the spring F may cause it, (on being relieved
of the pressure of the roller w) to recover its original position, whilst to the top of
the turret B is attached another ring G, which for a similar reason acts on the
spring H to bring it back again when thrust out The base of the steel cylinder x
18 shaped as shewn in figs 1 & 3 for the support of the roller w, and also to allow
it to receive the necessary motions without coming in contact with the steel bar
which is shaped out as shewn in fig 3 to allow it to clear in working The whole
of the oscillating part of the chuck is prevented from rotating in the Turrets by
pins or slides and it, (that is, the above described combination) can only rotate with
the rest of the chuck, whilst its oscillations are quite independent of the movements
of the slide g, and are caused as described, by the pattern of the rosette. By
another arrangement I omit the tangent wheel and screw from the collar altogether
and place them on the front of the plate C, fig 1, which then becomes a plain plate,
the nose being carried on the front of the tangent wheel, as in the usual ornamental
chucks
Another variation of the construction of my chuck, and one that I shall
occasionally employ, is to place an additional plate between the two plates (shewn
in perspective in fig 5) in the drawing, in which case the middle plate will have a
pair of slides on each of its faces so that while the middle and back plates, with
the addition of pallets, will act as an ordinary oval chuck, without the necessity of
adjusting the pallets as in the present arrangement, before mentioned, the front
and middle plates will, having the parts shewn in the drawing, act as an eccentric
chuck, and it will then be unnecessary to remove the coupling piece of the screw (2)
when using the oval and eccentric in combination, as it is in the present con-
struction. This arrangement with the addition of a suitable means of adjusting
the oval and eccentric parts of the chuck at various angles to each other, is
somewhat similar to the oval and eccentric compound chuck, of ordinary con-
struction, and I do not claim it, except in combination with the rose engine
pamping movement of my chuck-Sometimes too I propose to omit the
eccentric slide of my chuck altogether, and use only the oval part of it, in
combination with the Rose Engine pumping movement, depending upon the
ordinary eccentric chuck for any oval and eccentric or occentric rose engine
turning.
”
The advantage of my collar and chuck as herein before described is, that not
only can they be placed on any lathe, but also it is possible to do without rosettes
having their patterns on their faces, and to use those having the patterns on their
edges, so that those used for this chuck can also be used for my Patent Chuck
(N° 5570 of 1885) and the Rose Cutting Frame, thereby avoiding the necessity of

page_text: having two or more sets of rosettes, a desirable result not before attained by means
of a chuck
Having now described the construction of my collar and chuck I will proceed to
shew its method of working-Firstly the collar is placed on the fiont of the lathe-
head and the rosette to be used is placed on the front of the collar and secured
The chuck is then placed on the mandrel, with the roller screwed well away to the
right, as in the drawing, if it is desired to reverse the rosette pattern, that is to
produce a concave from a convex form, the inclined plane is screwed to the position
shewn in the drawing, and the roller is screwed down on the rosette until the
rollers w and n are respectively in contact with the plane and the rosette, and if
to copy the pattern of the rosette, the same method obtains, with the plane inclined
in the opposite direction-If it is desired to ornament eccentric work, the necessary
amount of eccentricity is first given to the front plate, and the bar and its attach-
ments are then adjusted as above described. If Oval work is to be ornamented the
pallets are placed in position and adjusted, and the desired amount of eccentricity
given to the collar as is usual in the ordinary oval chuck, and the bar etc, is then
adjusted
I do not claim the following individual parts, except as applied to my apparatus,
viz, the worm wheel and tangent screw, nor the rosettes, nor the use of a rubber
oi roller working against them, nor the use of a stop screw, nor the eccentric, nor
the oval movements, and in my 4th claim I do not intend to claim the plate or
collar apart from the other mechanism claimed as used in combination therewith
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is "

above described of an apparatus (to be used on a lathe) for the production of solid
rose work

above described of an apparatus to be used apart from a lathe, as a shaping
machine

adjustable rubber or roller, spring and stop screw connected therewith substantially
as above described.
