WILLIAM LLOYD WISE of 46 Lincolns Inn Fields in the County of Middlesex
IMPROVED METHOD AND MACHINERY OR APPARATUS FOR POLISHING JEWELS, RINGS
AND SIMILAR OBJECTS "
(a communication from Jaime Tagell y Urell and José
Tagell' y Nogues, persons resident at Barcelona in the Kingdom of Spain) :
This invention has for object the polishing by machinery of jewels, rings,
brooches and similar objects of comparatively small dimensions usually polished
by hand.
For this purpose there is employed a machine that may be operated by foot, hand
or otherwise, and comprising an initial motive mechanism and various mechanisms
for transmitting and transforming the initial movement into a series of movements
suitable for the several operations to be performed, such as continuous movements
of rotation in opposite directions,-alternating rectilinear movement in all
directions-radiating from a given centre in a common plane; oscillating movements
on a horizontal axis,-and oscillating movements on a vertical axis.
The several mechanisms which make up this series are supported on a frame
mounted on a bed plate or table. In conjunction with them are used a series of
tools and interchangeable parts adapted to the machine and such as to allow of the
execution of a variety of polishing operations; which tools may be varied to suit
convenience and according to the work to be executed.
According to one arrangement a bed plate with which is cast the frame
supporting the mechanism employed to transmit and convert mechanical movement
is fixed on a table mounted on frame plates; below the table is the driving
ГР.... 31

page_text: arrangement comprising a treadle that through a rod actuates a crank pin fixed on
a pulley fly wheel; this forms one piece with a first motion toothed wheel, which
gears with an intermediate wheel driving three similar wheels, keyed on to the
shafts which carry suitable rotatory polishing tools, such as drums or circular brushes
suitably secured, for example by screwing direct to the ends of these shafts.
By means of a stud fixed in a sliding eccentric the wheel mounted on the upper
shaft communicates an adjustable alternating rectilinear movement to a sliding part
which may receive divers polishing tools in its length.
A hand wheel is keyed on the other extremity of the shaft thus enabling the
machine to be worked by hand when required.
A sliding eccentric is guided in the guide bars of a rotating frame the position of
which and consequently also the inclination of the tool may be varied at will by
means of two toothed wheels the upper one of which mounted on the end of a shaft
is worked by hand by means of a milled stud; this shaft and the frame are fixed
in position by pressure screws.
Supports for the oscillating or vibrating polishing organs which are operated by
one of the lower shafts are carried in a cast-iron frame fixed to the foundation
plate.
At the end of this shaft beyond the toothed wheel is keyed a sliding crank
which by a connecting rod communicates an alternate oscillating movement to
a sector jointed to the upper part of a support fixed to the frame or foundation
plate.
On the side of this sector is mounted a turning lever which may oscillate
between the sector and a slide guide in which a pressure screw enables the position
of the said lever to be fixed; a socket tool holder is provided in which is inserted
and fixed by set screws, a reed cut to the shape of a lance or a piece of white wood
or other suitable polisher which thus receives an oscillating movement on a
horizontal axis the range of which may readily be regulated on the one hand by
means of the sliding crank and on the other hand by the lengthening of the tool in
the socket.
Another oscillating tool the rotation of which however takes place on a vertical
axis is mounted in a separate socket support placed on the frame or foundation
plate and operates as follows:
In the interior of the frame the horizontal shaft to which the hand wheel is
attached actuates through a pair of toothed bevel wheels a vertical shaft which at
its lower end underneath the foundation plate carries a sliding crank provided with
a sort of sliding rod and suitable guides; this in its turn causes the oscillation of
the socket which is guided in the foundation plate and at the bottom of which the
guide piece is keyed.
In this socket and projecting above the foundation plate, is adjusted and fixed in
place by a set screw or otherwise à rod which may slide to any suitable heiglit and
also take up various angular positions.
The upper extremity of this rod is terminated, by a joint with fastening screw
in which a sector provided" with a suitable tool-holder is turned and fixed in
suitable inclined positions.
The said tool holder operates similarly to the one already described, though in a
different direction of oscillation.

It will be understood that 'the mechanism employed for the transmission and
conversion of mechanical movement as just described will allow of movements
being effected in such of the directions before summarised as may be desired and
which are analogous to those executed in polishing' by hand.

Among the accessories which may with advantage be used with machinery sueli
as above referred to may be mentioned
$10
1) A support or hand rest for the objects to be polished or burnished; this may
be placed at any convenient point on the foundation plate, the height being
regulated by an adjusting screw.
2) Various interchangeable parts or supports adapted to the forms of the objects

page_text: to be polished and which may be fixed on the before named support by means of a
cylindrical shank and a set screw.
The polishing tools and holders include
1st) a sort of crayon holder suitable to receive a slate-point as a polisher and
consisting of an attachment rod and cleft tube with tightening ring.
2nd) a wire holder, the mounting of which is similar to that of a fret saw, is
fixed by two projecting lugs in the vertical radial slide having rectilinear motion
and provided with stop screws; these wires are suitable for polishing corners and
cuttings out and are retained in the holder by means of a hook at one end and at
the other by a screw pincer which allows of their being tightened as desired
3rd) A framed support suitable for receiving appropriate tools for rectilinear
movement, cylinders for polishing rings, files etc; and operating in any direction in
the plane of the frame; direction maintained on change of direction it is desired to
communicate to the frame by means of a toothed wheel with stop screw; a socket
with stop screw receives the tools direct or those which are set in the tool holding
screw sockets.
4th) a kind of file consisting of a wooden core more or less bulged out in
section towards the outside and on the exterior of which is fixed emery paper or
cloth or any other tissue suitable for receiving a polishing substance of any kind
such as emery, tripoli powder, spanish white etc
5th) A rectilineally moving brush which is fixed in the sliding part.
6th) A rotatory brush with a screwed shank, to be screwed into the end of one
of the horizontal shafts.

These brushes are intended either for polishing or the removal of emery particles
which may remain in the hollow parts of the object to be operated on
-
7th) Parts of divers forms covered with skin, buff leather, etc, for burnishing, or
with emery cloth for polishing and which are also similarly screwed into the ends
of the horizontal shafts.
The operation of the machine is readily deduced from the above; it is clear also
that it may be actuated by pedal as above described, or by mechanical power
simply adapting loose and fast pulleys to one of the shafts of the machine.

WILLIAM LLOYD WISE of 46 Lincolns Inn Fields in the County of Middlesex
IMPROVED METHOD AND MACHINERY OR APPARATUS FOR POLISHING JEWELS, RINGS
AND SIMILAR OBJECTS (a communication. from Jaime Tagell y Urell and José
Tagell y Nogues persons resident at Barcelona, in the Kingdom of Spain)
This invention has for object the polishing by machinery of jewels, rings, brooches,
and similar objects of comparatively small dimensions usually polished by hand.
For this purpose there is employed a machine that may be operated by foot, hand
or otherwise, and which comprises an initial motive mechanism and various
mechanisms for transmitting and transforming the initial rotary movement into a
series of movements suitable for the several operations to be performed, such as
continuous movements of rotation in opposite directions.-alternating, rectilinear
movement in all directions radiating from a given centre in a common plane;
oscillating movements on a horizontal axis, and oscillating movements on a
vertical axis.
The several mechanisms which make up this series are supported on a frame
mounted on a bed plate or table. In conjunction with them are used a series of
tools and interchangeable parts adapted to the machine and such as to allow of the
execution of a variety of polishing operations; which tools may be varied to suit
convenience and according to the work to be executed.
Referring to the accompanying three sheets of illustrative drawings Fig 1 is an
end elevation and Fig 2 a side elevation of an arrangement of machine according
to this invention, the lower part of the frame work being omitted.
Figs 3 and 4 are respectively an end and a side elevation (to a smaller scale)
shewing the frame work for supporting the mechanism and the arrangement of
treadle and connecting rod for transmitting motion to the mechanism from the foot
of the operator.
Figs 5 to 23 inclusive illustrate various views of detail parts and accessories of
the machine.
A bed plate with which is cast the frame supporting the mechanism employed to
transmit and convert mechanical movement is fixed on a table mounted on frame
plates; below the table is the driving arrangement comprising a treadle that
through a rod actuates a crank pin A fixed on a pulley fly wheel B; this is in one
piece with a first motion toothed wheel B', which gears with an intermediate
wheel C driving three similar wheels D. E. F keyed on to three shafts U and M M
which carry suitable rotatory polishing tools, such as drums Y or circular brushes
suitably secured, for example by screwing direct to the ends of the shafts:
By means of a stud fixed in a sliding or adjustable eccentric (eccentrique à
.coulisse) G there is communicated from the wheel D mounted on the shaft U an
adjustable alternating rectilinear movement to a sliding part I which may receive
divers polishing tools in its length.
A hand wheel is keyed on the other extremity of the shaft U thus enabling the
machine to be worked by hand when required.
The sliding eccentric G is guided in the guide bars of a frame J capable of
rotation the position of which and consequently also the inclination of the tool may
be varied at will by means of two toothed wheels K2 K2 the upper one of which (K¹)
mounted on the end of a shaft K. is worked by hand by means of a milled head
this shaft K and the frame are fixed in position by set screws L L..
i

page_text: Supports P and C for the oscillating or vibrating polishing organs are carried in
a cast iron frame fixed to the foundation plate as shewn. At the end of the one
shaft M beyond the toothed wheel E is keyed an adjustable crank (manivelle à
coulisse) N which by a connecting rod communicates an alternate oscillating
movement to a sector O jointed to the upper part of the support P. On the side
of this sector is mounted a lever Q which can oscillate between the sector O and.a
slide guide R, a set screw S enables the position of the said lever to be fixed. The
lever terminates in a socket tool holder T, into which is inserted and fixed by set
screws, a reed cut to the shape of a lance, or a piece of white wood or other suitable
polisher which thus receives an oscillating movement on a horizonal axis the range
of which may readily be regulated, on the one hand, by means of the crank N, and,
on the other hand, by the lengthening of the tool in the socket. Another oscillating
tool the rotation of which however takes place, on a vertical axis is mounted in the
socket support C and operates as follows:
In the interior of the frame the shaft U actuates through the toothed bevelled
wheels V a vertical shaft X which at its lower end underneath the foundation plate
carries an adjustable crank Z provided with a sort of sliding rod guided in the
part A; this in its turn causes the oscillation of the socket C which is guided in
the foundation plate and at the bottom of which socket the guide piece A is keyed. In
the socket C above the foundation plate is adjusted, and fixed in place by a set
screw e or otherwise a rod d which can be adjusted to any suitable height and
angular position. The upper extremity of the rod d is terminated by a joint with
set screw whereby a sector f provided with a suitable tool-holder T can be adjusted
to various inclined positions.. The said tool holder operates similarly to the one
already described, though in a different direction of oscillation.
It will be understood that the mechanism employed for the transmission and
conversion of mechanical movement as just described will allow of movements being
effected in such of the directions before summarised as may be desired and which
are analogous to those executed in polishing by hand.
Having thus explained the means of operating the tools, I proceed to describe
the accessories illustrated in Figs 6 to 23 inclusive.
Figs 6, 7 and 8 are respectively front and side elevation and plan of the support
or rest for the objects to be polished or burnished. This support or rest may to
this end be placed on the foundation plate at any point convenient for the easy
polishing of the objects. It is adjustable to any height by an adjusting screw as
shewn.
Figs 9 to 14 are detail views of various interchangeable parts or supports which
may be varied according to the forms of the objects to be polished and which may
be fixed at r on the support, Fig 7, by means of their cylindrical shanks and a set
screw.
.
The polishing tools and holder include the following
1) a sort of crayon holder, illustrated in Fig 15, and suitable to receive a slate-
point as a polisher and consisting of an attachment rod and a cleft tube with
tightening ring.
2) a wire holder, illustrated in Fig 16, the mounting of which (similar to that of
a fret saw) is fixed by two projecting lugs in the slide I. The slide I has rectilinear
motion and is provided with set screws; these wires are suitable for polishing
corners and cuttings out and are retained in the holder by means of a hook at one
end, and at the other by a screw pincer which allows of their being tightened as
desired.
3) a framed support, illustrated in Fig 17, suitable for receiving appropriate tools
for rectilinear movement, cylinders for polishing rings, files etc; and operating in
any direction in the plane of the frame, the direction being maintained (after
setting in any direction it is desired to give to the frame) by means of a toothed
wheel with stop screw; a socket with set screw receives the tools direct or set in
the tool holding screw sockets
4) a kind of file, illustrated in Fig 18, consisting of a wooden core more or less

page_text: bulged out in section towards the outside and on the exterior of which is fixed
emery paper or cloth or any other tissue suitable for receiving a polishing substance
of any kind such as emery, tripoli powder, spanish white, etc.

5) a rectilineally moving brush (illustrated in Fig 19) which is fixed in the part I
(Figs 1 and 2).
6) a rotatory brush with a screwed shank, to be screwed into the end of one of
the horizontal shafts M..
These brushes are intended either for polishing or the removal of emery particles
which may remain in the hollow parts of the object operated on.
7) parts of divers forms (illustrated in Figs 21, 22 and 23) covered with skin,
wash leather, etc, for burnishing, or with emery cloth for polishing and which are
also screwed into the ends of the shafts M M similarly to the brush represented in
Fig 20.
The operation of the machine will be readily understood from the above description;
it is clear also that instead of being actuated by pedal as shown in the drawings it
may be worked by motor by the use of loose and fast pulleys adapted to one of the
shafts of the machine.
Having now described the nature of the said invention and the manner of
carrying it into practical effect as communicated to me as aforesaid, I would have
it understood that what is claimed as secured to me under the Letters Patent first
hereinabove in part recited is;
1 Polishing jewels and similar objects by the use of machinery constructed
arranged and operating substantially as hereinabove described with reference to the
accompanying drawings.
2 The combination in a machine for polishing jewels and similar objects of
adjustable mechanism for imparting to appropriate operating tools such as herein-
above referred to (a) continuous rotary movement (b) alternating rectilinear
movement with adjustable travel (c) oscillatory movement on a horizontal axis, and
(d) oscillatory movement on a vertical axis, all substantially as described, the
articles operated upon being held by suitable supports or holders as hereinabove set
forth.

In Witness whereof I the said William Lloyd Wise have hereunto set my
hand and seal this thirteenth day of June in the year of our Lord one
thousand eight hundred and eighty, three.
