PROVISIONAL SPECIFICATION.
Improvements in Wine Glasses and in Apparatus for Forming
Certain Parts of the same.
I, JAMES MURDOCH NAPIER of York Road, Lambeth, Mechanical Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object improvements of that kind of wine glass which
has no foot or base but has a handle or long stem formed with it or attached to a
short stem formed with it in the centre at the bottom of the wine glass. Such wine
glasses are supported in a stand or holder around a circular opening having a
sufficient portion of its circumference removed so as to permit of the free passage of
the part of the stem or handle which is near to the bottom of the wine glass or, as
the case may be, of the neck of the handle and the attachment to the stem of the
wine glass when it is to be placed on its seat in the holder or taken from it. See
the Specifications of my Patents dated and numbered respectively 11th March 1865,
No. 693 and 13th September 1867, No. 2595.
I provide my improved wine glasses with a circular projection or button formed
round the stem at the bottom of the wine glass. The diameter of this projection or
button is arranged to conform to that of the circular opening in the stand or holder
around which is the seat for the wine glass in such manner that the projection or
button on the bottom of the wine glass will fit into the opening allowing only sufficient
play so that the wine glass can be placed on its seat and removed with facility.
The edge of the projection or button being rounded it will be found that a small
amount of play only is necessary, between the projection or button and the seat
opening, to afford the necessary freedom for the ready removal of the wine glass
and its replacement. The importance of the proper adjustment of the diameters of
the seat openings in the stands or holders with that of the projections or buttons
on the bottom of the wine glasses is considerable as it affects the centreing of the
wine glass in its seat as well as stability when placed on its seat, for the last
purpose it is also most important that that part of the bottom of the wine glass
immediately around the projections or buttons should be formed truce so that when
resting on its seat the wine glass and its stem or handle may not only be seated
firmly but also truly in all senses in the stand or holder.
The results in these respects did not prove satisfactory with wine glasses formed
in the manner indicated in the Specifications of my Patents above referred to in
which there is no projection or button provided on the bottom of the wine glass
arranged to fit the seat opening in the stand or holder.
The projection or button referred to may be formed along with the stem in glass
on or at the bottom of the wine glass or when the manner of attaching the handle
permits, it may be formed in metal or other suitable material and cemented to the
bottom of the wine glass and round the root of the glass stemn the stem passing
through it, the bottom of the wine glass round the stem and the stem itself having
been prepared true and of suitable form to receive it.
The projection or button referred to may also be made in one piece with the cup
or socket which when cemented to the glass stem of the wine glass serves through
its metal stem to attach the handle to the wine glass. Instead of making the cup
or socket just referred to of the coned or tapered form shown in my Patent
No. 2595, 1867, I make it cylindrical or nearly so but with the lip or mouth
rounded over outwards and I prepare the glass stem of the wine glass cylindrical in
form to fit it the rounding over of the lip or mouth of the cup or socket allowing
place for a small strengthening hollow to be left where the cylindrical stem meets

page_text: the guiding projection 'or button on the bottom of the wine glass. The cylindrical
form of the glass stem and of the cup or socket enable the cementing of the one
into the other to be more securely effected. I manufacture the cup or socket and
its metal stem which in my Patent No. 2595, 1867 are shown formed in one piece
in two distinct and separate parts formed so that by a simple process they can be
united or fastened together. In the manufacture of the cups or sockets I cut the
blanks from thin rolled ductile metal such as copper and force and form them into
the required shape with suitable tools. When the cup or socket is fully formed to
shape I punch a central hole in its bottom part of the size of the metal stem which
is to be passed through the hole and attached to it.
These metal stems may be manufactured from wire or rod, carefully drawn to
size in the usual way.
The wire so prepared is cut into lengths each length being sufficient for one stem.
Each length is put into a die tool when by the action of a punch a head is formed at one
end of the length. The diameter of this head is regulated so that it will pass into the cup
or socket freely until near the bottom, where the cup or socket has been left slightly
smaller for the relief of the punch which formed it, so that when the head is forced to the
bottom of the cup or socket and expanded to take its shape by means of a suitable
die tool and punch the cup or socket and the stem become thoroughly fastened
together. If preferred they may be soldered together. Before however carrying
out the process of fastening them together it may be found convenient to form the
other end of the stem to the required shape for being held by a split-tube-spring
screw or otherwise for attaching the handle. In preparing the stem to be held for
attachment to the handle by a split-tube-spring such as I have shown in my Patent
No. 2595, 1867, instead of providing it with a groove or notch into which the ends
of the split tube, which are slightly curved inwards, spring after having been forced
open by the end of the stem as illustrated and described in my Patent just referred to
I form it with a holding incline or cone against which the spring being always
partly extended while on the incline never ceases to operate as long as the stem is
in position the action of the spring's three parts or tongues against the incline or
cone of the stem always operating to draw the stem inwards and keep it firmly
home that is keeping the bottom of the cup or socket to which the stem is fastened
firmly held against the top of the split-tube-spring or against the top of the handle
or part attached to it in which the spring is fixed. It will therefore be understood
that I make the holding incline on the stem of sufficient inclination or cone so that
the action of the spring against it in its three parts will keep the metal stem of the
wine glass firmly against its stop as just explained and so therefore firmly held in
the handle to which the split-tube-spring is attached.
I make the holding incline or cone provided on the stem of a length to allow for
irregularities.in the manufacture in the length of the springs and in the position of
the holding incline or cone on the stem in relation to the bottom of the cup or
socket.
In order to prepare the split-tube-spring for being attached in a more convenient
manner in connection with the wine glass handle fix upon it a ring formed of a
short piece of tube which fits the outside diameter of the tube spring while its
length covers the short part of the tube spring at the top end which is not split.
This ring which I may call the intermediate ring is put on the tube spring so as to
be exactly flush with its top end. I further fix to the intermediate ring a casing or
covering tube which fits over the ring the one end being placed flusli with the top
end of the tube spring and of the intermediate ring.
The casing or covering tube may extend downwards so as nearly or wholly to
cover the tube-spring or to any convenient length beyond the tube-spring for the
attachment of the handls, the space left between the interior of the casing tube
and the tube-spring, amounting as it does to the thickness of the intermediate ring,
allowing free room for the opening of the tube-spring when the metal stem of the
wine glass is pushed into it. In this arrangement I make the upper part of the

page_text: casing tube to form a neck part between the bottom of the cup or SOCKET REENCHE
to the wine glass and the handle proper into which the lower part of the casing
tube is fixed. The length of the casing tube which projects from the handle is
regulated so as to allow sufficient length of neck in addition to that of the cup or
socket that together there may be enough length of neck to permit of the wine
glass being removed and replaced in its seat in the stand or holder by the user with
the facility desired. With this object also I make the diameters of the cylindrical
part of the cup or socket of the wine glass and of the casing tube attached to the
handle to coincide and leave at their junction an even surface without step or
irregularity which might catch against the sides of the opening through which the
neck has to pass when the wine glass is removed from or replaced on its seat in the
stand or holder. I prefer to make the casing tube to project from the handle
sufficiently to allow also of the placing of a small half rounded ring upon it just
above the handle proper. This ring may serve as a stop to give the distance which
the casing tube should project from the handle to afford the desired length of neck
as before explained. It will also cover the joining of the casing tube with the
handle and give finish to the work.
A casing tube such as I have described above may be employed when the split-
tube-spring is replaced by a socket with a screw thread within it to receive a stem
with a corresponding screw upon the wine glass or where the fastening together of
the parts is effected by other means.
In order that the handles of the wine glasses may be held by the user with
greater ease and convenience and not be liable to shift or slip downwards in the
hand but that although lightly and freely held or with little effort and attention the
wine glass may nevertheless retain its position with respect to its distance from
the hand so as to leave free room or clear length of neck for placing the wine glass
on its seat in the stand or holder; in order also that when the wine glass is to be,
removed from the stand or holder the user may be caused more readily to take hold
of the handle at a convenient distance from the seat of the wine glass so as to
perinit of the raising of the wine glass clear of its seat and the withdrawing it from
the stand or holder without the hand coming into contact with the ends of the seat
opening in the stand or holder, 1 form the handles of the wine glasses with pro-
jecting part or parts or of parts of varying diameters and forms arranged suitably
to effect the objects above explained.
I have stated with reference to the projections or buttons formed on my improved
wine glasses for the purpose of centering and steadying them when placed in the
stand or holder as well as with reference to the part surrounding the button or
projection upon which part the wine glass rests when placed on its seat in its stand or
holder and the short glass stem projecting from the bottom of the wine glass that they
should be accurately formed and central with the wine glass and seeing that in the
ordinary manufacture this result is difficult of attainment to the point of accuracy
desirable I provide special apparatus for grinding the projection or button on the
bottom of the wine glass, the part of the bottom of the wine glass round it where it
rests on its seat in the stand or holder as well as the short stein when such is used
to which the cup or socket is fitted and cemented also in the case when the button
is formed in metal or other material and cemented to the bottom of the wine glass
to grind the wine glass to receive it and when the projection or button is formed in
one piece with the cup or socket to grind the glass round the short stem, when such
stem is provided, as well as the short stem itself, ready to receive the cup or socket
and the projection or button combined. In this apparatus 1 use the ordinary
grinding and finishing wheels of suitable form fixed on running spindles. The wine
glass is centered and held in a centering case consisting of a circular base plate
with boss rising in the centre terminating at the top in a female or male centre, this
boss is bored up nearly its full height with a cylindrical hole so that when placed
upon a pin fitting the hole it will turn truly. Over the outside of this boss reaching
down nearly to the base plate is a tubular piece closed at the top end where in the
centre is placed a pointed screw to rest in the female centre in the boss below. On

page_text: the point of this screw the tubular picce is supported and turns and moves freely.
At the bottom of the tubular piece near the base plate is fixed a circular platform
on which is placed a flat ring of india rubber leather or other suitable material for
the edge of the wine glass to rest upon while another ring of india rubber leather
or other suitable material of the internal diameter of the mouth of the wine glass
and with a hole fitting the tubular piece is put on to it and brought down to rest
upon the ring already placed on the platform being also of smaller diameter than
the ring on which it rests.
Thus while the wine glass rests on its edge on the lower flat ring it is centered
by the circumference of the upper ring which passes into it. There is a ring of
metal fixed to the base plate. -it rises up around the platform leaving a sufficient
clear space between. This ring is screwed to fit a cap or covering case which
encircles the wine glass and which is provided with an internal ledge at the top
which comes against a metal ring with leather or other suitable lining and formed
to suit the outer rounded portion of the bottom of the glass when the casing is
screwed down to fix the wine glass. Thus the wine glass is held central. The
grinding apparatus is provided with a lever or its equivalent adjustable by screws
and stops which is free to be vibrated on its axis; at the end of this lever is a pin
which fits the hole in the central boss of the centering case which can be turned
round when placed upon the pin of the lever. The adjustments applied to the
lever having been arranged to suit the position of the wine glass in respect to the
grinding wheel the glass is brought against the wheel with the greatest facility and
accuracy and as, with the centering case, it can be turned round on the pin on the
end of the lever while the operation of grinding is being performed it can be
ground truly, a stop against which the lever arrives being adjusted for the
diameter of the parts. By means of the apparatus above described I am enabled
not only to secure accuracy in the formation of the parts referred to but great
economy in the execution of the work.

COMPLETE SPECIFICATION.
Improvements in Wine Glasses and in Apparatus for Forming
Certain Parts of the same.
I, JAMES MURDOCH NAPIER of York Road, Lambeth, 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:-
This invention has for its object improvements in that kind of wine glass which
has no foot or base but has a handle or long stem formed with it or attached to a
short stem formed with it in the centre at the bottom of the wine glass. Such wine
glasses are supported in a stand or holder around a circular opening having a
sufficient portion of its circumference removed so as to permit of the free passage
of the part of the stem or handle which is near to the bottom of the wine glass or,
as the case may be, of the neck of the handle and the attachment to the stein of
the wine glass when it is to be placed on its seat in the holder or taken from it. Sec
the Specifications of my Patents dated and numbered respectively 11th March 1865,
No. 693 and 13th September 1867, No. 2595.
I provide my improved wine glasses with a circular projection or button formed
round the stem at the bottom of the wine glass. The diameter of this projection or
button is arranged to conform to that of the circular opening in the stand or holder
around which is the seat for the wine glass in such manner that the projection or
button on the bottom of the wine glass will fit into the opening allowing only
sufficient play so that the wine glass can be placed on its seat and removed with
facility. The edge of the projection or button being rounded it will be found that

page_text: a small amount of play only is necessary, between the projection or button and the
seat opening, to afford the necessary freedom for the ready removal of the wine
glass and its replacement The importance of the proper adjustment of the
diameters of the seat openings in the stands or holders with that of the projections
or buttons on the bottom of the wine glasses is considerable as it affects the centering
of the wine glass in its seat as well as stability when placed on its scat, for the last
purpose it is also most important that that part of the bottom of the wine glass
immediately around the projections or buttons should be formed true so that when
resting on its seat the wine glass and its stem or handle may not only be seated
firmly but also truly in all senses in the stand or holder.
The results in these respects did not prove satisfactory with wine glasses formed
in the manner indicated in the Specifications of my Patents above referred to in
which there is no projection or button provided on the bottom of the wine glass
arranged to fit the seat opening in the stand or holder.
The projection or button referred to may be formed along with the stem in glass
on or at the bottom of the wine glass or when the manner of attaching the handle
permits, it may be formed in metal or other suitable material and cemented to the
bottom of the wine glass and round the root of the glass stem the stem passing
through it, the bottom of the wine glass round the stem and the stem itself having
been prepared true and of suitable form to receive it.
In Figure 1A indicates my improved wine glass with a circular projection or
button a, formed round the stem at the bottom of the wine glass. The edge of
the button a at a' is rounded to facilitate the removing and replacing of the wine
glass in its seat in the stand or holder while its diameter is also arranged to suit the
seat as explained above. In this figure the projection or button is shown formed
along with the stem in glass.
In Figure 2 the button a which is shown in section is formed in metal or other
suitable material cemented to the bottom of the wine glass A and round the root
of the glass stem which has been prepared true and of suitable form to
receive it.
The projection or button referred to may also be made in one piece with the cup
or socket which when cemented to the glass stem of the wine glass serves through
its metal stem to attach the handle to the wine glass.
Figure 3 shows the button a made in one piece with the cup or socket c and
cemented to the glass stem and to the bottom of the wine glass A. d is the metal
stem through which the handle may be attached to the wine glass.
Instead of making the cup or socket just referred to of the coned or tapered form
shown in my Patent No. 2595, 1867, I make it cylindrical or nearly so but with
the lip or mouth rounded over outwards and I prepare the glass stem of the wine
glass cylindrical in form to fit it the rounding over of the lip or mouth of the cup
or socket allowing place for a small strengthening hollow to be left where the
cylindrical stem meets the guiding projection or button on the bottom of the wine
glass. The cylindrical form of the glass stem and of the cup or socket enable the
cementing of the one into the other to be more securely effected.
In Figure 4 the cup or socket e is shown attached to the glass stem at the bottom
of the wine glass as in my Patent of 1867 already referred to but in the present
improvement the socket is showu not coned or tapered but cylindrical and with a
rounded lip or mouth to fit into which the glass stem is prepared and cemented.
1 manufacture the cup or socket and its metal sten which in my Patent
No. 2595, 1867 are shown formed in one piece in two distinct and separate parts
formed so that by a simple process they can be united or fastened together. In
the manufacture of the cups or sockets I cut the blanks from thin rolled ductile
metal such as copper and force and form them into the required shape with
suitable tools. When the cup or socket is fully formed to shape I punch a central
hole in its bottom part of the size of the metal stem which is to be passed through
the hole and attached to it:

page_text: These metal stems may be manufactured from wire or rod carefully drawn to
size in the usual way.
The wire so prepared is cut into lengths each length being sufficient for one
stem. Each length is put into a die tool when by the action of a punch a head is
formed at one end of the length. The diameter of this head is regulated so that it
will pass into the cup or socket freely until near the bottom, where the cup or
socket has been left slightly smaller for the relief of the punch which formed it, so
that when the head is forced to the bottom of the cup or socket and expanded to
take its shape by means of a suitable die tool and punch the cup or socket and the
stem become thoroughly fastened together. If preferred they may be soldered
together. Before however carrying out the process of fastening them together it
may be found convenient to form the other end of the stem to the required shape
for being held by a split-tube-spring screw or otherwise for attaching the handle.
In preparing the stem to be held for attachment to the handle by a split-tube-spring
such as I have shown in my Patent No. 2595, 1867, instead of providing it with a
groove or notch into which the ends of the split tube, which are slightly curved
inwards, spring after having been forced open by the end of the stem as illustrated
and described in my l'atent just referred to I form it with a holding incline or cone
against which the spring being always partly extended while on the incline never
ceases to operate as long as the stem is in position the action of the spring's three
parts or tongues against the incline or cone of the stem always operating to draw
the stem inwards and keep it firmly home; that is keeping the bottom of the cup or
socket to which the stem is fastened firmly held against the top of the split-tube-
spring or against the top of the handle or part attached to it in which the spring is
fixed. It will therefore be understood that I make the holding incline on the stem
of sufficient inclination or cone so that the action of the spring against it in its
three parts will keep the metal stem of the wine glass firmly against its stop as just
explained and so therefore firmly held in the handle to which the split-tube-spring
is attached.
I make the holding incline or cone provided on the stem of a length to allow
for irregularities in the manufacture in the length of the springs and in the position
of the holding incline or cone on the stem in relation to the bottom of the cup or
socket.
Figures and 6 shew in section and plan to an enlarged scale the cup or socket c
formed as a separate piece and Figure 7 represents the metal stein d also formed as
a separate piece prepared for being fastened into the cup or socket while the other
end is formed for being held by a split tube spring for attaching the handle.
In Figure & the cup c and the stem are shewn united as also in Figure 9 in
which the stem d' is shewn screwed for the attachment of the handle.
In order to prepare the split-tube-spring for being attached in a more convenient
manner in connection with the wine glass handle I fix upon it a ring formed of a
short piece of tube which fits the outside diameter of the tube spring while its
length covers the short part of the tube spring at the top end which is not split.
This ring which I may call the intermediate ring is put on the tube spring so as to
be exactly flush with its top end. I further fix to the intermediate ring a casing or
covering tube which fits over the ring the one end being placed flush with the top
end of the tube spring and of the intermediate ring.
The casing or covering tube may extend downwards so as nearly or wholly to
cover the tube-spring or to any convenient length beyond the tube-spring for the
attachment of the handle, the space left between the interior of the casing. tube and
the tube-spring, amounting as it does to the thickness of the intermediate ring,
allowing free room for the opening of the tube-spring when the metal stem of the
wine glass is pushed into it. In this arrangement I make the upper part of the
casing tube to form a neck part between the bottom of the cup or socket attached
to the wine glass and the handle proper into which the lower part of the casing
tube is fixed. The length of the casing tube which projects from the handle is

page_text: regulated so as to allow sufficient length of neck in addition to that of the cap or
socket that together there may be enough length of neck to permit of the wine
glass being removed and replaced in its seat in the stand or holder by the user with
the facility desired. With this object also I make the diameters of the cylindrical
part of the cup or socket of the wine glass and of the casing tube attached to the
handle to coincide and leave at their junction an even surface without step or
irregularity which might catch against the sides of the opening through which the
neck has to pass when the wine glass is removed from or replaced on its seat in the
stand or holder. I prefer to make the casing tube to project from the handle
sufficiently to allow also of the placing of a small half rounded ring upon it just
above the handle proper. This ring may serve as a stop to give the distance which
the casing tube should project from the handle to afford the desired length of neck
as before explained. It will also cover the joining of the casing tube with the
handle and give finish to the work.
A casing Lube such as have described above may be employed when the split-
tube-spring is replaced by a socket with a screw thread within it to receive a stem
with a corresponding screw fixed upon the wine glass or where the fastening
together of the parts is effected by other means.
Figures 10 and 11 illustrate in vertical section and in plan the arrangement of
the split-tube spring for attaching the handle to the metal stem de is the split
tube spring the intermediate ring- the casing or covering tube and the half
rounded distance ring fastened to the covering tube g, the upper part of which g¹
forms the neck while the lower part g2 passes into the handle B.
Figure 12 represents the metal stem d with the cup or socket e upon it held in
its place by the split tube spring by the action of the ends of the spring tongues
upon the coned part of the stem dati and so by their action on that part of the
stem hold it firmly as above explained.
Figure 13 which is drawn to the smaller scale indicates the wine glass A with its
circular projection or button a and cup or socket c with handle B attached by the
means already fully indicated and described.
In order that the handles of the wine glasses may be held by the user with
greater ease and convenience and not be liable to shift or slip downwards in the
hand but that although lightly and freely held or with little effort and attention
the wine glass may nevertheless retain its position with respect to its distance from
the hand so as to leave free room or clear length of neck for placing the wine glass
on its seat in the stand or holder, in order also that when the wine glass is to be
removed from the stand or holder the user may be caused more readily to take
hold of the handle at a convenient distance from the seat of the wine glass so as to
permit of the raising of the wine glass clear of its seat and the withdrawing it from
the stand or holder without the hand coming into contact with the ends of the seat
opening in the stand or holder, I form the handles of the wine glasses with pro-
jecting part or parts or of parts of varying diameters and forms arranged suitably to
effect the objects above explained.
The handle B in Figure 13 it will be observed is formed with a projecting part
at which serves to prevent its slipping down in the hand lower than convenient
when used. Other forms of handles may be used with projections to serve the
same purpose.
I have stated with reference to the projections or buttons formed on my
improved wine glasses for the purpose of centering and steadying them when placed
in the stand or holder as well as with reference to the part surrounding the button
or projection upon which part the wine glass rests when placed on its seat in its
stand or holder and the short glass stem projecting from the bottom of the wine
glass that they should be accurately formed and central with the wine glass and
seeing that in the ordinary manufacture this result is difficult of attainment to the
point of accuracy desirable I provide special apparatus for grinding the projection
or button on the bottom of the wine glass, the part of the bottom of the wine
glass round it where it rests on its seat in the stand or holder as well as the

page_text: short stem when such is used to which the cup or socket is fitted and cemented
also in the case when the button is formed in metal or other material and
cemented to the bottom of the wine glass to grind the wine glass to receive
it and when the projection or button is formed in one piece with the cup or
socket to grind the glass round the short stem, when such stem is provided,
as well as the short stem itself, ready to receive the cup or socket and the
projection or button combined. In this apparatus ] use the ordinary grinding and
finishing wheels of suitable form fixed on running spindles. The wine glass is
centered and held in a centering case consisting of a circular base plate with boss
rising in the centre terminating at the top in a female or male centre, this boss is
bored up nearly its full height with a cylindrical hole so that when placed upon a
pin fitting the hole it will turn truly. Over the outside of this boss reaching down
nearly to the base plate is a tubular piece closed at the top end where in the centre
is placed a pointed screw to rest in the female centre in the boss below. On the
point of this screw the tubular piece is supported and turns and moves freely. At
the bottom of the tubular piece near the base plate is fixed a circular platform on
which is placed a flat ring of india rubber leather or other suitable material for the
edge of the wine glass to rest upon while another ring of india rubber leather or
other suitable material of the internal diameter of the mouth of the wine glass and
with a hole fitting the tubular piece is put on to it and brought down to rest upon
the ring already placed on the platform being also of smaller diameter than the
ring on which it rests.
Thus while the wine glass rests on its edge on the lower flat ring it is centered
by the circumference of the upper ring which passes into it. There is a ring of
metal fixed to the base plate, it rises up around the platform leaving a sufficient
clear space bet.reen. This ring is screwed to fit a cap or covering case which
encircles the wine glass and which is provided with an internal ledge at the top
which comes against a metal ring with leather or other suitable lining and formed
to suit the outer rounded portion of the bottom of the glass when the casing is
screwed down to fix the wine glass. Thus the wine glass is held central. The
grinding apparatus is provided with a lever or its equivalent adjustable by screws
and stops which is free to be vibrated on its axis; at the end of this lever is a pin
which fits the hole in the central boss of the centering case which can be turned
round when placed upon the pin of the lever. The adjustments applied to the lever
having been arranged to suit the position of the wine glass in respect to the grinding
wheel the glass is brough against the wheel with the greatest faility and accuracy
and as, with the centering case, it can be turned round on the pin on the end of the
lever while the operation of grinding is being performed it can be ground truly, a
stop against which the lever arrives being adjusted for the diameter of the parts.
By means of the apparatus above described I am enabled not only to secure accuracy
in the formation of the parts referred to but great economy in the execution of the work.
Figure 14 represents a section of the centering case, together with the upper part
of the lever upon which it is carried; the glass is also shown in its place within the
case. Figure 15 shows a side elevation and Figure 16 is an end clevation of the
case and the glass within it is partly seen. Figure 17 is also an end elevation of
the centering case, it is here shown empty, the lever which carries the case is seen
and also the stop which limits the movement of the lever. Figure 18 shows a

In order to adapt the centering case for a glass of another size or form it is
necessary to change the parts m* and
When the apparatus is in use the centering case advanced by hand towards the
cutting wheel and as the work progresses the case is slowly turned in the direction
indicated by an arrow in Figure 17. A spring tends to draw back the lever r to
remove the work from the cutting wheel.
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
1. A footless wine glass adapted to receive a handle and to be supported in a
stand or holder, such glass having a circular projection or button rounded on the
edge around the stem at the bottom of the glass conforming to the circular
opening in the stand or holder around the seat therein in which the glass is
carried.
2. A footless wine glass with a cylindrical stem at the bottom cemented into a
cylindrical metal cup to which is secured the metal stem which serves to connect
the glass with its handle.
3. A footless wine glass fixed by its stem to a cylindrical metal cup; such cup
being raised from a sheet metal blank, perforated at the bottom and secured to a
metal stem by forcing the same into the cup and through the hole therein until the
head which is formed on the stem to accurately fit the cup, rests upon the bottom
thereof and is tightly embraced by the sides.
4. A. handle to receive a footless wine glass; such handle being provided with a
split tube spring to which it is attached by an intermediate ring and a casing or
covering tube which latter is directly fixed to the handle.
5. A footless wine glass, and a handle, the said parts being held together by a
split tube spring in the handle and a metal stem attached to the glass, such stem
having a cone surface upon it which is pressed upon on opposite sides by the split
tube spring so that the tendency of the spring when the glass is in place is to draw
the stem further into the split tube.
6. A. footless wine glass and handle substantially as described and shown in
Figure 13.
7. Apparatus to be used in grinding footless wine glasses, consisting of a centering
case mounted on a pin or axis on which it can revolve, and provided with a pivoted
platform and a cap so arranged that the glass being within the case and the cap
being applied the glass becomes nipped between india rubber or like surfaces upon
the cap and platform respectively and firmly held centrally within the case with
the base and stem exposed conveniently for the grinding operation to be
performed.
8. Apparatus to be used in grinding footless wine glasses and consisting of a
centering case in which the glass is firmly held with the base and stem exposed
conveniently for the cutting operation, a pin on which the centering case can turn
truly, a lever carrying the pin and limited in its movement by an adjustable stop
and a cutting wheel; the whole so arranged that the glass can be brought against
the cutting wheel and exposed equally to its action all around its stein whereby
the said stem and the base of the glass around the stem are reduced to a
true form.
