of Plates of Glass or other Substance.
JOHN ROWLAND PALMER Cabinet Maker 43 Victoria Grove Ashley Street Bristol
Street Birmingham do hereby declare the nature of this invention to be as
follows:-
I construct a table of any convenient size and shape.
To this table I fasten the glass.
This table is constructed so that the part to which the glass is fastened may be
readily removed and replaced by another part of different size or shape.
This table is made to roll or slide upon its frame or support, so that any part of the
edge or surface of the glass attached to it may be brought in contact with the revolving
cutters.
Over, or under, or at the side of this table I cause to revolve one or more cutters or
discs whose circumference or periphery is suitably formed to cut and polish the
required mould or pattern upon the glass or other substance, which said cutters may
be made of stone, iron, felt, or other material, and they may be used with or without
the usual cutting and polishing materials.
These cutters may be made to revolve horizontally, or vertically, or at any other
required angle.
.
The said revolving cuiters and table supporting the glass I make adjustable to each
other, in such manner that the revolving cutters and glass may he brought in contact
with each other at any required angle.
I also make the revolving cutters and table supporting the glass adjustable to each
other, in such manner, that on the revolving cutters and glass being brought in
contact the revolving cutters shall cut and polish a mould or pattern upon the edge or
surface of the glass in a circle or portion of a circle, an oval or portion of an oval, an
ellipse or portion of an ellipse, or other required figure.
I also make that portion of the table to which the glass is affixed capable of
movement in a circular or oval or elliptical or other required direction or manner.
I also make the revolving cutters and table to which the glass is affixed, adjustable
to each other in such manner, that the revolving cutters may be brought in contact
with any part of the edge or surface of the glass.

COMPLETE SPECIFICATION.
A Machine for Moulding and Ornamenting the Edges and Surfaces
of Plates of Glass or other Substance.
1, JOHN ROWLAND PALMER, of 43 Victoria Grove, Ashley Street, Birmingham, in
the county of Warwick Cabinet Maker, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to machinery primarily intended for moulding and orna-
menting the edges and surface of plates of glass, but which may also be used upon
other substances; and consists of the improvements hereinafter named.
I construct a suitable base to receive a sliding table or frame, upon which latter is
mounted the table proper to receive the glass. This table proper is made removable,
so that others varying in size and shape inay be substituted according to the work to

page_text: be done. Both a sliding to and fro motion, and also a turn about motion may be
imparted to this table.
Over, or under, or at the side of this table I cause to revolve one or more cutters or
discs, whose circumference or periphery is suitably formed to cut and polish the
required mould, shape, or pattern, upon the glass or other substance, which said
cutters may be made of stone, irou, felt or other material, and may be used with the
usual cutting and polishing materials.
The said cutters may be made to revolve either horizontally, or vertically, or at any
other required angle.
The said revolving cutters and table supporting the glass, I make adjustable to each
other, in such a manner, that the revolving cutters and glass may be brought in
contact at any required angle.
I also make the revolving cutters and the table supporting the glass adjustable to
each other, in such a manner, that upon the revolving cutters, and the glass, being
brought in contact, the revolving cutters shall cut and polish a mould or pattern upon
the edge or surface of the glass, in a circle or portion of a circle, an oval or portion of
an oval, an ellipse or portion of an ellipse, or other required figure.
I also make that part of the table to which the glass is affixed, capable of move-
ment in a circular, or oval, or elliptical, or other required direction or manner.
I also make the revolving cutters and table to which the glass is affixed, adjustable
to each other in such a manner that the revolving cutters may be brought in contact
with any portion of the edge or surface of the glass.
I will now more particularly describe how this my invention is to be performed,
with the aid of the accompanying illustrative sheets of drawings, upon which are
views and figures of reference, and in which :-Fig. 1, is a side elevation, Fig. 2 a
plan, Fig. 3 an end elevation of the principal parts of a machine according to my
invention. Figs. 4 to 11 inclusive, being detailed views of parts of this my
invention.
1, is a bed or base upon which the superstructure of the machine is built.
2, 2, are the two sides of a framework, which is completed by the two cross
connecting parts 3, 3. Vertical and angular adjustment is given to this frame by
means of the vertical screws 4, 4, and 5, 5, (only one of the screws 4, being shown)
6, 6, are worm wheel screw nuts (one only shown) taking on to the screws 4, 4, and
into which gears the worms 7, 7, (one only being shown) which is rotated by means
of the hand wheel 8. At the upper end of the screws 5, 5, and in one therewith, are
carried the worm wheels 9, 9, (one only is seen) into which gears the worms 10, 10,
which are rotated by either of the hand wheels 11, 11. The upper end of the
screws 5, 5, takes a bearing in the ends of the frame. By these means it will be
readily seen that the table at either end may be adjusted to varying angles within the
limit of the range of the screws. It will be noticed, that in order to give sufficient
rigidity to the frame 2, the screws 4, are not capable of (vertical) oscillation, while
the screws 5, are provided with a compensating joint at 12. The worm-wheels 9, 9,
worms 10, 10, hand-wheels 11, 11, together with the cross bar or frame 13, are
connected to the frame 2; but the screwnut wheels 6, 6, worms 7, 7, and hand-
wheel 8, are secured to the frame or base 1.
Upon the frame 2, (see Figs. 2, 3, 4, & 5,) is carried the sliding support or
frame 14, which is capable of a longitudinal movement, but which may be also secured
at any desired point by the screw pin 15, or other suitable device. At 16, a central
hole or bearing is provided in the frame 14 to receive a removable piece 17, which is
capable of an easy rotating movement, with its pin in the hole 16. To this piece 17,
is securely attached a plate 18 (see Figs. 1 & 3) which is made of any such shape
or size that may be required to suit the piece of glass which is to be operated
upon.
Connected rigidly to the sliding frame 14, in any convenient manner, is the pillar 19,
(Fig. 1) upon which is carried the arm 20. At the end of this arm is carried the
pressure foot 21, having claws 22, (generally three). Between these claws and the

page_text: plate 18, is placed the glass to be operated upon. The pressure of this foot 21, is
modified by means of the enclosed spring 23, (as seen in detail view) so that an undue
pressure upon the glass may be thereby avoided.
24, is the mill which may be varied in size and shape of periphery as may be con-
venient for the work in hand. This mill is carried in suitable bearings 25, 25, and
driven by band, or cord, or in other suitable manner. Generally the driving band or
cord would assume a horizontal line of driving, the pulleys 26, being suitably shaped
therefor. As seen in Fig. 1, this mill 24, carried in bearings which are fixed to
the bed 1.
In some cases however, I may provide that this mill spindle 27, shall be capable of
angular adjustment. In Figs. 6, 7, and 8, I illustrate how this may be done, although
this admits of variation in the manner of carrying it out:-
Upon the frame 28, is provided a trunnion bearing 29, upon and about which
swings the quadrantal bracket 30, having upon its outer edge, gear teeth 31, engaging
with the worm 32, which lattor is operated by the wheel 33. Fig. 8, clearly shows
how the mill 24, may be adjusted to any angle within the range of the circular rack
teeth 31. In some instances, this adjustable arrangement may be substituted in the
place of that illustrated in Fig. 1, in combination with the adjustable table as there
shown, while in other cases, it may be used in combination with the frame 2, and
its superstructure, without the angular adjustment to the said frame 2.
Further, in some instances I may carry the frame 28, and its accompanying parts,
in an inverted position over and above the table, as in this manner, there would be
an increase of table room, in which case the upper surface of the glass would be
operated upon.
In cutting or shaping lines or figures upon the surface of glass, it is very important
that the periphery of the mill shall assume a greater or less acute angle. By these
my improvements it will be readily seen that I can easily accomplish this in circular
or irregular lines upon the glass.
In some instances, it is desirable to operate upon the edge of a circular hole. To
effect this, I modify the form of the sliding frame 14 (Fig. 2) and make it as seen
at 34, Figs. 4 and 5. Its central part is made circular to receive a circular movement
plate 35. The upper table 36 is then secured upon the piece 35, and provided with a
hole 37, of the required size. Upon this table 36. is placed the plate of glass, with
the Lo'e or opening to be operated upon, above the central opening in the piece 35.
Hence the mill may be made to operate thereon, from above or below.
In adapting this my improved machine for the production of elliptical forms I
proceed somewhat thus:-
In the hole 16, (Fig. 2) I place a piece 17, but having a square part formed upon
the lower part of its pin. Upon this piece 17 is secured the upper table of the
required shape, upon which latter is placed the glass, each as before described. I
now further provide an under longitudinal slide 38, (see Figs. 9, 10, & 11). Upon
this slide 38, is a cross slide 39, having thereon a swivel block 40, which carries the
controlling bar 41, at the outer end of which is the square hole 42. Now, by
adjusting the bar 41, to the required distance from the swivel block, and securing
the slide 38, in its position, by means of the pins 43, 43, firmly to the frame 2, 2;
then passing the pin of the piece 17, first through the hole 16, and then on through
the hole 42, the square part upon the pin taking into the square hole, a compound
motion is obtained, that is, in turning the table around, the slide 38 being a
fixture--the slide 39, and swivel block 40, have a given amount of cross motion, by
reason of the circular motion imparted to the bar 41. This necessarily draws the
slide 4, and with it the glass being operated upon, nearer to, or farther from the
nil as it is turned about its centre 16, thus giving the required elliptical form
thereto. The adjustment of the bar 41, permitting of any required variation in the
two diameters of the ellipse, within its range.
Further. In order to produce work of an irregular shape, I may proceed somewhat
as follows:-
Upon the lower end of the pin at 16, (see Fig. 2) I provide the former 44, which

page_text: is made to any required form or size. To the frame 2, 2, is firmly connecte.l the
cross piece 45, having upon it the roller 46, which said roller, impinges upon the
former 44, as shown. The slide 14, together with its superstructure is, as before,
free to slide longitudinally and is kept up to the roller 46, by means of springs 47, or
other suitable device. It will be readily seen that as the upper table and glass, is
turned around, a line or surface, upon the glass, is presented to the mill, similar and
according to the former 44.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is :-
