of Middlesex, Engineer and Patent Agent, for the Invention of "IM-
PROVEMENTS IN ROSE ENGINES."-A communication from abroad by Anton
Schwitter and Lewis Schwitter, both of New York City, United States
of America.
Sealed the 22nd June 1866, and dated the 3rd March 1866.
PROVISIONAL SPECIFICATION left by the said William Clark at the
Office of the Commissioners of Patents, with his Petition, on the 3rd
March 1866.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said Invention.
for "IMPROVEMENTS IN ROSE ENGINES," to be as follows:-
Rose engines of the ordinary construction serve to produce curved or other
ornamental lines on the surfaces of pitchers, goblets, cups, or other articles
made of sheet metal, and the tools generally used for this purpose are sharp
pointed pieces of steel held firmly in a movable or adjustable rest. Such tools

page_text: are sufficient for the purpose for which they are intended, but they cannot be
used to ornament the surfaces of articles made of glass or other material of
such a nature that it cannot be cut by steel.
This Invention consists in the employment or use on a rose engine of a
rotating tool made of a composition of emery with liquid silex or of any other
suitable material, and applied in combination with a spindle and mechanism
of an ordinary rose engine in such a manner that by the action of said tool
lines or various designs can be produced on glass or on the surface of articles
made of glass or other similar material with the same facility as on articles
made of metal. The Invention consists also in the arrangement and use of a
binged tool holder in a rose, engine in combination with the revolving tool, and
with a carriage or slide moving backwards and forwards in a suitable rest in such
a manner that, by means of said rest, the tool can be adjusted to any desired
position in the usual manner, and by the hinged holder it can be brought up
to or removed from the surface of the work with the greatest ease and facility
and without danger of spoiling the work. The Invention consists, finally, in
the arrangement of a hinged or sliding supporting plate to which motion is
imparted by the action of an additional rosette in combination with the hinged
tool: holder of a rose engine in such a manner that motion can be imparted
to the tool in a direction parallel with the spindle, and corrugated- festoons
or other designs can be produced which cannot be produced-by-ordinary-rose
engines..
The Invention is illustrated in the accompanying Drawing, in which
Fig. 1 represents a plan or top view of the apparatus; Fig. 2 is a side elevation.
of the same; Fig. 3 is a transverse section of the same; Fig. 4 is a detached
plan or top view of a modified form of the supporting plate for the tool
holder. Similar letters of reference indicate corresponding parts.
A represents the table or platform which supports, the mechanism of an
ordinary rose engine, the spindle C of, which is, hung, in standards. B,, and
arranged in such a manner that a longitudinal sliding motion,, and also a
transverse motion, can be imparted to it by the action of the guide D, on the
rose E.in the usual manner;.or.if the rose engine is to be used for ornamenting
nothing. but articles of glass or other. fragile material; the, motion of the
spindle C may be confined simply to a longitudinal: sliding motion. E is the
tool which consists of a sharp. edged: disc. of copper or of emery: cemented
together. by liquid silex. or of any. other, suitable.material capable of cutting
glass or other vitreous material: The disc is mounted ion.a. spindle.a.which
has its bearings in two centre points .b secured in a fork c, which. is, adjustable

in a socket d on the top plate e of the tool holder. This top plate e also
supports a cage f, which forms the bearings for an axle g on which are
mounted two pulleys he, as shown in Fig. 1 of the Drawing. Another pulley
i is mounted on the spindle of the tool or disc F, and a rope j. which
round the latter pulley and through under the pulley h and then up to &
suitable driving shaft, serves to impart motion to the tool in the most
convenient manner. This belt or rope j, however, may be applied in any other
convenient manner. The top plate e connects by parallel rods k with the
bottom plate of the tool holder,. and said parallel rods are hinged so that
the tool can be moved towards or from the work with ease and convenience.
It must be remarked, however, that the connection between the top and
bottom plates of the tool holder can be effected by other means equivalent to
the parallel rods shown in the Drawings. The bottom plate I of the tool
holder is made either square,, as shown in Figs. 1,. 2, and 3, or it may be
made round, as shown in Fig. 4. In both cases it is secured to a bed plate
m which is hinged to the table A, so that it swings in a direction parallel to
the spindle of the rose engine. The bolt n which forms the connection
between the bottom plate and. bed plate m is made adjustable in a slot 0.
in said bed plate, and if the bottom plate is round it may be so arranged that
the same together with the tool holder can be turned in either direction.
An oscillating motion is imparted to the bed plate m by the action of a rose p,
which is mounted on the spindle C of the rose engine. This rose acts on an
arm q which extends from a vertical rock shaft r, and another arm s extending
from this rock shaft at right angles to the arm q connects by a rod t with the
bed plate, as shown in Figs. 1 and 2 of the Drawing. The shape of the rose
p is such that the oscillations of the bed plate m are slow as compared with
the reciprocating motions of the spindle C, and by this combined motion of
the spindle and bed plate designs can be produced, such for instance, as shown
in Fig. 1 of the Drawing, which cannot be produced by the ordinary rose
engine, or by a rose engine in which the bed plate m or its equivalent remains
stationary..
By the aid of this rose engine the operation of ornamenting articles of glass.
is rendered comparatively easy, and a great many designs can be produced
on such articles which cannot be imitated by hand.

by the said William Clark in the Great Seal Patent Office on the 30th
August 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLARK, of 53, Chancery Lane, in the County of Middlesex, Engineer and
Patent Agent, send greeting.
:
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of March, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Clark, Her special licence that I, the said William Clark,.
my executors, administrators, and assigns, or such others as I, the said William
Clark, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN ROSE ENGINES,"
a communication to me from abroad by Anton Schwitter and Lewis.
Schwitter, both of New York, United States of America, upon the condition
(amongst others) that I, the said William Clark, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar months.
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Clark, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say):
―
Rose engines of the ordinary construction serve to produce curved or other
ornamental lines on the surfaces of pitchers, goblets, cups, or other articles
made of sheet metal, and the tools generally used for this purpose are sharp
pointed pieces of steel held firmly in a movable or adjustable rest. Such tools
are sufficient for the purpose for which they are intended, but they cannot be
used to ornament the surface of articles made of glass or other material of
such a nature that it cannot be cut by steel.

page_text: This Invention consists in the employment or use on a rose engine of: a
rotating tool made of composition of emery with liquid silex or of any other
suitable material, and applied in combination with the spindle and mechanism
of an ordinary rose engine in such a manner that by the action of said tool
lines or various designs can be produced on glass or on the surface of articles
made of glass or other similar material with the same facility as on articles
made of metal. The Invention consists also in the arrangement and use of a
hinged tool holder in a rose engine in combination with the revolving tool,
and with a carriage or slide moving back and forth in a suitable rest, in such
a manner that, by means of said rest, the tool can be adjusted to any desired
position in the usual manner, and by the hinged holder, it can be brought up
to or removed from the surface of the work with the greatest ease and facility.
and without danger of spoiling the work. The Invention consists, finally, in
the arrangement of a hinged or sliding supporting plate to which motion. is
imparted by the action of an additional rosette in combination with the hinged.
tool holder of a rose engine in such a manner that motion can be imparted
to the tool in a direction parallel with the spindle, and corrugated festoons
or other designs can be produced which cannot be produced by ordinary rose
engines..
This Invention is illustrated in the acccompanying Drawing in which
Figure 1 represents a plan or top view of the same; Figure 2 is a
side elevation of the same; Figure 3 is a transverse section of the same;
Figure 4 is a detached plan or top view of a modified form of the supporting
plate for the tool holder. Similar letters of reference indicate corresponding
parts.
A represents the table or platform which supports the mechanism of an
ordinary rose engine, the spindle C of which is hung in standards B, and
arranged in such a manner that a longitudinal sliding motion, and also a
transverse motion can be imparted to it by the action of the guide. D on the
rose E in the usual manner; or, if the rose engine is to be used for ornamenting
nothing but articles of glass or other fragile material, the motion of the
spindle C may be confined simply to a longitudinal sliding motion. F is the
tool which consists of a sharp edged disk of copper or of emery cemented
together by liquid silex or of any other suitable material capable of cutting
glass or other vitreous material. This disc is mounted on a spindle a which
bas its bearings in two centre points 6 secured in a fork c, which is adjustable
in a socket d on the top plate e of the tool holder. This top plate e also
supports a cage f which forms the bearings for an axle g on which are

page_text: mounted two pulleys h, as shown in Figure 1 of the Drawing. Another
pulley is mounted on the spindle of the tool or disc F, and a rope j, which
passes round this latter pulley, and through under the pulleys and then up
to a suitable driving shaft, serves to impart motion to the tool in the most
convenient manner. This belt or rope j, however, may be applied in any other
convenient manner. The top plate e connects by parallel rods k with the
bottom plate of the tool holder, and said parallel rods are hinged so that the
tool can be moved towards and from the work with ease and convenience..
It must be remarked, however, that the connection between the top and bottom
plates of the tool holder can be effected by other means equivalent to the
parallel rods shown in the Drawings. The bottom plate of the tool holder
is made either square, as shown in Figures 1, 2, and 3, or it may be made
round, as shown in Figure 4. In both cases it is secured to a bed plate m
which is hinged to the table A so that it swings in a direction parallel to the
spindle of the rose engine. The bolt n which forms the connection between
the bottom plate l and bed plate m is made adjustable in a slot o in said bed
plate, and if the bottom plate is round it may be so arranged that the same
together with the tool holder can be turned in either direction. An oscillating
motion is imparted to the bed plate m by the action of a rose p which is
mounted on the spindle C of the rose engine. This rose acts on an arm q
which extends from a vertical rock shaft r, and another arm s extending from
this rock shaft at right angles to the arm a connects by a rod t with the bed
plate, as shown in Figures 1 and 2 of the Drawing. The shape of the rose p
is such that the oscillations of the bed plate m are slow as compared with the
reciprocating motions of the spindle C, and by this combined motion of the
spindle and bed plate designs can be produced, such for instance as shown
in Figure 1 of the Drawing which cannot be produced by the ordinary rose
engine or by a rose engine in which the bed plate m or its equivalent remains
stationary.
.
By the aid of this rose engine the operation of ornamenting articles of glass
is rendered comparatively easy, and a great many designs can be produced on
such articles which cannot be imitated by hand.
Having described the nature of this Invention, and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
herein-before in part recited Letters Patent is,-
1st, the use of a rotating tool in combination with an ordinary rose engine
arranged and operating substantially as and for the purpose set forth.
2ndly, the hinged tool holder iu combination with a suitable bed plate, and

page_text: with the spindle of the rose engine constructed and operating substantially as
and for the purpose described.
3rdly, the hinged or movable bed plate m in combination with the tool
holder and spindle of a rose engine constructed and operating substantially
as and for the purpose set forth.
In witness whereof, I, the said William Clark, have hereunto set my hand
and seal, this Twenty-ninth day of August, in the year of our Lord One
thousand eight hundred and sixty-six.
Witness,
JAMES DAISH,
