Year: 1877

page_text: LETTERS PATENT to Henry Charles Taylor, of the Firm of Robert Walter
Winfield and Company, of Birmingham, in the County of Warwick, Merchants
and Manufacturers, for the Invention of "IMPROVEMENTS IN ORNAMENTING
METALS, AND IN TOOLS TO BE USED FOR THAT PURPOSE."
Sealed the 15th September 1877, and dated the 5th April 1877.
PROVISIONAL SPECIFICATION left by the said Henry Charles Taylor at the
Office of the Commissioners of Patents on the 5th April 1877.

of Birmingham, in the County of Warwick, Merchants and Manufacturers.
"IMPROVEMENTS IN ORNAMENTING METALS, AND IN TOOLS TO BE USED FOR THAT
PURPOSE."
My said Invention is applicable principally to the ornamenting of tubes and
tubular articles and rods of metal, but may also be applied to the ornamenting of
metallic articles of other figures.
My Invention is especially applicable to the production of milled, striated, matted,
or dead, or rough surfaces.
I will describe my Invention as applied to the ornamenting of a cylindrical
brass tube.
I take two tools having engraved or otherwise produced upon them a pattern the
counterpart of that to be produced upon the tube. When a matted surface is to be
produced, two ordinary flat files or rasps will answer the purpose. One of these
tools is laid upon a fixed support, the tube to be ornamented is placed upon it,
crossing it, and the other file or rasp is applied to the upper surface of the tube.
A forward and backward motion is given to the upper file, considerable pressure
being applied, and the tube is thus rolled backwards and forwards under pressure
between the toothed surfaces of the two files. The result is the impressing of a
matted or toothed surface upon the tube. After one portion of the tube has been
operated upon, other portions may be similarly treated, and the whole or any
required portion or portions of the tube may be operated upon. Portions of the
matted surface may afterwards be removed by burnishing, turning, or otherwise,
according to the pattern required.

page_text: Instead of files, specially prepared steel or other tools having surfaces of any
required width inay be employed, and any desired tooth, grain, or pattern may be
made on the tools.
Instead of employing two tools as described, having matted or other like surfaces,
one only of the tools (either the stationary or moveable one) may have a matted or
other like surface, the other tool being plain.
Conical tubes or fluted tubes, or tubes with bulbous portions may be ornamented
according to my Invention. In ornamenting bulbous tubular articles, either flat
files or file-like tools may be employed and made to operate upon the curved surface
by the manipulation of the workman; or tools of a concave figure may be employed,
and for the hollow surfaces convex tools may be employed.
My improvements in tools for ornamenting metals consist in making the flat,
concave or convex tools, having matted, striated, or other like surfaces herein-before
referred to.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Henry Charles Taylor in the Great Seal Patent Office on the 28th
September 1877.

"IMPROVEMENTS IN ORNAMENTING METALS, AND IN TOOLS TO BE USED FOR THAT
PURPOSE."
My said Invention is applicable principally to the ornamenting of tubes and
tubular articles and rods of metal, but may also be applied to the ornamenting of
metallic articles of other figures.
My Invention is especially applicable to the production of milled, striated, matted,
or dead, or rough surfaces.
I will describe my Invention as applied to the ornamenting of a cylindrical brass
tube.
I take two tools having engraved or otherwise produced upon them a pattern,
the counter part of that to be produced upon the tube. When a matted surface. is
to be produced, two ordinary flat files or rasps will answer the purpose. One of
these tools is laid upon a fixed support, the tube to be ornamented is placed upon it,
crossing it, and the other file or rasp in a position parallel to the lower one is
applied to the upper surface of the tube. The tube may be supported by means of
an internal mandril.
A forward and backward motion is given to the upper file, considerable pressure
being applied, and the tube is thus rolled backwards and forwards under pressure,
between the toothed surfaces of the two files. The result is the impressing of a
matted or toothed surface upon the tube. After one portion of the tube has been
operated upon, other portions may be similarly treated, and the whole, or any
required portion or portions of the tube may be opperated upon. Portions of the
matted surface may afterwards be removed by burnishing, turning, or otherwise,
according to the pattern required.
Instead of files, specially prepared steel or other tools having surfaces of any
required width may be employed, and any desired tooth, grain, or pattern may be
made on the tools.
Instead of employing two tools as described, having matted or other like surfaces,
one only of the tools (either the stationary or moveable one) may have a matted or
other like surface, the other tool being plain.
Conical tubes or fluted tubes, or tubes with bulbous portions may be ornamented
according to my Invention. In ornamenting bulbous tubular articles, either flat
files or file -like tools may be employed and made to operate upon the curved surface

page_text: by the manipulation of the workman, or tools of a concave figuro may be employed,
and for hollow surfaces convex tools may be employed.
My improvements in tools for ornamenting metals consist in making the flat,
concave, or convex tools having matted, striated, or other like surfaces herein-before
referred to.
The ornamenting process herein-before described may be effected by hand, but
the said ornamenting process may also be effected by the use of the apparatus and
tools, which I will now proceed to describe; it must however be understood that I
do not limit myself thereto, as other analogous apparatus will answer the same
purpose.
Figure 1 represents in plan, Figure 2 in side elevation, and Figure 3 in end
elevation a machine and tools for producing a matted, striated, or rough surface
upon a tubular article according to my Invention. In the said machine a fixed file
or impressing tool and a moveable file or impressing tool are employed.
The same letters of reference indicato the same parts in Figures 1, 2, and 3. a is
the moveable file or tool carried by the reciprocating dovetail slide 6 working on the
bed of the machine, and c is the upper fixed file or tool carried in the pressure plate
or block d, which plate or block is capable of slightly yielding. The said block or
plate d is pressed down by the coiled springs c, e, the said coiled springs bearing at
one end against the said block or plate, and at the other end against the abutments
at ff, the said abutments being adjusted and fixed by screw nuts as represented.
By means of the plate or block d, the required pressure is put upon the tube during
the ornamenting process. The acting surfaces of the two files or tools a, c, have any
desired tooth, grain, or pattern made upon them, according to the character of the
surface to be produced. The reciprocating motion of the slide b, carrying the bottom
file or tool a, is effected by the connecting rod g, jointed to a crank pin at h on the
crank plate i, the said crank plate being fixed on the driving shaft k of the machine.
This shaft is furnished with a fly wheel and fast and loose pulleys, as represented.
The tube to be ornamented is placed between the two files or tools a, c, as illus-
trated, the said tube being supported in any convenient way at its ends so that it
is capable of a rolling motion or motion upon its axis, and the parallelism of the tube
preserved during its rolling motion. This supporting and guiding of the tube may
be conveniently effected by hand. The tube may however be supported and guided
by mechanical means. By the motion of the slide b, the tube is rolled backwards
and forwards under pressure between the toothed surfaces of the files or tools a, c,
whereby a matted or toothed or other impressed surface is produced on the tube.
After that part of the tube in contact with the two files or tools a, c, has been im-
pressed the upper file or tool c is lifted by the lifting of the pressure plate d, and
the tube is moved in the direction of the arrow, Figure 1, so as to bring a plain part
of the tube under the files or tools, when a second portion may be ornamented, and
so on. The lifting of the upper file or tool c from the lower file or tool a may be
effected automatically by means of a cam on the driving shaft k, acting through
connecting rods and levers upon the sliding pressing plate or block d. When the
parts of the tube or article to be ornamented are concave, the acting parts of the
said tools or files a, c, are made convex, and when the parts of tube or article
to be ornamented are convex, the acting parts of the tools or files a, c, are made
concave.
Although I have only shown a fixed file or tool, and a moveable file or tool, yet
both files or tools may be made moveable.
Instead of employing reciprocating files or tools as described and represented, cir-
cular, impressing, or roll-like tools may be employed as illustrated in side elevation
in Figure 4, and end elevation in Figure 5, where m, n, are the two circular roll-like
tools, between which the surface of the tube is roughed, matted, or otherwise im-
pressed. The upper circular tool m turns in bearings in the frame of the machine
and is rotated by the frictional contact of the tube being ornamented. By thus
moving the upper tool m, the required drag or retardation is put upon it necessary
for the ornamenting process. The required pressure is put upon the said upper tool

page_text: m by a strong spring acting upon the bearings of the rolls. The lower circular
tool n is driven from the driving shaft 2 by the spur gearing at q, q. The tube is
maintained in its position between the tools by the supporting roller r, situated
between the two tools. Any required speed may be given to the lower tool n by
adopting different gearing at q. "For the purpose of lifting the upper circular tool m
from the lower tool n for releasing the tube and permitting the said tube to be
moved for ornamenting a fresh portion, I employ the following automatic arrange-
ment of parts. On the driving shaft p is a pinion S, which gears with a spur wheel t
on a parallel shaft u. On the shaft u is a cam v, the rise of which cam acts upon
the tooth or pallet won the lever x. This lever is connected by rods y to the
levers z, z, in which the ends of the axis of the upper tool m turn. By this
arrangement the upper tool m is lifted from the lower tool n after the latter tool
has made several rotations, and the tube between the said tools, thereby released
ready to be moved forward for bringing a fresh portion of it between the said
tools.

Figure 6 illustrates the application of my Invention to the ornamenting of concave
and convex tubular surfaces. In order to operate upon the concavity a, the acting
surface of the tool b (the said tool being shown in section) must have a concavity
similar to the concavity a. In order to operate upon the convex or bulbous part c
of the tube, the surface of the tool d (the said tool being shown in section) must have
a concavity corresponding to the convexity of the part c.
The tools band d may
either be straight and have a reciprocating motion, or they may be roll-like and
rotate upon axes.
My Invention may be applied to the ornamenting of flat metallic surfaces as well
as to the ornamenting of tubular surfaces. In ornamenting flat surfaces, the im-
pressing tool having the figure of a circular file, is made to roll under pressure upon
the flat surface to be ornamented, thus in Figures 1, 2, and 3, the tube / would
represent the impressing or rolling file or tool, and a the flat surface to be orna-
mented, the rolling tool 7 being pressed upon the surface a by the pressing plate d.
Having now described the nature of my Invention and the manner in which the
same is to be performed, I wish it to be understood that I claim as my Invention,-
The improvements in ornamenting metals, and in tools to be used for that purpose
herein-before described and illustrated in the accompanying Drawing; that is to
say impressing a matted, striated, rough grained, or other like surface upon tubular
and flat metallic articles by means of flat files or tools, or roll-like tools, having
properly prepared acting surfaces, the said files or tools being used and operating
substantially as described and illustrated.
Also the flat concave or convex tools herein-before described and illustrated,
having matted, striated, or other like surfaces engraved or otherwise produced upon
thom to be used in the said ornamenting process.
In witness whereof, I, the said Henry Charles Taylor, have hereunto set my
hand and seal, this Twenty-fourth day of September, in the year of our Lord
One thousand eight hundred and seventy-seven.
