Year: 1858

page_text: LETTERS PATENT to Hypolite Dauphin, of Nantes, in the Empire of
France, Jeweller, for the Invention of "A NEW OR IMPROVED MACHINE
"
Sealed the 14th August 1858, and dated the 10th March 1858.
PROVISIONAL SPECIFICATION left by the said Hypolite Dauphin at
the Office of the Commissioners of Patents, with his Petition, on the
10th March 1858.
I, HYPOLITE DAUPHIN, of Nantes, in the Empire of France, Jeweller,
do hereby declare the nature of my Invention of "A NEW OR IMPROVED
MACHINE FOR GIVING TO METALLIC BANDS A CIRCULAR OR PARTLY CIRCULAR FORM,"
to be as follows, that is to say:
The object of the machine is to give to metallic bands, first, a circular form
of any given diameter for the manufacture of hoops for casks, tuns, and other
vessels; secondly, a partly circular or curved shape, applicable wherever
curved metal bands are used. This machine consists of two rollers supported
between two standards fixed on a foundation plate, and held together at their
upper part by two cross beans. The lower roller is placed in a horizontal
position; the upper roller is moveable by means of wedges which are caused
to act on each of its extremities. The wedges are independent of each other,
and by pressing more on one end of the upper roller than on the other, (I give
to it an inclined position with respect to the lower roller. These wedges are

page_text: moved by adjusting screws placed at the top of the standard. At each
extremity of the upper roller is fixed an arm having a stud working in a
groove made in the wedges. These arms give motion to an indicator placed
above the machine, which shows the inclination of the roller. The pressure
of the wedges on the journal of the rollers is communicated by means of a
wedge block, which presses on the spherical surface of a guide block or bearing,
permitting the adjustment of the pressure. A metallic band is introduced in a
rectilinear direction between the two rollers. The inclination of one of the
rollers causes one edge of the band to be more compressed than the other, and
the band to receive a relative and uniform extension in its whole length. The
band will thus be turned to a perfect circle. Guides are placed to support the
band in its horizontal direction. Another guide is also employed at the egress,
to give to the band another curve, which causes it to assume a spiral form.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Hypolite Dauphin in the Great Seal Patent Office on the
7th September 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HYPOLITE
DAUPHIN, of Nantes, in the Empire of France, Jeweller, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of March, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Hypolite Dauphin, Her special license that I, the
'said Hypolite Dauphin, my executors, administrators, and assigns, or such
others as I, the said Hypolite Dauphin, 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 of "A NEW OR IMPROVED MACHINE FOR GIVING TO METALLIC
BANDS A CIRCULAR OR PARTLY CIRCULAR FORM," upon the condition (amongst
others) that I, the said Hypolite Dauphin, my executors or administrators,
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 Inven-
tion, and in what manner the same was to be performed, and cause the same
.

page_text: 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 Hypolite Dauphin, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention consists in constructing a machine with two rollers or
cylinders, the upper roller being placed at an angle to the other by means of
wedges and set screws, and in the use of guides for giving to bands of iron or
other metal a circular and circular conical form, thus superseding the process
of hammering. for the manufacture of hoops for casks, barrels, tuns, and other
similar vessels. The machine may be also employed for giving to metallic
bands a curved shape applicable to the construction of arches, vaults, and for
other purposes.
Having thus briefly stated the nature of the Invention, I will now proceed
to describe the mode of carrying the same into effect, reference being had to
the accompanying Sheet of Drawings, in which Figure 1 represents a side
view, and Figure 2 an end view, both in partial section, of the new or improved
machine. This machine is composed of two cast-iron rollers or cylinders A, B,
supported between two cast-iron standards C, C, which are fixed by nuts and
bolts D, D, to a foundation plate. E, and held together at their upper part by
two tie plates F, F¹. The lower roller is placed in a horizontal position, and
the upper roller is adjustable by means of wedges G, G, which are caused to
act on each of its journals. These wedges are independent of each other, and
by pressing more on one journal than on the other, I give to the upper
roller A. an inclination to the lower roller B. The horizontal set screws
H, H, serve to adjust the pressure and inclination of the roller A, and are put
in motion by turning the winch handle I, which actuates the pinion J, gearing
with the spur wheels K, K', keyed to the set screws H, H'. At each
extremity of the upper roller A is placed an arm L, having
working in an oblique. groove N, made in the wedges. G, G.
attached and give motion to an indicator O, which shows on the graduated
scale .P, fixed to the supporting rods; O', the angle or inclination of the
roller A. The pressure of the wedges G, G, on the journals Q, Q, and
brasses R,.R,. of the rollers is communicated by means of sliding or guide
blocks S, S, the upper part of each of which is spherical and fits into a moveable
wedge block T. This arrangement. permits the adjustment of the pressure on
the rollers. A metallic band T being introduced in a rectilinear direction
a stud or pin M,
These arms are

page_text: between the two rollers, the inclination of one. of the rollers causes one edge
of the band to be more compressed than the other, and the band to receive a
relative and uniform extension in its whole length; the band will thus be
turned to a perfect circle. Guides are placed to support the band in its hori-
zontal direction.
.
For making iron hoops for casks, the guides U, V, may be added, the descrip-
tion of which is as follows:-U. is a perpendicular guide, consisting of two
moveable rollers W (one of which only is shown), which may be placed at the
necessary distance apart, according to the width of the metallic band. V,
another guide, formed with a curved plate Y, in the middle of which is placed
a small roller X, the pressure of which may be regulated at will. The band of
iron or other metal, by passing through these guides, is caused to roll into a
circular and conical form of the necessary diameter. The upper cylinder A
receives a rotatory motion by means of the pinion Z, fitted on the axle Z³,
which pinion gears with another pinion a, fixed to the axis 6 of the roller B.
At the opposite end of the axis b is a large spur wheel c, gearing with a pinion
d on the axle e, working in the bearings or pedestals f; 9, pulley for driving
the rollers of the machine. This machine, which may be driven by steam
or other motive power, is also applicable for forming curved iron bands
to be used in the construction of vaults, arches, and for other purposes.
Having now described the nature of my Invention, and the mode of per-
forming the same, I would have it understood, in conclusion, that I do not
restrict myself to the exact details of construction, as the same may be varied
without departing from the principle of my Invention; what I claim as new
and desire to be protected by the herein-before in part recited Letters
Patent, is,-
First, the general arrangement and construction of the machine for giving
a circular, a circular and conical; or curved form, to bands of iron or other
metal for the manufacture of hoops for casks, barrels, and other like vessels,
and curved iron bands for arches, vaults, and other purposes, as herein-before
described and shown in the annexed Sheet of Drawings.
Secondly, the mode or method of giving the pressure and inclination to the
roller or cylinder A, by means of the wedges G, G, and set screws H, H¹, as
herein before described and-represented-in-the annexed-Sheet-of-Drawings.
Thirdly, the employment and arrangement of the guides U, V, in combina-
tion with the rollers or cylinders A, B, for the manufacture of circular and
circular conical hoops for casks and barrels, as herein-before described and
shewn in the accompanying Sheet of Drawings.

page_text: Fourthly, the construction and arrangement of the moveable arms L, L, in
combination with the indicator O and scale P, for showing the inclination of
the roller A, as herein-before described and referred to in the annexed Sheet
of Drawings.
In witness whereof, I, the said Hypolite Dauphin, have hereunto set
my hand and seal, this Twenty-seventh day of August, in the year of
our Lord One thousand eight hundred and fifty-eight.
