A NEW OR IMPROVED STRAP OR BAND FOR WORKING STAMPS, RAISING WEIGHTS, AND TRANSMITTING POWER GENERALLY
Year: 1856

page_text: LETTERS PATENT to Charles Vaughan, of Birmingham, in the County.
of Warwick, and William James Vaughan, of Birmingham aforesaid,
and Richard Vaughan, of Birmingham aforesaid, Manufacturers and
Copartners, for the Invention of "A NEW OR IMPROVED STRAP OR BAND FOR
WORKING STAMPS, RAISING WEIGHTS, AND TRANSMITTING POWER GENERALLY."
Sealed the 5th May 1857, and dated the 8th November 1856.
PROVISIONAL SPECIFICATION left by the said Charles Vaughan, William
James Vaughan, and Richard Vaughan at the Office of the Commissioners
of Patents, with their Petition, on the 8th November 1856.
We, CHARLES VAUGHAN, of Birmingham, in the County of Warwick, and
WILLIAM JAMES VAUGHAN, of Birmingham aforesaid, and Richard Vaughan,
of Birmingham aforesaid, Manufacturers and Copartners, do hereby declare
the nature of the said Invention for "A NEW OR IMPROVED STRAP OR BAND
FOR WORKING STAMPS, RAISING WEIGHTS, AND TRANSMITTING POWER GENERALLY,"
to be as follows:-
Our Invention consists of a strap or band made of a thin strap or strips of
iron, copper, brass, or such other metal or alloy as combines sufficient strength
with the requisite elasticity, that is to say, an amount of elasticity which will
permit of the said band working over a pulley without taking a permanent set.
When more than one strip is employed, we rivet the strips together, either end

page_text: to end, or strip upon strip; the junctions in the latter case being arranged so
that no two shall coincide. The metallic strip or strips may be covered or
combined with gutta percha, india-rubber, or other flexible material.
In working stamps by our Invention, the band is attached at one end to the
hammer, and the other end passes over a pulley made to rotate by steam or
other power. By pulling the end of the band by a cord or chain attached
thereto, or otherwise, the friction of the said band upon the pulley causes the
pulley to carry up the band and raise the hammer. By liberating the band it
springs into such a shape as to lose its hold on the pulley, and the hammer
falls without obstruction. For raising minerals out of mines, and for raising
weights and transmitting power generally, our new or improved band or strap
is used as the ordinary chain, rope, leather, or gutta porcha band.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Vaughan, William James Vaughan, and Richard
Vaughan in the Great Seal Patent Office on the 5th May 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we. CHARLES
VAUGHAN, of Birmingham, in the County of Warwick, and WILLIAM JAMES
VAUGHAN, of Birmingham aforesaid, and RICHARD VAUGHAN, of Birmingham
aforesaid, Manufacturers and Copartners, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of November, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Charles Vaughan, William James Vaughan, and Richard Vaughan, Her
special licence that we, the said Charles Vaughan, William James Vaughan,
and Richard Vaughan, our executors, administrators, and assigns, or such
others as we, the said Charles Vaughan, William James Vaughan, and Richard
Vaughan, our executors, administrators, and assigns, should at any time ngreo
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 "A NEW OR IMPROVED STRAP OR
BAND FOR WORKING STAMPS, RAISING WEIGHTS, AND TRANSMITTING POWER GENE-
BALLY," upon the condition (amongst others) that we, the said Charles
Vaughan, William James Vaughan, and Richard Vaughan, our executors or
administrators, by an instrument in writing under our or their hands and

page_text: seals, or under the hand and seal of one of us or them, 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 we, the said Charles Vaughan, William James
Vaughan, and Richard Vaughan, do hereby declare the nature of the said
Invention, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement thereof,.
that is to say-
Our Invention consists of a strap or band made of a thin strip or strips of
iron, copper, brass, or such other metal or alloy as combines sufficient strength.
with the requisite elasticity, that is to say, an amount of elasticity which will
permit of the said strap or band working over a pulley without taking a
permanent set. When more than one strip is employed we rivet the same.
together, end to end, or strip upon strip; the junctions in the latter case being
so arranged that no two shall coincide. The metallic strip or strips may be
covered or combined with leather, gutta percha, india-rubber, or other flexible
material. The said flexible materials may be connected with the metallic strip
or strips by rivetting, or in any other convenient manner.
Although our new or improved strap or band is applicable for the trans-
mission of motion in all cases where straps or bands of leather or gutta percha
are ordinarily employed, yet our Invention is more particularly applicable for
working stamps, and we have illustrated its application to a stamp in the
accompanying Drawing.
Figure 1 represents a front elevation, and Figure 2 a transverse vertical
section of a stamp, worked with a strap or band constructed according to our
Invention. a, b, c, is the strap or band, consisting of a strip of hoop iron or
other metal or alloy; the said strap or band passes over the pulley d, to which a
rotatory motion is communicated in the direction of the arrow (Figure 2) by
the pulley and band e, Figure 1, or otherwise. f is a handle attached to the
end a of the band or strap a, b, c; and 9 is the hammer of the stamp fastened
to the end c of the strap or band. When the end a is not pulled downwards, the
band does not lie close upon the pulley d, its elasticity causing it to assume a
curvature of larger radius than that of the said pulley d, the said strap or band
consequently only touches the pulley d in two or three places, as represented in
Figure 2, and the pulley d, in rotating, slips freely under the strap or band with
little friction. When, however, the end a of the band is pulled by means of the
handle f, the said band is made to bear upon the upper half of the pulley d,

page_text: and the friction of the said band upon the said pulley causes motion to be
transmitted to the band, and the hammer g thereby to be raised.
I
When the said hammer 9 has been raised to the requisite height, the work-
man loosens or slackens the handle f, when the elasticity of the strap or band
causes it immediately to assume the shape represented in Figuro 2; the strap
or band a, b, c, no longer "bites" the pulley d, but looses its hold on the said
pulley, the hammer 9 immediately falls without obstruction, and is again
raised by the workman pulling down the end a. The pulley d is kept in a
state of uniform rotation by steam or other power.
For raising minerals out of mines, and for raising weights and transmitting
power generally, our new or improved strap or band is used as the ordinary
chain, rope, leather, or gutta percha bands are used.
Having now described the nature of our said Invention, and the manner of
carrying the same into effect, we wish it to be understood that we do not limit
ourselves to the precise details herein described, and illustrated in the Drawing,
as the same may be varied without departing from the nature of our said
Invention; but we claim as our Invention the new or improved strap or band
for working stamps, raising weights, and transmitting power generally, berein-
before described, and illustrated in the accompanying Drawing, that is to say,
a strap or band made of a strip or strips of metal or metallic alloy, either alone
or in combination with leather or other flexible material.
In witness whereof, we, the said Charles Vaughan, William James
Vaughan, and Richard Vaughan, have hereunto set our hands and
seals, this Twenty-seventh day of April, in the year of our Lord One
thousand eight hundred and fifty-soven.
