IMPROVEMENTS IN LEATHER DRIVING BANDS, AND IN PROVISIONAL SPECIFICATION THE MACHINERY EMPLOYED IN THE MANUFACTURE. THEREOF
Year: 1875

page_text: LETTERS PATENT to George James Booth, of the Firm of Oliver and
William Ormerod, of Rochdale, in the County of Lancaster, for
the Invention of "IMPROVEMENTS IN LEATHER DRIVING BANDS, AND IN
PROVISIONAL SPECIFICATION left by the said George James Booth
at the Office of the Commissioners of Patents, with his Petition, on
the 14th December 1875.
I, GEORGE JAMES BOOTH, of the Firm of Oliver and William Ormerod,
of Rochdale, in the County of Lancaster, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN LEATHER. DRIVING BANDS,
AND IN THE MACHINERY EMPLOYED IN THE MANUFACTURE. THEREOF," to be as
follows:
-
My Invention relates to that class of leather driving bands or straps
which are composed of two thicknesses of leather with canvas or other
woven fabric cemented between them, the whole being fastened together

page_text: by longitudinal rows of copper or other metallic wire rivets, by means
of White's rivetting machine (Patents No. 368, A.D. 1864, & 2698
A.D. 1870) or any other similar rivetting machine.
The Invention is also applicable to the rivetted joints of single belting.
The great objection to driving bands or straps of this class has hitherto
been that owing to the projection of the metallic rivets on the inner side
of the band or strap a great loss of power is experienced by the slipping
of the strap upon the pulley, and the full power of the strap is never
obtained until the strap has been in use for a considerable time. Also
that the larger and better the "clinch" has been the greater has been
the projection, making the best work inferior in this respect to that
which has not been properly driven through the leather and clinched, a
good clinch being necessary to make the work permanent, which if it
projects must necessarily be partially worn away and weakened before
the strap comes down to its work.
In order to remedy the defect I countersink or recess the leather
upon the under side of the strap where the rows of rivets are to be
inserted, so that the ends of the rivets when clinched do not project
from the surface of the leather, but are countersunk therein, by which
means the face of the leather bears at once upon the driving pulley, and
no loss of power occurs.
The countersinking or recessing of the leather may be effected before
the rivetting operation by means of a pair of pressing rollers with
suitable projections, or in any other convenient manner, but I prefer to
effect the same at the time of rivetting and by means of the punch
which drives the rivets. For this purpose (instead of having a flat
broad anvil as hitherto used in White's machines), I form the anvil of
the rivetting machine with a narrow raised projection or pap.. This
projection or pap as each rivet is clinched forms a recess or countersink
on the under side of the leather where each rivet is clinched, so that
the rivet does not project beyond the surface of the leather; I also form
a circular or hemispherical recess in the anvil or plate for the purpose
of turning or clinching the rivet points with greater regularity and
certainty, thus making the work firmer and more durable.

filed by the said George James Booth in the Great Seal Patent
Office on the 9th June 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
JAMES BOOTH, of the Firm of Oliver & William Ormerod, of Rochdale,
in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of December, in the
year of our Lord One thousand eight hundred and seventy-five, in
the thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said George James Booth, Her
special license that I, the said George James Booth, my executors,
administrators, and assigns, or such others as I, the said. George
James Booth, 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 LEATHER DRIVING BANDS, AND IN
MACHINERY EMPLOYED IN THE MANUFACTURE THEREOF," upon the condition
(amongst others) that I, the said George James Booth, 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 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 George James Booth, 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 :-
My Invention relates to that class of leather driving bands or straps
which are composed of two thicknesses of leather, with canvas or other
woven fabric cemented between them, the whole being fastened together
by longitudinal rows of copper or other metallic wire rivets, by means

page_text: Having now described the nature and object of my said Invention I
wish it to be understood that I claim,—
Countersinking or recessing the leather upon the under side of the
strap, where the rows of rivets are inserted, substantially in the manner
and for the purpose above set forth, whether such countersinking is
effected previously to or during the rivetting operation.
And, Secondly. I claim the means or apparatus herein-before
described for effecting such object.
In witness whereof, I, the said George James Booth, have here-
unto set my hand and seal, this First day of June, in the year
of our Lord One thousand eight hundred and seventy-six.
