Year: 1857

page_text: LETTERS PATENT to Edward Hirst Hudson, of Burley, in the Parish of
Otley, in the County of York, Worsted Spinner and Stuff Manufacturer,
for the Invention of "IMPROVEMENTS IN MEANS OR APPARATUS TO PREVENT
DRIVING STRAPS LAPPING ON THE SHAFTING WHEN THEY SHIFT OFF THEIR
PULLIES."
Sealed the 4th December 1857, and dated the 6th June 1857.
PROVISIONAL SPECIFICATION left by the said Edward Hirst Hudson.
at the Office of the Commissioners of Patents, with his Petition, on the.
6th June 1857.
I, EDWARD HIRST HUDSON, of Burley, in the Parish of Otley, in the County
of York, Worsted Spinner & Stuff Manufacturer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MEANS OR APPARATUS TO
PREVENT DRIVING STRAPS LAPPING ON THE SHAFTING WHEN THEY SHIFT OFF THEIR
PULLIES," to be as follows:-
The improvements consist in the application of thin wire or other rods dis-
tending between the supports of the shafting or in other suitable position, and
applying thereto adjustable hooks, one on each side of each puliey, to receive
the strap when from any cause it slips off its pulley, thereby preventing its
lapping on the shaft.

by the said Edward Hirst Hudson in the Great Seal Patent Office on the

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
HIRST HUDSON, of Burley, in the Parish of Otley, in the County of York,
Worsted Spinner and Stuff Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of June, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Edward. Hirst Hudson, Her special licence that I, the said Edward Hirst
Hudson, my executors, administrators, and assigns, or such others as I, the
said Edward Hirst Hudson, 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 "IMPROVE-
MENTS IN MEANS OR APPARATUS TO PREVENT DRIVING STRAPS LAPPING ON THE
SHAFTING WHEN THEY SHIFT OFF THEIR PULLIES," upon the condition (amongst
others) that I, the said Edward Hirst Hudson, 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 Edward Hirst Hudson, 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 thereof, that is to say :-
The improvements consist in the application of thin wire or other rods
distended between the supports of the shafting or in other suitable position,
and applying thereto adjustable books, one on each side of each pulley, to
receive the strap when from any cause it slips off its pulley, thereby preventing
its lapping on the shaft.
But that the nature of my said Invention, and in what manner the same is
to be carried into effect may be fully understood, I will proceed to describe the
Drawing annexed.

page_text: a represents part of a mill or other shaft, with a pulley 6 fixed thereon, for
the purpose, as is well understood, of giving motion by the band or strap c to
another pulley or drum, in connection with some machine or apparatus to be
driven by power.
It is well known that in loom sheds, and other places where such shafting
with driving pulleys thereon is applied, that the straps moved thereby are
liable to slip off the pulleys, when they very frequently lap or get coiled on to
the shafts, and when this happens the strain produced either breaks parts of
the machinery such strap is giving motion to or breaks such driving shafting
from its bearing, and it is to prevent such inconveniences which is the object
of my improvements. d, d, are hooks, suspended one on each side of a
pulley from the supporting shaft e, with their hooked ends d¹ within the
pulley. When from any circumstance the strap c slides from the surface of
its pulley b, in place of falling on to with a tendency, as explained, of becoming
lapped round the shaft a, it will fall on to a hook d, whereby such lapping on
to the shaft a will be prevented.
Having thus described the nature of my said Invention, I would have it
understood that I do not confine myself to the precise details shewn and
described, as these may be varied; but what I do claim is, the adaptation and
combination of means, as herein explained, to prevent driving straps lapping
on the shafting when they shift off their pulleys.
In witness whereof, I, the said Edward Hirst Hudson, have hereunto
set my hand and seal, this Thirtieth day of November, in the year of
our Lord One thousand eight hundred and fifty-seven.
Witness,
FRED W MOWBRAY.
EDWARD HIRST HUDSON. (L.S.)
