Year: 1869

page_text: LETTERS PATENT to Walter Cadogan, of 151, St. Anne Street,
Birkenhead, in the County of Cheshire, Practical Engineer, for
the Invention of "IMPROVEMENTS IN COUPLINGS FOR CONNECTING TOGETHER
THE ENDS OF DRIVING STRAPS OR BANDS."
Sealed the 29th October 1869, and dated the 13th May 1869.
PROVISIONAL SPECIFICATION left by the said Walter Cadogan at
the Office of the Commissioners of Patents, with his Petition, on
the 13th May 1869.
I, WALTER CADOGAN, of 151, St. Anne Street, Birkenhead, in the
County of Cheshire, Practical Engineer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN COUPLINGS FOR CONNECTING TOGETHER
THE ENDS OF DRIVING STRAPS OR BANDS," to be as follows:-
In order to connect together the two ends of a driving strap I attach
to the back of the belt at both of its ends by rivets, screws, and nuts or
otherwise a plate of metal. The back of each plate has standing out:
from it a row of studs, each stud carrying a pulley grooved around its.
circumference. Above the pullies is a bar or narrow plate to which the-

page_text: tops of the studs are fixed, and this bar or narrow plate is attached at
its ends to the two ends of the plate which is fixed to the end of the
strap. Each end of the strap is thus furnished with a row of pullics at
its back, and when it is desired to connect together the two onds of the
strap a cord or lacing strap is passed alternately around the several
pullies at the ends of the two straps, first round a pulley on one end of
the strap and then round a pulley on the other end of the strap, and
when the driving strap has been placed over driving pullies the strap
may be tightened upon them to any desired extent by tightening up this
cord. The ends of the cord can then be secured by tying knots upon
them of sufficient size not to pass between the plate and the bar attached
to its back. I prefer in all cases that the bar at one end of the belt
should carry one more pulley than the bar on the other end of the belt,
so that the pulleys on one bar shall come intermediate of the pullies on
the other bar. For narrow belts one end of the belt may carry one pulley
only, whilst the other end of the belt carries two pullies; or, for wider
belts, one end might carry two and the other three pullies, and so ou
according to the width of the belt.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Walter Cadogan in the Great Scal Patent Office
on the 13th November 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WALTER
CADOGAN, of 151, St. Anne St., Birkenhead, in the County of Cheshire,
Practical Engiucer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of May, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Walter Cadogan, Her special licence
that I, the said Walter Cadogan, my executors, administrators, and
assigns, or such others as I, the said Walter Cadogan, 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

page_text: COUPLINGS FOR CONNECTING TOGETHER THE ENDS OF DRIVING STRAPS OR BANDS,"
upon the condition (amongst others) that I, the said Walter Cadogan,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe
aud 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 Scal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Walter Cadogan, 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:-
In order to connect together the two ends of a driving strap I attach
to the back of the belt at both of its ends by rivets, scrows, and nuts or
otherwise a plate of metal. The back of each plate has standing out
from it a row of studs, each stud carrying a pulley grooved around its
circumference. Above the pulleys is a bar or narrow plate to which the
tops of the studs are fixed, and this bar or narrow plate is attached at its
ends to the two ends of the plate which is fixed to the end of the strap.
Each end of the strap is thus furnished with a row of pulleys at its back,
and when it is desired to connect together the two ends of the strap a
cord or lacing strap is passed alternately around the several pulleys at
the ends of the two straps, first round a pulley on one end of the strap
and then round a pulley on the other end of the strap, and when the
driving strap has been placed over driving pulleys the strap may be
tightened upon them to any desired extent by tightening up this cord.
The ends of the cord can then be secured by ticing knots upon them of
sufficient size not to pass between the plate and the bar attached to its
back. I prefer in all cases that the bar at one end of the belt should
carry one more pulley than the bar on the other end of the belt, so that
the pulleys on one bar shall come intermediate of the pulleys on the
other bar. For narrow belts one end of the belt may carry one pulley
only, whilst the other end of the belt carries two pulleys; or, for wider
belts, one end might carry two and the other three pulleys, and so on
according to the width of the belt.
And in order that my Invention may be fully understood and readily
carried into effect I have in the Drawings hereunto annexed shown two
couplings constructed according to my Invention.

page_text: In the arrangement of coupling shown in plan view at Figure 1, and
in edge view at Figuro 2, cach half of the coupling is composed of a
plate of metal a, which can be applied by rivets or by screws and nuts to
one end of the strap, the rivets or screws being passed through the strap
and through the holes a. b, b, are studs held at one end by the plato u,
and at the other end. by the narrower plate c, which is united above thic
plate a and is connected to it at its ends or is formed in one piece with
it; d, d, are the pulleys capable of revolving around the studs b; c is
the cord for lacing together the pulleys carried by the two halves of the
coupling.
Figure 3 shows an under side view, and Figure 4 an edge view of a
coupling similar to that shewn at Figures 1 and 2, except that the studs
or pins upon which the pulleys & are carried are prolonged on the
under side of the plate a and have screw threads cut on them to receive
nuts. To fix these couplings to the end of a strap or band the
prolongations of the pins bare passed through holes in the straps, and
the nuts are then screwed on to them. These couplings are also
provided with metal links or rings carried by pins h, h. When the ends
of the strap or band have been drawn together by drawing up the cord e
the end of the cord may be threaded through these rings and so add
strength to the coupling.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that what I claim
is, the constructing couplings for connecting together the ends of driving
straps or bands, substantially as herein described.
In witness whereof, I, the said Walter Cadogan, have hereunto
set my hand and scal, this Twelfth day of November, in the year
of our Lord One thousand eight hundred and sixty-nine.
