page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
KIBBLE, of Glasgow, in the Kingdom of Scotland, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Seventeenth day of February, in the seventh year of Her reign,
did; for Herself, Her heirs and successors, give and grant unto me, the said
John Kibble, Her especial license, full power, sole privilege and authority, that
I, the said John Kibble, my exors, adññiors, and assigns, or such others as I, the
said John Kibble, my exors, admors, or assigns, should at any time agree with,
and no others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, and also in
the Island of Jersey, Guernsey, Alderney, Sark, and Man, and in all Her
Majesty's Colonies and Plantations abroad, my Invention of "IMPROVEMENTS
IN TRANSMITTING POWER IN WORKING MACHINERY WHERE ENDLESS BELTS, CHAINS,
OR STRAPS ARE OR MAY BE USED;" in which said Letters Patent is contained a
proviso that I, the said John Kibble, shall cause a particular description of the
nature of my said Invention, and in what manner the same is to be performed,
to be inrolled. in Her said Majesty's High Court of Chancery with six

page_text: calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Kibble, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following Statement thereof, reference being had to
the Drawing hereunto annnexed, and to the figures and letters marked thereon,
that is to say :-
My Invention relates to those cases of transmitting power from one piece of
machinery to another were continuous rotatory motion of both axes is required;
and in those cases where endless bands or cords or gut have been heretofore
used. It is well known that the power of a steam engine or other first mover
is very commonly transmitted to a revoling axis or shaft, which gives motion
to machinery; and such transmitting of power is, by means of an endless strap
of leather or other material by means of a drum; and the power so transmitted
is again transmitted to various classes of machinery, such as spinning machinery,
looms, laths, and many others, as is well known; and in spinning machinery,
and some other descriptions of machines, various separate parts have indepen-
dent motion transmitted thereto by separate bands. The endless straps, bands,
or cords heretofore made, owing to the nature of the materials used, are very
likely to be quickly worn out and stretched, and otherwise give much trouble
in keeping them in order; and the so transmitting power, where continuous
rotatory motion is required, is thus rendered very expensive, and the machinery
is often stopped to apply fresh endless straps or bands, or to apply new ones.
Now, the object of my Invention is to obtain continuous rotatory motion, by
applying endless bands of thin metal, each band being so joined at its two ends
as to make the band endless, and in such manner that the joint may freely pass
the drums or pulleys used in the same manner as the other parts of the band,
it being important that whatever mode of joining the two ends be resorted to
that the joint should not interfere with the continuous passing of the joint on
the drums or pulleys, in the manner of ordinary endless bands, straps, or cords
now used for transmitting the continuous rotatory motion of one axis to another.
I believe the most simple mode of joining a metal strap into an endless strap
is to employ a single row of rivets across the strap, or the ends may be con-
nected by other convenient means. The metal I prefer to use is steel or brass,
of that quality known as guilding metal, but I do not confine myself thereto,
and I have usually employed sheet metal of about twenty-eight to thirty-two

page_text: of the wire guaze, making the endless straps wider and wider as more and more
power is to be transmitted thereby, in preference to making the metal endless
straps or bands of thicker metal. Figure 1 shows a part of an endless metal
band joined by one row of rivets across, as at a, a; and Figure 2 shows
another mode of making the necessary connection of the two ends of a metal
strap made endless in its action by joining the ends. In this case the ends
are elastically joined by means of the two pins 6, 6, which are joined together
by springs c, c, by which the driving pressure of the endless metal band or
strap will be controlled to the power of the spring joints thus used. It will
readily be understood, that by these means of joining the ends of metal straps
into endless belts will allow of the joints, as well as the other parts of the
endless belt, strap, or band, circulating freely round with the pulleys or drums,
and from one to the other, as endless bands of other materials have heretofore
done; and thus can parts of machinery requiring continuous rotatory motion
have the necessary power transmitted thereto by means of endless bands of
metal in place of other materials heretofore used, whereby the endless band
employed according to my Invention will be found to last longer and the
machinery less liable to be stopped than when other endless bands or straps or
cords have been used. I would remark that I am aware that bands of metal
have before been used in machinery where reciprocating motion has been
required to some moving part or parts, and bands or straps of metal have been
used for raising matters from mines and other places by winding on to a barrel;
and I mention these circumstances in order to state that I do not claim the use
of metal straps, belts, or bands for transmitting power to parts of machinery
generally. My Invention relates only to transmitting power to parts of
machinery where continuous rotatory motion is required from one axis to
another by means of endless bands. And I would wish it to be understood,
that what I claim is the mode herein described of transmitting power in working
machinery, whereby endless metal bands, straps, or belts are employed with the
ends so connected that they may not interfere prejudicially with the same
passing round against the surfaces of the drums, pulleys, or rotatory surfaces
used.
In witness whereof, I, the said John Kibble, have hereunto set my
hand
