IMPROVEMENTS IN THE MANUFACTURE OR CONSTRUCTION OF DRIVING BELTS OR BANDS."
Year: 1880

page_text: LETTERS PATENT to John Tullis, of Glasgow, in the County of Lanark, North
Britain, for an Invention of "IMPROVEMENTS IN THE MANUFACTURE OR
CONSTRUCTION OF DRIVING BELTS OR BANDS."
PROVISIONAL SPECIFICATION left by the said John Tullis at the Office
of the Commissioners of Patents on the 6th August 1880.
JOHN TULLIS, of Glasgow, in the County of Lanark, North Britain. "IMPROVE-
MENTS IN THE MANUFACTURE OR CONSTRUCTION OF DRIVING BELTS OR BANDS."
The said Invention relates to improvements in the manufacture or construction
of driving belts or bands, and consists in forming them as hereinafter described
from small pieces or strips of leather.
Driving belts or bands have hitherto in some cases been made from separate
small pieces of leather cut into separate links or pieces, which are placed together
side by side in number in accordance with the width of band or belt to be made,
and so as to break joint, and secured by pins passed transversely through them.
Now according to this Invention, in place of forming belts or bands of pieces of
leather in separate links, I form them as follows:-I take long strips of leather equal in
width to the thickness of the belt or band to be made, and I form nicks or notches
at intervals in both their edges. I also punch holes through the strips from side to
side, and at equal distances apart, for the reception of fastening pins, as hereinafter
described. The notches in the edges of the strips are situated by preference midway
between every alternate pair of these pin holes. The strips thus prepared are
placed together side to side in number sufficient to form a belt or band of the
requisite width, the pin holes in each strip being coincident with those of all
the other strips, and the nicks breaking bond. Pins or bars are passed completely
through the aforesaid pin holes from side to side of the belt, one end of the said
pins or rods being formed with a head. When the pins are in position the ends
are turned down or rivetted, whereby they are secured in place and firmly unite
the component strips of the band. In place of forming the belt or band entirely of
strips, as described, the said strips may alternate with rows of separate pieces
or links of leather.
Belts or bands constructed according to my Invention are much stronger and
therefore more durable than those made in the ordinary manner from small pieces
of leather.

"IMPROVE-
JOHN TULLIS, of Glasgow, in the County of Lanark, North Britain.
MENTS IN THE MANUFACTURE OR CONSTRUCTION OF DRIVING BELTS OR BANDS."
My said Invention relates to improvements in the manufacture or construction
of driving belts or bands, and consists in forming them, as hereinafter described,
from strips of leather.
Driving belts or bands have hitherto in some cases been made from separate
small pieces of leather cut into separate links or pieces, which are placed together
side by side in number in accordance with the width of band or belt to be made,
and so as to break joint, and then secured by pins passed transversely through
them.
According to this Invention, in place of forming belts or bands of pieces of
leather in separate links, I form them as follows:-I take long strips of leather
equal in width to the thickness of the belt or band to be made, their length being
as great as is convenient, but in any case greater than the length of each link or
distance between the hereinafter mentioned nicks a. I form nicks or notches at
intervals in both their edges, as shown at a in Figures 1 and 2 of the accompanying
Drawing, which represent respectively side and top views of a portion of a strip. I
also punch or pierce holes b through the strips from side to side, and at, equal
distances apart, for the reception of fastening pins, as hereinafter described. The
notches a in the edges of the strips are situated by preference midway between
every alternate pair of these pin holes b, as shewn in Figure 1. The strips thus
prepared are placed together side by side, as shewn in Figure 3, which illustrates a
part of a length of belt or band, in number sufficient to form the requisite width
of belt or band, the pin holes b in each strip being coincident with those of all the
other strips, and the nicks a breaking bond. Pins or bars c are passed completely
through the aforesaid pin holes, from side to side of the belt, one end of the said
pins or rods being formed with a head. When the pins are in position the ends
are turned down or rivetted, whereby they are secured in place and firmly unite
the component strips of the band. Where the belts or bands are to be made greater
in length than the strips employed, the meeting of the ends of the said strips will
preferably be so arranged that as few of such meeting ends as possible are in one
transverse line.
In place of forming the belt or band entirely of strips, as described, the said
strips may alternate with rows of separate pieces or links of leather.
Belts or bands constructed according to my Invention are much stronger and
therefore more durable than those made in the ordinary manner from small pieces
of leather.
Having now described and particularly ascertained the nature of my said
Invention, and the system, mode, or manner in or under which the same is or
may be used or practically carried into effect, I would observe in conclusion that
I do not claim the making of bands or belts in separate links of leather, but what I
consider to be novel and original, and therefore claim as the Invention secured to
me by the hereinbefore in part recited Letters Patent is,-
The improvements in the manufacture or construction of driving belts or bands,
consisting in forming them of strips of leather of greater length than the length of
each link, or of the space between two alternate pins, nicked at the sides and

page_text: connected together as hereinbefore described, or in forming them partly of such
strips in combination with short or separate links, as hereinbefore set forth.
In witness whereof, I, the said John Tullis, have hereunto set my hand
and seal, this Fourteenth day of January, in the year of our Lord One
thousand eight hundred and eighty one.
JOHN TULLIS. (L.S.)
