THEY DIONAL DIBUITIVATION,
Improvements in the Splices or Joints of Leather Belting Used for
the Transmission of Power.
We, JOHN KEIL TULLIS of the firm of John Tullis and Son St. Anns' Leather
Works, Bridgeton, Glasgow, in the County of Lanark, North Britain, Leather belt
manufacturer, and WILLIAM RISK MALCOLM, manager to the said John Tullis and
Son, above described, do hereby declare the nature of our invention for "IMPROVE-
MENTS IN THE SPLICES OR JOINTS OF LEATHER BELTING USED FOR THE TRANSMISSION
OF POWER to be as follows :-
"
This Invention which relates to improvements in the splices or joints of leather
belting used for the transmission of power, consists as follows-
The splice or joint is made by cutting with an incline or slope the surfaces of the
two belts parallel the one to the other, or in other words paring down the end of each
strip in such a manner, that when overlapped, one uniform thickness of belting is
maintained. The overlap is about 7" long but may be varied. One strip has the
inside or rough part of the leather cut away, whilst the other has the outer surface
or smooth side removed, so that the spliced belt presents a continuous rough inner
surface, and a continuous smooth outer surface.
A shaving say an inch or other suitable length of the outer or smooth surface is
then removed from the extreme or thin end of the one strip, and a flap of an equal
length of the smooth or outer skin is made in the thick end of the other strip just
beyond the part already cut away.
The flap is then raised, the two tapered ends of the strips placed in position, the
one overlapping the other, and the extreme or thin end of that strip which forms the
outer part of the belt at the joint placed under the before mentioned flap; the two
pieces are then cemented together.

page_text: The flap is then turned down and similarly secured to the top of that strip which
forms the outer part of the belt at the splice covering the extremity of the same, so
that when the belt is running both the upper and lower ends of the splice run to the
pulley or guide forks, without any chance of opening by contact because the flap
covers the upper part of the joint in such a way as to run in the same direction as
the lower side of the splice. The whole forms a neat substantial joint, and in no
way interferes with the regularity in the thickness of the belt.

Improvements in the Splices or Joints of Leather Belting Used for
the Transmission of Power.
We, JOHN KEIL TULLIS of the firm of John Tullis and Son St. Ann's Leather
Works, Bridgeton, Glasgow, in the County of Lanark, North Britain, Leather belt
manufacturer and WILLIAM RISK MALCOLM, manager to the said John Tullis and
Son above described do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
Our Invention which relates to improvements in the splices or joints of leather
belting used for the transmission of power, consists as follows―
The splice or joint is made by cutting with an incline or slope, the thickness of the
two belts, parallel the one to the other, or in other words paring down the end of
each strip in such a manner, that when overlapped one uniform thickness of belting
is maintained. The overlap is about 7" long, but may be varied. One strip has the
inside or rough part of the leather cut away, whilst the other has the outer surface
or smooth side removed, so that the spliced belt presents a continuous rough inner
surface and a continuous smooth outer surface.
A shaving say an inch or other suitable length of the outer or smooth surface is
then removed from the extreme or thin end of the one strip, and a flap of an equal
length of the smooth skin is made in the thick end of the other strip just beyond the
part already cut away..
The flap is then raised, the two tapered ends of the strip placed in position, the
one overlapping the other, and the extreme or thin end of that strip which forms the
outer part of the belt at the joint placed under the beforementioned flap, the two
pieces are then cemented together.
The flap is then turned down and similarly secured to the top of that strip which
forms the outer part of the belt at the splice covering the extremity of the same, so
that the end of the flap on the outside of the belt, and the end of the splice on the
inside, both point in the same direction, and when the belt is running, run from the
pulley or guide forks, thereby preventing any chance of the splice from being forced
open by the said ends coming in contact with any projecting part of the pulley or
guide forks. The whole forms a neat substantial joint, and in no way interferes with
the regularity of the belt.
In order that our Invention may be properly understood and readily carried into
effect, we will now proceed to describe the drawings hereunto annexed.
Figure 1, is a side view of a portion of one of the strips of belting to be jointed,
the end of the strip being pared down and provided with a flap as arranged, according
to this Invention.
Figure 2 is a side view of a portion of the other strip of belting to be jointed with
the end of the strip pared down according to this invention.

page_text: Figure 3, is a longitudinal section of the belt joint, constructed according to and
constituting this Invention, and Figure 4, is a face view of the same.
In these figures the same letters of reference indicate the same parts.
According to the arrangement illustrated in the said figures, the splice or joint is
made by cutting with an incline or bevel, the thickness of the belt at the end of the
strips A and B, as shewn at C Figure 1, and C, Figure 2, the strip A, having by
preference the outer or smooth surface pared off, whilst the strip B, has the inner
or rough surface removed, so that the spliced belt presents a continuous outer smooth
surface D, and a continuous inner rough surface E. A paring equal to the breadth
of the belt, and of about an inch in length is then taken from the smooth surface at
the extreme or thin end of the strip B, as shewn by the dotted lines at F, Figure 2,
and a flap G, of a length equal to that of the paring F, is made in the strip A.
The strips A and B, are then jointed or spliced by inserting the thin end of the
strip B, under the flap G, of the strip A, and cementing the said strips together at
the pared surfaces Cand C, the flap G, is then turned down and similarly secured to
the strip B, at the pared surface F, so that the whole forms a neat substantial joint
as shewn at Figures 3 and 4, and in no way interferes with the regularity of the belt.
It is to be understood however that the flap G, may be made on the rough surface of
the leather if desired, in which case the belt as shewn on the annexed drawings would
present a continuous rough surface D, and a continuous smooth surface E.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed we declare that what we
claim is―
First. The general arrangement and combination of parts constituting the improved
splice or joint for leather belting, substantially as hereinbefore set forth with reference
to the annexed drawings.
Second. In the splices or joints of leather belting, the flap G, of the strip A, in
relation to the pared surface F, of the strip B, substantially as, and for the purposes
herein before set forth with reference to the annexed drawings.
