1, JOHN KEIL TULLIS of the firm of John Tullis & Son, St. Ann's Leather Works,
John Street, Bridgeton, Glasgow in the County of Lanark, North Britain, Tanner
and Currier do hereby declare the nature of this invention to be as follows:-
My Invention which relates to "An improved Clasp or Fastener is especially
applicable to driving Belts but may be used for other Belts or Bands, and consists in
employing a flat piece of metal-preferably copper-which has for its central part a
stronger piece of metal than the remaining parts & of oblong & oval form or
nearly so. From each end of said central part or Head is formed a point or pin
which are looped or bent over & inward until they form a straight line with the
end of the fastener Head the whole somewhat resembling a staple. These pins &
the central part of the fastener, are almost of the same length but may be made to
any convenient size. The pins are stronger & thicker at one end, and gradually
taper to a point & when in position in the Belt form a neat Joint.
From the construction & employment of these Fasteners the
Belt Joint is improved by reason of the light metal employed &
pulley whilst the strength is maintained & the disadvantages of
uneven run of the Belt joint on the pulley obviated.

COMPLETE SPECIFICATION.
An Improved Clasp or Fastener for Joining Together the Ends of
Leather or other Belting.
I, JOHN KELL TULLIS of the firm of John Tullis & Son, St. Ann's Leather Works,
John Street, Bridgeton, Glasgow, in the County of Lanark, North Britain, Tanner
and Currier 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 :-
My Invention relates to an improved clasp or fastener and is especially applicable
to driving belts but it may be used for other belts or bands.
It consists of a flat piece of metal, preferably copper with its two ends bent over
at right angles to the head or top part. The head or top part may be made of an
oblong or oval shape and is thicker or flatter than the two ends which gradually taper
to a point.
In order that my Invention may be properly understood and readily carried into
effect, I have hereunto appended an explanatory sheet of drawings, in the several
Figures of which corresponding parts are marked with the same letters of reference.
Figure 1, is a plan of my improved clasp or fastener before the ends are bent or
turned over.
Figure 2, is an elevation of the same shewing the ends bent or turned over.
Figure 3, is a plan of Figure 2.
Figure 4, is a view of the underside shewing the clasp or fastener as it would be
rivetted to the belt. (The foregoing Figures are all drawn to an enlarged scale.)
Figure 5, is a piece of belting shewing the ends rivetted together with my
improved clasp or fastener.

page_text: a, is the top or head of my improved clasp or fastener, while b, and c, are the
respective ends of the same. These two ends b, and c, are bent or turned over at
right angles to the top or head a, (Figure 2) when the whole fastener in a manner
resembles the form of a staple.
When the two ends b, and c, of my improved clasp or fastener have been forced
or otherwise put through the leather or other belting at the parts to be joined the
projecting parts of the two ends b, and c, are bent or turned in on the underside of
the belting as shewn at Figure 4, and these ends b, and c, being tapered to a point,
when in position in the leather or other belting form a neat joint.
From the construction and employment of these fasteners a decided want in the
manufacture of belting has been met, i.e., joints sewn with copper wire have always
been considered inefficient because of the narrow hold such has of the leather.
This clasp or fastener prevents most thoroughly the end of the speice from rising.
The same remark applies to all other speices whether sewn with lace, thread or other
fastening. The pliability of the belt joint and the running on the pulley is improved
by reason of the light metal employed while the strength is maintained and the
disadvantages of tapping and of uneven run of the belt-joint on the pulley obviated.
It is to be understood that these clasps or fasteners may be made of any size to
suit requirements.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The improved clasp or fastener as and for the purposes hereinbefore described and
shewn upon the accompanying sheets of drawings.
