PROVISIONAL SPECIFICATION.
An Improved Fastener or Device for Connecting the Ends of Driving
Belts or Straps.
I, THOMAS BROWN of 23 Broad Oak Street, Nottingham, Sawyer, do hereby
declare the nature of this invention to be as follows:-
My invention relates to fasteners or devices for connecting the ends of driving belts
or straps and the object of my invention is to provide a simple fastener which can be
readily applied and which will make a strong joint or connection.
My improved device consists of a screw-bolt having for its head a transverse bar or
rod. A similar bar or rod forms the nut which screws upon the other end of the
bolt.
In using my improved fastener corresponding holes are formed in the ends of the
belt to be united, the said holes being of just sufficient size to admit of the passage of
the bolt. The ends of the belt or strap are then turned outward bringing the inner
faces of the said ends together and the holes opposite each other. The bolt is then
passed through the two ends of the belt and the nut is screwed upon the projecting
threaded end of the said bolt until the ends of the belt are clamped between the
bars or rods forming the head of the bolt and the nut, the said head and nut being
turned parallel with the ends of the belt.
Any required number of my improved fasteners may be used, according to the
width of the belt or strap, and the size and strength of the said fasteners is varied
according to the size of the belt to which they are to be applied.

page_text: I, THOMAS BROWN, of 23 Broad Oak Street, Nottingham, Sawyer, 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:
This invention consists of a small bolt and nut the head and nut of which are formed
of transverse bars, that is to say are both parallelograms in shape, or nearly so, the
dimensions of the head or nut of a small sized fastener being about five eighths of an
inch in length, by about a quarter of an inch in width, and about one eighth of an
inch in thickness.
The head may be screwed on to and rivetted down on, one end of the bolt, or may
be merely rivetted thereto, or if preferred formed solid therewith. The bolt itself is
formed of a short length of wire or rod, and is screwed at the alternate end with a
thread to receive the nut.
The nut is tapped to receive the bolt end on which it is screwed when in use. Both
head & nut have their edges neatly rounded off so as not to cut the belt.
The bolt is bent so that the head and nut lie at an angle of about fifty degrees to
each other.
The angular form of the bolt enables the two ends of the belt to open as widely as
desirable when placed on the pulleys, and this bent form of bolt also ensures an even
bearing against the belt on the part of the head and nut of the bolt, the edges
of which are removed as before stated. Consequently a more efficient support to the
belt is secured without the danger of cutting into its substance, or of the belt itself
tearing, through unequal pressure on the part of the fastener.
My improved fastener is extremely easy to fix as it requires only a small round hole
in the belt which can be quickly made by a common bradawl or rhymer. It can be
made in various sizes and of different strengths.

invention and in what manner the same is to be performed I declare that what I
claim is :-
1. A machine-belt fastener consisting of a small bent bolt with head and nut of
parallelogramic outline, or nearly so but having rounded edges as herein described and
set forth.
