PROVISIONAL SPECIFICATION.
An Improved Belt Fastener or Appliance for Connecting the Ends of
Driving-belts and the like.
I, WILLIAM TATTERSALL, of 8, Southfield Square, Bradford in the County of
York, Engineer, do hereby declare the nature of this invention to be
follows:-
as
This invention relates to an improved belt fastener or appliance for connecting
together the ends of leather, cotton, rubber and other driving belts and the like, and
the object of the invention is to provide a simple and ready method of securely
joining together said ends without cutting, piercing or otherwise weakening the
belt.
The said improvements consist of the arrangements hereinafter described in which
a wedge or key is employed to fix the said ends between jaws or rollers in such a
manner that the tension of the belt tends to tighten such wedged ends between said
jaws or rollers.
•
For this purpose I employ a clasp of U section of suitable width at the opening to
enable it to be passed over the ends of the belt when they are placed side by side
and widening out inside to allow of the insertion of a wedge between such ends. It
will be readily seen that the tension of the belt tends to draw the wedged ends into
the narrow opening in the said clasp thus binding such ends securely in said opening.
Those portions of said clasp upon which the ends bear are preferably rounded at the
edges, and the said wedge is serrated or roughened in such a manner as to allow it
to be readily inserted between the ends but tending to retain it in position. The
said wedge may be inserted from the side or through a suitable opening in the
clasp.
The said clasp may be more or less modified in form and be constructed of stout
steel wire or formed in sections. Or a suitable link may be employed adapted to
receive the ends of the belt and a wedge driven between them.
Rollers may be mounted along each side of the opening in said clasp through which
the ends of the belt pass for each end to bear against, or two rollers linked together
may be employed and the ends of the belt wedged between them instead of employing
said clasp.

An Improved Belt Fastener or Appliance for Connecting the Ends of
Driving-belts and the like.
I, WILLIAM TATTERSALL, of 8, Southfield Square, Bradford in the County of York,
Engineer, 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 relates to an improved belt fastener or appliance for connecting
the ends of leather, cotton, rubber and other driving belts and the like, and the

page_text: The said improvements consist of the arrangements hereinafter described in which
a wedge or key 15 employed to fix the sand onds between jaws in such a manner
that the tension of the belt tends to tighten such wedged ends between said jaws.
For this purpose I employ a clasp of U section.of suitable width at the opening to
enable it to be passed over the end of the belt when they are placed side by side
and widening out inside to allow of the insertion of a wedge between such ends. It
will be readily seen that the tension of the belt tends to draw the wedged ends into
the narrow opening in the said clasp thus binding such ends securely in said opening.
Those portions of said clasp upon which the ends bear are preferably-rounded-at-the-
edges, and the said wedge is serrated or roughened in such a manner as to allow it.to be
readily inserted between the ends but tending to retain it in position. The said
wedge may be inserted from the side or through a suitable opening in the clasp.
The said clasp may be more or less modified in form and be constructed of. stout
steel wire or formed in sections. Or a suitable link may he employed adapted to
receive the ends of the belt and a wedge driven between them.
In order to fully describe the nature of my said invention reference is made to
the accompanying sheet of drawings forming a part of this specification in which
similar letters of reference indicate corresponding parts in each of the figures.
Figure 1, is a side view of my improved belt fastener in which the ends of the
belt are wedged between the sides of the link.
Figure 2, is a sectional view of the same, and
Figure 3, is a plan view.
Figures 4 and 5 are respectively a side view and a plan of a belt fastenor or clasp
of shaped or horseshoe section widening cut inside and having the, ends of the
bolt wedged therein.
Figure 6, is a side view of a wire clasp of similar horseshoe form.
Figure 7, is a larger perspective view of the serratod wedge shown in figure 4, and
Figure 8 is an elevation of the spiked wedge represented in the other figures.
Figure 9, is a transverse section of the latter figure through the line, y.
To fix the fastener represented in figures 1, 2 and 3, the ends B of the belt are
passed through the rectangular link A and are placed side by side with the wedge C
between them, then such ends are hammered or pressed together to cause the spikes e
to penetrate the belt and prevent the wedge working loose. Thus with the wedge
in this position as soon as the belt is stretched as represented the ends are firmly
wedged between the sides a of the link.
Figures 4 and 5 represent the form of fastener I preferably employ, when it is
necessary it should not project beyond the sides of the belt. To fix the fastener, the
wedge may be fixed between the ends B of the belt as before described and the
clasp A' slipped over such ends from one side." Or the ends of the belt may be
loosely passed inside between the rounded edges a¹ a' and the serrated wedge C
driven between them.
Instead of the clasp A' being made in one piece it may be made in sections or of
wire of any suitable section but to the form shown by A2 and a number of them
placed side by side over the ends of the belt according to the width required
Lfind no advantage in the combination of rollers with the fasteners for the ends
of the belt to bear against as mentioned in my provisional specification.
'
Having now particularly described and ascertained the nature of my said'Inven
tion, and in what manner the same is to be performed, 1 declare what I
claim is :
•
'
1. The combination with a clasp or link constructed to receive the ends of a belt,
of a suitable wedge adapted to be fixed between said ends, substantially as herein
shown and described and for the purpose specified.

2. A link shaped belt fastener having parallel opposite sides and adapted to have
"suitable wedge fixed.
