page_text: We, FREDERICK HENRY KEANE, of Cappoquin Foundry, in the County of
Waterford, Ireland, Engineer, and DAVID WILSON, of Main Street, Cappoquin,
in the County of Waterford, Ireland, Iron Turner, do hereby declare the nature of
this invention to be as follows:-
..
Our invention relates to a device whereby the two ends of a belt or strap may
be conveniently secured together, so as to resist any ordinary working strain which
may be transinitted by the belt to the joint.
,
Our fasterier consists of two lever-grips; conveniently made of malleable cast iron
or other suitable material, in each of which one jaw is provided with serrated teeth,
and there is a tail projecting approximately at right angles to the said jaw, forming
a right angled lever. The width of the said lever grips is the same as that of the
strap to which they are applied. The back of the said jaws, opposite the angle
formed by the jaw and the tail, is provided with a recess, in which fits a link,
made of malleable cast iron or other suitable material, the link being of suitable
shape (such as a rectangular parallelogram) so as to embrace the outside of the
grips, and the strap ends between them. The section of this link may be either
round, oval, or triangular, and it may if desired be made in more than one piece.
To couple or fasten up the belt, the short serrated jaws of the lever grips are put
inside the link which fits into the aforesaid recess or groove at the back of the
jaws. The two ends of the belt are then pressed in between the faces of the
aforesaid jaws, the serrations on the latter being so formed as to readily allow
the belt to be pushed in from the under side, but to bite into and seize the ends of
the belt when the working strain tends to withdraw the ends. By lifting the tails
of the lever grips, the jaws are then forced home on to the strap ends.
•
When the body of the belt or strap is extended ready for work, the fastened
ends stand approximately at right angles to the body of the strap, and the body of
the strap, in thus extending, presses upwards the tails of the lever-grips which rest
upon the body of the strap on either side of the joint, and thus firmly press the
serrated jaws of our fastener into the ends of the strap which they secure.

We, FREDERICK HENRY KEANE, of Cappoquin Foundry, in the County of
Waterford, Ireland, Engineer, and DAVID WILSON, of Main Street, Cappoquin,
in the County of Waterford, Ireland, Iron turner, 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 relates to a device whereby the 'two ends of a belt or strap may
be conveniently secured together so as to resist any ordinary working strain which
may be transmitted by the belt to the joint.
Figure 1 is a sectional elevation through our belt fastener with the belt in
position.
Figure 2 is a perspective view of the same.
Figure 3 is a perspective detail of one lever grip of my fastener.
Figure 4 is a detail of the link used in conjunction with the lever grips of our
device.
Our device consists of two lever grips A A (one being shown detached in detail
in figure 4) which may be constructed of malleable cast iron, or other suitable
material, whereof one jaw B is serrated and the other part C of the lever-grip is
continued into a tail of considerable length, approximately at right angles to the
serrated jaw. A recess D is provided at the back of the lever jaw, into which fits
the embracing link E, of malleable cast iron or other suitable material, and which
is of suitable shape, (such as a rectangular parallelogram) so as to embrace both
gripping jaws, and to form a point of resistance on which the lever-grips can turn.
The said grips extend conveniently for the whole width of the strap or belt.
The section of the link may be either round oval, triangular or of other convenient
shape.
'
To couple or fasten the belt F, the short ends of the lever grips A. A are put
inside the link E, the link fitting into the aforesaid recesses D of the grips. The
ends of the belt F are then pressed in between the jaws from the under side, and
the serrated jaws are pressed forcibly against the ends of the strap by the pressing
asunder of the tails C of the lever grips, either by hand or by the natural action of
the strap when it is extended ready for working. The body of the strap is in such
case, extended perpendicularly to the joint, and thus presses upwards with great
force upon the tails of the lever-grips, which lie upon the extended body of the
strap, so as to ensure a very forcible and secure grip upon the ends of the strap.
The serrations on the jaws of the gripping levers are made so that the strap can
readily enter from the under side, but is seized upon its return. The link E may
be made, if desirable, in more than one piece.
We are aware that cam locking jaws have been applied to a similar purpose as
our device; but my apparatus depends for the success of its action upon the great
pressure of the extended body of the strap on either side of the joint upon the tails
of our lever-grips.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, I declare that what
we claim is:-
The construction of a belt or strap fastener, consisting of two lever-grips, in
which a serrated jaw and a prolonged tail are approximately at right angles to
each other, the said lever-grips being free to move upon the bars of an embracing
link, the grip of the jaws being effected by the pressure of the extended strap,
when in work, upon the prolonged tails of my lever grips, substantially as
described.
