We, PETER CALDWELL of Horse Market Street, Warrington, in the County of
Lancaster, and JOHN HENRY TURNER of Golborne Street, in the same town, Manu-
facturer and Traveller respectively, do hereby declare the nature of this invention to
bo as follows:-
This invention is designed to produce a belt fastener that shall not weaken the
power of the belt. All other belt fasteners almost are designed on the principle of
passing the fastener through the two ends of the belt, so as to hold them together.
Lacing, hitherto, has been most effective, because, in addition to the laces going
through the belt and so holding it by opposition to a shearing strain, the laces also
tightly compress one end of the belt against the other and so form a frictional
resistance also. Our invention is designed to get the full effect of that frictional
resistance, without weakening the belt by cutting through it at the part where the
belt would be likely to tear.
We form two angle irons, preferably of malleable cast iron, with very rounded
angle and preferably also with cross flanges uniting the two flanges of each angle
iron. The ends of the belt are placed between these two angle irons and bolts passed
through the belt and holes in the angle irons, and the whole is screwed tightly
together. As the two angle irons hug the belt beyond the bolt hole, it is almost
impossible for the belt to tear at the bolt holes. It must tear, if it tears at all,
beyond the angle irons at the bend or other part of the belt, and as the bend is made
a very gradual bend, it is hardly likely to break through, as at this particular point
there is absolutely no wear.

We, PETER CALDWELL of Horse Market Street, Warrington, in the County of
Lancaster, and JOHN HENRY TURNER, of Golborne Street, in the same town,
Manufacturer and Traveller respectively, 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 is designed to produce a belt fastener that shall not weaken the
power of the belt. All other belt fasteners almost are designed on the principle of
passing the fastener through the two ends of the belt, so as to hold them together.
Lacing, hitherto, has been most effective, because, in addition to the laces going
through the belt and so holding it by opposition to a shearing strain, the laces also
tightly compress one end of the belt against the other, and so forin a frictional
resistance also. Our invention is designed to get the full effect of that frictional
resistance, without weakening the belt by cutting through it at the part where the
belt would be likely to tear.
Referring to the drawings
:-
Figure 1 is a plan view of one of our improved fasteners as applied to a belt.
Figure 2 end elevation of same.
Figure 3 side elevation of same.
In these A A represent two angle pieces, preferably of malleable cast iron, and
each formed with very rounded angle, and preferably also with cross flanges or
webs a a at intervals uniting and strengthening the two flanges thereof. B represents
the belt, the two ends of which are bent outwards at right angles and are together
placed between the two angle pieces. Bolts C Caro passed through holes in the belt
and angle pieces, and the whole screwed tightly together by means of nuts D D.
Bosses or washers bb may, with advantage, be provided for the bolt heads and nuts to
bear against.
As the two angle pieces hug the belt beyond the bolt holes at 61 61, there is very
little danger of the belt tearing at the said holes. The angle pieces being made with
very rounded angles, the liability of the belt to break at these points is greatly
diminished, and there is practically no wear at the said points. If desirable, the
faces of the pieces A, may be roughened or covered with small indentations or
projections, in order to increase the friction between them and the belt ends. It is
evident that many tightening mechanisms, the mechanical equivalent of the bolts CC,
might be used for cramping together the angle pieces A. We, therefore, wish it to
be understood that we do not confine ourselves to the use of bolts alone for producing a
the necessary pressure. Also, the form of the pieces A, may be varied considerably,
without departing from the principles of our invention.

page_text: 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 :-
1. A fastener for belts or driving bands consisting of two angle-pieces placed
back to back with rounded angles to avoid chafing (and preferably with strengthening
webs) and pierced with opposing holes through which tightening bolts or their
equivalent may be passed, substantially as and for the purposes set forth.
2. An improved joint for a belt or driving hand depending wholly or mainly for its
strength on the frictional resistance created between the bent ends thereof, by
cramping or compressing them together by cramps on the outer face of the belt or
band ends, the said compression being produced by bolts or other tightening
mechanisms causing a strong pressure to be exerted between the cramps and the
belt ends, pressing the latter against each other in their bent position, substantially
as described.
