IMPROVEMENTS IN BELT FASTENERS
Year: 1885

page_text: I, CHARLES THOMAS POWELL of No 4 Cherry Street, Birmingham in the county
of Warwick Patent Agent do hereby declare the nature of this said invention for
IMPROVEMENTS IN BELT FASTENERS to be as follows:-
This invention relates to improvements in fastening the ends of driving belts
together and consists of cross pieces or bridges connected to each other at their ends,
and being further provided upon their surface with projecting teeth or spikes, in
alternate up and down directions. .
I form this my fastener with say three bridges, the lengthwise of these bridges
or bars lying crosswise to the lengthwise of the belt, and equal in length to about
the width of the belt.
In plan these bridges or bars are separated at a little distance from each other.
Upon the upper surface of the two outer bridges or bars I provide teeth or spikes,
and also arrange the position of these teeth, slantwise or inclined inwards towards
the central bridge. Again. Upon the underside of the central bridge I also
provide similar teeth or spikes, and also arrange their position slantwise or inclined
towards the centre of the bridge.
These fasteners may be made of malleable cast iron, or of rolled strip or sheet
iron, or steel, or they may be made of hard leather, or other suitable materials, with
iron or steel teeth either screwed into, or rivetted to, or otherwise attached thereto.
Looking at this my fastener sectionally (lengthwise of the belt) the central bridge
is higher than the two outside bridges, the ends which connect the bridges being
somewhat of a curved shape (in the case of being cast) or, the metal or other
material is bent between the bridges; this enables me to pass the end of the belt
over the outside bridge and thence under the central bridge, the same taking place
with the other end of the belt, or piece of belt, so that the two ends meet midway
in the centre of the central bridge. I then take a hammer (preferably of wood,)
and drive the belt on to the teeth or spikes both of the outer and central bridges,
and thus the connection is complete.
The action of this my fastener when in use tends to force the belt still further
on to the teeth, and so make it still more secure.
It is also applicable to all kinds of belting, whether of leather, cotton, or other
artificial material. It does not weaken the belts, by not requiring any holes cut
therein, and is cheap and durable.

page_text: I, CHARLES THOMAS POWELL of No 4 Cherry Street, Birmingham, in the county
of Warwick, Patent Agent, do hereby declare the nature of this invention for
IMPROVEMENTS IN BELT FASTENERS a communication to me from abroad by Nicolas
Qurin, of Kirchberg am Weihsel Lower Austria, 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 improvements in fasteners for fastening the ends of
driving belts together, and consists of cross pieces, bars, or bridges, connected to
each other at their ends, and being further provided upon their surface with
projecting teeth or spikes in-alternate up and down directions.
In order to describe this my invention more clearly I have appended hereunto an
illustrative sheet of drawings, upon which are figures and letters of reference, like
letters referring throughout to the same parts.
These fasteners may be made of malleable cast iron, or of rolled strip, or of sheet,
iron or steel, or other suitable metal, or, they may be made of hard leather, or other
suitable material, with iron or steel teeth, either formed upon, or screwed to, or
rivetted, or otherwise attached thereto.
In my drawings I have shewn two ways in which this my invention may be
carried out, that is, as made of malleable cast iron, and also of sheet iron or steel.
Fig. 1 is a perspective view of a fastener made of malleable cast iron.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is a sectional elevation of Fig. 2, upon line A―B.
Fig. 4 is a sectional elevation of Fig. 2 upon line A-B, shewing the two ends of
belt f, in position.
Fig. 5, shews how the end of the belt would be preferably shaped to enter the
fastener.
I form this my fastener with say, three bridges b, c, b, the lengthwise of these
bridges or bars lying crosswise to the lengthwise of the belt, and equal in length to
about the width of the belt.
In plan these bridges or bars are separated at a little distance from each other,
see Fig. 2. These bridges or bars are connected to each other by means of the
cheeks a, a, which are somewhat of segmental or curved shape, in side elevation
see Fig. 3. Looking at the sectional views Figs. 3 & 4, the central bridge is higher
than the two outside bridges, and upon the upper surface of the two outer
bridges b, b, I provide teeth or spikes g, and also arrange the position of these
teeth slantwise or inclined inwards towards the central bridge c. Also upon the
underside of the central bridge c, I provide similar teeth or spikes g, and also
arrange their position slantwise or inclined towards the centre of the bridge c.
Preferably I should prepare the two ends of the belt f, similarly in shape to that
shown in Fig. 5, the part which is made to pass into the fastener being narrowed to
allow of passing into the said fastener between the two cheeks a, a.
When making this my fastener from strip or sheet metal, I should cut out or.
stamp the plate to the required shape and size, with the teeth thereon, and flat;

page_text: then afterwards bend the teeth upwards or downwards, and to the desired angle,
and also bend and shape the cheeks a¹, a¹, each severally similarly as shewn at
Figs. 6 & 7.
Although I have not shewn drawings illustrative of this my invention made of
hard leather or other suitable material, still it will be readily seen that they may be
so made, having their teeth attached thereto which shall answer the same purpose
as for those already described.
The fastening of the belt is effected in the following manner:-The one end of
the belt being prepared as shewn at Fig. 5, is passed over the outer bridge b, and
under the central bridge c, until its end is level with the centre of the bridge c, I then
take a mallet (wood) or other suitable tool, and hammer the belt on to the up and
down spikes, as shown at Fig. 4. The other end of the belt is then passed into the
opposite side and treated in a similar way, when the union is complete, the teeth g,
penetrating or gripping into their ends in such a manner, that the teeth of the
bridge c, are forced into the outerside, and the teeth of the bridge b into the inner
side of the belt respectively, the running up side of the belt ends by these means
being extremely strongly united, and undoing or separating being almost impossible.
The chief merit of this fastener is, that it grips the belt ends from top and bottom
in such a manner that it not only grips by its teeth on both sides of the belt, but
such grip is intensified by their angularity or inclination, and further, the fact or
circumstance of the meeting of the two ends of the belts in the centre of the
bridge c, augments its gripping power.
This my fastener is applicable for large and small pulleys; has no tendency to
come off when running, but the rather to secure itself the more firmly, and it is
very light and easy to put on or take off; it does not weaken the belt by its
application, and is applicable to all classes of beltings; leather, cotton, or artificial
manufacture.
Having now particularly described and ascertained the nature of this my said
invention, and the manner in which it is to be performed, I declare that what
I claim is:-
The application or use of cross bridges or bars b, b & c, in belt fasteners, provided
with gripping teeth g, in alternate up and down directions, so that each side of the
belt may be gripped, reference being made to the accompanying description and
drawings.
