page_text: Improvements in Fasteners for Driving Belts.
I, DICK LITTLEWOOD, of Devonshire House, Surrey Street, Glossop, in the County
of Derby, Yeast Dealer, do hereby declare the nature of this invention to be as
follows:
This invention relates to hinged fasteners for driving belts and has been
especially designed with the object of ensuring a firm grip upon the belt ends,
of permitting the belt to be readily and quickly shortened, and of avoiding the
use of bolts and nuts and other parts which can become displaced when the belt
is in use.,
My improved fastener consists of two parts which are capable of being connected
together by a pin so as to form a hinge. Each part is composed of two plates
hinged together by a pin or pins so that the two plates may be folded over to
embrace one end of the belt, and on the inner face of each plate or part there are
fixed teeth or pins adapted to penetrate the belt. Opposite to each pin in one
plate there may be a hole or recess in the other plate into which the point of the
pin may enter after having passed through the substance of the belt. The holes
through which the two plates are connected together are formed in lugs or exten-
sions from the plates which are so constructed and arranged that the lugs or
extensions from one part fit between those of the other part of the complete
fastener. In these lugs or extensions there are bored, parallel with the holes
which receive the already hereinbefore described pins connecting the plates con-
stituting each part, other holes adapted to receive the pin by means of which
the two parts are connected together to constitute the complete hinged fastening.
The whole fastening is therefore constituted by two parts hinged together, each
part consisting of parallel hinged plates between which the ends of the belt are
held. The main hinge pin, passing through the same lugs or extensions as the
subsidiary pins, serves to lock the hinged plates of the separate parts firmly upon
the belt. The main hinge pin may be kept in place by a split pin passing through
it, by rivetting, by splitting the end of the pin or by a spring as is well understood.
in similar cases.

I, DICK LITTLEWOOD, of Devonshire House, Surrey Street, Glossop, in the County
of Derby, Yeast Dealer, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to hinged fasteners for driving belts, and it has been
especially designed with the object of ensuring a firm grip upon the belt ends;
of permitting the belt fastened by it to be readily removed or shortened; and of
avoiding the use of bolts, nuts, and other parts. which can become displaced from
the fastener when the belt is in use.
My improved fastener consists of two parts which are capable of being connected
together by a removable hinge pin. Each part is composed of two plates separately
hinged together by a pin or pins, so that the two plates may be folded over to
embrace one end of the belt, and engage it by teeth formed on the inner surfaces
of the plates. The holes through which the two plates are pinned together,
are formed in lugs or extensions from the plates, which are so constructed and
arranged that the lugs or extensions from one part fit between those from the other
part of the complete fastener. In these lugs or extensions there are bored, parallel
with the holes which receive the hereinbefore described pins connecting the plates
constituting each part, other holes adapted to receive the pin by means of which
the two parts are connected together to constitute the complete hinged fastener.
The fastener is therefore constructed of two parts, each of which consists of two
parallel plates hinged together by a subsidiary pin or by subsidiary pins, the
two parts being also hinged together by a main pin parallel with the subsidiary
pins. The main hinge pin thus serves to lock the parallel plates together, as well
as to form the centre of movement of the fastener.
The accompanying drawings, which will be hereinafter referred to, and in
each of the figures of which similar parts are denoted by similar characters,
illustrate my invention and will be hereinafter described.
Figure 1 represents a plan of the fastener as applied to the ends of a driving
belt.
Figure 2, shews a side elevation;
Figure 3, a longitudinal section; and
Figure 4, a section along the line y-y, Figure 2.
The four separate plates are numbered 1, 2, 3 and 4. The lugs from plate 1,
are 1 and 1b; those from plate 2, are 2 and 2h; those from plate 3 are 3 and 3b;
and that from plate 4 is 4. The plates 1 and 2 are hinged together by the two
subsidiary pins c and d, which respectively pass through the lugs 2 and 1", and
through 1 and 2. The plates 3 and 4 are hinged together by the subsidiary
pin e, which passes through the lugs 3, 4, and 3. The part composed of the
plates 1 and 2, is hinged to the part composed of the plates 3 and 4, by means
of the main pin f, which passes through all the lugs, parallel with the subsidiary
pins c d and e. The two parts are thus able to be moved about f as an axis when
the fastener passes over a pulley. If the pin f be withdrawn, the two parts A
and B are separable, and each of them may then be opened for the reception or
release of the belt ends C C¹. The inner surfaces of the plates are provided with
teeth, which penetrate and securely hold the belt ends as is indicated by
Figure 3.
It is advantageous to construct the fastener with a curvature of comparatively
large radius, as shewn by the Figures 2 and 3, as thereby strains are diminished
when the fastener runs over a pulley.

page_text: To prevent the pins coming out of the fastener, the outer subsidiary pins c d
may be headed at their inner ends (or at both ends) and these ends be fitted into
corresponding recesses in the sides of the lugs. The pin e, cannot come out when
the fastener is in use, but to keep it in place when the two parts of the fastener
are separated, the ends of the pin may be compressed into slight conical recesses
as indicated by Figure 4. The main pin f, may have, at one end, a head fitting
into a recess or slot in the end lug of the fastener, and be retained in place by
a flange g of the spring h, riveted or otherwise secured upon the upper plate 2.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A hinged belt fastener consisting of two parts hinged together by a main
pin, each part consisting of two parallel plates hinged together by a pin or pins
parallel with the main hinge pin, constructed substantially as hereinbefore des-
cribed and as illustrated by the accompanying drawings.
2. In a hinged belt fastener, an integral part consisting of two plates provided
with teeth on their contiguous surfaces and having lugs fitted with a pin or
with pins by which the plates are hinged together, and holes through which the
main hinge pin of the fastener is passed, constructed and arranged substantially
as hereinbefore described and as illustrated by the accompanying drawings.
3. A hinged belt fastener having a main hinge pin, and subsidiary co-axial
hinge pins parallel therewith, constructed substantially as herein before described
and as illustrated by the accompanying drawings.
