PROVISIONAL SPECIFICATION.
Improvements in Belt Fasteners.
I, ISAAC JACKSON, of Glossop in the County of Derby, Belt Fastener
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to belt fasteners, and its objects are to enable the fastener
to be easily applied, to diminish thickening at the joints and projection of the
fastener beyond the surface of the belt, and to enable belts having their ends con-
nected by the fasteners to run smoothly over jockey or gallows pulleys and to run
equally well with either surface in contact with the driving or driven pulleys.
The fastener constructed according to these improvements consists of a piece of
wire bent twice at right angles so as to form a kind of staple, the extremities of the
limbs being re-curved, both in the same direction in planes parallel with each other
and perpendicular to the plane of the staple. At a short distance from each end of the
belt two holes are formed in such positions that the legs of the staple may pass
through them, and the ends of the belt lie in the curved parts of the limbs. On
one of the ends of the belt, two more holes are formed into which the hooks
may pass.
In the case of textile belts, I may use two perforated flanged plates, one for each
end of the belt and pass the limbs of the fastener through the perforations in the
plates as well as through the holes in the belt. In this case, the hooks may be
dispensed with, and the ends of the limbs may be secured by means of a pin passing
through them or otherwise, but the fastener will project from the surface of the belt
to some extent.
Instead of using the staples constructed as herein before described, I may employ
headed pins or the like, each of which corresponds with one leg of the staple, or I
may form the staples with three or more limbs each.
As many of the fasteners are employed in making a joint as may be required by
the width of the belt.

Improvements in Belt Fasteners.
I, ISAAC JACKSON, of Glossop in the County of Derby, Belt Fastener
Manufacturer, 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 :-
The objects of this invention, which relates to belt fasteners, are to enable the
fasteners to be easily applied, to diminish thickening of the joints and the projection
of the fastening devices from the surface of the belt, and to enable belts provided
with the improved fasteners to run more smoothly over gallows and jockey pulleys,
A fastener constructed according to this invention may be duplex and consist of
a piece of wire bent twice at right angles so as to form a kind of staple the
extremities of the limbs of which may be recurved to engage with the belt or be
provided with holes through which cotters, pins, or the like may be passed to secure
the fastener in place. The limbs are also bent or curved in planes parallel with
each other and perpendicular to the plane of the staple. Or the fastener may be
single, corresponding with one limb only of such a staple.

page_text: At a short distance from each end of the belt holes are formed for the fasteners
in such positions that the limbs may pass through the holes and the ends of the belt
lie in the curved parts of the limbs. More than one of the staples or limbs may be
employed to make a single joint.
In the case of textile driving belts, I may add to the fastener one or two
perforated plain or flanged or toothed plates or washers, the limbs being passed
through the perforations as well as through the holes in the belt. Such a plate or
plates or washers may also be used with other belts especially when only one
fastener is employed to make a joint.
I will more particularly describe my said invention with reference to the accom-
panying drawings in each of the figures of which similar parts are denoted by
similar letters of reference.
As illustrated by Figures 1 and 2 which represent a plan and side view
respectively the ends A and B of the belt are connected by the staples C the ends
of the limbs of which are recurved or bent to engage with the belt. This
recurvature may be greater than that shewn but it will generally be found sufficient
to flatten the ends and turn them at right angles or thereabouts. These flattened
ends may be substituted if desired by hooks which penetrate into the substance of
the belt. Two perforated plates J, K, are shewn in the drawings but these plates
may if desired be dispensed with especially if more than one fastener be used in
making the joint, or if the belt is of a non-textile material. It is also preferred
as shewn in these and in succeeding drawings to flatten the bridge or that part of
the staple which connects the limb, instead of leaving it in its original circular
section. A better bearing surface is thus formed for the back of the staple.
As shewn by Figures 3 and 4 which illustrate similar views to Figures 1 and 2,
the ends of the limbs instead of being recurved are perforated or provided with
holes through which the split pin or cotter L is passed to secure the staple in place.
The two plates J K are similar to those illustrated in the preceding figures but
many variations may be introduced in their forms, as for instance, they may be
flanged or toothed along one or both edges.
Figures 5 and 6 illustrate the application of the fasteners such as are shewn by
Figures 1 and 2 to a wider belt. In such belts two or more of the staples C may
be arranged preferably in alternately opposite directions and the necessity for the
use of the plates ceases to exist although they may be employed as a precautionary
measure if desired.
Figures 7 and 8 shew in plan and side view respectively in what manner the
fastener may be used in substitution for a buckle with narrow belts. The ends or
one of the ends of the belt is or are provided with a series of pairs of holes, into
any pair of which the limbs of the fastener may be inserted. The fastener is
inserted through the pair of holes next to one end of the belt, and through the
pair nearest to the required length in the other end. The loose end falls over the
fastener as shewn by Figure 8 and may be fastened down by a pin stud lace or
other convenient device. This fastener is more readily applied and adjusted than
an ordinary buckle and possesses the advantage that no part of it projects beyond
the edge of the belt to come into contact with the strap forks or with the operatives.
In this application of the fastener one plate K is shewn placed under the bridge of
-the staple.
The fastener may be further modified by using single limbs separately. In this
case each end of the limb may be similarly recurved or hooked or one end of each
limb may be formed with a head or equivalent device.
Figures 9 and 10 are representations of a plan and section respectively of a joint
made with fasteners consisting of a single limb. In this case each end of the
fastener C is similarly formed and the illustration shews its application to the
adjacent edges of two belts.
A similar application of the fastener is shewn in Figures 11 and 12 but in this
case one end of each fastener is made larger than the other. This fastener is
separately illustrated in plan by Figure 13.

page_text: A further modification of the single limb fastener similarly applied to the
contiguous edges of two adjacent belts is illustrated by Figures 14, 15, 16 and 17.
Figure 14 is a plan of the fastening and joint, Figures 15 and 16 are sections, and
Figure 17 is a view from underneath. As will be seen on reference to the drawings
the fasteners C are provided at each end with a hook E or E' which penetrates
the substance of the belt. Figure 15 is a section through the belts and the pulley
over which they pass. The fastener C does not come into contact with the pulley D,
but, owing to its form and rigidity is raised from it leaving a clear space out of
contact with the pulley between the two points F and F¹. Figure 16 is a section
shewing the same belts and fastener in contact with a jockey pulley D' the opposite
side of the belt to that shewn in Figure 15 being in contact with the pulley. The
fastener which is capable of a certain amount of distortion or springing, allows the
edges of the belts to come into contact with the pulley at the point between
the points G and G. The hooked part E may be used with each form of the
fastener.
It will of course be understood that I do not limit myself to the precise means
shewn for preventing the fasteners being withdrawn from the belt and which consist
either in a recurved part or a hook as it is obvious that other devices such as a
screwed end with a nut fitting thereon may be employed. The forms shewn are simply
those which I prefer to employ and a fastener illustrated as used in some particular
form of joint will of course be equally suited for use in another form.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is:-
1. A belt fastener consisting of a piece of wire bent twice at right angles to
form a kind of staple, having both its limbs curved or bent and having the ends of
its limbs turned recurved or hooked to engage with the belt, substantially as
herein before described and as illustrated by the accompanying drawings.
2. A belt fastener consisting of a piece of wire bent twice at right angles to form
a kind of staple, having both its limbs bent or curved in the same direction and
having the ends of its limbs provided with means such as pins cotters or nuts to
secure the fastener in the belt, substantially as hereinbefore described and as
illustrated by the accompanying drawings.
3. A belt fastener consisting of a piece of wire the central portion of which is
bent or curved, and the ends of which are turned recurved or booked to engage
with the belt, substantially as herein before described and as illustrated by the
accompanying drawings.
