PROVISIONAL SPECIFICATION.
Improved Means for Piecing the Ends of Driving Straps or Belts.
WILLIAM THOMSON of Crompton Fold, Shaw near Oldham in the County of
Lancaster, Foreman Mechanic, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to afford a ready and efficient means for piecing
or uniting the ends of leather or other driving straps, or belts by rivetting
whereby a neat and strong joint is made and all strain is taken off the rivets.
For the purposes of my invention I cast in malleable iron a light plate of a
width somewhat less than that of the strap to be pieced and having two, four, or
more holes cast in it according to its width and having at the back of the plate a
projecting socket cast round each hole, the depth of the sockets being about equal to
the thickness of the strap or rather less. The upper edges of the plate are preferably
bevilled.
The ends of the strap or belt are cut to a "butt" joint and holes are punched
therein corresponding with the sockets on the back of the plato, so that when the
two ends of the strap are placed together edge to edge and the plate is laid over the
same a slight blow or pressure will force the sockets at the back of the plate into
the holes and thus unite the two ends together.
I provide also corresponding rivets which are preferably cast with small teeth or
projections at the back of the head, and these rivets being pressed in from the back
of the leather and rivetted on the face of the plate will complete the fastening. The
rivets may be either cast separate or cast in groups of two or more on a single plate
which answers for the hea Is of all the rivets.
It will be seen that there is no strain upon the rivets as all strain is borne by the
cast iron sockets, and the spikes or teeth on the back of the rivet heads will take hold
of the surface of the strap or belt and will be a further safe guard against the giving
way of the holes.

COMPLETE SPECIFICATION (AMENDED).
Improved Means for Piecing the Ends of Driving Straps or Belts..
I WILLIAM THOMSON of Crompton Fold, Shaw near Oldham, in the County of
Lancaster, Foreman Mechanic, 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 object of this invention is to afford a. ready and efficient means for piecing or
uniting the ends of leather or other driving straps or belts by rivetting whereby a neat
and strong joint is made and all strain is taken off the rivets.
For the purposes of my invention I cast in malleable iron a light plate of a width
somewhat less than that of the strap to be pieced, and having two, four, or more holes
cast in it according to its width and having at the back of the plate a projecting

page_text: hollow socket cast round or any other shape with or without one or more slots in the
said hollow socket the depth of the sockets to be about equal to the thickness of
the belting more or less as the case may be required or to the option of the
consumer.
The ends of the strap or belt are cut to a "butt" joint and holes are punched
therein corresponding with the sockets on the back of the plate, so that when the two
ends of the strap are placed together edge to edge and the plate is laid over the same
a slight blow or pressure will force the sockets at the back of the plate into the holes
and thus unite the two ends together.
I provide also corresponding rivets which are preferably cast with small teeth or
projections at the back of the head, and these rivets being pressed in from the back
of the leather and rivetted on the face of the plate will complete the fastening. The
rivets may be either cast separate or cast in groups of two or more on a single plate
which answers for the heads of all the rivets.
It will be seen that there is no strain upon the rivets as all strain is borne
by the cast iron sockets, and the spikes or teeth on the back of the rivet heads will
take hold of the surface of the strap or belt and will be a further safe guard against
the giving way of the holes.
I now refer to the accompanying sheet of drawings in which like letters of
reference indicate like parts in order that my invention may appear clear and
intelligible.
Fig. 1. is the plan of the inside underside of both forms of fasteners.
Fig. 2. is an-elevation a longitudinal section through a æ in A shewing first method
form of fastening-wherein 2 shews one end piece joined to the belt with rivets,
and 2 shews an empty socket.
Fig. 3. is an elevation a longitudinal section through in A shewing second
method form of fastening with said the hollow slotted or serrated socket, and
3 shews the hollow slotted or serrated socket after being driven home, and 3' the socket
before being driven.
Fig. 4. is an a perspective elevation of the said hollow socket shewing as employed
in the first method form of fastening.
Fig. 5 and 6 are perspective elevations of the said socket shewing as employed in
the second method of fastening.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
That these hollow tubes-take-all-strain-off-the-rivets & prevent the rivets from
springing or bending during the time of fastening.
also claim that these said hollow slotted sockets expand during the time
of insertion; and thereby make as firm and adhesive junction as can be procured.
1. Bell fasteners formed with hollow projections or sockets, through which the rivets
are passed, for the purpose and in manner substantially as herein shewn and described.
2. Belt fasteners formed with hollow projections or sockets which are slotted or serrated
at the ends thereof, for the purpose of rivetting the same, in manner substantially as
herein shewn and described.
