I WILLIAM RANDALL HARRIS of number 5 Sussex Street Lower Broughton,
Manchester in the County of Lancaster Machinist do hereby declare the nature of
this Invention to be as follows:-
My Invention relates to the fasteners adapted for use in attaching together the ends
of straps or belts employed in transmitting movements in and to machinery as is well
understood. In the year 1867 Letters Patent bearing date the sixteenth day of
March and numbered 760 were granted to me for a metal strap fastener having rows
of pins, teeth or spikes which were caused to penetrate the material of the two belt
ends to be connected and on the seventeenth day of December in the year
1885 I made application for Letters Patent for an improvement in such
strap fastener.
In the using of driving straps or belts it is necessary at times
to tighten them and to accomplish this tightening it is necessary to re-make a
joint in the belt. For this purpose the fastener as heretofore made has not been well
suited and the object of my present invention is to obtain a strap fastener which will
permit the strap to be readily tightened at the required times. I make the one side
of the fastener in accordance with either of my former inventions of 1867 or 1885 or
I otherwise adapt it to be securely attached to one end of the strap. The fastener is
formed with a slot or opening through which the other end of the strap is passed and
a cross bar which constitutes the outer boundary of such slot on one side is provided
with a tooth or finger or with two or more teeth or fingers which prevent the end of
the strap from yielding to the strain so as to be withdrawn from the slot when the
strap is at work. The teeth may enter holes previously formed in the strap end
or may be hammered or forced into the substance of the strap but in some cases the
fastener is by intention adapted for connection with a strap which has been previously
perforated to suit the finger or fingers or the tooth or teeth upon the said cross bar.
To tighten a belt which is provided with my improved fastener of the last named
form it is only necessary to disengage the end which passes through the slot and to
make a fresh hole or fresh holes removing part of the strap end when desirable, and
to recouple the parts.

page_text: Improvement in Strap Fasteners.
I WILLIAM RANDALL HARRIS of number 5 Sussex Street Lower Broughton
Manchester in the County of Lancaster machinist 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 and accompanying
drawings:-
My Invention relates to the fasteners adapted for use in attaching together the ends
of straps or belts employed in transmitting movements in and to machinery as is well
understood. In the year 1867 Letters Patent bearing date the 16th day of March
and numbered 760 were granted to me for a metal strap fastener having rows of pins
teeth or spikes which were caused to penetrate the material of the two belt ends to
be connected and on the seventeenth day of December in the year 1885 I made
application for Letters Patent for an improvement in such strap fastener. In the
using of driving straps or belts it is necessary at times to tighten them and to
accomplish this tightening it is necessary to re-make a joint in the belt. For this
purpose the fastener as heretofore made has not been well suited and the object of my
present invention is to obtain a strap fastener which will permit the strap to be readily
tightened at the required times. 1 make one side of the fastener in accordance with
either of my former inventions of 1867 or 1885 or 1 otherwise adapt it to be securely
attached to one end of the strap. The fastener is formed with a slot or opening
through which the other end of the strap is passed and a cross bar which constitutes
the outer boundary of such slot on one side is provided with a tooth or finger or with
two or more teeth or fingers which prevent the end of the strap from yielding to the
strain so as to be withdrawn from the slot when the strap is at work. The teeth may
enter holes previously formed in the strap or may be hammered or forced into the
substance of the strap but in some cases the fastener is by intention adapted for
connection with a strap which has been previously perforated to suit the finger or
fingers or the tooth or teeth upon the said cross bar.
y Invention will be best understood when described with reference to the
accompanying drawings in which Fig. 1 is a perspective view of the fastener. Fig. 2
represents a longitudinal section of a belt joint effected by the use of such fastener and
Fig. 3 is a view of such joint. In Fig. 1 the fastener is represented in such a position
as will fully exhibit the underside of the fastener. In the said Fig. a is the back
plate are the teeth or spikes and ec are the clamping fingers or parts the
corresponding parts being represented by the same letters in the drawings
attached to the specification of my former and hereinbefore mentioned invention
of the year 1885. In the back plate a is formed a slot or opening d and on
one side this slot is bounded by a cross bar e which is connected by the side bars ff
with the said back plate all these parts being preferably cast or formed in one piece.
Upon the said cross bar are cast or formed two fingers or tongues g g which are
inclined and otherwise adapted to engage with holes formed in one of the strap or belt

page_text: ends which are to be connected as clearly indicated in Fig. 2 wherein represents one
strap end and the other strap end. When forming the joint the fastener is first
secured to one of the strap ends which in the example is indicated by i. The fastener
is secured by driving the spikes & into the substance of the strap end and hammering
or pressing down the clamps e over the strap end as indicated in Fig. 2 and as fully
described and indicated in the said former specification of the year 1885. The other
strap end which has been previously perforated to suit the tongues g is then passed
through the slot and the said tongues are entered into the perforations the parts being
then in the position indicated in Figs. 2 and 3. The tongues or fingers will resist
the tendency of the strap end to be withdrawn from the slot by the strain to which it
is ordinarily subjected when it is in use. To tighten a belt which is provided with
such a fastener it is only necessary to disengage the end which passes through the
slot and to make fresh holes removing part of the strap end when desirable, and to
recouple the parts. I do not confine myself to the exact method as indicated of
attaching the fastener to the strap i as other methods for the purpose may be adopted
as hereinbefore mentioned. In cases wherein it is not considered to be desirable to
have to punch or perforate the strap to suit the tongues y I should make such tongues
in the form of sharp teeth so that they could he forced into the substance of the strap,
but I prefer the formation illustrated in the drawings.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is :-
:-
(1) The strap fastener formed substantially as set forth and indicated herein before
with reference to the accompanying drawings.
(2) A strap fastener formed with teeth or spikes to enter the end of one of the
straps to be connected and with clamps to fold down upon such end and with a slot to
receive the end of the other strap and a cross bar provided with a finger or tongue or
with fingers or tongues to enter holes in such strap substantially as set forth and
indicated.
(3) A strap fastener adapted to be clamped or firmly secured to one strap or belt
end by any suitable means and to buckle to the other strap or belt end substantially in
the manner indicated in the drawings.
(4) A strap fastener adapted to be clamped' or firmly secured to one strap or belt
end by any suitable means and formed with a slot to receive the other strap or belt
end and with a cross bar provided with a tooth or with two or more teeth to enter the
substance of the strap or belt substantially as set forth and indicated.
