PROVISIONAL SPECIFICATION.
Improvements in the Construction of Apparatus for Cutting and
Punching Straps.
We JOSEPH BRINDLE of 14 Field Street Failsworth in the County of Lancaster
Mechanic, RICHARD LOVETT READE of New Hall Wythenshaw Road Sale, and JOHN
TAYLOR of 181 Northenden Road Sale, both in the County of Chester Merchants, do
hereby declare the nature of this invention to be as follows:--
This invention relates to improvements in the construction of the apparatus employed
for cutting the ends of driving straps to a bevil edge for the purpose of making a
splice joint and also to an improvement or addition to such apparatus whereby the
same machine may be employed for punching the holes therein for the insertion of the
"lacing employed for making such joint.
כן
In the first place we employ a clamp for holding the leather strap fast down onto
the movable table just beyond the point where the cut is commenced so that the strap,
the clamp, and the table all move together.
Secondly we employ an india rubber roller to keep down the thin end of the strap
so as to hold it flat down, whilst it is being cut to a knifo edge, and allow for any
inequalities of thickness that may occur.
By the use of these improvements the cut is always commenced at the proper
distance from the end and the knife edge is not left ragged as frequently occurs in the
ordinary machine when there are inequalities in the thickness of the strap.
When the ends have been bevilled it is usual to place over the same a metal plate
perforated with holes and to mark the position of the same on the strap by means of a
pencil or other marker and then to punch the lace holes therein by hand.
According to our invention we fit the machine with a row of punches which will be
brought down simultaneously by an excentric shaft so as to punch the first row of
holes whilst the strap is held by clamps.
The table is moved along by means of a weighted cord and is furnished with a
toothed rack at each side, and catches are provided for holding the same.
catches are lifted by tappets upon a shaft which is turned by hand so that upon
These
moving the table the distance of (say) one tooth the strap is moved into the right
position for punching the next row of holes, and so on; whereby the holes are
punched much more expeditiously and accurately than could be done by hand and the
acing of the joint is considerably facilitated.

Improvements in the Construction of Apparatus for Outting and
Punching Straps.
We JOSEPH BRINDLE of 14 Field Street Failsworth in the County of Lancaster
Mechanic, RICHARD LOVETT READE of New Hall, Wythenshaw Road Sale and JOHN
TAYLOR of 181 Northenden Road Sale both in the County of Chester Merchants, 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 :-
This invention relates to improvements in the construction of the apparatus employed
for cutting the ends of driving straps to a bevil edge for the purpose of making a
splice joint, and also to an improvement or addition to such apparatus whereby the
[Price 6d.]

page_text: same machine may be employed for punching the holes therein for the insertion of the
"lacing" employed for making such joint.
Our invention will be readily understood on reference to the annexed sheet of
drawings and the following explanation thereof.
Fig. 1 is a side elevation in section and Fig. 2 an end olevation in section of our
improved apparatus.
In the first place we employ a clamp a for holding the leather strap & fast down
onto the movable table c just beyond the point where the cut is commenced so that the
strap 6 the clamp a and the table call move together. Secondly we employ an india
rubber roller d to keep down the thin end of the strap so as to hold it flat down whilst
it is being cut to a knife edge and allow for any inequalities of thickness that may
occur.
e is the knife or cutter fixed to the frame f. is a shaft with one end g* squared
to receive a handle (not shewn) and by means of the gearing g', g³, driving the shaft g³
which moves the table e by the rack g³ and wheel g³. The upper surface of the table c
is inclined at the end ex to the angle of the bevil required.
By the use of these improvements the cut is always commenced at the proper
distance from the end, and the knife edge is not left ragged as frequently occurs in
the ordinary machine when there are inequalities in the thickness of the strap.
When the ends have been bevilled it is usual to place over the same a metal plate
perforated with holes and to mark the position of the same on the strap by means of
a pencil or other marker and then to punch the lace holes therein by hand.
According to our invention we fit the machine with a row of punches which
will be brought down simultaneously by an excentric shaft i, so as to punch the first
row of holes whilst the strap is held by a clump & fixed to the table c.
The end of the shaft i is preferably squared at ix so that the same handle which
works the table for cutting the strap may be used for punching the holes.
The table is moved along by means of a weighted cord and is furnished with a
toothed rack m, m' at each side, and catches n n are provided for holding the same.
These catches may be lifted by tappets upon a shaft which is turned by hand. We
prefer however to turn the shaft by hand and to thereby drive the toothed wheels o o¹
through the pinions p p and to provide these wheels o o' with excentrics or tappets
or crank pins o² o acting against the ends n³ n³ of these catches n n¹. These crank
pins oo³ are so set that when one catch is raised to release its rack the other is
in gear and the catches are so set see Fig. 1 that when one is raised the other allows
the rack and table to move a distance of half a tooth. Or two catches set as shown
may be used to each rack m and m¹.
And thus immediately a set of holes has been punched one of the catches is raised
and the weighted cord ? pulls the table c forwards for a distance of one half a tooth
and the strap is moved into the right position for punching the next row of holes and
so on whereby the holes are punched much more expeditiously and accurately than
could be done by hand and the lacing of the joint is considerably facilitated.
A hole may be made on each side of the frame into which a pin may be inserted
so as to hold the catches n and n' out of the teeth of their respective racks when
cutting or bevilling the ends of the strap.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The improved apparatus for bevilling and punching the ends of straps for the pur-
pose of making a splice joint substantially as herein before described and illustrated by
the drawings annexed.
