IMPROVEMENTS IN THE CUTTERS OF RIVETTING MACHINERY EMPLOYED IN THE MANUFACTURE OF BOOTS, MILL STRAPS, HARNESS, HOSE PIPES, AND SIMILAR ARTICLES.”
Year: 1877

page_text: LETTERS PATENT to Joseph Appleyard, of Bradford, in the County of York,
Mechanic, for the Invention of "IMPROVEMENTS IN THE CUTTERS OF RIVETTING
MACHINERY EMPLOYED IN THE MANUFACTURE OF BOOTS, MILL STRAPS,
HARNESS, HOSE PIPES, AND SIMILAR ARTICLES.”
"
PROVISIONAL SPECIFICATION left by the said Joseph Appleyard at the
Office of the Commissioners of Patents on the 26th April 1877.
JOSEPH APPLEYARD, of Bradford, in the County of York, Mechanic. IMPROVE-
MENTS IN THE CUTTERS OF RIVETTING MACHINERY EMPLOYED IN THE MANUFACTURE
OF BOOTS, MILL STRAPS, HARNESS, HOSE PIPES, AND SIMILAR ARTICLES."
Hitherto in machines for the above purpose the cutters for severing the wire to
form the rivets have been so shaped that at each action thereof as much wire has
been cut to waste as is required to form a rivet. To obviate this I employ cutters
shaped as in the accompanying sketch; wherein A and B are the cutters, the wire
passing down the groove a and being cut by the edge b, which severs the wire, as
shown at c, thereby avoiding waste and dispensing with the fan which has hitherto
been employed for removing the waste when the machine was working.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Joseph Appleyard in the Great Seal Patent Office on the 26th October
1877.
JOSEPH APPLEYARD, of Bradford, in the County of York, Mechanic. " IMPROVE-
MENTS IN THE CUTTERS OF RIVETTING MACHINERY EMPLOYED IN THE MANUFACTURE
OF BOOTS, MILL STRAPS, HARNESS, HOSE PIPES, AND SIMILAR ARTICLES."
Hitherto in machines for the above purposes the cutters for severing the wire
to form the rivets have been so shaped that at each action thereof a portion of wire
has been cut to waste. To obviate this waste of wire I employ cutters constructed

cutters, and C the wire, which passes down the groove D and is cut against the
edge E of the cutter B, being pressed against it by the part F of the cutter A, the
form of the cut being shewn at G in Fig. 6. After the cutting operation the upper
portion of the wire is carried back to its first position by the part H of the cutter A.
To prevent the rivet or wire being withdrawn from the leather in the upward
movement of the cutters, a groove or clearance M is formed in the under side of the
cutter B, see Fig. 7. By the use of cutters of this construction and shape waste of
wire is avoided, and also the fan is dispensed with which has hitherto been
employed for removing the waste pieces.
The form of feeding apparatus shewn in Fig. 1 is provided with an improved
operating mechanism. The disc I is milled or serrated closely round the periphery,
and is operated on and held by small friction rollers J placed in tapered grooves in
the castings K and L, a front view of one of which is shewn in Fig. 2.
Having thus described the nature of my Invention, and shewn by Drawings how
the same is to be performed, I would have it understood that I do not confine
myself to the exact and precise shape of cutters herein shewn and described, as the
same may be varied without departing from the main features thereof, but what I
claim is, the construction and use of "cutters" shaped substantially as and for the
purpose herein shewn and described.
In witness whereof, I, the said Joseph Appleyard, have hereunto set my hand
and seal, this Twenty-fourth day of October, in the year of our Lord One
thousand eight hundred and seventy-seven.
Witness,
FAIRFAX ODDY.
