ALFRED JULIUS BOULT, of 323 High Holborn in the County of Middlesex,
Engineer, "AN IMPROVED TOOL APPLICABLE FOR USE IN THE MANUFACTURE OF
BOOTS AND SHOES [a communication from Stephan Fojes, of Kula in the
kingdom of Hungary.]
"
This invention relates to a tool or instrument intended for cutting away or
trimming that part of the sole of a boot or shoe which comes in contact with the
upper leather in course of manufacture so that the superfluous parts of the sole
may, by means of the said tool or implement, be evenly cut away in one piece
without any risk of injuring the upper leather whilst when the ordinary trimming
knife is used, boots or shoes made of perfect materials and satisfactory in every
other way frequently are, by inexperienced or careless use of the said ordinary
tool, injured or cut in the upper leather so as to seriously reduce their value.or
render the same entirely worthless. By using the improved tool hereinafter
described this can not happen, for in whatever direction the instrument is turned
or pulled, no incision can possibly be made except in the sole edge.
The tool or implement consists of a handle or shank along which runs a groove
for receiving a blade; there are two upper holes for the pins of a blade-regulator
or guard which keep the latter in the proper position
A cover is provided in the two lower screw holes of which screws are inserted to
connect the above mentioned parts. The blade consists in a narrow strip of steel
and is made with a double edge in order that when the one edge becomes blunt,
it may be turned, and the other edge used. As the lower end of the blade is wider
than the upper part, the groove for the blade in the shank or bandle is made in such
a way as to necessitate the blade being inserted in the groove with the proper
edge only and this is done by holding the instrument in a perpendicular position
It is then
and the blade drops into the right place without any further trouble.
screwed down a screw being provided over the blade and fitted into an aperture
in the handle-head and another screw is screwed into its place on the lower part
of the handle which holds the blade firmly in the handle and covers also the hole

page_text: at the end of the handle. When the knife requires grinding it is only necessary
to remove the bottom screw and to loosen the set screw which holds the blade
tight and the blade then easily comes out of the handle. In replacing the blade
care must be taken that its lower end be brought to lie closely on the blade regulator
or guard and be then screwed down in position although even if the parts are
improperly fitted together no injury would arise except that the blade would
not cut.
Only a small part of the blade is sharpened and only when one portion is worn
down by repeated grinding will the small narrow remaining part be filed away
and ground into shape again like the other end, a fresh part being then sharpened,
and this proceeding is followed each time the sharp part of the blade is worn
down.
The head of this tool has a shape similar to that of a bootmakers burnishing
tool, and the blado is encased between the two parts of the head whercof one
carries the stirrup shaped guard.
The sharp part of the blade projects beyond the head and is so surrounded by
the guard that it cannot touch the upper leather.
