IMPROVED MACHINERY FOR FINISHING BOOT AND SHOE SOLES AND HEELS
Year: 1884

page_text: We JOHN KEATS of Frankfort-on-the-Main in the Empire of Germany and
OWEN ROBINSON of Champion Works, Kettering in the County of Northampton
do hereby declare the nature of our invention for IMPROVED MACHINERY FOR
FINISHING BOOT AND SHOE SOLES AND HEELS to be as follows:-
This invention relates firstly to a novel device for finishing the soles of Boots
and Shoes by what is known as the sand papering process, and secondly to a novel
form of Rasp for shaping up the heels of Boots and Shoes. These devices are
mounted upon the opposite ends of a horizontal shaft of a paring or finishing
machine, and receive their driving motion therefrom.
When sandpapering by hand, a circular motion is commonly given to the paper
in order to obtain a smooth surface on the flat. It is to obtain such a motion,
but of an improved character, that the device which we will now describe is
constructed.
Fitted to the end of a sleeve bearing, through which the tool shaft passes, is a
socketted piece which is intended to receive a wheel carrying an elastic tyre of
india rubber.
Made fast to the end of the tool shaft which projects into the socketted piece is
a cross head, which carries an adjustable excentric pin. This pin is intended to
carry the wheel with the elastic tyre, and hold it in frictional contact with the
inner periphery of the socket piece. In the centre of this wheel is fixed a sleeve,
and it is held in place on the pin by a screw that enters the end of the pin.
In front of this wheel is fitted a circular pad of india rubber, having a central
recess that will allow of its being forced onto the end of the sleeve and into
contact with the wheel. Over the face of this pad sand paper or equivalent
material is strained, the same being held in place by a binding ring or equivalent
means. If now rotary motion is imparted to the tool shaft, this shaft will,
through its cross-head and crank pin, carry round the wheel which is in contact
with the socket piece, and as the wheel is mounted excentrically thereof, it will,
while revolving over the inner periphery of the socket receive an axial motion.
As, however, the elastic pad, faced with sand paper is in frictional contact with the
wheel it will receive therefrom a compound revolving rotary motion; consequently
as the work is brought under the action of the covered pad, the finishing of the ⚫
sole will be effected in a rapid and most efficient manner.

page_text: The rasp takes a hollow convex shape and it is pierced at its centre to enable it
to be passed on to the tool axle. A shoulder is formed on the axle for it to abut
against, and it is held firmly in place by a clamping nut.
The profile of the rasp corresponds with the form intended to be given to the
heel, and the breadth of the acting surface of the rasp will be equal to the height
of heel intended to be brought to shape. A fixed guide will be required to protect
the upper from the action of the tool, and by entering the "crease" to retain the
Boot in the proper position while under the action of the tool.
As it is customary in the shoe trade to use an endless band of sand paper in
finishing the sole and heel we have provided the tool shaft with a pulley for the
reception of such a band, which being held at tension by an adjustable pulley, will
receive a travelling motion on the rotation of the shaft.

page_text: We JOHN KEATS of Frankfort on the Main in the Empire of Germany and OWEN
ROBINSON of Champion Works Kettering in the County of Northampton do hereby
declare the nature of our invention for "IMPROVED MACHINERY FOR FINISHING:
BOOT AND SHOE SOLES AND HEELS" 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 firstly to a novel device for finishing the soles of boots
and shoes by what is known as the sand papering process and secondly to a novel.
form of rasp for shaping up the heels of boots and shoes These devices we
propose to mount upon the opposite ends of a horizontal shaft of a paring or
finishing machine and to drive the same by belt or gearing from any motive power
source.
When sand papering by hand the soles of boots and shoes a circular motion is
commonly given to the paper in order to obtain a smooth surface on the flat. It is
to obtain such a motion but of an improved character that the device which we
will now describe is constructed.
In Sheet I of the accompanying Drawings Fig 1 is a side view partly in section:
of our improved sand papering device and Fig 2 is a front end view of the same
the sand papering pad being removed the better to exhibit the means for driving
the same.
A A is a forked bearing bolted to the side framing of a paring or finishing
machine and serving to carry one end of the shaft B to which the sand papering
device is connected. Bolted to the forked piece A and concentric with its bearings
is a socketted or cup piece C which is intended to receive a wheel D carrying an
elastic tyre of india rubber. Into the cup piece C projects the shaft B and made
fast to it is a grooved disc or cross-head B which carries an adjustable excentric
pin 6 This pin receives upon it the wheel D-This wheel is provided with an
extended bub and it is held in place upon the excentric pin by means of a screw b₁
which enters the end of the pin b and fits into an annular recess formed in the end
of the hub E is a pad of india rubber having a central recess that will allow of its
being forced onto the hub of the wheel D-Over the face of this pad sand paper
or equivalent material is strained the same being held in place by a binding ring
or equivalent means If now rotary motion is imparted to the shaft B this shatt
will through its cross head B¹ and crank pin b carry round the wheel D which is
in contact with the cup piece C and as this wheel is mounted excentrically thereof
it will while revolving over the inner periphery of the cup piece, receive an axial
motion. As however the elastic pad E faced with sand paper is in frictional
contact with the wheel D it will receive therefrom a compound revolving rotary
motion consequently as the work is brought under the action of the covered pad
the finishing of the boot sole will be effected in a rapid and most efficient manner.
As it is customary in the shoe trade to use an endless band of sand paper in
finishing the sole and heel we have provided the shaft B with a pulley as at F for
the reception of such a band which is passed over an adjustable pulley Ft carried
by the forked bracket piece A.
On this pulley being adjusted to hold the band at tension it will receive a
travelling motion by the rotation of the shaft B.
of
In sheet II of the accompanying Drawings we have shewn our novel construction
rasp Fig 3 being a side view partly in section of the rasp in position on its shaft
with the adjustable guide for the work also in position and Fig 4 is a front view of
the same.

page_text: G is the rasp which it will be seen is circular with a convex acting surface-It
is made of steel in one piece and hollow to facilitate its manufacture and it is
pierced at its centre to enable it to be passed onto the tool axle B which at this
end is carried in a bracket bearing A¹. A shoulder 62 is formed on the axle for it
to abut against, and it is held firmly in place by a clamping nut 63.
The profile of the rasp G must correspond with the form intended to be given to
the heel and the breadth of the acting surface of the rasp will be equal to the
height of heel intended to be brought to shape. H is a guide which protects the
upper from the action of the tool and by entering the " crease" retains the boot in
the proper position while under the action of the tool This guide is carried by a
horizontal slide H¹ bolted to the bracket piece. A¹ and adjustable horizontally
thereon. The guide is also capable of vertical adjustment on the slide-H¹ it being
secured thereto by a screw bolt working in a vertical slot.
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,

in contact with the fixed cup or socket and thereby imparting to the elastic pad a
compound,motion for finishing boot and shoe soles in the manner above described.
Secondly, The construction of rotary rasp as above described for, shaping, boot
