IMPROVEMENTS IN THE MANUFACTURE OF BOOTS AND SHOES FOR CRICKETING AND OTHER USES AND IN THE MEANS FOR CARRYING OUT SUCH MANUFACTURE
Year: 1884

page_text: I, ALFRED VINCENT NEWTON of the Office for Patents 66 Chancery Lane in the
County of Middlesex, Mechanical Draughtsman, do hereby declare the nature of
the invention for IMPROVEMENTS IN THE MANUFACTURE OF BOOTS AND SHOES
FOR CRICKETING AND OTHER USES AND IN THE MEANS FOR CARRYING OUT SUCH
MANUFACTURE, to be as follows:-
This invention relates to the application of moulded india rubber soles to boots
and shoes such soles being employed as is well known for giving a firm foot-hold
upon grass and sward. These soles have been attached to leather soles by cement
which is liable to give way, and they have been further secured by stitching; but to
provide a surface for the stitching a smooth margin was made at the edge of the sole
the corrugations or roughened parts being consequently confined within the margin.
It has been proved, however, that soles of this character are very defective owing
to the absence of the corrugations from the edge.
Now the object of the present invention is to retain the advantage of the
corrugations or roughenings extending over the whole breadth of the sole and at
the same time to provide for the securing of the sole in place by even stitching,
such stitching being protected from wear by the corrugations or other projections
moulded on the india rubber sole.
In moulding the sole a groove or channel is formed extending all around it,
within say a quarter-of-an-inch of the edge to receive the stitches; and to enable
the sole to be sewn with regularity and precision a new form of pressing and
feeding foot is provided for the sewing machine used, which will be of the kind
that has a shuttle above the work. This pressing and feeding foot will bear upon
the top of the corrugations and to enable it to act as a gauge to the work and
thereby to ensure an even line of stitching, the feeding foot has formed on its
Peter 42

page_text: under face, towards the rear, a flat vertical projection which enters into the groove
or channel in the sole and acts as a gauge for maintaining the proper position of the
work with respect to the needle during the feeding operation.
Before stitching, it may be convenient to cement the india rubber sole to the
leather sole and when this compound sole is made fast to the inner sole it may be
stitched to the welt in the usual manner.
The shuttle thread may be passed through a solution of india rubber to protect
it from the effects of moisture, the needle thread being a waxed thread, and
appearing in the welt channel as usual.

page_text: I, ALFRED VINCENT NEWTON of the Office for Patents, 66 Chancery Lane in the
County of Middlesex, Mechanical Draughtsman, do hereby declare the nature of
my invention for IMPROVEMENTS IN THE MANUFACTURE OF BOOTS AND SHOES
FOR CRICKETING AND OTHER USES AND IN THE MEANS FOR CARRYING OUT SUCH
MANUFACTURE, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention (communicated to me from abroad) relates to the application of
moulded india rubber soles to Boots and Shoes, such soles being employed, as is
well known, for giving a firm foothold upon grass and sward. These soles have
been attached to leather soles by cement which is liable to give way, and they have.
been further secured by stitching, but to provide a surface for the stitching a smooth
margin was made at the edge of the sole, the corrugations or roughened parts being
consequently confined within the margin. It has been proved however that soles
of this character are very defective owing to the absence, from the edge of the
corrugations.
Now the object of the present invention is to retain the advantage of the
corrugations or roughenings extending over the whole breadth of the sole, and at
the same time to provide for the securing of the sole in place by even stitching
such stitching being protected from wear by the corrugations or other projections
moulded on the india rubber sole.
and
In the accompanying drawing,
Fig: 1 shews in side elevation a Shoe constructed according to this invention,
Fig: 2 is a plan of the improved sole.
Figs 3 4 and 5 are transverse sections of the india rubber sole taken respectively
in the lines 1, 2; 3, 4 and 5, 6 of Fig 2.
Fig 6 is a transverse section of a welt shoe shewing the mode of assembling the
parts and connecting them together by external stitching.
Fig 7 is a similar view of a shoe formed without a welt and having the soles
attached by internal stitching.
Figs: 8 shew in several views the form of presser and feeding foot employed in
sewing the improved sole by machinery.
In moulding the sole a groove or channel is formed extending all around it from
toe to heel within, say, a quarter of an inch of the edge, and cutting across the
ribs or corrugations where they occur. These ribs or corrugations are arranged
transversely of the sole and extend from edge to edge thereof as shewn at Fig: 2.
At the waist these corrugations cease, to be renewed again at the heel but the
edges of the waist are made sufficiently thick to allow of the channel being formed
therein as shewn at Fig: 4.
a a is the groove or channel made to receive the stitches and cutting through
the transverse ribs or corrugations. Externally of this groove at the toe and heel
the roughened parts are arranged radially the better to provide against slipping.
It is for the purpose of sewing on the channelled sole with regularity and precision
that the new form of pressing and feeding foot shewn at Figs 8 is provided for the
sewing machine used, which machine will be of the kind that has a shuttle above
the work. This pressing and feeding foot is slotted as usual to allow of the needle
passing through it, and the flat portion of its under surface bears upon the top of
the ribs or corrugations. To enable it to act as a gauge to the work and thereby
to ensure an even line of stitching, the feeding foot has formed on its under face

page_text: towards the rear a vertical projection b which enters into the groove or channel a
in the moulded india rubber sole and acts as a gauge for maintaining the proper
position of the work with respect to the needle during the feeding operation. To
give the presser foot a hold upon the work the vertical projection b is formed with
a chisel edge as at 6* which as the presser foot is advanced will take a firm hold of
the india rubber sole at the bottom of the groove, or if preferred, the under surface
of the presser foot, or that part which bears on the ribs or corrugations may be
roughened as usual, to take a bite of the sole.
By reference to Fig 6 it will be seen that the india rubber sole marked A covers
the ordinary sole of leather B and that the two soles are secured by stitching to the
welt C, the stitches lying in the groove formed in the moulded rubber. Before
stitching it may be convenient to cement the india sole to the leather sole and' to
attach this compound sole by "tingles" to the inner sole D. When thus secured
the compound sole may be stitched to the welt in the usual manner, the presser
.foot (Figs 8) serving to feed the work forward under the operation of the sewing
machine needle. The shuttle thread used may conveniently be passed through a
solution of india rubber to protect it from the effect of moisture, the needle thread
being a waxed thread and appearing in the welt channel as usual.
When applying the compound sole to shoes without welts it will be sewn directly
to the insole, the class of machine known as the "Horn" sewing machine being
used for the purpose. When internal sewing is employed as illustrated at Fig: 7.
the moulded rubber sole A may overlap the edges of the sole B, and thus give an
increased security against the access of moisture to the insole. "
Having now particularly described and ascertained the nature of the said
invention, as communicated to me from abroad, and explained in what manner
the same is to be performed, I declare that what I claim is
1. The employment in the manufacture of, Boots and Shoes, of soles composed of
india rubber or equivalent material having a surface roughened from edge to edge
and moulded with a groove or channel for receiving a line of stitches such groove
or channel traversing the roughened surface of the sole in the manner and for the
purpose above set forth.
2. For the manufacture of Boots and Shoes having grooved or channelled moulded
elastic soles, the construction and use of a presser and feeding foot as illustrated at
Figs 8 of the drawing.
