Improvements in the Method of and Means for Moulding and Casting
Hob-nails, also applicable in Moulding and Casting Heel-plates
and other Boot Protectors.
I, GEORGE HENRY JONES, of the Firm of Jones and Faulkner, of No. 1, Grove
Street, Rotford, in the County of Nottingham, Boot and Shoe Manufacturer, 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 method of and means for moulding
and casting hob-nails, which improvements may also be adapted to moulding and
casting heel plates and other boot protectors.
Hitherto the moulds of malleable hob nails, heel plates, and other boot protectors,
have had to be formed or constructed in separate operations. For instance after
the heads or plates of the hob nails or other protectors have been moulded and
formed, the shanks (moulded separately) have had to be pricked in or attached by
hand to the heads or plates aforesaid to obtain the mould for casting a spray of
hobs or other protectors. This whilst occupying considerable time and involving
expense for labor still leaves the articles when produced imperfect in many respects.
It is impossible in the method heretofore employed and as above described to ensure
the shanks being central upon the heads of the hob nails, hence there is very great
difficulty in making use of them in any nailing machine, consequently the operation
of affixing hob nails or the like protectors to the boot has been costly and in most
cases imperfect.
Now in accordance with this my invention I overcome these defects and produce
a mould from which any convenient and desired number of hobs may be cast and
all of which shall be perfect in construction, the shanks of necessity being centrally
situated upon the heads, and the nail when produced being adapted for attachment
to the boot by a nailing machine or by hand as may be required. A greater number
than heretofore may be produced from one casting and the cost of production is
most materially reduced."
In carrying my invention into effect I construct the mould in the following
manner.
«
"
دو
Upon each side of a metal or other plate which may be of any convenient thickness
and size I form longitudinal ribs or gets" and I connect these ribs or gets'
by a transverse rib or ribs. Upon each side of the longitudinal ribs and connected
thereto I have moulds or models exactly representing one half of each nail and shank
desired to be produced.
The ribs or gets" and models of half nails and shanks are respectively exactly
opposite one another upon each side of the mould plate so that the moulding in the
sand of one box when placed upon the other will exactly correspond and give the
mould of a complete nail and shank.
In operation the box upon one side of the mould or plate aforesaid is first filled
with sand pressed tightly within same in the ordinary manner, and then the box.
upon the other side of the mould or plate is filled and pressed. The boxes are then

page_text: disconnected, the mould or plate removed, and again put together when a moulding
is obtained giving a perfectly shaped hob with shank accurately in the centre
thereof.
It will be obvious that moulds for heel plates and other forms of boot protectors
may be similarly constructed and used.
And in order that this my invention may be fully understood and readily carried
into effect I will describe same with reference to the accompanying drawings and
letters and figures of reference marked thereon, that is to say:
Fig. 1 is a plan of one side of the mould plate constructed in accordance with
this invention.
Fig. 2 is an edge view of the same.
Fig. 3 is a section through line A. B Fig. 1, and
Fig. 4 shews to an enlarged scale the hob nail as produced from the mould
illustrated in the previous figures.
Similar letters of reference indicate like parts throughout all the figures wherever
occurring.
a is the metal or other mould plate upon each side of which are formed the ribs b
connected together by means of the rib c. d dare the moulds or models of the half
nails and shanks connected to the ribs b by the necks e. d d d are the heads of the nails
and ddd the shanks of same. These latter may be screw-threaded, grooved, or
plain, as may be required.
In making these half moulds of the nails sufficient care must be observed to keep
the shanks exactly central to the heads, and care must also be taken that the ribs
and half nails upon one side of the plate shall be exactly opposite those upon the
other, so that when the plate is removed from the boxes after the sand has been
pressed in, the mould formed is that of a spray of perfectly shaped hobs.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
J. The improvements in the method of and means for moulding and casting
hob nails also applicable in moulding and casting heel plates and other boot pro-
tectors, substantially as herein set forth.
2. In moulding and casting hob nails, heel plates and other boot protectors,
the mould plate a constructed or formed with the ribs b and c upon each side
thereof and with the half moulds or models d d¹ of the heads and shanks of the
naile or other protectors connected to such ribs b upon each side of the plate a, sub-
stantially as and for the purposes herein before described and shewn.
