Improvements in and connected with the Manufacture of Cast Hob
Nails, Boot Protectors, and kindred articles having One or More
Shanks or Prongs.
I, FREDERICK THEOPHILUS GILES, of 152, Coronation Road, in the City and
County of Bristol, Nail Manufacturer, do hereby declare the nature of this
invention to be as follows:-
My invention relates to the manufacture of cast hob nails, boot protectors and
kindred articles having one or more shanks or prongs and used on boots, shoes, and
other articles, the object being to provide the shanks or prongs of such nails, boot
protectors and other articles when cast in malleable iron or other metal with screw
threads or other projections which will prevent such nails, boot protectors and
other articles from falling out of the soles and heels of boots, shoes and the like
when the leather etc. dries (or from other causes) as is frequently the case with
ordinary cast hob nails and the like. It will be understood that cast nails and the
like for purposes other than use on boots and the like can be manufactured
according to this invention.
In carrying out my invention I advantageously make use of the nail moulding
machinery forming the subject of former Letters Patent Nos. 4774 and 6586 both
of 1884 by combining with the shank or prong moulding portions of such
machinery a motion which will cause the shank or prong patterns to revolve whilst
being put into position for and making the moulds, also whilst being withdrawn
from such moulds when made.
A similar motion is to be applied to what are known in the trade as "False-
heads " or Hand Pricking Machines" for pricking one or more sprays at one
time.

Nails, Boot Protectors, and kindred articles having One or More

I, FREDERICK THEOPHILUS GILES, of 152, Coronation Road, in the City and
County of Bristol, Nail Manufacturer, do hereby declare the nature of this

page_text: invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
1
My invention relates to the manufacture of cast hob nails, shoe rivets, shoe
bills, boot protectors, and kindred articles having one or more shanks or prongs
and used on boots, shoes, and other articles, and also of screws and bolts with or
without heads, the object being to provide the shanks or prongs of such nails, boot
protectors and other articles, when cast in malleable iron or other metal, with
screw threads or like projections which will prevent such nails, boot protectors and
other articles from failing out of the soles and heels of boots, shoes and the like
when the leather etc. dries (or from other causes) as is frequently the case with
ordinary cast hob nails and the like. It will be understood that cast nails and the
like for purposes other than use on boots and the like can be manufactured
according to this invention.
In carrying out my invention I advantageously make use of nail moulding
machinery of the kind forming the subject of former Letters Patent Nos. 4774 and
6586 both of 1884 by combining with the shank or prong moulding portions of such
machinery a motion which will cause the shank or prong patterns to revolve whilst
being put into position for and making the moulds, also whilst being withdrawn
from such moulds when made.
To enable the invention to be fully understood I will describe it by reference to
the accompanying drawing which is a vertical section of moulding machinery.
adapted for making screwed shanks, it being understood that I make no claim in
this application to apparatus for producing cast hob nails, etc., and that I do not
confine myself to articles made by the apparatus herein described and shown.
a is the frame of the machine, 6 is the moulding plate thereof, c, care the
screw-threaded pattern stems or prickers which are designed to be projected
through the moulding plate & and to be withdrawn therefrom and to have imparted
to them simultaneously with the linear motion a rotary motion, as above men-
tioned, for forming moulds adapted to produce screw-threaded shanks.
the
To obtain the simultaneous linear and rotary motions I advantageously form the
lower portions of the pattern-stems with screw-threads which are made to
engage with screw-threaded holes in a fixed plate d and I provide each of the
stems with a toothed wheel so arranged that the adjacent toothed wheels engage
with one another. To simultaneously actuate all the toothed wheels 'I provide a
spindle e the upper part of which is formed with a screw-thread e¹ of the same
pitch as that upon the lower ends of the pattern stems c, the screw-threaded end e
also engaging with an internally screw-threaded hole in the fixed plate d and
being provided with a toothed wheel e which engages with the toothed wheels c²
upon the adjacent pattern stems. The lower part of the spindle e has upon it a
bevel wheel f which is arranged to rotate in a plate g secured to
frame a of the machine. The bevel wheel f is adapted to be actuated by a second
bevel wheel h mounted upon a spindle h¹ through the medium of a hand-wheel h³
and is connected to the spindle e by means of a sliding key and elongated key way.
With this arrangement when the spindle e is rotated from the hand-wheel h³, as,
above mentioned, it moves axially on account of 'the engagement of its screw-
threaded end e¹ with the plate d, the axial movement being rendered possible by
the sliding key and elongated key-way in the lower part of the said spindle; the
rotation of the spindle e turns the toothed wheels ² and thereby the pattern
stems c which are also moved axially by reason of the engagement of their screw-
threaded lower ends with the fixed plate d. As the screw-threads upon the pattern-
stems c and the spindle e are of the same pitch the axial movements imparted to
the said pattern-stems c and to the spindle e are equal, so that the toothed wheels
are aways in engagement with one another.
A similar motion is to be applied to what are known in the trade as "False-
heads" or Hand Pricking Machines" for pricking one or more sprays at one
time.

page_text: 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: -
Hob nails, shoe rivets, shoe bills, headed screws and bolts having nicks or recesses
in their heads, screws and bolts without heads, boot protectors and kindred articles
having one or more screw-threaded shanks or prongs and cast, substantially as
herein before described.
