Improvements in Loose Nailing Machines for Coverings for the Feet.
I, EDWIN LEE, of 17, Church Bank, Bolton, in the County of Lancaster, Boot
and Clog Manufacturer, do hereby declare the nature of this invention to be as
follows:
This invention relates chiefly to improvements in that type of loose nailing
machines for coverings for the feet wherein the nails are fed from a nail box
down an inclined shoot or shoots communicating directly or indirectly with the
throat of the nailing machine, the object being firstly to provide means whereby
the nails are lifted from the said box to the level of the said shoot or shoots more
gently and regularly, secondly to effectively prevent the inlet of the said shoot
or shoots being obstructed by the nail in the hopper, thirdly to provide a new
form of jack for supporting clogs to be nailed, and lastly an improved form of
horn or work support drop, viz. connection between the jack or work support
lever and the respective cam on the driving shaft of the machine.
To this end and in lieu of employing a nail lifter which has a vertical rectili-
neal or a rotary movement, I employ a sector shaped or radial lifter suitably
fulcrumed to its nail box. The periphery of this sector or radial lifter is adapted
to move in contact with the interior of the nail box which obviously is shaped
conform therewith. The upper edge of the said sector shaped or radial lifter is
formed with a groove to receive the nails to be lifted to the level of the said shoot
and may be raised and lowered by means of an eccentric suitably rotated from
the driving shaft of the machine, say by chain gearing, and by an angular lever,
one arm of which engages a stud on the lower edge of the said sector shaped or
radial slide and the other arm, the arm of a strap around the said eccentric.
The nail shoot I cover with glass or other transparent material which prevents
the nails from jumping out and renders same visible in the shoot.
In connection with the nail box and nail shoot I employ a circular bush the
bristles of which project through into the nail box in line with the shoots and
prevent the shoot being obstructed by the nails in the box.
To facilitate the nailing of clogs I dispense with the ordinary horn support,
and pivot to the upper end of the horn shaft a pillar, slightly inclined and carry-
ing at its upper end crosswise a stud, formed with a guide adapted to bear against
the inner edge of the iron on the sole of the clog, whilst upon the straight part
of the said pillar I employ an adjustable collar having a vertical arm carrying
at its upper end a roller against which the sole of the clog bears when passing
from the sole iron to the heel iron.
My improved horn or work support drop consists of an upper and a lower rod
the upper one being vertically guided and adapted to be raised and lowered by a
cam on the driving shaft of the nailing machine and the lower one being jointed
to the back end of the horn or work support lever.
The inner ends of the said rods pass each other and the adjacent sides are
formed with teeth or serrations and are adapted to move in a box secured to the
frame of the machine. The outside of the lower end of the upper rod is formed
with an incline adapted to rise against an anti-friction bowl employed inside the
said box or against an incline therein, and thus bring the serrated or toothed

page_text: rod ends into gear with each other when the said rods are timed to lift and depress
the horn or work support whilst otherwise they remain disengaged.

Improvements in Loose Nailing Machines for Coverings for the Feet.
I, EDWIN LEE, of 17, Church Bank, Bolton, in the County of Lancaster, Boot
and Clog Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
This invention relates chiefly to improvements in that type of loose nailing
machines for coverings for the feet wherein the nails are fed from a nail box
down an inclined shoot or shoots communicating directly or indirectly with the
throat of the nailing machine, the object being, firstly, to provide means whereby
the nails are lifted from the said box to the level of the said shoot or shoots more
gently and regularly, secondly, to effectively prevent the inlet of the said shoot
or shoots being obstructed by the nail in the hopper, thirdly, to provide a new
form of jack for supporting clogs to be nailed, and, lastly, an improved form of
horn or work support drop, viz. connection between the jack or work support
lever and the respective cam on the driving shaft of the machine.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures, Fig. 1 being a front view of my
improved nail lifting device and horn or work support, Fig. 1 a sectional front,
view and Fig. 2 a plan, and Fig. 3 sectional end view of the nail lifting device
only, Fig. 4 is a side elevation of a complete nailing machine showing my improve-
ments attached, and Fig. 5 a sectional back view showing my improved horn or
work support drop.
In carrying out my invention and referring to the figures generally, in lieu of
employing a nail lifter which has a vertical rectilineal or a rotary movement, I
employ a sector shaped or radial lifter or lifters a, see more particularly Figs. 1*
& 3, in the present instance two, suitably fulcrumed to the nail box b. The peri-
phery of each of these sectors or radial lifters a is adapted to move in contact
with the interior of the nail box which obviously is shaped conform therewith.
The upper edge of each of the sector shaped or radial lifters a is formed with
a groove c to receive the nails to be lifted to the level of the shoot d which con-
veys the nails to the throat e of the machine and may be raised and lowered by
means of an eccentric (not shown) suitably rotated from the driving shaft of the
machine, say by chain gearing, and by an angular lever (not shown) one arm of
which engages a stud on the lower edge of the said sector shaped or radial slide
and the other, the arm of a strap around the said eccentric; or as shown in the
drawing, Figs. 1 & 2, by spur wheels f & g, the former being secured upon the
driving shaft h and the latter furnished with an adjustable crank pin i, which by
means of a rod is linked to a lever suspended from the nail box 6 and engages
the lower end of the nail slide a by means of the stud m.
The nail shoot I cover with glass or other transparent material n which
prevents the nails from jumping out and renders same visible in the shoot d.
In connection with the nail box and shoot d, I employ a circular brush o, sec
Figs. 1, 1 & 2, the bristles of which project through into the nail box in line
with and prevent the shoot d being obstructed by the nails in the box b.
In the present instance the brush o is secured upon a shaft p mounted in bear-

page_text: ings secured to the inner side of the nail box band rotated from the driving
shaft by means of a cord q, cord pulleys r & s and spur wheels f, g, & t.
To facilitate the nailing of clogs I dispense with the ordinary horn support,
and pivot to the upper end of the horn shaft u a pillar v, see Figs. 1 & 4, slightly
inclined at its upper end and carrying crosswise a stud forming a guide adapted
to bear against the inner edge of the sole iron t' of the clog, whilst upon the
straight part of the pillar I employ an adjustable collar w having a vertical
arm w carrying at its upper end a roller w2 which is set up against the sole of
the clog when passing from the sole iron to the heel iron."
Referring to Figs. 4 & 5 my improved horn or work support drop consists of an
upper and a lower roda, the upper one being vertically guided in a box a²
secured to the frame of the machine and adapted to be raised and lowered by the
cam h' on the driving shaft h and the lower one at being jointed to the back end
of the horn or work support lever u¹, see Fig. 4. The inner or adjoining ends of
the said rods pass each other in the box a², see more particularly Fig. 5, and the
adjacent sides thereof are formed with teeth or serrations ³. The outside of the
upper rod is formed with an incline y which, when the rod x is lifted by the
cam h and lever he passes against an anti-friction bowl y' (or against an incline)
and then presses the toothed or serrated end of the upper rod x into gear with
that of the lower rod a¹, as shown in the drawing, so as to cause the lower rod ³,
to be lifted by the upper rod r and the horn or work support to be depressed
during the feeding of work.
As the lever w¹ takes up a position of rest, the recess y² formed at the end of
the incline y in the rod comes opposite the bowl y and permits the spring z to
pull the toothed or, serrated end of the upper rod out of gear with that of the
lower rod 1.
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:-
1st. In loose nailing machines of the type hereinbefore specified, in combi-
nation with the upper end of one or more nail shoots d, one or more radial or
sector like nail lifters a, each fulcrumed to and adapted to rise and fall in a nail
box of corresponding shape, all substantially as set forth.
2nd. In a loose nailing machine of the type hereinbefore specified, in combi-
nation with a nail box or, boxes each containing a nail lifter and with a shoot
or shoots communicating therewith, a circular brush o projecting inside the said
nail box and adapted to rotate in contact with the said shoot or shoots and thereby
prevent the inlet of the said shoot or shoots from becoming obstructed by the
nails in the box, all substantially as set forth.
3rd. In a loose nailing machine for clogs, a horn or work support hinged to
the horn or work support shaft u and having at its upper end a guide adapted
to bear against the inner side of the sole iron t' on the clog and below the same a
vertically adjustable roller w2 which supports the clog when the sole iron leaves
the said guide, all substantially as set forth.
4th. In a loose nailing machine, a two part connection & ¹ between the horn
or work support lever and cam lever h², the adjacent ends of which are formed
with teeth or serrations, the upper part in its lowest or position of rest, being
out of gear and when raised, pressed into gear with the lower part by a bowl y¹
or the like, all substantially as set forth.
