AN IMPROVEMENT IN AND APPARATUS FOR SELF FEEDING NAIL CUTTING MACHINES
Year: 1879

page_text: LETTERS PATENT to Luke Ellis and William West, both of Leeds, in the
County of York, Cut Nail Makers, for the Invention of "AN IMPROVEMENT
IN AND APPARATUS FOR SELF FEEDING NAIL CUTTING MACHINES."
PROVISIONAL SPECIFICATION left by the said Luke Ellis and William
West at the Office of the Commissioners of Patents on the 12th December
1879.
LUKE ELLIS and WILLIAM WEST, both of Leeds, in the County of York, Cut
Nail Makers. "AN IMPROVEMENT IN AND APPARATUS FOR SELF FEEDING NAIL
CUTTING MACHINES."
This machine operates by being connected to any nail cutting machine by any
suitable means.
The machine is so constructed as to receive the strips of iron to be cut into nails
between jaws, which are arranged to open and shut automatically so as to allow the
strips to move forward in the ordinary manner.
There is a hollow tube which works on bearings to which the jaws are fixed,
holding the strips which are operated upon by the cutters.
The tube, jaws, &c., are made to turn backwards and forward, and to draw back
by means of lever, camb, rack and pinion, as is required for nail cutting. The
jaws open to allow the strips to move forward to a gauge; the machine then cuts
off the nail.
By a mechanical arrangement the jaws close to prevent the strips from, pressing
against the cutters; they also draw back and turn the strip for another nail to
be cut.

the said Luke Ellis and William West in the Great Seal Patent Office on the
12th June 1880.
LUKE ELLIS and WILLIAM WEST, both of Leeds, in the County of York, Cut
Nail Makers. "AN IMPROVEMENT IN AND APPARATUS FOR SELF FEEDING NAII
CUTTING MACHINES."
The object of this Invention is the cutting up of strips of iron, &c., into nails by
a self-feeding feeding machine.
This machine operates by being connected to any nail-cutting machine by any
suitable means.
The machine is so constructed as to receive the strips of iron, &c., to be cut into
nails between jaws or pincers, which are arranged to open and shut automatically
so as to allow the strips of iron to move forward in the ordinary manner and at the
proper time.
There is a hollow tube which works on bearings secured to cast iron frame; on
the end is fixed the jaws or pincers for holding the strips of iron, &c., while being
operated upon by the cutters of the nail cutting machine.
The tube, jaws, &c., are caused to turn over backwards and forwards, and to
draw back by means of lever, rack, pinion, and cam, as is required for nail
cutting.
The jaws or pincers are caused to open to allow the strips to move forward to
gauge by being brought in contact with a ferrule working on stud fixed to anvil or
bearer.
As soon as tube, jaws, &c., move to turn over the end of the arm of the jaw is
liberated from the pressure on the ferrule, the spring then causes the jaw or pincer
to close to grip the strip of iron, to hold it from pressing forward against the
cutters of the cutting machine while it is being turned over ready for another nail
to be cut.
And in order that our said Invention may be fully understood, we will now
proceed to describe the annexed Drawings of the same.
Figure 1 is a side elevation.
Figure 2 is a plan.
Figure 3 is an end elevation.
The reference letters in one Figure correspond with those in the others.
a, cast iron frame.
b, cast iron stand.
c, weights for drawing the strips forward.
d, strap or cord for
ditto.
e, pulleys over which strap or cord wraps.
f, casting for bearing clam stick.
g, slide or bearer for regulating the feeder.
h, slide for ditto
ditto.
lever, on the end of which is secured rack.
j, pinion keyed on tube for working or oscillating the tube.
k, hollow into which the strips to be cut are put.
Z, cam with two flat sides and half round end.
m, anvil or bearer on which the cam works.
n, jaws or pincers for holding strips of iron.
o, side pieces for securing and regulating the jaws.
p, ferrule or runner to open jaws.
q, small wheel on screw for moving slide.
r, bearings for tube to work in or on.
8, support for bearing.
t, clam stick for holding strips of iron, &c.

page_text: u, cross head fixed on clam stick to which is attached the straps or cords.
v, w, stops to stop the tube from turning too far.
x, bracket to attach selfeeder to nail machine.
y, spring to hold tube on anvil or bearer.
z, springs for closing jaws or pincers.
a 1, connecting rod to receive motion from nail cutting machine.
Having thus described the nature and object of our said Invention, we would
observe in conclusion that we do not confine or restrict ourselves to the precise
details herein given, as they may be modified to suit certain circumstances without
departing from the nature of our said Invention; but that we claim as new and
novel, and desire to be secured to us by the hereinbefore in part recited Letters
Patent is,--
First. The self acting jaws or pincers.
Second. Springs for closing jawa
Third. The ferrule or runner for opening jaws.
Fourth. The side pieces for regulating jaws.
Fifth. The arrangement for bearing the rack.
Sixth. The slides for regulating the feeder.
In witness whereof, we, the said Luke Ellis and William West, have hereunto
set our hands and seals, this Eleventh day of June, in the year of our Lord
One thousand eight hundred and eighty.
