North Britain for an invention of "IMPROVEMENTS IN MACHINERY FOR MAKING
EYELETTED LUGGAGE OR ADDRESS LABELS"
(Void by reason of the Patentee having neglected to file a Specification in
pursuance of the conditions of the Letters Patent.)
PROVISIONAL SPECIFICATION left by the said Charles Keith at the Office
of the Commissioners of Patents on the 3rd May 1882.
CHARLES KEITH, of the Town and County of Inverness, North Britain,
"IMPROVEMENTS IN MACHINERY FOR MAKING EYELETTED LUGGAGE OR ADDRESS
LABELS,"
This Invention relates to improvements in machinery for making eyeletted
luggage or address labels, and has for its object to produce such labels by
machinery with rapidity and accuracy, the machinery being capable of adjustment
to produce labels of various sizes.
The present improvements refer more particularly to that portion of label
making machines illustrated on Sheet 3, of the drawings attached to the Complete
Specification filed in pursuance of Letters Patent granted to the said Charles Keith,
No: 4677, A.D. 1879, namely the folding dies or stamps, and by which improve-
ments, the paper where folded for the eyelet is stamped and folded in a different
manner, and by a simpler and more effective piece of mechanism.-The improved
folding apparatus differs from the former folding apparatus in that the bracket,
the plunger, and the whole of the finger or folder mechanism are dispensed with.
The improved mechanism is worked by a cam keyed to a shaft in which a hori-
zontal lever with a pin works. This lever is fixed at its back end, to a frame, and
at its front end is jointed to another lever, which sometimes stands at right angles
to it. This lever is widened out at the top end and is furnished with double jaws,
or cranks to which the ends of two stamping and folding die levers are attached,
they being again carried up in the middle by two double jointed fulcra on cranks
and pins.

page_text: The actuating power is derived from the cam, on the shaft, which at each
revolution lifts or depresses the two levers, herein before referred to, producing a
belt crank motion, which again from the peculiar form of the cam itself, and the
action of another cam, and lever, hereinafter described give all the necessary
movements to the stamping and folding dies.
From the sometimes vertical lever an ear shaped slotted cam projects, into the
slot of which the one end of a horizontal lever is fixed by a pin and roller to give
an easy sliding movement; the other end of this lever is attached to a bracket
fixed to the underside of the frame of the machine. This cam is so shaped in
its slot that when the levers are raised the vertical lever with its two hammer-
like dies are at certain points drawn forwards, or released as the levers are raised
or depressed by the driving cam's revolution. At the initial period of a revolution
of the driving cam, the dies are tilted up and drawn back to their furthest position
from the cresses, and as the revolution proceeds the cam being made slightly
eccentric raises the levers and depresses the hammer-like dies towards the cresses,
but simultaneously with the raising of the levers the ear shaped cam catches and
draws forward the sometimes vertical lever and its dies so that the hammers or
dies come down exactly into the cresses, the movement given to the dies being
thus both vertical and lateral, the vertical giving the stamping action, and the
lateral, ensuring the label being properly folded over before receiving the second
blow of the dies. The improvements contain two dies, and two cresses, the web
of paper being first operated upon by the first or leading die and cress of a Y shape,
which stamps and folds the corners of paper after which the web passes on to the
next die with a square face which stamps and folds over the top fold of the label
which receives the eyelet. The same movements as are transmitted from the cam,
and its levers serve for both sides, and they fall, advance give their blows and
retire simultaneously.
