IMPROVED MACHINERY FOR SPOOLING WIRE
Year: 1879

page_text: LETTERS PATENT to Donald Josiah Kempson, of the Firm of T. and L. Jenkins,
Wire Manufacturers, and Alfred Fletcher, Machine Maker, both of Birmingham,
in the County of Warwick, for the Invention of "IMPROVED MACHINERY FOR
SPOOLING WIRE."
Sealed the 25th November 1879, and dated the 28th May 1879.
PROVISIONAL SPECIFICATION left by the said Donald Josiah Kempson and
Alfred Fletcher at the Office of the Commissioners of Patents on the 28th May
1879.
DONALD JOSIAH KEMPSON, of the Firm of T. & L. Jenkins, Wire Manufacturers,
and ALFRED FLETCHER, Machine Maker, both of Birmingham, in the County of
Warwick. "IMPROVED MACHINERY FOR SPOOLING WIRE."
The wire used for reaping machines has hitherto generally been wound on to
spools in a lathe, the wire being guided by hand, which is attended with danger to
the attendants, and it cannot be wound upon the spools evenly.
By our Invention we accomplish the same object by machinery in a better manner,
(i.e.) the wire is wound on the spools more evenly and with little or no danger to
the attendants, and we accomplish the work more rapidly.
Our improved machinery resembles in some respects a lathe with the head stock
and back poppet, between which the spool is placed on a mandril. The spindle of
the head-stock carries a fine worm gearing into a corresponding wheel hung on a
shaft at right angles to the axis of the spool and poppets; this shaft also carries an
oval toothed wheel gearing into another wheel similar in shape to the figure 8.
This figure 8 wheel carries a crank pin, which may be adjusted to any desired throw,
working in a vertical slot formed in a saddle sliding upon two horizontal rods or
other slides carried by arms on the frame of the machine. The saddle is supplied
with suitable guides or clips for guiding the wire on to the spools, and is made to
reciprocate by the eccentric wheels at a quicker speed when opposite each end than
when at the centre of its travel, thus effecting the desired object of winding the wire
evenly on the spools.
Sometimes we should use a connecting rod instead of the vertical slot, and an
eccentric instead of the toothed wheel, for the purpose of imparting the varying
motion to the saddle.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Donald Josiah Kempson and Alfred Fletcher in the Great Seal Patent
Office on the 27th November 1879.
DONALD JOSIAH KEMPSON, of the Firm of T. and L. Jenkins, Wire Manufacturers,
and ALFRED FLETCHER, Machine Maker, both of Birmingham, in the County of
Warwick, "IMPROVED MACHINERY FOR SPOOLING WIRE."
The wire used for reaping machines has hitherto been wound on spools by hand,

page_text: which is attended with considerable danger to the attendants, and they cannot be
wound evenly.
By our Invention we accomplish the same object by self acting machinery in a
better manner, by winding the wire on the spools more evenly, and with little or
no danger to the attendant, and the work is done more rapidly.
Our improved machinery resembles in some respects a lathe with the head stock
and back poppet, between which the spool is placed. One modification of our
machine is shown by Figure 1, side elevation; Figure 2, plan; Figure 3, end
elevation; and Figure 4, back elevation.
A is the spool placed upon the mandril in its proper position. B is the worm upon
the spindle of the head stock gearing into the fine toothed wheel C, which is hung
upon the shaft D at right angles to the axis of the spool and poppet spindle E. The
shaft D also carries at its back end the oval or other shaped wheel of which gears
into the wheel g, which is similar in shape to the figure 8. The wheel g carries
the crank pin h which is adjustable in the slot i to any desired throw, and which
works in the vertical slot j in the saddle K.; this saddle K slides freely backwards
and forwards on the two guide rods L and M which are carried by the head stock
The arm N of the saddle K is
and poppet, or in any other convenient manner.
supplied with a slot or other suitable means for guiding the wire on to the spool,
and is reciprocated by the eccentric wheels fand g so as to guide the wire on to the
spools, so as to produco a straight wound spool, a convex wound spool, or a concave
wound spool, which we easily effect by varying the shapes of the eccentric wheels;
but we should generally use wheels which would produce an even speed of travel,
and therefore a straight spool.
We can effect the same object by the modification shown at Figure 5, where O is
an eccentric and P a connecting rod working in the guides q, q, which would also
reciprocate the saddle so as to wind the spools in any desired manner.
We also attain the same end by the use of the screw R and the moveable nut S,
which is brought into action alternately on opposite sides of the screw R by the
weighted lever T working on the inclined plains U and V.
Having now described the nature of our Invention, and the manner in which
the same is to be performed, we wish it to be clearly understood that we do not
confine ourselves to the precise details herein shown and described, but we do claim
winding wire on spools by self acting machinery, as shown in the accompanying
Sheet of Drawings and modifications of the same.
In witness whereof, I, the said Donald Josiah Kempson, have hereunto set my
hand and seal, this Twenty-fourth day of November, in the year of our Lord
One thousand eight hundred and seventy ninc.
