COMPLETE SPECIFICATION filed by the said William Robert Lake at the
Office of the Commissioners of Patents on the 5th April 1880.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN MACHINERY FOR DRAWING
WIRE." A communication from abroad by Charles Dake Rogers, of Providence,
Rhode Island, United States of America.
This Invention relates to wire-drawing machines wherein a revolving drum is
employed upon which the wire is coiled as it leaves the draw-plate, and my
improvements consist in combining with the winding drum of such a machine
suitable means for stripping the heavy coil from the winding-drum, and bringing
it to such a position that it can be conveniently handled for removal from the
machine.
In the accompanying Drawing,
Figure 1 is a plan or top view of a coiling drum with my improvements applied
to the same, and
Figure 2 is an elevation of the said coiling drum with a portion of the same
broken away to illustrate more clearly the arrangement of my improvements.
Like letters indicate the same parts in both Figures.
A represents a coiling drum of the usual form, and which is mounted upon the
driving shaft B, so as to rotate therewith. This drum is provided with vertical
slots a to receive and guide two or more arms C which are hinged to a collar D
secured to the shaft B, and the flange A¹ of the said drum is grooved as at a¹ to
receive the ends of the said arms, thereby allowing the coil of wire to rest upon
said flange, and above the plane of the ends of the arms.
Loosely mounted upon the shaft B and
which is slotted in spiral lines as at c.
spiral slots
whose faces act as cams upon
and raise them, as shown in dotted lines in
within the drum is a cylindrical disc
The hinged arms C pass through these
the arms when the disc E is rotated,
Figure 2. The rotation of the disc E

page_text: and consequent raising of the arms C is effected by turning a crank F, which is
mounted on the vertical wall of the drum, and is connected with the disc E by
means of jointed links f, f', as shown in Figure 1.
The operation of my improved device is as follows:-
A desirable amount of wire having passed through the draw-plate and been
coiled upon the drum A the ends of the wire are secured to the body of the
coil which rests upon the flange A' and above the outer ends of the arms C. The
crank F is then turned towards the centre of the drum, which causes a partial
rotation of the annular disc E, and consequently the arms C are made to ride up
the faces of the respective inclined planes e to the position indicated in dotted
lines in Figure 2. A further rotation of the annular disc E to a small extent
causes the slots e to leave or run clear of the arms C, when the latter will be
supported in their elevated position upon the upper edge of the disc E. It is
obvious that the coil, of wire will thus be stripped by the arms from the
winding-drum, and brought to a position where it can be easily handled for
removal.
After the coil of wire has been removed the crank F is returned to its original
position, causing the disc E to revolve in the opposite direction, and the arms C
to pass into the slots e and be lowered when the drum will be again ready to
receive wire from the draw-plate.
Although I have shown and described a crank and arm connected with the
disc E, for the purpose of partially rotating the said disc. I am aware that the
base of the disc may be provided with teeth, and that a pinion meshing with said
teeth may be secured to the crank-shaft for the purpose of moving the disc, and
thereby raising the arms. I am also aware that the disc may be dispensed with,
and a loosely mounted gear wheel having cams or inclined planes upon its surface
may be used in its place.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent and the manner of performing the same, I wish it under-
stood that I claim,—
First. In a wire-drawing machine the combination of the coiling drum two or
more arms projecting outwardly beyond the vertical wall of said drum, and suitablo
mechanism for raising and maintaining said arms in an elevated position, sub-
stantially as above set forth.
Second. In a wire-drawing machine the combination of the slotted coiling-drum,
the driving shaft for the same, two or more arms passing outwardly through said
drum, two or more cams loosely mounted on said shaft, or an annular disc loosely
mounted on said shaft, and provided with cams and suitable mechanism for
causing a partial rotation of said cams, substantially as above described.
Third. The combination of the slotted coiling drum the shaft B, the hinged arms,
the multiple cam disc, and the rotating mechanism F, f, f', substantially as above
set forth and for the purpose specified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Fifth day of April, in the year of our Lord One
thousand eight hundred and eighty.
