PROVISIONAL SPECIFICATION.
Improvements in Wire, Rod, and Tube Drawing Machines.
I, FREDERIC SMITH, of Caledonia Works, Halifax, in the County of York,
Wire Manufacturer, do hereby declare the nature of this invention, which has been
communicated to be from abroad by Jacques Manne, of Anderlecht, near Brussels,
in the Kingdom of Belgium, Engineer, to be as follows:-
This invention relates to coutinuous wire, rod and tube drawing machines where
a rod or wire or tube or two or more rods or wires or tubes are drawn through a
series of dies simultaneously and the object of the invention is to facilitate the
operation of wrapping the rod or wire or tube (hereinafter designated the wire) on
to the successive drawing through rollers without removing the dies from their
positions in the machine.
.
To accomplish this object a collar is formed round each drawing through roller
at or about the centre and on this collar is fitted a grooved clip the free ends of
which are turned up to form snugs or ears through each of which is cut a slot ;
these slots may be at right angles to one another and through them is passed
a metal link or equivalent; in a hole at each end of the link is a stud upon which
is secured an eccentric; the eccentrics serving to clamp the clip on to the roller
and draw the wire into the machine in the following manner :-)
A projection on the first eccentric is moved by hand so as to bring the eccentric
portion against one ear of the clip and cause it to grip the rotating roller slightly
but not sufficiently to set the clip in motion; to the eccentric at the other end of
the link is secured at or about mid-length a bar with a hook at each end, if two
series of discs are employed in the machine.
To grasp the end of the wire which has been previously pointed and passed
through the first die a clamp is employed into which the end of the wire is placed
and gripped. When the clamp is hooked on to one end of the hooked bar which
is in line with one series of the discs the second eccentric to which it is secured
turns upon its stud and brings its eccentric portion against the second ear of the
clip. This is sufficient to set the clip in motion and the resistance it meets with
in drawing the wire draws the hooked bar into a longitudinal position and still
further puts on the second eccentric causing the clip to close firmly upon the
drawing through roller and rotate positively with it thus drawing the wire
forward and wrapping it on to the roller for the desired number of times.
A bar is then laid across the frame and pushed toward the clip and as soon as
the projection on the first eccentric meets the bar it is knocked back and thereby
releases the clip. The rotation of the drawing through roller is then stopped and
the wire is released ready for having its end reduced to be passed through the
second die and into the clamp on the clip on the second drawing through roller
and so on until the wire finally reaches the winding on drum and the operation of
continuous drawing proceeds.
A second wire can be introduced into the machine by the use of the same series
of clips without interfering with the action of the machine and for this purpose the
second hooks on the bars are employed.
If it be desired to draw more than two wires simultaneously through the machine
the hooked bars would be extended to come in line with all the series of dies;
also two or more clips could be fitted upon each drawing through roller it
desired.

page_text: In place of the collar on the drawing through roller and corresponding annular
groove in the clip the groove might be in the roller and the collar in the clip.

Improvements in Wire, Rod, and Tube Drawing Machines.
1, FREDERIC SMITH, of Caledonia Works, Halifax, in the County of York,
Wire Manufacturer, do hereby declare the nature of this invention, which has been
communicated to me from abroad by Jacques Manne, of Anderlecht, near Brussels,
in the Kingdom of Belgium, Engineer, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to continuous wire rod and tube drawing machines where
a rod or wire or tube or two or more rods or wires or tubes are drawn through a
series of dies simultaneously and the object of the invention is to facilitate the
operation of wrapping the rod or wire or tube (hereinafter designated the wire) on
to the successive drawing through rollers without removing the dies from their
positions in the machine.
The accompanying two sheets of drawings illustrate a convenient arrangement
of parts for carrying the invention into effect.
In these drawings,
Figure 1 is an elevation showing the collar or rib on one of the drawing through
rollers.
Fig. 2 is a front elevation and Fig. 3 an end elevation of the clip and gripping
mechanism on one of the drawing through rollers.
The collar or annular rib A is formed round each drawing through roller B at
or about mid-length, and on this collar A is fitted a grooved clip C the free ends of
which are turned up to form snugs or ears D D¹ through each of which is cut a
slot. These slots may be at right angles to one another and through them is passed
a metal link F or équivalent connection; in a hole at each end of the link F is
fitted a stud G G₁ upon which is secured eccentrically a disc H H', these
* eccentrics H H' serving to clamp the clip C on to the roller B and to draw the
wire into the machine in the following manner:-
The first eccentric H is furnished with a projection or handle I and by moving
this the larger eccentric portion of the eccentric H is brought against the ear D
thereby causing the clip C to grip the rotating roller B slightly but not sufficiently
to cause the clip to rotate with the roller. To the eccentric H' at the other end of
the link F is rivetted or otherwise secured at or about mid-length a bar K which
has a hook at each end, if two series of dies are employed in the machine. The
wire to be drawn has a point made upon it, it is then passed through the first die
and its end is placed and tightly gripped in the jaws of a clamp L. When the
clamp L is by a short chain L' hooked on to one end of the hooked bar K, which
is in line or thereabouts with one series of the dies, the second eccentric H' to
which it is secured, turns upon its stud G' and brings its larger eccentric portion
against the second ear D' of the clip C. This is sufficient to set the clip in motion
and the resistance it encounters in drawing the wire through the die acts on the
bar K and draws it into such a position as to increase the pressure of the
eccentric H upon the ear D' in proportion to the amount of resistance which
the clip C has to overcome, thereby causing the clip to close firmly upon the
drawing through roller B and rotate positively with it thus drawing the wire
forward and wrapping it on to the roller for the desired number of times.

page_text: A bar is then laid across the frame, and pushed toward the clip, and as soon as
the handle I comes into contact with the bar, the handle is knocked back thereby
turning the eccentric H away from the ear D and releasing the clip C.
The action of the clip being thus stopped, the wire is released by opening the
jaws of the clamp L the end of the wire is reduced and the point passed through
the second die and into the clamp L on the clip C on the second drawing through
roller B the drawing in action being repeated as described above and so on in like
manner until the wire finally reaches the winding on drum or bobbin and the
operation of continuous drawing proceeds.
the
A second wire can be introduced into the machine by the use of the same series
of clips without interfering with the action of the machine and for this
second hooks on the bars K are employed.
purpose
If it be desired to draw more than two wires simultaneously through the machine
the hooked bars would be extended to come in line with all the series of dies;
also two or more clips could be fitted on each drawing through roller if desired.
In cases where rods or tubes of large diameter are being drawn through a single
die the same clip device may be employed on a single drawing through roller and
coupled by a chain of sufficient length to the rod or tube.
In place of the collar or rib A on the drawing through roller B and corre-
sponding annular groove in the clip C the groove might be in the roller and the
collar or rib in the clip or any other suitable device for the same purpose may be
employed; also instead of eccentrics, cam levers might be used to lock each
clip C.
Having now particularly described and- ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a machine for continuous wire drawing, the combination with each drawing
through roller of a clip or clips, each clip being fitted and mounted so as to be
capable of being closed to rotate with its drawing through roller and draw along
the wire for a given period of time or opened to remain stationary independently of
such roller all arranged and operating substantially as herein set forth for the
purposes specified.
2. The combination with a drawing through roller, of a clip for gripping the
wire, said clip being fitted on a collar or equivalent device and arranged to be
closed on the roller to rotate with it by means of two eccentrics or cam levers one
of which is worked by hand and the other by the drag of the wire, all arranged
and operating substantially as herein set forth for the purposes specified.
3. The combination and general arrangement of parts embodying the improve-
ments in wire drawing machines substantially as and for the purposes herein described
with reference to the accompanying drawings.
