COMPLETE SPECIFICATION.
Compensating Device for Continuous Wire Drawing.
I, EDMUND FRANCIS SMART, Engineer, 68, Corporation Road, Middlesborough,
Yorkshire, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
My invention has for its object to provide efficient means of obviating the
breakages hitherto experienced in continuous wire drawing, to take up and give
out the extra length in the wire being drawn due to the slight irregularity of
the wire given off from one drum to a second drum and succeeding drums.
According to my invention I employ a loose split ring, coned as desired en-
circling the drums, with the bottom edge dropped into a recess in the flange of
the said drum, and a loose plate or another drum fixed above by means of set
pins which efficiently prevents the split ring from getting out of position.
To get over the difficulty of breakages hitherto experienced, in getting the
periphery of the drums to travel at the exact speed, that the wire is given off,
owing to increasing length while passing from one drum through a draw plate
to a second drum, and from a second drum through a second draw plate & round
a third drum and so on which is necessary in continuous wire drawing:-
-
My device or invention if fitted to the said drums will skid on the drum, if too-
much wire is being given off one than is taken up by the succeeding drum, until
the slack or increased length has been drawn on to the succeeding drum when
the wire tightens on the preceeding drum and the drawing of the wire continues
thus obviating the breakages hitherto experienced.
In continuous wire drawing the increase in length of wire, due to the differ-
ence in gauges is allowed for by making the drumis either of different diameters
to suit the increase in length of wire or by variation of the speed of drums of
similar diameters. By the fitting of my invention on to the drums of different
diameters or of similar diameters, variously speeded, breakages are obviated as
aforesaid described.
In order that my invention & the manner in which it may be performed, may
be well understood, I will describe with reference to the accompanying drawing,
a device constructed in accordance therewith.
Figure 1 is a vertical section.
Figure 2 is an elevation.
Figure 3 is a complete plan.
A is a cover plate which is securely fixed to the drum D by means of the 4
set pins C.
B is the coned split ring fitted around the drum D and let into the recess of
bottom flange giving clearance all round, so that ring may have perfect freedom
under all conditions.
The working face of split ring is coned from the top edge to a position level
with the recess in flange of drum whence it is thickened out to a parallel strip
and the intersection is suitably curved which assists the wire to rise on ring
when being drawn.

page_text: These split rings can be attached or used on one or more drums of different
diameters upon the same or different spindles, at the same time speeded to suit
the increased lengths of the wire due to the difference of the gauges after passing
through the draw plate.
Having now particularly described & ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is:-
1. A split coned ring Bencircling a drum which has been prepared to receive this
ring and a cover plate A or second drum to keep the said ring in its position upon
the drum D. The whole of the action being automatic, requiring no attention.
2. A device for compensating the irregularity in the passing of the wire from
one drum to the succeeding one when the wire is being drawn through draw
plates from one gauge to another the said device being constructed substantially
as herein before described and illustrated in the accompanying drawings
Figures 1, 2, & 3.
