Improvements in Wire Drawing Machines.
We, FREDERICK SMITH AND COMPANY, Wire Manufacturers, Limited, of Caledonia
Works, Halifax, in the County of York, do hereby declare the nature of this inven-
tion, which has been communicated to us by Andrès Stangl, of Fiestritz im
Rosenthal, in the Province of Carinthia, Austria, Wire Drawer, 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 improvements in wire drawing machines, and has for its
principal object to objects to prevent or minimise-the-grooving of the surfaces-of-the
drawing-through pulley-or-drums, and to improve the arrangement of the machine se
es-to-economise floor space.
In the accompanying two sheets of drawings-
Figure 1 is a side elevation and Figure 2 a plan of a wire drawing machine con-
structed according to this invention.
In these views, a designates the frame of the machine, b the driving shaft, c.the
fast and d the loose pulley, ef bevel gears for driving a vertical shaft g from the driving
shaft, h the wire drawer's block mounted on the vertical shaft g in the ordinary
manner well understood by wire drawers, i the locking handle for locking and
releasing the block, j the sliding guard for preventing the wire as it is wound on
from slipping altogether off the block and also to increase the capacity of the block,
k designates the brackets which form a holder for a series of six dies placed one above
the other and gradually decreasing in size from the bottom upwards, is a guide
pulley, m the usual dressing comb for straightening the wire, na flanged guide
pulley mounted on the vertical shaft g on which are also secured a series of six drawing
through pulleys 01 02 03 04 05 0º. These pulleys o are flanged and have tapered faces,
and they gradually increase in diameter from the smallest o' to the largest, o*.
In a lubricating tank p is a horizontal shaft q and on this shaft are mounted loosely
a series of seven grooved guide pulleys, 81 to 87 and outside the tank on vertical
pillars t another series of flanged guide pulleys u¹ to uº.
In a lubricating tub or tank w is mounted on a spindle x the creel y from which
the wire z to be drawn is coiled.
The wire is led from the creel y through a staple v over and round the first guide
pulleys through the bottom and largest die in the holder k round the bottom and
smallest tapered drawing through pulley o¹ thence back to the first guide pulley u',
round it to the second pulley 82 through the second die in the holder k round the
second drawing through pulley o² and so on until from the last pulley and the
pulley & the wire is led over a flanged guide pulley r round the pulley n and pulley 1,
through the dressing comb m to the wire drawer's block h upon which it is wound in
the usual way.
From the drawings and foregoing description it will be readily understood that the

page_text: grooving of the surfaces of the drawing through pulleys o is prevented or minimised
by their tapered formation which causes the wire to spread or slip along the surface
toward the smallest diameter and so obviates the grooving caused on a parallel drum
by constant wear in one position.
It will also be obvious that by arranging the dies and drawing through pulleys
vertically as shown a very neat and compact arrangement is obtained and floor space
is greatly economised.
I am aware that tapered drawing through pulleys have already been used with
a view to reduce liability to grooving, also that vertical drawing through pulleys
with vertically placed dies have already been used and therefore I do not wish to
claim such broadly.
Having now particularly described and ascertained the nature of this said invention
and in what manner the same is to be performed we declare that what we
claim is :-
1. Forming the drawing through-pulleys-with-tapered-frees-in--order to obvinte
grooving-substantially-as-herein-set forth.
2.
Arranging-the-series-of-tapered-drawing-through-pulleys-on-a-vertical-axis-in
combination with-a-series-of-vertically-placed dies-and-means-for-guiding-the-wire
substantially-us-and-for-the-purposes-herein-set-forth.
3. The general arrangement, construction and combination of parts constituting
an improved wire drawing machine substantially as and for the purposes herein
described with reference to the accompanying drawings.
Dated this 11th. day of September. 1899.
