Complete Specification Left, 1st May, 1895-Accepted, 27th July, 1895
hereby declare the nature of this invention to be as follows:-
My invention relates to new and useful improvements in wire-drawing consisting
in the arrangement of the drawing plate in such a manner that this instead of being
held fast in its seat is made to be turned more or less backwards and forwards or to
oscillate round its geometrical axis. By this construction I avoid wearing of the
drawing steel or stone on one side only and the hole is kept round instead of getting
oblique, as is the case with fixed drawing plates and with those turning round
continuously in the same direction. I also obtain an easier drawing of the wire.
On the accompanying drawing
Figure 1 is a vertical view of a part of a drawbench, the drawing plates arranged
in pairs;
Figure 2 is a side view seen from the left side of Figure 1;
Figure 3 is a plan;
Figures 4 and 5 are details of construction
Figure 6 shows a modified device for setting in motion the draw plates.
Referring to Figures 1-6 A is a standard in which is journalled the shaft B
running along the draw bench and driving by means of bevil wheels C a number of
vertical spindles D carrying the drawing drums E. To the spindle D is fixed
a worm F, which gears into a worm wheel G on a spindle H. A spur wheel I is
keyed to this spindle and causes by means of another spur wheel K to rotate the
spindle L, carrying on one end a grooved disk M, which by means of the adjustable
pin N and a connecting bar O moves up and down a slide P. In the middle of the
slide P are connected on a pin r arms R forming part of boxes S, which are
arranged to the left and right side of the slide P. The boxes S forming a sort of
a hollow spindle are journalled in suitable brackets T so that their prolongated
geometrical axes touch the circumferences of the drums E and reels R' of the
rawing bench.
Now it is easy to understand that the shaft B, when set in motion, by means of
the intermediate gearing causes the boxes S, containing each a jewel die, such as
diamonds for fine wire, to oscillate round their geometrical axis.
By means of a clutch V and a lever X the grooved disk M may be stopped or
set in motion.
As will be seen from the skeleton Figure 6 the oscillating movement of the
boxes S may be also attained by a rack gearing into corresponding spur wheels
upon the boxes S.
I have arranged the wire-drawing plates in couples being all driven by one spindle,
so that one workman is enabled to attend to a large number of single sets.

In Fig. 1, Sheet IA is a support of the drawing bench carrying the drawing
machines, and being provided with pedestals and bearings for the common motion
shaft B and the vertical spindles D. D. The latter are driven by bevel-wheels C
and have fixed to them at their tops the drums E E. Above the bevel-wheel, the
one spindle D has a worm F fixed to it, which is geared to worm-wheel G driving
an intermediate shaft H with spur wheel J. This latter is geared to spur wheel K
on shaft L Fig. 3. H and L are running in hangers suspended from the table of
the bench. Shaft L is carrying in front a loose crank-disc M with a slot for
allowing the adjustable crank-pin N to be set at different strokes. The crank
pin N is further giving, by aid of a short connecting rod O a reciprocating motion
to a vertical slide P. sliding up and down in suitable guides, this slide is provided
nearly in the middle of its length with a fixed stud or pin Q, see Fig. 1, 3, 4, to
which are articulated by oval eyes both the single and the forked ends of two
levers RR, fixed to the bushes of the two drawing plates carrying the hard steel
or jewel-lies, and being journalled each in two chairs T Fig. 2, 3, 5. These bushes
are parallel to each other, and their centre lines are tangents to the periphery of
the respective drums E and U, which wind-in and give-out the wire. The centre
of the crank disc M is clutched to another clutching bush W, sliding on a key on
shaft L, which can be worked by hand rod X and a forked lever, so as to rotate or
stop the crank-disc M.
I also show in Fig. 6 another arrangement to transmit the reciprocating vertical
movement of slide P* to the bushes journalled in chairs T. In this arrangement

page_text: the slide has uo lateral guides, but it is cogged on both sides to enable it to work
as a rack; the pinions a, b, keyed to the bushes S in the place of levers R, giving
in this way an oscillating movement to the bushes S, around the axis of the wire
centre.
The above described arrangement refers to a range of double wire drawing
machines on one common bench, suitable by preference for the lower gauge numbers
of wire. For making the high numbers of wire-gauge, especially the so called thin
wires, I use a similar arrangement of wire drawing machines for multiple wire
drawing, disposed on one cominon bench and combined in the manner which is
represented on Sheet II. Figs. 7, 8 and 9.
EE are the drawing drums, driven by the vertical spindles D' D' rotated by
the bevel wheels C' C' and shaft B'. On the one spindle D¹ the worm F' com-
municates rotation to the worm wheel G' and shaft H'; the latter has another
spurwheel keyed to it, which gears into pinion K' on shaft L', Fig. 7. Shaft 1.1
is carrying the loose crank-disc M', journalled in the front bearing suspended below
the bench; the crank-disc is clutched to a clutch W sliding on a key on shaft L'.
By a hand lever X° and fork this clutch can be worked to rotate the crank-disc M
or not. The crank-disc is slotted for variable strokes of the adjustable crank-pin N¹ ;
by means of a connecting rod Q', running up vertically, it is coupled to the rod P;
this rod is guided vertically in two bushes arranged in the top and bottom of the
standard frame T', fixed on the table of the drawing-bench, and is provided with
asted, to which are articulated, on the right and on the left, two arms R" R'.
coming from the bushes S. In moving up and down, Pl gives a rocking movement
to Ro and R¹ and oscillates bushes S. These latter drawing-bushes are equally
journalled in suitable bearings of the standard frame T' as well as a further number
of them, marked S1 S2 S is located in bearings above S on the inclined side parts
of frame T', and all these bushes are geared to each other by pinions X, X, X, X,
so as to communicate the oscillations of S to all bushes likewise.
In front of the drawing bench, in brackets Y and opposite to drums E are
mounted on vertical shafts the guide-rolls U, U', U', U³, having like E, E¹ E' E³
different diameters in accordance with the corresponding stretching of the wire,
and the lower roll has the smallest diameter. To the right and left of Y are
supported on brackets Z' the crowns or reels Z. The wire put on the reels passes
first round the smallest guide roll U through the bush S, goes round the drawing
drum E and rises to the next greater size roll U¹, wherefrom it passes further by
the second finer drawing die S₁ and is wound on drawing drum E, and so on until
it has attained the desired fine number by the last drawing die from where it is
wound up on E*.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare, that what
I claim is:
1) A wire drawing arrangement, wherein the drawing iron is oscillated, the axis
of oscillations being the centre of the wire.
2; In a wire drawing arrangement as at 1) actuating the oscillation of the bushes
carrying the drawing irons or the dies or jewel-dies by rocking levers R R',
receiving motion from a stud or pin on a reciprocating slide P or by a reciprocating
rack P* working two pinions a, b, geared to the spur wheel keyed to the bushes,
Fig. 1-6.
3) A form of wire drawing arrangement as under 1) and 2) characterised by the
combination of worm F' on spindle D', driving shaft, H' and wheel J¹ driving
wheel K' and thereby shaft L' and disc M', and by pin N' and rod Q₁ the slide P¹
and by levers R R the first bushes S; and the latter in their turn by pinions
gearing into those on drawing dies S¹ S*. in giving them rocking or
oscillating movement, whereas S: S' are disposed each between a drum and a
roll, E-U, E'-U³, E³—U³ . . . . . so arranged one pair above the other, that
•

page_text: the wire is drawn at one and the same pull through any desired consecutive number
of drawing-dies.
