COMPLETE SPECIFICATION.
Improved Machinery for Making Springs for Covering Telephone,
Electrical, and other Wires, or Making Strings of Musical
Instruments.
We, JOSEPH BAIER, Engineer, CHARLES BORNHAUSER and CLEMENT
LAMBARD, Commercial Travellers, all of 3 Richmond Buildings, Dean Street,
Soho, London, 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 :-
This invention refers to an improved machine for making small spiral springs or
tubes, and for covering wires with threads of cotton or other substances.
We will now describe it with reference to the accompanying drawings in
which
Fig. 1 shews a plan view of the machine with belt for driving the same.
Fig. 2 shows a side view of the same, and displays the mode in which the coiled
wire is wound off from the mandril after being twisted.
Fig. 3 shows an enlarged end view of the mandril, partly in section, the bobbin
being shewn in dotted lines.
Fig. 4 shows an enlarged side view of the mandril, when the machine is winding
one wire over another.
Fig. 5 shows an end view of our machine with winding roller removed.
Fig. 7 shows an end view of the machine when cog wheels are employed for
driving, and when two or more separate sets of wires can be twisted at once.
Fig. 8 shows a plan view of Fig. 7 with attachment for twisting the wire
omitted.
Fig. 9 shows a modified form of mandril.
Fig. 10 shows a plan view of adjustable plate y, with holes for guide y¹.
Fig. 11 shews an enlarged end view of guide y'.
a, is the table or base of our machine. b, b, are brackets supporting the driving

wheel c.
c, is the driving wheel which is driven by the crank handle c'. d, is the
driving belt which transmits motion to the flanged wheel e, by which the wire is
twisted. e, is the flanged wheel by means of which the mandril is rotated and so
twists the wire. f, f, are brackets supporting the wheel e.
9, 9, are brackets
supporting the feed wheel h. g', is a crank handle for turning same. h, is the
flanged feed wheel which feeds the wire to the mandril. is an adjustable spring
which governs the speed of the feed roller. j, is another wheel which in conjunction
with wheel, weight k¹, and hooks k², serve to keep the wire tight before and after
it is wound. 7, is the mandril. 1, is an adjustable eyed bolt through which the
wire is wound. 13, is another bolt which serves to adjust the plate 2, to any size of
wire., is a hole in the face of the mandril, by which the twisting is effected.
m, is a curved arm which may either be bolted or screwed on to the hollow tube n,
which guides the wire to the mandril. m', m' are small eyes on the arm m, serving
as guides for the wire to the mandril. n, is a tube forming a guide for the feed
wire off wheel h. o, is a loose bobbin from which the wire is taken to be twisted
round the wire from the feed wheel h. p, is a thin sheet of brass serving to keep
the bobbin o, in its place, and is secured to the curved arm m by the bolt p².
2, 9, are curved arms supporting shaft r. ", is a small shaft supporting wheels k, s.
s, is the roller upon which the wire is wound after being twisted. v.. Fig. 7 is a
cog wheel which can be used in place of the driving band and pulley c, d. v¹, v', are
two smaller cog wheels driven by the cog wheel v. r, is an endless worm screw
mounted on the centre shaft of cog wheel v, and turns the shaft r, by another worm
screw mounted on the same, the weight k¹, being dispensed with when the above
is used.
x, Fig. 9 is a small plate with a hole a³, attached to the mandrill, and forms an
improved means of winding the wire off the mandril in its finished state. ¹, is
another plate similar to the above and has a hole, cut in its under side through
which the wire passes. y, is an adjustable guide plate and has two oblong slots cut
in it and can be adjusted to any thickness of wire by a screwed nut or other means.
y, is an arched guide forming an adjustable eye, and slides to and fro as required
in the slots referred to above, the wire being fed through same to the mandril as
indicated., is another adjustable guide formed in the plate e', and is regulated
by a screwed nut.
In the case of one wire being wound round another. The wire which is to have
another wire round it comes off the feed wheel h, passes through the hollow tube n,
through the two ends of the mandril 7, by which the second wire is wound.
The operation of our machine is as follows:-The crank handle c', is first turned
which rotates the pulley e, tube n, curved arm m, and mandril 1, by means of the
driving belt d. This rotation brings the second wire off the bobbin o, and winds it
round the feed wire. The slot in the bolt l', and guide 1, are made adjustable so
as to suit any size of wire. It will be seen that when the above rotation takes
place the wire coming off the feed wheel 4, is, after being twisted, wound on to the
wheels, in its finished state automatically by means of the weight k¹. This weight
is suspended from wheels j, k, by means of string, or rope, and thus keeps the wire
tight while being twisted.
It may be desirable in some cases to twist two sets of wires at one operation. To
effect this I preferably use the modification shewn in Figs. 7 and 8. In this we use
a large cog wheel v, which when rotated by the crank handle turns two or more
smaller cog wheels v', v', on the centre of each of which is the mandril and its
attachments. If requisite six or seven sets of wires may be wound at one
operation.
On the centre shaft of the cog wheel v, is cut a worm screw, which engages
with another screw cut on the shaft r, and thus turns same. In this case it is
unnecessary to use the weight k¹.
Referring to Fig. 9. This is a modified form of mandril which operates on the
wire in a more certain and direct manner and consists of two plates a, x¹. The
first plater, has a hole a³, cut in it through which the wire passes in its finished

page_text: state. The second plate z', has a hole a, cut in its under side. Above this is an
adjustable guide y³, which can be tightened so as to keep the wire tight. Through
the end face of the mandril 1, an adjustable plate y, is inserted which can be
regulated by the screw as shewn. This plate is provided with two oblong
slots y, y, in which slide an arched guide y¹. The wire is passed through the
different guides as shewn.
It will be seen that any size of wire can be wound, or cotton may be employed
as in case of covering electric wires. Also the winding may be very close or wide
as required.
In the case of making spiral springs the operation is similar to the above, except.
that when the winding is finished the centre or guide wire is pulled out and thus
leaves the hollow spiral spring.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed; we declare that what we
claim is :-
1. The machine for coiling and twisting threads of metal or other material the
combination of parts as herein described and set forth.
2. The machine for coiling and twisting threads of metal or other material, and
for covering wires with thread and for like purposes, the angular mandril 1, the
eyed bolt, guide plates 1, y, the curved arm m, and guides y¹, y, the worm
screw w, engaging with screw on shaft r, with accessory parts, as herein described
and set forth.
