COMPLEIE SIEVITICATION,
Elastic Metal Tape and Apparatus for Preparing the same.
We, EMIL OTTO BEYER, Furrier, and JOSEPH BAIER, Tailor, both of
14 Buttesland Street, Hoxton, London, and EDWARD CAMILO PORRO of
18 Newman Street Oxford Street London, Manufacturer of Dental Amalgam,
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 relates to metallic tape constructed of steel wire, to be used as a
stiffener for corsets and other articles of dress worn by women, and for similar
purposes.
In making our metallic tape we employ small wire of tempered steel, and by
preference we use wire of a half round or oval section or nearly so.
We first wind it into small cylindrical rolls or coils by means of the apparatus
hereafter described.
We then pass these rolls between rollers which flatten them into a flat oval
section. After this we place two or more of the rolls together lengthwise in the
same plane, and connect their adjacent edges longitudinally and laterally by means
of a fine binding wire wound between the coils. When placing the rolls together
we arrange them so that the flattened coils of each adjoining roll incline in opposite
directions.
We will now describe the invention and the apparatus for preparing the same
with reference to the accompanying drawings, in which
Fig. 1 shows an enlarged elevation and section of the wire roll n, as formed on
the mandril m, of the twisting apparatus hereafter described.
Fig. 2, n', shows the same after passing through the flattening rollers.
Fig. 3, p, shews the same finished as a metallic tape, two of the flattened rolls
having been bound together by a binding wire, and the whole passed once more
through the flattening rollers so as to become almost flat.
Fig. 4 shows a reduced plan view of the twisting apparatus, a portion of the roll
in process of manufacture being shown at æ, on the mandrils m, m, the wire being
fed by hand from q.
Fig. 5 shews the process of uniting the two rolls which are being fed from the
two reels, placed in the forked holder the binding wire being fed by hand
from q', or otherwise to the point y, as the rolls revolve.
Fig. 6 shows an end elevation of the apparatus. d, is the standard.
is the
large cog wheel fixed on the driving spindle e There are two of these wheels one
at each end of the spindle. is a cranked handle for turning the spindle e. A
pulley for power could be substituted if preferred. b,,, are three pinion wheels
which are rotated by contact with the cog wheel a. Duplicate wheels are placed
at the other end of the apparatus.
Fig. 7 shews a side elevation of the apparatus. d, is a bar connecting the two
standards d. c, c' are forks for holding reels r, upon which the rolls of wire are
wound when formed, passing through the hollow axles of the pinions b, bl.
The fork 2 is wider and holds a larger reel which receives the finished tape.
c3, is a similar fork at the other end of the spindle attached to the duplicate
pinion. This larger fork is used for feeding the rolls when they are being united
as shewn in Fig. 5. When united the finished tape is wound on a reel in the fork c².
m, m, are two wires which serve as mandrils for winding the rolls. k, k, are
thumbscrews for steadying or holding the ends of the wire and the mandrils during
manufacture. 11, is the roll as first formed. n', is the roll after being flattened.
Fig. 8, shows a reduced plan and elevation of a small tool h, which slides on the

9: the loop ', of which regulates by its thickness the space between the annular
convolutions of the rolls.
Fig. 9 shows an enlarged.side and front elevation of the guide tool, which keeps
the flattened wire rolls in their relative positions while being bound together. The
inside oval clip, revolves with the rolls.
The method of manufacturing the wire-tape is as follows:-
One end of the wire being secured by the nuts, and the tool h. Fig. -8 being
placed in position, the handle is caused to revolve and with it the mandrils. in, m.
The workman standing on one side of the apparatus feeds the steel wire as the
mandril revolves thereby coiling it around the mandril, and the tool h, passes along
as the roll increases in length. When the roll is finished the nuts k, ou one side are
unscrewed and the roll of coiled wire is removed from the mandril and wound on
the reels held by the forks c, c'. It is then passed through a, pair of ordinary
flattening rollers, whereby it assumes the shape shewn by 1, Fig. 2.
It is then wound on to one of the reels , on the fork. c³, a reversed roll being
wound on the adjoining reel.
The two flattened rolls are then fed from the reels », r, and are held in position
by the tool, and are caused to revolve as they unwind from the reels.
As the rolls pass along the apparatus they are bound together by a wire fed from
the coil, held by the workman, which wire passes through the convolutions of the
roll.
Finally the nuts k, are again relaxed and the rolls are wound on the reels held
by the fork, after which they are again passed through the flattening rollers, when
they assume the shape shewn by Fig. 3, p.
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 manufacture of twisted or wound, and compressed elastic metallic tape
from steel wire preferably of nearly or quite oval or half round section, as herein
explained and set forth.
2. The apparatus for winding or twisting metallic wire tape containing the
arrangement and combination of parts as herein explained and set forth.
