Improvements in Apparatus for Manufacturing Wire Coils for 'Use
in Flexible Shafting.
We, ADOLPH STRIEMER, Merchant, of 5 Gontardstrasse, and LEOPOLD
GERECHTER, Manufacturer, of 43 Rosenthalerstrasse, both in Berlin, in the
German Empire 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, reference being had to the accompanying
drawings and to the letters and figures' marked thereon, that is to say:-
This invention relates to improvements in apparatus for manufacturing wire
coils, having two or more separate wires, for use in connection with flexible
shafting.
In manufacturing these wire coils or spirals, the wires for use therein are,
according to this invention, passed separately through or over a hollow shaft
which is provided with suitable guides or grooves to receive them.
The hollow shaft is fitted at rear with a spool-carrier arranged to hold the
required number of spools. The opposite end or front of this shaft is provided
with a head for causing the wires to be wound upon a mandrel arranged in the
interior of the hollow shaft and adapted to advance gradually with the finished
part of the coiled wires. The spools and the head are so constructed as to prevent,
as much as possible, all friction and bending or kinking of the wires in the guides
or grooves. The wires pass from such grooves over two rollers on the head, and
into a device for guiding them onto a mandrel.
And in order that our invention may be readily understood, we will describe the
same fully with reference to the accompanying drawings, in which :-
Fig. 1 is a side elevation, and
Fig. 2 a front elevation of the improved apparatus.
Fig. 3 is a longitudinal section of part of the hollow shaft and connected parts,
drawn to a larger scale.
Fig. 3 is a cross section of the same.
Fig. 4 illustrates the mode of guiding the wires at the head of the apparatus.
Fig. 5 is a rear view of the apparatus showing the spool carrier which, in this
instance, is adapted to carry four spools.
Figs. 6 and 7 show the construction of the spools.
Figs. 8 and 9 show the wire guiding device which is fitted to the head of the
apparatus.
The hollow shaft consists of two tubes k and arranged one within the other.
To the outer tube are fitted a spool carrier n, a head e, and bearings w. It is also
provided with lateral slots m, m', which lead to the interior. The inner tube lis
provided with a winding mandrels and with guides or grooves i for the wires.
The spools containing the wires for use in manufacturing the coils, are mounted
on, pins o in the carrier n. These spools consist of two discs q, mounted on a
boss q, and having arranged between them a spring band or ring q'. This ring is
made in the form shown in Fig. 7, and has its ends overlapping; one end being
ith a mids min danted to work in a clot in the other end
