There are many times when it is advantageous
40
to twist material to form braid, carpet material
and the like. This is sometimes done by fasten
ing the ends of material to be twisted to a door
knob or similar fastening point, and to then twist
4 UT
the material by hand gradually walking away
from the starting point as the twisted portion in
creases in length. This is a very tedious process,
and does not give a uniform twist, and, therefore,
We have produced a device that can be attached
50
to the ordinary sewing machine hand wheel, and
by rotating this hand wheel through the custom
ary movement of the sewing machine, we are
enabled to easily and accurately twist material
to any desired length and with a minimum
55. amount of e?ort.
sections II, and then further twisted together,
as at l2. The parallel sections I l engage the in
ner surface of the spool hub I3. (See Figs. 3
and 4). This spool hub is provided with ends
l4 and I6 and thus form an ordinary spool. A
slot I‘! is formed in the end l4, and a hook I8
is secured adjacent thereto. When the spool is
entirely upon the device the twisting point l2
projects beyond the outer surface of the spool of
the end M.
In the modi?ed forms shown in Figs. 6 and 7,
the construction is identical with the exception
that the hooked ends ‘I of Fig. 1 are reversed,
so that they engage the outer periphery of the
whee1'5, as indicated at A. The same numerals
have been applied for the remaining parts.
In the modi?ed form shown in Fig 8. the only
difference is that we use sliding clips l9 instead
of the wire hooks l, and employ a twisting point
B which corresponds to the twisting point [2 of
the preferred form of our invention.
In use the device is attached to a fly wheel of
a sewing machine, and the material to be twisted,
as for instance the cord C of Fig. 5, is hooked
over the hook I8 and brought through the slot
l1 and into engagement with the twisting point
I2. The machine is then started, and as a rule,
the cord C will be twisted upon itself between
the end of the spool and the point where it is
being held by the ?ngers. As soon as this occurs,
the operator leaves the twisted part upon the 4
spool and then proceeds with a further twisting
operation. Thus by rapid twisting a long length
of twisted material may be easily formed.
It is to be understood that the form of our
invention herewith shown and described is to be
taken as a preferred example of the same and
that various changes relative to the material,
size, shape and arrangement of parts may be re
sorted to without departing from the spirit of
the invention or the scope of the subjoined claims. 55

Having thus described our invention, we
claim:—
.
1. In a device of the character described, a
spool, means for securing said spool to a rotating
member and in axial alignment therewith, said
spool having a twisting point connected thereto
and extending therefrom and in axial alignment
with said spool, and means for holding material
to be twisted by said spool, whereby rotation of
10 said spool wille?ect a'twisting of the material.
2. In a device of the‘ character described, a plu
rality of wires secured one to the other, said wires
having arms diverging and terminating in hooked
extremities, the opposite ends of said wires ex
tending in parallel relation and having their free
ends in turn twisted together, whereby a spool
mounted on said parallel portions will be held
thereon, whereby rotation of said spool may be
effected.
