page_text: blocks B' secured by screws or bolts v, to the plate in which groove is adapted to
fit a correspondingly shaped tongue C₁ on the under side of a plate or block D'
which is in the form of a segment of a flat ring or rim, and which supports and
carries a bobbin, the plate being arranged to freely travel around in the groove
and prevented from escape therefrom by the lips.
There are two of these carrier plates, diametrically opposite to each other as
shown in Figure 7, and the inner edge of each has an internal gear E which is
adapted to engage with the four small gears R each plate being of a length for its
internal gear to extend from the centre line of one gear R to the centre line of the
next or adjacent gear R, so that the movement of each carrier plate in the circular
groove A will be made continuous by the engagement of its internal gear with the
small gears, one after another.
Screwing into the centre of the gear which engages with the bobbin carrier
plate gears R, and passing freely through plate S, is a vertical tubular rod F¹
which although independent of the vertical tubular shaft J forms practically a
continuation of the same, so that there is a vertical central passage (which
extends through the rod and the tubular shaft J and through the base as shown in
section in Figure 3.
Up through this passage G₁ in the operation of the machine, the electric wire, or
cable, or hose, or other article travels in order to be covered with the circular
woven fabric.
H' are the lower or stationary bobbins which are secured in suitable positions
preferably in the form of a circle below the machine on the bench supporting the
machine, or on any suitable support, each carrying a thread a' making the warp
thread, and J¹ are the upper bobbins, one to each bobbin carrier plate and carrying
a thread b' making the woof threads.
K' are a series of radial bars, preferably square in cross section, equal in number
to one half of the warp thread bobbins of which, in the present machine there are
twenty, and each is adapted to move freely forward and back radially in slots d' in
two sets of circular ribs e secured to or made integral with the plate N, the bars
being secured from accidental detachment, by screws b.
On the under side of the inner end of each bar K' is a downwardly extending
pin or projection f which pins are freely disposed in a circular groove L' in the
upper side of the gear W which circular groove is eccentric to the central tube J,
as shown more particularly in Figure 4 in plan.
Each bar K has an extension wire g¹ its end ¹ being bent upwardly at right
angles and is disposed in a socket m¹ in one end of a horizontal lever M centrally
pivoted at n¹ near the outer edge of the plate N.
Each of these horizontal pivoted levers M' has in each end a hole t¹ through
which extends a warp thread a' from one of the lower bobbins H' as shown more
particularly in Figure 2.
In line vertically with and below each hole t¹ in the end of these levers M' is an
open radial slot Ni in the edge of the plate N which slots leave room for the warp
threads to move in the operation of the machine.
Secured by screws e" to the upper side of each bobbin carrier plate is a switch
plate Q made of sheet metal having a pointed end u¹ and its two edges extending
back therefrom in two circular lines concentric with the tubular shaft J, as shown
in plan in Figures 2 and 9.
Each carrier plate has secured to it by screws t¹¹ above the switch plate Q¹ an
upright arm R, which consists of a flat tapering strip u" having on its outer side a
central rib to stiffen it, the arm laying in an inclined direction toward, and
bearing at its upper end close against the tubular rod F'.
Attached to the inclined arm R' or near its top is another switch plate S' but
quite small or short, having a pointed end ' and its edges being circular, as shown
and a short distance below this upper switch plate S is another switch plate T,
but larger, having a pointed end to, the pointed ends of the three switch plates
being substantially in the same inclined plane.

page_text: The upper end of each of these bobbin carrier arms has a vertical passage a" at
one side, through which passes a woof thread b' and its upper edge b above such
passage extends therefrom slightly rising, as shown in Figure 8, and it is hollow or
concave in cross section as shown at in Figure 10.
The bobbin J' is attached to a plate c¹¹ secured to the switch plate at ell and it is
bent upward at an angle for the bobbin to lay in an inclined direction inwardly
toward the rod F' to be substantially in the same inclined direction as the arm R¹,
as shown in Figure 3.
Each bobbin of the warp threads and woof threads has the usual weight and
tension arrangement for the proper delivery of its thread and they are all
constructed and arranged as usual in braiding machines, to deliver and keep the
proper tension on the threads, and as the bobbins and their adjustment can be of
any suitable construction and being no part of this invention it is not deemed
necessary to berein particularly describe such.
The operation of the machine is as follows:-
Each warp thread a' from a lower bobbin is passed up through an eye hole t¹ in
the pivoted lever M' laying in the slot N' from thence they all pass upward through
separate radial slots in the upper plate L between the blocks B' to a point near
the upper end of the tubular rod F where they are all held temporarily in any
suitable manner more or less taut together.
The blocks B¹ are separated sufficiently to leave a narrow space between them
over each radial slot to allow free passage for the warp threads.
The thread from each shuttle bobbin J' passes up through holes g" in the two
switch plates ST and then through the hole a" in the upper end of the arm Ri
laying in the groove 6, in such end, and in starting the machine such threads are
held by hand until the machine has made one or more revolutions when it carries
them along itself.
Turning the pulley in the right direction the mitre gear H is revolved in 'the
direction of the arrow Figure 1, which turns the tubular shaft J and its gearin
the same direction, see arrow w¹ Figure 7, turning the small gears R.in the reverse
direction which correspondingly causes by their connection with the internal
gears E¹ of the bobbin carrier plates D', the carrier plates to travel along their
circular raceway A' in the direction of the arrow h", Figures 2 and 7.
The gear W by its gear connection with the tubular shaft U, is turned in the
opposite direction to the gear Q, carrying the eccentric cam groove L' in the same
direction, see arrow Figure 4, which cam groove causes the radial bars K¹ to move
radially forward and backward in their guide slots and in such movements their
respective pivoted levers M' are swung on their pivots, alternately moving each
arm outward and inward, and in such movements alternatively moving outward and
inward their respective warp threads a', so that as the pointed end u¹ of a switch
plate Q of a bobbin carrier plate, arrives at such threads, it passes between the
two, carrying with it the woof thread 6 of its bobbin, which is carried round
the upper part of the tubular rod F and is woven in and out with the warp
threads.
In Figure 9 is shown in their relative positions in plan view the two switch
plates the bobbins being removed, and the vertical arms R¹ in cross section, the
warp threads also being in cross section and bearing against the two edges a
of the switch plates, and opened or separated from each other forming the shed
through which its respective bobbin carried, and as they so travel each passes
between each two warp threads of each pivoted lever, one after another, at the
same time the eccentric groove L' moves round and causes radial bars K¹ to
gradually move in a direction to swing their pivoted levers M' so as to move the
warp threads connected: therewith, for the outer one of each two, to be moved
inward, and the inner one of each two to be moved outward, so that as the next
bobbin carrier plate and its bobbin comes round it will pass between each two warp
threads, and as the warp and woof threads are woven together at the upper end of
the tubular rod, each warp thread will alternately be outside of and inside of the

page_text: woof threads by which the warp and woof threads will be woren, together in a
similar manner to that in which cloth is woven, except that in the present machine
two woof threads are used and the shed is operated so that each woof thread
passes alternately in front and back of a warp thread in each revolution' or
passage around the machine.
The warp threads as they leave the rear end of each switch plate pass as follows:
the inner threads on to the outer curved edge, and the outer threads on to the inner
curved edge of the next switch plate one after the other.
The levers M' acted upon by the radially moving bars K' from the movement
of the cam groove L' cause the warp threads to separate or open from each other
laterally, sufficiently for the ends of each switch plate Q to enter between them to
form the proper sheds, and to still further ensure that the threads shall open from
cach other at the upper part the switch plates S and T' are added to act upon the
upper portions of the threads so that, with the three switch plates attached to the
bobbin carrier plate and its arm, the warp threads will be fully opened or separated
from each other for the carrier plate, its arm and bobbin, to freely pass between
and not interfere with the warp threads.
As the woof thread leaves the carrier arm, the upward incline 6" of its upper
end lays it closely up against the woof thread just above acting somewhat as the
frame in a loom, and also as a feed to the circular tube, as it is woven in the
machine; it is well however to have the woven tube as it leaves the rod secured to
a device which will assist the feed and pull it upward as fast as it is woven.
The shed of the warp threads for the woof threads is thus made alternately by
the movement of the pivoted levers M' caused by the turning of the eccentric
groove operating upon its connecting bars K' in the operation of the machine.
If an electric wire, or cable, or hose, or any desired article is to be covered with
the woven circular tube, it is passed up through the central passage G¹ and fed
through the same by any suitable feeding device and with the speed required, so
that it emerges from the upper end of the tube the thread will be woven upon it as
fast as it travels upward, the speed of the movement of the wire being governed
by the speed in which the tube is woven, and the closeness in which it is desired
for the threads to lay upon the wire &c.
U is a horizontal plate rigidly secured by screws to the circular plate S and
having V shaped openings in its edge at certain intervals apart, respectively
radially opposite to the open slots NT in plate N as shown in Figure 2, more
particularly, into which openings the warp threads respectively pass as they are
moved backward by the levers to steady them laterally, to facilitate the passage of
the bobbin carrier plate and parts, between them.
The gear
W is cut away on its upper side around its edge for such portion to
fit in the central opening r, in the plate N as shown more particularly in Figures 3
and 4.
The pivoted levers M' serve to separate the warp threads sufficiently to be in
position for the pointed end of the switch plate to enter between them to still
farther separate them for the bobbin and other parts to freely pass between
them.
In Figure 11 is shown on a reduced scale a front view of the arm R' which is
attached to the carrier plate with the lower and upper switch plates Q' and S¹ but
without the intermediate switch plate T₁, for with the lower and upper switch
plates properly arranged in relation to each other for the free passage of the
carrier plate and bobbin between the warp threads, the 'intermediate switch plate
in some cases may be dispensed with.
