PROVISIONAL SPECIFICATION.
Improved Machine for Making Braided Cordage.
I, WILLIAM HENRY MUNNS, of 106, 107, and 108, Victoria Chambers, 55 and
56 Chancery Lane, in the County of London, Patent Agent, do hereby declare the
nature of this invention (a communication to me from abroad by John Edward
Warner, of Norwich, Connecticut, U.S.A. Gentleman,) to be as follows:-
:-
My said invention is in that class of cordage-machines in which a series of
bobbins are carried around a common centre and at prescribed intervals are caused
to travel around each other to interlace or braid together the multiple of strands
carried by said bobbins.
The object of my invention is to provide a cordage machine that shall be durable
and less noisy than many of the machines now in use and by means of which the
tension of the threads as they are successively laid up and interlaced may be easily
controlled, as hereinafter explained.
The bed of my machine is supported by legs and provided with uprights on
opposite sides of said bed. Depending from the bed on opposite sides are bearings
in which are journalled horizontal shafts, the former of which constitutes the
driving-shaft of the machine and bears on its outer end fast and loose pulleys. On
the inner end of the shaft is a bevel-gear that meshes with a larger bevel-gear,
secured to a hollow vertical shaft that extends upward through the bed, and is
supported at its lower end in a journal-bearing that may be held in position by the
franie suspended beneath the machine, or may be secured to the floor. A shaft
bears on its inner end a bevel-gear that meshes with the larger gear already
described, and has on its outer end a mitre-gear that is in mesh with a companion
gear secured to a vertical shaft, said vertical shaft being provided to transmit
power and motion to any suitable take-up mechanism.
A tubular guide is located immediately over the centre of the bed, and through
this guide the finished cord passes to the take-up.
A shipper and operating-lever, by means of which the belt may be thrown from
the fast to the loose pulley, and vice versa, are provided at the right hand of the
machine..
The cordage-machine herein described is intended to be used in the manufacture
of cord of twelve strands. The bed of the machine may be briefly described as a
stationary disc having twelve turn-tables seated therein and provided with channels
or grooves that describe three intersecting squares, whose corners are at the centres
of said turn-tables. For convenience in planing out said channels they, in fact,
extend to the outer edge of the bed; but in the manufacture of cord the bobbin-
carriers travel in said channels only to the perimeter of the turn-tables. That side
of each of the channels that is farthest from the common centre of the machine is
undercut, and the corresponding channels in the turn-tables are similarly undercut.
My bobbin-carrier consists of a bar adapted to fit and slide in the channels, and
having a longitudinal rib that enters the described under-cut in the bed and turn-
tables. The bar has secured to its upper edge an anti-friction roller that is engaged
when the machine is in use by one of four arms that project radially from a disc
secured to and carried by the upper end of the hollow vertical shaft at the centre of
the bed. These radial arms travel around with a regular steady movement and at
stated times engage the rollers and move the attached bobbin-carrier forward
through the channels to the turn-table at the other end or angle of said channels.
The bobbin is seated on a plate secured to the bar and projecting upward from the
same plate is a forked arm, to which is hinged a lever whose lower arm extends

page_text: When the
downward and is connected with the arm by a spiral spring that tends to draw said
lower arm toward the said forked arm. The upper arm of the lever is formed with
an opening, in which is a coarsely-threaded rod having secured to its upper end a
milled head, by means of which said threaded rod may be rotated.
thread is delivered from the bobbin it is passed one or more turns around the rod
to give the desired tension, and then passes upward to the tube where it meets and
is interlaced with the several threads from the other bobbins of the series.
The turn-tables are locked when not in the act of rotation by a sliding bolt, that
is seated in one of the channels outside of the square in which the carriers slide,
said bolt being pressed normally toward the turn-table by a spiral-spring whose
outer end abuts against a plate secured to the bed. When a bobbin-carrier is
moved forward into the turn-table by the arm the end of its bar abuts against the
end of the bolt and moves and holds it out of locking-engagement with the turn-
table until said turn-table is rotated a quarter of the way around, when said bolt
shoots forward into the next channel and again serves as a lock to prevent the
undue rotation of the turn-table. When said bar is pushed forward into the turn-
table by its arm it (the bar) is kept from moving backward in the main channel by
a spring-actuated pawl or stop that drops in the rear of said bar as it passes. If
this pawl or some equivalent stop was not provided the bolt would force the bar
rearward in its channel the instant the arm left the anti-friction roller, and would
thus lock the turn-table against rotation. The arms are held normally outward by
springs, one end of said springs being attached to a stud or screw in said arm, the
other end being secured by a screw to the disc or to a plate carried by said disc.
A slot in said plate through which screw projects allows a limited endwise move-
ment of the arms. It will now be apparent that means must be provided to partially
rotate the turn-tables at stated times to permit the arms to reach the roller and
move the bobbin-carrier forward in its proper channel. This is done by positive
mechanism on the under side of the bed, the necessary power and motion being
communicated by a disc that is secured to and travels with the central shaft, and is
formed with a sinuous or serpentine cam-groove near its perimeter. The turn-
tables are shouldered down to fit in the counter-bored bed, and secured to their
lower ends are both ratchet and cam discs, respectively, the latter being provided
with four breaks or deflections in its annular groove. This cam-groove receives
the end of an arm projecting laterally from a bar which is seated in the bed and is
free to be raised or lowered by a cam to bring at the proper time a cam-switch into
the path of a roller carried by the arm.
When it is desired to leave a bobbin-carrier in the turn-table, as is necessary at
stated times in braiding, one of the said switches is raised by a cam-groove, and as
the arm advances its roller engages said switch and the arm is moved inward
against the force of a spring, and its end is thus carried past the roller on the
bobbin-carrier, leaving said bobbin-carrier in the turn-table.
The lever arm is secured to the under side of the bed by a pivot-screw, and has
at its inner end an anti-frictional roller that enters the serpentine cam-groove
already described.
The opposite end of the lever has pivoted thereto a lever whose shorter arm
forms a pawl to engage the teeth of the ratchet-disc. The longer arm of the lever
curves around the said ratchet-disc and engages a stud that is attached to the bolt
and projects downward through a slot in the bed. A spring is secured to the arm,
bears on the short or pawl end of a lever and tends to hold said pawl in engage-
ment with the ratchet-teeth. A detent secured to the bed is provided to prevent
backward rotation of the ratchet-disc and connected turn-table. When the machine
is in motion the levers are being constantly rocked on their fulcra by the serpentine
cam-groove and the described pawls engage one tooth of the ratchet-discs at each
complete movement of the ratchet-levers, thus slowly rotating the turn-tables until
a quarter-turn has been completed, when the forward movement of the bolt causes
its attached stud to force the longer arm of the lever inward. This throws the
shorter or pawl end out of operative engagement with the ratchet-teeth, and for a

page_text: time said pawl moves forward and backward idly. When, however, a bobbin-
carrier is moved into the turn-table and the bolt is pushed outward by it, the pawl
is again allowed to engage the ratchet-teeth and immediately begins to rotate said
turn-table another quarter of a revolution. It will thus be seen that the entering
of the bobbin-carrier in a turn-table acts to throw out the bolt, and that such
movement of the bolt allows the pawl to engage the teeth of the ratchet, and that
the constantly oscillating pawl serves to rotate or partially rotate the turn-table
to allow the bobbin-carrier to depart by the proper channel. The cam-switches
also provide automatic means for controlling the arms to cause said arms to take
the bobbin-carriers from the turn-tables or leave them there, as may be necessary,
and it will be obvious that if the several described mechanisms are properly timed
relative to each other certain bobbin carriers and their threads may be carried
beneath or between other threads at proper times to interlace or braid together
said threads into a single perfect cord.

COMPLETE SPECIFICATION.
Improved Machine for Making Braided Cordage.
I, WILLIAM HENRY MUNNS, of 106, 107, and 108, Victoria Chambers, Chancery
Lane, in the County of London, Patent Agent, do hereby declare the nature
of this invention (a communication to me from abroad by John Edward Warner,
of Norwich, Connecticut, U.S.A. Gentleman) and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
statement:-
My said invention is in that class of cordage-machines in which a series of
bobbins are carried around a common centre and at prescribed intervals are caused
to travel around each other to interlace or braid together the multiple of strands
carried by said bobbins.
The object of my invention is to provide a cordage-machine that shall be durable
and less noisy than many of the machines now in use and by means of which the
tension of the threads as they are successively laid up and interlaced may be easily
controlled, as hereinafter explained.
In order to more readily explain the said invention, I have provided the
annexed set of drawings, illustrating the same both as a whole and in detail, in
which―
Figure 1 is a side elevation of a machine of my new construction having two of
the bobbins and their carriers in place on the bed of the machine, also showing the
manner in which the several threads are brought together at the top of the machine
and delivered to a suitable take-up.
Fig. 2 is a top view, somewhat enlarged, of the bed of a machine of my simplest
form; and Fig. 3 is a plan of the reverse or under side of said bed.
Figs. 4 and 5 show end and side views, respectively, of the bobbin-carrier which
I use, each having a bobbin seated thereon.
In Figs. 6 and 7 are shown sections of the machine-bed on an enlarged scale,
intended to explain, in connection with the Specification, different positions assumed
by the bobbin-carriers and the arms that serve to move said carriers at stated times
from place to place on the said bed.
Fig. 8 is an elevation or side view of one of the switches, or perhaps more
properly turn-tables, by means of which the bobbin-carriers are deflected in their
courses, and shows the manner in which said turn-tables are rotatably supported
in the machine-bed. This said view also shows a portion of one of the arms
by which the said carriers are moved and a cam-switch used to operate with said
arm under certain conditions to prevent it from engaging with and moving said
carriers.

page_text: Fig. 9 is a bottom end view of the turn-table shown in Fig. 8; and Fig. 10 a
central vertical sectional view of the same, taken on line za of Fig. 9.
of Fig. 2.
Fig. 11 is a central vertical section of the machine-bed on line
Figs. 12, 13, and 14 illustrate a certain modification of my invention, by means
of which the radial arms which move the bobbin-carriers are moved outward or
inward positively at the proper time instead of depending on the cam-switches
shown in Fig. 8.
Said Fig. 12 is a plan view of a portion of the machine-bed, showing a fixed
gear at the centre of the said bed, around which travel a series of smaller gears
having attached thereto a corresponding series of cam-discs, the said small gears
and cam-discs being arranged to rotate on studs that are secured to the under side
of a large disc, which is removed in Fig. 12, but is shown inverted in Fig. 13. This
disc is grooved radially to receive and guide the series of arms that move the
bobbin-carriers and is secured to and rotates with an upright driving-shaft in the
centre of the machine, as shown in Fig. 14, which latter is a vertical sectional view
on line y y of said Fig. 13.
Referring to the said drawings, 20 denotes the bed of my machine, the same
being supported by legs 21 and provided with uprights 22 on opposite sides of said
bed. Depending from bed 20 on opposite sides are bearings 23 231, in which are
journalled horizontal shafts 24 241, the former of which constitutes the driving-
shaft of the machine and bears on its outer end fast and loose pulleys 25 25'. On
the inner end of shaft 24 is a bevel-gear 26, that meshes with a larger bevel-
gear 27, secured to a hollow vertical shaft 28, that extends upward through bed 20
and is supported at its lower end in a journal-bearing that may be held in position
by the frame 22, suspended beneath the machine, as here shown, or may be secured
to the floor. Shaft 24' bears on its inner end a bevel-gear 29, that meshes with
the larger gear 27, already described, and has on its outer end a mitre-gear 30, that
is in mesh with a companion gear 30', secured to vertical shaft 31, said vertical
shaft being provided to transmit power and motion to any suitable take-up
mechanism.
32 denotes a tubular guide located immediately over the centre of bed 20, and
through this guide the finished cord passes to the take-up.
A shipper 33 and operating-lever 331, by means of which the belt may be
thrown from the fast to the loose pulley, and vice versa, are shown at the right hand
of the machine in Fig. 1.
The cordage-machine here illustrated is intended to be used in the manufacture
of cord of twelve strands. The bed of the machine may be briefly described as a
stationary disc having twelve turn-tables seated therein and provided with channels
or grooves that describe three intersecting squares, whose corners are at the centres
of said turn-tables. For convenience in planing out said channels they, in fact,
extend to the outer edge of the bed; but in the manufacture of cord the bobbin-
carriers travel in said channels only to the perimeter of the turn-tables. Said
channels are indicated by 34, and their general arrangement relative to each other
and to the turn-tables (denoted by 35) is best seen in Fig. of the drawings. That
side of each of channels 34 that is farthest from the common centre of the machine
is undercut, as clearly shown in Figs. 1 and 11, and the corresponding channels in
the turn-tables are similarly undercut, as shown in Figs. 8 and 10.
My bobbin-carrier consists of a bar 36, adapted to fit and slide in the channels 34
and having a longitudinal rib 36', that enters the described under-cut in the bed
and turn-tables. Bar 36 has secured to its upper edge an anti-friction roller 37,
that is engaged when the machine is in use by one of four arms 38, that project
radially from a disc 39, secured to and carried by the upper end of the hollow
vertical shaft 28 at the centre of the bed 20. These radial arms travel around
with a regular steady movement and at stated times engage the rollers 37 and move
the attached bobbin-carrier forward through channels 34 to the turn-table at the
other end or angle of said channels. The bobbin 4) is seated on a plate 41, secured
to bar 36, and projecting upward from the same plate is a forked arm 42, to which

page_text: is hinged a lever 43, whose lower arm extends downward and is connected with
arm 42 by a spiral spring 45, that tends to draw said lower arm toward the said
forked arm 42. The upper arm of the lever 43 is formed with an opening, (sec
Fig. 5,) in which is a coarsely-threaded rod 46, having secured to its upper end a
milled head 47, by means of which said threaded rod may be rotated. "When the
thread 46' is delivered from bobbin 40, it is passed one or more turns around the
rod 46 to give the desired tension, and then passes upward to the tube 32, where
it meets and is interlaced with the several threads from the other bobbins of the
series.
The turn-tables 35 are locked when not in the act of rotation by a sliding bolt 48,
that is seated in one of the channels 34 outside of the square in which the carriers
slide, said bolt being pressed normally toward the turn-table by a spiral spring 49,
whose outer end abuts against a plate 50, secured to bed 20. When a bobbin-
carrier is moved forward into the turn-table by arm 38, the end of its bar 36 abuts
against the end of bolt 48 and moves and holds it out of locking engagement with
the turn-table until said turn-table is rotated a quarter of the way around, when
said bolt shoots forward into the next channel and again serves as a lock to
prevent the undue rotation of the turn-table. This is perhaps best illustrated in
Figs. 6 and 7. In Fig. 6 the bar 36 of the carrier is shown as if advancing across
the turn-table and just about to engage and push back the bolt 48, while in Fig. 7
the turn-table has been rotated a quarter-turn and the bolt has entered the next
channel. In these figures the bar 36 is shown with plate 41 removed. When said
bar is pushed forward into the turn-table by arm 38, it (the bar) is kept from
moving backward in the main channel by a spring-actuated pawl or stop 51, that
drops in the rear of said bar as it passes. If this pawl or some equivalent stop
was not provided, the bolt 48 would force bar 36 rearward in its channel the
instant arm 38 left the anti-friction roller 37, and would thus lock the turn-table
against rotation. Arms 33, as illustrated in Figs. 2, 6, 7, and 11, are held normally
outward by springs 52, one end of said springs being attached to a stud or screw 53
in said arm, the other end being secured by screw 54 to the disc 39 or to a
plate 55 carried by said disc. A slot in said plate 55, through which screw 53
projects, allows a limited endwise movement of the arms, as will be understood by
reference to Figs. 6 and 7. It will now be apparent that means must be provided
to partially rotate the turn-tables 35 at stated times to permit arms 38 to reach the
roller 37 and move the bobbin-carrier forward in its proper channel. This is done
by positive mechanism on the under side of bed 20, as best seen in Fig. 3, the
necessary power and motion being communicated by a disc 56, that is secured to
and travels with the central shaft 28 and is formed with a sinuous or serpentine
cam-groove 57 near its perimeter. The turn-tables 35 are shouldered down to fit
in the counterbored bed 20, (see Fig. 8,) and secured to their lower ends are both
ratchet and cam discs 58 and 59, respectively, the latter being provided with four
breaks or deflections in its annular groove. This cam-groove receives the end of
an arm 60, projecting laterally from a bar 61, which is seated in bed 20 and free to
be raised or lowered by cam 59 to bring at the proper time a cam-switch 62 into
the path of a roller 63, carried by arm 38, as is best illustrated in Fig. 8. These
cam-switches 62 are also seen in Figs. 2, 6, and 7. When it is desired to leave a
bobbin-carrier in the turn-table, as is necessary at stated times in braiding, one of
said switches 62 is raised by cam-groove 59, and as arm 38 advances its roller 63
engages said switch and the arm is moved inward against the force of spring 52,
and its end is thus carried past the roller 37 on the bobbin-carrier, leaving said
bobbin-carrier in the turn-table.
Referring now to Fig. 3, 64 denotes. a lever-arm secured to the under side of
bed 20 by pivot-screw 65 and having at its inner end an anti-frictional roller that
enters the serpentine cam-groove 57, already described.
The opposite end of lever 64 has pivoted thereto a lever 66, whose shorter arm
forms a pawl to engage the teeth of ratchet-disc 58. The longer arm of
lever 66 curves around the said ratchet-disc and engages a stud 67, that is attached

page_text: to the bolt 48 and projects downward through a slot 68 in bed 20. (See also left-
hand side of Fig. 6, which shows said bolt partly cut away to expose slot 68 in the
bed beneath.) A spring 69 secured to arm 64, bears on the short or pawl end of
lever 66, and tends to hold said pawl in engagement with the ratchet-teeth.
A detent 70, secured to bed 20, is provided to prevent backward rotation of the
ratchet-disc and connected turn-table. When the machine is in motion, levers 64
are being constantly rocked on their fulcra by the serpentine cam-groove 57 and
the described pawls engage one tooth of the ratchet-discs 58 at each complete
movement of said levers, thus slowly rotating the turn-tables until a quarter-turn
has been completed, when the forward movement of bolt 48 causes its attached
stud 67 to force the longer arm of lever 66 inward. This throws the shorter or
pawl end out of operative engagement with the ratchet-teeth, and for a time said
pawl moves forward and backward idly. When, however, a bobbin-carrier is
moved into the turn-table and bolt 48 pushed outward by it, the pawl is again
allowed to engage the ratchet-teeth and immediately begins to rotate said turn-table
another quarter of a revolution. It will thus be seen that the entering of the
bobbin-carrier in a turn-table acts to throw out the bolt 48, and that such
movement of the bolt allows the pawl to engage the teeth of the ratchet, and that
the constantly-oscillating pawl serves to rotate or partially rotate the turn-table to
allow the bobbin-carrier to depart by the proper channel 34.
The cam-switches 51
also provide automatic means for controlling the arms 38 to cause said arms to take
the bobbin-carriers from the turn-tables or leave them there, as may be necessary,
and it will be obvious that if the several described mechanisms are properly timed
relative to each other certain bobbin-carriers and their threads may be carried
beneath or between other threads at proper times to interlace or braid together
said threads into a single perfect cord.
In Figs. 12, 13, and 14 the general construction of the machine is as above
described; but instead of employing the cam-switches 62 to force inward arms 38
I provide a system of cams, gears, and levers that operate together to draw said
arms inward positively. In this last-named construction I provide a disc 71 in
place of the described disc 39 and slot the same on its under side to receive the
arms 38. I also secure to said disc 71 by studs or screws 72 a series of small
gears 73, that carry with them as they rotate discs 74, having cam-grooves 75.
76 indicates lever-arms having one end connected to arms 38 and the opposite
end connected to the under side of disc 71, while a roll on the side of said lever-
arms enters the cam-grooves 75.
A gear 76 is secured non-rotatably on bed 20 beneath disc 71 and is of such size
that when the several parts are assembled it meshes with the series of smaller
gears 73, which latter as they are carried around by and with disc 71 are caused
to rotate. This rotates the attached cam-discs 74, and through the lever-arms 76
the radial arms 38 are moved outward or inward, according to the shape of the cams.
The central shaft 28 is made tubular, so that a solid core may, if desired, be
introduced into the cord.
The described turn-tables, in addition to turning the bobbin-carriers, as explained
above, also serve a valuable purpose in putting the desired tension into the cord as
it is braided. When the bobbin carrier is moved forward into the turn-table by
arm 38, the thread is left with but little tension; but so soon as the pawl 66 begins
to rotate said turn-table that end of bar 36 over which the tension-screw 46 is
located is gradually carried away from the common centre of the machine, and as a
consequence the thread is gradually strained taut, the peculiar construction (pawl-
and-ratchet mechanism) providing great power and working independently of the
various other parts of the machine.
By providing machines having suitable numbers of turn-tables cord of any
number of ends or threads may be produced, and by varying the time and movement
of the different bobbin-carriers cable-laid and other forms of cord may be made.
Many of the machines now in use for making braided cord have but a limited
range of work. In other words, cord of different sizes cannot be readily made on

page_text: such machines; but with my described machine all of the commercial sizes of such
cord can be produced on a single machine by simply supplying thread or yarn
of suitable size and properly regulating the tension.
Having now particularly described and ascertained the nature of this my said
