Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We EDWARD SAMUEL BOND of The Crown Engine and Machine Works Lower
Hurst Street East Birmingham in the County of Warwick Engineer and Machinist
and SAMUEL WILLIAM JOHNSON of Clifton Road, Aston near Birmingham aforesaid
Machinist, do hereby declare the nature of our invention for AN IMPROVED
AUTOMATIC REVERSING TRAVERSE MOTION FOR BOBBIN WINDING AND OTHER
MACHINES, to be as follows:-
Our Invention relates to and consists of Improvements by means of an Automatic
gearing or screw and clutch reversing motion in Bobbin Winding Machines. These
Machines are used for winding the Bobbins for the use of Wire Netting Machines.
The ordinary Bobbin Winding Machines now employed use only one or two
Bobbins, and they require the constant services of a man or boy in the working of
the Machine. Our Improved Bobbin Winding Machines will use four or more
Bobbins simultaneously and do not require constant personal attention, being, when
set in motion, self acting, thus effecting a great saving in labour-wages and at tho
same time doing four times (or more according to the number of Bobbins used,) the
amount of work of the ordinary Machines.
In order that our said Invention may be properly understood we have hereto
appended a sheet of explanatory Drawings. In these Drawings Figure 1. is a front
elevation of the Machine. A is a reversing clutch having two screw jaws and a
notch A' on it This clutch traverses an upper screw B passing under a spring C
until it reaches the slot D when it falls through and traverses the lower screw B'
passing on the upper side of the spring C until it reaches the slot D' when the
same motion is repeated. The clutch A gives motion to a plate E by means of a
vertical rod connected to a horizontal rod. The Wire is passed round pulleys
fastened to the front of this plate, which, as it moves slowly with the reversing
clutch winds the wire on the Bobbins in an even and thread like form and
of uniform increasing diameter, and by its instantaneous action prevents the
running Wires from making too many coils on the bobbins at either ends, the
Bobbins being wound from end to end perfectly even and smooth. Plate F is
a guide for the clutch A as it traverses the upper and lower screws B and B.

of gear with the screws B and B' when required.
Figure 2 shews the reversing clutch A.
Figure 3 is a plan of the Machine.
Figure 4 is a side and front elevation of plate E.
We do not confine ourselves to claiming this Automatic gearing or screw and
clutch reversing motion as applicable to Bobbin Winding Machines only, but we
claim it as applicable also to a variety of other Machines and whero ever such
motion could be usefully or beneficially employed.

described and ascertained in and by the following statement:-
Our Invention relates to and consists of Improvements by means of an Automatic

Machines are used for winding the Bobbins for the use of Wire Netting Machines.
The ordinary Bobbin Winding Machines now employed use only one or two
Bobbins, and they 'require the constant services of a man or boy in the working of
the Machine. Our Improved Bobbin Winding Machines will use 4, or more
Bobbins simultaneously and do not require constant personal attention, being when
set in motion, self acting, thus effecting a great saving in labour and wages and at

the amount of work of the ordinary Machines. In order that our said Invention
may be properly understood we have hereto appended a sheet of explanatory
Drawings.
"J
In the Drawings Figure 1, is a front elevation of the Machine, "a is a reversing
clutch having two screw Jaws and a notch or projection "a" on it. This clutch
traverses an upper screw "b" passing under a spring "c" until it reaches the
slot "d" when it falls through and traverses the lower screw "b" passing on the
upper side of the spring "c" until it reaches the slot "d" when the same motion
is repeated. The clutch "a" gives motion to a plate "e" by means of a vertical
rod connected to a horizontal rod. Tho wire is passed round pulleys fastened to
the front of this plate which as it moves slowly with the reversing clutch winds
the wire on the Bobbins in an even and thread like form and of uniform increasing
diameter. And by its instantaneous action prevents the running wires from
'making too many coils on the Bobbins at either end, the Bobbins being wound
from end to end perfectly even and smooth.
Fig. 2. shews the reversing clutch "a."
Figure 3 is a plan of the Machine.
Figure 4. is a side and front elevation of plate "e."
We do not confine ourselves to claiming this Automatic gearing or screw and
clutch reversing motion as applicable to Bobbin winding Machines only but we
claim it as applicable also to a variety of other Machines, and where ever such
motion could be usefully or beneficially employed.
And in order that this our said Invention may be more clearly understood wo
have introduced on the sheet of Drawings some other figures which in combination
with the foregoing. figures we will now proceed to describe. Similar letters of

page_text: Figure 5, is a plan and elevation of the slotted plate "f" with cover
plates "g g."
Figure 6, is an end view of the Machine complete.
Figure 7, is a side elevation of the slotted plato "f" with its springs and cover
plates.
Figure 8, is a plan and elevation of the springs "o" and "c¹."
Figure 9; shows part of plate "ƒ" with a slot covered by plate "g."
"
All the working parts of the Machine are carried by a base plate "h" on the
underside of which are cast or otherwise secured projections "1" for carrying the
horizontal rods "8" on the upper side of the base plate "h are secured two
standards "J" "J" those standards are provided with suitable bearings in which
rotate the ends of the screws "6" and "b" On this same base plate "h" are also
secured four standards "k" provided with suitable bearings in which rotate the
spindles " and " On the spindle "" are secured fast and loose pulleys "m, m"
for giving motion to the Machine. On one extreme end of the upper screw "b." is
a spur wheel "n" which gears into two spur pinions "n, n¹" which are secured to
the spindles " and " respectively. These pinions "n, n¹" are equal in size. On
the other extreme ends of the screws "b and 61" are fixed equal size spur
wheels "O, O¹" gearing into each other. By this arrangement it will be seen that
the two screws b and b¹" revolve at the same speed as each other but in opposite
directions and that the spindles " and " revolve at the same speed and in the
same direction as each other and at a considerably greater velocity than the
screws "b and b¹" The pitch of the screws "b and 6" is such that in combination
with the wheels "n and n¹" and "n" a suitable longitudinal motion is given to
the guide plates "e" and thence to the wires "q" coming from the coils "q" so
that they are wound evenly on the Bobbins at "q" These Bobbins "p" are each
carried on a turned down portion "" of the spindles " and " to which they are
temporarily secured by the nuts "3" on the screwed parts at the extreme ends of
the spindles. The clutch "a" is attached by its pivot "a" to a vertical rod "*"
which is firmly fixed at its lower end to one of the horizontal rods "&" at or about
the middle of the length of the horizontal rod. These horizontal rods "&" slide
through holes in the projections "h" on the bed plate and are secured at their
ends to the guide plates
" 8, e by means of the screws "81, 8" The slotted
plate "f" with its springs and cover plates is secured to the standards "J" in a
position parallel to the screws "b and b¹" The cover plates "g" pivotted at "g¹"
to the fixed slotted plate "f" may each be thrown across the slot "d or d'" when
it is desired to throw the clutch "a" out of gear as shewn in Figure 6. The
action of the Machine is as follows, the wires "q" are led from the coils "q"" over
and under the grooved guide pulleys "e" and the plain guide pulleys "" on the
guide plates "e" to their respective Bobbins "p" which have been temporarily
attached to the Spindles, " and " At this time the clutch "a" and by con-
sequence the guide plates "e" are in one of their extreme positions either to the
right or to to the left. We will suppose to the right looking at Figure I. The cover
plates "g" on the fixed slotted plate "f" being withdrawn from their respective
slots the clutch "a" has its screwed portion "a" in gear with the screw "b"
motion now being given to the Machine the wires "9" are simultaneously wound
on all the Bobbins and at the same time the guide plates "e" travel slowly to the
left being controlled by the partial nut "a³" on the clutch "a" gearing with the
screw "b." The projection "a" moves along the top of the slotted plate "f" and
800n it comes into contact with the spring "c" under which it moves forcing the
end of it up. When the projection "a" reaches the slot "d" it is forced through
it by the elasticity of the spring "c." The clutch "a" then partly rotating on its
pivot "a" the screwed Jaw "a" falls in gear with the screw" 6" which is moving
in the reverse direction to "b" this causes the instantaneous reversal of the motion
and movement of the clutch "a" the rods " and 8" and the guide plates "e" with
their pulleys and by consequence the wires "q" to the right at the same speed at
which they had previously travelled to the left thus winding a second coil of wire

page_text: over the first. The reversing action thus described takes place alternately at each
end of the Machine until a sufficient quantity of wire has been wound.
In Figures 1 and 3 the Machine is drawn as it would appear after a small part
of the first coil on each Bobbin has been wound going towards the left.
Should it be desired to put the clutch "a" out of gear the cover plates "g" are
pushed across the slots to which they belong as shown in Figure 6 and Figure 9.
the springs "c and c" are then provented from pushing the projection "a1"
through the slots in the plate "f"
We do not limit ourselves to the exact shape or configuration of parts shewn on
the Drawing and described in the Specification but we may vary the same while.
not departing from the main features of our said Invention.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed-We declare that
what we claim is
First. The combination of two screws with a screwed clutch capable of gearing
with either which clutch is automatically thrown in gear with either screw by
means of two springs one on each side of a slotted plate fixed to the Machine. The
throwing in gear of the clutch causing the reversal of its motion as described
berein before and shewn on the Drawing.
Second. The application of the reversing motion thus obtained to the even
coiling of Wire on Bobbins by means as described.
Third. The general construction and combination of parts as described in this
Specification, and shewn on the accompanying sheet of Drawings for a Machine for
winding Wire on Bobbins preferably four in number for use in a Wire Netting
making Machine.
Fourth. The application of an instantaneous reversing motion as herein before
described to Machines where such a motion is required other than Wire Bobbin
Winding Machines.
