COMPLETE SPECIFICATION (AMENDED).
Improvements in and relating to Machines for Inserting Wire Coils
into Leather or Fabrics.
We, HENRY MOYER JACKSON and GEORGE MILTON JACKSON, machinists, residing
respectively at No. 2321 Mole Street, in the City and county of Philadelphia, and
No. 1226 Chestnut Street, in the City of Reading, County of Berks and State of
Pennsylvania, United States of America, do hereby declare the nature of this in-
vention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to wire coils and improvements in machines in which
said coils are inserted into leather belts or fabrics, the two ends of which are to be
joined by means of said coils.
In the machines heretofore in use it has been necessary to have a right hand
coil in one end and a left hand coil in the other end of the belt in order that they
would mesh properly when brought together to be joined.
By means of our improved machine we can use either two right hand coils or
two left hand coils or one of each, for after the coils are flattened out on our
machine, flush with the surface of the belt, the convolutions of the coils will be
perfectly straight and at right angles to the axis of the coil, the pitch of the wire
between two convolutions being forced to the point where they pass through the
belt; this will allow the two coils to mesh properly no matter whether they have
been wound right or left as the pitch of each convolution is entirely removed from
that portion thereof which projects beyond the edge of the belt.
By reason of the fact that either a right or left hand coil can be used on both
ends of the belt it is evident that both ends can be placed in the machine and the
coils inserted into them at one operation instead of two operations in different
directions as required when a right and left hand coil is used which requires a
reversible machine or two machines.

page_text: The rolls A, B and C in our machine are placed in the usual position and the
jaws D and E as usual are located just in front of them.
The rolls are mounted in ears F, one on each end of the machine, which ears
are pivotally secured to the lower jaw as shown in Figure 3.
The rolls are formed at their feed ends with a slight taper so that when the
coil is entered, it will find its way between the rolls without difficulty.
The lower roll C is provided with a circumferentially projecting ring el, a short
distance from the feed end and is so located that the end of the coil being fed will
enter the material immediately after leaving the groove next to said ring as the
guide G will be so placed as to bring the edge of the belt on line with the said
groove and as the coil always enters the material directly off of the lower roll it
will be seen that it is impossible for the coil to bend or be forced out of its true
path, which is due to the fact of the belt being located immediately alongside of
said ring.
The rolls B and C, i.e.-the rear and lower rolls are grooved longitudinally near
the outlet end thereof for about one third of their circumference and the length of
an ordinary needle such as is used on this class of machines; the rolls are so set
that these grooves 62 and 2 will register at every revolution of the rolls.
The object of these grooves is that when it is desired to feed a coil of wire into a
belt, it is customary to first pass through said belt a coiled needle so that the per-
forations will be ready to receive the coil when entered. When this needle has
passed through the machine and reaches that portion of the rolls where they are
grooved, it will drop out of the machine automatically and can be caught in any
suitable receptacle provided for that purpose.
When it is desired to join two ends of leather it is not necessary in all cases to
insert a coil into each end and then join them for the two ends can be placed
between the jaws at the same time, one above the other, and a single coil entered
into them; then the jaws are opened and the cars F which carry the rolls are
thrown down to the position shown by dotted lines in Figure 3 and the one end
of the belt is passed between the jaws bringing the coil in position to be flattened.
Each roll in the machine is backed by a strengthening rib a, b and c and the
space between the roll and the rib is filled with babbit or other soft metal thus
giving it a bearing the whole of its length; the rolls are mounted eccentrically in
projections q on these ribs (See Figure 6) so as to give the proper movement when
adjusted.
In the rib backing the outer roll B, we provide a slot 6' in which is located a
vertical block L through which passes a screw S; to the ends of this block are
pivotally secured links and ¹ connecting respectively the ribs a and c of the
rolls A and C.
On the end of the screw S is provided a thumb piece by means of which the
screw is turned thus moving the block L forward or backward in the slot b¹ and
drawing the rolls A and C nearer to or farther away from the roll B.
This adjustment is desirable when different sizes of coils are used or when there.
is not sufficient friction to cause the coil to feed properly.
The jaws D and E are opened and closed by means of a lever H¹ secured to the
eccentrically mounted shaft H. This shaft bears in a semi-circular groove along
the top of the upper jaw and its eccentric ends are mounted in bearings h on either
end of said jaw.
The
On the ends of both jaws are provided lugs m in which are secured bolts n.
bolts screw into the lugs on the upper jaw and pass through the lugs of the lower 5
jaw and are provided at their lower ends with nuts. There is also a guide lug o
pivoted to each end of the upper jaw through which these bolts pass.
By a half revolution of the shaft H the jaws are opened or closed and the bolts n
keep the jaws perfectly parallel.
These jaws are formed with serrations t on their meeting faces nearly their full 5
length and about half of their width; the other half of the faces is flat. With
this construction the coils can be pressed first between the serrated portions,

page_text: forcing the convolution into the proper angle, and then between the flat portions
and pressed into the belt making the surfaces perfectly flush.
A guide G is placed near the feed end of the lower jaw. This guide is so
situated that when the belt is placed in the machine against it, the coil will enter
the edge of said belt immediately on leaving the ring c¹ and when the belt is
pulled forward, bringing the coil between the jaws, by keeping the belt against the
guide, the serrations of the jaws will be sure to engage the convolutions of the coils
properly and not allow them to be forced out of line, and at the same time it will
insure the coil being inserted into the end of the belt at right angles to its length.
It is evident that the serrations can be made V-shaped if desired, as the form is
not essential and can be varied to suit circumstances.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
1. A wire coil machine having top and bottom jaws adapted to engage the coil
and having serrations formed on a portion of their meeting faces, rolls mounted in
swinging ears, backed by strengthening ribs and adapted to feed said coil through
a belt or other article, substantially as set forth.
2. A wire coil machine having top and bottom jaws adapted to engage and
flatten the coil, adjustable rolls mounted in swinging ears pivotally connected to
the lower jaw, said rolls being adjustable by means of a movable block and links
located back of each roll and operated by a screw, substantially as set forth.
3. A wire coil machine having top and bottom jaws adapted to engage and
flatten the coil, adjustable rolls tapered at their feed ends and mounted in swing-
ing ears pivotally secured to the lower jaw, one of said rolls provided with a cir-
cumferentially projecting ring near its feed end and the rear and lower rolls being
formed with registering grooves near the outlet end thereof, substantially as set
forth.
4. A wire coil machine having top and bottom jaws adapted to engage and
flatten the coil, said top jaw having upwardly projecting ears in which is
eccentrically mounted a shaft H, guide rods n secured in lugs on the ends of said
jaws and adapted to travel in pivoted guides o, the upper jaw being operated by
means of a lever secured to the shaft H, and the lower jaw being provided with
a guide G for the belt or other article, substantially as set forth.
