Improvements in Machines for Making Travellers for the Rings of
Ring Spinning and Doubling Frames.
I, HENRY TETLOw, of Varley Street, Miles Platting, Manchester, in the County
of Lancaster, Heald and Wire Manufacturer, do hereby declare the nature of
this invention to be as follows:-
My said invention relates to the machines used for making ring travellers.
In such machines at present used the wire is fed forward against a fixed
abutment, cut into lengths, and bent to the required shape. It is found in prac-
tice that the method of feeding the wire is defective as it frequently happens
that too much or too little is fed forward so that the length cut off varies, caus-
ing defective travellers which have afterwards to be sorted out.
My improvements consist chiefly in the provision of means whereby a definite
length of wire may be fed to the machine, and by means of which such length
of wire is positively and accurately adjusted to the length required before the
wire is cut and bent.
To feed forward the length of wire I provide a pair of feed rollers. One of
these rollers is mounted in fixed bearings and is driven by bevel or other suit-
able gearing from the driving shaft of the machine. The other roller is mounted
in sliding bearings and is thrust into contact with the roller in fixed bearings
by means of a spring or the like. The roller in sliding bearings is positively
driven from the other roller by means of pinions. The roller in loose bearings
is composite and is formed of two parts. The lower portion is a disc with a
portion of its periphery flattened. The length of this flattened portion indicates
the maximum length of wire capable of being fed to the machine in one revolu-
tion of the rollers. The upper portion is also a disc with a flattened portion.
The superimposed disc can be readily revolved on its axis by slackening a nut.
The wire passes to the guide of the machine between the roller in fixed bear-
ings and the lower portion of the loose roller. By revolving the upper disc
so as to allow its concentric periphery to protrude beyond the flattened surface
on the lower disc, the protruding concentric periphery coming into contact with
the roller in fixed bearings removes the lower disc from contact therewith and
the frictional grip on the wire is released. The two discs form as it were a
double adjustable cam, the lower eam at times coming into contact with the
other roller and feeding forward the wire, and the upper cam coming into
action to remove the lower cam and release the wire. By revolving the upper
disc relatively to the cam surface on the lower, the upper cam can be brought
into action sooner or later as required so that any length of wire from a maximum
to a minimum can be readily fed to the machine.
Instead of bringing the wire fed to the machine into contact with an adjust-
able fixed abutment before it is cut as is at present the practice, I mount the
adjustable abutment to slide and reciprocate the same by means of a pivotted

page_text: lever actuated by means of a cam mounted on the driving shaft.
Any other
suitable means for reciprocating the sliding abutment may however be adopted.
I prefer to arrange the feed rollers so that they feed forward wire a triffe in
excess of the length required.
The reciprocating abutment adjusted so that at the end of its forward stroke
it will form a stop to limit the length of wire required. The wire is fed to the
machine by the feed rollers and released from the rollers as described. The
reciprocating abutment on its forward stroke comes into contact with the end
of the wire and, if the wire is a little in excess as described, retracts it, so that
an accurate length of wire is cut, and bent to the required form. The cutting
and bending mechanism are as before and form no part of my invention.
It will be obvious that by my improved arrangement for feeding and regulat-
ing the wire into predetermined definite lengths before the same is cut and bent,
that travellers can be made with absolute regularity and certainty.
Instead of pulling the wire from the reel by the action of feeding forward the
wire as is at present the practice I drive the reel by a suitable slow motion so
that jerking of the reel is avoided. To effect this I may provide the shaft from
which the feed rollers are driven with a worm gearing with a worm wheel
mounted on a short shaft.
This short shaft is provided with a grooved pulley connected by a band to
another grooved pulley mounted on the axis of the reel which is carried by suit-
able standards secured to the frame of the apparatus.
The pullies can be formed with differential grooves or they may be changed
to provide for the variable driving of the reel.

Improvements in Machines for Making Travellers for the Rings of
Ring Spinning and Doubling Frames.
I, HENRY TETLOW, of Varley Street, Miles Platting, Manchester, in the County
of Lancaster, Heald and Wire Manufacturer, do hereby declare the nature of
this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by. the following statement and accompanying
drawings:-
-
My said invention relates to the machines used for making travellers for ring
and doubling frames.
In such machines at present used the wire is fed forward against a fixed
adjustable abutment, cut into lengths, and bent to the required shape. It is
found in practice that the method of feeding the wire is defective as it frequently
happens that too much or too little is fed forward so that the length cut off
varies causing defective travellers which have afterwards to be sorted out.
My improvements consist chiefly in the provision of means whereby a definite
length of wire may be fed to the machine, and by means of which such length
of wire is positively and accurately adjusted to the length required before the
wire is cut and bent.
The accompanying sheet of drawings clearly illustrates my invention.
Fig. 1 is a plan view of a machine for making ring travellers, only so much
being shown as is necessary to illustrate my invention.

page_text: Fig. 2 is a sectional elevation of the same.
The remaining figs. are detail views.
To feed forward the length of wire I provide a pair of feed rollers a b. One
of these rollers a is mounted in fixed bearings c c and is driven by bevel gearing
from the driving shaft of the machine as follows.
As shown in Fig. 2 of the drawings the driving shaft is provided with a
bevel pinion e gearing with another bevel pinion e¹ carried upon a vertical
shaft mounted to revolve in bearings in the frame of the machine.
The lower end of the shaft f also carries a bevel pinion f¹ which gears with a
pinion mounted on a countershaft h which is thus driven. A bevel pinion h
on the countershaft meshes with a pinion on the shaft to which is secured
the fixed roller a. The shaft 3 of the other roller bis mounted in a block b¹
sliding in a bracket ; secured to the frame and is thrust into contact with the
roller a by means of a spring j regulated by a screw or the like as will be
more apparent from an inspection of Fig. 4 in which the rollers are removed.
The roller bin sliding bearings is positively driven from the other roller
by means of pinions. The roller 6 in loose bearings is composite and is
formed of two parts.
The lower portion 62 of the roller is formed of a disc with a portion of its
periphery flattened. This disc is shown in plan and elevation respectively in
Figs. 5 and 5. The upper portion also shown separately in Figs. 6 and 6"
is also formed with a corresponding flattened periphery and formed with a reduced
concentric portion 6 for the greater portion of its thickness as will be apparent
from an inspection of the enlarged views Figs. 5 to 8. The wire passes to the
guide of the machine between the roller a and the lower or middle portion
of roller band is fed forward by the frictional grip of the roller a and reduced
concentric portion of the roller b. The position of the two rollers when feed-
ing wire is shown in the sectional view Fig. 5 and in the plan view Fig. 7 the
reduced diameter of the roller being then in contact with the wire.
As the feed rollers revolve the flattened or cam surfaces formed on the roller b
and disc come into contact with the roller a and remove the reduced diameter b
of the roller from contact with the wire marked z the feed of which is thus
stopped. This is shown in Figs. 16, and S.
As shown in the plan view Fig. 7 the cam surfaces on the upper disc b and
the lower b coincide and the maximum feed of the rollers is thus effected. By
slackening the nut confining the roller to its shaft 63 the upper portion may be
revolved as shown in Fig. 8 so as to bring the cam surfaces on the lower disc ³
more or less early into action as required so that any length of wire from a
maximum to a minimum can be readily fed to the machine.
Instead of bringing the wire fed to the machine into contact with an adjust-
able fixed abutment before it is cut as is at present the practice, I mount the
adjustable abutment to slide on ways cut or formed in the bed of the
machine and reciprocate the same by means of a lever m pivotted at m¹ and
actuated by means of a cam n mounted on the driving shaft. This arrangement
is clearly shown in Figs. and 1*. A spring n maintains the bowl o of the
lever m in contact with the cam n.
I prefer to arrange the feed rollers a b so that they feed forward wire a trifle
in excess of the length required.
The reciprocating abutment is adjusted so that at the end of its forward
stroke it will form a stop to limit the length of wire required. The wire is
fed to the machine by the feed rollers a band released from the rollers as
described. The reciprocating abutment on its forward stroke comes into con-
tact with the end of the wire and, if the length of wire is a little in excess as
described, retracts it, so that an accurate length of wire is cut, and is then bent
to the required form. The cutting and bending mechanism are as before and
form no part of my invention.
It will be obvious that with my improved arrangement for feeding and regu-

page_text: lating the wire into predetermined definite lengths before the same is cut and
bent that travellers can be made with absolute regularity and certainty.
Instead of pulling the wire from the drum or reel by the action of feeding
forward the wire as is at present the practice I drive the reel by a suitable slow
motion so that jerking of the reel is avoided. To effect this I provide the shaft h
from which the feed rollers are driven with a worm gearing with a worm
wheel mounted on a short shaft q as shown in Figs. 2 and 3.
Fig. 3 shows the arrangement in plan view.
This short shaft is mounted in bearings in a bracket r bolted to the frame of
the machine and is provided with a grooved differential pulleys connected by
a band to a grooved differential pulley t mounted on the axis of the reel u
which is carried in suitable bearings formed in a bracket carried by a stan-
dard secured to the frame of the apparatus. A tension nut and spring
are employed to jamb the reel u to some extent against its bearings so as to
prevent it from overrunning.
Instead of differential pullies grooved change wheels may be employed to
provide for the variable driving of the reel. By these means the wire reel or
drum may be slowly revolved so as to deliver and feed the wire to the machine
exactly as it is required.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
1) The improved mechanism for feeding forward and adjusting the wire in
machines for making travellers for ring spinning and doubling frames con-
structed arranged and acting in the manner and substantially as described and
shown.
2) In machines of the indicated nature the revolving feed rollers ab one of
which is carried in sliding bearings and is formed as an adjustable cam to regu-
late the length of wire fed to the machine in each revolution of the rollers in
the manner and substantially as described and illustrated.
3) As means for adjusting the length of wire fed to machines for making
travellers for ring spinning and doubling frames, mounting the adjustable
abutment to slide and reciprocating the same by means of a pivotted lever
actuated by a cam from the driving shaft substantially as described and illustrated.
4) Driving the wire drum or reel in machines of the indicated nature to feed
the wire to the machine in the manner and substantially as described and shown.
