1, HARGREAVES BARNES, of No. 197, Blackburn Road, Accrington, in the County
of Lancaster, Mechanic, do hereby declare the nature of this invention to be as
follows:-
--
This invention has reference to warp beaming machines, the object of my improve-
ments being to simplify the parts, and make them more sensitivo when knocking-off
than hitherto.
In carrying out my invention I employ any suitable form of pin box or grate to
receive the suspended pins or weights resting upon the travelling yarn in the ordinary
manner, but underneath the slits in the said pin box I place inclined planes, either
attached to the said pin box and moving on pivots or studs in the framework of the
machine; or the said inclined plane may be separate from the pin box; but in either
case it works upon pivots. The pin box is composed of horizontal bars; and if
made of more than two bars, each bar added 1 make deeper from the top so that
the bottom edge may come close to the inclined plane, so as to cause the extreme
points of the pins or weights to touch the inclined plane and prevent the said
pins or weights from being turned around by the twist that is in the yarn when
through any cause the threads become slack and allow the pins or weights to fall
below the said bars. In combination with the said pin box and inclined plane
I employ a fluted roller, made to revolve on centres in the framework, the said fluted
roller being placed parallel with the inclined plane, and in close proximity to it, so
that if a thread breaks, or a spool is empty, allowing a weight or pin to descend and
pass between the inclined plane and the fluted roller, the effect of which is that the
inclined plane is caused to oscillate on its centre, allowing the fallen pin to pass. To
the inclined plane I fix two knocking off levers connected together by a stay rod,
one of such levers being carried below the inclined plane, and having attached to its
lower end an adjustable catch bracket. The inclined plane is adjusted in its position
with regard to the fluted roller by a set screw or stud placed in the framework of the
machine. When a pin or weight falls and passes between the inclined plane and the
fluted roller, the inclined plane is pushed away from the roller, in doing which
the lever on the end thereof is removed from a hinged segment cam, causing it to
move and operate the connecting rod and a clutch, thereby stopping the rotary motion
of the drum shaft, and simultaneously therewith the rotary motion of the fluted roller
is stopped by throwing out of gear the driving mechanism. The fluted roller I prefer
to drive by means of a strap, cord, or chain, or upright shaft, through the medium of
the friction gearing from the drum shaft, but the said fluted roller may be driven
direct from the drum shaft by any of the above named means, in which case the
V friction pulleys would be dispensed with. The periphery of the hinged segment
(held fast by the knocking off plates so long as there are no broken ends) is slightly
cammed or eccentric, so that when the knocking off plate is operated, allowing the
cammed segment to be set in motion, the cammed part allows the knocking-off plate
to have a little play or lateral movement, permitting a fast or locked pin or weight to
escape or to more freely pass between the fluted roller and the inclined plane. The
flutings or grooves in the roller are slightly rounded on their outer edges, so that when
they meet a pin or weight, the edges of the flutings do not injure the pin. I also
place below the fluted roller a box or holder, removable at pleasure, to receive the
pins as they drop from the pin box. I also stretch upon a rod placed across the
machine the hem of a cloth wiper or clearer, the lower side of which is also hemmed

page_text: to receive another rod which rests on the fluted roller so as to keep it clear of
accumulated fluff or
fly."

Improvements in Warp-beaming Machines.
I, HARGREAVES BARNES, of No. 197, Blackburn Road, Accrington, in the County
of Lancaster, Mechanic, 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:-
This invention has reference to warp beaming machines, the object of my improve-
ments being to simplify the parts, and make them more sensitive than hitherto when
knocking off.
In carrying out my invention, I employ any suitable form of pin box or grate to
receive the suspended pins or weights resting upon the travelling yarn in the ordinary
manner; but underneath the slits in the said pin box [ place inclined planes, either
attached to the said pin box and moving on pivots or studs in the framework of the
machine or the said inclined plane may be separate from the pin box; but in either
case the inclined plane works upon pivots. The pin box is composed of horizontal
bars; and if made of more than two bars, each bar added is made deeper from the
top so that the bottom edge may come close to the inclined plane, in order to cause
the extreme points of the pins or weights to touch the inclined plane and prevent the
said pins or weights from being turned around by the twist that is in the yarn when
through any cause the threads become slack and allow the pins or weights to fall below
the said bars. In combination with the said pin box and inclined plane I employ a
fluted roller, made to revolve on centres in the framework, the said fluted roller being
placed parallel with the inclined plane, and in close proximity to it, so that if a thread
breaks, or a spool is empty, a weight or pin is allowed to descend and pass between
the inclined plane and the fluted roller, the effect of which would be to make the
inclined plane oscillate on its centre, allowing the fallen pin to pass. To the inclined
plane I fix two knocking off levers connected together by a stay rod, one of such
levers being carried below the inclined plane, and having attached to its lower end an
adjustable catch bracket. The inclined plane is adjusted in its position with regard
to the fluted roller by a set screw or stud placed in the framework of the machine.
When a pin or weight falls and passes between the inclined plane and the fluted
roller, the inclined plane is pushed away from the roller, in doing which the lever on
the end thereof is removed from a hinged segment cam, causing it to move and
operate the connecting rod and a clutch, thereby stopping the rotary motion of the
drum shaft, and simultaneously therewith the rotary inotion of the fluted roller is
stopped.
Such being the nature and object of my invention, I will now make reference to
the accompanying sheet of drawings illustrative thereof, wherein
Fig. 1 is end elevation of a warp beaming machine with my improvements applied
thereto,
Fig. 2 part front elevation of same, and
Fig. 3 is enlarged view of some of the improved parts.
A represents the framework of the machine, B the warp beam resting upon the
winding on drum C, fixed upon shaft D, driven by a friction plate within the driving
pulley F, operated by cams or clutches E, in the ordinary manner. The pin box or
grate is shewn at G, and it may be either attached to the framework of the machine
and independent of the oscillating triangular bar H, or the said pin box may form
part of the said triangular bar or be otherwise attached to it as shewn in Fig. 4. In
combination with pin box G and triangular bar H 1 employ a fluted or grooved
serrated revolving roller I driven by chain J from the drum shaft D, so that the said

page_text: fluted roller and drum shaft revolve in unison in one direction. The chain wheel is
placed loosely on the end of the fluted roller, and the latter is driven by means of a
stud e (see Fig. 5) projecting from the side of the chain wheel coming into contact
with another stud or set screw projecting from the end of the fluted roller, so that
when the machine is at work the chain drives the fluted roller, but when it is necessary
to back off or reverse the motion of the machine, the operative turns the flange of the
beam around with his hand, the fluted roller meanwhile remaining stationary, and
when this operation is completed, the operative turns the flange of the beam back
again until the studs e and f come into contact, when the machine is set in motion in
the ordinary way and the chain drives. It will be apparent that the chain wheel
could only move on the axis of the fluted roller, in backing off, until the studs met
from behind, but in order to permit the backing off motion to be increased, I fix on
the shaft D (see detail Fig. 6) a disc D1 carrying a lug D2, and there is also a lug D
projecting from the side of the chain wheel D which is placed loosely on the shaft D,
the arrangement being such that when the machine is at work the disc D' is the
driver, but when backing off, the chain can travel one revolution round the fluted
roller, and if it is necessary to extend the motion, the chain wheel D³ can also make
a revolution, by which means the amount of motion when reversing is extended.
Attached at each end of the triangular bar H are two upright lever arms K,
connected together by a stay rod L, and projecting from one of the lever arms K
is a knocking off lever M carrying at its lower end an adjustable catch N for taking
into a sneck a formed in the hinged segment cam O connected by rod P to the
cammed or clutched surfaces E on the drum shaft D, which parts stop the rotation
of the machine when it is required to knock off. The fluted roller I revolves in close
proximity to the inclined surface of the triangular bar, which is capable of adjustment
by means of set screw b. In order to prevent the edges of the flutings in the roller
fron damaging the pins or weights c when acting against them, the said flutings are
rounded off as shewn in the drawings. In forming the pin box and in combining it
with the triangular bar, it is necessary that the lower edges of the bars in the pin box
should be sufficiently deep to come close to the inclined plane of the bar H, or to
nearly touch it, in order. to prevent the pins or weights being turned around by the
twist in the yarn when the yarn slackens sufficiently to allow the feet of the pins to
descend below the bars forming the pin box.
The action of the machine is as follows:-Pins or weights c are supported by the
travelling yarn in the ordinary manner, but if the yarn is absent, from breakage or
other cause, one of the weights drops through the pin box down the inclined plane,
and when met by the revolving fluted roller, the latter employs the pin as a lever,
forcing it against the triangular bar, which is made to oscillate thereby upon its
pivot d (as shewn in dotted lines) in such a manner as to remove the clutch N from
the sneck a formed in the segment cam O, which on being released is made to partially
revolve and occupy the positions shewn in dotted lines Fig. 3, in doing which the
connecting rod P disengages the cams or clutches E, and simultaneously therewith
the friction plates are brought into action so as to stop any further rotation of the
winding on drum, whereby the machine is stopped. It will be observed that the
periphery of the segment O is eccentric or slightly cammed, so that when set in
motion for the purpose of knocking off, the cammed surface rides against the catch N
so as to cause the knocking off lever to recede and thereby widen the space between
the inclined plane and the fluted roller, permitting a fast or locked pin or weight to
escape and drop into the receiving box Q.
By the arrangement and combination of mechanism as herein described and
illustrated, a reliable and positive self acting stop motion is provided, simple in its
motion and not easily made unworkable.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :—
Firstly. In warp beaming machines, the use in combination of a pin hox or grate G,

page_text: oscillating triangular or other bar H, and revolving fluted roller I, arranged and
combined in manner described and shewn in the drawings.
Secondly. In warp beaming machines, the use of a pin box G, oscillating triangular
or other bar H, revolving fluted roller I, in combination with a knocking off lever M
as described.
Thirdly. In warp beaming machines, the use of a pin box G, oscillating triangular
bar H, revolving fluted roller I, knocking off lever M, in combination with a hinged
segment for knocking off the machine, all as described.
Fourthly. In warp beaming machines, the use of a pin box G, oscillating triangular
bar H, revolving fluted roller 1, knocking off lever M, and hinged segment O for
knocking off the machine, in combination with a cammed surface or eccentric,
for the purpose of removing the triangular bar further from the fluted roller as
described.
Fifthly. In warp beaming machines, the employment of a chain wheel carrying a
stud for driving the fluted roller L, in combination with means for permitting the
machine to be reversed whilst the fluted roller remains stationary, all arranged as
described.
