PROVISIONAL SPECIFICATION.
Improvements relating to the Building Motions of Roving Frames.
We, JAMES BARBOUR and ABRAM COMBE, of the Firm of Combe, Barbour, and
Combe Limited, of Falls Foundry, Belfast, Ireland, Machinists, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in reversing motions for reversing
the traverse of the "builder" in roving frames, the object being to ensure the
instantaneous reversal of the motion at the correct time, i.e., when the pin on the
"builder" which carries the bobbins operates the bell-crank lever which controls
the reversing motion. The invention consists of an arrangement and combination
of parts constituting improved mechanism which positively controls and actuates
the two pinions, one or other of which drives the wheel for communicating motion
to the builder, and such mechanism also securely holds the then operating pinion
in gear with the wheel, so that the driving is continuous and certain.
According to this invention we employ the ordinary bell-crank lever operated
by the pins on the builder which carries the bobbins, and to an arm of this bell-
crank lever is attached a link, the other end of which is connected to a swinging
or pendant forked lever mounted on a stud fixed to the end frame of the machine.
Inside the fork of the lever is a heart or V shaped "smoothing iron" mounted in
such lever, and forced in an outward direction by means of a spiral spring. The
heart or V shaped "smoothing iron" rests on a corresponding iron" formed on
the end of a short lever which carries the two reversing pinions, such lever being
elongated at its lower end, and the outer ends of the forked lever extend as far as
the elongated end of the lever, and are provided with adjusting screws which come
into contact with said lever.
The action is as follows:-When one of the pins on the builder meets the end
of the bell-crank lever, the latter is raised, and the link causes the forked lever to
swing on its studs, and the heart shaped smoothing iron is moved up to and over
the point of the corresponding smoothing iron, the spiral spring of the former
being compressed. Just previous to the point of the first smoothing iron reaching
the point of the second one, the adjusting screw on one of the forks of the lever
comes into contact with the elongated pinion lever, and the smoothing iron and
the forked lever simultaneously and instantaneously throw over the pinion lever
on its stud, and bring the alternate pinion into gear with the wheel which
communicates motion to the builder..
The action of the apparatus is the same whether the builder is rising or falling.
By the improvements hereinbefore described, the driving or reversing pinions
are instantaneously changed, and when changed are securely locked in position
so that the driving is continuous, one of the pinions being always held in gear by
the pressure of the spiral spring acting on the heart or V shaped "smoothing
iron."

We, JAMES BARBOUR and ABRAM COMBE, of the Firm of Combe, Barbour, and
Combe, Limited, of Falls Foundry, Belfast, Ireland, Machinists, 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 relates to improvements in reversing motions for reversing
the traverse of the builder" in roving frames, the object being ip ensure the
instantaneous reversal of the motion at the correct time, i.e, when the pin on the
builder" which carries the bobbins operates the bell-crank lever which controls
the reversing motion. The invention consists of an arrangement and combination
of parts constituting improved mechanism which positively controls and actuates
the two pinions, one or other of which drives the wheel for communicating
fing motion
to the builder, and such mechanism also securely holds the then operating pinion
in gear with the wheel, so that the driving is continuous and certain.
Such being the nature and object of our said invention, the following is a com-
plete description of same, reference being had to the accompanying drawing which
is an elevation, partly in section, of so much of a roving frame as is necessary to
illustrate our invention.
"
According to this invention we employ the ordinary bell-crank lever 1 mounted
on a stud 1" and operated by the pins 2, 3 on the builder 4 which carries the
Bobbins as ordinary. To an arm of the bell-crank lever 1 is attached a link or
connecting rod 5, the other end of which is connected to a swinging or pendant
fork lever 6 mounted and free to rock, on a stud 7 fixed to the end frame of the
machine. Inside the fork of the lever 6 is a heart or
or V shaped smoothing
iron" 8 mounted in such lever 6 and forced in an outward direction by means of
a spiral spring 9. The heart or V shaped smoothing iron 'S rests on a cor-
responding iron 10 formed on the end of a short lever 11 which carries the two
reversing and driving pinions 12, 13, such lever 11 being elongated at it's
its Tower
end 14, and the outer ends of the forked lever 6 extend as
the elongated
end 14 of the lever 11 and are provided with adjusting screws 15, 15 which come
into contact with the end 14 of the said lever 11, and if the spring 9 fails to act,
the pinions 12 or 13 are by one of such screws forced out of gear with the wheel 18,
thus ensuring a positive withdrawal motion.

In the drawing the pinion 12 is shewn in gear with the wheel 18 which com-
municates motion through the rack wheel 18 and builder rack 19 to the builder 4,
and the pinion 13 is shewn out of gear with the wheel 18. The pinions 12, 13,
are driven in the ordinary manner, the wheel 12 being keyed on the traverse
shaft.
The action is as follows:-When a say the lower pin 3 of the pins 2, 3 on the
builder 4 meets the end of the bell-crank lever 1, the latter is raised and the link 5
causes the forked lever G to swing on its studs 7, and the heart shaped smoothing
iron 8 is moved up to the point of the corresponding smoothing iron 10, the spiral
spring 9 of the former being compressed. Just previous to the point of the first
smoothing iron 8 reaching the point of the second one 10, the adjusting screw 15
on one of the forks of the lever 6 comes into contact with the elongated end '14
of the pinion lever 11, and the smoothing iron 8 and the forked lever. 6 simul-
taneously and instantaneously throw over the pinion lever 11 on its stud 17, and
thus brings the alternate pinion 13 into gear with the wheel 18 which com-
municates motion to the builder 4. When the pinion 13 is in gear with the

page_text: wheel 18 the traverse shaft is bent a little out of line, the distance of the first
bearing allowing for this. Wheel 18 carries a pinion 20 gearing with the internal
wheel 21 on the rack shaft 22 on which is the wheel 18 gearing with the rack 19.
The action of the apparatus is the same whether the builder 4 is rising or falling.
By the improvements hereinbefore described the driving or reversing
pinions 12, 13 are instantaneously changed, and when changed are securely locked
in position so that the driving is continuous, one of the pinions being always held
in gear by the pressure of the spiral spring 9 acting on the heart or V shaped
smoothing iron 8.
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:
(1). The general construction, arrangement, and combination of parts constitut-
ing the improved reversing motion of roving frames as and for the purpose
herein described and substantially as illustrated by the annexed drawing.
(2). The swinging forked lever G, spring mounted heart shaped smoothing iron 8
and iron 10 forming part of the lever 11 and carrying, the pinions 12, 13 all in
combination as and for the purpose herein described and substantially as illustrated
by the annexed drawing.
(3). The swinging forked lever 6, spring mounted heart shaped iron 8, and
adjusting set screws 15, 15 all in combination as herein described and substantially,
as illustrated by the accompanying drawing.
