of "A NEW AND USEFUL IMPROVEMENT IN MECHANISM FOR SPINNING WOOL
OR OTHER FIBROUS MATTERS."-A communication from Robert Loudon

Southbridge, therein.
COMPLETE SPECIFICATION filed by the said John Bapty and Andrew.
Hall at the Office of the Commissioners of Patents, with their.
Petition and Declaration, on the 3rd August 1869, pursuant to the
9th Section of the Patent Law Amendment Act, 1852.
TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME,
we, JOHN BAPTỲ and ANDREW HALL, of the State of Massachusetts, of
the United States of America, do hereby declare the nature of the saiḍ
Invention for "A NEW AND USEFUL IMPROVEMENT IN MECHANISM FOR SPINNING.
WOOL OR OTHER FIBROUS MATTERS," (such Invention being communicated to:
us by Robert Loudon Walker, a Citizen of the said United States, and

page_text: a resident of Southbridge, therein), and the manner in which it is to
be performed, to be fully described as follows, reference being had to
the accompanying Drawings which make part of the Specification of
the said Invention :-
-
'
Of such Drawings Figure 1 denotes an end elevation, Figure 2 a side
view, Figure 3 a top view, Figure 4 a longitudinal section, and Figure 5 a
transverse section of the said improvement and those parts of a spinning
frame with which it is immediately connected and operates; Figure 6
is a longitudinal section of the stationary helical driver of the operative
geer of the draft rollers; Figure 7 is a horizontal section of the said
driver and the draft rollers and their operative gear.
The nature of the Invention consists in the combination, substantially
in manner as herein-after described, of a stationary helix coil or internal
screw thread with the geer of the draft rollers provided with mechanism
for revolving them, for the purpose of putting twist into the yarn or
sliver, such helix coil or thread being to revolve the said geer, in order
to turn the draft rollers in a manner to cause them to draw out or
lengthen that part of the sliver which may be between them and the
delivery rollers of the machine. The helix coil and its case or hollow
cylinder from whose internal surface the coil projects may be termed
the helical driver.
In the Drawings A denotes the frame of a ring and traveller spinning
machine, a being a ring, 6 the ring rail, and c a spindle, the latter being
provided with a bobbin d, and also with a whirl e. An endless band f goes
around the said whirl and a driving drum g. Above the latter is another
drum h, around which and a grooved pulley i fixed on the lower end of
the lower neck 1 of a rotary draft roller carrier B another endless band a¹
extends. The said carrier, as formed, has the shape of a rectangular box,
open on two opposite sides, it being provided with tubular necks k, l,
extending from it vertically. These necks are journals which extend
through corresponding bearings made in the two support bars or rails C, D,
arranged in the frame A in manner as represented. There is a pair of
geered draft rollers m, n, arranged within the carrier B with their axes
horizontal, there being fixed on the shaft or one journal of one of the
said draft rollers a geer o. Surrounding the said carrier and-geer is
the helical driver, which consists of a cylindrical case-
and a screw
thread q or coil formed on its internal curved surface. The said thread
engages with the teeth of the geer o. The case p of the driver extends

page_text: down from the rail C, and is supported on and by the rail D, the upper
of the two rails being held to the lower of them by screws r, r, which
go down through the upper and screw into the lower of the said rails.
When the carrier is in revolution the geer o will be slowly revolved
by the helical thread q, and consequently will revolve one draw roller
on its axis; the other draw roller by engaging with the first will
be simultaneously revolved by it. Above the carrier is a set of delivery
rollers 8, 8, between which the sliver from a bobbin or beam is led.
The sliver or roving to be drawn and twisted is first wound on the
said beam. The roll of sliver or roving rests on another beam or
roller arranged in manner as represented. There is a driving pulley
or wheel a, and two grooved pulleys y, z, fixed on the shaft of the
drum . An endless band 'goes around the pulley y and a pulley z
fixed on the shaft of the lower drum g. Furthermore another endless
band c goes around the pulley z and a pulley ' fixed on the shaft of
the roller v. On the latter shaft is a grooved pulley d', about which
and another pulley e fixed on the shaft of the lower delivery roller an
endless band f¹ runs. When the driving pulley is put in revolution
motion will be communicated to the several operative parts of the
machine. The sliver is to be led from its beam to and between the
delivery rollers, and from thence into the upper neck of the draft roller
carrier, thence down between the draft rollers, thence through the lower
neck of the said carrier, thence through the traveller, and finally to
the spindle or the bobbin thereon. The carrier being in revolution will
twist that part of the sliver or roving which is between the draft rollers
and the delivery rollers. The draft rollers at the same time will slowly
draw out the sliver or roving and deliver it to the spindle or bobbin
revolved thereby. The helical driver for operating the geer of the draft
rollers is a very simple and effective means of producing the effect, as
by it a very slow revolution of the geer results; when the rollers are
revolving, in effecting the twist of the sliver. The spindle removes the
counter twist of the roving and puts in the extra twist necessary.
With the common mule or jack employed to spin wool of very short
staple from eight to twelve feet of yarn per spindle per minute is the
amount usually produced, but with a machine constructed substantially,
as herein-before described and provided with the improvement thirty-six.
to fifty feet per minute of yarn may be spun with ease and safety from
very short wool.

page_text: What is herein claimed as the improvement in question is, the
arrangement or combination, substantially in the manner described, of
the helical driver or helix coil with the geer of the draft rollers pro-
vided with mechanism for revolving them, so as to effect the twisting of
the sliver or roving, as specified.
