IMPROVEMENTS IN ROVING FRAMES AND OTHER MACHINES FOR PREPARING COTTON AND OTHER FIBRE
Year: 1881

page_text: LETTERS PATENT to John Cryer, of Dukinfield, in the County of Chester,
Machine Maker, for an Invention of "IMPROVEMENTS IN ROVING FRAMES
AND OTHER MACHINES FOR PREPARING COTTON AND OTHER FIBRE."
PROVISIONAL SPECIFICATION left by the said John Cryer at the Office
of the Commissioners of Patents on the 15th December 1881.
JOHN CRYER of Dukinfield, in the. County of Chester Machine Maker.
"IMPROVEMENTS IN ROVING FRAMES AND OTHER MACHINES FOR PREPARING
COTTON AND OTHER FIBRE."
The object of my Invention is to so communicate motion to the rack as to be
able to regulate to a nicety the tension of the yarn between the drawing rollers
and the bobbins or spools.
To carry out my Invention I place on the change or tumbler shaft a small bevel
wheel, which gears into a larger bevel wheel on a stud carried by a bracket bolted
to the spring piece of the frame, on the boss of the large bevel wheel is a small
spur pinion which gears into a spur wheel on the cross shaft which drives the
rack; on this shaft I place a change wheel to drive the rack which change wheel
has a greater or smaller number of teeth according to the hank roving; by this
means I am enabled to move the rack almost impercepibly to adjust the tension
of the yarn, instead of being compelled to move it not less than half a tooth as
heretofore. I place a hand wheel on the cross shaft so that it may be turned by
hand when desired.
My improvements are applicable to slubbing, intermediate and roving frames.

SPECIFICATION in pursuance of the conditions of the Letters Patent and of
an Order of the Lord Chancellor filed by the said John Cryer in the Great
Seal Patent Office on the 11th July 1882.
JOHN CRYER of. Dukinfield in the County of Chester, Machine Maker.
"IMPROVEMENTS IN ROVING FRAMES AND OTHER MACHINES FOR PREPARING
COTTON AND OTHER FIBRE."
The object of my Invention is to so communicate motion to the rack as to be
able to regulate to a nicety the tension of the yarn between the drawing rollers
and the bobbins or spools.
To carry out my Invention I place on the change or tumbler shaft a small bevel
wheel which gears into a larger bevel wheel on a stud carried by a bracket bolted
to the spring piece of the frame, on the boss of the large bevel wheel is a small
spur pinion which gears into a spur wheel on the cross shaft which drives the
rack; on this shaft I place a change wheel to drive the rack which change wheel
has a greater or smaller number of teeth according to the hank roving: by this
means I am enabled to move the rack to traverse the strap on the cone drums
almost imperceptibly to adjust the tension of the yarn, instead of being compelled
-to-move-the-rack-not-less-than-half-a-tooth-as-leretofore.--I-place-a-hand-wheel-
on the cross shaft so that it may be turned by hand when desired.
My improvements are applicable to slubbing intermediate and roving frames.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawings reference being
had to the figures and letters marked thereon.
Fig. 1 is an elevation and Fig. 2 is a plan of part of a roving frame to which my
Invention is applied.
a is the change or tumbler shaft on which is fixed the bevel pinion 6: this
bevel pinion gears into a bevel wheel c that turns on a stud fixed to the bracket d:
on the boss of the wheel c is a spur pinion e which gears into a spur wheel f fixed
on the cross shaft g which turns in a bearing at the end of an adjustable bracket g¹ :
on the cross shaft g is keyed the change wheel i, this change wheel may be of any
required size and it gears into and drives the rack h which regulates the strap on
the cone drums in the usual manner: k is a hand wheel fixed on the cross shaft g:
The bevel wheel c is so fitted on the stud fixed to the bracket d that it may be
drawn outward by the guide rod m to move the bevel wheel cout of gear with the
bevel pinion b so that the rack may be set by the hand wheel : the teeth of the
spur pinion e are wide enough to allow it to slide the required distance: n is a
retaining catch to keep the wheel c in gear with the pinion b when the rack has
been set this catch may be locked to prevent the rack being moved by the
operative after it has been set: on the tumbler shaft a are the ordinary catches
to change the motion for forming the taper of the bobbins or spools.
Having stated the nature of my Invention and described the manner of
performing the same.
I declare that I claim
The improved machinery for communicating motion to the rack to regulate
the tension of the yarn between the drawing rollers and the bobbins or spools of
slubbing, roving and intermediate frames substantially as herein described and
shown.
In witness whereof I the said John Cryer have hereunto set my hand
and seal this Seventh day of July One thousand eight hundred and
