Year: 1880

page_text: LETTERS PATENT to George William Hawksley, of Bright Side Boiler Works,
Sheffield, in the County of York, and William Lumb, of Belle Isle Dye Works,
Wakefield, in the County aforesaid, Crabber, for an Invention of "IMPROVE-
MENTS IN MACHINERY FOR CRABBING, SQUEEZING, AND FINISHING WOVEN
AND KNITTED FABRICS."
PROVISIONAL SPECIFICATION left by the said George William Hawksley
and William Lumb at the Office of the Commissioners of Patents on the
9th October 1880.
GEORGE WILLIAM HAWKESLEY, of Bright Side Boiler Works, Sheffield, in the
County of York, and WILLIAM LUMB, of Belle Isle Dye Works, Wakefield, in the
County aforesaid, Crabber. "IMPROVEMENTS IN MACHINERY FOR CRABBING,
SQUEEZING, AND FINISHING WOVEN AND KNITTED FABRICS."
The object of this Invention is to so construct the machinery that the "piece" or
fabric during the process of crabbing, squeezing, and finishing, shall be stretched
laterally or in the direction of its width in addition to the stretching in the
direction of its length. The stretching of the piece simultaneously with the crabbing,
or just preparatorily to the finishing, secures a more highly finished cloth than is
the case when the finishing is disturbed by after operation of stretching or
tendering, and to facilitate the winding the piece upon the steaming rollers.
Machines for purposes aforesaid, according to this our Invention, are constructed
after the manner of an ordinary crabbing machine, there being applied to and in
combination therewith "expanding rollers" having screw adjustment, the said
rollers, by preference, having discs and diagonal grooves for the purpose of guiding
the bars of the roller, and during their receding and advancing movements, in
addition, each expanding roller is provided with an adjustable radial guide rod,
under which the piece passes to the expander, the position of the guide rod
determining what proportion of the circumference of the expander is to be encircled
and gripped by the piece under operation, the tension on and frictional grip of the
piece as drawn through the machine being the means whereby the expanding
[Price Bd1

page_text: roller is driven. The piece after passing the expander nearest the delivery end of
the machine is passed under and over the ordinary delivery rollers to the steaming
rollers, which latter, and the piece thereon, are pressed upon or against one of these
rollers and receives rotation therefrom, there being wheel, or pulley and weights,
or lever and weight, by means of which the degree of hardness or tightness of the
wrapping of the piece around the steaming rollers is determined. A hinged clip
and pin device at the end of the pendant arms serves to secure the necks or axles of
the steaming rollers, and it will be understood that the expanding roller and
devices connected therewith may be applied between one or more pair of the
ordinary rollers and in front of the delivery rollers of the machine, as desirable, or
according to the nature of the goods or pieces under operation and the "finish"
required.
It will be understood that as a substitution for the expanding roller referred to a
tentering or temple device, a roller having right and left handed vanes, or other
like appliance may be used for securing the lateral strain upon and stretching the
piece in the direction of its width.

the said George William Hawksley and William Lumb in the Great Seal
Patent Office on the 7th April 1881.
GEORGE WILLIAM HAWKESLEY, of Bright Side Boiler Works, Sheffield, in the
County of York, and WILLIAM LUMB, of Wakefield, in the County of York,
aforesaid, Crabber. "IMPROVEMENTS LN MACHINERY FOR CRABBING, SQUEEZING,
AND FINISHING WOVEN FABRICS."
The object of this Invention is to so construct machinery that the "piece" or
fabric during the process of crabbing, squeezing, and finishing, shall be stretched
laterally, or in the direction of its width, in addition to the stretching in the
direction of its length. The stretching of the piece simultaneously with the
crabbing, or just preparatorily to the finishing, secures a more highly finished cloth
than is the case when the finishing is disturbed by after operation of stretching or
tendering, and to facilitate the winding the piece upon the steaming roller.
Machines for purposes aforesaid, according to this our Invention, are constructed
after the manner of an ordinary crabbing machine, there being applied to and in
combination therewith "expanding rollers," the said rollers, by preference, having
discs and diagonal grooves for the purpose of guiding the bars of the roller during
their receding and advancing movements; in addition each expanding roller is
provided with an adjustable radial guide rod, under which the piece passes to the
expander, the position of the guide rod determining what proportion of the
circumference of the expander is to be encircled and gripped by the piece under
operation, the tension on and frictional grip of piece as drawn through the
machine being the means whereby the expanding roller is driven. The piece after
passing the expander nearest the delivery end of the machine is passed under and
over the ordinary delivery rollers to the steaming roller, which latter, and the piece
thereon, are pressed upon or against one of these rollers and receives rotation
therefrom, there being wheel, or pulley and weights, or lever and weight, by means
of which the degree of hardness or tightness of the wrapping of the piece around
the steaming rollers is determined. A hinged clip and pin device at the end of the
pendant arms serves to secure the necks or axles of the steaming roller, and it will be
understood that the expanding roller and devices connected therewith may be applied
between one or more pair of the ordinary rollers and in front of the delivery roller
of the machine, as desirable, or according to the nature of the goods or pieces under
operation, and the "finish" required. It will be understood that as a substitution
for the expanding roller referred to, a tentering or temple device, a roller having
right and left handed vanes, or other like appliance may be used for securing the
lateral strain upon and stretching the piece in the direction of its width.
Such being the nature and object of this our said Invention, we will now proceed
to describe the same in detail, and in order that the Invention may be fully
understood we have hereunto annexed 2 Sheets of Drawings, and have marked the
same with figures of reference, like figures refer to like parts in the various

page_text: "piece" or fabric in the direction of its width; at 4 is a stretching bar device
under which the piece 5 is passed, the bar 4 being carried by the ends of the lever
arms 6, 6, the said levers being carried by cross shaft 7, applied by standard 8, 8,
fixed to the end frames of the machine; at 9 is a hand lever having fulcrum on a
shaft 7; at 10 is a slotted guide bar, by means of which and the lever 9, and
the holding screw 11, the stretching bar 4 may be secured in any position
relative to the expanding roller 3, so that as the bar 4 is raised or lowered, so will
the piece or fabric 5 embrace or bind upon or around a greater or less surface
circumference of the separating roller 3 (the bar 4 may, however, be set or adjusted
by means of a pinion and segment wheels); the piece or fabric 5, after passing
from the expanding roller 3 passes under the roller 12, over or around roller 13 to
the steaming roller 14. The roller 12 is the "driver" or driven roller, the piece
passing between the nip of 12 and 13, thence direct to and around 14, admits the
use of stronger acids, or scour piece being more thoroughly cleansed and resulting
in better "finish."
The
It will be seen that the roller 14 is suspended by pendant arm 15 (one for
each side) in such manner as that the contact between roller 14 with roller 13 the
rotation of the latter drives the steaming roller 14 at such surface speed as to
take up the cloth as supplied thereto without any undue straw during the
constantly changing or increasing diameter of the roller and cloth thereon.
journals or axles of 14 are received and worked within the hinged neck 16.
The arms 15 are carried by cross shaft 18; at 19 is a lever arm and weight 20,
by means of which, and change of weights, the pressure between rollers 13 and 14,
and consequently the tightness or "hardness" of wrapping the piece or fabric around
and upon the roller 14 is determined.
It will be seen that the suspension or mounting the roller 14 so as to be in
contact with the delivery roller 13 prevents any undue technical strain upon the
piece in the direction of its length, which would, of course, in great measure detract
from and eradicate effect produced when expanding roller 3 is used, as it must be
understood the rollers 13 and 14 may be used in combination on an ordinary
crabbing machine, that is to say, a machine not having the expanding roller 3
applied. 21 is a lever for taking the weight off the roller 14 whilst the latter is
being put in or removed from the clips.
Having thus fully described the nature and particulars of this our said Invention,
together with the manner in which the same is to be performed or carried into
practical effect, we would have it understood that we claim as our Invention,―
Firstly. The use in combination of expanding roller or temple 3, stretching
bar 4, and winding on roller 14, substantially as described and illustrated by
Drawings.
Secondly. The use in combination of rollers 12, 13, and 14, in manner as
described and substantially shewn by Drawings.
In witness whereof, I, the said George William Hawksley, have, for and on
behalf of myself and the said William Lumb, hereunto set my hand and
seal, this Fifth day of April, in the year of our Lord One thousand eight
hundred and eighty one.
