page_text: LETTERS PATENT to Benjamin Schofield, of Dewsbury, in the County of York,
Gentleman, for the Invention of "IMPROVEMENTS IN RAISING GIGS' EMPLOYED
IN FINISHING WOOLLEN AND OTHER FIBROUS MATERIALS."
Sealed the 20th November 1877, and dated the 14th July 1877.
PROVISIONAL SPECIFICATION left by the said Benjamin Schofield at the
Office of the Commissioners of Patents on the 14th July 1877.

FIBROUS MATERIALS."

This Invention relates to that class of machinery known as raising gigs"
employed in raising the nap or pile on woven or felted fabrics, and the object of
the Invention is to so arrange the construction of the machine as to operate upon
the material in two or more places at the same time, and thereby pass more pieces
through the machine in a given time than can be done at present.
The improvements consist in combining with the ordinary arrangement of rollers
or "running gigs" one or more intermediate rollers, whereby the piece is brought
into contact with and touches the "raising cylinder" in two or more places at the
same time, and the piece is relieved or eased botween the points of contact by the
other rollers.
The ordinary racks and pinions are employed for regulating the quantity of
material to be raised or operated upon.

BENJAMIN SCHOFIELD, of Dewsbury, in the County of York, Gentleman.
"IMPROVEMENTS IN
⚫ RAISING GIGS' EMPLOYED IN FINISHING WOOLLEN AND
OTHER FIBROUS MATERIALS."
This Invention relates to that class of machinery known as "raising gigs"
employed in raising the nap or pile on woven or felted fabrics; and the object of
the Invention is to so construct the machine as to operate upon or to "raise" the
material in two or more places at the same time, and thereby pass more pieces
through the machine in a given time than can be done at present.
The improvements consist in combining with the ordinary arrangement of rollers
or "raising gigs "one or more intermediate rollers or rods, whereby the piece in
passing through the machine is brought into contact with and touches the raising
cylinder in two or more places at the same time, and the piece is relieved or eased
between the points of contact by the said rollers or rods.
The ordinary racks and pinions or other equivalent are employed for regulating
the quantity of material to be raised or operated upon.
In order that this Invention may be more readily understood I herein give
reference to the accompanying Sheet of Drawings illustrative thereof, wherein
Fig. 1 is a cross section of a "raising gig," shewing so much of this class of machine
as is necessary to illustrate my Invention.
A is the raising cylinder, around the periphery of which are "teazles" for raising
the nap or pile on fabrics as they come in contact with them. B and C are the
ordinary rollers, which have hitherto been employed for guiding and holding the
fabric on to the "teazles," the length of material to be operated upon between the
said rollers being regulated by the rack and pinion D. E is one of my additional
or intermediate rollers, which is placed, as shewn, between the rollers B and C.
This roller is capable of regulating to the greatest nicety the length or quantity of
fabric to be "raised" by means of the screw G and bevil wheels J, K, and hand
wheel L.
In some cases the rollers B and C may be removed further apart, as shewn in
Fig. 2, and two or more rollers H and I may be used, and the fabric "raised" in
several places at one and the saine time.
By means of this Invention more pieces may be raised by one machine in a given
time than can be done at present, thus a great saving is effected, as will readily be
seen by any one conversant with the trade.
Having now described the nature and particulars of my Invention, and shewn
how the same may be put into practice, I would have it understood that I do not
limit myself to the number of rollers employed, nor to the method of regulating
the length of piece to be "raised;" but what I consider to be new, and therefore
claim as my Invention, is the use and employment of rollers or rods E, H, and I, as
and for the purpose herein shewn and described.
In witness whereof, I, the said Benjamin Schofield, have hereunto set my hand
and seal, this Twenty-seventh day of November, in the year of our Lord
One thousand eight hundred and seventy-seven.
Signed, sealed, and delivered by
the within-named Benjamin
Schofield, in the presence of
HENRY THORP.
BENJAMIN SCHOFIELD. (L.S.)
