WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of January, in the
year of our Lord One thousand eight hundred and seventy, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said John Dawson and Thomas Constantinc
Fawcett, Her special licence that we, the said John Dawson and
Thomas Constantine Fawcett, our executors, administrators, and assigns,
or such others as we, the said John Dawson and Thomas Constantine
Fawcett, our executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term thercin expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "Im-
PROVEMENTS IN RAISING GIGS USED IN THE PROCESS OF RAISING THE NAP' OF
WOOLLEN CLOTH OR OTHER FABRICS," upon the condition (amongst others)
that we, the said John Dawson and Thomas Constantine Fawcett, our
executors or administrators, by an instrument in writing under our, or
their, or one of their hands and seals, should particularly describe and

page_text: ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Dawson and Thomas
Constantine Fawcett, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement and
accompanying Sheet of Drawings (that is to say) :-
.
'
This Invention has for its object to facilitate the process of raising
the nap of woollen cloth or other fabrics and to economise room or
space occupied by the machinery. These improvements relate to the
single cylinder raising gigs, and consist in mounting: the scray with the
drawing rollers on the top of the framework of the machine over or
above the cylinder, and by preference we use a semicircular travelling
scray with the drawing rollers combined therewith; also in the appli-
cation of any ordinary reversing motion, and arranging the same so that
the machine may be turned in either direction at pleasure, or backward
and forward alternately; also in the use in combination with this
machine of two spirally grooved breast or expanding rollers, the spirals
running in opposite directions from the middle thereof; and in the
application of a carrying roller over the cylinder, whereby we obtain
action on the cloth or fabric at two different points or parts of the
cylinder.
In order that our said Invention may be fully understood; we herein
give reference to the accompanying Sheet of Drawings of an ordinary
raising gig shewing our improvements applied thereto..
Fig. 1 is an end. elevation; Fig. 2 is the opposite end elevation; and
Fig. 3 is the plan or top view of the same.
A is the cylinder mounted in framework B upon a shaft C in the usual.
manner, and to which motion is given by driving, pullies, D, D¹, and. D².
These pullies however are of the reversible character, D being fixed on the
shaft C, while D¹ runs loose thereon, and D2 is fixed upon a boss on which
is also fixed a toothed wheel D³ gearing in a broad toothed wheel D'
carried on a stud fixed in the framework which gears with a wheel D³ on
another stud, and. which also gears in a wheel D° fixed on the shaft C
so as to effect a reversing action of the cylinder. E is the framework-of
:

page_text: a semicircular scray mounted on the top of the framework B and secured
thereto by bolts E1 and E2. This framework carries a series of rollers F
geared together by a train of toothed wheels F' and F. The said frame
also carries two sets of drawing rollers G 1, 2, 3, and H 1, 2, 3, to which
motion is communicated by two separate trains of gear wheels I-1, 2,
3, 4, 5, and J 1, 2, 3, 4, 5, which are in gear with a wheel K carried
on a stud fixed to the frame B and in gear with a small wheel L.fixed
on the shaft C, which therefore gives motion to both sets of drawing
rollers in the direction required. 'M and M', are the two breast or
expanding rollers mounted in the ordinary racks in the usual manner,
but to each said roller axis is connected a jointed arm N, and which arms
are also hinged on the axis of the wheels I and J', on the side of which
are also attached wheels P, which are in gear with wheels Q carried on
studs fixed at the joints of the arms N, and these wheels Q gear with
pinions or small wheels R fixed on the axis of the expanding rollers M
and M', so that positive motion can be given to these rollers in whatever
position they may be placed by the racks. S is the carrying roller, which
is supported by bearings formed in or fixed to the frame over or above
the cylinder for the fabric to pass over from one to the other breast' or
expanding roller, so that it may be operated upon by the cylinder
at two separate points or places simultaneously; T and T are stud
plates or cranks fixed respectively on one of the drawing rollers in each
set and connected by rods T2 and T3 to catch levers T and T, which
catches taking into ratchet wheels T and T attached respectively to
two of the wheels F2. These catches can be placed into or out of contact
with the teeth of the ratchet wheels by means of a slide bar U, on
which are two inclines or wedges U₁and U2 which pass through loops
V and V attached to the said catches. By means of these catches and
ratchet wheels intermittent motion is given to the rollers F in either

shewn in its passage through the machine by the dotted lines W,
surplus length laying in folds on rollers F of the scray. X & X' are
pressing rollers carried on levers X2 and X³, which are connected by a
rod X so as to be operated by the attendant to bring cither of them
into action according to the direction of travel of the fabric; Y and Y'
are levers carrying guide rollers for the fabric to pass over or in contact
with to guide it in its passage through the machine, which are brought
into action respectively by means of the handles Z and Z', shafts and
worms Z and Z³, gearing into wheels Z' and Z³ fixed on the axis of the

page_text: levers Y and Y. The parts marked * are ordinary parts of apparatus
for cutting when taking the fabric out of the machine.
Having thus described the nature of our said Invention, and shewn
by Drawings and description thereof how the same is or may be carried
into effect, we would have it understood that we make no claim to any
of the parts of the apparatus separately considered, nor do we confine
or restrict ourselves to the precise details of combination and arrange-
ment or mode of operation thereof; but what we claim as our Invention
is,
Firstly. The combining a cray whether semicircular or otherwise and
drawing rollers with a raising gig by mounting it on the top, in manner
substantially as shewn and described.
Secondly. The application to a single cylinder raising gig of any
ordinary or suitable reversible motion, arranged so that the machine
may be turned in either direction at pleasure.
Thirdly. The combination of two breast or expanding rollers with a
single cylinder machine in such manner as to be driven by gearing or
other similar positive means.
Fourthly. The application of a roller over or above the cylinder for
the fabric to pass over, so as to obtain action by the said cylinder at
two separate points or parts of the fabric simultaneously, as shewn and
described.
In witness whereof, I, the said John Dawson, for and on behalf
of myself and the said Thomas Constantine Fawcett, have here..
unto set my hand and seal, this Twentieth day of July, in the
year of our Lord One thousand eight hundred and seventy.
Signed, sealed, and delivered by the
within-named John Dawson, in
the presence of

Patent Agent,
