PROVISIONAL SPECIFICATION left by Joseph Gilpin at the Office of the
Commissioners of Patents, with his Petition, on the 11th October 1855.
I, JOSEPH GILPIN, of Leeds, in the County of York, Manufacturer, do
hereby declare the nature of the said Invention of "AN IMPROVED RAISING GIG
TO BE EMPLOYED IN THE MANUFACTURE OF WOOLLEN CLOTHS" to be as follows:-
This Invention is designed for the purpose of enabling the well-known
operations of the "raising gig" to be carried on in two or more places or
parts of a piece of woollen cloth at one time, instead of at one part only, as
heretofore commonly practised, and the means by which this may be effected
are as follows:-Across the face of the teasling drum of an ordinary "gig mill"
I arrange and dispose the "raising gig" and parts in connection therewith
in the following manner; that is to say, I employ, for example, two breast
rollers, one at each side of the centre of the aforesaid drum, and immediately
over the centre of said drum I place a guide roller, over which the cloth to be
operated upon passes from the feeding roller over the breast rollers on to the
winding-on roller, the cloth being kept in a proper state of tension, and the
aforesaid breast rollers raised or lowered by an arrangement of worms and
worm wheels in connection with a shaft for actuating the same by hand, as
desired.
An important feature in this Invention consists in the use and employment

page_text: of certain mechanism of novel and improved construction for effecting the
reversing of the direction of motion of the teasling cylinder and feeding and
winding-on rollers when it is required to subject the cloth to a second teasling.
The following is the arrangement of mechanism which I employ for effecting
the above-mentioned reversing movement; that is to say, upon the axis of the
teasling drum there is a spur wheel gearing into a pinion for imparting motion
to said drum in the usual way, and I employ the above spur wheel for effecting
the before-mentioned reversing movement, by affixing a stud to the framing of
the gig mill. Upon this stud I place a bell crank lever, to the shorter arm of
which a spur pinion is attached, and gears into the aforesaid spur wheel, which
is on the axis of the teasling drum. This last-mentioned pinion is employed
for transmitting motion from said drum to that roller upon which the cloth is
being wound, for which purpose the axes of the feeding and winding-on rollers
have spur wheels of equal diameters fixed thereon respectively, so that
according as the pinion of the reversing lever is thrown into gear with one or
other of the spur wheels of the feeding and winding-on rollers, in like manner
the direction of movement of such wheels and parts connected thereto will be
reversed, and thus the cloth may be readily moved back and be again teazled,
which may be repeated as often as is necessary.
And although this improved "raising gig" is only here described as operating
upon two parts of the cloth at one time, it will appear evident that by the
above principle of construction, the cloth, if necessary, may be operated upon
at several parts simultaneously, thereby effecting a considerable saving of
time.
