PROVISIONAL SPECIFICATION.
Improvements relating to the Lease Rods of Looms.
We, PETER OAKES, of 91, Gordon Street, Stoneyholme, Burnley, Weaver, and
JAMES LEIGH, 66, Curzon Street, Burnley, Gentleman, do hereby declare the
nature of this invention to be as follows:-
2:
The object of this invention is the production of "cover on fabrics, whilst being
woven in looms; and for this purpose we employ two side arms, attached to the
movable back rest. At the outer extremity of these are fixed either one or both
lease rods, which partake of the vibratory motion of the said side arms. The
vibratory motion of the lease rods causes the lower part of the warp threads to
assume an angle in excess of the upper warp threads in shedding, by which means a
constant rolling of the weft threads is effected at the fell of the fabric by the
alternate tightening of each half of the warp threads, so as to cause a fur or nap to
be thrown upon the face of the fabric technically known as "cover."
The said rod or rods are adjustable in their relation to the side arms, so as to be
capable of adjustment in a vertical or horizontal direction as may be required.

COMPLETE SPECIFICATION.
Improvements relating to the Lease Rods of Looms.
We, PETER OAKES, 91, Gordon Street, Stoneyholme, Burnley, Weaver, and
JAMES LEIGH 66, Curzon Street, Burnley, Gentleman, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This invention of improvements relates to lease rods of looms, and consists of an
arrangement of side arms as a means of connection between the said lease rods and
the vibrator or movable back rest, for the purposes hereinafter described.
In Figs. 1 and 2 of the accompanying drawings, A represents the vibrator or
movable back rest, to which is fixed side arms constructed in two parts B and C,
one capable of moving upon the other for adjustment to bring the lease rods near
to or further from the vibrator. The parts are then securely fixed by a bolt, and
partake of the vibratory movement of the back rest A.
The lease rods D, seen in Figs. 3 and 4, are inserted in the recesses F and G,
formed in the part C. The vibratory movement thus imparted to the lease rods
will cause the lower warp threads to assume an angle in excess of the upper warp
threads in shedding, by which means a constant rolling to and fro of the weft
threads is effected at the fell of the fabric, so as to cause a fur or nap to be thrown
upon the face of the fabric, technically known as
66 cover." Instead of the lease
rods being inserted in the recesses in the part C, they may be inserted in recesses
formed in a tilting plate H, mounted at the extremity of the part C, as seen in
Figs. 3 and 4.
The side arms may be used also with advantage as a means of connecting the
lease rods to the back rest, and without partaking of the vibratory movement of
the back rest, when not required to produce cover as seen in Figs. 5 and 6. In
this case the side arms are jointed at I to a bracket K³, which may be either fixed
to the movable back rest seen in Fig. 1, or to one of a pair of shedding rods K of
another form of back rest in common use.

page_text: The side arms may, if desired, consist of flexible metal rods, upon which are
mounted the lease rods D, as seen in Fig. 7. These flexible rods may be either
secured to one of the shedding rods K, or to the vibrator A.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed; we declare that what we
claim is :-
The employment of side. arms as a means of connecting the lease rods to the
vibrator or back rest, substantially as described and illustrated for the purposes set
forth.
