PROVISIONAL SPECIFICATION.
Improvements in the Method of and Means for Weaving Selvedges
upon Piece Goods, so as to prevent Curled Edges or the like.
We, JAMES SMITH, Worsted Spinning Manager, of Digley, Holmfirth, and
BENJAMIN LITTLEWOOD, Cloth Finisher, of Burnlee, Holmfirth, both in the
County of York, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to weave selvedges upon piece good so as to
prevent curled edges upon such selvedges.
Upon each side of the loom, preferably upon the breast beam we mount a
pivotted or hinged finger, bracket, or the like, having a spring for keeping it in
position, a second finger or cam operated by a connecting rod upon the swinging
tree leg, raises the pivotted finger at intervals as desired.
The action is as follows;-As the shuttle is thrown across the loom and as
the sley beats up, the finger drops upon the weft nearest the sley, this weft is
held until the shuttle is returned, and as the sley beats up a second time, the
connecting rod and cam or bracket operates the pivotted finger raising same,
and leaving a loop in the weft at the edges of the piece, the finger again drops,
and the operation is repeated, upon both sides of the loom simultaneously.
By this means the loops so formed upon the edge of the piece, compensate,
for the natural shrinking of the weft, so doing away with the curling.
Or in place of the finger, we may employ a wire fixed upon the back heald
shaft to run into the temple, this wire as the heald rises and falls according to
the pick of the shuttle either under or over, forms the loop upon the edge of
the piece as before described.

Improvements in the Method of and Means for Weaving Selvedges

We, JAMES SMITH, Worsted Spinning Manager, of Digley, Holmfirth, and
BENJAMIN LITTLEWOOD, Cloth Finisher, of Burnlee, Holmfirth, both in the
County of York, 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:-
The object of our invention is to weave selvedges upon piece goods so as to

page_text: prevent curled edges upon such piece goods, consequent upon the dyeing and
finishing process, through which they have to pass, or from other similar causes.
DESCRIPTION OF DRAWINGS.
Fig. 1 is an end view of our improved apparatus applied to looms, and showing
its position as the shuttle is thrown across the loom and preparatory to the sley
beating up.
Fig. 2 is an end view of our apparatus, showing the traverse of the finger
when released from the loop upon the return of the sley.
Fig. 3 is a plan of Fig. 1.
Fig. 4 is a plan of a modification of our improved method and means for
forming the loop upon the edges of the piece for the purposes before described.
Upon each side of the loom, and preferably upon the breast beam A', or upon
two cross rods A³, adjacent thereto, we mount a suitable bracket A, carrying a
stud B, upon which is a finger, bracket or the like C. Upon the bracket A is
also a slide, finger, or arm D, working in a slot A and having a pin or projection E
at one end, to assist in forming the loop upon the selvedge; a lever F upon the
stud B, is operated at intervals by a projection or loop G, upon the sley board G¹.
The action is as follows:-As the shuttle is thrown across the loom, the weft
passes round the pin E, upon the finger D, and as the sley beats up, a loop .E¹
is formed upon the selvedge of the piece E2; upon the return of the sley, the
arm or loop operates upon the lever F, which, by means of an incline A³ in
the slot A, and the finger C striking the arm D, immediately causes the same
to lower, disengaging the pin E from the loop already formed, the arm D then
moves forward in the manner shown in dotted lines at Figs. 1 and 2.
A spring H returns the sliding arm D into position immediately it is released
by the loop G, upon the sley board; the arm D, and pin E, again holding the
weft nearest the sley, so that when the shuttle after being returned is again
thrown across, and the sley again beats up, a second loop is formed, by this
means we form a loop in the weft along the selvedges of the piece alternately,
upon each beat up of the sley which compensates for the natural shrinking of
the weft during dyeing, finishing and the like, so doing away with the curling.
Or in place of the above arrangement, we may employ a wire J, see Fig. 4,
fixed preferably upon the back heald shaft K, this wire J passes into and is held
by the temple L, as the heald rises and falls according to the pick of the shuttle
either under or over, the said wire forms the loop upon the edge of the piece,
and as the piece, during weaving passes on to the beam, the loops pass off the
end of the wire, so automatically releasing themselves.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. In forming the selvedges upon piece goods the use and employment of
bracket A, in which is a slot A4, having an incline A³, stud B, finger C, sliding
arm D, pin or projection E, and spring H, operating, and operated by the sley
board, in the manner, and for the purposes substantially as shown and described.
2. In forming the selvedges upon piece goods, the use and employment of a
wire J in the manner and for the purposes substantially as set forth.
