PROVISIONAL SPECIFICATION.
Improvements in Machines for Laying, Folding, or Plaiting Fabrics.
We, JOHN HALL and ROBERT HALL, both of the firm of Robert Hall and
Sons, of Hope Foundry, Bury, in the County of Lancaster, Engineers, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to improvements in machines for laying folding or
plaiting fabrics, and our improvements consist in a novel arrangement of
mechanism for locking and releasing the clips or holders which grip and hold
the cloth or other fabric at each side or end of the table upon which it is folded
or plaited.
In carrying our improvements into effect we connect each swivel or hinged
clip by a link to a pivoted scroll or cam lever to which is connected a spring
or from which a weight is suspended in such a manner as to always draw the
clip downward on to the fabric, and when down the clip is locked in position by
the link coming in contact with a projection upon the cam lever or upon the
frame and by the centres of the clip, the centre of the scroll or cam lever and
the centres of the link all coming into or forming one straight line. The clips
are alternately released and raised by means of a stud or projection on the
rocking arm which carries the reciprocating shovel or carrier which lays the
cloth in folds or plaits; this stud or projection as the rocking arin approaches
the end of its traverse presses back the cam lever and by the link raises the
clip until the cloth carrier begins to move in the reverse direction when as the
rocking arm recedes, the stud or projection thereon moving with it allows
the spring or weight to again draw down the clip, the corresponding clip on the
other side remaining down and locked until actuated by the stud or projection
on the rocking arm as above described.

Improvements in Machines for Laying, Folding, or Plaiting Fabrics.
We, JOHN HALL and ROBERT HALL, both of the firm of Robert Hall and
Sons, of Hope Foundry, Bury, in the County of Lancaster, Engineers, 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 :-
Our invention relates to improvements in machines for laying folding or plaiting
fabrics, and our improvements consist in a novel arrangement of mechanism for
locking and releasing the clips or holders which grip and hold the cloth or other
fabric at each side or end of the table upon which it is folded or plaited.
And in order that our invention may be fully understood and readily carried
into effect we will describe the accompanying drawing which is a side elevation of
a folding or plaiting machine to which our improvements have been applied.

In this view, a designates the frames of the machine, the inspection table,
the driving shaft, d the flywheel and e a pinion fixed on the shaft which gears
into a spur wheelf fixed on the countershaft On the countershaft is also fixed
the arm which by a link i is connected and so imparts a to and fro motion to the

page_text: rocking arm which is fulerumed at and supports the reciprocating shovel or
carrier by which the cloth is folded or plaited.
In carrying our improvements into effect we connect each swivel or hinged
clip m by a link n to a pivoted scroll or cam lever o to which is connected, by a
chain, cord or strap p, a spring 7 secured to the adjustable arm which carries the
centre m on which the clip m is hinged, or a weight may be suspended from the
scroll or cam lever o in such a manner as to always draw the clip m downward on
to the fabric, and when down the clip is locked in position by the link n coming in
contact with a projection upon the scroll or cam lever o or upon the frame a, and
by the centres of the scroll or cam lever o, and the centres of the link all coming
into or forming one straight line. The clips m are alternately released and raised
by means of a stud or projection j' on the rocking arm; which as the said arm
approaches the end of its traverse presses back the scroll or cam lever o, which is
pivoted at o' to the arm r, and by the link n raises the clip m into the position
shown on the left hand side of the drawing until the shovel or cloth carrier
begins to move in the reverse direction, when as the rocking arm i recedes the stud
or projection thereon moving with it allows the spring or weight as the case
may be to again draw down the clip m into the position shown on the right hand
side of the drawing, the corresponding clip on the other side remaining down and
locked until actuated by the stud or projection j' on the rocking arm j as above
described.
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 :-
1. In combination a swivel or hinged clip a link and a scroll or cam lever
connected together and arranged in such a manner that the said clip is locked upon
the fabric when the centres of the link and scroll are in one and the same straight
line all substantially as herein set forth.
2. The combination with the rocking arm which supports and operates the
reciprocating shovel or cloth carrier, of swivel or hinged clips each connected by a
link to a pivoted scroll or cam lever, and arranged to be drawn downward on to
the fabric by a spring or weight, and to be locked in that position until released by
a stud or projection on the rocking arm, substantially as herein set forth.
3. The combination and general arrangement of parts embodying our improve-
ments in machines for laying folding or plaiting fabrics substantially as herein
described with reference to the accompanying drawing.
