or Facilitating the winding thereof upon Boards.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 relates to that class of rigging machines in which the web is drawn
over the surface of angularly sei edges or bars, and the great merit of this inven
tion over the rigging machines heretofore employed for folding fabrics, and which
renders the same especially adapted for folding finished woolen fabrics, consists in
the fact that while the longitudinal portion of the web at one side of the fold line, is
brought forward to the winding board subject to lateral deflection caused by the
action of oblique turning edges, the opposite portion of the web will be brought forward
to the winding board without lateral deflection, and will thus tend to steady the web
in its passage over the said oblique turning edges; so that the edges of the web can
be readily kept in the required fine, and the ends of the plies be brought out true with
each other, and square with the fold line, which is highly desirable in packing elastic
woolen fabrics, and while I secure by my invention the above mentioned desirable
results, I also present the back of the web to the hands of the operator in guiding the
same, so that his hands will not mar the [face-finish of the fabric, while the passage of

page_text: the face of the web over the polished turning edges in the proper direction of the
nap, does not tend to injure the said face finish. And my invention consists in the
improved arrangement of the turning edges or bars, and in the combination of the
turning edges with improved grip rolls, and also with an improved adjustable tension
bar or roll, and fold and edge guides, and in improved details of construction.
In the accompanying drawing

concealed mechanism.
Figure 2 represents a vertical section taken on the line. Figure 1.
Figure 3 is a detail end view of the grip-rolls with the interlocking gears

Figure 4 is a detail view of the friction strap for producing the desired tension upon
the fabric by means of the grip rolls.
Figure 5 represents a section taken on the line of Figure 4.
Figure 6 is a detail section shewing the screw mechanism for operating the clutch
to hold the winding board.
Figure 7 is a detail section of an adjustable guide for the edge of the web, at the
forward turning bar.
A A are upright standards, which are connected to each other by means of ties B,
and to the underside of the table C, are secured the brackets D, for holding the
pintles E, which are loosely held in the standard bearings F. The movement of the
table Cupon its pintles E is limited in the backward direction, by means of the
curved arms G, attached to the standards A, A, and by this means the table is
supported in about a horizontal position, or with a slight upward inclination toward
the rear side. The table C is provided with an elevated rail H, which forms a slot
opening I, near the rear edge of the table; and an angularly deflected bar J is made
to extend from the stand K at the front left hand corner of the table, to a stand Z at the
rear right hand corner of the same the said bar serving to form two of the turning
edges a and b of the machine, the angular point e being located at the fold line, or
folding point of the web. A bar M, having a turning edge d is also made to extend
from the stand N, at the rear left hand corner of the table, to the angular point E the
outer end of the said bar being supported in a horizontal direction by means of the
bar O secured at one end to the end of the bar M, and at the other end to the elevated
rail H, at the rear edge of the table.
To the under side of the bar J are also attached the bars P, which extend back
horizontally from the bar J, their rear ends being turned downward and attached to
the elevated rail H. The bars P serve to support the web in a proper horizontal
position, and thus facilitate its passage around the turning edges, whereby it is
brought from an outspread to a folded condition.
Upon that portion of the bar J, which is parallel with the front edge of the table, is
placed the adjustable edge guide Q, which is shewn in enlarged section in Figure 7 the
said guide being cored out to receive the bar J, and also having a chamber e in which
is placed the flat spring which serves to create sufficient friction between the guide
and bar, to hold the said guide in its set position on the bar. The table C is also pro-
vided with a shallow recess g which extends lengthwise of the table, and is covered by
means of the plate R, provided with the slots h h. Centrally of the table in the
recess g is placed the gear i which revolves upon the upright stud secured to the table.
The gear engages with the opposite racks formed at the inner ends of the
opposite bars S, S, the outer ends of which extend upward through the slots h h of the
plate R and to the said outer ends are attached the side guides T T which serve to
guide the edges of the out-spread web over the surface of the table C in its entrance
to the machine. The side guides T, T being thus connected to each other by means of
the racks and gear, a movement imparted to one of the said guides will be transmitted
in opposite direction to the outer guide. To the stud extending upward from the
table C, is pivotted the fold-guide U which serves by extending between the folds of
the web to the fold line, to preserve the said fold-crease in its proper position for

page_text: entrance between the grip-rolls V, V1 the said fold guide being adapted for movement
to one side while threading the machine.
The lower grip roll V is held in sliding box m, which are adapted for slight vertical
movement in the slot n of the opposite stands W W, which are attached to the rail H;
and under each of the boxes m at opposite ends of the roll, is placed a spiral spring o.
The upper roll V is held at each of the stands W in an inclined slot p provided at its
lower end with a bearing 7 and at its upper end a rest r. When the upper roll V
is brought into its bearings y, the rolls VV₁ will be forcibly held together by means
of the spiral springs o so that the folded web which passes between the said rolls will
be firmly held thereby.
The rolls V V are preferably covered with india rubber, in order to provide a
frictional surface, and with interlocking gears s, which serve to cause both rolls to
revolve at the same rate of speed.
The friction
Upon the shaft of the lower roll V is placed the grooved friction wheel upon which
is placed the friction strap formed in two parts which are held together by means of the
screws vv under the heads of which are placed the spiral springs w.
strap u is prevented from rotation with the wheel by means of the head of the screw v
which strikes against the top of the stand which is attached to the rail H under the
said friction strap.
By adjusting the tension of the springs w by means of the
screws the tension of the folded web at the package roll, may be either increased
or diminished. The package winding mechanism is supported in a position opposite
one end of the table C, by means of the upright stands A' A' which are secured to
each other by means of the head-bar B₁ and the tie-bar C. To the driving shaft D¹
at opposite sides of the machine are secured the gears E' and at the middle of the
shaft D' is secured the hand wheel a¹. The gears E engage with intermediate
gears F which revolve loosely upon suitable fixed studs and engage with the
gears G which serve to drive the clutches H1 H2 for holding the board c¹ upon which
the folded fabric is to be wound. The clutch H' which is in line with the fold crease
of the web, is held upon its shaft in one position, while the clutch H2 is made movable
toward and from the said clutch H', in order to provide for the insertion of the
board e¹ and for removing the completely wound package.
The construction of the screw operated spindle of the movable clutch H³ is shewn
in enlarged section Figure 6, in which the clutch H2 is screwed upon the end of a
hollow spindle I which is provided at its opposite end with the female thread d
fitting the thread of the operating screw J' and also with a longitudinal groove or slot e¹.
Over the hollow spindle I is placed the hollow shell K provided at its inner end with
the flange or collar and at its outer end with the contracted aperture g' which
embraces the collar of the screw. And the spindle I' is connected to the shell K'
so as to revolve therewith; by means of the pins, which are held in the shell K¹ and
pass into the groove or slot e¹. The bearing L' is bolted to the frame A and the gear
Gis secured to the outer portion of the shell K', by means of the set screw j and
upon the outer end of the screw J₁ is placed the hand wheel M¹ which is secured
thereto by means of the nut A'. By turning the hand wheel M', the spindle I,
and clutch H2 may be caused to advance or recede from desired. Length-
wise of the table C and near the slot opening I, with its lower side slightly above
the surface of the table, is placed the friction roll N¹ at one end of which
is placed the small gear or catch wheel the teeth of which are engaged
by the forward end of the spring catch m¹ which is secured to the top of
the rail H and by means of the catch m¹ the roller N can be held, so that any
desired portion of its periphery will come in contact with the surface of the fabric,
to be folded. Lengthwise of the roll N¹, is secured the friction strip n' which
may be made of cloth, or other suitable material, and by turning the roll N₁ so as
to bring this friction strip, more or less, in contact with the web, the tension of the
web in its passage over the turning edges can be regulated to suit the varying requirements
of the fabric. The front portion a of the bar J which is perpendicular to the fold line
of the web is preferably made thicker than the oblique portion 6 of the said bar, so
that its upper surface will lie in about the same plane, with the upper surface of the

page_text: bar M, as shewn in figure 2, and this thickening of the bar J, is to commence at the
corner c and he cut backward at an angle of about forty-five degrees, leaving a narrow
space o at the edge of the bar M, to allow the free passage of the fabric in its upward
movement around the outer end of the turning edge d of the said bar. In threading
the machine the web in its outspread condition is first passed over the upper surface
of table C, between the side guides T T, which are adjustably held by means of
racks and gear i at equal distances from the centre, or fold line, and a sufficient
length of the web is to be passed forward to drop through the slot opening I. Then
the table is to be turned to an upright position upon its pintles E, and the web which
is still in its outspread condition is to be brought back over the friction roll N' and
carried downward to the lower edge of the table, and upward to the grip rolls V V1,
between which the web is to pass in a folded condition; the right hand longitudinal
portion of the web, passing over the oblique turning edge of the bar J, and being
thence deflected laterally at a right angle to its former course, until it encounters the
oblique turning edge of the bar M, the said turning edge serving to again deflect
the said portion of the web to a direction at right angles to its previous lateral course;
and by this means transferring the right hand longitudinal portion of the web over
to the left hand side of the machine; the left hand portion of the web, at the same
time, passing over the thickened turning edge a and thence in a forward direction
direct to the grip rolls V V₁. The folded end of the web can be pressed between the grip
rolls, by turning the same by hand, while the end of the web is held between the thumb
and fingers, and when the web is properly held by the said rolls, the table C can be
turned to its horizontal position, and the folded web carried to the winding board c¹
upon which the package is to be formed.
Although in threading the machine the forward end of the web can be readily drawn
between the grip-rolls by turning the same by hand, yet it is often advantageous to
open the rolls, in order to straighten up the plies, previous to the attachment of the
web to the rolling up board; and to accomplish this opening movement, the upper
roll V is to be forced downward, thus compressing the springs o and depressing the
sliding boxes m, so as to allow the said upper roll to be carried out of its bearing
g to the holding rest as shewn by the broken lines in figure 3, and a reverse
movement will carry the roll V' back to its former position in close contact with the
lower roll V.
