IMPROVED MACHINERY APPARATUS FOR PRODUCING PLEATED OR GOFFERED FRILLING AND TRIMMING
Year: 1884

page_text: I, WALTER LOWE, of the Firm of Lowe and Johnson, of Poplar Works,
Poplar Street in the town and county of the town of Nottingham, Machinists do
hereby declare the nature of my invention for "IMPROVED MACHINERY
APPARATUS FOR PRODUCING PLEATED OR GOFFERED FRILLING AND TRIMMING,
to be as follows:-
AND
Each machine consists of the following parts namely, two standards connected
by tie rods, and carrying bearings for a pressing roller which is heated by gas and
air jets in the usual way, below the pressing roller is a pair of vertical bladed
pleating or goffering chains, capable of being adjusted to or from each other, the
front end of these chains are closely in gear with each other, and the back ends are
sufficiently far apart to allow the blades to gradually disengage from each other
thereby avoiding distortion of the material shaped by the blades. The chains are
driven simultaneously by toothed wheels secured on one pair of their axles, one of
the axles is provided with a bevelled toothed wheel, driven by a bevelled toothed
wheel on a separate shaft provided with a toothed, wheel gearing into a pinion wheel
on a driving shaft which also carries a toothed wheel gearing into another wheel on
the axle of the pressing roller which slowly revolves as the chains pass under it, the
chains pass over a plate, heated by gas and air jets. In front of the pressing roller
is a guide through which a foundation band of net or other fabric is passed, below
this guide is a second one which conducts the lace, muslin, cloth, or other fabric to
the pleating or goffering chains, between the guides when required a cotton thread
or threads, moistened with a solution of gum or equivalent cement, is or are passed,
which with the band, and other fabric is firmly pressed and cemented together, and
leaves the back of the machine in vertical parallel pleats or goffers, and in slightly
inclined planes horizontally.

page_text: Figure 1 shows a plan of my improved machinery and apparatus.
Figure 2 shows a view at the right side of the machine and
Figures 3 to 6 portions of the same severally referred to hereafter The
corresponding parts in each Figure are indicated by the same letters where
necessary Each machine consists of two side standards connected by an upper tie
bar A and two lower tie bars B. The standards carry bearings for a pressing roller C
which is heated by gas and Air jets in the usual way, conveyed to the interior of
the roller by a supply pipe C¹ the pressing roller instead of revolving parallel to
the side standards revolves at an angle thereto which prevents the material passed
under it by the vertical bladed chains from being distorted. The pressure of the
roller upon such material is regulated by thumb screws A' passed through the tie
bar A which force down plates, sliding in the standards each plate has a coiled
spring A interposed between it and the bearing below it. Below the pressing
roller is a pair of vertical bladed pleating or goffering chains D capable of being
adjusted to or from each other at their front end by screws passed through the
sides of slotted bearing plates D1 D2 actuating bearings through which chain driving
shafts are passed, these bearin's are not shown in the drawings but are of the same
form as the bearings D³ which slide in slots in the direction of the length of the
chains in the bearing plates D¹ D³ at the back of the machine being actuated by
screws D by which the requisite tightness is given to the chains, the front end of
the chains are closely in gear with each other and the back ends are sufficiently
far apart to allow the blades to gradually disengage from each other, thereby
avoiding distortion of the material shaped by the blades. The chains are driven
simultaneously by two toothed wheels E (one of which is shown at Figure 2)
secured on the front pair of axles, one of the axles is provided with a beveled
toothed wheel shown by dotted lines at Figure 2 driven by a beveled toothed
wheel E' carried by a toothed wheel E' which revolves on an axle secured in the
standard at the left of the machine the wheel E' is driven by a wheel E³ secured
on the driving or handle shaft E, the left end of the driving shaft carries a toothed
wheel E gearing into a larger wheel on the left end of the axle of the pressing
roller before named, such arrangement of gearing causes the pressing roller to slowly
revolve as the chains pass under it.
One of the axles for driving the chains is shown in side view at Figure the
upper end of both axles at the front of the machine have each a grooved and
flanged driving boss F secured on it the flange of which is recessed to receive the
axle pins which connect the links of the chain together one such flanged boss is
shown in plan at Figure 4 at Figure 3 one vertical bladed link of a chain and
driving boss are shown in the relative position they occupy when at work.
The links of the chain at the right side of the machine are of the shape shown
in side view at Figure 3 and the links of the chain at the left side of the machine

page_text: are of the shape shown in plan and side view at Figures 5 the links of both chains
are connected by axle pins and flat links one of which is shown in plan at Figure 6.
The chains as they are revolved pass over a plate G which is heated by gas and air
jets supplied through a pipe C¹, the plate G is supported by studs above the bearing
plate Di
The wheel E³ secured on the driving shaft carries a wheel E' which gears into a
toothed wheel above it which is secured on a short shaft H provided at its right
end with a grooved gathering wheel this wheel as it revolves draws the material
fed to the machine through a suitable shaped guide in front of the machine this
guide is provided with a wire which lies in the groove of the gathering wheel and
assists in conducting the lace, muslin, cloth or other fabric to the pressing roller and
chains.
The driving shaft at the right of the machine carries a toothed wheel like the
wheel E at the left such wheel is one of a train of wheels which cause a short
shaft H to revolve, this shaft at its left end carries a small gathering wheel
shown at Figures 1 and 2 by dotted lines under the guide in front of the machine,
and between this guide and the pressing roller a guide I conducts a cotton thread
or threads moistened with a solution of gum or equivalent cement to the material
passing under the roller the portion of fabric projecting above the chains is turned
down on the top ends of the links by the pressing roller the moisture from the
cotton thread or threads firmly cementing both together the fabric leaves the back
of the machine in the form of vertical pleats or goffers projecting from a narrow
flat band.
By employing chains with links of the form shown in the drawings lace, muslin,
cloth or other fabric which has previously been pleated or gophered across its width
may be made up in my Improved machine into other pleats or goffers without
distorting the pleats or goffers previously formed on the fabric."
Having now particularly described and ascertained the nature of my Invention
and in what manner the same is to be performed I declare that what I claim is
the construction and employment of a pressing roller in combination with vertical
bladed chains in a frilling machine substantially as described and illustrated in the
Drawings annexed.
