MANGLING MACHINES."
"IMPROVEMENTS IN
My Invention consists in constructing mangling machines as herein-after described,
with two pairs of mangling rollers working in the same direction, and with means
for carrying the work, or for receiving and holding the work while passing from
the first pair of rollers to the second.
In constructing my improved machine I mount on the driving shaft (which may
be driven by hand or other power) a toothed pulley, which gears with a wheel; on
the shaft of this wheel is another pulley, which gears with a wheel on the shaft of
one of the rollers of each pair. The motion may be transmitted to the other roller
of each pair by toothed or frictional gearing.
Between the two pairs of rollers I place a receiver, the object of which is to take
the work as it leaves the first pair of rollers and conduct it to the second pair. This
receiver may be in the form of slides, composed of upper and lower boards, extending
from one pair of rollers to the other, and with sufficient space between them for
the work.
Or, instead of slides, I employ a pair of small rollers, between which
the work is received as it leaves the first pair of rollers, and which guide it to the
second, pair.T

MANGLING MACHINES."
"IMPROVEMENTS IN
My Invention consists in constructing mangling machines as herein-after described,
with two pairs of mangling rollers working in the same direction, and with means
for carrying the work, or for receiving and holding the work while passing from
the first pair of rollers to the second.
In constructing my improved machine I mount on the driving shaft (which may
be driven by hand or other power) a toothed pinion, which gears on a wheel; on
the shaft of this wheel is another pinion, which gears with a wheel on the shaft of
one of the rollers of each pair. The motion may be transinitted to the other roller
of each pair by toothed or frictional gearing.
Between the two pairs of rollers I place a receiver, the object of which is to take
the work as it leaves the first pair of rollers and conduct it to the second pair. This
receiver may be in the form of a guide composed of upper and lower boards, extend-
ing from one pair of rollers to the other, and with sufficient space between them for
the work. Or, instead of boards, I employ a pair of small rollers, between which
the work is received as it leaves the first pair of rollers, and which guide it to the
second pair.
The accompanying Drawings represent a mangling machine constructed according
to my Invention, Figure .1. being a front elevation; Figure 2, an elevation of the
end A; Figure 3;'an elevation of the end B; and Figure 4, a transverse section
at C.
a is the driving shaft, provided with fast and loose pulleys b, b, for the belt, or
this shaft may be driven by a crank handle; c is a pinion on the shaft a, and gearing
with a wheel d, on the shaft, of which is another pinion e. This last-named pinion
gears with two wheels f, g, mounted respectively on the shafts of the lower
roller h, i, of each pair of mangling rollers; h¹,, are the upper rollers of each
pair; they are driven from the lower rollers by means of toothed gearing k, k.
1, 1, are a pair of small rollers between the two pairs of mangling rollers. As tho
work leaves the first pair of mangling rollers h, h¹, the small rollers 1, l', receive it,
and guide it to the second pair i, ¹. The rollers ; ; are driven by an endless chain
at m, Figure 2, which passes over grooves in the lower rollers 1, i, and in the
roller, the groove either in the roller h or in the roller i being in the form of a
chain wheel. Instead of the rollers 1, 1, a receiver, composed of an upper and a
lower horizontal board, may be employed. These boards are sufficiently far apart
to allow the work to pass readily between them, and they extend from the
rollers h; h, to the rollers i, 2, and form a guide or slide to conduct the work from
one pair of mangling rollers to the other.
The other parts of the machine will be understood without further explanation..
And having now. described the nature of my said Invention, and in what manner
the same is to be performed, I declare that I claim, constructing mangling machines
with two pairs of mangling rollers working in the same direction, and with means
for carrying the work, or for receiving and holding the work while passing from
the first pair of rollers to the second, substantially as herein-before described.
In witness whereof, I, the said Ralph Barnett, have hereunto set my hand
and seal, this 23rd day of January, One thousand eight hundred and
seventy-nine.
