PROVEMENTS IN FEEDING AND COMPRESSING MECHANISM FOR

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN FEEDING AND COMPRESSING
MECHANISM FOR CARDING ENGINES." [A communication from abroad by John
Abbott, of Philadelphia, Pennsylvania, United States of America.]
This Invention relates to devices for automatically feeding the sliver as it comes
from one card to the next card, and compressing it while on the way.
The said Invention comprises the combination with a pair of calender rolls and
an endless carrying belt of a feeding plate vibrating in the direction of the move-
ment of said belt, a crank-shaft, and operating mechanism.
In carrying the said Invention into practice I provide a bed-plate which supports
a forward pair of standards and a rear pair of standards. These standards are con-
nected on each side by inclined beams, which extend upward from the lower ends
of the rear standards to the upper ends of the forward standards. The upper ends
of the rear standards are provided with forwardly extending horizontal bars or
arms, and the lower ends of said rear standards are provided with horizontal
longitudinally adjustable rearwardly extending arms. The aforesaid standards,
beams, and arms constitute the framing of the said improved feeding and pressing
devices or mechanism.
As the sliver is removed from the doffer or front of the first card it is received
by a broad flat plate, which is journalled at its upper end by a transverse rod to
bearings on the top of the said forward arms. The said plate extends almost
entirely across the space between the said arms, and is turned up at its edges so as
to form a broad shute with flanged or protective sides. The said plate or shute is
[Price 6d.]

page_text: operated by mechanism hereinafter described, so as to alternately occupy a position
slightly inclined upward and backward from a vertical plane. When in the former
position it begins laying on the upper part of an inclined carrier or endless travelling
belt which is arranged below said plate, and the latter continues laying down along
the incline of said carrier until the most rearward point of its vibration is reached.
It then rocks forward and upward again to its first position, doubling the sliver;
this action is constantly repeated, so that there is a continuous doubling feed of the
sliver. The simplicity of construction of the operating parts and the directness of
their action ensure a smooth and even sliver, and the forward movement of the
carrier tends to prevent any strain on the fibre of the sliver during the doubling at
the lower end of the vibration of the plate. The carrier delivers the sliver to a
pair of compressing calender rolls, which compress the doubled sliver before allowing
it to pass the feed-rolls of the next card. These calender rolls are journalled in the
upper part of the forward standards. The carrier is provided with two rolls, the
upper one of which is journalled in the aforesaid inclined beams a little behind and
below said calender rolls, while the rear roll is similarly journalled in the rear ends
of the said rearward arms. These arms are provided with longitudinal slots and
clamp-screws, which allow said arms to be adjusted backward or forward longi-
tudinally, so as to tighten or loosen said carrier or travelling belt at pleasure.
The vibratory motion of the plate or shute is communicated by a rotating crank-
shaft through a connecting rod, which has a hinged connection to a bracket on the
back of said plate. This shaft, as well as that of the driving calender roll and
the lower carrier-roll, is provided with a pulley or belt-wheel operated by a suitable
belt.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. IMPROVEMENTS IN FEEDING AND COMPRESSING
MECHANISM FOR CARDING ENGINES." A communication from abroad by John
Abbott, of Philadelphia, Pennsylvania, United States of America.
This Invention relates to devices for automatically feeding the sliver as it comes
from one card to the next card, and compressing it while on the way.
The said Invention comprises the combination with a pair of calender rolls and
an endless carrying belt of a feeding plate vibrating in the direction of the move-
ment of said belt a crank shaft and operating mechanism.
In the accompanying Drawing,
Figure 1 is a perspective view of my improved feeding device and the adjacent
parts of the machine; and
Figure 2 is a vertical longitudinal section through the same.
Similar letters indicate corresponding parts in both Figures.
A represents the bed plate of the machine, which supports a forward pair of
standards B, B, and a rear pair of standards B¹, B¹. These standards B, B¹, are
connected on each side by inclined beams B2, which extend upward from the lower
ends of the rear standards B¹ to the upper ends of the forward standards B. The
upper ends of the rear standards B' are provided with forwardly extending horizontal
bars or arms b, and the lower ends of said rear standards are provided with
horizontal longitudinally adjustable rearward extending arms 63. The aforesaid
parts B, B1, B2, b, and 62, constitute the framing of my improved feeding and pressing
devices or mechanism.
As the sliver is removed from the doffer or front of the first card it is received by
a broad flat plate C, which is journalled at its upper end by a transverse rod c in
bearings on the top of the arms b. The said plate extends almost entirely across
the space between the said arms, and is turned up at its edges c¹ so as to form a
broad shute with flanged or protective sides. The said plate or shute C is operated
by mechanism hereinafter described, so as to alternately occupy the position shewn
in Figure 2. When in its forward position it begins laying the sliver on the upper
part of an inclined carrier or endless travelling belt D, which is arranged below the
plate C, and the said plate continues laying down the sliver along the incline of
said carrier until the most rearward point of its vibration is reached. It then rocks
forward and upward again to its first position, thereby doubling the sliver. This
action is constantly repeated, so that there is a continuous doubling feed of the
sliver. The simplicity of the construction of the operating parts, and the directness
of their action, ensure a smooth and even sliver, and the forward movement of the
carrier tends to prevent any strain on the fibre of the sliver during the doubling at
the lower end of the vibration of the plate C. The carrier D delivers the sliver to
a pair of compressing calender rolls E, which compress the doubled sliver before
allowing it to pass the feed-rolls of the next card. These calender rolls are journalled
in the upper part of the standards B, B. The upper roll d of the carrier D is
journalled in the side beams B² a little behind and below said calender rolls, while
the rear roll d¹ of said calender is similarly journalled in the rear ends of the arms b³
hereinbefore referred to. These arms 62 are provided with longitudinal slots 6³ and
clamp screws 64, which allow said arms to be adjusted backward or forward
longitudinally, so as to tighten or loosen said carrier or travelling belt D as
desired.
The vibratory motion of the plate or shute C is communicated to it by a rotating
crank shaft F through a connecting rod f, which has a hinged connection to a
bracket f¹ on the back of said plate. This shaft, as well as that of the driving

page_text: calender roll and the lower carrier roll, is provided with a pulley or belt wheel
operated by a suitable belt. These pulleys and the belt operating them need no
particular description.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,
First. The carrier in combination with the plate C vibrating in the direction of
the motion of the said carrier, substantially as and for the purpose set forth.
Second. The calender rolls, the carrier, and the plate C, in combination with the
crank shaft, the connecting rod, and the operating mechanism of the said carrier
and rolls, substantially as and for the purpose specified.
Third. The flanged plate C in combination with the crank-shaft, the connecting
rod, and the said operating mechanism, substantially as and for the purpose set
forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Fifth day of February, in the year of our Lord One
thousand eight hundred and eighty.
