IMPROVEMENTS IN WEAVING, AND IN APPARATUS CONNECTED THEREWITH
Year: 1876

page_text: LETTERS PATENT to Benjamin Berry, Machine Maker, of Harris Street,
Bradford, in the County of York, for the Invention of " IMPROVEMENTS IN
WEAVING, AND IN APPARATUS CONNECTED THEREWITH."
PROVISIONAL SPECIFICATION left by the said Benjamin Berry at the Office
of the Commissioners of Patents on the 9th August 1876.
BENJAMIN BERRY, Machine Maker, of Harris Street, Bradford, in the County of
York. "IMPROVEMENTS IN WEAVING, AND IN APPARATUS CONNECTED THERE-
WITH."
My Invention relates to employing a self-acting apparatus for lowering the piece
beam as the weaving operation takes place, allowing for the rolling or lapping of
the fabrics on to the picco beam; also enabling the lowering of the piece beam from the
nipping surface of the driving or taking up beam during the operation of pulling back.
or arranging the fabrics, doing away with all weights and levers heretofore in use;
for this purpose on the inside of the loom frames are fitted inetal tubular sockets,
in which work springs and rods. On the top of the rods are fitted bearing caps,
the bottom parts forming the shoulders or bearings of the springs; the top parts
are made curved to fit the ends of the piece beam shaft or journals. As the weaving
operations proceed, and the weight increased by the rolling or lapping of the fabrics
on the piece beam, the rods and springs are forced in the tubular sockets, keeping
the fabrics to the nipping surface of the driving or taking up beam.
On the front of the tubular sockets are cast racks, in which work pawls fitted in
lugs formed on the front of the bearing caps; these racks and pawls are for keeping
the piece beam down and in position during the operation of pulling back when
the fabrics beconie disarranged; for this purpose on the inside of the loom frames
and above the tubular sockets are fitted studs forming fulcrums for a lever, which
the operative uses for forcing down the piece beam from the nipping surface of the
driving or taking up beam. The pawls are then let down and gear in the teeth of
the racks, securing the beam in position during the operation of pulling back.

are lifted out of gear, and the piece beam springs up into working position.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Benjamin Berry in the Great Seal Patent Office on the 5th February
1877.
BENJAMIN BERRY, Machine Maker, of Harris Street, Bradford, in the County of
York. "IMPROVEMENTS IN WEAVING, AND IN APPARATUS CONNECTED THERE-
WITH."
The said Invention relates to employing a self-acting apparatus for lowering the
piece beam as the weaving operations take place, allowing for the rolling or lapping
of the fabrics on to the piece beam; also allowing of the lowering of the piece
beam from the nipping surface of the driving or taking up beam during the
operation of pulling back or arranging the fabrics, doing away with the weights
and levers heretofore in use; for this purpose on the inside of the loom frames are
fitted metal tubular sockets, in which work springs and rods. On the top of the
rods are fitted bearing caps, the bottom parts forming the shoulders or bearings of
the springs; the top parts are made curved to fit the ends of the piece beam shaft
or journals. As the weaving operations proceed, and the weight increases by the
rolling or lapping of the fabrics on the piece beam, the rods and springs are forced
in the tubular sockets, keeping the fabrics to the nipping surface of the driving or
taking up beam.
On the front of the tubular sockets are cast racks, in which work pawls fitted in
lugs formed on the front of the bearing caps; these racks and pawls are for keeping
the piece beam down and in position during the operation of pulling back when the
fabrics become disarranged; for this purpose on the inside of the loom frames and
above the tubular sockets are fitted studs forming fulcrums for a lever which the opera-
tive uses for forcing down the piece beam from the nipping surface of the driving or
taking up beam; the pawls are then let down and gear in the teeth of the racks,
securing the beam in position during the operation of pulling back. Directly the
fabrics are arranged and ready to proceed weaving the pawls are lifted out of gear,
and the piece beam springs up into its working position.
But in order to enable these improvements to be better understood I will proceed
to describe the same by reference to the accompanying Drawing, in which Figure 1
represents a front elevation of a loom with my improved apparatus fitted thereto;
Figure 2, side elevation of a loom shewing sectional elevation of the apparatus;
and Figure 3, plan of the same.
Figure 4 represents a side view of the lever for lowering the piece beam from the
nipping surface of the driving or taking up beam.
Similar letters of reference are used in all the Figures to represent similar parts.
On the inside of the loom frame or frames A is or are fitted one or two self-acting
apparatus for lowering the piece beam as the weaving operations proceed; the
apparatus is constructed with a metal tubular socket B, which is bolted to the
frame A by the bolt C, which passes through the lug D cast on the socket B, and
through a regulating distance piece E, and through the frame; the distance piece E
varies in thickness to suit the loom, having the apparatus fitted to it. In the
tubular socket B works a spring F and a rod G; the rod passes through the spring
and through the bottom plate of the socket, and on the top of the rod is fitted a
bearing cap H, the bottom part I forming the shoulder or bearing of the spring;
the cap is curved to suit and fit the shaft or journal J of the piece beam K. As
the weaving operation proceeds the weight on the piece beam K increases by the
rolling or lapping of the fabrics forcing the spring F and rod G in the tubular
socket, the rod being forced through the socket. bottom, keeping the fabrics to the

page_text: nipping surface of the driving or taking up beam L. On the front of the socket B
is formed a rack M, in which works a pawl N; the top of the rack is forked,
forming lugs O, in which is fitted a lug P formed on the front of the bearing cap H.
The bottom Q of the pawl N works in the rack M, and keeps the piece beam K
down and in position during the operation of pulling back when the fabrics become
disarranged. To pull down the piece beam K a lever R formed with a hook S is
employed; the hook is passed over a stud T fitted to the loom frame, and the
back U of the lever presses on the shaft or journal J of the piece beam K. By
pulling the top V of the lever R the cap, rod, and spring are forced in the socket,
and the piece beaun K lowered from the nipping surface of the driving or taking
up beam L, and the pawl N is then let down and gears in the teeth W of the
rack M, securing the beam in position during the operation of pulling back. Directly
the fabrics are arranged and ready to proceed weaving the pawl N is lifted out of
gear, and the piece beam K springs up into its working position.
Having thus described my improvements, and the best means I am acquainted
with for carrying the same into effect, I would have it understood that I do not
confine myself to the precise details shewn and described, as these may be varied
without departing from the peculiar character of the Invention; but what I do
claim is, the construction and employment of a self-acting apparatus for lowering
the piece beam as the weaving operations proceed, and the employment of a hooked
lever to pull down the piece beam when the fabrics become disarranged, substan-
tially as herein-before described and represented in the accompanying Drawing.
In witness whereof, I, the said Benjamin Berry, have hereto set my hand
and seal, this Thirty-first day of January, in the year of our Lord One
thousand eight hundred and seventy-seven.
