IMPROVEMENTS IN SECTION BLOCKS FOR SECTIONAL WARPING AND BEAMING MACHINES
Year: 1884

page_text: We, JOHN CHRISTMAS SEWELL Manufacturer EUSTACE HULTON, Manufacturer
and JOHN BETHEL Mill Manager all of the Moseley Mills Pendleton in the County
of Lancaster do hereby declare the nature of our invention for "IMPROVEMENTS IN
SECTION BLOCKS FOR SECTIONAL WARPING AND BEAMING MACHINES" and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
These Improvements relate to the Section blocks employed in conjunction with
Sectional Warping and Beaming Machines and have for their objects to secure
greater durability, to give greater facilities for warping large or small patterns or
Farts of patterns in the same warp and to reduce the cost of maintaining the
requisite stock or plant of blocks.
In order that our Invention may be fully understood and more readily carried
into practical effect we have hereunto appended a sheet of Drawings marked with
letters of reference similar letters indicating similar parts in the various figures.
Figs. 1, 4 and 5 are side elevations, Fig. 2 is a longitudinal section, Fig. 3 is a
transverse section through X. Y of Fig. 2 and Fig. 6 is a transverse section through
X. Y Fig. 5 of section blocks to which our Improvements have been applied.
Section blocks made under these Improvements may be non-expanding as shewn
in elevation in Fig. 5 and in Section in Fig. or they inny be made expanding or
telescopic for the purpose of facilitating the warping of large or small patterns or
parts of patterns in the same warp as shown in elevation in Figs. 1 and 4 and in
Section in Figs. 2 and 3.
-
The Section block A may be of wood, metal or other suitable material. Across
its periphery we form a groove or recess B. This recess may either be parallel to
the axis of the block as shown in Fig. 1 or it may be at any angle thereto as
indicated in Fig. 4. Around the periphery of the block A. there is placed a freely
fitting cylinder C or C₁ of thin metal or other suitable material. When the
telescopic or expanding arrangement is not required the Cylinder C' may occupy
nearly the whole width of the section block as shown in Fig. 5. If the expanding
arrangement is desired the Cylinder C is made of sufficient length or width to allow

page_text: it to slide freely to and fro upon the surface of the block after the manner of the
slide of a telescope and to the extent of the amount of expansion or of additional
length that may be required.
In the Cylinder C or C there is also formed a groove or recess D corresponding
to and loosely fitting into the recess B formed upon the periphery of the Section
block.
.
In the expanding arrangement one end of the cylinder C may project beyond
the section block A the projecting end being mounted upon or attached to the disc
or end piece E Fig. 2. The disc E is then concentric with the section block and
has a hole F formed in its centre for the passage of the section shaft, the hole
having the same diameter as or being larger than the diameter of the section shaft.
This disc however is not essential and may be dispensed with nor is it essential
that the sliding cylinder should in that case project beyond the block.
Through the bottom of the recess D in the cylinder C or C¹ there are formed one
or more small holes for the passage of the screw G which engages in the nut or
tapped plate H or H¹ Figs. 2, 3 and 6. In the expanding arrangement the screw G
and the nut or plate H move with the sliding cylinder C, in the non-expanding
arrangement the nut is attached to the block at the bottom of the recess as
shown at H Fig. 6. In the expanding arrangement also the bottom of the
recess B is provided or has formed in it a slot K which permits the screw G to
traverse it longitudinally to the required extent the sliding nut H being below the
slot. The bolt or screw G is inserted through the hole or one of the holes in the
bottom of the recess of the cylinder C and engages with the fixed nut H' or
the sliding out H.
Under the head of the screw or bolt G there is placed a washer or plate L the
end or ends of which may be cranked or bent upwards and forwards as shewn in
Fig. 2. This plate by preference has its end or ends tapered to a point and serves
the double purpose of giving the screw head a greater gripping surface and of
enabling the yarn to be secured to the section block by its means without the usual
knot hole being made therein.
By tightening the screw G in its nut the recessed portion of the cylinder C or C'
is forced downwards into the recess of the section block. The cylinder is thereby
stretched or put under tension and caused to firmly grip the periphery of the
section block.
With the expanding arrangement when it is desired to expand or contract the
surface of the block for a larger or smaller pattern or portion of pattern of warp
the screw G is loosened whereupon the Cylinder C may be adjusted to the
desired position and the screw be tightened thus securing the cylinder in the new
position.
The recessed cylinder C¹ in the non-expanding arrangement Figs. 5 and 6 may
be omitted but we prefer to use it in all cases. In the expanding arrangement the
slot K instead of being formed in the bottom of the recess B of the Section block
may be formed in the bottom of the recess in the cylinder when_the_sliding
nut His dispensed with and a fixed nut may be used as shown at H¹ Fig. 6.
Having thus described the nature of this our said Invention and the best
means known to us for carrying the same into practical effect we desire it to be
understood that we do not limit ourselves to the precise details as these may be
varied without departing from the Invention but that what we claim is :—
First The adaptation or application to section blocks employed with Sectional
Warping or Beaming Machines of the recessed Cylinder C₁ in combination with
the screw G, the fixed nut H¹ and the plate or hook L all substantially as and for
the purposes herein before set forth and described and as illustrated in Figs. 5
and 6 of the accompanying Drawings.
Second. The adaptation or application to section blocks employed with Sectional
Warping or Beaming Machines of the recessed cylinder C capable of sliding upon
the recessed section block and of being fastened in position by means of a screw

page_text: and nut in combination with the plate or hook L substantially as and for the
purposes hereinbefore set forth and described and as illustrated in Figs. 1, 2, 3
and 4.
Third. The combination of the screw G the plate or hook L and the fixed nut H¹
substantially as hereinbefore set forth and described.
