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

page_text: I JOHN CROMPTON of Farnworth near Bolton in the County of Lancaster,
Overlooker, do hereby declare the nature of my Invention for "IMPROVEMENTS IN
SECTION BLOCKS AND PRESSERS FOR SECTIONAL WARPING AND
BEAMING
MACHINES," to be as follows:-
This invention relates to sectional warping and beaming machines, and has for
its object the attainment of varying the widths of the sections on which the yarn
is wound, together with means for effecting the same operation to the presser
blocks, and the application of one set of sections to any width of weavers beams.
Under the present system each of the sections of the warp contain the same
number of warp threads, whereby a certain number of whole patterns and a fraction
have to be run at a time, which necessitates the changing of a number of warp
threads from one side of the creel and reeds to the other side at the commencement
of each section in order to join up the pattern; and further several sets of different
widths are required corresponding to the number of the sections on which the warp
is made.
My invention has for its object the simplification of the process of warping, by
which any number of warp threads according to the pattern being warped can be
run at one and the same time, the sections being fixed or set in width proportional
to the number of whole patterns assigned to each, by which only one set will be
necessary as they may be expanded or contracted and fixed to the various widths
required, being applicable to any width of weavers beams.
I effect my invention by making the centre portion of the section block for
receiving the yarn in several parts of wood (by preference) or of other suitable
materials, with means for adjusting the width as desired, by forming the circular
expanding section block with circular ends, on the outer edge of which are secured
by suitable means several projecting claws or arms of varying lengths, forming a
circular barrel or surface for receiving the yarn, being placed between the ordinary
side flanges on the section shaft. The outer or circular ends of the centre portion
of the section block for receiving the yarn are provided with centre holes, one side
having a right hand thread, and the opposite side a left hand thread, or by
[Price 6d 1

page_text: supplying them with metallic bushes or bosses provided with screws or threads to
receive a metallic bush, on the outside of which is formed corresponding right and
left hand screws.
This bush is placed on the ordinary shaft on the warping or beaming machine
for carrying the section blocks, being secured by convenient means to allow of its
easy removal or adjustment on the shaft when required.
In case it is desired to increase the width of the section, the block is expanded
lateral'y in a simple manner by operating the centre screwed bush on the carrying
shaft, or by turning the outer rim or barrel of the section itself, when by the
action of the right and left hand screws on its outer surface, each half of the
section block opens out or recedes from each other; being locked in position by
convenient means.
When the section is expanded, openings are formed on the rim of the section
block, between the ends of the long and short claws or arms, which might be found
detrimental, in which case I cover each half of the section block with suitable
materials, such as, sheet metal, sheet brass, or other equivalents, one side being made
to slide under or over the other.
In case the section block is required to give a greater width than originally
intended, it is accomplished by placing suitable loose distance pieces between the
ends of the projecting claws or arms.
In commencing to warp upon my improved section block, the yarn is booked on
or to in such a manner by suitable means, that when the operation of winding
cominences the pull of the yarn is in the same direction as that required to expand
the section block, thereby locking it between the ordinary face plates, set and fixed
on the section shaft.
According to the present arrangement of pressers for section blocks used in
connection with sectional warping and beaming machines, I find that my invention
would be useless, therefore to overcome the difficulty and make the same useful and
practicable, construct the circular presser in a similar manner to my improved
expanding section block herein before described, by which application it can be
regulated in width to meet the varying requirements, being held or supported in
the usual manner by the ordinary appliances.
Dated this second day of January 1884.

page_text: I JOHN CROMPTON of Farnworth near Bolton in the County of Lancaster,
Overlooker, do hereby declare the nature of my Invention for "IMPROVEMENTS IN
SECTION BLOCKS AND PRESSERS 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 :-
This invention relates to sectional warping and beaming machines, and has for
its object the attainment of varying the widths of the sections on which the yarn
is wound, together with means for effecting the same operation to the presser
blocks, and the application of one set of sections to any width of weavers beams.
Under the present system each of the sections of the warp contain the same
number of warp threads, whereby a certain number of whole patterns and a fraction
have to be run at a time, which necessitates the changing of a number of warp
threads from one side of the creel and reeds to the other side at the commencement
of each section in order to join up the pattern; and further, several sets of different
widths are required corresponding to the number of the sections on which the warp
is made.
My invention has for its object the simplification of the process of warping, by
which any number of warp threads according to the pattern being warped can be
run at one and the same time, the sections being fixed or set in width proportional
to the number of whole patterns assigned to each, by which only one set will be
necessary as they may be expanded or contracted and fixed to the various widths
required, being applicable to any width of weavers beams.
In order that this my said invention may be more readily seen and fully
understood so as to be carried into operation, I have hereunto annexed drawings
illustrative of my improvements, reference being made to the figures and letters
marked thereon.
A is the section shaft of the Beaming and Warping Machine; B the ordinary side
flanges. The centre portion of the expanding section block C for receiving the
yarn is made in several parts of wood (by preference) or of other suitable materials.
The circular ends D are provided with the projecting claws or arms E as shewn in
Figs. 1 to 6, being of the section shewn in Fig. 4; the outer surface or periphery
forming a circular barrel to receive the yarn. To the circular ends D are fixed the
metallic bushes or bosses F provided with the right and left hand female screws in
which are placed the metallic bush G on the outside of which is formed
corresponding right and left hand screws. This bush is fitted with a key or
feather to correspond with the key way or bed in the section shaft A of the
Beaming and Warping Machine. Fig. 1 is a section of my improved section block
when non-expanded.
In case it is desired to increase the width of the section Cit is expanded laterally
by operating the centre screwed bush G on the section shaft A, or in a more simple
manner by turning the periphery or barrel of the section which will operate the
centre screwed bush G, when each half of the section block will recede from each
other to the desired width, which is obtained by setting the side flanges B
beforehand and operating the expanding block until it locks itself between them,
which can be performed accurately and instantly as shewn in Fig. 2.
In case the section block is required to give a greater width than the length of
the claws or arms, it is opened or expanded as in Fig. 3, the distance or opening
between the projecting claws or arms E being filled by the loose distance pieces H.
When the section is expanded, the openings I are formed in the rim or
periphery between the ends of the projecting claws or arms E as shewn in Figs. 2,
5, and 6. In some cases these openings might be found detrimental, which is

page_text: overcome by providing the periphery with the casings J composed of thin metal or
other suitable materials, being secured to each half and one side is made to slide
over the other in a telescopic form.
To prevent the section block being altered after it is set to the desired width
between the side flanges B, it is firmly secured by the setting screw K. shewn in
Fig. 1, the latter operating on the screwed bush G or the shaft A.
In commencing to warp, the ends of the yarn are tied together in a knot, which
is placed through the hole a, and into the slot b, provided for the purpose in one of
the claws E, as in Fig. 5, the slot being placed in the direction to expand the
section block, thereby locking it between the side flanges B.
It is obvious that to simplify the construction and reduce the cost of manufacture
so as to make them saleable, at the same time being an easy method of converting
existing sections into expanding ones, they can be made as shewn in Fig. 10, which
is performed by placing the right or left hand screw G on the section shaft A, as
aforesaid, and providing the section with the female bush F to work on the screw G.
On the end of the screwed bush G is turned the plain end E², on which is mounted
the circular end E', and secured by the washer E³. The opening or distance formed
between the section block E and the end E' is compensated for by the sheet metal
.cover J, which cover is secured to the circular end E', thus sliding on the
section E; the metallic cover J covers the entire surface of the section block when
non-expanded.
In making my invention useful and practicable it is necessary that the circular
presser must be capable of being expanded, which can be made in a similar manner
to the expanding sections shewn in Figs. 1, 2, and 3, where large pressers are
employed. In machines where the diameter of the presser is limited, it is formed
of suitable metallic or other materials, with the circular ends M provided with the
projecting claws or arms N and O, constructed in an helical form as in Figs. 7
and 8, which can be expanded by simply pulling the circular ends asunder as in
Fig. 7, at the same time presenting a perfectly even surface to the yarn it is
operating against, as through line W. X.
Fig. 8 is an outside view of the presser when non-expanded, and Fig. 9 is a
section of the presser through line Y. Z, the same being held or supported by the
presser lever P and set screw P¹.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is
1st The use and construction of expanding section blocks and pressers employed
with Sectional Warping and Beaming Machines, operated and applied substantially
as and for the purposes herein set forth and described and shewn on the drawings
in Figs. 1 to 6.
2nd The use and construction of expanding section blocks for the purpose set forth
and described, and as shewn on the drawings in Fig. 10.
3rd The use and construction of expanding pressers employed with Sectional
Warping and Beaming Machines, consisting of the circular ends M and the projecting
claws or arms N and O, with the sliding edges in the form of an helical screw or its
equivalent, by which they are expanded, substantially as described and shewn on
the drawings in Figs. 7, 8 and 9.
