PROVISIONAL SPECIFICATION.
Improvements in the Construction of Flanges, suitable for Weavers'
Warp Beams and the like.
We, THEOPHILUS HANSON, of 20, Northcoat Terrace, Undercliffe, Bradford,
in the County of York, Engineer, and JOSEPH STEEL, of Harden, near Bingley,
in the said County, Spring Manufacturer, do hereby declare the nature of this
invention to be as follows:
This invention relates to certain improvements in flanges suitable for weavers'
warp beams, and has for its object the construction of the same in such a manner
that, the weight of the flange is considerably reduced, an increase of strength
obtained, and the flanges not so liable to be broken as when constructed as hitherto ;
also to mount them in such a manner that they are applicable to various sizes
of beams.
We accomplish our object by forming the flanges of steel or other suitable
material formed circular with a hole in the centre and the flat surface of the
flange corrugated, the circumference of the flange is strengthened by bending the
plate over so that it is double, or a wire may be inserted therein.
The hole in the centre of the flange may be cut clean away, or the metal from
the hole may be bent so as to form clips to fasten the flange on the beam, or
secured to clips made in halves and connected together by left and right hand
threaded screws; that on turning the screws, the clips are operated so as to expand
or contract for liberating or securing the flange to the weavers' warp beam.
A flange at right angles to the corrugated plate may be formed around the centre
hole, by which the flange may be secured to the weavers' warp beam, or the flanges
may be made of malleable or other suitable metal with corrugations formed on the
flat surface of the flange.

Improvements in the Construction of Flanges, suitable for Weavers'
Warp Beams and the like.
We, THEOPHILUS HANSON of 20, Northcoat Terrace, Undercliffe, Bradford,
in the County of York, Engineer, and JOSEPH STEEL, of Harden near Bingley
in the said County, Spring Manufacturer, do hereby declare the nature of this
invention 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 certain improvements in flanges suitable for weavers'
warp beams, and has for its object the construction of same in such a manner that,
the weight of the flange is considerably reduced, an increase of strength obtained,
and the flange not so liable to be broken as when constructed as hitherto, also
to mount them in such a manner that they are applicable to various sizes
of beams.

page_text: We accomplish our object by forming the flange, circular, of steel or other
suitable material with a hole in the centre, and having the flat surface indented or
corrugated; the circumference of the flange is strengthened by turning the edge
down to the outside.
The flange is secured to a hinged clamp, preferably of malleable iron, by which
means the flange is secured to the warp beam.
In order that our invention may be fully understood, we will describe the same
in detail by making reference to the accompanying sheet of drawings in which
Fig. 1 represents a back view of our improved flange.
Fig. 2. a section on line a. b.
Fig. 3 a plan view of boss or clamp with part of flange in section and
Fig. 4 a detail of a detached clamp.
The flange is indicated by the letter A. having a number of indentations or
corrugations B. formed thereon; the periphery of flange is turned down at C: for
the purpose of adding strength and giving a smooth surface on the inside circum-
ference, thereby reducing the liability of the warp ends catching and being damaged
thereby.
The clamp D. is formed in two parts and hinged at E. by hinge pin F. which
passes through the flange A. the pin head is counter sunk therein. The free ends
or lugs G. G. of the clamp D. are secured together by a bolt and nut H. or in any
convenient manner. The flange A. is further secured to the clamp, by means of a
second pin J. similar to the hinge pin F. both of which are provided with a
threaded nut on the end protruding through clamp for nipping the latter to the
flange.
Upon placing the flange on the beam in the required position, it may be securely
held, by tightening the bolt and nut H. the pins E. and J. are then tightened up,
thereby firmly securing the flange A. to the clamp D.
When the lugs G. G. of two parts forming the clamp D. are close together, the
aperture through the centre of clamp is not cylindrical, that is to say, it is larger
in diameter from the points c to d than from e to f, thus by fitting flanges with
clamps as before described, allowance is provided for beam shrinkage, and may
be used on beams varying in diameter, say for example to the extent of half
an inch.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is,
1. The construction of warp beam flanges A. strengthened at the circumference C.
and indented or corrugated at B. on the flat surface substantially in the manner as
shown and described.
2. Warp flanges A. combined with clamps D. hinged at one end and secured
substantially in the manner described.
