Improvements in Flanges for Warpers' and Weavers' Beams and like
purposes.
I, THOMAS PRESCOTT, of Mount Pleasant, Sale, in the County of Chester,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows;-
-
This invention relates to an improvement in the construction of the metallic
ends of warpers' and weavers' beams and the like. The object of my invention
is to obtain a flange that will combine strength with lightness, and will have
a perfectly plain surface free from holes or bolt heads on the face side, or that
side which is next to the warp or material that is on the beam, no bolts passing
through, or bolt holes being required in said face side. In the accompanying
drawing I have shown a transverse section of my improved flange which I con-
struct by dishing a circular steel or iron plate as a thereby producing a rib or
web al on the outer edge of said plate. I form a hole e in the centre of the
plate by pressing the metal inwards, which forms a 1ib as a²; I place a block,
preferably of hard wood as bon said rib, and press down or hammer the edge g
so that said edge will grip the block b through which bolts may have been
previously passed. I press a steel or iron plate so as to produce a flattened
dome as f with the circumferential edge bent outwardly forming a rib or web
as j; I form a hole of the required size in the centre of the plate by pressing
the metal inwards, thereby producing a rib m, which I fit within the rib a²,
the bolts c or their equivalents passing through holes in the plate f, and the
outer rib fitting within the rib a¹. I screw up the nuts e, the two plates a
and being thereby firmly united; I rivet or otherwise join the ribs a¹ and j.
By these means a strong and light metallic flange is produced with a perfectly
plain surface without bolt holes or bolt heads on the face side. Any preferred
form of boss or collar for fixing the herein before described flange to the wood
or metal beam may be attached thereto by means of the projecting bolt ends
which are made sufficiently long and provided with an extra nut c². Additional
strength may be imparted to the outer edge of the herein before described flange
by grooving or chanelling either or both of the ribs a¹ and j. If the edge m¹
of the rib m is expanded after being placed within the rib a², coach screws may
be employed in place of the bolts c

purposes.
I, THOMAS PRESCOTT, of Mount Pleasant, Sale, in the County of Chester,
Mechanical Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to an improvement in the construction of the metallic
ends of warpers' and weavers' beams and the like.
The object of my invention is to obtain a flange that will combine strength
with lightness, and that will have a perfectly plain surface free from holes and
bolt heads on the face side, or that side which is next to the warp or material
that is on the beam, no bolts passing through or bolt holes being required in
said face side.
In the accompanying drawing
Fig. 1 represents a transverse section of a dished circular plate which I employ
for the face side of my improved flange:
Fig. 2 shows the same section of dished plate with a wood or metal ring
fitted on the centre rib or web of said plate:
Fig. 3 shows said wood or metal ring secured to the plate by the expanded
edge of the centre rib:
Figs. 4 and 5 are transverse sections of flattened dome shaped plates either
of which may be employed in combination with the aforesaid dished circular
plate to form the back of the flange.
Fig. 6 is a transverse section of a complete flange formed by a combination
of a plate as Fig. 3 and a plate as Fig. 4.
Fig. 7 is a plan showing the face of a complete flange and Fig. 8 is a plan of
the back of said flange.
Fig. 9 shows an edge view of the same flange with a boss attached thereto by
which to secure the aforesaid flange to a beam, but any preferred form of boss
may be employed.
In these views similar letters refer to similar parts.
In this invention I produce by stamping or pressing a sheet of mild steel or
iron, a dished sheet circular in form as shown in Figs. 1 and 7 the central rib
or web c being formed by the metal that is pressed upwards or inwards when
forming the hole : I place either a wood or a metal block as c or a block of
other suitable material on the aforesaid rib e and secure said block to the
plate a by expanding or bending over the edge el on to or over the inner edge
of the block as in Fig. 3, by which the aforesaid block and the plate a are
firmly united without any bolts or screws passing through the face of the plate;
I press a steel or iron plate or otherwise produce a flattened dome as f with a
hole in the centre: said plate may have ribs or webs thereon as g and Fig. 4,
or may be a plain dome shaped plate as Fig. 5, or may have a rib g around
the outer edge only as in Fig. 6. I place said dome shaped plate on to the
plate a as in Fig. 6 and unite the outer edges either by rivets 9 or other pre-
ferred means such as rolling the outer edge of the plate a over the edge of
the plate f: The centre portion of the plate f may be secured to the block c
by bolts or screws. In order to secure the flange to the beam a boss as m
or other preferred form of boss is bolted to the herein before described flange as
in Fig. 9 by the aforesaid bolts r which have been passed through the block c

page_text: and are employed to unite the plate f thereto: By these means a strong light
metallic flange is produced whose face is perfectly level and free from either
bolt holes or projections. In some cases I form hand holes as v in the aforesaid
dome shaped plate f. In a modification of my invention dispense with the
aforesaid dome shaped plate and employ only the dished plate a in combination
with the ring or metal block c which may have arms or ribs c¹ extending radially
therefrom as in Fig 10: an ordinary clip boss may be attached to the block c
for securing the flange to the beam.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1st. Flanges for warpers' and weavers' beams and like uses that are constructed
by the combination of a dished plate as a with a wood or metal ring c secured
to the central rib or web e of said plate by the inner edge of the web being
expanded within said ring or block and a dome shaped plate as f bolted or
otherwise secured thereto in the manner and for the purpose substantially as
herein before described.
2nd. In flanges for warpers' and weavers' beams and like uses that are con-
structed of two plates, one of said plates having a plain face, and the other
dome shaped, the means employed for enabling said two plates to be bolted
together, or a boss to be bolted thereto, without the bolts passing through the
face of the flange substantially as and for the purpose herein before described.
3rd. Flanges for warpers' and weavers' beams and like uses that are constructed
by the combination of a dished plate as a with a wood or metal ring or block
as c secured thereto by the central portion of said plate being pressed in, and
the inner edge of the web thereby formed being expanded within said ring or
block in the manner and for the purpose substantially as herein before described.
4th. Flanges for warpers' and weavers' beams and like uses that are constructed
in the manner substantially as herein before described.
