PROVISIONAL SPECIFICATION.
"Improved Means of Attaching Metal Flanges upon Beams or
Rollers.
I JAMES WILCOCK of No. 2 Charles Street, Littleborough in the County of
Lancaster, Pattern Maker, do hereby declare the nature of this invention to
be as follows:-
―
,
The object of this invention is to dispense with the use of wooden wedges or
set screws for fixing or attaching flanges upon loom beams, warp beams and similar
rollers, and to provide simple and quickly adjusted devices for such purpose.
According to my invention I cast the flange without a boss but with a series of
two three or more straight ridges projecting from one face and arranged around
the central hole or opening through which the beam is to pass, at suitable and
equal distances apart, and preferably tangential to a circle concentric with the said
central opening at a point in the centre of their length.
Around the central opening of the flange I arrange two three or more segments
forming together a boss surrounding the beam or roller.
Each segment of the boss is provided with a flange-like projection fitting against
the flange to be fixed on the beam and of convenient depth, diminished in thickness
at its outer edge so as to form with one of the projecting ridges on the flange a
tapered recess into which I can drive a tapered flat cotter which will press the
segment of the boss tightly against the beam or roller and so secure the flange
firmly thereto.
The cotter is kept in place by a nut and a bolt passing through a hole in the
flange, a radial slot in the corresponding part of the segment, and a longitudinal
slot in the cotter, or by other equivalent means, say by undercutting the projection
on the flange and the segment.
If desired the central part of each of the projecting ridges on the face of the
flange may be recessed or cut away and the corresponding part of the segment
made rather longer to allow for the bolt for holding the cotter in place.
In some cases other devices may be employed instead of the cotter for pressing
the segment against the beam or roller, the projections on the face of the flange
being suitably modified.
For example a revolving cam or eccentric might be mounted upon the segment
bearing against a projection on the flange, the bolt or centre upon which the cam
or eccentric is mounted passing through a slot in the flange; or the segment could
be slotted and the cam mounted upon the flange, in which case the projections upon
the latter could be dispensed with, but I prefer to use these projections.
I provide suitable guides upon the flange between which the flanged parts of the
segments can slide.
By my improvements the flanges can be very quickly attached or readjusted
upon their beam or roller.

I JAMES WILCOCK, of No. 2 Charles Street, Littleborough in the County of
Lancaster, Patern Maker, 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 :—
The object of this invention is to dispense with the use of wooden wedges or set
screws for fixing or attaching flanges upon loom beams, warp beams and similar
rollers, and to provide simple and quickly adjusted devices for such purpose.
The invention will be readily understood from the following description on
reference to the accompanying sheet of drawings of which
Fig. 1 is a side elevation of a warp beam and flange attached according to my
invention shewing and having one of the adjusting wedges removed and shewn
detached in elevation and section-at-Fig. 14.
Fig. 2 is a sectional edge view of Fig. 1 and Fig. 3 illustrates a modification
hereafter more particularly referred to.
According to my invention I cast the flange a without a boss but with a series
of two three or more straight ridges a projecting from one face and arranged
around the central hole or opening-through which the beam b is to pass (see Fig. 1)
át suitable and equal distances apart, and preferably tangential to a circle concentric
with the said central opening.say, at a point in the centre of their length.
Around the central opening of the flange Itarrange two three or more segments c
forming together the equivalent of a boss surrounding the beam or roller b.
Each segment c of the boss is provided with a flange-like projection c¹ see also
detached view Fig. 24 fitting against the flange a see Fig. 2 to be fixed on the
beam band of convenient depth diminished in thickness at its outer edge see Figs. 1
and 24 so as to form with one of the projecting ridges a' on the flange a tapered
recess into which I can drive a tapered flat cotter d shewn detached at Fig. 1ª
which will press the segment of the boss tightly against the beam or roller and so
secure the flange firmly thereto.
The cotter d is kept in place by a nut e and a bolt e¹ passing through a hole in
the flange a radial slot in the corresponding part of the segment c and a
longitudinal slot d' in the cotter, or by other equivalent means, say by undercutting
the projection a' on the flange a and that on the part cl of the segment c.
If desired the central part of each of the projecting ridges a¹ on the face of the
flange a may be recessed or cut away as seen at Fig. 1 and the corresponding
part of the segment made rather longer to allow for the bolt e¹ for holding the
cotter d in place.
In some cases other devices may be employed instead of the cotter d for pressing
the segment c against the beam or roller b the projections on the face of the flange a
being suitably modified.
For example a revolving cam or eccentric might be mounted upon the segment
bearing against a projection on the flange, the bolt or centre upon which the cam
or eccentric is mounted passing through a slot in the flange; or the segment c
could be slotted and the cam c+ mounted upon the flange a, in which case the
projectious upon the latter could be dispensed with, but I prefer to use these
projections.
I provide suitable guides at upon the flange a between which the flanged part c¹
of the segments can slide.
By my improvements the flanges can be very quickly attached or readjusted
upon their beam or roller.

tion and in what manner the same is to be performed I declare that what I
claim is :-
The improved means hereinbefore set forth for attaching metal flanges upon
beams or rollers.
