PROVISIONAL SPECIFICATION.
Improvements in Yarn Beams Made of Wood.
JAMES SCHOFIELD of Stubley Hall, Littleborough, in the County of
Lancaster, Fustian Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My said invention relates to the wooden beams ordinarily used to contain yarn,
such as warp. and loom beams and beams used in the processes of sizing and
dressing yarns as is well understood." The invention relates more particularly to an
improved mode of applying and securing the end flanges of such wooden beams.. Ät
[present the usual method is to slip the flanges upon the ends of the turned beam
and wedge them in position, the central gudgeons having been previously driven
into the ends of the beam,. a binding or cutting ring being first pressed into the
beam euds so as to prevent splitting. The wedges which secure the flanges to the
beam are very apt to become loose and drop out. especially when the beam is
subjected to changes of temperature or exposure to weather.
According to my invention I cast or form the flange with a collar or ring the
internal diameter of which is equal to the diameter of the turned. beam. The
internal circumference of the said ring is or may be furnished with one or more
vee shaped tapering ridges which taper from nothing on the inner side of the
flange to the full depth of the ridge on the outside.
The flanges are forced upon the turned ends of the beam, the vee shaped tapered
ridges cutting their own beds into the wood, so that when iu position they constitute
keys, locking the flanges more firmly upon the beam and preventing turning when
in situ. The flanges with their encircling and binding collars or rings having been
thus forced on the beam ends I then drive the tapering shanks of the gudgeons
into the holes, bored to receive them in the ends of the beam.
The bursting or splitting of the beam ends which has heretofore been
counteracted By the binding or cutting rings already mentioned is, under my
invention obviated by the encircling collars or rings on the flanges, so that I am
enabled to dispense altogether with the use of such binding or cutting rings. The
expanding effect of the driven in tapering shank of the gudgeon is such as to give
the greatest expansion or tension of the roller end at the extreme end and this has
the effect of holding the flange more securely on the roller end and preventing it
from coming off.
When the gudgeons have been thus driven into the beam, the journals may be
turned thereon and the beam is ready for use. I prefer to form the flange in one
with the encircling-collar and ring, but if thought fit the flange might be made
detachable. My improved mode of applying and fixing the end flanges of yarn
beams makes a more secure and permanent job and can be carried into effect at less
cost than is the case under present practice.
Dated this 15th day of February 1895.

page_text: Having now particularly described and ascertained the nature of my said inven--
tion and in what manner the same is to be performed I declare that what I
claim is.
1. The improved mode of securing the end flanges upon yarn beams made of
wood, substantially as described and illustrated.
2. As means for securing the end flanges upon yarn beams made of wood and for
the preventing the splitting of the beam ends, forming the said end flanges with
collars or rings fitting the ends of the beam and having tapering vee shaped ridges,
which sink into the wood as the flanges are forced upon the beam, substantially as
described and shown.
3. As means for the indicated and expressed purposes the combination of the
flanges b with rings formed with tapering vee shaped ridges or keys, the wooden.
beam. a, and the gudgeons c driven into the beam ends substantially as described.
and illustrated
