Year: 1878

page_text: LETTERS PATENT to William Heath, of Crabbs' Cross, near Redditch, in the
•
County of Worcester, Manufacturer, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR SMOOTHING AND POLISHING THE EYES OF NEEDLES, THE
THREAD HOLES OF SHUTTLES, AND OTHER PARTS OF SEWING MACHINES,
AND THE BARBS OF HOOKS USED THEREWITH, AND OF CROCHET HOOKS."
PROVISIONAL SPECIFICATION left by the said William Heath at the Office
of the Commissioners of Patents on the 19th March 1878.
WILLIAM HEATH, of Crabbs Cross, near Redditch, in the County of Worcester,
Manufacturer. "IMPROVEMENTS IN MACHINERY FOR SMOOTHING AND POLISHING
THE EYES OF NEEDLES, THE THREAD HOLES OF SHUTTLES, AND OTHER PARTS OF
SEWING MACHINES, AND THE BARBS OF HOOKS USED THEREWITH, AND OF CROCHET
Hooks."
This Invention refers to the smoothing or polishing the orifices or barbs in articles
of the above description, by means of a tensile line of wire or other suitable material
stretched between two adjustable standards upon a table similar to the slide bed of
a lathe. The standards support toothed-wheel driving gear and a shaft, upon one
end of which are fast and loose pulleys and driving band; the standards also
carry the clutches by which the tensile wire or line is held.
The needles, of any kind whatsoever, or other pierced articles, are threaded upon
this wire or line, or the hooks are hung upon it by the barb.
By the power applied from the driving band through the shaft and large wheels
to the pinions in gear therewith, upon the shafts of which pinions the wire or lino
is held securely and tightly stretched, a rapid revolving motion is imparted to the
wire or line within the eyes or orifices or barbs of the articles under operation, the
attendant by hand regulating the pressure upon any particular part of the eye or
barb.
