page_text: LETTERS PATENT to William Simpson Shepherd, of Armley Road, Leeds, in
the County of York, Woollen Rag Merchant, for the Invention of "IMPROVE-
MENTS IN MACHINERY FOR CUTTING OUT AND REMOVING SEAMS, LININGS, AND
OTHER SIMILAR THINGS FROM WOOLLEN AND OTHER RAGS."
Sealed the 26th February 1878, and dated the 8th September 1877.
PROVISIONAL SPECIFICATION left by the said William Simpson Shepherd
at the Office of the Commissioners of Patents on the 8th September 1877.
WILLIAM SIMPSON SHEPHERD, of Armley Road, Leeds, in the County of York,
Woollen Rag Merchant. "IMPROVEMENTS IN MACHINERY FOR CUTTING OUT AND
REMOVING SEAMS, LININGS, AND OTHER SIMILAR THINGS FROM WOOLLEN AND
OTHER RAGS.
The first part of this Invention consists in the use of a circular cutter or cutters
running on a shaft between a groove or grooves in two rollers which feed the rags.
These rollers are driven on separate shafts or spindles arranged in such positions
that the circular cutter or knife works within the grooves of the feed rollers with
the cutting edge at or about the point of contact of their rims, between which the
rags are passed.
When two cutters are used they are fixed parallel with each other on the same
shaft at such a distance apart as the width of seam to be cut out which passes
between the cutters.
The second part of this Invention is an ejector to throw out the cut off seams, and
consists in a loose ring on the shaft between the circular cutters, having a stem
(extending beyond the cutting edges) which throws out the seams.
The rims of the feed rollers are fluted (either their entire length or partially) and
fit or gear into each other to grip the rag more firmly.

page_text: The same form of ejector may be used to clear the grooves of the feed rollers of
any fragments, as described, for the double cutters. Springs or weights are used to
keep the feed rollers in close contact, and at the same time allow them to yield when
the thickness of the material passing through requires it. A small table is attached
in front of the feed rollers to guide the material on.
The supporting framing and driving parts may be of any convenient
construction.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Simpson Shepherd in the Great Seal Patent Office on the
7th March 1878.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents the front elevation of the machine, in which a, a, are the
driving pulleys, mounted on the cutter shaft b; b, cutter shaft; c, c, the cutters,
of which two are shown mounted, as before described; d, d, gearing for driving
feed rollers from cutter shaft b; e, feed roller shaft; ff.f.f, feed rollers, which are
roughened as described; g, spring on which the bottom feed rollers are mounted;

page_text: h, h, h, adjusting screws for setting up cutters to their proper position after
sharpening; i, small driving pulley on cutter shaft for sharpening cutters; j, j, j,
frame of machine bearings, &c.
Fig. 2 represents the side elevation of the machine, a, being the driving pulley;
b, the cutter shaft; c, c, the cutters; e, feed roller shaft; f, f, the feed rollers;
g, the spring on which the under roller is mounted; h, h, h, adjusting screws for
cutter; i, frame of machine; k, table on spring g, for feeding the materials from l,
the ejector for clearing cutter of the cut seams or waste material; m, ejector for
clearing grooves of feed rollers from waste seams; n, m, n, shows material passing
through the machine.
Fig. 3 represents end elevation of machine, with driving pulleys removed, and
shows gearing adjusting screws, and are referred to by letter as in Figs. 1 and 2.
Fig. 4 represents the plan of machine, in which the letters refer also to the parts,
as in Figs. 1, 2, and 3.
Figs. 5 and 6 represent the side and back elevations of feed rollers and cutters to a
large scale, and the letters refer, as before, in Figs. 1, 2, 3, and 4.
Having now fully described and illustrated the manner in which my Invention
is or may be carried into effect, what I claim as novel and desire to be secured to
me by the herein in part recited Letters Patent, is,―
First. The combined use of one or more circular cutters or knives running within
and between grooves in guide or feed rollers, substantially as described and illus-
trated, for the purpose named.
Second. The form of ejector shown to clear the cutters, the same being also
applicable to the feed rollers as described and illustrated.
In witness whereof, I, the said William Simpson Shepherd, have hereunto
set my hand and seal, this Fifth day of March, in the year of our Lord
One thousand eight hundred and seventy-eight.
