TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middle-
sex, Gentleman, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
REVERSIBLE FLOCK CUTTING MACHINES," and have petitioned Her Majesty to
grant unto me, my executors, administrators, and assigns, Her Royal

page_text: while the blades are confined between them, as seen in the Drawing.
7 are set screws, which pass through the lags and engage with the back
edge of the blades, so that each separate blade may be set up and
adjusted separately by the screws, as well as collectively, by means of
the hinged bed. The lags are supported on the bottom I of the bed,
and the blades are clamped between the lags by means of screws J,
which pass through the upper edge of the bed, and bear against a
metallic plate K, as seen in Figure 3. L is the cylinder composed of a
shaft m, supported in journal boxes on top of the frame A, as seen in
Figure 1, and spirally arranged blades n, which are fixed in an enlarged
portion of the shaft. O are adjustable plates between the blades, which
rest upon the springs P. These plates are adjusted with regard to the
edges of the blades by means of the set screws q. R is a cam groove on
the end of the longitudinal shaft S. The shaft is revolved by means of
the belt T from the cylinder shaft. U is a horizontal cam lever, with a
finger at one end which engages with the cam groove R, and an arm V
at the other end, which engages with a groove in the cylinder shaft, as
seen in Figures 1 and 2. W is the fulcrum of the lever U. By this
means a vibrating motion is given the cylinder. The cylinder shaft is
given a reciprocating motion, and slides in its boxes as it revolves, which
prevents grooves being worn in the blades. x is the cover or cap of the
cylinder, which is hinged by means of the arms y, y, to the top of the
frame or casing A. This cap is in the form of a hollow semi-cylinder,
with openings a, a, in its top. c, c, are shutters, which slide from each
end of the cylinder, confined by groove. picces d, d, (see Figure 3). Each
slide has an opening e, which receives the mouth of the hopper F, as seen

page_text: Fourthly. In combination with the bed B¹, the adjusting screw D,
and stop screw E, as and for the purposes shown and described.
Fifthly. The lags 9 and set screws h, in combination with the blades f,
as and for the purposes described.
Sixthly. The clamp screws J and plate K, in combination with the
lags g and blades f, as described.
Seventhly. The adjustable plates O and springs P, in combination with
blades n of a flock cutting cylinder, substantially as and for the purposes
described.
Eighthly. In combination with a flock cutting cylinder, the reversible
hopper F, and the cap x, when the same are constructed and arranged
substantially as and for the purposes described.

In witness whereof, I, the said John Henry Johnson, have to this
my Complete Specification set my hand and seal, this Fifth
day of September, One thousand eight hundred and seventy-
three.
