PROVISIONAL SPECIFICATION left by Florent Joseph Pieton at the
Office of the Commissioners of Patents, with his Petition, on the
12th May 1855.
I, FLORENT JOSEPH PIETON, Manufacturer, of Wignehies, Town in the
French Empire, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN KNITTING MACHINERY" to be as follows:-
My Invention consists in the adaptation of certain machinery to large and
small circular knitting frames or looms, whereby two threads may be fed to
the needles at the same time.
I am aware that certain arrangements have been proposed whereby circular
frames could work a single thread, but these when applied to small frames
caused frequent breaking of the needles. Now, the machinery I employ can
be readily adapted to small frames without straining the needles, without
causing any defects in the work produced, while it ensures more work and of a
superior quality being produced in a given time than by any other arrangement
of circular knitting frames.
Figure 1 of the Drawings annexed is an elevation of a small circular knitting
frame, with my machinery applied thereto; Figures 8, 4, 5, and 6 shew the
parts detached.

page_text: Each carrier a of the double thread apparatus is connected to the stationary
plate b, and for each thread precisely similar apparatus is employed. It consists
of an arbor c, one end of which turns in a fixed bearing, the other end in a
regulating screw d. The frame e, which carries the arbor c, may be fixed at
any required height by means of the rod 7, which is free to slide in a socket a',
in which it is fixed by a thumb screw f. The arbor c carries two wheels g, h;
the smaller g gears into the foot of the needles, and guides the other wheel h.
The guide wheel 9 governs and maintains the action of the wheel h upon the
barbs of the needles. The wheel h is represented in two detached views,
Figures 5 and 6. The face of the wheel is composed of hollow parts and of
flush parts set at an angle or inclined. The flush parts press upon the barb
of the needles, and the thread passes over it; on the other hand the hollow parts
do not exert any pressure whatever, and the thrend passes under the barb.
After the two arbors c follows a doffer or pushing-off wheel m; it is held in the
carrier a by the rod l'. This wheel is constructed to receive hooked needles,
and in such manner that should a tooth break by loosening a screw which holds
the two side plates of the wheel together, another needle may be inserted
between them; the screw must then be tightened, and all the needles become
fixed in grooves between the two side plates. Figure 2 shews the position of
the two apparatuses c, and of the doffer.
By varying the divisions on the wheels h, h, the pattern of the fabric may be
altered to suit any desired combinations. Figure 7 shews the formation of the
laying of the two threads with the two wheels h, supposing one to be one needle
behind the other, and supposing each wheel to consist alternately of one plain
tooth r, and of three hollow divisions, the number of which may be varied,
I propose that two sets of my apparatuses should be applied to each frame.
