IMPROVEMENTS IN CIRCULAR KNITTING MACHINES FOR THE PURPOSE OF PRODUCING STRIPES IN THE ARTICLES MADE THEREIN
Year: 1877

page_text: LETTERS PATENT to William Eaton Cheetham, of Addison Villas, in the Town
and County of the Town of Nottingham, for the Invention of "IMPROVEMENTS
IN CIRCULAR KNITTING MACHINES FOR THE PURPOSE OF PRODUCING STRIPES
IN THE ARTICLES MADE THEREIN."
Sealed the 29th December 1877, and dated the 2nd July 1877.
PROVISIONAL SPECIFICATION left by the said William Eaton Cheetham at
the Office of the Commissioners of Patents on the 2nd July 1877.
WILLIAM EATON CHEETHAM, of Addison Villas, in the Town and County of the
Town of Nottingham. "IMPROVEMENTS IN CIRCULAR KNITTING MACHINES FOR
THE PURPOSE OF PRODUCING STRIPES IN THE ARTICLES MADE THEREIN."
My Invention consists in having fixed to the ordinary circular knitting machines
an improved self-acting striper, which consists of a circular ratchet wheel and levers
attached, worked by means of a catch connected to the shaft of the frame (or under-
neath the head); this ratchet wheel is connected to a circular shaped plate by an
adjustable connection, and the two form the pattern wheel, which according to its
regulation make the various patterns or stripes required.
The way in which this pattern wheel regulates the motion of the carriers is by
having upon its surface a series of adjustable horizontal slides or studs; these
horizontal slides or studs act upon levers that are in direct connection with the
various thread carriers, the number of which may be increased at pleasure. Springs
are placed in order to insure the regular working of the levers to the horizontal
cams, slides, or studs placed upon the pattern wheel. The thread carriers, which are
placed on a fulcrum, are caused to rise and fall by the levers pressing upwards and
downwards in the form of a connecting rod connection. When the carriers are not
in work the thread is held by a spring.

page_text: By means of rods taken from the first pattern wheel on one head to others
heads the thread carriers are worked in like manner as above described.
I can also work my Invention by means of a vertical pattern wheel, but I prefer
the method above described.
The Invention is applicable to both latch and bearded needles.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said William Eaton Cheetham in the Great Seal Patent Office on the
2nd January 1878.
WILLIAM EATON CHEETHAM, of Addison Villas, in the Town and County of the
Town of Nottingham. "IMPROVEMENTS IN CIRCULAR KNITTING MACHINES FOR
THE PURPOSE OF PRODUCING STRIPES IN THE ARTICLES MADE THEREIN."
My Invention consists in having fixed to the ordinary circular knitting machine
an improved self-acting striper; which consists of two modifications.
In my first modification I have a circular ratchet wheel and levers attached, worked
by reason of a catch connected to the shaft of the frame (or underneath the head);
this ratchet wheel is connected to a circular shaped plate by an adjustable connec-
tion, and the two form the pattern wheel which, according to its regulation, makes
the various patterns or stripes required.
The pattern wheel regulates the motion of the various parts by having upon its
surface a series of adjustable horizontal slides or studs; these horizontal slides or
studs act upon levers that are in direct connection with various thread carriers, the
number of which may be increased at pleasure. Springs are connected to the levers.
to regulate their working. The thread carriers are caused to rise or fall by the
levers pressing them upwards or downwards.
By the means of rods taken from the first pattern on one head to other heads
the thread carriers are worked in like manner as described.
My second modification consists of employing a chain having at suitable distances
projections attached, working, round a drum or wheel; these projections act upon
the guides or levers in the same or similar method to the projections on the catch
wheel described above.
The form of loop wheel that I prefer is an ordinary one with a groove above.
the nib.
Having now described the nature of my said Invention, I shall now more par-
ticularly describe the same, having reference to the annexed Sheets of Drawings.
In Figure 1 the front elevation of an ordinary circular head is shown having my
improved striper attached; Figure 2 is a plan.

Figure 3 is the pattern wheel used in my second modification; Figure 4 'shows
detail of same.
a, a, in Figures 1, 2, 3, 5, are the guides; b, b, Figures 1, 2, 3, is the drum or
wheel upon which the chainz, having the projections o, works; c, in Figure 2; is the
"sley" or guide for a; d, in Figures 1, 2, is the "head;" e, in Figure 2, is the
guard or "push-back;" f, in Figure 1, is the cam; j, in Figures 1, 2, 3, is the bracket
for carrying pattern wheel and chain (or striping wheel); i, Figures 1, 2, is the
bracket for spring and fulcrum; p, in Figures 1, 2, 3, is ratchet wheel or drum on
striping wheel; r, Figures 1, 2, is the lever for racking; s, Figures 1,,2, is the

page_text: bracket for same; t, in Figures 1, 2, is the truck working upon cam f; x, in Figure 2,
is the position of scissors to cut the thread; 1, 1, in Figures 1, 2, is ordinary
main shaft; m, m, in Figure 2, the frame; A, Sheet 3, shows the form of blade to
my improved loop wheel.
Figure 7 shows pattern wheel of my first modification.
Having now fully described and ascertained the nature of the said Invention,
and the manner of performing the same, I wish it understood that I claim, the
arrangement of striping apparatus, substantially as described, and the form of blade
of loop wheel.
In witness whereof, I, the said William Eaton Cheetham, have to this my
Specification set my hand and seal, this Nineteenth day of December, in
the year of our Lord One thousand eight hundred and seventy-seven.
Witness to the signature of the said
William Eaton Cheetham,
