We AMBROSE BREWIN, of the firm of Revis, Brewin and Marriott, Goldsmith Street
Works, Nottingham, Machinists, ROBERT EDGAR PARR and NOAH KIRK, Cranbourne
Street, Leicester, Hosiery Manufacturers, do hereby declare the nature of this
Invention to be as follows:-
The object of our invention is to prevent tho fabric run on the needles from
loading them and thus avoid the breaking off of the beards of the needles, this is
effected by the following incans.
Instead of moving two levers separately by hand to traverse the trucks on the knocking
over bar cams, in a straight bar knitting machine, we connect the upper ends of two
forked levers to a bar for that purpose, said bar is also connected to the upper ends
of three other forked levers, which traverse the trucks operated by the pressing cams,
on to additional cams secured to the sides of the pressing cams. The axles of the
trucks are made longer than heretofore to allow of such extra traverse.
By such means when the heels of hose or half hose, or the bulk of other fabrics
are run on the frame needles, the traverse of the trucks on to the additional cams
ensures the needles being pressed clear without being loaded by the fabric run
on the needles, such loading causing the needles to misspress or the beards to be
broken off.

DESCRIPTION OF THE DRAWINGS.
Figure 1, is a sectional view looking from the right end of a straight bar knitting
machine with our improved apparatus applied thereto.
Figures 2 and 3 show front views of two levers severally referred to hereafter.
In the three figures portions of a straight bar knitting machine only, are shown,
sufficient to illustrate our invention, the corresponding parts in each figure are
lettered alike.
The object of our invention is to prevent the fabric run on the needles from londing
them and thus avoid the breaking of the beards of the needles.
This is effected by the following means.
In the sectional view figure 1, the needles A jacks A', jack sinkers A³, and knocking
over bits A, are shown in the relative positions they occupy when the needles are at
their highest position, after the thread carrier has laid its thread. upon them and the
sinkers have formed the loops.

Instead of moving two levers separately by hand to traverse the trucks on the
knocking over bar cams we connect the upper ends of two forked levers B"
which is shown in front view at Figure 3° to a bar B'. The lever B rocks on an

page_text: •
axlo B secured in a short arm projecting from the right side of a levor B³ which is
carried by the usual rocking shaft B3 which is provided with arms supporting the
knocking over bar.
The forked end of the lever B traverses a truck B³ on to an additional knocking
over cam 3 secured to the right side of the ordinary knocking over cam 2.
The cam 1 to the left being the knocking over cam used when the cam shaft is
traversed, while the fabric is being fushioned.
"
The bar B is also connected to the upper ends of three other forked levers C“ one
of which is shown in front view at Figure 2." The lever C rocks on an axle C
projecting from the right side of a lever C which is carried by the front rocking
shaft C and connected by a hand lever C to the lower end of the needle bar arm
for operating the needle bar.
The lower end of the lever is held by a spring to a stop pin projecting from
an arm C adjustable on a lower front shaft in the usual way.
The forked end of the lever C traverses a truck C on to an additional pressing
cam 6 secured to the right side of the ordinary pressing cam 5 the cam 4 being the
pressing cam used when the cam shaft is traversed while the fabric is being
fashioned.
When the heels of hose or half hose, or the bulk of other fabrics are run on the
needles the trucks B and C are traversed on to the additional cams 3 and 6
respectively by the attendant raising a catch lever D and moving a hand lever D' to
the right as shown at Figures 1 and 2.
The hand lever D' rocks ou an axle projecting from a bracket D² secured to the
framing of the machine, the front of the bracket forming a stock D³ up to which the
hand lever D' is moved. The back end of the lever is slotted and engages with a
stud D secured to the bar B¹.
To prevent the damage which would occur in case the attendant omitted to reverse
the hand lever after the bulk of fabric has cleared the needles, the two additional
knocking over cams 3 are each provided with an incline piece 34 which forces the
trucks B and C to the left on to the ordinary knocking over cams 2 and 5.
The rocking of the levers traverses the bar B and stud D to the right causing the
• handle D' to engage with and be retained by the catch lever D while the ordinary
cams are at work.
By the employment of our improved apparatus to straight bar knitting machines,
when the trucks are traversed on to the additional cams, the needles are held
closer to the presser bar E to firmly press the beards into the eyes of the needles,
and thus ensure that the ribbed top or other bulk of fabric is passed clear over
the beards of the needles, thus avoiding the frequent breakages of needles heretofore
experienced.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what wo
claim is :
The construction and employment of improved apparatus operating in conjunction
with a straight bar knitting machine for the purpose specified substantially as
described and illustrated in the Drawings annexed.
