Nottingham, Hosiery Manufacturers, and ARTHUR HOPCROFT, Haywood Street,
Sneinton, Nottingham, Framesmith, do hereby declare the nature of this invention
to be as follows:-
Our improved apparatus consists of the following parts, from the fixed needle
bar of each jack and lead sinker straight bar knitting machine a requisite number
of brackets project to carry a bed plate, above which four flat bars slide longi-
tudinally. Each of the four bars carry a square bar near its back edge provided
with a series of thread guides at the distance apart required by the pattern to be
produced. Each square bar may be removed and another substituted with thread
guides nearer or further apart. The thread guides carried by the two bottom
square bars provide threads to form diagonal lines of plaited threads on the fabric
made. Each bar being provided with a ratchet toothed bar both engaging with a
toothed ratchet carried by a vertical axle revolving in a bearing secured to the
bed plate, below the bearing the axle carries a toothed ratchet wheel provided
with a spring and handle by which the two lower bars may be racked to or from
each other one or more needles at each course worked.
The bed plate and the four bars it carries are placed in position to lay their
threads on the needles by brackets secured to the sinker bar, the brackets operating
each time the sinkers are brought forward and sunk.
The two upper sliding bars are operated by cams and stop levers in the
usual way, but each bar is provided with a stud connected by a cord to a
rocking hand lever operated by the attendant to ensure the stop levers being held
to the cams.
Instead of sets of single thread guides, either or the whole of the square bars may be
provided with double ended rocking levers, the inner ends carrying two thread
guides the outer ends working on studs carried by a sliding bar provided with
a double ended stop spring. The sliding bar being operated by the attendant
when producing diamonds or other shapes of two colours each.

We GEORGE GOODALL of the Firm of I. and R. Morley Fletcher Gate,
Nottingham Hosiery Manufacturers and ARTHUR HOPCROFT Haywood Street
Sneinton Nottingham Framesmith do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 show in plan the left half and the right half of our improved
apparatus in the relative position the thread guides occupy beneath the needles of
a straight bar knitting machine previous to working a course.
Figures 3 and 4 show in plan the two halves of a set of bars provided with
levers each carrying two thread guides.
Figure 5 shows an enlarged vertical sectional view on the line A. B Figure 2 of
our improved apparatus in the relative position it occupies beneath the needles
of a straight bar knitting machine previous to working a course sufficient only of
the machine being shown to illustrate our invention.
Figures 6. 7. 8. 9 and 10 are enlarged views of parts of the apparatus each
severally referred to hereafter.
In each figure the corresponding parts are indicated by the same numbers where
necessary. Our improved apparatus consists of the following parts, from the fixed
needle bar of each jack and lead sinker straight bar knitting machine brackets .1
project to carry a bed plate 2, above which four flat bars 3. 4. 5. 6 slide, the bar 6
being under and in line with the bar 5, (see Figures 1. 2 and 5). Each of the
four bars carry a square bar near its back edge provided for each width of fabric
made on the machine, with a series of thread guides 34 (one of which is shown in
plan and a back end view at Figures 6) set the distance apart required by the
pattern to be produced. Each square bar may be removed and another substituted
with the thread guides nearer or further apart, according to the width of the
diamonds or other pattern to be made.
Near each end of the bed plate 2, an arm 7, projects carrying two rods 8, over
which the threads for the guides on the bars 5, and 6, are passed either from spools
or beams.
A stop pin 9 carried by each arm 7 slides upon the top of the bracket to prevent
the thread guides from falling beneath the needles lower than shown at Figure 5:
The two upper sliding bars are operated by cams 10 and 11 (shown by dotted
lines at Figure 2 and an enlarged view at Figure 7) and stop levers 10A 1B and
11 11 all in the usual way. But in addition each of the two bars 3 and 4 are
provided with studs 12 connected by cords passed round two pulleys carried by a
hand lever 13 rocking on a stud projecting from an arm 14 secured to the bed
plate 2, the lever being operated by the attendant ensures the stop levers, being
held to the cams 10 and 11, beneath the cams is a notched plate 15 held in position
by a spring 15 secured to the bed plate, the cams and plate revolve together on
a pin carried by a double ended bearing 16 secured to the bed plate. The plate
and cams being moved one notch in the direction of the arrow at the completion
of each course.
The four bars 3. 4. 5 and 6 slide independently and parallel to each other upon
studs 17 passed through slots in the bars and secured in the bed plate in the usual
way. A space is left between the back edges of the three lowest sliding bars and
the square bars to allow the threads to be passed to the guides. Outside each

page_text: bracket a bracket 18 is secured to the sinker bar as shown at Figure 5 the front
forked end engages with an axle pin 24 carried by the bel plate 2. The brackets
hold the bed plate and the parts it carries in the position shown moving the thread
guides outwards clear of the needles as the sinkers move to the front to knock the
work over the needle heads, then the brackets move the bed plate and parts inwards
placing the thread guides in the position shown at Figure 5 ready for the next
course. As the brackets rise with the sinker bar and clear the axle pin 2ª a
lever 1 operated by a spring 1 moves the bed plate and the parts it carries
outward to a stop plate C secured to the bracket 1.
The thread guides carried by the square bars sliding with the lower bars 5
and 6 provide threads to form diagonal or other shaped plaited threads on the face
of the fabric made. The bar 5 being provided with a ratchet toothed bar 19 and
the bar 6 with a ratchet toothed bar 20 both engaging with a toothed wheel 21
carried by an axle pin revolving in a bearing 22 secured to the underside of the
bed plate 2, (the whole shown in plan in an enlarged view at Figure 8,) below the
bearing the axle carries a notched plate 23 in which a spring 24 secured to the bed
plate engages and holds the ratchet toothed bars in position, the lower end of the
axle pin terminates in a handle 25 (shown only at Figure 5,) by which the two
lower bars 5 and 6 may be rocked to the right or left reversely to each other at
each course worked to traverse the threads over one or more needles.
The bed plate and the four bars and thread guides are placed in position to lay
their threads on the needles by brackets 18 secured to the sinker bar, the brackets
operating each time the sinkers are brought forward and sunk.
Instead of sets of single thread guides, either or both of the two upper square
bars may be provided with double ended levers 26 (shown in plan at Figures 2
and 3) rocking upon studs carried by a bar 27 attached by arms to either of the
sliding bars 3 and 4. The inner end of each lever carries two thread guides 34 the
outer ends of the levers engage with studs carried by a sliding bar 28 provided with
a double ended stop plate 29 held by a spring 30 secured to the sliding bar. The
several parts being shown enlarged in section at Figure 9 and one double ended
lever in plan at Figure 10. The sliding bar 28 being moved to the right by
the attendant the length between the stops of the plate 29 to throw the left guides
into the position shown by dotted lines out of work and the right guides into a
working position when producing diamonds or other shapes of two colours each,
according to the coloured threads supplied to the guides.
Before working a course the guides carried by the sliding bars 3 and 4 should
be over each other to form diamonds or other shapes of one colour if the single
guides are employed or of two colours if the double guides are employed, and the
guides carried by the bars 5 and 6 should be over each other and half way between
the guides above them as shown at Figures 1 and 2.
Each course is worked as follows: The bars 3. 4. 5 and 6 being in the position
shown at Figure 5 the bars 3 and 4 are held up to their stop cams 10, 11, by the
cords operated by the hand lever 13, the four sets of guides are then passed through
the needles and the bars 3 and 4 are traversed by the hand lever 13. The bottom
bars 5 and 6 are traversed by the handle 25 being moved to operate the bars 19. 20
attached to the guide bars 5 and 6 to lay their threads over one or more needles to
the right or left.
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 we
claim is :
1. The construction and employment in straight bar knitting machines of square
bars provided with thread guides 34 at the back of the bars 3. 4. 5 and 6, enabling
the threads to be kept seperate for each set of guides.
2. The construction and employment in straight bar knitting machines of
cords operated by a rocking lever is for holding the bars 3 and 4 up to their stop
cams.

page_text: 3. The construction and employment in straight bar knitting machines of two
bars 5 and 6 carrying thread guides 3^ for producing diagonal or other shaped lines
of plaited threads on the face of the fabric made.
4. The construction and employment of ratchet toothed bars 19. 20 attached to.
the bars 5 and 6 and traversed by a toothed wheel 21 on an axle carried by a
bearing 22 the axle being provided with a ratchet toothed wheel or notched
plate 23 held by a spring 24 and operated by a handle 25 for the purpose
specified.
5. The construction and employment in straight bar knitting machines for
making diamonds or other shapes on knitted fabrics of double ended levers 26 each
provided with two thread guides 3 and rocking on studs carried by a bar 27, the
outer ends of the levers engaging with studs on a bar 28 having a stop plate 29
held by a spring 30 for producing shapes of two colours substantially as described
for the purpose specified and illustrated in the drawings annexed.
