Improvements in Knitting Machines.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents, '
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention to be as follows:-.
This invention relates to knitting machines.
In knitting in knitting machines it is necessary prior to the formation of each
succeeding row of loops that the web already existing and suspended from the
needles shall be moved to the rear ends of the needles in order to provide sufficient
free space upon the hooks for the formation of the new row of stitches.
This moving back of the web suspended from the needles to the posterior ends of
the latter and the holding in this position is generally termed the "taking back" of
the web.
This taking back has heretofore been effected in different manners by the sinkers.
With stationary needles, the sinkers draw back the web and hold it fast and with a
movable needle bar, the sinkers descend during the knocking over and then, when the
needles advance again hold back the web. With vertical needles upon a movable
needle bar it is exactly the same; during the knocking over the sinkers advance,
and, when the needles ascend, hold back the web below. "Below" with verticaĺ
needles corresponds to "back" with horizontal needles. It is the same whether the
knocking over comb is fixed to the sinker guide, or arranged separately from it.
In all these and similar known arrangements the loop-sinking and dividing sinkers
are the means for taking back the loops.
They must for this purpose be moved specially the length of the needles, as the
width of the sinkers is considerable, and the path of the same long, so that operations
and movements occur which prevent the rapid motion of the loom."
According to the present invention I have arranged a separate taking-back comb
in the knitting frame, which comb relieves the sinkers of the work of taking back

page_text: the loops. The said comb can be applied to a cotton frame, or to any other knitting
frame and is constructed as follows."
Each knocking over tooth has a taking back tooth and these teeth form a comb
during the formation of the loops.
The knocking over comb can be arranged separately from the presser and sinker
guide. In this case it contains in like manner as above, the taking back comb, whose
taking back teeth are made integral with the knocking over teeth and act exactly as
above.
Between the sinkers and the knocking-over comb can be inserted a special taking-
back comb fixed for example to the sinker guide. It acts thero in the same manner
as above specified.

I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 :-
This invention relates to knitting machines.
In knitting with knitting machines it is necessary prior to the formation of each
succeeding row of loops that the web already existing and suspended from the needles
shall be moved to the rear ends of the needles in order to provide sufficient free space
upon the hooks for the formation of the new row of stitches.
The said invention is illustrated in the accompanying drawing the Figures of which
are hereinafter referred to.
The moving back of the web w¹ (Figure 1) suspended from the needles to the
posterior ends of the latter into the position w and the holding in this position by the
sinker nibs p is generally termed the 'taking back' of the web.
This taking back has heretofore been effected in different manners by the sinkers
as shown for example in the hand-frame, Figure 1, in the Paget frame, Figures 2
and 3, and in the cotton frame Figures 4, 5 and 6. With stationary needles,
Figure 1, the sinkers p draw back the web w and hold it fast and with a movable
needle bar, Figures 2 and 3, the sinkers p descend during the knocking over,
Figure 2 and then, when the needles a advance again, Figure 3, hold back the web.
With vertical needles upon a movable needle bar, (in the cotton frame Figures 4, 5
and 6) it is exactly the same; during the knocking over, Figure 4, the sinkers p
advance, and, when the needles ascend, Figures 5 and 6 hold back the web below.
("Below" with vertical needles corresponds, to "back" with horizontal needles).
It is the same whether the knocking over comb c is fixed to the sinker guide, Figures 4
and 5 or arranged separately from it, Figure 6.
In all these and similar known arrangements the loop sinking and dividing sinkers p
are the means for taking back the loops. They must for this purpose be moved
specially, the length of the needles, as the width of the sinkers is considerable, and
the path of the same long, so that operations and movements occur which prevent the
rapid motion of the loom.
According to the present invention I have arranged a separate taking-back comb in
the knitting frame, which comb relieves the sinkers of the work of taking back the
loops. The said comb is shown in Figures 7 to 16 as applied to a cotton frame, it is
adapted in like manner as will easily be seen to any other knitting frame and is
constructed as follows.
Each knocking over tooth c, Figures 7 to 16 has a taking back tooth e and the
whole row of these teeth form a comb e during the formation of the loops used in the
following manner. In Figure 7 the web w is held by a taking back tooth below
upon the needles and the new loops f are sunk by the sinkers p which now no longer

page_text: contain the projecting teeth (Figure 6). The needles a then descend and shift
against the presser edge 6 which closes its hooks, whereupon the sinkers p move
back, Figure 8. After the pressed hooks have passed further down and through the
old loops w, the needles a move away from the presser to the front of e Figure 9,
and descend further for the knocking over, Figure 10; then they move behind to
below the taking back tooth e, Figure 11, and ascend Figure 12, e holding back the
web w, and now the sinking of the loops commences again. Also when the narrowing
takes place the taking back combe is operative to hold back the web w when the
loops are covered. Figure 14 shows part of the cotton frame having the new taking-
back comb e as above described.
When the knocking over comb is not against b, d but arranged separately from
the presser and sinker guide as in Figure 15, it contains in like manner as above, the
taking-back comb, whose taking-back teeth e are made integral with the knocking
over teeth and act exactly as above.
Between the sinkers p and the knocking over comb c can be inserted a special
taking back comb e¹ as shown in Figure 16 fixed for example to the sinker guide b d.
It acts there in the same manner as above described.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed as communicated to me by my
foreign correspondent I wish it understood that I claim.
For flat knitting frames a taking back comb e which, independently of the loop-
sinking and dividing sinkers p, effects the taking back of the web, either as part of
the knocking-over comb c, or as a separate comb e', placed between the sinkers p and
knocking-over teeth c.
