page_text: We, ERNST JULIUS SEYFERT and HEINRICH HERMANN DONNER Manufacturers,
of Chemnitz, in the kingdom of Saxony, 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:-
Raised (covered or double mesh) patterns in woven fabric are formed by single
meshes a (Fig. 5.) of the wires being removed from their place and hung upon the
contiguous needle c, therefore brought together with the contiguous mesh c (a 1.).
When such patterns are produced on Lamb's knitting machine, only one needle
row, for instance the rear one, makes the smooth fabric, and the front row has been
changed into a pattern machine in the following manner.
The front needle bed A contains needles & without hooks, with an angle piece
bent up, as shown by Fig. 1, at the upper extremity, or, in lieu of these needles
also, wires may be employed, which are filed out at the upper end in the shape of
the angle a d.
The pattern needles d, situated opposite to the interstices between cc (Figs. 2-4.
and 6) are equal in number to the mesh-needles c; those pattern needles, which are
not in action, and not intended to cover the opposite meshes of the wires, are
pulled down into the bed A, like ordinary mesh-needles, whereby their lower
working hooks are brought entirely under the lock ikk (Fig. 6), while the active
needles & are set in motion by this lock in a suitable manner. When a row is
formed, both needle rows d and c are lifted (Fig. 1, c in dotted position) and the
thread guide lays the thread on both needles..
The mesh needles c are moved in the usual manner by an ordinary lock e f g
(Fig. 6); they draw their loops as meshes down through the preceding or old
meshes; the pattern or covering needles d (or wires) however are kept in elevated
position until the next row is reached, each of them holding a wire mesh a (Figs. 1
and 2). At the close of the first and before beginning the next row of meshes, the
needle bed A is shifted sideways for the distance of one or more needles, either in
the usual manner by hand or automatically, (for instance for the distance of one
needle) in the direction x (Fig. 2); thereby each pattern-needle d, which is in
action, draws its loop a sidewise away towards a¹ (Figs. 3 and 4) and holds the
same open before the contiguous needle c, now situated opposite to it. At the.

page_text: beginning of the next row, however, the mesh needles c are first raised, (in
the direction, Figs. 3 and 6) and penetrate into the loops a¹. Subsequently,
the pattern needles d are lowered, and thereby drawn out of the loops a¹ and
leave the latter hanging on the mesh needles c, consequently they have hung the
wire meshes a on the machine or mesh-needles in the shape a¹. In the case, that
a divided needle-bed is employed, (see German Patent No 611) the hanging up
covering or doubling can be effected by some needles to the right, and by others
to the left, as is often required.
The lock for the pattern or lifting needles is arranged as indicated by Fig. 6.
(In Fig. 6 all pattern-needles d are shown as being in action:)
After the pattern needles d, previous to the commencement of a row, have been
shifted sideways with the wire meshes of the preceding row, the slide with both
locks may be supposed to move in the direction y.
In that case k¹ meets the pattern needles d, which are still elevated and r lifts
the same a little higher, thereby putting an upward strain on the wire loops, or
meshes, held by the same, (a Fig. 1). While d hold these loops, as shown by
Figs. 3 and 4, f(Fig. 6) drives the mesh-needles c upward (1-2), and into the said
loops. Subsequently lowers the pattern needles d, which therefore are drawn
out of these loops and have transmitted the latter upon c. At last again lifts
the pattern needles, while c remain lifted (as shown by dotted lines by Fig. 1
d and c) and the tbread guide lays the fresh thread on both, which is pulled down
by c to form meshes c being lowered by g, while the pattern needles & remain
elevated (but slightly lowered by h¹ for facilitating the sliding off on the other side)
and keep their loops or meshes until the formation of the next row.
A further improvement of Lamb's knitting machine relates to the manner of
securing the needle bed and to its capacity of being displaced. The improvement
consists in so arranging in the machine frame b one of the two needle beds A or B,
one of which has hitherto always been arranged to be shifted sidewise (perpen-
dicularly to the direction of the needles) and the other bed to be lowered (parallel
to the direction of the needles), that the latter may be shifted laterally (per-
pendicularly to the direction of the needle) as well as lowered parallel to the
direction of the needle, so that both movements may be effected by one of the
needle beds, while the other needle bed is either only adapted to be lowered, or is
stationary.
This improvement is represented by the annexed drawings, Figs. 7 and 8 being
side views in two different positions and. Fig. 9 a front view. A longitudinal
groove is worked into the side cheeks b of the machine frame, in which groove the
rail c may be shifted.
On this rail c the needle carrier A is fastened by means of screws'd, so as to allow
it to be shifted downward, in the direction of the needle, owing to a slit hole 8, (see
the direction of the arrow), but not upward.
To secure it in its upper position the needle plate A, while working, a second
longitudinal rail e is fitted into the side cheeks bb, under the needle bed A, which
rail carries two oblique nozzles f, by means of which the needle-carrier A. is pressed
upward and retained in this position.
For lowering the needle plate A, the rail e is shifted to the right by means of
the handle p (direction of the arrow) the nozzles ff get into the recesses g g of the
needle-bed A, which, owing to its weight, falls down and moves downward in
the direction of the axis of the needles. The lateral shifting of the bed A is
effected by a curved lever i, which catches between two pins kk, mounted on the
rail c and shifts during the motion of the lever i the rail c and with it the needle
bed A sideways. The rail c is fitted with slots and secured (in a manner, which
allows the rail to be shifted) to the side cheeks bb by means of screws h.
The other or rear needle-bed B is, as usually, fastened directly on the cheeks bb
or may be arranged for being lowered in the direction of the needles by means of
slots and a similar rail e with nozzles ƒ ƒ.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
In Lamb's knitting machine:
1.) A doubling or covering apparatus, comprising an entire or divided adjustable
needle bed, provided with covering instruments (needles without hook wires or
similar appliances) and with a lock adapted to set in motion the covering instru-
ments in such a manner, that, while knitting one row, they hang or double the
wire meshes of the previous row upon the needles, and also seize the meshes of
the new row and hold them, until the next row is reached.
2.) Needle beds, secured in such a manner, that one of them may be moved in
the longitudinal axis of the machine and also in the direction of the needle axis.
The whole substantially as described.
