adjustable for the purpose of regulating the length of mesh.
The pushing down of the freely moveable needle sinkers d d and e e¹ is effected
in the following manner :-
Supposing Figure 3 to be a needle foot which meets the needle sinker by the
motion of the lock a horizontal pressure in the direction of the arrow k will be
exercised. The sinker cannot move in this direction and the pressure is resolved
into the two components n and m. The pressure m is met by the screws pi while
the pressure in the direction n moves the sinker downwards.
Wire is usually manipulated in a hard state and it therefore unrolls itself from
the bobbin unless the latter is provided with a brake, and even in that case the
meshes are not of uniform length unless the wire is fed to the meshes.
Another part of our said invention relates to the feed mechanism for the wire
which we will describe with special reference to Figures 5 6 and 7. Figure 6 is a
plan partly in section looking in the direction of the arrow B³. B' and B² are
conical feed rolls pressed towards each other by springs C1 C2. Before the
rollers is a guide D adjustable in the direction of the axes of the conical rolls
by means of a screw D' working in a nut in the guide. If the wire is passed
between the smaller ends of the conical rolls the length of wire they draw is less
than if passed between the larger ends. The bobbin of wire E is provided with
any kind of brake. F is a weighted lever which keeps the wire stretched and
takes up slack when the slide a is reversed. The entire feed mechanism moves
with the slide a. The rotation of the conical feed rolls is derived from a stationary
rack M extending the length of the needle bed A. Into the rack gear the
pinions GG (see Figure 7 which is a plan view seen from underneath in the
direction of the arrow G³ of Figure 5). The pinions G' and G2 are secured to
the larger toothed wheels H H which turn alternately to the right and left
according to the direction of motion of the slide a. To always turn the
rolls B B so as to take the wire from the bobbin the wheels G' H and G' H'
are mounted on a carrier J. When the slide a and with it the feed mechanism
about reaches the end of its course the carrier J strikes a block J which displaces
the carrier in such a way that the wheel H2 comes into gear with the wheel K
whereby the wheels K' K2 revolve in the same direction as before notwithstanding
that the slide a travels in a direction opposed to that of the arrow v.
The knitted wire fabric (Figure 4) is produced by the needles of two opposite
needle beds A' A². The mesh bars t and u therefore alternate and the so called
right and left knitting which is noted for its elasticity is produced.
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. In a machine for knitting fabrics of metal wire a lock having moveably
arranged needle sinkers hollowed in such a way as that only one needle is in the
lowest position while the other needles are free substantially as hereinbefore set
forth and described with reference to the accompanying drawings.
2. In a machine for knitting fabrics of metal wire a feed mechanism for the wire
consisting of conical rollers travelling with the slide and deriving motion from a
fixed rack through toothed wheels alternately coming into gear substantially as
and for the purpose set forth and shown.
3. As a new article of manufacture a knitted right and left fabric of metal
wire substantially as herein described and shown in Fig. 4.
