IMPROVEMENTS IN KNITTING MACHINES
Year: 1884

page_text: I LUKE WOODWARD of Lee Works, Arkwright Street, Nottingham Hosiery
Machine Manufacturer do hereby declare the nature of my invention for
" IMPROVEMENTS IN KNITTING MACHINES to be as follows:-
ور
The object of this invention is to give greater rigidity to the jack levers of
knitting machines to prevent their yielding sidewise when acted upon by the
incline or slur cock.
For this purpose I form each of the blades of the comb between which the jack
levers work with two projections to come on opposite sides of the line of travel of
the incline or slur cock; just sufficient space being left between the projections to
allow the incline or alur cock to pass freely. In this way each jack lever will be
supported at two points close up to that part of it which is acted upon by the slur
cock or incline as well as being supported at its tail end where it turns upon
a fixed pin carried by the comb. One of the projections above mentioned is at the
front end of each blade of the comb and this projection I extend beyond the
backward position of the jack levers to a sufficient length to allow of small pieces
of brass iron or other metal being secured between the blades so as to keep the
blades properly spaced and make them to support one another. In this way the
comb will be as strong as though the blades and these small distance pieces were
all in one solid piece.

performed to be particularly described and ascertained in and by the following
statement:-
The object of this invention. is to give greater rigidity to the jack levers of
knitting machines to prevent their yielding sidewise when acted upon by the
incline or slur cock.
For this purpose I form each of the blades of the comb between which the jack
levers work with two projections to come on opposite sides of the line of travel of
the incline or slur cock, just sufficient space being left between the projections to
allow the incline or slur cock to pass freely. In this way each jack lever will
be supported at two points close up to that part of it which is acted upon by the
slur cock or incline as well as being supported at its tail end where it turns upon
a fixed pin carried by the comb. One of the projections above mentioned is at the
front end of each blade of the comb and this projection I extend beyond the back-
ward position of the jack levers to a sufficient length to allow of small pieces of
brass iron or other metal being secured between the blades so as to keep the blades
properly spaced and make them to support one another. In this way the comb
will be as strong as though the blades and these small distance pieces were all in
one solid piece.
The Drawings hereunto annexed shew the improvements above described.
Figure 1 is a side elevation of one lead or division of the comb and of the jack
levers working in it. Figure 2 is a back view of the same and Figure 3 a plan
view of the comb and slur cock.
In these figures A are the blades of the comb-B are the jack levers-C is the
Blur cock and D the pin upon which the jack levers turn.
A¹ A³ are the two backward projections on each comb blade A and A° are the
small metallic distance pieces between the end portions of the projections A¹ which
are beyond the backward position of the jack levers. One such piece A³ is secured
to one side of the projection A¹ of each plate A so that the spaces between the
back ends of all the projections are filled in and the projections abut one against
another as above explained.
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
1. Forming the blades of the comb between which the jack levers work with
two backward projections to come on opposite sides of the line of travel of the
slur cock to support the jacks on both sides of and close up to the alur cock
substantially as described.

backward position of the jack levers and filling in the spaces between the ends of
the projections so that the projections may support one another substantially as
described.
