Improvements in Jacquard and like 'Machines employed in'Looms.
1, ROBERT HUTCHISON, Woodhead Street Dunfermline N.B., Machine* Maker
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:.
My invention is primarily applicable to cross-border Jacquard machines and the
like. The improvements are mainly to enable the needles to be operated upon at
either end, and to cause each upright wire to give spring in either backward
or forward directions to the needle which acts upon it.
The spring, which causes the needle to return to the position of rest after it has
been pushed in either backward or forward directions, is obtained from the upright
wire as shown in the accompanying drawings A Figs. 1. 2. & 3. The hooked
end B of the upright wire A rests upon a fixed "split" or cross-rod C (section
shown Figs. 1. 2. & 3.); and a cross-rod D (section shown) is placed inside the
doubled portion of the upright wire about half an inch from the bottom. Cross-
rod D steadies the upright wire while leaving it free to be pressed back, and also
assists the upright to spring forward again to its normal position. Both of
the cross-rods C and D run through one entire row of upright wires from side
to side of the machine: each row of wires is similarly furnished with these rods.
A frame, indicated by E Figs. 1. 2 & 3, into which all the cross-rods D are fixed,
is connected with the lifter and consequently rises and falls with it. To guide and
keep in position the upright wires, a wire frame is fixed below the brander splits
(section shown N Figs. 1. 2. & 3.) having its wires running from front to back of
the machine: one of these wires is shown F Figs. 1. 2. & 3.
The needle GH Figs. 1. 2. 3 & 4 has an oval-shaped eye or loop J Figs. 1. 2. 3.
4. & 5. turned upon it to form the socket in which the reversing pin or lever K
Figs. 1. 2. 3. & 5. rests. This lever is made of wire flattened at the top where it
is to press against the upright wire A and doubled at the bottom to fill the eye J
which it goes quite through to prevent the needle from turning.
To keep
the lever from coming out of the socket, a knee L Figs. 1. 2. 3. & 5. is bent upon
it just below the guiding wire F. Figure 5 shows this knee on the lever (front
view). Figure 4 shows the eye J of the needle looked at from above.
The needles can be acted upon by the cards at either end, the effect upon
the upright wires being the same. Thus, when the needle is pressed in at the front of
the machine at G Figs. 1. 3. & 4. the loop J of the needle presses back the upright
wire (the outside end of the loop being flattened to secure accurate pressure
as shown in Fig. 4). Figure 3 shows this movement resulting from pressure upon G.
Or, when the needle is pressed in from the other end H Figs. 1. & 2. the foop J
of the needle carries forward with it the bottom end of the lever K Figs. 1. & 2.
which, pressing against a cross-rod M (section shown Figs. 1. & 2.) as a fulcrum,
causes the top end of the lever to press back the upright wire as before. This
movement is shown in Fig. 2.
Figure 1. is a view of the needle and upright wire in a position of rest.
The needle and upright wire as described above are applicable to double-action
or cross-border double-action machines and also to single-action machines.
