For the application to Warp machines of Two or more seperate and independent
presser slides, or bars.

page_text: with curved slots B¹ C₁ and are kept slightly apart by the insertion of a washer D in
cach slot, these washers prevent either bar bearing upon the other and thus secures
independent action. A front view of a washer D is shown at Figure 2. The number
of slots in each bar will depend upon the length of the bar. A front view of the
slotted left ends of the two bars B and C in position on the usual presser bar A is
shown at Figure 3.
And the right and left slotted ends of each bar are shown in front view at Figures 4
and 5 the intermediate portions indicated by the dotted lines depending upon the
length of the bars. A stud E is passed into a flat washer and through a seperating
washer D in the slots of the bars B and C and is then firmly screwed into the usual
presser bar A, there being as many studs and flat washers as there are slots in one of
the sliding presser bars.
When three or more sliding presser bars are employed they are kept apart by
seperating washers, and longer studs E are employed to secure them to the presser
bar A. When a series of two or more sliding presser bars are employed each having
the curved portion of the slots at the right end, each bar is drawn to the right by a
spring having its outer end attached to a rod or bracket secured to the framing of the
warp machine, its inner end being attached to the bar or to a link secured to the bar,
such movement places the sliding presser bar in its lowest position so that the lower
edge of each projecting portion at the bottom of the bar presses one or more needles,
the needles lying between the projections are not pressed by the bar.
The bar C is shown at its lowest position at Figures 1 and 3, the bar B being shown
out of work. When the curved portion of the slots are at the left end the positions of
the springs and Jacquard are reversed.
The left end of each sliding presser bar is hooked to the slide of a dropper ox
operated by a jacquard of the usual construction. The droppers regulate the position
of the bar within the length of the straight portion of the slots.
In the drawings broad projections are shown on the lower edge of the sliding presser
bar B and narrow ones on the bar C. But I do not confine myself to such shaped
projections or their positions as I may form them of equal or unequal lengths so that
when two or more sliding presser bars are at their lowest position the whole of the
needles in the machine will be pressed at each course or only portions of them, or either
or the whole of the sliding presser bars may be drawn up clear of the needles for one
or more courses by the operation of the jacquard.
The above described arrangement and employment of two or more independent
slide pressers or sliding presser bars I employ when making fancy shawls or other
fabrics which require one or more adjacent needles to be pressed in one course while
the next one or more adjacent needles are not pressed so that such impressed needles
may retain their loops during one or more courses according to the operation of the
jacquard to form the pattern required.
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 :—
The employment of two or more independent slide presses or sliding presser bars
substantially as described and illustrated in the drawings annexed.
