Improvements in or connected with the Rollers of Frames for
Spinning Flax.
We, JOSHUA VALENTINE EVES, of Forth River Mill, Falls Road, Belfast, in
the County of Antrim Ireland Mill Manager and MALCOM MACGREGOR GREEVES,
of Forth River Mill, aforesaid, Mill Manager, 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:-
This invention is designed to so construct the axles of the pressing rollers of flax
spinning frames or to make such additions or attachments thereto, that will render
it impossible for the attendant to "piece up an end" when broken in the manner
known as over the roller." This form of piecing can only be made when the end
of yarn can be passed between the ends of the roller axles. The objection to
piecings or joinings in the yarn being made in this manner is that the piecing or
join is very long and thick, and may carry with it some of the lap off the roller
causing very unsightly and objectionable faults in the cloth.
The invention is applicable to such spinning frames where the saddle bush
controls the tendency to longitudinal or endwise movement in the roller axle, and
consists in the combination with the pressing roller axle of a device to fill up or
bridge over the space between the ends of two adjacent axles so as to prevent the
passage of the thread of yarn between them, without interfering with the free and
independent rotation of the rollers.
The invention may be carried out in several ways, and it will be fully described
with reference to the accompanying drawings in which several examples are shown,
the figs. being front and side elevations of the pressing rollers and pressing roller
axles.
Referring to Figs. 1 and 2 we construct the axles A of the rollers B with an
elongation or projection a at one end, which will extend beyond the screw threads
that receive the nut C, and we place these axles in position so that there will be
alternately a long and short end. On the long end is placed an ordinary nut C
but on the short end we mount a hollow nut D the edges of which embrace and
overlap the projecting end a of the adjacent axle. Clearance is allowed between
the axle ends so that in the putting in or taking out of the rollers the axle may be
moved or pushed along end wise, so that the projecting end may free itself from the
edges of the hollow nut which overlap.
Referring to Fig. 3 a modification is shown in which instead of the projecting
end a of the axle A shown in Fig. 1 a nut C with projection c is substituted,
the projection c of the nut C¹ passing into the hollow of the nut D.
Referring to Fig. 4 we fill up the space between the ends of the axles A by a
spring E of U or other convenient shape. The spring E is preferably made of
wire with the points e bent to fit into the centre holes in the ends of the axles.
The spring E may revolve with the axles or may be long enough to rest against
some portion of the roller stand or frame.
Referring to Figs. 5 and 6 a flat steel spring F connects or fills up the space
between the axle ends. In the spring are punched two holes f which fit over and
rest upon the ends of the axles.
Referring to Fig. 7 the space between the ends of the axles A we fill up by a
spiral or coiled spring G the end coils of which pass over the axle ends.
Referring to Fig. 8 the space between the roller ends is filled up by a spiral

page_text: spring H of less diameter than the spring G. The ends of the spring are turned or
bent outwards so as to engage with the centre holes in the ends of the axles.
Referring to Figs. 9 and 10 we form a connecting piece J of wire or other
material with a loop j at each end to fit over the ends of the axles, this can be
placed in position to fill up the space between the axles as the rollers are being put
in their place.
It is evident that these devices may be modified if desired to meet any special
requirement of the spinning frame to which they are to be applied.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a frame for the wet spinning of flax yarn, the combination with the pressing
roller axles of a device for filling up, or bridging over the space between the ends,
or connecting the ends of adjacent axles, to prevent the passage of yarn between
them substantially as described.
2. In a frame for the wet spinning of flax yarn the combination with pressing
roller axles of a projection on the end of one axle, and a nut with overhanging
edges on the end of the adjacent axle, the one overlapping the other to prevent the
yarn being passed between them and consequent piccing up over the roller
substantially as described.
3. In a frame for the wet spinning of flax yarn the combination with the pressing
rollers of a spring piece or its equivalent inserted between the axle ends to fill up
or bridge over the space for the purpose specified substantially as described and
illustrated in either of the Figs. 4 to 10 of the drawings.
