Improvements in or connected with Caps for the Ends of Loom
Lathes.
I, JACOB JUCKER, of 60, Peter Street, Manchester in the County of Lancaster,
Mechanical Engineer, 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 relates to the caps for the ends of loom lathes and consists in the
arrangements of adjustable slides on such caps for holding and adjusting the outer
end of the picker spindle. Hitherto the caps have been made with a round hole only
through which the picker spindle is passed and its outer position is fixed thereby.
This has the disadvantage that as different pickers practically always differ in the
length of the foot and shank from their spindle holes, the foot of the picker may not
enter sufficiently into the groove in the bottom of the shuttlebox, or enter it too far, in
which case it has to be cut, and in either case the shuttle does not strike the picker
fairly in the middle of the shank, which causes the pickers to be rapidly worn out and
produces bad weaving.
The object of my invention is to remedy these defects by making the picking
spindle adjustable either vertically and horizontally, or vertically only as may be
desirable for the kind of picker and loom used, which I effect by holding the spindle
in slides adjustable on the cap.
On the sheet of drawings appended hereunto fig. 1 shews a front view of the
shuttlebox end of a loom lathe with my improved cap attached.
Fig. 2. an end view of the cap.
Fig. 3. a vertical, an fig. 4. a horizontal, section of the same.
In fig. 1. a represents the end of the lathe bottom, to which the cap bis fixed
by a screw c as usual. The inner end of the picker spindle d is carried as usual in
a bracket which is vertically adjustable. The lower part of the cap 6 has webs or
ribs 6¹ fitting over the end of the lathe bottom a. In the upper part the cap is formed
with an opening 62 and a rectangular recess on the outer side, into which a rectangular
slide g is fitted. This slide is formed with a vertically oblong slot g and is hori-
zontally adjustable by means of a screw k tapped into the slide and held by collars in
an open slot of the rib 63 of the cap, as shown by figs. 2 and 4.
On the outside of
the cap I arrange another slide h, the upper part of which is tapped by a screw i.
The latter can turn in the lug 6 cast on the cap, being held by a shoulder on the
screw and a washer rivetted to the end. The slide has an oblong horizontal
slot 2, and a vertically oblong slot h³ for the screw c. The picker spindle d is held in
the square formed by the crossing of the slots h² and g¹, and can be adjusted hori-
zontally by shifting the slide 9 by means of the screw k and vertically by shifting the
slide h by means of the screw i, the screw c being slackened at the time. When
adjusted, the slide g is fixed in its position by a lock screw m or the surface of slides. g
and h in contact with one another may be finely serrated with vertical serrations
fitting into one another for this purpose. The slide and the spindle spring / are
fixed in their positions by tightening the screw c.
g
In some cases where horizontal adjustment is not required, I omit the slide 9 and form
the cap 6 without a recess for the same and only use a vertical slide.
This may be
arranged exactly like the slide herein before described and a vertical slot of the width
of the picker spindle formed in the cap b, or the cap may be formed with a larger
opening and the slide with a round hole for the picker spindle instead of the oblong
slot h³.

page_text: 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
Firstly, for holding the outer ends of picker spindles in one or two slides adjust-
able on the lathe end caps substantially as hereinbefore described.
Secondly, the combination with the cap fixed to a loom lathe end of a horizontally
adjustable slide with a vertically oblong slot and a vertically adjustable slide with a
horizontally oblong slot for holding the outer end of the picker spindle, substantially
as herein before described and illustrated by the drawings.
Thirdly, the combination with the cap fixed to a loom lathe end of a vertically
adjustable slide holding the outer end of the picker spindle, substantially as herein-
before described.
