COMPLETE SPECIFICATION.
Improvements in Embroidery and Embroidering Machines.
I, JOHANN RUCK DESCHEL, of Plauen, Saxony, in the Empire of Germany,
Manufacturer, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:―
The object of my invention is to effect improvements in ornamenting woven and
other fabrics, by means of looped braiding.
In carrying out my invention I make use of a specially formed apparatus, which
attaches the braid to the fabric as it is formed; the braid consisting of two
threads, of similar or different colors, and of similar or different thicknesses;
formed in loops and passed through the material, and secured on both sides of the
same.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings in which similar figures of
reference indicate corresponding parts.
Fig. 1 is an elevation of the apparatus, partly in section.
Fig. 2 is an enlarged section on the line 1-2 of Fig. 1.
Figs. 3, 4, 5 and 6, are detail sections, drawn to a still larger scale, illustrating
the operations of the hook, looper and threads.
Fig. 7 is an illustration of the ornamented fabric.
3 is the driving pulley, mounted upon an axle 4; the framing resembling that of
a sewing machine. 5 is a toothed wheel carried by the axle 4 and revolving
therewith. 6 is a toothed wheel fitted with an eccentric 7. The wheel 5 drives
the wheel 6, at half the number of revolutions of the wheel 5. 8 is the eccentric
rod which drives the lever 9, pivoted at 10. The lever 9 is fitted with pins 11
which work in a groove in the ring 12. The reciprocating motion of the lever 9
raises and lowers the ring 12. 13 is a slotted vertical tube sustained by the
cloth plate 14. The tube 13 is fitted with a bevel wheel 27, in
the bevel wheel 28 fast on the shaft 29. This shaft is connected to the feed
with
gear
directing handle 26 by means of the bevel wheels 30 and 31.
15 is a nut fitted inside the tube 13, which nut rises and falls with the ring 12, by
means of the screw 16, sliding in one of the slots in the tube 13. 17 is the looper
tube, having a large bore nearly to the top, where the bore is reduced to act as a
guide to the hook 18. Two diagonal holes are formed in the upper end of the
looper 17, as shown in Figs. 3, 4, 5 and 6, through which the two threads 19 and 20
are carried, the threads being supplied by the spools 21, 22.
The looper tube 17 is provided (externally) with a quick threaded screw, the
liding nut 15 being cut to fit the same.
23 is the stitch plate, having a hole through which the hook 18 passes, and
hrough which also the threads 19, 20 are guided in their progress to the fabric 24.
The operation is as follows:-The threads 19 and 20 being carried from the
pools 21, 22, through the looper tube 17, up to and led through the diagonal holes
o the outside of the looper, and thence through the stitch plate 23 to the underside
f the fabric 24, and adjusted by bringing down the hook 18, and using the
andle 26; the position of the threads is that shown in Fig. 3. The reciprocating
ction of the lever 9 raises and lowers the collar 12 and nut 15. The nut 15 being
revented from revolving by the screw 16, its motions cause a partial revolution of
he looper 17.
When the hook 18 passes downwards, through the material 24 to the position
hown in Fig. 3, the partial revolution of the looper lays the thread 19 round the
em of the hook 18. On the rising of the hook to the position shown in Fig. 4, the

page_text: hook takes up the thread 19, forming a loop therewith above the material. This
loop is then held up by the hook (Fig. 4) while the material 24 is moved by the
presser foot 25; after which motion the hook 18 descends, as shown in Fig. 5.
The looper 17 is then turned in the opposite direction, as also shown in Fig. 5.
The hook then engages with the thread 20, and draws the loop of the same thread
through the previous loop of the thread 19. The presser foot 25 retains the loops
in position as they are formed, the fabric being guided as required. The hook 18
is worked by the machine in the same manner as the needle in ordinary sewing
machines.
In Fig. 7 the finished fabric is illustrated.
By using threads of different strengths, a festooned braid is formed, each loop
formed by the strong thread being fuller and more puffed than that formed by the
weaker thread.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved method of braiding fabrics substantially as herein before
described and illustrated by the drawings.
2. The improved apparatus for braiding, consisting of the combination of the
looper 17, mounted in a tube 13, and caused to partially rotate in opposite directions
by means of a threaded nut 15 acting upon the screw thread formed upon the looper
tube 17, substantially as herein before described and illustrated by the drawings.
3. In apparatus as aforesaid, the combination of the wheels 5 and 6, the
eccentric 7, eccentric rod 8, lever 9 and ring 12, operating the nut 15 and looper 17,
substantially as herein before described and illustrated by the drawings.
4. The general arrangement, construction and combination of the several and
respective parts, together constituting my invention of Improvements in looped
braiding, and in apparatus therefor, substantially as herein before described and
illustrated by the drawings.
