Improvements in Apparatus for Sewing or Forming Loops on
Cloth and the like.
I, LEVY LUBLIN, of 29 Drottninggatan, Stockholm, in the Kingdom of Sweden,
Merchant, 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 has for its object to arrange the apparatus used for sewing or
forming loops on cloth in such a manner, that the working parts will be effectively
guided and the needle and spring readily exchanged and adjusted.
As is well known, such an apparatus consists of two parts, serving as handles
and movable along each other, one of the said parts holding the needle, while to the
other is secured a spring, which while the needle is on its upward motion after
pushing down the yarn through the cloth, retains the yarn in its proper position, so
that a loop can be formed. Of late, there has been inserted between the two parts
a plate, at the lower end made in the shape of a tube, which surrounds and guides
the portions to which the needle and spring are attached. For adjusting the
length of the stroke of the needle, that is to say the size of the loop formed by
the yarn, there has been used a screw, which is pushed through the plate at any
Euitable point and serves as a stop by being brought into contact with projections
or lugs arranged in the two parts above mentioned of the apparatus, the motion
of which is thus limited.
This arrangement, however, does not sufliciently facilitate the manipulation of
the apparatus, which for this reason is constructed in the manner hereinafter
described.
In the accompanying drawing I have illustrated an apparatus, arranged in
accordance with my invention.
Figure 1 is an elevation partly in section of the improved apparatus.
Figure 2 is a similar view with the parts in a different position.
Figure 3 is a side-view of the same.
Figure 4 is a side elevation partly in section showing a modified construction of
the apparatus and
Figure 5 is a side-view of the same.

In the apparatus illustrated in Figures 1-3, a and bare handle pieces to the
inner edge of each of which is fixed a tube or respectively which at their lower
ends are cut off longitudinally and provided with a number of holes 1, 2, 3, 4, placed
at different heights, the said tubes being arranged to slide one within the other.
The needle c and spring d are fastened by means of adjusting-screws c' and ',
tapped into any of the above-mentioned holes, according as the needle and spring
are required to project more or less beyond the tubes, that is to say, according as
loops of greater or less length are desired in the work.
One of the said tubes is larger in diameter than the other, so that the latter may
be inserted into the former and may be guided by it in its up and down movement.
To allow the adjusting-screw e', belonging to the inner tube, to pass through the
side of the outer tube, the latter is provided with a longitudinal slot X in which this
screw moves while the apparatus is at work. The motion of the two parts is
limited partly by a stop-screw y, which is screwed into the outer tube and against
which the upper end of the needle strikes in the upward movement, and partly by
the projecting edge or stop on the tube g in which the needle is secured, against
which stop the spring strikes when the corresponding part of the apparatus is drawn
upwards.

page_text: An apparatus constructed on this principle is easily taken apart and put together;
it has a steady motion and admits of the needle being exchanged and re-adjusted
with little trouble and loss of time.
It should, perhaps, be added that in apparatus of this class the needle and spring
have previously been secured to corresponding parts of the handle-pieces by means
of screws inserted into holes placed at different heights, but these screws have not
as in my improved apparatus been accessible from the outside; when the screws
are put in from the inside of each handle-piece, it is necessary to take the whole
apparatus apart, when a rendjustment of the needle is to be effected, which is not
required when the screws are accessible from the outside as in my improved
apparatus.
In the modified construction, shown in Figures 4 and 5, the circular section of
the tube is changed into a square or rectangular one, this tube thus forming a
kind of gutter, while a flat straight bar is substituted for the other tube y.
screwy is replaced by a lug inserted in the interior of the gutter.
The
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 1
claim is :-
1. An improved apparatus for sewing loops on cloth consisting of two handle-
pieces (a, b) movable up and down along each other and at their inner edges
provided with tubes (9) respectively, one of the said tubes surrounding and
guiding the other and provided with an adjustable needle (c), an adjustable
spring (d), being attached to the other tube; substantially as specified and
illustrated in the drawing.
2. The modified form of apparatus consisting therein, that the outer tube is of
nu angular section and the inner tube replaced by a flat bar.
