Improvements in Connecting Hollow Machine Belting.
We, CASPAR JOSEPII CAMENZIND and BERNHARD BUTTLER, both of Gersau,
Switzerland, Manufacturers, 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 relates to an adjustable connection free from knots and joints
and suitable for hollow machine or connecting belting such as are especially used
in spinning and doubling machines; however they may also be used for other
purposes.
The purpose of the invention is thus principally to produce such a transmission
or spindle driving cord having a connection which is free from knots and joints
and which can be adjusted easily so as to allow the cord to be lengthened or
shortened and which connection is also self securing.
Such a connection is shown in the annexed drawing, in Figs. 2 and 3 in forms
of construction represented as examples whilst Fig. 1 shows the manner, in which
the two free ends of the string made of elastic braided material in tubular form are
connected together in the most convenient manner.
The connection is made by the one end of the string being drawn for a certain
length through the hollow part of the other end and then drawn out laterally
through the material.
This connection is produced in the following manner.
The cord is first measured to the length required and at one end a its diameter
is diminished by removing the one half of the threads of the material; this
diminished end is then pulled through the eye of a needle c (Fig. 1) and by means
of the latter it is drawn for a certain length through the hollow space in the other
end of the cord and then laterally out through the material. The length of the
connection is measured and determined according to the strength and the drawing
power of the cord.
The securing of the connection is effected by stretching the end b and is produced
by the elasticity and the structure of the hollow cord, the diameter of which
becomes smaller by pulling on it, the meshes of the braided cord coming together
in the direction of the longitudinal axis of the cord. By pulling the meshes of
the end b back the diameter becomes larger as the meshes expand; the enclosed
end thus becomes free and the cord can be stretched or shortened at pleasure.
In order to prevent during the use of the cord back pulling of the surrounding
end b, the running direction is preferably to the end a. In gearing running
alternately to the right and to the left a double connection is made in an analogous
manner. For this purpose the string is pointed at both ends and the latter aro
pulled with a needle laterally into and in opposite directions through the hollow
space for a certain distance and then laterally out through the material Fig. 3.
For heavy strains the drawing power of the cord can be increased and its
elasticity can be diminished by cutting off a double length of cord and by pulling the

page_text: one end through the whole length of the cord so that both ends are lying opposite one
another, a smooth connection is thus obtained and the cord is doubled throughout.
Having now. particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. An improved adjustable connection free of knots and joints for hollow
belting made of hollow cords, in which the one end a of the cord is pulled for a
certain length through the other end b and then laterally through the texture
so that by pulling the texture of the surrounding end back the enclosed end a
becomes free and the cord can be shortened or lengthened at pleasure, whilst by
pulling the cord the diameter of the surrounding end is diminished and the
enclosed end is held with corresponding force.
2. An improved adjustable connection free of knots and joints for hollow belting
made of hollow cords in which both ends a and b are pulled in an opposite direction
laterally into the hollow space of the cont a certain way through the latter and
again laterally out of the same such cords being suitable for gearing moving
alternately to the right and to the left.
