Improvements in the Method of Securing or Fastening the Ends of
Solid Rubber Cords.
WILLIAM REGINALD READ WHITTY, 15, Basnett Street, Liverpool, Manufacturer
of Sporting Goods, do hereby declare the nature of this invention to be as
follows:-
The india or other rubber is stretched out thereby decreasing the thickness while
in this condition a short tube smaller at one end than the other made of metal
or other suitable material, is passed on to the rubber cord with the broader end of
the tube towards the end of the cord there is then left an aperture between the
shrunk rubber and the said tube into which is inserted circular tapering half tubes
or quarter tubes of wood or other suitable material which have their broad end
thicker and wider than the lower end-when the rubber is slackened it is prevented
going back to its original thickness owing to the pressure of the tubes-thereby
holding it firmly-in case of the rubber being square or flat the tubes would be
square or flat and probably contain two or four of the inner wood wedges.

Improvements in the Method of Securing or Fastening the Ends of
Solid Rubber Cords.
I, WILLIAM REGINALD READ WHITTY, of 15, Basnett Street, Liverpool, in the
County of Lancaster, Manufacturer of Sporting Goods, 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 reference to securing the ends of rubber cords to fastenings,
or means for holding such cords; and in securing or providing a fastening upon
the india-rubber or equivalent cord, the end of the cord is stretched out and the
thickness or diameter thereby decreased; while over the cord there is passed a short
tube or tubular device of metal, or other suitable material, smaller at one end than
the other, with the wider end of the tube towards the end of the cord. Then over
the end of the cord which is under stretch, and of decreased diameter, there is
provided or fitted circular tapering half tubes, or quarter tubes, of wood, or other

page_text: suitable material, the outside of which corresponds with the inside of the metal
outside tube or device; i.e. the broader end is thicker and wider than the small
end. Then if the metal tube or device be fitted over the wooden or other seg-
mental tubes (or vice versa), and the tension on the rubber is removed, then the
bore of the segmental tubes, being smaller than the normal diameter of the rubber
cords, this part of the cord end will be held and gripped under tension by these
tubes; and the parts behind and at the front of the tube will expand to their
normal size. By this means the rubber is firmly secured and held, in this secur-
ing or fastening device.
Of course, according to the form of section of the rubber, so will the fastening
device be made of corresponding form or shape to suit them.
The invention is illustrated in the drawings hereto annexed, in which Figure 1
is a longitudinal section showing the invention, and Figure 2 a cross section
at A. A., Figure 1; while Figures 3 and 4 are, respectively sectional elevation
and front end view showing a modified form of the parts employed.
Referring to the drawings, a is an india-rubber (or equivalent) elastic cord,
which may be of any suitable kind, say, such as that used for physical exercising
appliances, springs, and other appliances and devices, where strain is to be applied
to the ends of india-rubber cords. b is the tapered outside tube, which, say, is
of metal, or other suitable material. And c represents the segmental inner wooden
or other tube, the bore of which is of substantially less diameter--such as shown-
than the normal diameter of the cord a. The segmental tube c may be in two
parts, as shown in Figure 2, or in any other suitable number.
In applying the tubes b and c to the end of the cord a, the cord end is put under
tension, thereby reducing its diameter, say to at least that of the bore of the seg-
mental tube c, the tube b being first slipped over the cord. The parts of the
segmental tubes are then fitted over the end of the reduced part of the cord, and
the two parts c and b are brought into relative positions, shown in Figure 1; i.e. the
inside of the tube b will be brought to hear on the outside of the tube c. Then
the longitudinal tension on the cord is released, and the parts above and below the
ends of the segmental tubes c, expand out to their normal diameter, while the part
within it remains of the reduced diameter and under tension, and by its re-action
on the inside of this tube, makes a secure fastening with the tube.
To the outer metal or equivalent tube b, the handle, wire, or other fastening
means or attachment is secured. As for instance, as shown in the drawings, it
is provided with holes 61; through these holes a wire or pin may be passed; and
thus when the article is put into tension in use, the pull will be taken by this
wire or pin and tube b; which in turn holds the rubber by means of the segmental
tube c; and the neck of rubber under tension lying within this tube.
The method of securing illustrated in the modification shown in Figures 3 and 4
is, substantially, identically the same as that given in Figures 1 and 2; the only
difference being that the outside metal tube 6 is adapted to be held by a ring or
the like fitted under the flange 62 thereof, instead of by a through-wire, or pin,
as in Figure 1. In this connection it may be stated that the invention is in no
way restricted to the particular form of parts illustrated in the drawings.
By this method of securing, fastening, and holding of rubber cord, the rubber
is not so liable to cut or crack at the fastening, as happens with the methods of
fastening hitherto employed; and, consequently, the life of rubber cords, subject
to repeated stretching and reflexions, is considerably increased; furthermore, the
fastening is simple and inexpensive. And, in the case of the cord being damaged,
it can be repaired quickly.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :-
1. A fastening or mode of securing the end of rubber cords, consisting of the
employment of an outer rigid tube or tubular device, larger at one end than the

page_text: other, and an inner tube, such as described, having a bore of less diameter than
the normal diameter of the cord, and fitted over same; substantially as herein
set forth.
2. The fastening of rubber cords, particularly shown in and set forth with refer-
ence to Figures 1 and 2; and Figures 3 and 4, respectively, of the drawings.
