COMPLETE SPECIFICATION.
Improvements in Tyre Fasteners.
We, ALFRED CONINGSBY of 228 Flatbush Avenue, Brooklyn in the County of
Kings and State of New York, United States of America, Manufacturer, and
GEORGE HERBERT POTTER of 280 Lafayette Avenue, Brooklyn, in the County
of Kings and State of New York, United States of America, Musician, 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:—
The invention relates to improvements in devices for securing tyres to wheel-rims,
one object being to provide a device which will enable the tyre to be quickly
secured to, or removed from, the rim, and a further object being to provide a device
which may be easily applied to the rims of tyres now in use, without any great
changes in construction, or any great amount of expense.
A practical embodiment of the invention is represented in the accompanying
drawings, in which—
Fig. 1 is a side view, partially broken away, of a wheel rim and tyre, the tyre
being shown as fastened to the rim by two of the improved securing devices;
Fig. 2 is a cross section of the same, on the line x, x;
Fig. 3 is a side view of a wheel rim and tyre, the tyre, in this instance, being
shown as fastened to the rim by a single securing device.
Fig. 4 is a cross section of the same, on line y, y; and
Fig. 5 is a cross section through a tyre and rim, showing the manner of applying
the securing device to a tyre in which the attaching wires are imbedded in the edges
of the outer cover or shoe.
A designates the wheel rim; B is the outer cover or shoe; and C is an inner or
air tube of the tyre, which is secured to the rim A by the improved securing
device.
Two attaching or securing wires D, D' extend along the inner wall of the outer
shoe B, between the shoe and the air tube C. These wires are provided with bent
portions d, d', which extend through elongated slots b, b in the outer cover or shoe,
and through elongated slots a, a' in the rim A.
The ends of the attaching wires extend through the shoe B, and through
openings a' in the rim A. The ends of the wires are enlarged to form heads d², so
as to cause the heads to form abutments to prevent the withdrawal of the
attaching wires, when they are drawn snugly against the inner wall of the shoe.
For the purpose of tightening the attaching wires, we provide a screw bolt E,
which has a travelling nut F thereon, which nut engages the bent portions d d', so
that as the screw bolt is screwed up, the travelling nut is drawn away from the
rim A, drawing the bent portions of the attaching wires with it. To do this, we
preferably provide the travelling nut with two arms ff', extending laterally there-
from, and provided with slightly enlarged or turned-up ends, to retain the bent
portions d d' thereon.
A bearing plate G is preferably placed upon the rim A, for the screw bolt E to
turn upon, for the purpose of preventing the bolt E from injuring the rim.
We preferably secure the tyre in position by means of two of these securing
devices, but we may only use one, as shown in Figs. 3, 4, and 5, in which case each
of the attaching wires preferably extends around the entire circumference of the
inner wall of the outer tube, and is secured at its ends through a single opening a³
in the rim.

page_text: In the tyre shown in Fig. 5, the attaching wires are imbedded within the edges of
the outer cover, but it will be seen that they may be drawn up into position to lock
the tyre to the rim, as well as where the attaching wires are separate from the
cover.
When it is desired to secure the tyre to the rim, the outer cover or shoe, with its
inner tube therein, is placed along the circumference of the rim, and the attaching
wires are inserted between the inner wall of the shoe and the exterior wall of the
air tube, through a suitable slit 2, the ends of the wires being pushed through the
openings a² in the rim, and the bent portions d, d' inserted through the elongated
slots in the outer cover and the elongated slots a, a' in the rim. The bent
portions are then swung over the arms, of the travelling nut F. The screw
bolt E is then screwed up, causing the travelling nut F to recede from the rim,
drawing with it the bent portions d, d', and causing the attaching wires to draw the
outer cover or shoe snugly against the rim.
To release the outer shoe, the screw bolt E is unscrewed, causing the travelling
nut F to approach the rim, until the bent portions of the attaching wires can be
swung out of their engagement with the travelling nut, thereby releasing the
attaching wire's engagement with the outer covering.
The openings a in the rim are preferably provided with narrowed extensions, so
that after the heads of the attaching wires are inserted through the openings, the
wires may be drawn up until the heads cannot be withdrawn from the said
openings.
We may use several of these securing devices along the rim, if so desired, and
will have it understood that slight changes might be resorted to in the construction
and arrangement of the of the several parts, without departing from the spirit and
scope of the invention; hence we do not wish to limit ourselves strictly to the
construction and arrangement herein set forth.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination with the wheel rim, of tyre-fastening wires extending along
the exterior of the rim, and provided with bent portions extending inwardly through
the rim, and a wire-tightening device comprising a movable piece engaged with the
bent portions of the wires at the inner side of the rim, and means for moving the
said movable piece away from the inner face of the rim, to tighten the wires,
substantially as set forth.
2. The combination with the rim of the wheel, of tyre-fastening wires extending
along the outer face of the rim, and provided with bent portions extending through
the rim, and a wire-tightening device comprising a travelling nut engaged with the
bent portions of the wires at the inner side of the rim, and a screw engaged with
the nut and having a bearing against the inner face of the rim, substantially as .set
forth.
