Improvements in Fastening Devices for Pneumatic Tyres.
I, MARTIN DIEDERICH RUCKER, of 32, Holborn Viaduct, in the City of
London, General Manager to Humber & Co., Limited, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the means for securing what are well-known as pneumatic
tyres upon wheels.
•
In carrying out the invention I employ a wire, cord, or equivalent which passing
round a portion of the tyre secures it upon the rim. The details may vary, but the
following description will serve to disclose the salient features.of the invention.
In employing a wire, cord, or equivalent it is necessary to draw it tight around
the tyre and rim and to maintain it so and I prefer to place the wire upon or
through a bead or projection formed upon the edge of the cover or tyre, though
the wire may be passed through or over any other suitable portion of the tyre.
Each end of the wire is provided with a hole, the ends of the wire preferably
nearly meeting and a small lever having pins one on each side adapted to engage
with the holes in the wires is placed between them. If desired this arrangement
may be reversed, the holes being in the lever and the pins upon the wires. In one
position the wires are slack a suitable distance say conveniently three sixteenths of
an inch. existing between the two pins upon the lever; when therefore the lever is
turned over so that those pins occupy respectively the opposite positions to what
they did at first the ends of the wires will be drawn past each other and the wire
will thus be strained, the hoop formed by it being then three eighths of an inch
shorter than it was before and smaller in diameter accordingly. It is not really
necessary to provide any special means for fixing the lever in position after the
wire is strained, but to avoid the possibility of the fastening coming loose I may
provide means for that purpose. A convenient way of effecting this is to provide
a short screw upon a suitable part of the lever and allow this to pass through a
corresponding hole in the tyre and then screw a nut upon it, thus securing the
lever. A spring or other equivalent device may however be employed for the
purpose, say a split pin passing through a hole in the pin on the lever.
Generally 1 p efer to have two of these hoops one for each edge of the cover and
placed outside beads upon the cover, and to place both beads or wires in suitable
channels or gutters formed around the rim.
Conveniently a flat metal or other band may be employed but round or other
shaped wires or the like may be used in which case flat ends may be provided or
the ends may be formed into loops.

COMPLETE SPECIFICATION.
Improvements in Fastening Devices for Pneumatic Tyres.
I, MARTIN DIEDERICH RUCKER, of 32 Holborn Viaduct, in the City of
London, General Manager to Humber & Co., Limited, 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 the means for securing what are well-known as pneumatic
tyres upon wheels.

page_text: In carrying out the invention I employ a wire, cord, or equivalent which passing
round a portion of the tyre secures it upon the rim.
In employing a wire, cord or equivalent it is necessary to draw it tight around
the tyre and rim and to maintain it so and I prefer to place the wire upon or
through a bead or projection formed upon the edge of the cover or tyre, though
the wire may be passed through or over any other suitable portion of the tyre.
Each end of the wire is provided with a hole, the ends of the wire preferably
nearly meeting and a small lever having pins, one on each side adapted to engage
with the holes in the wires, is placed between them. If desired this arrangement
may be reversed, the holes being in the lever and the pins upon the wires. In one
position the wires are slack, a suitable distance, say conveniently three-eighths of an
inch, existing between the two pins upon the lever; when therefore the lever is
turned over so that those pins occupy respectively the opposite positions to what
they did at first the ends of the wires will be drawn past each other and the wire
will thus be strained, the hoop formed by it being then three-quarters of an inch
shorter than it was before and smaller in diameter accordingly. It is not really
necessary to provide any special means for fixing the lever in position after the
wire is strained, but to avoid the possibility of the fastening coming loose I may
provide means for that purpose. A convenient way of effecting this is to provide a
short screw upon a suitable part of the lever and allow this to pass through a
corresponding hole in the tyre and then screw a nut upon it, thus securing the
lever. A spring or other equivalent device may however be employed for the
purpose, say a split pin passing through a hole in the pin on the lever.
Generally I prefer to have two of these hoops, one for each edge of the cover
and placed outside beads upon the cover both beads or wires being in suitable
channels or gutters formed around the rim.
Conveniently a flat metal or other band may be employed but round or other
shaped wires or the like may be used in which case flat ends may be provided.
In the accompanying drawings:
:-
Figure 1 is a perspective view of a device constructed according to this invention,
showing the two ends of the band in the position they may occupy when just about
to be connected together or when just disconnected.
Figure 2 is a side elevation showing the device as when drawing the two ends
together and
Figures 3 and 4 are respectively a side elevation and plan showing it as when
the band is tightened.
Figure 1 is drawn to a larger scale than Figures 2, 3 and 4.
Figures 5 and 6 show modifications.
Like letters indicate like parts throughout the drawings.
A are the two ends of the band to be connected together and B is the lever
which together with the cross-bars B¹ B² may conveniently be stamped in one piece.
The cross-bars B' B² extend across the forked or open end of the lever B and by
the former of them viz. B¹ (shown only in dotted lines in the accompanying drawings)
the lever B is hinged to one end of the band A this end for said purpose being bent
around the cross-bar B' as shown at A¹.
The other end of the band A is hooked as at A2 so that it may be engaged with
the cross-bar B2 of lever B. The band ends A and lever B are bent so that when
folded together in the manner shown in Figures 3 and 4 they may occupy the least
possible space.
To tighten the before described device upon the cover or tyre, the hook A² is
engaged with B2 when the lever B is in a position such as shown in Figure 1. The
lever B is then pulled over in the direction indicated by the arrows in Figure 2
with the result that the ends A' A² are first moved up to and then past each
other.
In Figures 5 and 6 the principle of operation is exactly the same as that already
described but instead of making the lever in the form of a fork as in Figures 1 to 4
the lever consists of a flat bar with the bars B' B' extending one on each side and

page_text: the ends of the wire or band A, which in this instance may conveniently be a round
wire flattened and perforated so as to fit over the bars. The band A is tightened
up exactly as before and the lever B is provided with a screwed pin or projection B4
adapted to pass through a hole C2 in the rim C and to receive a nut B35 for the
purpose of securing it firmly in position. In all these figures either or both ends
of the band may be made detachable from the lever or if preferred neither end may
be detachable; as a rule I find it preferable to have one end a fixture and the
other detachable as the lever is then not liable to be lost while the band can be
conveniently and entirely removed from the wheel.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a band fastener for securing the covers of pneumatic tyres to the wheel
rims the employment of a lever such as B engaging both ends of the band and
drawing them together in such a manner that neither end of the band slips or
slides upon the lever substantially as described and illustrated in the accompanying
drawings.
2. In a band fastener for securing the covers of pneumatic tyres to the wheel
rims the tightening of the band by means of a lever engaging both ends of the
band and operating to draw them together in such a manner that neither end of the
band slips or slides upon the lever substantially as described and illustrated in
the accompanying drawings.
3. In a band fastener for securing the covers of pneumatic tyres to the wheel
rims the combination with the band of a lever such as B engaging both ends of the
band and adapted when turned over to draw the two ends of the band towards and
past each other neither end of the band slipping or sliding upon the lever and the
whole folding down snugly together substantially as described and illustrated in the
accompanying drawings.
4. In a band fastener for securing the covers of pneumatic tyres to the wheel
rims the combination with a lever such as B and screwed pin such as B of a nut B³
substantially as and for the purpose described and illustrated in the accompanying
drawings.
