Improvements in the Method of and in Means for Securing the
Covers of Pneumatic Tyres to the Rims of Wheels.
I WALTER PILLING of 107 Hough Lane, Eagley, near Bolton, in the
County of Lancaster, Cycle Agent, 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 and accompanying drawings:
:-
My said invention relates to improvements in the method of and means for
securing the covers of pneumatic tyres to the rims of wheels generally, but more
particularly to the light rolled rims used in the construction of velocipede wheels.
The improvements will be more clearly understood by referring to the annexed
sheet of illustrative drawings.
Fig. 1 is a cross sectional view of the well known "solid" cycle rim, that is to
say a rim of a single thickness of metal, fitted with part of the means constituting
my invention.
Fig. 2 is a longitudinal section of Fig. 1.
Fig. 3 is a plan view of the rim.
Fig. 4 is a cross section of the rim with the inflated air bag and cover applied.
Fig. 5 is a view of a portion of the cover showing the protruding wires which
are placed in the edges of the cover.
Fig. 6 is a view showing the cover and rim together as in Fig. 4, and the
protruding side wires hitched to the anchor blocks on the rim.
Fig. 7 is a view of the ordinary hollow rim to which my invention is also
applicable.
t
Referring to the first mentioned Figs. 1 to 3, I fix in the hollow of an ordinary
solid rim a two anchor blocks 6 6' which are simply pieces of metal securely fixed
in the rim by rivetting, brazing or any other suitable mode. In one side of the
said blocks I bore holes c, the holes in the block b looking away from the holes in
the block as clearly seen in Fig. 3. The wires d d are contained in the edges
of the pneumatic cover e and each wire forms a complete ring or it might be two
ring laps the loose ends of which cross and overlap at the point where they
protrude from the edge of the cover, as plainly shown at Fig. 5. The loose ends
of the wires d d' are formed with hooks d which engage with the holes in the
anchor blocks as clearly shown in Fig. 6. The blocks bb' may be from
12 to 20 inches apart on the rim so that the loose ends of the wires d'd' overlap
each other for from 6 to 10 inches each. In applying the cover before the inflation
of the air bag I hook each loose end of the wires d d¹ to its respective block, for
example one end of the wire d is hooked to one side of the block b while the other
end of the same wire is hooked to the block b¹. The other wire d' is similarly
fastened to the other side of the same two blocks and the air bag is then inflated.
The pressure pulls the wires up tight so that they cannot possibly escape from the
blocks. By deflating the air bag the wires are sufficiently slackened to permit of
their being unhooked from the blocks so as to allow of the removal of the cover e.
When so deflated the cover can be thrust to one side so as to allow the wires to be
got at.
The object of placing the anchor blocks b b¹ within the rim instead of
simply perforating the rim as might suggest itself, is that by using these inner blocks
no holes are made in the rim and water is prevented from getting into the rim. Of
course instead of anchor blocks such as I have described I might braze or secure
eyes or lugs to the inner side of the rim a, the sole object being to secure an inner
boldfast or anchorage for the wires d d¹.

page_text: The wires might be headed instead of being hooked or might be otherwise
formed in any manner calculated to create a secure holdfast to the anchor block,
eye snug or other part secured to or formed on the rim.
In the case of the hollow rim g shown at Fig. 7 no objection to perforating
the inner thickness of the rim exists and I may therefore form holes h in the said
inner thickness and hook the wires d d' into these holes. I might however use the
anchor blocks or their equivalents in the hollow rim also.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
(1) As means for securing the confining and embracing wires of the covers of
pneumatic tyres to trough shaped "solid," hollow or sectional rims of velocipede or
other wheels, the anchor blocks or their equivalents secured to or formed on
the inner side of such rims in combination with the hooked, headed or otherwise
suitably formed loose ends of the embracing wires d d for the purposes and
substantially as herein before described and shown.
(2) As means for securing the wires of pneumatic tyre covers to hollow rims of
the type shown at Fig. 7, perforating the inner thickness of the said rims so
as to receive the hooked loose ends of the wires d d substantially as described
and shown.
(3) The general arrangement, construction and combination of parts comprising
my improved means for securing the covers of pneumatic tyres to the rims of
wheels, substantially as described and as illustrated.
Dated this 26th day of March 1895.
