Improvements in Wheel Rims for Vehicles.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of 18 Bucking-
ham Street, Strand, W.C., London, Patent Agent, do hereby declare the nature
of this invention a communication to me from abroad by S. N. Brown and Co.,
a body corporate, of Dayton, State of Ohio, United States of America, 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 improvements in vehicle rims more particularly to the
rims of sulkies, bicycles, etc.
Referring to the accompanying drawings which illustrate the invention,
Figures 1, 2, 3, 4, 5, and 6, are sectional views of the improved reinforcing or
strengthening band, applied to a wooden rim. The wooden rims shown in these
views are of varying thicknesses, and illustrate that the band may be applied to a
variety of wooden rims.
Referring in detail to the above views, the letter (a) designates a thin metallic
band constructed of metal that has a requisite amount of clasticity and hardness.
(b)designates wires which are completely inclosed in the outer circumferential edges of
said band, by being rolled therein. These wires, when so placed, form solid and
substantial beads that extend around the edges of said band, and are essential to
give said band the desired strength and elasticity, and to insure a durable quality
thereof. The joint formed by the meeting ends of the band, may be secured in
any suitable way, as by allowing the wires to project at one end beyond the end of
the band, and their insertion in the rolls of the other end of said baud, until the
ends of the wires meet, when said wires may be brazed and thereby made secure.
(c) designates a wooden rim or felley, which may be of any desirable form in cross
section, as is amply illustrated in the drawings; the outer circumferential surface
of said rim is concaved to receive the metallic reinforcing band, in which the
pneumatic tire is placed, and which tire it has not been deemed necessary to show
in the drawings. The band (a) may be shrunk on to the wooden rim, or it may
be placed thereon by compression, and when placed thereon, a stiffer or firmer
nature is imparted to the wooden rim, that greatly enhances its durability, and
enables said wooden rim to possess a minimum degree of weight and a maximum
degree of strength. When placed upon the rim the circumferential strengthening
beads formed by the wires (b) will inclose the outer edges of said wooden rim,
thereby preventing any chafing or splitting of said rim, and adding thereto, greater
power to resist lateral strain. Any pressure on the metallic band will naturally
have the effect of compressing or holding toward the center, the wooden rim, the
parts thereby becoming rigid and compact. There are a variety of ways of
applying the metallic reinforcing band to the wooden rim, but in each case it is
essential that the metallic band (a) be provided with the circumferential
strengthening beads, as this construction is a substantial means of preventing any
lateral or twisting movement of the rim.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, 1-declare that what
I claim is
1. The combination of a wooden rim or felly, of a metallic reinforcing band
around the outer periphery of said felly, wires rolled in the circumferential edges

page_text: of said metallic band, forming circumferential beads that inclose the outer edges
of said felly, substantially as and for the purposes specified.
.
2. In a wheel, the combination with the wooden rim, of a metallic reinforcing
band inclosing said rim, wires rolled in the circumferential edges of said metallic
band and projecting laterally beyond the edges of said rim, whereby means are
provided for protecting said rim against torsional strain, and for obtaining a specific
degree of lightness, substantially as described.
