Improvements in the Rims and Tires of Wheels, especially applicable
to Velocipedes.
1, ALEXANDER TIMOTHY BROWN, of 205 Shonnard Street, Syracuse, Onondaga
County, in the State of New York and United States of America, Manufacturer,
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:-
My invention relates to vehicle tires, and more particularly to those of bicycles
or velocipedes.
My object is to produce an clastic or cushion tire, which can be readily applied
to, or removed from the rim or felloe of the wheel and which is securely locked
upon
said rim, when in use, either with or without a pneumatic sack within it, the
edges of the tire being enlarged and fitting in concave seats in the lateral edges of
the rim, and being held therein by a band which encircles the rim and normally
partially, or nearly closes the seats in the rim, thus enclosing the enlarged edges of
the tire.
My invention consists in the several novel features of construction and operation
hereinafter described and which are specifically set forth in the claims hereunto
annexed.
It is constructed as follows, reference being had to the accompanying drawings,
in which
Fig. 1, is a transverse section of the tire, pneumatic sack inflated within it, the
rim, and the locking band.
Fig. 2, is a like view of the same parts, not inflated, and showing the band
pushed to one side to permit one edge of the tire to be forced into its seat, and the
other edge out of its seat.
Fig. 3, is a like view of the same parts, showing the band pushed to the opposite
side from that shown in Fig. 2, and the other edge just seated, or ready to be
removed.
Fig. 4, is an elevation of part of a wheel, partly sectional.
A, is the wheel, provided with a rim or felloe a convex inwardly, provided with
edge concavities a and with a plane, or substantially plane, surface between said
concavities, which constitutes the outer faces of the rim.
B, is a band of metal fitting loosely around the rim, and somewhat wider than
the outer surface thereof, so that its edges overlap the inner edges of said
concavities a'.
C, is the tire, constructed of rubber, with a canvas or cloth lining, thickened
centrally and of substantially the concavo-convex form shown, and having its
lateral edges enlarged or thickened as at c', creating a neck c¹ adjacent to each
enlargement.
These enlargements are of the same form as the concavities a¹ in which they are
seated.
D, is a pneumatic tube, of any desired construction placed within the tire.
At regular intervals the inner face of the rim is perforated as at all.
At corresponding intervals the outer face of the rim is slotted transversely, said
being opposite or in line with the perforations a¹.
slots m
At like intervals and in like alignment with these perforations and slots, the
band B is provided with apertures b', so that when a bar n is inserted through a
perforation and slot and into one of said apertures, then, that portion of said
band adjacent thereto, can be pushed to one side or the other, as shown in
Figs. 2 & 3.

page_text: In Fig. 2 the band is shifted to the right, which opens part of the concave
seat a¹, on that side to receive the enlarged edge of the tire. Then passing clear
around shifting the band and inserting the edge of the tire, that whole edge is
inserted.
Then passing the band clear over to the left, as in Fig. 3, and moving around
from one perforation to another and shifting the band, the whole of the right edge
of the tire is inserted into its seat, a¹.
Then pushing the band back to the centre as in Fig. 1, both of its edges will
overlap the enlarged edges and fit substantially against the necks c¹¹ on each side.
Then, when the previously inserted pneumatic tube is inflated, it will lock the
band upon the tire, and the band will lock the edges of the tire, as shown in
Fig. 1.
It preferable to have the enlarged edges of the tire of a diameter somewhat
less than that of the seats a¹ therefor in the rim, requiring them to be forced over
into said seats, where they will then fit closer and more or less elastically.
To remove the tire, I empty the pneumatic sack, and reverse the operation of
putting it on.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1: In a vehicle wheel, a plano-convex rim, provided with edge concavities and
perforated and slotted as shown, in combination with a band fitting around said rim,
and perforated at intervals, and a tire having thickened edges, locked in the rim
concavities by said band, and a pneumatic sack inflated within said tire.
2: The combination with a vehicle tire, crescent-shape in cross-section and
having thickened side edges, of a plano-convex rim formed with concave side edges
for the reception of the thickened edges of the tire, and a band fitting around the
plane of the rim and adapted to be moved sidewise to lock both thickened edges in
their respective seats.
3: In a vehicle wheel, the combination with a rim formed with concave edges, of
a hollow tire having thickened edges adapted to be seated in said concave edges, a
pneumatic sack within the tire, and a band fitting around said rim and adapted to be
manipulated to lock said thickened edges in their respective seats and unlock the
same, through the medium holes in the rim.
4: A vehicle tire, crescent-shape in cross section and having thickened edges
adapted to be seated in the concave side edges of the rim, in combination with a
continuous band adapted to be shifted sidewise to lock or fasten said thickened
edges in their respective seats.
