PROVISIONAL SPECIFICATION.
An Improved Rim, and Tyre therefor, to be applied to the Wheels of
Bicycles and other Vehicles.
I, ALBERT HALLOWELL, of Poplar Cottage, Lower Newlands, Brighouse, in the
Parish of Halifax, in the County of York, Silk Cardmaker, do hereby declare the
nature of this invention to be as follows:-
To consist of two rims with flanges, the flanges of the lower rim to come inside
the upper rim & to be held together by pins at regular distances, the pins are
fastened to the lower rim by means of their having a screw thread on & being
screwed slightly through & then riveted on the outside, the pins are not fastened
to the upper rim but a screw thread is put on the pins & they are fastened on the
outside of the upper rim by means of locknuts thereby allowing the upper rim to
buffer with the lower, between the two rims are indiarubber buffers through which
the pins pass, the buffer being of a very pliable nature allows for easy, working
of same & prevents jumping or jolting thereby ensuring smoothness of running.
A tube of hard wood or soft metal is put round the pins & through the buffer
extending from the inside edge of the lower rim to the outside edge of the upper
rim & is held fast by the lock nuts thereby preventing noise & friction in the buffer-
ing. The outside rim is made as follows, the flanges & centre are separate pieces
of metal, to the centre piece is fastened a solid rubber tyre, the tyre being flat on
the inner surface & having flats on either side of the outer surface the centre being
left half moon in shape, the rubber tyre is fastened to the rim by the flanges being
put on the flats of the rubber tyre & the whole being riveted through on to the
central portion the rubber of the tyre being hard in substance it will not be liable
to cut & yet will run noiselessly.

I, ALBERT HALLOWELL, of Poplar Cottage, Lower Newlands, Brighouse, in the
Parish of Halifax, in the County of York, Silk Cardmaker, 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:-
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation partly in section of my improved rim and tyre therefor,
applicable to the wheels of bicycles and other vehicles,

page_text: Fig. 2 is a sectional end view of Fig. 1.
Fig. 3 is a plan of cover opened out.
My improvement consists of an inner rim A, and outer rim B, the inner rim A
is preferably constructed flat, with flanges on each side, the rim B has also a flat
bearing surface, and in place of the flanges being at right angles as shown in rim A,
they are turned over on to the outer surface of the ordinary solid indiarubber tyre C,
for the purpose of clipping and retaining the same in position when fixed upon
the rim B. I also preferably construct the outer rim B in sections, and connect the
same with the inner rim A, by means of L shaped brackets D, which are rivetted
or otherwise attached to such rim A; a screwed pin, stud or bolt E attached to the
rim B, passes through the arm of the ☐ shaped brackets, and is secured by means
of nut and lock nut G.
Within the rim A I place a series of suitable buffers H, of natural, vulcanized,
or carbonized indiarubber, cut or blocked any suitable shape, and having a suitable
hole H through the centre; the outer rim B is supported by these buffers the ends
of which rest upon the said buffers, but not in contact with each other, so that when
pressure is put upon the buffer, or upon any particular section or sections, they do
not rub against each other, but allow each section to work independently.
The shaped brackets D also assist in retaining the buffers in a fixed position,
but for more effectually doing this, I employ suitable metallic clips F upon each
side, these clips are attached or rivetted to the sections of outer rim B; suitable
prongs or clips J formed upon these clips, are for securing the edges of a suitable
cover K, which may be employed for protecting the buffers and other working parts
from injury by damp, dirt or other causes.
By tightening or slackening the nuts G upon the screwed pin or stud E, the
elasticity of the buffer is regulated as desired. I also preferably place a washer L
of felt, indiarubber or other suitable material above the nut under the arm of the
bracket D on the screwed pin or stud, so as to prevent any noise in buffering.
By these means I obtain a tyre for the wheels of bicycles and other vehicles
which does away with puncture, runs noiselessly, and has all the elasticity and
resiliency of the pneumatic tyre.
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. Constructing rims and tyres of wheels for bicycles and other vehicles, of an
inner rim A and outer rim B, between which are fixed a series of indiarubber
buffers H, in the manner and for the purposes substantially as set forth.
2. In rims and tyres of wheels for bicycles and other vehicles, the combination
of an inner rim A and outer rim B, with a series of indiarubber buffers H, secured
together and held in position by brackets D), clips F, screwed pin or stud E, and
nuts G, with or without cover K, for the purposes substantially as set forth.
3. In rims and tyres of wheels for bicycles and other vehicles, the use and employ-
ment of an inner rim A, in combination with an outer rim B of suitable sections,
and connecting same by means of brackets D, screwed pin or stud E, and nuts G,
substantially as set forth.
