PROVISIONAL SPECIFICATION.
Improvements in Tyres and Rims (or Felloes) for the Wheels of
Cycles, Bath Chairs, Carriages, and other Vehicles.
I, ROBERT HARDING RAINS residing at Moss Bank, Matlock Bridge in the
County of Derby, Surgeon, do hereby declare the nature of this invention to be as
follows:-
The tyres are of various forms. The accompanying drawings show fourteen
sections A to N but many more varieties may be made. Several of the tyres are
of crescentic form and overlap the rim at their edges.
Tyre A consists of an inner tube T¹ composed of canvas and rubber with an
outer crescentic tyre fitting upon it.
In sections B, C, F and H no inner tube is shown but each has a slightly
different rim.
All the rims shown except that in section J are either the same as or slight
modifications of those made by Messrs. Warwick of Birmingham.
In sections E, K, and N the rims are entirely enclosed by the tyres.
In all the remaining sections the tyres have a centrally situated air containing
cavity, either round, oval, or ovoid, and lips or margins of various form which
overlap and fit into corresponding depressions upon the edges of the rims.
All the tyres are made of india-rubber and canvas or other suitable material,
galvanised or not, and they are provided with a tube having a valve or stop-cock
for the purpose of inflation.
Section F shows a piece of canvas, U, cemented to the rim and margins of the
tyre to further secure same.
R = rim.

COMPLETE SPECIFICATION.
Improvements in Tyres and Rims (or Felloes) for the Wheels of
Cycles, Bath Chairs, Carriages, and other Vehicles.
I, ROBERT HARDING RAINS of Moss Bank, Matlock Bridge, Derbyshire,
England, Surgeon, 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 :-
The sides of the rim are turned up and rolled over so as to form a groove into
which the lips of the tyre (A. A.) are made to fit These lips may be (1st) either
cemented to the rim or
(2nd) retained in place by means of two narrow strips (hoops) of metal
(B. B., Fig. 2) placed one upon each side of the spokes (so as to compress the
aforesaid lips) and connected together at frequent intervals by hooks or screws or
in such other manner as to be held secure.
(3rd) or the lips of the tyre may be firmly held by a piece of wire (C.C., Fig. 3)
forced down between the spokes and the edge of the rim as shown in Fig. 3.

page_text: The tyre may be solid or hollow and may vary in size and shape, it may also
have a canvas insertion, (shown by the dotted lines in Figs. 3 and 4).
Several modifications are shown in Figs. 1 to 4.
In the inflated forms the inflation is made through the rim.
All the figures on the annexed sheet are sections of the tyres and rims.

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. Great case in removing the tyre so as to change or effect repairs.
2. That repairs to the tyre may be made from the inside and are thus much
more effectual as the subsequent inflation presses the material used firmly upon the
rent.
3. That wide or narrow tyres may be used upon the same rim.
4. Greater portion of the tyre available for lateral displacement and such
displacement is not impeded by the margins of the rim.
Dated this Ninth day of October 1891.
