PROVISIONAL SPECIFICATION.
Improvements in connection with Cycle and other Road Vehicle
Tyres, and Attachments thereto.
1, GEORGE LAMB, of No. 81 Sommerville Drive, Mount Florida, in the County
and the City of Glasgow, Scotland, Commercial Traveller, do hereby declare the
nature of this invention to be as follows:-
My invention relates to cycle and other road vehicle tyres and attachments
thereto; and, has for its object the rendering of these vehicles more efficient by
reducing or removing their liability to slip or slide when in use.
My said invention consists of a simple and convenient series of cavities or
indentations on the periphery of wheels, said indentations or cavities being placed
at more or less equal distances on the outer surface of the tyre or its attachment,
and which are, by preference, of a conical or diamond-shaped form, or any other
style or shape of indentation that may give efficiency to the object of my
invention.

Improvements in connection with Cycle and other Road Vehicle
Tyres, and Attachments thereto.
I, GEORGE LAMB of No. 81, Sommerville Drive, Mount Florida, in the City
and County of Glasgow, Scotland, Commercial Traveller, 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 :-
27
This invention relates to cycle and other road vehicle tyres generally, but
relates more especially to an improved cover or band for pneumatic tyres and
has for its object reducing or obviating the liability of tyres to slip or slide
when in use, especially on wet or greasy roads. It consists essentially in
forming a series of cavities or depressions of any suitable shape and size on the
trend portion of the tyre or tyre cover; or on a separate band capable of being
fixed to a tyre cover so as to form the tread thereof."
I will now more particularly describe my invention making reference to the
accompanying drawing in which :-
Figure 1 is a view in plan of the trend of a pueumatic tyre, showing by way of
example one form my invention may assume, and Figure 2 is a view in longitudinal
section thereof on line - of Figure 1.
Throughout both views similar parts are marked with like letters of reference.
The head portion A of the pneumatic tyre is provided with cavities or
depressions a formed in any suitable manner. The depressions may be of a conical,
circular, square, polygonal or any other shape, but the shape I prefer to use is a
diamond shape as illustrated. The tyre cover may be moulded and vulcanized
with the said cavities or depressions in the usual manner and backed with cauvas
1

page_text: or the like either before or after vulenuization as usual, or the cavities or
depressions might be produced by stamping or cutting them out of a band of
sheet rubber and then backing this perforated band with another sheet of rubber
or canvas or rubber and canvas combined and then vulcanizing them or fixing
them by nicans of rubber solution to each other. In the case of non-slipping
bands to be applied to existing pneumatic tyres the band might well be constructel
as above described, that is, by punching, stamping or perforating a rubber band
with any desired pattern and fixing to the tread of the tyre cover by means of
rubber solution or in any other way,
I am quite well aware that prior to this invention non-slipping bands or covers
for tyres have been made with various devices; for instance, corrugations, raised
fancy patterns or devices, but all these various devices have been found wanting
and have not been altogether satisfactory in preventing slipping, and have besides
been very dirty in use
In practice it is found that the cavities or depressions a a do not become filled
or clogged with mud or dirt, thus producing a very clean tyre, even in muddy or
dirty weather.
It will be understood that this invention is applicable to all types of tyres
for cycles or vehicles, either pneumatic tyres or otherwise.
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 1
claim is :-
(1) A non-slipping tyre for cycle and other vehicle wheels having a series of
cavities or depressions on the tread thereof, as and for the purpose set forth.
(2) A non-slipping cover or band for pneumatic tyres provided with a series of
cavities or depressions, as and for the purpose set forth.
(3) A non-slipping cover or band for pneumatic tyres constructed substantially
as herein before described and shown.
Dated this 14th day of July 1890.
