for Pneumatic Tyred Cycles.
I, CHARLES HENRY HORROCKS of 36 Cornbrook Park Road, Cornbrook,
Manchester, in the County of Lancaster, Medical Plaster Maker do hereby
declare the nature of this invention to be as follows:-
My invention consists in the application of the following ingredients used singly
or in combination with each other.
I take quantity of pulverized glass, or pulverized emery or iron filings or any
other ingredients of a gritty nature and intimately mix one or more of the
aforesaid ingredients with the outer rubber covering of a pneumatic tyre for
cycles, to prevent slipping or skidding on wet or muddy roads, when riding.

Improvements in Non-slipping and Non-puncturing Outer Covers
for Pneumatic Tyred Cycles.
I, CHARLES HENRY HORROCKS, of 36 Cornbrook Park Road, Cornbrook,
Manchester, in the County of Lancaster, Medical Plaster Maker, 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 :-
This invention relates to the composition of covers such as are employed to
encircle or enclose the air tube, or that may form a part of the air tube constituting
the pneumatic tyre for wheels of bicycles, tricycles, and the like.
The objects of this invention are to prevent side slip when running over greasy
stone sets or other places that are rendered slippery by the state of the weather or
from other causes, and to resist the usual causes of puncture.
In this invention I employ either pulverized emery, pulverized glass, pulverized
quartz, sand, iron filings, or any earthy, mineral, or other substance of a gritty
nature, which I mix in a greater or less quantity with india rubber, sulphur, and
oxide of zinc, the india rubber being previously dissolved in naphtha. The
aforesaid compound of india rubber dough or paste and gritty substance or
substances is intimately mixed and then worked in a rolling mill until thoroughly
incorporated. I then spread the mixture upon canvas or other suitable material,
or mould said compound into the form in which it is required to be applied either
as an outer cover for the air tube or in combination therewith, when it is vulcanized
in the ordinary manner.
In a modification of my invention I form strips of material composed of the
substances and in the manner as herein before described, that may be affixed to
existing covers or to air tubes by cementing thereto.
The aforesaid gritty substances may be powdered or dusted on the surface of the
india rubber dough or paste after it has been spread before vulcanizing.

page_text: Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I. declare that what
I claim is :-
==
1st. In covers that are employed to encircle or enclose the air tube, or that may
form a part of the air tube constituting a pneumatic tyre for the wheels of bicycles,
tricycles, and the like, the mixture or application of any mineral, earthy, or other
substance of a gritty nature with india rubber dough or paste used in the
manufacture of said covers in the manner and for the purpose substantially as
herein before described.
2nd. In combination with covers employed to enclose or encircle the air tube, or
that may form a part of the air tube constituting a pneumatic tyre for the wheels
of bicycles, tricycles, and the like, the use of strips of material composed of a
mixture of any mineral, earthy, or other substance of a gritty nature and india
rubber dough or paste spread on canvas or other fabric, that may be cemented or
otherwise affixed to existing covers, or to air tubes, substantially as herein before
described.
