PROVISIONAL SPECIFICATION.
Mud Guard or Tyre Cleaner for Cycles and all kinds of Vehicles.
I, LOUIS ARTHUR HIRST 6 Aviary Place off Canal Road Armley Leeds
Paper Ruler &c. do hereby declare the nature of this invention to be as
follows:-
Mud guard; to be used for throwing off anything, of an adhesive nature; cycle
& other vehicle wheels; may contract in there revolutions.
By means of a revolving brush, or brushes, or other material to answer same
purpose; not definitely fixed on.

LOUIS ARTHUR HIRST 6 Aviary Place, of Aviary Road Armley, Leeds Paper
Ruler. I 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 apparatus is so constructed that it may be applied to wheels of any
description. It consists of a spiral circular brush, made of rubber, or any suitable
material which is mounted on a spindle, & inserted in a swing frame, with the
periphery of the wheel to be cleaned at an angle to its axis which causes it to
revolve, & is kept in contact by means of a spring. F. 1 shows it as applied to a
cycle wheel.
A are the side rods adjustable in bracket B which is fixed to axle, of
cycle; at the other end is the swing frame C carrying brush D which is held in
contact with the tyre F by spring E. The brush is guarded by a small cover G
which deflects mud &c. to the ground.
Fig. 2 is an end view, showing spring frame C, & spiral brush D, pivoted by
pin M.
Fig. 3 is an end view of spiral brush, which are made preferably of india
rubber strips i, which are fixed on 3 sets of arms H which arms are fixed on a
spindle.
Fig. 4 is a front view of spiral brush & bearings; & method of lubricating:
JJ are bearings made of steel, or any other suitable material, K, K are the
lubricators at each end, for the supplying of grease or other lubricant. The
brush is formed in this way. We get a spindle of steel, on which is brazed 3 discs
with five arms to each. The rubber is then cut in strips & shaped to wheel; then
put between the arms, in a manner to form the spiral, the arms are then closed, to
make more secure, holes are drilled in the arms through which is put wire, going
through the rubber as well tying rubber to arms, the brush is now compleate. The
brush consists of 3 discs, spindle, wire & rubber strips. India rubber is the best
material known at present, owing to its elastic & yielding nature it grips the tyre
keener, cleans better, & partially dries the tyre; thereby making it much safer to
travel with; accidents by cycle tyres slipping; is reduced to a minimum; which
must be quiet patent to the observer.

page_text: BEARINGS.
Plain bush made of hard steel " long; the spindle ends projecting beyond the
bearings. This plan of bearings at present, pending more suitable.
LUBRICATING.
Brass caps are filled with grease, and forced on the end of bearings, thereby
forcing the lubricant into the bearings, causing the spindle which revolves at a
tremendous speed; to become lubricated, by its cappillary attraction.
We are reducing everything in weight, to bring in as cheap as ever possible.
The action of the veins of rubber, "or bristles" forming the brush, being spiral
and also set at an angle of 45 degrees say, with the axis of the wheel; is to
produce a side scraping action, whilst revolving at the same circumferential speed
of the wheel it may be attached too; and throwing all mud &c. it contracts, or
collects at a tangent to the ground.
Having now fully described, the nature and construction of my invention; I
declare my claim is
The combination of the spiral brush D mounted in swing frame C, and applied
to wheels by rod A. Constructed substantially in the manner shown and described.
And for the purpose set forth.
