PROVISIONAL SPECIFICATION.
An Improved Method of and Means for Excluding Dust, Grit, and
the like from the Bearings of Velocipedes, Carriages, and other
Vehicles, applicable also to
to Bearings for Shafts, Axles, and
the like.
I COLLARD AUGUSTUS DRAKE of 17 Addison Road Kensington in the County of
London Gentleman do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a means whereby mud, dust, grit and
other deleterious substances may be excluded from the wheel pedal and other bearings
of velocipedes, the wheel or axle bearings of carriages auto cars and other vehicles
pedestals hangers and other bearings for machine and engine shafts and the like the
said means being easily applied to any existing bearing.
Now according to this invention I provide a disc or washer or cork, paper, woven
wire or other suitable material slit in any convenient manner to allow it to be passed
round the axle shaft or pin and to this disc or washer I attach by cement or other
suitable means a second disc or washer or pad of soft wool felt, wool, hair or any other
suitable soft material which will fit closely round the shaft axle or pin or against the
face of the rotating hub of the wheel so as to prevent dust grit and the like from
entering the bearing and yet offer no appreciable resistance to the rotation of the pedal
wheel crank axle shaft or other rotating piece of a vehicle or machine.
Or instead of the disc or washer herein before described I may use a ring of steel or
other suitable elastic material wound with cotton silk wool hair or other suitable
material to form a washer or grummet which be sprung over the shaft axle or pin.
The disc washers or grummets may be secured to the bearing or to the frame of the
machine by wire or other suitable means it being understood that it is my intention
wherever possible to secure the washers or grummets in such a manner that they
shall bear against the face of the bearing without rotating.
In cases where the washers or gummets are attached to any rotating piece of
mechanism for instance when applied to the wheels of bicycles I form the washers or
gummets in such a manner that they overlap the edges of the rotating piece and cover
the junction of the rotating piece with the fixed axle or pin so as to prevent dust or
grit from entering the bearing.
Instead of using washers or gummets I may use corrugated discs of metal and secure
pads of soft material in the corrugations.
Washers gummets and the like constructed as herein before described may be applied
to any rotating pieces of mechanism such as axles wheels and shafts with rotate on or
in bearings.

the like.
I COLLARD AUGUSTUS DRAKE of 17 Addison Road Kensington in the County of
London Gentleman 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 object of this invention is to provide a means whereby mud dust grit and
other deleterious substances may be excluded from the wheel pedal and other bearings
of velocipedes the wheel or axle bearings of carriages autocars and other vehicles
pedestals hangers and other bearings for machine and engine shafts and the like the
said means being easily applied to any existing bearing.
Now according to this invention I provide a disc or washer of cork paper woven
wire leather or other suitable material slit in any convenient manner to allow it to be
passed round the axle shaft or pin and to this disc or washer I attach by cement
or other suitable means a second disc washer or pad of soft wool felt, wool, hair
or any other suitable soft material which will fit closely round the shaft axle or pin or
against the face of the rotating hub of the wheel so as to prevent dust grit and the
like from entering the bearing and yet offer no appreciable resistance to the rotation
of the pedal wheel crank axle shaft or other rotating piece of a vehicle or machine.
Or instead of the disc or washer hereinbefore described I may use a ring of steel or
other suitable elastic material wound with cotton silk wool hair or other suitable
material to form a washer or grummet which may be sprung over the shaft axle
or pin.
The discs washers or grummets may be secured to the bearing or to the frame of the
machine by wire or other suitable means it being understood that it is my intention
wherever possible to secure the washers or grummets in such a manner that they shall
bear against the face of the bearing without rotating.
In cases where the washers or grummets are attached to any rotating piece of
mechanism for instance when applied to the wheels of bicycles I form the washers or
grummets in such a manner that they overlap the edges of the rotating piece and
cover the junction of the rotating piece with the fixed axle or pin so as to prevent
dust or grit from entering the hearing.
Instead of using washers or grummets I may use corrugated discs of metal and
secure pads of soft material in the corrugations.
Washers grummets and the like constructed as hereinbefore described may be
applied to any rotating pieces of mechanism such as axles wheels and shafts which
rotate in or on bearings and in order that my said invention may be fully understood
I will proceed to explain the same with reference to the accompanying sheet of
drawings in which
Fig. 1 represents cross section of a device for preventing dust and grit from entering
bearings constructed according to this invention.

Fig. 3 is end view of same.

Fig. 4 shows cross section of a nodified form of my invention.

page_text: Fig. 8 shews cross section of another modification.
Fig. 9 is side view of same.
Fig. 10 is end view of same.
The same letters denote the same parts in all the figs. a is a perforated disc of
metal, paper, cork or any other suitable material to which is attached by cement
or by any other suitable means a perforated disc washer or pad of felt, soft wool
hair or any other suitable soft material which will fit closely round the shaft axle
or pin and against the face of the bearing rotating wheel or other piece of mechanism
and so prevent dust and grit from entering the bearing.
The device shewn at Figs. 1. 2. and 3 is intended to be used for wheels rotating
on a fixed axis and the discs are flanged as shewn so that when in use the flange
projects over the hub of the wheel.
As shewn at Figs. 4. 5. 6. and 7 the device takes the form of a grummet having
a core of spring steel c or other suitable material on which is placed a covering of
chenille or other suitable inaterial.
In Figs. 8. 9. and 10 the device is shewn as a flat disc.
In all cases the rings or discs are slit as shewn at d to enable them to be passed
over the axles shafts or pins to which they are to be applied.
As will be seen on reference to the drawings the aperture in the pad b is somewhat
smaller than the aperture in the disc a so as to allow the pad to fit the axle shaft
or pin closely.
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.
CLAIMS.
1. The improved method of and means for excluding dust grit and the like from
bearings consisting in a washer pad or grummet of soft material closely surrounding
the axle shaft or pin and pressing against the bearing or rotating piece substantially
as hereinbefore specified.
2. A perforated slit disc or washer of metal cork or other suitable material a to
which is secured a disc washer or pad b of felt wool or other suitable soft material
substantially as hereinbefore specified and for the purpose stated.
3. In a device for excluding dust and grit from bearings the combination of an
elastic ring e with a covering of chenille or other suitable soft material substantially
as herein before specified and for the purpose stated.
4. Devices for excluding dust and grit from bearings coustructed as shewn by the-
accompanying drawings.
