PROVISIONAL SPECIFICATION.
A New Adjustable Chain and Chain Wheel Cover and Lubricator
for Cycles.
I JOSEPH GEORGE GROSE of 39 Ambush Street Saint James End in the
County of Northampton Cycle Agent do hereby declare the nature of this inven-
tion to be as follows:-
In carrying out my invention I provide a light frame made of steel, iron or other
like material of proper size and shape, over which I fit leather or other like sub-
stance which is fastened by means of lacing on the under side, by which means it
can be fastened and unfastened almost instantly..
To the top of the frame I attach an ordinary lubricator, through which flows a
constant supply of oil, for the purpose of keeping the chain and chain wheels con-
stantly oiled.
This covered frame I properly fit over the chain and chain wheels of a cycle
which prevents the depositing of dirt or dust within the chain and chain wheels,
and it also prevents the dress from getting into the chains.
The advantages of my invention are
1. It can be manufactured at a very small cost and can be attached to and
detached from the cycle almost immediately.
2. The chain and chain wheels are protected from dust and dirt which prevents
to a great extent the wearing of the same.
3. It is a dress guard.
4. It is provided with a means of constant lubrication of the chain and chain
wheels which greatly adds to the ease of the rider.

COMPLETE SPECIFICATION.
A New Adjustable Chain and Chain Wheel Cover and Lubricator
for Cycles.
I, JOSEPH GEORGE GROSE of 39 Ambush Street, Saint James' End in County
of Northampton Cycle Agent 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:-
In carrying out my invention, I provide a light frame preferably concave in
section made of steel, iron or other like material the proper size and shape, over
which I fit leather or other like substance thus forming a case or cover the mouth
or opening of which is at the bottom when fixed in position the mouth is closed
and securely fastened by means of lacing across.
To the top of the frame I attach an ordinary lubricator through which flows a
constant supply of oil for the purpose of keeping the chain and the chain wheels
constantly oiled, and to effect this object more readily I pass a small wick through
the lubricator, one end of which touches the chain so that when travelling each
link of the chain gets effectually oiled, at the same time prevents the oil in the
lubricator from running too freely.
This covered frame I properly fit over the chain and chain wheels of a cycle and
secure thereto by means of two or more cross stays or bars, the ends of which are
riveted or bolted in the top and bottom of the steel frame and clip the framework
of the cycle, thus securely keeping the case or cover in position. I form the back
TD 077

page_text: end of the aforesaid steel frame loose and bolt it to the other part, thus enabling
the backwheel of a bicycle to be taken out without the trouble of taking off the
whole of the steel frame, and in the aforesaid loose end I form a slot at top and
bottom so as to enable the steel framework to be elongated if required.
The cover itself as heretofore mentioned is made of leather or other like
substance, sometimes I form it of one piece, cut the required shape and size so that
when it is doubled over, and sewn at the two ends it forms a cover or case to,
enclose the before mentioned frame, and in other cases I form it of two pieces, when
it is sewn together at the top as well as the two ends. When fitting my chain and
chain wheel cover to a machine, I first fix in position the metal frame as shewn in
Fig. 3 by means of the cross bars or stays bb I then proceed to put on the cover
itself which is held mouth downward and drawn over the frame, a hole being cut
in one side of the cover to receive the crank axle of the machine, and one in the
other side to receive the back wheel axle, and from each of these two holes a slit
is cut to the bottom of the cover, to enable the same to be drawn down, when it
should fit the frame tight all round; the two edges of the mouth or opening
butting together, and by means of laces and hooks or other similar fastenings I
fasten together the two edges of the mouth and also the two slits thus forming it
dust proof.
Fig. 1 of the drawing annexed hereto shews the cover when made complete
and fitted with the wick lubricator. A heretofore described 9 shews one of the
holes cut in sides of cover to receive axles.
Fig. 2 shews the framework without the cover, c being the concave frame here-
tofore referred to, a representing the wick lubricator and bb the cross stays or
bars which are made in two parts, so as to clip the framework of the machine, and
then secured together as shewn in drawing.
'
Fig. 4 is a section of same through e f the parts lettered being the same as in
Fig. 2.
Fig. 3 represents the framework of the cover fitted to the framework of the
machine the parts lettered a, b, c being the same as in Fig. 2 & 4, d is the part of
the framework of the machine to which the cover is attached.
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
1st. An adjustable cover or case that can be manufactured at a very small cost
and which can be attached to and detached from the cycle in a few minutes with
.the ordinary tools carried by most cyclists.
2nd. Great lightness.
3rd. Constant lubrication of the chain and the chain wheels by means of the
lubricator fixed on the top of the steel framework.
4th. The chain and chain wheels being protected from dust or dirt, thus pre-
*venting the wearing out of the same to a great extent.
Dated this 1st day of October 1892.
JOSEPH GEORGE GROSE.
