Improvements in Chain-guards for Cycles.
I, HENRI VALLÉE, of 27 Rue d'Alger, Mans (Sarthe) in the Republic of
France, Engineer, do bereby declare the nature of this invention to be as
follows:-
My invention relates to the cases or guards ordinarily used to cover the endless
chains of bicycles and other cycles.
It consists of a box of metal, celluloid, or other suitable material, made in two
parts, the upper part being connected to the lower part by bolts.
The box is in the shape of a deep trough in cross section, of sufficient width to
embrace (without touching) the driving wheels round which the chain passes.
The part or end which surrounds the chain wheel on the driving wheel axle is
made separate from, and slides in, the other part or end which surrounds the chain
wheel on the pedal axle, so that the length of the guard may be adjusted to suit
the length of the chain.
The improved chain guard is fixed round the axle boss of the driving wheel at
one end, and round the bearing of the pedal axle at the other end by means of two
brackets and a bolt, by which it is attached.
The lower half of the improved chain guard may contain a sufficient quantity
of oil, into which the chain dips and is lubricated.
The guard is cut away to allow the bearing of the pedal axle to pass.
Improvements in Chain-guards for Cycles.
I, HENRI VALLÉE, of 27 Rue d'Alger, Mans (Sarthe) in the Republic of
France, Engineer, 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, and accompanying drawing, that is to say :-
My invention relates to the cases or guards ordinarily used to cover the endless
chains of bicycles and other cycles, and it has for its object not only to protect
the chain and toothed gear from dirt and dust, but also to allow the constant
lubrication of the chain in a bath of oil, so that the machine runs extremely
smoothly and evenly, whilst the cleaning of the chain and gear is greatly
facilitated.
The improved chain guard is illustrated in the accompanying drawing, in
which
Figure 1 is a side view and Figure 2 a transverse section of it, on the line x-x,
Figure 1.
Figure 3 is a front view of the fastening device.
It consists of a box of metal celluloid or other suitable material, made in two

page_text: parts A and B, the upper part being connected to the lower part by bolts C
and D.
The box is in the shape of a deep trough in cross section, of sufficient width to
embrace (without touching) the driving wheels round which the chain passes.
The part or end E which surrounds the chain wheel on the driving wheel axle
is made separate from, and slides in, the other part or end E¹ which surrounds the
chain wheel on the pedal axle, so that the length of the guard may be adjusted to
suit the length of the chain.
The improved chain guard is fixed round the axle boss of the driving wheel
at H at one end, and round the bearing of the pedal axle at the other end, or
upon the tubes of the frame, by means of two brackets and a bolt, as shewn at I.
Figures 1 and 2.
The lower half B of the improved chain guard may contain a sufficient quantity
of oil, as shewn at G, into which the chain dips as it travels and is kept constantly
lubricated.
The guard is cut away at K to allow the tubular frame to pass.
atman of my soid inven-
Having
HOW
inven
particularly described and ascertained the nature of my said
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The chain guard of metal, celluloid, or other material, in the shape of a box in a
two parts A and B, connected by bolts C and D, the part E sliding in the part E¹,
and the entire chain guard being fitted and fixed round the axle of the driving
wheel at H, and fitted round the pedal axle and bolted to the frame tubes at I,
the lower part of the box being arranged to hold a sufficient quantity of oil or
other lubricant, through which the chain passes, substantially as described and
shewn in the drawing.
