PROVISIONAL SPECIFICATION.
Improvements relating to Velocipedes.
We JOSEPH VAN HOOYDONK of 762 Holloway Road, London, N., Engineer,
and FREDERICK NOCKOLD of 63 Hatton Garden in the City of London, Diamond
Cutter, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to a covering for the driving gear of bicycles and tricycles,
and the invention consists in a novel mode of producing such covering.
In the manufacture of velocipedes, the great desideratum is that all the parts
should combine lightness with strength, and it is therefore evident that a covering
for the driving gear, which is rather desirable than necessary, should add but little
to the weight to be carried.
In carrying out this invention, we may employ a light frame of tin or other
suitable material, and we form the panels or sides of fine wire gauze coated with a
suitable enamel, or it may be of thin papier maché or other light material. Or we
may mould the gauze or other material to the desired form, and secure it to the
frame of the velocipede in any convenient manner.
We make the trunk or main portion in one piece, leaving the ends removable, so
that in case of necessity the gear wheels may be readily got at.
The axles of the gear wheels will project through the covering, which will be of
a width sufficient to enclose only the chain and wheels or other gear.
Dated this 31st day of March 1892.

COMPLETE SPECIFICATION.
Improvements relating to Velocipedes.
We JOSEPH VAN HOOYDONK of 762 Holloway Road, London, N., Engineer,
and FREDERICK NOCKOLD of 63 Hatton Garden, in the City of London, Diamond
Cutter, 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 a covering for the driving gear of bicycles and tricycles,
and the invention consists in a novel mode of producing such covering.
In the manufacture of velocipedes, the great desideratum is that all the parts
should combine lightness with strength, and it is therefore evident that a covering
for the driving gear, which is rather desirable than necessary, should add but little
to the weight to be carried.

suitable material, and we form the panels or sides of fine wire gauze coated with a

suitable enamel, or it may be of thin papier maché or other light material.
may mould the gauze or other material to the desired form, and secure it to the
frame of the velocipede in any convenient manner.
In the accompanying drawings we have shown several plans for carrying our
invention into effect.
In the arrangement shown at Figs. 1 and 2, Sheet I, A is a frame of light metal,
which is formed with a ring A' at the pedal end, and a straight back end. This
frame may consist of flat strips of a width slightly in excess of the width of the
gearing, or of curved or channel shaped pieces, the straight end being formed by
two bars.

page_text: The sides B of this frame are formed of wire gauze, which may be coated with
enamel or light material, or may be formed entirely of papier maché or other
suitable material.
The ring A' is intended to receive a disc cover A2 of metal or other material,
which encloses the pedal chain wheel, and is secured by a bayonet joint, or in any
other convenient manner which will admit of its being readily removed to get at
the gear.
The back end of the covering consists of a cap A³, which is secured to the body
by screws or otherwise (see the section Fig. 2).
Fig. 3, Sheet II, shows a slight modification of the above arrangement, the chains
working in separate channels formed of wire gauze or in telescopic tubes of metal or
other material, as shown at Fig. 4. In the latter case, the ends are formed in
halves longitudinally secured together in any convenient manner.
In both forms, Figs. 3 and 4, the stay C of the frame will pass through the space
between the channels, and does not interfere with the sides of the covering, as in
Fig. 1.
In Figs. 5 and 6 we have shown a papier maché moulded covering in side view
and cross section.
The covering is formed in halves, spaces being provided for the gear axles and
the stay C, and the two parts are secured together by loops or eyes, and pins, or a
wire.
The upper half is supported from the frame by means of the luga or ears D.
Two steadying discs E E' may be provided on the bottom bracket, between which
one edge of the case is inserted, so that the case is thereby held firmly in position,
and lateral motion is prevented.
Figs. 7 and 8 show in side elevation and section a clip arrangement for securing
the two parts of the covering or case together. The said clip arrangement consists
of a return flanged piece on each edge of the parts of the cover, on to which (when
two pieces are brought together) a metal clip is slidden.
Fig. 9 shows a moulded wire gauze case coated with celluloid or other suitable
material, the parts being secured together by means of a clip arrangement of the
form last described, or in any other convenient manner.
Fig. 10 shows a moulded case formed in four pieces, that is to say, with the body
in halves, and with two caps or end pieces, the parts being secured together by a
clip arrangement, as above described, or in any other convenient manner.
Fig. 11 shows another mode of securing the parts of the body to the frame. On
the stay C are secured lugs or projections a a, carrying short pieces of tube b b,
which will correspond with loops or eyes on the parts of the cover (when in place)
to receive a wire, which passes through the tubes and the loops or eyes.
It is obvious that the body of the case may be made in one piece, with removable
caps or ends, and the case may be secured to the frame, and the parts of the case
secured together, in many ways other than those specified, which serve only as
examples.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1st. A case or covering for the chain gear of velocipedes, consisting of a light
metal frame with sides or channels of wire gauze coated with enamel, celluloid,
papier maché, or other light material, or of papier maché or other light material
alone, as and for the purpose set forth.
2nd. The combination with a case or covering of the description referred to in
Claim 1, for the chain gear of velocipedes, of a ring A' and a removable disc
cover A' at the pedal chain wheel end, as and for the purpose set forth.
3rd. A case or covering for the chain gear of velocipedes, consisting of moulded
wire gauze coated with enamel, celluloid, or other light material, or of moulded
papier mache, in two or more parts, as and for the purpose set forth.

page_text: 4th. In combination with a case or covering as claimed in Claims 1 and 3, of the
means substantially as herein shown and described with reference to Figs. 7 and 8.
of the drawings, for securing together the parts of the case or covering.
5th. In combination with a case or covering as claimed in Claims 1 and 3 of the
arrangement, as herein shown and described with reference to Fig. 11, for securing
the parts of the case or covering together, and to the frame of the machine.
6th. The combination with a case or covering as referred to in Claims 1 and 3,
of lugs or projections as shown and described with reference to Figs. 5, 7, 9 and 10,.
by means of which the case or covering is secured to the frame of the machine.
Dated this 31st day of December 1892.
