Improvements in and relating to Velocipedes.
W CHAPERS HENRY GUEST and LOUIS BARROW, trading as Guest and
Barrow, of Tower Works Torg
shire, Cycle Manufacturers do hereby declare the nature of this invention to be as
follows:-
Our invention relates to an improved method of constructing the frames of
velocipedes, and it has for its object, the reduction of the cost of production.
In carrying our invention into practice we take the requisite number of members--
which are preferably all straight and which may be either tubular or solid-and of
fittings, and we fix them together by bolts, rivets. or pins, and when the frame is so
put together, we galvanize the whole and thus firmly complete all the joints.
We find that this process of galvanizing makes a joint just as strong as brazing.
while it does not require such skilled labour, and does not perish the steel with heat
as in brazing.

COMPLETE SPECIFICATION.
Improvements in and relating to Velocipedes.
We CHARLES HENRY GUEST and LOUIS BARROW trading as Guest and
Barrow of Tower Works, Tower Road, Birmingham, in the County of Warwick-
shire, Cycle Manufacturers, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
illustrated in and by the following statement:-
Our invention relates to an improved method of constructing the frames of
velocipedes, and it has for its object the reduction of the cost of production.
In carrying our invention into practice. we take the requisite number of
members which are preferably all straight and which may be either tubular or
solid and of fittings, and we fix them together by bolts, rivets or pins, and when
the frame is so put together we galvanize the whole and thus firmly complete all
the joints.
We find that this process of galvanizing makes a joint just as strong as brazing
while it does not require such skilled labour and does not perish the steel with heat
as in brazing.
Hitherto the several parts constituting the frames of velocipedes have been fixed
together either by being bolted, screwed or rivetted together, or by being brazed
together, or by both the above means in combination. When the members of the frame
of a velocipede are merely bolted, screwed or rivetted together they are apt to
become loose and shaky from the excessive vibration to which they are subjected,
while frames which have members brazed together require a considerable amount of
"cleaning off" before they are fit to be painted or enamelled.
The object of our invention is to fit the several parts of the frame of a velocipede
together in a simple and cheap manner without in any way imparing its efficiency
or strength, and to this end our invention consists in fixing the several parts of the
frame together by screws, pegs or rivets and galvanizing the whole.
To carry out our invention we take the several parts forming the frame of n

page_text: velocipede and after fitting the same together, we screw, peg, or rivet them together.
We then galvanize them by dipping the whole frame in a bath of molten zinc, or
by first dipping it in a bath of molten zine, and afterwards in a bath of molten tin,
according to the galvano-tin process.

The molten zinc permeates all the joints and firmly fixes the several parts
together, and moreover coats them all with a smooth and even surface, leaving the
frame ready to be at once painted or enamelled, thus avoiding all cleaning off"
which adds so much to the cost of a frame the parts of which are brazed together.
A striking advantage of our method of construction is that it does not require
skilled labour and that the steel or other metal of which the members of the frame
are made is not liable to be damaged through being overheated as is the case with
brazing, while the coating given to the metal effectually protects it from the rusty
action of the atmosphere.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1st. The hereinbefore described method of constructing the frames of velocipedes
which consists in first screwing, pegging or rivetting the several parts or members
of a frame together, and then dipping the frame in molten zinc, or first in molten
zinc and then in molten tin, as set forth.
2nd. In the construction of the frames of velocipedes, the method of fixing the
several parts or members, by dipping the frame-after the said parts or members
have been screwed, pegged, or rivetted together-in a bath of molten zinc, as set
forth.
3rd. In the construction of the frame of a velocipede, the method of fixing the
several parts, or members together-after the said parts or members have been
screwed, pegged or rivetted together-by dipping the frame first in molten zinc and
afterwards in molten tin, as set forth.
