IMPROVEMENTS IN TRICYCLES FOR CHILDRENS USE
Year: 1885

page_text: I, ROUGHSEDGE WALLWORK Ironfounder, Union Bridge Iron Works Charter
Street, Manchester, in the County of Lancaster of the Firm of Henry Wallwork
& Company at the above address do hereby declare the nature of my invention
for IMPROVEMENTS IN TRICYCLES FOR CHILDRENS USE to be as follows:-
And consists firstly in the mechanical arrangement for securing the cranks, or,
pedal levers to the wheel, which in this case, is a front wheel to be driven, and two
wheels at the back to steady the same. In the first place I make the fork, back
stay holder, and handles all in one piece. In the bearings at the fork, where the
pedals work, I make the holes slightly conical largest upon there outer face-And
upon the crank I cast, a corresponding projection to fit into the fork, which forms
the bearing for to work in the fork, through this bearing I cast, or, drill a small
hole. Upon the inside face of this projection, or, bearing I cast small projections
say, one, two, or more but preferably, two, these two projections fit into corre-
sponding recesses, formed in the boss of the wheel, which has also, cast, or, drilled *
through, its boss a small, hole, of the same size, as is in the, pedal, or crank bearing.
By this means it will be seen, that by passing a small bolt, through the crank
bearings, and the wheel, I make them all firm, or, secure together, and capable of
being very easily taken to pieces and, put together again when necessary. Upon
the back stay I form the necessary arrangements for carrying the spring which can
be raised, or, lowered if necessary by a small wedge piece which is inserted between
the screw, and the spring and secured by the screw. I also upon the back stay
make the necessary arrangements for carrying the two wheels at the back.
The complete tricycle is so arranged in all its parts, so that it can easily be taken
to pieces, and put together again by any inexperienced person, for the purpose of
being sold if necessary as a large box toy, to be put together by the purchaser.

Street, Manchester, in the County of Lancaster of the Firm of Henry Wallwork
& Company at the above address do hereby declare the nature of my invention
for IMPROVEMENTS IN TRICYCLES FOR CHILDRENS USE and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
My improvement consists in the mode of securing the crank-or-pedal pieces of small
childrens the same is also applicable to large tricycles or bicycles. Referring to the
accompanying sheet of drawings, Fig. 1. shows a front elevation partly in section.
Fig. 2 shows a side elevation of the same. A. represents the boss of a tricycle or
bicycle wheel. B. represents the fork-or-bearing for treadle pieces-C. C. are
the treadle, or, crank pieces, upon these cranks I make one, two or more pro-
jections C 1-and upon the boss of the wheel I form corresponding recesses to
receive the projections upon the crank pieces or the projections may be upon the
boss of wheel but preferably upon the cranks, through the cranks and also through
the boss of the wheel I have a small hole through which I put the bolt D. and by
means of the nut, D 1. make the cranks secure to the boss of the wheel, and, all firm
together. Fig. 3 and 4. show another modification of my improvement in place of
the boss of wheel, this shows the treadle, or, crank pieces, secured to the chain
wheel of the tricycle E Fig. 3. being the bracket carrying chain wheel E 1.-
C. C. being crank pieces and C 1. the projections as described in Fig. 1 and 2.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I do declare that
what I claim is-
Firstly. The mode of securing the cranks or, pedal, pieces of bicycles and tricycles
by passing through the cranks, and, boss of wheel the bolt as shown.
Secondly. The arrangement of the projections upon the cranks, or, boss, and
securing the same by the bolt as shown and described in Figures 1. 2. 3. 4 of
Drawings.
