IMPROVEMENTS IN TRICYCLES OR LIKE VELOCIPEDES
Year: 1884

page_text: I, AUGUST VON WEDELL of Klein's Hotel, No 38 Finsbury Square, E.C. in the
County of Middlesex, Gentleman, do hereby declare the nature of my Invention for
IMPROVEMENTS IN TRICYCLES OR LIKE VELOCIPEDES, to be as follows:-
My Improvement consists of an arrangement by which the handles are coupled
to the treadles and so the hands in connection with the feet may be used for driving
power in the manner as hereinafter described and illustrated in the accompanying
drawing.
To produce this coupling I fix, in place of the ordinary bearings on a tricycle
in which the handle bars are fixed, a cylindrical guide, as shown, "a" and
"a1 Fig 1" in the accompanying drawing, in which the handle bar “” slides in a
reciprocating motion. The handle bar directly below the handle is contracted; on
this contracted part of the saine is fitted a boss "c" carrying a pivot "d." On this
pivot "d" is fitted a bearing "e" which is attached to the upper end of the con-
necting rod "f" This connecting rod consists of two parts, viz:-a tube "g”
and a solid rod "f" the latter being fitted into the former and held therein by a set
screw "" to enable the adjustment of the connecting rod to convenient length.
The lower end of the tube "g" is fixed into a fork "h," which is fixed to the outer
treadle plate.
For the purpose of steering, the cylindrical guide "a" is provided with a notch
"k" in which is fitted a pinion in which tho handle bar "c" slides and is keyed
thereto by a tooth fitted into the bore of the pinion which tooth slides in a groove
cut in the handle bar. This pinion works in a rack which is connected to the
steering wheel in the ordinary way.
The handle may be disconnected from the treadle, if required, by slackening the
set screw "" in the connecting rod so as to allow the solid rod to slide in the
tube and the handles may be fastened to the frame by the set screw "m" in the
cylindrical guide.
The arrangement which connects the handle to the treadle may be attached to any
tricycle; in this case the bearings in which the handle bars are fixed are removed
and the cylindrical guide fixed to the frame instead and the fork at the lower end of
the connecting rod is fixed to the treadle plate.
If, when hill climbing, the bodily weight is not sufficient, a pair of braces, as
shown in Fig 2, which are laid round the shoulders of the rider, may be hooked to
the projections "n" at the sides of the saddle and thereby the rider is kept in the
saddle to gain additional power.

of the saddle to which the braces may be hooked, are arranged as shown in Fig 3
so that the rider may at any time leave the machine without being fastened thereto.

falls into a notch, as shown in Fig 3 p, and cross-Section Fig 3 A p.

page_text: I AUGUST VON WEDELL Klein's Hotel 38, Finsbury Square London in the county
of Middlesex, Gentleman, do hereby declare the nature of my invention for
IMPROVEMENTS IN TRICYCLES OR LIKE VELOCIPEDES, and in what manner tho
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
My improvement consists of an arrangement by which the handles are coupled to
the treadles and so the hands in connection with the feet may be used for driving
power in the manner as hereinafter described and illustrated in the drawing,
accompanying my provisional Specification.
To produce this coupling I fix in place of the ordinary bearings on a tricycle in
which the bandle bars are fixed, a cylindrical guide as shown "a" and "a 1 Fig 1" in
the accompanying drawing in which the handle bar "6" slides in a reciprocating
motion. The handle bar directly below the handle is contracted; on this contracted
part of the same is fitted a boss "c" carrying a pivot "d." On this pivot "d" is
fitted a bearing "e" which is attached to the upper end of the connecting rod "f."
This connecting rod consists of two parts viz:-a tube "g" and a solid rod "f" the
latter being fitted into the former and held therein by a set screw "L" to enable the
adjustment of the connecting rod to convenient length.
The lower end of the tube "g" is fixed into a fork "h" which is fixed to the outer
treadle plate.

For the purpose of steering the cylindrical guide a" is provided with a notch
"k" in which is fitted a pinion in which the handle bar "c" slides and is keyed
thereto by a tooth fitted into the bore of the pinion which tooth slides in a groove
cut in the handle bar. This pinion works in a rack which is connected to the steering
wheel in the ordinary way.
The handle may be disconnected from the treadle if required by slackening
the set screw "1" in the connecting rod so as to allow the solid rod to slide in
the tube and the handles may be fastened to the frame by the set screw
cylindrical guide.

The arrangement which connects the handle to the trendle may be attached to any
tricycle; in this case the bearings in which the handle bars are fixed are removed
and the cylindrical guide fixed to the frame instead and the fork at the lower end
of the connecting rod is fixed to the treadle plato.
If when hill climbing the bodily weight is not sufficient a pair of braces as shown
in Fig: 2 which are laid round the shoulders of the rider may be hooked to the
projections "n" at the sides of the saddle and thereby the rider is kept in the saddle
to gain additional power.
The hooks "o" which are fixed on the braces and the projections at the sides of
the saddle to which the braces may be hooked are arranged as shown in Fig 3 so
that the rider may at any time leave the machine without being fastened thereto.
The hooks are kept in their place whilst they are in use by a spring "p" which falls
into a notch as shown in Fig 3 p and cross section Fig: 3 A p.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is,
1. To obtain an additional driving power by coupling the handles to the treadles
substantially in the manner as heretofore described and illustrated in the
accompanying drawing.
2. The effecting of the steering in connection with the reciprocating motion of the
handle by which the additional driving power is applied substantially in
the manner as heretofore described and illustrated in the accompanying
drawings.
