Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the steering gear of bicycles, in which a cross bar or
handle is used to move the fork carrying the steering wheel.
The improved apparatus consists of a short horizontal screw, having a sufficient
number of threads and gearing with a corresponding tangent wheel which is

or semicircular frame turning upon a vertical axis or centre on the frame of
the bicycle, and having attached to it a transverse bar provided with handles.

Improvements in Steering Gear for Bicycles.
I, PIERRE JOUGUET, of 36, Rue du Chateau, Paris, 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 :-
This invention relates to the steering gear of bicycles, in which a cross bar or
handle is used to move the fork carrying the steering wheel.
The accompanying diawing is in illustration of my invention, Figure 1.
representing a plan of the improved steering gear applied to a bicycle, and.
Figure 2 a side view of the same looked at from the left hand.
The improved apparatus consists of a short horizontal screw a, having a sufficient.
number of threads (three being shown in the drawing) and gearing with a
corresponding tangent wheel or pinion b which is fixed upon the upper end of the.
wheel fork c.
The endless screw a turns in bearings d¹ carried by the frame d of the bicycle,.
and outside the inner bearing is fixed upon the projecting axis of the screw a
toothed pinion g which gears with corresponding teeth upon a horizontal segmental
bar or semicircular frame i turning upon a vertical axis or centre p on the frame.

or balls l, m, at its ends.
The toothed segment i is formed upon a semicircular frame h formed upon or
attached to the steering bar j, which turns upon the centre p, and is held by a nut n.
The semicircle is marked with a scale and figures, by which the amount of angle
through which the steering wheel is turned can be determined, a fixed band or
pointer upon the support d¹ pointing out the indications.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The guiding bar pivotting upon the frame and actuating by means of a toothed and
graduated sector, and a pinion gearing with it, an endless screw driving a
corresponding tangent toothed pinion formed or fixed upon the fork of the steering
wheel, substantially as described and illustrated.
