page_text: I WALTER TAYLOR, of Norman Park, Brisbane, in the Colony of Queensland,
do hereby declare the nature of this invention to be as follows:
My invention relates to bicycle driving gear so arranged that the hands as well
as the feet of the rider can be employed for propulsion.
For this purpose I mount under the steering handles a sprocket wheel which is
connected by a chain to a sprocket pinion on the pedal axle, this axle having on
it also the usual sprocket wheel connected by a chain to the sprocket pinion on
the boss of the driving wheel. I pivot the steering handles in the head of the
steering spindle so that they can be moved up and down, the boss which holds
them being thus caused to rock. This boss is connected by two cords or chains
passing over guide pulleys to two segments pivotted on the axle of the sprocket
wheel first mentioned, and having pawls which engage ratchet teeth at the sides
of the wheel. As the steering handles are moved up and down each of the
segments are caused to reciprocate each in turn being moved in the direction,
and retracted by a spring, thus giving a step by step movement to the sprocket
wheel, this being communicated to the pedal axle.
In order to prevent the one movement interfering with the other the chain
connecting the hand driven wheel with the pedal pinion, the chain may be made
50 as to act as a ratchet slipping one way. In order to provide a suitable bearing
for the axle of the hand driven wheel, I make the frame with a diagonal stay
connecting the top of the saddle tube to the lower end of the bearing for the
steering spindle, and a diagonal stay connecting the bearing for the pedal axle
to the top of the bearing for the steering spindle, these two stays crossing each other
se as to form a bearing for the axle of the hand driven wheel.

page_text: to be performed, to be particularly described and ascertained in and by the
following statement:-
My object is to provide a detachable hand-driving gear for cycles, in order
that the latter may be moved at a greater speed than is now possible.
In order to accomplish my object, I use, in combination with the handle-bar
and the ordinary driving gear situated between the crank axle as now used, and
the rear wheel of cycle, an additional gear.
This hand-driving gear can be fitted on any kind of cycle, but certain parts f
the frame of the latter must have divided members, to facilitate the working of
the endless chain, sprocket wheels, quadrants, &c.
To illustrate what I mean by divided members, and to show the position of my
gear on cycles, I have, in the accompanying drawings, selected the frame of a
gentleman's bicycle.
This additional driving gear is made detachable, it being possible to remove
it in a few minutes. The movable handle-bar can be substituted by an ordinary
handle-bar, which at once renders the machine, almost in every particular, like
an ordinary cycle.
In order that my invention may be better understood, I shall now refer to the
accompanying drawings, on which similar letters of reference indicate similar
parts in all the views.
Figure 1 is a side elovation of a cycle with my additional driving gear.
Figure 2 is a prospective view of the cycle frame shown in Figure 1.
Figure 3 is a vertical section of the two quadrants, the upper sprocket wheel,
with ratchet wheels combined, showing axle bearings of same, and detachable
parts of cycle frame.
Figure 4 is a side elevation of one quadrant.
Figure 5 is a side elevation of upper sprocket wheel, before ratchet wheels are
secured thereto.
Figure 6 is a side elovation of one of two ratchet wheels, which are screwed one
on either side of upper sprocket wheel.
Figure 7 is a transverse section of the bottom bracket of cycle frame, showing
crank axle, cranks, and two sprocket wheels.
Figure 8 is a side elevation of the fork, cam, and wheels of the handle-bar
combination, showing how the steel cords work on same.
Figure 9 is a transverse section of the handle-bur combination, showing cam
and wheels.
The cycle frame which I have selected, in order to show the position of my gear,
is comprised of The rear wheel fork (A), having the two axle bearings (B and B);
the two bottom divided members (and C); crank axle bearings (1) and 1));
the two divided vertically inclined supports ( and E); the two detachable
members (F and F), with axle bearings (G and G) secured both top and bottom
by suitable bolts; (I 1) is the seat pillar, situated between the upper end of the
rear wheel fork and the bottom bracket of cycle frame (D) and D): (L) is the
front fork, with axle bearings for front wheel; (K) is the head of cycle frame,
and shows the position of the handle-bar combination.
(1) is a movable cycle handle bar, which moves on suitable bearings attached
to fork (J), the lower end of which is secured to the upper end of front wheel
fork (T). The handle-bar, moving freely on the aforesaid bearings, .can be
operated to the extent of about 13 inches radius. It carries a cam (M), below
which are situated two small wheels (N and N) carried by a pin (0) secured' to
fork (J). Said wheels are free to act upon the said pin (0), and serve to
guide two steel cords (Q and Q), whilst the cam (M) draws them upon it, or
releases them therefrom. Said steel cords are guided one over and on to said
cum (M) and the other under and upon the latter, and are secured at their ends
to the quadrants (R and R 1) and also to the cam (M). (P) is a small pulley to
prevent steel cords from brushing against the top bar (H) of cycle frame. (B2) is
a steel cord which passes round the pulley (1 1) and fastens at each end to the

page_text: quadrants (R and R 1). This steel cord is for the purpose of bringing back the
quadrants after they have done their work respectively. While one quadrant is
being drawn up the other is being drawn down, by reason of this steel cord (B2).
(S) is the axle of the aforesaid sprocket (T), and (U and U1) are the before
mentioned ratchet wheels secured by suitable screws to each side of the said
sprocket wheel. The said two quadrants (I and R 1) are one upon each side of
said sprocket wheel (T), and move freely upon said axle (S). Said quadrants (R
and R1) oscillate on cone bearings, while sprocket wheel (T) revolves on
balls (and V) situated upon suitable cones, which are screwed upon screw-
threaded axle (S), and partly answer the purpose of the cone bearing for the
quadrants (R and R 1). (W and W) form the other parts of cone bearings for
the aforesaid quadrants, while (Z and 2) are nuts for adjusting same. (Y and Y)
are two adjustments for the purpose of adjusting chain (E 1). (A1 and A 1) are
nuts which serve the purpose of securing the axle (S) to the detachable parts of
cycle frame (and F). (A4 and A4) are the two pawls, carried by pins (A3
and A 3) secured by nuts (B1 and B31) to said quadrants. (H) is the top bar of
cycle frame. (G3) is the bolt which secured the two detachable members (F
and F) to the aforesaid top bar (H).
(C2) is the lower sprocket wheel secured to the centre of screw-threaded crauk
axle (C3) by lock-nut (2); (D1 and D 1) are balls which run on hardened steel
cups (D2 and D2), which are driven tightly into the bottom bracket of cyclo
frame; (T1 and T1) ore cones forming bearings for balls (D1 and D1);
(T2 and T2) are cranks; (G4) is the sprocket wheel which forms the connection
with rear wheel of cycle.
(1) is an endless chain, communicating motion between said sprocket
wheels (T) and (C2); (H2) is an endless chain, which communicates motion
between rear wheel and crank axle (C3).
power.
To illustrate the operation of my additional gear, we will suppose that I am
Bitting upon the machine and propelling same by means of the cranks. In the
meantime the handle-bar and quadrants are at a standstill, while the upper
sprocket wheel (T), and the endless chain (E1), are revolving by reason of crank
I wish to assist in propelling the machine with my hands, so I at once
proceed to lift the movable hanl-bar, which draws the quadrant (R) up, by
means of steel cord' (Q) fastened therrto: at the same time the pawls (A4
and 4) shoulder themselves against the ratchet wheel, aud thus assist in turn-
ing the upper sprocket wheel, at the same time putting tension on chain (E1),
which must of necessity assist me in turning the lower sprocket wheels (C2)
and (G4) faster, and thus communicate greater velocity to the rear wheel of
eyele. When I press the handle-bar down to its former position, I do so with the
same result as hereinbefore described. The other quadrant (R 1) is drawn up,
causing the pawls (A4 and A4) attached thereto to operate like they did on
quadrant (R). While this quadrant (RI) is oscillating forwardly, it brings
quadrant (R) back to its former position by reason of the endless steel cord (B2).
The handle-bar can be operated in any radius of from one to thirteen inches,
and, whether pressed down or lifted up, power is communicated therefrom to the
crank-axle, and thence to rear-wheel of cycle.
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
The combination and arrangement of the movable handle-bar (T), cam (M),
forked stem (J), steel cords (Q and Q), quadrants (R. and R 1), the endless steel
cord (12), pawls (A4 and A4), ratchet wheels (and 11), top sprocket
wheel (T), axle (S) with cones, endless chain (E1), sprocket wheel (C2), and
the crank-axle ((3) of the ordinary driving gear, situated between snid crank-
axle (3) and the rear wheel of cycles, as hereinbefore described and as illustrated
in my drawings.

page_text: Secondly A detachable hand-driving gear for all kinds of cycles, in addition
to the ordinary driving gear. This hand-driving gear to be situated in the body
of cycle frame, and in a direct line from handle-bar to crank axle of cycle, as
heroinbefore described and as illustrated.
