PROVISIONAL SPECIFICATION.
Improved Means for Propelling Boats, Tricycles, and other Vehicles.
I, CHARLES LOCK, of 5, Peckham Terrace, Prestbury Road, Upton Park, in
the County of Essex, Pianoforte Maker, do hereby declare the nature of this inven-
tion to be as follows:-
My invention relates to boats, tricycles and other vehicles and to apparatus for
propelling the same by manual power.
In the Specification of former Letters Patent granted to me dated September 25
A.D. 1888, No. 13847 I have described mechanism for facilitating the propulsion of
velocipedes. The chief object of my present invention is the adaptation of such
mechanism for operation by manual power for the propulsion of what are known as
water velocipedes," tricycles and other vehicles.
$6
According to my present invention each crank has a spring arranged in
conjunction with it as heretofore, and in combination with the crank I arrange a
lever one end of which is adapted to be grasped by the hand while the other is
connected with a link which is also attached to the crank. When my improved
apparatus is used for a water velocipede the lever is advantageously arranged in
conjunction with a pulley and chain to enable the operator to sit face to bow. It
is obvious that I may employ two or more sets of cranks, levers and springs in
combination.
In some cases I dispense with the use of the levers, the chains or the like being
connected directly to the cranks.

COMPLETE SPECIFICATION.
Improved Means for Propelling Boats, Tricycles, and other Vehicles.
1, CHARLES LOCK, of 5, Peckham Terrace, Prestbury Road, Upton Park, in
the County of Essex, Pianoforte Maker, 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 :-
My invention relates to boats, tricycles and other vehicles and to apparatus for
propelling the same by manual power.
In the Specification of former Letters Patent granted to me dated September 25
A.D. 1888, No. 13847 I have described mechanism for facilitating the propulsion of
velocipedes. The chief object of my present invention is the adaptation of such
mechanism for operation by manual power, for the propulsion of what are known as
66 water velocipedes," tricycles and other vehicles.
According to my present invention the crank has a spring arranged in conjunction
with it, as described in the Specification before referred to, and in combination with
the crank I arrange a lever, one end of which is adapted to be grasped by the hand
while the other is connected with a link which is also attached to the crank. The
lever is advantageously arranged in conjunction with a pulley and chain.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawing which illustrates the application-of my
improvements to a tricycle.

page_text: Figure 1 being a plan; and,
Figure 2 an elevation.
a indicates the frame of the machine, b, b the driving wheels connected to the
axle c having the crank d, and e the steering wheel. ff and g, are the rods and
springs respectively arranged in conjunction with the crank d in the manner
described in the Specification of the Letters Patent before referred to. h is the
lever through the medium of which motion is communicated to the crank, which
lever is pivoted to the frame a at i, and j is the link serving to connect the lever /
with the crank as shewn in the drawing the lever is placed behind the rider's
seat and, in order that he may operate the same with his face towards the steering
wheel, I provide cords or chains k, k connected to the said lever and passing around
pulleys, on the front of the frame.
As shewn the lever h is bifurcated so that the cords k, k will pass one on each
side of the rider. m is a bar connected to the front ends of the cords k, k and
serving as a handle for enabling the rider to move the lever h. It is obvious that
the lever may be placed in front of the rider's seat, in which case the said lever is
grasped by the hand, the cords being unnecessary.
n, n are rests against which the rider places his feet in order to afford a good
purchase when working the machine.
The steering of the machine may be effected in any suitable manner as shewn
in the drawing I provide for steering by means of the feet, and for this purpose the
foot-rests n, n are pivoted at o, o and on the standard of the front steering wheel is
a lever p, having at its outer end a rod q against which the said foot-rests bear. It
is obvious that the rider, by pressing one foot-rest more than the other, corre-
spondingly acts on one end of the bar q and so causes the movement of the steering
wheel.
Although in the drawing I have only shewn a single crank it is obvious that I
may employ two or more sets of cranks, levers and springs in combination. In
some cases I dispense with the use of the lever and link and connect the chains or
cords directly to the cranks.
The arrangement hereinbefore described is especially applicable for use in
propelling small boats by means of paddle wheels as it enables the persons propelling
the boats to sit face to bow. In this case the paddle wheels are secured to the ends
of the shaft c mounted with the other parts of the mechanism in a suitable frame.
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. Improved means for propelling boats, tricycles and other vehicles, comprising
the combination of a cranked driving shaft, springs and rods in conjunction with the
cranks of the said shaft, and operating levers connected with the cranks by links,
substantially as described.
2. The improved means for propelling boats, tricycles and other vehicles,
comprising the combination of a cranked driving shaft; springs and rods in
conjunction with the cranks of the said shaft, operating levers connected at one end
to the cranks by means of links and having attached to the other ends cords or
chains passing around pulleys in front of the operator, substantially as described.
3. The combination with the boat, tricycle or other vehicle of means for propelling.
the same, substantially in the manner hereinbefore described and illustrated in the
accompanying drawing.
