Improvements in Manual Power Mechanism applicable to Cycles,
Boats, Carriages, and the like.
I, CHARLES SAMUEL BENSTED, of 156 Stanstead Road, Forest Hill, in the County
of Kent, Gentleman, do hereby declare the nature of this invention to be as as
follows:-
This invention for improvements in manual power mechanism applicable to
cycles, boats, carriages and the like has for its object to enable the driving effort
to be more effectively applied than is the case with manual power mechanism as
ordinarily constructed, and consists essentially in connecting driving cranks to
horizontal slides, or their equivalents, carrying pedals and working in suitable
guides by which means the thrust on the pedals is greatly increased over the
ordinary method where the pedals are directly under the rider and are therefore
operated by the weight of the rider only.
In one arrangement according to this invention as applied to a cycle there are
mounted on an ordinary cycle frame two cylindrical tubular guide casings in
which slide guide rods connected to cranks on or connected to the driving chain
wheel from which the driving wheel is driven by a chain and pinion in the usual
manner. In the said guide casings are slots through which arms carrying pedals
pass, and which are secured to the sliding guide rods. The guides are secured to
the frame by any suitable means and a seat having a back rest is provided.
When propelling a cycle constructed according to this invention the rider places
his back firmly against the back rest of the seat and his feet on the pedals, and, as
the back rest forms a surface of re-action or abutment preventing the body from
sliding, it will be evident that it enables the rider to transmit greatly increased
muscular force to the pedals.

I, CHARLES SAMUEL BENSTED, of 156 Stanstead Road, Forest Hill, in the County
of Kent, Gentleman, 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:-
-
This invention for improvements in manual power mechanism applicable to

page_text: cycles, boats, carriages and the like has for its object to enable the driving effort
to be more effectively applied than is the case with manual power mechanism as
ordinarily constructed, and consists essentially in connecting driving cranks to
horizontal slides or their equivalents, carrying pedals and working in suitable
guides by which means the thrust on the pedals is greatly increased over the
ordinary method where the pedals are directly under the rider and are therefore
operated by the weight of the rider only.
In the accompanying sheet of illustrative drawings:
Fig. 1 is an elevation in perspective of a tricycle constructed according to this
invention and Fig. 2 is a sectional plan of the propelling mechanism.
On an ordinary cycle frame are mounted two cylindrical tubular guide casings a
in which slide guide rods b connected by rods e to cranks on or connected to the
driving chain wheel e from which the driving wheel f is driven by a chain I and
pinion in the usual manner. In the guides a are slots through which arms
carrying pedals m pass, and which are secured to the sliding guide rods b.
guides are secured to the frame by means of clips no and bolts, as shown and a
seat having a back rest is provided.
The
When propelling a cycle constructed according to this invention the rider places
his back firmly against the back rest q and his feet on the pedals m and as the
rest forms a surface of reaction or abutment preventing the body from sliding,
it will be evident that it enables the rider to transmit greatly increased muscular
force to the pedals.
Although the invention is described as applied to cycles only it will be obvious
that with trifling modifications to suit altered circumstances, it is equally
applicable to boats, carriages and the like.
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. In manual power mechanism connecting the driving cranks to slides carry-
ing the pedals and working in horizontal guides, substantially as described.
2. In manual power mechanism the combination of the horizontal slots i guides
or casings a and pedals m substantially as described.
3. In manual power mechanism, the combination of the driving sprocket wheel e,
cranks d, connecting rods c, slots i, guides or casings a and pedals m, substantially
as described.
4. The improvements in manual power mechanism applicable to cycles, boats,
carriages and the like, the whole arranged and constructed substantially as
described and shown in the drawings.
