Improvements in or applicable to Pedo-motive and Manu-motive
Apparatus.
I, FREDERICK WILLIAM ZIMER, of Coleman Street, in the County of London,
Gentleman, do hereby declare the nature of the said invention to be as follows:-
This invention is applicable to pedo-motive and manu-motive apparatus, and
consists (as applicable to pedo-motive apparatus) in so constructing, adapting,
and mounting the pedal levers on their shaft as that they may receive at will
either a continuous rotary motion or a reciprocating motion, in either case
imparting motion to their shaft during the downward thrust of the foot.
According to an advantageous modification of carrying such invention into effect,
each pedal lever is mounted loosely upon the shaft and is fitted with a ratchet
wheel which is keyed on the shaft and is operated by a spring pawl carried by the
pedal. The inner side of the pedal lever is recessed with one or more through
holes and the ratchet is also pierced with opposite holes arranged in a circular
manner equidistant apart. Between the pedal lever and its standard or support is
a grooved clutch which is mounted loosely on the shaft and by suitable means can
at will be caused to abut either against the standard or against the pedal lever.
The clutch is provided with a key or keys which at all times engages or engage
with the recess or recesses in the pedal lever, and, when the clutch is moved so as
to abut against the pedal lever, also engages or engage with one or more of the
recesses in the ratchet wheel. In the latter case, the pedal is intended to be con-
tinuously rotated by the foot, but in the former case it is intended to be depressed
by the foot and automatically raised into position for each next depression. To
effect the automatic return of the pedal-lever, the clutch is provided with a projection
so shaped as, when the clutch is moved into abutment with the standard, to partly
surround a quadrant-bar which projects from and is supported by the standard and
is encircled by a spring one end of which, at such time, abuts against the projection
so as to be compressed thereby at each depression of the pedal, and so as, when
relieved from the pressure of the foot, to return the pedal-lever as aforesaid, the
quadrant-bar being also adapted with a spring catch which prevents the return of
the pedal lever beyond a predetermined position, and when the pedal-lever is being
continuously rotated forms a bearing for the adjacent end of the spring, and when
the clutch is moved from the pedal-lever towards the standard, permits of the
projection passing into engagement with the spring. The clutch is moved into
either of the positions above mentioned, by means of a surrounding clutch ring
formed with a projecting pin which engages with an inclined slot formed in the
standard and is kept by a spring in constant engagement with only the pedal-lever,
(or also with the ratchet wheel,) from which normal position it can be moved by
the operator as required by any suitable connection leading from any convenient
position for actuation by the operator.
The invention also consists in so constructing, adapting and mounting the pedal
levers on their shaft as that they may receive a reciprocating motion at all times, as
distinguished from a continuous rotary motion as ordinarily, the downward move-
ment being imparted by the foot and the return movement being automatically
effected. In such event, according, for example, to a modification of the arrange-
ment hereinbefore described, each pedal lever adapted with the ratchet wheel and
spring pawl as described would be connected directly to the spring the other end

page_text: of which would be connected to the aforesaid quadrant bar the clutch and its
actuating parts in such an arrangement not being required.

COMPLETE SPECIFICATION.
Improvements in or applicable to Pedo-motive and Manu-motive
Apparatus.
I, FREDERICK WILLIAM ZIMER, of Coleman Street, in the County of London,
Gentleman, do hereby declare the nature of the said 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 has especial reference to pedo-motive apparatus, and consists in
so constructing, adapting and mounting pedal-levers on the shaft they are intended
to actuate, as that they may be caused to receive, at will;-either a reciprocating
motion effected by the feet operating alternately, the depression of each pedal
raising the other into operative position; or an independent reciprocating motion
effected by the feet operating alternately, or together, if required, their return
motion being effected by independent springs ;-or a continuous rotary motion
which may be effected by the feet operating alternately, or together, if desired ;-
in each case imparting motion to the said shaft during the downward thrust of the
foot or feet.
The improved apparatus is represented on the accompanying drawings, in side
elevation in Fig. 1, and in front elevation in Fig. 2. Fig. 3, represents a sectional
elevation through the pedal-casing in the plane (of the direction of motion)
indicated by the line a-, Fig. 4. And Figs. 4 and 5, represent sectional elevations
thereof on a plane (at right angles to the direction of motion) indicated by the
line cd, Fig. 3, looking respectively in the directions of the arrows e, f.
6, represents a pair of pedal-levers, which are loosely mounted on the shaft 7,
they are intended to actuate; the shaft being supported in a framing 8, which may
form part of the cycle or other apparatus to which the apparatus is applied. Each
pedal-lever, at the part adjacent to the shaft, is constructed or fitted with a recessed
half-casing 9, to which is bolted as at 10, a like half-casing 11. Within each casing
thus formed, there is a ratchet-wheel 12, which is keyed on the shaft ;-a pawl 13,
which is formed with a toe-piece 14, and is carried by a pin 15, supported by the
casing, and is normally kept out of engagement with the ratchet-wheel by a
spring 16-a pin 17, which projects through and can turn freely in both sides of
the casing, and has keyed thereon a socket 18, formed with bearings 19, supporting
a pawl 20, which is controlled in its outward movement by a spring 21, and stop 22,
(the pin 17, being adapted externally of the casing, as hereinafter described);-a
pin 23, which is supported by the casing and is formed with a projecting toe-
piece 24, adapted to engage with the pawl 20, and is provided with stopping pins 32,
and is fitted with a spring 25, tending (when operated in the manner hereinafter
described) to throw the pawl 13, into engagement with the ratchet-wheel; -and a
screw 26, by which the pawl 13, can, if required, be kept in constant engagement
with the ratchet-wheel.
Each pin 17, has keyed on its ends, externally of the casing, a link 27, to the
other end of which is connected a bifurcated bar 28, the pair of such bars being
respectively detachably connected to the arms (m, n,) of a common lever 29, which,
also, is supported by the framing 8.
30, represents attachments, also supported by the framing 8, serving as convenient
means of attaching springs 31, the other ends of which, when required to be used,
are connected to the ends of the links 27, to which the-bars 28, are connected, when
such bars and the lever 29, are disconnected therefrom as hereinafter described.

page_text: When the pedal-levers are desired to be used. as connected reciprocating pedals,.
so that the depression of each pedal will raise the other pedal into operative position;
the screw 26, is set back so as to prevent it from engaging with the pawl 13, the
springs 31, are disconnected from the links 27, which latter are respectively con--
nected to the arms m, n, of the lever 29; by the bars 28. Then (vide Fig. 1.) when
either pedal (say, for example, the rider's left pedal g,) is depressed from the position
it is represented as occupying, (its casing (9, 11,) turning in the direction of the
arrow i, vide Fig. 3,) it, by the connections. 17, 27, 28, 29, 28, 27, 17, described,
simultaneously raises the pedal h, into the position from which it (9,) started, the
arm m, of the lever 29, travelling to the position of the arm n, and such latter arm
simultaneously travelling to the position. o, indicated in dotted lines. The same
motion of the pedal g, in consequence of the keyed connections of its link 27, with
its pin 17, causes such pin to turn in its bearings in the casing in the direction
of the arrow j, (vide Fig. 3,) in consequence of which, the pawl 20, acting against
the toe-piece 24, turns the pin 23, in the direction of the arrow k, which causes the
spring 25, to turn the pawl 13, in the direction of the arrow 1, into engagement.
with the ratchet-wheel 12, in consequence of which the motion of the pedal g, is
communicated to the shaft 7.
When the pedal-levers are desired to be used as independent reciprocating pedals,
so that the return of each is independently effected, then the bars 28, are disconnected
from the links 27, and the latter are connected to the standards 30, by the
springs 31, each of which automatically raises its attached pedal-lever upon its
being relieved of the pressure of the foot bearing thereon.
When the pedal-levers are desired to be used as continuously rotating pedals,
both the bars 28, and springs 31, are disconnected from the links 27, which are
linked to the relatively adjacent bolts 10, and the pawls 13, are kept in constant
engagement with the ratchet wheels 12, by the screws 26.
The hereinbefore described clutch mechanism may, with equal advantage, be
applied to manu-motive apparatus.
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 :-
