Improvements in Crank Mechanism applicable to Engines, Cycles, and
other Machinery.
I, GIOVANNI ANTONIO PHILIPON, of Lima, Peru, South America, Watch Maker,
do hereby declare the nature of my said invention to be as follows:
My invention has for its object improvements in mechanism applicable to
engines, cycles, and other machinery by which considerable advantages are
obtained in transmitting say reciprocatory motion say into circular or revolving
motion as in the ordinary pedalling of cycles or lathes or in the reciprocatory
action of a piston in the cylinder of steam or other engines, my new mechanism
being connected to or in relation with the crank say of the fly wheel of an engine
or other revolving part.
In applying my invention to an engine whether driven by steam, electricity,
hydraulical or other power I pivot one end of a lever to the end of the piston
connecting rod. This lever is pivoted at the other end to the bed or any other
permanent part of the frame or bed. Mounted in suitable bearings fixed on the
bed is an axle or crank shaft on one end of which a pulley or fly wheel is
mounted. This axle or crank shaft is cranked near its centre or that part which
passes through a slot formed in the lever. In order to pass the crank shaft
through this slot I may form the part where the shaft is cranked in two parts
and connect them together by a crank pin by rivetting, shrinking or otherwise.
Or I may form the lever in two parts or make the slot wide enough to allow
the crank shaft to pass through.
It will thus be seen that when motion is imparted to the piston rod that the
connecting rod will reciprocate backwards and forwards thereby oscillating the
lever which imparts a circular or revolving motion to the axle or crank shaft
by which means motion is imparted to the driving pulley or fly wheel. In order
to reduce the friction in the slot in which the crank shaft works I mount a roller
or ball bearings on that part which works in the slot and I may also provide
the sides of the slot with renewable wearing surfaces. It will be evident that a
rotary motion may be converted into a reciprocatory motion. Although I have
described my improvements as applied to an ordinary engine it will be evident
that my invention may be applied in all cases where it is desired to convert a
reciprocatory or pendulum motion into a rotary or circular motion and vice versa.

I, GIOVANNI ANTONIO PHILIPON, of Lima, Peru, South America, Watch Maker,
do hereby declare the nature of my said 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 has for its object improvements in crank mechanism applicable to
engines cycles and other machinery by which considerable advantages are
obtained in transmitting say reciprocatory motion into circular or revolving
motion as in the ordinary pedalling of cycles or lathes or in the reciprocatory
action of a piston in the cylinder of steam or other engines, my new mechanism
being connected to or in relation with the crank say of the fly wheel of an engine
or other revolving part.
In applying my invention to an engine whether driven by steam electricity,
hydraulical or other power I pivot one end of a lever to the end of the piston
connecting rod. This lever is pivoted at the other end to the bed or any other
permanent part of the frame or bed. Mounted in suitable bearings fixed on the
bed is an axle or crank shaft on one end of which a pulley or fly wheel is
mounted. This axle or crank shaft is cranked near its centre or that part which
passes through a slot formed in the lever. In order to pass the crank shaft
through this slot I may form the part where the shaft is cranked in two parts
and connect them together by a crank pin by rivetting, shrinking or otherwise.
Or I may form the lever in two parts or make the slot wide enough to allow
the crank shaft to pass through.
It will thus be seen that when motion is imparted to the piston rod that the
connecting rod will reciprocate backwards and forwards thereby oscillating the
lever which imparts a circular or revolving motion to the axle or crank shaft
by which means motion is imparted to the driving pulley or fly wheel. In order
to reduce the friction in the slot in which the crank shaft works I mount a roller
or ball bearings on that part which works in the slot and I may also provide
the sides of the slot with renewable wearing surfaces. It will be evident that a
rotary motion may be converted into a reciprocatory motion. Although I have
described my improvements as applied to an ordinary engine it will be evident
that my invention may be applied in all cases where it is desired to convert a
reciprocatory or pendulum motion into a rotary or circular motion and vice versa.
In order that my invention may be clearly understood and more easily carried
into practical effect I have illustrated an example of my improvements as applied
to the cylinder of an ordinary engine which will be sufficient to enable others
to apply the same for various other purposes.
Figure 1 is an elevation of an engine cylinder with my improvements employed
thereto.
Figure 2 is a plan view of Figure 1.
Figure 3 is an enlarged view of the lever D.
Figure 4 is a cross sectional view of Figure 3 taken on the line a―y.
In applying my invention to an engine whether driven by steam, electricity,
hydraulical or other motive power I pivot one end of the lever D to the end
of the connecting rod B which is connected in the usual manner to the piston
rod A. This lever D is pivoted at the other end by the cross pin d to the bed E
or it may be pivoted to any other permanent part of the frame or bed. Mounted
in the bearings fixed on the bed E is the axle or crank shaft H on one end of
which the driving pulley or fly wheel P is fixed. This axle or crank shaft H

page_text: is cranked at and this cranked portion or its equivalent passes through the
slot or its equivalent formed near the supported or fixed end of the lever D.
In order to pass this crank shaft through the slot in the lever D I may
form the part or crank pin which connects the cranked parts or equivalents
together separate and connect it to these cranked parts by rivetting shrinking
bolting or otherwise. Or I may form the lever D in two parts or make the
slot sufficiently large so as to allow the crank shaft to pass through.
It will thus be seen that when motion is imparted to the piston rod that the
connecting rod will reciprocate backwards and forwards thereby oscillating the
lever ) and as this lever D oscillates it imparts a circular or revolving motion
to the axle or crank shaft H by which means motion is imparted to the driving
pulley or fly wheel P.
In order to reduce the friction in the slot to a minimum I mount a roller
or a ball bearing on the crank pin or part 2 of the axle or crank shaft which
passes through this slot and I may also provide the sides of this slot with the
renewable wearing surfaces which avoids the necessity of having to replace
the lever when the slot becomes worn and enlarged.
It will be evident that if it is desired to convert a rotary motion into a recipro-
catory motion say for instance that the wheel 1' had teeth upon its surface and
was in gear with another toothed wheel the rotation of this wheel P would cause
the lever D to oscillate and a reciprocatory motion would thus be obtained.
Although I have shewn my improvements as applied to an ordinary engine
it will be evident that my invention may be applied in all cases where it is
desired to convert a reciprocatory or pendulum motion into a rotary or circular
motion and vice versa.
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—
CLAIMS.
First: The improvements in mechanism applicable to engines cycles and
other machinery consisting of a lever such as 1) one end of which is pivoted to
any fixed or permanent part and having a slot or its equivalent such as which
engages with a crank shaft, crank pin or its equivalent for the purpose sub-
stantially as herein before described and as shewn upon the accompanying sheet
of drawings.
Second-The combination of a lever pivotedly fixed at one end with a crank
pin and in combination with a pedalling or reciprocating action whether manual
or mechanical for the purpose herein set forth and as shewn.
