PROVISIONAL SPECIFICATION.
Improvements in Connecting Rods.
THOMAS EDGE Mechanical Draftsman 60 Ainsworth Lane, Bolton-le-Moors
JOHN ROBERT ROSCOE Mechanical Engineer 301 Laurel Cottage, Manchester
Road West, Little Hulton, near Bolton do hereby declare the nature of this
invention to be as follows:-
Our improvements, relate to connecting rods, & consist in an arrangement,
that permits of greater facility of setting & dispenses with the extreme accuracy
of erecting machinery, that at present exists.
In order that a connecting rod end on a crank pin shall work in the same plane
as the connecting rod end at the cross-head it is necessary that the longitudinal
centre lines of the pins, should be parallel, this condition necessitates great care
in obtaining & the slightest variation from it, results in trouble & general
inconvenience.
Our improvements, allow each end of a connecting rod to move in the same
plane, or each in a different plane.
No. 1 arrangement consists in making the bushes or steps at each end of a
connecting rod with a parallel hole & the backs of the bushes spherical & making
the connecting rod ends to fit them or :-
No. 2 arrangement, making the bushes or steps at both ends of the connecting
rod with spherical holes to work on spherical pins in crank & cross-head the backs
of the bushes in this case can be made spherical or any other construction or the
bushes can be dispensed with & the spherical pins work in spherical holes at the
connecting rod ends.
No. 3 arrangement. Nos. 1 & 2 arrangements may be combined & used in the
same connecting rod one arrangement at each end of the rod.
No. 4 arrangement. The connecting rod to have spherical ends, working in
spherical bearings.
No. 5 arrangement. One end of the connecting rod to have a spherical end to
work in a spherical bearing & the other end with bushes spherical at the back &
a parallel hole or the bushes may have a spherical hole to work on a spherical
pin, the back of the bushes in this case being spherical or of any construction or
the bushes may be dispensed with & the connecting rod end have a spherical hole
to work on a spherical pin.
This invention is not only applicable to connecting rods of steam or other motor
engines, but is intended to be applied to all cases where connecting or coupling
rods, links, bars, distance pieces, or by whatever term they may be called are
required to have their end connections to work in the same plane, or in a different
plane, as mentioned at the beginning of the description.

THOMAS EDGE Draughtsman 60, Ainsworth Lane, Bolton-le-Moors, JOHN
ROBERT ROSCOE Mechanical Engineer 301 Manchester Road West, Little
Hulton, near Bolton-le-Moors 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:-
Our improvements relate to connecting rods & consist in an arrangement that
permits of greater facility of setting & dispenses with the extreme accuracy of
erecting machinery that at present exists.
In order that a connecting rod end ou a crank pin, shall work in the same plane,
as the connecting rod end at the cross-head, it is necessary that the longitudinal
centre lines of the pins should be parallel this condition necessitates great care
in obtaining & the slightest variation from it results in trouble & general
inconvenience.
Our improvements allow each end of a connecting rod to move in the same plane
or each in a different plane.
No. 1 arrangement consists in making the bushes or steps marked Bat each
end of a connecting rod, with a parallel hole & the backs of the bushes, spherical
& making the connecting rod ends marked R to fit them.
No. 2 arrangement. Both ends of a connecting rod, to have the bushes marked. B
made with spherical holes to work on spherical pins in crank & cross-head, the
backs of the bushes in this case can be made spherical or any other construction,
or the bushes can be dispensed with & the spherical pins work in spherical holes at
the connecting rod ends (marked R).
No. 3 arrangement. The Nos. 1 & 2 arrangements may be combined & used in
the same connecting rod, one arrangement at each end of the rod.
No. 4 arrangement. The connecting rod to have spherical ends marked E working
in spherical bearings.
No. 5 arrangement. One end of the connecting rod to have a spherical end
marked E to work in a spherical bearing & the other end with bushes marked B
spherical at the back & a parallel hole or the bushes marked B may have a
spherical hole to work on a spherical pin, the back of the bushes in this case
being spherical or of any construction, or the bushes may be dispensed with &
the connecting rod end have a spherical hole to work on a spherical pin.
This invention is not only applicable to connecting rods of steam or other
motor engines, but is intended to be applied to all cases, where connecting or
coupling rods links, bars, distauce pieces, or by whatever term they may be called,
are required to have their end connections to work in the same plane or in a
different plaue, as mentioned at the beginning of the description.
Having now particularly described & ascertained the nature of our said inven-
tion & in what manner the same is to be performed we declare that what we
claim is :-
Spherical end connectious for connecting rods so that the ends of the rods may
work in the same or different planes.
