PROVISIONAL SPECIFICATION.
Improvements in Shaft Couplings.
I, JOHN SMITH RAWORTH of 112 Belvedere Road, Lambeth, in the County of
Surrey, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in couplings between revolving shafts, and
is more particularly applicable to couplings between motive power engines and
dynamo electric machines. The said invention is designed more particularly to
allow each shaft to revolve freely in its own bearings without such bearings being
necessarily in an exactly straight line with the bearings of the other shaft.
In carrying my invention into effect I fix two studs or pins in the face of a
flywheel or the like secured on the driving shaft and two similar studs or pins in
the face of a wheel or the like on the shaft to which power is to be transmitted.
The two driving studs are connected with the driven studs respectively by a pair
of articulated or Hexible links each of which is secured to a driving stud at one
extremity and to a driven stud at its other extremity. These links are held apart
and are bent outward from one another by a strut or cross piece situated between
them so that the two articulated or flexible links form a figure closely resembling a
square with the strut crossing it diagonally.
The strut is supported entirely by the links to each of which one of its extremities
is secured, and does not take any bearing on the shafts.

COMPLETE SPECIFICATION.
Improvements in Shaft Couplings.
I, JOHN SMITH RAWORTH of 112 Belvedere Road, Lambeth, in the County
of Surrey, Engineer, 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 improvements in couplings between revolving shafts, and
is more particularly applicable to couplings between motive power engines and
dynamo electric machines. The invention is designed more particularly to allow
each shaft to revolve freely in its own bearings without such bearings being
necessarily in an exactly straight line with the bearings of the other shaft.
In the accompanying drawings,
Figs. 1 and 2 are sectional views at right angles to one another of a coupling
according to this invention.
1 and 2 are two studs or pins fixed in the face of a flywheel 3 or the like secured
on the driving shaft 4, and 5 and 6 are two similar studs or pins fixed in the face of
a wheel 7 or the like on the shaft 8 to which power is to be transmitted.
The two driving studs or pins 1 and 2 are connected with the driven studs 5 and 6
respectively by a pair of flexible links 9 and 10 each of which is secured to a
driving stud at one extremity and to a driven stud at its other extremity as shown.
These links are held apart and are bent outward from one another by a strut or
cross piece 11 situated between them, so that the two flexible links' form a figure
resembling a square with the strut crossing it diagonally.

page_text: The strut is supported entirely by the links to each of which one of its extremities
is secured, and does not take any bearing on the shafts.
Figs. 3 and 4 are similar views to Figs. 1 and 2 shewing a modification in which
each of the links 9 and 10 is made in two parts jointed together and to one end of
the strut or cross piece by a pin 12 the arrangement being otherwise similar to that
first described.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
Shaft couplings constructed substantially as shewn in and described with reference
to the accompanying drawings.
