I, EUSTACE ERNEST WIGZELL, of Billiter House, Billiter Street, London, E.C.,
Engineer, do hereby declare the nature of this invention to be as follows:-
In my improved method of construction I have two iron or steel plates cut T
or triangular shaped, I then lighten these pieces by cutting out the inner portion
as much as possible leaving a centre web. At the bottom point of these triangular
or T shaped pieces I place a bearing made of cast iron, or steel, or other suitable
metal, and on each side of this bearing I have one of my T or triangular shaped
plates riveted or bolted to same, the bearing being furnished with a cap and bolts
to make it adjustable on the crank pin. The other two points of the triangular
or T shaped pieces I thicken by riveting or welding on strengthening pieces to
receive pins to join the two plates together, which pins would be used for receiving
the connecting rods or links for connecting to other parts of the mechanism,
and on the centre between these two points, and directly over the bearing on the
crank pin, I have a cast iron, or steel, or other suitable metal bearing, or bearings,
which are riveted, or bolted, in between the iron or steel triangular or Ţ shaped
plates, with a top cap to receive the crosshead or pin from the guide blocks, making
it adjustable.
In between the parts of the sheets forming the arms of the Tor triangle I have
distance pieces riveted or bolted through as desired.
By this method of building connecting rods I can get great strength combined
with lightness, and for big powers this would be highly essential.

Connecting Rods for Steam Engines.
I, EUSTACE ERNEST WIGZELL, of Billiter House, Billiter Street, London, E.C.,
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:-
In my improved method of construction I have two iron or steel plates cut T

or T shaped pieces I place a bearing made of cast iron, or steel, or other suitable

plates riveted or bolted to same, the bearing being furnished with a cap and bolts
to make it adjustable on the crank pin. The other two points of the triangular
or T shaped pieces I thicken by riveting or welding on strengthening pieces to
receive pins to join the two plates together, which pins would be used for receiving
the connecting rods or links for connecting to other parts of the mechanism,
or should the connecting rod or rods be placed outside the T or triangular shaped
plates I can use a distance plug made of iron or steel or other suitable metal,
riveted or holted in position, with pins projecting outwards on each side to form
journals for bearings. In the centre, between the two outer points referred to
above and directly over the bearing on the crank pin, I have another cast iron, or
steel, or other suitable metal, bearing, or bearings, riveted or bolted in between
the iron or steel triangular or T shaped plates, with a top cap, to receive the cross-
head or pin from the guide blocks, making it adjustable.
The block forming the top bearing and the block forming the bottom bearing
can be made in one with a web or arm joining same together, this web or arm
coming in between the two outside plates, the top and bottom bearings could then
be finished before the plates were riveted or bolted on each side.
In between the parts of the sheets forming the arms of the T or triangle I have
distance pieces riveted or bolted through as desired.
By this method of building connecting rods I can get great strength combined
with lightness, and for big powers this is highly essential.
My improved connecting rod is specially adapted for use in the engine patented
to me under Letters Patent No. 22447 of 1894, and No. 26606 of 1896.
In the drawings annexed hereto Fig. 1 shows a front view and Fig. 2, an end
view of my improved connecting rod. Fig. 3, shows a section cut through the
two centre cast iron, steel, or other metal blocks and Fig. 4, one of the ends with
a cast iron, steel, or other metal block in between the two plates with two outer
journals.
In the drawings like parts are marked with like letters.
The outer wrought iron or steel triangular or Ț shaped plates are shown A with
holes for lightening same at B. B, leaving a centre web C. The bottom bearing
is shown at D, with the rivets or bolts which fasten the two triangular shaped
pieces A, to each side of the bearing D.
The two outer ends of the triangular shaped plates are shown at E, E, and in
Fig. 2, these ends are shown with strengthening pieces F riveted on for taking
the pins G joining the two plates together and for receiving the connecting rods.
Fig. 3 shows a section through the two middle bearings with the connecting piece,
or arm, joining the two together J, and furnished with distance pieces K."
Fig. 4, shows the block H, with pins I, I, projecting on each side for forming
journals.
The distance piece in between the two plates A, arranged in suitable positions
are marked L.
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. A built triangular or ↑ shaped connecting rod substantially as described
and shown in drawings.
2. In a built connecting rod the method of joining the two centre bearings, sub-
stantially as described and shown in drawings.
