Plain Axles.
I EBENEZER PARTRIDGE of Litho Villa, Poplar Avenue, Edgbaston, Birmingham
Warwickshire, Founder and Manufacturer do hereby declare the nature of my said
invention to be as follows :-
The object of this invention is to construct or make wings for axle flaps or clips
in a novel manner to suit their application to the flaps of ordinary plain solid welded
axles or to what are known as affixable solid flaps for plain axles.
For the purpose of my invention I make preferably by casting in malleable iron or
other metal a wing with a central recess, the end shoulders having a rib or fillet next
the recess above their level which ribs by a squeezing or hammering are forced down
upon a dummy or template to form a dovetail into which correspondingly shaped or
prepared edges of a plain flap of a solid welded flap axle or the plain shaped ends of
affixable solid flaps can be inserted to either of which my separately made wings are
attachable and capable of being permanently and solidly fixed, thereto when slid on
and by burring the end of the flap or by applying the wing whilst hot to affix itself
by shrinkage.
Instead of using the template or dummy the wing can be applied direct to a
prepared flap and the ribs or fillets can then by the squeezing or haminering operation
be put into contact for fixing one to the other."

The Manufacture of Butterfly Wings for the Flaps of Plain Solid
Welded Axles and for Affixable Solid Flaps or Clips Used with
Plain Axles.
I EBENEZER PARTRIDGE of Litho Villa, Poplar Avenue, Edgbaston, Birmingham,
Warwickshire, Founder and Manufacturer 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 :-
The object of this invention is to construct or make wings for axle flaps or clips in
a novel manner to suit their application to the flaps of ordinary plain solid welded
axles or to what are known as affixable solid flaps for plain axles.
For the purpose of my invention which I show in the annexed drawings I make
preferably by casting iron or other metal, malleable, a wing A Figure 1 with a
central recess B slighty tapered from a to b, as at Figure 2, the end shoulders C, C,
having a rib or fillet D next the recess above their level, which ribs by a squeezing or
hammering are forced in or down upon a dummy or template to form dovetail (as by
dotted lines) spaces correspondingly shaped to fit the prepared edges E. E of a plain
flap or clip F Figure 3, or of the Haps of a solid welded flap axle, or of the plain
shaped ends of affixable solid flaps to either of which my separately made wings
Figures 1 and 2, are attachable and capable of being permanently and solidly fixed
thereto as at Figure 4 when slid on and by burring the end of the flap F or by
applying the wing A whilst hot to affix itself by shrinkage.
Instead of using the template or dummy the wing A can be applied direct to a
prepared flap and the ribs or fillets D can then by the squeezing or hammering
operation be put into contact for fixing one to the other.
The base B of the butterfly wing A may have holes to reduce the weight of the
article as a casting.
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
1. The construction of butterfly wings as a separate article (preferably by casting.
and making malleable) from axle clips and in affixing them to axle clips by shrinking,
burring, hammering or otherwise, substantially as described with reference to
Figures 1 and 2 of the annexed drawings.
2. Shaping by dovetailing or otherwise the ends of axle clips for the affixture
thereto of butterfly wings as described and substantially as shown at Figures 3 and 4
of the annexed drawings.
