PROVISIONAL SPECIFICATION.
Improvements in the Construction of Poles or Shafts for Road
Vehicles.
1, HENRY FORMAN, of Chellaston, Derby, in the County of Derby, Commercial
Traveller, do hereby declare the nature of this invention to be as follows:-
:-
The object of my invention is to provide a shaft or pole for carriages or other
vehicles which shall be lighter than those constructed of wood and at the same time
possess great strength and elasticity and reduce to a minimum the risk of breakage
or splintering in case of accident.
In carrying out my invention I form my pole or shaft of steel or other metal
and of suitable section preferably of two downward curves united at the top by an
upward or downward curve or curves or corrugation or corrugations the two
downward curves turning inwardly and then upwardly. I may if found desirable
make the metal thicker in the middle and tapered to the outer ends transversely so
as to ensure greater strength and lightness.
may braze or otherwise fix to the ends of the shaft or pole so formed
solid or other blocks or hinged devices so as to admit of their being attached to
the carriage, or vehicle in any well known manner and I may insert plugs or blocks
of wood or other material for the purpose of securing by screws rivets or the like
housings for various harness fastenings or suitable clips or straps may be provided
in place thereof so as to embrace the shaft or pole.

COMPLETE SPECIFICATION.
Improvements in the Construction of Poles or Shafts for Road
Vehicles.
1, HENRY FORMAN, of Chellaston, near Derby, in the County of Derby,
Commercial Traveller, 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 :—
The object of my invention is to provide a shaft or pole for carriages or other
vehicles which shall be lighter than those constructed of wood and at the same time
possess great elasticity and reduce to minimum the risk of breakage or splintering
in case of accident.
In carrying my invention into practice I form my shaft or pole of suitable metal
instead of wood in the following manner.
Referring to the accompanying sheet of drawings,
Figures 1, 2, 3 and 4 show in section various modifications of my metallic shaft
or pole.
Figure 5 is an elevation of a vehicle fitted with my metallic shafts.
I form my shaft or pole from sheet band or fat metal preferably steel by
drawing rolling or hammering or by partially rolling and afterwards bending or
turning up the outer edges of the sheets or rolled strips or in any other well
known manner, and of a skeleton curved or corrugated section the shafts or poles
not being tubular.
Figures 1234 in the accompanying sheet of drawings show sections which I
prefer to use but other similar modifications of sheet or flat metal of sections

page_text: consisting of a series of curves may be employed without departing from the
spirit of my invention. In order to increase the strength if desired a portion of
the metallic pole or shaft may be thickened out at say the crown, as shewn by the
dotted lines A in Figure 1 and the shafts or poles may be also strengthened
throughout in places such as points at which it is necessary to attach fittings by
inserting an inner short lining or duplication of the section employed as shewn by
dotted lines B in Figure 5 which may be brazed or otherwise.secured and through
which and the outer skin or plate rivets bolts &c. may taken to secure harness
fastenings and the like or blocks of wood or other material may be employed for
this purpose. The point or tip may be of solid metal or may be strengthened or
blocked as before described.
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
In road or like vehicles the use of a metallic shaft or pole of section such as
shown in Figures 1, 2, 3 and 4 of the accompanying sheet of drawings or of any
equivalent modification thereof substantially as herein described.
