Improved Manufacture of Picks, Axes, Adzes, Hammers, and such
like Implements.
I, FREDERICK SIEMENS of 10 Queen Annes Gate Westminster in the County of
London, Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved manufacture of Picks, Axes, Adzes, Hammers,
and such like implements whereby the shank or handle and the head or tool are made
of a single piece of metal, thereby obviating the difficulty always experienced of
making an effective strong joint between the two. For this purpose I make use of
the known "Mannesmann
process, whereby metal tubes can be produced having
solid portions at one or more points of their length. Taking a length of such tubing
of steel having, for example a short solid length at one end and a longer solid length
at the other end, 1 form the latter length by forging and shaping, if necessary in
dies, into a tool head, such as that of an axe, adze, pick or hammer, while the
tubular part with its closed end is shaped in any desired manner for forming the
shaft or handle of the tool.
The tubular rods may be made of any convenient length with solid portions at
regular distances apart so that by cutting through such solid portions the rod can be
divided up into a corresponding number of blanks for the tools.
Dated this 12th day of June 1889.

solid portions at one or more points of their length. Taking a length of such tubing
of steel having, for example a short solid length at one end and a longer solid length
at the other end, I form the latter length by forging and shaping if necessary in dies,
into a tool head such as that of an axe, adze, pick or hammer while the tubular part
with its closed end is shaped in any desired manner for forming the shaft or handle

The tubular rods may be made of any convenient length with solid portions at

divided up into a corresponding number of blanks for the tools.
Fig. 1 of the accompanying drawing shews a bar formed with alternate tubular
parts S and solid part K, such as may be produced by the Mannesmann process
above referred to, the parts S being of such external diameter as to be conveniently
grasped by the hand. If this bar be cut through at the points, each section will
consist of a tubular part S constituting the handle which may be suitably shaped or
bent if required and a solid part K which can be converted into any desired form of
head or blade by forging or stamping in dies, such as a hammer as at Fig. 2, a pick
Prine fd1

page_text: as at Fig. 3, an adze as at Fig. 4, or an axe as at Fig. 5; it will be obvious that tools
produced in this manner will possess greater strength and durability than tools in
which the handle is formed of a separate piece.
The tools shewn on the drawings only serve as examples, as numerous other
descriptions of tools having handles, whether large or small, can be produced in the
above described manner.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. An improved manufacture of hand tools such as hammers, picks, axes, adzes and
the like, wherein the handle or shaft of the tool and the head or blade are made of a
single bar or rod, part of which is hollow for forming the handle, and part solid for
being formed into the head or blade by forging or stamping substantially as herein
described.
2. In the manufacture of tools such as is referred to in the previous claim, the
method. of forming the tools out of a bar or rod having a series of alternating solid
and hollow parts, by first cutting such bar into lengths each of which have one end
hollow and the other end solid, and then forming the solid end into the head or blade
of the tool, substantially as described.
