and other Purposes by Machinery and Apparatus therefor.
I, WILHELM HASSEL of Hagen in the Province of Westphalia and Empire of
Germany, Engineer and Manufacturer, do hereby declare the nature of this invention
to be as follows:-
The object of the present application for Letters Patent, relates to an improved method
of manufacturing forks for hay, manure, coke and the like with two or more prongs or
tines by machinery.
To manufacture forks by machinery, flat rolled steel pieces are swaged to a certain
form. The manufacture of the upper part of the forks, the so called bridge (that is,
that part, where the prongs or tines begin) is particularly difficult and requires swages
of special design, such as shewn in the Figures 1 to 6 of the annexed drawing. The
raw pieces made by means of these swages correspond to the shape of the latter and
the lower parts of the prongs are obtained by splitting up or by rolling out the raw
pieces. When the several prongs are forged out they are bent up to the right form.
The Figures 1 and 2 show the under and the upper swage of a fork having 3 prongs.
The upper swage preferably differs from the under owing to a spherical projection,
which forms the space for the handle of the fork.
The Figures 3 and 3 represent the swage of a fork with 4 prongs and show a view
of the upper swage and three cross sections of the upper and under swage. In a similar
way the Figures 4 and 5 show the swages of a fork with five and six prongs, and the
Figure 6, the swage of a fork having four prongs with an irregular cross section.
Instead of manufacturing the raw pieces of the forks by swaging they may also be
made of malleable cast iron. This method is cheaper than the manufacture by swaging
but the raw pieces of the fork are not so strong.
Dated this 20th day of March 1886.

and other Purposes by Machinery and Apparatus therefor.
I, WILHELM HASSEL of Hagen in the Province of Westphalia and Empire of
Germany, Engineer and Manufacturer, 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 the present application for Letters Patent, is to secure certain improve-
ments in my process for manufacturing forks for hay, manure or the like, with any
desired number of prongs by machinery and includes (1) swages of special design
which can be straight matrices, or also cut in the periphery of rolls for the production
of the blanks more fully described in my prior patent No. 1107%.
Such swages are shewn in the accompanying drawings, Figures 1 to 6.
Figures 1 and 2 shew swages adapted for the production of three pronged forks,
whilst
Figures 3 and 6 shew swages suitable for making four pronged forks.
Figure 4 shews a swage for a five pronged, and
Figure one for a six pronged fork.
In all these figures the upper part corresponding to the part T of the forks is of
special form for the purpose of removing from the blocks any overplus of metal.
(2) The production of the blanks from malleable cast iron or cast steel, and the
further treatment of these blanks in a similar manner to those produced by swaging
presses or rolls.
(3) The substitution in place of rolling of the prongs, of splitting and hammering out
the blanks.
The rough blocks utilised as specified in Patent No. 1107 of 1886 may be manu-
factured of malleable cast iron or of cast steel, these descriptions of iron being also
susceptible of treatment by rolling and forging.
It is stated in Patent Application No. 1107 of 1886 that the ingots for the production
of the forks are shaped by means of forging and swaging. The different swages or
forms used, which may be of any required shape can be straight matrices or may also
be cut in the periphery of rolls. The blanks produced by means of these swages are
manufactured in the manner more fully explained in application No. 1107 of 1886 into
forks with any desired number of prongs, and of any desired cross section. The upper
swage preferably differs from the under, owing to a spherical projection which forms
the space for the handle of the fork. According to the specification of application
No. 1107 of 1886 the prongs of the blanks produced by means of the above described
swages are rolled out, the prongs can however be just as well produced by splitting and
subsequent forging of the blank. The blanks can also be produced from malleable cast
iron or cast steel, as described in application No. 110780
The further treatment of the blanks so obtained is carried on in the same manner as
the pieces produced by swaging presses or rolls.

page_text: 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. The swages or moulds illustrated in Figures 1 to 6, which are applicable either
as flat or straight matrices, or cut in the periphery of rollers for the purpose of shaping
the rough blocks set forth in my patent No. 1107 of 1886.
2. The manufacture of rough blocks, either swaged, pressed or roller moulded as
herein before set forth, from malleable cast iron or cast steel and the preparation of the
finished articles therefrom.
3. The method of dividing the prongs by splitting or hammering out the same in
place of moulding.
The whole substantially as described and illustrated in the accompanying drawings.
Dated this 10th day of December 1886.
