I, WILHELM HASSEL of Hagen in the Province of Westphalia Kingdom of
Prussia and Empire of Germany, Inventor do hereby declare the nature of this
invention to be as follows:-
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 The process of manufacturing these objects is as follows
Prismatic rolled steel pieces are prepared by forging (spring, drop, air or steam
hammer) and swaged up to the line a a (see Figures 1, 2, 3, 4, 5, 6, 7, 8 and 9 of the
annexed drawing).
يدة
The part marked by the letter din figures 1-9 forms the eye of the finished
fork for fixing the handle therein.
ப
Figure 3 of the drawing shows in dotted lines a pin 8 which has to be prepared
by forging when a pin fork is to be manufactured. The remaining prismatic part
from a a upwards (see figures 1-9) is formed by means of suitable rollers into
conical prongs or tines all having the same dimensions. The rollers are provided
with grooves corresponding to the shapes aa¹ (Figures 1-9), these grooves may
be prismatically or conically cut into the casing of the roller.

As shown in figures 1 to 9-the forks may be provided with two or more prongs
of any section The hatched parts of figures 1 to 9, indicate the swaged places or
the deepenings,which are stamped out by means of suitable tools.
The figures 3 and 3b represent a manure fork with 4 prongs and show how the
forks are afterwards treated. A rib is formed on the hatched parts by rolling and
swaging the fork; this rib is very thin and can easily be removed by stamping it
out. The prongs or tines of the forks are made by swaging or by suitable small
rollers; all four, three or two prongs are produced at the same time..

The part marked in Figures 3 and 7 by the letters T. T. is the so-called bridge
of the fork in Figures 3 and 7, this part is also indicated by the letters T. T.
The formation of this bridge of the fork by swaging is the essential point of iný
invention.

page_text: Figure 7 shows the bridge and the prongs or tines of a fork having 8 prongs or
tines; it is obtained from Figure 7 by bending up. Figure 5 represents a finished
fork with 6 prongs. The 4 middle prongs are shortened by shears as indicated in
dotted lines. The operations are always the same whatever may be the number
of the prongs.

Coke, and the like, and Apparatus therefor.
I, WILHELM HASSEL of Hagen in the Province of Westphalia, Kingdom of
Prussia and Empire of Germany, Inventor 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 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. The process of manufacturing these objects is as follows:
Prismatic rolled steel pieces, are prepared by forging (spring-, drop-, air-, or steam
hammer) and swaged up to the line a a (see figures 1, 2, 3, 4, 5, 6, 7, 8 and nine of
the annexed drawing).
The part marked by the letter d in the figures 1-9 forms the eye of the
finished fork for fixing the handle therein.
Figure 3 of the drawing shews in dotted lines a pin 8, which has to be prepared
by forging when a pin fork is to be manufactured. The remaining prismatic part
from a a upwards (see figures 1-9) is formed by means of suitable rollers into
conical prongs or tines all having the same dimensions The rollers are provided
with grooves corresponding to the shapes a¹-a¹-(Figures 1-9) these grooves may
be cut prismatically or conically into the casing of the roller.
As shown in figures 1 to 9 the forks may be provided with two or more prongs
of any section. The hatched parts of figures 1 to 9 indicate the swaged places or
the deepnings, which are stamped out by means of suitable tools.
The figures 3 and 3b represent a manure fork with four prongs and show how
the forks are afterwards treated: A rib is formed on the hatched parts by rolling
and swaging the fork; this rib is very thin and can easily be removed by stamping
it out.

page_text: The prongs or tines of the forks are made by swaging or by suitable small
rollers; all four, three or two prongs are produced at the same time.
The part marked in figures 3b and 7 by the letters T T is the so called bridge
of the fork, in figures 3 and 7 this part is also indicated by the letters T T. The
formation of this bridge of the fork by swaging is the essential point of my
invention.
Figure 7 shows the bridge and the prongs or tines of a fork having 8 prongs or
tines, it is obtained from figure 7 by bending up. Figure 5 represents a finished
fork with 6 pronge The 4 middle prongs are shortened by shears as indicated in
dotted lines The operations are always the same, whatever may be the number of
the prongs.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. A method of manufacturing forks for hay, manure, coke, and the like with
two or more prongs by machinery, consisting in making of prismatic rolled
steel pieces,
(a) the upper part T of the forks (the so called bridge) by swaging, pressing or
rolling, and then
(6) by rolling out the lower part of the prismatic steel piece into conical prongs
or into tines, all having the same dimension and finally
(c) by stamping out the rib remaining between the prongs and by bending up
the prongs and the bridge to the right form.
2. A modification of the above described method by changing the order of the
operations indicated in the first claim under (a) and (b). ·
