COMPLETE SPECIFICATION.
Machinery for Production of Balls or Pellets from Wire.
We, ENGLEBERT FRIES and WILHELM HÖPFLINGER, Schweinfurt in the
Empire of Germany, 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 invention consists in a machine for producing balls or pellets from.
wire and it is illustrated in the annexed drawings.
Fig. 1 shows a side view of the machine part in section.
Fig. 2 is a plan of the machine part in section.
Figs. 3-4 are detail views.
尊
The machine consists of an apparatus for uninterruptedly feeding the wire which.
is to used and of a cutterhead which shapes and severs balls or pellets from the end
of the continually advancing wire; a is a rotary bobbin of the wire to be worked.
The mechanism for feeding straightening and straining the wire consists of 2 pairs.
of taking in rollers c'c which revolve in brasses in the frame zone over the other,.
of several small straightening cylinders d d and 2 pairs of straining rollers e e one
over the other. f is a nozzle through which the wire bis directed to the cutterhead
which will be hereinafter described.
The cylinders cc and ee are driven from the conical pulley p on the shaft r.
The movement of the shaft r is transferred by the spur wheels on the shaft r to
the spur wheel t of the worm shaft u. The latter revolves in the bearings v v and.
gears with the worm wheels x and y y which are keyed upon the shafts of the
lower rollers c c and e e.
The mechanism for shaping the balls from the wire consists in the cutterhead g
on the mandrill in the head stock h and revolved by the pulley w so as to make.
450 to 500 revolutions a minute.
The cutterhead 9 (Fig. 3) is provided with 3 steel knife dises mm ou the
periphery of which half round hollows (Fig. 4) are sharply cut or made the size of"
which corresponds to the size of the balls to be produced. The cutting discs m m are
mounted on the trunnions n n which revolve in red brass collars in the blocks o o-
which can be approached and removed one from the other as it is necessary by
means of set screws in guides on the cutterhead 9. The cutterhead g is surrounded
with a protecting case q.
The operation of the machine is as follows:-
The wire 6 from the bobbin a is taken in by the pairs of rollers c c and passed.
between the straightening cylinders d d wherefrom it passes between the straining
cylinders ee and into the nozzle which conducts it to the revolving cutterhead..
The latter by its rotation continuously cuts off and shapes with the cutting
discs m m balls of the same size.
By the continuous advancing of the wire b against the cutting discs m m the
latter are turned in their bearings o o.
The machine may be worked uninterruptedly and possesses therefore extraordinary
efficiency in production.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A machine for producing balls or pellets from wire by a revolving cutterhead g
the cutting discs m m of which are provided with hollows corresponding to the size

page_text: of the balls to be made and which are turned round their axes by the continuous
advancing of the wire b.
2. A machine as described in Claim 1 the cutting discs m m of which are adapted
to be approached to or withdrawn from a common centre.
3. A machine as described in Claims 1 or 2 the wire b to be worked is fed
straightened and stretched by the cylinders cc,d d,ee, and conducted uninterruptedly
to the revolving cutterhead g.
