COMPLETE SPECIFICATION.
A New or Improved Machine for Rectifying Steel or other Balls.
We, AUGUSTE Henri DupeyRON and EDOUARD ALPHONSE PHALEMPIN, both of
14, Rue Oberbampf, Paris, in the Republic of France, Mechanical Engineers, 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:-
-
Our invention relates to a machine for rectifying balls such as the balls of the
bearings of bicycles and carriages and others, and based upon a new principle,
assuring their sphericity in a simple and exact manner and at the same time
having a considerable efficiency of out put.
In the annexed drawing
Fig. 1 is a diagrammatic view of the rectifying plate.
Fig. 2 elevation of the ball rectifying machine.
Fig. 3 partial plan view of this machine.
The chief parts of our machine are two plates A and B engraved with diametri-
These furrows extend in
cal furrows a and b in opposite directions, see Fig. 1.
tapered form one a towards the lower end and the other towards the top, more-
over both are striated finely enough along their whole length or along a part of it,
to serve, when moved, as cutting files. In the beginning of the operation, the
slope yy of the plate B is placed at some millemeters below the slope xr of
the plate A and a rough ball is brought in on the top of the furrow b at this
moment the plate A goes upwards whilst B goes downwards, and the ball runs
through the two furrows but remaining at their intersections, it is rolled there
upon all its surface and being properly cut thereby it passes out absolutely
spherical.
This is the principle of the machine and we will now describe its manner of
construction.
Each of the plates A and B is constructed as described and is joined to a
connecting rod c or d articulated to a shaft e with double crank and slides in
a guiding frame a¹ or b₁ the lateral parts a² or b² of which can be pressed or
loosened by the screws a³ or 63 in order to regulate exactly the position of the
corresponding plate.
On the same base plate C which carries the guides a¹ bare fastened two
frames and E, the first 1) carries a shaft f upon which are mounted the fast
and loose pulleys f¹ 2 receiving the movement of a strap driven by any motor,
the fly wheel and the pinion f; this latter gears into the wheel e¹ keyed on
one of the extremities of the shaft e.
The ball feed comprises a hopper g from which a tube g¹ passes ending at its
lower end in front of a socketed wheel k mounted on the shaft of a toothed
wheel, this toothed wheel engages with a pinion acting also as a ratchet,
when moved by a hook-like deg o, the point of which is articulated so that

page_text: its ascending movement operates the pinion and its descending movement i
without any action on this pinion.
The dog o is moved by an eccentric m mounted on the shaft e and is guided in
a support o fastened on the framing E.
An inclined tuber goes from the wheel k to a point in the guide a where it
is perforated by a hole which at the proper time communicates with a cavity
of the plate A at the beginning of the furrow a. When the belt is on the fast
pulley 3 the pinion f communicates the rotation to the wheel e¹ and the crank
shaft e, the connecting rods c and d lift alternately each of the plates A B whilst
the other falls. The eccentric m communicates to the dog o an alternative
vertical and rectilineal movement and during its rising the pinion is caused
to turn the wheel kone step by means of the wheel k. A ball descends from the
tube g¹ to fill each socket as it presents itself opposite the end of the tube, and
as soon as the plate A arrives at its lowest point, a ball passes to the entrance of
the furrows a and b, the rectification of the ball is effected as described above.
The ball then leaves the furrows and falls into a receiver arranged for this
purpose and the same phenomena continue automatically as long as there are
balls in the hopper g or in the tube g¹.
In the drawing we have shown each plate A and B provided with only one
furrow, but it is evident that they can have several of the same or of different
diameter, moreover one of the plates may be fixed and the other movable without
altering the scope of our invention.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. A machine for the rectification of balls comprising in combination two
plates provided with rectilinear furrows, totally or partially striated, receiving
at their beginning the rough balls in order to pass them to their extremities by
the rectilineal alternative movement of the two plates or of one of them only in
order that they may be treated by the cutting surfaces of furrows and issue
perfectly rectified, the balls being fed to the plates or their equivalents by nieaus
of a feed with socketted wheel substantially as described and shown in the annexed
drawing.
2. In the machine for rectification of balls a feed comprising a wheel with
sockets turnel periodically by ratchet gear this wheel receiving the balls from
a hopper by one or more feed tubes and bringing them successively into one or
more tubes guiding them to the place or places where they are received by the
parts of the machine intended for rectifying them, substantially as described and
shown in the annexed drawing.
