A New or improved Apparatus for manufacturing dalis.
JOSEPH MITCHELL, 7, Ten Acres, Pershore Road, Birmingham, Ball Maker, do
hereby declare the nature of this invention to be as follows:-
The object of my new, or improved apparatus for manufacturing balls, for cycle
machines, & other purposes, is to manipulate with accuracy, & quickness bars
into balls for bearing purposes. In carrying out my improvements, I construct
a round disk upon the face of this disk, round its circumference, I form a ridge
two inches deep, & one inch wide more or less, in the centre of this ridge I make
a groove, the size of the balls, I wish to form. On each side of this groove, I bevel,
leaving a sharp knif steel cutting edge round groove. Another disk in like manner
I form. These 'two disks, I fix upon two face plates, for their grooves to work
together, face to face, & revolve upon spindles in different directions to each
other, & by lever pressure to open & close. Operation-When my new or improved
apparatus for making steel balls is in working position, upon their face plates,
vertical, horizontal or any angle, I feed it, with a number of bars working against
stops & the disks are revolving at a great speed, in opposite directions to each
other cutting small pieces from the bars, which fall between the grooves of the two
disks & they roll & revolve therein, & pressure being applied are quickly formed
into balls. The apparatus is opened & the balls fly out & the bars are again
applied, & so on while the process of manufacturing is going on.
JOSEPH MITCHELL, 7, Ten Acres, Pershore Road, Birmingham, Ball Maker, 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 my new or improved apparatus for manufacturing ball's, for cycle
machine's, & other purpose is to manipulate, with accuracy & quickness bar's into
ball's for bearing purposes-In carrying out my improvements, I construct a round

of the balls, I wish to form. On each side, of this groove, I bevel, leaving a sharp
knif steel cutting edge, round the groove. Another disc, in like manner, I form.
These two disk's, I fix upon two face plates, for their groove's to work together, face,
to face & revolve upon spindles in different direction's to each other, & by lever, or
automatic pressure, to open, or close.--Operation, when my new,
apparatus, for making ball's, is in a working position, in a machine, upon their face
or improved,
plates, vertical, or horizontal, or any angle, I feed it, with a number of bar's
working automatically in, & out of the discs, against stop's, & the disk's are revolv-
ing at a great speed, in different directions to each other, cutting small pieces, from
the bar's as ball's, which fall between the groves of the two discs & the balls revolve
& roll therein, & pressure being applied automatically or otherwise, are quickly,
formed into balls, ready for polishing,. The, apparatus is opened, & the balls fly
out & fall into the receiver's & the bar's are again applied, & so on while the process
of manufacturing is going on, making ball's from cold bar's of steel-or other
required material.
In order, that my invention, may be fully understood, I will now, more particu-
larly describe it, with the aid of the accompanying drawings, in which similar
parts are marked, with like letter of reference.
Fig. 1. Represents an elevation, of my ball apparatus in a machine, & showing
a section of the top, & bottom discs, with cylinder, or rim, or ring, wherein the bar's
are worked through to the discs..
Fig. 2. Represents. a, plan of the bottom disc, with ring,, or cylinder, &, showing
end's of the bar's upon the outside knif edge, of the disc, ready for, the top. disc, to,
be pressed, with its knif edge,, upon, the bar's to cut,, & form them, into ballis.
Fig. 3 Represents a plan of the bottom disc as in Figure 2,, but with the ball's.
cut from the end's of the bar's, &, the bar's, are withdrawn from, the disc; & resting.
upon the cylinder, or rim, of the machine.
Fig. 4 Represents a plan, of the bottom disc;, as in Figure 3, but with the balls,
flying from the disc, (when they are opened, or drawn apart) & finding their way, to
the receivers.
Fig. 5 Represents a plan of the top, & bottom disc, with their raised knif edges,.
for cutting & forming the balls, from the bar's, also the grooves wherein, revolve.
& roll, the ball's after being cut, so as to remove, the surface, or roughtness from,
theni.
Fig. 6 Represents a section, of the top,. & bottom disc with half formed ball, on.
the end, of the bar, & the same ready, to enter between the discs.
Fig. 7 Represents a section, of the top, & bottom disc, closed, with the bar end
ball, between the two discs, & the ball almost cut therefrom.

roughtness, e, knif edge, on the groove, f, face plate, of machine, to carry the disc,
h, bar, j, cylinder, or rim, or ring, i half formed ball, on the end, of the bar & the
bar, with drawn from the disc, k, hole through rim for the bar, to work through to
the discs, 1, bar in the cylinder, or rim of a machine, ready to enter between the
two discs, m, ball almost cut from the end of the bar by the knif edge, of the top,
& bottom discs, n, opening for the balls to pass to the receivers, 9, spindle of the
top disc, s, a spring to lift top disc, from the bottom disc, t, handle lever, or screw
r, receiver.
Having now. particularly described & ascertained the nature of my, said
invention, & in what manner the same is to. be performed, I declare that, what..
I claim is:
1st. A disc, round its flat edge, a hollow groove with two knif cutting sharp
edges, round the circumference of its edge, for ball making, as set forth described,
& illustrated in the accompanying drawings.
2nd. Two of these discs, working, with their grooves face to face, & revolving.
in different directions to each other, & at any angle, in a machine, actuated

manufacturing balls.
