A Machine for Forming Raw Material for Manufacture of Cement
and similar Plastic Substances into Balls.
I, CARL BRENTANO, of Monchenstein, Basel, Switzerland, Manufacturing
Manager, 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 :-
This invention relates to a machine for forming raw material for manufacture of
cement and similar plastic substances into balls.
This machine principally consists of a rotating drum which on its circumference
has parallel annular grooves of semi-circular or nearly semi-circular section, and of
a mantle which encompasses about half the drum, and is also furnished on its inner
level with grooves the section of which is semi-circular or almost semi-circular.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawing which I will now
proceed to describe.
Figures 1 and 2 represent the machine in two perpendicular sections.
Figure 3 is a section of the mantle through the line X X of Figure 1 ;
Figure 4 is a section through the lines Y Y of the same figure.
and
The machine consists of a rotating drum A of any suitable metal, and mantle
which encompasses the drum A about half its circumference. The drum A is fixed
on a shaft a, which is placed in suitable bearings bb, and which can be propelled
by a handle c, a belt-wheel, or cog-wheel, etc. On its exterior this drum A is
supplied with annular parallel grooves d, the cross section of which is semi-orbicular
or nearly so.
g is
The mantle B of suitable metal is also arranged with grooves e which are
situated opposite the grooves d of the drum, and the cross section of which is
similar to that of the grooves d. The mantle. B consists of a lower part of fastened
by bolts i, and an upper part g to be fitted in. The lower part of the mantle is
placed concentrically to the drum A, whereas the upper part of the mantle

the mantle there is a bearing h which with the same is cast out of one piece, and in
this bearing h, open at the top rests a bolt k fastened by screws ; to the upper part g
of the mantle so that the said upper part 9 can be turned by the bolt
bearings h, and opposite the drum A be brought in the desired position. This is
effected by means of the rod 1, which on its ends is connected with a fixed piece m
to the upper part g of the mantle, and is borne by its other end, supplied with a
worm, by means of screw-nuts O in a bearing D. The latter is fixed by screws n
to the lower mantle part.
in the
Should the upper part g of the mantle opposite the drum A be fitted in, it is
sufficient by slackening the one screw-nut O and turning on the other to adjust the
rod in the one or the other way, whereby the latter rod will turn the upper
mantle part round its bolts in the bearings h. The upper mantle part will

respective side-cars r of the mantle part g and the horizontal grooves of the lower
mantle part f.
In order to use the machine for forming raw material for manufacture of cement
and similar plastic substances into balls, the following direction is given. The
cylindrical lumps or pieces of plastic cement-raw-material, or other substance
coming forth out of the mouthpiece of a string-press containing a certain number of
round openings will be cut off in a well known corresponding length of the breadth
of the groove-drum. The diameter of the lumps or pieces thus obtained must be
of the kind that a part of same-the length must be equal to the groove-diameter
has the same volume as the ball to be formed, that is to say the diameter of the
lump or piece must be in comparison with the diameter of the ball like V 2 V 3.
These lumps or pieces will then be brought at V between the rotating drum A and
the mantle B into the grooves d and e, whereby the rotating drum A in the direction
of the arrow a draws these lumps or pieces into it, rolling themselves round in the
grooves de, and they come out at U as round balls from the grooves of the
machine d and e.
To prevent any obstruction in the grooves d and e it is advisable to arrange
either the bearings bb of the drum shaft a opposite the mantle B or the latter
opposite the drum adjustable-in order to remove any such obstruction-thus to
make the admission between drum A and mantle B possible.
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
A machine for forming raw material for manufacture of cement or other similar
plastic substances into balls constructed substantially as hereinbefore described and
shown on the accompanying sheet of drawings.
