Improvements in Machines for Mixing Syrup.
1, JOHN WERNER, of Number 8 The Highlands Street, in the City of
Rochester, County of Monroe and State of New York, United States of America,
Manufacturer, 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 stateinent :-
This improvement relates to machines for mixing syrup, in which spirally-
ribbed rollers force the syrup forward through a casing. The invention consists in
the construction and arrangement of parts hereinafter described and claimed.
In the drawings-
Fig. 1 is a plan view of the machine, with the top plate removed;
Fig. 2 is a longitudinal, vertical section of the same in line - of Fig. 1;
Fig. 3 is an enlarged cross section in line y-y of Fig. 2;
Fig. 4 is an elevation of the gearing;
Fig. 5 is a longitudinal, vertical section of one of the journal bearings;
AA indicates a four-chambered casing, in which are located, in pairs, four
spirally-ribbed rollers B B and B B', two above and two below, with a partition a
separating them. The rollers are so disposed that the two upper ones, B B, feed
the syrup forward from the entrance spout to the opposite end of the machine,
where it falls through an opening c in the central partition, and is then fed back
in the reverse direction by the rollers B' B', and is finally discharged at the exit
spout d into a suitable receptacle. The journals of the rollers extend through
the ends of the casing and are driven by a set of gears 1, 2, 3, 4, 5, 6, so arranged
that the two lower rollers B B₁ run faster than the upper ones, thereby always
insuring a free discharge and preventing any clogging.
The
Each of the rollers is made in sections fff by turning V shaped grooves at
intervals in the roller down as deep as the spiral ribs 9 g, or deeper, and in these
grooves rest V-shaped flanges h h of the casing fitting closely therein.
flanges extend only half way round and rest in the lower half of the grooves,
thereby leaving the top surface of the rollers entirely open and forming a passage
way for the syrup over the top of the rollers from end to end of the machine.
The flanges by fitting in the lower half of the grooves effectually cut off the
passage of the syrup under the rollers, forming stops and causing the spiral ribs
of the rollers to force it to the top. The spiral ribs incline outward and upward,
whereby the tendency is to carry the syrup toward the center, thus facilitating its
passage and thoroughly grinding it up.
over the
kk are two independent heads of the two upper rollers, located at the discharge
end, or the end away from the feed spout, and provided with spiral ribs standing
at the reverse incline from those on the sections ff of the rollers. A space!
is left between these heads and the sections ff, which space comes
discharge opening c. The object of these independent heads is to oppose the
current of syrup passing through the upper chambers and force it back so that it
will discharge through the opening c, also prevent the passage of the syrup
outward around the journals of the rollers through the casing, which it tends to
do under the great pressure to which it is subjected. Similar independent
heads kk are located at the discharge end of the lower rollers for a similar
purpose, viz., to force the syrup down into the exit spout d, and to prevent the
syrup passing through the journal openings.

page_text: mm are the journal bearings at opposite ends of the machine, each holding the
ends of the journals. These bearings are located away from the ends of the case,
as shown, so as to leave a clear space between the ends of the case and the
bearings, the journals being uncovered in that space. The boxes are provided
with oil holes, and. beneath the boxes are discharge passage n n extending through
the bearings longitudinally, by which means such oil as drips down is discharged
at the end. By the means above described no oil passes inward through the end of
the case to come in contact with the syrup.
The machine can be made effective, with only one pair of rollers, the case in
that instance being single instead of double, and the discharge spout d, being
placed at the point where the opening c is located.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed, I declare that what I
claim is,
1st. In a syrup mixing machine, the combination of a pair of spirally-ribbed
rollers provided at intervals with circumferential grooves, and a case containing
the rollers provided with flanges resting in the lower part of said grooves and
extending but partially around the rollers, leaving the top of the rollers uncovered,
as and for the purpose specified.
2nd. In a syrup mixing machine, the combination of two pairs of spirally-ribbed
rollers provided at intervals with circumferential grooves, and a case containing
the rollers, said case provided with a partition separating the pairs of rollers, and
. with flanges resting in the lower part of the grooves and extending but partially
around the rollers, leaving the top of the rollers uncovered, as and for the purpose
specified.
3rd. In a syrup mixing machine, the combination of a case, a pair of spirally-
ribbed rollers resting in the case, and heads at one end of the rollers separated
therefrom by an intervening space, said heads provided with spiral ribs standing
.reversely to those on the rollers, as and for the purpose specified.
