I, HUGH WATSON MACKENZIE, of 26, Glebe Street, Loughborough, in the
County of Leicester, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to dough kneading and rolling machines, such as used
in the manufacture of biscuits, and has reference more particularly to the
arrangement for operating the rollers.
According to the said invention, the roller spindles are in gear with a counter
shaft on which are two belt-pulleys driven in opposite directions by different
loops of the same driving belt, suitable guide pulleys being provided to form the
necessary loops in the belt. Between the belt pulleys is a clutch whereby either
one or the other can be locked to the counter shaft according to the direction
in which it and the rollers are to be driven. The top roller may be counter
weighted, and is arranged to move up and down in the frame of the machine,
and its gear has a feather and groove connection with the countershaft to permit
of such movement.
By means of my invention the spur gearing and open and twist belt gearing
heretofore employed are dispensed with; the cost of the machines is reduced,
and they work with less friction and noise than do such machines as previously
constructed.
Improvements in Dough Kneading and Rolling Machines.
I, HUGH WATSON MACKENZIE, late of 26, Glebe Street, Loughborough, in the
County of Leicester, and now of 68, Gorgie Road, Edinburgh, in the County
of Midlothian, Engineer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and

page_text: ascertained in and by the following statement, reference being had to the
accompanying drawings and to the letters and figures marked thereon, that is
to say:-
This Invention relates to dough kneading and rolling machines, such as
used in the manufacture of biscuits for rolling the dough. into sheets ready for
the cutting apparatus, and for kneading bread doughs..
The said invention has reference more particularly to the arrangement for
operating the rollers, and is designed to enable the usual spur gearing and
open and twist belt gearing to be dispensed with, thus reducing the cost of
manufacture and causing the machines to work with less friction and noise
than heretofore.
According to my invention, the roller spindles are in gear with a shaft on
which are two belt pulleys, driven in opposite directions by different loops of a
single driving belt, suitable guide, pulleys being provided to form the necessary
loops in the belt. Between the belt pulleys is a clutch whereby either one or
the other can be locked to the shaft, according to the direction in which it and
the rollers are to be driven. Thus, after the dough has been rolled in one
direction, it is only necessary, in order to roll it in the opposite direction, to
reverse the aforesaid clutch.
.
And in order that my invention may be readily understood, I will describe
the same fully with reference to the accompanying drawings in which:
Figs. 1 and 2 are respectively end and side elevations, and
Fig. 3 is a plan, of a machine embodying my present improvements.
Fig. 4 is a diagrammatic view of the gear.
a and a are the two oppositely driven belt pulleys, and 6 is the shaft on
which they are loosely mounted. This shaft is vertical and is in gear, by means
of a pinion and crown-wheel with the axle d of the lower roller, whence
the motion is communicated to the axle № of the upper roller through a train
of gear wheels e.
fand fare respectively the sliding and the stationary portions of the clutch
for locking one or other of the pulleys a, a, to the shaft b. The portion f
is moved up or down on the shaft b, in the usual manner, by a forked lever g
pivotted on a bracket g', and is suitably toothed to engage corresponding teeth
on the stationary portions f¹ which are secured to the pulleys.
h, h, are the guide pulleys round which the belt A (Fig. 4) passes in order
to form the loops for driving the pulleys a, a in opposite directions. These
guide pulleys are mounted on a spindle carried by a pair of arms i¹ pivotted
on a shaft 2. This enables the belt to be tightened up, as required, for which
purpose the spindle i is moved outward more or less by means of an arm j
rigidly secured to it. This arm is connected at its upper end to a link j¹ formed
of a left and right hand screw working in correspondingly threaded hub of a
hand-wheel, so that by turning said handwheel the tension of the belt can
be altered.
is a guide pulley for the portion of the belt immediately coming from the
counter or driving shaft in the factory, or bakery, or returning to the said
shaft, according to the direction, as the case may be.
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:
1. A dough kneading, or rolling machine having its rollers actuated from a
single driving belt operating through the medium of a pair of oppositely driven
pulleys in combination with a clutch which enables one or other of the pulleys
to be thrown into gear as required, substantially as described.
2. In a dough kneading or rolling machine, the improved means for driving

than heretofore, substantially as hereinbefore described with reference to the
annexed drawings.
