Improvements in Machinery for Rolling Tealeaf.
I, NATHAN WILLIAM HORATIO SILARPE, of 65, Burgoyne Road, Harringay,
London, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to machinery or apparatus for rolling tealeaf in which
there are opposing plates or surfaces (usually or partly dished) both of which have
motion imparted to them for effecting the rolling or curling of the leaf. The
object of my present invention is to double or treble the efficiency of such
machinery by the simple addition and extension of some of the parts thereby
effecting a great saving in the wear and tear and in the amount of power required
for driving.
In this class of machines as ordinarily constructed there are generally three
compound or double throw cranks for operating and guiding the said plates
or surfaces; each crank shaft being provided with two cranks or crank pins,
one for operating and guiding the upper plate or surface and the other
for operating and guiding the lower plate or surface. And there are also
machines employing three single crank shafts for working the lower plate or
surface while the upper receiving receptacle and surface are quite stationary.
These machines are generally made in the form of a tripod and it has occurred
to me that a double tripod formed by the addition of a fourth compound or
single crank as the case may be on the opposite side to the compound crank
employed for driving these machines and the extension of the lower rolling
plate or surface and the addition of a second rolling plate would enable me to
double the output of the machine.
My invention may also be made with two compound or double throw cranks,
one crank being at each end of the 'tripod and in the centre of the tripod four
single cranks, two on each side.
To treble the efficiency of the machine I would duplicate the additions as
above to the other side of the tripod.

in and by the following statement:-
-
My invention relates to machinery or apparatus for rolling tea leaf, in which
apparatus or machinery as usually employed, there are opposing plates or sur-
faces which are dished or hollowed and both such surfaces have motion imparted
to them for effecting the rolling or curling the leaf, which latter operation is
effected while the leaf is between the two surfaces.
In this class of machines as ordinarily constructed there are generally three
compound or double throw cranks by' which the plates or surfaces are operated
and guided, each crank shaft being fitted with two cranks one for operating
and guiding the upper plate and the other for the lower plate. Machines
have also been proposed where three single crank shafts are employed for the
lower plate, while the upper receiving receptacle and surface are quite stationary.
Now the object of my present invention is to greatly increase the efficiency
of such machinery by the addition to and the extension of some of the parts,
and thereby effect a great saving in the wear and tear and in the amount of power
required for driving.
Heretofore such machines for rolling tea leaf have generally been made in the
form of a tripod, the, lower plate or surface and the upper plate or surface have
commonly been supported by the cranks at three separate points respectively
but according to my present invention I form a machine in the form of what
may call a double tripod, by the addition of a fourth compound or single
crank, the extension of the lower rolling plate or surface and the addition of a
second upper rolling plate, all as hereafter described.
I will now describe my invention with reference to the accompanying draw-
ings Fig. 1 being an elevation and Fig. 2 plan view showing an example of
construction of my improyed machine. I provide a fixed framework A, sup-
ported by three pedestals A¹, and a fourth pedestal A2, all these pedestals being
secured to the bed plate of the machine. The pedestals A¹, A², receive and
form bearings for four vertical shafts B each formed above the frame A, with
a crank B¹, above which there is again a second crank B2, C, is a framework
which may be of rectangular form having bracket bearings C, which take on to
the cranks B', whereby the frame C is operated and supported. This frame C
carries a horizontal plate which is dished and forms the lower rolling plate
marked C³, in Fig. 2.
The upper cranks B², enter bearings formed in a horizontal extending upper
frame D, and this frame I form with two apertures to receive two leaf con-
taining boxes E, into which the leaf to be rolled is placed. The upper dished
rolling surfaces are located within these boxes above the leaf within, as is com-
mon with these machines and are indicated by the letters F, and means are
provided as usual, such as a hand wheel operated screw as indicated
at Fig. 2 by which the height of the upper plates F, are adjusted,
but as such adjustment is common, it is not considered necessary to further
illustrate or describe same.
One of the double crank shafts B is driven by pulley G, on horizontal shaft G¹,
connected with the crank shaft B by bevel gearing. It will now be obvious
that if desired I may dispense with the two double throw cranks on each side
of the machine and employ therefore four single cranks, two of such supporting
the lower frame C, two the upper frame D, and this without departing from my
invention.
Having now particularly described and ascertained the nature of this in-
vention, and in what manner the same is to be performed, I declare that what
I claim is
1. The improved machine for rolling tealeaf wherein the size or capacity
of the upper and lower rolling surfaces are increased and the same are supported

page_text: by the addition of an auxiliary double throw crank shaft whereby the efficiency
of the machine is greatly increased without a proportionate increase in the
amount of power required to drive same. substantially as described with reference
to the accompanying drawings.
