Improvements in Means for Guarding or Protecting Gear Wheels
in Tea Leaf Rolling Machines and the like.
I, WILLIAM JACKSON, of Thorn Grove, Mannofield, Aberdeen, Scotland,
Engineer, do hereby declare the nature of my invention to be as follows:-
My invention has for its especial object to provide means for guarding or
protecting the gear wheels at what is known as the main driving bracket of
tea-leaf rolling machines, and I will describe it in connection therewith although
it is not limited to that particular application.
According to my invention the main driving bracket is constructed in such
a form that it presents openings by which access to each of the wheels can be
obtained which openings are provided with doors or covers so shaped to corres-
pond with the form of the bracket around the said openings that when these
doors or covers are put in place and secured they constitute with the bracket a
complete covering for the wheels which are thereby completely guarded and pro-
tected and the tea is prevented from coming into contact with the said bevel
wheels and the lubricant thereof.
I preferably provide two doors or covers one above and one below these with
the main body of the main driving bracket constituting a protecting or guarding
device in three pieces secured together so as to make one body covering the
wheels.

I preferably provide two doors or covers, as illustrated in the accompanying
drawings, these with the main body of the main driving bracket constituting a
protecting, or guarding, device in three pieces secured together so as to make
one body covering the wheels. Figure 1 being a plan, Figure 2 a side elevation,
Figure 3 a longitudinal section, Figures 4 and 5 are elevations of the two ends.
A, B, are the bevel toothed wheels which are secured to the shafts a and b
mounted in the main body part C of the bracket in which there are openings dc.
off a size to allow of access to, and the passage of the respective wheels A, B.
The opening d is covered by a door or cover D hinged at 2 and secured by a
bolt and nut at and the opening e is covered by a door or cover E secured by
a bolt and nut e².
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is:
1. A main driving bracket for containing the gear wheels of a tea-leaf rolling
machine, or the like, the said bracket being made in parts consisting of a main
body part with openings therein by which access can be obtained to the gear
wheels, and doors or covers shaped to cover the said openings and means for
securing the said doors or covers in place so that the structure as a whole encases
or covers the said wheels, substantially as herein before described.
2. A main driving bracket for tea-leaf rolling machines, or the like, the said
bracket being constructed as herein before described and illustrated in the accom-
panying drawings.
