Improvements in Bevel Gearing.
I, JOHN BROWNE of 10 Mildmay Road, Stoke Newington N. in the County of
London, Engineer, 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 improvements in bevel gearing, and has for object to
produce such a gearing which shall have great power, and also be easy in running,
and which shall be specially adapted for use as a driving mechanism, or a
transmitter of motive force.
In this connection such a gearing will be of great advantage for use upon
motor cars, cycles, and other vehicles; and again in mills, factories and other
places where either equal or varying speeds are required.
In accordance with this invention I form the teeth of the gear wheels with a
channel across their bearing faces, making as it were two sets of teeth upon each
wheel, thereby giving a duplicate or double bearing or thrust to the gearing;
and between the teeth I make apertures or perforations through the thickness
of the metal forming the wheel, through which the lubricant may freely pass.
Again, I make the wheels with either a concave or a flat back that they may
be placed in position square with an enclosing casing or frame, in which I prefer
to fit the gearing, and this casing may be provided inside with a hanging bracket
to form a bearing for the spindle of one of the wheels, the other wheel being
carried upon the main or bearing shaft or, axle which is carried through the
casing or framing aforesaid.
And in order that my invention may be fully understood, I will describe same
with reference to the accompanying drawings of which Fig. 1 is a plan view of a
bevel gearing constructed in accordance with this invention, and Fig. 2 a side
elevation of the same, the casing being in section. The gearing is shewn as placed
within a protective casing which may be opened or closed as required.
a is the
casing above referred to; b the main or driving shaft upon which is mounted the
wheel c. The wheel d gears with the wheel c, and is supported upon the pivotted
spindle e carried by the hanging bracket fattached to the inside of casing a in a
suitable and convenient position and manner. g is a channel formed around the
toothed wheels dividing the teeth into two portions and making two sets of such
teeth upon each wheel. hh are apertures or perforations made in the metal of the
wheels between their teeth through which the oil or other lubricant used is free to
pass. As will be observed upon referring particularly to Fig. 2, I make the
wheels so that their backs may lay flush against the casing and thus economise
space, for this purpose 1 may make the back of the wheel concave as shewn at i
(see wheel c) or flat as at k (see wheel d).
The two sets of teeth upon the face of each wheel gearing with one another
afford a double or duplicate gear giving great power; and the channels g and.
perforations permitting of perfect and free lubrication afford very easy running.
When employed as a driving mechanism or brake actuating gear such as upon
motor cars, cycles and other vehicles; or as a power transmitter such as in mills,
factories, and the like, the bevel gearing above described will be found to possess
advantages over other gearing heretofore in use.

page_text: 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 I
claim is :-
1. The improvements in bevel gearing hereinbefore described and shewn.
2. In bevel gearing the construction of a toothed wheel with a channel across the
face of the teeth and with apertures or perforations through the metal between the
teeth substantially as shewn and described.
3. In bevel gearing adapted for use as a driving mechanism or power transmitter
the combination of toothed wheels having channels around the toothed faces of the
wheels & apertures or perforations through the metal between the teeth, with an
enclosing casing having a hanging bracket therein and a pivotted support for one
of the wheel spindles; substantially as hereinbefore described and shewn.
Dated the 5th day of January 1897.
J. BROWNE.
