PROVISIONAL SPECIFICATION,
Improvements in Gear Wheels for Motor Cars or the like.
I, CILARLES MANNERS, of Edenbank, Mansfield, Nottingham, Gentleman,, do
hereby declare the nature of this invention to be as follows:-
-
This invention relates to certain improvements in gear wheels for motor cars
and the like and has for its object to reduce as far as possible the noise produced
both by the actual vibration of the running machinery of which the gear forms
part and that caused by the jolting of the car or the like when running over
uneven or rough roads.
In carrying the invention into effect I provide either one of the wheels with
wooden teeth and I form a small pad or block of any suitable material which is
secured to the wheels between each of the teeth so that the teeth of the wheels
bed therein during their rotation. I may instead of plucing the pad aforesaid
between and at the base of the teeth cover the tops of the teeth with a suitable
pad which will serve a like purpose.

I, CHARLES MANNERS, of Edenbank, Mansfield, Nottingham, Gentleman, 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:-

between and at the base of the teeth cover the tops of the teeth with a suitable
pad which will serve a like purpose.
In order that the invention may be the better understood drawings are
ennended.

page_text: Fig. 1 being an elevational view of a pair of wheels.
Fig. 2 is an enlarged detail showing a method of applying the pad or block
to the tooth of a wheel. a and are respectively a wheel provided with wooden
teeth c. and teeth e, formed solid with the body of the wheel. d and f indicate
Dads of rubber, leather or other suitable substance secured between each tooth.
The aforesaid pads or the like may be secured to the wheels in any suitable
manner for example some adhesive substance may be employed or, as illustrated
in Fig. 2. a channel having inclined sides may be cut in the wheel or the top of the
tooth and the leather or other substance employed may be wedged therein, any
transverse displacement being prevented by means of the metal ring one of
which rings may be secured at each end of the pad. The pads may be applied
either to the base of the teeth or as shown at q Fig 2, they may be secured to
the top of the tooth and to one only or both wheels as may be found in practice
to be necessary.
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. The improvements in gear wheels consisting in the provision of a pad of
some resilient or yielding substance at the base or ton of the teeth of such wheels
substantially as herein described and illustrated by the appended drawings.
2. The combination with a gear wheel of pads or blocks of rubber. leather or
other suitable material secured thereto by means of channels cut at the base or
top of the teeth into which the leather or the like is wedged, and a ring or rings
to prevent the transverse displacement of the block substantially as bercin
described and illustrated in the appended drawings.
