Improvements in Bevelled Glass Polishing Wheels, Carriage Wheels,
Machinery Wheels, and the like put together in Segments.
CHARLES THOMAS HORNSEY, 118, Portway, West Ham, Essex, do hereby declare
the nature of this invention to be as follows:
The properly securing the joints of the segments whereby they are made per-
fectly rigid and cannot in their working either by occilation jerking, shaking or
movement become loose or detached and thereby all risk of accidents is entirely
obviated while as a consequence greater uniformity exactness and perfect finish
is executed in the work done by the wheel. The manner in which the segments
that go to build up the annular ring that forms the polishing surface of the disc
wheel are connected together and consists of forming in one end of such a seg-
ment a groove or recess of any suitable form and in the other end thereof a
projection or raised portion so that when building up the said annular ring the
projection or raised portion at the end of one segment will correspond to the
groove or recess of the next and when such ring has been completed it can be
attached to the metal disc by means of a few screws or the like. My invention
can also be applied to the segments that go to make up the rims of vehicle
wheels, machinery wheels and the like.

I, CHARLES THOMAS HORNSEY, 118, Portway, West Ham, London, E., Cricket
Bat Maker, 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:-
My invention relates to improvements in the construction of bevelled glass
polishing wheels, vehicle wheels and all other wheels that have a rim or ring
built up of segments, the objects of which are, to form a more secure connection
between the ends of the segments than has hitherto been attained with wheels.
similarly constructed and at present now in use, and with respect to bevelled
glass polishing wheels, to obviate the serious accidents that occur through the
flat ended segments that form the polishing surface thereof coming apart and
[Price Sd.]

the said segments are kept together, consisting of relying only on the screws that
attach same to the disc, on which they are placed, with the grain of the wood
end on, the screws entering in the direction of the run of the grain thereby
chiaining but a slight hold on the said segments.
Now my invention consists of forming at one end of said segments, a cavity,
groove or recess, and at the other end a ridge, projection or other raised portion,
so that when building up a ring or rim of segments so constructed the projec-
tions and grooves at the opposite ends thereof correspond to each other.
To enable my invention to be more clearly understood, I have hereunto
appended a sheet of drawings in which:-
Fig. 1 is a plan view of the polishing surface of a bevelled glass polishing
wheel shewing one form of constructing the said segments.
Fig. 2 is a similar view of same, shewing several forms which the said seg-
ments may take.
.
In bringing my invention into effect I construct the segments A of willow,
poplar or other suitable wood, having one end splayed as at a and the other end
recessed as at b, and with such shaped segments A I build up the annular ring
as shewn by Fig. 1 ready for fastening to the disc which forms the base of the
bevelled glass polishing wheel.
Or I may adopt any of the forms of constructing the ends of the segments as
shewn in Fig. 2, such as a square ploughed end c with a like tongue d, or con-
struct the ends so as to form a dovetail connection as at e, or with one end hol-
lowed out and the other end finished off with a curved projecting portion to fit
thereinto as shewn at f, or construct the ends with a tapered tongue g, and like
groove h, or I may adopt the form shewn at i, where the ends are only partly
splayed and recessed; from which it will be understood that a wheel rim or ring
constructed of segments as shewn and described will be more capable of resisting
any force tending to pull them apart or displace them in any way.
Although I have not illustrated my invention in connection with vehicle or
other wheels in which the rim or periphery is built up of segments, it will be
seen that it is equally applicable thereto, as it is to the wheel shewn in the
appended drawings.
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
First. In an improved manner of constructing bevelled glass polishing wheels,
the construction and use of the segments A connected together as herein
described and shewn by Fig. 1 of the accompanying drawings.
Second. In an improved manner of constructing bevelled glass polishing
wheels, the construction and use of the different forms of segments A as herein
described and shewn by Fig. 2 of the accompanying drawings.
'
Third. In an improved manner of constructing the rim or periphery of vehicle
or other wheels, in which the same is built up of segments, the construction and
use therefor, of the different forms of segments herein described and shewn in
the appended drawings.
