Improvements in Handles for Valves and similar Appliances.
We JOHN BREARLY HEIGHINGTON of 327 Euclid Avenue in the City of Toronto in
the County of York in the Province of Ontario in the Dominion of Canada and
WILLIAM HEIGHINGTON of 387 Manning Avenue in the said City of Toronto, Pattern
Makers do hereby declare the nature of this invention and in what manner the
saine is to be performed to be particularly described and ascertained in and by the
following statement :-
'
The object of the invention is to make a strong, and cheaply constructed handle for
valves tallow cups steáin guages and all similar appliances that will act as a non-
conductor of heat and cold, and it consists essentially in making the disc web or plate
of metal having a flanged edge which is encased in a removeable annular ring of
rubber or other suitable non-conducting, material, having a channel or groove formed
to correspond with the flanged edge of the disc.
To prevent the rubber ring from slipping around the periphery of the disc when
a greater force than usual is required to turn the handle, we corrugate the periphery
of the disc and the channel of the rubbering and the corrugations meshing, both the
ring and the disc are obliged to move simultaneously.
And in order that the said invention may be more clearly understood and readily
carried into effect we will proceed aided by the accompanying drawings more fully to
describe the same.
Sectional view showing the arrangement and construction of the
rubber ring and disc.
Figure 3. is a plan view of the disc.
Figure 4. is an elevation of the disc.
Figure 5. is a section of the rubber ring.
Like letters of reference refer to like parts throughout the specification and drawings.
A is our improved handle for valves, tallow cups, steam guages, and all similar
appliances consisting of metallic disc B having a corrugated flanged edge b which
is encased in annular ring C of rubber or other suitable non-conducting material.
This ring C has a corrugated groove or channel c formed to correspond with the
flanged edge of the disc B.
The object of this corrugated flanged edge b and corrugated groove c is to prevent
the ring slipping around the periphery of, or being separated from the disc B when
a greater force than usual is applied to turn the handle.
The Ting is removeable from the disc B so that if the rubber is burnt it can be
removed and replaced by another without removing the handle A from the
valve stem.
It will be noticed that the nut D on the upper face of the disc B is slightly below
the level of the top of the ring C it being arranged thus, so that when the handle is
taken hold of the hand runs no risk of being burned by coming into contact with any
portion of the metal forming part of the handle A which is heated to a temperature
proportionate to the length of the stem and the temperature of the valve.
It will be seen from the foregoing description that the ring C composed of
rubber or other suitable material that is a non-conductor of heat and is always at
mean temperature of about 55° Fahrenheit, forms the grip and is the only thing
that the hand comes in contact with,

page_text: Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In a handle for valves tallow cups, steam guages and similar appliances the
combination of the metallic disc B having a flanged edge with the annular ring C
of rubber or other suitable non-conducting material having a channel c formed to fit
the flanged edge of the disc B substantially as and for the purpose set forth.
2. In a handle for valves, tallow cups steam guages and similar appliances the
combination of the metallic disc B having corrugated flanged edge b with the annular
ring of rubber or other suitable non-conducting material having a corrugated
channel c formed to fit the corrugated flanged edge of the disc B substantially as
and for the purpose set forth.
