Improvements in Valves for Pneumatic Tyres, Saddles, and Cushions,
also for Roller Skates and other Articles Requiring Inflation.
I, BERTRAM JAMES SWAN, of 49, Holly Street, Dalston, in the County of
London, Commercial Clerk, do hereby declare the nature of this invention to be
as follows: -
My invention relates to valves of the type described in the Specification of the
Patent No. 1683293, and is designed for use with pneumatic tyres, saddles, and
cushions, also with roller skates and other appliances, or apparatus, which it is
required to inflate. It has for its object to so construct such a valve as to render
it easy of ready repair, cleaning, or inspection without having to remove it
bodily from the tyre (or other appliance or apparatus) or to detach it therefrom,
as is now the case with a valve of this type which is very inconvenient and often
very difficult.
To this end, I construct my valve in such a manner that a part of it can be
readily detached, without having to remove it in its entirety, and so permit of
prompt access to the internal parts for any purpose.
or
A convenient arrangement consists in forming the body, casing, or valve box;
in two (or more) parts, one of which is provided with an externally screw-
threaded portion whilst the other part has an internally screw-threaded
or tapped portion, so that these two parts can be rapidly attached,
detached, the arrangement being such that when the parts are unscrewed the
interior of the valve box can, at once, be got at for the required purpose. Or I
may so construct these parts that they can be held tightly together by frictional
contact, or otherwise.
In this way, it will be obvious that it will be unnecessary to remove the entire
device, should it be required to repair, clean, or inspect the valve proper, or any
of the interior parts of the valve casing.

N.E., do hereby declare the nature of this invention and in what manner the

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My invention relates to valves of the type described in the Specification of the
Patent No. 16832/93, and is designed for use with pneumatic tyres, saddles and
cushions, also with roller skates and other appliances or apparatus which it is
required to inflate. It has for its object to so construct such a valve as to render
it easy of ready repair, cleaning, or inspection, without having to remove it
bodily from the tyre (or other appliance or apparatus) or to detach it therefrom,
as is now the case with a valve of this type, which is very inconvenient and often
very difficult.
To this end, I construct my valve in such a manner that a part of it can be
readily detached without having to remove it, in its entirety, and so permit of
prompt access to the internal parts for any purpose.
or
A convenient arrangement consists in forming the body casing, or valve box.
in two (or more) parts, one of which is provided with an externally screw-
threaded portion whilst the other part has an internally screw threaded
or tapped portion, so that these two parts can be rapidly attached
detached, the arrangement being such that when the parts are unscrewed, the
interior of the valve box can at once be got at for the required purpose. Or I
may so construct these parts that they can be held tightly together by fictional
contact, or otherwise.
In this way it will be obvious that it will be unnecessary to remove the entire
device should it be required to repair, clean, or inspect the valve proper, or any
of the interior parts of the valve casing.
The accompanying drawings show the parts of my valve as follows:-Figure (1)
shows the outside view of the complete valve. Figure (2) is the main valve
box. Figure (3) is a plug with spring attached, the said plug being made of
india rubber or other suitable material for effectually closing into the cone seat E
which is shown at the lower or engaging end of Figure 4. To fit my valve the spring
& plug Figure 3 are dropped into the valve box Figure 2 the rubber plug being
uppermost or nearer the end of the valve or valve box which the screw plug
Figure 4 is to be screwed into. I then take the screw plug Figure 4 & screw the
same into the valve box Figure 2 so that the cone seat E presses on the rubber
plug Figure 3, then when air is pumped through the valve a pressure of the air
will force the plug Figure 3 backwards allowing the air to escape round it, &
when the outside pressure of air is taken off the pressure from the inside of the
tyre or other article to be inflated will drive the plug into the cone causing &
making a perfectly air tight joint.
Having now particularly described & ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
A combination of the spring plug & cone with the cone seat part detachable
from the valve substantially as set forth.
