ves for inflating and deflating air tubes, bladders other receptacles
Year: 1898

page_text: I, ANGUS PATERSON, of 24, Shaftesbury Cottages, Gordon Park, Whiteinch, in
the County of Lanark, North Britain, Cashier, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in valves for inflating and deflating air
tubes, bladders, or other receptacles.
The invention consists of a small hollow chamber having an opening right
through the centre and with a recess on the outer face of the inside wall for
the valve seat to rest in, the spindle projecting slightly through on the opposite
side. Small perforations are provided on the recessed portion for the purpose
to be hereafter described, and over the outside of the inner face of the chamber
there is a thin sheet of india-rubber or other elastic material, the ends of which
are placed into a small groove round the rim of the chamber and tightly tied,
the outer edges being perforated. On the valve spindle there is a small thumb-
screw for operating the valve seat.
On inflating an air tube, the inflator is inserted into a small opening on the
outer face or wall of the chamber provided for the purpose, and the air is ferced
into the hollow of the chamber when it finds its way through the perforations
in the recessed portion, and passes under the thin sheet of india-rubber and out
of the perforations in it into the air tube. When the tube has been inflated
the back pressure of the air on the rubber closes it down against the valve seat
and so prevents any air from escaping.
In deflating, the thumb-screw is simply turned, when the valve is lifted off its
seat and the air allowed to escape in the same way as it entered.
In place of having the small opening in the outside wall of chamber for the
admission of the air, I might have the valve spindle with an opening through
the centre and an outlet into the hollow chamber at the inner end.
Dated this 22nd day of February 1898..

page_text: this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:-
My invention relates to improvements in valves for inflating and deflating air
tubes, bladders, or other receptacles.
In order that my invention may be properly understood and readily carried
into effect I have hereunto appended one sheet of drawings, the several figures
of which are marked with the same letters of reference.
Figure 1 is an elevation of the inside of one form of valve.
Figure 2 is a longitudinal section of Figure 1.
Figures 3 and 4 are similar views of a different form of valve.
The invention consists of a small hollow chamber having an opening B
right through the centre and with a recess C on the outer face of the inside wall
for the valve seat D to rest in, the spindle F projecting slightly through on the
opposite side. Over the recess C there is a washer W. Small perforations G
are provided on the recessed portion C for the purpose to be hereafter described,
and over the outside of the inner face of the chamber there is a thin sheet of
india-rubber H or other elastic material, the ends of which are placed into a
small groove I round the rim of the chamber and tightly tied, the outer edges
being perforated. On the valve spindle there is a small thumb-screw J for
operating the valve S see Figure 3.
In place of operating the valve by a thumb-screw it may be operated by the
nut shaped end F of the spindle F as shewn in Figure 2, or by the outer face L
of the chamber A as shewn in Figure 4.
On inflating an air tube, the inflator M is inserted into a small opening N on
the outer face or wall of the chamber provided for the purpose, and the air is
forced into the hollow A of the chamber A, when it finds its way through the
perforations G in the recessed portion C, and passes under the thin sheet of india-
rubber H and out of the perforations Q in it into the air tube. When the tube
has been inflated the back pressure of the air on the rubber closes it down
against the valve seat and so prevents any air from escaping.
In deflating, the thumb-screw, spindle, or outer wall as the case may be is
simply turned, and the spindle pressed inwards when the valve with washer is
lifted off its seat and the air allowed to escape in the same way as it entered.
In place of having the small opening N in the outside wall L of chamber A
for the admission of the air, as seen in Figures 1, 2, and 4, might have the
valve spindle with an opening N1 through the centre and an outlet S into the
hollow chamber at the inner end.
Suitable covers T are provided for the openings for the inflator.
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:-
Valves for inflating and deflating air tubes, bladders, or other receptacles,
constructed substantially as described and illustrated on the accompanying sheet
of drawings.
