PROVISIONAL SPECIFICATION.
Improvements in and connected with Inflation Valves.
I, JULES ALFRED BLOT, of 15, Boulevard Saint Denis, Paris, in the Republic
of France, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to render the inflation of articles 'quicker and
more reliable than heretofore has been the case.
The improved valve consists principally of two parts, one being secured to the
article to be inflated and the other to the pump or inflator.
The part secured to the said article consists of a tubular valve-body formed
externally on its entire length with a thread and about half way internally with a
seating upon which is adapted to operate a plug carried by the lower extremity of
a hollow spindle having two ports behind the said plug. The hollow spindle is
formed externally with a screw thread and is rendered adjustable in a gland screwed
on to the outer end of the valve body, a packing being inserted to form an air
tight joint between the same.
The part secured to the pump or inflator consists of another tubular valve
body having internally a conical valve operating upon a seating and a rim faced
with leather or the like. The respective end of the said valve body is internally
formed with a screw thread so as to facilitate it being screwed on to the first
named valve body, the said leather or other face forming a tight joint.
When it is desired to effect inflation the valve attached to the pump or
inflator is screwed on to the hollow spindle of the valve attached to the article to be
inflated and the hollow valve spindle screwed off its seating. The air from the
pump or inflator has then free access to the article to be inflated, the first named
valve acting as a back pressure valve during the time of inflation.
When the article is sufficiently inflated, the said hollow spindle is screwed down
upon its seat and the said back pressure valve with pump or inflator removed from
the said hollow spindle.

COMPLETE SPECIFICATION.
Improvements in and connected with Inflation Valves.
I, JULES ALFRED BLOT, of 15, Boulevard Saint-Denis, Paris, in the Republic
of France, Engineer, 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 statenient :-
This invention has for its object to render the inflation of articles quicker and
more reliable than heretofore has been the case.
The improved valve consists principally of two parts, one being secured to the
object to be inflated and the other to the pump or inflator.

page_text: And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a longitudinal section of the inflation valve open, below which is the
stop valve and joint for the pump, Fig. 2 is a longitudinal section of the stop
valve complete and closed. Fig. 3 is a similar view. of a modification of the
stop valve.
In carrying out my invention the part secured to the object to be inflated consists
of a tubular valve body A, formed externally on its entire length with a thread and
about half way internally with a seating upon which is adapted to operate a
plug H carried by the lower extremity of a hollow spindle C having two air ports J
formed crosswise behind the plug H. The hollow spindle C is formed externally
with a screw thread E and is rendered adjustable in a gland F screwed on to the
outer end of the valve body A, a packing G being inserted to form an air tight joint
between the same.
a
The part secured to the pump or inflator consists of another tubular valve body K
having internally a conical valve L operating upon a seat and a rim M having
conical part and below a leather or the like washer N. Through the rim M, its
cone and the leather washer N is formed a passage J1 adapted to admit air when
the valve L. leaves its seat. The corresponding end of the valve body K is
internally formed with a screw thread so as to facilitate it being screwed at D on
to the hollow spindle C, the leather or other washer N forming a tight joint
between K and C.
The part K containing the inflation valve L may be replaced by another union
containing a valve as is the case in other pumps.
The plug H may also be dispensed with, in which case a leather washer O is
placed upon the seating B, as shown in Fig. 3.
When the valve body Ċ descends on to the seating B the plug H enters the
passage of the seat B or the walls P press upon the washer O thus ensuring a
reliable cutting off of the air.
The washers N and G and plug H may be made of caoutchouc, leather, gutta-
percha, or the like, or of a semi-hard substance or vulcanized caoutchour, lead,
tin, and the like, the plug H I make preferably of a mixture of lead and tin.
When it is desired to effect inflation, the valve body K, attached to the pump or
inflator, is screwed on to the hollow part D of the spindle C arranged in the valve
body A attached to the object to be inflated and the hollow valve spindle C, D,
screwed off its seating B. The air from the pump or inflator raises the valve L off
its seat, passes round it, enters the passage.J and round the plug H the object to be
inflated, the valve L acting as a back pressure valve during the time of inflation.
When the object is sufficiently inflated, the said hollow spindle C is screwed
down upon its seat B and the said back pressure or inflation valve with pump or
inflator removed from the hollow spindle C, D.
.
The passage of the air is indicated in dotted lines.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is―
"In and connected with inflation valves."
1st. The general construction and combination of parts constituting my invention
operating substantially as set forth and for the purpose specified.
2nd. A hollow spindle longitudinally movable, the lower end of which is formed
with a cup adapted to receive a plug which embeds itself on a valve seat; in
combination two screw threads on the said spindle which when unscrewing the body
of the inflation valve permits of screwing down the stop valve, all substantially as
set forth.
3rd. A valve b. dy furnished internally with a valve operating during the inflation,
all substantially as set forth.

page_text: 4th. In lieu of caoutchouc valves, plugs of metal soft enough to form a perfect
and durable cut-off, all substantially as set forth.
