Improvements in Means employed in the Inflation of Pneumatic
Tyres.
1, VICTOR ERNEST GREMAUD, Gentleman of 42 Rue du Louvre, Paris, in the
Republic of France, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in means for inflating pneumatic tyres.
These means consist more particularly in the arrangement of a special form of
union by which the pump tube can be applied to any form of valve.
My invention relates also to a simplified arrangement of valve.
In order that my invention may be clearly understood I have shown in
the accompanying drawings an example of the principal arrangements which
characterize my invention.
Figure 1 is an exterior view of the pump connection tube with its union.
Figure 2 shows separately the clip for connecting the pump attachment to the
valve; in its open position.
Figure 3 is a side view of this clip.
Figure 4 is a transverse section of a pneumatic tyre and of the valve drawn to
an enlarged scale and
Figure 5 shows an exterior view of this same valve drawn to the same scale as
Figure 4.
In all the figures the same parts are indicated by similar letters of reference.
My system of clip is applied to the pump connection tube a one extremity of
which carries a screwed attachment to which the pump is screwed, the other
extremity of this tube a receives the clip formed of a flexible spring collar c the
two ends of which have lugs or projections e; these projections receive a tightening
screw. The screw f turns freely in one of the lugs by passing through an
elongated hole g, which allows of the opening of the collar.
The tightening of the clip thus constituted, is effected by the screwing of the
screw which causes the screw tapped lug in which the screw works to approach
the other lug having an elongated hole in it, which has for its object to allow of
the opening of the collar.
To prevent the introduction of the rubber tube between the two lugs of the clip
which would prevent the closing of this latter I have arranged in the interior of
the collar, a thin metallic tongue d fixed at one end only.
The tube a may have fixed around it rings a¹ between which the clip is placed
and which retain it in position.
This arrangement of clip allows of its adaptation to any kind of valve, but I
prefer to apply it to that kind of valve represented at Figures 4 and 5 having a
connecting tube smooth and not screwed on its exterior.
The valve is mounted on the air chamber i by means of the piece k surmounting
which carries the
a screw threaded tube within which is placed the rod g
valve r, and a washer m held applied against the outside of the air tube i by a
screw nut n.
The felloe or rim o is held between this screw nut n and a counter nut p.
The valve is constituted by a rubber or other suitable washer placed at the
end of the rod 9 and held by a nut s screwed upon this rod.
g
The rod 9 is simply screw threaded at its extremities to receive the nuts and a
dust proof capt at its base, closing the hole of the valve connection tube h, a

page_text: shoulder made on the rod q allows the play of the valve when the cap t is removed
and the pump connected to the valve connection tube h.
The dust proof cap t serves at the same time to assure the closing of the valve
connection tube so as to prevent the introduction of any particles of dust and above
all to draw the valve down on to its seat, so that any vibration during the running
of the machine will not subject the air chamber to become deflated; this cap may
be attached by a chain to a spoke of the wheel near the valve.

COMPLETE SPECIFICATION.
Improvements in Means employed in the Inflation of Pneumatic
Tyres.
I, VICTOR ERNEST GREMAUD, Gentleman, of 42 Rue du Louvre, Paris, in the
Republic of France, 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 means employed in inflating pneumatic
tyres.
These means consist more particularly in the arrangement of a special form of
union by which the pump inflation tube can be applied to any form of valve.
My invention relates also to a simplified arrangement of valve.
In order that my invention may be clearly understood, I have shown in the
drawings accompanying my Provisional Specification, an example of the principal
arrangements which characterize my invention.
Fig. 1 is an exterior view of the pump connection or inflation tube with its
union.
Fig. 2 shows separately the clip for connecting the pump attachment to the
valve in its open position.
Fig. 3 is a side view of this clip.
Fig. 4 is a transverse section of a pneumatic tyre and of the valve drawn to an
enlarged scale.
Fig. 5 shows an exterior view of this same valve drawn to the same scale as
Fig. 4.
In all the figures the same parts are indicated by similar letters of reference.
My system of clip is applied to the pump connection tube a, one extremity of
which carries a screwed attachment to which the pump is screwed; the other
extremity of this tube a receives the clip formed of a flexible spring collar c, the
two ends of which have lugs or projections e; these projections receive a tightening
screw f. The screw turns freely in one of the lugs by passing through an
elongated hole g which allows of the opening of the collar. The tightening of the
clip thus constructed is effected by the screwing of the screw which causes the
screw-tapped lug in which the screw works to approach the other lug which it
traverses by passing through an elongated hole, which has for its object to allow of
the opening of the collar.
To prevent the introduction of the rubber of the tube a between the two lugs of
the clip, which would present an obstacle to the closing or tightening of the
latter, I arrange in the interior of the collar, a thin metallic tongue & fixed at one
end only.
The tube a may have formed around it rings a¹ between which the clip is placed
and which retain it in position.

page_text: This arrangement of clip allows of its adaptation to any kind of valve, but I
prefer to apply it to that kind of valve, represented at Figs. 4 and 5, having a
connecting tube which is smooth and not screwed on its exterior.
The valve is mounted on the air chamber i by means of the piece or disc k
surmounting a screw-threaded tube h within which is placed the rod which carries
the valve r and a washer m held applied against the outside of the air tube i by a
screw nut n.
The felloe or rim o is held between this screw nut n and a counter nut p.
The valve is constructed of a rubber or other suitable washer placed at the
end of the rod g and held by a nuts screwed upon this rod. The rod q is simply
screw-threaded at its extremities to receive the nuts and a dust-proof cap t at its
base closing the hole of the valve connection tube h; a shoulder made on the rod
allows the play of the valve when the cap t is removed and the pump connected to
the valve connection tube h.

The dust-proof cap t serves at the same time to ensure the closing of the valve
connection tube, so as to prevent the introduction of any particles of dust, and
above all to draw the valve down on to its seat, so that any vibration during the
running of the machine will not subject the air chamber to become deflated; this
cap may be attached by a chain to a spoke of the wheel near the valve.
Having now particularly described and 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 :-
.
1. The arrangement of a flexible spring clip mounted on the extremity of the
inflating or connection tube of the pump by means of a screw which enables it to
be connected to various kinds of valve, substantially as herein shown and
described.
2. The simplified arrangement of the valve consisting in mounting the valve at
the extremity of a rod playing freely within the screw-threaded valve connection
tube connected with the valve seat and serving to fix it in position and terminated
by a cap which serves to close the aperture of the screw-threaded valve connection
tube and to hold the valve down to its seat so as to protect it against the effects of
vibration, substantially as herein shown and described.

page_text: two grooves i. cut around its circumference and adapted to work in the casing, K,
which I fix in any convenient position. To the said disc I fix a short spin.lle, j,
one end of which works in a bearing provided at the back of the said casing an
the other passes through the cover, L, of the same. To this spindle is fitted the
handle, k. I attach to one of the said grooves a pull, 1, of wire or other suitable
material which I connect to a sheave or grooved disc, M, attached to the spindle of
the discharge valve and which for convenience I pass under an intermediate
sheave, N, and to the other groove I fix a similar pull, ', which is connected to the
waste preventer plug, in such a manner that the two pulls move in opposite
directions.
Thus by turning the handle, k, the discharge valve, G, is opened simultaneously
with the flushing of the basin, and by releasing the sail handle, the said valve
immediately closes by reason of the balance weight, I, which ten is to keep it shut.
Provision is made to ventilate the discharge funnel by means of the pipe, O.
An overflow channel, Q, is also provided in the basin.
I connect the trap, B', to the soil pipe, P, by means of a union so constructed
that it enables the joint between the said trap and the said soil pipe to be more
readily and efficiently made or disconnected than by the means hitherto in use.
The upper part of this union shewn in section in Figure 1 and in plan in Figure 4,
I provide with a circumferential groove or depression, m, between which and the
exterior of the union I form communications by drilling holes, e, e, through the
flange thereof for the purposes hereinafter described. I also provide a raised or
projecting rim, o, adapted to fit loosely into the recess, p, of the lower part of the
said union, shewn in section in Figure 1, and in plan in Figure 5 thereby forming
an annular space around it.
In making the joint I proceed as follows. Having secured the upper part of the
union to the end of the trap, B', by means of suitable cement, I turn the lead soil
pipe over so as to form a flange to fit the recess, p, and I secure the said soil pipe
to the lower part of the union by means of a soldered joint. Upon the lead flange
I place a small quantity of putty or other suitable material whereon the projecting
rim, o, is bedded. The two parts of the union are now to be bolted together so
that the flanges thereof fit closely, and to complete the joint I introduce into one
of the holes, e, e, provided for the purpose, a sufficient quantity of melted hard
paraffin, or a mixture of hard and soft paratin, to all the circumferential groove, m,
and any other cavities that may exist between the upper and lower parts of the
union.
When it is desired to disconnect this union, I apply sufficient heat thereto to
melt the parathin when the parts can be withdrawn.
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 :-
I. A water closet having the basin provided with an outlet, C, opening towards
the front thereof, to which is fitted the discharge valve, G, in the manner
here.nbefore described and illustrated in the drawings.
II. A water closet having the basin provided with an outlet, C, opening
towards the front thereof, fitted with the discharge valve, G, and the discharge
funnel, B, having the op ning, D, to which is fitted the cover, E, substantially as
herein before described and illustrated in the drawings.
III. In a water closet, the combination of the trap, B', with the union, R,
constructed substantially as described and illustrated in the drawings.
IV. The combination of the grooved disc, J, and casing, K, Figures 3, 7 and 8,
with the discharge valve, G, as and for the purposes described and illustrated in
the drawings.
