Improvements in Apparatus for Inflating Pneumatic Tyres.
I, EMILE LEHRNER, of 31, Place de l'Hotel de Ville, St. Quentin, in the
Republic of France, Engineer, do hereby declare the nature of this invention
to be as follows:-
The appliance which forms the subject of this invention is intended for the
inflation of pneumatic tyres of vehicles of any kind without the aid of a compres-
sion pump. The appliance consists of a bottle or other vessel containing highly
compressed air acting in combination with a pressure reducer enabling the pres-
sure in the tyres to be regulated exactly to the desired degree without any care
being necessary on the part of the operator. This appliance, which may be made
in all sizes, replaces the customary pump, as compared with which it possesses
the following advantages.
1. It effects the inflation more rapidly and without any effort on the part of
the operator; in fact it is only necessary to join, in the usual way, the inflating
valve of the tyre to a flexible tube which is provided with the pressure reducer,
and to open the cock or valve of this latter for the inflation to be instantaneously
effected so to speak.
2. The operation of inflation is certain and invariably produces the same de-
gree of compression; this advantage is obtained owing to the pressure reducer
which is so regulated as to cause in the tyres the pressure which is considered
most suitable.
The improved apparatus comprises a bottle or other vessel of variable form and
dimensions and made of a metal which is sufficiently strong within which air
is highly compressed in the usual way. This vessel is provided with a head fur-
nished with any suitable closing device, for example a cock which when closed,
enables the vessel to be moved from place to place. This head has a screw
threaded portion in which is fixed, by means of a union the connections of a
pressure reducer of any suitable kind. This reducer is provided with a valve by
means of which it is operated when connection has been made and the cock
opened, a screw or other equivalent part acting upon the operative parts of the
said reducer, and enabling the reduction of pressure to be regulated at will, and
with an outlet tube upon which is fixed a flexible tube enabling the apparatus to
be connected in the ordinary manner to the valve of the tyres to be inflated.
From the preceding description it will be readily understood that the vessel
alone. having been suitably, charged with compressed air, may be supplied, in
the same way as vessels containing oxygen, carbonic acid and so forth to estab-
lishments of all kinds such as hotels, racing tracks and the like, where the
pressure reducer may be added. When this latter has been attached, the cock
is opened in such a manner as to place the vessel in direct communication with
the reducer. The regulation' of the reducer is then effected, and when this latter
is connected with a tyre by means of the flexible tube it is only necessary to open

page_text: the valve in order that the tyre may be instantaneously inflated to the pressure
for which the reducer is adjusted.
It is thus apparent that the necessity for feeling or testing the tyre during
inflation is obviated, and accidents resulting from forcing in too great a quantity
of air need no longer be feared. In practice the vessel may contain the air
necessary for inflating 150 to 250 tyres. Renewal vessels may be provided.
Upon the same principle appliances adapted for effecting from 5 to 10 inflations
may be constructed. These appliances may be advantageously employed by
cyclists and by the owners of autocars, tricycles or other light petroleum vehicles.

Improvements in Apparatus for Inflating Pneumatic Tyres.
I, EMILE LERNER, of 31, Place de l'Hotel de Ville, St. Quentin, 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 statement:——
The appliance which forms the subject of this invention is intended for the
inflation of pneumatic tyres of vehicles of any kind without the aid of a compres-
sion pump.
The appliance consists of a bottle or other vessel containing highly compressed
air acting in combination with a pressure reducer enabling the pressure in the
tyres to be regulated exactly to the desired degree without any care being neces-
sary on the part of the operator.
This appliance, which may be made of any size is designed to replace the cus-
...tomary pump, as compared with which it possesses the following advantages:
(1) It effects the inflation more rapidly and without any effort on the part of
the operator; in fact it is only necessary to connect, in the usual way, the inflating
valve of the tyre to a flexible tube which is provided with the pressure reducer,
and to open the cock or valve of this latter for the inflation to be instantaneously
effected, so to speak.
(2) The operation of inflation is certain and invariably produces the same de-
gree of compression; this advantage is obtained owing to the pressure reducer
which is so regulated as to produce in the tyres the pressure which is considered
most suitable.
In order that my improved inflation appliance may be readily and clearly
understood I have represented a constructional form of the same in the accom-
panying drawing, to which I will now refer.
In this drawing A is a bottle or other vessel of variable form and dimensions
and made of a metal which is sufficiently strong, within which air is highly 'com-
pressed in the usual way. This vessel is provided with a head a furnished with
any suitable closing device, for example a cock b which, when closed, enables the
.vessel to be moved from place to place. This head a has a screw threaded portion
in which is fixed, by means of a union c, the connection of a pressure reducer B
of any suitable kind. This reducer is provided with a valve d by means of
which it is operated when connection has been made and the cock b opened, a
screw or other equivalent part acting upon the operative parts of the said reducer

page_text: and enabling the reduction of pressure to be regulated at will, and with an outlet
tube e upon which is fixed a flexible tube C enabling the apparatus to be con-
nected, in the ordinary manner to the valve of the tyres to be inflated.
From the preceding description it will be readily understood that the vessel
alone, having been suitably charged with compressed air, may be supplied, in
the same way as vessels containing oxygen, carbonic acid and so forth to estab-
lishments of all kinds such as hotels, racing tracks and the like, where the
pressure reducer B may be added. When this latter has been attached, the cock b
is opened in such a manner as to place the vessel a in direct communication with
the reducer B. The regulation of the reducer is then effected, and, when this
latter is connected with a tyre by means of the flexible tube C, it is only necessary
to open the valve d in order that the tyre may be instantaneously inflated to the
pressure for which the reducer is adjusted.
It is thus apparent that the necessity for feeling or testing the tyre during
inflation is obviated, and accidents resulting from forcing in too great a quantity
of air need no longer be feared. In practice the vessel A may contain the air
necessary for inflating 150 to 250 tyres. Renewal vessels may be provided.
Upon the same principle appliances adapted for effecting from 5 to 10 inflations
may be constructed.
These appliances may be advantageously employed by cyclists and by the
owners of auto-cars, tricycles or other light petroleum vehicles.
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. An appliance for the inflation of the pneumatic tyres of vehicles of every
description, characterised as a whole by the combination of a vessel containing
highly compressed air with a pressure reducer intended to cause the air to pass.
rom the said vessel into the pneumatic tyre at a pre-determined pressure.
2. The inflating appliance as above described as a whole and in detail, with
eference to the accompanying drawing.
