PROVISIONAL SPECIFICATIUN,
Improvements in and relating to Acetylene Gas Lamps for Cycles or
other analogous use.
We, HENRY STEARNS, of 68, Wilmslow Road, Rusholme, Manchester, in the
County of Lancaster, Cycle Manufacturer, and SAM WILSON, of 119, Wilmslow
Road, Rusholme, aforesaid, Plumber, do hereby declare the nature of this inven-
tion to be as follows:-
Our invention relates to improvements in and relating to acetylene gas lamps
for bi- try- or other cycles also for carriage or other analogous use.
The objects of our invention are 1stly to provide a lamp in which the water may.
be allowed to pass in regular or definite quantities to the carbide chamber by
which means gas may be steadily formed and a steady light produced at the
burner 2ndly to provide an arrangement in connection with the burner whereby the
thoroughfare may always be maintained open so as to allow of the free emission of
gas as generated. It is well known that in acetylene lamps now generally used
the water is allowed to pass to the carbide chamber in irregular quantities whereby
gas is irregularly generated consequently affecting the light or flame at the
burner also when the light is turned out or the gas supply stopped a hard
deposit is formed at the burner thus obstructing the thoroughfare and requires
opening for which purpose a needle is provided for opening the thoroughfare
which is oftentimes a difficult operation, e.g. on a dark night. According to our
construction we employ in the water supply chamber a spindle which at the
lower part of the chamber passes through an opening-the construction of which
and the carbide or chemical containing chamber hereafter mentioned is well-
known. The spindle at such part is of conical section, the said spindle is provided
at the upper part of the chamber with a small toothed wheel or pinion which
works into a toothed rack forming part of the spindle, the pinion is carried by a
spindle which extends to the outside of the chamber and terminates with a knob.
In connection with the usual hollow stem or burner extending from the
chemical chamber we provide a piece of wire which passes through the hollow
stem which wire is connected with a screw-threaded piece capable of being turned
by the fingers and supported in the side of the chemical chamber which screw-
threaded piece accordingly as it is turned, i.e. to screw into or out of the burner-
in the former case the wire is pushed through and may extend out of the burner
in the latter is pulled out of the burner thus allowing the gas to pass through the
burner thus any deposit may be removed from the top of the burner. When the
spindle in the water chamber actuated so as to allow water to pass therefrom
the conical form of the spindle admits only of the passing of certain or definite
quantities of water to the chemical chamber which may be admitted gradually
more or less according to the size of the section of the spindle.

We, HENRY STEARNS, of 68, Wilmslow Road, Rusholme, Manchester, in the
County of Lancaster, Cycle Manufacturer, and SAM WILSON, of 119, Wilmslow
Road, Rusholme, aforesaid, Plumber, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:—
The objects of our invention are Firstly to provide a lamp in which the water
may be allowed to pass in regular or defined quantities to the carbide chamber, by
which means gas may be regularly generated and a regular emission thereof
at the burner, thus when the gas is ignited, a steady light may be produced at
the burner, Secondly, to provide an arrangement in connection with the burner,
whereby the thoroughfare may always be maintained open, so as to allow of the
free exit of gas as generated. It is well known that in acetylene gas lamps as
now generally used the water is allowed to pass to the carbide .or. chemical
chamber in irregular quantities, whereby gas is irregularly generated, consequently
affecting the light or flame at the burner, also when the gas is turned off, a
deposit of hard matter is formed at the burner, which obstructs the thorough-
fare, a pricker or instrument is usually employed externally, for the purpose of
removing the deposit, this operation is often difficult, having to be performed
under difficult circumstances, such as trimming the lamp at night time.
In order that our invention may be clearly comprehended we have hereunto
annexed a sheet of drawings illustrating our invention like letters of reference
indicating like parts.
Figure 1 is an elevation of a cycle lamp part in section in order to shew the
application of our invention thereto.
Figure 2 is a plan shewing the upper part of Figure 1, that is, the pinion
and spindle in the water chamber.
Figure 3, is a detail shewing the burner detached from the lamp.
The
According to our invention we employ in the water chamber a a spindle b which
passes through a tube or thoroughfare c situate at the lower part of the water
chamber a into or terminates with the carbide or chemical chamber d the con-
struction or arrangement of which chambers a and d are well known.
spindle is also provided at its upper part with a toothed piece or rack f which
is held in position by means of a fixed guide piece g fixed at the inside of the water
chamber see Figure 2. The said rack piece f engages with a correspondingly
toothed pinion wheel h which is supported by a spindle i provided with a knob or
turning piece j.
We provide the knob with a stop piece va stop piece v is also provided on the
side of the lamp case or body so that when spindle i is turned the stop piece v may
come in contact with v and limit the rotation of spindle i consequently the lift
of valve e.
In connection with the usual hollow stem piece k which extends from the
chemical chamber d is provided a burner which may be of any ordinary
construction.
Within the said stem k we employ a wire piece or pricker which passes
through the thoroughfare of the stem to or near the outer or upper extremity
of the burner which may be an ordinary burner, and is suitably connected at its
other end to a screw threaded pieces by means of a connecting piece or spindle t
which piece when the screws is suitably turned travels towards the stem k and
covers or closes the entrance of the thoroughfare in the stem and situate within

page_text: the carbide chamber when this operation occurs the wire piece o is consequently
pushed forward and the end o¹ is caused to pass through or out of the burner to a
position which may be a position as shewn in Figure 3, thus accordingly as the
screw threaded piece is turned in direction to the right, or to the left hand the
wire o may be pushed through or withdrawn from the burner 1, thus any deposit
which may be situate over the orifice at the outside of the burner may be removed
and a free admission of gas is allowed to pass through the same, the removal
of which is an important object to be attained by this our invention.
When the spindle b is actuated or the conical piece e raised as shewn in dotted
lines Figure 1 so as to admit water to the chamber d, the conical form of the
piece e allows more or less in quantity to pass through the thoroughfare c accord-
ing to the section of the said piece e which may be presented to the entrance of
the said thoroughfare the water may then pass by capillary attraction down the
spindle band pass off at its extremity to or come in contact with the chemical
compound in the chamber d. The stop pieces and ¹ prevent the piece e from
being lifted too high from its seat at the entrance to tube c so as to allow only of
defined quantities of water to pass to chamber d.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In combination the rack or other suitably actuated spindle thoroughfare c
conically shaped piece e screw actuated wire o and burner as and for the purposes
herein fully set forth and described in the annexed drawings.
2. In combination the conically shaped-piece e and thoroughfare c as and for the
purposes herein set forth.
l
3. In combination the screw actuated wire o stem k and burner as and for the
purposes herein set forth.
4. The wire or pricker o actuated by a screw or other equivalent for the
purposes herein set forth.
