Year: 1888

page_text: the nature of this invention to be as follows :—
My improved appliance consists in a portable and convenient instrument for adjusting
and controlling the height of a gas jet, and is especially applicable in connection with
the melting of sealing-wax or similar substance usually employed in fastening or
securing small parcels, letters, capsules, and paper or parchment documents generally;
and further for the lighting of cigars tobacco pipes &c. &c.
My improvements are also applicable to the regulation of a burning gas jet at a
distance.
Briefly described I carry out my invention by mounting on a small table or stand
a metal pillar, the bulb or head of which forms a socket. This socket is furnished with
a plug, which works in the said socket in such a manner as to constitute an ordinary
tap. Gas is conducted to this socket by means of a pipe or connection which is
screwed into one of its sides, or if found desirable, this connection may be made a part
and portion of the socket itself, its sole use being to carry a flexible or rigid pipe for
conveying the gas. At the opposite side of the socket a hole is drilled and tapped to
receive the burner for melting the wax, or if desirable a Bunsen Burner may be
attached for dental purposes. The socket also carries a pipe attachment for supplying
a light to the operator when such may be required.
In the case of the burner for melting wax which is a straight jet burner, I
prefer to shield or surround it with a metal casing or cylinder, in such a manner
that however small the burning jet may be it is not liable to be blown out by a
draught.
The shank or arm of the plug which enters the socket is not extended or supported
by separate brackets or shielded as in my previous improvements dated 24th day of
August 1887 and numbered 11505, but I simply attach a lever thereto projecting
sufficiently far for the arm of the operator to rest upon.

page_text: By means of a moveable or sliding spring which works on the socket and
which impinges on the said lever, any pressure that the operator may exert on the
lever is returned by the spring, in such a manner that the operator can control the
height of the gas at will without in any way interfering with the work which he may
have in hand.
In regard to my invention for regulating a burning gas jet at a distance, I simply
propose to operate it by means of a cord, attached to the lever and which after passing
over a pulley fixed on the base of the instrument is conducted to any distant point
that the operator may desire.

page_text: I JAMES DOCTOR COCKER of 159 Butler Street Manchester, Chemist do hereby
declare the nature of my said invention to be as follows :-
My improved appliance consists in a portable and convenient instrument for
adjusting and controlling the height of a gas jot and is especially applicable in
connection with the melting of sealing wax or similar substance usually employed in
fastening or securing small parcels, letters, capsules and paper or parchment
documents generally and further for the lighting of cigars, tobacco pipes etc. etc.
My improvements are also applicable to the regulation of a burning Gas Jet at a
distance.
And in order that this my said invention may be the more readily understood and
carried into practical effect I have hereunto annexed drawings illustrative of my
improved apparatus and will now proceed to describe the same with the assistance of
the various Figures and letters of reference marked thereon.
Fig. 1 is a front view of my improved gas regulating apparatus and Fig. 2 is a side
view of the same. In both the previous views the apparatus is illustrated with the
regulator closed so as to reduce the gas jet to the smallest limits. Fig. 3. represents a
side view and Fig. 4 a plan view (partially in section) of the same apparatus but
shewing the regulator open and the gas jet increased in proportion. Figs. 5. and 6.
represent a sectional view of the regulating plug in the open and closed positions. In
all the views the same letters of reference are used to denote similar parts.
In performing my invention I mount upon a wooden or other suitable base a a
inetal pillar or standard 6 from the top of which rises an ordinary gas burner c
controlled by the usual gas tap d. This gas burner c is designed for illuminating
purposes and is not controlled by my improved regulator-near the upper part of the
pillar is a tail-piece e for providing a connection with a gas supply say by means of
a flexible or rigid connecting pipe and on the other side of the pillar and immediately
opposite to the tail-pipe e is a globular shield or casing f containing in the centre a
small rat tail gas burner or orifice g as seen more clearly in Figs. 1. and 4. This
shield is designed to afford to the gas jet when turned low complete immunity from
the effect of draughts of wind etc. My improved regulator consists of a tapered plug /
ground into a suitable socket formed in the pillar and so constituting a plug cock.
This plug h contains a pair of orifices see Figs. 5. and 6. one of larger area m to
supply the full sized flame and the other n only sufficiently large to allow gas to pass
to support the smaller flame.
This plug is operated by a cranked lever i affixed upon its front extremity and the
shorter arm of such lever is connected to one end of a long spiral spring j rising from
the base the constant tendency of this spring being to draw the lever i down so as to
rest upon the adjustable bracket k as seen in Fig. 2. In this position of the parts (and
which corresponds with the position of the plug in Fig. 6) the gas jet is turned down
and when required to be increased in volume say for melting sealing wax or for

page_text: any analogous purpose it is only necessary for the operator to rest his hand or
arm upon the plate branching from the lever i when the plug turning partially
upon its axis permits more gas to flow and the spring; becoming meanwhile distended
to the position indicated in Fig. 3. so remains ready to draw back the plug
automatically to its original position immediately the weight or pressure of the
operator's hand is removed. The projection p upon the small arm of the lever i
serves by coming in contact with the pillar to prevent the plug turning too far.
Instead of a rat tail burner it will be obvious that a Bunsen burner may be
substituted for dental purposes.
In regard to applying my invention to the purpose of regulating a burning gas jet
at a distance I simply propose to operate it by means of a cord attached to the lever
and which after passing round a pulley fixed on the base of the instrument is thence
conducted to any distant point that the operator may desire.
Having thus particularly described and ascertained the nature of this my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. The improved arrangement and combination of parts constituting a gas
regulating appliance substantially as and for the purposes hereinbefore described and
illustrated on the accompanying drawing.
2nd. In a gas regulating appliance the employment of a lever arm for operating the
plug of the cock in conjunction with a spiral spring for automatically operating the
plug when released substantially as and for the purpose hereinbefore described and
illustrated on the accompanying drawing.
3rd. In a gas regulating appliance the employment of a shield or casing for
enclosing and protecting the reduced gas jet substantially as and for the purposes
hereinbefore described and illustrated on the accompanying drawing.
