IMPROVEMENTS IN LAMPS FOR BURNING BENZOLINE & SIMILAR HYDRO-CARBONS
Year: 1884

page_text: I THOMAS WOOD, of Blindley Heath Post Office, in the Parish of Godstone,
County of Surrey, Grocer, and Draper, do hereby declare the nature of my
invention for "IMPROVEMENTS IN LAMPS FOR BURNING BENZOLINE & SIMILAR
HYDRO-CARBONS," to be as follows:-
A portable lamp made in Metal, Earthenware, China, or Glass to burn the usual
hydro-carbon Spirit, such as Benzoline, Gasoline Camphine, Napthaline &c and
which improvements shortly described below, are conducive to their greater safety,
economy, and use, The same arrangement is also applicable as a fixed lamp, and
will with much less trouble, give a light equal to coal gas, and be of much
advantage to the general public.
Claim 1. To attain the ends of improvement with respect, to the "Wood Gas-
maker lamp," The neck of the reservoir must be made with a ledge or shoulder, E,
at the top of the screw inside, 8. a washer of leather or other elastic substance,
must be made to fit the screw of the burner tube.
Or, (in preference) the flange of the burner screw can be made with a channel,
so as to allow the neck of the reservoir to slide or screw within, and firmly render
the neck perfectly air-tight at the screw, 4. using the aforesaid washer.
6. An air chamber is attached to the burner tube, to prevent the flooding of
[the wick, by the liquid, which chamber greatly increases the portability of the
lamp.
The air chamber is closed to the burner tube at the upper part.
Protection is also requested with respect to the arrangement of the conducting
wick, which is very tightly compressed into the burner tube, to just below the
charring point of the cotton or wick, and from there it is met by a smaller tube
and wick to supply the burner proper. The small tube 3. may fit the burner tube
either loosely or tightly at the junction of the cap, if a loose tube is used, the
wick drawn through must be returned back evenly to exclude the air. No 1.
Carbon heater.
Or to attain the same end, cotton, asbestos, or other conductive material may
be used, instead of the small tube, these if used must fit loosely, and reach No 1,
Carbon heater.
With respect to the fixed lamps in which the air chamber is Optional, it is
claimed to supply them with liquid in solid drawn tubing of the smallest
convenient size, so that the bulk of the liquid may be at any convenient distance
from the light. (7).

page_text: I, THOMAS WOOD, Grocer & Draper of Blindley Heath, Godstone, Surrey, do
hereby declare the nature of my invention for IMPROVEMENTS IN LAMPS FOR
BURNING BENZOLINE AND SIMILAR HYDROCARBONS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:-
The Improvements in Lamps (Portable or Fixed) for burning Benzoline, and
similar hydrocarbons andI called, the "Wood gas-maker Lamp" is fully described
herein, and to be shortly as follows:-
1st An airtight, neck at the Screw of burner, in connection with compressed wick
secures a safe lamp.
1
2ndly Ecconomy, of wick, time, & trouble, by use of small tube, at burner cap.
3rdly Prevention of flooding wick by use of air chamber.
4thly Small size solid tube for supply.
The lamp called the "Wood Gas-maker Lamp" may be made in Metal, China,
Glass, or Earthenware.
'
The improvements are described below, and are conducive to their greater
safty, economy, and use, and of much advantage to the general public.
The neck of the reservoir, A. must be made with a ledge, or shoulder, at the top
of screw inside, a washer of leather, or other elastic substance must be made
to fit the shoulder, and to run on the screw of the burner tube.
Or, (in preference,) the .B. flange of the burner screw can be made with a
channel, so as to allow the neck of reservoir to slide or screw within, and firmly
render the neck perfectly airtight at the screw, using the aforesaid washer.
An air chamber. D. of convenient size is attached to the burner tube, or flange,
to prevent the flooding of the wick by the liquid, which chamber greatly increases
the portability of the lamp.
The air chamber is closed to the burner tube, or to the flange, at the top of
chamber.
1
Protection is also requested with respect to the arrangements of the conducting
wick which is very tightly compressed in the burner tube, to just below the
charring point of the Cotton or wick, and from there it is met by a smaller tube,
and wick, to supply the burner proper. E. The smaller tube may fit the burner
tube, either loosely or tightly at the junction of the cap, if a loose tube is used
the wick drawn through must be returned back evenly to exclude the air. 2. Or
to attain the same end (but not so well,) cotton, asbestos, or other conductive
material, may be used instead of the small tube, these if used must fit loosely.
With respect to fixed lamps. F. in which the air chamber is optional, it is claimed
to supply them with liquid, in solid drawn tubing of the smallest convenient size.
G. so that the bulk of the liquid may be at any safe distance from the light. The
size also of the fixed lamps with supply tube, can be greatly reduced.
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
tats
Firstly, The shouldered neck, and leather washer, to render the same airtight.
Secondly, The Channelled Flange, with leather for, same end...
Thirdly, An air chamber, to prevent the flooding of wick in carrying about.
Fourthly, The compressed wick, having its end at a distance from the burner cap,
in the manner and for the purposes substantially as hereinbefore described.

page_text: Fiftbly, The small tube at or near the burner cap, by which asbestos, cotton,
or other wick can be made to meet the conducting wick with great convenience.
Sixthly, The use of cotton, asbestos, or other conducting substances to meet the
long wick without the tube..
Seventhly, The arrangement of the reservoir on a much smaller scale similar
to the arm of a gas jet arranged to be constantly fed from without by solid
drawn tubing, in the manner and for the purpose substantially as herein before
described.

Inventor.
