Improvements in Paraffin Lamps.
I HENRY BAXTER of 9 York Lane in the City of Belfast and County of
Antrim in Ireland Plumber do hereby declare the nature of this invention to be as
follows:-
My invention relates to paraffin lamps of the type known as Hitchcock's Patent
and described in Specifications Nos. 3212 of 1873, 4283 of 1874 and 1102 of 1880
or other lamps in which a current of air is passed between the oil tank or receiver
and the outside case through the burner up to the flame and serves to maintain a
substantially impervious joint between the body or air fountain and cover of
such case.
For this purpose I attach to the side of the oil tank or receiver a number of
springs which press the rim of the body or air fountain against the rim of the cover
and keep the rims in close and continuous contact with each other.
By means of this arrangement where two or more lamps of similar size and
shape are in use the oil tanks or receivers may at any time be transferred, if desired,
from one to another case.
Dated this 12th day of February 1896.

Improvements in Paraffin Lamps.
I, HENRY BAXTER of 9 York Lane in the City of Belfast and County of
Antrim in Ireland Plumber, 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 paraffin lamps of the type known as Hitchcock's Patent
and described in the Specifications of British Patents Nos. 3212 of 1873
4283 of 1874 and 1102 of 1880 or other lamp in which a current of air is passed
between the oil tank or receiver and the outside case through the burner up to the
flame and serves to maintain a substantially impervious joint between the body or
air fountain and cover of such case.
For this purpose I attach to the side of the oil tank or receiver a number
of springs which press the rim of the body or air fountain against the rim of the
cover and keep the rims of both in close and continuous contact with each other, so
that the lamps may be employed in lighting tram cars and other vehicles without
risk of extinction by reason of the cover being dislodged by shaking and the
current of air being diverted thereby from the flame.
By means of this arrangement where two or more lamps of similar or corresponding
size and shape are in use the oil tanks or receivers may at any time be transferred
if desired from one to another case.
Near the rims of the body or air fountain and cover I form or attach beadings

page_text: of the material of which the same are constructed or of wire, which surround and
strengthen them.
I furnish the oil tank or receiver with a funnel and screw cap at a convenient
place for filling the same with oil and also with a tube attached to the burner and
extending near to the bottom of the oil tank or receiver, and I form both funnel and
tube with nicked ends internally to prevent the oil from splashing up when any
shock or disturbance occurs to the motion of the lamp.
The under side of the air fountain or body of the case is provided with a central
orifice which is intended to be fitted with mechanism such as is employed in the
Hitchcock lamp for creating a constant current of air to circulate about the oil
tank or receiver, and pass afterwards through the burner to the flame.
And in order that my said invention may be more fully understood I shall now
refer to the sheet of drawings hereunto annexed the same letters of reference being
used throughout all the figures to iudicate the same or corresponding parts of my
improved lamp.
Fig. I is a longitudinal section of my apparatus as constructed for use in a tram
car or other vehicle, showing the oil tank or receiver, the nicked funnel and screw
cap, the burner and nicked tube attached thereto, the air fountain or body and
cover of the case, surrounded near to and at their respective rims with beading and
having an open space between them and the oil tank or receiver for the passage of
a current of air, and the arrangement below the case for connecting a Hitchcock
mechanism therewith; and
Fig. II is a cross section of the same apparatus, showing the oil tank or receiver,
the burner and nicked tube attached thereto, the air fountain or body and cover of
the case, and the arrangement for connecting a Hitchcock mechanism therewith as
shewn in Fig. I, also the springs attached to the oil tank or receiver for keeping
the rims of the air fountain or body and cover in close and continuous contact
with each other, and brackets for suspending the oil tank or receiver from
the cover.
a is the oil tank or receiver; b is the nicked funnel with a screw cap, c; d is the
burner, and e the nicked tube attached thereto; f is the air fountain or body,
and g the cover of the case; h, h are the beadings surrounding the rims of the air
fountain or body, f, and cover, g, respectively; is the open space for air passage;
k, k, are the springs attached to the oil tank or receiver, a, for keeping the rims of
the air fountain or body and cover in close and continuous contact; 1, are brackets
for suspending the oil tank or receiver, a, from the cover, g, and m is a socket below
the air fountain or body, f, at the central orifice where a Hitchcock mechanism is
to be attached.
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 I claim
1. The use in paraffin lamps of an oil tank or receiver furnished with springs
constructed and employed substantially in the manner and for the purposes
hereinbefore described and shewn in the drawings hereunto annexed.
2. The use in paraffin lamps of a case consisting of air fountain or body and cover
constructed and employed substantially in the manner and for the purposes
herein before described and shewn in the drawings hereunto annexed, and
3. The combination and arrangement of parts constituting my improved lamp
apparatus constructed and employed substantially in the manner and for the
purposes herein before described and illustrated on the sheet of drawings hereunto
annexed.
