Improvements in Petroleum Lamps and Stoves.
We EDWARD TOOEY, of Lowell, in the County of Middlesex, State of Massachusetts,
Mechanic, and JEREMIAH SARSFIELD HYLAND, of Grand Rapids, in the County of
Kent, State of Michigan, United States of America, Publisher, 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
:-
It is well known that in the use of ordinary kerosene lamps the bodies of the
lamps sometimes become heated to such an extent as to render them extremely
dangerous, a gas or vapor being generated which is liable to cause an
explosion when
ignited and produce the most disastrous consequences, more especially where oils are
employed which are adulterated with naphtha or the lighter products of petroleum.
Our invention is designed to obviate this objection, and to that end we make use
of means which will be readily understood by all conversant with such matters from
the following explanation.
In the accompanying drawing
Figure 1 is a side elevation showing my improved insulator in position for use, a
portion only of the lamp being shown in vertical section.
Figure 2 is a plan view showing the upper member of the insulator and. the burner
proper tipped back into the position they assume when the lamp is being filled.
Figure 3 is a side elevation showing the application of the improvement to an
oil-stove, a portion of the stove being shown in vertical section.
Figure 4 is a vertical transverse section taken on line, a in Figure 3 ; and
Figure 5 is a plan view of the parts shown in Figure 3 the upper member of the
insulator and the burner proper being represented as tipped back to expose the lower
member of the insulator.

page_text: Like letters and figures of reference indicate corresponding parts in the different
figures of the drawing.
In the drawing A represents the burner proper B the body of the lamp or stove
and the wick, these parts being all of the ordinary form and construction. Disposed
between the burner proper A, and the body of the lamp B, there is an insulator D.
The insulator consists of two members m and hinged together at t, to enable
them to be opened or separated as shown.in Figure 2, and provided with a catch
by which they are locked or held in position when the lamp is in use.
v,
The lower member f, is provided with a central hole k, for the wick, and
through which the lamp may be filled, and also with two holes r, for receiving
steadying dowels i, which project downward from the member m. It is also provided
on its under side around the hole, with an exteriorly screw-threaded nipple d, which
is screwed into the body of the lamp B, in the usual manner when the burner is
in use.
The upper member m is provided with a central hole (not, shown) corresponding
with the holek, for receiving the tube for the wick C, and also on its upper side
around said hole with an interiorly screw-threaded socket piece y, into which the
nipple w of the burner A, is screwed in the usual manner.
A packing ring is placed between the members me, and f, said ring being
composed of felt, rubber, or any similar material and preferably secured to the upper
member m, although it may be attached to the lower member if desired.
The members mand f, of the insulator are composed of wood, machic, rubber, or
any similar non-conductor of heat, their object being to prevent the heat from being
communicated from the burner proper A, to the body B, of the lamp.
In Figures 3, 4 and 5, the application of the improvement to an oil-stove is
illustrated, but as its functions are substantially the same as when applied to a lamp
used for illuminating purposes, it is not deemed essential to more fully explain the
same. In the stove shown the wick tube Ir is attached directly to the apper member m,
the other parts of the burner proper not being represented, we do not confine
ourselves to constructing the body of the insulator in two parts or members hinged
together, as it may be made in one piece and provided on its lower side with a
nipple d, and on its upper side with a socket piece y, substantially as shown, if
preferred. Neither do we confine ourselves to the use of the dowels i, and holes 1, or
to any specific form of catch ; nor to exteriorly threading the nipple d, and
interiorly threading the piece y as the screw-threads of these parts may be formed on
the interior or exterior in accordance with the construction of the screw-threaded
parts of the burner proper and body of the lamp.
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
First. As an improved article of manufacture, an insulator for the burner of a
lamp or oil-stove having a body composed of wood, rubber, machie, or similar non-
conducting material, said body being provided with a hole in its centre for the wick,
and on one side with means for connecting it with the body of the lamp or stove, and
on the other side with means for connecting it with the burner proper or wick-tube,
substantially as set forth.
Second. In an insulator of the character described, the members m and ƒ, composed
of wood, machie, rubber or similar non-conducting material, the member m, being
provided with a screw-threaded socket-piece as y, for connecting it with a burner, and
the member f, with a screw-threaded nipple as d for connecting it with the body of
a lamp, said members being hinged together and provided with a catch v for keeping
them closed substantially as described.

Third. In an insulator of the character described, the members m and f, provided
with the hinget, catch e, and packing, the member m, having a screw-threaded

page_text: socket-piece as y, for connecting it with a burner, and the member f, a screw-threaded
nipple as d, for connecting it with the body of the lamp, substantially as set forth.
Fourth. In an insulator of the character described the member provided with the
holes and the member m provided with the dowels i, adapted to enter said holes,
said members being hinged together at t, and provided with a catch &, and packing,
and also with means for respectively connecting them with the body and burner of a
lamp substantially as described.
