PROVISIONAL SPECIFICATION.
Electric Igniting Device, suitable for Lighting Tobacco-pipes
and Cigars.
I, FRIEDRICH WILHELM SCHINDLER, Manufacturer, of Kennelbach near
Bregenz, Austria, do hereby declare the nature of this invention to be as
follows:-
My invention has for its object to provide electric igniting appliances suitable
for lighting tobacco pipes.
For this purpose I make the heating body or the face of it of such a shape and
size that it can be introduced into an ordinary tobacco-pipe, together with the
front part of the metallic casing (if any) which is usually employed to protect
the said heating body..
prefer, to make the heating body of a block of refractory material provided with
numerous perforations, through which the heating wire passes forward and backward
in zig-zag fashion.
The entire heating body may be enclosed in a long cylindrical casing which
slightly projects over the igniting face and is provided with a hollow handle adapted
to enclose the conducting wires.. I prefer, however, to mount the front part of
the heating body, which directly serves to light the pipe, upon a wider base, which
is also cylindrical and enclosed in a metal casing, covered in front by an annular
cap or capsule from the centre of which extends a tubular casing for the front
part of the heating body.
In this case the heating body forms two cylinders, that is a narrow cylinder or
igniting rod adapted to be introduced into a tobacco pipe, and a wide cylinder
which serves as a base. The two cylinders may be made of one block carrying
or containing the heating wire, or each cylinder may constitute a separate heating
body or two heating bodies, wound with wire independently of the others; for
instance one block may serve as an igniting block heated with platinum wire, while
the other block carries a resistance wire made of cheaper metal.
One or more of the heating blocks may be mounted in a metallic casing, by means
of metallic trunnions, or by means of two diametrically opposite lugs which rest in
metal bearings and serve to conduct the current.
A convenient form of pipe-lighter, which can be easily converted into a cigar
lighter, is constructed as follows;
The main body of the apparatus is a cylindrical casing provided with a hollow
handle and containing a refractory block or heating body suspended from a pair
of metallic lugs. Above the said heating body which carries the resistance wire
is mounted in the casing a bridge piece or plate of insulating material which
carries a pair of metallic posts parallel to the axis of the casing. To the top of
the said posts is fixed a smaller heating body (hereafter called the igniting body)
which together with the said posts is enclosed in a narrow cylindrical (or conical)
casing extending axially from the centre of a metallic cap fitted over the open
upper end of the main casing, so as to cover the bridge piece and other contents
of the same.
The narrow cylindrical casing is open at the top and extends slightly over the
igniting body which carries the platinum heating wire and is adapted to be introduced
into the nine together with the and of the narrow casing

page_text: The current is led from the resistance wire or the large heating body to the
igniting body through a pair of wires enclosed in the narrow casing, or it may be
conducted through the posts which support the igniting body.
For converting this pipe lighter into a cigar lighter, the metallic capsule and
narrow casing are removed, together with the bridge piece or plate mentioned
above, the igniting body and the supporting posts, the bridge piece is replaced
by a thin refractory heating block heated with platinum wire connected in series
with the resistance wire, and the capsule is replaced by an annular cap, through
the central opening of which the cigar may be introduced.
If the igniting surface of the electric pipe lighter is formed by a heating body
through which a platinum wire passes forward and backward in zig-zag fashion,
the bends of the platinum wire are situated in grooves sunk in the face of the
igniting block, so as to protect the wire from injury.

CUBIT LUIM DI MUINICATIVA.
Electric Igniting Device, suitable for Lighting Tobacco-pipes
and Cigars.
I, FRIEDRICH WILHELM SCHINDLER, Manufacturer, of Kennelbach near
Bregenz, Austria, 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 has for its object, to provide electric igniting appliances suitable
for lighting tobacco-pipes.
For this purpose I make the said appliance of such a shape and size, that the
heat body or the igniting face can be introduced into an ordinary tobacco-pipe,
and where compactness is desired, I place the heating conductor and the resistance
conductor in the same casing, instead of using an independent resistance.
In the accompanying drawings:
Fig. 1 is a longitudinal or axial section of a pipe-lighter embodying my
invention,
Fig. 2 is a cross section of the same along line x-x of Fig. 1,
Figs. 3 and 4 represent a modification,
Fig. 5 shows another modification,
Fig. 6 a third, and
Fig. 7 a fourth modification.
In the example or type represented by Figs. 1 and 2, the heat body is a
cylindrical block d of refractory material provided with numerous longitudinal
perforations, through which a heating wire c passes forward and backward in
zig-zag fashion and which is surrounded by a metallic casing a. The outer
diameter of the casing a is less than the inner diameter of an ordinary tobacco
pipe measured at the mouth of the same. If the igniting block or plate projects
beyond the casing, in the manner represented by Fig. 7, the casing may be wider.
is a portion of the hollow handle fixed to the casing a. Although the block d
is preferably cylindrical, it may form a truncated cone or other suitable figure.
In the example or type represented by Figs. 3 and 4 the igniting face and the
upper part d' of the heat-body c are similar to those shown in Figs. 1 and 2, but
the lower part d is wider, and the casing is made of two parts, fitted together, as
shown.
'
The igniting rod d" and its base d may form one block of refractory material
containing the heating wire c, as shown by Fig. 3, or they may constitute or

page_text: contain separate heat bodies, each being wound with wire independently of the
other, for instance, one block may serve as an igniting block heated with platinum
wire, while the other block carries a resistance wire of cheaper metal. One or
more of the heating blocks may be mounted in a metallic casing by means of
metallic trunnions or by means of diametrically opposite lugs, which rest in metal
bearings and serve to conduct the current. This inode of fixing has been shown
for a cigar lighter in my Patent Specification No. 25009 of 1893.
A convenient form of pipe lighter, which can be easily converted into a cigar
lighter, is shown by Fig. 5 and constructed as follows:--
The main body of the apparatus is a cylindrical casing a provided with a hollow
handle and containing a refractory block or heat body d suspended from a pair
of metallic lugs, or otherwise secured to the casing. Above the said heat body d
which carries the resistance wire c is mounted in the casing a bridge piece or
plate e of insulating material which carries a pair of metallic posts e', e, parallel
to the axis of the casing. To the top of the said posts is fixed a smaller heat
body (hereafter called the igniting body) which together with the said posts
is enclosed in a narrow cylindrical or conical casing extending axially from the
centre of a metallic cap fitted over the open upper end of the main casing a so as
to cover the bridge piece e.
The narrow casing a¹ is open at the top; the igniting block or heat body
surrounded by the same carries a platinum heating wire c and is adapted to be
introduced into the pipe, together with the end of the said casing a¹.
The current is led from the resistance wire c or from the large heating block d
to the igniting plate d' through a pair of wires c c enclosed in the casing a¹, or
it may be conducted through the posts el ell which support the igniting block d'.
For converting this pipe-lighter into a cigar-lighter of the type described in my
Patent Specification No. 25009 of 1893, the metallic capsule and narrow casing a
are removed, together with the bridge-piece or plate e, the igniting block d¹ and
the supporting posts el ell, and are replaced by the corresponding parts of the
cigar lighter.
A pipe lighter may be similar to that described in my Patent Specification
No. 25009 of 1893 with reference to Figs. 17 and 18 of the same, except that the
upper part of the capsule 9 is elongated, and the igniting plate i consequently
placed at a greater distance from the bridge piece, the said igniting plate and
the part of the capsule enclosing the same being of such a size and shape, that they
can be introduced into the mouth of the pipe.
The pipe lighter, of which Fig. 6 is a side elevation differs from those described
above by the shape of the igniting rod or tube a, which is bent, instead of forming
a straight line; its internal construction may be similar to that described with
reference to Fig. 5.
In the modification shown by Fig. 7, the igniting block projects beyond the
casing, so as to utilize not only the face, but also the sides of the said block.
The capsule or cover a¹ is therefore shorter and has a different shape. This
feature may be advantageously applied to the various forms of. pipe lighter
described above.
The heat body or block in the examples described above is preferably of
refractory earthenware, but may be made of other suitable refractory material.
If the igniting surface of the electric pipe-lighter is formed by a block of
refractory material, through which a platinum wire passes forward and backward
in zig-zag fashion, the bends of the platinum wire are situated in grooves sunk in
the face of the igniting block, so as to protect the wire from injury.
Although I prefer to use heat bodies or blocks of the kind described in my
Patent Specification No. 25009 of 1893, for holding the heating and resistance
wire, because they are capable of containing a great length of wire in a small
space, my invention is not limited to the same, or to the use of heating wires or
coils as described in the said Specification, nor do I wish to claim anything that is
already covered by the Patent mentioned above.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. An electric pipe-lighter comprising in its construction a heat body or igniting
block of refractory material adapted to be introduced with its face into an ordinary
tobacco pipe, a heating wire or other current conductor adapted to heat the said
block, and a portable casing adapted to support and protect the said igniting block
and current conductor, substantially as described.
2. An electric cigar or pipe lighter comprising in its construction a portable
casing provided with a handle and containing the igniting block as well as the
resistance conductor, substantially as described.
3. An electric igniting device comprising in its construction an artificial resistance
enclosed in or held by a portable casing, an igniting plate or block adapted to be
introduced into the mouth of an ordinary tobacco pipe and to be heated by a
conductor connected in series with the artificial resistance, and means for supporting
the said igniting plate at a distance from the said resistance or casing, substan-
tially as described.
4. The various forms or types of electric pipe-lighters described with reference
to Figs. 1 to 7 of the drawings, and the igniting device described with reference to
Figs. 17 and 18 of the Specification No. 2500993.
Dated this 15th day of March 1895.
