PROVISIONAL SPECIFICATION.
Improvements connected with Lighting Torches for Incandescent
and other Gas Lamps.
We,. GEORGE FREDERICK LOMBE FOULGER, of The Common, Upper Clapton,
Gas Engineer, and JOHN GEORGE GLOVER, Engineer, of 214, St. John Street,
both in the County of London, do hereby declare the nature of this invention
to be as follows:-
This invention has for object, the construction or utilization of gas lighting
torches for lighting incandescent and also ordinary gas flames (open or enclosed).
The invention is chiefly intended for lighting street and like gas lamps or
lanterns in which incandescent mantles or the like are used and enables the pilot
or side light to be dispensed with and the ordinary oil or spirit torch to be
employed as at present.
For the purpose of this invention we prepare the torch proper with a hinge so
that the upper part or flame portion can be canted over the uprising gas, say,
of an incandescent mantle, cap or hood on the pulling or by the pushing up of
a wire or rod with which the handle of the torch is provided after the torch
has been inserted into the body of the lamp, the canting being to such an extent
that the gas flame is lighted either through the small quantity passing through
the mesh of the mantle fabric or by the torch being canted over the top outlet
of the mantle for lighting the gas therein from above this being determined more
or less as to the height of the glass or mica chimney if one be used with such
mantles.
Instead of hinging the torch as above it may be so shaped that after insertion
into the lamp a quarter turn will bring the lighting flame of the oil or spirit
within range of the issuing gas for lighting the same. Instead of hinging the
torch or of setting it over at an angle as before mentioned a screen or deflector
hood or plate can be affixed within or to the torch proper for deflecting the oil
or spirit flame or such a screen hood or deflector may be arranged to gather in
the uprising or spreading gas from the burner for lighting it through the mesh
of a mantle or from over one.
The oil or spirit flame of the torch may be acted upon from the side or from
above or through it by a blast or strong current of air suddenly blown across or
into it by a compressor on the release of compressed air from a compressor oper-
able from the handle such as by the push in of a button or the movement of a
catch or an action on a wire or a lever after the torch is placed within the
lantern or lamp.
Such a torch to prevent injury to the flap at the bottom of the lantern from
careless manipulation or otherwise may be protected at its edges by a rim or
edge capping of some non-combustible material such as asbestos, talc or the like
secured by a metal ring or other appliances.

We, GEORGE FREDERICK LOMBE FOULGER, of The Common, Upper Clapton,
Gas Engineer, and JOHN GEORGE GLOVER, Engineer, of 214, St. John Street,
both in the County of London, 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:-
This invention has for object, the construction or utilisation of gas lighting
torches for lighting incandescent and also ordinary gas flames (open or enclosed).
The invention is chiefly intended for lighting street and like gas lamps or
lanterns in which incandescent mantles or the like are used, and enables the
pilot or side light to be dispensed with, and the ordinary oil or spirit torch to
be employed as at present.
For the purpose of this invention, we prepare the torch proper with a hinge
so that the upper part or flame portion can be canted over the uprising gas,
say, of an incandescent mantle, cap, or hood by action of a rod with which the
handle of the torch is provided after the torch has been inserted into the body
of the lamp, the canting being to such an extent that the gas flame is lighted
either through the small quantity passing through the mesh of the mantle fabric,
or by the torch being canted over the top outlet of the mantle for lighting the
gas therein from above, this being determined more or less as to the height
of the glass or mica chimney, if one be used with such mantles.
Such a torch to prevent injury to the flap at the bottom of the lantern from
careless manipulation, or otherwise, may be protected at its edges by a rim or
edge capping of some non-combustible material, such as asbestos, talc, or the
like secured by a metal ring, or other appliances.
Our invention is represented on the annexed drawings.
Figure 1 section of upper part of gas lighting torch as for ordinary lighting
purposes.
Figure 2 exterior elevation of same with the head cauted over .as for incun-
descent lighting purposes.
Figure 3 part sectional elevation of the handle part of the torch stick with a
sliding ferrule and retainer appliance.
Figure 4 elevation of the handle part of the torch stick with sliding ferrule
and the retainer appliance reversed or thrown out of action.
Figure 5 elevation, on a reduced scale, of the torch and stick complete.
The stick is usually solid and the torch head is affixed to it by an outside
socket, but by our invention we purpose affixing the socket within a hollow
stick and the lift rod centrally therein.
is an oil tank. b, a burner. c, the vent. d, a flame shield of tubular
shape and provided with holes e. f, is an outer shield also provided with holes g
out of line with the holes e to protect the flame from wind while the torch is
being carried by the lamplighter. The two shields are connected by the screw
joint which by the shoulder i forms an air space between them and this in
conjunction with the holes e and 9 constitute the means of conveying the flame.
to the gas mixture for ignition. j, is a pin projecting from the oil tank a, and k
is a groove in outer shield f as part of the slot 7 serving as means for the attach-
ment of the shields to said oil well and of easy removal for filling the oil tank,
or for trimming the wick.

page_text: m, is the base of oil well provided with lugs n for pivot pin p of the socket q,
on which pivot the torch head can be canted.
,, are lugs for pivot pin connecting the lift rods to the torch head.
The lower end of the rod s is pivotted to a slider block & free to ride in slot ụ
at the lower part of the torch stick which is hollow as represented.
The hand grip w is connected to the block t and has on the upper and lower
ends projecting lugs,, to prevent the hand of the lamp-lighter slipping, and
ensuring a firm hold on the hand grip w in raising and lowering the torch head.
y, is a latch pivotted at z to stick and capable of being turned to occupy
a vertical position as shown at Figure 3, to lock the hand grip w, or in a hori-
zontal position as at Figure 4, to release the hand grip w for the free movement of
the rods and torch head.
1 is an asbestos cushion secured on top of torch head by 'hollow screw 2.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a lamplighters torch, the combination of canting side pivotted oil lamp
torch head, internal lift rod s attached to base m of oil tank a and to slider hand
grip to respectively as specified and as shown.
2. In combination with side pivotted lamplighters torch head, central rod s
and slider hand grip w, the pivotted latchy arranged substantially as described
and shown.
3. A lamplighters torch head-pivotted at its lower end to the upper end of a
hollow torch stick v, central rod as connecting head and slider hand grip w, lock-
ing latch y near lower end of stick, substantially as specified.
4. A lamplighters torch head pivotted at the lower side portion to socket tube
aud centrally connected by rod to slider block and hand grip, the combination
of asbestos cushion at top of torch head with hollow fixing screw, as specified.
