PROVISIONAL SPECIFICATION.
Improvements in Gas Stands for Heating Irons.
We, ARTHUR GILBERT of No. 96 Crafton Street, Mechanic, and ALFRED
MANSFIELD of No. 52 Myrtle Road, Mechanic, both in Leicester in the County
of Leicester, do hereby declare the nature of this invention to be as follows
This invention relates to improvements in gas stands for heating irons, such as
is used by finishers of boots and shoes. The object of which is to provide a
simple but effective arrangement whereby the tool pan is caused to be raised
out of action, or lowered into action vertically instead of tipping, as is now the
case in gas stands used by finishers in heating their irons, such tipping of the
tool pan causing the tools or heating irons often to fall off and causes a lot of
inconvenience, this is obviated by the tool pan being carried upon a forked balance
arm hereinafter described. We also provide a tap which will not "jam" as in
the case of ordinary plug taps the conical plug of which is easily disarranged.
And provision is also made so that the vertical movement of the tool pan is
controlled by a vertical rod attached to the pan, or by pressure spring fitted under
the tap to keep the pan no matter what weight, or position the tools are placed
thereon perpendicular. To carry our invention into effect the stand or apparatus
is constructed in the following manner, the pan upon which the tools are deposited
is of the ordinary kind employed except that it is provided with projections or
lugs upon, or in the centre of the circumference of the lower ring or rim of the
tool pan, into these lugs are fitted the pins from a forked balance arm, carried on
an axle from a bearing or bracket cast in one with the "bunsen burner."
One of the forks is longer than the other, and at its extremity is attached a
connecting rod leading to the crank arm of the tap, having parallel sides, this tap
being fitted into a hole of the size to receive it in the tap body up to the shoulder
of crank arm, but the plug not being made conical it cannot be knocked to fasten
by "wedging or jamming" like a cone plug.
The tap body consists of a flanged cap, internally screwed at top or neck to
receive the screwed end of the "bunsen burner" and bracket cast or attached
thereto.
In a hole in the flange of the tap body is screwed the thin tube "or pilot light"
which is not controlled by the pan, but by ordinary gas cock from supply pipe
under base plate, to which the flange of the tap body is secured.
The base plate
may be circular, or we may provide a tripod consisting of three legs to be screwed
down to a bench if desirable.
When the tools have been placed on the pan it falls vertically, such movement
being controlled by a rod secured to the tool pan entering a slot in the base
plate, or by a pressure spring coiled or otherwise arranged under the tap, and
turns on the tap, which causes the "pilot light" before turned on to ignite the
"bunsen burner" or what is called "the blue light," when the tool is sufficiently
heated, or the tools are ready for use and taken off the pan, it immediately rises
without tipping and the gas is automatically shut off. The long arm of the fork
coming into contact with the underside of the pan in going out of action, and being
opposite to the weight at the outer extremity of the balance arm, and guided by the
rod, or pressure spring as described the tool pan always keeps its perpendicular
and does not tip. Thus ensuring a steady and regulated vertical operation of the

COMPLETE SPECIFICATION.
Improvements in Gas Stands for Heating Irons.
We, ARTHUR GILBERT of No. 96 Crafton Street, Mechanic and ALFRED
MANSFIELD of No. 52 Myrtle Road, Mechanic, both in Leicester in the County
of Leicester 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 relates to improvements in gas stands for heating irons, such as
are used by finishers of boots and shoes. The object of which is to provide a
simple but effective arrangement whereby the tool pan is caused to be raised out of
action, or lowered into action vertically instead of tipping, as is now the case in
gas stands of a similar kind used by finishers in heating their irons, such tipping
of the tool pan causing the tools or heating irons often to fall off and the result is a
lot of inconvenience, this is obviated by the tool pan being carried upon a forked
balance arm hereinafter described and illustrated in the drawing accompanying
this Specification to which I will now refer.
Figure 1 is a side elevation of the stand, and
Figure 2 a cross section of the tap body and "bunsen burner" made in one piece.
The tap illustrated in cross section Figure 2 is specially designed to obviate
"jamming," which is a common occurence by the men hammering in the top of
the ordinary plug taps now employed.
The vertical movement of the tool pan is also controlled by a rod attached thereto
to keep the pan, irrespective of the weight of, or in what position the tools are
put upon the pan, horizontal.
To carry out our invention the stand or apparatus is constructed in the following
. manner. An ordinary pan A, which carries the tools for heating is employed
having projections or lugs 1. upon or in the centre of the circumference of the
lower ring or rim a into these lugs are fitted pins or screws which enter the forked
balance lever 2, carried on the axle 3, in the bearing 4, which is cast with the
"bunsen burner" tube 5, one of the arms 2" is bent and is longer than the other,
and to this long arm is attached the rod B leading to the crank arm C of the
parallel sided tap 6, 6, this tap fitting in a hole in the tap body prepared for it.
The said tap body being by preference cast with the bunsen burner tube 5. The
plug 7, is straight up to the shoulder of the crank C "see Figure 2." Of course
the bunsen, bracket and tap body may be made separately if desired. The thin
tube or pilot light D is screwed into the hole 8 in the base under the tap but is
not controlled by the pan but by an ordinary gas cock E from the supply pipe
under base plate "see Figure 1." The base plate 11, may have feet or may
circular if desired and holes 12, made therein by which it can be screwed down to
a bench or the like. The tool pan or tray A is steadied by the rod 9, secured
thereto and entering a hole at 10, in the base plate. When a tool or tools are put
upon the tray it falls and assisted by the connecting rod B, attached to the bent
arm 2, and crank arm C opens the tap and the bunsen burner 5, takes its light
from the thin tube or "pilot light" which has been previously lit. Upon the
tools being removed the pan or tray rises by aid of the weight F on the outer end
of the balance lever 2 and the gas is automatically shut off.

It will be noticed upon reference to Figure 1, that we do not employ a burner

page_text: inside the "bunsen tube," the road being perfectly clear to supply pipe enables us
or anyone to extricate any obstruction that may get in and stop up, or choke the
gas passage.
By the means as herein described and illustrated the tray or tool pan A is raised
or lowered vertically without tipping forwards which is a great advantage to the
workman in placing, or taking off a tool from the pan.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improvement in a finishers gas stand as herein described whereby a
vertical movement of the tool pan supported by a forked balance lever 2 or its
equivalent, is obtained.
2. In a finishers gas stand the combination of the "bunsen burner" with carrying
bracket for balance arm; the arrangement of "pilot light," and parallel sided tap,
and "bunsen," without independent burner; all substantially as described.
