PROVISIONAL SPECIFICATION.
Improvements in the Construction of Boot and Shoe Finishers' Gas
Stands, and the like.
We, HENRY.COOPER PRETTY, Florence Villa, St. Saviour's Road, Leicester,
and JOSEPH GARRATT GRIMSLEY of Halford Street, Leicester, Engineers, do
hereby declare the nature of this invention to be as follows:-
This invention has reference to improvements in the construction of boot and
shoe finishers' gas stands, such stands being also applicable for domestic, tailoring,
laundry and other purposes.
The stand or table upon which the to-be-heated iron is placed is divided into
divisions, to prevent the irons accidentally rolling off, and to the underside of the
said table there is movably connected a preferably vertical rod the lower end of
which is secured to a horizontal lever passing partly through the base plate to
which it is fulcrummed and through a slot in a preferably vertical plunger which
the said lever actuates to control the supply of gas to the stand.
The plunger passes upwards through a chamber fixed centrally on the base plate
and provided with rubber or other suitable seatings or equivalent which act as a
guide to the plunger and also serve to prevent the escape of gas.
The gas is directed into the upper part of the said chamber and fixed thereon
is a bell mouthed, conical or tapered tube constructed so that the flame will spread
round the upper portion and with openings at convenient point to admit
atmospheric air to produce the usual blue light.
a
The counterweight is fulcrummed on the upper end of a pillar connected to the
base plate and is constructed with a suitably ball bearing joint so as to be easily
operated..

COMPLETE SPECIFICATION.
Improvements in the Construction of Boot and Shoe Finishers' Gas
Stands, and the like.
We, HENRY COOPER PRETTY, Florence Villa, St. Saviour's Road, Leicester,
and JOSEPH GARRATT GRIMSLEY of Halford Street, Leicester, Engineers, 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 reference to improvements in gas stands for heating boot and
shoe finishers' irons, such stands being also applicable for domestic, tailoring,
laundry and other purposes.
The invention will be understood from the following description in reference to
the accompanying drawing in which :-
Figure 1 is a view partly in section and partly in elevation of a gas stand con-
structed in accordance with this invention.
Figure 2 is an underside plan.

Figure 3 is a plan of the " pan or upper part, the left hand portion showing
the top plate and the remainder the underneath plate and counterbalance" weight
and lever.

page_text: Figure 5 is a longitudinal section on the line Y. Y. of the upper part of the arm
carrying the counterweight-lever.
The same parts throughout the figures are represented by identical letters of
reference.
The stand or table upon which the to-be-heated iron is placed is formed of two
circular perforated plates A and B connected together by pins C.
These plates are shewn in plan in Figure 3 and are identical except as regards
a series of stops A' placed at intervals round the upper plate to prevent the irons
rolling off accidentally.
The lower plate has the usual lever B' carrying the counterweight D connected
thereto and is fulcrummed on the upper end of the arm E as hereinafter
described.
The plate B has movably connected to its underside a vertical rod F the lower
end of which is pivotted to a horizontal lever G passing through a groove or
opening H in the base-plate H and the movement of such lever controls the
supply of
gas to the nipple J as hereinafter described.
The lever G is fulcrummed in a fork E' in the downward extension E* of the
casting E which is secured to the base-plate H by screw bolts K.
It is formed with a gas receiving chamber E and a gas storage chamber E*, the
supply to the former being effected by the delivery pipe L which is connected to
any convenient main gas supply pipe..
The gas to the chamber E is admitted through an opening E' in the wall which
divides the two chambers E' and E.
In the upper end of the chamber E' there is preferably screwed a nipple J
through which the gas escapes and which may be of any suitable construction.
On this nipple is screwed the chimney or funnel M having a series of perfora-
tions M' round its enlarged base to admit atmospheric air.
Across near the mouth of the chimney M there is fixed a short rod N furnished
with a socket N¹ on to which is screwed a plate O or equivalent of a slightly
smaller diameter than the mouth of the chimney and the object of which is to
cause the gas to burn between the remaining space P and thus effect a spreading
of the flame.
This latter object also further assisted by supplementary means consisting of
two or more bars 01 or equivalent fixed crosswise near the narrowest portion of the
chimney and which distribute or diffuse the stream of gas and air in its ascent.
The gas from the chamber E to the nipple J is regulated by a rod Q having a
conical or tapered end 'to fit snugly inside the nipple.
This rod is moved up and down as hereinafter described to cut off or admit a
supply of gas to the said nipple.
The lower end of the rod Q which is preferably of circular section, is grooved
to receive the inner edge of a preferably rubber ring or washer R whose outer
circumference is gripped and held in position between the underside of the
shoulder E' and a ring S whose underside is furnished with lugs S¹ to enable it to
be screwed to the base E8 of the casting E by screw-bolts T as shewn most clearly
in Figure 2.
The up and down movement of the rod Q to regulate the supply of gas to the
nipple J is effected by the action of the horizontal lever G which passes through
a slot or opening Q in the lower end of such rod Q.
A pipe U is screwed into the top of the chamber E so as to communicate with
it and has its upper extremity flattened so that the usual small light termed the
"pilot light" may be constantly burning and ignite the gas at the upper end of
the chimney when the table is lowered as hereinafter described.
In order to secure a free and easy movement of the table or stand, the counter-
weighted lever B is furnished on its underside with a spindle B' which rests on
two or more balls V in the head of the arm E¹ thus forming a ball bearing.
A screw W or equivalent, Figure 5, projects through each side of the head to:
keep the lever B' from lifting out of place.

page_text: The action of the apparatus is as follows:
Upon the to-be-heated iron or tool being placed upon the table A B the latter
is slightly lowered by the weight of the former. The lowering of the table
simultaneously depresses the lever G and link F and the rod Q connected to the
latter admitting gas through the nipple J.
The gas ascends the chimney M becoming mixed with atmospheric air, through
the openings M and eventually becomes ignited by contact with the pilot light in
the top end of the pipe U.
Upon the heated iron being removed from the table the action is reversed; the
raising of the lever G and link F causing the rod Q to become elevated and to fit
snugly inside the nipple J and cut off the supply of gas, the light thereupon
becoming extinguished.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a gas stand such as described the combination of a gas receiving chamber
such as E, communicating gas storage chamber such as E and mechanism for
controlling and regulating the supply of gas therefrom to the nipple J substantially
as described and illustrated in the accompanying drawings.
2. In a gas stand such as described the combination with gas chambers such
as E and E of a rod such as Q or equivalent operated by levers connected to
the tool holding table substantially in the manner and for the purpose described
and illustrated in the accompanying drawings.
3. In a gas stand such as described the combination with the tool carrying
table and counterweighted lever B₁ of a ball joint or bearing constructed and
operating substantially in the manner described and illustrated in the accompanying
drawings.
4. In a gas stand such as described the combination with the chimney of means
for diffusing and spreading the gas flame substantially as described and illustrated
in the accompanying drawings.
5. The improved apparatus constructed and operating substantially in the
manner and for the purpose described and illustrated in the accompanying
drawings.
