Improvements in Means or Apparatus for Regulating and Controlling
the Supply of Gas to Boot and Shoe Finishers' Stands, applicable
also for other similar purposes.
We,
WILLIAM ROBERT MUDD and ALFRED POCHIN, both of Newarke
Street, Leicester, Engineers to the Boot and Shoe Trade, do hereby declare the
nature of this invention to be as follows:-
This invention has reference to improvements in means or apparatus for
regulating and controlling the supply of gas to boot and shoe finishers' stands,
applicable also for other similar purposes.
According to this invention the gas is admitted into an intermediate chamber
within which may be a suitable piston, plunger, valve or equivalent whose action
controls the admission and exit of the gas.
The admission and exit pipes may be on the same level but on opposite sides of
the chamber or at different levels and either one or both of such pipes may com-
municate directly or indirectly with the said chamber.
The piston may consist of a metal block turned to fit the chamber or be of
india-rubber packing or any suitable material or construction.
The piston may be operated to allow or prevent the admission of gas by its rod
being connected to the usual counter-weighted lever attached to the stand.
U Upon the finishers tool being placed upon the stand its weight depresses the
latter and operates the piston or equivalent to allow the gas to flow, but upon the
tool being removed the stand is raised and the piston caused to shut off the supply
of gas.
The piston may be connected at a certain point in its length to a leather disc,
cap, or equivalent fixed over the top of the intermediate chamber by a metal or
other ring being screwed thereon, and which will prevent the escape of gas there-
from, and dirt or other foreign matter getting therein.

COMPLETE SPECIFICATION.
Improvements in Means or Apparatus for Regulating and Controlling
the Supply of Gas to Boot and Shoe Finishers' Stands, applicable
also for other similar purposes.
We WILLIAM ROBERT MUDD and ALFRED POCHIN of Newarke Street,
Leicester, Engineers to the Boot & Shoe Trade, 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 means or apparatus for
regulating and controlling the supply of gas to boot and shoe finishers' stands,
applicable also for other similar purposes.
According to this invention the gas is admitted into an intermediate chamber
within which may be a suitable piston, plunger, valve or equivalent whose action
controls the admission and exit of the gas.

page_text: The admission and exit pipes may be on the same level, but on opposite sides of
the chamber or at different levels and either one or both of such pipes may com-
municate directly or indirectly with the said chamber.
The piston may be of india-rubber or any other suitable material or
construction.
The piston may be operated to allow or prevent the admission of gas by its rod
being connected to the usual counter-weighted lever attached to the stand, and it
may also be connected at a certain point in its length to a leather disc cap or
equivalent fixed over the intermediate chamber by a metal or other ring being
screwed thercon and which will prevent the escape of gas therefrom and dirt or
other foreign matter getting therein.
Referring to the accompanying drawings
Figure is a central vertical section of a boot and shoe finishers' stand con-
structed in accordance with this invention and
Figure 2 is a plan of the same with one-half of the upper part of the "pan
removed.
"
A is the bed-plate and A' is a preferably circular metal block provided centrally
with a chamber B into which the gas is delivered by a pipe C communicating
with the main supply by any suitable connection.
The gas leaves this chamber by two pipes D and E.
The smaller pipe E, passing out of the upper part of the chamber B, is con-
tinuously supplied with gas: it is attached to the tube F by a brace F1 or
equivalent and its upper end is stopped up and all but closed, having an
infinitesimal perforation through which the gas passes, so that an exceedingly
small light, termed the pilot light, may be constantly burning as hereinafter
mentioned.
The other pipe D which furnishes the main supply of gas to the apparatus,
passes
from the lower end of the chamber B with which it communicates, along the
bed plate, through a block A thereon, and terminates in a chamber G.
A burner G, the lower end of which passes into the chamber G, is located
within the tube F screwed on to the block A³ and having at its lower end a number
of holes F to allow the air to mix with the gas during the process of ignition and
thus produce the usual blue light.
The supply of gas to this pipe D is controlled by means of a piston of any
suitable construction or equivalent means. A convenient form of piston may
consist of a rod H having on its screwed lower end a metal disc or washer J
adapted to fit or rest on a rubber ring J¹ or other seating at the bottom of the
chamber B to shut off the gas from the pipe D.
The rod H is screwed into a brace or clip H' pivotted at K' to the ordinary
horizontal lever K carrying at one end the usual counterweight K, and mounted
in bearings L in the upper end of the tubular post or pillar L.
The horizontal lever K has an oblique extension K at its opposite end to which
is connected by screws or other means the perforated discs or circular plates M M¹
forming the usual pan.
In order to prevent the gas escaping from the upper part of the chamber B a
disc N of leather or other material is secured on the piston rod H between two
nuts N¹ N' and is further fixed in position by a metal washer O placed thereover
and screwed on to the block A¹.
Upon the finisher's tool being placed upon the plate M of the pan M M¹ the
latter is slightly depressed and the counterweighted lever K correspondingly
elevated.
Simultaneously therewith the piston rod H is slightly raised so that sufficient
space is left between the disc and the seating ring J1 to allow the gas to
enter the pipe D and escape through the burner G' and ascending the tube F
become ignited by the pilot light 1 at the upper end of the pipe E as before
mentioned.

page_text: 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 :-
1. In an apparatus such as described the combination with the gas delivery pipe
of an intermediate chamber into which the gas is admitted, a piston or equivalent
located therein by which the supply of gas to the burner is controlled and means
for operating the piston.
2. In an apparatus such as described the combination with an intermediate gas
receiving chamber such as B and a piston such as H J of the usual counter-
weighted lever K for operating the said piston substantially as described and
illustrated in the accompanying drawing.
3. The improved apparatus constructed and operating substantially in the
manner and for the purpose described and illustrated in the accompanying
drawing.
