PROVISIONAL SPECIFICATION.
Improvements relating to Gas Retorts and such like Apparatus.
I, JAMES HENDERSON, of 2, Wilmot Terrace, Osmaston, in the County of
Derby, Engineer, do hereby declare the nature of this invention to be
follows:-
:-
as
My invention relates to gas retorts and similar apparatus or vessels, and has
for its object to provide means of ensuring tight jointing for same whilst
in use under pressure or otherwise and without interfering with their operation.
This I effect by arranging the lid or cover in such manner as to be capable when
securely fixed of a parallel rubbing motion in horizontal, vertical, or angular
directions upon the mouthpiece or bearing surface, whereby any foreign substance
intervening between the two can be removed by attrition and a true and complete
face surface on both parts and a tight joint secured. The lid or cover is operated
and fixed by a bar suitably hinged at one end and provided with a screw fastening
device at the other end. About the centre of the bar a bolt is transversely
inserted which passes also through a slotted hole in a bracket fixed upon the door
adjacent to same; immediately behind said bolt a pin or projection is formed or
fixed on the door, and a hand lever is provided having a hole and an end box or
jaws adapted to fit upon the said bolt head and projection upon the lid or cover
respectively.
By applying the said lever and suitably operating same the lid may be moved
to and fro as required upon the face of the mouthpiece or bearing surface, and
this motion affects the required attrition. The appliance is applicable to lids of
all kinds.

Improvements relating to Gas Retorts and such like Apparatus.
I, JAMES HENDERSON, of 2, Wilmot Terrace, Osmaston, in the County of
Derby, Engineer, 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 relates to gas retorts and similar apparatus or vessels, and has for
its object to provide means of ensuring tight jointing between same and their lids
or covers whilst in use under pressure or otherwise and without interfering with
their operation.
This I effect by arranging the lid or cover in such manner as to be capable when
securely fixed of a parallel rubbing motion in horizontal, vertical, or angular
directions upon the mouthpiece or bearing surface, whereby any foreign substance
intervening between the two can be removed by attrition, and a true and complete
face surface on both parts and hence a tight joint secured.

page_text: I will describe my invention in reference to the accompanying drawing which:
illustrates its application to a gas retort.
Fig. 1 is a plan of the retort mouthpiece and lid with my invention applied
thereto; Fig. 2 is a front elevation of same; Fig. 3 is a side elevation of Fig. 2,
and Fig. 4 a plan of the operating tool.
R is the retort mouthpiece and A is the lid or cover thereto, which is opened,
closed, and fixed by a cross bar B hinged at one end 6 and provided with a
screw fastening device such as b¹ or other suitable contrivance at the other end.
About the centre of the cross bar B a bolt C with projection c on head is trans-
versely inserted, in this case vertically, which bolt also passes through a slotted
hole d in a bracket D formed or fixed upon the lid A adjacent to same and is
there fixed by a nut c'; immediately behind the said bolt Ca pin or projection P
is formed or fixed on the lid, and a hand operating lever L, Fig. 4, is provided
having a hole z and an end box or jaws z¹ as illustrated in Fig. 4, the hole being
adapted to fit upon the head of the said bolt C and the jaws upon the fixed
projection Pupon the lid or cover A respectively.
By applying said lever and suitably operating same, that is to say, in this
instance by moving it from side to side in horizontal planes, the lid A will be
moved accordingly to and fro as required upon the face of the mouthpiece or bearing
surface to about the extent indicated by the dotted lines in Fig. 1, and this motion
effects the required attrition of any intervening dust, grit, or material and secures
a tight joint.
The appliance, though above described in reference to a gas retort, is applicable
to lids of all kinds when applied to their object with metal to metal or face joints,
and the parts may obviously be arranged so that the rubbing motion may take
place in most convenient or required directions.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. Means such as are hereinabove described for ensuring tight jointing between
gas retort mouthpieces and such like apparatus and their lids or covers, consisting
in arranging said lid or cover so as to be capable, when securely fixed, of a rubbing
motion in any required directions upon its bearing surface.
2. The employment in combination with the lid or cover of a retort or such like
apparatus of mechanism such as is hereinabove described, arranged and adapted to
operate substantially in the manner and for the purpose specified.
