I, JOHN RUSCOE Engineer and Machinist Albion Works, Henry Street, Hyde in
the County of Chester do hereby declare the nature of this. invention to be as
follows:-
My Invention consists of an improved Self Sealing Retort Lid and Cross bar the
Lid being made with three raised bosses the centre one having a Countersunk hole
and the other two having a Stud in each with screwed ends and nuts and with or
without friction Rollers between the boss and adjustable Nut such pins being made
to pass through the angular Slots fixed in Cross bar and to correspond in position in
the Cross bar to the pins on the Retort Lid and thus securing Retort Lid and Cross
bar together.
The Cross bar is made so as casily to bo fixed to the Lug of existing or other
mouthpiece and to have a central square or V threaded Screw having T handle at one
end and pointed at the other end such Screw passing through centre of Cross-bar
and the pointed end working in the Countersunk hole on the Lid whilst in the Cross
bar two angular Slots are prepared one on either side of the central Screw to receive
the friction rollers or Studs or pins fixed in the bosses on Retort Lid and by the nuts
securing the Retort Lid to the Cross bar itself.
As the threaded screw is forced home an Horizontal Scraping or Sliding motion is
communicated to the Lid and which at the samo time forces the extreme end of Cross
bar into the Catch fixed at the opposite side of mouthpiece to the Lug to which the
Cross bar is also hinged, and when the bar is thus secured and the final pressure of
the Screw applied the Lid besides making the Horizontal Scrape or Slide makes also
a Vertical Scrape or Slide.

page_text: I JOHN RUSCOE Engineer and Machinist, Albion Works Hyde, in the County of
Chester do hereby declare the nature of ibis 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 consists of an improved Self Sealing Retort Lids, and Cross bars, and
Fasteners, the Lid being made with three raised bosses the centre one having a
Countersunk hole, and the other two having a Stud in each with screwed ends, and
adjustable nuts, and with or without friction rollers, between the boss and nuts, such
pins being made to pass through the angular Slots fixed in Cross bar and to corre-
spond in position in the Cross bar to the pins on the Retort Lid, and thus securing
Retort Lid and Cross bar together. The Cross bar is made so as easily to be fixed to
the lug of existing or other mouthpieces, and to have Central Square or V threaded
Screw having T handle at one end and pointed at the other end, such Screw passing
through Centre of Cross bar, and the pointed end working in the Countersunk hole
on the Lid, whilst in the Cross bar two angular slots are prepared one on either side
of the central Screw to receive the friction rollers or Studs, or Pins, fixed in the
bosses on Retort Lids, and by the adjustable nuts securing the Retort Lid to the
crossbar itself. As the threaded Screw is forced home an Horizontal, Angular, or
vertical Scraping or Sliding motion is communicated to the Lid and which at the
same time forces the extreme end of cross bar into the catch fixed at the opposite
side of mouthpiece to the lug to which the Cross bar is also hinged, and when the
bar is thus secured and the final pressure of the Screw applied the Lid besides
making a scrape or slide at an angle to the Horizontal line makes also a vertical
scrape or slide.
And in order that my Invention may be fully understood and readily carried into
effect I will describe the accompanying drawings reference being had to the figures
and letters marked thereon. Fig. 1 is a plan of my Self Sealing Retort Lid, and
Cross bar, Fig. 2 is the elevation of same, A is the cross bar attached to lug of mouth-
piece B.
Cis the catch, D is the screw with point to fit in countersunk hole I, in
the centre boss of lid when in position, e e e are raised bosses, attached to lid H,
FF are studs with adjustable nuts K K, attached to the said raised bosses e e e and
fitting in angular slots G G in cross bar A.

page_text: Having stated the nature of my Invention and described the manner of performing
the same, I would have it understood that I do not limit myself to the details given
as they may be varied or modified and I declare that I claim
1st. The Cross bar A having angular or other Slots G G.
2nd. Raised bosses e e e Cast on or attached to Lid H.
3rd. Studs F F with adjustable nuts K K attached to raised bosses ee on lid H,
and fitting angular or other slots G G in Cross bar A.
In witness whoreof I the said John Ruscoe have set my hand this Eleventh day
of January, One thousand eight hundred and eighty eight.
