COLIN LONG of 130 Milton Street Walsall in the County of Stafford Leather
Worker, WILLIAM HENRY BURKITT of 66 Lea Brook Road Wednesbury in the
County of Stafford Engineer, do hereby declare the nature of this invention to be
as follows:-
It has a case
To construct acid raisers with renewable parts at small cost.
formed globe shape reduced at the ends which are flanged or otherwise to suit the
inaterial of which they are made, and being hollow therethrough the globe has two
flat sides, ou one flat side there is a branch at an angle of the body for reception of
steam jet pipe, the hole through branch to be square or so shaped that the jet pipe
cannot get out of position, also the branch to be flanged or otherwise to secure the
said jet pipe. One end of case has the ordinary bell end delivery nozzle the jet
pipe has a raised boss for the reception of a renewable steam jet; and being flanged
about midway, and the neck of flange being square or so shaped to fit the branch
and also provision being made for the connection of the steam to the jet pipe.
Mode of renewing the acid raiser When made of regulus or similar metals for
sulphuric acid. Remove jet pipe from case or body fuse up the jet hole with
suitable metal by means of plumbers flame or copper bit replace jet pipe to the
body take out delivery nozzle and replace with guide bush supplied add to the same
a turned drill which may be propelled with an ordinary joiners brace or similar
appliance by this means the steam jet hole is renewed and brought into perfect line
and to standard size at a very low cost.
When made for alkalies and other liquids The renewable jet pipe may be
removed and a small steam jet replaced screwed or by other means.
Providing the acid raiser is made of brittle material the jet pipe is to be extended
accross the body into a cup or rest provided on the opposite internal flat side of
case or body allowing for expansion and contraction and so relieves the weight of
the raising column, thus preventing the jet pipe from being broken.
This mode of renewing and inserting jet pipe applies to bodies of other shapes,
and it may be fixed at any convenient angle.

Improvements in Acid Raisers or Steam Jet Pumps for Raising
Acids, Alkalies, and other Liquids.
We COLIN LONG, of 130 Milton Street Walsall in the County of Stafford
Leather Worker and WILLIAM HENRY BURKITT of 66 Lea Brook Road
Wednesbury in the County of Stafford 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:-
Acid raisers or steam jet pumps as usually constructed are often a great source of
trouble in consequence of the inability of the metal or material of which they are
made to resist the action of the acids. In many instances when the internal steam
jet becomes a little worn it reduces the specific gravity of the acid very considerable
and in some cases collapses after very little work.

page_text: Now the main object of this invention is to construct acid raisers or steam jet
pumps with renewable parts at small cost in such a way as very little skill will be
required for renewing the said parts and so overcoming the difficulties which arise
under ordinary circumstances.
An acid raiser or steam jet pump constructed according to this invention has a
case or body formed globe shape reduced at the ends which may be flanged or other-
wise as illustrated by Figure 1 of the drawings appended which is a vertical section
taken through the centre of the acid raiser. The case or body A formed globe
shape reduced at the ends which are flanged B or otherwise to suit the metal or
material of which the acid raiser or jet pump is made and being hollow therethrough,
the globe having two flat sides C on one flat side there is a branch D at right angle
to the globe shaped body for reception of the steam jet pipe E. The hole through
branch to be square oblong or so shaped that the jet pipe cannot get out of position
also the branch to be flanged or otherwise to secure the said jet pipe. One end of
the case or body having the ordinary bell end renewable delivery nozzle F fitted to
it. The jet pipe E has a raised boss G when made for acids and being flanged H
and neck and flang being square oblong or so shaped to fit the hole in the branch.
In consequence of the metal or material of which they are made the jet pipe E is to
be extended across the body into a cup K or rest provided on the opposite internal
flat side of case or body allowing for expansion and contraction of the said jet pipe
and relieves the weight of the raising column thus preventing the jet pipe from
being broken Provision being made for the connection of the steam which may be
held in place by bolts going through flanges of the jet pipe shewn in drawing or
otherwise to suit metal or material.
Mode of renewing the acid raiser
When made of regulus or similar metals for sulphuric acid (by way of example)
remove jet pipe from the case or body fuse up the jet hole e with suitable metal by
means of plumbers flame or copper bit replace the jet pipe to the body then take
out delivery nozzle F and replace with guide bush fillustrated in Figure 2 of the
drawing add to the same a turned drill 6 the drill is shouldered down d so as to drill
jet hole only and may be propelled with an ordinary joiners brace or similar appliance.
By this means the steam jet hole is renewed and brought into perfact line and to
standard size at a very small cost.
When made for alkalies
The renewable jet pipe may be removed (by way of example) when the worn jet
is of metal the hole may be plugged replaced and drilled in position by means of
drill and guide bush as shewn in Figure 2 of the drawing or a new jet can be
substituted, in this instance the jet may be secured to the jet pipe screwed or by other
means.
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. A steam jet pump for use with acids or alkalies having perferably a globe
shaped body reduced at the ends which are flanged or otherwise and being hollow
therethrough the globe having two flat sides on one flat side there is a branch
perferably at right angle of the body for reception of the steam jet pipe the jet pipe
to be extended across the body into a cup or rest provided on the opposite internal
flat side and so shaped that the jet cannot get out of position substantially as
described.
2. Mode of renewing, inserting and securing jet and jet pipe, constructed
substantially as described and shewn by the drawings herewith.
