Year: 1839

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MORITZ
PLATOW, of Poland Street, Oxford Street, in the County of Middlesex,
Engineer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Sixth day of March, in the second year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Moritz.
Platow, Her especial licence, full power, sole privilege and authority, that I,
the said Moritz Platow, my exors, admors, and assigns,, or such others as
I, the said Moritz Platow, my exors, admors, or assigns, should at any
time agree with, and no others, from time to time and at all times during
the term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "IMPROVEMENTS IN PUMPS OR ENGINES FOR RAISING AND
FORCING LIQUIDS;" in which said Letters Patent is contained a proviso that I,
the said Moritz Platow, shall cause a particular description of the nature of
uy said Invention, and in what manner the same is to be performed, to be
inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Moritz Platow, do hereby declare the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had
to the Drawing hereunto annexed, and to the figures and letters marked
thereon (that is to say):-
My Invention relates to Improvements in Pumps or Engines for Raising and
Forcing Liquids, and for the most part are applicable to that description of
pumps employed for raising or drawing beer; and in order to give the best
information in my power, I will proceed to describe the Drawings annexed,
in which the same letters indicate similar parts wherever they occur.
DESCRIPTION OF THE DRAWING.
Figure 1 represents a pump, particularly applicable to the purpose of raising
or drawing beer.
Figure 2 is a section of Figure 1, by which the internal arrangement of
the parts will be more readily traced and understood. a is the pump barrel,
and 6 are screws and nuts by which such pumps are affixed to the counter or
other place or surface, such screw being affixed to the stand c; and the barrel
of the pump is attached or affixed to the stand c by a screw at d; hence the
pump barrel can be readily removed, and the lower valve got at with facility.
e is the piston, having a central valve, as is well understood. f is the piston
rod, passing through a stuffing box g, formed in the cover h, affixed at the
upper part of the pump barrel a, as is clearly shown in the Drawing. i is the
spout through which the beer or other liquid raised by the action of the pump
is forced. In the upper end of the piston rod is formed a slot or opening,
in which a small roller moves, the axis of which is carried by the lever handlej;
the shape of such lever handle j is shown in the Drawing, and it moves on an
axis carried by the spout. is an ornamental cap or cover, which fits over the
upper part of the pump barrel; this ornamental cap or cover is affixed to the
lever j, and is moved up and down therewith when the pump handle j is put
into action; but when the pump handle j is put back, then the ornamental
cap or cover rests on the upper part of the pump barrel.
Figure 8 shows what is called a lift and force pump, constructed according
to my Invention. In this case the only difference is that the spout is dispensed
with, and there is, consequently, a suitable bracket or support to carry the
axis or. fulcrum of the lever pump handle; and there is an ascending pipe,
with a suitable valve applied; and further, the ornamental cap or cover is
not employed. This pump is affixed to a plank in the ordinary manner of

page_text: such pumps, in place of being applied by screw and nut to a counter or other
such surface, as in the former case.
Figure 4 shows a pump suitably arranged according to my Invention for
such beer engines, are affixed in a case; the same letters indicate similar parts.
In this case the pump barrel is affixed to the back or front of the case by
screws passing through suitable bars or projections affixed to the pump barrel,
as is clearly shown in the Drawing.
Figure 5 shows another arrangement of action for a pump, by forming the
slot or opening in the lever handle of the pump, and on the piston rod is
applied an axis carrying a suitable roller, which works in the slot or opening
of the lever handle, as will readily be understood by examining the Figure of
the Drawing now under description.
Figure 6 shows the section of a beer engine, which consists of a quadrant
of a cylinder having a piston working on an axis at m, there being a proper
valve applied to the piston n, being the induction valve, which, as in the former
cases, is applied to the stand which screws into the counter or such like surface;
and there is a portion of a tube affixed to the lower part of the sector of
the cylinder (in which the piston works), such short tube having a screw
formed thereon which enters the screw in the stand, as is shown in the
Drawing. o is the spout, and p is the lever handle which is affixed to the axis
of the piston external of the pump barrel, passing through a stuffing box for
that purpose.
Having thus described the nature of my Invention, I would have it under-
stood that I lay no claim to any of the parts separately herein described.
But what I claim as my Invention is,-
First, the mode of working the piston rods of pumps by means of a lever
handle and slot or opening in the piston rod, as above explained in respect to
Figures 1, 2, 3, and 4.
.
Secondly, I claim the mode of working the piston rods of pumps by lever
handles having slits or openings to receive axes or studs carried by the piston
rods, as described in respect to Figure 5.
Thirdly, I claim the supporting or carrying of the lever or pump handle
by means of the spout as described in respect to Figures 1, 2, 3, and 4; and
Fourthly, I claim the mode of combining the parts shown at Figure 6, into
a beer engine, as above described.
In witness whereof, I, the said Moritz Platow, have hereunto set my
hand and seal, this Sixth day of September, One thousand eight
hundred and thirty-nine.
MORITZ (L.S.) PLATOW.
