Year: 1879

page_text: ☐ LETTERS PATENT to Carl Pieper, Civil Engineer and Patent Agent, of
74, Belle Alliance-Strasse, Berlin, S.W., Prussia, for the Invention of
"IMPROVEMENTS IN PUMPS." A communication from Wilhelm Garvens, of
Hannover, Germany.
Sealed the 28th October 1879, and dated the 1st May 1879.
PROVISIONAL SPECIFICATION left by the said Carl Pieper at the Office
of the Commissioners of Patents on the 1st May 1879.
CARL PIEPER, Civil Engineer and Patent Agent, of 74, Belle-Alliance-Strasse,
Berlin, S.W., Prussia. "IMPROVEMENTS IN PUMPS." A communication from
Wilhelm Garvens, residing at Hannover, Germany.
This Invention relates to improvements in pumps for domestic & industrial
purposes, and consists in the use of a pedestal forming a chamber, in which are
enclosed the internal working parts of a pump.
This pedestal is formed in such a manner that the parts therein contained may
be operated from the outside by means of a shaft passing through a suitable.
stuffing-box, the outside part of the said shaft being provided with a lever acted
upon in the usual manner.
To the upper part of the said pedestal is secured a standard or stand-pipe of the
desired size and description, provided with one or more spouts, and to its lower
part the barrel containing the piston & the necessary valves, the pedestal itself
being fixed to the cover of the well or reservoir from which water is to be drawn.
By this arrangement any kind of pump-standard may be adapted to the pedestal
to suit the requirements of the users, whereby the necessity of the pump-makers
having a great selection of ready finished pumps is avoided, & free and rapid access
may be had to all the internal parts by merely removing the standard; moreover,
the said pedestal being closed no dirt can enter the pump or the well, as is generally
the case with the ordinary construction of pumps on account of the unavoidable
holes necessary to the working of the lever.
The above described pedestal may also be adapted with the same advantage to
pumps having two cylinders, and in this case it is provided with two covers applied
directly above the cylinders, so that the standard need not be detached, access to
the internal parts being obtained by merely removing the said covers.

the said Carl Pieper in the Great Seal Patent Office on the 30th October

CARL PIEPER, Civil Engineer and Patent Agent, of 74, Belle-Alliance-Strasse,
Berlin, S.W., Prussia. "IMPROVEMENTS IN PUMPS." A communication from
Wilhelm Garvens, of Hannover, Germany.
This Invention relates to improvements in pumps for domestic and industrial
purposes, and consists in the use of a pedestal forming a closed chamber which
contains the internal working parts of a pump.
The said pedestal is constructed in such a manner that the parts therein con-
tained may be operated from the outside by means of a shaft passing through a
suitable stuffing-box, the outside part of the said shaft being provided with a lever
acted upon in the usual manner.
To the upper part of the said pedestal is secured a standard or stand-pipe of the
desired size and description, provided with one or more spouts, and to its lower part
the barrel containing the piston and the necessary valves, the pedestal itself being
fixed to the cover of the well or reservoir from which water is to be drawn.
In Fig. 1 and 2 of the accompanying Drawing, A is the barrel secured by a
flange to the pedestal B. This piston C is jointed by the intervention of its rod D
to a lever E, made fast upon the shaft F. This shaft passes towards the outside of
the pedestal B through a stuffing box, and is supported at its end in a special
bearing G. Upon the outside part of the said shaft is fixed a socket H for the
reception of the lever I; or the lever, especially when made entirely of metal, is
fixed directly to the shaft F.
Figs. 3 and 4 represent on a larger scale sections of the pedestal with its internal.
arrangement, which forms the main part of this Invention, and upon which may
be secured any kind of standard to suit the requirements of the users.
The accompanying Drawing contain different kinds of standards for some of the
most frequent uses. Fig. 1 shows a simple standard with spout, and Fig. 2, a
standard with spout and with an air vessel, the spout having a stop-valve and its
end being screwed so as to receive a hose-pipe for watering and other purposes; the
barrel A is provided with a cock, by means of which the water may be directed
into a pipe L for leading it through the wall of the well.
The pump-standard might have two spouts placed at different heights, the lower-
one of which could be closed by a screwed cap; under the other spout a bracket or
support might be fitted, upon which is placed the vessel to be filled, or the wooden
buckets carried on the back, as is usual in the South of Germany.
Instead of a straight standard a bent tube might be used, serving at the same
time as a spout.
By this arrangement any kind of standard may be fixed to the pedestal, thus
avoiding the necessity under which pump-makers are at present of having a great
selection of ready finished pumps in stock to meet the different requirements of the
users.
It will be observed that whenever the standard is detached from the pedestal.
ready access is obtained to the interior working parts, and the piston, as well as
the valve, may be extracted from the barrel, provided, however, that the said valve
be constructed suitably for the purpose, as shown in the Drawing.
Fig. 5 represents a modified arrangement of pedestal adapted for two pump-¯
barrels or cylinders, the piston-rods of which are jointed to a double branched.
lever E¹ keyed on a shaft passing to the outside of the pedestal, as in Fig. 1 to 4.-
The outside working lever is shown in Fig. 5 as being also double-branched. P, P,
are covers placed above the pump-barrels, so that when these covers are removed
access is obtained to the interior of the pedestal in a similar manner, as by the
removal of the standard of the pumps shown in Figs. 1 and 2. With the standard

page_text: of this pump a movable discharge pipe M is supposed to be combined serving for
filling water-carts, small locomotives, &c. The standard may also be fitted with a
spout provided with a stop-valve, as in Fig. 2.
In addition to the main advantage of this Invention, which has already been
mentioned, the described construction of pump presents the further advantages that
the internal parts of the pump are very readily accessible and that no dirt can
enter into the pump or the well, as is generally the case with the ordinary con-
structions of pumps on account of the holes necessary for the working of the lever
or the piston-rod. Moreover, the shaft of the lever being very securely mounted in
its bearings the working parts of the mechanism are not liable to become loose and
to take play, and the power applied to the lever is utilised very advantageously.
It is finally to be remarked that the above described pedestal might be combined
with separate pumps having special discharge-pipes and suitable connecting-rods,
provided however that the form of pedestal shown in the Drawing be modified
according to the purpose for which it is intended.
Having thus described the nature and object of this Invention, and the manner
in which it is to be carried out in practice, as communicated to me by the inventor,
I hereby declare that I do not wish to limit myself to all the precise details, as
herein before specified and represented by Drawing, but I claim as the new and
important feature of the said Invention,-
A pedestal containing the internal working lever of a pump, arranged as above
described and shown, and for the purposes set forth.
In witness whereof, I, the said Carl Pieper, have hereunto set my hand and
seal, this Third day of October, in the year of our Lord One thousand eight
hundred and seventy-nine.
CARL PIEPER. (L.S.)
