I, JOHANN KROOG, of Halle-on-the-Saale, in the Kingdom of Prussia and German
Empire, Civil 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 apparatus for the automatic discharge of water of
condensation from steam pipes or atmospheric air from water pipes, and for similar
purposes.
In the accompanying drawings.
Figure 1 is a vertical longitudinal section of my improved apparatus.
Figure 2 is a horizontal section of the same.
Figure 3 is a vertical transverse section through the valve-chest, and
Figure 4 is a similar section through the end of one of the caps.
My improved apparatus is applicable for automatically discharging liquids, fluids or
gases and is arranged and constructed as follows.
a is a valve-chest having the inlet pipe or conduit b and the outlet pipe or conduit c
the said pipe or conduit c contains the valve-seat e on which is seated the valve d. A
rod or link fis pivotally connected with the valve d and with the two-armed lever I
by means of the bolts i and m. The two arms of the lever g which is pivotted at n to
the valve-chest a are of unequal length.
The bolts or pivots i m and n are smooth cylindrical pins which are prevented from
falling out of their holes by the walls of the casing after the latter has been put
together and closed. On taking off the caps h and ' of the said casing, the levers
enclosed therein may be readily taken out of the same by removing the said bolts
or pivots.
is a perforated plate or sheet of metal which is bent into the proper shape and
serves the purpose of retaining the coarser particles of dirt or other matter. The
said plate is carried by the two supporting flanges o of the valve chest, and its
vertical end-faces s enter the spaces between the caps h, h¹ and the valve-chest a so that
by these means the said perforated plate is held in position while, at the same time, it

page_text: admits of being readily removed from the apparatus in order to be cleaned or
repaired.
The lever g carries on its short arm the weight p and on its long arm the weight y.
These two weights p and q are of the same volume, but are made of different materials
and the distances of their centres of gravity from the point of oscillation or fulcrum
of the lever are in inverse ratio to their specific weights.
The lever g and the weights p and q carried thereby are, therefore, in equilibrii if in
the use of the apparatus as a trap for discharging water of condensation, they are
surrounded by air. As soon, however as water enters the apparatus, this equilibrium
will be disturbed in consequence of the rising tension, which is alike to both weights
but which acts upon two levers of unequal lengths so that the valve d will be lifted
from its seat and the outlet-conduit c opened.
If the same apparatus is to be employed as a means for the discharge of air, it will
only be necessary to connect the conduit 6 with the water conduit which is to be freed
of air, and to reduce the weight q by so much that the lever g with the weights p and q
will be in equilibrio while surrounded by water, instead of by air, so that an automatic
opening of the valve d must now take place in case of air collecting in the apparatus.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
-
First. An apparatus intended for use in automatically discharging liquids, fluids or
gases, the said apparatus being characterized by the arrangement, in a casing
consisting of a valve-chest (a) and caps (h h¹), of the lever g carrying on its two
arms which are of unequal lengths the weights p and q. whose distances from the
fulcrum (n) of the lever are in inverse ratio to their specific weights, substantially as,
and for the purposes, set forth.
Second. The arrangement, in the valve chest a, of the removable perforated plate l
securely held against lateral displacement and adapted to prevent the entrance of the
coarser particles of dirt or other matter into the valve-chest a.
Third. The arrangement of the smooth cylindrical bolts or pivots (m n i)
substantially as described so that they are prevented by the walls of the casing of the
apparatus from falling out of their holes, as above specified.
