I, HEINRICH PHILIPP JAKOB KESSLER of Oberlahustein am Rhein in the
German Empire, Manufacturing Engineer do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN VALVE-COCKS" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement, that is to say :-
My Invention relates to an improved construction of valve-cock whereby firstly
the opening and closing is effected in a simple and rapid manner and with the least
possible wear and tear; secondly, should leakage occur in the course of time any
o..e can readily and rapidly remedy the defect; and thirdly, the simple mode of
construction enables the cock to be made very cheaply.
The construction of the cock will be readily understood on reference to the
accompanying Drawing, in which Figs. 1 and 2 shew respectively a vertical section
and a front view of one form of the cock and Figs. 3 and 4 shew respectively a
vertical section and plan of a modified construction, The barrel of the cock which
may be either bent as at A Fig. I, or straight as at B Fig. 2, is provided with a
seating at F for a valve D carried by the nozzle C which at Figs. 1 and 2 is fitted
to work with a screw thread upon the enlarged part E of the barrel A or B, so
that by screwing up the nozzle by means of the milled rim b, the disc m of the
valve will be made to fit tight against the seat F thus closing the cock, while on
screwing C downwards the valve will be moved away from the seat and the liquid
can then flow round the edge of the valve and past the ribs s supporting the same,
so as to escape through the nozzle.
According to the modification at Figs. 3, 4 and 5, the nozzle K slides with a
cup leather n upon the barrel A and is connected by pins 9 passing through
lugs p to the short forked end of a lever S pivotted at R to the barrel A. The
lever is loaded with a weight H sufficient to keep the valve tightly pressed against
its seat; on raising the lever the valve is lowered, thereby opening the cock.
Figs. 6 and 7 shew respectively a plan of the upper and underside of the valve D..
It consists of a metal disc t having four ribs s on its underside, and a disc m of
leather, caoutchouc, or other material secured in a recess on its upper side by a screw.
The ribs s are so formed as to rest upon the tapering surface of the nozzle; or the
valve seat with its ribs may be cast in one with the nozzle.
Having thus described the nature of my Invention and in what manner the
same is to be performed, I claim
First. Constructing cocks with a moveable valve chamber C or K, and valve D
the up and down motion of which valve chamber closes and opens the cock and

page_text: which at the same time serves as the discharge nozzle thereof, substantially as
described.
Second. In cocks with moveable valve chamber such as referred to in the
preceding claim, supporting the valve D upon ribs s that rest upon or are formed
in one with the valve chamber, substantially as described.
Third, The combination with the barrel A or B of the moveable valve chamber C
or K and valve D the said valve chamber being moved up and down for opening
and closing the cock either by a screw action or by a lever, substantially as
described.
