"Improvements in Cocks or Taps."
I, ADAM SCHLEIDT, of 12, Bleichstrasse Wiesbaden; in the Empire of Germany,
Executive Official of the Courts do hereby declare the nature of this invention to be
as follows:-
This Invention relates to a cock for use in water pipes and the like, in which all
packing material such as india rübber or leather is entirely dispensed with.
The closing part or member of this cock is the cone which is located in a
corresponding recess within the cock casing and is provided with the two openings.
In one position these two openings correspond with two channels in the cock casing.
If, however, a knob adapted for operating the cone is turned towards the right hand,
the cock will be closed."
The cone is turned by means of a pin one extremity of which enters the central
guide or pivot rod of the cone, the other extremity being lodged between the two
screw-threaded portions of a ring, in which position it is firmly locked when the
aforesaid knob or nut is screwed on, and, by being moved to and fro in a
corresponding space in the body of the cock, effects the opening and closing of the
latter.
In order to effect à diminution of the pressure in high-pressure conduits and thus
prevent shocks to the cock or bursting of the conduit, the cone is provided with a
central rod upon which are arranged discs or washers the disc or washer nearest the
source of supply being provided with inlet openings and the succeeding discs or
washers with oblique slots, which latter impart a spiral movement to the water as it
passes through and so breaks its force. The cone, the central rod and the discs may
advantageously be made in one piece.
Improvements
İ, ADAM SCHLEIDT, of 12Bleichstrasse Wiesbaden, in the Empire of Germany,
Executive Official of the Courts 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:-
This invention relates to certain new and useful improvements in cocks or faucets}

page_text: and it consists substantially in such features of construction, arrangement and
combinations of parts as will hereinafter be more particularly described.
The object of the invention is to provide a cock or faucet comparatively simple in
construction, and one in which the use of all packing material is dispensed with.
A further object of the invention is to provide means whereby when the cock is
closed there will be no liability to dripping; and also to provide for the easy
manipulation of the cock as well as the general efficiency in the performance of its
function, as such.
These and other objects I attain by the means illustrated in the accompanying
drawings in which
Figure 1 is a longitudinal sectional view taken in a horizontal plane to the cock
when in position for use.
Figure 2, is a similar view taken in a vertical plane, or at right angles to
Figure 1.
Figure 3 is a left hand end view, a side view, and a right hand end view,
respectively, of the valve and its stem, together with the safety or pressure regulating
discs mounted upon or carried by the stem.
Figure 4 is a sectional view taken on the line 1, 1, of, the central part of Figure 3.
Figure 5. is a cross-sectional view taken on the line 2, 2 Figure 2.
Figure 6, is an end view of the cock or faucet, showing in dotted lines the
coincidence or registry of the ports of the valve with the channels or passages of the
seat therefor in the shell or casing.
Figure 7, is a similar view representing the valve as cut off or when the inner
outlet passages and the valve ports are out of registry or coincidence.
Figure 8 is a view in perspective of the cock or faucet as it appears complete and
ready for use.
Figure 9 is a view in detail of the devices which co-operate with the valve for
opening and closing the latter and
Figure 10 shows a modified form of valve stem.
My invention is capable of being embodied in different ways, but as a simple and
effective construction I have selected the form herein shown, and which will now be
described. The shell or casing of the cock or faucet is designated at A, and which
as shown is formed with the usual downwardly curved mouth portion B, constituting
the outlet or discharge. The said shell or casing has a rearward extension C, which
terminates in a reduced screw threaded nipple 1, for securing the faucet in place;
and intermediate the inner ends of the extension and the curved mouth portion B,
is a solid portion E, having preferably two longitudinal passages e, f, forming a
communication between the hollow extension C, and the said mouth portion
or discharge B. The said passages are preferably arranged at diametrically opposite
points, but it is obvious that both the position and number of said passages could be
altered or changed to suit requirements. The body of the shell or casing is preferably
somewhat enlarged at b, and a, cavity or recess m, is formed therein, leading
preferably from the upper side of the shell and extending into the solid portion E,
for about one-half the diameter thereof, the said cavity reaching to and
communicating with a central longitudinal socket 1, formed in the said solid
portion.
A suitable thickness of material is left between the passages e, f, and the cavity
or recess m, and the sides of the latter converge inwardly and are substantially
triangular, and they constitute limiting stops or abutments for the valve operating
devices to be described.
5
The inner extremity of the solid portion E, is dished or concaved, and constitutes
a seat for a substantially conical and rotary valve a, carried on a longitudinal stem ¹,
the said valve being formed with lontiudinal ports c, d, adapted to coincide with the
passages e, f, and the said stem extending at its inner end beyond the valve and
resting or having its bearing in the socket 7. The valve can be operated in many 5
different ways, but as a convenient way I fasten in an opening h, in the inner end of
the stem thereof, at the side, the inner end of a pin g, having an oscillating

page_text: movement back and forth between the two convergent sides of the cavity m, and the
upper end of this pin extends beyond the side of the shell a short distance so as to
enable the pin to be conveniently manipulated for opening and closing the ports
of the valve. The said pin can be moved back and forth in the recess m, as far as
perinitted by the sides of the latter, and this of cource is the limit of movement of
the valve in either direction, since the stem of the valve is turned with the pin.
The said pin g may be disposed in various ways to operate the valve, but preferably
I employ a two-part ring n, a fitting and turning within an annular groove formed
in the enlarged part b, of the shell. The two parts of this ring are hinged together
at 2, Figure 9 and their free extremities are formed with semi-cylindrical
projections k, l, which are screw-threaded exteriorly to receive a knob or button l'.
The outer extremity of the pin g, is received between or within the portions k, k¹,
and it is obvious that by taking hold of the knob and turning the ring in its groove,
the pin g, will be turned and consequently the valve. In the position of the knob
as shown in Figure 6, for instance, the ports of the valve will be in coincidence with
the passages e, f, and the cock is then open; and in the position represented at
Figure 7, the ports will be brought to a position substantially at right angles to the
passages, and the cock will then be closed.
It will thus be seen that I have provided a very simple and effective faucet ; but
in addition to the features described I also provide means for effecting a diminution
of water pressure in high pressure conduits, and thus prevent shocks or hammering
of the cock, as well as the bursting of the conduit. This feature of my invention,
it will be understood is equally applicable to cocks or faucets of other constructions
than that herein represented. Thus I provide the valve stem of a length about
equal to the extension C, of the shell and I provide the same with a number of discs
(three being shown in the present instance) p, q and r. The outermost of said dises
isformed with longitudinal passages p', while the remaining ones of the discs are formed
with diagonal passages or openings q', crossing each other, as shown. The form and
arrangement of the openings described, gives to the inflowing water a spiral
movement, and the pressure of the water is thereby diminished with no liability to
bursting of the cock.
In some cases the valve body shewn in Figure 3 may be replaced by a simple cone
with longitudinal grooves as shewn by Figure 10. In this case the valve seat is
provided with a corresponding conical bore.
It is obvious that immaterial changes can be made in the construction and
arrangement of the several parts, and therefore, without limiting myself to the
precise details shown and described.
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 :-
1. A cock or faucet provided with interior longitudinal passages leading to the
discharge, and a rotary valve having ports adapted to register with said passages,
substantially as described.

cavity and connecting with the stem, and a two-part ring turning in a groove in the
shell and provided with the semi-circular projections k, k, einbracing the outer end
of the pin, and the knob or button, substantially as described.
