Improvements in Straight Way Valves.
I EDMUND LUNKENHEIMER of Cincinnati, County of Hamilton, State of Ohio,
United States of America, Manufacturer do hereby declare the nature of this inven-
tion 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 that class of straight way valves known as oscillating
valves, having oscillating or vibrating discs which open and close a straight way
passage through the valve shell and has for its object the improved construction
of such valves whereby they are simplified and rendered more efficient in
operation.
The novelty of my invention will be hereinafter set forth and specifically pointed
out in the claims.
In the accompanying drawings

The shell of the valve is cast in one piece and consists of a chamber A, the

cap
The open end of the chamber A opposite the pipe connections B has an exterior
flange a surrounding it to which is bolted or screwed the removable cap D having

a corresponding flange with intervening packing if desired, the interior of the
and chamber A affording room into which to swing the valve discs out of line
with the pipe connections B B, to open the valve as hereinafter explained, and the
removal of the cap giving ready access to the interior of the valve shell. Journalled
in the tubular portion of the shell is the valve spindle E. This spindle is
preferably square or of other polygonal shape in cross section and is provided at
one end (the upper end in Fig. 4) with an integral frusto-conoidal collar b which
fits into a countersunk bore in the side of the tubular extension C. Slipped over
the opposite end of the spindle E is a second frusto conoidal collar c whose central
aperture fits the polygonal sides of the spindle so that the collar is locked to it in
turning.
This collar c fits in a countersunk bore in the side of the extension and upon
the threaded projecting end of the spindle E is screwed a clamping nut F. By
tightening up this nut or loosening it the collars 6 c may be made to turn with
greater or less friction in their countersunk bores in the extension C. The opposite
projecting squared end of the spindle E is adapted to receive a handle G by which
the spindle may be turned. Fitting on and turning with the spindle E are two
arms or carriers HH' carrying discs I l' arranged to be swung into line with the

page_text: pipe connections B B and to snugly fit against inclined seats J J₁ on the valve
shell. The arms H H have a slight tilting play on the spindle E and the discs [ 1
are inclined relatively to each other as shown and have a ball and socket bearing
interposed between them at K so that as they are swung to their seats J J₁ they
can adjust themselves thereto and be wedged against them to effect a tight joint.
The discs are swung to and from their seats to close and open the valve by turning
the handle G and by means of the adjustable frictional bearings of the spindle E in
the extension C of the shell, the handle G can be made to turn with any degree of
resistance desired and the valve maintained at any degree of opening without the
employment of auxiliary devices for that purpose. By loosening nut F the frictional
bearings may be so adjusted that the handle G may be turned and the discs I l¹
swung to and from their seats very easily while by tightening up the nut the
bearings may be so adjusted that considerable force will be required to turn the
handle and open and close the valve and when the handle is turned to any point and
released it will be firmly held there and the valve maintained at that degree of
opening against all ordinary shocks and jars.
I am aware that it is not new to construct a straight way valve with a shell cast
in one piece and composed of pipe connections in line with each other, a laterally
extending chamber, and a tubular portion in which is journalled a valve spindle which
actuates an oscillating carrier having a disc arranged to be wedged against an
inclined seat in the sheil to close the passage through the pipe connections; nor is
it new to provide a valve having such a carrier with two discs having ball and
socket bearings interposed between the disc and carrier, and inclined seats against
which said discs are wedged by turning the valve spindle, to close the valve all of
which constructions are illustrated in patents granted to me, but I believe the
valve which forms the subject matter of my present invention is the first of that
character in which the two discs are independently supported on the valve spindle
by separate carriers and in that respect it is an improvement upon those above
referred to, for by such construction I am enabled to make a double disc valve much
more compact and of less weight of metal, and consequently much cheaper as well as
to increase its simplicity and the efficiency of its operation. So far as I am aware
also, the valve forming the subject matter of my present invention is the first to
employ adjustable frictional bearings for the valve spindle whereby the resistance
offered to the turning of the valve stem may be varied and the bearings be so adjusted
as to firmly hold the discs at any point to which they may be moved by the turning
of the handle. Such being the case I do not wish to be limited to the particular
form and arrangement of the parts constituting the frictional bearings for the spindle
for these may be largely varied and in Figs. 5. 6. 7 and 8 of the accompanying
drawings I have illustrated some modifications in the construction and arrangement
of these parts. In Fig. 5 the handle G and collar c are shown as cast in one piece
and the spindle E at the opposite end is cut off flush with the surface of the washer b.
In Fig. 6 the handle G collar and spindle E are all shown as cast in one single
piece while the collar c is loose as in Fig. 4. In Fig. 6 also the collars bc are flat
instead of frusto conoidal as in Fig. 4 and they have interposed between them and
their seats in the shell C soft metal washers d. The handle G might of course be
cast solid with the spindle E and collar in the construction shown in Fig. 4 as it is
in Fig. 6.
In Fig. 7 the spindle is provided with an integral bevelled collar as in Figs. 4
and and also with a second bevelled bearing surface at g which fits a bevelled seat
in the shell. The lower end of the spindle in this instance is flat sided and has a
D-washer interposed between the shell and the clamping nut to prevent the latter
being loosened by the movements of the spindle. The above are the several forms of
frictional bearings which I prefer and it will be noticed that in each of them the
spindle E has integral with it a collar which may be caused to hear more or less
tightly against its seat on the shell by means of a clamping nut applied to the
opposite end of the spindle and bearing against side of the shell; but my invention
in its broader scope is not limited to any of these constructions nor to a construction

page_text: in which the spindle E has a frictional collar integral with it, and in Fig. 8 I have.
illustrated a construction in which neither of the collars bc is integral with the
spindle E. In this figure the collar b instead of being integral with the spindle E
forms the flat head of a bolt e which passes through the spindle E and has a threaded
end projecting beyond the opposite end of the spindle. The handle G and collar c
are cast into one piece and are slipped over the end of the spindle E as in Fig. 5. and
the clamping nut F is applied to the threaded end of the bolt e.
This projecting end of the bolte has a flat side or cut away portion and a
D washer is fitted on it and interpose between the nut and handle G to prevent
the movements of the latter in opening and closing the valve, being communicated
to the nut F.
By tightening up and loosening the nut F the collar or bolt head and the collar c
will be caused to bear with greater or less friction on their seats in the shell C and
the same result will be accomplished as in the construction in Figs. 4. 5. 6 and 7. A
soft metal washer is interposed between the collar or bolt head 6 and its seat in the
shell as in Fig. 6.
This feature of my invention, the adjustable frictional bearings for varying the
degree of resistance against which the rocking spindle turns is applicable to valves
having a single oscillating dise and to valves having two oscillating dises supported
on a single carrier as well as to the valve herein described.
My improved valve is particularly adapted for use as a liquid valve as distinguished
from a steam valve though it is also valuable as a valve for steam or gas. For
liquids it is always desirable and generally necessary that the valve employed be a
straight way valve of some sort and ordinary stop cocks and gate valves have hereto-
fore been generally used for this purpose. The gate valves are much more expensive
than my improved valve, and the stop cocks do not prove efficient or durable except
in smaller sizes.
Again in the gate valves which have heretofore been generally used for large sized
liquid valves the valve is usually opened and closed by revolving a hand wheel on the
valve stem and in such cases the degree of opening of the valve is not always easily
ascertained while in my improved valve the position of the handle always shows at a
glance the degree of opening of the valve.
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.
