Improvements in Valves and Valve-gear for Steam and other
Engines.
I, JAMES TAGGART HALSEY, of 132, Nassau Street, in the City of New York,
United States of America, 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 :-
This invention relates partly to valves for steam and other engines and partly to
valve-gear for actuating such valves.
I will first describe the valves, with reference to Figs. 1 to 6.
This part of my invention relates to that class of box-like, wedge-shaped slide-valves,
which are adapted to receive the steam and deliver it to the cylinder through ports in
the valve-walls. In this class of valves, the steam is exhausted from the cylinder into
the valve-chamber, externally to the valve, and passes thence to the atmosphere or to
a condenser, as the case may be.
Fig. 1 is a plan view of an engine provided with the present improvements; a part
of the top-plato of the valve-chamber being broken away to expose the valves.
Fig. 2 is a transverse section substantially on the line 2-2 in Fig. 1.
Fig. 3 is a longitudinal section substantially on the line 3-3 in Fig. 2.
Figs. 4, 4, 5 and 6, are enlarged detail views that will be hereinafter more
particularly described.
A represents the engine-cylinder, B the valve-chamber, and C the main box-like
valve therein. This valve is made wedge-shaped, as seen in Fig. 2. I prefer to make
the incline on the inner face of the valve (that next the cylinder-wall), but this is not
material to the invention. The outer face instead of the inner face or in addition
thereto may be inclined. The valve C has an inlet-port a in its outer face, through
which the steam enters; the said port being elongated and always open to the steam-
inlet a' in the outer wall of the chamber B. In its inner face, the valve has two steam-
ports (Fig. 4), which are made to coincide or register alternately with the corre
sponding steam-ports cc in the cylinder. The chamber B extends far enough beyond

page_text: the working space in the cylinder A to permit of the requisite travel for the valve C.
The ports cc are situated respectively at the ends of the cylinder the valve C
playing over and controlling them. By this construction, I attain the minimum of
clearance at the cylinder-ports; this clearance being measured by the thickness of the
cylinder-wall only.
In order to balance the lateral pressure on the valve C in all its positions, I form in
the inner face of the valve an aperture a*, corresponding in area to the elongated
inlet-port a, and preferably opposite thereto. I also form in the outer face of the
valve, opposite the steam-ports bb, recesses b**, each equal in area to the steam-
ports respectively. This construction is best illustrated in Figs. 4 and 5; the
former being a horizontal section in the plane of the valve-stem, and the latter a

recess * is connected with its opposite port by a closed passage 6 (Fig. 5), which
may take the form of a groove in the top of the valve closed by the top-plate and
connected at its ends with holes extending respectively into the port band recess b*.
This construction balances the pressure while the valve-port and cylinder-port care
in coincidence; but, when one of the ports c is closed by the valve, there is an excess
of pressure on the face of the valve adjacent to the cylinder. This I counterbalance
by the means illustrated in Fig. 4", which is a fragmentary transverse section along
the line in Fig. 4. This device comprises recesses in the inner face of the
outer wall of the valve-chamber B, one opposite to each cylinder-port c, and each
having the same area as its opposite port. Each recess and its opposite port c are
connected by a closed passage 6 (seen best in Fig 4) formed partly in the walls of the
valve-chamber B and partly in the top-plate B¹.
There is a tendency in a valve of this kind-that is, a wedge-shaped valve-io jump
or rise up under certain conditions of compression, which I believe to be due to its
conformation. I obviate this by the means I will now describe.
In the top-plaie B' of the valve-chamber B (see Fig. 6) I mount a cylinder d
closed at the top and open below to the valve-chamber aforesaid. In this cylinder
plays a piston e, the lower end of which rests on the top-plate or crown of the valve C.
This piston e is preferably formed with a projecting flange ex and with a hollow space e',
which latter always covers a small aperture e in the crown of the valve. This allows
the live steam from the interior of the valve C to pass up beneath the said piston and
to act on the under or lower face thereof to lift the same. But the piston e is
provided with a longitudinal passage e³, through which the steam passes to act on its
upper end and press it downwards. Now if the area exposed to the steam-pressure
at the upper end of the said piston be greater than that subjected to a similar pressure
at its lower end, it follows that the prossure tending to force the piston down upon the
valve will be equal to the differential pressure exerted, and may be varied at will by
enlarging or reducing the area at the lower end of the piston; the area at the upper
end being taken as fixed or constant. It is this difference of steam-pressure on the
piston that holds the valve down, and this pressure will vary at all times with the
pressure of the steam in the valve C. For instance, if there should be a sudden
augmentation of the steam-pressure in the valve, tending to lift it from its seat, the
pressure on the piston e, tending to hold the valve down to its seat, will be corre-
spondingly augmented. The flange ex on the piston e is merely designed to give the
proper surface for forming a seat for the piston aforesaid on the moving valve C. I
have shown a spring e arranged above the piston to hold the same down, and a
screw e in the top of the cylinder d for varying the tension of the said spring. This
spring is only intended to hold the piston down to its seat when there is no steam-
pressure available.
It has no appreciable effect when the valve is in operation and the
engine at work.
The recess e in the lower end of the piston e may be elongated so as to allow it to
always cover the steam-inlet-aperture e, whilst at the same time being of a moderately
small area.
In order that the piston may seat itself properly on the crown of the
valve, even though all the parts be not exactly aligned and fitted; I prefer to secure
the cylinder d in the top-plate B' of the chamber B by a kind of ball-and-socket joint.

page_text: That is, the flanged base d* of the cylinder d is formed as a segment of a sphere and
fitted into a corresponding recess in the top-plate B', as shown in Fig. 6. Where
there is no steam in the engine, the spring e serves, in addition to pressing the piston e
against the valve C, to hold the said base d* up to its seating.
The upper end of the piston e (see Fig. 6) is cone-shaped for the reception of a
packing-ring e, the inner lower corner of which bears thereon; the outer face of the
ring fitting against the inner face of the cylinder d. The pressure of the steam
on the said ring keeps it pressed up tightly against both the cylinder and the valve;
the tightness of such packing varying with the pressure of the steam.
I have described one only of these devices for holding down the valve; but, in order
to steady a long valve, I usually employ two such devices, as shewn in Fig. 3. Any
number may be employed, but two will usually suffice.
The steam escapes from the cylinder A into the valve-chamber B when the valve C
uncovers the exhaust port for the time being the said exhaust passing off through
tbe exhaust-pipe D, Fig. 2.
In Fig. 1, E represents the main shaft of the engine, G the fly-wheel thereon, H the
crank, the connecting rod, J the cross-head, and K the piston-rod, coupled to the
piston L, which is shown in dotted lines. These may be of the usual kind and form
no part of my present invention.
The main valve C is coupled to the eccentric on the main shaft E, through the
medium of a tubular valve-stem M, in any convenient manner. This likewise forms
no part of my present invention.
My main valve C is, however, provided with a cut-off valve which I will now
describe; premising that one feature of this latter valve is the limited extent of its
surface which is exposed to the pressure of the steam. The stem N of this cut-off
valve plays through the tubular stem M of the main valve. The stem N is, moreover,
provided with a nut n; the latter being furnished with a projection for engaging
between the guides n' on the back of the cut-off valve, as seen in Fig. 4. By means
of this nut, the adjustment of the cut-off valve with respect to the main valve is effected;
the loose connection of the nut with the cut-off valve permitting the said valve at all
times to be properly seated on the main valve.
The cut-off valve itself comprises two plates y g, which respectively play over
the ports bb. These plates are connected by ties g× 9*. The area subjected to
steam-pressure is limited to the area of the plates g g. A tie or strengthening
web connects the two faces of the main valve C below the lower tie g* of the
cut-off valve.
As the valve-chamber B is not open to the steam supply and the top-plate or
cover B of the same is not employed as an intermediate for the attachment of
either the exhaust or inlet steam-pipes, the said top-plate may be readily removed
for the inspection of the valve, even when the steam is on, provided the ports
are closed by the valve aforesaid.
The device illustrated in Fig. 6 is in the nature of a proportionate pressure-
regulator or governor, as it regulates the pressure on the valve and proportions
it at all times to the pressure of the live steam. Its construction may be varied
considerably without departing materially from this invention.
My improvements may be applied to other classes and kinds of engines and
are not limited to that class shown herein.
The second part of this invention relates to the gear or mechanism for operating
the valves.
Fig. 1 is a side elevation of an engine provided with my improved valve-gear.
Fig. 2 is a side elevation of the shifting eccentric.
Fig. 3 is a side elevation of one form of the eccentric-yoke or strap and its
attachments for actuating the valve-rods. The eccentric in this view is in section.
Fig. 3* is a sectional view on line 3-3 in Fig. 3*.
Fig. 4 is a plan view of the eccentric, its strap, and adjacent parts; the fly-
wheel rim being broken away to show the mechanism carried by the fly-wheel.
Figs. 5, 6, 7*, S* and 9* illustrate other modes of connecting the valve-rods

page_text: to the strap of the eccentric for obtaining the proper relative motions of the
main and cut-off valves.
In Fig. 1 parts of the walls of the valve-chamber and the main valve have
been broken away in order to expose the cut-off valve.
This part of my invention relates to that class of valve-gear wherein an eccentric
is employed for actuating the valve of the engine, and my object is in part to
provide a novel mode of operating both the main and the cut-off valve of the
engine by means of one eccentric, and in part to provide for this purpose a
shifting eccentric, controlled by the governor, for varying the lead, cut-off and
compression.
A is the bed-plate of the engine, B the engine-cylinder, the main or crank-
shaft, and D the fly-wheel on the shaft C. These parts are of the ordinary
construction.
I have shown a governor carried by the fly-wheel. This governor comprises
two similar weights a*, attached respectively to arms xhung at ccx to
opposite arms of the fly-wheel D.
Rotation of the wheel tends to throw out
these weights by centrifugal force, and this force is resisted by springs d d*
connected to the rim of the fly-wheel. In order that the weights may move in
unison, and he controlled in their movements by a single dash-pot or regulator E,
I connect both arms, by rods or links ffx to a controlling lever e. The
latter is pivoted to one of the arms of the fly-wheel.
The eccentric G resembles
a ring and loosely embraces the main shaft C. It is secured to, or by preference
cast in one piece with, a carrier-plate G (seen best in Fig. 2*); the latter being
pivoted at to one of the fly-wheel arms. When the plate G₁ oscillates about
the pivot a, it changes the relative position of the centre of the eccentric with
regard to the main shaft and thus varies the throw of the valve-rods, as also the
points at which the valves open and close the ports. The carrier-plate is shifted
by the governor by means of the following mechanism :-A slot is formed in
that portion of the carrier-plato G¹ situated on the opposite side of the main
shaft to that on which the said plate is pivoted; a slide-block y' playing within
this slot and having a hole to receive a pin or stud projecting from one of
the governor-weights a. The axis of the slot is arranged obliquely to the path
traversed by the stud when the weight a is moved, and consequently oscillation
of the said weight will swing the carrier-plate, and with it the eccentric, and thus
vary the position of the latter. The plate G¹ is guided in its movement and is
kept against the face of the fly-wheel by means of bolts fixed in lugs i on the
fly-wheel boss; the said bolts engaging in slots in the plate G¹ aforesaid. His
the eccentric-yoke or, strap, seen in Fig. 3* in elevation. In this yoke is fixed
à laterally-projecting stud or pink having a bearing in a slide playing in a
guide m bolted to the side of the bed-plate. Above the pin in the yoke H is
another similar pin ; and to the latter is coupled the rod o of the cut-off.
valve 1; the said rod boing jointed to the stem o of the cut-off valve aforesaid.
To the slide is secured the rod p of the main valve J; the said rod being
rigidly secured to the tubular stem p¹ of the said main valve. In the construction
shown in the principal Figures, the stem of the cut-off valve I plays through the
tubular stem of the main valve J; but this is not an essential feature. Both
valves are actuated by the same eccentric and yoke. The main valve is moved
to and fro a distance substantially equal to the throw of the eccentric; the cut-
off valve being moved to and fro on the main valve a distance corresponding.
with the oscillating movement of the point n about the point k.
It will be seen
that, when the eccentric revolves, the cut-off valve will be carried to and fro with
the main valve in addition to having imparted to it an independent movement on
the said main valve for effecting the cut-off in the usual way. By arranging the
axis of the guide m to pass, if prolonged, to one side of the shaft C (below, as
arranged in Fig. 1*), I am enabled to bring the main valve substantially to a
state of rest at the end of its stroke, and to maintain it at rest for a considerable
time at this point.

page_text: (
In Figs. 5, 6 and 7*, I have shown other modes of coupling the valve-rods
to the yoke of the eccentric. In Fig. 5 the coupling is direct, as in Fig. 3*,
but the rods and o are connected respectively to lugs s and on the eccentric-
yoke on opposite sides of the block on which the said yoke moves to and fro.
The latter is provided with a slot for the reception of the block aforesaid,
which is mounted rotatively on a stud projecting from the bed-plate or some
other fixed part of the engine. In Fig. 6 the stud or pin n projects from a
downwardly-extending arm on the yoke H; the rod being connected to the
stem o through the medium of a rocking lever pivoted to a block on the
rod . In Fig. 7* the eccentric-yoke is coupled to the rod p of the main valve
in substantially the same manner as in Fig. 3*, but the said yoke imparts motion
to the stem o of the cut-off valve through the medium of a connecting link v,
a bell-crank lever », a connecting rod o and the rocking lover . By properly
proportioning the arms of the intermediate levers, almost any desired extent and
kind of motion may be imparted to the cut-off valve by the yoke of the eccentric ;
this intervention of levers, such as v and u, forming an important feature of my
invention.
Fig. Sis a side view similar to Figs. 5*, 6 and 7*, but illustrating another
form of my valve-gear wherein a rocking arm is substituted for the slide
and its guide in order to obtain a movement in substantially a straight line. The
arm and the slide are equivalent devices for coupling the eccentric-yoke to
the valve-rod. Fig. 9 is a sectional front view of this arrangement; the plane
of the section being indicated by the line 9-9 in Fig. 8*. The rocking arm
is connected to the yoke Hat k, and, at its free extremity, to the upper end of
a rocking lever u', carried by the yoke aforesaid. The lower end of the lever u¹
is jointed to the stem o of the cut-off valve. The main valve-stem is actuated
through a rod p connected to the rocking armats. This construction has
special advantages, as it enables the arm of the eccentric-yoke to be extended out
far enough to clear the fly-wheel or other parts of the engine.
In Figs. 5, 6, 7*, S* and 9*, I have omitted all accessory parts, which are
of the usual description, in order to avoid obscuring special constructions it is
desired to illustrate therein.
The slot in the carrier-plate G₁ (Fig. 2*) may be formed in the solid plate,
but prefer to build it up, as illustrated, for convenience of manufacture or
renewal.
The regulator E is a closed cylinder, filled with oil or other fluid, in which a
piston on a prolongation of the rod fx, which enters the cylinder through a
stuffing-box, loosely plays. This device serves to regulate the action of the
governor-weights.
The block (Fig. 2) and the block (Fig. 5*) are only contrivances of a
well-known kind to provide bearing surfaces and to prevent the wear of the pins
upon which they are respectively mounted.
