Improvements in Steam Engines.
I JOSHUA ENTWISLE, Manager with the Firm of E. K. Dutton & Co.,
Chartered Patent Agents, of 5 John Dalton Street, Manchester, in the County
of Lancaster, do hereby declare the nature of this invention (communicated to
me from abroad by Edward Kittredge Hill of the City of Worcester, County of
Worcester, Massachusetts, and Joseph Hinson Webster Hoadley, of Chicago, Cook
County, Illinois, United States of America, Manufacturers,) to be as follows:
The object of this invention is to provide a steam engine in which the working
parts are arranged in an efficient, convenient and compact manner, so that they
may be capable of simple and convenient adjustment, the friction reduced to a
minimum, and the engine rendered capable of accurate regulation.
The bed-piece, cylinder-casting and pillow-block may be of any of the ordinary
or approved constructions.
In practice, this invention has been employed in engines embodying features
which are employed in what is known as the "Wheelock engine," although it is
evident that the invention, as hereinafter described, may be used in connection with
any other engine, to which it is found to be applicable.
A removable shell or plug is fitted into each end of the cylinder casting, and is
preferably held in place by means of a bonnet or washer.
Each of the plugs is provided with transverse bearing strips or surfaces, which
are arranged to co-operate with and fit tightly against bearing surfaces in the
cylinder casting.
Mounted in each of the removable shells or plugs is a sliding, gridiron, inlet
valve, and a sliding, gridiron, outlet valve, arranged to work transversely of the
cylinder, and to co-operate with suitable valve-seats in the plug.
In the use of plugs or shells, which are provided with seats for the inlet and
outlet valves, it has been found that the pressure of the steam acting on the inlet
valve-seat is apt to strain said seat, and prevent the bearing surface of the plug
from fitting tightly against the bearing surface of the cylinder casting, thus
producing leakage, and interfering with the efficiency of the engine.
To overcome this defect, each removable plug or shell is provided with a brace
or strut, which is secured above the outlet valve, and is adapted to re-enforce and
stiffen the inlet valve-seat.
This strut or brace is preferably made in the form of a ladder or grating.
In the use of steam engines, it sometimes happens that the presence of water in
the cylinder produces an abnormal pressure, and the parts of the engine may be
strained, or the cylinder-head blown out.
To overcome this difficulty, it is desirable to have the inlet valve held against its
seat by means of spring tension.
To allow for this action, the removable shells or plugs are provided with a
removable piece or section containing springs and followers, engaging with the
inlet valve.
Fastened upon the end of each removable shell or plug is a removable head,
which forms a support or bearing for the valve-operating mechanism.
In practice, this is a desirable feature of construction, as the valve-operating
mechanism may be finished independently of the plug itself, and, as the same valve-
operating devices may serve for several different sizes of engines, the heads may be

page_text: of the engine.
The valve-actuating mechanism is driven from a valve-actuating shaft journalled
in boxes secured to the cylinder-casting.
vvapting and simplying the construction
The valve-actuating shaft is connected by a universal joint and clutch to a power
shaft geared to the main shaft of the engine.
When the clutch is disconnected, the valve-actuating shaft is free to rotate, and
is provided with a capstan head for turning the same, and thus actuating the valves
of the engine by hand.
The use of a universal joint for connecting the valve-actuating shaft with a power
shaft is a desirable arrangement, as by means of this construction, the same
mechanism for actuating the valves can be used in different sizes of engines, and
the valve-actuating shaft can be conveniently coupled to and driven from the main
shaft of the engine, independently of their relatively positions.
Rigidly secured near each end of the valve-actuating shaft, are collars having
face-plates.
Detachably secured to the face-plates are eccentric disks for actuating the
valves.
These eccentric disks are each provided with a bolt extending through a slot in
the face-plate, and each eccentric can thus be independently adjusted and clamped
in position.
As an eccentric is provided for each valve of the engine, the valves may be
independently adjusted and regulated by means of these adjustable eccentrics.
The intermediate connections for actuating the valves at each end of the cylinder
are duplicates of each other, and a description of one such set of connections will
suffice.
The inlet valve eccentric is connected by an eccentric strap and rod to a crank-
arm on a rock shaft journalled in bearings formed in one of the removable heads.
Splined upon and secured to the rock-shaft is an oscillating part or pusher.
The pusher is provided with a wearing surface, which is preferably located
with an angular lead with reference to the rock-shaft, and co-operates with a
vertically movable tappet mounted in an attachment on the inlet valve-stem.
The inlet valve-stem extends from the removable shell or plug through a
suitable stuffing box, and is adjustably threaded at its end into the attachment
or casting which carries the vertically movable tappet.
The vertically movable tappet is preferably provided with a wearing surface
of hardened steel, to co-operate with the oscillating pusher, and has a curved
arm or finger, which extends downwardly to engage with governor-controlled
connections for regulating its height, the point of contact being substantially
normally in the line of the vertical axis of the tappet.
The governor may be of any ordinary or preferred pattern, and by means of a
bell-crank lever, actuates a reciprocating rod, which extends below the removable
heads.
Journalled upon the reciprocating rod, in position to engage with the down-
wardly extending finger of the tappet is a conical roller.
The conical roller is secured in place by means of an adjustable bracket having
at one end an upwardly extending cam-plate or projection, which is adapted to
engage with and actuate the vertically movable tappet, in case the governor
becomes broken or fails to act, thus forming a safety device.
By providing the reciprocating rod with a conical roller to engage with and
actuate the vertically movable tappet, the friction, which will oppose the transverse
motion of the tappet, is decreased, and, as the governor connections act sub-
stantially concentrically upon the vertically movable tappet, the tendency of the
tappet to cramp or bind, as it is moved up and down, is avoided.
It is to be noted that, as the wearing surface of the oscillating pusher is
located eccentrically, or off the centre with respect to its rock-shaft, it will move
down a greater distance for the same amount of angular movement than it would

page_text: if said wearing surface were arranged directly over and in line with the rock-
shaft.
By means of this construction, the pusher may lap a greater distance upon the
tappet, and an increased wearing surface for the parts is thus provided, forming
a more durable construction than has heretofore been employed.
The dash-pot for closing the inlet valve is preferably located in line with the
valve-stem, so that it may act positively and directly, without intervention of
intermediate mechanism.
The piston-rod from the dash-pot is threaded into the attachment or casting
which carries the vertically movable tappet.
It will be seen that independent means of adjustment are provided between
the inlet valve and its movable tappet, and between the movable tappet and the
dash-pot.
This is an advantageous feature in practice.
If it is desired to give the inlet valve a greater or less lap. the same can be
done by adjusting the inlet valve-stem, without affecting the action of the cut-off
mechanism or of the dash-pot.
Also, if it is desired to have the dash-pot act more or less strongly, the same
can be adjusted by means of its piston-rod, and the connection before described,
without affecting the point of cut-off or the position of the inlet valve.
In connection with the valve-gear for operating the inlet valve, as before
described, any suitable mechanism may be employed for operating the outlet
valve.
The preferred construction comprises a toggle joint, which is directly actuated
by the outlet valve eccentric.
The outlet valve-stem extends through a suitable stuffing box, and is connected
to one of the toggle links or levers.
A second toggle link or lever is piroted to the first link and to a block carried
by the removable head.
Power for actuating the outlet valve through this toggle joint is applied to
the toggle levers from the outlet valve eccentric by means of an eccentric strap
and an eccentric rod.
This arrangement of toggle links or levers for operating the outlet valve is a
desirable construction, as the valve will be given a quick opening and closing
movement.
It is also to be noted that by using an eccentric to actuate the toggle, more
or less motion is always being imparted to the valve, and as the valve is never
brought to entire rest upon its seat, its tendency to become stuck or clogged is
greatly diminished.
Numerous changes may be made by skilful mechanics in constructing engines
according to this invention, and certain of the features of construction, as herein
described, may be employed in different locations and in different combinations.

For the Applicant.
Improvements in Steam Engines.
I JOSHUA ENTWISLE, Manager with the Firm of E. K. Dutton & Co.,
50 Chartered Patent Agents, of 5 John Dalton Street, Manchester, in the County of
Lancaster, do hereby declare the nature of this invention (communicated to me
from abroad by Edward Kittredge Hill of Worcester City, in the County of

page_text: Worcester, Massachusetts, in the United States of America, Manufacturer and
Joseph Hinson Webster Hoadley of Chicago, Cook County Illinois, United
States of America, Manufacturer,) and in what manner the same is to he
performed to be particularly described and ascertained in and by the following
statement and accompanying drawings :-
-
The object of this invention is to provide a steam engine in which the working
parts are arranged in an efficient, convenient and compact manner, and are capable
of simple and convenient adjustments; the working parts being so mounted that
friction may be reduced to a minimum, and the engine rendered capable of
extremely accurate regulation.
To these ends, this invention consists in the parts and combinations of parts, as
hereinafter described, and more particularly pointed out in the claims at the end of
this Specification.
In the accompanying five sheets of drawings,
Fig. 1 is a top plan view of an engine constructed according to this invention,
Fig. 2 is a side elevation of the same,
Fig. 3 is an enlarged view, partially broken away, of the cylinder and valve-
operating mechanism,
Fig. 4 is a transverse sectional view of the cylinder taken through the inlet
valve,
Fig. 5 is a similar view taken through the outlet valvė,
Fig. 6 is a detail view of the valve gear for operating the inlet valve, showing
the parts in a different relative position from that shown in Fig. 4,
Fig. 7 is a detail view of the valve gear for operating the outlet valve, showing
the parts in a different relative position from that shown in Fig. 5, and
Figs. 8 to 12 inclusive are detail views to be hereinafter referred to.
Referring to the drawings and in detail, A designates the cylinder casting, which
is provided with a steam chest or steam passage a, to which steam may be admitted
by means of a throttle valve as d, the casting being also provided with suitable
outlet passages, as indicated at b.
B designates the bed piece or frame, and C a pillow-block, which forms a
bearing for the main shaft D.
These parts may be of the ordinary or approved construction, and the drawings
illustrate a construction embodying features which are ordinarily employed in what
is known as the Wheelock engine, although it is evident that the parts, as
hereinafter described, may be used in connection with any engine to which they are
found to be applicable.
A removable shell or plug 10 is fitted into each end of the cylinder casting, and
is preferably held in place by means of a washer or bonnet 19, and a securing
nut 20, as shown in Figs. 4 and 5.
Each of the plugs 10 is provided with suitable transverse bearing-strips or
surfaces 13, 14 and 15, which are arranged to co-operate with and fit tightly against
the bearing surfaces 10, 17 and 18 formed in the cylinder casting.
Mounted in each of the movable shells or plugs is a sliding gridiron inlet
valve 11 and an outlet valve 12. These valves are arranged to work trausversely
of the cylinder, and to co-operate with suitable valve-seats, which are formed with
the plug.
In the actual use of plugs or shells, which are provided with seats for the inlet
and outlet valves, it has been found that the pressure of the steam acting against
the inlet valve and the inlet valve-seat is apt to strain the inlet valve-seat so as to
prevent the bearing surface 15 of the plug from fitting tightly against the bearing
surface 18 of the cylinder casting, thus producing leakage between the surfaces 15
and 18, and seriously interfering with the efficiency of the engine.
To overcome this difficulty, the removable shell or plug is provided with braces
or struts as 21, which are secured above the outlet valve, and are adapted to
re-enforce and stiffen the inlet valve-seat.
Referring to Figs. 8 and 9, 21 designates, the re-enforcing braces, which are

page_text: constructed with suitable side-bars or pieces connected by cross pieces 210 forming
a ladder or grating, which will stiffen the inlet valve-seat in such a way as to
prevent the possibility of leakage about the plug.
It sometimes happens in the use of steam engines that an abnormal pressure may
be created in the cylinder from the presence of water, and from this cause, the
cylinder-head may be blown out, or parts of the engine may be broken.
To overcome this difficulty, it is desirable to have the inlet valve held against its
seat by means of spring tension, so that in the case of abnormal pressure in the
cylinder, the inlet valve may he forced from its seat, and the pressure relieved.
To allow for this action, the shells or plugs 10 are provided with a transverse
cut or slot, as most clearly shown in Fig. 8.
Fitting into this cut-away section of the plug is a piece or section 22, which may
be secured in place, and may be finished with a plug so that the said piece 22 will
conform to and have the same curvature as the surface of the plug.
The piece 22 is made in the form of a grating, as most clearly shown on an
enlarged scale in Fig. 10, the side pieces of the grating being provided with
suitable sockets or cut-away portions, within which are arranged springs 24, which
act upon suitable followers or contact shoes 23, which are adapted to engage with
the inlet valve, and hold the same upon its seat with spring tension.
When the removable plug or shell is driven or fitted into its place in the cylinder
casting, the piece 22 will be held in position between the plug itself and the
bearing surfaces of the cylinder casting, and by means of this construction, efficient
and simple means are provided for holding the inlet valve upon its seat.
This is an advantageous construction, as, if either spring should break, none of
the pieces will drop into the valve and interfere with the operation thereof.
Upon the end of each removable plug or shell is a removable head, which is
detachably secured to said plug, and is adapted to support and form a bearing for
the valve-operating mechanism, as hereinafter described.
In practice, this is a desirable feature of construction, as the valve-operating
mechanism may be finished independently of the plug itself, and, as substantially
the same valve-operating mechanism may serve for several different sizes of engines,
the heads can be finished and completed in quantities, thus cheapening and
simplifying the construction of the engine.
The mechanism preferably employed for actuating the valves may be described
as follows:
A gear or pinion 26 secured upon the main shaft D meshes with and drives a
pinion 27, which has a bevel-gear or pinion 28 fastened to and turning therewith.
The bevel-gear 28 in turn meshes with and drives a bevel-gear 29, which is secured
upon a shaft 30, which is journalled in suitable brac ets, which may be fastened to
the bed-piece of the engine, as shown.
Near the centre of the shaft 30, we provide suitable gearing for driving the
governor of the engine, this gearing preferably being enclosed within a casing 31.
As this gearing consists merely of the ordinary bevel-pinions, it need not be
herein shown or described at length.
A valve-actuating shaft 36 is journalled in suitable boxes secured to the cylinder,
as shown, and a universal joint and a clutch, as illustrated at 32, is preferably
employed for connecting the shaft 36 with the shaft 30.
The clutch illustrated in the drawings is of the ordinary two-part pattern,
which is provided with a section 33, and a corresponding, movable section 330,
which can be actuated by means of a handle 34, which is suitably pivoted
as at 35.
When the clutch is disconnected, the valve-actuating shaft 36 is free to rotate
independently, and, as shown in the drawings, the same is provided with a suitable
capstan head, as shown at E, by means of which it can be rotated by hand, and the
valves of the engine thus actuated.
The use of a universal joint for connecting the valve actuating shaft with the
driven shaft, has been found to be a desirable arrangement, as by means of this

page_text: construction, the same mechanism for actuating the valves can be used in different
sizes of engines, and the valve-actuating shaft can be conveniently coupled to and
driven from the main shaft of the engine, independently of the relative position of
the valve-actuating shaft to the main shaft.
Mounted upon and secured rigidly near each end of the valve-actuating shaft 36
are suitable collars 37, having face-plates 38 and 39, as shown.
Also mounted on the valve-actuating shaft 36, in a position to be detachably
secured to the face-plates, are eccentric disks for actuating the valves of the engine,
and as the valve gears for actuating the valves at each end of the cylinder are
duplicates of each other, a description of oue set of valves and its connections
will suffice.
For the purpose of adjustably securing the valve-operating eccentrics in position
upon the face-plates, each of the eccentric disks is preferably provided with a
bolt 42, which fits through a slot 420 formed in the face-plate, and is secured
iu position by means of a clamping nut, as shown most clearly in Figs. 4 and 6.
a
44 designates an eccentric strap for actuating the inlet valve, which is connected
to and moves an eccentric-rod 45, which is pivoted to a crank arm 46 carried by
rock-shaft 47, which is journalled in suitable bearings formed in a downwardly
extending projection of the removable heads.
Splined upon and secured to the shaft 47 is an oscillating part or pusher 48,
which also has a set-screw 48 for insuring a rigid connection between the same and
the rock-shaft 47.
The part or pusher 48 is provided with a wearing surface 50, which may be held
in place by screws, and which is preferably formed of hardened steel, to co-operate
with a vertically movable tappet carried by the inlet valve-stem.
The wearing surface of the oscillating pusher 48 is preferably located with
an angular lead with reference to the rock-shaft 47, for a purpose hereafter
described.
51 designates the inlet valve-stem, which extends from the removable shell or
plug 10, through a suitable stuffing-box 52, and is threaded at its end into a split
bearing formed in the casting 53.
To secure the valve-stem 51 tightly in its adjusted position in the casting 53 is a
suitable pinch-nut 54.
A vertically movable tappet 55, which has a steel wearing-plate 56 secured as
by screws thereto, in position to co-operate with the pusher 48, is mounted in the.
casting 53, and is provided with a curved arın or finger 57, which extends down-
wardly, engaging with a governor-controlled device for regulating its height, the
point of contact being substantially normally in the line of the vertical axis of the
tappet 55.
The governor connections, which are preferably employed, may be arranged
as follows:-
58 designates the governor of the ordinary pattern, which actuates a bell-crank
lever 59, which is connected to reciprocate a rod 60 extending below the removable
heads, as most clearly shown in Figs. 1 and 3.
In order to oppose as little friction as possible to the action of the governor, the
bearings 61 of the shaft 60 are provided with suitable friction-rolls 62 and 63, as
shown in dotted lines in Fig. 3.
Journalled upon the rod 60 in a position to engage a foot-piece 570 carried by
the downwardly extending finger 57 of the tappet 55 is a conical roll 64.
The roll 64 is secured in place upon the reciprocating governor-rod 60 by means
of a bracket 65, which is adjustably clamped to the governor-rod by means of a
pinch-bolt 650.
The bracket 65 is provided at one end with an upwardly extending cam-shaped
projection 66, which is adapted to engage with and actuate the vertically movable
tappet 55, in case the governor becomes broken or fails to act, thus forming a safety
device, which acts in a well known manner.
By providing the reciprocating governor-rod 60 with the conical rollers 64 to

page_text: engage with and actuate the vertically movable tappets, the friction which will
oppose the tappet when the same is moved transversely by means of the oscillating
pusher is decreased, and, in practice, this forms a very efficient and desirable forin
of governor connection, and, as the governor connections act substantially concen-
trically upon the vertically movable tappets, the tendency of the tappets to cramp.
or bind, as they are moved up or down, is entirely avoided.
As before stated, the projection of the oscillating pusher 48, which engages with
and actuates the tappet 49, is preferably offset or set with angular lead with
reference to the rock-shaft 47, as most clearly shown in Fig. 6.
The object of this construction is to increase the surface of contact between the
tappet and the pusher.
It is to be noted that as the contact surface of the pusher 48 is located some.
distance to the left of the centre of the rock-shaft 47, as shown in Fig. 6, the same
will move downward a greater distance for the same amount of angular movement
that it would if said wearing surface were arranged directly over and in line with.
the rock-shaft 47.
By means of this construction, the pusher may be allowed to lap a greater
distance upon the tappet, and an increased wearing surface for the parts is provided
so that the same will not wear out so quickly, as in constructions as heretofore
arranged.
Inasmuch as the valve-stem 51 of the inlet valve extends through only one head
of the removable plug or shell 10, the unbalanced pressure of steam upon the
valve 12 will always have a tendency to hold the inlet valve in its closed position,
but to ensure the closing of the valve promptly and accurately, a dash-pot is
ordinarily provided, and this dash-pot is preferably located in line with the valve-
stem, so that the same may act positively and directly without the intervention of
any intermediate mechanism.
°
As shown most clearly in Figs. 4 and 6, 67 designates a piston-rod having a.
piston 69 secured thereto, which fits into a suitable dash-pot 71, and is engaged by
a suitable coiled spring 70, as shown.
The dash-pot, as thus constructed, is provided with a small orifice, which may be
regulated by means of a tap-bolt 72 in any of the well known manners.
At its opposite end, the piston-rod 57 is threaded into a split bearing formed in
the casting 53, heretofore described, and a pinch-bolt 68 is provided for rigidly.
securing the piston-rod in its adjusted position.
This independent connection of the valve-stem and the piston-rod into the
casting 53 is an advantageous feature in practice, for if it is desired to give the
valve a greater or less lap, the same can be easily done by adjusting the rod 51
without affecting the action of the cut-off mechanism or the action of the dash-pot
mechanism, or again, if it is desired to have the dash-pot mechanism act more or
less strongly, the same can be adjusted by means of the piston-rod 67 and the
connection before described without affecting the point of cut-off, cr the position of
the valve.
:
This provides a simple and efficient means of adjustment for regulating the action
of the valve.
In connection with the valve-gear for operating the inlet valve, as before
described, any suitable form of mechanism for operating the outlet valve may be
employed, but the arrangement preferably employed, is most clearly shown in
Figs. 5 and 7.
Referring to these figures, 73 designates the outlet valve-stem, which extends
from the plug or shell 10 through a suitable stuffing-box 74, and is provided at its
outer end with a bearing 75 in the head 25.
Links or levers 76 are pivoted to a fixed point or block 760, and links or levers 77
are pivoted to a casting 78 secured upon the outlet valve-stem by means of the
nut 780 threaded on the valve-stem, as shown.
At their opposite ends, the links or levers 76 and 77 are pivoted to a suitable
head or casting 79, and by means of this construction, it will be seen that the

page_text: links 76 and 77 form substantially a toggle joint, by means of which the outlet
valve may be positively moved in either direction.
Power for actuating the outlet valve through this toggle joint is applied to the
toggle levers through the eccentric-rod .80 and the eccentric-strap 81.
In practice, it has been found that an arrangement of toggle links or levers for
actuating a steam engine valve is a very desirable arrangement, as with the same,
the valve will have a quick opening and closing movement.
It is also to be noted that by using an eccentric to actuate the toggle, more or
less motion is always being imparted to the valve, and, as the same is never brought
to entire rest upon its valve-seat, the tendency for the same to become stuck or
clogged is greatly diminished.
This valve-oporating mechanism may be employed in connection with any valve
to which it is desired to impart a similar movement, and the use of this mechanism
is not necessarily limited to an outlet valve.
It is further to be noted that by applying power to the joint of the toggle, the
power is applied in a position to secure the greatest leverage, and to most easily
overcome the resistance of the valve.
It will be noted that in an engine constructed according to this invention, an
eccentric is provided to operate each valve of the engine, and each eccentric is
adjustable.
This is an important feature, as each valve (can be independently set and
adjusted.
Numerous changes can be made in the engines constructed according to this
invention, and certain of the parts can be used in different locations and in different
combinations without departing from the scope of the invention, as expressed in
the claims.
