[Communicated from abroad by WILLIAM EDWARD KELLY, of No. 65, George Street,
New Brunswick, New Jersey, United States of America, Manufacturer.]
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention to be as follows: :-
My invention relates to a steam generator in which a number of tubes are arranged
upon an incline and subjected to the heat from a furnace. Water circulates through
these tubes, which are connected at their ends to headers, and the headers are united
one above another and connected with a steam and water drum into which the water,
when sufficiently beated, and steam will ascend. The cooler water will descend from
the drum to the lower end of the inclined tubes, whereby a continuous circulation is
kept up. Each of the headers may have one or more of the circulating tubes connected
to it.
The said invention consists first in a combined header and saddle placed under the
forward end of the steam and water drum and affording communication between the
inclined tubes and the drum. This saddle is cast hollow, and provided with a conduit
which is closed against the admission of steam or water from the saddle. This conduit
may be cast in the saddle.
A pipe secured in a suitable opening in the conduit affords communication between
the latter and the interior of the drum. Another pipe secured in another opening in
the conduit extends outwardly and connects near its outer end with a water gauge
column. The upper end of the water gauge column communicates by means of a
pipe with a conduit in a nozzle or nipple for a safety valve, or other suitable outlet

page_text: nozzle, which conduit is likewise closed to the interior of the nozzle.
conduit extends another pipe into the steam space of the drum.
From this
The said invention further consists in another conduit in the saddle similar to the
one previously referred to, with which communicate feed water pipes by which water
is supplied to the interior of the drum.
The invention also partly consists in providing the nozzle or nipple for the safety
valve, or other outlet nozzle, with a conduit closed to the interior of the nozzle
from which extends a pipe to the interior of the drum, and another pipe to a steam
gauge.
The invention also partly consists in a saddle similar to the one referred to but
located at the rear of the drum. This saddle affords communication with the inclined
tubes for the return water, and is provided with two conduits similar to those described
in the other saddle with which connect pipes from a scum-collector and blow-off pan
within the drum, and also other pipes leading to the outside of the generator through
which scum may be blown off.
An important feature of my invention consists in the flame plates by which the
products of combustion are caused to follow a circuitous course through the inclined
circulating tubes. These flame plates are made up of sections. Each of these sections
is undivided and has one or more of the circulating tubes extending through it, and
when the sections are in place, they form a continuous flame plate, the sections being
superposed one upon the other. Each of the sections is the same shape as the headers
to which the circulating pipe or pipes which extend through such section are secured.
The sections are made of iron and are hollow. They will preferably be cast in such
manner that they will have a back, a rim extending about the edges, and thimbles
formed in suitable positions in the back and extending forward approximately coincident
with the rim. Pins or projections extend from the back toward the front of the
sections. These pins are preferably arranged at inclines to each other, and may be
cast with the sections or secured therein in any suitable manner.
The spaces within
the hollow sections are filled with fire clay or other material. The pins serve to retain
the fire clay in position when such is used. The sections of the flame plates may be
secured together at their backs by means of pins or bolts passing through lugs on the
sections.
Another feature of my invention consists in the form of the channel irons above
the drum and the arrangement of the hooks by which the drum is supported from the
channel irons. The channel irons have flanges upon their lower sides which extend
inwardly or toward each other, whereby a considerable space is left between the
channel irons. I employ but a single hook with each pair of channel irons, which
hook is accommodated within the space between the channel irons. The hooks engage
with iron loops rivetted to the drum.

Still another feature of my invention consists in the headers, to which the inclined
tubes are connected. For closing such headers I employ a cup or cover having
bearing against the inner surface or side of the header, in which is arranged the
opening to be closed. The means for securing the cap or cover in place forces the
latter outwardly, while its thrust is sustained in rear of the cap or cover.
pressure forcing or tending to force the cap or cover outwardly, acts to tighten, rather
than loosen, the joint. In one example of this part of my invention each of the
headers is approximately triangular but has the lower portion of the sides chamfered
off vertically, the upper portions of the sides extending vertically and a flat top.
Any desired number of these headers may be suitably arranged and connected
together by intermediate nipples, secured in openings of the headers, water will flow
from one header to another through the connecting nipple. Each of the headers in
this example of my invention has three holes or openings for the reception of circulating
tubes. Each of them also has in the front a hand hole or opening of approximately
triangular shape but the corners will preferably be rounded. This opening is closed
by a cap or cover, which is the same shape as the opening only slightly larger_and
will preferably be provided with a rib upon one side extending about it inwards from

page_text: the edge. This cap or cover is inserted edgewise through the opening, and then
adjusted into place by the aid of handles with which it is provided, so that its rib will
fit the edge of the opening, and its portion which extends beyond the rib will fit
against the back of that wall or side of the header in which the front opening is
arranged. The cap is secured in place by means of a screw. In this example of my
invention the screw has an end bearing in the back of the header and can rotate in
this bearing. It passes through the cap or cover and engages with a screw thread
formed in the same. By engaging the cap or cover with the screw fitting the latter
in its bearing and rotating it, the cap or cover may be forced outwardly to its place.
A jam nut may be applied to the screw outside the cap or cover.

page_text: I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 :-
My invention relates to improvements in steam generators of the Babcock and
Willcox type in which are a number of tubes arranged upon an incline and
subjected to the heat from a furnace. Water circulates through these tubes, which
are connected at their ends to headers and the headers are united one above the
other and connected with a steam and water drum into which the water, when
sufficiently heated, and steam will ascend. The cooler water will descend from the
drum to the lower end of the inclined tubes whereby a continuous circulation
is kept up. Each of the headers may have one or more of the circulating tubes
connected to it.
The invention consists first in a combined header and saddle placed under the
forward end of the steam and water drum and affording communication between the
inclined tubes and the drum. The saddle is cast hollow, and is provided with a
conduit which is closed against the admission of steam or water from the saddle.
This conduit may be cast in the saddle. A pipe secured in a suitable opening in the
conduit affords communication between the latter and the interior of the drum.
Another pipe secured in another opening in the conduit extends outwardly and
connects near its outer end with a water gauge column. The upper end of the water
gauge column communicates by means of a pipe with a conduit in a nozzle or nipple
for a safety valve, or other suitable outlet nozzle, which conduit is likewise closed to
the interior of the nozzle. From this conduit extends another pipe into the steam
space of the drum.
The invention, further consists in another conduit in the saddle, similar to the one
previously referred to, with which communicate feed water pipes by which water is
supplied to the interior of the drum.
The invention also consists in providing the nozzle or nipple for the safety
valve, or other outlet nozzle, with a conduit closed to the interior of the nozzle, from
which extends a pipe to the interior of the drum and another pipe to a steam gauge.
The invention also consists in a saddle similar to the one referred to but located at
the rear of the drum. This saddle affords communication with the inclined tubes for
the return water and is provided with two conduits similar to those described in the
other saddle, with which connect pipes from a scum collector and blow-off pan within
the drum, and also other pipes leading to the outside of the generator through which
scum may be blown off.
An important feature of my invention consists in the flame plates by which the
products of combustion are caused to follow a circuitous course through the inclined
circulating tubes. These flame plates are made up of sections. Each of these sections
is undivided and has one or more of the circulating tubes extending through it, and
when the sections are in place they form a continuous flame plate, the sections being

page_text: superposed, one upon the other. Each of the sections is the same shape as the headers
to which the circulating pipe or pipes which extend through such section, are secured.
The sections are made of iron and are hollow. They will preferably be cast in such
manner that they will have a back, a rim extending about the edges and thimbles
formed in suitable positions in the back and extending forward approximately
coincident with the rim. Pins or projections extend from the back toward the front
of the sections. These pins are preferably arranged at inclines to each other, and may
be cast with the sections or secured therein in any suitable manner.
The spaces
within the hollow sections are filled with fire clay or other material. The pins serve
to retain the fire clay in position when such is used. The sections of the flame plates
may be secured together at their backs by means of pins or bolts passing through lugs
on the sections.
Another feature of my invention consists in the form of the channel irons above
the drum and the arrangement of the hooks by which the drum is supported from the
channel irons. The channel irons have flanges upon their lower sides, which extend
inwardly or toward each other, whereby a considerable space is left between the
channel irons. I employ but a single hook with each pair of channel irons, which
hook is accommodated within the space between the channel irons. The hooks
engage with iron loops riveted to the drum.
Still another feature of my invention consists in the headers to which the inclined
tubes are connected. For closing such headers I employ a cap or cover having a
bearing against the inner surface or side of the header in which is arranged the
opening to be closed. The means for securing the cap or cover in place, forces the
latter outwardly while its thrust is sustained in rear of the cap or cover. Steam
pressure forcing or tending to force the cap or cover outwardly acts to tighten rather
than loosen the joint. In one example of this part of my invention, each of the
headers is approximately triangular, but has the lower portion of the sides chamfered
off vertically; the upper portions of the sides extending vertically and a flat top.
Any desired number of these headers may be suitably arranged and connected
together by intermediate nipples secured in openings of the headers. Water will
flow from one header to another through the connecting nipple. Each of the headers
in this example of my invention has three holes or openings for the reception of
circulating tubes. Each of them also has in the front a hand hole or opening of
approximately triangular shape, but the corners will preferably be rounded. This
opening is closed by a cap or cover which the same shape as the opening only
slightly larger, and will preferably be provided with a rib upon one sido extending
about it inwards from the edge. This cap or cover is inserted edgewise through the
opening and then adjusted into place by the aid of handles with which it is provided
so that its rib will fit the edge of the opening and its portion which extends beyond
the rib will fit against the back of that wall or side of the header in which the front

opening is arranged. The cap is secured in place by means of a screw.
example of my invention the screw has an end hearing in the back of the header.
It can rotate in this bearing. It passes through the cap or cover and engages with a
screw thread formed in the same. By engaging the cap or cover with the screw,
fitting the latter in its bearing and rotating it, the cap or cover may be forced out-
wardly to its place. A jam nut may be applied to the screw outside the cap
or cover.

is a front view of a sinuous header embodying my improvement.
Similar letters of reference designate corresponding parts in all the figures.
I will first describe generally the steam generator which I have shown in Figure 1,
to illustrate the various features of my improvement, premising, however, that said
improvements are not confined in their application to steam generators of this style.
A designates a number of tubes which are arranged upon an incline and subjected
to the influence of the heat of the products of combustion from a furnace. These
tubes are connected at their ends to headers B, and the headers B are united one
above another, and connected with a steam and water drum, C, so that water, when
sufficiently heated, and steam may ascend through the inclined tubes, and rise through
headers B, to which the upper ends of the inclined tubes are connected, into the
drum C, and so that the cooler water will descend from the drum C, into and through
the headers to which the lower ends of the inclined tubes are connected, and pass
from these headers into the inclined tubes.
D designates a combined header and saddle placed under the forward end of the
steam and water drum C, and affording a means of communication between the
inclined tubes and the drum. This saddle will be cast hollow, and preferably provided,

page_text: for the purpose of increasing its strength, with vertical partitions a, dividing it into
compartments, communication between the compartments being afforded by means of
openings in the partitions. The upper row of headers B communicates with the
saddle D by means of nipples e expanded or screwed into openings d in the lower side
of the saddle D and into corresponding openings in the upper sides of the headers.
The saddle is provided with a curved flanged portion d', upon which the drum
rests, and which is riveted to the drum. An opening in the drum affords com-
munication between the drum and the saddles. The saddle is provided with a
conduit D' which is closed against the admission of steam or water from the saddle.
This conduit may be cast in the saddle. A pipe D² secured near one end in a suitable
opening in the conduit D', affords communication between the conduit and the interior
of the drum. A pipe D³ secured at one end in a suitable opening in the conduit DI
below the drum extends outwardly, and connects near its outer end to the lower end
of a water gage column D. The upper end of the water gage column D* communicates
with a nozzle or nipple, Do, for a safety valve D6, by means of a pipe D'. Within
the nozzle D is formed a conduit e (shown more clearly in Figures 11, 12, 13, 14, 15
and 16) with which the pipe D' communicates and with which there is also connected
a pipe Ds extending into the steam space of the drum. Water is supplied to the water
gage column from the pipe D3, which latter, it will be observed, extends well away
from the point where the saddle communicates with the drum, and hence to a point
where the water is less agitated than near the opening.
D designates a conduit similar to the conduit D₁, and likewise arranged in the
saddle D. Feed-water pipes D¹ D" communicate with this conduit, whereby water
may be fed to the drum. It is an important feature of this arrangement that I am
not obliged to cut holes in the shell of the drum C in order to introduce any of the
pipes for the water-gage or the feed-water pipe. The cutting of such holes is very
difficult of execution and can seldom be done with a desired degree of accuracy, and
also has a tendency to weaken the shell of the drum. By providing the saddle D and
nozzle D, therefore, with closed conduits, with which the pipes of the water gage and
feed-water pipe communicate, much time and labor are saved because the conduits
may be cast in the saddle and nozzle and the holes for the reception of the pipes
may be tapped before the saddle and nozzle are secured to the drum.
:
I do not wish to be understood as limiting myself to the precise shape of the
conduits D and e, nor to the particular manner of connecting the several pipes
thereto, as these may of course be varied. Figures 14, 15 and 16 illustrate different
methods of forming the conduits e in the nozzle D, and like modifications of form
or even different ones may be employed in the saddle.
In Figures 1, 11 and 12 I have shown a means of affording communication between
the interior of the drum and a steam pressure gage, E, without cutting a hole
through the shell of the drum, consisting in a pipe E', communicating at one end
with the steam-gage, and at the other with a conduit e' in the nozzle 1), similar to
the conduit e. A pipe e extends from the conduit e¹ into the interior of the drum.
F designates a saddle somewhat similar to the saddle D, located beneath and near the
rear end of the drum and riveted to the drum. This saddle affords communication
with the circulating tubes A for the returning water, tubes f being connected to it
and the headers B at the lower end of the inclined tubes A. This saddle is provided,
as shown, with two conduits f¹, similar to the conduits D', with which pipes from
a scum-collector and blow-off pan f³, communicate. Pipes f' also connect with the
conduits and extend outside the generator, through which scum may be blown off.
Of course, feed-water pipes can be introduced into the saddle F, if desirable. By
riveting the saddles D and F to the drum the latter is braced and strengthened.
Another important feature of my improvement consists in the flame plates K K¹,
by which the flame and products of combustion are caused to follow a circuitous
course through the circulating tubes. These flame plates are made up of sections G,
which will preferably conform to the form of the headers B each of which headers is
shown in this example of my improvement as receiving three of the circulating tubes.
I have shown this arrangement more clearly in Figure 8; but I do not wish to be

page_text: understood but that other forms of headers and flame-plates may be used than those
shown. The sections G of the flame-plates are made of iron and are hollow. They
will preferably be cast in such manner that they will each have a back g, a rim g',
extending about the edges and thimbles g² formed in suitable positions in the back
and extending forward approximately coincident with the rim g'. Pins or pro-
jections g³ extend from the back toward the front of the sections. As shown they are
arranged at inclines to each other. They may be cast with the sections or secured
therein in any suitable manner. It is intended that the space within the sections
shall be filled with fire-clay or similar materials. Where such material is used the
pins gå serve to retain it in position. I may however, fill in the spaces with bricks
of suitable form which may be driven in or secured therein in any suitable manner.
In such case the pins might be omitted. So far as the pins gl and their arrangement
are concerned, the flame-plates might of course be of any desired form. The sections
are provided upon their rear sides with lugs 9, through which pins or bolts 9³ may be
passed to secure them together when in position about the pipes. The circulating-
tubes extend through the thimbles g², which latter protect the clay within the sections
from the rubbing of the tubes. It will be advantageous to place the flame-plate
sections in position on the tubes as shown in Figure 8, before shipment, and fill them
with the clay or other material when the generator is being erected. The heat of
the furnace may then be depended on to bake the clay hard. The sections are
superposed one upon the other, and do not overlap.
In Figure 10, I have shown a flame-plate section of modified form, composed of a
number of parts, s¹, secured together and held in place by bolts. Although this
flame-plate is made up of a number of parts, it is undivided, said parts being con-
nected rigidly together, so as not to be capable of separating or dividing when in use.
Flame plates made according to my improvement are cheap, desirable, will not warp,
and are easily placed in position.
Another feature of my improvement consists in the channel-irons J above the
drum, and the mode of arranging the hooks by which the drum is supported from
the channel-irons. The channel-irons, it will be observed, have flanges upon their
lower sides, which extend inwardly or toward each other, whereby a considerable
space is left between the channel-irons. By thus forming the channel-irons I am
enabled to use but a single hook, J¹, with cach set of channel-irons, which hook is
enclosed within the space between the channel-irons, thereby enabling the channel-
irons to be brought much closer to the drum, than has heretofore been possible when
single hooks have been used. The hooks J'engage with iron loops J³, riveted to the
drum. The height of the generator is therefore materially reduced, which is a
desirable feature.
Instead of the conduits e e¹ being arranged in a safety-valve, they may be arranged
in any other suitable outlet-nozzle.
I will now particularly describe the various examples of headers with the appur-
tenances thereof which I have shown.
Referring first to Figures 17 and 18, B designates headers, each of which is
approximately triangular, but has the lower portions of the sides chamfered off
vertically, the upper portions of the sides extended vertically, and a flat top. I have
in this figure shown four of these headers connected together one above the other by
intermediate nipples c, which will preferably be secured in the openings of the
headers in which they fit by expanding them into such openings. Water will flow
from one header to another arranged above or below it through the connecting
nipple. Any desirable number of the headers may of course be similarly arranged and
connected.
In Figure 19, I have shown that headers, such as I have illustrated in Figures 17
and 18, arranged one above another, may be cast integral, so as to form one structure.
Any desirable number of headers may be cast together in this manner.
Each of the headers shown in Figures 7 and 19 has three holes or openings, ¹² 3,
for the reception of tubes A such as I have illustrated in Fig. 1. Each of these
headers has in front a hand-hole or opening, 4, of approximately triangular shape;

page_text: but the corners will preferably be rounded. This opening is closed by a cap or
cover, B', which is of the same shape as the opening 6 only slightly larger and is
preferably provided with a rib 6. This cap or cover is inserted edgewise through
the opening 4, and then adjusted into place by the aid of bandles 6, with which it is
furnished, so that its rib will fit the edge of the opening, and its portion which
extends beyond the rib will fit against the back of that wall or side of the header in
which the opening is arranged. A packing of soft suitable material may be inter-
posed between the edge portion of the cap and the rear surface of the front of the
header.
The cap or cover B¹ is secured in place by means of a screw B², whereby it is forced
outward. In Figure 18, this screw is shown as having an end bearing in the back of
the header. It can rotate in this bearing. It passes through the cap or cover B¹,
and engages with a screw thread which is formed in the cap or cover. By engaging
the cap or cover with the screw, fitting the latter in its bearing and rotating it, the
cap or cover may be forced outwardly to its place. A jam-nut E³, may be applied to
the screw outside the cap or cover.
I have shown in Figure 20 that, instead of forming a screw-thread in the cap or
cover, I may fit in the cap or cover an internally screw-threaded bushing S, for
engaging with the screw. The bushing must be shaped externally so that it will not
turn in the cap or cover. It will be observed that the rear portion of the screw is
smaller in diameter than the forward part, where the screw-thread is located. This
reduces the liability of incrustations on the screw interfering with the adjustment of
the cap or cover. It also expedites the moving of the cap or cover to its place,
because the cap or cover, when the screw is thus made, does not need to be adjusted
along an unnecessary length of screw-thread.
In Figure 21, the screw B³ has a right-hand screw-thread at one end and a left-
hand thread at the other. One end is inserted in a tapped hole in the back of the
header and the other end engages with a nut G, which is fitted into the cap or
cover B'. This nut has a polygonal boss, to which a wrench may be fitted for the

or cover will be forced outwardly. A packing may be used around the nut, if
desirable. Of course I may use a second nut upon the nut G, to clamp against the
outer side of the cap or cover.
Figure 22 illustrates that a screw B³ may be made to turn loosely in the cap or
cover without engaging therewith, and to screw into a tapped socket, o, in the rear
wall of the header. This socket, o, will preferably be extended rearward, so as not
to interfere with a free flow of water through the header. A jam-nut, E³, may be
applied to the outer end of the screw and bear against the outer surface of the cap or
cover.
Figures 23 and 24 show that a header such as I have described may have one
elliptical hand-hole 67, and one circular hand-hole 8, instead of a single large
triangular hand-hole. The two hand-holes will have caps or covers B¹ of correspond-
ing shapes combined with them. The cap or cover for the small hand-hole will be
inserted through the large hand-hole. It will then be engaged with the screw B²
whereby it is to be secured in place. The screw B2 in this case, has a bearing in a
tripod B³, which bears against the rear wall of the header, and is centered by one of
the tubes A. The tripod may indeed be made resilient and then can be made to hug
the end of the tube so as to remain in place. It is not intended to rotate. The
screw B2 will be rotated after engagement with the tripod to force the cap or cover
with which it engages outwardly to its place. A jam-nut, E³, may be combined with
the outer end of the screw. The cap or cover for the large elliptical hand-hole will
be afterwards inserted in the header and forced to its place by rotating a screw B³
which engage with it and has a bearing in the rear wall of the header. A jam-
nut, E, is shown as applied to its outer end. This elliptical hand-hole extends
opposite to two tubes A.
In Figure 25, I have shown a group of headers, severally having two tubes A
connected thereto. Opposite the openings which receive these tubes there is in the

page_text: front wall of each header an elliptical hand-hole 64. The cap or cover for such hand-
bole is like the cap or cover for the elliptical hand-hole shown in Figures 23 and 24,
and is forced and held in place in like manner.
In Figure 26 I have shown headers approximately rhomboidal in shape. Each has
four tubes A connected to it. There is a rhomboidal hand-hole, 64, in the front wall
of each header, and this hole has a similarly shaped cap or cover combined with it.
The cap or cover may be forced to its place and held there by a screw operating in
any of the ways illustrated by Figures 18, 20, 21, 22, 32, and 33. Similarly-shaped
headers are shown in Figure 27, but here differently-shaped hand-holes are provided.
Small circular hand-holes 68, like the circular hand-holes shown in Figures 23
and 24, are provided. They may have combined with them similarly-shaped caps or
covers. An elliptical hand-hole, 67, is also provided in each of these headers. The
small circular caps or covers may be inserted through the elliptical hand-hole and
"secured in place by screws used like those which are shown in Figs. 23 and 24 as
combined with the caps for the circular hand-holes there illustrated. The caps or
covers for the elliptical hand-holes b7 in Figure 27 may be secured in place in the
same manner as the caps or covers for the elliptical hand-holes in Figures 23 and 24
are shown as secured in place. I desire to cover, broadly, the idea of using one or
more large hand holes and a number of small hand-holes in a single header in
substantially the manner described.
In Figure 28 I have shown similarly-shaped headers severally having two elliptical
hand-holes extending each opposite two tubes A.
With these elliptical hand-holes caps or covers of like shape are combined. They
may be forced into place and held there in any of the ways in which the caps or
covers illustrated in Figs. 18, 20, 21, 22, 32 and 33 are secured in place.
In Figure 29 I have shown a rectangular header having four tubes or pipes A
secured to it. It has two elliptical openings in the front, and to these are fitted
two similarly-shaped caps or covers B₁ which are secured in place in the same way as
the others, as shown in Figures 18, 20, 21, 22, 32 and 33.
In Figures 30, 31, 32, 33 and 34 I have shown a rectangular header having one or
more tubes A secured to it, and provided with a single opening opposite each tube.
The screw B, employed to secure the cap or cover in place, is supported at one end
in a tripod in the example of my improvement shown in Figures 30 and 31. In the
example of my improvement shown in Figure 30, the tripod bears against the back
of the header and is centered by bearing against the end of the tube A, as shown
in Figure 24. The screw 132 is combined with the cap or cover B', as illustrated
in Figures 17 and 24. In the example of my improvement shown in Figure 31, the
screw is rigidly connected to the tripod, and combined with a nut, G2, like the screw
and cover shown in Figure 21. A jam-nut E, is shown as combined with the nut, G².
The screw is not intended to rotate in the example of the improvement shown
in Figure 31. The bridge-piece in this example of my improvement, bears against
the end of the tube or pipe A, and is centered by the latter.
The headers shown in Figures 30 and 31 severally have an elliptical opening *, and
a similarly-shaped cap or cover.
The headers shown in Figures 32, 33 and 34, severally, have a bar-shaped bridge-
piece P, inserted in sockets or cavities c', in the top and bottom or sides of the header.
In front of these headers and opposite the end of each tube, is an elliptical hand-hole,
with which is combined a cap or cover of the same shape. The cap or cover shown
in Figure 32, is secured in place by a screw, B2, which rotates loosely in the cap or
cover, engaged with a tapped hole in the bridge-piece. The cap or cover shown in
Figure 33, is secured in place by a screw B³, which has a bearing in the bridge-piece,
but does not screw into it. This screw engages with a tapped hole in the cap or cover.
Outside the cap or cover, a jam-nut engages with the screw and clamps it against the
cover.
Figure 35 illustrates two long horizontal headers, having elliptical hand-holes * in
the front, and elliptical caps or covers, which may be secured in piace according to any
of the ways illustrated in Figures 18, 20, 21, 22, 24, 30, 31, 32 or 33.

page_text: Figure 36 shows a sinuous header which may be composed of any number of
sections connected by nipples D), or may be made in one piece or casting. In the
front are elliptical hand-holes, having similarly-shaped caps or covers, which may
be secured in place by any of the ways shown in Figures 18, 20, 21, 22, 24, 30, 31,
32 or 33.

[Communicated from abroad by WILLIAM EDWARD KELLY, of No. 65, George Street,
New Brunswick, New Jersey, United States of America, Manufacturer.]
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention to be as follows:-
My invention relates to a steam generator in which a number of tubes are arranged
upon an incline and subjected to the heat from a furnace. Water circulates through
these tubes, which are connected at their ends to headers, and the headers are united
one above another and connected with a steam and water drum into which the water,
when sufficiently heated, and steam will ascend. The cooler water will descend from
the drum to the lower end of the inclined tubes, whereby a continuous circulation is
kept up. Each of the headers may have one or more of the circulating tubes connected
to it.
The said invention consists first in a combined header and saddle placed under the
forward end of the steam and water drum and affording communication between the
inclined tubes and the drum. This saddle is cast hollow, and provided with a conduit
which is closed against the admission of steam or water from the saddle. This conduit
may be cast in the saddle.
A pipe secured in a suitable opening in the conduit affords communication between
the latter and the interior of the drum. Another pipe secured in another opening in
the conduct extends outwardly and connects near its outer end with a water gauge
column. The upper end of the water gauge column communicates by means of a
pipe with a conduit in a nozzle or nipple for a safety valve, or other suitable outlet

page_text: nozzle, which conduit is likewise closed to the interior of the nozzle. From this
conduit extends another pipe into the steam space of the drum.
The said invention further consists in another conduit in the saddle similar to the
one previously referred to, with which communicate feed water pipes by which water
is supplied to the interior of the drum.
The invention also partly consists in providing the nozzle or nipple for the safety
valve, or other outlet nozzle, with a conduit closed to the interior of the nozzle
from which extends a pipe to the interior of the drum, and another pipe to a steam
gange.
The invention also partly consists in a saddle similar to the one referred to but
located at the rear of the drum. This saddle affords communication with the inclined
tubes for the return water, and is provided with two conduits similar to those described
in the other saddle with which connect pipes from a scum-collector and blow-off pan
within the drum, and also other pipes leading to the outside of the generator through
which scum may be blown off.
An important feature of my invention consists in the flame plates by which the
products of combustion are caused to follow a circuitous course through the inclined
circulating tubes. These flame plates are made up of sections. Each of these sections
is undivided and has one or more of the circulating tubes extending through it, and
when the sections are in place, they form a continuous flame plate, the sections being
superposed one upon the other. Each of the sections is the same shape as the headers
to which the circulating pipe or pipes which extend through such section are secured.
The sections are made of iron and are hollow. They will preferably be cast in such
manner that they will have a back, a rim extending about the edges, and thimbles
formed in suitable positions in the back and extending forward approximately coincident
with the rim. Pins or projections extend from the back toward the front of the
sections. These pins are preferably arranged at inclines to each other, and may be
cast with the sections or secured therein in any suitable manner.
The spaces within
the hollow sections are filled with fire clay or other material. The pins serve to retain
the fire clay in position when such is used. The sections of the flame plates may be
secured together at their backs by means of pins or bolts passing through lugs on the
sections.
Another feature of my invention consists in the form of the channel irons above
the drum and the arrangement of the hooks by which the drum is supported from the
channel irons. The channel irons have flanges upon their lower sides which extend
inwardly or toward each other, whereby a considerable space is left between the
channel irons. I employ but a single hook with each pair of channel irons, which
hook is accommodated within the space between the channel irons. The hooks engage
with iron loops rivetted to the drum.
Still another feature of my invention consists in the headers, to which the inclined
tubes are connected. For closing such headers I employ a cup or cover having a
bearing against the inner surface or side of the header, in which is arranged the
opening to be closed. The means for securing the cap or cover in place forces the
latter outwardly, while its thrust is sustained in rear of the cap or cover. Steam
pressure forcing or tending to force the cap or cover outwardly, acts to tighten, rather
than loosen, the joint. In one example of this part of my invention each of the
headers is approximately triangular but has the lower portion of the sides chamfered
off vertically, the upper portions of the sides extending vertically and a flat top.
Any desired number of these headers may be suitably arranged and connected
together by intermediate nipples, secured in openings of the headers, water will flow
from one header to another through the connecting nipple. Each of the headers in
this example of my invention has three holes or openings for the reception of circulating
tubes. Each of them also has in the front a hand hole or opening of approximately
triangular shape but the corners will preferably be rounded. This opening is closed
by a cap or cover, which is the same shape as the opening only slightly larger and
will preferably be provided with a rib upon one side extending about it inwards from

page_text: the edge. This cap or cover is inserted edgewise through the opening, and then
adjusted into place by the aid of handles with which it is provided, so that its rib will
fit the edge of the opening, and its portion which extends beyond the rib will fit
against the back of that wall or side of the header in which the front opening is
arranged. The cap is secured in place by means of a screw.
In this example of my
invention the screw has an end bearing in the back of the header and can rotate in
this bearing. It passes through the cap or cover and engages with a screw thread
formed in the same. By engaging the cap or cover with the screw fitting the latter
in its bearing and rotating it, the cap or cover may be forced outwardly to its place.
A jam nut may be applied to the screw outside the cap or cover.

page_text: Improvements in Steam-boilers or Generators.
I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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:-
My invention relates to a steam generator in which are a number of tubes arranged
upon an incline and subjected to the heat from a furnace. Water circulates through
these tubes, which are connected at their ends to headers and the headers are united
one above the other and connected with a steam and water drum into which the
water, when sufficiently heated, and steam will ascend. The cooler water will descend
from the drum to the lower end of the inclined tubes whereby a continuous circulation
is kept up.
Each of the headers may have one or more of the circulating tubes
connected to it.
The invention consists first in a combined header and saddle placed under the
forward end of the steam and water drum and affording communication between the
inclined tubes and the drum. This saddle is cast hollow, and is provided with a
conduit which is closed against the admission of steam or water from the saddle.
This conduit may be cast in the saddle. A pipe secured in a suitable opening in the
conduit affords communication between the latter and the interior of the drum.
Another pipe secured in another opening in the conduit extends outwardly and
connects near its outer end with a water gauge column. The upper end of the water
gauge column communicates by means of a pipe with a conduit in a nozzle or nipple
for a safety valve, or other suitable outlet nozzle, which conduit is likewise closed to
the interior of the nozzle. From this conduit extends another pipe into the steam
space of the drum.
The invention, further consists in another conduit in the saddle, similar to the one
previously referred to, with which communicate feed water pipes by which water is
supplied to the interior of the drum.
The invention also consists in providing the nozzle or nipple for the safety
valve, or other outlet nozzle, with a conduit closed to the interior of the nozzle, from
which extends a pipe to the interior of the drum and another pipe to a steam guage.
The invention also consists in a saddle similar to the one referred to but located at
the rear of the drum. This saddle affords communication with the inclined tubes for
the return water and is provided with two conduits similar to those described in the
other saddle, with which connect pipes from a scum collector and blow-off pan within
the drum, and also other pipes leading to the outside of the generator through which
scum may be blown off.
An important feature of my invention consists in the flame plates by which the
products of combustion are caused to follow a circuitous course through the inclined
circulating tubes. These flame plates are made up of sections. Each of these sections
is undivided and has one or more of the circulating tubes extending through it, and
when the sections are in place they form a continuous flame plate, the sections being

page_text: superposed, one upon the other. Each of the sections is the same shape as the headers
to which the circulating pipe or pipes which extend through such section, are secured.
The sections are made of iron and are hollow. They will preferably be cast in such
manner that they will have a back, a rim extending about the edges and thimbles
formed in suitable positions in the back and extending forward approximately
coincident with the rim. Pins or projections extend from the back toward the front
of the sections. These pins are preferably arranged at inclines to each other, and may
be cast with the sections or secured therein in any suitable manner.
The spaces
within the hollow sections are filled with fire clay or other material. The pins serve
to retain the fire clay in position when such is used. The sections of the flame plates
may be secured together at their backs by means of pins or bolts passing through lugs
on the sections.
Another feature of my invention consists in the form of the channel irons above
the drum and the arrangement of the hooks by which the drum is supported from the
channel irons. The channel irons have flangos upon their lower sides, which extend
inwardly or toward each other, whereby a considerable space is left between the
channel irons. I employ but a single hook with each pair of channel irons, which
hook is accommodated within the space between the channel irons. The hooks
engage with iron loops riveted to the drum.
Still another feature of my invention consists in the headers to which the inclined
tubes are connected. For closing such headers I employ a cap or cover having a
bearing against the inner surface or side of the header in which is arranged the
opening to be closed. The means for securing the cap or cover in place, forces the
latter outwardly while its thrust is sustained in rear of the cap or cover. Steam
pressure forcing or tending to force the cap or cover outwardly acts to tighten rather
than, loosen the joint. In one example of this part of my invention, each of the
headers is approximately triangular, but has the lower portion of the sides chamfered
off vertically; the upper portions of the sides extending vertically and a flat top.
Any desired number of these headers may be suitably arranged and connected
together by intermediate nipples secured in openings of the headers. Water will
flow from one header to another through the connecting nipple. Each of the headers
in this example of my invention has three holes or openings for the reception of
circulating tubes. Each of them also has in the front a hand hole or opening of
approximately triangular shape, but the corners will preferably be rounded. This
opening is closed by a cap or cover which is the saine shape as the opening only
slightly larger, and will preferably be provided with a rib upon one side extending
about it inwards from the edge. This cap or cover is inserted edgewise through the
opening and then adjusted into place by the aid of handles with which it is provided
so that its rib will fit the edge of the opening and its portion which extends beyond
the rib will fit against the back of that wall or side of the header in which the front
opening is arranged. The cap is secured in place by means of a screw. In this
example of my invention the screw has an end bearing in the back of the header.
It can rotate in this bearing. It passes through the cap or cover and engages with a
screw thread formed in the same. By engaging the cap or cover with the screw,
fitting the latter in its bearing and rotating it, the cap or cover may be forced out-
wardly to its place. A jam nut may be applied to the screw outside the cap
or cover.

tubes which are connected to the headers and embodying my improvement. Figure 36
is a front view of a sinuous header embodying my improvement.
Similar letters of reference designate corresponding parts in all the figures.
I will first describe generally the steam generator which I have shown in Figure 1,
to illustrate the various features of my improvement, premising, however, that said
improvements are not confined in their application to steam generators of this style.
A designates a number of tubes which are arranged upon an incline and subjected
to the influence of the heat of the products of combustion from a furnace. These
tubes are connected at their ends to headers B, and the headers B are united one
above another, and connected with a steam and water drum, C, so that water, when
sufficiently heated, and steam may ascend through the inclined tubes, and rise through 5
headers B, to which the upper ends of the inclined tubes are connected, into the
drum C, and so that the cooler water will descend from the drum C, into and through
the headers to which the lower ends of the inclined tubes are connected, and pass
from these headers into the inclined tubes.
D designates a combined header and saddle placed under the forward end of the 5
steam and water drum C, and affording a means of communication between the
inclined tubes and the drum. This saddle will be cast hollow, and preferably provided,

page_text: for the purpose of increasing its strength, with vertical partitions a, dividing it into
compartments, communication between the compartments being afforded by means of
openings in the partitions. The upper row of headers B communicates with the
saddle D by means of nipples e expanded or screwed into openings d in the lower side
of the saddle D and into corresponding openings in the upper sides of the headers.
The saddle is provided with a curved flanged portion d', upon which the drum
rests, and which is riveted to the drum. An opening in the drum affords com-
munication between the drum and the saddles. The saddle is provided with a
conduit D' which is closed against the admission of steam or water from the saddle.
This conduit may be cast in the saddle. A pipe D' secured near one end in a suitable
opening in the conduit D¹, affords communication between the conduit and the interior
of the drum. A pipe D³ secured at one end in a suitable opening in the conduit D'
below the drum extends outwardly, and connects near its outer end to the lower end
of a water gage column D. The upper end of the water gage column D communicates
with a nozzle or nipple, D³, for a safety valve De, by means of a pipe D'. Within
the nozzle D³ is formed a conduit e (shown more clearly in Figures 11, 12, 13, 14, 15
and 16) with which the pipe D' communicates and with which there is also connected
a pipe D extending into the steam space of the drum. Water is supplied to the water
grage column from the pipe D², which latter, it will be observed, extends well away
from the point where the saddle communicates with the drum, and hence to a point
where the water is less agitated than near the opening.
D designates a conduit similar to the conduit D, and likewise arranged in the
saddle D. Feed-water pipes D10 D1 communicate with this conduit, whereby water
may be fed to the drum. It is an important feature of this arrangement that I am
not obliged to cut holes in the shell of the drum C in order to introduce any of the
pipes for the water-gage or the feed-water pipe. The cutting of such holes is very
difficult of execution and can seldom be done with a desired degree of accuracy, and
also has a tendency to weaken the shell of the drum. By providing the saddle D and
nozzle D³, therefore, with closed conduits, with which the pipes of the water gage and
feed-water pipe communicate, inuch time and labor are saved because the conduits
may be cast in the saddle and nozzle and the holes for the reception of the pipes
may be tapped before the saddle and nozzle are secured to the drum.
do not wish to be understood as limiting myself to the precise shape of the
conduits D and e, nor to the particular manner of connecting the several pipes
thereto, as these may of course be varied. Figures 14, 15 and 16 illustrate different
methods of forming the conduits e in the nozzle D, and like modifications of form
or even different ones may be employed in the saddle.
In Figures 1, 11 and 12 I have shown a means of affording communication between
the interior of the drum and a steam pressure gage, E, without cutting a hole
through the shell of the drum, consisting in a pipe E', communicating at one end
with the steam-gage, and at the other with a conduit e' in the nozzle D³, similar to
the conduit e. A pipe e extends from the conduit el into the interior of the drum.
F designates a saddle somewhat similar to the saddle D, located beneath and near the
rear end of the drum and riveted to the drum. This saddle affords communication
with the circulating tubes A for the returning water, tubes f being connected to it
and the headers B at the lower end of the inclined tubes A. This saddle is provided,
as shown, with two conduits ", similar to the conduits D, with which pipes from
a scum-collector and blow-off pan f³, communicate. Pipes falso connect with the
conduits and extend outside the generator, through which scum may be blown off.
Of course, feed-water pipes can be introduced into the saddle F, if desirable. By
riveting the saddles D and F to the drum the latter is braced and strengthened.
Another important feature of my improvement consists in the flame plates K K',
by which the flame and products of combustion are caused to follow a circuitous
course through the circulating tubes. These flame plates are made up of sections G,
which will preferably conform to the form of the headers B each of which headers is
shown in this example of my improvement as receiving three of the circulating tubes.
I have shown this arrangement more clearly in Figure 8; but I do not wish to be

page_text: I,
understood but that other forms of headers and flame-plates may be used than those
shown. The sections G of the flame-plates are made of iron and are hollow. They
will preferably be cast in such manner that they will each have a back
a rim g,
extending about the edges and thimbles gå formed in suitable positions in the back
and extending forward approximately coincident with the rim g'. Pins or pro-
jections g³ extend from the back toward the front of the sections. As shown they are
arranged at inclines to each other. They may be cast with the sections or secured
therein in any suitable manner. It is intended that the space within the sections
shall be filled with fire-clay or similar material s. Where such material is used the
pins g³ serve to retain it in position. I may however, fill in the spaces with bricks
of suitable form which may be driven in or secured therein in any suitable manner.
In such case the pins might be omitted. So far as the pins g₁ and their arrangement
are concerned, the flame-plates might of course be of any desired form. The sections
are provided upon their rear sides with lugs go, through which pins or bolts gⓇ may be
passed to secure them together when in position about the pipes. The circulating-
tubes extend through the thimbles g², which latter protect the clay within the sections
from the rubbing of the tubes. It will be advantageous to place the flame-plate
sections in position on the tubes as shown in Figure 8, before shipment, and fill them
with the clay or other material when the generator is being erected. The heat of
the furnace may then be depended on to bake the clay hard. The sections are
superposed one upon the other, and do not overlap.
f
In Figure 10, I have shown a flame-plate section of modified form, composed of a
number of parts, s¹, secured together and held in place by bolts. Although this
flame-plate is made up of a number of parts, it is undivided, said parts being con-
nected rigidly together, so as not to be capable of separating or dividing when in use.
Flame plates made according to my improvement are cheap, desirable, will not warp,
and are easily placed in position.
Another feature of my improvement consists in the channel-irons J above the
drum, and the mode of arranging the hooks by which the drum is supported from
the channel-irons. The channel-irons, it will be observed, have flanges upon their
lower sides, which extend inwardly or toward each other, whereby a considerable
space is left between the channel-irons. By thus forming the channel-irons I am
enabled to use but a single hook, J', with each set of channel-irons, which hook is
enclosed within the space between the channel-irons, thereby enabling the channel-
irons to be brought much closer to the drum, than has heretofore been possible when
⚫ single hooks have been used. The hooks J engage with iron loops J', riveted to the
drum. The height of the generator is therefore materially reduced, which is a
desirable feature.
Instead of the conduits e e¹ being arranged in a safety-valve, they may be arranged
in any other suitable outlet-nozzle.
I will now particularly describe the various examples of headers with the appur-
tenances thereof which I have shown.
Referring first to Figures 17 and 18, B designates headers, each of which is
approximately triangular, but has the lower portions of the sides chamfered off
vertically, the upper portions of the sides extended vertically, and a flat top. I have
in this figure shown four of these headers connected together one above the other by
intermediate nipples c, which will preferably be secured in the openings d³ of the
headers in which they fit by expanding them into such openings, Water will flow
from one header to another arranged above or below it through the connecting
nipple. Any desirable number of the headers may of course be similarly arranged and
connected.
In Figure 19, I have shown that headers, such as I have illustrated in Figures 17
and 18, arranged one above another, may be cast integral, so as to form one structure.
Any desirable number of headers may be cast together in this manner.
Each of the headers shown in Figures 7 and 19 has three holes or openings, 61 62 6³,
for the reception of tubes A such as 1 have illustrated in Fig. 1. Each of these
headers has in front a hand-hole or opening, 4, of approximately triangular shape;

page_text: but the corners will preferably be rounded. This opening 6 is closed by a cap or
cover, B', which is of the same shape as the opening 6 only slightly larger and is
preferably provided with a rih 6. This cap or cover is inserted edgewise through
the opening 64, and then adjusted into place by the aid of handles 6, with which it is
furnished, so that its rib b will fit the edge of the opening, and its portion which
extends beyond the rib will fit against the back of that wall or side of the header in
which the opening 6 is arranged. A packing of soft suitable material may be inter-
posed between the edge portion of the cap and the rear surface of the front of the
header.
The cap or cover B₁ is secured in place by means of a screw B', whereby it is forced
outward. In Figure 18, this screw is shown as having an end bearing in the back of
the header. It can rotate in this bearing. It passes through the cap or cover B¹,
and engages with a screw thread which is forined in the cap or cover. By engaging
the cap or cover with the screw, fitting the latter in its bearing and rotating it, the
cap or cover may be forced outwardly to its place. A jam-nut E', may be applied to
the screw outside the cap or cover.
I have shown in Figure 20 that, instead of forming a screw-thread in the cap or
cover, I may fit in the cap or cover an internally screw-threaded bushing S, for
engaging with the screw. The bushing must be shaped externally so that it will not
turn in the cap or cover. It will be observed that the rear portion of the screw is
smaller in diameter than the forward part, where the screw-thread is located. This
reduces the liability of incrustations on the screw interfering with the adjustment of
the cap or cover. It also expedites the moving of the cap or cover to its place,
because the cap or cover, when the screw is thus made, does not need to be adjusted
along an unnecessary length of screw-thread.
In Figure 21, the screw B' has a right-hand screw-thread at one end and a left-
hand thread at the other. One end is inserted in a tapped hole in the back of the
header and the other end engages with a nut G, which is fitted into the cap or
cover B¹. This nut has a polygonal boss, to which a wrench may be fitted for the
Thus the cap
purpose of rotating it within the cap or cover, and around the screw.
or cover will be forced outwardly. A packing may be used around the nut, if
desirable. Of course I may use a second nut upon the nut G, to clamp against the
outer side of the cap or cover.
Figure 22 illustrates that a screw B³ may be made to turn loosely in the cap or
cover without engaging therewith, and to screw into a tapped socket, o, in the rear
wall of the header. This socket, o, will preferably be extended rearward, so as not
to interfere with a free flow of water through the header. A jam-nut, E', may be
applied to the outer end of the screw and bear against the outer surface of the cap or
cover.
Figures 23 and 24 show that a header such as I have described may have one
elliptical hand-hole 67, and one circular hand-hole 68, instead of a single large
triangular band-hole. The two hand-holes will have caps or covers B¹ of correspond-
ing shapes combined with them. The cap or cover for the small hand-hole will be
inserted through the large hand-hole. It will then be engaged with the screw B'
whereby it is to be secured in place. The screw B' in this case, has a bearing in a
tripod B, which bears against the rear wall of the header, and is centered by one of
the tubes A. The tripod may indeed be made resilient and then can be made to hug
the end of the tube so as to remain in place. It is not intended to rotate. The
screw B will be rotated after engagement with the tripod to force the cap or cover
with which it engages outwardly to its place. A jam-nut, E, may be combined with
the outer end of the screw. The cap or cover for the large elliptical hand-hole will
be afterward inserted in the header and forced to its place by rotating a screw B³
which engages with it and has a bearing in the rear wall of the header. A jam-
nut, E, is shown as applied to its outer end. This elliptical hand-hole extends
opposite to two tubes A.
In Figure 25, I have shown a group of headers, severally having two tubes A
connected thereto. Opposite the openings which receive these tubes there is in the
B

page_text: front wall of each header an elliptical hand-hole 64. The cap or cover for such hand-
hole is like the cap or cover for the elliptical hand-hole shown in Figures 23 and 24,
and is forced and held in place in like manner.
In Figure 26 I have shown headers approximately rhomboidal in shape. Each has
four tubes A connected to it. There is a rhomboidal hand-hole, 64, in the front wall
of each header, and this hole has a similarly shaped cap or cover combined with it.
The cap or cover may be forced to its place and held there by a screw operating in
any of the ways illustrated by Figures 18, 20, 21, 22, 32, and 33. Similarly-shaped
headers are shown in Figure 27, but here differently-shaped hand-holes are provided.
Small circular hand-holes 68, like the circular hand-holes 68 shown in Figures 23
and 24, are provided. They may have combined with them similarly-shaped caps_or
covers. An elliptical hand-hole, b', is also provided in each of these headers. The
small circular caps or covers may be inserted through the elliptical hand-hole and
secured in place by screws used like those which are shown in Figs. 23 and 24 as
combined with the caps for the circular hand-holes there illustrated. The caps or
covers for the elliptical hand-holes 67 in Figure 27 may be secured in place in the
same manner as the caps or covers for the elliptical hand-holes in Figures 23 and 24
are shown as secured in place. I desire to cover, broadly, the idea of using one or
more large hand holes and a number of small hand-holes in a single header in
substantially the manner described.
In Figure 28 I have shown similarly-shaped headers severally having two elliptical
hand-holes extending each opposite two tubes A.
With these elliptical hand-holes caps or covers of like shape are combined. They
may be forced into place and held there in any of the ways in which the caps or
⚫covers illustrated in Figs. 18, 20, 21, 22, 32 and 33 are secured in place.
In Figure 29 I have shown a rectangular header having four tubes or pipes A
secured to it. It has two elliptical openings 6 in the front, and to these are fitted
two similarly-shaped caps or covers B which are secured in place in the same way as
the others, as shown in Figures 18, 20, 21, 22, 32 and 33.
In Figures 30, 31, 32, 33 and 34 I have shown a rectangular header having one or
more tubes A secured to it, and provided with a single opening opposite each tube.
The screw B, employed to secure the cap or cover in place, is supported at one end
in a tripod in the example of my improvement shown in Figures 30 and 31. In the
example of my improvement shown in Figure 30, the tripod bears against the back
of the header and is centered by bearing against the end of the tube A, as shown
in Figure 24. The screw B' is combined with the cap or cover B¹, as illustrated
in Figures 17 and 24. In the example of my improvement shown in Figure 31, the
screw is rigidly connected to the tripod, and combined with a nut, G³, like the screw
and cover shown in Figure 21. A jam-nut E, is shown as combined with the nut G².
The screw is not intended to rotate in the example of the improvement shown
in Figure 31. The bridge-piece in this example of my improvement, bears against
the end of the tube or pipe A, and is centered by the latter.
The headers shown in Figures 30 and 31 severally have an elliptical opening 6', and
a similarly-shaped cap or cover.
The headers shown in Figures 32, 33 and 34, severally, have a bar-shaped bridge-
piece P, inserted in sockets or cavities c¹, in the top and bottom or sides of the header.
In front of these headers and opposite the end of each tube, is an elliptical hand-hole,
with which is combined a cap or cover of the same shape. The cap or cover shown
in Figure 32, is secured in place by a screw, B', which rotates loosely in the cap or
cover, engaged with a tapped hole in the bridge-piece. The cap or cover shown in
Figure 33, is secured in place by a screw B³, which has a bearing in the bridge-piece,
but does not screw into it. This screw engages with a tapped hole in the cap or cover.
Outside the cap or cover, a jam-nut engages with the screw and clamps it against the
cover.
Figure 35 illustrates two long horizontal headers, having elliptical hand-holes 6* in
the front, and elliptical caps or covers, which may be secured in place according to any
of the ways illustrated in Figures 18, 20, 21, 22, 24. 30. 31. 32 or 38.

page_text: Figure 36 shows a sinuons header which may be composed of any number of
sections connected by nipples D, or may be made in one piece or casting. In the
front are elliptical hand-holes 6', having similarly-shaped caps or covers, which may
be secured in place by any of the ways shown in Figures 18, 20, 21, 22, 24, 30, 31
32 or 33.
