THE MANUFACTURE OF PIPES, TILES, BRICKS, STAIRS, COPINGS, AND OTHER LIKE OR
SIMILAR ARTICLES, FROM PLASTIC MATERIALS; ALSO IMPROVEMENTS IN MACHINERY TO
BE EMPLOYED THEREIN;" in which said Letters Patent there is contained a
proviso requiring that I, the said Bennett Alfred Burton, should particularly
describe and ascertain the nature of my said Invention, and in what manner
the same is to be performed, by an instrument in writing under my hand and

page_text: seal, and cause the same to be enrolled in Her said Majesty's High Court of
Chancery within six calendar months next and immediately after the date of
the said in part recited Letters Patent, as, reference being thereunto had, will
more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Bennett Alfred Burton, do hereby declare the nature of my Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained in and by the following statement thereof, that is to say :-
My Improvements in the manufacture of pipes, tiles, bricks, copings, and
other like or similar articles composed of plastic materials, consist,
Firstly, of compressing the particles of matter of which such articles are
composed so as to bring such particles into closer contact, whereby such articles
are rendered more solid and durable, and therefore capable of withstanding a
greater pressure. The manner in which I propose to effect this object will be
understood by the following description, reference being had to the Sheet of
Drawings marked A, in which similar letters denote corresponding parts in all
the Figures.
DESCRIPTION OF DRAWING.
Figure 1, Sheet A, represents a side elevation; Figure 2 a front or vertical
sectional elevation; and Figure 3 a plan of a machine for making, and after-
wards compressing, pipes composed of earthenware or other plastic materials.
a, a, are the two side frames of the machine; b, the main or driving shaft; and
c, c, a loose and fast pulley for giving motion to the same by means of a strap.
Upon the shaft 6 there are two bevil wheels working loosely, and between
them there is a sliding clutch box, e, with a fixed key made to fit into a slot cut
upon the shaft b, so that by moving the sliding clutch box upon the shaft,
which is effected by means of a lever, f, (see Figure 3,) motion will be given
by the main shaft to the wheel d, or d', as the case may be. g is a bevil wheel
which takes into and is driven alternately by the wheels d and d'. This wheel,
9, which is keyed upon the end of a vertical shaft, h, gives motion by means
of that shaft and a pinion, i, to a wheel, k, supported by a cross bar or stay,
7 (see Figures 2 and 3). m is a nut made to fit loosely in a hole bored through
the centre of the cross bar, and upon the upper end of this nut is firmly keyed
the wheel k, so that by giving motion to the wheel k, the screw n, which
passes through the nut will be raised or lowered, as the case may be, depending
upon the direction of motion of the wheel k, which can be changed at
pleasure by sliding the clutch box e, into gear with the wheel d or d', as will
be understood. 0, 0, represents the lower portion of the clay cylinder; p, the
die plate; and 9 the die; q', q', being a long hollow mandril (or the same may

page_text: be solid) attached to and forming a portion of the die which is bolted to the
die plate inside the cylinder. The die plate and cylinder o are supported by
brackets and cross beams bolted to the side framing (see x, Figures 1 and 2).
The cylinder o is cast with a large flange o¹, forming a circular projecting table,
see Figure 4, which represents a plan and edge view. The clay cylinders, r, r, are
cast together upon a sole plate r', r¹, the whole being supported by the circular
table o', a hole being bored in the centre of the table which receives a stud
cast upon the underside of the sole plate of the clay cylinders, the underside
of the sole plate and top side of the table being turned and faced so that they
may fit close together. The object of this arrangement is to allow of the
cylinder being brought alternately under the screw n, so that one cylinder may
be filled with clay during the operation of making pipes from the clay contained
in the other cylinder. On the top side of the sole plate r' there is cast two
inclined planes, ", which, as the cylinders are moved round (so as to be
brought under the screw), come in contact with a double inclined plane, o", cast
upon and projecting from the edge of the circular table o', so that when either
of the clay cylinders is brought underneath the screw, for the purpose of forcing
the clay through the die, the cylinder or cylinders may be held firmly in their
place; or the sole plate of the cylinders may, if preferred, be bolted to the
table. The cylinders are moved upon the table by a crow bar or lever, which
may be inserted into a hole y, cast in the edge of the plate r', see Figs. 1
and 4. Figure 5 represents a plan of that portion of the machine for com-
pressing the particles of matter of which the pipes are composed after they have
been formed by forcing the plastic material through the dic. This portion of
the machine consists of four rollers of cast iron or other suitable material,
1, 2, 3, 4, their peripheries being turned to such a shape that when placed
together, as shewn, they may form a circular hole, somewhat smaller in diameter
than the external diameter of the pipes to be compressed. Each of the rollers
1, 2, 3, 4, is supported by suitable bearings bolted to the cast iron frames, s,
the frame s, s, and rollers, being supported by brackets bolted to the side frame
a, a, of the machine. v, v, are set screws for holding and adjusting the frame
s, 8, so that the centre of the hole formed by the peripheries of the four rollers
may be set concentrically with the end of the mandril q'. Motion is communi-
cated to the rollers as follows:-Upon the end of the driving shaft there is keyed
a pinion, t, which takes into and drives a wheel, u, keyed upon the shaft of the
roller 1, and upon the shaft or axis of the roller 1 there is keyed a bevil wheel
which drives a bevil wheel upon the axis of the roller 2, and upon the axis of
the roller 2 there is a bevil wheel which drives the roller 3, and upon the axis of
the roller 3 there is another bevil wheel which drives a wheel keyed on the axis

page_text: of the roller 4, so that the four rollers are driven in the same direction and
with the same surface velocity. The action of the machine is as follows:-
One of the cylinders having been filled with clay is moved round upon the
table so as to be brought underneath the screw, where it is held fast by the
inclined planes before described. Motion being given to the machine, the screw,
which is provided with a piston at its lower end, forces the clay through the die
and over the mandril q', the lower end of which just comes below the centre
line of the rollers. A portion of the clay having been forced through the die,
equal to the length of pipe required, such portion is cut off by means of a wire
or other suitable instrument. For this purpose it will be seen that a small
groove is cut in the mandril close to the die, for the purpose of receiving the
wire. The length of pipe required having been cut off, drops down, and is
carried through or between the rollers and over the end of the mandril, whereby
the material forming the pipe becomes compressed, the particles brought into
closer contact, thereby producing a pipe more perfect and regular in its
structure, and when baked in the ordinary manner capable of withstanding
a greater pressure.
The machine, as just described, is intended more particularly for large pipes,
although the same may be employed for small pipes. But when small pipes
are required I propose to make them in a separate machine having five or
six dies, through which clay for as many pipes may be forced at one and the
same time.
The object of employing a machine for making the pipes distinct
from the compressing machine is simply because the latter will compress the
pipes much faster than they could be made in a machine having but one die.
I therefore propose to make the pipes in a separate machine, and afterwards
consolidate them in a machine similar to one represented on Sheet B, and of
which the following is a description:-
Figure 1 represents a side elevation, and Figure 2 a front view, partly in
section. a, a, are the side frames; b, the driving shaft; c, c, loose and fast
pulleys; t, a pinion, keyed upon the end of the driving shaft, which gives
motion to the compressing rollers by means of a wheel, u; the arrangement
of the rollers and mode of driving being the same as the machine just de-
scribed, the principal difference in the two machines being that the clay
cylinders are removed, and a provision made for raising and lowering the man-
dril, so that the pipes may be placed upon it for the purpose of being com-
pressed, which will be understood by the following description, reference being
had to Sheet B. A, A, Figures 2 and 3, is a cross head supported by two
square bars, B, B, the latter being supported by brackets, C, C, bolted to the
side frames of the machine. The bars B, B, therefore, form guides for the

page_text: This part of the machine is actuated
cross head to slide upon, and the mandril q', which is bolted to the under side
of the cross head, is capable of being raised or lowered in the following
manner :-D is a shaft, supported in bearings bolted to the top of the frame
sides; at or near the middle of this shaft there is a pinion, E, the teeth of which
enter a rack, F, the lower end of the rack being bolted to the cross head A.
G is a strap passing over a flanged pulley keyed upon the end of the shaft D,
and under a pulley keyed upon the driving shaft b. This strap, which is
technically termed a loose strap, is intended to communicate motion from the
shaft b to the shaft D, for the purpose of raising the cross head and mandril,
by giving motion to the pinion and rack.
by means of a tightening pulley, H, supported by a lever keyed upon a stud, I,
moving freely in a bearing bolted to the side frame a. Upon the stud I there
is also fixed a lever, K, and to the end of that lever there is attached by pin joint
a rod, L, the lower end of which is attached in a similar manner to a lever keyed
upon the end of a shaft, M, and upon this shaft there is a pedal, N. It will,
therefore, be seen that when the attendant presses with his foot upon the pedal N
that the tightening pulley will be pressed against the strap, and motion will be
given to the shaft D, and the cross head and mandril will be raised. Upon the
stud I there is also a bent lever, O, shewn in dotted lines (see Figure 1).
The object of this lever is to prevent any accident occurring by the cross head
running up too far. This is effected by bolting an inclined plane, P, to the top
of the cross head, so that when the cross head has arrived at its proper height
the inclined plane P, coming in contact with the bent lever O, forces that lever
back, and pulls away the tightening pulley so as to slacken the strap, at the
same time warning the attendant by the pressure of the pedal against his foot
that the mandril has arrived at its proper height. This being the case, it will
be necessary to retain it in that position while the attendant places a pipe
under the mandril, for the purpose of being compressed by passing through the
rollers. This is effected by means of a catch, Q, (see Figure 1,) keyed upon
the end of a stud, moving freely in a socket or hole formed in the frame side.
To the outer end of this stud is fixed a lever, R, to the end of which is attached
by means of a pin joint a rod, S, the lower end of the rod S being attached in a
similar manner to a lever, T, keyed upon the end of a shaft, U, which is also
provided with a pedal, V. Upon the shaft there is a lever, W, and counter-
balance weight sufficient to overcome the friction of the levers, and keep the
catch in the position shewn in the Drawing, in which position it will be.
observed that when the cross head has been raised to the top of its stroke the
catch will take hold of the underside and prevent its returning. When it is
desired to lower the cross head, it will only be necessary for the attendant to

page_text: press with his foot upon the pedal V, which by means of the lever T and rod S
will pull down the lever R, and draw back the catch Q, and thereby release
the cross head which falls down by its own gravity. ✗ is a counterbalance
weight suspended by a chain passing over a pulley, the opposite end of the
chain being attached to the cross head. The object of the counter weight is
to prevent the too rapid descent of the cross head and mandril. Figure 3
represents a plan or edge view of the cross head, shewing the guide bars and
frame sides in section. The action of the machine is simply this:-Motion being
given to the machine by means of a strap, the attendant places his foot upon
the pedal N, so as to raise the mandril; the pipe to be compressed is then held
underneath the mandril, and the cross head released by the attendant pressing
with his foot upon the pedal V; the cross head then descends, and with it the
mandril, which passes through the tube held by the workman. The mandril
having descended so that the end thereof comes between the rollers, the tube is
then lowered, and by the motion of the rollers is drawn over the end of the
mandril, and thereby compressed in the same manner as herein-before described.
Note, the cross head is prevented descending too far by coming in contact with
the brackets C, C. In cases where the tube is required to have a taper
hole, I employ a mandril made taper at the point, as shewn in dotted lines
at Figure 2, the mandril being gradually withdrawn, that is, raised by a
screw or other suitable means, during the time the tube is passing between the
compressing rollers, so that the tube will be made parallel or cylindrical outside,
but with a taper or conical hole.
Another part of my improvements relates to the manufacture of bends for
pipes, and consists, in the first place, of giving the required curve to the bend,
by altering the position of the centre part of the die through which the plastic
material is to be forced. Let a, a, Figure 4, Sheet B, represent a vertical
section of portion of a cylinder technically termed the clay cylinder; b, the die
plate, having a conical opening, as usual; and c, the die; now, so long as the
dic c is concentric with the hole in the die plate a straight pipe will be pro-
duced, that is, if clay or other plastic material be forced through the opening;
but if the die c be moved a little eccentrically, that is, a little on one side, so as
to make the conical annular opening a little larger on one side than the other,
it will be found, on forcing the clay through the die, that a pipe will be pro-
duced of the form of a bend. The mode of setting and regulating the die for
the purpose of producing the required bend is by means of two set screws, d, d,
passing through the lower part of the cylinder, and two bolts, e, e, which are
intended to fix the die in the required position as will be understood. g is a
pillar. for supporting a kind of semi-circular half round trough or guide,

page_text: f, intended to receive the bend pipes as they are forced through the die, which
is effected by means of a piston in the ordinary manner. Bends of various
curves may be made in the manner above described; but when the curve is to
be altered, it will be necessary to alter the position of the die c until the curve
required is obtained, and afterwards place a trough, f, below the die, of the same
curve as the bend to be made, for the purpose of receiving the bends as they
are forced through the die. The bends having being produced in the manner
described, they are then taken to a machine for the purpose of being com-
pressed. The construction of the machine for this purpose will be understood
on referring to Figure 5, and consists of four compressing rollers of the same
form and driven in the same manner as those already described for com-
pressing straight pipes. h is a mandril of cast iron or other suitable material,
made of the same curvature as the pipe to be compressed, the diameter of the
mandril being nearly equal to the internal diameter of the pipe. The mandril
h is made to upon a centre or axis at i, fixed to the framing of the machine,
which framing, in Figures 4 and 5, I have not thought it necessary to shew, as
the same will be understood and readily applied. k is a lever keyed upon the same
axis as the mandril, and is intended to assist the workman in raising the end
h of the mandril above the rollers, so that the bend pipes may be placed upon
the mandril for the purpose of being compressed, by passing through the
rollers, as will be understood. Note, although I have said that pipes are com-
pressed by passing them between four rollers, I would have it understood
that I do not confine myself thereto, as a greater or less number may be employed.
When the article to be compressed differs in form from those, already
described, I employ two, three, or more rollers, as the nature of the
case may require. For instance, if the form be that of a hexagon, I employ
six rollers driven by two spur wheels, and five pairs of bevil wheels, as
shewn at Figure 6, or the same may be done with three rollers. Figure 7
shews a plan of and mode of driving three rollers intended to compress oval
pipes for drains and other like purposes. Figure 8 shews a plan and mode of
driving three rollers for compressing a stair's tread or step of earthenware, to
be used for building purposes. Figure 9 shews another mode of arranging the
rollers for compressing a stair's tread or step. The rollers A and B, for the
top and front of the stair's tread, are supposed to be engraved upon their peri-
pheries, so that an ornamental step will be produced. It will be seen, on
inspecting Figures 8 and 9, that the rollers may be arranged in various ways.
I would therefore have it understood that I do not confine myself either to
the number of rollers employed, or the peculiar shape, pattern, or position of
such rollers, as the same may be greatly varied. Figure 10 represents a plan

page_text: and mode of driving four rollers for compressing the particles of matter of
which hollow bricks or tiles are composed. The two rollers a and b may have
their peripheries cut or engraved with any suitable pattern, which will be im-
pressed upon the sides of the brick or tile. The two rollers c and d are made
with an external and internal rabbet, so that the edges of the bricks, when
moulded, may fit one into the other. The ends of the bricks are also rabetted
in like manner, but in a separate machine, to be described hereafter. Figure 11
shews an isometrical view of one of the bricks made in the manner herein-
before described, also the mode in which they join or come together, which is
represented by dotted lines. Note, the hollow brick as shewn in the Draw-
ing is supposed to have been compressed upon two square mandrils; but
mandrils of any other shape or number may be employed for the purpose of
compressing hollow bricks or tiles. When the article to be compressed is of
a taper or conical form, as a pillar or column, I employ cams or eccentric or
convolute rollers, depending upon the form of figure to be rolled, see Figure 12,
and so on with any other form or figure of article the strength of which it is
desirable to increase by the process of rolling, and thereby consolidating its
particles, as herein-before described.
My improvements in machinery to be employed in the manufacture of pipes
also relate to certain apparatus for forming screw, socket, or rabet joints upon
the end of the pipes. Figure 1, of the sheet of Drawings marked C, repre-
sents a side elevation, and Figure 2 an end view, of a machine for forming
socket or rabet joints. a, a, represents the framework of the machine, which is
similar to an ordinary turning lathe; on the top of the lathe bed there is bolted
two headstocks, b, b, each provided with a spindle, driven by means of a gut or
band, and upon the end of each spindle is fixed a tool-holder, shewn separately
upon a larger scale at Figures 3 and 4. Figures 5 and 6 shew different views
of the tools, drawn full size. The mode of fixing the tools in the tool-holder is
by means of two set screws c, c, which bind against a loose piece of flat iron
or steel d, fitted into a groove formed in one of the projecting arms e, of the
tool-holder, so that by inserting the tool into a slot formed by the two projecting
arms e, e, and turning the screws c, c, the plate d will be forced against the flat
side of the tool, and the same will be held fast in any required position. f.f, are
two bell crank levers moving upon a centre at g. The upper end of these levers,
which are made to embrace the spindle, come in contact with a roller h. To
the lower end of each of these levers f, f, there is attached a rod i, the lower
end of the two rods i, i, being attached to a pedal j. k, k, are two springs
bolted to the end of the headstocks b, b, the upper end of each spring being
made to embrace the end of the spindle. 6, 1, are two bolts attached to a cast

page_text: iron plate, m, bolted to the bed of the machine. These bolts support at their
upper end a cross bar, n, and two flat pieces of wood, o, o, joined together at an
angle of forty-five degrees or thereabouts. The object of this cross bar, which
is capable of being adjusted by means of the screwed bolts l, l, is to support
the pipe during the operation of forming the rabets, which is as follows, that
is to say: rotary motion having been given to the spindles, the workman places
a pipe upon the two bearings o, o, and by pressing with his foot upon the pedal
'the two spindles with their cutters will, by means of the bell cranked levers
be forced simultaneously against the end of the pipe. During this operation
one of the cutters will commence forming the rabet, another will square up the
shoulder at the bottom of the rabet, and the third will square up the end of
the pipe, both ends being done at the same time. The rabet having been cut
to the
proper depth, the workman takes his foot off the pedal, and the springs
k, k, force back the spindles and cutters ready for cutting the next pipe.
Figure 7 represents an elevation and Figure 8 a plan of a machine for
cutting the rabets on bend pipes, and consists of a cast iron frame with two
headstocks, spindles, and cutters similar to those last described. The head-
stocks in this case are bolted at right angles to the bed, and are capable of
moving upon in the direction of the length of the bed, and being fixed by
means of a bolt or bolts to any part thereof, so as to suit any size of bend pipe
to be operated upon. c is a cast iron plate bolted on the top of the bed a, a.
b, b, are two arms of cast or wrought iron, having a
centre pin or stud upon
It will be seen that the
arms b, together with the
the underside, which fits into a hole bored in the end of the plate c. Each of
these arms, which are supported at the outer end by a semi-circular framing d,
bolted to the side of the bed, is provided with a slot into which is bolted the
brackets or bearings I, I, for supporting the pipe.
screwed bolts or bearings 1, 1, and the slots in the
moveable headstocks, admit of those several parts being adjusted to suit dif-
ferent sizes of pipes. The action of the machine is as follows:-The bent pipe
being placed upon the bearing bolts 1, 1, as shewn, the end of the pipe is
brought against the revolving cutters by moving the arms b, b, upon their
centre, by means of the handle 6. fis a stop for regulating the depth to
which the rabet may be cut. When the rabet has been formed upon one end
of the pipe, the two arms b, b, are moved round upon the centre, so as to bring
the other end of the pipe against the revolving cutters of the other headstock,
one series of cutters being set for the external and the other for the internal
rabet. Note-It is desirable to remark that there is a slight discrepancy in
the Drawing just described, inasmuch as the headstock marked x is placed in
the Drawing too near the centre or plate c.

page_text: Figure 9 shews an elevation and plan- of- a machine for cutting screws upon
the end of earthenware pipes. In these Figures, b represents a headstock bolted
upon the bed a of the machine. c is a pulley keyed upon a spindle, which
runs loosely in the headstock, and through a pinion, d, and screw, e. f is a lever
moving upon a centre at f¹. The upper end of this. lever, which fits between
the boss of the pulley and a fixed collar, is made to embrace the spindle, so
that by pressing upon the end of the lever f the spindle will be made to move
in a direction of its length, and with it the cutter g, which is intended to cut
the socket or rabet upon the end of the pipe. f" is a counter weight, for
bringing back the spindle to its original position. The socket having been cut
in the manner described, the next operation is that of cutting the screw. For
this purpose there is a wheel, h, provided with a handle that takes into and
drives a pinion fixed to the end of the screw e, which is of the same pitch as
the screw to be cut. To the outer end of the screw e is attached a cutter, i,
so constructed and arranged that it can be moved out of the way of the cutter
g until the socket is cut. For this purpose it will be seen that the V tool, i,
for cutting the thread, is made to move upon an axis or centre at one end, and
is acted upon by a spring, k, (see plan,) so as to keep the tool either in the
position shewn in the plan or elevation. When it is in the position shewn in
the elevation, it is ready for cutting the screw upon the end of the pipe, which
is effected by giving one turn to the handle of the wheel h, which, by means of
the pinion, gives motion to the screw, and thereby causes the V tool to turn
round, and at the same time advance, so as to cut the screw upon the end of
the pipe.
When cutting internal screws, I prefer the machine to be so con-
structed that the pipe may be in a vertical direction, so that the cuttings,
which have a tendency to chip off portions of the thread of the screw, may
readily drop out. The rabetting formed upon the ends of the bricks is effected
by a revolving cutter or cutters, the brick being slided upon a bench and
against a guide similar to a circular saw bench, with this difference, that
suitable cutting tools are employed instead of circular saws.
Sheet C, shews the mode in which the pipes are joined together.
Having thus described the nature of my Invention, and the manner in which
the same is to be performed, I would have it understood that the combination
and arrangement of the several parts comprising the machines herein-before
described may in many instances be altered so as to produce the same effect
in another way. I therefore do not confine myself to the details herein-before
described, so long as the peculiar character of my Invention be retained.
Neither do I claim as my. Invention the combination of four rollers, and mode
of driving, as represented at Sheet A, Figure 5, the same having already been
Figure 10,

page_text: applied in the manufacture of iron pipes. But that what I do claim as my
Invention is-
First, the application of rollers turned of such a form and arranged in such
a manner that they may be employed for compressing or consolidating the
particles of matter composing pipes, tiles, bricks, copings, stair heads, pillars,
columns, or other articles composed of plastic materials intended for building,
draining, and other purposes..
Secondly, I claim the general arrangement and combination of parts com-
posing the machines for making and compressing pipes as herein-before
described.
Thirdly, I claim as my Invention the mode of making bends for pipes or
bend pipes, by placing the centre part of the die eccentrically with the hole in
the die plate, as herein-before described. I also claim the mode of compressing
in a separate machine the particles of matter of which the bends are composed,
as herein-before described.
Fourthly, I claim the general arrangement and combination of parts com-
posing the machines for forming rabet or socket and screw joints to the ends
of pipes, together with the mode of cutting rabet joints upon the ends of hollow
bricks or tiles.
