IMPROVEMENTS IN MAKING CLAY TOBACCO PIPES AND IN APPARATUS THEREFOR.
Year: 1875

page_text: LETTERS PATENT to Richard Golding, of Tooting, in the County of
Surrey, Tobacco Pipe Maker, for the Invention of "IMPROVEMENTS
IN MAKING CLAY TOBACCO PIPES AND IN APPARATUS THEREFOR.'
"
PROVISIONAL SPECIFICATION left by the said Richard Golding at the
Office of the Commissioners of Patents, with his Petition, on the
11th August 1875.
I, RICHARD GOLDING, of Tooting, in the County of Surrey, Tobacco
Pipe Maker, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MAKING CLAY TOBACCO PIPES AND IN APPARATUS THEREFOR,"
to be as follows, that is to say :-
This Invention has for its object the making of clay tobacco pipes in
a better and more economical manner than has been hitherto attained.
In carrying out the Invention according to one modification, a "roll"
or rough pipe block is first formed in one mould or pair of half moulds,
and is afterwards transferred to and finished in a second mould, in

page_text: another modification however the moulding is all performed in one
mould. An important feature of the Invention is the adaptation of the
apparatus for using clay of extreme stiffness, and thereby producing
pipes of great strength.
The clay carefully prepared in any suitable known way is first formed
into bars of any convenient shape, by being forced through dic orifices
out of a cylinder by means of a piston or plunger worked by a screw
or by hydraulic power. A bar of the clay is placed in the moulding
machine, and at regular intervals short lengths or blocks are cut off and
deposited in front of the mouth of the mould. Each block is forced into
the mould by a piston or plunger which is moved by levers, screws, or
cams, or by hydraulic apparatus, so as to exert very great pressure on
the clay. The mould is made in two halves which are gripped firmly
together by means of screws, cams, levers, or hydraulic apparatus
during the moulding operation. The bowl part of the mould is shaped
as plainly as possible, and a considerable part of it from the mouth
inwards is made truly cylindrical (or it might be prismatic), so that the
plunger works in it like a close fitting piston in a cylinder. The
pressure of the plunger on the clay in the bowl part causes the clay to
fill into the stem part of the pipe, and the completion of the forcing
process is known by the clay reaching the end of the stem. The clay is
at once moulded in a tubular form in consequence of a wire being held
in the mould whilst the clay is being forced in. This wire is entered at
the bowl end through a tubular plug, the inner end of which tubular
plug projects into the bottom of the bowl part during the most part of
the forcing operation. Near the end of the operation however the plug
is drawn sufficiently far outwards for its inner end, which is suitably
shaped, to become flush with the interior of the bowl part. The wire is
also withdrawn through the plug, but is followed by another wire which
is entered from the other end, this second wire serving to lift the roll or
pipe out of the mould, which it does by turning upwards to a convenient
inclination for withdrawing the pipe or roll off it by hand. When a
second mould (or pair of moulds) is used for completing the shaping of
the pipe, such second mould is placed conveniently near the first, so that
the roll can be deposited in it immediately on being drawn off the wire
of the first mould. The second mould is closed and gripped like the first,
and a "stapper" is forced into the bowl part, a third wire being entered
up the stem to prevent it from closing up, and being pushed forward

page_text: into the bowl as the stapper is being withdrawn to insure an opening
into the bowl.
When moulding the pipe entirely in the first mould the piston or
plunger is formed with a stapper-shaped front, or a stapper is forced
through the piston (made annular) after the piston is forced in a certain.
distance, or the piston may be withdrawn and a stapper be forced into
the same mould afterwards, whilst a part of the mould with the cylin-
drical portion of the bowl part may be separable to facilitate the
secondary introduction of the stapper. It is however preferred to shape
the pipe at two operations in different moulds, unless the bowl part is of
a very plain form.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Richard Golding in the Great Scal Patent Office
on the 10th February 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
GOLDING, of Tooting, in the County of Surrey, Tobacco Pipe Maker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing dato the Eleventh day of August, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Richard Golding, Her special
licence that I, the said Richard Golding, my executors, administrators,
and assigns, or such others as I, the said Richard Golding, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MAKING CLAY TOBACCO PIPES AND IN APPARATUS THErefor,” upon the condition
(amongst others) that I, the said Richard Golding, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain
the nature of the said Invention and in what manner the same was

page_text: to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Richard Golding, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement in writing, reference being had to the accom-
panying Drawings, that is to say :-
My said Invention has for its object the making of clay tobacco
pipes in a better and more economical manner than has hitherto been
*attained.
"roll"
In carrying out my Invention according to one modification a
or rough pipe block is first formed in one mould or pair of half moulds
and is afterwards transferred to and finished in a second mould; in
another modification, however, the moulding may be all performed in
one mould. An important feature of my Invention is the adaptation of
the apparatus for using clay of extreme stiffness, and thereby producing
pipes of great strength.
The clay carefully prepared in any suitable known way is first formed
into bars of any convenient shape by being forced through die orifices
out of a cylinder by means of a piston or plunger worked by a screw or
by hydraulic power. Short lengths or blocks are cut off the clay bar in
succession, and cach block is forced into the "roll" mould by a piston
or plunger moved so as to exert very great pressure on the clay. The
pressure of the plunger on the clay in the bowl part of the mould
causes the clay to fill into the stem part, where it is at once moulded in
a tubular form in consequence of a wire being held in the mould at the
time. The same wire, or a second wire substituted for it at the end of
the forcing operation, is made to turn the roll up out of the mould in a
manner facilitating its transference to the second or finishing mould.
The apparatus is contrived so that the various movements of its parts
are derived from a first motion revolving shaft through suitable gearing
operating by cams or wipers on levers and other parts.
And in order that my said Invention, and the manner of performing
the same may be properly understood, I hereunto append five Sheets of
explanatory Drawings, to be herein-after referred to, and representing
one modification of my improved tobacco pipo moulding apparatus. In

page_text: these Drawings the same reference numerals and letters are used to
mark the same or like parts wherever they are repeated.
Figure 1 on Sheet 1 of the Drawings is a plan of the machine, but
with various parts removed partly to avoid repition and partly to
facilitate the explanation of parts which could not be properly shown
otherwise.
Figure 2, Sheet 2, is a back elevation, and Figure 3, Sheet 3, is a front
clevation, both as with parts removed.
Sheet 4 comprises enlarged views of the slide or carriage, and
other parts, and Sheet 5 comprises separate views of various details.
The first motion shaft 1 of the machine is a horizontal shaft having
loose on it a spur wheel 2 to be driven by a pinion on the crank shaft of
a steam engine or on a shaft driven in any other convenient way, and a
clutch and lever 3 are provided for engaging the spur wheel 2 with the
shaft 1. The shaft 1 is carried in bearings in the framing of the
machine, and has fast on it a spur toothed wiper disc 4 which gears with
a similar spur toothed wiper disc 5 on a parallel horizontal shaft 6.
Most of the parts of the machine are in duplicate and symmetrically
placed towards either end; the various actions take place alternately,
however, there being at each side apparatus for forming a roll and
apparatus for the second or finishing moulding operation whilst all four
moulds are on one slide, which moves alternately towards each end of
the machine. The movements of the mould slide are derived from
wiper studs 7 on the inner or front faces of the discs 4, 5, which studs
act on levers 8 centered on brackets fixed to the framing. The levers 7
are connected by adjustable links 9 to a short lever or boss 10 on a
vertical shaft 11, and this shaft, by means of gearing shown separately
in Figure 10, Sheet 5, and consisting of toothed sectors 12, 13, 14, 15,
gives increased motions to a vertical shaft 16, having fast on it a
grooved pulley 16, which is connected by cords 18 (Figure 1) to the
mould slide 19.
The mould slide 19 is shown separately in plan and front elevation in
Figures 5 and 6, Sheet 4, besides being partly shown in Figure 1. In
Figure 6 the bottom half of each roll mould 21 and the bottom half of
one of the finishing moulds 21 are shown in the positions in which they
are held on the slide, being however free to move vertically to a slight
extent for a purpose herein-after referred to. The mould slide 18 rests

page_text: and moves on two parallel horizontal guide rails 22, 23, formed on or
fixed to the framing; and when the slide is in the position in which it
is shown in Figure 1 the forcing or compressing actions are just being
completed in the moulds 20, 21, at the right hand end, whilst at the
left hand end a completely moulded pipe has been removed from the
finishing mould 21, to which a roll has afterwards been transferred
from the roll mould 20. The mould slide 19 in moving to the right
carries its right hand half roll mould 20 into a box 24 (shown in vertical
section in Figure 3, Sheet 3) and under the upper half mould 25, which
is at the time held up by a counterweighted lever 26 connected to it by
links. As soon as the lower half mould 20 has entered the box 24 the
upper half mould 25 is closed down upon it by the action of a wedge
bar 27, which is then moved to the right. This bar 27 is made with
two blocks, formed at their right hand corners with inclines, which
acting on counterpart inclines on the under side of the cover of the
box 24, and on the top of the upper half mould 25, first cause the
depression of the latter, and then parallel parts of the blocks entering
between corresponding parts of the cover and half mould form a solid
combination capable of resisting a strong pressure that is immediately
afterwards applied for the purpose of gripping the two half moulds
20, 25, forcibly together. The bar 27 is moved by a toggle link 28
jointed to the short arm of a two armed lever 29 carried by a bracket 30
attached to the box 24, the lever 29 being actuated as herein-after
explained. The end of the toggle link 28 that is connected to the
wedge bar 27 is guided by a short radius link. The details acting on
the wedge bar 27 are partly indicated by dotted lines in Figure 3. The
half moulds 20, 25, are gripped together by two short vertical screws 31,
indicated by dotted lines in Figure 3. The half moulds 20, 25, arc
gripped together by two short vertical screws 31, indicated by dotted
lines in Figures 1 and 3, and shown in a separate sectional view in
Figure 9 (Sheet 5). Each screw 31, or circular wedge as it may be
more appropriately termed in this application, is set in a socket
formed for it in the bottom of the box 24, being held up by a
plate bolted on and having in it a screw and jam nut 32 for nicely
adjusting the position vertically of the circular wedge 31. A block 33
movable vertically, but which does not turn, rests on the wedge or
screw 31, its under side being made counterpart to it; and a steel pin
is fixed in the top of this block 33 to bear up against the half mould 20.
The wedges or screws 31 are formed with lever arms 34, 35, connected

page_text: by a link 36, and one arm 34 has attached to it by a swivel joint a
link 37 connecting it to a lever 38, which in Figure 2 is exactly behind
a similar lever 39, the function of which last is herein-after explained.
The levers 38, 39, are centered on brackets fixed to the framing, and
are formed with wings 40 to be acted on by wiper blocks 41, 42, on the
disc 4 or 5, each lever 38 being acted on by the block 41, which is fitted
with a spring blade at the part first coming into action to moderate the
concussion. Slotted links 43 guided on a fixed pin are jointed to the
levers 38, 39, and are connected by links 44, 45, to levers 46, 47, which
are acted on by the wiper blocks 41, 42, so as at the proper times to
move back the levers 38, 39, and parts connected to them. The
powerful action of the screws or wedges 31 grips the two half moulds
20, 25, so forcibly together that the mould can withstand the pressure with
which the clay is forced in as though consisting of a single solid piece.
Before describing the arrangements for placing the blocks of clay
successively into position for being forced into the mould it will be most
convenient to describe the parts for forcing in the clay, premising
merely that each block of clay is at the proper time placed in front of
the bowl orifice 48 of the mould. The block of clay is forced into the
mould 20, 25, by a piston or plunger 49 formed or fixed on the end of
a block 50, which is fitted to slide in a guide box 51 fixed on the
framing. The piston block 50 is moved by a bar or lever 52 jointed to
it by a pin and connected to a bar 53 centered on a short lever 54
indicated by dotted lines in Figure 1. The bar 52 directly connected to
the piston block 50 is connected by an adjustable link 55 to a lever 56
centered on the framing so as to move horizontally, and this lever 50 has
attached to it by a swivel joint an adjustable link 57 which connects it
to one 39 of the levers acted on by the wipers on the disc 4 or 5. At
the time that the clay is being forced into the mould 20, 25, there are
in the mould, as shown at the right-hand side of Figure 5, a tubular
plug 58 and a wire 59, the latter passing through the former and each
attached to a dovetail piece which is movable vertically the one in the
plug holder 60, and the other in the wire holder 62. These parts are
made movable vertically, as is also the half mould 20 itself on pins
which keep it horizontally in place on the mould slide 20 in order to
allow of any upward movement which the gripping screws 31 may
cause. The wire holder 61 is a long bar movable longitudinally on the
mould slide 19, and carrying a wire 59 at each right angled end. It
moves partly with the mould slide and is partly moved thereon by a

page_text: bar 62 formed with two projections 63 entering a slot in it. The bar 62
is itself moved by details, best seen in Figures 15 and 16, Sheet 5, the
latter being a vertical section as at right angles to the former. A
lever 64 centered on the framing is turned up after the mould slide 19
has passed over it, and is made to move the bar further in the same
direction by a lever 65 on the end of a horizontal shaft 66, having fast
on its other end a lever 67 connected by a link to another lever 69,
so centered on the framing as to be encountered by a pin 70 on the end
of the lever 56, herein-before referred to. Each wire 59 is entered from
the bowl end towards the end of the pipe stem in order that the clay in
being forced through the mould may exert a pulling instead of a pushing
action on it, and it is protected against the thrust of the clay in the
bowl part by the tubular plug 58. The wire 59 is withdrawn before the
forcing action of the piston 49 is quite completed, and the tubular
plug 58 is also withdrawn so far as to make its inner end flush with the
side of the bowl part, and the continuance of the forcing movement
causes the clay to completely fill the cavity that would otherwise be left
by the plug. The plug holder 60 is a dovetail bar with right angled
ends, and is fitted partly beneath the wire holder 61 in a guide groove
in the mould slide 19. It is moved by a lever 71 on a small rocking
shaft 72 carried by the mould slide, and this shaft 72 has fast on it two
jointed levers 73 which are acted on alternately by struts 74 moved in
vertical slots in the mould slide 19 by inclines formed on the under side
of the bar 62, which is herein-before referred to as moving the wire
holder 61. The action of the jointed levers 73 can be varied by adjusting
small blocks on which their outer ends rest. The bar 62 also serves for
relieving the mould slide 19 from one of two locking catches 75, which
secures it whilst the moulding operation is being performed at either
end of the machine. This catch 75 is a bolt pressed by a spring 76
through a slot in the framing, so as after being pushed out by an
inclined projection on the mould slide and indicated by dotted lines at 77
in Figure 5 to enter behind such projection. An incline near each end
of the bar 62 acts on a lever 78, best seen in the section Figure S, and
centered on the framing, and this lever 78 moves a bolt 79 so as to turn
a small rocking spindle 80, that by a wiper or small lever acting against
a projection on the under side of the bolt 75, but not shown in Figure 8,
moves that bolt outwards and thereby allows the mould slide to be
moved towards the other end of the machine. The bar 62 is held in
place by a grooved cover A bolted to the mould slide 19.

page_text: As the wire 59 is being withdrawn from the mould 20, 25, it is
followed by another wire S1 which enters at the stem end, being held by
a spindle 82 which moves for the most part with the wire holder 61. so
as to closely follow the first wire 59 along the stem; but it stops short
on reaching the bowl because of a bar 83 fixed to it encountering the
box 24 in which the roll moulding operation takes place. The half
mould 20 has bolted to its inner end a small casting 84, shown separately
in Figure 7 and formed with two cheeks, between which there is a small
cradle S5 formed with trunnions entered into slots in the checks. In
the cradle 85 there is fitted to slide a small tube 86 through which the
wire 81 passes, and which is entered into the stem orifice of the mould
20, 25. The clay on being forced into the mould ultimately reaches the
tube 86, and if there is any surplus of clay it forces the tube out so
that a lug on it encounters and turns a trigger 87 which prevents
further pressure on the clay in a manner herein-after explained. When
the half mould 20 is moved to the middle of the machine the cradle 85
gets upon one of a pair of pieces 88 jointed loosely on the spindle 82,
on which the wire 81 is centered, and the piece S8 is then lifted by a
cam 89, and causes the wire 81 to be turned up with the roll on it into
an inclined position clear of the mould, so that the roll can be easily
drawn by hand off the wire 81, and be transferred to the finishing half
mould 21. The slots in the checks of the casting 84 allow the cradle 85
to turn up, as described. The cams 89 are moved by dovetails, partly
shown in Figure 6, a lever 90 on the small shaft of each cam being con-
nected by a link to another lever 91, on which there is jointed a block
92 fitted to run in a guide groove. The two guide grooves are in fixed
parts 93 of the framing, and are inclined so as to cause the desired
movements of the cams 89 as the mould slide 19 moves from end to
end. The parts acted on by the trigger 87 (Figure 7) are shown in
Figure 4. The lever 54 which carries the ordinarily stationary centre for
the parts acting on the piston block 50 is itself centered on a fixed part,
and has attached to it a quadrant 94 on which there is adjusted and
fixed a lever 95, having jointed to its end a rod 96. This rod 96 is
formed with a notch so as to be held between a fixed stud on a bracket
and a projection forming the shorter arm of a bell-crank lever 97, also
centered on the bracket. The end of the longer arm of the lever 97 is
held out by a strut forming one arm of a small bell-crank lever 98,
and it is on the other arm of this lever 98 that the trigger 87 acts,
so that when there is a surplus of clay in the mould it causes the lever 98

page_text: to turn and release the bell-crank lever 97, whereupon the rod 96 and
lever 95 become free, and any further strain moves out the lever 54
instead of forcing the piston 49 further into the mould.
I
The mechanism for supplying the clay blocks for the roll mould 20, 25,
is shown on Sheet 5, Figure 11 being a plan, Figure 12 an inner end
clevation, and Figure 13 a side elevation. This mechanism is to be
placed upon the guide box 51 of the piston block 50, and it comprises a
horizontal guide 99, on which there is placed a round bar 7 of the clay,
shown by blue lines, such bar being formed of a sufficiently stiff con-
sistency in the manner herein-before described. The bar is moved
towards the mould, that is, to the left hand, as shown in Figures 11, 13,
but at a higher level by rollers c, which are on spindles having pulleys d
on them with cords passed round to cause them all to move together.
The spindle e of one of the pulleys c extends down to a ratchet wheel f
which is acted on by a pawl and lever g; this lever being moved to the
right by a pin h fixed in the piston block 50, and projecting up through
a slot in the top of the guide box 51. The piston block acts on the
pawl lever during the latter half of its traverse from the mould, and
during the first half of its return the pawl lever g is moved to the left
by a spring i, and it is then that the pulleys care turned so as to feed
the clay bar forward to the extent required for a block. When the
bar is thus fed forward its end projects over the end of the bottom of
the guide 99, and over the inner end of the guide box 51, and a length
or block is then cut off it by a pair of knives held by levers turning on
centres m and moved by the wedgewise entrance between the lower ends
of the levers of the piston block 50, this action taking place during the
second half of the movement of the piston block towards the mould.
The block then cut off is supported by blades n fixed to the knife levers
until the piston block 50 moves back again, when the upper end of the
knife levers open by the action of the spring 2 on their lower ends,
and the clay block then drops down between guides so as to be in front
of the piston 49, when the piston block 50 next moves towards the
mould.
The second or finishing moulding operation is effected on one pipe ȧt
the same time that the roll for another one is being formed. The under
half finishing mould 21 is clamped on a plate q fitted upon the mould
slide 19 so as to be slightly movable vertically, and as the slide 19 moves
to the right it is carried into a box 7, in which the upper half mould s

page_text: is closed down upon it by means of a wedge bar t connected to the
wedge bar 27, herein-before described, together with its actuating details,
in connection with the roll mould 20, 25. The toggle link 28 has
jointed to it a horizontal link u, and one pin connects the outer end of
this link to both wedge bars 27, t. The lever 29, by means of which
the wedge bars 27, t, are moved, is acted on by a pin on the lever 38,
and is fast on the back end of a horizontal shaft, which has on its front
cnd the short lever jointed to the toggle link 28. The two half
moulds 21, s, are next gripped together by a vertical screw or wedge w
turned by a lever x connected by a link y to one, 35, of the levers of
the gripping screws 31 for the roll mould. The piston or "stapper"
which forms the bowl of the pipe and at the same time forces the clay
into all parts of the mould 21, s, is attached to a block 100, which
slides in a guide box 101, and is connected by a link to a lever 102,
indicated by dotted lines in Figure 1, and which is itself connected by
an adjustable link 103 to a second lever 104, connected by a link 105 to
the corresponding lever 56 of the roll moulding niovements. After the
stapper is withdrawn any surplus clay at the bowl orifice of the
mould 21, s, is cut off by a knife 106, shown with other details in
Figure 14, Sheet 5, and carried by a lever 107, which is acted on by a
tappet 108 on the stapper slide 100. The knife is fixed to a bell
crank 109 jointed to the end of the lever 107, and as this lever is moved
to the left the bell crank 109 encounters a screw 110, and is thereby
made to fling off any clay it may have cut off. The bell crank 109 and
knife 106 are turned back again by a spring 111. The lever 107 is
moved back by a spring 108.
When the roll has been laid in the finishing mould 21 a wire 115 is
entered up its already hollowed stem, and after the second operation is
completed and the mould moved back to the middle of the machine the
finished pipe may be tilted up by the wire in the manner herein-before
described with reference to the roll. In the Drawings, however,
(Figure 5) the wire 115 is supposed to be attached to the bar 62 herein-
before described for moving the wire holder 61.
In herein-before describing the arrangements for cutting short blocks
off the clay rod bit should have been mentioned that the clay is
supplied with a little oil to prevent its adherence to the moulds, the oil
dripping from a reservoir 116 by two tubes 117, fitted with regulating

page_text: cocks, and one of which drops the oil on a small sponge held by a
spring 118 against the end of the block that is being cut off.
The apparatus shown on the Drawings is contrived so that the
moulds 20, 25, and 21, s, can be changed for other moulds adapted for
pipes differing to a limited extent in shape, and in particular the
necessary parts can be adjusted to suit different inclinations of the bowl
part to the stem. Thus the guide box 51 for the piston block 50
appertaining to the roll mould is upon an arc-shaped piece of the fixed
framing, on which piece it can be bolted in any desired position, and the
levers and links through which the movements of the piston block 50
are effected are made adjustable to suit any position, the centres of the
levers being chosen so that the action may not be affected by any
required change of position. In a similar way the slide block 100 of
the stapper appertaining to the finishing mould works on a plate,
which can be fixed at different parts of an arc-shaped part of the
framing, and the levers and links for working the slide block 100 are
also made correspondingly adjustable.
The bowl part of the roll mould 20, 25, is shaped as plainly as
possible, and a considerable part of it from the mouth 48 inwards is
made truly cylindrical (or it might be prismatic), so that the plunger 49
works in it like a close fitting piston in a cylinder.
When moulding the pipe entirely in the first mould 20, 25, the piston
or plunger 49 is formed with a stapper-shaped front, or a stapper is
forced through the piston (made annular) after the piston is forced in a
certain distance, or the piston may be withdrawn and a stapper be forced
into the same mould afterwards, whilst a part of the mould with the
cylindrical portion of the bowl part may be separable to facilitate the
secondary introduction of the stapper. I, however, prefer to shape or
mould the pipe at two operations in different moulds unless the bowl
part is of a very plain form.
Having thus particularly described my said Invention and the manner
of performing the same, I have to state that I do not restrict myself to
the precise details herein described or delineated, and that I do not claim
to have invented every separate detail or minor arrangement that I
have had occasion to refer to, as some of such details are necessarily
common to any tobacco pipe making apparatus, but that what I believe

page_text: to be novel and original and claim as the Invention secured to me by
the herein-before in part recited Letters Patent is,―
1. The making of "rolls" for forming clay tobacco pipes out of
blocks cut from a bar or rod of stiff clay by means of a pair of half
moulds (20, 25,) shaped as regards the bowl part, and placed, and
gripped, and having working in combination therewith a close fitting
piston (49), all in the manner herein-before described.
2. The forming of the tubular stem of the roll on a wire introduced
from the bowl end, and having combined with it a projecting plug
piece, such wire and plug piece being withdrawn and a second wire
entered from the stem end and made to tilt up the roll, all as and for
the purposes hercin-before described.
3. The combining of cach roll mould with its companion finishing
mould and the several accessories in the manner hercin-beforo described.
4. The herein-before described arrangements for separating or closing
each upper half mould from or upon its under half mould and for
moving the latter horizontally away from the former.
5. The arranging and combining of the parts for working the
piston (49) and stapper (s) and the providing for the adjustment of
those parts to suit different inclinations of the bowl, in the manner
herein-before described.
In witness whereof, I, the said Richard Golding, have hereunto
