Figure 2.
The operation of this apparatus is as follows, that is to say The machinery
being set in motion by operating the shipper lever L the cylinder F is filled with
the candy paste or other plastic material to be operated upon, when the action of
the spiral blade V' upon the said material forces it downward, and compacts it in
the chamber E and around the screws G, G, and they in turn acting upon the com-
pacted mass force it horizontally through the cylinders F¹ and discharge it through
the nozzles c, c, upon the board D, into the grooves h, h, of which it falls, and is
moved away from the said nozzles just as fast as it is delivered therefrom, the
material being severed at the end of each board D which is removed from the machine
with the candy thereon in order that the latter may harden.
Referring to Figures 4 to 14 which illustrate the second part of this invention, A.
indicates the table or bed of the machine supported upon the frames B, B, connected

The front end of the cylinder D has formed thereon a male screw thread, to
which is fitted the conical discharge nozzle D' and the rear end of the said
cylinder D' has secured therein the inwardly projecting flange or collar b as shown
in Figures 7 and 8.
The receiver cylinder E also has formed in one piece therewith a similar
horizontal cylinder E¹ of somewhat smallar diameter than the cylinder D¹ but in
axial line therewith, and extending beyond the cylinder E upon opposite sides
thereof closing the lower end of the cylinder E, and communicating therewith upon
its upper side substantially as shown and described in regard to the cylinder D¹, the
rear end of the said cylinder E¹ being partially closed by the annular head c, as
shown in Figures 7 and 8.
F, F, indicate frames, secured to the upper ends of the receiver cylinders D and E
one to each, and each having formed in its cross-bar a bearing to receive the
pendent shaft G, upon the lower end of which is firmly secured the screw piston H,
the periphery of the spiral blades of which just fits the interior of the receiver
cylinder in which it is mounted and arranged to revolve.
Each of the shafts G is provided with a collar d, which bears against the cross
bar of its frame F and takes the upward thrust of the said shaft; and has secured
to its upper end a bevel gear wheel I which bears upon the upper side of the
cross-bar of the frame F as shown in Figures 6 and 7.
J, J, indicate hollow or sleeve shafts mounted upon the shafts G and each having
formed upon its lower end a screw piston J' similar to the screw piston H, except
that the spiral blade of the screw is wound in the opposite direction to that on H,
or in other words one of the said screws has a right hand thread, and the other a

bevel gear wheel J².
K. indicates a cylinder open at both ends, and having an interior diameter
corresponding to the interior diameter of the cylinder E' with which it is connected
at its rear end by a slip joint shown at e Figures 7 and 8. and having a bearing
in the collar b and provided just in front of the said collar b with an outwardly
projecting collar or flange f, between which and the collar b is placed the annular
washer g to take the rearward thrust of the said screw cylinder. The exterior of
the cylinder K in front of the flange f has formed thereon a double right hand
spiral thread h, the periphery of which just fits the interior of the cylinder D', and
in the rear of the cylinder D₁ it has secured thereon a bevel gear wheel K' by which
it may be revolved.

page_text: Lindicates a second screw, provided with a double left hand spiral thread i,
having its bearings in the head c of the cylinder E' in the said cylinder and the
hollow screw cylinder K, in which latter it is revolved in a direction opposite to
the revolution of the screw cylinder K, h, by means of the bevel gear wheel L' and
other mechanism to be hereinafter described.
The mechanism for revolving the several screws is as follows, that is to say :-
M indicates the main driving pulley mounted loosely upon the shaft M' and adapted
to be connected to the said shaft and cause it to revolve there with by means of the
shipper lever N and a suitable clutch.
The shaft M' bas secured thereon the two pulleys O and O¹, from which the
crossed belts j and j¹ lead respectively to the pulleys P, and P'. The pulley P is
mounted upon the short shaft P2 having bearings in the boxes P³, P³, and carrying
the spur pinion P which engages with, and imparts motion to, the spur gear
wheel Q mounted upon the shaft Q' which has its bearings in the boxes Q, Q³, and
has secured thereon the pulley Q³ and the bevel pinion Q as shown in Figures 4,7
and 8.
The bevel pinion Q engages with, and imparts motion to, the bevel gear
wheel K', to revolve the hollow screw K, h; and the pulley Q, acting through the
médium of the crossed belt R, imparts motion to the pulley R¹ mounted upon the
hub of the spur pinion R³, which in turn, has its bearing upon the fixed stud R³
and engages with, and imparts motion to, the spur gear wheel R* mounted upon
the shaft R, the latter being mounted in the boxes Re and carrying the bevel
pinion R7 which engages with, and imparts motion to, the bevel gear wheel I upon
the upper end of the screw shaft G which works in the cylinder D.
The shaft R5 also has secured thereon the spur gear-wheel S which engages with
and rotates the spur gear-wheel S₁ mounted upon the outer end of the short
shaft S having its bearing in the frame F; the said short shaft has secured upon
its inner end the bevel pinion S³, which engages with, and imparts motion to, the
bevel gear-wheel J' to revolve the hollow screw shaft J within the receiver
cylinder D. The pulley P¹ is mounted upon the hub of the spur pinion T, which
has its bearing upon the stud k, and engages with, and imparts motion to, the
spur gear-wheel T' mounted upon the short shaft T2 having its bearings in the
box T³, and having secured thereon the pulley T and the bevel pinion T5, which
latter engages with the bevel gear wheel L' to revolve the screw L as shown in
Figure 8.
The pulley T acting through the open belt Te imparts motion to the pulley U
mounted upon the hub of the pinion U₁, which has its bearing upon a fixed stud
and engages with and imparts motion to the spur gear wheel U mounted upon
the shaft Us having its bearings in stands or boxes upon the frame F secured to
the cylinder E and having secured thereon the bevel pinion U which engages with
the bevel gear wheel I to revolve the screw piston G, H in the receiver cylinder E.
The shaft U also has secured thereon the spur gear wheel V which engages with
and imparts motion to a similar wheel V₁ mounted upon a short shaft V2 which
has its bearing in the frame F secured to the top of the receiving cylinder E and
has secured upon its inner end the bevel pinion V³ which engages with the bevel gear
wheel J2 to revolve the hollow screw piston J within the receiving cylinder E.
The upper portions of the receiving cylinders D and E are jacketed so as to
form annular chambers D³ and E³ surrounding the same, into which steam, hot air,
or water may be admitted through the pipes m and n, discharge pipes o and p,
being provided as a means of keeping up the circulation of the heating medium,
and discharging from the said annular chambers any water that may accumulate
therein from the condensation of the steam.
W indicates a removable conical discharge nozzle secured to and revolving with
the hollow screw K, its discharge orifice being somewhat in the rear of the orifice
of the nozzle D' and of a somewhat smaller diameter.
X indicates a supplementary nozzle fitted within the orifice of the nozzle W, for
use when it is desired to give to the central core of the moulded article an

page_text: ornamental shape or design, and it may be made as shown in Figures 9 and 10 or
of any other desired design, as for instance the central bub r and the radial
arms 8, 8, may be dispensed with, or it may be a flat disc with one or more
ornamental openings cut therethrough, as shown at a' in Figures 11 and 12; or a
disc with a series of tubes projecting therefrom and surrounding the openings in
the said disc as shown in Figures 13 and 14 in which ✗₁ is the disc, 8 the
openings through the same, and t the tubes surrounding the said openings and
projecting from the radial face of the disc.
Again the orifice through the nozzle D' may be circular as shown in Figures 7
and 8, or corrugated like the nozzle X or any other desired shape according to the
exterior form that it is desired to give to the stick of candy or bar of soap.
In the modification of this part of the said invention illustrated in Figure 11 the
front end of the hollow screw K has screwed therein the ring K³ provided with the
inwardly projecting annular lip or shoulder t¹, within which is fitted by a slip joint
the short tube K³ provided at one end with the outwardly projecting flange u and
at the other end with the inwardly projecting flange u² the latter flange serving as an
abutment to support the perforated disc X' with or without the projecting tubes t,
shown in Figures 13 and 14.
D indicates a short tube, which may be circular or of any other desired shape in
cross section, is secured in a fixed position in the orifice of the conical nozzle D³,
and has cast in one piece therewith the ring v connected to the said tube by the
arms v¹, v¹ the said ring being fitted closely upon and secured by the set screw w to
the outer end of the tube K2, all being so fitted and arranged that the tubes D' and
K² remain stationary while the ring K¹ in the end of the hollow screw K revolves
around the tube K².
If it is desired to produce a stick of confectionery or a bar of soap having
a circular centre of one color, covered by an envelope of even thickness of another
color the cylinders D and E are supplied with the necessary material in a plastic
state, and of the desired color and the disc X' is removed, then, if the several
screws are set in motion, the paste placed in the cylinder E will be discharged
through the tube K' to meet at the end of said tube, and be enveloped by an
annular mass of the paste placed in the cylinder D, the two bodies of plastic
substance being forced together through the tube D, the outer body being
compacted and pressed upon the inner body and made to adhere thereto by such
passage.
If it is desired to produce a stick of confectionery, or bar of soap having a
cylindrical exterior of one color and an interior composed in part of the same
color and in part of another color, the disc X¹ is inserted in the mouth of the
tube K² the said disc having cut through it a series of openings, such as are
shown in Figure 12 or of any desired shape, through which a series of bars or
sticks of paste of one color are forced to be united, as before described, with a
paste of another color, which envelopes each individual stick or bar filling the
spaces between them, and filling the tube D' as before.
If the paste being used is quite soft the openings in the disc X¹ will need to be
prolonged by means of tubes surrounding them and projecting from the outer face
of the said disc as illustrated in Figures 13 and 14, in order that the several rings
of paste being forced through the said openings shall be supported in substantial
parallelism until they are enveloped by the other colored paste coming from the
cylinder D.
The screw L has an axial hole ¹ extending through its entire length the object
of which is twofold, that is to say ;-In some cases I propose to pass through the
said hole from the rear to the front a strip of paper or other material having
printed or otherwise marked thereon a series of mottoes, which strip is drawn
through the said hole by the passage of the plastic material being delivered through
the tube K2, the disc X² having been previously removed therefrom, and thus the
series of mottoes are incorporated in the centre of the stick of confectionery.
In the manufacture of certain other kinds of confectionery I propose to couple

page_text: the rear end of the screw L to mechanism adapted to force a jet of cold air through
the centre of the said screw, for the purpose of cooling the paste at the front end
of the machine, or at the point where it is being shaped to the desired form.
Referring to Figures 15 to 23 which illustrate another part of this invention. A.
B. and C indicate three vertical cylinders arranged side by side with their upper
ends firmly secured in the plate D. Each cylinder is provided at its open upper
end with a short funnel e to facilitate the introduction of paste thereto and
contains at or near its lower end a screw E for feeding the paste downward, the
said screws being secured upon the lower ends of the three vertical shafts E' E¹ E¹
having bearings in the horizontal bar F and provided at their upper ends with the
bevel gear wheels E2, E2, E2, as shown. Each of the said shafts E' is provided
with a collar d secured thereon beneath the bar F the said collars serving to
prevent the shafts E¹, E¹, E' from being thrust upward by their respective screws.
The bevel-gear-wheels E, E engage with corresponding bevel-gear wheels G, G,
secured upon the horizontal driving-shaft H mounted in bearings H'. H. secured to
the plate D, and are provided at one end with the driving-pulley H which may be
revolved by a suitable belt H³, shown in dotted lines in Figure 17.
I indicates a short horizontal tube or central hub having three short tubes A¹,
B and C projecting radially therefrom in different directions, as shown, the
tube A', being connected by the elbow A' to the bottom of the cylinder A. the
tube B' to the bottom of the cylinder B, and the tube C by the elbow C³ to the
bottom of the cylinder C.
In the interior of the hub I are formed three circumferential grooves a-b and c
at about equal distances apart and surrounding the tube J, which passes through
the hub I (accurately fitting the same) and is adapted to have a column of sugar
paste or other plastic material forced through it in the direction indicated by the
arrow Figures 16 and 17.
The groove a communicates by the opening a¹ with the tube A¹ Figure 16 the
groove b communicates by the opening b¹. Figures 15 and 17 with the tube B¹, and
the groove c by means of the opening c' Figure 16 with the tube C¹
Three series of holes a² b and c are drilled through the sides of the tube J and
communicate respectively with the three grooves ab and c
The cylinders A B. and C being filled with paste of the proper consistency, and
each cylinder containing a different color, if the driving mechanism be set in
motion to revolve the screws E, E, E in the proper direction, the paste contained
in the cylinder A will be gradually fed downward through the elbow A2, tube A¹
and opening a' into the groove a, and thence through the holes a³, and deposited
in lines or stripes upon the exterior of a column of paste which is being fed
through the tube J. In the same manner the paste in the cylinder B will be fed
down through the tube B₁, and opening b' into the groove b, and through the
holes to form longitudinal stripes of another color, and the paste from the
cylinder C will be fed through the elbow C, tube C', opening c¹, groove c, and
holes c² to form stripes of still another color, and thus the column of paste which
passes through the tube J will issue therefrom having upon its exterior surface a
series of longitudinal stripes of different colors arranged at such distances apart
and in such order as may be determined by the position of the holes a². 62 and c²
in the suid tube J.
The number, width or circumferencetial order of the stripes may be varied by
changing respectively the number size or position of the holes a b³ and c² and the
colors may be varied as desired. In the apparatus shown in the drawings three
cylinders are employed but one, or more may be employed as may be desired.
The machine as shown in Figures 15, 16 and 17 is adapted for producing fifteen
stripes of three different colors five stripes of each color, the arrangement of the
said stripes being indicated in Figure 21 which represents an enlarged end view of
a stick of confectionery, the stripes being equal distances apart, and the colors
arranged in regular succession around the circumference. The paste from the
cylinder A passing through the groove a and holes a produces the stripes a³ the

page_text: paste from the cylinder B passing through the groove b and holes 62 produces the
stripes 6; and the paste from the cylinder C passing through the groove c and
holes produces the stripes c³.
Figures 18, 19 and 20. illustrate the method of introducing lines or stripes of
one or more colors to the interior of a column of sugar paste or other plastic
material.
A small tube a* extends diametrically across the tube J and communicates at
each end with the groove a. The tube a is provided with a hole or opening a³ in
the centre of its length and concentric with the axis of the tube J, and with two
other holes a, a, between the hole a³ and the ends of the tube a*. Two other
tubes a, a extend inward towards the centre of the tube J at right angles to the
tube a³. They are each provided at their inner ends with an opening a upon one
side thereof and communicate at their outer ends with the groove a.
The groove c,
also communicates with the outer ends of four tubes c projecting inward towards
the centre of the tube J and each having an opening c upon one side at its
inner end
The paste fed to the groove a passes into the tubes a and a into the interior of
the tube J, and the paste from the groove c passes into the tubes c* and is delivered
at the openings c, and the column of paste which is being forced through the
tube J around the various small tubes above mentioned will surround and envelope
the lines of paste issuing from the said openings and be delivered from the tube J
with a series of longitudinal stripes or lines of one or more colors extending
through the interior thereof.
Stripes of different colors may at the same time be placed upon the exterior of
the stick of paste by means of the openings a² communicating with the groove a,
the openings 6 communicating with the groove b and the openings c² communicating
with the groove c in the manner as previously described.
The design produced by this especial arrangement of holes and tubes is illustrated
in Figure 22 and the operation is as follows; that is to say, the paste which is fed
from the cylinder A to the groove a will pass through the tubes a and a' and
openings a and a, and form the four interior stripes as Figure 22 and the central
interior stripe a³, while the paste which enters the holes a² will form the four
external stripes a³; the paste fed from the cylinder B to the groove b will enter the
openings 62 to form the eight exterior stripes 63; and the paste fed from the
cylinder C to the groove c will pass through the tubes ct and openings c5 and form
the four interior stripes c, and the paste which passes through the holes c² will form
the four exterior stripes c³
I have described the particular design which the machine, as shown in the
drawings, is adjusted to produce but it is obvious that the number and position of
the tubes for producing the internal stripes may be varied; the number, shapes and
sizes of the openings in the said tubes may be changed; the colors of the paste may
be varied as desired; and an almost unlimited number of combinations and designs
produced. The tube J is adapted to be connected with a suitable machine arranged
to force paste through the said tube as illustrated in Figure 17. Upon one end of
the tube J is secured the flange f surrounded by the swivel coupling ring g, which
may be screwed upon the end of the horizontal cylinder or tube K to connect the
tube J therewith.
A portion of a vertical cylinder L is shown provided with a suitable screw M for
forcing the paste contained therein downward to the screw N which is arranged to
force the paste through the horizontal cylinder K in substantially the same manner
as bereinbefore described
This part of the said invention is applicable to either of the machines shown and
described in the former part of this specification
The tube J is provided at its outer end with the screw-thread h for the purpose
of attaching thereto, a device for twisting the sticks of plastic material, which device
forms no part of this invention. A shoulder is formed upon the tube J as a
means of fixing the proper position of the said tube within the hub I by coming in

page_text: contact with the end of the hub I when the series of openings in the tube J, are
opposite the respective grooves in the said hub.
In Figure 23 is illustrated a method of coating the entire surface of a stick of
sugar paste of one or more colors with paste of another color instead of covering it
partially by striping as before described. In this case only one of the cylinders
A B or C would be used as for instance the cylinder B. The tube J is divided at
a point within the hub I where the groove b is situated, and the ends are separated,
as shown, so that the groove b communicates throughout its entire circunference
with the interior of the tube J, and the paste fed into the groove b will surround
the column of paste passing through the tube J and deposit upon the entire surface
thereof a coating of even thickness. The openings through the tube J commu-
nicating with the grooves a and c may be dispensed with.
Having thus fully described the said invention as communicated to me by my
foreign Correspondent and the manner of performing the same I wish it understood
that I claim in a machine for moulding or shaping plastic material
