Improvements in or relating to Apparatus for the Manufacture of
Confectionery and the like.
(A communication from ALEXANDER G. MCCAUSLAND, of Brantford, in the Pro-
vince of Ontario, Dominion of Canada).
We, WILLIAM KING BAKER, and GEORGE SAMUEL BAKER, both of 58 City Road,
in the County of Middlesex, Engineers, do hereby declare the nature of this inven-
ion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
This invention relates to apparatus for the manufacture of confectionery and
the like, and comprises a machine for delivering plastic candy stock in drops upon
a web of paper whercon the stock is dried for the market, or for ejecting other
stock in like manner to form cakes or "drop biscuits."
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding parts
in all the Figures.
Figure 1 is a side elevation of one construction of machine according to this
invention;
Figure 2 is a cross section thereof taken vertically through the stock reservoir;
Figure 3 is a longitudinal section of the machine with parts omitted;
Figure 4 is a plan view of the same also with parts omitted;
Figure 5 is a plan view of the stock receptacle;
Figure 6 is an enlarged section showing one of the valve devices therefor;
Figure 7 is an enlarged section of the air pump;
Figure 8 is a plan view of the upper head of the cylinder of the air pump;
Figure 9 is a cross section of the cylinder on the line 9-9 of Figure 7, looking
downward from the line of section;
Figure 10 is a section taken transversely of the machine, to show the paper
severing knives; and
Figure 11 is a cross section of said knives.
The frame of the apparatus is rectangular and carries at each end a transverse
roller 10, said rollers being adjustably held on their shafts by means of collars 11,
attached to the shafts at the ends of the rollers. Over the rollers 10 a belt 12
runs. Fixed to the shaft of one of the rollers 10 is a ratchet disc 13, with which a
pawl 14 co-acts, the pawl being carried by an arm 15 swinging on the shaft of the
ratchet disc, and operated by a link 16 having cranked connection with a spur
gear 17. The spur gear 17 is mounted loosely on a stub shaft held on the frame
of the apparatus and gears with a driving spur gear 18 held on the primary move-
ment shaft 19, which passes transversely through the frame at the middle thereof.
By these means the rollers 10 are driven intermittently, and the belt 12 made to
travel horizontally between the side portions of the frame.
Sliding between vertically extending guides 20 held by the sides of the frame,
is a table 21 located beneath the upper run of the belt 12 and approximately at the
centre of the frame. The shaft 19 passes beneath the table 21 and carries two

page_text: cams 22.
As the shaft 19 revolves the cams 22 act simultaneously on the table 21
to raise and lower the same in its guides 20, as indicated by the dotted lines in
Figure 3. This causes a regular rise and fall of the upper run of the belt 12;
and the operation of the parts is so timed that as the belt rises the candy stock
will be deposited upon the belt in a manner to be hereinafter described.
The candy stock is held in a reservoir 23, formed with cylindrical sides, joined
to heads 24 and 25 by means of bolts 26, passing between lugs on the heads 24
and 25 and into annular bands 27 attached to the sides of the reservoir. The
reservoir is held rigidly midway of the frame and above the same, by means of
trusses 28 rising from the sides of the frame and rigidly secured thereto. The
top head 24 of the reservoir has a central opening surrounded by a flange 29
having an annular groove formed in its outer face. The opening in the head 24
is normally closed by a plate 30 held down by a hand screw 31 working in a
yoke 32, the ends of which engage in the groove of the flange 29. The reservoir 23
also has a pressure gauge 33 indicating the amount of pressure in the reservoir.
The head 25 tapers downward on the principle of funnel, and has a transversely
elongated lower extremity provided with a series of transversely aligned outlet
tubes 34, each of which is normally closed by a valve 35, which valves are attached
to stems 36 located within the reservoir and guided by a frame 37 secured in the
head 25. A rock shaft 38 runs transversely through the head 25 and carries a
series of arms 39 respectively connected with the valve stems 36. One end of
the shaft 38 projects beyond the corresponding truss 28, and carries a crank arm 40
to which a link 41 is adjustably connected, said link having a cranked connection
with a spur gear 42 mounted on a spur shaft carried by the frame and meshing
with the driving spur 18. By these means the arms 39 are raised upward to
simultaneously lift the valves 35, whereupon the stock within the reservoir 23 may
be expelled through the tubes 34.
The candy stock is forced from the reservoir by air pressure continually main-
tained within the reservoir. This pressure is produced by a pump, shown in
detail in Figure 7, and consisting in a cylinder 43, with an open upper head 44
and a valved lower head 45. Moving within the cylinder 43 is a piston 46 having
a rod 47 pivotally connected therewith. The lower edge of the piston 40 has a
rabbet groove 48 containing a suitable packing ring 48 held rigidly in place by a
plate 49 bolted or otherwise rigidly secured to the lower face of the piston 46.
The piston rod 47 is pivotted to a link 50 that runs upward and has cranked con-
nection with the gear wheel 18. By these means the piston 46 is reciprocated
within the cylinder 43 and air compressed within said cylinder. The air from the
cylinder 43 passes through a check valved pipe 51 to a container or trap 52 that
is rested on the floor beneath the frame of the apparatus. From the container or
trap 52 a pipe 53 passes upward to the upper portion of the reservoir 23. The
pipe 53 has a reducing valve 54 by which the air is made to enter the reservoir 23
under pressure reduced beyond that in the container or trap 52. A pressure
gauge 55 is in connection with the container or trap 52 whereby to indicate the
pressure therein. By this construction I am able, upon the raising of the
valves 35, to simultaneously force through the tubes 34 a number of globules of
candy stock.
The candy stock forced from the reservoir 23 will be deposited upon a web of
paper unwound from a roll 56. The roll 56 is supported transversely at one end
of the frame by means of brackets 57. The roll 56 is driven by means of a sprocket
chain 58 running over a sprocket wheel 59 connected with the roll and over a
sprocket wheel 60 attached to the shaft of the adjacent roller 10. At the end of
the frame opposite to the roller 56 an extension table 61 is held rigidly in line
with the normal position of the upper run of the belt 12. The inner edge of the
table 61 bears snugly against the adjacent roller 10, as illustrated best in Figure 3.
The web of paper from the roll 56 passes over the belt 12 and over the extension
table 61. The paper is cut in desired sizes by means of two blades 62 and 63.
The blade 63 is carried rigidly by the table 61 and is seated in a transverse slot

page_text: formed in said table. The blade 62 is carried by a back bar 64 that runs above
and parallel with the blade 63 and has its ends respectively sliding in vertical
guides 65. Expansive springs 66 press the bar 64 upward, but the bar 64 and its
attached blade may be periodically drawn down by a treadle 67 operated through
the medium of a rod 68 that runs upward to a horizontal bar 69, the ends of which
are in turn connected by links 70 with the ends of the bar 64. By these means
an attendant standing at the treadle 67 may cut the paper into sheets of any
desired size, so that the paper with the candy stock thereon may be taken away to
paper may,
a convenient place for the drying of the stock, and so that the
desired, serve as a means for holding the candy stock when the same is shipped
for the market.
