has its rear edge pivoted under the table and near its forward edge carries
rollers B resting on the cams, which cams are partly concentric. Set screws 6¹
serve in adjusting the frame B₁ vertically and in thus adjusting the normal height
of the table below the nozzles.

Referring to Fig. 2, each cylinder H and H₁ has entry ports and pistons,
I and I', appropriately attached to the crossheads J and J. The crossheads are
held up by springs so that the entry ports of the cylinders are more or less
uncovered by the pistons to permit the material to pass to the nozzles. The rise
of the pistons may be adjusted by nuts on the piston rods to adjust the degree of
port opening.
The main shaft carries eccentrics L and L' from which links M and M¹ go to
the crossheads. The eccentrics are adjustable in stroke and in time of action, and
set screws at the top of the links serve in adjusting the degree of lost motion and
the relative time of action of the crosshead.
Figs. 9 to 12 inclusive show the construction of the eccentrics. Collars are
fast on the main shaft and carry worins . The body of the eccentric can be
adjusted in eccentricity by the bolts 11, and worms & adjust the advance of the
eccentrics.
As seen in Figs. 13, 14 and 15 the depositing nozzles h and are carried by
plates T and T¹ in a head R, forming the two discharge chambers. The plates
and nozzles may be readily removed from the head R.
As seen in Fig. 13 the nozzles h and are arranged in a circle. If two of
them deposit dough and two of them deposit jam, the deposits will together form a
flat cake of mosaic character. The design and arrangement of the nozzles may be
varied indefinitely. The quantity discharged from the several nozzles may be
adjusted by means of their controlling pistons so that in the mosaic cake thus
formed the quantity of deposit will differ in the various substances. Referring
to Fig. 2, when the crossheads go down the pistons force the material out of the
nozzles and deposit the material on the pan. When the pistons rise they cut off
the flow and suck. back the surplus, thus making clean deposits. The time of
action of the pistons may be adjusted at pleasure and to suit the material and
character of work.
The
In Figs. 16 to 19 inclusive I show the nozzles h' arranged within the nozzles hº.
The two substances will thus be delivered concentrically. In Fig. 16 is shown the
exterior nozzle delivering dough, the piston controlling this nozzle at this time
descending. When this delivery of the dough has been thus far effected then the
piston of the interior nozzle delivers, for instance, jam, as seen in Fig. 17.
piston controlling the inner nozzle now rises, ceasing the delivery of jam and
sucking up the surplus, the exterior nozzle continuing to deliver dough, as seen
in Fig. 18, thus completely enveloping the jam in the dough. The low place in
cams C at this time causes table B to descend, thus cutting off the delivery of
dough, as seen in Fig. 19, and leaving the compound cake completed. The machine
having deposited a row of such cakes in the pan the pan feeds forward and the
table rises ready for the deposit of the next row.
In Figs. 20 to 22 is shown the operation of the concentric nozzles in icing a
cuke, this operation calling for such an adjustment of the crosshead moving devices
as will cause the outer nozzles to make their deposits only after the inner nozzles
have completed their deposits. In Fig. 20 the cake material is being deposited.
In Fig. 21 this deposit is complete and the flow has ceased and the surplus been
sucked back and the deposit of the icing material through the outer nozzle is
taking place. In Fig. 22 the deposit from the outer nozzle has also ceased and the
.table has descended to break the deposit loose.
