mold structure is adapted to rest or be moved by
70 sliding along the ?oor, table or 'other'support
The runners 21 are rigidly connected transversely
-of the mold structure '|‘l by means of suitable
brace rods 26. A metal band or bumper guard
23 is mounted around the lower ends of the molds
24, being securely‘ welded to each of the molds 24,
different combinations of ?avors may be used, or .
that the various parts of the serving 66 may be
formed of other materials in other combinations, 65
such as forming the portion 62 of ice cream, the
portion 63 of frozen custard and covering the
core with a layer of water-ice in place of the ice
cream 66 without departing from the spirit‘of
my invention.
In the manufacture of the serving 63, the
apparatus shown and described in connection
with Figs. 1 to 16 of the drawings is used in the
following manner: The molds 24 of the mold
structure II are partially filled with chocolate
"ice cream 82 by placing .the' ?lling apparatus
centrally positioning each peg 38 and its core 12
shown in Fig. l in the molds shown in Fig. 2, as
over the molds 41. When the cores 12‘ are so
illustrated in Fig. 3, and a quantity of chocolate , lowered into the molds 41, they are submerged
ice cream 32 is placed in the ?lling pan H). The
ice cream 82, when it is placed in the ?lling pan
ill, is soft and semi-plastic or ?uid, capable of~
?owing, and‘runs down into the ?lling tubes l6.
After the tubes it are ?lled level with the top .of
the pan it, a squeegee 58 is manually operated,
10 as shown'in Fig.3, to force the ice cream 62 into
any un?lled tubes andv to remove the excess
cream that may have been deposited therein.
The amount of ice cream deposited in the molds
24 depends upon the volume of the ?lling tubes
i6, and may be varied by increasing or'decreasing
the-size of the tubes l6 as desired.
When the ?lling apparatus is removed from
the mold structure H, the ice cream or other
material in the filling tubes it, being capable of
?owing, will run out the bottom and ?ll the lower
portion of the molds 24, as shown best in Fig. 4.
The un?lled portions of the molds 24 are then
completely ?lled by pouring another kin or
?avor of ice creamor other material, such as
25 fruit ice cream 63 having. particles of chopped
fruit M therein, into the mold pan iii of the mold
structure i'i. This second kind or ?avor of ice
in the semi-?uid or liquid material 65 in the
lower part- thereof and thereby displace and
force the liquid 65 up and entirely around the
core 12 until the entire mold 41 is ?lled with
material. By means of the squeegee 58, having
slots 6| therein adapted to‘ engage and ride on '
the top of the bars 32, as best shown in Figs. 10 10
and 11, the displaced material'is. smoothed out
to form the bottom of the serving and the excess
material may be removed from the mold struc
,The mold structure 4| is next placed in a re
irigera'ting" brine tank (not shown’), which is
similar in every respect to the brine tank shown
in Fig. 7, until the contents thereof are solidly
frozen and congealed into a unitary mass or
serving. 7 Upon removal of the mold structure 20
ill from the brine tank, it is momentarily placed
in a defrosting tank 8|, containing hot water 82,
which‘ is heated by means of gas ?ames 83.,as
shown in Fig. 12. As soon as the bond is broken
between the servings 68 and the insides of. the 25
molds 41, the former may be removed from the
mold structure ti by lifting up on the peg struc
ture 9|, the servings 89 still being bonded to the

condition, substantially in the condition in which 1 pegs 36 thereof. While the confections or serv

are such thatthey will not tend to intermix. The
excess of the substance 63 is removed from the
mold pan it and/or forced into any un?lled
35 molds it by manipulation of the squeegee 58, as
shown in Fig. 5.
paper bags t4 may be slipped over them. By
this time the metal of the peg structure at has
picked up enough heat from the room to weaken
the bond between the pegs 95 and the servings
til so that the latter may be easily removed
manually from the peg structure.
" Referring to Figs. 17 to 21 of the drawings,
When the molds M of the mold structure ill
have been completely ?lled, the peg structure M wherein I have shown a modi?ed form of peg
