"IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS FOR MOULDING PLASTIC
SUBSTANCES FOR CONFECTIONERY AND OTHER PURPOSES."
This Invention consists in improvements in the construction of apparatus
especially applicable for forming the raised sugar ornaments of cakes and for other
similar purposes, and by means of which apparatus such operation is effected in a
more cleanly and rapid manner than is the case with apparatus usually employed
for the same purpose, whilst at the same time the figures are not only more
perfectly formed, but vari-colored figures with great symmetry of color can be made
with equal ease as plain figures. The said apparatus is also suitable for making
cornices and other articles from plaster of Paris, and other plastic materials.
The said apparatus consists of a cylindrical or other conveniently shaped receiver
constructed of brass, silver, or any suitable material. One end of the said receiver
is open and is closed by a cover which is secured thereon by means of a pin and
right angle slot, or any other suitable and known contrivance. The opposite end
of the receiver, which is closed, has formed therein one or more apertures, which, when
desired, can be furnished with nozzles or nipples. Within the receiver, and fitting
the interior thereof, is a piston or plunger, to the centre of which is connected a rod
in such a manner as to admit of being turned independently of the same, and the said
rod, which passes through an aperture in the before mentioned cover, is provided
with one or more cross bars or pins, a slot being made through the cover for the
passage of the same. A spiral or other suitable spring is arranged in the interior
of the receiver, the ends thereof bearing respectively against the piston and cover.
A cut off contrivance of any suitable nature, for instance, a disc, is arranged near
the apertures or nozzles in such a manner that by the actuation of a cam pivoted
eccentrically to the receiver, the flow of plastic material can be intercepted until
the said can is moved back to its former position.
The action of the apparatus is as follows:-The piston rod is drawn out until the
spring is fully compressed between the piston and cover, the said rod is then turned

page_text: partially round, thus bringing the cross bars or pins into such a position that they
cannot pass through the slot in the cover, the bar or pin nearest the piston bearing
against the cover and thus securing the whole together, after which, the cover,
having been disconnected, is, together with the piston, spring, and rod, withdrawn
from the receiver; the plain or vari-colored plastic substance is then placed within
the receiver either in layers or in any other desired manner, but in all cases a space
is left for the reception of the piston and spring, which are then replaced and the
cover again secured. When it is desired to actuate the apparatus, the piston rod
is turned until the cross bars or pins are brought into coincidence with the slot in
the cover, thereby releasing the spring, which bearing against the piston forces the
same along the receiver and thus causes the plastic substance to be pressed through
the aperture or apertures provided for the purpose of moulding the same, the said
moulded substance as it is expressed may be received on a travelling band or
deposited in any suitable way. When more than one cross bar or pin are employed,
the action of the spring can be arrested by turning the piston rod, as herein before
described, at any point of its operation.
It will be readily understood from the above description that the said apparatus
may be made sufficiently small to hold in the hand or that it may be made larger,
in which case it will be mounted in a suitable frame.
