AN IMPROVEMENT IN DROPPING AND PIPING MACHINES FOR BISCUIT MAKING, BISCUIT PIPING, AND OTHER CONFECTIONERY PURPOSES."
Year: 1880

page_text: LETTERS PATENT to Charles Harvey, Biscuit Manufacturer, of 28, Bracken-
bury Street, Preston, in the County of Lancaster, for an Invention of "AN
IMPROVEMENT IN DROPPING AND PIPING MACHINES FOR BISCUIT MAKING,
BISCUIT PIPING, AND OTHER CONFECTIONERY PURPOSES."
PROVISIONAL SPECIFICATION left by the said Charles Harvey at the Office
of the Commissioners of Patents on the 21st October 1880.
CHARLES HARVEY, Biscuit Manufacturer, of 28, Brackenbury Street, Preston, in
the County of Lancaster. "AN IMPROVEMENT IN DROPPING AND PIPING MACHINES
FOR BISCUIT MAKING, BISCUIT PIPING, AND OTHER CONFECTIONERY PURPOSES."
My improvement chiefly consists in introducing an ejection plate, or any other
ejection appliances, whereby the drops can be made on paper as well as upon the
naked pan, the ejection plato rising and falling with the pan, thereby keeping the
paper close to the pan untill such time as the biscuits have left the dropping tubes;
and when the machine is used for biscuit piping, the ejection plate is for the
purpose of keeping the biscuits close to the pan untill they leave the piping tubes.
The four corners of the frame that carries the ejection plate works in slots bolted
to the inside of the machine frame. These slots are so arranged that the ejection
plate will stop at any given point, while the pan that carries the biscuits will drop
below the ejection plate so as to allow of its being drawn from the elevating table
without being obstructed by the ejection plate. Holes are cut in the ejection
plate to correspond with the shape of the dropping or piping tubes, so that when
the pan is lifted by the elevating table up to the mouth of the tubes the ejection
plate will pass up between the tubes during the time the drop is being made.
Different ejection plates can be used to correspond with the shape of the different
tubes used; for the ejection plate I use zink or any suitable material, the frame
being made of iron or any other suitable material.

the said Charles Harvey in the Great Seal Patent Office on the 19th April
1881.
CHARLES HARVEY, Biscuit Manufacturer, of 28, Brackenbury Street, Preston, in
the County of Lancaster. "AN IMPROVEMENT IN DROPPING AND PIPING MACHINES 5
FOR BISCUIT MAKING, BISCUIT PIPING, AND OTHER CONFECTIONERY PURPOSES."
This Invention relates to machines, already in existence, to be used in the
manufacture of queen's drops, and other similar confectionery. By the construction
of the machines I refer to, you have to fix (by nails or otherwise) a number of
sheets of paper (forming a thick pad) on the top of the elevating table, and make 1
the drops upon the top sheet, then extricate it from the nails, and remove it from
the table.
My improvement consists in introducing an ejection plate (between the table
and the tubes), by which means the drops can be made upon a single sheet of
ordinary or wafer-paper placed upon a pan for the purpose of receiving them, and 1
the pan and single sheet of paper containing the drops removed together from the
table.
For the ejection plate I use brass, zink, or any other suitable material.
Holes are made in the said ejection plate to correspond with the tubes and size
of the drops to be made, so that when it is lifted up by the table the mouth of the 2
tubes will pass through them; and by the means of its four corners working in
guides bolted to the inside of the machine frame it is kept in its proper position,
and rises and falls perpendicularly with the pan and paper, by which means it
keeps the paper close to the pan during the descent of the table, thereby pulling
the drops from the ends of the tubes.
The guides of the ejection plate are open at the bottom, by which means the
plate is put into them, and by four loose pins or thumb screws through the frame
of the machine for the plate to rest upon, it can be stopped at any given point,
the pan and drops descending with the table below the ejection plate, so that they
can be removed without being obstructed by the ejection plate. A piece is cut out
of the front of the ejection plate opposite one of the tubes, so that the drop can be
seen when the table and plate is lifted up.
Four pieces are cut out of the ends of the elevating table to allow it to pass the
ends of the pins or thumb screws that stop the ejection plate.
When the machine is used for biscuit piping, the ejection plate is for the purpose
of keeping the biscuits close to the pan or wire during the descent of the table,
by which means the biscuits and sugar designs are pulled from the ends of the
piping tubes.
My Invention also consists in constructing guides for the biscuits that are to be
piped. These guides are for the purpose of directing each biscuit to the month of
its own piping tube, the centre of which must correspond with the centre of the
tubes. For the said guides I use perforated or identated wood or metal. The
biscuits are placed into the holes or indentations, so that when placed upon the
elevating table each biscuit will be directly opposite its own piping tube. If
the hole guides are used, the guides are placed upon a pan or wire for that purpose,
which guides are removed after the biscuits are piped, and used for other biscuits
that require piping. The holes in the said guides, also the holes in the ejection
plates (which must be a trifle smaller than the guide holes) must correspond with
the size of the biscuits that are to be piped.

page_text: Fig. 2 shows my ejection plate A, A, between the tubes D, D, D, and the elevating
table H, H, also shows the thumb screws E, E, the pan B, B, upon which the single
sheet of paper is placed.
Fig. 3 is a top view of my ejection plate A, A, showing the top ends of the
guides C, C, C, C, a section of the machine frame F, F, also the thumb screws E, E, E, E,
that stop the ejection plate.
Fig. 4, 5, & 6 represents guides for different sized biscuits that are to be piped.
In some of the holes biscuits are shown; also upon some of the biscuits the sugar
designs are represented.
Having now described the nature and object of my said Invention, togother
with the manner in which the same is to be or may be performed or carried into
practical effect, and also having illustrated the same by the Drawings annexed, I
wish it to be understood that I claim as my Invention,―
First. The ejection plate as above described, or any arrangement by which the
drops can be made upon single sheets of loose paper, & pulled from the ends of
the drop tubes, or any means by which the piped biscuits and sugar designs can be
forced from the ends of the piping tubes.
Second. 1 claim for biscuit piping the guides as above described and illustrated
by Drawings 4, 5, & 6, or any arrangement by which the biscuits to be piped can
be directed properly to the ends of the piping tubes.
In witness whereof, I, the said Charles Harvey, have hereunto set my hand
and seal, this 13 day of April, in the year of our Lord One thousand
eight hundred & eighty one.
