Apparatus for Packing Cans into Boxes.
GUILLERMO ANTONIO FARINI 10 Henrietta Street Covent Garden W.C.
Impresario and Author, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention consists of a machine for packing cans into boxes by rolling them
into shelves, the first shelf filling, causes the cans to run into the next one and so
on, until there are as many full shelves as there are rows in the boxes. The sides
of these shelves are open to the width of four cans or as many as the box holds in
length at the back of the open shelves. I employ a frame to which is attached a
lever, and by raising this lever the frame enters the shelves and pushes the cans
resting on them forward, the cans on the top shelves then drop down on to the
bottom row, and are pushed into a box that lays on its side ready to secure them.
The frame that supports the shelves projects beyond them, a space equal to the
length of a can, so that the cans have this space in which to slide off the shelves,
and pile on top of one another in a solid mass, the exact size of the inside of the
box before reaching it, these projections are an extension of the bottom, and the
sides, but could be made separate, and not only hold the cans in position, but also
act as guides since the ends enter the box when it is placed in position as shown by
the dotted lines H Figure 1.
This is the chief and most important part of the invention. The next principal
part is the feeder or stop that keeps the cans from entering the open shelves or
place from which the cans are pushed, until they are required, and when opened to
let the cans enter they hold the remaining cans back until those set free are pushed
into the box, the closing releases sufficient to fill the open shelves again, and in
this way all injury to the freshly pasted labels is avoided, for if the cans
were pushed past one another the edges of said cans would damage or destroy
the label.
Fig. 1 is a general view of the machine shewing the outside of three tracks with
three apertures to secure the cans, marked 1. 2. 3 and the feeding device shown
on the side, the open end showing one shelf, the sliding frame at the back attached
to a lever, G the guiding frame reaching from the shelves into the box, shown by
dotted lines the box being in filling position.
Fig. 2 is a sectional view on the lines cut through X to X showing shelves or
tracks and frame to push the cans into the boxes.
Figure 3 is a guiding frame to hold cans in position to be pushed into the
boxes.
Fig. 1 A shows the lines of shelves to carry the cans, and 1, 2, 3, are the
apertures down which the cans roll, until each are full.
This frame should contain as many as would fill a box. When sufficient cans to
fill a box have run into the shelves, (usually the number is 24,) the shelves being
three high and containing four in each shelf. The lever C is raised which pushes
the frame D against the cans drawing them forward into the spaces, S between a,
and the box or case H, which is kept in its place by the piece J. The farther
movement of the lever C pushes the cans half way into the box, the lever C is then
depressed withdrawing the frame D and then twelve other cans run into the shelves,
by pushing the arm R which withdraws the pin L, which are again by another

page_text: movement of C, pushed half way into the box, driving the previous twelve cans to
the bottom of the box. In this way the freshly labelled cans never get injured as
the cans are constantly on there ends which overlap.
At the back of the shelves is the lever C with slot N, which permits it to form
the circle as it pushes in the frame D. E is a guide to the said sliding frame D,
which prevents it from moving laterally when it is pushed in or withdrawn. M is
the frame of the stop or feeder, L L L are three points on either end of the
frame M, which pass through the sides of the tracks and enter between the cans in
the space formed by the contact of the circular ends thereof. O is a centre piece
which is attached to the side of the shelves and on which the frame M is hingel.
P is a spring that forces the front points home when the handle R is released,
but as an alternative, they could be opened and shut by the lever being attacbed to
them or coming in with them.
Fig. 2 is a cross section cut through at dotted lines from X to X. A. A. A. are
the shelves. D. D. D are the ends of frame that push the cans from the shelves
into the guiding frame S.
Fig. 3 S S S is the frame which is male to fit the interior of the box, and it
receives the cans when pushed from the shelves, and holds them one on top of one
another, and guides them when pushed into the box. So is a detachment sliding
frame that fits the guiding frame S' S³ S, and is pushed into the box with the cans
on it. The box is turned over to have the lil nailed, and the sliding frame So is
withdrawn and put back into the place. This is used when the cans are very
heavy and the labels are thin, and obviates the sliding of the cans on S or bottom
or sides of the box, since they are carried bodily into said box on the sliding
frame So.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. In a box filling machine for cans an holder, having an open front, and
a feeding opening, and feed chute to put the cans into.
Second. In a box filling machine for cans, a holder into which the cans are
piled, in shape to conform to the box adapted to carry the cans into the box and
to be withdrawn without withdrawing the cans.
Third. In a machine for filling cans into boxes the combination of a carrier
into which the cans are fed, and means for moving the filled carrier into the box.
Fourth. In a machine for filling cans into boxes the combination of a carrier
into which the cans are fed, means for forcing the filled carrier into the box, the
carrier being adapted to be withdrawn without withdrawing the cans.
Fifth. In a machine for filling cans into boxes the combination of a carrier into
which the cans are fed and piled, means for moving the carrier to permit the
piling of the cans in adjoining rows and for moving the carrier into the box.
Sixth. In a machine for filling boxes, a holder adapted to hold a group of cans,
in the relation in which they are held by the box, and means for moving the cans
into the box.
