JOHN JOYCE, of Mile End Road in the County of Middlesex, Mechanical En-
gineer "AN IMPROVED MACHINE FOR PACKING, MOULDING, AND COMPRESSING
FLOUR, TOBACCO, TEA, AND OTHER SUBSTANCES INTO PACKETS OR PARCELS "
This Invention consists in the construction of an unproved machine for packing,
moulding, and compressing flour, toa, tobacco, and othei substances into packets or
parcels of any desired weight and size with gicat facility and rapidity
The main body of the machine consists of a fiame, on the upper part of which is
placed a bed plate of any desired shape and size Beneath the bed plate and
within the frame of the machine are fixed two or more brackets or bearings in
which a main horizontal shaft is mounted so as to rotate fieely therein, and by
which the mechanism employed 15 actuated, and for which purpose two main cams
and also a spur wheel are keyed or other wise secured to the said shaft
Upon the
upper side of the bed plate are fixed two vertical columns or pillars which act as
guides to a horizontal cross head, the latter being provided with suitable collais or
cylindrical attachments which enable it to work upwards and downwards upon the
said columns or pillars A rammer or piston is attached to the cross head and
capable of being raised on depressed therewith, and also two vertical iods of any
required length, the lower ends of the same being provided with rollers which
respectively work in the sides of the cams so as to give the requisite raising and
lowering action to the rammer or piston. Upon the upper face of the bed plate
are mounted three or more rollers on which is placed a circular feed ring capable of
evolving on the rollers The said cucular feed ring carries any desired nuniber of
moulds which are fitted into recesses in the said ring and bolted theicto. The ring
is caused to revolve by means of a rack and pinion which are carried on the under-
Bide of the bed plate, and by which a shaft running vertically with the ring and
bed plate. The said vertical shaft is provided with a horizontal lever and pawl
which are so arranged as to pull the feed ring round any desued portion of a revo
lution to one revolution of the main shaft, and which movement brings one of the
moulds under the centre of the cross head to receive pressure from the rammer or
piston, the rammer or piston having been caused to descend and to compress the
Substance in the mould, and having been withdrawn by the action of the before-
mentioned mechanism, the feed ing by the lever and pawl in two movements which

which is actuated by the mechanism below the bed plate as hereinafter mentioned
then passes through the said hole or aperture and foices out the finished packet o
parcel, which during its passage from the rammer or piston has been folded over by
an attendant The said last-mentioned rod is driven by a stud on the edge of
the before-mentioned spur wheel or by a separate cam which is attached to the
main shaft
For the working of the machine a sufficient number of funnels of the proper
size and shape are provided, round which an attendant folds the wrappers, and then
places them in the moulds The attendant weighs or measures the substance to be
packed, moulded, and compressed, and places it in the funnels which are inserted in
the interior of the moulds When the substance has received pressure from the
rammer on piston the funnels are consecutively lifted out of the moulds by two
vertical rods having T shaped ends, and which work through the bed plate and are
raised by a stud on the spur wheel, or by a separate cam attached to the main
shaft Upon the funnels being lifted clear of the top of the mould they are caught by
a forked horizontal lever which is carried by a vertical shaft worked by a rack and
pinion on the under side of the bed plate, and are swung round to the position
necessary for again folding the wrapper
The racks for diving the feed-11ng
shaft and funnel shaft receive their motion from the stud cams on the main
shaft.
A lever and interlocking arrangement are attached to the cross head for the
purpose of obtaining a longer stroke from the main cams when required for large
packets or parcels; the 1ammer or piston is adjusted to the requisite length of
stroke by a screw which is cut along its length, and which is fitted with a nut to
abut against the tube in the cross head through which the ammer or piston
works.
For the purpose of driving the machine, steam, manual, or any other suitable
motive power may be employed.
