FOR PACKING BAGS, SACKS, TINS, AND OTHER RECEPTACLES FOR FLOUR,
STARCH, MUSTARD, AND OTHER SUBSTANCES." A communication from abroad

"AN
JOHN WHITTIER THROOP, of Aldersgate Street, in the City of London.
IMPROVED MACHINE OR APPARATUS FOR PACKING BAGS, SACKS, TINS, AND OTHER
RECEPTACLES FOR FLOUR, STARCH, MUSTARD, AND OTHER SUBSTANCES." A com-
munication from abroad by H. L. Mattison, of Oswego, in the United States of
America.
The object of this Invention is to provide a machine, which while easily set up,.
occupying little space and requiring very little power, will pack flour, starch, and
all pulverized, fibrous, granulated, and dessicated stuffs into any kind of bag,.
wrapper, or receptacle, whether of cloth, wood, tin, pasteboard, paper, pottery ware,.
foil or other material, and of any shape, round, square, or oblong, not only with
great facility and rapidity but packing every package of an exact and uniform
weight.
This machine or apparatus is composed of a frame, the lower part of which will
be supported on trestles or otherwise, to form a table, and which will carry sus-
pended from its upper part an inverted cone or other shaped. receiver of the
substance to be packed, the top of the frame also serving to support gearing for
driving a screw or other suitable apparatus placed within the cone, for the purpose
of forcing the substance to be packed out of the cone into the wrapper or package.
which is to receive it, the lower end of the cone being provided with a conduit or
shoot of the shape of the package to be filled. The empty bag, wrapper, or package,
when placed beneath the cone is carried by a moveable platform or holder pressed
upward by weights beneath the table, these weights being regulated by the weight
of package required.

page_text: As the bag, wrapper, or receptacle fills the weight pressing it upward is gradually
overcome by the counter pressure of the filling bag until there is perfect equipoise ;
the package uniformly packed from bottom to top is then removed, another sub-
stituted, and so on.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Whittier Throop in the Great Seal Patent Office on the 9th
May 1877.

AN
JOHN WHITTIER THROOP, of Aldersgate Street, in the City of London.
IMPROVED MACHINE OR APPARATUS FOR PACKING BAGS, SACKS, TINS, AND OTHER
RECEPTACLES FOR FLOUR, STARCH, MUSTARD, AND OTHER SUBSTANCES." A com-
munication from abroad by H. L. Mattison, of Oswego, in the United States of
America.
The object of this Invention is to provide a machine which, while easily set up,
occupying little space and requiring very little power, will pack flour, starch, and
all pulverized, fibrous, granulated, and dessicated stuffs into any kind of bag,
wrapper, or receptacle, whether of cloth, wood, tin, pasteboard, paper, pottery ware,
foil or other material, and of any shape, round, square, or oblong, not only with
great facility and rapidity but packing every package of an exact and uniform
weight.
This improved packer is composed of a frame carrying suspended from its upper
part an inverted cone or other shaped receiver of the substance to be packed, which
may be fed into it by a hopper or otherwise,, the top of the frame also serving to
support gearing for driving a screw or other suitable apparatus placed within the
cone for the purpose of forcing the substance to be packed out of the cone into the
wrapper or package which is to receive it; the lower end of the cone is provided
with a conduit or shoot of the shape of the package to be filled, and the empty bag,
wrapper, or package, when placed beneath the cone is carried by a moveable
platform or holder pressed upward by weights.
As the bag, wrapper, or receptacle fills the weight pressing it upward is gradually
overcome by the counter pressure of the filling bag until there is perfect equipoise;
the package uniformly packed from bottom to top is then removed, another sub-
stituted, and so on.
On the accompanying Sheet of Drawing Figure 1 represents an elevation or
front view of a packer suitable for filling small packages; Figure 2 is a similar
view, but illustrates a modification of the above, the arrangement shown being
adapted for filling sacks, barrels, or other receptacles. I have shown this packer
occupying the space between the two floors of a mill or warehouse, the hopper
being in the upper chamber, but it will be evident that I may place it in any
suitable position.
Similar letters of reference are placed upon and denote similar parts in each of
the Figures respectively.
A is the cone; a, hopper feeding same; B, cylinder or outlet from cone; it may
be stationary or moveable and the shape of the outlet made to correspond with that
of the receptacle to be filled; C, screw forcing the substance to be packed out
of A and B; D, wheels driving screw C; E (Figure 1), table; F, moveable
platform or cage carrying the bag, sack, or receptacle to be filled; G, cords or chains
for raising platform F; H, compensating pulley or cam; I, counterweights;
K, steelyard; L, break gear; M, starting gear; N, case, sack, or other receptacle.
The action is as follows:-Having placed the case N upon the platform F,
Figure 1, or strapped the sack N, Figure 2, upon the cylinder B, the platform F
is at once raised by means of the counterweights I aud cords G close to the under
side of the cylinder or outlet B, and the screw C is set in motion by the wheels D
driven by any available power. By the rotation thus given by the screw C the

page_text: flour or other substance in the case A and cylinder or outlet B is pressed out into
the case or sack N upon the platform F.
In order to ensure a uniform packing the pressure of the counterweights I is so
arranged, by means of the compensating pulley or cam H, as to allow the platform F
to descend as the case or sack N becomes filled, and directly the proper quantity
of meal or other substance has entered the bag or sack N the steelyard K is raised
and the screw C at the same time thrown out of gear by suitable connecting rods
or otherwise.
It will be seen, both in the packer for small packages, shown Figure 1, and in
that for sacks or larger packages, Figure 2, that the platform F may be very
carefully counterbalanced, and that the flour or other substance is therefore without
further trouble packed uniformly from the bottom to the top of every bag, sack, or
other receptacle.
The framing of the machine will be of such form and material as may be best
suited for the dimensions and intended use of the packer, and whether it is to be
a fixed or a portable machine.
Having now described and ascertained the nature of the said Invention, com-
municated to me as aforesaid, I would have it understood, that I do not confine
myself to the precise mechanical details above set forth and illustrated on the
Drawing, as other well-known mechanical devices might be used for operating
parts of this improved packer while retaining the essential features of this Invention,
nor do I limit myself to any exact dimensions of parts, and that what I claim as
secured to me by the herein-before in part recited Letters Patent is, the use of a
machine or apparatus for packing flour and other substances into bags, sacks, and
other receptacles, such machine or apparatus being composed of a cylinder or other
shaped receiver within which is operated a screw or other conveyer in combination
with a moveable counterbalanced platform and weighing apparatus, all constructed
and arranged to operate substantially as and for the purpose above set forth.
In witness whereof, I, the said John Whittier Throop, have hereunto set my
hand and seal, this Seventh day of May, in the year of our Lord One
thousand eight hundred and seventy-seven.
