RECEPTACLES."
PROVISIONAL SPECIFICATION left by the said Alexander Scott and Joseph
Duncan Scott at the Office of the Commissioners of Patents on the 14th
February 1881.
ALEXANDER SCOTT, the younger, and JOSEPHI DUNCAN SCOTT, both of Greenock,
in the County of Renfrew, North Britain. "IMPROVED APPARATUS FOR AIDING
THE FILLING OR PACKING OF SUGAR OR OTHER GRANULAR OR POWDERED
MATERIALS IN CASKS OR OTHER RECEPTACLES."
This Invention relates to improved apparatus for facilitating and rendering more
thorough the filling of sugar or other granular or powdered materials into casks or
other receptacles by subjecting the casks or other receptacles while being filled to
shaking, brought about by a series of falls or downward motions, consisting of
vertical falls combined with or succeeded by one or more side tilts or angular
falls.
Under one modification of apparatus constructed according to this Invention,
there is an upper plate or table for carrying the cask or receptacle in which the sub-
stance is to be packed, the said table having on its underside four or other suitable
number of rollers, and by means of a corresponding number of levers bearing upon
the rollers the table is raised, and when the levers are drawn from beneath the
rollers it falls vertically. The levers are connected by links and caused to oscillate
upon horizontal axes mounted on suitable bearings, and the levers are moved back-
wards and forwards, or vibrated by any suitable driving mechanism. On the driving
link or connecting rod there is a wedge shape piece, which at each backward
movement of the said link bears upon a projection from the underside of the upper
plate or table, and causes the said upper plate to be raised at an angle and
thereafter to fall suddenly. By means of the arrangement of this machine the
upper plate or table is raised and allowed to fall vertically twice for every time it
is tilted or moved angularly.

page_text: In order to produce, besides the vertical falls and one tilt on one side, an additional
tilt on the opposite side, the apparatus may consist of the arrangement just described
with a second wedge shape piece fixed on the connecting rod, and a double arm
lever attached to the horizontal axis of the one set of levers. When the additional
wedge shape piece bears upon the one end of the double arın lever, the other end is
made to rise and press against a projection from the underside of the table, and
when the wedge shape piece on the connecting rod travels clear of the short end
the lever is allowed to drop, so as to permit the upper plate to fall angularly.
Or the form of apparatus just described may be modified in another way so as
to produce the same motions. The connecting rod or driving link is made to
extend through the side of the bed box, and a wedge shape piece is fixed to the
said end of the rod. This additional wedge shape piece acts in the same way as the
one on the other end, namely, by bearing on a projection from the underside of
the upper plate, so as to cause it to rise and fall angularly.
Another modification of apparatus according to this Invention is like the pre-
ceding, also arranged to give the same series of motions. In this case the upper
plate or table has on its underside four or other suitable number of rollers, and
underneath is a carriage or frame set in a bed box and worked backwards and
forwards by a connecting rod having on it two wedge shape pieces, one at each end,
to give the tilting movements. The carriage or frame has four rollers placed under-
neath it and four rollers placed above it to act upon the rollers on the underside of
the table or plate and give the vertical movements. By means of the back and
forward motion of the carriage the upper plate receives one vertical fall for each
tilt it receives at the one side, and another vertical fall for every tilt it receives on
the opposite side.
Another modification of apparatus for producing such motions consists as
follows:-
The upper plate or table has on its underside three or other suitable number of
rollers, pulleys, or rounded projections, and underneath the said plate or table is a
bed-box having a boss cast or fixed on the centre of the bottom of it to receive
either a worm, spur, or bevel wheel rotating in a horizontal plane. On the back or
the top of the wheel there are four or other suitable number of rounded projections,
V shape moveable wedges, or rollers mounted in bearings. In this Provisional
Specification it is, for the sake of simplicity, assumed that rollers are employed.
For example, three rollers on the wheel are so arranged that three of the rollers on
the upper plate will be on them at once, and at the same time raise the upper plate
vertically; and when by the notions of the wheel the three under rollers are
carried away from beneath the upper ones the upper plate with fall suddenly
vertically. Immediately following the action the fourth roller passes under one of
the upper rollers, and gives to the upper plate an angular tilt, and in this way
there will be maintained a succession of vertical falls and angular tilts, the latter
being given to the upper plate as the fourth under roller passes each of the rollers
on the underside of the upper plate. The rollers, pulleys, or rounded projections
may be used in any suitable number, either on the under side of the upper plate, or
on the back of the wheel, provided they are arranged in sets so as to give the
vertical falls, and leave an odd roller, pulley, or rounded projection either on the
upper plate or on the back of the wheel to cause the angular falls. The upper
plate or table in each of these machines has parts or pieces projecting from it, or is
connected by one, two, or more links to the upper part of the bed box, so as to
retain the said upper plate in position and still allow it to raise and fall. The
upper plate or table in each case may have a rim.
In order to give a sudden fall to the upper plate or table, the axles of the rollers
or moveable blocks are mounted in oblong holes or slotted bearings, so as to allow
them to slip back and clear themselves from the rounded projections on the under-
side of the upper plate, immediately after the upper plate has attained its
greatest elevation, and thereby allow it to full suddenly.

THE FILLING OR PACKING OF SUGAR OR OTHER GRANULAR OR POWDERED
MATERIALS IN CASKS OR OTHER RECEPTACLES."
Our said Invention relates to improved apparatus for facilitating and rendering
more thorough the filling of sugar or other granular or powdered materials into
casks or other receptacles, by subjecting the casks or other receptacles while being
filled to a compound shaking action brought about by a series of vertical upward
and downward motions, combined with or succeeded by one or more side tilts or
angular falls.
And in order that our said Invention may be properly understood, we now proceed
more particularly to set forth certain arrangements of the system, mode, or manner
in or under which the same is or may be used or practically carried into effect,
reference being had to the accompanying Drawings and to the letters and figures
marked thereon, that is to say :-
Figure 1 represents in vertical section an apparatus constructed according to one
modification of our Invention; Figure 2 is a plan of the same with the table
removed, sbewing the mechanism by which the combined shaking action as aforesaid
is transmitted to the said table. The upper plate or table A (formed or not with a
rim) carries the cask or receptacle in which the substance is to be packed. The
said table has turning in lugs on its underside a number of rollers a, and in its
position of rest it is supported by the ring of wood or like material b carried by the
bed-box B containing the mechanism for transmitting the shaking motion to the
cask or other receptacle in the manner aforesaid. Links 63 connect the table A to
the said box B, as shewn in Figures 1 and 2, so as to retain the said table in
position, but still allow it to rise and fall. In the box B are bearings b² supporting
axes c upon which are levers c² corresponding in number to the rollers a, one
roller a being situated above and in the path of each of the levers c² which have a
bevelled upper part, or are furnished with antifriction rollers at their upper part.
Links connect these levers c². A driving link or connecting rod à extends
through a slot in one side of the box B and is attached at one end to the pin c¹
(carried by the upper parts of two of the levers c) and at its other end to a crank
pin e on the worm wheel E, the said pin engaging in a slot d in the said rod d. A
worm gives a motion of rotation to the wheel E. On the rod d is a wedge shaped
When this

machine is in action the cask or other receptacle is placed on the table A, and the
sugar or other material to be packed is placed therein. On the wheel E being
rotated by the worm f(which may be driven by any convenient motor) the rod a
is moved to and fro and an oscillating motion is imparted to the levers c² which
are thus alternately brought under and away from the rollers a, thereby alternately
raising the table A and allowing it to fall vertically. As the pin e travels in one
direction from end to end of the slot d the bar d is lifted, and the wedge shaped
piece dat each alternate or backward stroke of the link or rod d bears upon the
projection a and causes the table A to be raised at an angle; and thereafter when
the said wedge shaped piece is drawn from beneath the said projection the said
table A is allowed to fall suddenly. Thus it will be seen that by the arrangement
of this machine the table A is raised and allowed to fall vertically twice for every
time it is tilted or moved angularly.

page_text: .
Figures 3 and represent vertical sections of a machine in two different positions
constructed according to another modification of our Invention for producing besides
the vertical falls and one tilt on one side an additional tilt on the opposite side,
that is to say, a tilting action as the pin e lifts and depresses the lever d by
travelling in the slot d³ in each direction. Figure 5 is a plan of the under
mechanism and containing box. As the machine constructed according to this
modification is in some parts like that described with respect to Figures 1 and 2,
and as such corresponding parts are marked with like letters of reference, these
parts will require no further description. On the underside of the connecting rod d
is a second wedge shaped piece and a double arm lever G is capable of turning
on one of the axes c. When the additional wedge shaped piece d' bears upon one
end g of the double arm lever G at each alternate stroke of the rod d, the other
end of the said lever G is made to rise and press against a projection a³ from the
underside of the table A and raise one end of the said table, as shewn in Figure 3,
and when the said wedge shape piece d travels clear of the said end g of the
lever G, the other end g by reason of its greater weight falls (into the position,
Figure 4), and the table A falls angularly. The projections d³ and dwill of
course act to give the angular falls alternately at opposite sides of the table A
between the vertical falls given by the levers . In these Figures 3, 4, and 5
we have shewn the wheel E as a spur wheel driven by the pinion f, but we wish
it to be understood that in none of the arrangements herein described do we
limit ourselves to any particular means for giving the reciprocating motion to the
rod d.
Figure 6 represents a vertical section, and Figure 7 a plan of the under
mechanism of a modified form of the arrangement hereinbefore described for
producing the same motions. The rod d is made to extend through slots in the
opposite sides of the box B, and the wedge shaped piece d₁ is formed or fixed at
the end of the said rod, and acts upon the projection a³ from the underside of the
table A, so as to cause the said table A to rise and fall angularly, essentially as
herein before described with regard to the wedge shaped piece d' and projection a³,
Figures 3, 4, and 5. In this modification, Figures 6 and 7, the rod & is shewn as
attached to the pin et carried by the links c³, and the crank pin e is shewn mounted
upon a separate crank disc E, but we wish it to be understood, that in neither of
the arrangements herein described do we limit ourselves to the particular methods
of attachment of the rod d to the levers c² shewn in the Drawings, as they may be
connected in any suitable way, which will give the necessary oscillating movement
to the said levers c². The other parts in the modification, Figures 6 and 7, are
similar to those Figures 1 and 2, and are marked with the same letters of
reference.
Figure 8 represents a vertical section, and Figure 9 a plan of the under
mechanism of a modification of the preceding arrangement for giving the same
series of motions. In this modification, in place of the levers ca carriage or
frame His employed set in the box B, and worked backwards and forwards by the
rod a connected to the said carriage by the pin h, the said rod d having on it the
two wedge shaped pieces ³ and d to give the tilting movements, as before
described, by acting on the projections a³ and a from the underside of the table A.
The carriage or frame H runs upon wheels ², and carries the roller ³ for acting
upon the rollers a which are in their path of travel, and giving the vertical
movements to the table A. When therefore the carriage H is moved to and fro by
the rod d, the table A receives one vertical fall for each tilt it receives, at the one
side and another vertical fall for each tilt it receives at the other side. The other
parts which correspond with similar parts in the preceding Figures are marked
with the same letters of reference, the links bs being omitted from Figure 9 for the
sake of clearness.
In the herein before described arrangements it is to be understood that we do not
limit ourselves to four rollers a and four actuating levers or wheels h³, but we
have found this a convenient number.

page_text: Figure 10 represents in vertical section, and Figure 11 in plan with the table A
removed, another arrangement constructed according to our Invention for producing
the said motions. The table A has on its underside six rounded or inclined.
projections. The bed-box B contains a surface of wood or similar material b for
the table A to bear against, and has a boss & cast or fixed at the centre of its
lower part, upon which the bevel wheel is caused to revolve by the pinion m
engaging therewith. The wheel carries on its upper face four rollers and
mounted in slotted holes 1 in bearings .
The rollers and are so arranged that as the wheel is rotated the three
rollers marked on the said wheel will bear at the same time upon the inclined
surfaces of three of the projections i on the table A, as shewn in Figure 11, where
the said projections i from the table are indicated by dotted lines, and raise the
said table A vertically, and when by the revolution of the wheel the said
rollers are carried from beneath the said projections i, the table A will fall
vertically suddenly. Immediately following this action, the roller 18 passes under
one of the projections and gives to the table A. an angular tilt, and it will be
readily understood that in this way there will be maintained, during the revolution
of the wheel, a succession of vertical lifts, falls, and angular tilts of the table A,
the angular tilts being given to the said table A, as the roller 13 passes each of the
projections on the underside of the said table A. The rollers 12, 13, and
projections may be in other numbers than those shewn, provided that the rollers
on the wheel be arranged beneath the projections on the table A, so that the said
table is raised vertically to give the vertical falls, and provided that there be an
odd roller (which may be either on the wheel, as shewn, or on the table) to give the
angular lift and falls to the said table in between the vertical lifts, essentially as
hereinbefore described.
It is to be understood that a worm or spur wheel, or other means of giving
revolution to the carrier of the rollers and may be used in place of the bevel
wheel shewn; and that in place of the said rollers and 13, bevelled projections
may be employed, and that rollers may be used in place of the inclined projections i
upon the table A. Links, like those marked b³ in the preceding Figures, may be
used to retain the table A in position.
The oblong holes 15, in which the axes of the rollers 12, 13, are carried, allow the
said rollers to slip backwards and clear themselves from the rounded projections i
on the underside of the table A, immediately after the said table A has attained
its greatest elevation, and thereby allow. the said table A to fall suddenly, which
greatly facilitates the packing operation. Where inclined projections are used in
place of rollers 12, 13, these may also be caused to slide in similar slots for the like
purpose.
In the various forms of apparatus herein before described, the table A and bed
box B may be of circular, square, or any other desired figure.
Having now described and particularly ascertained the nature of our said
Invention, and the system, mode, or manner in or under which the same is or may
be used or practically carried into effect, we would observe in conclusion that we
do not claim generally the imparting of a simple jolting motion to casks or other
receptacles for packing purposes, as we are aware that it has hitherto been proposed
to give such a simple jolting motion to receptacles for the said purposes, but what
we consider to be novel and original, and therefore claim as the Invention secured to
us by the hereinbefore in part recited Letters Patent is,-
First. The improved apparatus for aiding the filling or packing of sugar or other
granular or powdered materials into casks or other receptacles, whereby the said
receptacles and their contents are submitted to a series of vertical lifts and falls,
combined with a series of side tilts or angular lifts and falls, essentially as
herein before described.

to a series of vertical lifts and falls, alternately with angular or tilting lifts and
falls.
Eighth. The mounting of the rollers or projections in slotted holes or bearings
