PROVISIONAL SPECIFICATION.
An Improved Weighing and Filling Machine.
I, PAUL MORIVAL, of Place du Theatre, Lille, in the Department du Nord,
France, Weighing Machine Manufacturer, do hereby declare the nature of this
invention to be as follows:—
This invention relates to a machine for weighing and filling all kinds of
pulverulent materials and grain into sacks or other receptacles, and, if required,
liquid materials capable of being contained in sacks or bags or other receptacles, of
different length and capacity.
The weighing machine is of the same general construction as the ordinary
apparatus of this kind, that is to say it is provided with a frame or support, a beam
or weighing arm, a weighing platform or table on one side, with a slider, and on the
other side an apparatus for suspending the sacks or bags or other receptacles from
the centre, and an indicating pointer moving over a dial or sector. But in order to
enable sacks or bags or other receptacles of different heights to be weighed, the
apparatus in question comprises a lift which effects this result. This lift is
composed on the one hand of a bar forming a rack and acting as a kind of jack by
means of a crank arranged and operated at the upper part of the frame, and the
head of which supports the beam or weighing arm; and on the other hand of a
special arrangement supporting the steelyard lever, consisting of a bar attached to
the head of the lift, sliding vertically in a guide attached to the frame, and which
is adjusted by a screw stop. The weighing platform on the other hand is adjusted
to the varying heights by means of a ring pierced with lateral openings and carried
by the supporting rod of such platform, and in which the lower part of such rod
(which is pierced with holes corresponding with the lateral openings in the ring)
can slide up and down. The length of said supporting rod of the weighing plat-
form can be adjusted to any height desired by means of a movable key or pin
which can be inserted in the holes and in the lateral openings in the ring.
The slider above referred to serves to give the tare or the weight of the empty
sacks before they are filled.

COMPLETE SPECIFICATION.
An Improved Weighing and Filling Machine.
I, PAUL MORIVAL, of Place du Theatre, Lille, in the Department du Nord,
France, Weighing Machine Manufacturer, 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 :-
This invention relates to a machine for weighing and filling all kinds of
pulverulent material and grain into sacks or other receptacles, and, if required,
liquid materials capable of being contained in sacks or bags or other receptacles, of
different length and capacity.
The accomm
awing
show a suitable form of annaratus embodying my

page_text: Fig. 2 'a plan view of same, and
Fig. 3 a side view of the top part thereof.
The machine is of the same general construction as the ordinary weighing
apparatus known as "beam" machines, and it differs only in the combination by
means of which the beam serving directly to effect the weighing, may be raised or
lowered at will with the guide to any desired height by a lift, so as to place same
at a height to suit that of the sack to be weighed, whilst the supporting rod of the
corresponding
weight platform or plate may be lengthened or shortened to a
extent.
The apparatus is mounted on a frame or support A, B, C, D. In the top part
of the frame the rod b of the lift is mounted and can slide vertically, such lift being
in the form of a rack, similar to a jack for lifting heavy weights. The rack engages
the teeth of a toothed wheel enclosed in the part H of the frame, and mounted on a
horizontal shaft actuated by a hand wheel f. The supporting of the lift is effected
by a pawl q, which engages the teeth of a ratchet wheel r, mounted on the shaft of
the hand wheel f. The head of the lift rod between its two curved arms K
supports the weighing beam E, mounted at its centre on a horizontal bar I provided
at each end with a steel knife edge. These knife edges rest on a piece L of steel
or agate fixed to the two arms K. One of the two arms carries a fixed dial
sector N, and a needle M indicating the degrees is placed in the centre of the
weighing beam E.
The
The beam E terminates at one end in a fork which supports a cylindrical
hopper G, provided with a funnel for the introduction of the material.
hopper G carries two ears to receive the knife edge pivots which rest on two pieces
of agate or steel fixed on the arms of the fork. The lower part of the said hopper
is provided with a ring or flange on which the mouth of the sack is fixed by a
strap p, tightened by a buckle, or other suitable means.
At the opposite end of the beam E the weight platform c is suspended in the
ordinary way. The apparatus is provided with a guide R which can be raised by
the same movement as that which raises the lift, and which has a releasing
handle S to maintain the beam at rest. A slider d is placed on this same end of the
weighing beam with the object of giving the tare of the empty sack.
The guide R is, as above stated, raised by the same movement as that which
raises the lift. For this purpose it is made solid with the latter by means of a
horizontal bar o fixed to the head of such lift. The guide is carried by a rod T
which slides vertically in a guide U mounted on a support V of horse shoe form
fixed to the frame of the machine. This rod T is held in a fixed position by
means of a screw X actuated by a transverse lever.
The weight platform or plate c is also naturally made adjustable to various
heights. For this purpose.the suspension hook of the platform or plate terminates
at its lower end in a socket Z, pierced with lateral openings, and the supporting
rod a of the plate or platform, which enters such socket, is pierced with corre
sponding holes, so that by passing a key.of any kind transversely through these
holes the height of the weight plate or platform c.can, be adjusted as required.
From the above description the operation of the machine will be easily
followed. A sack having been attached to the hopper G supported on the fork of
beam E, as shown in the drawing, the hand wheel f is actuated, the screw X
being at same time loosened. The rod 6 of the lift is then raised or lowered to the
desired extent so that the sack, according to its height, is held at a given distance
from the ground. In raising or lowering this rod b, the beam E. and guide.R are
carried with it. The weight plate or platform c is itself raised or lowered to a
corresponding extent. The equilibrium of the beam is then effected by means of
the slider d. The weight plate or platform chaving been loaded, the sack is filled
with the material to be weighed until the equilibrium is established. The. weight
is verified, the sack detached, and the operation is repeated as often as necessary.
By this machine the weighing is effected rapidly and with ease.

page_text: 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 :-
In a weighing and filling machine
a. The arrangement for raising and lowering the weighing beam and the guide
consisting in the combination of a rack actuated by a hand wheel and mounted on
the frame of the apparatus, and of a rod sliding in a guide attached to such
frame.
b. The means for lengthening and shortening the rod supporting the weight
platform or plate; the whole having for object to enable the weighing and filling
in the same apparatus of sacks of different heights, or of other receptacles of
different heights, such sacks or receptacles serving to contain either pulverulent
materials, grain or seeds, or liquid materials, all substantially as herein described
and shown in the accompanying drawings.
Dated this 27th day of September 1892.
