COMPLETE DIECIFICATION
An Improved Appliance giving Increased Facility for Sacking and
Weighing Coal, and other Materials.
We, JOHN AUGUST OLSSON, of 26, East Terrace, Low Walker, Pavior, and
JOSEPH SCOTT, of 23, Shields Road, Walker Gate, Coal Merchant, both in Walker
on Tyne, 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:-
Our improved appliance consists in an arrangement of apparatus whereby the
bag or sack to be filed is held vertically in a sufficiently opened state so as to be
easily filled while it is at the same time suspended on the scale or spring balance.
We are thus enabled to economise labour dispensing with the necessity of holding
the sack open while it is being filled, of then removing it to the scales or balance
and there adjusting the weight. All these operations being accomplished simui-
taneously by one operation.
In the drawing hereto attached the same letters indicate the same parts in each
view. Fig. 1 represents a front view and Fig. 2, a side view elevation of our
appliance fitted with spring balance-but a weigh beam might be used instead-
For clearness we call this
A is a fixed frame supporting the whole structure.
frame the fixed frame in all the following description. From the top of this fixed
frame is suspended the spring balance S. In order to obviate the necessity for any
vertical adjustment of the fixed frame A we suspend the spring balance from a
hook formed upon a piece of iron having a slot in it and attached to the fixed
frame itself by a bolt and nut. This piece of iron is marked A, 1. The object
of the slot is to enable us to adjust the position of the point of suspension of the
spring balance in the direction of the letters Y, Z, in such way as that friction
of the guides afterwards described on the fixed frame due to the possibly not
exactly vertical position of the fixed frame shall not affect the accuracy of the
weight ascertained.
To the lower part of the spring balance we attach by a hook a frame the lower
part of which is approximately semi-circular (a large segment, but less than a
semicircle) at its centre, but terminating in straight sides the upper part consists
of iron supports suspending it from the hook, in such way as to be, when truly.
This frame is
suspended, in its semicircular part, horizontal or very nearly so.
that which carries the bag or sack, the semicircular portion embracing half the
opened sack and nearly fitting it; this frame is marked B, and in contradistinction
to the fixed frame we call it the suspended frame throughout the following
description.
'
The suspended frame is prevented from swinging in any direction, beyond
a very small movement, by guides marked D, working in slots A 3, in the fixed
frame which guides may be furnished with rolling bushes or any other convenient
appliance so as to reduce friction. The suspended frame has an attachment, to it,
by hinged joint C1 of another frame which for distinction we call the swinging

page_text: frame The swinging frame consists mainly of a piece of supported angle iron
bent to an approximately similar curve to the semi-circular curve of the suspended
frame and so as when locked in its place to fit into that curve and nearly fill it
in the vertical direction by the lower member of the angle iron, and, to overlap
it by the depth of the top member of the angle iron on its upper surface. This
swinging frame is marked C. If now this swinging frame be drawn away from
the suspended frame and half of the hem at the top of the sack be placed between
the suspended and the swinging frame and slightly above (the curved part of)
the suspended frame and the swinging frame be then pushed into near contact
with the suspended frame, it will be seen that the sack will be secured between
them, so long as their relative position and the relative tightness of grip is
maintained.
We regulate the tightness of grip by means of a locking arrangement, and we
have in addition a means of adjusting the height of the suspended frame relatively
to the swinging frame so as to get adjustable pressure in both directions to bear
upon the bag.
-L
The locking arrangement is operated by a handle working a lever and drawing
a wedge shaped piece of iron through a slot in an attachment to the swinging
frame, and against a recess in the back of the suspended frame. The movement
of this handle in one direction thus increases the pressure on the sack to any
desired degree, and its movement in the opposite direction releases the sack.
We place at the lower end of the suspended frame a light support for the full
sack in a convenient position near the ground so as to give a very slight fall to
the sack when released from the grip of the swinging frame.
We would have it understood that altho we have described and drawn an appara-
tus in detail we do not confine ourselves to the exact details as described & drawn
but only to the essential features substantially as described and illustrated.
In the drawings hereto attached all the parts marked A, with or without
distinguishing numbers are parts of what we have called the fixed frame; all
parts marked B, however separately distinguished, are parts of what we have:
called the suspended, frame, and parts marked C distinguished or not are parts
of what we have called the swinging frame.

required to make it clear.
A is the fixed frame, A1 is the hook carrying the spring balance, A2 is the a
baseplate and platform which may be weighted so as to hold the whole frame A
securely in its vertical position. A 3 gives the position of the slots in which
the guides D of the suspended frame move.
B is the suspended frame, B1 being the suspending bars (which are omitted
in Fig. 2 in order to shew what would not be otherwise seen in this illustration, 4
namely some detail of the swinging frame) and the cross bar ending in the
guides D. This cross bar is shewn by itself in Fig. 3. The lower bar B2, which
is also a cross bar carrying guides, is straight and carries the weight of the full
sack when released as before described.
C is the swinging frame swinging on a hinge C1 and carrying by its suspending 4
bars C2 the angle iron before described C3-carrying also the handle C4 for
gripping and releasing the sack, the fulcrum C5 on which this handle moves the
drag link C6 which is operated by the movement of the handle. This drag link
is so shaped as shewn in the drawing Fig. 2 as that the upward movement of the
part of the handle marked C4 depresses the drag link the bottom of which comes 5
into contact with the back of the cross bar B1 and with the back end of a slot
in C7 and so drags the angle iron C3 into nearness to the front of B1 the sack
being between them.
It remains only to refer to the adjustment of the relative heights of C3 & B 1.
This is effected by the nuts B3.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is: --
The combination of parts consisting of fixed frame, suspended frame and swing-
ing frame with the provisions respectively attached to the same whereby the
purpose of our invention is carried out substantially as described.
