COMPLETE SPECIFICATION.
New or Improved Apparatus for Facilitating the Filling, Weighing,
and Loading of Sacks of Grain, Coal, or other analogous
substances.
I, OWEN MCCLUSKEY, of 10, Sir John Rogerson's Quay, Dublin, Ireland,
Superintendent, 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 has reference to new or improved apparatus for (1) facilitating
the filling, (2) the weighing, and (3) the loading of sacks of grain, coal, or other
analogous substance, in a manner whereby considerable economy is effected, and
a more convenient method of performing the said work afforded.
In carrying out my invention I first construct a suitable frame consisting of
four uprights or standards of suitable strength according to the class of work
for which the apparatus is designed.
These uprights or standards are firmly braced together by diagonal struts or
otherwise, and about midway between the top and the base slides a movable
horizontal platform for the purpose presently described.
This platform is hinged to a falling shutter suspended at the back of the
apparatus and is operated by a system of levers in such a manner that it can be
moved backward and forward as required.
The same system of levers also operates a suitable overhead arm fulcrumed
on the top of the frame and swinging forward over the front of the apparatus,
and carrying by means of a chain or otherwise a suitably designed cage in which
the sack is hung, and held open while being filled.
From an arm on one of the side uprights or standards of the frame is sus-
pended a balance beam carrying a scale or weight dish at one end, and a hook
at the opposite end which engages a ring in top of the cage.
During the filling of the sack, the sliding platform is held back free of the
space between the uprights or standards and when the sack is filled, and weighed,
the hook end of the balance beam is disengaged whereupon the system of levers
being operated by hand, the cage is hoisted until it rises above the plane of
the sliding platform which latter being simultaneously disengaged slides into
position and receives the cage from which the sack can readily be slung on to a
man's shoulder, or otherwise removed for loading purposes.
In order that the nature and operation of my said invention may be more
readily understood, and carried into practice, I will describe the accompanying
drawings.
Fig. 1 represents a front elevation of my improved filling, weighing and load-
ing apparatus.
Fig. 2 is a side elevation shewing the system of levers, and the apparatus
generally, in its normal position while a sack is being filled.
Fig. 3 is a similar elevation shewing the position of the system of levers and
the apparatus generally, when the filled sack is hoisted on to the sliding plat-
form.
Fig. 4 is a plan of the apparatus having regard to its position as represented
in Fio 2

page_text: Similar letters of reference indicate corresponding parts in each of the views.
A represents the frame of the apparatus, B the horizontal platform sliding on
the bars B, and hinged to the falling shutter C, which latter is hinged to the
top of the frame, and the function of which is simply to carry the sliding platform
D is the overhead arm oscillating on the spindle D' to the free end of which
is suspended the cage D².
This cage consists of vertical rods 2, 3 and 4 with arched tops and an arched
stay 5, and is provided with hooks 6, for the reception of the rings usually
attached to the open edge of the sack.
E is the balance beam suspended from the arm E¹ and carrying one scale or
weight dish E the opposite end being provided with a hook E3 which engages
the chain ring of the cage. On the right end of the spindle D¹ is keyed a lever D³
which is pivotably connected to the link 7, which latter is in turn pivotably con-
nected to the end of the two links 8 and 9, the former of which is fulcrumed
to the frame of the apparatus at 10, and the latter to the hand lever 11, working
on the fulcrum 12.
To the hand lever is also pivotably connected the link 13, which acting on the
falling shutter C operates the sliding platform B.
Provision is made for a certain amount of travel in the link 13, by being con-
nected to a lever 14, at the back of the falling shutter and working in a hori-
zontal bracket 15, (Fig. 4) whereby the cage is hoisted clear, before the arrival
of the sliding platform in position.
As thus constructed and arranged the action of my invention is as follows:
The apparatus as shewn in Figs. 1, and 2 is ready to start work.
-
Having hung the sack on the rings 6, of the cage and filled and weighed same,
the balance beam is disengaged and the hand lever 11, pressed down, whereby
the system of levers and links is moved to the position shewn in Fig. 3 which
movement accomplishes the double function of hoisting the cage (with the filled
sack) and shooting forward the sliding platform at the same time.
The hand lever is now slightly released whereupon the cage is deposited on
the platform and the sack being disengaged from the hooks (6) may be readily
and conveniently removed for loading or otherwise. The platform holds the cage
and sack until removal of sack.
The lever is then raised and the apparatus resumes its normal condition.
It is understood that the sliding platform is arranged at a convenient distance
from the ground so as to permit of the sack resting thereon and being readily slung
on to a man's shoulder. It is also understood that the apparatus may be used
without the weighing balance, when this is not necessary, and greater speed of
working is desirable.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I desire to have it
understood that what I claim is:-
In the process of filling, weighing, and loading sacks of grains, coal, or
analogous substances, the use and application of apparatus constructed, arranged
and operating substantially in the manner herein specified and illustrated in
the accompanying drawings.
