My invention relates to improved apparatus for holding bags or sacks while they
are being filled.
In carrying my said invention into practice I provide, in combination with a
spout having a lip or projection at one side thereof, a lever for actuating one or
more arms or prongs at the opposite side of the said spout; this lever is made
with a segmental rack with which a latch, pivotted to the spout or in any other
convenient manner, is adapted to engage.
I prefer to fix two prongs on a shaft to one extremity of which is fixed the said
lever, and to place this shaft in suitable bearings at the front of the spout. And I
usually arrange the lever and catch at one side of the spout in such a position that
they can be easily manipulated I also provide a guide for the said latch and means
for preventing it from being moved too far. To form the said lip or projection the
end of the spout may be bent outwards at the rear.
The mouth of the sack is placed over the lower end of the spout and over the
said prongs; the said lever is then actuated to stretch the mouth of the sack taut
and is held in such position by the latch engaging with the segmental rack.
When the apparatus is to be used for sacks to be filled with flour or other
material in the form of dust or powder, I prefer to employ, instead of the prongs
above described, a piece of sheet metal or other suitable inaterial of the same width
as the spout and folded over the sides of the same, if desired.

I, JOHN BENJAMIN STONER, of Blackfriars Road, in the County of Surrey,
Mechanic do hereby declare the nature of my invention for "IMPROVEMENTS
IN APPARATUS FOR HOLDING BAGS OR SACKS WHILE BEING FILLED and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention relates to improved apparatus for holding bags or sacks while they
are being filled with flour, grain, coal or other materials, either from a chute or
spout, or by hand.
My said invention consists essentially in the combination, with a chute or spout,
or with a frame supported in any suitable manner, of one or more arms or prongs
carried thereby, and pivotted thereto, and means whereby the said arms or prongs
can be adjusted and maintained in position relatively to a lip or projection on the
said chute or frame, so that the said arms or prongs, and the lip or projection, will
hold the mouth of a sack open while the said sack is being filled.
In the accompanying drawing I have shewn two forms or modifications of my
apparatus.
Figure 1 is a side elevation, and
Figure 2 a front elevation, of the lower part of a chute or spout with my
apparatus applied thereto.
Figure 3 is a side elevation, and
Figure 4a front elevation of my apparatus designed to hold bags or sacks while
being filled by hand, and
Figure 5 is a side elevation shewing the position of some of the parts when
holding a sack.
Like letters indicate corresponding parts throughout the drawing,
a, a are the arms or prongs, which are fixed on a shaft b carried in bearings c.
In the apparatus shewn in Figures 1 and 2, these bearings are attached to the chute
or spout d; in the apparatus shewn in Figures 3, 4 and 5, they are attached to a
fraine c. A lever or handle fis fixed on one end of the shaft band is provided
with a segmental rack g. A lever h having a catch or tooth i is pivotted on a pin
or stud fixed in one side of the chute or spout, or in an arm e¹ attached to the
framo €, in such a position that the said lever can be easily manipulated The
catch or tooth is arranged to engage with one or other of the teeth of the
segmental rack g. To prevent lateral movement of the lever h I either provide a
guide firmly attached to the chute d, as shewn in Figure 1, or I bend the catch i
downward on the outside of the rack y as shewn in Figure 4.
The arins or prongs a are arranged to operate in combination with a lip or
projection ke formed either upon the chute or spout d, or upon the frame e.
The mouth of the sack is placed over the said lip or projection and over the arms
or prongs a, which are then moved outward by the lever or handle to stretch the
mouth of the sack taut. The said arms or prongs, and the lover f, are then
maintained in position by the engagement of the catch or tooth i with one of the
teeth of the segmental rack g. To release the sack, the lever is raised to
disengage the said catch or tooth from the rack g, and permit the arms or prongs
to resume their original position.
In the apparatus shewn in Figures 3, 4 and 5, the frame e is made with its front
portione adjustable to adapt it for bags or sacks of different sizes, that is to say,
the said front portion is provided with slots e through which are passed the bolts e'
for securing it to the fixed portion of the said frame.

page_text: This frame is carried by two curved arms pivotted at to the brackets m
which are secured by bolts to the standards . These standards are rigidly
attached to a stand or carriage o provided with wheels o' to facilitate its removal
from place to place.
p is a platform arranged above the stand or carriage o and adjustable to adapt
the apparatus for sacks of different depth.
I provide for the adjustment of this platform as follows, viz:—I attach racks g to
the standards n by bolts or otherwise, and I provide the platform 2 with teeth p¹
to engage with the teeth of the said racks. Moreover I secure metal straps p³ to the
said platform, which straps are curved in such a manner that, by raising the
free end of the platform, the teeth p¹ will be disengaged from the racks and the
said platform can be easily raised or lowered upon the standards n and adjusted
according to the depth of the sack to bo filled.
The brackets m are made with slots m² so that they can be adjusted vertically
according to the depth of the bag or sack to be filled. The said brackets also have
curved slots m², into which project the pins or studs on the curved arins l, so that
when a sack has been filled and released, the frame e can be moved backward to
the position shown in dotted lines in Figure 3, to permit the removal of the sack
from the stand or carriage o or from the adjustable platform 2).
When my apparatus is to be used for sacks to be filled with flour or other
material in the form of dust or powder, I prefer to attach to the prongs above
described, a piece of sheet metal or other suitable material of the same width as
the frame or spout and folded over the sides of the same if desired; or I use the
piece of sheet metal as a pivotted arm to operate in combination with the lip or
projection. This piece of sheet metal serves to prevent the escape of the flour
or similar material.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
First. The combination, with the chute or spout or the frame, of one or more
arms or prongs pivotted thereto, and means for adjusting the same and holding
them in position relatively to a lip or projection on the said chute or frame,
substantially as, and for the purpose, set forth.
Second. The improved apparatus consisting of the parts constructed and combined
substantially as described with reference to Figures 1 and 2, of the accompanying
drawing, and arranged to be operated as, and for the purposes, specified.
