COMPLETE SPECIFICATION.
New or Improved Apparatus for Holding Open the Mouths of Sacks.
We, AUGUST KLESSE, Smith, of 38, Eckersdorf, District, Neurode, and ERNST
Boм, Merchant, of 27, Klein-Mohlten, both in Silesia, 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 apparatus for holding the mouths of sacks open while
the latter are being filled, which consists of a column or stand provided with a
foot or feet and to which is fixed a supporting bow or hoop which may be fur-
nished with spring actuated clamps for holding the sack to be filled.
The accompanying sheet of drawings illustrates an apparatus constructed in
accordance with the invention, Figure 1 being a side view, Figure 2 a plan, and
Figures 3 and 4 a plan and elevation respectively of a modified form of the sup-
porting bow or hoop.
Referring in the first place to Figures 1 and 26 is a stand or column of suit-
able section provided with feet a, and carrying a bow or pair of bent arms c
furnished with an eye or socket d free to slide up or down on the stand or
column and having a set screw e by means of which the said bow or bent
arms & can be secured at any desired height on the said stand or column. The two
ends ii of the bow c are so shaped that they form with the armis hh, connected
with the bow c by means of the links gg, jaw-like clamps. The arms hh are
acted on by springs ff which tend constantly to hold the clamps closed. These
clamps serve to .hold the mouth of the sack in a convenient and handy position
for the insertion of the material to be filled into it. It will be understood that
the bow can easily be adjusted and fixed on the stand or column bat such a
height that the bottom of the sack may rest on the ground.
In the modification shown in Figures 3 and 4 the bow c is made as a spring
hoop, and has rivetted to it downwardly projecting pins k, round which the
mouth of the sack is placed while the hoop c is held in the contracted condition
shown in the figure by means of a spring actuated lever provided with a pin o
which passes through holes near the two ends of the hoop. When the mouth of
the sack has been properly placed round the pins & the lever his operated so as
to withdraw the pin o from the hole in the outer part of the hoop c, and the latter
immediately springs open, and holds the sack securely with its mouth wide open.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
First. An apparatus for holding open the mouths of sacks which consists of a
vertical stand or column b and a bow or hoop c adapted to be fixed at any re-
quired height on the said stand or column, substantially as described.
Second. In an apparatus of the kind forming the subject matter of the first
claiming clause hereof, the employment of an open bow or pair of arms e having
077

page_text: at its ends spring actuated clamps i for holding the sack, substantially as
described.
Third. In an apparatus of the kind forming the subject matter of the first
claiming clause hereof, the employment of a bow or hoop e provided with pins k
and held in a contracted condition by means of a pin o while the mouth of the
sack is being passed round the said pins, and adapted to spring open, and to hold
the mouth of the sack firmly in an open position when the said pin o is with-
drawn so as to liberate the end of the bow or hoop, substantially as described.
Dated this 25th day of April 1898.
