Improvements in Sack Holders for Thrashing Machines, or for
other purposes where Sacks or the like are to be Held and
Filled.
I, JAMES MARSHALL of the Firm of Marshall Sons & Company Limited of
Britannia Iron Works, Gainsborough in the County of Lincoln, Engineers do
hereby declare the nature of this invention (which has been communicated to me
from abroad by Hugo Graepel of Budapest in the Kingdom of Hungary,
Engineer) to be as follows:-
This invention has for its object to provide a holder or device for attaching
sacks or the like to the outlet of thrashing machines or for other analogous purposes,
the holder or device being so arranged that when the sack or the like is secured
the same operation that secures it also opens the outlet whilst when the sack
or the like is to be detached the same operation that releases it also closes the
outlet. This is effected by attaching the valve or part which opens and closes
the outlet to a spindle or shaft operated by a suitable handle and provided with
an eccentric cam or its equivalent so that by moving the said handle to open and
close the outlet the eccentric cam or the like operates upon a clip or clips or the
like to grasp the sack or the like and secure it in position or releases the clip or
clips or the like so that the sack or the like can be removed. The following is a
convenient construction according to this invention.
The body or spout of the sackholder is secured to the outlet from a thrashing
machine or other place to which sacks or the like are to be attached. Upon one
side (preferably the upper side which is flattened) there is a boss or bearing for a
spindle or short shaft to which is secured the plate by which the outlet through
the spout is opened and closed by means of a handle or lever secured to or formed
on the said spindle so that it can have movements of partial rotation imparted to
it. At the other end of the spindle or on the handle an eccentric or cam is fixed
or formed. Two spring clip pieces are mounted at either side of the spindle their
springs tending to open them but the aforesaid eccentric or cam when it is moved
into the position to open the outlet presses upon a cross piece attached to the said
spring clip pieces and presses them down so that they grip the sack between
themselves and the spout or projections thereon. The side of the spout opposite
the clips may be provided with a rib or projection to support the other side of
the sack.

Improvements in Sack Holders for Thrashing Machines, or for
other purposes where Sacks or the like are to be Held and
Filled.
I, JAMES MARSHALL, of the Firm of Marshall Sons & Co Limited of Britannia
Iron Works, Gainsborough, in the County of Lincoln, Engineers, do hereby
declare the nature of this invention (which has been communicated to me from
abroad by Hugo Graepel, of Budapest, in the Kingdom of Hungary, Engineer,)
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 for its object to provide a holder, or device, for attaching
sacks, or the like, to the outlet of thrashing machines, or for other analogous
purposes, the holder, or device, being so arranged that when the sack, or the like,
is secured the same operation that secures it also opens the outlet whilst when the
sack, or the like, is to be detached, the same operation that releases it also closes
the outlet. This is effected by attaching the valve, or part which opens and closes
the outlet, to a spindle, or shaft, operated by a suitable handle and provided with
an eccentric, or cam, or its equivalent, so that by moving the said handle to open
and close the outlet, the eccentric, cam, or the like, operates upon a clip, or clips,
or the like, to grasp the sack, or the like, and secure it in position, or releases the
clip, or clips, or the like so that the sack or the like can be removed. The following
is a convenient construction according to this invention.
I will refer to the accompanying drawings which illustrate an arrangement
suitable for thrashing machines but the spout may be in other position than that
shown.
Fig. 1 is a front elevation, Fig. 2 a plan, and Fig. 3 a transverse section.
Figs. 4 and 5 illustrate the positions when the sack is released and secured
respectively.
The body or spout A of the sack-holder is secured to the outlet from a thrashing
machine, or other place, to which sacks or the like are to be attached. Upon one
side (preferably the flattened upper side) there is a boss or bearing B for a
spindle or short shaft C to which is secured the plate D by which the outlet through
the spout is opened and closed by means of a handle or lever F secured to or
formed on the said spindle C so that the said spindle can have movements of
partial rotation imparted to it by means of the said handle or lever. At the other
end of the spindle Cor on the handle or lever Fan eccentric or cam is fixal
or formned. Two spring clip piece me mounted on the pout A at either le
of the spindle their springs tending to open them or move them away from the
spont but the aforesaid eccentric or can when it is moved into the position to
open the outlet presses upon ero piece attached to the spid spring clip pieces G
teen
themselves and the spout or projections thereon. The side of the spout opposite
the clips may be provided with a rib or projection I to support the other side of
the sack. The operation is as follows:-When the parts are in the position shown
in Fig. 4 the top edge of the sack is laid over the rib or projection H and one
side of the sack is drawn along to the right hand side of the spout and put under
the spring clip piece G at that side and the other side of the sack is drawn along
to the left hand side of the spout and put under the spring clip piece G at that
side. Then the two sides of the top edge of the sack are taken hold of and the
sack is pulled tightly against the body of the spout and then the handle or lever F
is operated so as to cause the eccentric or cam E to bear on the cross piece g so
that the spring clip pieces G are moved towards the spout and grip the sack
alah tomato that the

page_text: firmly between themselves and the spout the outlet for material through the spout
being opened at the same time by the removal of the plate D from before its
opening. When the sack is filled it is taken hold of and the handle or lever F
moved in the opposite direction whereby the eccentric or cam allows the spring
clip pieces G to leave their hold upon the sack and at the same time the outlet
through the spout is closed by the plate D and remains closed until another empty
sack is secured in place on the spout.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A holder for sacks or the like wherein the same operation which opens the
outlet secures the sack or the like and the same operation which closes the outlet
releases the sack or the like substantially as hereinbefore described.
2. A holder for sacks or the like consisting of the combination with the means
by which the outlet is opened and closed of an eccentric or cam or its equivalent.
which operates and releases the sack gripping device, substantially as hereinbefore
described.
3. The arrangement and combination of parts constituting a sack holder
substantially as herein before described and illustrated in the accompanying
drawings.
