PROVISIONAL SPECIFICATION.
Improvements in Means for Attaching Sacks or the like to the
⚫ Spouts of Thrashing Machines, and for other analogous
purposes.
I JAMES MARSHALL of Britannia Iron Works Gainsborough, in the County of
Lincoln Engineer do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide a ready means of attaching sacks, or
the like, to the spouts of thrashing machines, or for other analogous purposes.
I will describe my invention as applied to thrashing machines from which its
analogous applications will also be understood.
According to my invention I provide on the machine, at the back of the spout,
a bracket, having a projection, or lip, to hold one side of the sack I also provide a
clip, or gripper, to hold the other side of the sack in front of the spout. This
clip, or gripper, may be attached to the rod over the spout which usually carries
the hooks for hanging up the sacks. The said clip, or gripper, has jaws which
close on the sack and hold it securely in position. The jaws may be forced
together by a device such, for example, as a spring, or a lever, or cam. When a
spring is used for the purpose I provide a catch which acts automatically to hold
the clip, or gripper, open to receive the sack, and when I employ a lever, or cam,
I provide a spring to open it, so that, in either case, the attendant, when holding
the sack in one hand, can readily operate the clip, or gripper, with the other
hand.
I construct the parts of the sack holder so that they can conveniently be applied
to existing thrashing machines without any special provision, or alteration, of the
machine.
The apparatus is used as follows:-,
One side of the sack is passed over the lip, or projection, at the back of the spout,
the opposite side being drawn within the jaws of the clip, or gripper. If the
latter be spring closing the catch is released and the jaws of the clip, or gripper,
close on the sack, holding it firmly in position. When the clip, or gripper, is
operated by a lever, or cam, the attendant closes the said clip, or gripper, by
pulling the handle provided for the purpose, by which means the jaws of the clip,
or gripper, are closed firmly on the sack, and remain so until the reverse movement is
given to the handle, when the jaws are opened by the spring.

Spouts of Thrashing Machines, and for other analogous
purposes.
I, JAMES MARSHALL, of Britannia Iron Works, Gainsborough, in the County
of Lincoln, Engineer, 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:-
The object of my invention is to provide a ready means of attaching sacks, or
the like to the spouts of thrashing machines, or for other analogous purposes.
I will describe my invention as applied to thrashing machines from which its
analogous applications will also be understood.
Figures 1 and 2 of the accompanying drawings are views at right angles to each
other of a device made in accordance with my invention the said device being in
the open position.
Figure 3 shews the device in its closed position.
-There is provided on the machine, at the back of the spont, a bracket, having a
projection, or lip, to hold one side of the sack. The device according to this
invention consists of a clip, or gripper, to hold the other side of the sack in front
of the spout, the said clip, or gripper, being preferably attached to the rod over
the spout which usually carries the hooks for hanging up the sacks. The said
clip, or gripper, has jaws A B the jaw B turning on a hinge pin at a and the jaw A
being formed with an eye b by which the device is attached to the rod or part to
which it is to be secured it being held in place by the pinching screw 63. Thus the
device can conveniently be applied to existing thrashing machines without any special
provision, or alteration, of the machine. The jaw B can be forced towards the
jaw A by a lever C centred at c to a lug formed on the jaw A. The spring D is
placed in recesses formed on the inside of each jaw and tends to move the jaw B
away from the jaw A so that the attendant, when holding the sack in one hand,
can readily operate the clip, or gripper, with the other hand. The lever C passes
through slots in the jaws and is provided with a V piece at 2 which engages with
notches on the jaw B.
The apparatus is used as follows:-
One side of the sack is passed over the lip, or projection, at the back of the
spout, the opposite side being drawn within the jaws of the clip, or gripper. The
attendant then presses down the lever C and so moves the jaw B towards the jaw A
so as to grasp the sack between the jaws, the engagement of the V piece c² on the
lever with the notches 63 in the jaw B holding the jaw B in the closed position
until the reverse movement is given to the lever C, when the jaw B is moved
outwards by the spring D and the sack can be removed.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A device for attaching sacks or the like, the said device consisting of
jaws provided with a lever for closing the one jaw against the other and a
spring for separating the one jaw from the other substantially as hereinbefore
described.

page_text: 2. A holding device for sacks or the like constructed as hereinbefore described.
and illustrated in the accompanying drawing.
