Improvements in or connected with Straw Trussers and Binders.
A communication by OTTO CORDES, of Pyrmont, in the Empire of Germany,
Machine Manufacturer.
I, William Phillips Thompson, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, & 6 Bank Street,
Manchester, both in the County of Lancaster, & 323 High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The guards hitherto employed for straw-binding apparatus have all the drawback
that they are at any time liable, whilst in operation, to be voluntarily or
involuntarily pushed back- by the attendants, whereby accidents and damages
easily happened to the attendants.
Endeavours have been made to remove this drawback by connecting the guard
of the binder in such a way with the driving wheel of the latter that, when the
guard is pushed back, the driving wheel of the binder is simultaneously thrown out
of gear. But even this arrangement does not entirely protect the attendant against
being injured by the binding apparatus, because, whilst in the act of pushing back
the guard, the workman may be easily caught and injured by the needle of the
binding mechanism which is still moving at the moment; that is to say, the binding
mechanism is only entirely thrown out of action when the guard has been
completely pushed back.
Any danger of injury from the binding mechanism is entirely avoided by this
invention, because the guard can only be pushed back after the binding apparatus
has been entirely thrown out of action.
For this object, the guard consists of a fixed upper part and a movable under
part with two side walls, both of which parts may be pushed one over the other,
and, at the same time, the movable part is secured in an adjusted position by
means of a fastening device which is operated by the mechanism which throws the
driving wheel out of gear.
On the accompanying drawing
-
Figure 1 shows a side view of a straw-binder with a guard, and
Figure 2 is a partial end view of the same.
Figure 3 is also a partial end view but with the lower part of the guard
pushed back.
Figures 4 and 5 show separate views of the fixing device connecting with
the guard.
a is the driving wheel of the straw-binding apparatus operated by means of a
chain or the like from the thrashing machine. This driving wheel may be
connected with or disconnected from the driving axle of the binder by means of a
suitable coupling. b is the lower part of the guard covering pivotted at c, and 6¹¹
is the fixed upper part of the same, both of which parts, when drawn out in
contrary directions, cover the binding mechanism, but, when pushed over one
another, expose the same.
e,
is
The lever d, for throwing the machine out of gear, which is pivotted at
connected with the coupling of the driving wheel a, and this lever d is further
flexibly connected with a second lever g. This latter is pivotted in a bearing i
arranged in the case of the binder, and has, at its free end, a peg like projection k,
Figures 2 and 3, which engages, according to the position of the lever, in a hole h
formed in the side wall 6' of the movable part 6 of the guard, and thereby holds
this part in its position.

page_text: If it be desired to inspect the binding mechanism covered by the movable part b
of the guard, the projection of the lever must be first removed from the side
wall 6, and this is only possible when the binding apparatus has also been thrown
out of gear by means of the lever d. When this has been done, the projection k
comes, by reason of the flexible connection of the lever d with the lever g, out of
the hole in the side wall of the movable part 6 of the guard, and the guard
plate is released and can be folded over the fixed part of the guard 6.
The movable part of the guard of the binder is thus, when pushed back, always
fixed, and can only be moved by the attendant after the binding mechanism has
been thrown out of gear. On the other hand, the binder cannot be thrown into
gear when the guard is pushed back, because the projection k encounters the closed
side wall of the guard, and thus prevents an intentional or accidental starting of
the binding mechanism.
Figure 4 of the drawing shows a somewhat modified form of the fixing device
for the movable part of the case b. In this case, the lever d, for throwing the
apparatus out of gear, is connected with an elbow lever m, which again, in its turn,
actuates a spindle n arranged in the wall of the binding, apparatus, and this spindle
has, at its upper end, a projection which engages in the hole in the cover before
mentioned.
Figure 5 shows still another modification of the fixing device in so far as, in
this case, the lever d, for throwing the machine out of gear, is connected with a
rack gearing m³, and this latter actuates the spindle n with its projection k for
engaging in the hole h in the wall of the case.
It will be apparent, without further explanation, that, by arranging the guard
case with a fixing device of the patterns hereinbefore described, any accident to
the person attending to the apparatus, arising from the binding apparatus, is
entirely prevented. The workman can only get at the binding mechanism when
the machine has been entirely put out of gear, and the binder itself cannot be
again set in action until, by the drawing down of the part b of the guard, the
working parts of the binding mechanism are covered.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. A fixing or locking device for the guard case of straw trussing and binding
apparatus, which is dependent on the disengaging lever of the driving wheel
coupling with the spindle of the binder, consisting in the flexible direct connection
of the disengaging lever d with a lever g, which latter can engage in a hole h of
the wall b¹ of the guard case by means of a projection k, Figures 1 to 3.

2. A modification of the device described in Claim 1, consisting in the flexible
connection of the lever, for throwing the machine out of gear, with the lever
having the projection k, by means of a spindle n attached to the wall ¹ of the case,
and of an elbow lever m, Figure 4, connected therewith, or rack gearing m¹,
Figure 5.
