Improvements in Apparatus or Devices for Compressing Stacks of
Hay, Ensilage, or the like.
I JOHN EDWARD LEUTY of 69 and 71 Bird-in-Bush Road Peckham in the County
of Surrey Cowkeeper do hereby declare the nature of this Invention to be as
follows:
-
My Invention has for its object to provide apparatus or devices for compressing
stacks of hay ensilage or the like which apparatus or devices can be readily and
equally adjusted so that the pressure can be brought to bear very efficiently throughout
the whole extent of the stack. The arrangement is such that it can be adjusted and
the pressure applied by hand horse or steam or any other convenient power.
According to my Invention I provide a number of bands or strips which are pre-
ferably in detachable lengths so that I can use more or less of them in accordance
with the size of the stack. These are to be passed over the top of the stack. Along
the top of the stack 1 secure a strip with guides upon it to keep the bands aforesaid at
proper distances apart and in position. To the ends of these bands I attach one end
of a device whose other end is attached to a sling placed round a timber of which
there are a series arranged under the stack and transversely to it with their ends pro-
jecting therefrom. This device consists of two members which slide in or over each
other so that they move closer together so as to occupy a less space lengthwise when
the stack is being compressed but so that they retain their engagement in such way
that when the pressure employed to draw down the bands is released the said device
will not move outwards again but will retain the bands in the position to which such
pressure has brought them. 1 will describe more particularly an arrangement
according to my Invention premising however that I do not limit myself to the precise
details which I shall describe I will describe one set of bands and devices it being
understood that there is a set of such appliances situated at suitable distances apart
along the length of the stack. I connect each end of say three of the jointed bands
together by means of hooks on the upper side of a yoke which carries on its lower side
another hook to which I hook one member of the connecting device the other member

page_text: of which is connected by a hook to a sling passed around the end of one of the pro-
jecting timbers aforesaid. This device may be a pair of plates one with a series of
slots in it and the other with a projection on it so that as the compressing pressure is
put on the bands the members of this device move over each other and the projection.
When the limit of compressing pressure has been applied it will engage with the slot
which is opposite it and the bands will consequently when the compressing pressure is
removed not yield to the pressure of the stack but will retain the position given to
them during the application of the compressing pressure. Or I may use a rod passing
into a tube the latter being provided with toothed cam pieces or grippers turning on
centres on the tube and engaging with notches on the side of the rod to perform the
same office as the two members in the preceding example. There may be a device of
this kind at each side or at one side only of the stack.
When pressure is to be put on the stack I draw down the bands from one or both
sides which I may effect by attaching a rope to the lower hook of the yoke and
passing it under a pulley which I secure to the aforesaid projecting end of the timber
and when I desire to pull from both sides at once I attach a rope also to the lower
hook of the yoke on the other side and I bring this last named rope under a pulley
placed on the projecting end of the timber at that side and pass it under the stack to
the other side (preferably through a tube provided for the purpose) so that the two
ropes can be drawn upon at once and so the bands be pulled down from each side. It
is understood that this arrangement is repeated in a series side by side along the
stack I prefer to apply the compressing pressure to one set of bands only at a time.

1 JOHN EDWARD LEUTY of 69 & 71 Bird-in-Bush Road Peckham in the County of
Surrey Cowkeeper 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:-
My Invention has for its object to provide apparatus or devices for compressing
stacks of hay, ensilage or the like, which apparatus or devices can be readily and
equally adjusted so that the pressure can be brought to bear very efficiently throughout
the whole extent of the stack.
The arrangement is such that it can be adjusted and the pressure applied by hand,
horse or steam or any other convenient power.
According to my invention I provide a number of bands or strips or lengths of hoop
iron or its equivalent preferably made in lengths capable of being readily connected
together and detached from one another so that I can use more or less of these lengths
according to the size of the stack. These bands or strips are passed over the top of
the stack to be compressed, along the top of which stack I secure a strip having
notches or recesses into which the bands are placed the said notches or recesses
serving as guides to adjust and keep the bands in position at proper distances apart.
These bands are connected at their ends either singly or in clusters of any desired
number (preferably three) to yokes to each of which I attach one end of a pressure
retaining device the opposite ends of which devices are attached to slings or loops
placed round the protruding ends of tubular or other suitable supports or attached
directly to the said supports of which there are a series arranged transversely under
the stack. These pressure retaining devices each consists of two members which slide
in or over each other so as to occupy a less space lengthwise when the stack is being
compressed but so that they retain their engagement in such way that when the
pressure employed to draw down the bands is released the said device will not move
outwards again but will retain the bands in the position to which such pressure has
brought them. I will describe more particularly with reference to the accompanying
drawings an arrangement according to my invention premising however that I do not
limit myself to the precise details which I shall describe. Figure 1 of the drawings
is a side elevation of a portion of a stack of ensilage under compression according to
my invention and Figure 2 is a transverse section of the same. Figure 3 is a detached
view of one of the pressure retaining devices hereinafter referred to. I will describe
one set of bands and retaining devices it being understood that there is a set of such
appliances situated at suitable distances apart along the length of the stack. The
bands A are each preferably made up of a number of lengths of hoop iron or the like

page_text: connected together so as to be capable of being readily lengthened or shortened
according to the size of stack to be compressed. Along the top of the stack I place
a strip or bar A¹ having notches or recesses a¹ into which the bands are placed the
said notches or recesses serving as guides to keep the bands at the requisite distance
apart. I connect each end of say three of the jointed bands together by means of
hooks a on the upper side of a yoke B which carries on its lower side another hook b
to which I hook one member c of the pressure retaining device C the other member d
of which levice is connected by a hook d to a sling D passed around the end of one
of the projecting timbers or tubular supports E placed transversely beneath the stack
or if desired it may be connected directly to the said support. The member or rod c
of the retaining device C slides in the other member or tube d and the latter is pro-
vided with toothed cam pieces or grippers F turning on centres f on the tube d which
grippers engage with notches or roughened surfaces on the sides of the rod c so that
when the said rod is drawn into the tube d during the compression of the stack the
cain pieces or grippers will engage the rod and retain it in position. There may
device of this kind at each side or at one side only of the stack.
be a
When pressure is to he put on the stack I draw down the bands A from one or both
sides which I may effect by attaching a rope for the like to the lower hook of the
yoke B and passing it under a pulley e secured to the projecting end of the timber or
tubular support E and when I desire to pull from both sides at once I attach another
rope for the like to the corresponding lower hook of the yoke B on the other side
of the stack as shown in Figure 2 and I bring this last named rope under a pulley e²
placed on the projecting end of the timber or tubular support E at that side and pass
it through the said tubular support or through a separate tube provided for the
purpose to the other side so that the two ropes f2 f³ can be drawn upon at once by
means of a windlass, horse work or other power and so the opposite ends of the bands
will be simultaneously pulled down from one side of the stack. It is understood that
this arrangement is repeated in a series side by side along the stack, I prefer to apply
the compressing pressure to one set of bands only at a time.
Instead of or in combination with the pressure retaining device Cherein before
described a pair of plates c and d as shown at G in Figure 1 and in detached view
Figure 3 may be employed. One of these plates (d) has slots 2 in it and the other
plate c is provided with a projection d¹ so that as the compressing pressure is put on
the bands A the members c and d of this device move over each other and when the
limit of compressing pressure has been applied the projection d' on the plate c will
engage with a slot c2 in the plate d which is opposite it and the bands will consequently
when the compressing pressure is removed not yield to the pressure of the stack but
will retain the position given to them during the application of the compressing
pressure as in the arrangement herein before described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. In apparatus or means for compressing stacks of hay, ensilage or the like the
employment of bands, strips or lengths of hoop iron, wire rope or equivalent material
in combination with a notched bar or strip or notched bars or strips on top of the
stack and having recesses therein for engaging the bands or strips so as to maintain
them at the required distance apart while the stack is being compressed substantially
as hereinbefore described with reference to the accompanying drawings.
2nd. In apparatus or means for compressing stacks of hay, ensilage or the like the
combination with bands, strips or lengths of hoop iron, wire rope or equivalent
material of a pressure retaining device or devices consisting each of two members
which slide one over or within the other and provided with hinged or pivotted cam
surfaces for retaining the two members in the position to which they are brought
relatively to each other while the stack is being compressed substantially as herein-
before described with reference to the accompanying drawings.

page_text: 3rd. In apparatus or means for compressing stacks of hay, ensilage or the like the
combination with bands, strips or lengths of hoop iron, wire rope or the like and
pressure retaining devices such as hereinbefore described of tubes or passages arranged
beneath the stack for the passage of a hauling rope from one side of the stack to the
other side substantially as and for the purpose herein before described with reference
to the accompanying drawings.
4th. The general combination of parts constituting apparatus whereby stacks of
hay, ensilage or the like may be equally and simultaneously compressed on both sides
of the stack by power exerted from one side of the stack substantially as hereinbefore
described and illustrated by the accompanying drawings.
