Improvement in Hay and Straw Trussing and Pressing Machinery.
GEORGE WOODVILLE Hay Trusser Brook Iron Works Charles Street Manchester in
the county of Lancaster do hereby declare the nature of this invention to be as follows:
In carrying out my invention I construct a side frame by preference of wood
& upon either side of these frames in suitable brackets I mount an horizontal shaft
and provided with two drums or barrells conical shape so the large end gives an
increase of speed round which passes two chains which are designed to give
movement to a platform working in suitable guides by means of the chains passing
over two pullies fixed in suitable brackets at each end on the upper part of the frame.
The drum shaft may be turned in two ways.
1st. I key on one end of the shaft a toothed wheel which is in gear with a small
pinion which may be turned by a wincher handle.
2nd. I key on the same shaft a ratchet teeth wheel fitted with fork levers &
catch resting on
cams and when lever brought forward the catch enters in gear
In the same
with the ratchet so pressed downward gives the greater preasure.
ratchet is geared pawl to attain the preasure while the truss being tied up after
which the pawl is raised by means of a lever and the truss is released.
Rising from the front of the frame and passing backward to a point two thirds
towards the back of the frame I arrange a quadrant nearly the full width of the
machine and from a cross bar passing through the centre line of this quadrant I
hinge a lid or flap designed to act as the top of the press as hereinafter described.
This lid is provided with handles passing through slots formed in the quadrant and
the frame is provided with catches so as to lock the lid in position when at its
lowest point. Working on studs mounted on the outside edge of these handles are
a pair of pinions working in racks formed at either side of the quadrant. The
pinions and racks being designed to keep the lid herein before mentioned in position.
The under side of this lid is further provided with groves or indentations to
receive the tubes hereinafter described. From a cross bar mounted about midway
between the centre line and the circumference of the quadrant I hinge a movable
table to receive the hay or straw to be pressed or trussed. This table is arranged
to move between walls so as to prevent the hay or straw falling off at the sides.
Underneath this table and at a point about one-third from the front of the frame
I mount a horizontal shaft (which may be worked by a ratchet ore in any other
suitable manner) provided with pinions at each extremity which pinions gear into
& work a pair of racks mounted in suitable guides at each side of the frame.
These racks are provided with a cross bar upon which are mounted two three or
more horizontal tubes these tubes being designed to receive the string or wire with
which the truss of hay or straw is to be tied. Extending along the front of the
frame I arrange a bolt to hold the string or wire in position while tied.
The action of this machine is as follows:-The strings or wires are pulled through
the tubes & placed upon the platform the ends being held by the bolts herein before
mentioned and the hay or straw to be pressed or trussed is placed upon the
movable table and upon this table being lifted the hay or straw is caused to fall
upon the platform the table being returned to its original position the lid is then
brought over and locks itself in position by means of the catches herein before
mentioned. The tubes are then worked forward & the strings or wires placed in
position after which the preasure is applied by means of the ratchet raising the platform
and the strings or wires are then fastened. The catches are now released and the lid
raised when the truss may be removed & the machine is again ready.

Improvement in Hay and Straw Trussing and Pressing Machinery.
GEORGE WOODVILLE of 57 Keppel Road, Chorlton-cum-Hardy, in the county of
Lancaster, Hay Trusser, formerly of Brook Iron Works Charles Street, Manchester
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 relates to machines for trussing and pressing hay, straw and other
analogous substances, and consists in the general construction and arrangement of
parts and mechanism thereof. The carrying out of my invention will be readily
understood from the following statement, and having reference to the accompanying
drawings which occupy three sheets.
In my improved machine, I propose to construct a frame, by preference of wood, as
or similar in form to that shewn in figures 1, 2, 3 and 4. Figure 1 represents the
side and figure 3 the front elevation of my improved machine. Figures 2 and 4 are
similar views in section shewing the internal construction. The body of the machine
consists of a cage or box in which the hay or straw is pressed.
The press top or lid (A) figures 2 and 4 is of rectangular form; by means of two
or more levers or extended sides (a) a hinge or joint (a³) figure 2 is formed whereby
the lid may be elevated when required.
The back interior wall (B) has vertical openings or slots (b) figure 4 to allow the
tying material to pass round the truss during operation. Four openings are here
shewn but the number may vary according to requirements.
The side walls (B¹) figures 1 and 2 have each two openings (b).
The press bottom (C) figures 2 and 4 is similar in construction to the lid (A) but
having in addition two longitudinal bars (c) figures 2 and 4 which extend through
the openings in the side walls and to which are attached the chains (D) represented
by the broken lines in figures 1 and 3, for elevating the same.
Upon the inner sides of the press top (A) and the bottom (C) are formed transverse
grooves (a¹) figure 4 designed to allow the passage of the binding strings while the
material is under pressure.
The upper front wall (E) curves backward to a suitable radius.
A door (F) binged at its lower edge (see figure 2) forms an inner wall and falls
upon the platform (G) when required as shewn by the broken lines.
Two levers (H) figures 1, and 4 are hinged to the upper portion of the lid (A)
and are intended for the purpose of pushing up the lid and lowering the same previous
to applying pressure from below. These levers (H) have a suitable catch to lock the
joint, each, and render them rigid while pressing the lid home. The method of
locking here shewn consists in slotting the lever at the joint (h) figure 2, in order
that it may be pushed into a strap or clip (h) fixed also to the lid.
In the front wall of the machine are provided slots (e) figures 3 and 4, through
which the levers protrude, and move therein.
Upon the top of the frame is mounted a shaft (I) figures 3 and 4 having two
grooved wheels keyed thereon. To the smaller wheel (i) one end of a chain (3)
figure 2 is connected, the other extremity being jointed to the lid (A). From the
periphery of the outer wheel (¹) is suspended by means of a chain or cord, a
weight (W) in order to balance the lid (A). (A³) figure 2 shews the position of
the lid with levers when elevated.
To the front of the machine are hinged two doors (K) (K') figures 2 and 3.
One door may be employed alone, but I propose to use two as being more convenient
when in operation. The upper door (K) is hinged upon its upper edge; the lower
one (K) being hinged on its left hand side. These doors are also provided with
openings (k) to facilitate the tying up of the trusses.
In order to secure the doors when closed, a flat bar (1) figure 3, is hinged on
the lower door at (1) figure 3, or to the frame, or otherwise connected, and covers

page_text: a portion of both doors when in position as shewn. The lower door is further
secured by means of a fixed bar at (). In connexion with these bars I employ a
double catch of any suitable construction and mechanism, also operated by the
lever (L) figures 1 and 3 when in a certain position, or otherwise. A form of
double acting catch is shewn at (k) figures 1 and 3.
In the lower part of the frame upon journals I mount a horizontal shaft (M)
having keyed on near each end a drum or cone spirally grooved or otherwise.
On the upper part of the frame on each side I mount two pulleys or rollers (m)
figures 1 and 3, and to the projecting bars (c) of the press bottom I attach corre
sponding rollers (m¹) in any convenient manner. To the frame above the apper
rollers (m) I attach the two ends of a chain, or of two chains jointed together
at (n) figure 1. which I arrange to pass over the rollers in the manner shewn in
figure 1, and on an enlarged plan in figure 5-sheet 3.
From the junction at (n) I carry a chain downwards to the drum (M¹) to which it
is connected.
The drum shaft (M) may be turned by any convenient mechanism, but at present
I propose to employ a forked lever (L) and ratchet wheel (L') upon the drum
shaft (M) on the right hand side of the machine. In connexion with this lever one or
two sliding catches or pawls are employed, which engage in the ratchet wheel (1)
and the lever when pulled forward thereby rotates the drum shaft. The winding in
of the lower chain round the drun elevates the press bottom (C). When the lever (L)
is pushed back a cam or swelling is arranged to raise a sliding catch out of gear with
the drum shaft, to renew its hold. If a pawl be employed it rises and engages auto-
matically. A second catch is employed to retain the hold obtained, whilst the first
re-engages the ratchet wheel, and which may be released by the foot or in any suitable
manner.
On each side of the frame is arranged a channel (P) figures 1-3 and 4 in which is
placed an inverted rack terminating with a handle at its forward end. A transverse
bar connects the two racks at their furthur extremity. This arrangement is shewn
enlarged in figure 6 sheet 3. Fixed to the transverse bar (P¹) are a number of
tubes (p); four are here shewn. These racks are of a length according to the width
of the press lid (A), and are designed for the purpose of carrying the tying up material
over the top of the truss while under pressure. For this purpose the transverse
grooves upon the under side of the lid (A) are formed.
To the bar (P) Figures 6 and 7 are also fixed two bolts (p) which when drawn
forward by the handle (p) pass through the tunnels (0) formed on the upper side of
the lid (A) into sockets or bolt holes in the frame thereby locking the lid to enable it
to withstand pressure from below.
In order to insure the uniform working of the tubes and bolts the racks are provided
therefor, and in connexion therewith a horizontal shaft (R) carrying two toothed
wheels (R) to engage therein is provided.
At the rear of the machine is an elevated platform (S) figures 1 and 2 upon which
the hay or straw is received previous to passing into the press. This platform is
hinged to the framwork for folding up purposes and transport, for which also an axle
and wheels and shafts are provided.
(T) Figures 1 and 2 is a box provided for holding the tying up material from
which it is passed upward to the tubes (p).
For the purpose of holding the strings in position, spring clips made and arranged
in any suitable manner are provided.
Having now particularly described and ascertained the nature of my said
invention and the manner in which the same is to be performed, I declare that
what I claim is :-
1st. The general construction of the machine and arrangement of parts and
mechanism thereof, as and for the purposes set forth and indicated hereinbefore and in
and by the accompanying drawings.
