An Improved Ditching and Tile Laying Machine.
I, ODILON BALTZAR HANNIBAL HANNEBORG, of Urskoug, in the Kingdom of
Norway, Estate Owner, 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 a ditching and tile-laying machine which I will describe
by reference to the accompanying drawings, in which :-
Figure 1 is a side elevation of the said machine, shewing it in its operating
position.

Figure 11 is a transverse vertical section of the machine.
Figure 12 is a plan view of the steering lever, cords and guide sheaves.
Figure 13 is a side view of the steering lever and cords and the guide and
tightening sheaves.
Figure 14 is a side view and
Figure 15 is a rear view of a part of the tilting mechanism.
Figure 16 is a side view of the supporting folding rails with gearing and
Figure 17 is a section of the same.
A (Figures 1, 2, 3, 4, 16 and 17) is the supporting frame which is rectangular
and mounted upon wheels A which roll on folding rails composed of link shoes A!!!
forming a truss over which the wheels A¹ and A" A" can pass (as shown in
Figures 1, 16 and 17) but in such a manner that the frame A can be tilted
independently of the folding rails.
The tilting of the frame A is effected in the following manner: The worm a
(Figures 14 and 15) is turned by the hand-wheel whereby the worm-wheel c is
moved in one or the other direction as the case may be. On the worm-wheel c is a
small bevel wheel & which on one side is in gear with a segment of a bevel-wheel e
working loose on a shaft, but in one piece with the crank g, to which one end of
the connecting rod h is fastened while the other end of his fastened to the lever i
which is keyed on the shaft j.
The shaft is supported at each end in bearings which are fastened on the frame A.
Near the middle of the shaft jis keyed another lever k which by the short con-
necting rod can hold the frame A in line or at an angle with the beam m, as shewn
by dotted lines in Figure 14.
The other side of the small bevel-wheel d is in gear with a segment of a bevel-
wheel o which is keyed on one end of the shaft while on the other end of the same
shaft is keyed the crank n to which is fastened one end of a connecting rod exactly
like h. The other end of this connecting-rod is again fastened to a lever exactly
like and so on as just described. The small bevel wheel d will by this arrange-
ment act as an evener, so that the folding rails on either side of the machine will
follow the ground although it may be very uneven.

page_text: The link shoe forming the folding rail is so constructed that stones and lumps of
carth or wood cannot fall in between the jaws of any of them, as illustrated in
Figures 16 and 17.
In the interior of the frame A is situated an intermediate frame B which is con-
nected to the frame A by pivots or hinges B¹ B¹ (shewn in Figure 4) and held by
spur wheels A, A working in toothed segments B 13", which latter are bolted
to the frame B. The spur-wheels A, Aare moved by an automatic balancing
device which is so constructed that the frame B will always be held in a vertical
position in line with the trench to be dug and independent of the frame A.
The automatic working balancing-device is shewn in Figures 5, 6 and 7, and is
constructed as follows:-
T is a shaft which derives its motion from the main rear driving sheave or
pulley U as shewn in Figures 1 and 3, in which all indicates a tumbling shaft which,
by the bevel-wheels and c" and the shaft d, on which the bevel-friction wheel e¹
is keyed, can be driven in one or the other direction by bringing e" either in contact
with the bevel-friction-wheel for g" (shown in Figures 3 and 4). These latter
bevel-friction-wheels f" and g" are keyed on to the same shaft as the rear driving
sheave U from which they derive their motion as before mentioned.
On the shaft T (Figures 5, 6 and 7) is fastened a spur-wheel at which drives
another spur-wheel 6' keyed on the shaft c'.
This latter shaft is capable of being moved up and down by the shifting
leverd while the shaft c¹ revolves, whereby the friction-bevel-wheels e', e' will
drive the friction-wheel f¹ in one or the other direction as the case may be.
From the motion will be transmitted through the shaft to the worm
which again drives the worm-wheel segment and thereby the shaft with its
crank To the crank is fastened one end of the connecting rod while
the other end of is fastened to the shifting lever m² whereby the bevel-
friction-wheel n' or o¹ will be pressed against the friction-wheel p¹, which is
keyed to the lower end of the shaft T.
As the friction-wheel revolves with the shaft T the motion will be trans-
ferred to the friction-wheel if this is pressed against p', or to o', if the latter
is pressed against p', whereby the shaft g' is driven in one or the other direction.
On the shaft g are secured two worms, 1 (shewn in Figure 3 and Figure 7)
which are in gear with the worm-wheels s, fastened to the shafts t¹,
(shewn in Figures 7 and 8) whereon are also fastened the spur-wheels A, A
(Figure 11) which work in the toothed segments B, B. In this way the
spur-wheel A, A are made to revolve in one or the other direction by
moving the shifting lever up or down. This movement of the shifting lever d
is effected automatically by the weight (Figures 6 and 7) suspended at the
end of the lever pivotally fastened to the frame which by the rod y' is
always held parallel with the centre line of the frame B. As soon as B comes
out of plump, the frame will also come out of plumb, and the fever, which
is held plumb by weight a', will, through the lever push the shifting lever d
in one or the other direction setting the gears in motion, whereby the frame B
will always be held in a vertical position without the attention of the drivers.
In the interior of the frame B is situated a frame C which carries the ditching,
tile-laying and conveying mechanism hereinafter described (Figures 1, 2, 3, 4, 9, 10
and 11).
The frame C is so arranged that it can be lowered and raised inside the frame B
by means of four pinions or spur-wheels C, C, C', C' which work up and down in
four toothed racks or bridles 13 Bi Bi Bi
The spur-wheels C¹, C, C, C are driven from the rear driving shaft on which
the sheave U is fastened, the motion being transmitted through the bevel-wheels "
and (Figures 3 and 4) and the shaft to the bevel-wheel which drives the
bevel-wheels and m in opposite directions on the shaft n".
and between 2 and m" is a clutch o" which can be shifted from
coupling either of these bevel-wheels to the shaft n", whereby the

to m", thereby
latter will run in

page_text: one or the other direction. On each end of the shaft n" is fastened a worm_p"
and q which are in gear with the worm-wheels and s" (Figure 11) these latter
being keyed on the same shafts as the spur-wheels C, C, C, C¹ before mentioned.
The shifting of the clutch o" is effected by the bell-crank t" (Figure 4) which, by
the rods and can be operated by the hand-lever O.
By these devices the frame C can be raised or lowered to adapt it for transportation
or for work and for varying the depth of the cut.
D is a plough securely fastened to the frame B and intended to clear away
small hillocks or uneven parts of the ground in front of the cutting- and digging-
apparatus proper.
This latter is composed of a sharp-edged screw or worm C" (Figures 4, 9 and 10)
which derives its motion from the front driving shaft C by a pair of bevel-
wheels p and q (Figure 11) and can be started or stopped by means of a
hand-lever (Figure 11) and a clutch s at the will of the upper driver.
The cutter-screw C" is on its rear side covered throughout it entire length by
shield-plates (Figures 9 and 10) which prevent the earth from falling down
behind the cutter-screw. These shield-plates are securely fastened to the frame C.
In order to reduce friction between the cutter-screw and the shield-plate t*, two
rollers u, u are provided behind the cutter-screw near the lower end of the same,
as seen in Figures 1, 4, 9 and 10.
The cutter-screw C₁ is on its front side covered by shield-plates only on that
part which extends above the ground in order to prevent the earth from falling
down in front of the screw. To this end a semi-cylindrical shield E (Figures 4,9
and 10) is supported on the frame B by means of the connecting rod and
hinges E', E and E", so arranged that the shield-plate will press near up
against the screw-cutter by its own weight and, so that it can be pressed up
and away from the screw, if a large stone or lump of earth should be carried
up by the screw allowing such stones or lumps to pass between the screw and
shield-plate without interrupting the work.
As the cutter-screw C" is moving up and down with the frame C, while the
shield-plate E is fastened to the frame B, the earth would fall down as soon as it
had reached the upper end of the shield-plate E whenever the cutter was in a
higher position; to prevent this I place another seini-cylindrical shield-plate F
(Figures 4, 9 and 10) outside the shield-plate E, it being fastened to the frame C
by means of hinges and a spiral spring F in such a manner that the shield-
plate F will be pressed near up against the shield-plate E and the cutter-screw Cl
and so arranged that it will work freely up and down outside the shield-plate E,
at the same time allowing stones and lumps to pass up between itself and the
cutter screw.
G is a conveyor-trough over the bottom of which the belt Gl passes.
The conveyor-trough G reaches from the upper end of the cutter-screw and
passes horizontally straight backward to a directing chute H which is adapted
to be turned either to the right or to the left, so as to throw the dirt escaping
from the trough G either into or out of the ditch or trench dug by the machine
when in operation.
The belt G derives its motion from the roller I which is again driven from the
shaft J by a sprocket-chain K.
L is the seat of the upper driver and M the seat of the lower driver.
The directing chute H can be operated by the lower driver by means of the
hand-lever N.
The raising and lowering of the machine, together with the steering, is effected
by the hand-lever O which is operated by the upper driver.
The starting, stopping and reversing mechanism for the horizontal movement of
the machine is operated by the hand-lever P, which can be reached as well by the
lower as the upper driver.
These mechanisms will be more fully explained later on.

and which are in gear with the worm-wheels and s" (Figure 11) these latter
being keyed on the same shafts as the spur-wheels C', C', C, C¹ before mentioned.
The shifting of the clutch o" is effected by the bell-crank t" (Figure 4) which, by
the rods and can be operated by the hand-lever O.
By these devices the frame C can be raised or lowered to adapt it for transportation
or for work and for varying the depth of the cut.
D is a plough securely fastened to the frame B and intended to clear away
small hillocks or uneven parts of the ground in front of the cutting- and digging-
apparatus proper.
This latter is composed of a sharp-edged screw or worm C₁ (Figures 4, 9 and 10)
which derives its motion from the front driving shaft C by a pair of bevel-
wheels p and q (Figure 11) and can be started or stopped by means of a
hand-lever (Figure 11) and a clutch s at the will of the upper driver.
The cutter-screw C" is on its rear side covered throughout it entire length by
shield-plates (Figures 9 and 10) which prevent the earth from falling down
behind the cutter-screw. These shield-plates are securely fastened to the frame C.
In order to reduce friction between the cutter-screw and the shield-plate t*, two
rollers u, u are provided behind the cutter-screw near the lower end of the same,
as seen in Figures 1, 4, 9 and 10.
The cutter-screw C is on its front side covered by shield-plates only on that
part which extends above the ground in order to prevent the earth from falling
down in front of the screw. To this end a semi-cylindrical shield E (Figures 4, 9
and 10) is supported on the frame B by means of the connecting rod and
hinges E, E and E, so arranged that the shield-plate will press near up
against the screw-cutter by its own weight and, so that it can be pressed up
and away from the screw, if a large stone or lump of earth should be carried
up by the screw allowing such stones or lumps to pass between the screw and
shield-plate without interrupting the work.
As the cutter-screw C" is moving up and down with the frame C, while the
shield-plate E is fastened to the frame B, the earth would fall down as soon as it
had reached the upper end of the shield-plate E whenever the cutter was in a
higher position; to prevent this I place another semi-cylindrical shield-plate F
(Figures 4, 9 and 10) outside the shield-plate E, it being fastened to the frame C
by means of hinges and a spiral spring in such a manner that the shield-
plate F will be pressed near up against the shield-plate E and the cutter-screw C
and so arranged that it will work freely up and down outside the shield-plate E,
at the same time allowing stones and lumps to pass up between itself and the
cutter-screw.
G is a conveyor-trough over the bottom of which the belt G' passes.
The conveyor-trough G reaches from the upper end of the cutter-screw and
passes horizontally straight backward to a directing chute H which is adapted
to be turned either to the right or to the left, so as to throw the dirt escaping

The directing chute H can be operated by the lower driver by means of the
hand-lever N.
The raising and lowering of the machine, together with the steering, is effected
by the hand-lever O which is operated by the upper driver.
The starting, stopping and reversing mechanism for the horizontal movement of
the machine is operated by the hand-lever P, which can be reached as well by the
lower as the upper driver.
These mechanisms will be more fully explained later on.

page_text: The construction of the tile-laying portion of the machine is as follows:-
Behind the cutter-screw C" and on to the shield-plates * are symmetrically
fastened two parallel sheet iron square plates f1, (Figures 1, 3, 4) which
extend from the lower end of the screw-cutter and reach a short distance above
the ground when the ditching mechanism is in its lowest position and reach from
the shield-plates near the cutter-screw and so far back that they will just
clear the frame B when moved up and down. These shield-plates are placed at a
distance apart, which is a little less than the diameter of the cutter-screw, so that
they can pass freely in the trench made by the cutter-screw and prevent the earth
from falling down into the trench before the tiles are laid but far enough apart to
allow the largest tiles used to pass between them.
Between the plates, is fastened a curved guide-plate g¹¹, 91 (Figure 4)
intended to conduct the tiles to the bottom of the trench. The lower end of this
guide-plate has a central rounded point or scorer which marks the bottom of the
trench properly for receiving the tile sections and preventing them from rolling.
sidewise. In order to make sure that tiles of unequal size will come exactly in
line and in the middle of the trench I provide a V-shaped curved guide Q which
will rest on the top of the tiles in the chute between the plates f", "" (as shewn
in Figure 3). The guide Q is curved like 9, and can be moved to and from
it by the hand-lever R which is within reach of the lower driver or tile-feeder. By
raising the lever R the guide Q will allow tiles of larger diameter to pass into the
'tile-chute, but under ordinary working with tiles of the same diameter, the guide Q
will always rest on the top of the tiles and make them come in line before they
reach the bottom of the trench.
This roller s is fastened to a
In order to fill up soft places or cavities in the bottom of the trench and make a
solid bed for the tiles, the machine is provided with an apparatus which will fill
sand in such places. This is carried out, as shewn in Figure 4, where s is a roller
which, by a springs, is pressed against the bottom of the trench directly behind
the shield-plate in the rear of the cutter-screw.
lever pivotted at and connected with the valve which closes the opening
in the bottom of the sand reservoir by the rod . When the roller s reaches
a cavity or soft place in the ground it will sink down into it and open the
valve whereby sand will fall into the funnel m¹ and from thence through the
pipe reach the bottom of the trench, where the roller o will press it into
the cavities, the excess of sand being removed by the plough p. To prevent the
sand from sticking inside the pipe n I provide the latter with a rod 7, which,
being driven by gearing works continuously up and down inside the pipe n
is a cord which reaches from the lever of the valve to a place within
easy reach of the lower driver, so that he can, at any time, stop the flow of
sand by pulling in this cord and then fasten the end of the cord to a book.
The machine, is also provided with an apparatus which will feed a continuous
strip of specially prepared paper on the top of the tiles to prevent earth from falling
in through the opening between the said tiles. This is carried out in the following
manner.
is a rubber band or belt which runs over the rollers and ¹ and derives
its motion from the roller ul which is again driven by the gearing from the shaft J
at such a speed that a strip of paper will be fed down to the bottom of the trench
between the rubber-band and an iron plate X" with exactly the same speed as
that at which the machine advances. By means of the rod a resting in the
, movable eye and provided with a wheel c the lower driver is able to straighten
the tiles which might possibly lie obliquely in the trench.
The gearing for the forward movement and steering mechanism is arranged as
follows:-
:-
The worm X (shewn in Figures 7 and 8) is keyed on the shaft T and drives the
worm-wheel Y. Between the spokes of the worm-wheel Y are two bevel-wheels ?
which work loose on the pins 9 and are in gear with the bevel wheels r and 1.
7" 15

page_text: keyed onto the shaft t, while s is loose on the same shaft, but is in one piece with
the sprocket-wheel u which by the chain a drives the main wheel A' on the left,
hand side of the machine, while the main wheel on the right hand side of the;
machine is driven from the sprocket-wheel v, which by the clutch y can be coupled
to the shaft t.
The steering is effected in the following manner.
The cords a and b shewn in Figures 12 and 13 are operated by the hand lever O.
The cord a² passes from the hand lever O over the guide-sheaves c and d² down to
the sheave e which is fastened to the frame. This frame is held in position
by the spur-pinion (Figure 11) working between the tooth-racks j fastened to
the frame Band 4 fastened to the frame C. From the guide-sheave e² the cord a²
passes now up and over the guide sheave which is fastened to the frame B
and from thence down to the guide sheave y fastened to the frame B. From
the latter guide sheave it passes over a guide sheave on the frame A and from.
thence to the shifting lever n (Figure 5). The cord 6 passes in exactly the.
same manner over guide-sheaves to the lever 1. The sheaves are arranged in'
this manner in order to always hold the cords equally tight when the frame C is.
raised and lowered inside the frame B.
↓
The lever n being thus connected with the hand-lever O by the cords a²i
and can thereby easily be operated by the upper driver by simply moving the
hand-lever O in one or the other direction.
On the shaft to which lever 12 n2 is fastened a shifting lever o³ is also fastened
as shown in Figure 8. This shifting lever being placed between the clutches p²
and it will be seen that by a slight movement of the shifting lever o in one or
the other direction the clutches will disengage.
The clutch p² being provided with feathers, which fit inside the sprocket wheel u.
both will revolve together, but if 2 was made to stop, u would also have to stop
whereby the bevel-wheel p would roll on s and consequently drive the bevel wheel
and thereby also the shaft t and sprocket-wheel faster. As now the sprocket-
wheel drives the left hand main wheel and drives the right hand main-wheel
it will be understood that the machine in this case would turn to the left. If on
the other hand the shaft and thereby the sprocket-wheel was stopped, while u
was released, the machine would then turn to the right.
This stopping of the right hand or left hand sprocket-wheel is effected by
ordinary plate-friction brakes in which every alternate plate is fitted on the
clutches and with key-ways for each feather on the same clutches, while the
other plates are fitted inside the sleeves 2 and 2 which are also provided with
two feathers on each sleeve and key-ways in the plates. In order to prevent
these sleeves from revolving they are further provided with projections which fit
in openings cut out of the stationary shield-plate t². The spiral-springs on the
back of the clutches are for the purpose of bringing the clutches together as soon
as they are released from the pressure of the shifting lever on their front side
whereby the machine will go straight ahead. If now the clutch p² is pushed back
by the shifting lever, the clutches will first disengage and, being pushed still further
back, the plates on the clutch will press against the friction-plates between them,
whereby the clutch p² will be prevented from revolving and the machine will turn,
to the left as before explained. If, on the other hand the shifting lever pushes'
the clutch back the clutches will again first disengage and by pushing g' still
further back, the plates on this clutch will press against the friction-plates which-
are held by the sleeve s², whereby the clutch will be brought to a stand-still,
and as the latter is connected with the shaft t by the intermediate sleeve u², the
shaft t will consequently be stopped and the machine will turn to the right.
The hand-lever m² with the connecting rod (Figures 5 and 8) shifting lever Z
and clutch Y is for the purpose of disengaging the gearing so as to be able to
haul the machine by horses from one field to another.

The machine may derive its motion, for example, from a travelling steam-engine
through rope-transinission.
