PROVISIONAL SPECIFICATION
Improvements in the Method of and Means for Making and Laying
Pipe for Irrigating or Draining Land.
PEROT RICHARD JULIUS WILLIS, of 55 Chancery Lane, in the Conaty of
London, Manager, do hereby declare the nature of this invention (a communication
to me from abroad by Robert F. Dockery, of Los Angeles, Cal., U.S.A,
Gentleman,) to be as follows
This invention relates to improvements in the method of and means for irrigating
o draining land, and it consists in simultaneously making continuous pipe and
laying it in ditches or upon land for the purposes aforementioned.
The invention comprises a machine consisting of a cylinder or tube, which may
be closed at one end and open at the other and tapering to a larger diameter at
the open end. A shaft passes through the cylinder, and extends about half-way
the length thereof, where its end is secured (but capable of longitudinal movement)
to a worm or screw adapted to revolve in close contact with the inner surface of
the cylinder, and having a forwardly projecting piece, of round section, which
forms a core for the pipe. A boppor is situated above the worm upon the cylinder.
At the rear of the worm is a piston pressed by a spring coiled around the shaft.
The rear end of the cylinder is supported by a wheel adapted to run upon the
ground. The shaft in the cylinder is rotated by bevel-gear and crank-handles
connected therewith by a vertical shaft journalled in stable supports. Suitable
handles are secured to the supports by means of which pro-sue may be applied to
the machine.
In operation, clay oi cement is inserted in the hopper and the woim or screw
being rotated, the substance is ejected from the month of the cylinder around the
core which it leaves in the form of pipe; the machine moving rearwardly as the
pipe lengthens, owing to the backward pressure on the worm or screw
The pipe may be of one continuous length or be severed into lengths as
desued.
The spring-pressed piston serves to regulate the pressure on the worm or scrow
by reason of differences in the consistance of the substance used, or owing to the
egular motion of the machine, which may be caused by uneven ground; thus
ensuring eveness in the density of the pipe. The density cau also be iegulated by
pressure being applied to the handles upon the supports aforementioned, thus
causing the machine to travel moro slowly
By this means, a continuous length of pipe may be laid beneath or upon the
ground and may, for irrigating purposes, be perforated whilst soft for the escape
of water supplied from a stand-pipe or other source.

1, PEROY RICHARD JULIUS WILLIS, of 55 Chancery Lane, in the County of
London, Manager, do hereby declare the nature of this invention (a communication
to me from abroad by Robert F. Dockery, of Los Angeles, Cal, US.A,
Gentleman,) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement
This invention relates to an improvement in the method of making and laying
pipes for rigating or dramming land and in that class of pipe making machines
which are adapted to form tiling and the like of plastic material such as clay,
and it has for its principal object to provide a machine where it will be possible
to regulate with greater efficacy the density of the pipe formed. This end attain
by providing a machine which will move as the pipe is formed, owing to the
reaction on the machine and providing means for etarding the movements of the
machine, thereby compressing or increasing the density of the pipe.
In the accompanying drawings.-Fig I represents a longitudinal section of the
complete machine. Fig. 2 is a front elovation thereof.
The reference numeral 1, indicates a longitudinal cylinder formed of metal
and having one end closed by the angle casting 2, while the remaining or rear
end is left open as shewn. This open end of the cylinder is slightly larger than
the opposite end, owing to the result of a gradual taper in the cylinder from the
front to the rear end. The upper side of the cylinder 1, at about its middle is
formed with an opening over which the hopper 3 is secured, such hopper being formed
flaring or bell shaped as usual and adapted for the reception of the material of
which the pipe is formed.
4 indicates a shaft which extends longitudinally in the cylinder 1, and which is
revolubly jourualled in the box 5, of the angle casting 2, and the partition 6,
fixed the cylinder and just for ward of the hopper 3. The rear end of the
shaft 4 extends beyond the partition 6 and 18 there securely connected to the worm
or screw 7, which is fitted snugly within the cylinder so that the threads thereof
will engage with the interior sides of the cylinder.
Formed integral with or rigidly secured to the rear end of the worm or screw 7,
18 the core 8, which is axially coincident to the worm and to the cylinder which
projects a short distance beyond the latter. The forward end of the shaft 4 18
provided with a mitre gear 9, bevelled rearwardly, aud fixed to the shaft so as to
impart movement thereto. This gear 9 meshes with a companion gear 10, fixed in
turn to the lower end of the vertical shaft 11 which has its bearings in the
horizontal portion of the casting 2, and in the horizontal plate 12, of the vertical
frame bars 13.
The frame bars 13 are two in number and are bolted one to each side of the
casting 2 and project vertically therefrom, diverging or spreading slightly as they
proceed.
14 indicates a hand grasp which 18 rigidly secured to the contracted upper ends
of the bars 13, and which is provided to permit the manipulation of the machine
as will appear more fully hereinafter. Formed integral with the bars 13, and near
the upper ends thereof, are the boxes 15, which are horizontally aligned and which
are provided to afford the shaft 16 a bearing. This shaft 16 is projected slightly
beyond the bars 13, and is provided at its projected ends with the oppositely
arranged crank arms 17, provided with handles 18, and adapted to furnish means
for unparting to the shaft 16, a rotary movement.

page_text: The upper end of the shaft 11, is projected slightly above the bar 12, and is
provided at such end with the bevelled gear 19, meshing with the similar though
smaller gear 20, affixed to the shaft 16 By this means inotion is transferred from
the shaft 16 to the shaft 11, and thence through the medium of gears 9
and 10 to the shaft 4, all of which will ho made the subject of subsequent
explanation.
21 indicates two braces, which extend downwardly and rearwardly which aro
bolted or other wise rigidly secured to the respective bars 13, and to the respective
sides of the cylinder 1. The purpose of these braces is to brace the bars 13, as
will be understood.
Formed integral with the front side of the casting 2, and projecting forward
therefrom nie the brackets or lugs 22 which are two in number and are provided
to form means for resolubly mounting the carrying wheel 23, whereby the front
end of the cylinder is raised from contact with the ground and provided with a
rolling support. The casting 2 is formed at its vertical portion with a circular or
disc like part as will be seen in Fig. 2 whereby to close the front end of the
cylinder 1, and this is effected by placing said disc like portion within the front
end of the cylinder and securing it in place by suitable means.
In the use of my invention supposing that it is desued to form and lay tiles in
a ditch, all that will be required will be to fill the hopper 3, with the clay or
whatever material may be used, and lay the machine longitudinally within the
ditch Tho cranks 17 should now be tuined which will cause the shafts 16, 11,
and 4 to revolve owing to their respective and several gears while the movement
of shaft 4 will be directly imparted to the woim 7 and cone 8, whereupon the clay
from the hopper 3 will be caused to enter the cylinder and owing to the operation
of the worm be ejected from the rear aud flaring end of the cylinder. During
this operation the core 8 will be operating to shape the clay into the form of tiling
or pipe as will be understood.
As the tiling 18 ejected from the cylinder 1, the continual force attending and
causing its ejection will react directly upon the woim 7 and indirectly on the whole
machine and cause the same to move forwardly.
This movement 18 continuous during the ejection of the pipe; and thus tho
machine operates Supposing, now, that it be desired to increase the density of
the pipe, as it is delivered, all that will be necessary is to apply downward pressuro
to the machine and to facilitate this, I provide the bars 13, and the attending
framework, whereby the said power may be applied. The band grasp 14 furnishes
means for this application of power and for this purpose it was provided. As the
machine is pressed down its movement will be retarded thus causing more power
to move it, and before this power can be applied the pipe being formed must have
more rigidity, which is given it by Dorcasing the density of its material. When
this rigidity is attained the proper rigidity will also exist and the forward movement
of the machine will be again resumed.
It will be observed that the machine is capable of use in places other than in
ditches, and that it may be made to form pipes for use in trade. When no
operating however it will bo necessary to divide the pipe. This may be done
by any preferred and suitable means, since it does not enter into my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim 1s:-
(1) The herein described method of making and laying pipe for irrigating or
draining land substantially as described.
(2.) In a machine for making pipe, the combination of a cylinder provided with
a hopper at its upper side and communicating with its interior, a worm arranged
within the cylinder and below the hopper, a core within the cylinder and connected
axially with one end of the worm, a shaft fixed to the other end of the worm and
mounted centrally within the cylinder, a second shaft perpendicular to the first

page_text: and geared therewith, a frame rigid on the cylinder and projecting parallel with
the second shaft within which the said shaft is jourualled, the frame having a hund
grasp thereon, and a crank shaft mounted in the frame and geared with the second
shaft substantially as described.
(3) In a machine for making pipe, the combination of a cylinder having a feed
opening, an angle casting at one end thereof, said casting having a disc like
portion fitting in and closing one end of the cylinder, a carrying wheel revolubly
mounted at the outer side of the disc like portion, a shaft extending centrally in
the cylinder and journalled revolubly therein, a worm within the cylinder and
fixed to the shaft, a core fixed iu turn to the worm, two bais rigidly fixed to
