PROVISIONAL SPECIFICATION.
Improvements in Machinery for Boring Wells and for other
Analogous Purposes.
I, JOHN HUGHES, Junior, of 19 Canterbury Road, Whitstable, in the County of
Kent, Builder and Well-borer, do hereby declare the nature of this Invention to
be as follows:
This Invention relates to improvements in machinery for boring wells and for
other analogous purposes.
According to the method of well boring at present employed, it is usual to bore
with an augur and solid rods, pulling these up every time the augur is full, which
process involves considerable loss of time. At the first obstacle encountered a
tube is driven down, and the work proceeds again inside this tube, thus
necessitating the employment of a reduced sized augur.
Now according to this Invention I dispense with the solid rods and the augur,
and effect the boring by means of tubes, as follows:-
I make a drill of a peculiar form hereinafter referred to and fix it by means of
a diminishing tube to the tube which constitutes the borer. Into the said tube I
insert loosely another tube, to receive the material as it is bored out the drill
being so made that the material can pass through it into the said inner tube.
By this construction it is only necessary to withdraw the aforesaid inner tube
when full, by means of a wire rope or otherwise, and a second tube can be inserted
whilst the first is being emptied. The top of the aforesaid inner tube is weighted
to insure its resting firmly on the top of the drill, and the bottom is provided with
the ordinary or other suitable means for keeping the material bored out in the
tube when being drawn up.
I prefer to have the outer tube of the same diameter throughout (not telescopic)
and to join the lengths of tube together by collars, thus forming a tight joint and
preventing the liability of contamination from outside from surface water or
sewage.
It is not proposed to draw up the outside tube at all, the drill being intended
to penetrate any obstacle that it may encounter.
I have annexed a drawing to this Specification, illustrating the peculiar form of
drill above referred to.
On the drawing Figure 1 shews a plan of the drill from above, Fig. 2 elevation,
and Fig. 3. plan from below.
It will be seen that space is left between the arms of the drill for the material
bored out to pass up into the inner tube.
a shews the arms of the drill of which three are represented, but I do not wish
to limit myself to this number. b are extension pieces, to which the aforesaid
diminishing tube is bolted. c are shoulders, on which the aforesaid inner tube

d is the point of the drill, e is another point inside the drill, to break any
flints upon, in the event of their entering the drill.

Improvements in Machinery for Boring Wells and for other
Analogous Purposes.
I, JOHN HUGHES, Junior, of 52 (formerly 19) Canterbury Road, Whitstable, in
the County of Kent, Well-borer, 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:-
According to the method of well-boring at present employed, it is usual to bore
with an augur and solid rods, pulling up these every time the augur is full, which
process involves considerable loss of time. At the first obstacle encountered a
tube is driven down, and the work proceeds again inside this tube, thus
necessitating the employment of a reduced sized augur.
Now according to this Invention I dispense with the solid rods and the augur,
and effect the boring by means of tubes, as follows:-
I make a drill of peculiar form, hereinafter referred to, and fix it by means of
a diminishing tube to the tube which constitutes the borer. Into the said tube I
insert loosely another tube to receive the material as it is bored out, the drill
being so made that the material can pass through it into the said inner tube.
By this construction it is only necessary to withdraw the aforesaid inner tube
when full, by means of a wire rope or otherwise, and a second tube may be inserted
whilst the first is being emptied. The top of the aforesaid inner tube is weighted
to insure its resting firmly on the top of the drill, and the bottom is provided with
the ordinary or suitable means for keeping the material which has been bored
out in the tube when it is being drawn up.
I prefer to have the outer tube of the same diameter throughout (not telescopic)
and to join the lengths of tube together by collars, thus forming a tight joint and
preventing the liability of contamination from the outside from surface water or
sewage.
It is not proposed to draw up the outside tube at all, the drill being intended
to penetrate any obstacle that it may encounter.
And in order that my said Invention may be more fully understood, I will now
proceed to describe the same with reference to the drawings accompanying this
Specification in which Fig. 1 shews a vertical section of drill and tubes as they
would appear in the process of boring, Fig. 2 shews a plan of the drill, Fig. 3
elevation of drill.
The same letters of reference are employed to denote the same parts in all the
views.
a shews drill fixed by means of the diminishing tube b to the tube c, constituting
the borer. Into the tube c I insert loosely another tube d, weighted at its top e.
This tube receives the material as it is bored out, the drill being made with open-
ings h so that the material may pass up into it.
The bottom of the tube d is provided with leaves, (three or more) preferably made

page_text: of spring steel, or with other suitable means for keeping the material bored out in
the tube d, as this latter is being drawn up.
m shews the leaves, fitting into pockets n fixed or formed on the inner surface of
the tube d. By this construction, in the event of any of the leaves m becoming
broken or worn out, it can easily be replaced by sliding a fresh one into the
pocket n. g is a point inside the drill, upon which to break flints, etc.
I may fit a diamond or diamonds on the drill, when it is required to be used for
boring through extra hard material.
The diminishing tube 6 is secured to the drill a by screwing it on, and also by the
rivets i, all shewn at Fig. 1, and to the outer tube c by means of rivets-not shewn
on the drawing.
The action of the apparatus is as follows:
-
The boring is commenced in the ordinary way, and when the first length of
tube c has been inserted into the ground another length is screwed on in the usual
way and the operation is continued until the required depth is reached, the
material bored out passing up through the holes h into the inner tube d, which
latter is raised from time to time by means of the rope or chain k, and an empty
tube d dropped into its place, this latter being lowered and kept down on the
shoulder in the drill a by means of the weight e.
For horizontal boring, suitable means would be employed such as rods controlled
by a screw, to keep the inner tube pressed against the drill whilst the boring is
proceeding.
By the use of this apparatus, borings may be effected more rapidly, economically
and efficiently than at present, as it occupies much less time to raise the inner
tube d to the surface than to disconnect the various lengths of rods carrying the
augurs, at present employed, further the boring has the great advantage of being
the same size throughout, as the drill is not changed, and separate lining tubes
have not to be employed.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. Machinery for boring wells and for other analogous purposes, constructed
and operated, substantially as set forth.
2. In boring machinery, the employment of a drill, provided with apertures in
combination with an inner removable tube, all for the purposes set forth.
3. In boring machinery the employment of an inner removable tube for the
purpose set forth.
4. In boring machinery the employment of an inner removable tube, provided
with leaves and pockets, such as those shewn at m and n respectively on the accom-
panying drawings, substantially as and for the purposes set forth.
