Improvements in Augers or Boring Tools.
We, THE SANDYCROFT FOUNDRY AND ENGINE WORKS COMPANY LIMITED
of Sandycroft, Flintshire, Manufacturers, and JOHN JONES, Foreman of Timber
Department, Sandycroft, aforesaid, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an auger more particularly adapted for boring hard
wood but applicable also for boring soft wood.
According to this invention the auger is provided with a "pod," box, or frame
at the end, which carries on its edges or exterior, adjustable and removable
cutting or marking teeth which are provided with slots therein through which
screws are passed to secure them to the frame, or such teeth may be adjustable in
other ways.
Inside the frame is a knife or cutter, or it may be two or more of same, radially set
from the centre and having an angular face which projects below or through the
frame in the manner of the knife or cutter of a plane, such knife being adjustable
and removable by means of screws or in other ways.
An auger constructed according to this invention possesses several advantages
over those at present in use, among them being its adaptability for enlarging holes
already made.
The "pod" box, or frame, described can be applied to old augers or boring tools
which have become useless from wear.

We, THE SANDYCROFT FOUNDRY AND ENGINE WORKS COMPANY LIMITED,
of Sandycroft, Flintshire, Manufacturers, and JOHN JONES, Foreman of Timber
Department, Sandycroft, aforesaid, 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:—
This invention relates to an auger more particularly adapted for boring hard
wood but applicable also for boring soft wood.
According to this invention the auger is provided with a "pod," box, or frame
at the end, which carries on its edges or exterior, adjustable and removable
cutting or marking teeth which are provided with slots therein through which
screws are passed to secure them to the frame, or such teeth may be adjustable in
other ways.

One form of auger constructed according to our invention is illustrated in the
accompanying drawing in which
Fig. 1 is an elevation of one side of same.
Fig. 2 is a plan on line x-x.
Fig. 3 is an elevation of another side of the auger and
Fig. 4 is a plan of the under or cutting face of same.
The auger shown consists of the usual helix portion a to which is attached a pod
or box 6 which may be formed in one with the portion a or be brazed or secured
thereto.
At one, two or more points on the periphery of the box b are arranged the
cutting or marking teeth c. As shown two of these are employed and they are
adjustable by means of set screws d passing through slots in same into the side of
the box but they may be simply jammed in the groove in the box and held in
that way.
In the box are two cutters e arranged at an angle like the cutter of a plane
and held to a sloping face f, cast or formed with the box, by means of screws g
which pass through slots in the upper end of the cutters so that they may be
adjusted.
The cutting edges project through slots in the under face of the box which
face has a central gimblet point i (which if the box portion b is not formed of steel)
may form part of a block of steel j let into and brazed or secured in the box or to
the bottom of the helix a if it extends so far.
An auger constructed according to this invention possesses several advantages
over those at present in use, among them being its adaptability for enlarging holes
already made.
The "pod," box, or frame, described can be applied to old augers or boring tools
which have become useless from wear.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. A pod, box or frame for augers or boring tools having an adjustable plane like
cutter and a marking tooth arranged substantially as described.
2. The improved auger or boring tool constructed substantially as described and
illustrated.
