JOHN E. MILES, OF MARLIN, TEXAS.
POST-AUG ER.
SPECIFICATION forming part of Letters Patent No. 293,490, dated February 12, 1884.
Application filed November 6, 1883. (No model.)
lo all wholm it may concer:
Be it known that I, JoHN E. MILES, a citi-
zen of the United States, and a resident of
Marlin, in the county of Falls and State of
.5 Texas, have invented certain new and useful
Improvements in Post-Augers; and I do here-
by declarethatthefollowingis a full, clear, and
exact description of the invention, which will
enable others skilled in the art to which it ap-
io pertains to make and use the same, reference
being had to the accompanying drawings,
which form a part of this specification, and in
which-
Figure 1 is a perspective view of my im-
15 proved post-auger. Fig. 2 is a similar view
of the expander-disk on an enlarged scale;
and Fig. 3 is a longitudinal sectional view of
the entire apparatus.
Similar letters of reference indicate corre-
20 sponding parts in all the figures.
My invention has relation to post-augers or
post-hole diggers; and it consists in a certain
improvement upon the post-auger for which.
Letters Patent of the United States No. 283,010
25 were granted to me on the 14th day of Au-
gust, 1883, the nature of which said improve-
ment will be hereinafter more fully described
and claimed.
In the accompanying drawings, the letter A
30 indicates the shaft, having the removable
cross-handle B upon its upper end, and hav-
ing a block, C, fastened upon its lower end,
which block has a number of recesses or sock-
ets, D, for the insertion of the auger-blades
35 G, which are held in place removably in their
respective sockets or recesses by means of set-
screws F. Fastened to and extending down-
wardly from the lower end of the socketed
block C is a screw-threaded rod, H, which is
40 inserted through the central aperture, J, of
the expander-disk I, which is held in place
adjustably upon the threaded rod H by means
of the nuts K and L. This expander-disk I
has wings or extensions M, corresponding in
45 number and arrangement to the auger-blades
G, each wing being provided with the bev-
eled slot N, through which the appropriate
blade is inserted. It follows that by adjust-
ing disk I up or down by means of its nuts
50 K L the blades may be expanded according
to the diameter of the hole which it is desired
to bore; and it will further be seen that disk
I, with its slotted wings or projections M,
serves to brace the auger-blades and to hold
the same the proper distance apart and in 55
their proper relative position to one another.
The disk I also serves to raise the dirt bored'
or cut loose by the blades, by causing it to be-
come compacted or packed against the disk,
holding it fast until raised out by the with- 60o
drawing of the implement from the post-hole.
It will also be seen that by properly adjust-
ing the expander-disk the lower pointed ends,
i, of the auger-blades may be so arranged as
to cross one another, thereby forming a per- 65
feet auger-bit, which will penetrate even the
hardest soil easily, without danger of break-
ing the points of the blades, as they mutually
re-enforce one another.
Having thus described my invention, I claim 70
and desire to secure by Letters Patent of the
United States-
1. The combination, in a post-auger, of the
socketed block, the screw-threaded rod ex-
tending from the center of the lower end of 75
the block, the expander-disk'fitting upon said
threaded rod, and having the slotted wings
or extensions, the two nuts for adjusting the
position of the expander - disk upon the
threaded rod, and the curved auger-blades, 80
as and for the purpose shown and set forth.
2. The herein-described post-auger, con-
sisting of the shaft, the cross-handle, the sock-
eted block, the curved auger-blades, the set-
screws securing the blades in their sockets, 85
the screw-threaded rod extending from the
center of the lower end of the block, the ex-
panddr-disk having slotted wings or exten-
sions, and the two nuts for adjusting said disk
upon the threaded rod, as and for the pur- go90
pose shown and set forth.
3. In a post-auger, the combination of the
curved concavo-convex auger-blades and the
adjustable slotted expander-disk, whereby
the lower pointed ends of the blades may be 95
arranged to cross one another, as and for the
purpose shown and set forth.
In testimony that I claim the foregoing as
my own I have hereunto affixed my signature
in presence of two witnesses.
JOHN E. MILES.
