PATENT OFFICE.JAMES DOBBS. SANFORD, OF LOMETA, TEXAS.
POST-AUGER.
SPECIFICATION forming part of Letters Patent No. 727,847, dated May 12, 1903.
Application filed June 14, 1902. Serial No. 111,604. (No model.)To all whom it macy concern:
Be it known that I, JAMES DOBBS SANFORD,
a citizen of the United States, residing at
Lometa, in the county of Lampasas and State
5 of Texas, have invented certain new and use-
ful Improvements in Post-Augers, of which
the following is a specification.
This invention relates to post-augers, and
has for its object to provide a device of the
-zo class described which will possess points of
advantage in convenience, simplicity, inex-
pensiveness, effectiveness, and .general effi-
ciency.
Another object of the invention is to pro-
15 vide a device of the class described which can
be operated with ease in a hard or difficult
soil, such as is found where the land is stiff
or in hard-trodden trails.
Another object of the invention is to pro-
2o vide a device of the class described in which
the edges of the cutting-blades incline around
each other, so as to cause the dirt removed
in the operation of the auger to pass to the
inside or toward the center of said blades.
25 Another object of the invention is to pro-
vide a device of the class described which is
provided with plates having substantially
parallel vertical sides and curved in conform-
ity with the upper portion of the cutting-
30 blades and which form a pocket to receive
the dirt removed by the cutting-blades.
Another object of the invention is to pro-
vide a device of the class described in which
the blades are arranged at the lower end of a
35 pair of tongs one of whose shanks is provided
at its upper end with a handle having means
for locking the other shank when the device
is in operative position and in which the cut-
ting-blades are provided with an interlock-
40 ing portion which cooperates with the handle-
lock in preventing the blades being pressed
apart when operating the device.
Another object of the invention is to pro-
vide a device of the class described in which
45 the blades are arranged at the lower end of a
pair of tongs, so that when a certain portion
of dirt has been cut away the device may be.
withdrawn from the hole and the tongs
opened, permitting the dirt to fall in the re-
50 quired spot.
In the drawings, Figure 1 is a side eleva-
tion of a post-auger embodying my improve-inents and showing the same in inoperative
position in broken lines. Fig. 2 is a sectional
view on the line x x, Fig. 1. Fig. 3 is a de- 55
tail view of the stop, showing parts broken
away and parts in section.
Corresponding parts in all the figures are
denoted by the same reference characters.
Referring to the drawings, 1 designates a 6o
pair of tongs having shanks 2, pivoted inter-
mediately of their length and of which the
lower parts are bent apart below the 'pivotal
point and then extended parallel to each
other and then inclined toward each other, so 65
that the inclined portion when the device is
in operative position forms a triangle. - A
handle 3 is secured at the top of one of the
shanks 2 in any suitable manner, herein
shown as by forming an eye 21 at the top of 70
the shank 2. and inserting the -handle 3
through such eye and securing it therein by
a rivet 3a, passing transversely through the
walls of the eye 22. The organization of the
parts is such that when the tongs are closed 75
the upper end of the handleless shank 2 will
slide along the side: of the handle 3, and
means are provided to lock the upper portion
of such handleless shank 2 in closed posi-
tion. Such means are here shown as a stop 8o
3b let' into the handle 3 and having an in-
clined upper surface and a slight vertical
shoulder-rising above the handle 3 at the end
toward the eye 21.
Each shank 2 is provided at its lower ends 85
with means for cutting holes in the earth to
receive fence-posts, telephone or telegraph
poles, and similar objects and to convey the
earth cut away in making such holes into the
interior of such means and between the lower 90
ends of the shanks 2. Such means in the form
herein shown consists of cutters 4, having
straight cutting edges and respectively se-
cured angularly of each other when the auger
is in operative form on the inclined lower por- 95
tion 2b of the shanks 2, which cutters 4 are sub-
stantiallytriangular'with a rather blunt apex
and curved so that they together form'a sub-
stantially cone-shaped cutting member at the
lower end of the tongs 1 when the same are too
closed, and the opposite end of each of said
cutters 4 overlaps the adjacent edge of the
corresponding cutter 4, the space between
the overlapping edges being varied in width,
