blocks S and S' form the said nuts, and the
block S' is rigidly mounted, whereas the block
S is movable. A screw, T, having a right and
left thread, works in the blocks or half-nuts
5 S S', said threads bearing, respectively, in said
nuts, whereby upon turning said screw the
block S can be moved toward or from the block
S', and as the sleeve R is held upon said block
S' the sleeve R will move with the block S to-
o0 ward or from the corresponding wheel 0. Two
hook-latches, V, are pivoted to the sides of
the frame and hang downward, and springs
V' press the upper ends outward, thereby
pressing the lower ends inward, so that if the
15 platform G is moved upward it automatic-
ally catches on the said latches and is locked
in position. Each leg B is provided with a
longitudinal aperture in its lower end, and in
the said aperture a toothed bar, W, is held,
20 on the lower end of which a triangular or other
foot, W', is formed. A latch, U, is pivoted
to the side of the stock, and is provided with
a prong adapted to engage with the teeth of
the rack W, and thus lock the rack in posi-
25 tion. The rack W can be released from the
catchU, and can be projected a greater or less
distance from the lower end of the leg, thus
permitting of leveling the machine and hold-
ing it any suitable distance above the ground.
30 The operation is as follows: The bit-stock is
passed through the apertured cross - bar E',
uniting the bars E, and the upper end of the
stock-bar is held in the U-shaped clip II. If
the shaft A is revolved, the bevel cog-wheel C
35 and the pinion D are also revolved, and revolve
the squared shaft D' and the bars E, which in
turn revolve the cog-wheel F and the stock,
causing the bit or scoop to form a hole in the
ground; but it is necessary to press the frame G
40 downward continually, as the wheelF,in which
the upper end of the stock is held, is mounted
on the said frame or platform. This is ac-
complished by means of the screw-spindles L,
which are revolved from the.cog-wheel F by
45 the cog-wheels K. The nut-sections S and S'
are clamped together, so that if the screw-
spindles L are revolved from the bars E they
will revolve in such a manner as to move the
platform G downward gradually, and at a rate
50 of speed proportionate to the speed of the
auger bit or scoop. If it is desired to raise
the platform G and withdraw the auger from
the hole, the screw T is turned in such a man-
ner as to separate the blocks S and S', whereby
55 the nut -blocks S will be moved toward the
outer surfaces of the wheels O, and the teeth
r on the outer ends of the sleeves R will en-
gage with the teeth o on the wheels 0, and at
the same time the longitudinal ridges s, formed
6o on the inner surfaces of the sleeves I, will
pass into the grooves L' of the shafts P, thus
engaging the said sleeves R with the shafts I,
which are revolved by the beveled cog-wheels
Q, and revolving the sleeves R, which, being
55 engaged with the cog-wheels 0, revolve the
same, and the said cog-wheels move the racks
N upward, thereby raising the platform G.The shaft A, which drives the entire mech-
anism, can be revolved by hand, or by means
of any suitable motor, as may be desired. 70
Having thus described my invention, what I
claim as new, and desire to secure by Letters
Patent, is-
1. In a post-hole auger, the combination,
with the tool-guiding uprights and their re- 75
volving gearing, of the tool-carrying pinion,
with the tool-securing contrivance fastened to
its under side between said guiding-uprights,
said pinion being adapted to revolve with said
guiding - uprights, and the platform with its 8o
lowering screw or screws geared with the tool-
carrying pinion, substantially as and for the
purpose set forth.
2. In a post-hole auger, the combination,
with means for revolving the auger, of a ver- 85
tically-movable platform or partition on which
the auger is held, screw-spindles projecting up-
ward from the said platform, and nuts formed
of two sections, through which nuts the spin-
dles pass, and means for revolving the spin- 90
dles from the means of revolving the auger,
substantially as herein shown and described.
3. In a post-hole auger, the combination,
with means for revolving the auger, of a ver-
tically-movable platform or partition on which 95
the auger is held, spindles projecting upward
from the said platform, nuts through which
the spindles pass, which nuts are formed of
two sections, a screw for separating the sec-
tions or bringing them together, and means 1oo
for revolving the spindles from the means for
revolving the auger, substantially as herein
shown and described.
4. In a post-hole auger, the combination,
with means for revolving the auger, of the Io5
vertically-movable platform G, the cog-wheel
F, pivoted onil the platform G, and adapted to
hold the upper end of the auger-stock, the
cog-wheels K, engaging with the cog-wheel F,
the screw-spindles L, projecting upward from ITo
the cog-wheels K, and nuts through which the
screw-spindles pass, substantially as herein
shown and described.
5. In a post-hole auger, the combination,
with the upright bars 1, between which the r5
auger-bit is held and guided, of the vertically-
movable platform G, the cog-wheel F, pivoted
on the same, through which cog- wheel the
bars E pass, the cog-wheels CK, engaging with
the cog-wheel F, the screw - spindles L, pro- 120
jecting upward from the cog-wheels K, and
nuts through which the said spindles pass,
substantially as herein shown and described.
6. In a post-hole auger, the combination,
with the upright bars E, for holding and guid- 125
ing the auger, of means for revolving the said
bars, the beveled cog-wheel Q', through which
the bars pass, the beveled cog - wheels Q,
mounted oni the shafts P and engaging with
the beveled cog --wheel Q', the cog-wheels 0, 130
mounted loosely on the shafts P, the racks N,
engaging with the cog-wheels 0, means for re-
volving the cog - wheels O with the shafts P,
the vertically - movable platform or partition
