Egrth-Augers.
Patented Oct. 28,1873.
UNITED STATES PATENT OFFICE.
nnASruS n. CLARK, on APPLETON, WISCONSIN.
lMPROVEME NT IN EARTH-AUGERS.
Specification forming part of Letters Patent No. 143,963, dated October 28, 1873 application filed August 1, 1873.
- To all whom it may ooncem:
ting-knives attached to the body of the auger,
so as to be taken off and replaced when neces sary; and the auger is arranged so as to have the earth which is displaced fall into the in side, and to be opened for the discharge of the same.
Figure 1 is a perspective view of my invention. Fig. 2 is a view of the auger open, and
Fig. 3 is a view of the closing-piece to close the opening between the knives.
A is the upright shaft, secured at its lower end to the cross-bar B, to which is attached at each end of it the cylinder or body of the auger G O, in two' parts, bolted to the cross-bar B by bolts D D, forming a hinge or joint, so that the'operator, by removing the key Gr, can open the body of the auger and discharge the dirt. There are two other bolts, D D, on the opposite side of the auger. E E are bail pieces, attached to the body of the auger, and crooked so as to pass across the shaft A and under pin F. G is a key, placed in shaft A and under bail pieces E E, to hold the auger together; H H are the cuttingknives, fastened to the body 0 of the auger, one on each side, constituting the bottom of the auger, and set so that as the auger is revolved they will cut the earth and fill the same. I is a piece of metal to fill up the space between the knives H, which is left open between the edge of one knife and the back of the other, so as to bore and hold sand. hen boring clay or gravel these pieces are not needed; but when boring sand, if they are not on when the auger is raised thesand would run out. K are bolts, by which the knives L L are secured to the sides of the auger. These knives L L are for thepurpose of enlarging the hole, so that the auger can be moved up and down in it. M M are the rimming-knives, attached to the upper edge of the body of the auger by means of bolts N, which serve as pivots .for the knives to move out and in on. These knives have slots or oblong holes, P, in them, allowing them to be moved out and in, as desired, and secured in place by bolts Q. These knives secure the enlargement of the hole beyond the size of the auger.
I claim as my invention- 1. The peculiar construction of the rimmingknives M M and themode of attaching them to the auger by means of bolt-s N N serving as pivots for the knives to turn on, and an oblong slot in the knife, through which a bolt, Q, passes to admit of setting the knife out or in. a
2. Bail pieces BE, in combination with shaft A and pin F and key G, substantially as described.
3. Cylinders G C, hinged to bar B, in combination with knives H H, substantially as described.
