" Specification of Letters Patentl ;1 t 1jd 61 ,20 19 4 a lication filed August 3, 1 9 12. seri Nb. 713,159.
To all whom it-may concern: Be it known that we, BE JAMIN VAT- KINS, a citizen of the United States, and a resident of Nehawka, in the county of Cass and State of Nebraska, and TAYLon NA r- KINS and WVALTER I. WVATKINs, citizens of.
the United States, and residents of Elizabethtown, in the county of'Hardin and State of Kentucky, have invented certain new and useful Improvements in EartlrAugers, of
which the following is a specification, refer- 'ence' being-had to the accompanying drawings.
an auger of this character having an improved construction and arrangement of dirt cutting bits whereby the Walls or sides of thehole will be cut back from the sides of the auger thereby forming a hole slightly larger than the diameter of the auger which will eliminate unnecessary friction and pre vent the accumulation of sticky soil on the outer side of the tool. 7
Another object is to provide an improved construction and arrangement ofdirt lifting blades by means of which fine dirt or sandy soil may readily be removed-from the'hole. With these and'other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described andclaimed. a
part of this specification and in which like numerals of reference indicate similar parts in the several views:Figure 1 shows a view partly in section. Fig. 2 is a front view. Fig. 3 is a side view. Fig. his a rear view thereof. Fig. 5, is a cross section! I will cut an opening larger than the diameter of the auger body. Unnecessary friction will result if this is not done.
This invention relates to certain new and In the accompanying drawings forminga- In the preferred form of our auger, we use a semi-cylindrical;body l of more than180 degrees having the straight parallel rungered position as shown in Fig. l, the bit 5" ning edges 9. The bits 'are three,.co1nbeing the lowest, the opposite bit 5 coming neXt, and the intermediate bit 15, being the I highest. These bits are arranged in spaced re- 'lation as shown-1n Fig.6. 7 In addition to being cupped, the edge bits 5 and 5 are'bowed outward beyond the surface ofthe auger body 1, as will be understood in referring to Figs. 1 and 4:,so that the hole will havea larger diameter than the auger body '1. "As shown in Fig. 5, the, bits are pointed. Thebit 5 has the outward cutting edge 7, while theopposite similar bit 5,has theinner cutting edge 7 The edge 22, of the bit, 16, however, corresponds in curvature to the cutting edge a.
The bit 5 has the straight cutting: edge, 7 I
while the opposite edge is curved. In Fig. 1,
the bow of the outwardly dishededge bits 5 v and 5 is clearly indicated. A spanner head 3 has its two ends a secured to the auger body 1, while its. boss 2 is arranged to receive the rod or pipe 3, towhich'the operating handle 4: issecured. Thisbitican be success- I fully and expeditiously employed in drilling holes, in clinging soils without'danger of the soil clinging to the body of the auger, thereby causing amnecessary friction. To-the upper end of the body 1 is secure a handlesocket 2,-which is preferably thread-.
ed interiorly and forms part of the spanner head 2, the ends of which are riveted or otherwise seeuredfto the' body as shown. Secured at its lowerend inthe socket 2, is a handle 8, on the upperendiof which is farbe readily turned in forming thehole, On
and are turned to form a scoop shaped bot-' tom or lower end for the'sa1ne;
One of the edges of the blad s 5 is turned outwardly to a slight extent and beveled to form a cutting edge 7, whereby the blades also serve as the bits of the auger. projection of the beveled cutting edges of the The ranged a cross bar 4:, whereby the auger may blades 5, 5, and 5" gradually increases from the lower ends of the blades toward their upper ends and at said upper ends of the beveled edges of the blades which adjoin the smaller blades, are circular notches 8 which facilitate the outward bending or turning of the cutting edges.
By forming the cutting edges of the blades at their upper ends, as shown and described, a hole of slightly larger diameter than the body of the auger will be formed so that the sides of the latter when turned will not engage the walls of the hole, thus eliminating all unnecessary friction and also preventingsoft sticky soil from adhering to and accumulating on the sides of the tool. As shown the cutting, edge of the central blade 5 is straight and extends obliquely to the axis of the cylindrical body 1. The dished lifting blades 6, and 6, are positioned between the central and edge cutting bits. As shown two smaller lifting.
blades are located between the bits 5 and 5, while a single cutting bit 6, is located between the cutting bits 5 and 5", these lifting bits being of successively greater length.
By providing the smaller blades 6 between the larger blades the lower end of the anger is closed to a sufficient extent to permit the scooping up and removal of fine dry dirt and sandy soil which is diificult to re: move from the holes with the usual form auger.
The purpose and manner of using augers of this character is well known and from t the foregolng descrlptlon taken in connection with the accompanying drawings, the construction and operation of our improved auger will be readily understood, without requiring a more extended explanation.
Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the what we claim is:
; principle or sacrificing any of the advantages of the invention as claimed.
Having thus describedour saidrinvention,
1. A post hole auger,"comprising a body of more than half a cylinder having a centrally positioned and two triangular edge cutting bits arranged in spaced relation each bit being dished outward beyond the circumference of said body, the cutting edge of said central bit being straight and ex tending obliquely to the axis of said body, a dished lifting blade positioned between one of said edge bits and said central cutting bit, and two smaller lifting blades between the remaining edge bit and central bit said lifting blades being of successively greater length, and a spanner head secured to the upper end of said body, as and for the purpose set forth.
2. A post hole auger comprising a body of more than half the cylinder having a centrally positioned and two triangular edge cutting bits arranged in spaced relation each bit being dished outward beyond the circumference of said body, and a dished lifting blade positioned adjacent said central cutting bit upon both sides, as and for the purpose set forth.
