blade, but this is ineffectual in mixing the mud, because of its failure to agitate and stir the mud on account of its very smoothness.
The chief function of my present invention is to overcome this objection, and it consists in a bit having laterally-extending projections which will keep the mud and material thoroughly mixed and agitated,enabling the bailer's to remove all the mud, since it is thoroughly mixed and is not allowed to set tie in the bottom of the hole.
Frequently it happens that the threaded pin on the bit will break off, or become an screwed from the drill stem. In the usual style of bit-s, the blade is so heavy that it cannot be made-of any great length, and it falls sidewise in the hole, and especially is it true in the fifteen inch and larger holes. In the event of such an accident occurring, it is frequently impossible to'iish the bitout of the hole. 1
Another object of mypresent invention is to obviate this difiiculty, and it comprises a hit of much greater length for the same weight, and the lugs or projections on the side keeping the bit in an upright position in the hole, thus making it comparatively easy toobtain a hold on the top of the bit with tools made for the purpose, whereby to remove the broken bit from the hole.
In the accompanying drawings:
Figs. 1 and 2 are views ofone form of the bit in side elevation and at right-angles to each other; I p
Fig. 3'is a bottom plan view;
Figs. 4- and 5 are views of slightly modified forms of the bit. I
Referring'to Figs. 1, 2 and 3, A represents the stem of the bit; and 1 is the cutting end, it preferably having recesses 52 on opposite sides spread and beveled or sharpened at the cutting edge; At the opposite end, it has the usual pin 3, which is threaded to screw to the tool next above.
At intervals and alternately extending at right-angles to each other are the lugs 01'' projections 4, of which there are fourshown in the construction illustrated in Figs. 1 and 2. In Fig. 4 there are three lugs or projections 4 two of which extend parallel, and the third or uppermost one at right-angles thereto. g
In Fig, 5, there are two'of these lugs or projections 4- and these extend at rightangles to each other. This simply illustrates the fact that the number of lugs or projections and their arrangement about the stem or shank may vary according to the requirements.
' In this manner I have provided a bit which stirs and agitates the mud, andwhich is centered, so to speak. in the hole formed.
Other changesmight bemade in the form and arrangement described without depart' ure from the'invention.
I claim: I
1. A cable tool drill bit having a cutting end, a shank integral with said cutting end and extending upwardly therefrom, a pair oflugs extending laterally in opposite direc- .tions from said shank and integral therewith, and asecond pair of integral lugs extending laterally in opposite directions from said shank and in a difierent horizontal plane from the first pair and extending at an angle to said first pair of lugs for holding the shank in spaced apart relation from the walls of the drilled opening, each pair of said lugs being arranged in longitudinal alignment with each other, and the length thereof being substantially coextensive with the length ofgthe cutting end.
2. A cable tool drill bit having a cutting end, a shank integral with said cutting end and extending upwardly therefrom, and a pluralityof pairs of lugs arranged in different horizontal planes on the shanlgeach pair of said lugs extending at an angleto another pair, each of said pairs of lugsextendin laterally in'opposlte directions from said shank and integral therewitlnand arbeing substantially coextensive with the,
length of the cutting end.
In testimony whereof I aflix my signature.
