of the auger and being adjustable so as to make different sizes of recesses.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. I
In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:
Figure 1 is an elevation of the improved auger.
Figure 2 is a sectional view on line 2 2 of Figure 1.
Figure 3 is a rear view. Figure 4 is a sectional view on line 4 4 of Figure 1. i
In these views, 1 indicates the shank of the auger which is formed of two parts, the
upper part carrying the socket 2 for re-.
ceiving the actuating tool. A. head 3 is provided with a rectangular bore 4: for receiving the reduced ends 5 of the two parts of the shank and with a dove-tail groove 6 on one face, which is inclinedly arranged, to receive the bit 7. A bolt 8 passes through the bit, the head and the reduced part of the upper part of the together, the bit shank to hold the parts being provided with a number of holes, for engagement by the bolt,
so that the bit is groove in the head.
shank is held in th of the head by a adjustably held in the The lower part of the e lower part of the bore pin 9. Ribs 10 are in.
clinedly arranged on the rear: part of the head, one on each side of the nut 11 on the bolt, for removing bit from the hole.
From the above device will make a of a hole made by the material cut by the it will be seen that the recess at the outer end the auger for receiving the head of a bolt or the like and said recess can be made of different sizes by adjusting the bit on the head It is thought from the foregoingdescription that the advantages andnovel features of my lnventlon will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and ar rangement of the several parts, provided. that such changes fall within the scope of the appended claim.
\Vhat I claim is An auger of the class described having a head connected with its shank inclinedly ar ranged ribs on one face of the head, abit inclinedly arranged on the other face of the head and means for adjustablyholdingthe bit on the head.
