IMPR'ovEMENT IN AuGERs. v

The Schedule referred to in these Letters Patent and making part of the lame.

To all 'whom it may concern:

Be it known that I, WILLIAM A. 1vns, of New Haven, in the county of New Haven and State o Connecticut, have invented a.y new Improvement in Angers; and 1 do hereby deelare the following, when taken in,'counection with the accompanying drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of' this speciiieation, and represents in- Figure 1, a.V side view of the cutting-end of the auger, lookingrtoward the edge of one ot' the cutters, and, in

Figure 2, an end view of the anger.

l'This invention relates Vto an improvement in auger` bits, the object being to combine a Curved gouge Hoor-lip with a vertical cutter upon its extreme endv A is the twist of a common auger; B, the screw-point; C, the floor-lip upon one side; and C', a corresponding iioor-lip uponthe opposite side. These floor-lips are curved up from the center,

gouge-shaped, so that thecut commences at the een'- ter, working outward, thus dispensing with the use of the spur-cutters.

vspeetively, from-the tloor-lipsaty their ext-renie ends, and the said 'I-coinhine with these gouge-shaped door-lips, re-

a. perpendicular. or side cutter, a, rising gouge-shaped door-lips are curved upon the edge, seen in fig. 2.

These, so soon as the iloor-eutters have entered 'the wood, serve to trim o and gather the chips, and

prevent the binding or clogging of the cutters, whereby the .auger works mueh easier than the gongeJiu.'

, as vheretofore constructed;

- I do not wish to be understood as broadly'elaiming .a gouge-lip auger, as such, I am aware, is not new;

but I What I do claim as my invent-ion, and desire'to secure by Letters Patent, isf- 'y I n auger-bits, the Combination-of the curved edge.

gouge-shaped door-lipsOG', with'their respective side or vertical cutters a n, -connected andl arranged substantially as shown and described.
