W. L. PARMELEE. 'Auger.
No. 242,362. I Paten'ted May 31,1881.
UNITED STATES PATENT OFFICE.
WILLIAM L. PARMELEE, OF ANSONIA, CONNECTICUT.
AUGER.
SPECIFICATION forming part of Letters Patent No. 242,362, dated May 31, 1881.
' Application filed March 31, 1881. (No model.)
To all whom it may concern:
Be it known that I, IV. L. PARMELEE, a citizen of the United States,residing at Ansonia, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Angers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referent-e being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which forma part of this specification.
My invention relates to angers for boring purposes; and the novelty consists in the construction and adaptation of the same, as will be more fully hereinafter set forth, and specifically pointed out in the claim.
The object of the invention is to produce an anger which will hold itself to the cut and avoid the splittingor breaking upon the back of the board, timber, or the like, and this OhjectIaccomplish by meansof thedevice shown, and herein described.
In the ordinary and well-known anger great difficulty is experienced at the last end of the anger-hole by the loss of holding gripe, and the auger must either be forced through the material, leaving a rough and uncouth exitapertnre, or the plank be reversed and the screw entered in the hole left by the operation from the opposite side.
In carrying out the invention I employ an ordinary auger, and affix the holding-screw, of gimlet form, in the center thereof. The dupleX lips at the cutting end are soinclined inwardly that the screw will hold tenaciously until the cutting portion has entirely separated the part described by the area or sweep of the anger. Each radial lip is provided with a cutting-spur, and the incline is such that the spur will be sufficiently in advance of the larger diameter or holding portion of the screw to insure the separation of thelongitndinal fibers of the wood, while the screw exerts its proper influence.
The invention is fully illustrated in the accompanyingdrawings, which form a part of this specification, and in which- Figure 1 is a longitudinal elevation; Fig.2, an enlarged view from another point of observation. and Fig. 3 an end detail view.
Referring to the drawings, in which similar letters of reference indicate like parts in all the figures, A represents the twisted body of the auger, and (t the rectangular portion, as shown. In the longitudinal diametrical center is formed the gimlet-screw D, and the cutting-lips Bare inclined inwardly, and provided with cutting-spurs C in such a manner that the screw I) will hold until the spurs (3 have severed the. longitudinal fibers, and a clean out, without the necessity of reversing the timber, and avoiding the breaking the surrounding exit. is obtained.
1 am aware that the holding-screw and the int-hned cutting-lips are not,broadly,new with me. and that the cutting-spurs have been before used, and neitherof these devicesis sought to be covered, broadly, in this application.
The essential feature of the invention rests in the combination of the inwardly-inclined cutting-lips, the spurs C, and theholding-screw, as shown.
It will beohserved that by my construction the cutting-surfaces may readily be sharpened without changing the angle of the file and without injuring the spurs.
What 1 claim as new is- As a new article of manufacture, the augerbit herein described, consisting of the body A, rectangular portion a, the inwardly-inclined cuttinglips B, having cutting-spurs C, and the holding-screw l), the whole lorined and arranged as and for the purposes -set forth.
In testimony whereof I affix my signature in presence of two witnesses.
WILLIAM L. PARMELEE.
