TOOL COMPANY, OF ERIE, PENNSYLVANIA, .A CORPORA'IION 01E PENNSYLVANIA.
To all whom it may concern:
Be it known that I, CLINTON E. WILDER, a
citizen of the United States, residing. at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Core-Drills; 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 sa1ne,reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.
My invention relates to core drills, and consists in the improvements hereinafter described and pointed out, and illustrated M in the accompanying drawings, in which 2-- I ting tool D, by means of screws d, which n Figure 1, is a side view in elevation of a core drill embodying my invention. Fig. 2, 1s a transverse section of the same on the line a:m in Figs. 1 and 3. Flg. 3, 1s a side elevation of the same looking in the direc tion of the arrow in Fig. 1. n
In these drawings A, indicates a tapered shank of the drill; A, indicates the tang on the upper end thereof, which are common in the construction of drills. From the lower end of the shank A, the stock B, of the drill slot having fiat radial surfaces 0. Upon one of these flat radial surfaces 0, I secure a cutpass through slotted openings d, in said tool- I The rear surface of the tool D, pref-. erably at its upper end, is provided with transverseteeth or serrations (P, which engage like teeth n, on the flat radial surface 0,
on the side of the slot C.
Specification of Letters Patent.
oceans-inn.
Patented July 6, 1915.
Application filed August 4,1914. Serial No. 854.966.
In Fig. 2, I illustrate a longitudinal rib 03 on the back of the tool D,which fits into assists in holding the tool D, in its proper position.
In operation, when it is desired to take a sample of the metal of a forging, from which it is desired to make a shaft or other article of manufacture, the tool B, prescribes an annular cut into the body of the forging,
such distance as may be desired, leaving a.
core or plug of metal, which enters the longitudinal opening C, in the drill, until the desired depth has been cut, when said core orplug can be broken out and removed for the purpose for which it is desired. As the cutting edge of the tool D, is worn away, the
screws cl, may be loosened and the tool moved downward slightly, and again firmly secured in place with the teeth (Z2, and 6,
shown in Fig. 3, held firmly in mesh by the screws (Z. I
Having thus fully described my invention so as to enable others to construct the same, what I claim as new and desire to secure by Letters Patent, is j In a deviceof the'character described, a cylindrical. stock having a central longitudinal recess therein, and a longitudinal slotted opening through the wall of said stock having radial side surfaces therein,
said slotted opening being substantially coextensive in length with said central recess, a cutting tool adjustably secured upon one of said radial walls and having its cutting edge projecting slightly beyond the lower end of said stock, a shank integral with said stock and means on said shank toprevent said shank and stock from rotating with relation to its operating mechanism, substantially as described.
In testimony whereof I affix my signature,
in presence of two witnesses.
