SPECIFICATION forming part of Letters Patent No. 4632507, dated November 1'?, 1891.

Application led January/*29, 1891. Serial No. 379,53 9. .(No model.) I

To @ZZ whom, t may concern:

Be it known that we, ALBERT D. GOODELL and HENRY E. GooDELL, citizens of the United States, residing at Shelburne Falls, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Drilling-Tools; and we do hereby declare the following to beafull, clear and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our present invention relates to certain improvements in tools for drilling holes in wood and other materials of a like nature by the exertion of pressure repeatedly upon the handle of the same to automatically revolve thebit. The invention, however, has to do more particularly with that portion of the tool which forms the holder for the drill-bits not in use, and this in combination with the operating portion of the tool.

In the drawings illustrating our invention, Figure l is an elevation of the tool complete. Fig. 2 is a longitudinal section of the same. Fig. 3 is a sectional view through the plane x x of Figs. l and 2. Fig. 4L is a sectional view through the plane y y of Figs. l and 2. Fig. 5 is an end view of the bit-holding device. Fig. 6 is an elevation of one of the drill-points.

Similar reference-letters in the drawings represent like parts in all of the iigures.

Referring to the drawings, A is a tube, a part of the exterior of which is smooth, as at o, and the rest spirally ribbed, as at b, with several threads. The smooth portion of the tube A has its end screw-threaded to receive a nut C, correspondingly screw-threaded and having a conical end. In one end of this tube A a clip B is inserted, and this clip, together of the tube A.

shell D and causes the tube A to revolve when D is a cylindrical shell, which incloses the tube A in part, having at one end a disk CZ, with notches adapt-ed to receive the threads The disk CZ is fixed to the said tube is pushed axially in either direction. A spindle E, having a head e to form a shoulder, has coiled about it a spiral spring f,one end of which is iixed in the tube A,

while its opposite end bears against the shoul- 6o der formed by the head e of the said spindle E. The spindle E and spring f are inclosed in the shells of the tool and will be referred to hereinafter.

The handle of the tool is preferably made larger in diameter than the shell D, and is composed chiefly of three parts-viz., an inner metallic tube F, closed at one end, an outer metallic shell G, and an intermediate wooden body H, provided with cells longitudinally 7o formed therein. The shellGhas an end g. of small diameter screw -tlireaded within and adapted to iit over the screw-threaded end of the nut of the shell D. A disk I, perforated in a line concentrically as to the axis with a number of holes, is fitted and secured within the larger end of the shell G, and over this disk and shell is pivoted a cap K, provided with a single hole Z', coinciding with either of .the holes in the disk I and cells of the wooden 8o K is revolved and the hole Z comes opposite 9o leither of them. The head of the spindle or pin Zt is rounding, and the cap K when moved rides upon said pin, the latter returning to normal position, however, when the hole Z and it are coincident to lock the cap 95 and disk together over the cells I.

The exterior of the shell G near its upper end is numbered or lettered to indicate the several bits inclosed within.

The several bits for the tool are cylindrical Ioo The cap K is secured to the disk I in general form and Iluted on opposite sides to provide four cutting-edges and pointed at the end conically, while at the opposite ends of said bits rectangular grooves (four in number) are formed, corresponding with the angular formation of the splits in the jaws of the clip I3, previously described.

In the operation of the tool pressure is exerted upon the handle against the tension of the spiral spring E, and as the tube A, with its spirally-threaded portion, passesI through the n ut cl the bit in the lowerV end of the tool revolves, working its way into the material to be drilled. Vhen the pressure is withdrawn from the handle, the spiral spring forces the tube A out and the drill isrevolved in an opposite direction to clear the hole which is being formed. The movement of pushing and yielding is kept up until the hole is formed.

In the manufacture of our holders for the drill-bits we prefer touse the intermediate wooden body pierced with cells for the bits, so they may be completely separated from each other, although we may dispense with said wooden body and still have a goed holder. Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is-

1. The combination, in a drillingtol with the shell G, of the wooden iilling provided with longitudinal cells for the bits, the tube F, the disk I, cap K, having the hole Z coin- @ident with the drill-cells, and screw m, as and for the purpose specified.

In a drilling-tool, the combination, with the tube A, of clips t', inclosed in said tube, the spring between said clips, the pin passing centrally through said tubes, spring, and clips,.
