Letters Pate-nt No. 93,108, dated July 27, 1869.
IMPROVED DRILL-CHUCK.
The Schedule refen'edto in these Letters Patent and making part cf th 52m6- Tovall whom it may concern: l.
Bc it known that I, GEORGE W. MILLER, of Woonsocket, in the county of Providence, and State of Rhode Island, have invented a new and valuable Improvement in Drill-Chucks; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of' reference marked thereon.
vFigure l, of the drawings, ,is a side view, with drill, of my invention.
Figure 2 is a longitudinal section ofthe same.
Figure 3 is a cross-section thereof.
Figure 4, a top or bottom View of chuck.
Figure 5'is a perspective view of the saine.
My invention relates to chucks for holding drills; and
It Consists mainly in a novel arrangement of devices intended to serve as eicient means for the purpose named.
The letter A, of the drawings, represents a cylinder, having a thread on its inside, as shown, adapted to the thread on the outer surface of the shaftB, hereinafter described.
This cylinder has a small opening at its end, opposite the thread, adapted to the size of the shank of an ordinary drill, and is bevelled down at the point a, to providev a rest for the bevelled ends of the clutches s, described hereafter.
The letter'D represents a 1ing,.cut out in the manner shown on iig. 3, to provide suitable recesses and openings for the clutches and springs, next mentioned.
The letters s represent Iadjustable clutches, arranged in the recesses of ring D, as shown; and the letters 'u represent coiled springs, arranged in circular openings in said ring. Each end of these coiled springs is extended beyond and at right angles with the openings in which the springs are held, and is passed into a groove on the inner side of a clutch, s, in the manner shown on figA. When thus arranged, these springs serveto keep said clutches in their appropriate places. i It will be observed that both ends of chucks s are bevelled. By'this means, said chucks are adapted to rest against the bevelled part of cylinder A, at the point a, at one end, while the other fits inthe concave foot of the shaft B, nextment-ioned.
The letter B represents a'shaft, having an enlarged toot, as shown, upon which a screw is cut, adapted to the thread on the inner side of cylinder A. I also cut ont the foot of this shaft, at the point c, intol a concave shape, adapted to receive and operate the chucks\ s,iu
the manner hereinafter mentioned. The extreme inner points of chucks s have smal grooves, marked y, by which they are adapted to clasp the shank of a very small drill; when desirable 'so to do.V
To operate my chuck, I drop the ring D, 'with chucks s arranged therein, into the cylinder A, and allow it to rest against the bevelled part of said cylinder, at the point a. I then place the shank of the drill between chucks s, and insert shaft B into the cylinder, and screw it inward, thereby gradually forcing the concave c against the bevelled ends of the chucks, yuntil the shank of the' drill is clasped as iirmly as I desire.
What I claim as my invention, and desire to secure by Letters Patent, is
A chuck for holding drills, having cylinder A, ringV D, chucks s, springs v, and shaft B, constructed and arranged substantially as specified.
In testimony that I claim the above, I have hereunto subscribed my name, in the presence of two witnesses.
GEORGE W. MILLER. Witnesses:
ALBERT G. ROBINSON, GEORGE A. WrLBuR.
