DRILL.'
SPECIFICATION forming part of 'Letters Patent NO. 739,946, dated September 29, 1903. Application led October 25, 1902. Serial Ng. 128,789. (No model.)
To MZ whom t may concern.-
Be it known that I, CHRISTOPHER STRAUB, a citizen of the United States,residing at Long Island City, in the county of Queens and State of New York, have invented new 'and useful Improvements in Drills, of which the following is a specification.
N The drill shown belongs to the class generally known as ratchet-drills, although a clutch or other mechanism not strictly ratchet has been shown in this art, and, moreover, the invention is not aected by this detail.
By means of this invention a brace can be obtained for the tool other than the customary center or hard-steel point. Say, for example, a floor of a 'room is to be bored or drilled, then by a tube or the like-say a piece of piping of sucient length and diameter-a brace for the tool can'be obtained at the ceiling of the room or other comparatively distant point. Such bracing at a distant point can be obtained without theeasy working or the steadiness of the tool being interfered with, so that steady work can be done and quivering avoided. v
This invention is illustrated in the annexed drawings, in which- Figure l is a sectional elevation of a drill embodying this invention. Fig. 2 shows a brace.
Certain parts of the drill are well knownas, for example, the sleeve g, with center or steel point t', and also the ratchet-wheel orv extension or brace piece. This ange fis shown below the top ofthe sleeve g, and a tubular extension or pipe e slipped over or about the sleeve against the'iiange and suitably braced or seated against a xed body at its other end will give a brace for the tool Such as ordinarily obtained by aid of the center.
Ball-bearings for the flange will allow easy rotation of the latter, or rather of the drill, when braced by aid of the flange. The balls can race or be supported on the shoulderpiece. A practical form of construction is to have the {lange-washer somewhat cup-shaped or overhanging to keep the balls confined on the shoulder-piece.
What I claim as new, and desire to secure by Letters Patent, isv l. A drill comprising a sleeve, a looselymounted supporting-flange arranged below `said sleeve, and a tubular bracing extension detachably mounted upon said flange, supported thereby and surrounding said sleeve.
2. A drill comprising a sleeve, a shoulderpiece screwed into said sleeve, a screw attached to a drill-holder and extending in the shoulder-piece, and a ange loosely mounted on the shoulder-piece.
v3. A drill comprising a sleeve, a shoulderpiece screwed into the sleeve, a screw in the shoulder-piece,a flange loosely mounted on the shoulder-piece, and a tubular bracing extension surrounding said sleeve, detaohably mounted upon and supported by said ange.
4. A drill comprising a sleeve, a brace-supporting flange loosely mounted below said sleeve, a tubular bracing extension surrounding said sleeve and detachably mounted upon and supported by said Iiange` and suitableball-bearings for the said flange.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. l
CHRISTOPHER STRAUB. Witnesses:
ALEX. S. WILLIAMS, E. F. KASTENHUBER.
