SP'EGIFICATIO forming part'of Letters Patent No. 693,166, dated February 1 1, 1902. Application tiled October 26, 1901. `'Serial No. 80,054. (No model.)
To @ZZ whom, t may concern:
Be it known that I, FRANK I. SHEK, a cirizen of the United States,residing in New York, borough of Brooklyn, and State of New York, have invented certain new and useful Improvements in Supports for Hand-Drills, of which the following is a specification.
This invention relates to an improved support for hand-drills by means of which the drill can be used in a more effective manner and in different positions relativelyV to the work to be performed, so that the efliciency and usefulness of the hand-drill are considerably enlarged; and the invention consists of a support for hand-d rills,consisting of a frame having a main piece, an upper angular piece having an aperture at its outer end for engaginglthe threaded spindle of the hand-drill and an aperture adjacent its bend for receiving the pin of the upperend of the main piece, and an angular lower end which is provided with an angular clamping-piece for attaching the support to a bench or to the work to be operated on, while the main portion of the drill is guided in a holder that is permanently attached to the drill-stock, said upper end of the frame being detachable from the middle portion, so, as to permit the removal of the supporting-frame from the drill when it is desired to use the same in the usual manner.
In the accompanying drawings, Figure l represents a side elevation of my improved support for hand-drills, showing the drill applied in a horizontal position to a stationary piece of work in which holes are to be drilled. Fig. 2 is a side elevation of my improved support for drills, showing the drill applied to a bench or other support and the work placed in position thereon. Fig. 3 is a side elevation showing the supporting-frame removed from the drill, so that the same can be used in the ordinary manner. Figs. 4. and 5 are horizontal sections on lines 4 -1 and 5 5, Fig. 2. Fig. Gis a side elevation of the main portion of my improved support, shown as detached from the drill; and Fig. 7 is a side view of the thumb-screw for connecting the paris of the supporting-frame.
Similar letters of reference indicate corresponding parts.
Referring to the drawings, A represents a hand-drill of the usual approved construclgears of the drill in the usual manner.
tion, and B my improved support for the same, which is formed of a U-shaped frame composed of two pieces -a main piece b, havlng an angular end piece b at its lower end, and a second angular detachable end piece b2 at its upper end, which is applied to the 'corresponding opening in the angular end piece b2. Y To the lowerV end of the main piece 1J is attached an angular piece d, one leg of which, adjacent the main' piece, is slotted and guided thereon bya headed screw d', while the other leg extends parallel with the lower end piece b and is engaged by a thumbscrew d2, so that the angular piece d can be adjusted relatively to the end piece b and either clamped to asuitable bench or other support, as shown in Fig. 2, or directly to the work in whichholes are to be drilled, as shown in Fig. l. The main piece b is guided in a holder C, the shank of which is riveted, screwed, or otherwise attached to the drill-stock A', said'holder being preferably made of suitable sheet-steel and provided with a rectangular opening for the main piece b of the supporting-frame, as shown in Fig. 4. The supporting-frame B permits the application of the drill for many purposes ina more convenient manner, as it can be clamped directly to the work when holes are to be drilled in the same, as shown in Fig. 1, or by placing the Work below the drilling-tool proper, as shown in Fig. 2, in lwhich case the support is clamped to a bench or lother support. In case it should loe desired to usevt-he drill without the support the main piece b is disconnected from the upper end piece b2 by unscrewing the clamping-screw b3, so that the main frame can be drawn out longitudinally from the holder C and detached from the drill. The holder C is then used as a handle for holding the drill by one hand, while the other hand operates the crank-handle and transmitting- The upper end piece b2 is preferably permitted to remain in position on the threaded end of the drill-spindle, though it can also be removed therefrom by detaching the rest-piece at the end of the same. In most cases, however, it is not necessary to remove the upper end piece.
My improved supporting-frame for handdrills is preferably made of wrought-iron and forms a cheap and eieetive attaohment by which the use of the drill is greatly facilitated and its scope considerably enhanced.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- A support for hand-drills, consisting of1 a main piece, a holder supported permanently thereon and provided with a rectangular opening, said main piece having an angular lower end, an angular adjustable clamping-piece guided on the lower end of the main piece, a
