To rtZ/l It'll/0777, zit may concern.-
Be it known that we, VVILLIAM hIITOHELL and JOHN F. MIT HELL, residing in Milwau kee, in the county of Milwaukee and State of WVisconsin, have invented new and useful Improvements in Bench-Drills, of which the following is a description, reference being rad to the accompanying drawings, which are a part of this specification.
This invention includes improved and novel features in bench drills which are found to be important and valuable in practical use and which are obvious on an inspection of the drawings and the description thereof herein.
The invention consists of the bench-drill, its parts, and combinations of parts, as herein described and claimed, or the equivalents thereof.
In the drawings, Figure 1 is a side elevation of the complete drill. Fig. 2 is a front elevation of the drill, the handle being broken away for convenience of illustration; and
Fig. 3 is a transverse section on line 3 3 of Fig. 1 looking downwardly. I
In the drawings, 4 represents a frame of suitable size and form for being readily secured removably to a bench and for mounting therein the operative parts of the device. The frame is an elongated structure adapted to be secured in a substantially vertical position temporarily to a bench or other fixed support to put the device in convenient position and suitably supported for use. The frame may be supported in any other position, though the vertical position will be mostly adopted. For securing the frame to the edge of a bench the rear part of the frame is provided with rearwardly-projecting brackets 5 5, the upper bracket 5 being provided with a set-screw 6, adapted to be turned against the surface of the bench interposed between the brackets 5 and 5, whereby the :l'rame is secured detachably to the bench.
The frame 4, at its upper end, is provided with a laterally-projecting and overhanging arm 7, elongated vertically at its free end, providing two shaft-bearings 8 8, within which the shaft or shank 9 is fitted revolubly, the shaft at its lower end being provided with a collar 10, that fits against the under surface of the lower bearing 8 and prevents the upward moving or displacement of the shaft, and at its upper end the shaft is provided with a crank-handle 11, into which the upper end of the shaft is fitted and secured rigidly, the end of the handle fitted about the shaft resting on the top of the upper bearing 8 and preventing the movement or displacement of the shaft 9 downwardly in its bearings.
The lower end of the shaft 9 is formed to serve as a chuck 12, it being provided with an axial socket extending from its outer end into the chuck or shaft, which socket is squared or faced to adapt it to receive and hold the squared or faced end of a drill or analogous implement.
To provide for holding the material to be operated on by a drill in the chuck 12, which material, as may be required in any particular case, must be held in position near to or at some distance from the. chuck and which as the drill proceeds with its work must be moved toward the drill and chuck, a material-holder 1.3 is provided, which is mounted adjustably toward and from the chuck 12 and opposite thereto on the frame 4.
The material-holder 13 is secured to and is advisably made integral with and projects laterally from a slide 14, fitted and movable vertically on ways 15 therefor on the front elongated edge of the frame 4. Advisably the ways 15 are formed on the front edge of the frame 4 by having that edge of the frame expanded laterally, forming laterallyprojecting ribs 16, and the slide 14, which fits against the flat front edge of the franie, is provided with clamping-fingers 17, which pass around and behind the ribs 16 and hold the slidemovably to the ways. For supporting and strengthening this movable relation of the slide 14 to the frame a flange 18 on the frame projects at the rear of the nontoothed edge of the slide 14 along the upper portion of the path of the slide, and the edge of the slide is adapted to bear movably against this flange, and a tongue 19, projecting from the flange 18, extends in front of the outer surface of the slide, thereby aiding the fingers 17 in holding the slide in position on the ways therefor on the face of the frame. The slide being in position on the ways, the lower end of the frame is advisably bent outwardly, forming a stop 20 to prevent the accidental escape of the slide from the frame downwardly.
For adjusting the slide vertically on the frame, and thereby moving the materialholder-13 toward or from the chuck 12, the
What We claim as our invention is a In a portable bench-drill, an elongated frame having a rigid arm projecting laterally toward the front, an elongated laterally-expanded slideway 15 on the front edge of the frame, a marginal flange 18 on and projecting at one edge in front of the laterally-expanded slideway, a slide fitted and movable endwise on the expanded slideway and bearing laterally against the marginal flange, a finger holding the slide to the slideway movably, a rack on that edge of the slide opposite its bearing against the marginal flange and roj ecting at a right angle away from a p ane through the axis of the drill-shaft and through the face of the slideway, a mutilated gear pivoted on the frame and provided with a handle and meshing with the rack on the slide adapted to move the slide up and down and to per mit its movement independently of the gear, and a material-holder on the slide in the proj cation of the axis of the drill-shaft and adapted by the movement of the slide to be brought nearer to and to be carried away from the drill-shaft.
In testimony whereof we aflix our signatures in presence of two witnesses.
