Description: |
| Emil Neuhook - patent attorney
My invention relates to an angle drill, and more particularly to a drill of this type which is to be attached to the chuck of an ordinary or master drill, although the source of power used to operate the drill may be directly applied to the driving shaft or prime mover of this angle drill. Many places are encountered in or on objects where holes are to be drilled which ordinary or master drills cannot be used for; for example, when drilling holes in recessed places or places adjacent upstanding flanges or ledges. It is therefore one of the objects of my invention to provide an angle drill in which the driving shaft or prime mover can be entered and secured in the chuck of an ordinary or master drill, and which is of comparatively small size so that it may be operated in close quarters or adjacent what ordinarily would be considered obstructions to an ordinary or master drill, or what may be termed a conventional drill. A further object of my invention is to provide an angle drill which may be employed as an accessory to a master drill, or which may itself be used as a master drill; its design and construction, however, being such that it is particularly adapted as an adjunct to a conventional or master drill for use in places inaccessible to the latter. A still further object of my invention is to provide an angle drill which, as an accessory to a master drill, assures uniform rotation for the drill-bit, during operation, and furthermore, which by reason of its construction, practically eliminates lateral or radial stresses of the moving parts of the drill within their bearings, thus assuring longer life and greater efficiency.
