Drills. No. 134,237, Patented De.24,1872.`
' UNITED STATES PATENT OFFICE.
CHARLES H. AMIDON, OF MILLERS FALLS, MASSACHUSETTS.
IMPROVEMENT IN DRILLS.
To all rwhom it may concern:
Be it known that I, CHARLES H; AMrDoN, of Millers Falls, in the county of Franklin and State of Massachusetts, have invented a new and useful Improvement in Hand-Drills 5 and I do hereby declare the folowing to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, in which- Figure l is a perspective view of my apparatus in operative position, and Fig. 2 is a side elevation of the same.
This invention relates to that class of handdrills intended for Vuse by blacksmiths and other artisans whose business does not warrant the employment of expensive special tools for such and similar purposes; and it consists in a frame having a crank-shaft, drillstock, and the requisite gears mounted thereon, and provided with a clamp whereby the said frame may be secured to one of the jaws `0f a common vise in such position that the other of said jaws, moved by the vise-screw,
may be employed to feed the work to the drill.
That others may fully understand my invention, I will particularly describe it.
`A is the frame, which I prefer to construct froma single lat bar of wrought-iron, of proper width and thickness, and bent substantially in the form shown. Perforations in line through the bar A at a a form bearings for the crankshaft B, and a cog-wheel, C, is keyed or otherwise secured to the end of said crank-shaft outside of said frame. At points d d other perforations in line form bearings for the short shaft D, which carries the pinion E in gear with the pinion C and the drill-stock F. A cla-mpbar, G, provided at one or both ends with setscrews H, is rigidly fixed transversely across the frame A a little higher than the axis of the shaft D, and thereby the frame A may be secured to one of the jaws I of a common vise in such position as will bring the axis of the shaft D opposite and perpendicular to the face of said jaw, whence it will follow that, it' a drill, f, be placed in the stock F, its point will be opposed to the face ofthe other of said jaws I', and the piece of metal to be perforated may be placed in front of said jaw I and fed to the drill by means of the vise-screw J.
This machine is herein shown and described in its simplest form. It may be constructed much more elaborately-for instance, with a frame of cast-iron, with boxes fitted for the crank-shaft, and with combination gears for different speeds, without in anywise changing the principle ot' my invent-ion. The gears C E should be made interchangable by securing them upon their shafts in some manner which will permit their easy removal and replace- Witnesses:
R. D. O. SMITH,
GEO. BARTLE.
