IMPLEMENT FOR ROTATING TOOLS.
SPECIFICATION forming part of Letters Patent No. 423,971, dated March 25, 1890.
Application filed November 6, 1889. Serial No. 329,444:- (No model.)
To all whom it may concern.-
Be it known that 1, AUGUST VEDoE, a subject of the King of Sweden, residing in the city of Stockholm, in said Kingdom, have invented a certain new and useful Implement for Rotating Tools for Boring, Milling, Rasping, Grinding, and Polishing; and Ido hereby declare the following to be a sufficiently full, clear, and exact description thereof to enable others skilled in the art to make and use the said invention, reference being had to the accompanying drawings, in which-.
. Figure 1 shows a top view or plan of the invention; Fig. 2, a front elevation thereof; Fig. 3, a central vertical section thereof; Fig. 4, a horizontal section in the plane indicated by the dotted line X X in Figs. 2 and 3, and Fig. 5 shows a central transverse section of a modification of this invention.
The same parts are indicated by like reference-marks in the several figures.
The object of this invention is to furnish a convenient instrument whereby the operator by the use of one hand only can propel rotatively and control in direction and pressure or force of application rotating tools, such as drills, counter-sinks, reamers, millingcutters, and grinding and polishing wheels; and it consists in a rotating spindle and a connected fly-wheel propelled by a speed-.
multiplying wheel, it being suitably arranged in a stock adapted to be held in the palm of the hand by pressure with the thumb, and propelled by a reciprocating plate operated by the fingers of the same hand and connected with the arbor of the multiplyingwheel by an apparatus for converting the reciprocating into rotary motion.
1 represents the frame or stock of the apparatus, which is of a form and size adapted to fill the space between the thumb and palm of the hand.
2 is a drill staff or spindle fitted upon and turning in a bearing 3, formed in the lower part of the stock 1, and supported at the upper end by a pivotal bearing 4 in the stock. Upon the spindle 2, formed in and fitted thereto, is a pinion. 5, which engages in a spurwheel 6 of much greater diameter, so as to be turned rapidly thereby. The wheel 6 is fitted upon and turned by a crank-shaft 7. The crank 7 is fitted to turn on bearings 8 and 9, respectively formed in the lower and upper ends of the stock 1.
Upon the wrist 15 of the crank-shaft 7 1s fitted so as to turn freely a link or connecting rod 10, upon the outer end 11 of which is a curved fin ger-plate 12, adapted to be grasped by the fingers of the operator. The rod 10 passes between guides 13 and 14c, and by reason of its connection to the crank-wrist 15 and the guiding of the rod 10 by the guides 13.and 14:, describes a reciprocating and oscillatory motion, so that an operator by the motion and pressure of the fingers upon the plate 12 propels a crank-shaft and spur-wheel rotatively, and imparts rapid rotary motion to the drill-spindle 2. A second spindle 16, propelled by a spindle 17 engaging in the teeth of the spur-wheel 6 and turning in bearings 18 and 19 in the stock 1, carries with it a fly-Wheel 20, which by its momentum equalizes the motion of the rotating parts and serves to effect the outward or returning stroke of the crank-wrist 15, connecting-rod 10, and finger-plate 12. The oscillatory motion of the finger-plate 12 enables the operator, by making pressure upon one of the edges of it, to start the crank into motion when the crank 15 and rod 10 are in the same plane, or in the dead-center.
In the modification shown in Fig. 5, instead of a crank-shaft to carry and propel the spurwheel 6 a ratchet-wheel and a pawl propelled by the finger-plate 12, and a rod 10, returned by a spring 21, are employed, which construction is more readily started in operation than the crank, but has not such an easy reversal of movement as the crank and connectingrod produces.
The rotary motion produced by this implement is continuously in the same direction, and is adapted'to the class of cutting, polishing, and boring tools ordinarily employed in conjunction with small lathes.
I am aware that braces for operating drills and other rotative tools have been made in which a tool-bearing spindle was propelled by gearing at a higher velocity than the crank by which the brace was operated; also, that drill-braces operated by pawl-and ratchet gearing have been used, all of which implements required other support and guidance than that of the hand used in propelling them. Neither of these do I claim; but
\Vhat I do claim is- 1. An improved implement for guiding and propelling rotating tools, consisting of a rotating tool-supporting spindle having bearings in a stock 1, adapted to be heldbetween the palm and thumb of the operator, in combination with a reciprocating finger-plate adapted to be Worked by the fingers of the same hand, and means for converting such reciprocating motion into continuous rotary motion of the tool-supporting spindle, substantially as set forth.
2. In an implement for propelling and guiding rotating tools by hand, the combination of the stock 1, adapted to be held between the thumb and palm of the hand and furnishing the support for a drill-spindle and a fly-Wheel, and an arbor therefor arranged and connected with a reciproeatingfinger-plate, substantially as set forth and described.
