Description
WILLIAM J. JOHNSQN,
OF NEWTON, AND GEORGE TAINTER, OFl
WATERTOWN', MASSACHUSETTS.
Letters Patent No. 95,483, dated October 5, 1869.
IMPRQ'VBMENT IN BORING-TOOL.
The Schedule referred to in these Letters Patent and making part of the same.
Be it known that we, WILLIAM J. JOHNSON, of Newton, and GEORGE TAIN'rER, of Watertown, in
the State of Massachusetts, have invented a new and useful Improved Boring-Tool, of which the following, with the accompanying drawings, is a full description.
The nature of our invention consists in producing a rotary motion in a drill or bit, by pressing it against the object to be perforated; and our object is to `pro duce' a tool which shall automatically revolve and bore, by means of a straight forward and back movement of the handle toward and from the substance to be bored, and by means the most convenient'for/manipulation.
, Figure l is a plan view of the tool.
Figure 2'- is a section, with the many-threaded screw-tube forced intolthe case Figure 3 is a section, with the screw-tube or spindie out.
Figure 4 is a view ofthe many-threaded screw-y nut. y
Figure 5 is a partially-sectional View of the case and nut, and a partial plan view of the spindle, spring, and guide.
In thevdrawingsx A B is a hollow case, somewhat like apencil-case,
made in two parts.
a. is a screw-cap upon the but or handle-end.
b is a hollow coupling-nut, having screw-threads on the outside, to which the ends of A B are screwed or coupled, Sand also having a many-threaded female screw on the inside, for the many-threaded screwtube or spindle, to be hereafter described.
E is a hollow tube, with a many-threaded screw cut ouits outer side, so as to run-in and out of the many-threaded screw-nut l1.
O is a prolongation of E, and may be made hollow or solid. l It is better hollow. It is also smaller than E in diameter, although not necessarily.
e is a guide-nut or cap, screwed into the end of B, and through which C passes back and forth.
Between E and O is .a shoulder, which strikes against 'the guide-nut or cap e, and prevents the further advance forward of E.
D is the bit, giinlet, borer, or boring-point, tightly fastened, near its inner end. into a solid chuck or reinforce G.
d is a conical screw-cap, screwed on to the end of C, through the end of which D passes, and against /which, ou the inside, G presses. s
f is a spiral spring, enclosed in the case andthe many-threaded hollow tube E, and with one end pressing against the inner end of the spindle O.
The other end rests ona step, e, of a guide-rod F `the end of e resting against the screw-cap a. The
guide-rod may be dispensed with, but it is better as it is. l
When the screw-cap d is screwed on, the shoulder g, of the solid chuck or reinforce G, ofthe borer D, will be pressed firmly against the end of the tube C.
If the end of C and the under side of g be serrated, it may be found advantageous to prevent any separate revolution of D.
The modeof operation is as follows:
The part A being held in the hand, D is pressed against the substance to be perforated. A being pressed forward trom the position in figs. 1 and 3 to that in fig. 2, the hollow screw-spindle E O'is driven V backward through the screw-nut b,.and' against the spiral springf, and in so doing, D is rapidly revolved, and bores its way into the wood, 85e. The pressure of the'hand being relaxed, by tlie action of thev spring f the parts return to the position of tif. 3, when the forward pressure of the hand again continues the perforation.
The screw-tube may be arranged -to have its screw inside; the spiral spring may he arranged outside the.
tube; butwe have found the methods abovementioned the best and cheapest.
The chuck or reinforce G may be struck up from wire, and ydifferent bits or bores ,may each be furnished with suoli a reinforce, and, for many purposes and reasons, this is better than having one chuck fitted to accommodate dierent-sized shanks of bits or borers.
What wc claim, is.-
1. The boring-tool, constructed and arranged, as to y v its several parts, substantially as described.
2. The screw-tube, constructed substantially as set forth, in combination with the screw-nut and case, when constructed and arranged substantially as shown and described.
3. The screw-tube, with its screw-nut, spiral spring,
and borer or bit, severally constructed -and arranged to operate substantially as shown and described.
44. The screw-tube, nut, spiral spring, and guiderod, severally constructed and arranged to operate in combination, substantially as'shown, and for the pur- Y poses described.
In testimony whereof, we have hereunto subscribed our names.
WM. J. JOHNSON. GEORGE TAINTER.
