Patented 001;. 25,1881.
Nrrnn Partant @amera YILLIAM TUNSTILL, OF NEW YORK, N. Y.
MACHINE FOR DRILLING METAL.
SPECIFICATION forming part of Letters Patent No. 248,812, dated .October 25, 1881.
Application filed May 18, 1881.
To all lwhom it may concern Be it known that I, WILLIAM TUNSTILL, of the city and State of New York, have invented an Improvementin Drilling-Machines, of which the following is a specication.
Drilling-machines have been made with a frame that carries the drilling mechanism capable ot` being inclined, so that the drilling can be effected at an inclination to the bed or support for the article operated upon.
My invention relates to a drilling-machine that is adapted to hand use, and in which the standard that carries the drill can be inclined, and the bed upon which the article to be drilled rests can be inclined and moved to carry such article up to the tool.
In the drawings, Figure l is a side elevation of my improved drilling-machine, and by dotted lines the drilling mechanism is shown in an inclined position. Fig. 2 is a front elevation of the machine. Fig. 3 is an elevation showing a modification of the arm that supports the drilling-tool, and Fig. 4. is a plan ot' such arm.
The bed k, upon which the article to be drilled rests,is provided with a central shaft, 7c', that passes through bearings in the carrier l, and this bed and shaft can be revolved, if desired, in their bearings. The carrier Z is between two vertical frames, b', that are cast upon or bolted to the base-plate a; and mis a pivot-bolt passing through the frames b and through the carrier l, and upon this pivot the carrier and bed can be swung, so that the bed will be either horizontal or at an inclination.
In the vertical frames b there are segmental slots, and the bolt a passes through these segmental slots and through the carrier l, so that the parts can be clamped firmly in place by this bolt a when the bed has been properly placed in presenting the article uponthe bed stothedrill,hereinafterdescribed. Thecarrier l is L-shaped, the vertical part being parallel with the shaft k and the horizontal part projecting beyond the edges of the frames b', and
the shaft 7c can be moved endwise in its bearingsin said carrier l, and th ereis a pivot-bearin g beneath the horizontal part of this carrier l for the pivot p of the lever p, and the short 5o end of this lever is against the lower end of (No model.)
the shalt k', so that power can be applied to move said shaft k endwise, and the bed, with the article to be drilled, toward the drill, and for this purpose a movableweight, r, may be applied to the lcverp as a counterpoise to the bed and the article upon it.
The segmental han ges b are cast with or bolted to the base-plate a, and between them is the foot of the standard c.
d is a pivot-bolt passing through theflanges b and standard c, and upon this bolt the standard can be swung, while e is a clampingbolt passing through the standard and. through segmental slots in the lianges l), by means of which the parts can be clamped to hold the standard vertically or at an inclination. rIhe dotted lines in Fig. l show the standard as inclined. Theupperendofthestandardcisround, and passes through an eye at the end ot' the arm g, and h is a set-screw by means of which the arm is held firmly to the standard. This allows the arm and drilling mechanism to bc raised or lowered upon the standard, or to be turned around horizontally to a greater or less extent, and thereby bring the drill to the desired place upon the article to be drilled.
The drill tand the chuck u holding the same are to be of any desired character.
The arbor l0 for the drill is provided with a pinion, w, and n is a gearwheel upon a hori zontal stud or gudgeon, and a crank or hand wheel, s, is employed for rotating the wheel c, pinion w, arbor l0, and drill.
In Figs. l and 2 the arm gis shown as adapted to receive and clamp a drill-stock, z', with a breastpiece at the upper end, and in Figs. 3 and 4 the drill-stock and breast-piece are dispensed with.
The means for holding the drill-arbor and rotating the drill-chuck and drill by hand, and the devices for supporting and adjustingthe article to be drilled, enable the workman to opera-te the drilling` mechanism with facility.
I claim as my inventionl. The combination, ina drilling-machine, of the bed 7c, shaft k', pivoted carrier l, clamping-- bolt n, slotted frames b', and leverp, substarr tially as set forth.
2. The combination, in adrilling-machine, of
the standard c, segmental anges b, pivot-bolt TOO- d, elamping-holt e, movable arm g, elampingclamping mechanism, and the lever p for movserew 7L, drill, gearing, and crank for actuating ing the bed toward the drill, as set forth. lo the drill, substantially as set forth. Signed hy me this 16th day of May, A. D.
